Description

Communication method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communication method and apparatus.

Background

There are three major application scenarios in the fifth generation (5G) mobile communication system and in future mobile communication systems: enhanced mobile broadband (eMBB), high-reliability and low-latency communications (URLLC), and massive machine type communications (mtc).

At present, in order to meet the requirements of ultra-high reliability and low-delay transmission of URLLC service, when time-frequency resources of URLLC transmission and time-frequency resources of eMBB transmission are overlapped, two schemes are provided for ensuring the reliability and low-delay of URLLC transmission.

The first scheme is as follows: when the network device prepares or has scheduled the URLLC transmission on the time-frequency resource where the eMBB transmission is being sent or is about to be sent, an uplink cancellation (UL cancellation) mechanism may be employed to ensure reliability and low latency of the URLLC transmission. The uplink cancellation mechanism is as follows: and the terminal equipment with URLLC service needing transmission sends a scheduling request to the network equipment. The network device schedules appropriate time-frequency resources for the network device as soon as possible to meet the delay requirement of the service. At this time, the network device may have already scheduled the current time-frequency resource to one or more other terminal devices for the eMBB transmission. If two services are transmitted simultaneously, the URLLC service will be interfered by the eMBB service, resulting in a serious decrease in reliability. Therefore, the network device needs to reschedule these time-frequency resources to the high priority URLLC traffic transmission. Specifically, the network device first sends indication information 1 to the eMBB UE, where the indication information 1 is used to indicate that the network device is about to schedule time-frequency resources for URLLC transmission. After receiving the indication information 1, the eMBB UE suspends the uplink data being transmitted on the corresponding time-frequency resource or cancels the uplink data to be transmitted.

Scheme II: when the network equipment schedules eMBB transmission on scheduling-free time-frequency resources, a power control mechanism is adopted to ensure the reliability and low delay of URLLC service transmission. To meet the latency requirement of URLLC transmission, the network device may configure it with a schedule free/configured schedule resource. When URLLC UE has uplink data to be transmitted, the uplink transmission can be directly carried out on the pre-configured scheduling-free time frequency resource. The power control mechanism refers to: and the network equipment sends indication information 2 to the scheduling-free URLLC UE, wherein the indication information 2 is used for indicating the time frequency resource of eMBB transmission scheduling on the scheduling-free time frequency resource. After receiving the indication information 2, the non-scheduled URLLC UE needs to increase transmission power if it is ready to perform uplink transmission on the indicated time-frequency resource, so as to ensure reliability of URLLC transmission to a certain extent.

However, by implementing the above two schemes, the network device needs to transmit two formats of indication information respectively to instruct different types of terminal devices to perform corresponding operations. Therefore, the system complexity is high, and the communication efficiency is reduced.

The embodiment of the application provides a communication method and device, which are beneficial to reducing the complexity of a system.

In order to better understand the embodiments of the present application, a system architecture to which the embodiments of the present application can be applied is described below.

Fig. 1 is a schematic diagram of a communication system according to an embodiment of the present application. As shown in fig. 1, the communication system includes a network device and a terminal device 1, a terminal device 2, a terminal device 3, and a terminal device 4. The terminal devices 1 to 4 are connected to the network device in a wireless manner. Fig. 1 is a schematic diagram of a communication system provided in the present application, and fig. 1 illustrates an example of a communication system including a network device and four terminal devices. Of course, the communication system may include more than four or less than four terminal devices. Alternatively, the communication system may further include other devices, for example, a wireless relay device, a wireless backhaul device, and the like, which is not limited in the embodiment of the present application.

The technical scheme of the embodiment of the application can be applied to various communication systems. For example: a Long Term Evolution (LTE) system, a fifth generation (5G) mobile communication system, such as a New Radio (NR) system, or other new mobile communication systems in the future.

The network device in the embodiment of the application is an access device which is accessed to the mobile communication system by the terminal device in a wireless mode. For example, the network device may be an evolved NodeB (eNB), a Transmission Reception Point (TRP), a next generation base station (gNB) in the NR system, a base station in another future mobile communication system or an access node in the WiFi system. The embodiments of the present application do not limit the specific technologies and the specific device forms used by the network devices. The network device provided by the embodiment of the present application may be composed of a Central Unit (CU) and a Distributed Unit (DU), where the CU may also be referred to as a control unit (control unit), and a protocol layer of a network device, such as a base station, may be split by using a structure of CU-DU, functions of a part of the protocol layer are placed in the CU for centralized control, and functions of the remaining part or all of the protocol layer are distributed in the DU, and the DU is centrally controlled by the CU.

The terminal device in the embodiment of the present application is an entity, such as a mobile phone, on the user side for receiving or transmitting signals. A terminal device may also be referred to as a terminal (terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc. The terminal device may be a mobile phone (mobile phone), a wearable device, a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal device, an Augmented Reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a wireless terminal in self-driving (self-driving), a wireless terminal in remote surgery (remote management), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety, a wireless terminal in city (smart city), a wireless terminal in smart home (smart home), and so on. The embodiment of the present application does not limit the specific technology and the specific device form adopted by the terminal device.

The network equipment and the terminal equipment can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; can also be deployed on the water surface; it may also be deployed on airborne airplanes, drones, balloons, and satellites. The embodiment of the application does not limit the application scenarios of the network device and the terminal device.

Wherein, the terminal device 1 is configured to send scheduling-based eMBB transmission, and the terminal device 2 is configured to send scheduling-based URLLC transmission. Terminal device 3 and terminal device 4 are used to send a schedule free URLLC transmission. The terminal device 3 is arranged to send a schedule-free low priority URLLC transmission. Terminal device 4 is configured to send a schedule-free high priority URLLC transmission.

The following describes scheduling based eMBB transmission, scheduling based URLLC transmission, and scheduling free URLLC transmission.

Scheduling-based eMBB transmission refers to: when the terminal device is ready to send an eMBB transmission, it needs to send a scheduling request to the network device. After receiving the scheduling request, the network device allocates transmission parameters such as time-frequency resources, Modulation and Coding Scheme (MCS), power control, and the like for the eMBB transmission. After receiving the transmission parameters allocated by the network device, the terminal device sends the eMBB transmission according to the transmission parameters. The eMBB transmission is a scheduling-based eMBB transmission. For simplicity of description, the eMBB transmission in the embodiments of the present application refers to scheduling-based eMBB transmission.

Scheduling-based URLLC transmissions refer to: when the terminal device is ready to send a URLLC transmission, a scheduling request needs to be sent to the network device. After receiving the scheduling request, the network device allocates transmission parameters such as time-frequency resources, MCS, power control, and the like for the URLLC transmission. And after receiving the transmission parameters distributed by the network equipment, the terminal equipment sends the URLLC transmission according to the transmission parameters. The URLLC transmission is a scheduling-based URLLC transmission.

The scheduling-free URLLC transmission means: when the terminal device is ready to send URLLC transmission, the terminal device may directly send URLLC transmission on a scheduling-free time-frequency resource of a scheduling-free configuration (grant-free configuration/configured grant configuration) without going through a process of "sending a scheduling request to the network device and the network device sending transmission parameters according to the scheduling request". The URLLC transmission is the scheduling-free URLLC transmission.

The network device may pre-configure one or more scheduling-free configurations for URLLC traffic for scheduling-free transmission. For type two scheduling free configuration, the network device sends an activation signaling to activate the scheduling free configuration. After receiving the activation instruction, the terminal device can send URLLC transmission on the scheduling-free time-frequency resource configured without scheduling. The scheduling-free configuration may be configured by higher layer signaling. The higher layer signaling may be Radio Resource Control (RRC) signaling, or may also be System Information Blocks (SIBs), Master Information Blocks (MIBs), or the like. The schedule-exempt configuration may include one or more of the following configurations: frequency hopping (e.g., intra-slot frequency hopping, inter-sub-slot frequency hopping), Demodulation Reference Signal (DMRS) configuration, MCS table selection, MCS table conversion precoding, and selection of dynamically or semi-statically configured beta-offset (where beta-offset refers to a resource occupied by uplink control information on a physical uplink shared channel), resource allocation type, Resource Block Group (RBG) size of a Physical Uplink Shared Channel (PUSCH), closed-loop power control procedure, open-loop power control parameters (including P0 and alpha, where P0 is a target snr of a Signal received by a network device, and alpha is a path loss compensation factor), number of HARQ (hybrid automatic repeat reQuest) procedures, PUSCH repetition number, redundancy version, period, time domain resource allocation, frequency domain resource allocation, Antenna port, precoding and layer number, Sounding Reference Signal (SRS) resource indication information, modulation and coding scheme table and transport block size used by PUSCH, frequency hopping offset, and path loss Reference index.

Where different URLLC transmissions may have different priorities. The network device may indicate the priority level of the schedulable URLLC transmission in the following two ways. The first method is as follows: for type two scheduling-free configuration, the network device needs to send an activation signaling for activating the scheduling-free configuration. The activation signaling may indicate via an information field the priority level of URLLC transmissions transmitted with the scheduling free configuration. The second method comprises the following steps: for scheduling-free configuration which does not need to be activated, when the network device configures the scheduling-free configuration for the terminal device through a high-level signaling, the network device may indicate, through the high-level signaling, the priority level of URLLC transmission transmitted using the scheduling-free configuration. The terminal equipment can determine the priority level of the URLLC transmission transmitted by the terminal equipment according to the indication of the network equipment. Of course, the network device may also indicate the priority level of the scheduling-free URLLC transmission by other ways, which is not limited in this embodiment of the present application.

When the time frequency resources of eMBB transmission and the time frequency resources of URLLC transmission are overlapped, two schemes can be adopted to ensure the reliability and low delay of the URLLC transmission. The first scheme is as follows: when the network device prepares or has scheduled the URLLC transmission to the time-frequency resources where the eMBB transmission is being sent or is about to be sent, the network device may send indication information 1, where the indication information 1 carries the time-frequency resources of the URLLC transmission based on the scheduling. After receiving the indication information 1, the terminal device 1 suspends the uplink data being transmitted or cancels the uplink data to be transmitted in the time-frequency resource indicated by the indication information 1. Therefore, the time frequency resources adopted by URLLC transmission and eMBB transmission are not overlapped, and the reliability and low time delay of the URLLC transmission are ensured. Scheme II: when the network device schedules the eMB transmission on the scheduling-free time-frequency resource, the network device sends indication information 2, and the indication information 2 carries the time-frequency resource of the eMB transmission. After the terminal device 3 (or the terminal device 4) receives the indication information 2, if the terminal device 3 (or the terminal device 4) prepares to perform uplink transmission on the time-frequency resource indicated by the indication information 2, the transmission power needs to be increased, so as to ensure reliability of URLLC transmission to a certain extent.

However, with the above two schemes, the network device may send two formats of indication information respectively to indicate different types of terminal devices to perform corresponding operations. Designing the indication in two formats increases the complexity of the system while requiring more standardization effort. In addition, it is also easy to cause malfunction of the terminal device. For example, it is possible for all terminal devices to receive indication information 1 and indication information 2. After the terminal device 2 and the terminal device 3 (or the terminal device 4) interpret the time-frequency resource indicated by the indication information 1, the time-frequency resource indicated by the indication information 1 suspends the uplink data being transmitted or cancels the uplink data to be transmitted. Or after the terminal device 2 and the terminal device 3 (or the terminal device 4) interpret the time-frequency resource indicated by the indication information 1, if the terminal device 2 and the terminal device 3 (or the terminal device 4) prepare to perform uplink transmission on the time-frequency resource indicated by the indication information 1, the terminal device 2 and the terminal device 3 (or the terminal device 4) may increase transmission power. In practice, however, the purpose of the network device sending the indication information 1 is to enable the terminal device 1 to suspend the uplink data being sent or cancel the uplink data to be sent in the time-frequency resource indicated by the indication information 1 after receiving the indication information 1.

In the embodiment of the application, a unidirectional communication link from an access network to a terminal is defined as a downlink, data transmitted on the downlink is downlink data, and the transmission direction of the downlink data is called as a downlink direction; the unidirectional communication link from the terminal to the access network is an uplink, the data transmitted on the uplink is uplink data, and the transmission direction of the uplink data is referred to as an uplink direction.

The resources described in this embodiment may also be referred to as transmission resources, which include one or more of time domain resources, frequency domain resources, and code channel resources, and may be used to carry data or signaling in an uplink communication process or a downlink communication process.

The transmission or reception of traffic includes transmission or reception of traffic-related data (data) or signaling (signaling).

In the embodiments of the present application, "network" and "system" represent the same concept, and a communication system is a communication network.

It is understood that, in the embodiments of the present application, a terminal and/or a network device may perform some or all of the steps in the embodiments of the present application, and these steps or operations are merely examples, and other operations or variations of various operations may also be performed in the embodiments of the present application. Further, the various steps may be performed in a different order presented in the embodiments of the application, and not all operations in the embodiments of the application may be performed.

The application provides a communication method and device, which can reduce the complexity of a system and avoid misoperation of a terminal. The following further describes the communication method and apparatus provided in the present application.

Referring to fig. 2, fig. 2 is a flowchart illustrating a communication method according to an embodiment of the present disclosure. The execution subject of step 201 is a network device, or a chip in the network device. The execution subject of step 202 is the first terminal device, or a chip in the first terminal device. The execution subjects of step 203 and step 204 are the second terminal device or the chip in the second terminal device. The following description will take as an example the network device, the first terminal device, and the second terminal device as execution subjects of the methods. As shown in fig. 2, the communication method includes the following steps 201 to 204, wherein:

201. the network device transmits the first indication information.

The first indication information is used for indicating a first time-frequency resource, and the first indication information includes first information; the first information is used for indicating the first terminal equipment to silence the uplink data transmission on the first time-frequency resource; or, the first information is used to instruct the second terminal device to adjust the transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource. For example, the first indication information may be Downlink Control Information (DCI).

For example, if the first information is used to instruct the first terminal device to silence uplink data transmission on the first time-frequency resource, the first information is not used to instruct the second terminal device to adjust transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource. If the first information is used to instruct the second terminal device to adjust the transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource, the first information is not used to instruct the first terminal device to silence the uplink data transmission on the first time-frequency resource.

Optionally, the first information is represented by a first information field in the first indication information, and the first information field may contain one bit or multiple bits, or the first information is carried in an information field (field) of the first indication information, for example, the first information is carried in a header of the first indication information. Take the example that the first information comprises one bit. And if the bit value of the first information is 1, the first information indicates that the first terminal equipment silences uplink data transmission on the first time-frequency resource. And if the bit value of the first information is 0, the first information indicates the second terminal equipment to adjust the transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource.

As an optional implementation manner, the instructing, by the first information, the first terminal device to silence uplink data transmission on the first time-frequency resource may also be understood as: the first information indicates that the first indication information acts on the first terminal device. Similarly, when the first information indicates the second terminal device to perform uplink transmission on the time-frequency resource overlapped with the first time-frequency resource, adjusting the transmission power may also be understood as: the first information indicates that the first indication information acts on the second terminal device.

The network device or the protocol may be configured in advance at the first terminal device: and if the first indication information acts on the first terminal equipment, the first terminal equipment silences uplink data transmission on the first time-frequency resource. Optionally, if the first indication information does not act on the first terminal device, the first terminal device stops interpreting the other information except the first information in the first indication information. The network device or protocol may be configured in advance at the second terminal device: and if the first indication information acts on the second terminal equipment, the second terminal equipment adjusts the transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource. Optionally, if the first indication information does not act on the second terminal device, the second terminal device stops interpreting the other information except the first information in the first indication information. Similarly, the first information may be represented by a first information field in the first indication information, and the first information field may include one bit or a plurality of bits. Take the example that the first information comprises one bit. If the bit of the first information is 1, the first information indicates the first terminal equipment that the first indication information acts on the first terminal equipment. If the bit of the first information is 0, the first information indicates the second terminal device that the first indication information acts on the second terminal device.

The first information can also indicate that the first terminal equipment silences uplink data transmission on the first time-frequency resource, and the first indication information acts on the first terminal equipment; or, the first information is used to instruct the second terminal device to adjust the transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource, and the first instruction information acts on the second terminal device. For example, take the example that the first information includes 2 bits. And if the bit value of the first information is 01, the first information indicates that the first terminal equipment silences uplink data transmission on the first time-frequency resource, and indicates that the first indication information acts on the first terminal equipment. And if the bit value of the first information is 10, the first information indicates the second terminal equipment to adjust the transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource, and indicates the first indication information to act on the second terminal equipment.

Herein, in the entire application, the muting (stop or drop) uplink data transmission on the first time-frequency resource may refer to: and suspending the uplink data being transmitted on the first time-frequency resource, or canceling the uplink data to be transmitted on the first time-frequency resource.

Wherein, the time frequency resource overlapped with the first time frequency resource means: and the time frequency resources partially or completely overlap with the first time frequency resources. Throughout this application, overlapping may refer to partial or complete overlapping of time-frequency resources. The partial overlapping of the time-frequency resources may include the following three cases: firstly, the time domain resources are completely overlapped, and the frequency domain resources are partially overlapped. And secondly, the time domain resources are partially overlapped, and the frequency domain resources are completely overlapped. And thirdly, the time domain resources are partially overlapped, and the frequency domain resources are partially overlapped. Full overlap refers to full overlap in time domain resources and full overlap in frequency domain resources.

In this embodiment, the first terminal device and the second terminal device may be different types of terminal devices. The different types refer to different types of services transmitted by the terminal equipment. For example, the traffic type may be differentiated by the urgency/priority of the traffic, the transmission requirements of the traffic for bandwidth, latency, etc., or may be differentiated according to other rules. The transmission priorities of the different types of traffic and the amount of resources allocated differ. For example, the first terminal device is a terminal device for sending an eMBB transmission, and the second terminal device is a terminal device for sending a schedule-exempt URLLC transmission. For example, the first terminal device may be the terminal device 1 in fig. 1. The second terminal device may be terminal device 3 or terminal device 4 in fig. 1.

Alternatively, the first terminal device and the second terminal device may be the same type of terminal device. For example, the first terminal device is a terminal device for sending a non-scheduled low priority URLLC transmission, and the second terminal device is a terminal device for transmitting a non-scheduled URLLC transmission. For example, the first terminal device may be the terminal device 3 in fig. 1, and the second terminal device may be the terminal device 3 or the terminal device 4 in fig. 1. That is, the first terminal device and the second terminal device may be the same terminal device.

As an optional implementation, the first terminal device is a terminal device for sending an eMBB transmission. The network device sends the first indication information if the network device prepares or has scheduled a URLLC transmission on a time-frequency resource on which an eMBB transmission of the first terminal device is being sent or is about to be sent. The first indication information indicates a first time-frequency resource, and the first time-frequency resource is a time-frequency resource of the URLLC transmission based on the scheduling. Or the first time-frequency resource is a part of overlapping time-frequency resources of eMBB transmission of the first terminal equipment and time-frequency resources of URLLC transmission based on scheduling. And the first indication information comprises first information. The first information is used to instruct the first terminal device to silence uplink data transmission on the first time-frequency resource, or to instruct the first instruction information to act on the first terminal device.

The second terminal device is a terminal device for sending a schedulable URLLC transmission. The network device sends first indication information if the network device prepares or has scheduled an eMB B transmission on a scheduling-free time-frequency resource. The first indication information indicates a first time-frequency resource, which is a time-frequency resource for the eMBB transmission. Or the first time-frequency resource is a part of overlapping time-frequency resources transmitted by eMBB and scheduling-free time-frequency resources. And the first indication information comprises first information. The first information is used for instructing the second terminal device to adjust the transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource, or is used for instructing the first instruction information to act on the second terminal device.

Example 1: the terminal apparatus 1 is a terminal apparatus for transmitting scheduling-based eMBB transmission. Terminal device 2 is a terminal device for sending a URLLC transmission based on scheduling. Terminal device 3 and terminal device 4 are terminal devices for sending a schedule-free URLLC transmission. The network device sends the first indication information if the network device prepares or has scheduled a URLLC transmission of the terminal device 2 onto a time-frequency resource on which an eMBB transmission of the terminal device 1 is being sent or is about to be sent. The first indication information indicates a first time-frequency resource, which is a time-frequency resource of URLLC transmission of terminal device 2. Or, the first time-frequency resource is a portion where the time-frequency resource of the eMBB transmission of the terminal device 1 and the time-frequency resource of the URLLC transmission of the terminal device 2 overlap. The first indication information comprises first information. The bit value of the first information is 1, and is used to instruct the terminal device 1 to silence uplink data transmission on the first time-frequency resource, or to instruct the first instruction information to act on the terminal device 1.

After the terminal device 1 receives the first indication information, because the bit value of the first information is 1, the terminal device 1 determines, according to the first information, that the terminal device 1 silences uplink data transmission on the first time-frequency resource, or determines, according to the first information, that the first indication information acts on itself. Then, the terminal device 1 mutes the uplink data transmission on the first time-frequency resource.

After the terminal device 2 receives the first indication information, since the bit value of the first information is 1, the terminal device 2 determines that the first indication information does not act on itself according to the first information, and then the terminal device 2 stops reading other information except the first information in the first indication information.

After the terminal device 3 receives the first indication information, because the bit value of the first information is 1, the terminal device 3 determines, according to the first information, that the terminal device 3 does not adjust transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource, or determines, according to the first information, that the first indication information does not act on itself. Then, the terminal device 3 stops reading the other information except the first information in the first indication information to avoid the terminal device 3 performing an erroneous operation (e.g. adjusting the transmission power when the terminal device 3 performs uplink transmission on the time-frequency resource overlapping with the first time-frequency resource).

The operation of the terminal device 4 after receiving the first indication information is similar to that of the terminal device 3, and is not described in detail here.

In example 1, the bit value of the first information is 1. Alternatively, the bit value of the first information in example 1 may be 0.

Example 2: the terminal apparatus 1 is a terminal apparatus for transmitting scheduling-based eMBB transmission. Terminal device 3 and terminal device 4 are terminal devices for sending a schedule-free URLLC transmission. The network device sends the first indication information if the network device prepares or has scheduled the eMB B transmission of the terminal device 1 on a scheduling-free time-frequency resource. The first indication information indicates a first time-frequency resource, which is a time-frequency resource of eMBB transmission of the terminal device 1. Or, the first time-frequency resource is a portion where a time-frequency resource of the eMBB transmission of the terminal device 1 overlaps with a scheduling-free time-frequency resource. And the first indication information comprises first information. The bit value of the first information is 0, and is used to instruct the terminal device 3 and the terminal device 4 to adjust transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource, or to instruct the first instruction information to act on the terminal device 3 and the terminal device 4.

After the terminal device 1 receives the first indication information, because the bit value of the first information is 0, the terminal device 1 determines, according to the first information, that the terminal device 1 does not silence uplink data transmission on the first time-frequency resource, or determines, according to the first information, that the first indication information does not act on itself. Then, the terminal device 1 stops interpreting other information than the first information in the first indication information to avoid the terminal device 1 performing an erroneous operation (e.g., muting uplink data transmission on the first time-frequency resource).

After the terminal device 3 receives the first indication information, since the bit value of the first information is 0, the terminal device 3 determines, according to the first information, that the terminal device 3 adjusts transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource, or determines, according to the first information, that the first indication information acts on itself. The terminal device 3 determines a second time-frequency resource, which is used for sending uplink data. If the first time-frequency resource overlaps with the second time-frequency resource, the terminal device 3 transmits the uplink data on the second time-frequency resource with the first transmission power determined by the first power control parameter. The first power control parameter and the second power control parameter are different power control parameters configured for the higher layer signaling, including open loop power control parameters (e.g., a target signal-to-noise ratio (P0) of a transmission received by the network device, a path loss compensation factor (alpha), a path loss, etc.). Wherein the first transmission power is greater than a second transmission power determined by a second power control parameter. The second power control parameter may be a default parameter or a reference value, and the second transmission power may be a default transmission power. That is, if the first time-frequency resource overlaps with the second time-frequency resource, the terminal device 3 increases the transmission power on the second time-frequency resource to transmit the uplink data, so that the reliability of URLLC service transmission can be ensured to a certain extent. Of course, if the first time-frequency resource does not overlap with the second time-frequency resource, the terminal device 3 transmits the uplink data on the second time-frequency resource with the second transmission power. That is, when the first time-frequency resource is not overlapped with the second time-frequency resource, the terminal device 3 does not increase the transmission power in the second time-frequency resource to transmit the uplink data.

The operation of the terminal device 4 after receiving the first indication information is similar to that of the terminal device 3, and is not described herein again.

In example 2, the bit value of the first information is 0. Alternatively, the bit value of the first information in example 1 may be 1.

As an optional implementation, the first terminal device is a terminal device for transmitting a scheduling-free low priority URLLC service. The network device sends the first indication information if the network device prepares or has scheduled a URLLC transmission on a scheduling-free time-frequency resource of a low priority URLLC transmission of the first terminal device. The first indication information indicates a first time-frequency resource, and the first time-frequency resource is a time-frequency resource of the URLLC transmission based on the scheduling. Or the first time-frequency resource is a part of the scheduling-free time-frequency resource of the low-priority URLLC transmission of the first terminal device, which is overlapped with the time-frequency resource of the URLLC transmission based on the scheduling. And the first indication information comprises first information. The first information is used for indicating the first terminal equipment to silence the uplink data transmission on the first time-frequency resource.

The second terminal equipment is used for sending the URLLC service without scheduling. The network device sends first indication information if the network device prepares or has scheduled an eMB B transmission on a scheduling-free time-frequency resource. The first indication information indicates a first time-frequency resource, which is a time-frequency resource for the eMBB transmission. Or the first time-frequency resource is a part of overlapping time-frequency resources transmitted by eMBB and scheduling-free time-frequency resources. And the first indication information comprises first information. The first information is used for indicating the second terminal equipment to adjust the transmission power when the second terminal equipment carries out uplink transmission on the time-frequency resource overlapped with the first time-frequency resource.

Generally, the priority of the scheduled based URLLC transmission is higher. Therefore, when the scheduling-free time-frequency resources of the low-priority URLLC transmission overlap with the time-frequency resources of the URLLC transmission based on the scheduling, the first terminal device (the terminal device for transmitting the scheduling-free low-priority URLLC transmission) is instructed to silence the uplink data transmission on the time-frequency resources of the URLLC transmission based on the scheduling, so that the reliability of the URLLC transmission with high priority can be preferentially ensured.

Example 3: terminal device 2 is a terminal device for sending a URLLC transmission based on scheduling. Terminal device 3 is a terminal device for sending a schedule-free low priority URLLC transmission. Terminal device 4 is a terminal device for sending a high priority URLLC transmission free of scheduling. The network device sends the first indication information if the network device prepares or has scheduled a URLLC transmission of terminal device 2 onto a scheduling-free time-frequency resource of a low priority URLLC transmission of terminal device 3. The first indication information indicates a first time-frequency resource, which is a time-frequency resource of URLLC transmission of terminal device 2. Or, the first time-frequency resource is a portion where a scheduling-free time-frequency resource of the low-priority URLLC transmission of the terminal device 3 and a time-frequency resource of the URLLC transmission of the terminal device 2 overlap. And the first indication information comprises first information. The bit value of the first information is 1, and is used to instruct the terminal device 3 to silence uplink data transmission on the first time-frequency resource, or to instruct the first instruction information to act on the terminal device 3.

After the terminal device 3 receives the first indication information, because the bit value of the first information is 1, the terminal device 3 determines, according to the first information, that the terminal device 3 silences uplink data transmission on the first time-frequency resource, or determines, according to the first information, that the first indication information acts on the terminal device 3. Then, the terminal device 3 mutes the uplink data transmission on the first time-frequency resource. One embodiment of the terminal device 3 muting uplink data transmission on the first time-frequency resource is as follows: if the first time-frequency resource overlaps with a second time-frequency resource used by the terminal device 3 to send uplink data, the terminal device 3 mutes uplink data transmission on the second time-frequency resource. Of course, if the first time-frequency resource and the second time-frequency resource do not overlap, the terminal device 3 does not silence the uplink data transmission on the second time-frequency resource.

After the terminal device 4 receives the first indication information, because the bit value of the first information is 1, the terminal device 4 determines, according to the first information, that the terminal device 4 does not adjust transmission power when performing uplink transmission on a time-frequency resource overlapped with the first time-frequency resource, or determines, according to the first information, that the first indication information does not act on itself. Then, the terminal device 4 stops interpreting the other information than the first information in the first instruction information to avoid the terminal device 4 performing an erroneous operation.

In example 3, the bit value of the first information is 1. Alternatively, the bit value of the first information in example 1 may be 0.

Example 4: the terminal apparatus 1 is a terminal apparatus for transmitting scheduling-based eMBB transmission. Terminal device 3 and terminal device 4 are terminal devices for sending a schedule-free URLLC transmission. The network device sends the first indication information if the network device prepares or has scheduled the eMB B transmission of the terminal device 1 on a scheduling-free time-frequency resource. The first indication information indicates a first time-frequency resource, which is a time-frequency resource of eMBB transmission of the terminal device 1. Or, the first time-frequency resource is a portion where a time-frequency resource of the eMBB transmission of the terminal device 1 overlaps with a scheduling-free time-frequency resource. And the first indication information comprises first information. The bit value of the first information is 0, and is used to instruct the terminal device 3 and the terminal device 4 to adjust transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource, or to instruct the first instruction information to act on the terminal device 3 and the terminal device 4.

After the terminal device 1 receives the first indication information, since the bit value of the first information is 0, the terminal device 1 determines that the first indication information does not act on itself according to the first information, and then the terminal device 1 stops reading other information except the first information in the first indication information.

After the terminal device 3 receives the first indication information, since the bit value of the first information is 0, the terminal device 3 determines, according to the first information, to adjust transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource, or determines, according to the first information, that the first indication information acts on itself. Then, the terminal device 3 determines a second time-frequency resource, which is used for sending uplink data. If the first time-frequency resource overlaps with the second time-frequency resource, the terminal device 3 transmits uplink data on the second time-frequency resource with the first transmission power determined by the first power control parameter. For a specific implementation manner of the terminal device 3 sending the uplink data at the first transmission power determined by the first power control parameter on the second time-frequency resource, refer to the implementation manner of the terminal device 3 in the above example 2, which is not described herein again.

In example 3, the bit value of the first information is 0. Alternatively, the bit value of the first information in example 1 may be 1.

As an optional implementation manner, the first information is in a first information field of the first indication information, and the first indication information indicates the first time-frequency resource through a second information field. Wherein the first information field is different from the second information field. The first information field may comprise one or more bits. The second information field may comprise one or more bits. As shown in fig. 3, the first information field is different from the second information field. The embodiment of the present application does not limit the positions of the first information field and the second information field in the first indication information. For example, the first information field may precede the second information field, or the first information field may follow the second information field. That is to say, in the present application, an information field is additionally added to instruct the first terminal device to silence uplink data transmission on the first time-frequency resource, or instruct the second terminal device to adjust transmission power when performing uplink transmission on a time-frequency resource overlapped with the first time-frequency resource. Optionally, the first information field may include an information field that is a header bit or other bits of the first indication information. By setting two different information fields (i.e., a first information field and a second information field) in the first indication information, the terminal device can interpret only the first information in the first information field first. If the terminal device determines that the first indication information does not act on the terminal device according to the first information, the terminal device does not need to continuously read the first time-frequency resource in the second information domain, and therefore power consumption of the terminal device is saved.

As an optional implementation manner, the location of the first information field in the first indication information is configured by RRC signaling. For example, the position of the first bit of the first information field in the first indication information is configured by RRC signaling. That is, the network device configures, through RRC signaling, the position of the first bit of the first information field in the first indication information to the terminal devices (e.g., the first terminal device and the second terminal device). By configuring the position of the first information field in the first indication information by using RRC signaling, the terminal device can accurately determine the first information field, thereby reading the first information from the first information field.

As an alternative embodiment, the load size of the first indication information may also be configured by RRC signaling. That is, the network device may configure the load size of the first indication information to the terminal devices (e.g., the first terminal device and the second terminal device) through RRC signaling. The size of the payload of the first indication information is the number of bits of the first indication information. By configuring the load size of the first indication information by using RRC signaling, the terminal device can determine the search space where the first indication information is located and accurately detect all bits of the first indication information.

As an optional implementation, the cell on which the first indication information is applied is configured by RRC signaling. That is, the network device may configure the terminal device with the cell on which the first indication information acts through RRC signaling. For example, the first terminal device and the second terminal device belong to cell 1, and the third terminal device belongs to cell 2. And the network equipment configures the cell acted by the first indication information to the first terminal equipment to the third terminal equipment as a cell 1 through RRC signaling. Since the third terminal device belongs to the cell 2, the first indication information does not act on the cell 2, and therefore, the third terminal device does not need to detect the first indication information. The cell on which the first indication information acts is configured by using RRC signaling, so that terminal equipment under the cell on which the first indication information acts can detect the first indication information, and terminal equipment under the cell on which the first indication information does not act can not detect the first indication information.

202. And when the first terminal equipment determines that the first terminal equipment silences the uplink data transmission on the first time-frequency resource according to the first information, the first terminal equipment silences the uplink data transmission on the first time-frequency resource.

In the embodiment of the application, the first terminal device receives the first indication information. After the first terminal device receives the first indication information, when the first terminal device determines that the first terminal device silences the uplink data transmission on the first time-frequency resource according to the first information, the first terminal device silences the uplink data transmission on the first time-frequency resource.

As an optional implementation manner, when it is determined that the first terminal device does not silence uplink data transmission on the first time-frequency resource according to the first information, that the first indication information does not act on the first terminal device, the first terminal device may stop interpreting information other than the first information in the first indication information.

For example, the first terminal device may be the terminal device 1 in example 1 and example 2. Alternatively, the first terminal device may be the terminal device 3 in example 3 and example 4. For specific implementation of the first terminal device side, reference may be made to the descriptions in examples 1 to 4, which are not described herein again.

As an optional implementation manner, when it is determined that the first terminal device mutes the uplink data transmission on the first time-frequency resource according to the first information, the first terminal device stops the uplink data transmission on the first time-frequency resource after N orthogonal frequency division multiplexing OFDM symbols from the reception of the first indication information, and a subcarrier interval of the uplink data transmission is 30kHz (kilohertz). Wherein N is a positive number. By implementing this embodiment, uplink data transmission can be stopped on the first time-frequency resource in time.

And under the condition that the first indication information does not carry the first information, if the first indication information is used for the first terminal equipment to silence the uplink data transmission in the first time-frequency resource indicated by the first indication information. Then, the first terminal device stops uplink data transmission on the first time-frequency resource after receiving the first indication information and after N orthogonal frequency division multiplexing OFDM symbols, and the subcarrier spacing of the uplink data transmission is 30kHz (kilohertz). Wherein N is a positive number. Similarly, optionally, when the subcarrier interval for uplink data transmission is 30kHZ, N is not less than 2. Optionally, when the subcarrier interval for uplink data transmission is 30kHZ, N is N1+ N2. For the example of N, N1 and N2, when the subcarrier spacing for uplink data transmission is 30kHZ, the above example is referred to and will not be described herein. Optionally, the subcarrier spacing for the uplink data transmission may also be greater than or less than 30 kHz. For example, the subcarrier spacing for the uplink data transmission may be 15kHZ, 60kHZ, 120kHZ, or the like. When the subcarrier interval for uplink data transmission is 15kHZ, 60kHZ, or 120kHZ, the values of N, N1 and N2 may be referred to the above description, and are not described herein again.

203. The second terminal device determines a second time-frequency resource.

In the embodiment of the application, the second time-frequency resource is used for sending uplink data. The second terminal device needs to receive the first indication information. The second terminal device may determine the second time-frequency resource after receiving the first indication information or may determine the second time-frequency resource before receiving the first indication information.

Wherein, the execution sequence of step 202 and step 203 is not in sequence. Step 202 may be performed first, followed by step 203. Alternatively, step 203 may be performed first, and then step 202 may be performed. Alternatively, step 202 and step 203 may be performed simultaneously. Step 204 is performed after step 203.

204. And when the second terminal equipment determines that the second terminal equipment carries out uplink transmission on the time-frequency resource overlapped with the first time-frequency resource according to the first information, the transmission power is adjusted, and when the first time-frequency resource is overlapped with the second time-frequency resource, the second terminal equipment sends uplink data on the second time-frequency resource at the first transmission power determined by the first power control parameter.

Wherein the first transmission power is greater than the second transmission power determined by the second power control parameter. The second power control parameter may be a default parameter or a reference value, and the second transmission power may be a default transmission power.

As an optional implementation manner, when it is determined, according to the first information, that the terminal device does not adjust the transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource, it is indicated that the first indication information does not act on the second terminal device, and the second terminal device stops interpreting information other than the first information in the first indication information.

As an optional implementation manner, when it is determined that the terminal device performs uplink transmission on the time-frequency resource overlapped with the first time-frequency resource according to the first information, and the first time-frequency resource is completely not overlapped with the second time-frequency resource, the second terminal device sends uplink data on the second time-frequency resource at the second transmission power.

For example, the second terminal device may be the terminal device 3 or the terminal device 4 in examples 1 to 4. For specific implementation of the first terminal device side, reference may be made to the descriptions in examples 1 to 4, which are not described herein again.

As an optional implementation manner, a specific implementation manner in which the network device sends the first indication information is as follows: and sending the first indication information through a downlink control channel, wherein the downlink control channel is sent in the common search space. Accordingly, the first terminal device receives the first indication information through the downlink control channel. And the second terminal equipment receives the first indication information through the downlink control channel. By implementing this embodiment, the first indication information may act on a plurality of terminal devices, and both the first terminal device and the second terminal device may be able to receive the first indication information.

As an optional implementation manner, before the network device sends the first indication information, it may also send second indication information, where the second indication information is used to instruct the terminal device to detect the first indication information. Accordingly, before the first terminal device receives the first indication information, the second indication information can also be received. Before the second terminal equipment receives the first indication information, the second indication information can also be received. The first terminal device detects the first indication information after receiving the second indication information. Similarly, the second terminal device will detect the first indication information after receiving the second indication information. By implementing the embodiment, the terminal device detects the first indication information after receiving the second indication information, and does not need to detect the first indication information all the time, which is beneficial to saving the power consumption of the terminal device

Optionally, the second indication information may instruct the terminal device to detect the first indication information, or instruct the terminal device not to detect the first indication information. For example, the second indication information includes a bit, and when the value of the bit is 1, the terminal device is instructed to detect the first indication information. And when the value of the bit is 0, indicating the terminal equipment not to detect the first indication information. Before the network equipment sends the first indication information, sending second indication information, wherein the bit value of the second indication information is 1. And after receiving the second indication information, the first terminal equipment detects the first indication information. And after receiving the second indication information, the second terminal equipment detects the first indication information. On the contrary, if the value of the bit of the second indication information is 0. After the first terminal equipment receives the second indication information, the first indication information is not detected. And after the second terminal equipment receives the second indication information, the first indication information is not detected.

Optionally, the second indication information only indicates that the terminal device detects the first indication information, that is, the second indication information only indicates one condition, and does not indicate the two conditions. And if the terminal equipment does not receive the second indication information, the terminal equipment does not detect the first indication information.

In another possible implementation, the first indication information sent by the network device to the first terminal device and the second terminal device may not carry the first information. In order to indicate whether the first indication information of the first terminal equipment is sent to the first terminal equipment and indicate whether the first indication information of the second terminal equipment is sent to the second terminal equipment. The network device scrambles Downlink Control Information (DCI) carrying the first indication information. Each connected terminal device is configured with a Radio Network Temporary Identity (RNTI) specific to the terminal device. The network device scrambles the DCI with the RNTI dedicated to the terminal device. After the terminal equipment receives the DCI, if the DCI is sent to the terminal equipment, the terminal equipment can descramble and decode the DCI through the configured RNTI; otherwise, the terminal device cannot descramble and decode the DCI, because the RNTI scrambled by the network device is not the RNTI configured by the terminal device, the terminal device knows that the DCI is not addressed to itself. Currently, NR defines many RNTIs, including cell radio network temporary identifier (C-RNTI), temporary radio network temporary identifier (TC-RNTI), system information-radio network temporary identifier (SI-RNTI), paging radio network temporary identifier (P-RNTI), random access radio network temporary identifier (RA-RNTI), MCS-C-RNTI (UE unique identifier for indicating MCS table options for PDSCH and PUSCH channels). Of course, the RNTI scrambled for both types of indication information may be different from the existing RNTI.

In the method described by implementing fig. 2, the first indication information sent by the network device includes the first information. The first information may indicate that the first terminal device mutes uplink data transmission on the first time-frequency resource, or indicate whether to adjust transmission power when the second terminal device performs uplink transmission on a time-frequency resource overlapping with the first time-frequency resource. Thus, the first terminal device and the second terminal device can distinguish the function of the first indication information by the first information. It can be seen that by implementing the method described in fig. 2, the network device can indicate different functions through the indication information in one format, thereby simplifying system design, saving signaling overhead, improving communication efficiency, and avoiding the terminal device from performing misoperation.

Referring to fig. 4, fig. 4 is a flowchart illustrating another communication method according to an embodiment of the present disclosure. The execution subject of step 401 is a network device, or a chip in the network device. The execution subject of step 402 is the first terminal device or a chip in the first terminal device. The execution subjects of step 403 and step 404 are the second terminal device or the chip in the second terminal device. The following description will take as an example the network device, the first terminal device, and the second terminal device as execution subjects of the methods. As shown in fig. 4, the communication method includes steps 401 to 404, where:

401. the network device transmits the first indication information.

The first type information field of the first indication information is used for indicating a first time-frequency resource, and the second type information field of the first indication information is used for indicating a second time-frequency resource. The first type information field includes first information, and the first information is used for instructing the first terminal device to silence uplink data transmission on the first time-frequency resource. The second type information field includes second information, and the second information is used for instructing the second terminal device to adjust transmission power when performing uplink transmission on the time frequency resource overlapped with the second time frequency resource.

Wherein the first type information domain and the second type information domain are different. The first type of information domain is an information domain related to a first time-frequency resource, and the second type of information domain is an information domain related to a second time-frequency resource. The first type of information domain may comprise one or more information domains. The second type of information field may also include one or more information fields. Each information field of the first type of information field comprises one or more bits. Each information field of the second type of information field comprises one or more bits. The embodiment of the application does not limit the positions of the first type information domain and the second type information domain in the first indication information. For example, the first type of information field may precede the second type of information field, or the first type of information field may follow the second type of information field. The first type information field includes first information, and the second type information field includes second information. Wherein the first information may be represented by a bit or bits in the first type information field. The second information may be represented by a bit or bits in the second type information field. For example, fig. 5 exemplifies that the first information and the second information are both represented by one bit. As shown in fig. 5, the bit value of the first information is 1, and the bit value of the second information is 0. Alternatively, the bit value of the first information may be 0 and the bit value of the second information may be 1.

As an optional implementation, the first terminal device is a terminal device for sending an eMBB transmission, and the second terminal device is a terminal device for sending a schedulable URLLC transmission. The network device sends the first indication information if the network device prepares or has scheduled a URLLC transmission on a time-frequency resource on which an eMBB transmission of the first terminal device is being sent or is about to be sent, and schedules the eMBB transmission of the first terminal device on a scheduling-free time-frequency resource. And the first type information field of the first indication information indicates first time-frequency resources, and the first time-frequency resources are time-frequency resources of the URLLC transmission based on the scheduling. Or the first time-frequency resource is a part of the time-frequency resource of the eMBB transmission of the first terminal equipment and the time-frequency resource of the URLLC transmission based on the scheduling. The second type information field of the first indication information indicates a second time frequency resource, and the second time frequency resource is a time frequency resource of eMBB transmission of the first terminal equipment. Or the second time frequency resource is a part of overlapping time frequency resources of eMBB transmission of the first terminal equipment and scheduling-free time frequency resources.

Example 5: as shown in fig. 1, the terminal apparatus 1 is a terminal apparatus for transmitting scheduling-based eMBB transmission. Terminal device 2 is a terminal device for sending a URLLC transmission based on scheduling. Terminal device 3 and terminal device 4 are terminal devices for sending a schedule-free URLLC transmission. The network device sends the first indication information if the network device prepares or has scheduled a URLLC transmission of the terminal device 2 on a time-frequency resource on which an eMBB transmission of the terminal device 1 is being sent or is about to be sent, and prepares or has scheduled an eMBB transmission of the terminal device 1 on a scheduling-free time-frequency resource. The first type information field of the first indication information indicates a first time-frequency resource, which is a time-frequency resource of URLLC transmission of the terminal device 2. Or, the first time-frequency resource is a portion where the time-frequency resource of the eMBB transmission of the terminal device 1 and the time-frequency resource of the URLLC transmission of the terminal device 2 overlap. The second type information field of the first indication information indicates a second time frequency resource, and the second time frequency resource is a time frequency resource of the eMBB transmission of the terminal device 1. Or, the second time-frequency resource is a part where the time-frequency resource of the eMBB transmission of the terminal device 1 overlaps with the scheduling-free time-frequency resource. The first type information field includes first information, and a bit value of the first information is 1, which is used to instruct the terminal device 1 to silence uplink data transmission on the first time-frequency resource, or to instruct the first type information field to act on the terminal device 1. The second type information field includes second information, and a bit value of the second information is 0, which is used to instruct the terminal device 3 and the terminal device 4 to adjust transmission power when performing uplink transmission on a time frequency resource overlapped with the second time frequency resource, or to instruct the second type information field to act on the terminal device 3 and the terminal device 4.

After receiving the first indication information, the terminal device 1 reads the first information from the first type information field. Since the bit value of the first information is 1, the terminal device 1 determines, according to the first information, that the terminal device 1 silences uplink data transmission on the first time-frequency resource, or determines, according to the first information, that the first-class information field acts on the terminal device 1. Then, the terminal device 1 mutes the uplink data transmission on the first time-frequency resource. The terminal device 1 reads the second information from the second-type information domain, and because the bit value of the second information is 0, the terminal device 1 determines that the terminal device 1 does not perform silent uplink data transmission on the second time-frequency resource according to the second information, or determines that the second-type information domain does not act on the terminal device 1 according to the second information. Then the terminal device 1 does not continue to interpret other information than the second information in the second type information field.

After receiving the first indication information, the terminal device 2 reads the first information from the first type information field. Since the bit value of the first information is 1, the terminal device 2 determines that the first type information field does not act on the terminal device 2 according to the first information. Then the terminal device 2 does not continue to interpret other information than the first information in the first kind of information field. The terminal device 2 reads the second information from the second type information field, and the terminal device 2 determines that the second type information field does not act on the terminal device 2 according to the second information because the bit value of the second information is 0. Then the terminal device 2 does not continue to interpret other information than the second information in the second type of information field.

After receiving the first indication information, the terminal device 3 reads the first information from the first type information field. Because the bit value of the first information is 1, the terminal device 3 determines, according to the first information, that the terminal device 3 does not adjust the transmission power when performing uplink transmission on the time-frequency resource overlapped with the first time-frequency resource, or determines, according to the first information, that the first-class information field does not act on the terminal device 3. Then, the terminal device 3 stops interpreting the other information than the first information in the first-type information field to avoid the terminal device 3 performing an erroneous operation. The terminal device 3 reads the second information from the second information field, and because the bit value of the second information is 0, the terminal device 3 determines, according to the second information, that the terminal device 3 adjusts the transmission power when performing uplink transmission on the time frequency resource overlapped with the second time frequency resource, or determines, according to the second information, that the second information field does not act on the terminal device 3. Then, the terminal device 3 obtains a third time-frequency resource, where the third time-frequency resource is used for sending uplink data. And when the second time frequency resource is overlapped with the third time frequency resource, the second terminal equipment transmits the uplink data on the third time frequency resource by the first transmission power determined by the first power control parameter. Wherein the first transmission power is greater than a second transmission power determined by a second power control parameter. The second power control parameter may be a default parameter or a reference value, and the second transmission power may be a default transmission power. That is, if the second time-frequency resource overlaps with the third time-frequency resource, the terminal device 3 increases the transmission power on the third time-frequency resource to transmit the uplink data, so that the reliability of URLLC transmission can be ensured to a certain extent. Of course, if the second time-frequency resource does not overlap with the third time-frequency resource, the terminal device 3 sends the uplink data on the third time-frequency resource with the second transmission power, that is, when the second time-frequency resource does not overlap with the third time-frequency resource, the terminal device 3 sends the uplink data on the third time-frequency resource without increasing the transmission power.

The terminal device 4 is similar to the terminal device 3, and is not described in detail herein.

As an optional implementation, the first terminal device is a terminal device for transmitting a scheduling-exempt low-priority URLLC transmission, and the second terminal device is a terminal device for transmitting a scheduling-exempt URLLC transmission. The network device sends the first indication information if the network device prepares or has scheduled a URLLC transmission on a scheduling-free time-frequency resource of a low priority URLLC transmission of the first terminal device, and prepares or has scheduled an eMBB transmission on the scheduling-free time-frequency resource. And the first type information field of the first indication information indicates first time-frequency resources, and the first time-frequency resources are time-frequency resources of the URLLC transmission based on the scheduling. Or the first time-frequency resource is a part of the scheduling-free time-frequency resource of the low-priority URLLC transmission of the first terminal device, which is overlapped with the time-frequency resource of the URLLC transmission based on the scheduling. The second type information field of the first indication information indicates a second time frequency resource, and the second time frequency resource is the time frequency resource of eMBB transmission. Or the second time frequency resource is a part of the time frequency resource of eMBB transmission overlapped with the scheduling-free time frequency resource.

Example 6: the terminal apparatus 1 is a terminal apparatus for transmitting scheduling-based eMBB transmission. Terminal device 2 is a terminal device for transmitting a scheduling based URLLC transmission. Terminal 3 is a terminal for transmitting a low priority URLLC transmission free of scheduling, and terminal 4 is a terminal for transmitting a high priority URLLC transmission free of scheduling. The network device sends the first indication information if the network device prepares or has scheduled a URLLC transmission of the terminal device 2 on a scheduling free time-frequency resource of a low priority URLLC transmission of the terminal device 3 and prepares or has scheduled an eMBB transmission of the terminal device 1 on a scheduling free time-frequency resource. The first type information field of the first indication information indicates a first time-frequency resource, which is a time-frequency resource of URLLC transmission of the terminal device 2. Or, the first time-frequency resource is a portion where a scheduling-free time-frequency resource of the low-priority URLLC transmission of the terminal device 3 and a time-frequency resource of the URLLC transmission of the terminal device 2 overlap. The second type information field of the first indication information indicates a second time frequency resource, which is a time frequency resource for eMBB transmission of the terminal device 1. Or, the second time-frequency resource is a part where the time-frequency resource of the eMBB transmission of the terminal device 1 overlaps with the scheduling-free time-frequency resource. The first type information field includes first information, and a bit value of the first information is 1, which is used to instruct the terminal device 3 to silence uplink data transmission on the first time-frequency resource, or to instruct the first type information field to act on the terminal device 3. The second type information field includes second information, and a bit value of the second information is 0, which is used to instruct the terminal device 3 and the terminal device 4 to adjust transmission power when performing uplink transmission on a time frequency resource overlapped with the second time frequency resource, or to instruct the second type information field to act on the terminal device 3 and the terminal device 4.

After receiving the first indication information, the terminal device 1 reads the first information from the first type information field. Since the bit value of the first information is 1, the terminal device 1 determines that the first type information field does not act on the terminal device 1 according to the first information. Then the terminal device 1 does not continue to interpret other information than the first information in the first kind of information field. The terminal device 1 reads the second information from the second type information field, and the terminal device 1 determines that the second type information field does not act on the terminal device 1 according to the second information because the bit value of the second information is 0. Then the terminal device 1 does not continue to interpret other information than the second information in the second type information field.

Or, when the bit value of the first information is 1, the first information is used to instruct the terminal device 1 and the terminal device 3 to silence uplink data transmission on the first time-frequency resource. The terminal device 1 determines, according to the first information, that the terminal device 1 silences uplink data transmission on the first time-frequency resource, or determines that the first type information domain acts on itself. Then, the terminal device 1 mutes the uplink data transmission on the first time-frequency resource. The terminal device 1 reads the second information from the second type information field, and because the bit value of the second information is 0, the terminal device 1 determines that the uplink data transmission is not muted on the first time-frequency resource or the second type information field does not act on itself according to the second information. Then the terminal device 1 does not continue to interpret other information than the second information in the second type information field.

After receiving the first indication information, the terminal device 3 reads the first information from the first type information field. Since the bit value of the first information is 1, the terminal device 3 determines, according to the first information, that the terminal device 3 silences uplink data transmission on the first time-frequency resource, or determines, according to the first information, that the first type information field acts on the terminal device 3. Then, the terminal device 3 mutes the uplink data transmission on the first time-frequency resource. The terminal device 3 reads the second information from the second-type information field, and because the bit value of the second information is 0, the terminal device 3 determines, according to the second information, that the terminal device 3 adjusts the transmission power when performing uplink transmission on the time-frequency resource overlapped with the second time-frequency resource, or determines, according to the second information, that the second-type information field acts on the terminal device 3. Then, the terminal device 3 adjusts the transmission power when performing uplink transmission on the time frequency resource overlapped with the second time frequency resource. For the implementation manner of adjusting the transmission power when the terminal device 3 performs uplink transmission on the time frequency resource overlapped with the second time frequency resource, see the implementation manner of adjusting the transmission power when the terminal device 3 performs uplink transmission on the time frequency resource overlapped with the second time frequency resource in example 5, which is not described herein again.

The operation after the terminal device 4 receives the first indication information is similar to the operation of the terminal device 3 in example 5, and is not described in detail here.

As an optional implementation, the location of the first information in the first type information field is configured by radio resource control RRC signaling, and the location of the second information in the second type information field is configured by RRC signaling. Specifically, the position of the first bit of the first information in the first type information field is configured by radio resource control RRC signaling, and the position of the first bit of the second information in the second type information field is configured by RRC signaling. By configuring the position of the first information in the first type information field and the position of the second information in the second type information field by using RRC signaling, the terminal device can accurately read the first information and the second information.

As an optional implementation, the cell on which the first indication information is applied is configured by RRC signaling. That is, the network device may configure the terminal device with the cell on which the first indication information acts through RRC signaling. The cell on which the first indication information acts is configured by using RRC signaling, so that terminal equipment under the cell on which the first indication information acts can detect the first indication information, and terminal equipment under the cell on which the first indication information does not act can not detect the first indication information.

402. The first terminal device mutes the uplink data transmission on the first time-frequency resource.

And after receiving the first indication information, the first terminal equipment silences the uplink data transmission on the first time-frequency resource.

Here, the first terminal device may be the terminal device 1 in example 5. Alternatively, the first terminal device may be the terminal device 3 in example 6. For a specific implementation manner of the first terminal device side, reference may be made to the descriptions in examples 5 and 6 above, which are not described herein again.

Optionally, when the subcarrier spacing is 30kHz, N is not less than 2. Alternatively, when the subcarrier spacing is 30kHz, N is N1+ N2. When the subcarrier interval for uplink data transmission is 30kHz, the values of N, N1 and N2 can be referred to the related description in the embodiment corresponding to fig. 2, and are not described herein again.

Optionally, the subcarrier spacing for the uplink data transmission may also be greater than or less than 30 kHz. For example, the subcarrier spacing for the uplink data transmission may be 15kHZ, 60kHZ, 120kHZ, or the like. When the subcarrier interval for the uplink data transmission is 15kHZ, 60kHZ, or 120kHZ, the values of N, N1 and N2 may refer to the relevant description in the embodiment corresponding to fig. 2, and are not described herein again.

403. The second terminal device determines a third time-frequency resource.

Wherein, the third time frequency resource is used for sending uplink data. The second terminal device needs to receive the first indication information. The second terminal device may determine the third time-frequency resource after receiving the first indication information or may determine the third time-frequency resource before receiving the first indication information.

The execution sequence of step 402 and step 403 is not sequential. Step 402 may be performed first, followed by step 403. Alternatively, step 403 may be performed first, and then step 402 may be performed. Alternatively, step 402 and step 403 may be performed simultaneously. Step 404 is performed after step 403.

404. And when the second time frequency resource is overlapped with the third time frequency resource, the second terminal equipment transmits the uplink data on the third time frequency resource by the first transmission power determined by the first power control parameter.

Wherein the first transmission power is greater than a second transmission power determined by a second power control parameter. The second power control parameter may be a default parameter or a reference value, and the second transmission power may be a default transmission power.

In step 404, the second terminal device sends the uplink data on the third time-frequency resource with the first transmission power determined by the first power control parameter, which may be understood as that the second terminal device sends the uplink data on the third time-frequency resource with the transmission power increased. Optionally, when the second time-frequency resource and the third time-frequency resource are not overlapped at all, sending uplink data on the third time-frequency resource with the second transmission power. That is, when the second time-frequency resource and the third time-frequency resource are not overlapped at all, the transmission power is not increased on the third time-frequency resource to transmit the uplink data.

Here, the second terminal device may be the terminal device 3 or the terminal device 4 in examples 5 and 6. For a specific implementation manner of the second terminal device side, reference may be made to the descriptions in examples 5 and 6 above, which are not described herein again.

As an optional implementation manner, before the network device sends the first indication information, it may also send second indication information, where the second indication information is used to instruct the terminal device to detect the first indication information. Accordingly, before the first terminal device receives the first indication information, the second indication information can also be received. Before the second terminal equipment receives the first indication information, the second indication information can also be received. The first terminal device detects the first indication information after receiving the second indication information. Similarly, the second terminal device will detect the first indication information after receiving the second indication information. Optionally, if the terminal device does not receive the second indication information, the first indication information does not need to be detected. By implementing the embodiment, the first indication information is detected after the second indication information is received, and the first indication information does not need to be detected all the time, which is beneficial to saving the power consumption of the terminal equipment.

It can be seen that in the method described by implementing fig. 4, the first indication information includes a first type information field and a second type information field, the first type information field includes first information, and the second type information field includes second information. The first terminal device and the second terminal device can distinguish the functions of the first type information domain and the second type information domain through the first information and the second information. It can be seen that, by implementing the method described in fig. 4, the network device can indicate different functions through the indication information in one format, thereby simplifying system design, saving signaling overhead, improving communication efficiency, and avoiding the terminal device from performing misoperation.

Referring to fig. 6, fig. 6 is a flowchart illustrating another communication method according to an embodiment of the present disclosure. The execution subject of step 601 is a network device or a chip in the network device. The execution subjects of step 602 and step 603 are terminal equipment or chips in the terminal equipment. The following description will be made by taking a network device and a terminal device as an example of an execution subject of the method. As shown in fig. 6, the communication method includes steps 601 to 603, where:

601. the network device transmits the first indication information.

The first indication information is used for indicating a power control parameter adopted by each of M scheduling-free configurations, wherein M is an integer greater than 1. That is, the first indication information is used to indicate a power control parameter adopted by each of the two or more scheduling-free configurations.

Optionally, the power control parameter is a parameter for determining transmission power. For example, the power control parameter may be a power control command value or an open loop power control parameter, etc. The power control command value may be a closed loop power control procedure or the like. The open loop power control parameters may include P0 and alpha, among others. Where P0 is the target signal-to-noise ratio of the received signal at the network device and alpha is the path loss compensation factor.

The network device may pre-configure one or more schedule-free configurations for URLLC traffic for schedule-free transmission. For details included in the non-scheduling configuration, reference may be made to the foregoing description of the non-scheduling configuration, which is not described herein again.

Specifically, the network device sends the first indication information when the network device prepares or has scheduled an eMBB transmission on a scheduling-free time-frequency resource. For example, the network device is pre-configured with a total of 4 schedule-free configurations for URLLC transmissions. The terminal device 3 in fig. 1 uses the scheduling-free configuration 1 and the scheduling-free configuration 2 to perform URLLC transmission, and the terminal device 4 in fig. 1 uses the scheduling-free configuration 3 and the scheduling-free configuration 4 to perform URLLC transmission. As shown in fig. 7, if the network device prepares or has scheduled the eMBB transmission on the scheduling free time-frequency resources of scheduling free configuration 1, scheduling free configuration 2, and scheduling free configuration 3, the network device sends the first indication information.

Optionally, the M scheduling-free configurations are all scheduling-free configurations preset by the network device. For example, the first indication information is used to indicate a power control parameter adopted by the scheduling-exempt configuration 1, also used to indicate a power control parameter adopted by the scheduling-exempt configuration 2, also used to indicate a power control parameter adopted by the scheduling-exempt configuration 3, and also used to indicate a power control parameter adopted by the scheduling-exempt configuration 4. That is, even if the scheduling-free time-frequency resources of the scheduling-free configuration 4 do not overlap with the time-frequency resources of the eMBB transmission, the first indication information may indicate the power control parameters adopted by the scheduling-free configuration 4.

Or, the M scheduling-free configurations are configured as scheduling-free configurations in which the scheduling-free time-frequency resources overlap with time-frequency resources of the eMBB transmission. For example, the first indication information is used to indicate a power control parameter adopted by the scheduling-exempt configuration 1, also used to indicate a power control parameter adopted by the scheduling-exempt configuration 2, and also used to indicate a power control parameter adopted by the scheduling-exempt configuration 3. The first indication information does not indicate the power control parameter employed by the exempt scheduling configuration 4.

Optionally, each scheduling-free configuration has two (set) sets of power control parameters or more than two sets of power control parameters. For example, the schedule-free configuration 1 has a power control parameter 1 and a power control parameter 2. The schedule-free configuration 2 has a power control parameter 1 and a power control parameter 2. The scheduling-free configuration 3 and the scheduling-free configuration 4 are the same. Each schedule-free configuration may have the same or different power control parameters. For example, power control parameter 1 of non-scheduling configuration 1 may be the same as or different from power control parameter 1 of non-scheduling configuration 2. The power control parameter 2 of the scheduling-free configuration 1 may be the same as or different from the power control parameter 2 of the scheduling-free configuration 2. However, in the two sets of power control parameters of the same scheduling-free configuration, the transmission power determined by the power control parameter 1 is greater than the transmission power determined by the power control parameter 2. The power control parameter 2 may be a default control parameter or a reference value. The transmission power determined by the power control parameter 2 can be understood as a default transmission power, that is, in a default state, the terminal device performs uplink transmission by using the transmission power determined by the power control parameter 2.

Optionally, if each scheduling-exempt configuration has two sets of power control parameters, the transmission power determined by the power control parameter adopted by the first scheduling-exempt configuration indicated by the first indication information is greater than the default transmission power. The transmission power determined by the power control parameter adopted by the second scheduling-free configuration indicated by the first indication information is equal to the default transmission power. In the present application, the first non-scheduling configuration is a non-scheduling configuration in which non-scheduling time-frequency resources in the M non-scheduling configurations and time-frequency resources for eMBB transmission overlap. The second scheduling-free configuration is a scheduling-free configuration in which scheduling-free time-frequency resources in the M scheduling-free configurations do not overlap with time-frequency resources of eMBB transmission.

Optionally, if each scheduling-exempt configuration has more than two sets of power control parameters, the transmission power determined by the power control parameter adopted by the first scheduling-exempt configuration indicated by the first indication information is greater than the transmission power of the first scheduling-exempt configuration at the last transmission opportunity. The transmission power determined by the power control parameter adopted by the second scheduling-free configuration indicated by the first indication information is equal to the transmission power of the second scheduling-free configuration at the last transmission opportunity.

As an alternative, if the power control parameter is a power control command value, the power control command value adopted by the first scheduling-free configuration should be a non-negative value when the higher layer signaling configuration power is adjusted to the accumulation mode. A non-negative power control command value indicates that the transmission power determined from the power control command value is greater than the default transmission power or greater than the transmission power of the last transmission opportunity. When the higher layer signaling configuration power is adjusted to accumulation mode, the power control command value adopted by the second scheduling-free configuration should be 0. A power control command value of 0 indicates that the transmission power determined from the power control command value is equal to the transmission power of the last transmission opportunity.

As an optional implementation manner, if the power control parameter is a power control command value, when the higher layer signaling configuration power adjustment is in an absolute mode, the power control command value adopted by the first scheduling-free configuration is greater than the power adjustment value adopted by the last transmission opportunity. The power control command value being greater than the power adjustment value used at the previous transmission opportunity indicates that the transmission power determined from the power control command value is higher than the transmission power at the previous transmission opportunity. If the power control parameter is the power control command value, when the high-level signaling configuration power is adjusted to the absolute mode, the power control command value adopted by the second scheduling-free configuration is equal to the power adjustment value adopted by the last transmission opportunity. The power control command value equal to the power adjustment value used at the previous transmission opportunity indicates that the transmission power determined from the power control command value is equal to the transmission power at the previous transmission opportunity.

Two possible ways in which the first indication information indicates the power control parameter used by each of the M scheduling-free configurations are described below.

The first method is as follows: the first indication information indicates whether each of the M scheduling-free configurations increases the transmission power of uplink data transmission. When the terminal equipment transmits the uplink data on the scheduling-free configuration, the terminal equipment determines which group of power control parameters of the scheduling-free configuration is used to determine the transmission power of the uplink data transmission according to the first indication information. That is, in the first mode, the first indication information implicitly indicates the power control parameters adopted by each of the M scheduling-free configurations. In the first mode, each schedule-exempt configuration has two or more sets of power control parameters.

For example, if the power control parameters of the schedule-exempt configuration 1 include power control parameter 1 and power control parameter 2. The transmission power determined by power control parameter 1 is greater than the transmission power determined by power control parameter 2. The first indication information indicates that the transmission power of the uplink data transmission is increased on the scheduling-free configuration 1. Then, after receiving the first indication information, when transmitting the uplink data on the scheduling-free configuration 1, the terminal device 3 adjusts the transmission power of the uplink data according to the power control parameter 1 of the scheduling-free configuration 1, and transmits the uplink data using the adjusted transmission power.

As another example, if the power control parameters of the schedule-exempt configuration 1 include power control parameter 1, power control parameter 2, and power control parameter 3. The transmission power determined by the power control parameter 1 is greater than the transmission power determined by the power control parameter 2, and the transmission power determined by the power control parameter 2 is greater than the transmission power determined by the power control parameter 3. The first indication information indicates that the transmission power of the uplink data transmission is increased on the scheduling-free configuration 1. And the terminal equipment 3 uses the transmission power determined by the power control parameter 2 of the scheduling-free configuration 1 to perform uplink data transmission at the last transmission opportunity. Then, after receiving the first indication information, when transmitting the uplink data on the scheduling-free configuration 1, the terminal device 3 adjusts the transmission power of the uplink data according to the power control parameter 1 of the scheduling-free configuration 1, and transmits the uplink data using the adjusted transmission power.

In the first mode, the first indication information indicates that the scheduling-free time-frequency resources and the time-frequency resources for eMBB transmission have overlapped scheduling-free configuration to improve the transmission power for uplink data transmission. The first indication information indicates that the scheduling-free time frequency resources and the time frequency resources of the eMBB transmission do not have overlapped scheduling-free configuration and do not improve the transmission power of uplink data transmission.

The power control parameter employed by each of the M scheduling-free configurations may be indicated by a different bit field or bit. The power control parameter employed by each of the M scheduling-free configurations may be indicated by one or more bit fields or bits. The load size of the first indication information may be configured by RRC signaling. The load size of the first indication information is determined according to the number of M. For example, the power control parameter employed by a scheduling-free configuration is indicated by N bits, N being an integer greater than or equal to 1. Then, the load size of the first indication information may be M × N bits.

For example, taking N as 1 and M as 4, each schedule-free configuration has two sets of power control parameters. The first bit of the first indication information is used to indicate whether the scheduling-free configuration 1 increases the transmission power of the uplink data transmission. The second bit of the first indication information is used to indicate whether the scheduling-free configuration 2 increases the transmission power of the uplink data transmission. The third bit of the first indication information is used to indicate whether the scheduling-free configuration 3 increases the transmission power of the uplink data transmission. The fourth bit of the first indication information is used to indicate whether the scheduling-free configuration 4 increases the transmission power of the uplink data transmission. When the value of the bit is 1, it indicates that the transmission power of the uplink data transmission is increased. When the value of the bit is 0, it indicates that the transmission power of the uplink data transmission is not increased. As shown in fig. 7, since the network device prepares or has scheduled the eMBB transmission on the scheduling free time-frequency resources of scheduling free configuration 1, scheduling free configuration 2 and scheduling free configuration 3. Accordingly, a bit in the first indication information may be represented as 1110. That is, the first indication information indicates that the scheduling-free configuration 1, the scheduling-free configuration 2, and the scheduling-free configuration 3 all increase the transmission power of uplink data transmission, and the scheduling-free configuration 4 does not increase the transmission power of uplink data transmission. After receiving the first indication information, the terminal device 3 determines to increase the transmission power of the uplink data transmission on the non-scheduling configuration 1 according to the first bit of the first indication information, and determines to increase the transmission power of the uplink data transmission on the non-scheduling configuration 2 according to the second bit of the first indication information. Therefore, when transmitting the uplink data on the scheduling-free configuration 1, the terminal device 3 adjusts the transmission power of the uplink data according to the power control parameter 1 of the scheduling-free configuration 1, and transmits the uplink data using the adjusted transmission power. When the terminal device 3 transmits the uplink data on the scheduling-free configuration 2, the transmission power of the uplink data is adjusted according to the power control parameter 1 of the scheduling-free configuration 2, and the adjusted transmission power is used for transmitting the uplink data. After receiving the first indication information, the terminal device 4 determines to increase the transmission power of the uplink data transmission on the scheduling-free configuration 3 according to the third bit of the first indication information, and determines not to increase the transmission power of the uplink data transmission on the scheduling-free configuration 2 according to the fourth bit of the first indication information. Therefore, when the terminal device 4 transmits the uplink data on the scheduling-free configuration 3, the transmission power of the uplink data is adjusted according to the power control parameter 1 of the scheduling-free configuration 3, and the uplink data is transmitted using the adjusted transmission power. And when the terminal equipment 4 transmits the uplink data on the scheduling-free configuration 4, the uplink data is transmitted by adopting the transmission power determined by the power control parameter 2 of the scheduling-free configuration 4.

The second method comprises the following steps: the first indication information directly indicates the power control parameters adopted by each of the M scheduling-free configurations. That is, in the second mode, the first indication information explicitly indicates the power control parameter adopted by each of the M scheduling-free configurations. In mode two, each schedule-free configuration has two or more sets of power control parameters.

The power control parameter employed by each of the M scheduling-free configurations may be indicated by a different bit field or bit. The power control parameter employed by each of the M scheduling-free configurations may be indicated by one or more bit fields or bits. The load size of the first indication information may be configured by RRC signaling. The load size of the first indication information is determined according to the number of M. For example, the power control parameter employed by a scheduling-free configuration is indicated by N bits, N being an integer greater than or equal to 1. Then, the load size of the first indication information may be M × N bits. N is determined according to the number of sets of power control parameters each scheduling-free configuration has. For example, each schedule-free configuration has X sets of power control parameters. Then 2^NGreater than or equal to X.

For example, taking N as 2 and M as 4, each schedule-free configuration has three sets of power control parameters. The scheduling-free configuration 1 to the scheduling-free configuration 4 have a power control parameter 1, a power control parameter 2, and a power control parameter 3, respectively. Wherein, the transmission power determined by the power control parameter 1 is greater than the transmission power determined by the power control parameter 2, and the transmission power determined by the power control parameter 2 is greater than the transmission power determined by the power control parameter 3.

The 1 st bit and the 2 nd bit of the first indication information are used for indicating the power control parameter adopted by the scheduling-free configuration 1. The 3 rd bit and the 4 th bit of the first indication information are used for indicating the power control parameter adopted by the scheduling-free configuration 2. The 5th bit and the 6 th bit of the first indication information are used for indicating the power control parameter adopted by the scheduling-free configuration 3. The 7 th bit and the 8 th bit of the first indication information are used for indicating the power control parameter adopted by the scheduling-free configuration 4. As shown in table 1 below, when the bit corresponding to the scheduling-free configuration is 00, the power control parameter 1 adopted by the scheduling-free configuration is indicated. When the bit corresponding to the scheduling-free configuration is 01, the power control parameter 2 adopted by the scheduling-free configuration is indicated. When the bit corresponding to the scheduling-free configuration is 10, it indicates the power control parameter 3 adopted by the scheduling-free configuration.

TABLE 1

As shown in fig. 7, since the network device prepares or has scheduled the eMBB transmission on the scheduling free time-frequency resources of scheduling free configuration 1, scheduling free configuration 2 and scheduling free configuration 3. And the terminal equipment 3 uses the transmission power determined by the power control parameter 2 of the scheduling-free configuration 1 and the scheduling-free configuration 2 to perform uplink data transmission at the last transmission opportunity. And the terminal equipment 4 uses the transmission power determined by the power control parameter 2 of the scheduling-free configuration 3 and the scheduling-free configuration 4 to carry out uplink data transmission at the last transmission opportunity. Accordingly, the bits in the first indication information may be represented as 00000001. That is, the first indication information indicates that the scheduling-free configuration 1, the scheduling-free configuration 2, and the scheduling-free configuration 3 all employ the power control parameter 1, and the scheduling-free configuration 4 employs the power control parameter 2. After receiving the first indication information, the terminal device 3 determines to adopt the power control parameter 1 in the non-scheduling configuration 1 according to the 1 st bit and the 2 nd bit of the first indication information, and determines to adopt the power control parameter 1 in the non-scheduling configuration 2 according to the 3 rd bit and the 4 th bit of the first indication information. Therefore, when transmitting the uplink data on the scheduling-free configuration 1, the terminal device 3 adjusts the transmission power of the uplink data according to the power control parameter 1 of the scheduling-free configuration 1, and transmits the uplink data using the adjusted transmission power. When the terminal device 3 transmits the uplink data on the scheduling-free configuration 2, the transmission power of the uplink data is adjusted according to the power control parameter 1 of the scheduling-free configuration 2, and the adjusted transmission power is used for transmitting the uplink data. After receiving the first indication information, the terminal device 4 determines to adopt the power control parameter 1 in the non-scheduling configuration 3 according to the 5th bit and the 6 th bit of the first indication information, and determines to adopt the power control parameter 2 in the non-scheduling configuration 2 according to the 7 th bit and the 8 th bit of the first indication information. Therefore, when the terminal device 4 transmits the uplink data on the scheduling-free configuration 3, the transmission power of the uplink data is adjusted according to the power control parameter 1 of the scheduling-free configuration 3, and the uplink data is transmitted using the adjusted transmission power. And when the terminal equipment 4 transmits the uplink data on the scheduling-free configuration 4, the uplink data is transmitted by adopting the transmission power determined by the power control parameter 2 of the scheduling-free configuration 4.

As an optional implementation manner, the first indication information may further indicate a time-frequency resource of the eMBB transmission, or indicate a portion where the time-frequency resource of the eMBB transmission overlaps with the scheduling-free time-frequency resource. Thus, the terminal equipment can adjust the transmission power only in the time-frequency resource indicated by the first indication information.

As an alternative embodiment, the load size of the first indication information may be configured by RRC signaling. By configuring the load size of the first indication information using RRC signaling, the terminal device can accurately detect all bits of the first indication information.

602. And when the uplink data is transmitted in at least one scheduling-free configuration in the M scheduling-free configurations, the terminal equipment adjusts the transmission power of the uplink data according to the power control parameter indicated by the first indication information.

In this embodiment of the application, after the terminal device receives the first indication information, when at least one scheduling-free configuration of the M scheduling-free configurations transmits uplink data, the terminal device adjusts the transmission power of the uplink data according to the power control parameter indicated by the first indication information.

603. And the terminal equipment transmits the uplink data by using the adjusted transmission power.

After the terminal device transmits the uplink data by using the adjusted transmission power, correspondingly, the grid device receives the uplink data of the transmission power adjusted on at least one scheduling-free configuration resource in the M scheduling-free configurations according to the power control parameter.

The terminal devices may be the terminal device 3 and the terminal device 4 in the above examples of the first mode and the second mode. For a specific implementation manner of the terminal device side, reference may be made to implementation manners of the terminal device 3 and the terminal device 4 in the above examples of the first and second manners, which is not described herein again.

As an optional implementation manner, a specific implementation manner in which the network device sends the first indication information is as follows: and sending the first indication information through a downlink control channel, wherein the downlink control channel is sent in the common search space. Accordingly, the terminal device receives the first indication information through the downlink control channel. By implementing this embodiment, the first indication information can act on a plurality of terminal devices, and the terminal devices can all receive the first indication information.

As an optional implementation manner, before the network device sends the first indication information, it may also send second indication information, where the second indication information is used to instruct the terminal device to detect the first indication information. Accordingly, before the terminal device receives the first indication information, the terminal device may also receive the second indication information. The terminal device detects the first indication information after receiving the second indication information. Optionally, if the terminal device does not receive the second indication information, the first indication information does not need to be detected. By implementing the embodiment, the first indication information is detected after the second indication information is received, and the first indication information does not need to be detected all the time, which is beneficial to saving the power consumption of the terminal equipment.

It can be seen that in the method described by implementing fig. 6, the power control parameters adopted by multiple scheduling-exempt configurations can be indicated by one indication information. The method is beneficial to simplifying signaling, improving communication efficiency and reducing the overhead of control information.

The embodiments of the present invention may perform functional unit division on the device according to the above method examples, for example, each functional unit may be divided corresponding to each function, or two or more functions may be integrated into one unit. The integrated unit can be realized in a form of hardware, and can also be realized in a form of a software functional unit. It should be noted that the division of the unit in the embodiment of the present invention is schematic, and is only a logic function division, and there may be another division manner in actual implementation.

Referring to fig. 8, fig. 8 is a schematic structural diagram of a communication device according to an embodiment of the present application. The communication apparatus shown in fig. 8 may be used to perform part or all of the functions of the first terminal device in the method embodiment described in fig. 2 above. The communication apparatus shown in fig. 8 may include a receiving unit 801 and a processing unit 802. Wherein:

a receiving unit 801, configured to receive first indication information, where the first indication information is used to indicate a first time-frequency resource, and the first indication information includes first information, and the first information is used to indicate whether a communication apparatus mutes uplink data transmission on the first time-frequency resource; a processing unit 802, configured to silence uplink data transmission on the first time-frequency resource when it is determined that the communication apparatus silences uplink data transmission on the first time-frequency resource according to the first information.

As an optional implementation manner, the processing unit 802 is further configured to stop interpreting information other than the first information in the first indication information when it is determined that the communication apparatus does not silence the uplink data transmission on the first time-frequency resource according to the first information.

As an optional implementation manner, when it is determined that the communication apparatus mutes the uplink data transmission on the first time-frequency resource according to the first information, the uplink data transmission is stopped on the first time-frequency resource after 4.5 orthogonal frequency division multiplexing OFDM symbols are received from the reception of the first indication information, and the subcarrier interval of the uplink data transmission is 30 kHz.

As an optional implementation manner, the receiving unit 801 is further configured to receive second indication information, where the second indication information is used to instruct the communication device to detect the first indication information.

As an optional implementation manner, the manner of receiving the first indication information by the receiving unit 801 is specifically: and receiving the first indication information through a downlink control channel, wherein the downlink control channel is transmitted in the common search space.
