Description

Method and apparatus for wireless communication

Technical Field

Embodiments of the present application relate to the field of communications, and more particularly, to methods and apparatus for wireless communications.

Background

Currently, a 5G new air interface (NR) system introduces two services, low latency high reliability communications (Ultra-Reliable and Low Latency Communication, URLLC) and enhanced mobile Ultra-wideband (Enhance Mobile Broadband, eMBB). Wherein URLLC is characterized by ultra-high reliability (e.g., 99.999%) transmissions within extreme delays (e.g., 1 ms), eMBB is characterized by being delay insensitive, but the number of transmissions can be significant. For scenarios where URLLC and eMBB coexist, in order to achieve URLLC immediate transmission, the resources of URLLC and the resources of eMBB may collide, i.e. URLLC occupies the resources already allocated to eMBB.

Accordingly, there is an urgent need in the art for a wireless communication method capable of reducing multi-user interference.

Detailed Description

The following description of the technical solutions according to the embodiments of the present application will be given with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Fig. 1 is a schematic diagram of an application scenario according to an embodiment of the present application.

As shown in fig. 1, communication system 100 may include a terminal device 110 and a network device 120. Network device 120 may communicate with terminal device 110 over the air interface. Multi-service transmission is supported between terminal device 110 and network device 120.

It should be understood that embodiments of the present application are illustrated by way of example only with respect to communication system 100, and embodiments of the present application are not limited thereto. That is, the technical solution of the embodiment of the present application may be applied to various communication systems, for example: long term evolution (Long Term Evolution, LTE) system, LTE time division duplex (Time Division Duplex, TDD), universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS), 5G communication system (also referred to as New Radio (NR) communication system), or future communication system, etc.

In the communication system 100 shown in fig. 1, the network device 120 may be an access network device in communication with the terminal device 110. The access network device may provide communication coverage for a particular geographic area and may communicate with terminal devices 110 (e.g., UEs) located within the coverage area.

Alternatively, the network device 120 may be an evolved base station (Evolutional Node B, eNB or eNodeB) in a long term evolution (Long Term Evolution, LTE) system, or a next generation radio access network (Next Generation Radio Access Network, NG RAN) device, or a base station (gNB) in an NR system, or a radio controller in a cloud radio access network (Cloud Radio Access Network, CRAN), or the network device 120 may be a relay station, an access point, a vehicle device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved public land mobile network (Public Land Mobile Network, PLMN), or the like.

Alternatively, the terminal device 110 may be any terminal device including, but not limited to: a terminal device that employs a wired or wireless connection with network device 120 or other terminal devices. A terminal device may refer to an access terminal, user Equipment (UE), subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or User Equipment. An access terminal may be a cellular telephone, a cordless telephone, a session initiation protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a personal digital assistant (Personal Digital Assistant, PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network or a terminal device in a future evolution network, etc.

Alternatively, device-to-Device (D2D) communication may be performed between the terminal devices 110.

The wireless communication system 100 may further comprise a core network device 130 in communication with the base station, which core network device 130 may be a 5G core,5gc device, e.g. an access and mobility management function (Access and Mobility Management Function, AMF), further e.g. an authentication server function (Authentication Server Function, AUSF), further e.g. a user plane function (User Plane Function, UPF), further e.g. a session management function (Session Management Function, SMF). Optionally, the core network device 130 may also be a packet core evolution (Evolved Packet Core, EPC) device of the LTE network, for example a session management function+a data gateway (Session Management Function + Core Packet Gateway, smf+pgw-C) device of the core network. It should be appreciated that SMF+PGW-C may perform the functions performed by both SMF and PGW-C. In the network evolution process, the core network device may also call other names, or form new network entities by dividing the functions of the core network, which is not limited in this embodiment of the present application.

In a specific example, communication may be implemented by establishing a connection between functional units in the communication system 100 through a next generation Network (NG) interface.

For example, the terminal device establishes an air interface connection with the access network device through an NR interface, and is used for transmitting user plane data and control plane signaling; the terminal equipment can establish control plane signaling connection with AMF through NG interface 1 (N1 for short); an access network device, such as a next generation radio access base station (gNB), can establish a user plane data connection with a UPF through an NG interface 3 (N3 for short); the access network equipment can establish control plane signaling connection with AMF through NG interface 2 (N2 for short); the UPF can establish control plane signaling connection with the SMF through an NG interface 4 (N4 for short); the UPF can interact user plane data with the data network through an NG interface 6 (N6 for short); the AMF may establish a control plane signaling connection with the SMF through NG interface 11 (N11 for short); the SMF may establish a control plane signaling connection with the PCF via NG interface 7 (N7 for short). It should be noted that the portion shown in fig. 2 is only an exemplary architecture, and the network architecture may further include other functional units or functional entities besides the functional units shown in fig. 1, for example: the core network device may further include other functional units such as a unified data management function (unified data management, UDM), which is not specifically limited in the embodiment of the present application.

Fig. 1 exemplarily illustrates one base station, one core network device, and two terminal devices, alternatively, the wireless communication system 100 may include a plurality of base station devices and each base station may include other number of terminal devices within a coverage area, which is not limited by the embodiment of the present application.

It should be understood that devices having communication functions in the network/system according to the embodiments of the present application may be referred to as communication devices. Taking the communication system 100 shown in fig. 1 as an example, the communication device may include a network device 120 and a terminal device 110 with communication functions, where the network device 120 and the terminal device 110 may be the devices described above, and are not described herein again; the communication device may also include other devices in the communication system 100, such as a network controller, a mobility management entity, and other network entities, which are not limited in this embodiment of the present application.

It should be understood that the terms "system" and "network" are used interchangeably herein. The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

Taking the communication system 100 as a 5G system as an example, main application scenarios of 5G include: enhanced mobile Ultra-wideband (Enhance Mobile Broadband, emmbb), low latency high reliability communications (Ultra-Reliable and Low Latency Communication, URLLC), large scale machine type communications (massive machine type of communication, mctc). Among them, the ebb aims at users getting multimedia contents, services and data, and its demand is growing very rapidly. Since the eMBB may be deployed in a different scenario. For example, indoors, urban areas, rural areas, etc., the capability and demand of which are also quite different, so that detailed analysis can be combined with specific deployment scenarios cannot be generalized. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical characteristics of mctc include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

Further, for scenarios where URLLC and eMBB coexist, to achieve URLLC immediate transmission, resource conflict may occur for URLLC and eMBB, i.e. URLLC occupies resources already allocated to eMBB. In one implementation, interference to URLLC is reduced by stopping the eMBB transmission. In another implementation, the received SINR of URLLC can be guaranteed to meet demodulation requirements by increasing URLLC transmit power, thereby even in the presence of eMBB interference.

However, the method of stopping the ebb transmission can completely eliminate interference, and frequent detection of PDCCH by the ebb is required, which increases complexity of the ebb terminal. The method for improving the URLLC transmission power needs to ensure that the URLLC pilot frequency is orthogonal to the eMBB user pilot frequency, and the power-limited user cannot continue to improve the power. The two methods have advantages and disadvantages and are applicable to different scenes.

The application provides a method for wireless communication, which can adapt to the scene of arbitrary combination of different types of terminals by unifying power lifting for URLLC terminals and stop transmission for eMBB terminals under one mechanism frame, avoid system complexity caused by coexistence of multiple mechanisms and increase complexity and standard complexity.

Fig. 2 is a schematic block diagram of a method 200 for wireless communication in accordance with an embodiment of the present application. The method 200 may be performed by a terminal device or a network device. The terminal device shown in fig. 2 may be a terminal device as shown in fig. 1, and the network device shown in fig. 2 may be an access network device as shown in fig. 1.

As shown in fig. 2, the method 200 may include:

s210, the network equipment sends first indication information to the terminal equipment.

Wherein the first indication information is used for indicating at least one of the following information:

The transmitting power is not adjusted;

a power increment of the transmit power;

a power reduction of the transmit power; and

and stopping transmission.

Specifically, after receiving a transmission request of target data from a terminal, the network device determines resources for transmitting the data. Optionally, the transmission resource may be according to information such as a data amount of the data, a reliability requirement and/or a delay requirement of the service corresponding to the data (the information may be obtained by the transmission request). Optionally, the transmission resource collides with the transmission resource of the allocated first data. For example, the target data is data of URLLC service, and the first data is data of eMBB service.

It is to be understood that the terminology used in the embodiments of the application is for the purpose of describing particular embodiments only, and is not intended to be limiting.

For example, the transmission stopping may also be referred to as stopping transmitting data or adjusting the transmission power to a first preset threshold or adjusting the transmission power to be lower than a second preset threshold.

It should also be understood that the type of the target data is not particularly limited in the embodiment of the present application. For example, the target data may be uplink data (data transmitted to the network device) or sidestream data (data transmitted to other terminal devices). For another example, the target data may include at least one of the following channels: physical uplink control channel (Physical Uplink Control Channel, PUCCH), physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), physical random access channel (Physical Random Access Channel, PRACH), and sounding reference signal (Sounding Reference Signal, SRS).

Since the scheduling decisions and scheduling information transmissions of both URLLC and eMBB are unsynchronized and URLLC is delay sensitive, i.e. there is not enough time to wait for idle resource transmissions, resource collision of URLLC and eMBB is unavoidable, as shown in fig. 3, where UE3 transmitting eMBB and UE2 transmitting URLLC occur.

At this time, the network device may send the first indication information to the terminal device, so as to eliminate or weaken the impact of the ebb interference, and ensure the reliability of the URLLC. The first indication information may be used to indicate uplink data power boost or stop uplink data transmission.

As shown in fig. 3, assuming that a User Equipment (UE) 3 transmitting an eMBB collides with a UE2 transmitting a URLLC, when the network device determines that the UE3 can stop transmitting, the first indication information UE3 is sent to stop transmitting. Since the interference from UE3 is completely eliminated, no additional enhancements are needed for UE2 transmission. When the network device determines that the UE3 cannot stop transmission (and not stop transmission), the reliability of the URLLC can only be guaranteed by increasing the transmission power of the URLLC, the first indication information is sent to instruct the UE2 to increase the power. Further, the network device may predict that the interference energy of the UE3 is 3dB according to the power control policy of the UE3, and instruct the UE2 to boost the power by 3dB through the first indication information, so that the SINR of the UE2 remains unchanged, and the reliability thereof meets the expected target.

The network device may determine an interference coordination policy according to factors such as whether the two conflicting users can stop transmission and/or whether the two conflicting users can boost power, so as to generate the first indication information, and send the first indication information to the terminal device.

S220, the terminal equipment sends or stops sending target data according to the first information and the first indication information.

And after receiving the first indication information, the terminal equipment sends or stops sending the target data according to the first information and the physical meaning of the first indication information.

The physical meaning of the first indication information will be described in detail.

Table 1 comparison of index and physical meaning of first indication information

Index of first indication information	Meaning of physics
		000	Stopping transmission
001	Power boost 3dB
		010	Power boost 5dB
011	Power boost 6dB
		100	Power boost 7dB
101	Power boost 8dB
		110	Power boost 9dB
111	Invalidation of

As shown in table 1, the first indication information may indicate 8 states through 3 bits, where each state corresponds to a different physical meaning.

Taking the case where the UE2 and the UE 3 shown in fig. 3 collide with each other as an example, when the network device determines that the UE 3 can stop transmitting, first indication information, for example, 000 is sent to instruct the UE 3 to stop transmitting. When the network device determines that the UE 3 cannot stop transmission (and not stop transmission), the reliability of the URLLC can only be guaranteed by increasing the transmission power of the URLLC, and determines that the UE2 needs to be increased by 3dB to meet the reliability expectation, first indication information, such as 001, is sent to instruct the UE2 to increase the power by 3dB.

Since the stop transmitting data is for the emmbb traffic, the power boost is for the URLLC traffic.

Therefore, the terminal device can send or stop sending the target data according to the first information and the first indication information; wherein the first information includes at least one of the following information:

the method comprises the steps of determining a service type of target data, a service priority of the target data, a service type supported by the terminal equipment, a format of first Downlink Control Information (DCI) for scheduling the target data, CORESET) for scheduling a first DCI of the target data, a search space for scheduling the first DCI of the target data, a scrambling mode for scheduling the first DCI of the target data and a scrambling mode for carrying second DCI of the first indication information.

Wherein, the format of the downlink control information DCI for scheduling the target data includes, but is not limited to, a DCI format for downlink PDSCH or a DCI format for PDCCH. For example, DCI formats for downlink PDSCH include, but are not limited to: DCI1, DCI1A, DCI1B, DCI1C, DCI1D, DCI2, DCI2A, and DCI2B.

Scrambling means of the DCI include, but are not limited to:

System message radio network temporary identity (System Information Network Temporary Identifier, SI-RNTI), paging radio network temporary identity (Paging Radio Network Temporary Identifier, P-RNTI), random Access radio network temporary identity (Radom Access RNTI, RA-RNTI), temporary cell radio network temporary identity (temporary Cell Radio Network Temporary Identifier, TC-RNTI), cell radio network temporary identity (Cell Radio Network Temporary Identifier, C-RNTI), semi-persistent scheduling radio network temporary identity (Semi-Persistent Scheduling Network Temporary Identifier, SPS-RNTI), terrestrial radio Access network temporary identity (UMTS Terrestrial Radio Access Network RNTI, u-RNTI).

In some embodiments of the present application, when the first information meets a first condition and the first indication information is specifically used for indicating that the transmission power is not adjusted, the terminal device sends the target data according to a first power, where the first power may be the transmission power before the terminal device receives the first indication information or when the terminal device receives the first indication information. For example, the first power is a transmit power determined by the terminal device using an open loop power control mechanism and/or a closed loop power control mechanism.

Wherein the first condition includes at least one of: the service type of the target data is the service type of a first service, the service priority of the target data is higher than a preset priority, and the service type supported by the terminal device includes (for example, only includes) the first service, the format of the first DCI is a first format, CORESET where the first DCI is located is the first CORESET, the search space where the first DCI is located is a first search space, and the scrambling mode of the first DCI is a first scrambling mode and a second scrambling mode of the second DCI.

As shown in fig. 3 and table 1, assuming that the first indication information sent by the network device is 111 for indicating invalidation (i.e. not adjusting power), since the traffic type transmitted by the UE2 is URLLC traffic, the first indication information received by the UE2 (i.e. invalidation) is valid for the traffic type, and therefore, the UE3 sends URLLC data according to the first power.

In other embodiments of the present application, when the first information satisfies the first condition and the first indication information is specifically used to indicate a power increment of a transmission power, the terminal device transmits the target data according to a second power, where the second power is equal to a sum of the first power and the power increment.

As shown in fig. 3 and table 1, when it is assumed that the first indication information sent by the network device is 001 for indicating the power boost of 3dB, since the service type transmitted by the UE2 is the ullc service, the first indication information (i.e. the power boost of 3 dB) received by the UE2 is valid for the first indication information, so that the UE3 sends ullc data according to the boosted transmission power.

It should be understood that the embodiment of the present application does not specifically limit the first format and the first scrambling method.

For example, the first format may be a DCI format including, but not limited to, a DCI format for a downlink PDSCH or a DCI format for a PDCCH. For example, DCI formats for downlink PDSCH include, but are not limited to: DCI1, DCI1A, DCI1B, DCI1C, DCI1D, DCI2, DCI2A, and DCI2B.

The first scrambling means includes, but is not limited to, SI-RNTI, P-RNTI, RA-RNTI, TC-RNTI, C-RNTI, SPS-RNTI, u-RNTI.

In other embodiments of the present application, when the first information satisfies the second condition and the first indication information is specifically used to indicate a power reduction amount of the transmission power, the terminal device transmits the target data according to a third power, where the third power is equal to a difference obtained by subtracting the power reduction amount from the first power.

Wherein the second condition includes at least one of: the service type of the target data is the service type of a second service, the service priority of the target data is lower than a preset priority, the service type supported by the terminal device comprises (only) the second service, the CORESET where a first DCI is located is a second CORESET, the search space where the first DCI is located is a second search space, the format of the first DCI is a second format, the scrambling mode of the first DCI is a third scrambling mode and the scrambling mode of the second DCI is a fourth scrambling mode, wherein the first CORESET and the second CORESET are different CORESETs, the first search space and the second search space are different search spaces, the priority of the first service is higher than the grade of the second service, the first format and the second format are different, the first scrambling mode and the third scrambling mode are different, and the second scrambling mode and the fourth scrambling mode are different.

In connection with fig. 3, when it is assumed that the first indication information sent by the network device is an index for indicating a power drop by x dB, since the service type transmitted by the UE3 is an eMBB service, the first indication information (i.e., the power drop by x dB) received by the UE3 is valid for the same, so that the UE3 sends the target data according to the dropped transmission power.

In other embodiments of the present application, the terminal device stops sending the target data when the first information satisfies the second condition and the first indication information is specifically used to indicate to stop transmission.

In connection with fig. 3, it is assumed that the first indication information sent by the network device is 000 for indicating to stop transmission, and since the traffic type transmitted by the UE3 is eMBB traffic, the first indication information received by the UE3 (i.e., stopping transmission) is valid for it, the UE3 performs an action of stopping transmission.

It should be understood that the embodiment of the present application only needs to distinguish the first format from the second format, and is not limited to the specific format of the first format and the second format. Similarly, the embodiment of the present application only needs to distinguish the first scrambling mode from the second scrambling mode, and is not limited to the specific form of the first scrambling mode and the second scrambling mode. For example, the second format may be a DCI format other than the first format among all formats of the DCI. Similarly, the second scrambling method may be a scrambling method other than the first scrambling method among all scrambling methods of the DCI.

It should be appreciated that the first service may be a URLLC service and the second service may be an eMBB service. But the present application is not limited thereto.

It should also be understood that the embodiment of the present application does not limit the manner of acquiring the first information.

For example, the first information may be information stored in the terminal device in advance (for example, the type of the terminal device).

For another example, the first information may be information indicated to the terminal device by the network device. For example, the terminal device receives second indication information; the second indication information is used for indicating the service type of the target data and/or the service priority of the target data. In one implementation manner, the second indication information indicates the service type of the target data and/or the service priority of the target data through a format or scrambling manner of downlink control information DCI for scheduling the target data.

It should also be understood that the service types supported by the terminal device may also be understood as the types of the terminal device. For example, the types of the terminal devices may refer to URLLC terminal devices and eMBB terminal devices, i.e. terminal devices supporting only one of the services.

In the embodiment of the present application, the first indication information includes a plurality of physical meanings, and different types of terminal devices correspond to different physical meanings. For example, the URLLC terminal device corresponds to a power increment in which the transmit power or transmit power is not adjusted; the eMBB terminal device may correspond to a power reduction of the transmit power or stop transmitting. Therefore, different types of terminal equipment can only analyze the physical meaning corresponding to the terminal equipment, so that a plurality of terminal equipment can send target data based on the same first indication information, and signaling overhead is effectively reduced.

Or, the first indication information is used for indicating at least two of the following information:

the transmitting power is not adjusted;

a power increment of the transmit power;

a power reduction of the transmit power; and

and stopping transmission.

In some embodiments of the present application, the terminal device may determine target information from at least two kinds of information indicated by the first indication information according to the first information; and the terminal equipment sends or stops sending the target data according to the first information and the target information in the two information. Typically the first and second heat sinks are connected,

the terminal equipment determines target information in at least two kinds of information indicated by the first indication information according to the first information and a first corresponding relation, wherein the first corresponding relation is the corresponding relation between second information and at least two kinds of information of the following information, and the first corresponding relation is preconfigured information or information configured by network equipment:

The transmitting power is not adjusted;

a power increment of the transmit power;

a power reduction of the transmit power; and

stopping transmission;

the second information includes at least one of the following information:

the method comprises the steps of data service type, data service priority, service type supported by terminal equipment, format of first Downlink Control Information (DCI) for scheduling data, CORESET where the first DCI for scheduling data is located, search space where the first DCI for scheduling data is located, scrambling mode of the first DCI for scheduling data and scrambling mode of second DCI for carrying indication information.

Taking the first information as the service type of the target data as an example, the service type of the target data of the terminal equipment can be configured through the network equipment or the corresponding relation between at least two of the following information and the service type of the target data of the terminal equipment can be pre-configured: and not adjusting the transmitting power, the power increment of the transmitting power, the power reduction of the transmitting power and stopping transmission, so that the terminal equipment can determine target information in at least two pieces of information indicated in the first indication information according to the service type of the target data and the corresponding relation. However, the specific correspondence relation is not limited in the present application. For example, URLLC may correspond to a power increase without adjusting transmit power and/or transmit power, and ebmb may correspond to a power decrease in transmit power and/or stop transmission. For another example, URLLC may correspond to a power increase without adjusting transmit power and/or transmit power, and ebbb may correspond to at least one of without adjusting transmit power, a power increase in transmit power, a power decrease in transmit power, and stopping transmission.

Assuming that the first indication information is specifically used for indicating that the power of the transmission power is reduced by 3db and the power of the transmission power is increased by 3db, and the URLLC corresponds to the power increment of the transmission power, and the ebmb also corresponds to the power increment of the transmission power; at this time, when the service type of the target data is a URLLC service, the terminal device promotes 3db to send the data of the URLLC service; when the service type of the target data is the eMBB service, the terminal equipment can promote 1db to send the data of the eMBB service.

In connection with fig. 3, it is assumed that the first indication information sent by the network device is 000 for indicating to stop transmission, and UE2 has no additional operation because UE2 transmits URLLC traffic, and the received first indication information (i.e., stops transmission) is invalid thereto. However, since the UE3 transmits the eMBB traffic, the received first indication information (i.e., stops transmission) is valid thereto, and thus, the UE3 performs an action of stopping transmission. For another example, it is assumed that the first indication information sent by the network device is 001 for indicating a power boost of 3dB, and UE2 increases the uplink data transmission power by 3dB according to the signaling indication because the UE2 transmits the URLLC service, and the received first indication information (i.e., the power boost of 3 dB) is valid for the first indication information. However, UE3 does not have additional operations because UE3 transmits the eMBB traffic, and the received first indication information (i.e., the power boost of 3 dB) is not valid for it.

In some embodiments of the present application, the terminal device may receive the first indication information through Group common (downlink control information (Downlink control information, DCI) or may receive the first indication information through user equipment specific (UE specific) signaling, which is not limited in particular in embodiments of the present application.

The terminal device determines the physical meaning indicated by the first indication information corresponding to the first information according to the first information, and further sends or stops sending data according to the determined physical meaning, and the format of the first indication information is illustrated as Group common DCI.

The first indication information corresponds to a first resource, and the first resource comprises at least one of the following resources: time domain resources, frequency domain resources, and spatial domain resources. For example, the first indication information is information corresponding to all bandwidths activated in the first time unit.

Alternatively, the first indication information may be information transmitted to a plurality of terminal apparatuses.

Note that, the Group common DCI is information shared by a plurality of terminal apparatuses, that is, it is not required to transmit separately for each terminal apparatus, so that signaling overhead can be reduced. Taking the first time unit as 2 symbols as an example, the group common DCI may include 7 fields, where each field is used to carry a first indication information and corresponds to a full bandwidth resource in every 2 symbols in a slot. It should be appreciated that the full bandwidth may be the full bandwidth currently active. For example, for NR systems, the full Bandwidth may refer to the full Bandwidth of Active BWP because of the introduction of Bandwidth Part (BWP).

Format of table 2 Group common DCI

111

010

111

As shown in table 2, the Group common DCI corresponds to one slot, where the Group common DCI may include 7 pieces of first indication information, and each piece of first indication information corresponds to a full-bandwidth resource within every 2 symbols.

Fig. 4 is a schematic block diagram of the first indication information and resource correspondence of the embodiment of the present application.

As shown in fig. 4, when the scheduling resource of UE2 and the scheduling resource of UE3 collide, assuming that UE3 cannot stop transmitting immediately, the network device may instruct UE2 to increase power by 5dB through the first indication information, and as can be seen from table 1, the index of the first indication information is 010. Thus, the group common DCI may be {111 010 010 111 111 111 111}.

Thus, when UE2 reads the group common DCI, as it transmits URLLC on the corresponding resources (third-sixth symbol), then 5dB power is correspondingly boosted, if "010" is valid. When UE3 reads the group common DCI, no additional action is taken as "010" is invalid because it transmits an eMBB on the corresponding resource.

Accordingly, the network device detects UE2 data and detects UE3 data. Typically, an interference cancellation algorithm may be employed when receiving two terminal device data. Similarly, if the network device transmits a group common DCI of {111 000 000 111 111 111 111}, the network device detects only UE2 data.

In the embodiment of the application, two terminal devices (UE 2 and UE 3) with resource conflict indicate the UE3 to stop transmission through the group common DCI, and indicate the UE2 to promote 5dB power, so that the interference of eMBB can be eliminated or weakened, and the reliability of URLLC transmission is ensured. The interference coordination mechanism can be suitable for complex deployment environments, namely, under a unified working mechanism framework, various types of terminal equipment (terminal equipment capable of stopping transmission/terminal equipment incapable of stopping transmission and terminal equipment capable of improving power/terminal equipment incapable of improving power) can be adapted through reasonable configuration of network equipment, so that the difficulty in product realization and network deployment can be reduced, and the complexity in scheduling decision and standardization can be reduced.

In the method 200, when the terminal device does not have uplink data transmission, it does not cause any interference, and therefore, the network device may not need to send the first indication information to the terminal device. In view of the above, in some embodiments of the present application, the frequency of detecting the physical downlink control channel (Physical Downlink Control Channel, PDCCH) by the terminal device may be reduced by specifying the timing relationship between the resource location of the first indication information and the resource location of the target data, that is, the terminal device may only interpret the first indication information at the first indication information sending occasion corresponding to the resource of the transmission data, thereby avoiding blind detection of the PDCCH at the transmission occasions of all PDCCHs.

That is, the resource location of the first indication information and the resource location of the target data are separated by a second time unit. Alternatively, the resource location of the first indication information and the resource location indicated by the scheduling information for scheduling the target data are spaced apart by the second time unit.

It should be understood that the present application is not limited to the specific form of the second time unit.

For example, the second time unit may be at least one symbol. For example 1 or 2 symbols.

For another example, the second time unit may be at least one time slot. For example 1 or 2 time slots.

For another example, the second time unit may include at least one symbol and at least one slot.

As shown in fig. 5, assuming that UE 1-UE 3 has data transmission at slot n, UE 1-UE 3 reads DCI1. Assuming that UE4 has no transmission at slot n, UE4 does not read DCI1. Assuming that UE1 and UE4 have transmissions at slot n+1, UE1 and UE4 read DCI2, but because slot n+1 has no collision, the network device may not send DCI2, i.e., UE1 and UE4 may blindly detect DCI2, but may not detect it, and may not do additional actions.

It should be understood that the present application is not limited in any way to the specific implementation of the second time unit.

For example, the second time unit may be agreed between the terminal device and the network device in a negotiated manner.

For another example, the second time unit may be predefined, in particular may be defined by a protocol.

For another example, the second time unit may be preconfigured information. For example, the second time unit may be information that the network device configures to the terminal device.

For example, assume that the second time unit is specified by a protocol and is k symbols. In particular, it may be agreed by a protocol that k symbols are spaced between the resource location of the first indication information and the resource location of the target data, and when the terminal device has a transmission on symbol n, the first indication information is blindly detected on symbol n-k. Otherwise, the terminal equipment does not blindly detect the first indication information.

The first indication information is only used to indicate one of not adjusting the transmission power, a power increment of the transmission power, a power reduction of the transmission power, and stopping transmission. However, it should be understood that the first indication information may also be used to indicate that a plurality of the transmission power is not adjusted, the power increment of the transmission power, the power reduction of the transmission power, and the transmission is stopped. For ease of understanding, the first indication information is described by taking two of the indication of not adjusting the transmission power, the power increment of the transmission power, the power reduction of the transmission power, and the stop of transmission as an example.

In connection with fig. 3, assuming that a resource conflict occurs between UE3 for transmitting an eMBB and UE2 for transmitting a URLLC, the network device may instruct UE3 to reduce power and instruct UE2 to increase power through the first indication information.

When the network device determines that the UE2 cancels the energy of the eMBB interference (i.e., SINR required to maintain the target reliability) by boosting the transmission power, the network device transmits first indication information for indicating the UE2 to boost the power. Meanwhile, assuming that after the UE3 reduces the power, a larger power drop can be formed between the UE2 and the UE3, and meanwhile, the UE3 can be demodulated according to an expected target (for example, an expected BLER), the network device can instruct the UE3 to reduce the power through the first indication information at the same time.

Or, assuming that the network device determines that the UE2 is already power limited, that is, cannot boost the power substantially, even if the transmission power is boosted according to the maximum limit of the capability of the network device, the network device cannot cancel the energy of the ebb interference, and maintains the SINR required by the target reliability, the network device may instruct the UE2 to boost the power through the first indication information. Meanwhile, the first indication information indicates the UE3 to reduce power, so that the power lifted by the UE2 can offset the interference influence of eMBB.

At this time, the network device may preferentially demodulate UE2, and then based on the demodulation result of UE2, eliminate UE2 interference and further demodulate data of UE 3.

That is, the first indication information may be at least used to indicate both the uplink data power increase and the uplink power decrease, and a plurality of terminal devices may simultaneously transmit or stop transmitting target data according to the first indication information.

An exemplary description is provided below in connection with table 3.

Table 3 correspondence between index of first indication information and physical meaning

Index of first indication information	Meaning of physics
		000	Stopping transmission
001	The power is reduced by 3dB, and the power is increased by 3dB
		010	The power is reduced by 2dB, and the power is increased by 5dB
011	The power is reduced by 1dB, and the power is increased by 6dB
		100	Power boost 7dB
101	Power boost 8dB
		110	Power boost 9dB
111	Invalidation of

As shown in table 3, the first indication information may indicate 8 states, that is, one or two physical meanings corresponding to each index, through 3 bits.

In connection with fig. 3, when the network device determines that UE2 can cancel the energy of the eMBB interference, i.e., SINR required to maintain target reliability, by boosting the transmit power by 3 dB. Meanwhile, if the UE3 decreases the power by 3dB so that a larger power drop is formed between the UE2 and the UE3, and at the same time, the UE3 can demodulate according to an intended target (e.g., an intended BLER), the index of the first indication information may be 001.

In the embodiment of the application, the first indication information indicates a plurality of physical meanings, so that different types of terminal equipment analyze the physical meanings corresponding to the types of the terminals, and the signaling overhead can be effectively reduced.

Taking the example that the Group common DCI includes the first indication information, in conjunction with fig. 4, it is assumed that the Group common DCI includes the information field {111 001 001 111 111 111 111}, when UE1 reads the information field {111 001 001 111 111 111 111}, since it transmits URLLC on the corresponding resource (first-second symbol), but "111" is an invalid value, no additional operation is performed. When UE2 reads the information field 111 001 001 111 111 111 111, it sees "001" as a power boost, i.e. a 3dB power boost, since it transmits URLLC on the corresponding resources (third-sixth symbol). When UE3 reads the information field 111 001 001 111 111 111 111, it sees "001" as a reduced power, i.e. reduced 3dB power, since it transmits the eMBB on the corresponding resource.

Therefore, after the terminal equipment receives the first indication information, the physical meaning of the indication information needs to be determined by combining the service type of the target data or the type of the terminal equipment, and then the target data is sent or stopped to be sent according to the physical meaning.

In the embodiment of the application, two terminal devices (UE 2 and UE 3) with resource conflict indicate the UE3 to stop transmission through the group common DCI, and indicate the UE2 to promote 5dB power, so that the interference of eMBB can be eliminated or weakened, and the reliability of URLLC transmission is ensured. The interference coordination mechanism can be suitable for complex deployment environments, namely, under a unified working mechanism framework, various types of terminal equipment (terminal equipment capable of stopping transmission/terminal equipment incapable of stopping transmission and terminal equipment capable of improving power/terminal equipment incapable of improving power) can be adapted through reasonable configuration of network equipment, so that the difficulty in product realization and network deployment can be reduced, and the complexity in scheduling decision and standardization can be reduced. Further, when the first indication information indicates at least two physical meanings at the same time, the information used for data transmission by the two types of terminal equipment can be indicated at the same time through the first indication information, so that signaling can be further saved, and blind detection of the terminal equipment is reduced.

It can be found that, when the above technical solution is adopted, the following situations may exist:

the same data transmission covers a plurality of first indication information, and the physical meanings indicated by the plurality of first indication information are inconsistent.

At this time, in some embodiments of the present application, one indication information may be determined in the most robust manner among the plurality of first indication information, for the terminal device to determine how to transmit the target data, or whether to stop transmitting the target data.

Wherein the most robust manner may include at least one of:

the power increase may refer to an increase according to a maximum value indicated in the data transmission area, the power decrease may refer to a decrease according to a maximum value indicated in the data transmission area, and the stop of transmission may refer to a stop of transmission of the entire data transmission area, for example, the entire data area after at least receiving the first indication information.

As shown in fig. 6, two first indication information of the URLLC transmission region are {111, 010}, and as can be seen from table 3, if the terminal device determines that the maximum power boost is 5dB according to the first indication information, the entire URLLC transmission is boosted by 5dB, instead of merely boosting the transmission power on the 5 th-6 th symbol. The technical scheme of the embodiment of the application can keep the transmission power consistent, avoid discontinuous phase or inconsistent power of two parts caused by adjustment in the transmission process of radio frequency equipment, and further avoid that the pilot frequency positioned at the front part cannot accurately estimate the channel on the 5 th-6 th symbol, thereby influencing the demodulation performance.

In the above description, the terminal device needs to determine whether to use the first indication information based on the first information, or the terminal device needs to determine target information in at least one item of information indicated in the first indication information, and further determine whether to use and how to use the target information indicated by the first indication information according to the first information. But the present application is not limited thereto.

In other embodiments of the present application, the terminal device may first determine a first target resource corresponding to the first indication information; and then, when the terminal determines that the first target resource is a resource for transmitting the target data, the terminal equipment transmits or stops transmitting the target data according to the first indication information.

Specifically, the terminal device may determine the first target resource according to the first indication information and a second corresponding relationship, where the second corresponding relationship is a corresponding relationship between a plurality of target resources and at least two of the following information, and the second corresponding relationship is preconfigured information or information configured by the network device:

the transmitting power is not adjusted;

a power increment of the transmit power;

A power reduction of the transmit power; and

and stopping transmission.

As shown in fig. 7, the network side configures 4 Configured grant (Configured grant) resources for the terminal device 1. The network side dynamically configures scheduling (granted based) resources for the terminal device 2. The terminal 2 sends data on the grant based resources according to the dynamic scheduling signaling indication. At this time, the network side device sends power adjustment information to the terminal 1, which is used to instruct the terminal 1 to increase the sending power and overcome the interference caused by transmission on the grant based resource.

The following describes the embodiments in detail.

Example 1

The network device may configure at least one multicast TPC adjustment information for the terminal device, one multicast TPC adjustment information corresponding to at least one configured grant (configured grant) resource, and each field of the multicast TPC adjustment information corresponding to one user. The corresponding relation between the multicast TPC adjustment information and the configured grant resource and the corresponding relation between each domain of the multicast TPC adjustment information and the user are configured through high-layer signaling. Of course, the first indication information may also correspond to a group of users or a group of users, which is not limited in detail in the present application.

For example, the first information is a scrambling manner of a second DCI for carrying the first indication information; at this time, the terminal device determines the first target resource corresponding to the scrambling mode of the second DCI according to the scrambling mode of the second DCI. Of course, the corresponding relationship between the first indication information and the first target resource is preconfigured information or information configured by the network device, which is not limited in the present application.

As shown in fig. 7, assuming that the first indication information is multicast TPC adjustment information, the correspondence between the multicast TPC adjustment information and the configured grant resource may be implemented by TPC-PUSCH-RNTI-x correspondence. For example, the TPC-PUSCH-RNTI-1 scrambled multicast TPC adjustment information corresponds to configured grant resource 1; the multicast TPC adjustment information scrambled by TPC-PUSCH-RNTI-2 corresponds to configured grant resource 2; the TPC-PUSCH-RNTI-3 scrambled multicast TPC adjustment information corresponds to the configured grant resource 3, and the TPC-PUSCH-RNTI-4 scrambled multicast TPC adjustment information corresponds to the configured grant resource 4.

And when the terminal equipment receives the multicast TPC adjustment information scrambled by the TPC-PUSCH-RNTI-1 and the target data is sent on the configured grant resource 1, the terminal equipment adjusts the power according to the multicast TPC adjustment information scrambled by the TPC-PUSCH-RNTI-1 and sends on the configured grant resource 1.

When the terminal equipment transmits the multicast TPC adjustment information scrambled by the TPC-PUSCH-RNTI-1 and the multicast TPC adjustment information scrambled by the TPC-PUSCH-RNTI-2 on the configured grant resource 2, the terminal equipment adjusts the power according to the multicast TPC adjustment information scrambled by the TPC-PUSCH-RNTI-2 and transmits the power on the configured grant resource 2.

Example two

The network device may configure at least one TPC adjustment information for the user, wherein each field of TPC adjustment information corresponds to one configured grant resource. The corresponding relation between the domain of TPC adjustment information and configured grant resources is agreed by high-level configuration or protocol. Specifically, the TPC adjustment information first field corresponds to a first configured grant resource; the TPC adjustment information second domain corresponds to a second configured grant resource; the third domain of TPC adjustment information corresponds to a third configured grant resource; the TPC adjustment information fourth field corresponds to a fourth configured grant resource.

As shown in fig. 7, when the terminal receives one TPC adjustment information, the power adjustment information corresponding to the 4 domains is: { increase by 3db, remain unchanged }. When the terminal transmits data on the first configured grant resource, the transmission power is increased by 3dB, and when the terminal transmits data on the second configured grant resource, the transmission power is kept unchanged.

Example III

The network device may configure at least one multicast TPC adjustment information for the user, one multicast TPC adjustment information corresponding to at least one configured grant resource, and each field of the multicast TPC adjustment information corresponding to one configured grant resource of one user. The correspondence of each domain of the multicast TPC adjustment information to the user and the configured grant resources may be agreed by a higher layer configuration or protocol. Of course, the first indication information may also correspond to a group of users or a group of users, which is not limited in detail in the present application.

Referring to fig. 7, a first domain in the multicast TPC adjustment information corresponds to a first configured grant resource of a first user, a second domain corresponds to a second configured grant resource of the first user, a third domain corresponds to a third configured grant resource of the first user, a fourth domain corresponds to a fourth configured grant resource of the first user, a fifth domain corresponds to a first configured grant resource of the second user, a sixth domain corresponds to a second configured grant resource of the second user, a seventh domain corresponds to a third configured grant resource of the second user, and an eighth domain corresponds to a fourth configured grant resource of the second user.

When the first terminal receives the multicast TPC adjustment information, the information of the first to fourth domains is read as { 3db higher, kept unchanged }. When the first terminal transmits data on the first configured grant resource, the data is increased by 3dB, and when the first terminal transmits data on the second configured grant resource, the transmission power is kept unchanged.

It should be understood that when the traffic transmitted by the grant based includes URLLC and emmbb, the network side needs to indicate power adjustment information according to the traffic transmitted in the grant based.
