Description

Indication information communication method and device

Technical Field

The present application relates to communications technologies, and in particular, to a method and an apparatus for indicating information communication.

Background

Discontinuous Reception (DRX) is a technique for reducing power consumption of a terminal device in Long Term Evolution (LTE) communication. The DRX technology can allow the terminal device to enter a dormant state at some time of each DRX cycle without monitoring a Physical Downlink Control Channel (PDCCH); and entering an active state to monitor the PDCCH when the monitoring is needed at some time of the DRX period. Therefore, the terminal equipment can not be in the state of monitoring the PDCCH all the time, the purposes of saving the power consumption of the terminal equipment and improving the endurance capacity are achieved, and the user experience of the terminal equipment is improved.

In a New Radio (NR) system, since a proportion of high-speed data transmission traffic increases and a maximum rate is remarkably increased, data communicated between a terminal device and a network device may be generated in a burst form and completed in a short time. In order to further improve the performance of the terminal device, the NR further provides a mechanism (e.g., a Wake Up Signal (WUS) and a sleep signal (GTS) based on the DRX for further saving the power consumption of the terminal device, wherein in the mechanism of the WUS, the terminal device is in an active state and monitors a PDCCH or receives a Physical Downlink Shared Channel (PDSCH) in the DRX cycle if the WUS signal corresponding to the DRX cycle is received, the terminal device does not monitor the PDCCH or receive the PDSCH in the sleep state in the DRX cycle if the WUS signal corresponding to the DRX cycle is not received, and in the mechanism of the GTS, the terminal device is in the sleep state and does not monitor the PDCCH or receive the PDSCH in the DRX cycle if the GTS signal corresponding to the DRX cycle is received, the terminal device does not receive the WUS signal corresponding to the DRX cycle, it is in an active state and monitors the PDCCH or receives the PDSCH in the DRX cycle.

The method is more suitable for a GTS mechanism for terminal equipment with more services in an NR system, and the terminal can sleep through a GTS signal only when the service is finished when the terminal is frequently in an activated state; and terminal equipment with less services is more suitable for a WUS mechanism, and the terminal equipment is required to be frequently in a dormant state and only needs to be awakened through a WUS signal when the services are required to be processed. However, in the prior art, the WUS signal and the GTS signal can only be selected as power saving to be applied to all terminal devices in the NR system, and the NR system cannot dynamically determine more appropriate indication information for different terminal devices. Therefore, if the terminal device configured with the WUS mechanism has frequent services, the terminal device needs to additionally receive and process indication information of one WUS before each DRX period, so that the power consumption of the terminal device is not saved, and the power consumption of the terminal device is increased due to frequent receiving and processing of the indication information. If the terminal device configured with the GTS mechanism is not in frequent service, the terminal device in the sleep mode before each DRX cycle needs to receive and process indication information of a GTS, and the power consumption of the terminal device is also saved to a limited extent. Therefore, how to overcome the aforementioned problems caused by using a single type of indication information is a technical problem to be solved.

Therefore, the indication information communication method provided in this embodiment enables, when the terminal device processes different services on each activated CC or each activated BWP, the network device to issue the instruction information switching command for different services on different activated CCs or different activated BWPs according to the switching command and the mapping relationship. Specifically, the at least one parameter included in the handover command and the mapping relationship between the at least one parameter and the at least one activated CC or the at least one activated BWP enable the terminal device to determine, according to the mapping relationship, the handover of the indication information on the activated CC or the activated BWP corresponding to the received handover command, thereby enriching the application scenarios of the handover command and improving the indication efficiency of the handover command.

Optionally in an embodiment of the first aspect of the present application, before the terminal device receives the handover command from the network device, the method further includes:

if the terminal equipment judges that the service density between the terminal equipment and the network equipment meets the switching criterion, the terminal equipment sends a switching request to the network equipment; wherein the handover request is used for requesting the network device to handover the type of the indication information.

Optionally, in an embodiment of the first aspect of the present application, the switching criterion includes:

if the first type of indication information is a sleep signal GTS, the traffic density between the terminal device and the network device is lower than a first preset threshold;

and if the first type of power saving signal is a WUS, the traffic density between the terminal equipment and the network equipment is higher than a second preset threshold.

Therefore, the indication information communication method provided in this embodiment can determine, by the network device or the terminal device, whether to switch the type of the indication information according to the traffic density therebetween, and if it is determined that the type of the indication information needs to be determined according to the determination criterion, the network device sends the switching command to the terminal device, so that the terminal device completes switching of the type of the indication information, and thus, when the switching condition of the indication condition is satisfied, according to the switching command sent by the network device to the terminal device, the network device and the terminal device communicate with each other by using different indication information, thereby satisfying different usage scenarios of the terminal device, improving switching flexibility of the indication information of the terminal, and further reducing power consumption and communication overhead of the terminal device.

Therefore, the indication information communication method provided by this embodiment provides two different types of switching commands, and the terminal device can instruct the type switching of the indication information of the terminal device through any type of switching command.

Therefore, in the indication information communication method provided in this embodiment, since different types of indication information may have different signal designs, and the detection circuit or the receiving location used by the terminal device when receiving different types of indication information is different, in this step, when the terminal device configures the second type of configuration information, the first type of indication information needs to be compared with the second type of indication information. If the signal design of the first type of indication information and the second type of indication information is the same, or the related configuration information used by the terminal device to receive the first type of indication information and the second type of indication information is the same, the first type of configuration information used by the terminal device when monitoring the first type of indication information can be directly used as the second type of configuration information, and the existing configuration information of the terminal device does not need to be changed.

A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable smart device includes full functionality, large size, and can implement full or partial functionality without relying on a smart phone, such as: smart watches or smart glasses and the like, and only focus on a certain type of application functions, and need to be used in cooperation with other devices such as smart phones, such as various smart bracelets for physical sign monitoring, smart jewelry and the like.

In addition, in the embodiment of the present application, the terminal device may also be a terminal device in an internet of things (IoT) system, where IoT is an important component of future information technology development, and a main technical feature of the present application is to connect an article with a network through a communication technology, so as to implement an intelligent network with interconnected human-computer and interconnected objects.

In the embodiment of the present application, the IOT technology may achieve massive connection, deep coverage, and power saving for the terminal through, for example, a Narrowband (NB) technology. For example, the NB includes only one Resource Block (RB), i.e., the bandwidth of the NB is only 180 KB.

The present embodiment is not particularly limited to this.

It should be understood that, for convenience of understanding only, the network devices 11 to 13 and the communication devices are schematically illustrated in fig. 1, but this should not limit the present application in any way, and a greater or lesser number of network devices may also be included in the wireless communication system, and a greater number of communication devices may also be included, and the network devices communicating with different communication devices may be the same network device or different network devices, and the number of network devices communicating with different communication devices may be the same or different, which is not limited in the present application.

In the following, the communication between the network device 11 and the communication device 21 will be described simply by taking the network device and the communication device as examples.

The network device 11 may include 1 antenna or multiple antennas. Additionally, network device 11 can additionally include a transmitter chain and a receiver chain, each of which can comprise a plurality of components associated with signal transmission and reception (e.g., processors, modulators, multiplexers, demodulators, demultiplexers, antennas, etc.), as will be appreciated by one skilled in the art.

The network device 11 can communicate with a plurality of communication devices. The communication device 21 may be, for example, a cellular telephone, a smart phone, a laptop, a handheld communication device, a handheld computing device, a satellite radio, a global positioning system, a PDA, and/or any other suitable device for communicating over the communication system shown in fig. 1.

As shown in fig. 1, communication device 21 is in communication with network device 11, where network device 11 transmits information to communication device 21 over a forward link (also referred to as a downlink) and receives information from communication device 21 over a reverse link (also referred to as an uplink) network device 11.

For example, in a Frequency Division Duplex (FDD) system, the forward link and the reverse link use different frequency bands, for example.

As another example, in a Time Division Duplex (TDD) system and a full duplex (full duplex) system, the forward link and the reverse link may use a common frequency band.

Each antenna (or group of antennas consisting of multiple antennas) and/or area designed for communication is referred to as a sector of network device 11.

For example, antenna groups may be designed to communicate to communication devices in a sector of the area covered by network device 11. Network device 11 may transmit signals to all communication devices in its corresponding sector through single-antenna or multi-antenna transmit diversity. The transmitting antenna of network device 11 may also utilize beamforming to improve the signal-to-noise ratio of the forward link during communication of network device 11 with communication device 21 over the forward link.

Furthermore, mobile devices in neighboring cells may experience less interference when network device 11 utilizes beamforming to transmit to communication devices 21 scattered randomly through an associated coverage area than when network device 11 transmits through single or multiple antenna transmit diversity to all of its communication devices.

At a given time, the network device 11, the communication device 21 may be a wireless communication transmitting apparatus and/or a wireless communication receiving apparatus. When sending data, the wireless communication sending device may encode the data for transmission. Specifically, the wireless communication transmitting apparatus may acquire (e.g., generate, receive from other communication devices, or save in memory, etc.) a certain number of data bits to be transmitted over the channel to the wireless communication receiving apparatus. Such data bits may be contained in a transport block (or transport blocks) of data, which may be segmented to produce multiple code blocks.

In addition, the communication system shown in fig. 1 may be a PLMN network, a D2D network, an M2M network, an IoT network, or other networks, fig. 1 is a simplified schematic diagram for example, and other network devices or communication devices may be included in the network, which are not shown in fig. 1.

For ease of understanding, before introducing the present application to indicate an information communication method and apparatus, related terms and principles thereof referred to in the embodiments of the present application will be described below with reference to fig. 2, 3, and 4.

Fig. 2 is a diagram illustrating a DRX cycle structure in the prior art. As shown in fig. 2, Discontinuous Reception (DRX) is a technique for reducing power consumption of a terminal device in Long Term Evolution (LTE) communication, and a network device configures DRX functions for the terminal device in a connected state, an idle state, and an inactive state. For example, as shown in fig. 2, for a terminal device configured with a DRX function, in each DRX cycle, the terminal device is in an active state for an active time (On-Duration) of a previous part of each DRX cycle, and monitors a Physical Downlink Control Channel (PDCCH); and entering a dormant state at the dormant time after the activation time of the DRX period without monitoring the PDCCH. Meanwhile, the network device may guarantee that the PDCCH is transmitted to the terminal device at an active time in the DRX cycle of the terminal device. Specifically, in LTE, the DRX functional control entity is located in the MAC layer of the protocol stack, and its main function is to control sending of an instruction to the physical layer, notify the physical layer to monitor the PDCCH at a specific time, i.e. in an active period, and the terminal device is in a dormant state without turning on the receiving antenna at the rest of the time. Therefore, the terminal equipment can not be in the state of monitoring the PDCCH all the time, the purposes of saving the power consumption of the terminal equipment and improving the endurance capacity are achieved, and the user experience of the terminal equipment is improved.

In the New Radio (NR) system, since the proportion of high-speed data transmission traffic increases and the maximum rate is significantly increased, data communicated between the terminal device and the network device may be generated in bursts and completed in a short time. In order to further improve the performance of the terminal device, the NR may provide an additional indication information (it should be noted that all the indication information described in this application may also be referred to as a terminal power saving signal (UPSS), which is equivalent to the UE power saving signal) on a DRX basis, and the terminal device needs to determine whether the terminal performs a DRX mechanism in each DRX cycle according to the obtained indication information, that is, determine whether the terminal is in an active state at an active time of the DRX cycle corresponding to the indication information and monitors a PDCCH or receives a Physical Downlink Shared Channel (PDSCH). The network device can wake up the activation time of the terminal device in a certain DRX period through the indication information and is in an activation state to monitor the PDCCH when the PDCCH is determined to exist in the activation time of the DRX period, otherwise, the terminal device is in a dormant state all the time, so that the power consumption of the terminal device is further saved. Two common types of indication information include: a Wake Up Signal (WUS) and a sleep signal (GTS), which are described below.

When the indication information is WUS, the indication information is used for indicating whether the terminal monitors the PDCCH or indicating the terminal to monitor the PDCCH; or, the indication information is used to indicate whether the terminal receives the PDSCH or indicate that the terminal receives the PDSCH. Specifically, in the WUS mechanism, if a terminal device receives a WUS signal corresponding to a DRX cycle, the terminal device is in an active state in the DRX cycle and monitors a PDCCH or receives a PDSCH; and if the terminal equipment does not receive the WUS signal corresponding to the DRX period, the terminal equipment is in a dormant state in the DRX period and does not monitor the PDCCH or receive the PDSCH. Optionally, the indication information may be sent before the active time of the corresponding DRX cycle or during the active time of the corresponding DRX cycle, and for the terminal device in the RRC idle state, the indication information is sent before the DRX cycle; for a terminal device in RRC connected state and configured with DRX functionality, the indication information may be sent before the DRX cycle or during the active time of the DRX cycle. And when the network equipment sends the indication information to the terminal equipment, the network equipment does not send the indication information to the terminal equipment in each DRX period, but decides whether to send the indication information according to strategies such as the arrival situation of the service, the service delay requirement and the like. Therefore, the terminal device may monitor the indication information sent by the network device to other terminal devices in the DRX advanced duration indicated by the network device, and the terminal device may distinguish the indication information of different terminal devices in a code division manner. And when the terminal equipment receives the indication information, only a part of receiving circuits corresponding to the indication information in the terminal equipment need to be started, and the monitoring time is short.

For example, fig. 3 is a schematic diagram of an application of a WUS in the prior art, where an example is described in which indication information is a WUS and the indication information is sent before a DRX cycle of the DRX cycle, a time difference between an active time of the DRX cycle and receiving the WUS indication information is denoted as an advance duration GAP, when a network device and a terminal device are configured in advance at a specific advance duration GAP, the network device sends the indication information to the terminal device at the advance duration of the DRX cycle, and the terminal device receives the indication information sent by the terminal device at the advance duration of the DRX cycle. As shown in fig. 3, if the network device determines that the terminal device has a PDCCH or a PDSCH scheduled by the terminal device or a plurality of terminal devices in a DRX cycle (r), the network device sends a WUS instruction to the terminal device to wake up the terminal device in an advance duration before the DRX cycle (r), and after receiving the WUS, the terminal device is in an active state and monitors the PDCCH or the PDSCH in an activation time in the DRX cycle (r) corresponding to the time after the WUS. If the network equipment determines that the terminal equipment does not have the PDCCH or PDSCH scheduled by the terminal equipment or a plurality of terminal equipments in the DRX period, the WUS is not sent to the terminal equipment in the advance time before the DRX period, and the terminal equipment does not receive the WUS before the DRX period, so that the terminal equipment is in a dormant state in the whole DRX period. It should be noted that the heights of the various signals as in fig. 3 are merely used to characterize the relative current or power levels monitored by the various signals.

When the indication information is GTS, the indication information is used for indicating whether the terminal monitors the PDCCH or not, or indicating that the terminal does not monitor the PDCCH; alternatively, the indication information is used to indicate whether the terminal receives the PDSCH or to indicate that the terminal does not receive the PDSCH. Specifically, in the GTS mechanism, if the terminal device receives a GTS signal corresponding to the DRX, the terminal device is in a dormant state in the DRX cycle and does not monitor the PDCCH or receive the PDSCH; and if the terminal equipment does not receive the WUS signal corresponding to the DRX period, the terminal equipment is in an activated state in the DRX period and monitors the PDCCH or receives the PDSCH.

For example, fig. 4 is a schematic diagram of an application of a GTS in the prior art, which is also illustrated by taking an example that indication information is sent before a DRX cycle of the DRX cycle, where the indication information is the GTS. The time difference between the activation time of the DRX period and the receiving of the GTS indication information is recorded as an advance time GAP, when the network equipment and the terminal equipment are configured in advance at a specific advance time GAP, the network equipment sends the indication information to the terminal equipment in the advance time of the DRX period, and the terminal equipment receives the indication information sent by the terminal equipment in the advance time of the DRX period. As shown in fig. 4, if the network device determines that the terminal device does not have the PDCCH or PDSCH scheduled by the terminal device or the plurality of terminal devices in the DRX cycle (c), the network device sends the GTS to the terminal device in the advanced duration before the DRX cycle (c), and when the terminal device receives the GTS, the terminal device is in the sleep state in the whole DRX cycle (c) corresponding to the GTS. If the network equipment determines that the terminal equipment has the PDCCH or the PDSCH scheduled by the terminal equipment or the plurality of terminal equipments in the DRX period, the network equipment does not send GTS to the terminal equipment in the advance time before the DRX period, and the terminal equipment does not receive GTS before the DRX period, so that the terminal equipment is in an activated state in the activated time in the DRX period and monitors the PDCCH or the PDSCH. It should be noted that the heights of the various signals as in fig. 4 are also used only to characterize the relative current or power levels monitored by the various signals.

Although in the prior art, through the use of indication information such as WUS and GTS, a network device can wake up the active time of a terminal device in a certain DRX cycle through the indication information when determining that there are PDCCH or PDSCH of the terminal device or devices in the active time of the DRX cycle, and make the terminal device keep the active state to monitor PDCCH or receive PDSCH in the active time, otherwise, the terminal device is always in the sleep state even in the whole DRX cycle, thereby saving the power consumption of the terminal device to some extent. However, when the terminal device in the prior art uses the indication information, the WUS can be used in the GTS only by one, the network device only configures one of the WUS mechanism and the GTS mechanism for the terminal device, and there is no clear judgment basis for specifically configuring which indication information for each terminal.

In this way, for a terminal device configured with the WUS mechanism, before each DRX cycle in which a PDCCH needs to be monitored or a PDSCH needs to be received, the network device needs to send indication information WUS to the corresponding terminal device, so that the corresponding terminal device processes the indication information and is in an active state at the active time of the DRX cycle. Once the terminal device configured with the WUS mechanism has frequent services, the terminal device needs to additionally receive and process indication information of one WUS before each DRX cycle, which not only does not save power consumption of the terminal device, but also increases power consumption of the terminal device because frequent receiving and processing of the indication information. For the terminal device configured with the GTS mechanism, the network device sends the indication information GTS to the terminal device only before the terminal device does not need to monitor the PDCCH and receive the DRX cycle of the PDSCH, and once the terminal device configured with the GTS mechanism has infrequent traffic, the terminal device in the sleep mode before each DRX cycle needs to receive and process the indication information of one GTS, and the degree of saving power consumption of the terminal device is limited. Therefore, how to overcome the aforementioned problems in the current power saving signal application is a technical problem to be solved.

Therefore, the application provides a communication method of indication information, so that when the switching condition of the indication information is met, the network device sends a switching command to the terminal device, and after the terminal device takes the switching command into effect, another type of indication information is used between the network device and the terminal device, thereby meeting the dynamic changes of different use scenes and services of the terminal device, and further reducing the power consumption and the communication overhead of the terminal device.

The following describes an indication information communication method in the embodiments of the present application in detail with reference to the drawings.

Fig. 5 is a flowchart illustrating an embodiment of an indication information communication method according to the present application. The embodiment shown in fig. 5 may be implemented in the communication system shown in fig. 1, and the indication information communication method shown in fig. 5 includes:

s101: the network device generates a handover command, wherein the handover command is used for switching the type of the indication information from the first type to the second type.

Specifically, in S101, when the network device determines that the type of the indication information of the terminal device is switched from the first type to the second type, a switching command for instructing the terminal device to switch the type of the indication information from the first type to the second type is generated. It should be noted that the type of the indication information used by the terminal device before S101 is the first type, that is, the terminal device determines whether to perform the listening step according to monitoring the indication information of the first type. And after determining that the type of the indication information of the terminal equipment needs to be switched, the network equipment generates a switching command and sends the switching command to the terminal equipment so as to indicate the terminal equipment to switch the type of the indication information, so that the terminal equipment switches the type of the indication information from the first type to the second type, and determines whether to execute the monitoring step according to the indication information of the second type. The monitoring step described in this embodiment may be: the terminal equipment determines whether to monitor a Physical Downlink Control Channel (PDCCH), or monitor the PDCCH, or not according to whether indication information from the network equipment is received or not; or determining whether to receive the Physical Downlink Shared Channel (PDSCH), or receive the PDSCH, or not receive the PDSCH.

Optionally, the type of the indication information in this embodiment at least includes: a sleep signal GTS and a wake signal WUS, and the first type is different from the second type. Further optionally, if the indication information of the first type is GTS, the indication information of the second type is WUS; and if the first type of indication information is WUS, the second type of indication information is GTS.

Optionally, in this embodiment, one possible expression form of the handover command generated by the network device is that the handover command is used to express a certain type of indication information, or the handover command is used to express a certain type of indication information through one or more parameters carried by the handover command, for example: specifying a specific bit in the switching command to indicate the type of the indication information, wherein when the bit of the switching command is '0', the switching command is used for indicating to switch the type of the indication information to the first type; or when the bit of the switching command is "1", the switching command is used to instruct to switch the type of the indication information to the second type. For example, in S101 of this embodiment, if the switching command is used to switch the type of the indication information from the first type to the second type, the value of the specific bit of the switching command is "1".

Alternatively, another possible expression form of the handover command generated by the network device in this embodiment is that the handover command includes a type handover indication of the indication information, but does not include the type of the indication information. That is, the network device is only used to inform the terminal device whether the type of the indication information needs to be switched through the switching command, and when the type of the indication information needs to be switched, the terminal device specifically determines that the type of the indication information is changed from the first type to the second type. For example: when the switching command is '1', the switching command is used for instructing the terminal equipment to switch the type of the instruction information, and when the switching command is '0', the switching command is used for instructing the terminal equipment not to switch the type of the instruction information. Or, it may be only specified that the terminal device is instructed to switch the type of the indication information when the switching command is "1", the terminal device determines the type of the switching indication information when the switching command received is "1", and the terminal does not perform the switching of the indication information type when receiving the switching command with other values or receiving no switching command. After the terminal equipment receives the switching command, the terminal equipment executes the switching of the specific indication information. Here, only the representation form of the handover command is described, and the terminal device specifically determines the second type of indication information of the handover according to the handover command, which will be described in S103 in the subsequent embodiment of the present application.

S102: the network equipment sends a switching command to the terminal equipment; the terminal device receives a handover command from the network device.

Specifically, in S102, the network device transmits the handover command generated in S101 to the terminal device, and accordingly, the terminal device receives the handover command transmitted from the network device.

Optionally, the network device may send the handover command to the terminal device in the following form: downlink Control Information (DCI) and MAC CE are carried in DCI, MAC CE, Radio Resource Control (RRC) signaling, or system information.

If the types of the indication information of one terminal device in the cell are switched, the types of the indication information of other terminal devices in the cell also need to be switched correspondingly. When the network device sends the handover command to the terminal device, a possible way is to bear the handover command in the system information and send the handover command to all terminal devices in the cell where the terminal device is located in a broadcast manner, and after all terminal devices in the cell receive the system information, all terminal devices perform the handover of the indication information type according to the handover command borne in the system information. It should be noted that the system information here may be any existing system information or new system information communicated between the terminal device and the network device. The handover command may be carried by one or more specific bits, or spare bits, in the system information. For example, when the handover command is used to instruct the type of the terminal device to perform handover, the value of the corresponding bit is "1" or the values of the corresponding bits are "10", and when the type of the indication information used by the handover command for the terminal device does not need to perform handover, the value of the corresponding bit is "0" or the values of the corresponding bits are "01"; another example is: the switching command may also indicate multiple types of indication information switching of the terminal device through multiple bits, and if the terminal device may configure four types of indication information, the switching command may indicate the terminal device to switch to four types of indication information corresponding to one-to-one through "00", "01", "10", and "11", respectively.

When the types of the indication information adopted by each terminal device in the cell where the terminal device is located are not required to be consistent, that is, may not be completely the same, the handover command sent by the network device to the terminal device may indicate the handover command through a specially-set physical layer signal or an existing physical layer signal DCI, a specially-set or existing MAC CE, or the handover command may be carried in a certain specific bit in an existing or new DCI, MAC CE, or RRC signaling. For example: the handover command may be carried by one or more specific bits in the MAC CE. For a specific bit, the value of the bit in the MAC CE is "1" when the switching command indicates the type of the indication information of the terminal to be switched, and the value of the bit in the MAC CE is "0" when the switching command indicates the type of the indication information of the terminal not to be switched, for example: the switching command may indicate the type of indication information switching of the terminal device through a plurality of specific bits, and if the terminal device may configure four types of indication information, the switching command may indicate the terminal device to switch to the corresponding type of indication information through "00", "01", "10" and "11", respectively.

S103: and the terminal equipment determines the second type of configuration information according to the switching command.

Specifically, in S103, the terminal device processes the handover command received in S102, and the terminal device determines the second type of configuration information according to the handover command. Wherein, since the terminal device determines whether to perform the monitoring step by monitoring the first type of indication information before S101, and the switching command received by S102 is a type for instructing the terminal device to switch the indication information, and switches to determining whether to perform the monitoring step by monitoring the second type of indication information, S103 may be understood as the terminal device taking effect on the switching command from the network device, that is, the terminal device configuring for monitoring the second type of indication information to implement the switching of the indication information, or more specifically modifying/switching the monitoring first type of configuration information into the second type of configuration information.

Optionally, the terminal device may configure/store different configuration information corresponding to different types of indication information in advance, and when receiving the switching command, the terminal device may directly select to execute the configured configuration information of the corresponding type or obtain and configure the stored configuration information of the corresponding type from the storage space according to the type indicated by the switching command.

Optionally, the determining the second type of configuration information in this embodiment at least includes the following steps: if the terminal equipment judges that the monitoring circuit used by the terminal equipment for monitoring the first type of indication information is different from the monitoring circuit used by the terminal equipment for monitoring the second type of indication information, the terminal equipment switches the detection circuit for monitoring the first type of indication information into the monitoring circuit for monitoring the second type of indication information; and/or if the terminal equipment judges that the monitoring positions used by the terminal equipment for monitoring the first type of indication information and the second type of indication information are different, the terminal equipment switches the monitoring position of the first type of indication information to the monitoring position of the second type of indication information.

Specifically, since different types of indication information may have different signal designs, and thus the detection circuits or receiving positions used by the terminal device when receiving different types of indication information are different, in this step, when the terminal device configures the second type of configuration information, the first type of indication information needs to be compared with the second type of indication information. If the signal design of the first type of indication information and the second type of indication information is the same, or the related configuration information used by the terminal device to receive the first type of indication information and the second type of indication information is the same, the first type of configuration information used by the terminal device when monitoring the first type of indication information can be directly used as the second type of configuration information, and the existing configuration information of the terminal device does not need to be changed. Conversely, if the terminal device determines that the signal designs of the first type of indication information and the second type of indication information are different, the configuration information of the relevant indication information needs to be changed. If the monitoring circuit used for monitoring the first type of indication information is different from the monitoring circuit used for monitoring the second type of indication information, the monitoring circuit of the terminal device needs to be adjusted to the monitoring circuit used for the second type of indication information in this step. If the receiving position of the terminal device for receiving the first type of indication information is different from the receiving position for receiving the second type of indication information, the receiving position of the terminal device for receiving the second type of indication information needs to be adjusted to the receiving position of the second type of indication information in this step. For example, the receiving position here may be a time domain position, a frequency domain position, or a time-frequency position where the terminal device receives the indication information. In addition, if the terminal device determines that the signal designs of the first type of indication information and the second type of indication information are different, the configuration information of the first type of indication information may be changed into the configuration information of the second type of indication information, where the configuration information may also be a scrambling method of the indication information or an encryption/decryption method of the indication information.

Optionally, after S102 and before S103, the method further includes: the terminal equipment starts a timer with preset time; and performs S103 after the timer expires. Specifically, the terminal device may not immediately execute the handover command after receiving the handover command according to the service arrival condition of the terminal device, the service delay requirement, or other policies of the terminal device, but start a timer with a preset time, where the preset time may be adjusted by the terminal device or the network device according to the service requirement, so as to meet the requirements of different services. When the timer times out, the terminal device performs the configuration of the second type of configuration information in S103 again. Before the timer is overtime, the terminal equipment maintains the first type of configuration information of the first type of indication information before receiving the switching command, and determines whether to execute the monitoring step or not according to the first type of indication information; and determining the second type of configuration information after the timer is overtime, and determining whether to execute the monitoring step through the second type of indication information.

Optionally, as described in an embodiment in S101, if the handover command only includes the type handover indication of the indication information, and the handover command does not include the specific type of the indication information, in S103, the terminal device further needs to determine the second type of indication information to be handed over according to the handover command, and then determine the configuration information corresponding to the second type of indication information.

For the terminal device, one possible processing manner of the type of the switching command is that, if the terminal device only configures two types of indication information, once the terminal device receives the switching command, the currently configured indication information is switched to another type. For example: taking GTS and WUS as examples, the terminal device determines whether to execute the monitoring step by monitoring the GTS, and when receiving a switching command, the terminal device determines to switch the type of the indication information from the GTS to the WUS, then determines the configuration information of the type corresponding to the indication information WUS, and determines whether to execute the monitoring step by the WUS.

Another possible implementation is: and after receiving the switching command, the terminal equipment determines the configuration information of the second type according to the switching command, the currently configured indication information of the first type and the switching relation. Wherein the switching relationship includes a conversion relationship between various types of the indication information. The switching relation may be that the terminal device is configured in advance and stored in a storage device of the terminal device; or the switching relation can also be carried in the switching command and sent to the terminal device by the network device in real time, and the switching relation can be adjusted by the network device in real time according to the service condition. It is assumed that the terminal device is capable of monitoring three types of indication information A, B and C, and therefore the handover relationship of the terminal device includes: and after the terminal equipment receives a switching command, the type of the indication information needs to be switched according to the switching relation. For example, the terminal device determines whether to perform the listening step by monitoring the indication information of the a type. After the terminal device receives the switching command, the terminal device determines that the type of the indication information needs to be switched from the type a to the type B according to the switching command, the type a of the currently monitored indication information and the switching relationship of "a-B" in the switching relationship, that is, the second type of configuration information is determined to be the type B configuration information corresponding to the type B indication information. And determining whether to execute the monitoring step by monitoring the indication information of the type B after the switching command takes effect. It should be noted that the switching relationship is merely an example, and the switching relationship may further include a variety of conversion relationships, such as a-C, B-C, and C-a, and is not limited herein.

Optionally, after S103 and before S104, the method further includes: the terminal equipment sends switching confirmation information to the network equipment; the switching confirmation information is used to notify the network device that the terminal device has executed the determination of the second type of configuration information in S103, that is, the terminal device has validated the switching command, and configured the second type of configuration information, and has been able to execute the instruction information for monitoring the second type. Therefore, the terminal device can send confirmation information to the network device for confirmation after the handover command has been validated through S103, so that both the network device and the terminal device confirm the handover of the type of the instruction information. Therefore, the situation that the network equipment sends the second type of indication information to the terminal equipment when the second type of configuration information cannot be monitored and the terminal equipment is not configured with the second type of configuration information due to the performance of the terminal equipment or network delay during the communication of the indication information is avoided.

S104: and the terminal equipment monitors the second type of indication information according to the second type of configuration information.

Specifically, in this embodiment, after the terminal device determines the configuration information of the second type through S103, the indication information of the second type is monitored according to the configuration information of the second type. Wherein monitoring the second type of indication information comprises: it is determined whether to perform the listening step by whether the second type of indication information is received. And the terminal equipment changes the monitoring of the first type of indication information before receiving the switching command into the monitoring of the second type of indication information. Optionally, the monitoring step includes: the terminal determines whether to monitor a Physical Downlink Control Channel (PDCCH), or monitor the PDCCH, or not according to whether to receive the second type of indication information from the network equipment; or determining whether to receive the Physical Downlink Shared Channel (PDSCH), or receive the PDSCH, or not receive the PDSCH.

Optionally, the handover command sent by the network device to the terminal device further includes a duration of the handover command. That is, after receiving the handover command and executing S103, the terminal device executes the monitoring of the second type of indication information according to the second type of configuration information in S104 within the duration; and after the duration, the terminal equipment determines and configures the configuration information of the first type again, and monitors the indication information of the first type according to the configuration information of the first type. Therefore, the network equipment can indicate the terminal equipment to switch to monitoring the second type of indication information within a certain time according to the service requirement. The terminal equipment recovers and monitors the first type of indication information before receiving the switching command after the period of time, so that the flexibility of indication information switching is improved, and the application scene is enriched.

In summary, in the communication method for indicating information provided in this embodiment, a switching command is generated by a network device and sent to a terminal device, where the switching command is used to switch the type of the indicating information from a first type to a second type, so that the terminal device determines the configuration information of the second type according to the switching command after receiving the switching command, and monitors the indicating information of the second type according to the configuration information of the second type. Therefore, the terminal equipment can switch different indication information for communication, thereby meeting the dynamic changes of different use scenes and services of the terminal equipment, improving the switching flexibility of the indication information of the terminal, and further reducing the power consumption and the communication overhead of the terminal equipment.

Further, in the above embodiments, the communication scenario of the terminal device is not limited, and the instruction command sent by the network device to the terminal device is not limited to processing a certain communication or a certain communication type of the terminal device. That is, after receiving the handover command, the terminal device applies the handover of the indication information type indicated by the handover command to all possible communication scenarios of the terminal device. For example, the terminal device has indication information that needs to be monitored on a plurality of Component Carriers (CCs) in a Carrier Aggregation (CA) communication scenario, or has indication information that needs to be monitored on one or more bandwidth parts (BWPs) in a BWP communication scenario where the terminal device has one or more BWPs on its carrier. At this time, the terminal device applies the switching of the indication information type to all active CCs or all active BWPs of the terminal device. Although such a handover has already achieved the purpose of switching the indication information type, when the terminal device processes different services on each CC or each BWP, the network device cannot issue the command indicating information type switching for different services on different CCs or different BWPs according to the switching command, and cannot accurately switch the indication information type for a certain activated CC or activated BWP. Therefore, in order to solve the above-mentioned problems, enrich the application scenarios of the handover command and improve the efficiency of instructing the handover command, the present application further provides an instruction information communication method, on the basis of the foregoing embodiments, to enable the terminal device to determine the type of instruction information for handing over a specific CC or a specific BWP according to the handover command sent by the network device.

On the basis of the foregoing, the steps executed by the terminal device in S103 provided in this embodiment are: the terminal equipment determines second type indication information and configuration information thereof on at least one activated CC or at least one activated BWP according to the switching command and the mapping relation; the steps executed by the terminal device in S104 are: the terminal device monitors the indication information of the second type on at least one activated CC or at least one activated BWP according to the configuration information of the second type. Specifically, the present embodiment can be realized as follows. The handover command provided in this embodiment includes: at least one parameter. At least one parameter is mapped with at least one activated component carrier CC or at least one activated bandwidth part BWP; the at least one parameter is used to indicate that there is a mapping relationship between at least one activated CC or a type of indication information on at least one activated BWP. It corresponds to the above-described embodiment that,

alternatively, the mapping relationship here may be configured in advance in the terminal device by the network device, and the terminal device may use the mapping relationship when needed. Alternatively, the mapping may also be carried in the handover command,

it should be noted that the parameter included in the handover command described in the embodiments of the present application may be a command or information represented by at least one bit, and each parameter may be considered as a handover command of an indication information type on an active CC or an active BWP corresponding to the parameter independently.

The following describes the present embodiment according to a method for switching indication information types in four different application scenarios of the terminal device.

The first application scenario is that when the terminal device is in non-CA communication, there is only one communication carrier and there is only one active BWP on the carrier. The handover command at this time may include: a parameter. At this time, the terminal device determines the type of the indication information for switching the active BWP according to the handover command after receiving the handover command. Assuming that the active BWP originally monitors the first type of indication information, the terminal device needs to determine the second type of configuration information on the active BWP according to the handover command, and then monitor the second type of indication information on the active BWP through the second type of configuration information. The implementation process of this embodiment is the same as the process shown in fig. 5, and the implementation manner and principle are the same as fig. 5, which are not described again.

The second application scenario is that when the terminal device is in non-CA communication, only one communication carrier exists and multiple active BWPs exist on the carrier. The handover command at this time may include: at least one parameter; the mapping relation comprises the following steps: when the at least one parameter is a plurality of parameters, the parameters and the activated BWPs are in one-to-one correspondence; or, when the at least one parameter is one or more parameters, the corresponding relationship between each parameter in the at least one parameter and the plurality of activated BWPs; or, when the at least one parameter is a plurality of parameters, the correspondence between a combination of parameters composed of the plurality of parameters in the at least one parameter and the plurality of activated BWPs. Therefore, the switching command received by the terminal device from one active BWP can be realized, and the switching of the type of the indication information on other active BWPs can be realized.

That is, the mapping relationship of the present embodiment includes three possible implementation manners: when at least one parameter is multiple parameters, each of the multiple parameters corresponds to one activated BWP, and the two parameters are in a one-to-one correspondence relationship, for example, there are 3 activated BWPs on one carrier for non-CA communication of the terminal device, and the network device wants to control PDCCH monitoring or PDSCH receiving on the three activated BWPs of the terminal device respectively because the 3 activated BWPs may carry different services. Therefore, the handover command may include 3 parameters, and assuming that the 3 parameters in the form of bits are "000", the mapping relationship is that each bit corresponds to 3 activated BWPs, and if the parameter is 1, the type of indication information indicating the corresponding activated BWP is switched. When the terminal receives the handover command "100", it determines that the type of the indication information on the first active BWP needs to be handed over according to the handover command and the mapping relationship, and performs the subsequent handover action. And each parameter in the at least one parameter corresponds to a plurality of activated BWPs, and the parameters and the BWPs are in one-to-many relationship. When the at least one parameter is one, the one parameter is used for corresponding to all the activated BWPs in the plurality of activated BWPs, and when the at least one parameter is a plurality, each parameter may correspond to a different plurality of activated BWPs, respectively. For example: there are 4 active BWPs on a carrier of the non-CA communication of the terminal device, and when the handover command is a parameter, the mapping relationship may be a one-to-many correspondence relationship between a parameter and the 4 active BWPs. Still alternatively, when the handover command is two parameters, the mapping relationship may be a one-to-many correspondence relationship between one parameter and 2 of the active BWPs and a correspondence relationship between the other parameter and the other 2 of the active BWPs. Assuming that two parameters in the form of bits are "00" and the mapping relationship is that the first bit and the second bit correspond to the front and back 2 active BWPs, respectively, when the terminal device receives the handover command "10", it determines that the type of the indication information on the first two active BWPs in the 4 active BWPs needs to be switched according to the handover command and the mapping relationship. And the at least one parameter is a plurality of parameters, and the plurality of parameters and the plurality of activated BWPs have corresponding relations. For example, assuming that the handover command includes at least 3 parameters "000", while assuming that there are 8 active BWPs, the 3 parameters may correspond to any one or more of the 8 active BWPs, for example: 000 for all 8 active BWPs; 001 corresponds to the first active BWP; 010 corresponds to the first two activated BWPs, etc. Alternatively, any of the plurality of parameters may form a parameter combination, and any of the plurality of active BWPs may also form a BWP combination, so as to establish a correspondence between the parameter combination and the BWP combination. For another example, the 3 parameters in the above example may also form the corresponding relationship between the parameter combination and the BWP combination in a combined form, for example, the 3 parameters may be combined into 8 parameters: "000" "001" … … "111"; according to the ID of 8 active BWPs being 1-8, respectively, 8 active BWPs can compose at least 8 different BWP combinations: combination 1: 1; and (3) combination 2: 1-2; … … combination 8: 1-8. Then 8 parameter combinations formed by 3 parameters in the handover command can be in one-to-one correspondence with 8 different BWP combinations in 8 active BWPs, e.g. the parameter combination "000" corresponds to BWP combination 1; parameter combination "001" corresponds to BWP combination 2; … …, respectively; parameter combination "111" corresponds to BWP combination 8.

The third application scenario is that when the terminal device is in CA communication, there are multiple activated CCs and only one activated BWP exists on each activated CC. The handover command at this time may include: at least one parameter; the mapping relation comprises the following steps: when the at least one parameter is a plurality of parameters, the plurality of parameters and the plurality of activated CCs are in one-to-one correspondence; or, when the at least one parameter is one or more parameters, the corresponding relationship between each parameter in the at least one parameter and the plurality of activated CCs; or, when the at least one parameter is a plurality of parameters, a correspondence between a parameter combination composed of the plurality of parameters in the at least one parameter and the plurality of activated CCs. Therefore, the switching command received by the terminal equipment from one activated CC can be realized, and the switching of the type of the indication information on other activated CCs can be realized. In particular, at the time of CA communication, the network device may send a handover command only on the CC of the primary cell, while enabling handover of the indication information type on the CC of the primary cell and/or any activated secondary cell.

Similarly, the mapping relationship of the embodiment includes three possible implementation manners: when at least one parameter is multiple parameters, each of the multiple parameters corresponds to one activated CC, and the two parameters are in a one-to-one correspondence relationship, for example, there are 3 activated CCs during CA communication of the terminal device, and the network device wants to control PDCCH monitoring or PDSCH receiving on the three activated CCs of the terminal device respectively because the 3 activated CCs may carry different services. Therefore, the handover command may include 3 parameters, and assuming that the 3 parameters in the form of bits are "000", the mapping relationship is that each bit corresponds to 3 activated CCs one by one, and assuming that the parameter is 1, the type of indication information indicating the corresponding activated CCs is switched. When the terminal receives the switching command '100', it determines the type of the indication information on the first activated CC to be switched according to the switching command and the mapping relationship, and performs the subsequent switching action. And each parameter in the at least one parameter corresponds to a plurality of activated CCs, and the two parameters are in one-to-many relationship. When at least one parameter is one, the one parameter is for all activated CCs in the corresponding plurality of activated CCs; when the at least one parameter is plural, each parameter may correspond to a different plurality of activated CCs, respectively. For example: when the terminal device CA communicates with 4 activated CCs, and the handover command is a parameter, the mapping relationship may be a one-to-many correspondence relationship between the parameter and the 4 activated CCs. Still alternatively, when the handover command is two parameters, the mapping relationship may be a one-to-many correspondence relationship between one parameter and 2 of the activated CCs and a correspondence relationship between the other parameter and the other 2 of the activated CCs. Assuming that two parameters in the form of bits are "00" and the mapping relationship is that the first bit and the second bit correspond to the front and back 2 activated CCs, respectively, when the terminal device receives the switching command "10", the type of the indication information on the front two activated CCs among the 4 activated CCs needs to be switched according to the switching command and the mapping relationship. And thirdly, at least one parameter is a plurality of parameters, and a corresponding relation exists between a parameter combination formed by the parameters and the activated CCs. For example, assuming that the handover command includes at least 3 parameters "000", and assuming that there are 8 activated CCs, the 3 parameters may correspond to any one or more of the 8 activated CCs, for example: 000 for all 8 activated CCs; 001 corresponds to the first activated CC; 010 corresponds to the first two activated CCs, etc. Alternatively, any multiple parameters of the multiple parameters may form one parameter combination, and multiple activated CCs of the multiple activated CCs may also form one CC combination, so as to establish a corresponding relationship between the parameter combination and the CC combination. For another example, the 3 parameters in the above example may also form the corresponding relationship between the parameter combination and the CC combination in a combined form, for example, the 3 parameters may be combined into 8 parameter combinations: "000" "001" … … "111"; according to the ID of 8 activated CCs being 1-8, respectively, the 8 activated CCs may be grouped into at least 8 different CC combinations: combination 1: 1; and (3) combination 2: 1-2; … …, respectively; and (4) combination 8: 1-8. Then 8 parameter combinations consisting of 3 parameters in the handover command can be in one-to-one correspondence with 8 different BWP combinations of 8 activations, e.g. parameter combination "000" corresponds to CC combination 1; the parameter combination "001" corresponds to CC combination 2; … …, respectively; parameter combination "111" corresponds to CC combination 8.

The fourth application scenario is that when the terminal device performs CA communication, multiple activated CCs exist and multiple activated BWPs exist on each activated CC. The handover command at this time may include: at least one parameter; the mapping relation comprises the following steps: a one-to-one correspondence between the plurality of parameters and each activated BWP in each of the plurality of activated CCs when the at least one parameter is the plurality of parameters; or, when the at least one parameter is one or more parameters, a correspondence between each parameter of the at least one parameter and one or more activated BWPs in the one or more activated CCs; or when the at least one parameter is a plurality of parameters, a correspondence between a combination of parameters composed of the plurality of parameters in the at least one parameter and one or more activated BWPs possessed by the one or more activated CCs. That is, in this embodiment, it may not be considered from which activated CC each activated BWP comes, and one or more activated BWPs corresponding to each parameter combination may be activated BWPs possessed by the same or different activated CCs. Therefore, the switching command received by the terminal device from one BWP that one activated CC has can be realized, and the switching of the type of the indication information of other BWPs can be realized. In particular, at the time of CA communication, the network device may transmit a handover command only on the CC of the primary cell, while enabling handover of the indication information type of the activated BWP on the CC of the primary cell and/or on the CC of any activated secondary cell.

Similarly, the mapping relationship of the embodiment includes three possible implementation manners: when at least one parameter is a plurality of parameters, each parameter in the plurality of parameters corresponds to a corresponding relationship between every activated BWPs in every activated CC, and the parameters and the activated BWPs are in a one-to-one corresponding relationship. For example: there are 2 active CCs for the terminal CA to communicate, each active CC has 2 active BWPs, so the handover command needs to include 4 parameters, which are represented as "0000" in the form of bits, where each parameter corresponds to a total of 4 active BWPs on the 2 active CCs. And secondly, each parameter in the at least one parameter corresponds to a plurality of BWPs, and the plurality of active BWPs may be possessed by one active CC or a plurality of active CCs. For example, when at least one parameter is one parameter, the one parameter is used to correspond to all BWPs on all activated CCs, and thus the mapping relationship may be a one-to-many correspondence relationship between the one parameter and a total of 4 activated BWPs on 2 activated CCs. Still alternatively, when the at least one parameter is a plurality of parameters, each of the parameters may correspond to a plurality of BWPs on one or more activated CCs, respectively, for example, when the handover command is two parameters, the mapping relationship may include a one-to-two correspondence relationship between one of the parameters and a first activated BWP of a first activated CC and a first activated BWP of a second activated CC, and a one-to-two correspondence relationship between another parameter and a second activated BWP of the second activated CC. Assuming that two parameters in the form of bits are "00", when the terminal device receives the handover command "10", it is determined that the type of the indication information on the first active BWP of the first active CC and the first active BWP of the second active CC needs to be switched according to the handover command and the mapping relationship. And the at least one parameter is a plurality of parameters, and a corresponding relation exists between a parameter combination formed by the parameters and a plurality of BWPs possessed by one or a plurality of activated CCs. For example, assume that the handover command includes at least 3 parameters "000", while assume that there are 2 active CCs, each with 4 active BWPs, for a total of 8 active BWPs. Then 3 parameters may correspond to any one or more of a total of 8 active BWPs, for example: 000 for all 8 active BWPs; 001 corresponds to the first active BWP on the first active CC; 010 corresponds to all active BWPs on the first active CC, etc. Alternatively, any number of the plurality of parameters may form a parameter combination, and any number of the plurality of activated BWPs in the one or more activated CCs may also form an activated BWP group to establish a correspondence between the parameter combination and the BWP combination, and the plurality of BWPs in the BWP combination may be from the one or more activated CCs. For another example, the 3 parameters in the above example may constitute 8 parameter combinations: "000" "001" … … "111"; a total of 8 active BWPs may constitute at least 8 different BWP combinations: combination 1: 1; and (3) combination 2: 1-2; … … combination 8: 1-8. Then 8 parameter combinations formed by 3 parameters in the handover command can be in one-to-one correspondence with 8 BWP combinations, e.g. parameter combination "000" corresponds to BWP combination 1; parameter combination "001" corresponds to BWP combination 2 … … parameter combination "111" corresponds to BWP combination 8. The BWP groups herein may not consider from which activated CC each activated BWP comes, and the activated BWPs included in each group may be activated BWPs on the same or different activated CCs.

Further, in each of the above embodiments, in S101, the network device generates the switching command after determining that the indication information of the terminal device needs to be switched from the first type to the second type. And how to make the network device determine that the handover command can be generated specifically, the present application provides several methods for determining that the network device generates the handover command, which are described below with reference to fig. 6 and 7.

Fig. 6 is a flowchart illustrating an embodiment of an indication information communication method according to the present application. The embodiment shown in fig. 6 shows a method in which the terminal device determines whether to switch the type of the indication information according to the switching criterion, and if the terminal device determines that the type of the indication information needs to be switched, the terminal device sends a switching request to the network device to request the type of the indication information to be switched. As shown in fig. 6, the present embodiment further includes, before S101, on the basis of the embodiment shown in fig. 5:

s201: the terminal equipment judges that the service density between the terminal equipment and the network equipment meets the switching criterion; then the execution of S202: the terminal equipment sends a switching request to the network equipment; wherein the handover request is used for requesting the type of the handover indication information from the network device. In addition, if the terminal device determines that the traffic density between the terminal device and the network device does not satisfy the handover criterion, the terminal device does not send a handover request to the network device, and the network device does not execute the subsequent S101 to generate a handover command if the network device does not receive the handover request. That is, when the terminal device determines that the traffic density between the terminal device and the network device does not satisfy the handover criterion, the type of the indication information of the existing terminal device is kept from being handed over.

Alternatively, the determination of the traffic density between the terminal device and the network device in S201 may be configured to be performed periodically, and the determination of the traffic density between the terminal device and the network device in S201 is performed once every fixed time interval by the terminal device.

Specifically, the present embodiment provides the following possible setting manner of the switching criterion for example. For example, the handover criteria include: if the first type of indication information is GTS, the service density between the terminal equipment and the network equipment within a fixed time length T is lower than a first preset threshold value; and if the first type of indication information is WUS, the service density between the terminal equipment and the network equipment within the fixed time length T is higher than a second preset threshold value. The traffic density may be the number of Data Radio Bearers (DRBs) of the terminal device, the sum of the throughputs of the DRBs of the terminal device, the average throughput of the DRBs of the terminal device or the maximum DRB throughput of the terminal device, or the number of times that the terminal device is paged in a unit time.

If the first type of indication information is GTS, for a terminal device configured with a GTS mechanism, the network device sends the indication information GTS to the terminal device only before or during a DRX cycle that does not need to monitor a PDCCH and receive a PDSCH. Therefore, once the terminal device determines that the traffic density between the terminal device and the network device is lower than the first preset threshold, the terminal device determines that the traffic is infrequent, and does not need to monitor the PDCCH or receive the PDSCH in most DRX cycles, and the network device does not need to send GTS indication information to the terminal device before each DRX cycle, and at this time, the GTS indication information of the first type needs to be switched to the GTS indication information of the second type, so as to reduce transmission of the GTS indication information. Preferably, the switching criterion may further indicate that the GTS is switched to the WUS when the traffic density is lower than the first preset threshold.

If the first type of indication information is WUS, for a terminal device configured with a WUS mechanism, before or during each DRX cycle in which a PDCCH needs to be monitored or a PDSCH needs to be received, the network device needs to send the indication information WUS to the terminal device, so that the terminal device processes the indication information and is in an active state at the active time of the DRX cycle. Therefore, once the terminal device determines that the traffic density between the terminal device and the network device is higher than the first preset threshold, the terminal device determines that the traffic is frequent, and needs to monitor the PDCCH or receive the PDSCH in most DRX cycles, that is, the network device does not need to send WUS indication information to the terminal device before each DRX cycle, and at this time, the WUS indication information of the first type needs to be switched to the WUS indication information of the second type, so as to reduce the transmission of the WUS indication information. Preferably, the switching criterion may further indicate that the WUS is switched to the GTS when the traffic density is higher than the second preset threshold.

Therefore, the present application provides a communication method of indication information, so that when a terminal device determines that the traffic density between the terminal device and a network device meets a switching criterion, the terminal device sends a switching request to the network device, and then the network device sends a switching command to the terminal device, so that the network device and the terminal device communicate using different indication information, thereby meeting different usage scenarios of the terminal device, improving the switching flexibility of the indication information of the terminal, and further reducing the power consumption and communication overhead of the terminal device.

Optionally, in the embodiment shown in fig. 6, after the network device receives the handover request sent by the terminal device in S202, the network device further needs to determine the handover request of the terminal device, and determine whether the terminal device can perform handover according to the type of the indication information requested by the terminal device. If the switching of the indication information type can be carried out, the network equipment executes S101 again to generate a switching command of the terminal equipment; if it is judged that the switching of the indication information type cannot be performed, the network device does not perform S101 for generating a switching command of the terminal device.

Optionally, when the network device determines that the indication information type cannot be switched according to the switching request of the terminal device, the terminal device may further notify the terminal device that the switching request is invalid in a form of a return message.

Specifically, the application provides two possible ways for the network device to determine whether the terminal device can perform the indication information type switching according to the switching request.

In a possible implementation manner, for application scenarios with different indication information used by different terminal devices in the same cell, after receiving a handover request of a terminal device, a network device only determines whether the terminal device can perform handover. The network device may determine whether the type of the indication information of the terminal device is switchable by judging whether the switching request and/or other information satisfy the condition for switching the type of the indication information of the terminal device. For example: and if the terminal equipment determines that the type of the indication information needs to be switched to the WUS according to the mode in the embodiment, sending a switching request to the network equipment. After the network device receives the switching request sent by the terminal device, the network device considers the available resources of the network side according to the switching request of the terminal device, if the network resource overhead is large at the moment, the network device judges that the overhead of the network resources is further increased after the indication information of the terminal device is switched to the WUS, the network resource condition is influenced, and judges that the switching request of the terminal device cannot be corresponding, namely S101 is not executed; and if the network resource overhead is small at the moment and the indication information of the terminal equipment can be allowed to be switched to the WUS, determining that the type of the indication information of the terminal equipment can be switched.

In another possible implementation manner, the indication information types used by different terminal devices in the same cell need to keep the same application scenario, and after receiving a handover request of a terminal device, a network device needs to consider all terminal devices in the cell. Therefore, the network device judges the number of switching requests sent by all terminal devices in the cell where the terminal device is located, and if the number is larger than a preset threshold value, the network device determines that the type of the indication information of the terminal device can be switched; if the number is smaller than the preset threshold value, the network equipment determines that the type of the indication information of the terminal equipment cannot be switched. Specifically, for an application scenario in which indication information used by different terminal devices in the same cell is the same, the network device needs to determine whether to uniformly switch the indication information used by all the terminals in the cell from the perspective of the whole cell. For example: when a network device receives a switching request of a terminal device in a cell, the network device judges whether the switching request sent by other terminal devices is received within a certain time range. If the switching requests sent by other 4 terminal devices are received within a certain time range of receiving the switching request of the terminal device, and the number of the terminal devices requesting the type switching of the indication information is over half, determining to switch the indication information of all the terminal devices in the cell. If the network device does not receive the switching request sent by other terminal devices in the cell within a certain time range after receiving the switching request of one terminal device in the cell, the network device does not process the switching request sent by the terminal, and in a possible embodiment, the network device can also inform the terminal device that the switching request is not processed in a feedback information mode.

Fig. 7 is a flowchart illustrating an embodiment of an indication information communication method according to the present application. The embodiment shown in fig. 7 shows a manner that the network device determines whether to switch the type of the indication information according to the switching criterion, and sends a switching command to the terminal device when the switching is needed. As shown in fig. 7, the present embodiment further includes, before S101, on the basis of the embodiment shown in fig. 5:

s301: the network judges that the service density between the terminal equipment and the network equipment meets the switching criterion; the network device in S101 generates a handover command is executed. Further, if the network device determines that the traffic density between the terminal device and the network device does not satisfy the handover criterion, S101 is not performed. That is, when the network device determines that the traffic density between the terminal device and the network device does not satisfy the handover criterion, the type of the indication information of the existing terminal device is kept from being handed over.

Alternatively, here, the determination of the traffic density between the network device and the terminal device in S301 may also be configured to be performed periodically, and the network device performs the determination in S301 every fixed time interval.

Optionally, the switching criterion that the network device determines whether the traffic density meets may adopt the switching criterion that may be used in the embodiment shown in fig. 6, and the specific determination is the same, and is not described again. Alternatively, the switching criteria may be different from those in the embodiment shown in fig. 6.

It should be noted that, for the form of the handover command generated in S101 when the network device determines that the type of the indication information of the terminal device needs to be switched in the embodiment shown in fig. 7, the form of the two handover commands may be the same or different from the form of the handover command generated in S101 after the network device receives the handover request sent by the terminal device in the embodiment shown in fig. 6.

For example: if the network device determines that the type of the indication information of the terminal device needs to be switched in the embodiment shown in fig. 7, since the terminal device cannot determine whether the type of the indication information needs to be switched and how to switch the type of the indication information, a switching command sent by the network device to the terminal device needs to include a specific type indicated by the network device, and the terminal device needs to switch the type of the indication information according to the specific type.

Another example is: in the embodiment shown in fig. 6, when the terminal device determines that the type of the indication information needs to be switched, a switching request is sent to the network device, and the network device determines whether the terminal device can perform switching according to the switching request. Therefore, although the terminal device has determined that its instruction information needs to be switched through the judgment of S201, it needs to transmit a switching request to let the network device judge whether the instruction information of the terminal device can be switched. And if the network equipment judges that the indication information of the terminal equipment can be switched, generating a switching command and sending the switching command to the terminal equipment. In this case, the handover command may include neither the type of the indication information nor the type of the indication information. In the embodiment of fig. 6, when the handover command does not include the type of the indication information, the terminal device can determine, according to the handover command, that the type of the indication information can be switched to the type of the indication information determined by the terminal device in S201 after receiving the handover command; or after receiving the switching command, the terminal device determines the type of the indication information to be switched according to the switching command, the type of the currently monitored indication information and the switching relationship, wherein the switching relationship may also be that the terminal device is configured in advance and stored in the terminal device, or the switching relationship may also be carried in the switching command and sent to the terminal device by the network device in real time. In the embodiment of fig. 6, when the handover command includes the type of the indication information, the type of the indication information in the handover command may be the same as or different from the type requested by the terminal device, and after receiving the handover command, the terminal device performs handover according to the type of the indication information in the handover command. The form of the handover command in the above embodiments is an example, and the specific form of the handover command is not limited in the present application.

In summary, in the indication information communication method provided in this embodiment, the network device or the terminal device can determine whether to switch the type of the indication information according to the traffic density therebetween, and if it is determined that the type of the indication information needs to be determined according to the determination criterion, the network device sends a switching command to the terminal device, so that the terminal device completes switching of the type of the indication information, and thus, when the switching condition of the indication information is satisfied, according to the switching command sent by the network device to the terminal device, the network device and the terminal device can communicate with each other using different types of indication information, thereby satisfying dynamic changes of different usage scenarios and traffic of the terminal device, improving switching flexibility of the indication information of the terminal, and further reducing power consumption and communication overhead of the terminal device.
