Description

Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a communication method and a communication device. Background Art

[0002] In order to reduce the power consumption of terminal devices, the 3rd generation partnership project (3GPP) release 18 (rel-18) protocol stipulates that the terminal device monitors the low-power wake-up signal (LP-WUS) through a low-power wake-up radio / wake-up receiver (LP-WUR) to determine whether to wake up the main receiver of the terminal device.

[0003] The terminal device can determine whether to wake up the WUR based on, for example, channel conditions, but the network equipment currently has no relevant technology to support it. Summary of the invention

[0004] The embodiments of the present application provide a communication method and a communication device, which can avoid the misalignment between the working mode of the terminal device itself and the working mode determined by the first network device, but still avoid the waste of resources caused by using misaligned receivers for communication.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] In a first aspect, a transmission method is provided, which can be executed by a terminal device, or by a component of the terminal device, such as a processor, a chip, or a chip system of the terminal device, or by a logic module or software that can realize all or part of the functions of the terminal device. Taking the method that can be executed by the terminal device as an example, the method includes: the terminal device determines first indication information, the first indication information is used to indicate the working mode of the terminal device, the working mode is a first mode or a second mode, in the first mode, the terminal device communicates with the first network device through the first receiver, and in the second mode, the terminal device communicates with the first network device through the second receiver, and the power of the first receiver is less than the power of the second receiver; the terminal device sends the first indication information to the first network device.

[0007] In the communication method provided in the embodiment of the present application, a terminal device sends first indication information for indicating the working mode of the terminal device to a first network device. The first network device can communicate with the terminal device through a corresponding receiver based on the received first indication information, so that the working mode of the terminal device itself is aligned with the working mode of the terminal device determined by the first network device based on the first indication information. Then, the first network device and the terminal device can communicate using the corresponding receiver, avoiding the misalignment between the working mode of the terminal device itself and the working mode determined by the first network device, but still using misaligned receivers for communication and causing waste of resources.

[0008] In the embodiment of the present application, the working mode of the terminal device is determined according to a first preset condition, wherein the first preset condition includes at least one of the following: whether the terminal device is within the coverage of a first signal, wherein the first signal is a signal received by the terminal device through a first receiver; whether the second receiver of the terminal device turns on a first measurement, wherein the first measurement is a measurement of cell granularity; the terminal device receives second indication information from a first network device, wherein the second indication information is used to indicate that the terminal device determines the working mode as a second mode; the terminal device receives third indication information from the first network device, wherein the third indication information is used to indicate that the terminal device determines the working mode as a first mode. After the terminal device determines the working mode according to the first preset condition, the working mode can be determined according to the first preset condition, and the corresponding receiver can be used to communicate with the first network device. Further, the terminal device can send indication information indicating the working mode determined according to the first preset condition to the first network device, and the first network device can communicate with the terminal device according to the first indication information using the corresponding receiver, so that the working modes of the first network device and the terminal device are aligned.

[0009] In a possible implementation, when the terminal device is not within the coverage of the first signal, the working mode of the terminal device is the second mode; or, when the terminal device is within the coverage of the first signal, the working mode of the terminal device is the first mode, so that the terminal device can determine the working mode according to whether the terminal device is within the coverage of the first signal.

[0010] In a possible implementation, the coverage of the first signal is determined by the signal quality of the first signal; wherein the terminal device is within the coverage of the first signal, including: the measured value of the signal quality of the first signal received by the terminal device is greater than or equal to the first threshold; or the terminal device is not within the coverage of the first signal, including: the measured value of the signal quality of the first signal is less than the first threshold, or the first signal is not received. The terminal device can determine whether it is within the coverage of the first signal according to the measured value of the received signal quality or whether the terminal device is received.

[0011] In a possible implementation, the measured value of the signal quality of the first signal is greater than or equal to the first threshold, including: the measured values ​​of the signal quality of the first signal in the first time length are all greater than or equal to the first threshold, or the average value of the measured values ​​of the signal quality of the first signal in the first time length is greater than or equal to the first threshold; the measured value of the signal quality of the first signal is less than the first threshold, including: the measured values ​​of the signal quality of the first signal in the first time length are all less than the first threshold, or the average value of the measured values ​​of the signal quality of the first signal in the first time length is less than the first threshold. By setting the first time length, the waste of resources caused by the frequent switching of the working mode of the terminal device can be avoided. For example, if the measured value of the signal quality of the first signal received by the terminal device is erroneous due to the obstruction of an obstacle, causing the terminal device to switch the working mode, it will cause a waste of resources due to the switching of the working mode.

[0012] In a possible implementation, the failure to receive the first signal includes: the failure to receive the first signal within a second time period. By setting the second time period, it is possible to avoid waste of resources caused by frequent switching of working modes of the terminal device. For example, if the terminal device fails to receive the first signal due to obstruction by an obstacle, causing the terminal device to switch working modes, it will result in waste of resources caused by switching working modes.

[0013] In an embodiment of the present application, the method further includes: the terminal device receives first configuration information, wherein the first configuration information is used to configure the first signal, and the first configuration information includes at least one of a first duration, a first threshold, and a second duration. After the terminal device obtains the first configuration information, it can further determine the relationship between the measured value of the signal quality of the first signal and the first threshold or the second threshold, thereby implementing the solution described in the embodiment of the present application.

[0014] In a possible implementation, when the second receiver of the terminal device starts the first measurement, the working mode of the terminal device is the second mode; or, when the second receiver of the terminal device does not start the first measurement, the working mode of the terminal device is the first mode. The terminal device determines the working mode of the terminal device according to whether the second receiver starts the first measurement.

[0015] In the embodiment of the present application, the first measurement includes at least one of the following: serving cell measurement, neighboring cell same-frequency measurement, and neighboring cell different-frequency measurement.

The terminal device measures the first signal, and then when the terminal device determines that the measured value of the signal quality of the first signal is greater than or equal to the second threshold, the terminal device sends the fourth indication information indicating that the measured value of the signal quality of the first signal is greater than or equal to the second threshold to the first network device. Further, the first network device can determine the second indication information based on the fourth indication information of the terminal device.

[0017] In a possible implementation, the measured value of the signal quality of the first signal is greater than or equal to the second threshold, including: the measured values ​​of the signal quality of the first signal within the third time period are all greater than or equal to the second threshold, or the average value of the measured values ​​of the signal quality of the first signal within the third time period is greater than or equal to the second threshold. The third time period is set so that the terminal device sends the fourth indication information to the first network device only when it determines within a certain period of time that the measured value of the signal quality of the first signal is greater than or equal to the second threshold, thereby avoiding waste of resources caused by frequent sending of indication information.

[0018] In a possible implementation, the fourth indication information includes the measured value of the signal quality of the first signal within the third time period; or, the fourth indication information includes the first identifier, and the first identifier is used to characterize that the measured value of the signal quality of the first signal is greater than or equal to the second threshold value within the third time period. The fourth indication information includes the measured value of the signal quality of the first signal within the third time period, which allows the first network device to directly know the measured value of the signal quality of the first signal; the first indication information includes the first identifier, which allows the first network device to know through a first identifier that the measured value of the signal quality of the first signal is greater than or equal to the second threshold value within the third time period, saving resources for sending the measurement value.

[0019] In the embodiment of the present application, before the terminal device receives the second indication information, the method further includes: when the measured value of the signal quality of the received first signal is less than the second threshold, the terminal device sends fifth indication information, and the fifth indication information is used to indicate that the measured value of the signal quality of the first signal is less than the second threshold. The terminal device measures the first signal, and when the terminal device determines that the measured value of the signal quality of the first signal is less than the second threshold, the terminal device sends the fifth indication information indicating that the measured value of the signal quality of the first signal is less than the second threshold to the first network device. Further, the first network device can determine the third indication information based on the fifth indication information of the terminal device.

[0020] In a possible implementation, the measured value of the signal quality of the first signal is less than the second threshold, including: the measured values ​​of the signal quality of the first signal are all less than the second threshold within the third time period, or the average value of the measured values ​​of the signal quality of the first signal within the third time period is less than the second threshold. The third time period is set so that the terminal device sends the fifth indication information to the first network device only when it determines within a certain period of time that the measured value of the signal quality of the first signal is less than the second threshold, thereby avoiding waste of resources caused by frequent sending of indication information.

[0021] In a possible implementation, the fifth indication information includes the measured value of the signal quality of the first signal within the third time period; or, the fifth indication information includes a second identifier, and the second identifier is used to characterize that the measured value of the signal quality of the first signal is less than the second threshold value within the third time period. The fifth indication information includes the measured value of the signal quality of the first signal within the third time period, which allows the first network device to directly know the measured value of the signal quality of the first signal; the first indication information includes the second identifier, which allows the first network device to know through a second identifier that the measured value of the signal quality of the first signal is less than the second threshold value within the third time period, saving resources for sending the measured value.

[0022] In an embodiment of the present application, the first signal includes at least one of the following: a low-power wake-up signal, a low-power synchronization signal, a low-power reference signal, and a synchronization signal block.

[0024] In the embodiment of the present application, the terminal device is in a non-connected state, and the first indication information is included in the restore connection establishment message, so that the terminal device can also send the first indication information through the restore connection establishment message in the non-connected state.

[0025] In an embodiment of the present application, the method further includes: the terminal device receives a first cell list from a second network device, wherein the second network device is a network device to release the network connection of the terminal device, and the network device corresponding to the cell indicated by the first cell list is a network device with which the terminal device communicates using the first receiver; when the terminal device resides in the cell indicated by the first cell list, the terminal device uses the first receiver to communicate with the corresponding network device. By receiving the first cell list from the second network device, the terminal device can obtain multiple network devices corresponding to the cells in the first cell list at one time. When the terminal device resides in a certain cell, it only needs to know whether the cell is a cell in the first cell list to determine whether to use the first receiver to communicate with the network device corresponding to the cell. There is no need to determine the working mode according to the first preset condition, and the implementation complexity is lower. When the first preset condition corresponds to receiving indication information, resources used for indication are saved.

[0026] In an embodiment of the present application, the method further includes: the terminal device receives sixth indication information from the first network device, the sixth indication information instructing the terminal device to communicate with the first network device through the first receiver, and the first network device is a network device to release the network connection of the terminal device. The terminal device can determine the working mode of the terminal device through the sixth indication information instructing the terminal device to communicate with the first network device through the first receiver, thereby reducing the complexity and avoiding the additional resource overhead caused by the terminal device itself determining the working mode.

[0027] In an embodiment of the present application, the method further includes: the terminal device receives first feedback information from the first network device, the first feedback information being used to instruct the first network device to communicate with the terminal device according to the first indication information.

[0072] To facilitate understanding of the technical solutions provided by the embodiments of the present application, a brief introduction to the relevant technologies of the embodiments of the present application is first given. The brief introduction is as follows:

[0073] 1. Radio resource control (RRC) status.

[0074] In the new radio (NR) system, the RRC state may include an RRC idle (RRC_IDLE) state, an RRC inactive (RRC_INACTIVE) state, and an RRC connected (RRC_CONNECTED) state. In the case where the terminal device has no signaling and / or service data to receive or send, the terminal device may enter an idle state or an inactive state to reduce the power consumption of the terminal device.

[0075] The RRC_IDLE state, also known as the idle state, refers to the state in which the terminal device completes the residency in the cell but does not perform the random access process. The terminal device usually enters the idle state after being powered on or after the RRC connection is released. When the terminal device is in the idle state, the air interface connection between the terminal device and the network device is disconnected, the context information is no longer saved, the terminal device only receives limited downlink information, and does not send uplink information.

[0076] It should be understood that uplink information may refer to information sent by a terminal device to a network device, and downlink information may refer to information sent by a network device to a terminal device. Among them, limited downlink information may include downlink synchronization information required for a terminal device to complete its stay in a cell, information contained in a master information block (MIB), and information contained in a system information block (SIB) 1 (or remaining minimum system information (RMSI)), etc. For details, please refer to the description of the relevant 3GPP standard protocols, which will not be repeated here.

[0077] The RRC_CONNECTED state, also known as the connected state, corresponds to the idle state. The connected state refers to the state in which the terminal device is in after completing the random access process and before releasing the RRC connection. When the terminal device is in the connected state, it establishes an air interface connection with the network device and communicates with the network device based on the air interface connection. When the terminal device is in the idle state, after the terminal device completes the random access process, the state of the terminal device migrates to the connected state. When the terminal device is in the connected state, after completing the RRC connection release, the state of the terminal device migrates to the idle state.

[0078] The RRC_INACTIVE state can also be called the inactive state. The inactive state is a state between the connected state and the idle state. For the terminal device in the inactive state, the user plane bearer of the air interface has been suspended, and the user plane bearer and control plane bearer between the network device and the core network (CN) are still maintained. When the terminal device initiates a call or service request, it is necessary to activate the user plane bearer of the air interface, and reuse the existing user plane bearer and control plane bearer between the network device and the CN. It can be understood that when the terminal device is in the inactive state, the air interface connection between the terminal device and the network device is disconnected, but the context information continues to be saved. When the terminal device enters the connected state from the inactive state, based on the saved context information, the terminal device can quickly restore to the connected state.

[0079] 2. Main receiver.

[0080] The main receiver (MR) receives the signal used in the existing network. The status of the main receiver may include:

[0081] On state, off state, different degrees of sleep state (deep sleep state, ultra-deep sleep state). The energy and time required to switch to the on state in different states are different.

[0108] Figure 3 It is an example of a communication method provided in an embodiment of the present application. The method is illustrated by taking the interaction between a terminal device and a first network device as an example. Of course, the subject that executes the action of the terminal device in the method can also be a device / module in the terminal device, such as a chip, a processor, a processing unit, etc. in the terminal device; the subject that executes the action of the first network device in the method can also be a device / module in the first network device, such as a chip, a processor, a processing unit, etc. in the network device, and the embodiment of the present application does not specifically limit this.

For example, the processing performed by the first network device can be divided into executions by at least one of CU, DU and RU. Exemplary, such as Figure 3 The method 300 includes:

[0109] S310, the terminal device determines the first indication information.

[0110] S320, the terminal device sends first indication information to the first network device. Correspondingly, the first network device receives the first indication information from the terminal device.

[0111] S330, the first network device communicates with the terminal device according to the first indication information.

[0112] The above steps are introduced below.

[0113] For the above step S310:

[0114] In the embodiment of the present application, the first indication information is used to indicate the working mode of the terminal device. The working mode of the terminal device is the first mode or the second mode. In the first mode, the terminal device communicates with the first network device through the first receiver; in the second mode, the terminal device communicates with the first network device through the second receiver. In the embodiment of the present application, the power of the first receiver is less than the power of the second receiver.

[0115] In an embodiment of the present application, the first mode and the second mode can be indicated by different values ​​of the first indication information. Exemplarily, the first indication information can be 1 bit. If the first indication information is "0", it can indicate that the working mode of the terminal device is the first mode, and if the first indication information is "1", it can indicate that the working mode of the terminal device is the second mode; or, if the first indication information is "1", it can indicate that the working mode of the terminal device is the first mode, and if the first indication information is "0", it can indicate that the working mode of the terminal device is the second mode. This embodiment of the present application does not limit this.

[0116] Alternatively, one of the first mode and the second mode may be indicated by sending the first indication information, and the other mode may be indicated by not sending the first indication information. Exemplarily, sending the first indication information may indicate that the working mode of the terminal device is the first mode, and not sending the first indication information may indicate that the working mode of the terminal device is the second mode; or not sending the first indication information may indicate that the working mode of the terminal device is the first mode, and sending the first indication information may indicate that the working mode of the terminal device is the second mode, and the embodiments of the present application do not limit this.

[0117] Alternatively, the first mode and the second mode may be indicated by different ways of sending the first indication information, for example, by carrying the first indication information through different messages. Exemplarily, sending the first indication information in a first way may indicate that the working mode of the terminal device is the first mode, and sending the first indication information in a second way may indicate that the working mode of the terminal device is the second mode. Specifically, for example, the first indication information is carried in the first message, which may indicate that the working mode of the terminal device is the first mode, and the first indication information is carried in the second message, which may indicate that the working mode of the terminal device is the second mode.

[0118] In the embodiment of the present application, the working mode of the terminal device is the first mode or the second mode, which can be understood as: the working mode of the terminal device includes the first mode and the second mode, wherein, at a certain moment, the working mode of the terminal device is one of the first mode and the second mode, or the working mode of the terminal device is the first mode and the second mode, and the embodiment of the present application does not limit this.

[0119] Optionally, in the embodiment of the present application, when the terminal device communicates with the first network device through the first receiver in the first mode:

[0120] The second receiver may be in an off state; or, the second receiver may be in a sleep state; or, the second receiver may be in an on state.

[0121] The sleep state in the embodiment of the present application may also be referred to as a hibernation state or a standby state, etc. The embodiment of the present application does not specifically limit the name of this state.

[0122] When the second receiver is in a closed state or a sleep state, the second receiver of the terminal device does not communicate with the first network device.

[0123] When the second receiver is turned on, the second receiver of the terminal device can communicate with the first network device, that is, in the first mode, when the second receiver is turned on, the terminal device can communicate with the first network device through the first receiver, and the terminal device can also communicate with the first network device through the second receiver.

[0124] In an embodiment of the present application, in the first mode, when the terminal device communicates with the first network device through the first receiver, the second receiver is in an off state, which can save the energy consumption of the second receiver; the second receiver is in a sleep state, which can enable the second receiver to resume the on state in a shorter time and save the power consumption of the on state.

[0125] In a possible implementation, the second receiver in the embodiment of the present application may be the main receiver in the above-mentioned related introduction 2, and the sleep state of the second receiver may be the sleep state of different degrees in the above-mentioned related introduction 2, which will not be repeated here.

[0126] Optionally, in the embodiment of the present application, when the terminal device communicates with the first network device through the second receiver in the second mode:

[0127] The first receiver may be in an off state; or, the first receiver may be in a sleep state; or, the first receiver may be in an on state.

[0128] When the first receiver is in a closed state or a sleep state, the first receiver of the terminal device does not communicate with the first network device.

[0129] When the first receiver is turned on, the first receiver of the terminal device can communicate with the first network device, that is, in the second mode, when the first receiver is turned on, the terminal device can communicate with the first network device through the second receiver, and the terminal device can also communicate with the first network device through the first receiver.

[0130] In an embodiment of the present application, in the second mode, when the terminal device communicates with the first network device through the second receiver, the first receiver is in an off state, which can save the energy consumption of the second receiver; the first receiver is in a sleep state, which can enable the first receiver to resume the on state in a shorter time and save the power consumption of the on state.

[0131] In a possible implementation, the sleep state of the first receiver in the embodiment of the present application can be a sleep state of different degrees. The energy and time required to switch to the on state in different sleep states are different, and the present application does not limit this.

[0132] It should be noted that in the embodiment of the present application, the sleep state of the first receiver can have the same parameters as the different degrees of sleep state of the main receiver in the related technology 2, the sleep state of the first receiver can also be a newly defined sleep state of different degrees, or the sleep state of the first receiver can also be called a dormant state, a standby state, etc., and the embodiment of the present application does not limit this.

[0133] Optionally, in an embodiment of the present application, the terminal device communicates with the first network device, and the terminal device may receive paging from the first network device; or, the terminal device measures a signal sent by the first network device; or, the terminal device sends information to the first network device; or, the terminal device receives information from the first network device, and the present application does not limit this.

[0134] Optionally, in an embodiment of the present application, the power of the first receiver is less than the power of the second receiver, which can be understood as the complexity of the first receiver is lower than the complexity of the second receiver; or, the power consumption of the first receiver is lower than that of the second receiver; or, the processing capability of the first receiver is lower than that of the second receiver, and the processing capability may be, for example, demodulation capability, or computing capability, etc., which is not limited in the embodiment of the present application.

[0135] In a possible implementation, in an embodiment of the present application, the working mode of the terminal device is determined according to a first preset condition, wherein the first preset condition may include at least one of the following:

[0136] One of the first preset conditions: whether the terminal device is within the coverage of a first signal, wherein the first signal is a signal received by the terminal device through a first receiver.

[0137] The second first preset condition: whether the first receiver of the terminal device starts the first measurement.

[0138] The third of the first preset condition: the terminal device receives second indication information from the first network device, and the second indication information is used to instruct the terminal device to determine the working mode as the second mode.

[0139] The fourth of the first preset condition: the terminal device receives third indication information from the first network device, and the third indication information is used to instruct the terminal device to determine the working mode as the first mode.

[0140] The above four first preset conditions will be introduced in detail below. It should be understood that the working mode of the terminal device can also be determined by other conditions. Four preset conditions are proposed in the embodiment of the present application, but other conditions that can determine the working mode of the terminal device are not limited.

[0141] Optionally, the working mode of the terminal device indicated by the first indication information in the embodiment of the present application can be determined after switching the working mode according to the first preset condition. Switching the working mode can be understood as follows: for example, the working mode of the terminal device is the first mode, and after switching the working mode, the working mode of the terminal device is the second mode; for another example, the working mode of the terminal device is the second mode, and after switching the working mode, it is the first mode.

[0142] For one of the first preset conditions, in an embodiment of the present application, the first signal may be a low-power wake-up signal (LP-WUS), a low-power synchronization signal (LP-SS), a low-power reference signal (LP-RS), or a synchronization signal block (SSB), and the embodiment of the present application does not limit this. Exemplarily, the first signal may be a signal that can be received by the first receiver, and the decoding complexity or receiving power consumption of the first signal is low; Exemplarily, the first signal may be a signal that can be received by the second receiver, and the receiving length of the first signal is limited. The embodiment of the present application does not limit whether the first signal can be received by the first receiver or the second receiver, and does not limit the decoding complexity, receiving power consumption, and receiving signal length of the first signal.

[0143] In one possible implementation, in an embodiment of the present application, when the terminal device is not within the coverage of the first signal, the operating mode of the terminal device is the second mode; or, when the terminal device is within the coverage of the first signal, the operating mode of the terminal device is the first mode.

[0144] In a possible implementation manner, the coverage range of the first signal is determined by whether the terminal device can receive the first signal.

[0145] In another possible implementation, the coverage of the first signal is determined by the signal quality of the first signal. The terminal device is within the coverage of the first signal, including: the measured value of the signal quality of the first signal received by the terminal device is greater than or equal to the first threshold; or, the terminal device is not within the coverage of the first signal, including: the measured value of the signal quality of the first signal is less than the first threshold. Optionally, in an embodiment of the present application, the terminal device measures the received first signal for the first receiver of the terminal device to measure the first signal, or for the second receiver of the terminal device to measure the first signal. In an embodiment of the present application, the format of the measurement value obtained by the first receiver of the terminal device to measure the first signal may be different from the format of the measurement value obtained by the second receiver of the terminal device to measure the first signal. Optionally, the format of the measurement value measured by the first receiver of the terminal device and the format of the measurement value measured by the second receiver of the terminal device can be unified by the same mathematical rule, and the embodiment of the present application does not limit the unified or non-unified format of the measurement value.

[0146] In the embodiment of the present application, when the measured value of the signal quality of the first signal is greater than or equal to the first threshold, the terminal device can determine that it is within the coverage of the first signal; when the measured value of the signal quality of the first signal is less than the first threshold, the terminal device can determine that it is not within the coverage of the first signal. For example, the first threshold is 5dB, when the terminal device measures the received first signal, and the measured value is 6dB, it can be considered that the terminal device is within the coverage of the first signal; when the terminal device measures the received first signal, and the measured value is 4dB, it can be considered that the terminal device is not within the coverage of the first signal.

[0147] Optionally, in an embodiment of the present application, when determining whether the terminal device is within the coverage of the first signal, a duration factor needs to be considered.

[0148] For example, within the first time period, the measured values ​​of the signal quality of the first signal are greater than or equal to the first threshold, and the terminal device can determine that it is within the coverage range of the first signal. For another example, within the first time period, the measured values ​​of the signal quality of the first signal are less than the first threshold, and the terminal device can determine that it is not within the coverage range of the first signal.

[0149] Or, for example, within a first time period, if the average value of the measured values ​​of the signal quality of the first signal is greater than or equal to a first threshold, the terminal device can determine that it is within the coverage range of the first signal. For another example, within the first time period, if the average value of the measured values ​​of the signal quality of the first signal is less than the first threshold, the terminal device can determine that it is not within the coverage range of the first signal.

[0150] Or, for example, within the first time length, the measured value of the signal quality of the first signal is allowed to have N errors. For example, if the measured value of the signal quality of the first signal is less than the first threshold for less than three times, it can also be considered that the measured value of the signal quality of the first signal within the first time length is greater than or equal to the first threshold; or, for example, if the measured value of the signal quality of the first signal is greater than or equal to the first threshold for less than three times, it can also be considered that the measured value of the signal quality of the first signal within the first time length is less than the first threshold.

[0151] In an embodiment of the present application, the measurement value of the signal quality of the first signal within the first time length may be a measurement value of the signal quality of continuously measuring the first signal within the first time length, or may be a measurement value of multiple measurements of the first signal within the first time length. The embodiment of the present application does not limit the number of measurements of the multiple measurements.

[0152] The embodiment of the present application does not specifically limit how to determine the relationship between the measured value of the signal quality of the first signal and the first threshold.

[0153] In another possible implementation, the coverage of the first signal is determined by whether the terminal device receives the first signal. The terminal device is not within the coverage of the first signal, including: the terminal device does not receive the first signal. In other words, the terminal device does not receive the first signal, and the terminal device can determine that it is not within the coverage of the first signal.

[0154] In the embodiment of the present application, the terminal device receives the first signal, including: the terminal device successfully receives the first signal, or the terminal device receives the first signal. Exemplarily, the terminal device successfully receives the first signal means that the terminal device receives the first signal and decodes it successfully; the terminal device receives the first signal means that the terminal device receives the first signal but does not necessarily decode it successfully. It should be understood that the coverage of the terminal device is determined by the terminal device receiving the first signal, and the coverage of the terminal device can be determined by the terminal device successfully receiving the first signal, or it can be determined by the terminal device receiving the first signal, and the present application does not limit this.

[0155] Optionally, in an embodiment of the present application, when the terminal device determines that it has not received the first signal, a duration factor needs to be considered.

[0156] For example, the terminal device does not receive the first signal within the second time period and determines that it is not within the coverage of the first signal.

[0157] In the embodiment of the present application, by setting the first duration and the second duration, it is possible to avoid waste of resources caused by frequent switching of the working mode of the terminal device. For example, if the measurement value of the signal quality of the first signal received by the terminal device is erroneous due to the obstruction of an obstacle, or the terminal device fails to receive the first signal, causing the terminal device to switch the working mode, it will lead to waste of resources caused by switching the working mode.

[0158] For the second of the first preset conditions, the first measurement is a measurement of cell granularity, or the first measurement is a measurement of frequency point granularity, wherein the first measurement can be a service cell measurement, a neighboring cell same-frequency measurement, a neighboring cell different-frequency measurement, etc., or the first measurement can be a measurement of multiple cells corresponding to one frequency point, and the embodiments of the present application are not limited to this.

[0159] In an embodiment of the present application, when the second receiver of the terminal device starts the first measurement, the working mode of the terminal device is the second mode; or, when the second receiver of the terminal device does not start the first measurement, the working mode of the terminal device is the first mode.

[0160] In a possible implementation, the first receiver of the terminal device does not support the first measurement, and when the terminal device needs to perform the first measurement, the working mode of the terminal device is the second mode. The first receiver does not support the first measurement may be that the measured value of the signal quality of the first signal is less than the start threshold for starting the first measurement, or the first receiver does not support the first measurement may be that the first receiver cannot complete the first measurement under the condition of power consumption or complexity, etc., which is not limited in the embodiments of the present application.

[0161] Exemplarily, the working mode of the terminal device is the first mode, and the first receiver can perform service cell measurement; the working mode of the terminal device is the second mode, and the second receiver can perform neighboring cell same-frequency measurement or neighboring cell different-frequency measurement.

[0162] For the third of the first preset conditions, the terminal device receives second indication information from the first network device, and the second indication information is used to instruct the terminal device to determine the working mode as the second mode.

[0163] In an embodiment of the present application, the first mode and the second mode can be indicated by different values ​​of the second indication information. Exemplarily, the second indication information can be 1 bit. If the second indication information is "0", it can indicate that the working mode of the terminal device is the first mode, and if the second indication information is "1", it can indicate that the working mode of the terminal device is the second mode; or, if the second indication information is "1", it can indicate that the working mode of the terminal device is the first mode, and if the first indication information is "0", it can indicate that the working mode of the terminal device is the second mode, and the embodiment of the present application does not limit this.

[0164] Alternatively, one of the first mode and the second mode may be indicated by sending the second indication information, and the other mode may be indicated by not sending the second indication information. Exemplarily, sending the second indication information may indicate that the working mode of the terminal device is the first mode, and not sending the second indication information may indicate that the working mode of the terminal device is the second mode; or not sending the second indication information may indicate that the working mode of the terminal device is the first mode, and sending the second indication information may indicate that the working mode of the terminal device is the second mode, and the embodiments of the present application do not limit this.

[0165] Alternatively, the first mode and the second mode may be indicated by different ways of sending the second indication information, for example, the second indication information may be carried by different messages. Exemplarily, sending the second indication information in a first way may indicate that the working mode of the terminal device is the first mode, and sending the second indication information in a second way may indicate that the working mode of the terminal device is the second mode. Specifically, for example, the second indication information is carried in the first message, which may indicate that the working mode of the terminal device is the first mode, and the second indication information is carried in the second message, which may indicate that the working mode of the terminal device is the second mode.

[0166] In a possible implementation of the embodiment of the present application, the second indication information is determined by fifth indication information sent by the terminal device to the first network device, and the fifth indication information is used to indicate that the measured value of the signal quality of the first signal is less than the second threshold. The fifth indication information is sent by the terminal device to the first network device when the measured value of the signal quality of the received first signal is less than the second threshold.

[0167] In an embodiment of the present application, the measured value of the signal quality of the first signal is less than the second threshold value, which may be that within the third time period, the measured values ​​of the signal quality of the first signal are all less than the second threshold value, or, within the third time period, the average value of the measured values ​​of the signal quality of the first signal is less than the second threshold value, or, within the third time period, the measured value of the signal quality of the first signal is allowed to have M errors, for example, the measured value of the signal quality of the first signal is greater than or equal to the second threshold value three times, and it can also be considered that the measured value of the signal quality of the first signal within the third time period is less than the second threshold value, which is not limited to the embodiment of the present application.

[0168] In the embodiment of the present application, the fifth indication information may include a measured value of the signal quality of the first signal within the third duration, or the fifth indication information may include a second identifier, and the second identifier is used to indicate that the signal quality of the first signal is less than the second threshold. In the case where the fifth indication information includes the measured value of the signal quality of the first signal within the third duration, the first network device may determine that the measured value of the signal quality of the first signal is less than the second threshold based on the measured value of the signal quality of the first signal within the third duration.

[0169] In another possible implementation manner of the embodiment of the present application, the second indication information is determined based on business requirements, quality of service (QoS) requirements, or requirements of specific scenarios, etc., and the embodiment of the present application is not limited to this.

[0170] For the fourth of the first preset conditions, the terminal device receives third indication information from the first network device, and the third indication information is used to instruct the terminal device to determine the working mode as the first mode.

[0171] In an embodiment of the present application, the first mode and the second mode can be indicated by different values ​​of the third indication information. Exemplarily, the third indication information can be 1 bit. If the third indication information is "0", it can indicate that the working mode of the terminal device is the first mode, and if the third indication information is "1", it can indicate that the working mode of the terminal device is the second mode; or, if the third indication information is "1", it can indicate that the working mode of the terminal device is the first mode, and if the first indication information is "0", it can indicate that the working mode of the terminal device is the second mode, which is not limited in the embodiment of the present application.

[0172] Alternatively, one of the first mode and the second mode may be indicated by sending the third indication information, and the other mode may be indicated by not sending the third indication information. Exemplarily, sending the third indication information may indicate that the working mode of the terminal device is the first mode, and not sending the third indication information may indicate that the working mode of the terminal device is the second mode; or not sending the third indication information may indicate that the working mode of the terminal device is the first mode, and sending the third indication information may indicate that the working mode of the terminal device is the second mode, and the embodiments of the present application do not limit this.

[0173] Alternatively, the first mode and the second mode may be indicated by different ways of sending the third indication information, for example, the third indication information may be carried by different messages. Exemplarily, sending the third indication information in a first way may indicate that the working mode of the terminal device is the first mode, and sending the third indication information in a second way may indicate that the working mode of the terminal device is the second mode. Specifically, for example, the third indication information is carried in the first message, which may indicate that the working mode of the terminal device is the first mode, and the third indication information is carried in the second message, which may indicate that the working mode of the terminal device is the second mode.

[0174] In a possible implementation of the embodiment of the present application, the third indication information is determined by fourth indication information sent by the terminal device to the first network device, and the fourth indication information is used to indicate that the measured value of the signal quality of the first signal is greater than or equal to the second threshold. The fourth indication information is sent by the terminal device to the first network device when the measured value of the signal quality of the received first signal is greater than or equal to the second threshold.

[0175] In an embodiment of the present application, the measured value of the signal quality of the first signal is greater than or equal to the second threshold value. It can be that within the third time period, the measured values ​​of the signal quality of the first signal are all greater than or equal to the second threshold value, or, the average value of the measured values ​​of the signal quality of the first signal within the third time period is greater than or equal to the second threshold value, or, within the third time period, the measured value of the signal quality of the first signal is allowed to have M errors, for example, the measured value of the signal quality of the first signal is less than the second threshold value three times, and it can also be considered that the measured value of the signal quality of the first signal within the third time period is greater than or equal to the second threshold value. The embodiment of the present application does not limit this.

[0176] In the embodiment of the present application, the fourth indication information may include a measured value of the signal quality of the first signal within the third time period, or the fourth indication information may include a first identifier, and the first identifier is used to characterize that the signal quality of the first signal is greater than or equal to the second threshold. In the case where the fourth indication information includes the measured value of the signal quality of the first signal within the third time period, the first network device may determine that the measured value of the signal quality of the first signal is greater than or equal to the second threshold based on the measured value of the signal quality of the first signal within the third time period.

[0177] In another possible implementation method in the embodiment of the present application, the third indication information is determined based on business requirements, QoS flow requirements, or requirements of specific scenarios, etc., and the embodiment of the present application does not limit this.

[0178] Optionally, in an embodiment of the present application, for the second threshold in the third preset condition and the fourth first preset condition, the description is similar to the first threshold in one of the first preset conditions. Due to the different receivers for measuring the first signal in the embodiment of the present application, the above-mentioned first threshold and the second threshold may be the same or different, that is, when the receivers for measuring the first signal are the same, the first threshold is equal to the second threshold, and when the receivers for measuring the first signal are different, the first threshold and the second threshold are different. The embodiment of the present application does not make any specific limitation on this.

[0179] Optionally, in an embodiment of the present application, for preset conditions three and four, the communication method provided in the embodiment of the present application is mainly applied to a terminal device in a connected state, but the embodiment of the present application is not limited to this.

[0180] Optionally, in an embodiment of the present application, the terminal device measures the received first signal to obtain a measurement value of the signal quality of the first signal. In another possible implementation method, the terminal device can directly send the measurement value of the signal quality of the first signal to the first network device. Further, the first network device can determine or adjust the coverage range of the first signal of one of the above-mentioned first preset conditions based on the measurement value, or adjust the parameters in the first configuration information used to configure the first signal, such as enhanced coverage, time domain or frequency domain repeated coverage, expanded bandwidth, low complexity channel coding, power boosting, frequency hopping, etc. The embodiment of the present application is not limited to this.

[0181] In the embodiment of the present application, if the terminal device is a terminal device that is not at the edge of the cell or a stationary terminal device, since the working mode of the terminal device that is not at the edge of the cell or the stationary terminal device is basically unchanged, the first duration, the second duration, the third duration, etc. in the first preset condition can be set to be larger to avoid the waste of system overhead caused by switching the working mode. Exemplarily, the stationary terminal device can be a terminal device with a moving speed lower than a certain threshold, such as a terminal device with a speed of zero or a speed lower than a certain threshold. Exemplarily, the stationary terminal device can be a terminal device that is stationary relative to the center of the cell or a terminal device that moves slower relative to the center of the cell, and the embodiment of the present application does not limit this.

[0182] In one possible implementation, the terminal device determines itself as a terminal device that is not at the edge of a cell or the terminal device that is not at the edge of a cell may be determined based on an instruction from the first network device or the terminal device may be determined based on its own circumstances, and this application does not limit this.

[0183] In an embodiment of the present application, the measurement value of the signal quality of the first signal may be a reference signal received power (RSRP), a reference signal received quality (RSRQ), a received signal strength indicator (RSSI), a low-power reference signal received power (LP-RSRP), a low-power reference signal received quality (LP-RSRQ), a low-power received signal strength indicator (LP-RSSI), a signal plus interference to noise ratio (SINR), a low-power signal plus interference to noise ratio (LP-SINR), a signal to noise ratio (SNR), or energy detection; or the measurement value of the signal quality of the first signal may be related to a signal detection rate, and the signal detection rate may be x / y, where x represents the number of first signals received within a period of time, and y represents the number of first signals successfully decoded within a period of time. Each parameter may be measured by the first receiver or by the second receiver, and this is not limited in the embodiments of the present application.

[0184] Exemplarily, RSRP is the power value of the cell common reference signal within the measurement bandwidth received by the terminal device. The value is the linear average of the power of a single resource element (RE) within the measurement bandwidth, which can reflect the strength of the useful signal in this cell; RSSI is the linear average of the power of all signals received by the terminal device (including useful signals and interference of the same frequency, adjacent frequency interference, thermal noise, etc.), which reflects the load intensity on the resource; RSRQ is the ratio of z times RSRP to RSSI, that is, RSRQ = z*RSRP / RSSI, where z represents the number of REs contained in the measurement bandwidth of RSSI, which can reflect the relative size between the signal and the interference; SINR is the ratio of the useful signal power to the sum of the interference and noise power, which directly reflects the quality of the received signal.

[0185] Exemplarily, LP-RSSI or energy detection can be defined as: the linear average of the total received power on the RSSI resource. LP-RSRP can be defined as: the linear average of the received power on the resource of the reference signal or signal part. LP-SINR is equal to the ratio of LP-RSRP to the sum of interference and noise power, that is, LP-SINR = LP-RSRP / (sum of interference and noise power). LP-RSRQ = N*LP-RSRP / LP-RSSI, where N is the resource size difference factor for evaluating LP-RSRP and LP-RSSI, which can reflect the relative size between LP-RSRP and LP-RSSI.

[0186] In the embodiment of the present application, the second indication information and the third indication information may be a unicast message or a broadcast message. Exemplarily, when the second indication information and the third indication information are broadcast messages, the second indication information and the third indication information may be system information (SI), master information block (MIB), system information block (SIB), etc., or may be an RRC message, such as an RRC connection release message, an RRC reconfiguration message, etc., or may be LP-WUS, LP-SS, LP-RS, SSB, synchronization signal and physical broadcast channel block (SS / PBCH block), downlink control information (DCI), listening signal, beacon frame (beacon), channel state information reference signal (CSI-RS), primary synchronization signal (PSS), secondary synchronization signal (SSS), downlink data, etc., which is not limited in the embodiment of the present application.

[0187] For the above step S320:

[0188] In an embodiment of the present application, in a possible implementation method, the terminal device periodically determines and sends the first indication information, or the terminal device periodically determines and sends the first indication information with the frame number of the received broadcast message as the period. For example, the terminal device determines the working mode once every 30 minutes, and sends the first indication information. Among them, 10 minutes before the terminal device determines the working mode, the terminal device may switch the working mode, or the terminal device may not switch the working mode. For example, the terminal device determines and sends the first indication information at 10:00, at 10:19, the working mode of the terminal device is the first mode, and at 10:20, the terminal device switches the working mode, that is, at 10:20, the working mode of the terminal device is the second mode, but at this time the terminal device will not determine the first indication information, that is, determine the working mode, and the terminal device will only determine and send the first indication information at 10:30.

[0189] In another possible implementation, the terminal device determines and sends the first indication information when switching the working mode. For example, at 10:19, the working mode of the terminal device is the first mode, and at 10:20, the terminal device switches the working mode, that is, at 10:20, the working mode of the terminal device is the second mode, and further, the terminal device determines and sends the first indication information at 10:20.

[0190] The above possible implementations provide two examples of the terminal device determining and sending the first indication information. Of course, there may be other situations where the terminal device determines and sends the first indication information, which is not limited in the embodiments of the present application. For the above step S330:

[0191] Optionally, in an embodiment of the present application, the first network device communicates with the terminal device according to the first indication information, including: when the first indication information indicates that the working mode of the terminal device is the first mode, the first network device communicates with the terminal device through the first receiver; or, when the first indication information indicates that the working mode of the terminal device is the second mode, the first network device communicates with the terminal device through the second receiver.

[0192] Optionally, in an embodiment of the present application, after the first network device receives the first indication information from the terminal device, it can send first feedback information to the terminal device, and the first feedback information is used to instruct the first network device to communicate with the terminal device according to the first indication information.

[0193] It should be noted that, in a possible implementation, after the terminal device sends the first indication information to the first network device, it may not immediately be in the working mode indicated by the first indication information. Exemplarily, when the terminal device sends the first indication information to the first network device, it is in a connected state, the working mode of the terminal device is the second mode, and the working mode indicated by the first indication information is the first mode. When the terminal device releases the network connection, the working mode of the terminal device switches to the first mode, that is, when the terminal device sends the first indication information to the first network device, it is not in the first mode indicated by the first indication information, and the terminal device is in the first mode indicated by the first indication information when releasing the connection state; Exemplarily, when the terminal device sends the first indication information to the first network device, it is in an idle state, the working mode of the terminal device is the second mode, and the working mode indicated by the first indication information is the first mode. When the terminal device receives the first feedback information from the first network device, the working mode of the terminal device switches to the first mode. This application does not limit this. According to the communication method provided in the embodiment of the present application, after the terminal device determines the working mode of the terminal device according to the first preset condition, the terminal device sends first indication information for indicating the working mode of the terminal device. The first network device can communicate with the terminal device through the corresponding receiver according to the first indication information, so that the working mode of the terminal device itself is aligned with the working mode of the terminal device determined by the first network device according to the first indication information. Then, the first network device and the terminal device can communicate using the corresponding receiver, avoiding the misalignment between the working mode of the terminal device itself and the working mode determined by the first network device, but still using misaligned receivers for communication and causing waste of resources.

[0194] Based on the above Figure 3 In the embodiment shown, in a possible implementation method, the communication method provided in the embodiment of the present application also includes: the first network device sends first configuration information to the terminal device, the first configuration information is used to configure the first signal, and the first configuration information includes at least one of the following: a first duration, a second duration, a first threshold, a third duration, and a second threshold.

[0195] After the terminal device obtains the first configuration information, it can further determine the relationship between the measured value of the signal quality of the first signal and the first threshold or the second threshold, thereby implementing the solution described in the above embodiment.

[0196] In an embodiment of the present application, the first configuration message may be sent via a broadcast message. Exemplarily, the first configuration message may be SI, MIB, SIB, etc.; the first message may also be an RRC message, such as an RRC connection release message, an RRC reconfiguration message, etc.; the first configuration information may also be LP-WUS, LP-SS, LP-RS, SSB, SS / PBCH block, DCI, listening signal, beacon, CSI-RS, PSS, SSS, downlink data, etc., which is not limited to the embodiment of the present application.

[0197] In a possible implementation, the communication method provided by the embodiment of the present application also includes: the second network device sends a first cell list to the terminal device. Accordingly, the terminal device receives the first cell list from the second network device in, for example, a connected state, and the network device corresponding to the cell indicated by the first cell list is a network device with which the terminal device communicates using the first receiver, that is, the first cell list indicates a list of cells, and the terminal device uses the first receiver to communicate with the network device corresponding to the cell in the first cell list. Among them, the second network device may be a network device whose network connection of the terminal device is to be released. It should be understood that the terminal device can receive the first cell list of the second network device through, for example, a broadcast message in an idle state or a non-connected state, and this application does not limit this.

[0198] Optionally, in the embodiment of the present application, the first cell list may be carried in a release connection message corresponding to the second network device. When the terminal device resides in a cell indicated by the first cell list, the terminal device may communicate with the corresponding network device using the first receiver.

[0199] In the embodiment of the present application, the network device corresponding to the cell can be understood as the network device serving the cell. For example, the terminal device resides in the first cell, and the network device serving the first cell is the third network device. If the first cell is the indicated cell in the first cell list, when the terminal device resides in the first cell, the terminal device uses the first receiver to communicate with the third network device.

[0200] Optionally, the second network device and the first network device in the embodiment of the present application may be the same network device, or may be different network devices, and the embodiment of the present application does not specifically limit this.

[0201] In an embodiment of the present application, the terminal device can obtain multiple network devices corresponding to the cells in the first cell list at one time by receiving the first cell list from the second network device. When the terminal device resides in a certain cell, it only needs to know whether the cell is in the first cell list to determine whether to use the first receiver to communicate with the network device corresponding to the cell. There is no need to determine the working mode according to the first preset condition, and the implementation complexity is lower. When the first preset condition corresponds to receiving indication information, resources used for indication are saved.

[0202] In a possible implementation, the communication method provided in the embodiment of the present application further includes: the first network device sends sixth indication information to the terminal device. Accordingly, the terminal device receives the sixth indication information from the first network device, and the sixth indication information is used to instruct the terminal device to communicate with the first network device through the first receiver.

[0203] Optionally, in an embodiment of the present application, the first network device may be a network device for releasing the network connection of the terminal device, and the sixth indication information may be carried in a connection release message sent by the first network device to the terminal device.

[0204] In an embodiment of the present application, the terminal device can determine the working mode of the terminal device by using the sixth indication information that instructs the terminal device to communicate with the first network device through the first receiver, thereby reducing the implementation complexity and avoiding the additional resource overhead caused by the terminal device itself determining the working mode.

[0205] Furthermore, the terminal device is currently in a different RRC state, and the first indication information needs to be sent in a corresponding manner.

[0206] In one possible implementation, the terminal device is currently in the RRC_CONNECTED state, and the terminal device can directly send the first indication information to the first network device.

[0207] Optionally, in an embodiment of the present application, the terminal device is in the RRC_CONNECTED state, and the first indication information sent by the terminal device to the first network device may be included in a field of an existing message, such as a Cause value field included in a radio resource control protocol (radio resource control, RRC) establishment request message, and the size of the Cause value field may be 1 bit; or, the first indication information sent by the terminal device to the first network device may reuse an existing field, such as multiplexing certain bits in a multiple access channel (multiple access channel, MAC) control element (control element, CE) field; or, the first indication information sent by the terminal device to the first network device may be a broadcast message, such as a message information block (system information block, SIB), service information (service informationatio, SI), etc.; or, the first indication information sent by the terminal device to the first network device may be a new message or signaling; or, the first indication information sent by the terminal device to the first network device may be included in a new message or signaling, and the embodiment of the present application does not limit this.

[0208] For scenarios without uplink scheduling,

[0209] Exemplarily, in the case where the terminal device periodically determines and sends the first indication information, the first indication information may be sent on a new resource for sending the first indication information that is periodically configured on a physical uplink control channel (PUCCH).

[0210] Exemplarily, in the case where the terminal device determines and sends the first indication information after switching the working mode, the first indication information may be sent via a scheduling request (SR) resource on the PUCCH.

[0211] Exemplarily, the first indication information may be sent in a contention-based random access procedure (Message 3, Msg3).

[0212] For scenarios with uplink scheduling,

[0213] Exemplarily, the first indication information may be included in MAC CE signaling or RRC signaling.

[0214] In another possible implementation, the terminal device is currently in the RRC_IDLE state.

[0215] Exemplarily, the first indication information may be included in (Message 5, Msg5) and sent.

[0216] Exemplarily, the first indication information may be sent in an RRC connection establishment completion message.

[0217] Exemplarily, the first indication information may be included in an uplink confirmation message. For example, the uplink confirmation message may be a hybrid automatic repeat request confirmation (HARQ-ACK) or an automatic repeat request confirmation message (ARQ-ACK). This embodiment of the present application does not limit this.

[0218] In an embodiment of the present application, for the paging scenario, when the terminal device is in the RRC_IDLE state, the terminal device is paged through the core network paging method. Therefore, the terminal device needs to send a first indication information to the core network device to align the working mode, and the first network device is the core network device. For example, the working mode indicated by the first indication information is the first mode, and the core network device can use the first signal to page the terminal device. Among them, the first indication information can be carried in the message described in the above example. In another possible implementation method, the terminal device is currently in the RRC_INACTIVE state, or an inactive state.

[0219] Exemplarily, the first indication information may be carried in a transmission scheduling message such as msg3, or the first indication information may be carried in an RRC connection establishment request (RRC connection request) message, an RRC re-establishment request (RRCReestablishmentRequest), an RRC recovery connection request (RRCResumeReuqest), or an RRC establishment connection request (RRCSetupRequest) and sent, and the embodiments of the present application do not limit this.

[0220] In the embodiment of the present application, for the paging scenario, when the terminal device is in the RRC_INACTIVE state, the terminal device is paged by RAN paging. Therefore, the terminal device needs to send a first indication information to the access network device to align the working mode, and the first network device is the access network device. For example, the working mode indicated by the first indication information is the first mode, and the access network device can use the first signal to page the terminal device. The first indication information is carried in the message described in the above example. Figure 4It is a schematic diagram of another example of the communication method provided in an embodiment of the present application. The method is illustrated by taking the interaction between a terminal device and a first network device as an example. Of course, the subject that executes the terminal device action in the method may also be a device / module in the terminal device, such as a chip, a processor, a processing unit, etc. in the terminal device; the subject that executes the network device action in the method may also be a device / module in the network device, such as a chip, a processor, a processing unit, etc. in the network device, and the embodiment of the present application does not specifically limit this. The processing performed by a single execution subject (for example, a terminal device or a first network device) in an embodiment of the present application may also be divided into executions by multiple execution subjects, and these execution subjects may be logically and / or physically separated. For example, the processing performed by the first network device may be divided into executions by at least one of CU, DU and RU. Exemplary, such as Figure 4 As shown, the method 400 includes:

[0221] S410, the terminal device determines a measurement value of the signal quality of the first signal.

[0222] In the embodiment of the present application, the description on how to measure the first signal through the corresponding receiver to obtain the measurement value of the signal quality of the first signal can refer to the relevant description in step S310, which will not be repeated here.

[0223] S420, the terminal device sends fourth indication information or fifth indication information to the first network device. Correspondingly, the first network device receives the fourth indication information or fifth indication information.

[0224] In the embodiment of the present application, the description of the fourth indication information and the fifth indication information can refer to the description in step S310, which will not be repeated here.

[0225] S430, the first network device sends second indication information or third indication information to the terminal device.

[0226] In the embodiment of the present application, the description of the second indication information and the third indication information can refer to the description in step S310, which will not be repeated here.

[0227] S440, the terminal device communicates with the first network device according to the second indication information or the third indication information.

[0228] In an embodiment of the present application, the terminal device determines the working mode as the second mode according to the second indication information, and the terminal device communicates with the first network device through the second receiver; or, the terminal device determines the working mode as the first mode according to the third indication information, and the terminal device communicates with the first network device through the first receiver.

[0229] In the communication method provided in the embodiment of the present application, the terminal device measures the first signal and obtains the measured value of the signal quality of the first signal. By sending the fourth indication information indicating that the measured value of the signal quality of the first signal is greater than or equal to the second threshold to the first network device, the first network device sends the second indication information indicating that the terminal device determines the working mode as the second mode, or, by sending the fifth indication information indicating that the measured value of the signal quality of the first signal is less than the second threshold to the first network device, the first network device sends the third indication information indicating that the terminal device determines the working mode as the first mode. Further, the terminal device communicates with the first network device through the corresponding receiver according to the working mode indicated by the received second indication information or the third indication information. Among them, after the first network device sends the second indication information or the third indication information to the terminal device, it defaults to communicate with the terminal device according to the working mode indicated by the second indication information or the third indication information, and the working modes of the terminal device and the first network device are aligned through the indication of the first network device, avoiding the misalignment of the working mode of the terminal device itself and the working mode determined by the first network device, but still using the misaligned receiver for communication and causing waste of resources. Furthermore, the first network device performs a complex process of determining the working mode, making the processing of the terminal device simpler.

[0230] The above mainly introduces the scheme provided by the embodiment of the present application from the perspective of the interaction between the terminal device and the first network device.
