[0199] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0200] Step S2101: The first terminal sends first indication information to the second terminal.

[0201] The first terminal may serve as a relay device (or relay terminal) between the second terminal and the network device.

[0202] Optionally, the first terminal may be a relay device (or relay terminal) in a User Equipment to Network (U2N) relay.

[0203] The first indication information is used to indicate the first quantity.

[0204] In some embodiments, the first number may be the number of links required for the first terminal to access the network device. For example, the first number may be the number of wireless links required for the first terminal to access the network device.

[0205] In some embodiments, the first number may also be the number of relay terminals required for the first terminal to access the network device. For example, the first number may be the number of relay terminals that the first terminal passes through when connecting to the network device, or in other words, the first number may be the number of relay terminals between the first terminal and the network device.

[0206] In some embodiments, the first number may also be the hop count of the first terminal.

[0207] Optionally, the hop count of the first terminal may be the number of links required for the first terminal to access the network device, or the hop count of the first terminal may be the number of relay terminals required for the first terminal to access the network device.

[0208] In some embodiments, the first terminal may send a discovery signal to the second terminal, where the discovery signal includes the first indication information, so as to send the first indication information to the second terminal.

[0209] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0210] Step S2102: The second terminal determines the channel measurement result of the first terminal.

[0211] Among them, the channel measurement result can be the result obtained by measuring and evaluating the channel between the first terminal and the second terminal. The channel measurement result may include various types of performance data such as bandwidth, signal strength, signal quality (such as signal noise level, interference level, bit error rate, etc.), delay, jitter, signal-to-noise ratio, etc. Optionally, the channel measurement result may also include other types of performance data, which is not limited in the embodiments of the present disclosure.

[0212] In some embodiments, the second terminal may measure the signal quality of the first terminal to determine a channel measurement result of the first terminal.

[0213] In some embodiments, the first terminal can measure the signal quality by itself to obtain its own channel measurement result, and then send second indication information to the second terminal. The second indication information can be used to determine the channel measurement result of the first terminal; the second terminal can receive the second indication information sent by the first terminal to determine the channel measurement result of the first terminal based on the second indication information.

[0214] It should be noted that the first terminal mentioned in step S2101 and step S2102 can be a set consisting of multiple first terminals, each first terminal can send first indication information to the second terminal, and the first quantity indicated by the first indication information sent by different first terminals can be different; and the second terminal can obtain the channel measurement results of each first terminal.

[0215] Step S2103: The second terminal sends at least part of the channel measurement result of the first terminal to the network device based on the first quantity.

[0216] In some embodiments, the second terminal may receive the first indication information sent by each first terminal to obtain the first number of each first terminal.

[0217] For example, the second terminal may receive the discovery signal sent by the first terminal to obtain the first indication information included in the discovery signal, thereby obtaining the first quantity.

[0218] In some embodiments, after obtaining the first number of each first terminal, the second terminal can determine the first number of third terminals from the first terminals that meet the first threshold based on the first number of each first terminal, and thus send the channel measurement results of the third terminals to the network device.

[0219] The second terminal performs screening in the first terminal according to the first quantity so that the second terminal can send the channel measurement results of the first number of third terminals that meet the first threshold to the network device, thereby ensuring that the channel measurement results received by the network device correspond to the first number of first terminals that meet the first threshold.

[0220] In some embodiments, the second terminal may send the channel measurement result of each first terminal and the first number of first terminals to the network device.

[0221] By sending the first number and channel measurement results of each first terminal to the network device, the network device can screen the first terminals based on the received first number to obtain the channel measurement results of the first terminals (i.e., the third terminals) whose first number meets the first threshold.

[0222] In some embodiments, the first threshold can be determined based on the first signaling sent by the network device, that is, the network device can send the first signaling to the second terminal, and after receiving the first signaling, the second terminal can determine the first threshold based on the received first signaling.

[0223] The first signaling may be dedicated signaling. For example, the network device may send dedicated signaling to the second terminal to configure the first threshold through the dedicated signaling.

[0224] In some embodiments, the second terminal may also determine the first threshold based on service configuration information.

[0225] Optionally, the second terminal may determine the first threshold according to service configuration information of the application layer.

[0226] Optionally, the second terminal may determine the first threshold based on service configuration information of the V2X layer.

[0227] The service configuration information may be used to indicate the QoS requirements of the service, and / or the service configuration information may be used to indicate the latency requirements of the service, etc. The embodiments of the present disclosure do not limit the specific types of the service configuration information.

[0228] For example, the correspondence between different types of services and the first threshold value may be configured to implement configuration of the service configuration information, so that the first threshold value may be determined based on the correspondence indicated by the service configuration information.

[0229] For another example, the correspondence between the service QoS and the first threshold may be configured to implement configuration of the service configuration information, so that the first threshold may be determined based on the correspondence indicated by the service configuration information.

[0230] Optionally, the first quantity satisfying the first threshold may be that the first quantity is less than or equal to the quantity threshold.

[0231] In some embodiments, the sending process described in step S2103 may be periodically triggered. For example, the second terminal may send the channel measurement result to the network device once every first time period, that is, based on the first quantity.

[0232] In some embodiments, terms such as "duration", "period", "time window", "window", and "time" can be replaced with each other, and terms such as "moment", "time point", "time", and "time position" can be replaced with each other.

[0233] Alternatively, the sending process described in step S2103 may be event-triggered. For example, the second terminal may trigger a process of sending at least part of the first terminal's channel measurement results to the network device based on the first quantity when any of the following events occurs:

[0234] Event X1: The channel measurement result of the first terminal currently serving the second terminal is lower than the first threshold, and the channel measurement result of the cell is higher than the second threshold;

[0235] Event X2: a channel measurement result of the first terminal currently providing service to the second terminal is lower than a third threshold;

[0236] Event Y1: The channel measurement result of the primary cell (PCell) is lower than the first threshold, while the channel measurement result of the candidate first terminal is higher than the second threshold;

[0237] Event Y1: the channel measurement result of the candidate first terminal is higher than the fourth threshold;

[0238] Among them, event X1 and event X2 are used for the process in which the second terminal currently accesses the network through a relay device and needs to switch from the relay device to the cell; event Y1 and event Y2 are used for the process in which the second terminal currently directly accesses the cell and needs to switch from the cell to the relay device.

[0239] Optionally, the first threshold, the second threshold, the third threshold, and the fourth threshold may take any values, which are not limited in the embodiment of the present disclosure.

[0240] In some embodiments, the second device may maintain a device list to store the device information of the first terminal sent through the device list.

[0241] In some embodiments, at least part of the device information of the first terminal may be stored in a device list maintained by the second terminal.

[0242] Optionally, first device information of third terminals may be stored in the device list, where the third terminals are third terminals whose first number meets a first threshold among the first terminals, and the first device information includes a device identifier and a channel measurement result.

[0243] Optionally, the second device information of each first terminal may be stored in the device list, where the second device information includes a device identifier, a channel measurement result, and a first quantity.

[0244] Step S2104: The network device performs link selection for the second terminal according to the channel measurement results of at least part of the first terminal sent by the second terminal based on the first quantity.

[0245] In some embodiments, the network device may receive a channel measurement result of the first terminal sent by the second terminal based on the first quantity.

[0246] In some embodiments, the network device may receive a channel measurement result of a third terminal sent by the second terminal, where the third terminal is a portion of the first terminals whose first number meets the first threshold.

[0247] In some embodiments, the network device may perform link selection for the second terminal based on the channel measurement result of the third terminal.

[0248] It should be noted that performing link selection for the second terminal is to determine the communication link between the second terminal and the network device to obtain the first communication link selected for the network device.

[0249] The communication link between the second terminal and the network device may include multiple relay devices (ie, the first terminals), that is, the second terminal may establish a connection to the network device through the relay of multiple first terminals.

[0250] In some embodiments, the network device may receive the channel measurement result of each first terminal and the first number of each first terminal sent by the second terminal.

[0251] In some embodiments, the network device can determine, based on the first number of each first terminal, a portion of the first terminals (i.e., third terminals) whose first number meets the first threshold from the first terminals, and thereby perform link selection for the second terminal based on the channel measurement results of the third terminal to obtain a first communication link selected for the network device.

[0252] In some embodiments, the network device can determine a fourth terminal among the third terminals whose channel measurement results meet the requirements based on the channel measurement results of the third terminal, so as to use the fourth terminal as a terminal adjacent to the second terminal on the first communication link, and the fourth terminal can independently determine the terminal it needs to pass through when connecting to the network device, thereby realizing the determination of the first communication link.

[0253] The channel measurement result meeting the requirements may mean that the performance data meets the corresponding threshold. For example, if the channel measurement result includes bandwidth, the channel measurement result meeting the requirements may mean that the bandwidth is greater than or equal to the bandwidth threshold; if the channel measurement result includes signal strength, the channel measurement result meeting the requirements may mean that the signal strength is greater than or equal to the strength threshold; if the channel measurement result includes bit error rate, the channel measurement result meeting the requirements may mean that the bit error rate is less than or equal to the bit error rate threshold; if the channel measurement result includes delay, the channel measurement result meeting the requirements may mean that the delay is less than or equal to the delay threshold; if the channel measurement result includes signal-to-noise ratio, the channel measurement result meeting the requirements may mean that the signal-to-noise ratio is greater than or equal to the signal-to-noise ratio threshold, and so on.

[0254] Step S2105: The network device sends third indication information to the second terminal.

[0255] The third indication information is used to indicate the first communication link selected by the network device for the second terminal.

[0256] In some embodiments, the third indication information may be used to indicate a fourth terminal selected by the network device for the second terminal, where the fourth terminal is selected from the third terminals and is adjacent to the second terminal on the first communication link.

[0257] Step S2106: The second terminal obtains the second number of fourth terminals based on the third indication information.

[0258] In some embodiments, the second terminal may receive the third indication information to determine, based on the third indication information, the fourth terminal selected by the network device for the second terminal.

[0259] In some embodiments, the third indication information may include a device identification of the fourth terminal, so that the terminal can determine the fourth terminal selected for it by the network device based on the third indication information.

[0260] In some embodiments, the second terminal may obtain a second number of fourth terminals, where the second number is the number of links required for the fourth terminal to currently access the network device or the number of relay terminals required for the fourth terminal to currently access the network device.

[0261] In some embodiments, the fourth terminal may send its second number to the second terminal, so that the second terminal may obtain the second number of the fourth terminal.

[0262] By acquiring the second number of the fourth terminals, changes in the number of links required for the fourth terminals to access the network device or the number of relay terminals required for the fourth terminals to access the network device can be monitored in a timely manner.

[0263] Step S2107: The second terminal selects a link based on the second number of fourth terminals.

[0264] In some embodiments, the second terminal can determine the change in the number of links required for the fourth terminal to access the network device or the change in the number of relay terminals required for the fourth terminal to access the network device based on the second number of fourth terminals and the first number of fourth terminals indicated by the first indication information, so as to perform link selection based on the change in the number of links required for the fourth terminal to access the network device or the change in the number of relay terminals required for the fourth terminal to access the network device.

[0265] In some embodiments, the second number of the fourth terminal is consistent with the first number of the fourth terminal, and the first number meets the first threshold, thereby ensuring that the second number also meets the first threshold. Therefore, the second terminal can send an access request message to the fourth terminal, and the access request message is used to request to establish a connection with the fourth terminal.

[0266] In some embodiments, the fourth terminal may receive an access request message from the second terminal to establish a connection with the second terminal according to the access request message.

[0267] Furthermore, the fourth terminal may independently determine the connection between itself and the network device to implement the connection between the second terminal and the network device.

[0268] Through the above embodiment, the link switching of the second terminal can be implemented, so that the second terminal can be connected to the network device through the switched link.

[0269] In some embodiments, the second number of the fourth terminals is inconsistent with the first number of the fourth terminals, and the link may not be switched to the first communication link.

[0270] Optionally, if the second number is inconsistent with the first number, it can be determined that the number of links required for the fourth terminal to access the network device or the number of relay terminals required for the fourth terminal to access the network device has changed, and the second number obtained after the change may meet the first threshold or may not meet the first threshold. Regardless of whether the second number of the fourth terminal meets the first threshold, it can be determined that the link selection has failed, so that the link may not be switched to the first communication link.

[0271] In some embodiments, if the second number of the fourth terminals does not meet the first threshold, the link may not be switched to the first communication link.

[0272] Optionally, if the second number of the fourth terminals does not meet the first threshold, it may be determined that the link selection fails, and thus the link may not be switched to the first communication link.

[0273] In some embodiments, the second number of the fourth terminals is inconsistent with the first number of the fourth terminals, and the second number meets the first threshold, and the second terminal can send fourth indication information to the network device, where the fourth indication information is used to indicate the second number.

[0274] In some embodiments, the second number of the fourth terminal does not meet the first threshold, and the second terminal may send fifth indication information to the network device, where the fifth indication information is used to indicate that the second number does not meet the first threshold.

[0275] In some embodiments, in addition to obtaining the second number of the fourth terminal, the second terminal may also obtain the second number of other first terminals. That is, the second terminal may obtain the second number of each first terminal.

[0276] In some embodiments, the second terminal may re-determine a second number of fifth terminals that meet the first threshold from the first terminal, and send the channel measurement results of the fifth terminals to the network device.

[0277] In some embodiments, the second terminal can determine, based on the second number of the first terminals, the first terminals whose second number no longer meets the first threshold. For the first terminals whose second number no longer meets the first threshold, the device information of the first terminal can be deleted from the device list to obtain an updated device list.

[0278] Optionally, if the device list stores first device information of a first number of third terminals that meet a first threshold, the first device information of a second number of third terminals that no longer meet the first threshold may be deleted from the device list.

[0279] Optionally, the device list stores the second device information of each first terminal, and the second device information of the first terminals whose second number no longer meets the first threshold may be deleted from the device list.

[0280] In some embodiments, the second terminal may also report an updated device list to the network device.

[0281] In some embodiments, the network device may receive an updated device list reported by the second terminal.

[0282] In some embodiments, the second terminal may further report the device identification of the deleted first terminal to the network device.

[0283] In some embodiments, the network device may receive a device identification reported by the second terminal, where the device identification is the device identification of the deleted first terminal.
