Description

Communication method and related apparatus

[0001] The present application claims priority from the Chinese Patent Application No. 202411391815.7 filed on September 30, 2024, and entitled "A communication method and related apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication, and in particular to a communication method and related apparatus. BACKGROUND

[0003] At present, the power consumption of a terminal device has a great influence on the endurance and service life of the terminal device. In order to reduce the power consumption, the terminal device can activate a low power wake up signal (LP-WUS) function. In the case of not needing to receive a paging message or not having data transmission, the terminal device turns on a low power wake up receiver (LP-WUR), and a main receiver is in a closed or sleep state. Compared with the main receiver, the power consumption of the LP-WUR is lower. After turning on the LP-WUR, the terminal device can monitor the LP-WUS through the LP-WUR. When the LP-WUS is received, the terminal device needs to turn on the main receiver to monitor a paging message, control information, or transmission data.

[0004] However, when the terminal device is configured with multiple discontinuous reception (DRX) groups, for example, two DRX groups, the terminal device cannot determine the position of monitoring the LP-WUR, which can cause the terminal device to fail to receive the LP-WUS in time, and further cause the time delay of the terminal device receiving data to be too large. SUMMARY

[0005] The present application provides a communication method and related apparatus for determining the position of monitoring the LP-WUR, so as to reduce the time delay of the terminal device receiving data.

[0006] The first aspect of the present application provides a communication method, which is applied to a terminal device side, for example, can be applied to a terminal device or a communication module in the terminal device, or a circuit or chip responsible for communication function in the terminal device (such as a modem chip, also known as a baseband chip, or a system on chip (SoC) chip or a system in package (SIP) chip containing a modem core), for example, in the case of applying the method to a terminal device, in the method, the terminal device determines a first position for monitoring a first signal according to first information, the first information includes first indication information, service information or a working frequency point of the first signal, the first position is related to a first discontinuous reception (DRX) group and / or a second DRX group, and the first signal includes a low-power wake-up signal (LP-WUS); and the terminal device monitors the first signal at at least one position in the first position.

[0007] In the first aspect, the terminal device can determine the monitoring position of the first signal. Taking the first signal as an LP-WUS for example, the first aspect can solve the problem of being unable to determine the monitoring position of the LP-WUS, and since the terminal device determines the monitoring position of the LP-WUS based on the first information, the first information can be the first indication information, the service information or the working frequency point of the LP-WUS. Therefore, the final determination of the monitoring position of the LP-WUS is adapted to the first indication information, the service information or the working frequency point of the LP-WUS. Taking the first information as the service information for example, the monitoring position of the LP-WUS is determined according to the service information, which can make the monitoring of the LP-WUS adapt to the service situation and reduce the latency of receiving a physical downlink control channel (PDCCH). For example, when the service information is a device corresponding to the first DRX group, it indicates that there is service on the first DRX group, and the first position can be related to the first DRX group, for example, the first position can be adapted to the configuration information of the first DRX group, so that the terminal device can timely receive the LP-WUS sent on the first DRX group at the first position, and the LP-WUS can be used to indicate whether the terminal device needs to monitor the PDCCH. The terminal device can timely start monitoring the PDCCH by timely receiving the LP-WUS, thereby reducing the latency of receiving the PDCCH and further reducing the data transmission latency.

[0008] Optionally, the above-mentioned "the terminal device determines a first position for monitoring a first signal according to first information" can also be replaced by one or more of the following:

[0022] Optionally, the terminal device can monitor the first signal through the LP-WUR.

[0023] Optionally, the first position can be a time domain position. For example, the first position is one or more time units, and the terminal device monitors the first signal on the one or more time units.

[0024] Optionally, the first position can be continuous, discontinuous, or partially continuous and partially discontinuous. For example, when the first position is a time domain position, the first position can be a plurality of continuous time units; or, the first position can be a plurality of discontinuous time units; or, the first position is a plurality of time units, which includes a plurality of continuous time units and a plurality of discontinuous time units; or, the first position is one or more time unit sets, and the time units in each time unit set are continuous, and the time unit sets are discontinuous.

[0025] Optionally, the service information includes a quality of service (QoS) flow. The QoS flow is an example of a possible expression, and can be replaced by any possible expression, for example, quality of service information or information indicating quality of service.

[0026] Optionally, when the first signal is sent by a network device, the working frequency point of the first signal can be one or more of the working frequency points of the network device.

[0027] Optionally, the working frequency point of the first signal can be one or more of the frequency points on the band corresponding to the first DRX group, and / or one or more of the frequency points on the band corresponding to the second DRX group.

[0028] Optionally, the first signal can be deployed on the first DRX group, or the first signal can be sent on one or more frequency points on the band corresponding to the first DRX group; and / or, the first signal can be deployed on the second DRX group, or the first signal can be sent on one or more frequency points on the band corresponding to the second DRX group.

[0029] Optionally, the terminal device can be configured with the first DRX group and the second DRX group, and other DRX groups, for example, a third DRX group, can also be configured in the terminal device.

[0030] Optionally, the first DRX group and the second DRX group correspond to different working frequency points, or different bands, or different frequency ranges, respectively. For example, the first DRX group corresponds to a low frequency band, the second DRX group corresponds to a high frequency band, the first DRX group corresponds to a high frequency band, the second DRX group corresponds to a low frequency band, the first DRX group corresponds to a frequency range 1 (FR1), and the second DRX group corresponds to a frequency range 2 (FR2); or, the second DRX group corresponds to FR2, and the first DRX group corresponds to FR1.

[0031] Optionally, the configuration information of the DRX group (for example, the first DRX group and the second DRX group) includes the length of the first timer, and the first timer includes an onDurationTimer and a drx-inactivityTimer or other Timer. The onDurationTimer is an example of a possible expression, and can be replaced by any possible expression, for example, a drx-inactivityTimer.

[0032] Optionally, the network device can configure the length of the onDurationTimer and / or the drx-inactivitytimer for the terminal device through RRC signaling.

[0033] Optionally, the first timer described above can be a first timer of the first DRX group and / or a first timer of the second DRX group.

[0034] Optionally, the length of the first timer of the first DRX group is different from the length of the first timer of the second DRX group. Hereinafter, an example in which the length of the first timer of the first DRX group is greater than the length of the first timer of the second DRX group is described.

[0035] Optionally, the terminal device receives a first signal at a first time. The first signal indicates whether the terminal device needs to monitor the PDCCH within the length of the first timer after the gap. The time at which the gap starts is the first time, and the time at which the gap ends is the second time. Assuming that the first signal indicates that the terminal device monitors the PDCCH, the time at which the gap ends, i.e., the second time, is the time at which the terminal device starts to monitor the PDCCH, the length of the first timer is the duration of monitoring the PDCCH, and the length of the first timer is also the duration of not monitoring the first signal. The duration of the interval between the second time and the third time is the length of the first timer, and the terminal device stops monitoring the PDCCH at the third time. The first position of monitoring the first signal is one or more positions other than the position corresponding to the first timer, i.e., one or more positions other than the time domain position from the second time to the third time. It can be seen that the position of not monitoring the first signal can be determined according to the length of the first timer, and the first position of monitoring the first signal can be determined.

[0036] Optionally, the value of the gap depends on the sleep state of the main receiver of the terminal device during monitoring of the first signal. For example, when the main receiver of the terminal device is in a micro-sleep state, the gap is 0; when the main receiver of the terminal device is in a light-sleep state, the gap is 6 ms; and when the main receiver of the terminal device is in a deep-sleep state, the gap is 20 ms.

[0037] Optionally, the value of the gap also depends on the time required for synchronization of the terminal device. For example, when the terminal device needs to receive 1 synchronization signal block (SSB) for synchronization, the gap also needs to include the time required for receiving 1 SSB after waking up the main receiver of the terminal device; and when the terminal device needs to receive 2 SSBs for synchronization, the gap also needs to include the time required for receiving 2 SSBs after waking up the main receiver of the terminal device.

[0038] Optionally, the terminal device can determine, according to the first information, a length of a first timer of the first DRX group, or a length of a first timer of the second DRX group, or a length of a first timer of the first DRX group and the second DRX group. The length of the first timer of the first DRX group refers to determining the first position for monitoring the first signal according to the length of the first timer of the first DRX group, the length of the first timer of the second DRX group refers to determining the first position for monitoring the first signal according to the length of the first timer of the second DRX group, and the length of the first timer of the first DRX group and the second DRX group refers to determining the first position for monitoring the first signal according to the length of the first timer of the first DRX group and the length of the first timer of the second DRX group. For example, the union of the first timer of the first DRX group and the first timer of the second DRX group is determined according to the first information. For example, the intersection of the first timer of the first DRX group and the first timer of the second DRX group is determined according to the first information.

[0039] Optionally, when the first signal indicates that the terminal device monitors the PDCCH, the first position can be one or more positions other than the time domain position corresponding to the first timer.

[0040] Optionally, the time domain position corresponding to the first timer includes a time domain position from the second time point to the third time point. As described above, the second time point is the time point at which the PDCCH starts to be monitored, and the length of time between the second time point and the third time point is the length of the first timer. Taking FIG. 8 as an example, the second time point is time point B, and the third time point is time point C or time point D. The length of time between time point B and time point C is the length of the first timer of the first DRX group, and the length of time between time point B and time point D is the length of the first timer of the second DRX group.

[0041] Optionally, when the first signal indicates that the terminal device does not monitor the PDCCH, the first position includes the time domain position corresponding to the first timer.

[0042] Optionally, if the terminal device monitors the PDCCH during the first timer, the second timer is started. After the second timer is started, the length of time for monitoring the PDCCH can be extended.

[0043] Optionally, the second timer includes a drx-inactivityTimer.

[0044] Optionally, the second timer described above can be a second timer of the first DRX group and / or a second timer of the second DRX group.

[0045] Optionally, the terminal device can determine, according to the first information, a length of a second timer of the first DRX group, or a length of a second timer of the second DRX group, or a length of a second timer of the first DRX group and the second DRX group. For example, when the length of the second timer of the first DRX group and the second DRX group is adopted, the second timer can be an intersection or a union of the second timer of the first DRX group and the second timer of the second DRX group.

[0046] Optionally, the terminal device determines, according to the first information, a position of monitoring the first channel; or the terminal device determines, according to the first information, a time domain position of monitoring the first channel; or the terminal device determines, according to the first information, a frequency domain position of monitoring the first channel; or the terminal device determines, according to the first information, a time domain resource of monitoring the first channel; or the terminal device determines, according to the first information, a frequency domain resource of monitoring the first channel; or the terminal device determines, according to the first information, a time length of monitoring the first channel; or the terminal device determines, according to the first information, a length of a first timer of monitoring the first channel; or the terminal device monitors the first channel according to the first information, wherein the first channel includes a PDCCH or a physical downlink shared channel (PDSCH).

[0047] Optionally, the terminal device can receive the first information sent by the network device.

[0048] In an optional implementation of the first aspect, the terminal device receives first indication information, the first indication information being used to indicate at least one of the following: the first DRX group, the second DRX group, or the first position. Accordingly, the terminal device receives the first indication information.

[0049] In the above implementation, the first indication information can indicate the first position of monitoring the first signal or indicate the DRX group to be adopted, so that the position of monitoring the first signal by the terminal device can be controlled, so as to match the position of sending the first signal by the network device, or match the service information or service demand obtained by the network device, and the like.

[0050] Optionally, the first indication information includes at least one of the following: an identifier of the first DRX group, an identifier of the second DRX group, a length of a first timer of the first DRX group, a length of a first timer of the second DRX group, a time length corresponding to the first position, a time domain resource corresponding to the first position, or a time domain position corresponding to the first position.

[0051] Optionally, the first indication information can be high-layer signaling, such as radio resource control (RRC) signaling, or media access control (MAC) control element (CE) signaling, or physical-layer signaling, such as downlink control information (DCI), or carried in a data channel, such as a PDSCH.

[0052] Optionally, when the first indication information indicates the first DRX group, the first position is related to the first DRX group, when the first indication information indicates the second DRX group, the first position is related to the second DRX group, and when the first indication information indicates the first DRX group and the second DRX group, the first indication information is related to the first DRX group and the second DRX group.

[0053] Optionally, the network device determines the first indication information according to information of the first service.

[0054] Optionally, the first service can be a service transmitted by the network device or a service to be transmitted by the terminal device.

[0055] Optionally, the information of the first service includes a size of a data packet of the first service. For example, when the size of the data packet of the first service is greater than a threshold A, a DRX group with a longer length of the first timer, i.e., the first DRX group, is selected, the first indication information is used to indicate the first DRX group, and the network device can determine the first position according to configuration information of the first DRX group.

[0056] In an optional implementation of the first aspect, when the terminal device receives the service information transmitted by the first device, the first position is related to configuration information of the first DRX group of the first device, or when the terminal device receives the service information transmitted by the second device, the first position is related to configuration information of the second DRX group of the second device, or when the terminal device receives the service information transmitted by the first device and the second device, the first position is related to configuration information of the first DRX group of the first device and / or the second DRX group of the second device.

[0057] In the above implementation, when the first device has service information transmission, the first position is related to the configuration information of the first DRX group; when the second device has service information transmission, the first position is related to the configuration information of the second DRX group; and when both the first device and the second device have service information transmission, the first position is related to the configuration information of the first DRX group and the configuration information of the second DRX group. That is, the first position can be flexibly adjusted based on the configuration information of the DRX group according to whether the first device and / or the second device has service information transmission, so as to match the position of monitoring the first signal with the service condition, thereby avoiding causing excessive power consumption or excessive time delay.

[0058] In an optional implementation of the first aspect, the first position is related to the configuration information of the DRX group of the operating frequency point.

[0059] In the above implementation, the terminal device can determine the first position of monitoring the first signal according to the configuration information of the DRX group of the operating frequency point of the first signal, so that the finally determined first position of monitoring the first signal is adapted to the configuration information of the DRX group corresponding to the first signal.

[0060] Optionally, when the network device corresponds to the first DRX group and the operating frequency point of the network device includes the operating frequency point of the first signal, the first position is related to the configuration information of the first DRX group of the network device.

[0061] Optionally, when the network device corresponds to the second DRX group and the operating frequency point of the network device includes the operating frequency point of the first signal, the first position is related to the configuration information of the second DRX group of the network device.

[0062] Optionally, when the band corresponding to the first DRX group includes the operating frequency point of the first signal, the first position is related to the configuration information of the first DRX group.

[0063] Optionally, when the band corresponding to the second DRX group includes the operating frequency point of the first signal, the first position is related to the configuration information of the second DRX group.

[0064] In an optional implementation of the first aspect, the first information further includes the first power or the first time delay.

[0065] Based on the above implementation, when the terminal device determines the first position of the first signal, the first power and the first time delay are considered, so that the first position of monitoring the first signal can be adapted to the first power of the terminal device as much as possible, thereby saving the power consumption or the power consumption, or the first position of monitoring the first signal can be adapted to the first time delay of the terminal device as much as possible, thereby reducing the time delay of data transmission.

[0066] Optionally, the first power quantity can be a remaining power quantity of the terminal device.

[0067] Optionally, the first time delay includes a time delay supported by the terminal device, a time delay expected by the terminal device, or a time delay allowed by the terminal device.

[0068] In an optional implementation of the first aspect, when the first power quantity is less than a first threshold, the first position is determined according to configuration information of the second DRX group, and the configuration information of the second DRX group includes a length of a first timer of the second DRX group, and the length of the first timer of the first DRX group is greater than the length of the first timer of the second DRX group.

[0069] Based on the above implementation, when the first power quantity of the terminal device is small, the second DRX with a shorter length of the first timer can be selected. When the length of the first timer is shorter, the time for monitoring the PDCCH is shorter, and thus the time for turning on the main receiver is shorter, thereby reducing power consumption and saving power.

[0070] In an optional implementation of the first aspect, when the first time delay is less than a second threshold, the first position is determined according to configuration information of the first DRX group, and the configuration information of the first DRX group includes a length of a first timer of the first DRX group, and the length of the first timer of the first DRX group is greater than the length of the first timer of the second DRX group.

[0071] Based on the above implementation, when the first time delay of the terminal device is small, the first DRX group with a longer length of the first timer can be selected. When the length of the first timer is longer, the time for monitoring the PDCCH is longer, and thus there is sufficient time to receive the PDCCH, thereby reducing the time delay of data transmission.

[0072] In an optional implementation of the first aspect, the terminal device sends second information, and the second information includes at least one of the following: a second power quantity, a second time delay, configuration information of a supported DRX group, a supported position for monitoring the first signal, configuration information of an expected DRX group, or an expected position for monitoring the first signal. Correspondingly, the network device receives the second information.

[0073] In the above implementation, the network device can adjust the position for the terminal device to monitor the first signal according to the second power quantity, the second time delay, the configuration information of the supported DRX group, and the like, so that the finally determined position for monitoring the first signal matches the information such as the first power quantity or the first time delay, avoids excessive power consumption or excessive time delay, avoids that the determined first position does not match the terminal capability information (such as the configuration information of the supported DRX group) of the terminal device, or avoids that the determined first position does not match the terminal assistance information (such as the configuration information of the expected DRX group) of the terminal device.

[0074] Optionally, the second power is a remaining power of the terminal device.

[0075] Optionally, the second time delay includes a time delay supported by the terminal device, a time delay expected by the terminal device, or a time delay allowed by the terminal device.

[0076] Optionally, the second time delay is the same as or different from the first time delay.

[0077] Optionally, the second information is reported through terminal capability information of the terminal device, and the terminal capability information of the terminal device includes configuration information of a supported DRX group or a position for monitoring the first signal.

[0078] Optionally, the second information is reported through terminal assistance information of the terminal device, and the terminal assistance information of the terminal device includes configuration information of an expected DRX group or a position for monitoring the first signal.

[0079] Optionally, when the second power is less than a third threshold value, the first position is determined according to configuration information of the second DRX group, and the configuration information of the second DRX group includes a length of a first timer of the second DRX group, and a length of a first timer of the first DRX group is greater than the length of the first timer of the second DRX group.

[0080] Optionally, when the second time delay is less than a fourth threshold value, the first position is determined according to configuration information of the first DRX group, and the configuration information of the first DRX group includes a length of a first timer of the first DRX group, and the length of the first timer of the first DRX group is greater than the length of the first timer of the second DRX group.

[0081] Optionally, the second information can further include a size of a cache space or a storage space available to the terminal device. For example, the terminal device can send the second information to the network device, the second information indicating that the size of the cache space or the storage space available to the terminal device is less than a threshold value B, and the terminal device has a smaller space for caching or storing the PDCCH. Accordingly, the network device can determine that a DRX group with a shorter length of the first timer, i.e., the second DRX group, needs to be used, and the network device can send first indication information for indicating the second DRX group, so that the terminal device monitors the first information and / or the first channel according to configuration information of the second DRX group, and the network device sends the first information and / or the first channel according to the configuration information of the second DRX group.

[0082] Optionally, the network device can determine the first indication information according to the second information and information of the first task, i.e., the first indication information can be determined in combination with the second information and the information of the first task.

[0083] The second aspect of the application provides a communication method, which is applied to a network device side, for example, can be applied to a network device or a communication module in the network device, or a circuit or a chip (such as a modem chip, also known as a baseband chip, or a SoC chip or a SIP chip containing a modem core) responsible for a communication function in the network device, for example, the network device, in the method, the network device sends a first signal in at least one of the first positions, the first position is related to the first DRX group and / or the second DRX group, and the first signal includes the LP-WUS.

[0084] In a possible implementation manner of the second aspect, the network device sends first indication information, the first indication information is used to indicate at least one of the following: the first DRX group, the second DRX group or the first position.

[0085] In the above implementation manner, the network device can indicate the first position of the terminal device monitoring the first signal or indicate the DRX group used through the first indication information, so that the network device can control the position of the terminal device monitoring the first signal, so that the position of the terminal device monitoring the first signal matches the position of the network device sending the first signal, or matches the service information or service demand obtained by the network device and the like.

[0086] In a possible implementation manner of the second aspect, the network device sends service information, and the first position is determined according to the configuration information of the first DRX group.

[0087] In the above implementation manner, the network device sends the service information, that is, the network device has service information to be transmitted to the terminal device. Assuming that the network device corresponds to the first DRX group, the first position of monitoring the first signal can be determined according to the configuration information of the first DRX group. It can be seen that in the above implementation manner, the first position of monitoring the first signal can be flexibly adjusted according to the service information of the network device, so that the position of monitoring the first signal matches the service situation, and excessive power consumption or excessive delay is avoided.

[0088] In a possible implementation manner of the second aspect, the first position is related to the configuration information of the DRX group of the working frequency point.

[0089] In the above implementation manner, the first position of monitoring the first signal can be determined according to the configuration information of the DRX group of the working frequency point of the first signal, so that the finally determined first position of monitoring the first signal is adapted to the configuration information of the DRX group corresponding to the first signal.

[0090] In a possible implementation of the second aspect, the network device receives second information, the second information comprising at least one of: the second power consumption, the second time delay, configuration information of a supported DRX group, a supported location for monitoring the first signal, configuration information of an expected DRX group, or an expected location for monitoring the first signal.

[0091] Based on the above implementation, the network device can determine the first location for monitoring the first signal according to the second power consumption or the second time delay sent by the terminal device. For example, when the network device determines the first location for monitoring the first signal according to the second power consumption, the first location for monitoring the first signal is finally adapted to the power consumption of the terminal device, thereby saving the power consumption or the power consumption; for example, when the network device determines the first location for monitoring the first signal according to the second time delay, the first location for monitoring the first signal is finally adapted to the time delay expected or supported by the terminal device, thereby reducing the time delay of data transmission.

[0092] In a possible implementation of the second aspect, when the second power consumption is less than a third threshold, the first location is determined according to configuration information of the second DRX group, the configuration information of the second DRX group comprising a length of a first timer of the second DRX group, the length of the first timer of the first DRX group being greater than the length of the first timer of the second DRX group.

[0093] Based on the above implementation, when the second power consumption of the terminal device is small, the second DRX with a shorter length of the first timer can be selected. When the length of the first timer is shorter, the time for monitoring the PDCCH is shorter, and therefore the time for turning on the main receiver is shorter, thereby reducing the power consumption and saving the power consumption.

[0094] In a possible implementation of the second aspect, when the second time delay is less than a fourth threshold, the first location is determined according to configuration information of the first DRX group, the configuration information of the first DRX group comprising a length of a first timer of the first DRX group, the length of the first timer of the first DRX group being greater than the length of the first timer of the second DRX group.

[0095] Based on the above implementation, when the second time delay of the terminal device is small, the first DRX group with a longer length of the first timer can be selected. When the length of the first timer is longer, the time for monitoring the PDCCH is longer, and there is sufficient time for receiving the PDCCH, thereby reducing the time delay of data transmission.

[0096] In a possible implementation of the second aspect, the first location is determined according to the configuration information of the first DRX group and / or the configuration information of the second DRX group.

[0097] Based on the above implementation manner, the network device can determine the first position for sending the first signal according to the configuration information of the first DRX group, or determine the first position for sending the first signal according to the configuration information of the second DRX group, or the network device can determine the first position for sending the first signal according to the configuration information of the first DRX group and the configuration information of the second DRX group, that is, the network device can flexibly determine the first position for sending the first signal based on the configuration information of any one or more DRX groups, without being limited by the configuration information of the DRX group based on the terminal device.

[0098] The third aspect of the present application provides a communication method, which is applied to the terminal device side, for example, can be applied to the terminal device or the communication module in the terminal device, or the circuit or chip responsible for the communication function in the terminal device (such as the modem chip, also known as the baseband chip, or the SoC chip or SIP chip containing the modem core), for example, the method is applied to the terminal device, in the method, the terminal device sends a first signal in at least one of the first positions, the first positions are related to the first DRX group and / or the second DRX group, and the first signal includes the LP-WUS.

[0099] In the third aspect, the terminal device comprehensively considers the configuration information of the first DRX group and the configuration information of the second DRX group, and determines the second position for monitoring the first signal based on both. Thus, it can be avoided that the first signal cannot be received or cannot be received in time due to missing part of the monitoring positions, and thus the main receiver of the terminal device cannot be woken up in time, resulting in that the PDCCH data cannot be received in time.

[0100] Optionally, the configuration information of the DRX group (for example, the first DRX group and the second DRX group) includes the length of the first timer, and the first timer includes the onDurationTimer, the drx-inactivitytimer or other Timer.

[0101] Optionally, the network device can configure the onDurationTimer and / or the drx-inactivitytimer to the terminal device through RRC signaling.

[0102] Optionally, the length corresponding to the first timer is the length of the first timer, and the following examples are all based on the length of the first timer of the first DRX group being longer than the length of the first timer of the second DRX group.

[0103] Optionally, the second position can be determined according to the first timer.

[0104] Optionally, the second position can be determined according to the first timer of the first DRX group and the first timer of the second DRX group.

[0105] In an optional implementation of the third aspect, the second position is one or more positions outside of an intersection or a union of the third position and the fourth position, the third position being determined according to the configuration information of the first DRX group, and the fourth position being determined according to the configuration information of the second DRX group. For example, the third position and the fourth position are the first timer.

[0106] In the above implementation, when the second position is one or more positions outside of the union of the third position and the fourth position, the time for monitoring the first signal is shorter, and accordingly, the time for monitoring the PDCCH can be longer, so that the PDCCH can be received in time, and the time delay for receiving the PDCCH is reduced. When the second position is one or more positions in the intersection of the third position and the fourth position, the time for monitoring the first signal is longer, and accordingly, the time for monitoring the PDCCH can be shorter, that is, the time for turning on the main receiver is shorter, so that the power consumption can be reduced.

[0107] Optionally, when the second power of the terminal device is less than the first threshold, the second position is one or more positions outside of the intersection of the third position and the fourth position, and when the second time delay of the terminal device is less than the second threshold, the second position is one or more positions outside of the union of the third position and the fourth position.

[0108] In an optional implementation of the third aspect, the terminal device sends third information, the third information including at least one of the following: the second power, the second time delay, support for determining the monitoring position of the first signal according to the configuration information of the first DRX group, support for determining the monitoring position of the first signal according to the configuration information of the second DRX group, support for determining the monitoring position of the first signal according to the configuration information of the first DRX group and the second DRX group, support for the second position being one or more positions outside of the intersection of the third position and the fourth position, support for the second position being one or more positions outside of the union of the third position and the fourth position, expectation of determining the monitoring position of the first signal according to the configuration information of the first DRX group, expectation of determining the monitoring position of the first signal according to the configuration information of the second DRX group, expectation of determining the monitoring position of the first signal according to the configuration information of the first DRX group and the second DRX group, expectation of the second position being one or more positions outside of the intersection of the third position and the fourth position, or expectation of the second position being one or more positions outside of the union of the third position and the fourth position. Accordingly, the network device receives the third information.

[0109] Based on the above implementation manner, the terminal device sends the third information to the network device, so that the network device can determine the first position according to the second power, the second time delay, the terminal capability information (such as supporting determination of the monitoring position of the first signal according to the configuration information of the first DRX group) or the terminal assistance information (such as expecting determination of the monitoring position of the first signal according to the configuration information of the first DRX group) of the terminal device, so as to match the position of monitoring the first signal with the above information, and finally determine the position of the first signal to match the power consumption demand, the time delay demand, the supported capability of the terminal device or the preference of the terminal device.

[0110] The fourth aspect of the present application provides a communication method, which is applied to the network device side, for example, can be applied to the network device or the communication module in the network device, or the circuit or chip (such as a modem chip, also known as a baseband chip, or a SoC chip or SIP chip containing a modem core) responsible for the communication function in the network device. For example, the method is applied to the network device, in which the network device sends a first signal in at least one position of a second position, the second position is determined by the configuration information of a first DRX group and / or the configuration information of a second DRX group, and the first signal includes an LP-WUS.

[0111] In a possible implementation manner of the fourth aspect, the second position is one or more positions outside the intersection or union of a third position and a fourth position, the third position is determined by the configuration information of the first DRX group, and the fourth position is determined by the configuration information of the second DRX group.

[0112] Based on the above implementation manner, when the second position is one or more positions outside the union of the third position and the fourth position, the time for monitoring the first signal is relatively short, and accordingly, the time for monitoring the PDCCH can be relatively long, so that the network device has enough time to send the PDCCH, thereby reducing the time delay of the terminal device receiving the PDCCH. When the second position is a time domain position outside the intersection of the third position and the fourth position, the time for the network device to send the first signal is relatively long, and accordingly, the time for sending the PDCCH can be relatively short, and the time for the terminal device to turn on the main receiver is relatively short, thereby reducing the power consumption of the terminal device.

[0113] In a possible implementation manner of the fourth aspect, the network device receives third information, the third information comprising at least one of the following: the second quantity of electric energy, the second time delay, support for determining the monitoring position of the first signal according to the configuration information of the first DRX group, support for determining the monitoring position of the first signal according to the configuration information of the second DRX group, support for determining the monitoring position of the first signal according to the configuration information of the first DRX group and the second DRX group, support for the second position being one or more positions outside the intersection of the third position and the fourth position, support for the second position being one or more positions outside the union of the third position and the fourth position, expectation of determining the monitoring position of the first signal according to the configuration information of the first DRX group, expectation of determining the monitoring position of the first signal according to the configuration information of the second DRX group, expectation of determining the monitoring position of the first signal according to the configuration information of the first DRX group and the second DRX group, expectation of the second position being one or more positions outside the intersection of the third position and the fourth position or expectation of the second position being one or more positions outside the union of the third position and the fourth position.

[0150] Please refer to FIG. 1, which is a communication system to which embodiments of the present application apply. The communication system includes a radio access network 100 and a core network 200. Optionally, the communication system can further include an Internet 300 (as an example in FIG. 1).

[0151] The radio access network 100 can include at least one network device and at least one terminal device. For example, the radio access network 100 includes two network devices 110a and 110b and terminal devices 120a to 120j. The network architecture shown in FIG. 1 is only illustrative, and the number of terminal devices and / or network devices can be fewer or more. The communication system described in the embodiments of the present application is for more clearly illustrating the technical solutions of the embodiments of the present application, and does not constitute a limitation on the communication system to which the embodiments of the present application apply. For example, the communication system can further include other devices, such as wireless relay devices and wireless backhaul devices, which are not shown in FIG. 1. Those skilled in the art can know that, as the network architecture evolves, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems. When applying the technical solutions of the embodiments of the present application to other communication systems, the devices, components, modules, etc. in the embodiments can be replaced by corresponding devices, components, modules, etc. in other communication systems, without limitation.

[0152] In the embodiments of the present application, the network device refers to a (radio) access network ((R)AN) device / RAN node. In the embodiments of the present application, the (R)AN and the RAN are replaceable. The RAN can be a third generation partnership project (3GPP) related cellular system, such as a 5G / NR mobile communication system or a future-oriented evolved system (such as a 6G mobile communication system). The RAN can also be an open RAN (O-RAN or ORAN), a cloud radio access network (CRAN), or a virtualized RAN (vRAN), a non-terrestrial network (NTN), etc. The RAN can also be a communication system in which two or more of the above systems are integrated. The RAN device can also be referred to as a RAN node, a RAN entity, or an access node, etc.

[0153] In a possible scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a base station in a future mobile communication system (e.g., a 6G mobile communication system), or the like. The RAN node can be a macro base station, a micro base station, an indoor station, a relay node, a donor node / host node, or a radio controller, or the like. The RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, or the like. For example, the RAN node in a V2X technology can be a road side unit (RSU).

[0154] In another possible scenario, the RAN node can be a module or unit that completes part of the function of a base station, or multiple RAN nodes cooperate to assist a terminal device to implement wireless access, and different RAN nodes respectively implement part of the function of a base station. For example, the RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU), or the like. The function of the CU can be implemented by one entity, or also can be implemented by different entities. For example, the function of the CU can be further divided, that is, the control plane and the user plane are separated and implemented by different entities, respectively, as a control plane CU entity (i.e., a CU-control plane (CP) entity) and a user plane CU entity (i.e., a CU-user plane (UP) entity). The CU-CP entity and the CU-UP entity can be coupled with the DU to jointly complete the function of the RAN node. The CU and the DU can be separately arranged, or also can be included in the same network element, such as a baseband unit (BBU). Any one of the CU (or the CU-CP and the CU-UP), the DU, and the RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0155] In different systems, the CU (or the CU-CP and the CU-UP), the DU, or the RU can also have different names, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the convenience of description, the CU, the CU-CP, the CU-UP, the DU, and the RU are taken as examples for description in this application.

[0156] The CU and the DU can be configured according to protocol layer functions of the wireless network they implement: for example, the CU is configured to implement functions of a packet data convergence protocol (PDCP) layer and above protocol layers (e.g., a radio resource control (RRC) layer and / or a service data adaptation protocol (SDAP) layer, etc.); the DU is configured to implement functions of a protocol layer below the PDCP layer (e.g., a radio link control (RLC), a media access control (MAC) layer, and / or a physical (PHY) layer, etc.). For specific descriptions of the above protocol layers, reference can be made to relevant technical specifications of 3GPP or technical specifications of other applicable communication protocols.

[0157] The above division of processing functions of the CU and the DU according to protocol layers is merely an example, and the division can be made in other manners, which is not limited in the present application. For example, in one design, the CU or the DU can also be divided into partial processing functions of protocol layers. In one design, partial functions of an RLC layer and functions of protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and functions of protocol layers below the RLC layer are arranged in the DU.

[0158] In another possible design, the DU and the RU cooperate to implement functions of the PHY layer, or the design is described as moving part of the PHY layer functions of the DU to the RU. One DU can be connected with one or more RUs. The functions of the DU and the RU can be configured in multiple manners according to design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement intermediate frequency functions. For another example, the DU is configured to implement high-layer functions in the PHY layer, and the RU is configured to implement low-layer functions in the PHY layer or implement the low-layer functions and radio frequency functions. The high-layer functions in the PHY layer can include part of functions of the PHY layer, which are closer to the MAC layer, and the low-layer functions in the PHY layer can include another part of functions of the PHY layer, which are closer to the intermediate frequency side. The present application does not limit specific functions of the DU and the RU. An interface between the DU and the RU can be referred to as a front-haul interface. In one design, the CU can have no PDCP layer, for example, the CU only includes an RRC layer. The CU-CP has no PDCP-C. The CU-UP can have no PDCP-U, or have no CU-UP. In one design, the DU can have no RLC layer, for example, the DU only has a MAC and a higher PHY layer.

[0159] When the RAN is an O-RAN, it can also have an artificial intelligence (AI) function, for example, the O-RAN includes an intelligent controller. The intelligent controller can be a non-real time RAN intelligent controller (non-real time RIC / non-RT RIC / NRT RIC), or a near-real time RAN intelligent controller (near-real time RIC / near-RT RIC / nRT RIC). The non-real time RIC can be used to implement non-real time intelligent management of the RAN function, can implement a workflow including model training and model updating, and guide applications / functions in the nRT RIC based on a policy. The near-real time RIC can be used to implement near-real time intelligent management of the RAN. Through data collection and related operations on the E2 interface, near-real time control and optimization of modules and resources of the O-RAN are implemented.

[0160] In the embodiments of the present application, all devices capable of communicating data with the base station can be regarded as terminal devices. The terminal device is also called terminal, terminal device, user equipment (UE), user device, mobile station, or mobile terminal, etc. The terminal device can be widely applied to various scenarios, for example, the terminal device can be a mobile phone, a computer, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a base station (STA), a mechanical arm, a camera, a robot, a vehicle, a drone, a helicopter, an airplane, a ship, or a smart home device (such as a television, an air conditioner, a sweeping machine, a sound box, a set-top box), a relay, a customer premise equipment (CPE), etc.

[0161] In addition, in the embodiments of the present application, the terminal device can also be a terminal device in an IoT system, for example, a water meter, an electricity meter, etc. IoT is an important part of the future information technology development, and its main technical feature is to connect objects through communication technology and network, so as to realize the intelligent network of man-machine interconnection and object-object interconnection.

[0162] The terminal device can also be referred to as a V2X device when applied to V2X, for example, a smart car, a digital car, an unmanned car, a driverless car, a pilotless car, an automobile, a self-driving car, a pure EV, a Battery EV, a hybrid electric vehicle (HEV), a range extended EV (REEV), a plug-in HEV (PHEV), a new energy vehicle, a road site unit (RSU).

[0163] As introduced above, various terminal devices can be considered as vehicle-mounted terminal devices if they are located on a vehicle (for example, placed / installed in a vehicle). The vehicle-mounted terminal device can be built-in as one or more components or units in a vehicle-mounted module, a vehicle-mounted module group, a vehicle-mounted component, a vehicle-mounted chip or a vehicle-mounted unit of the vehicle, and the vehicle can implement the method of the present application through the built-in vehicle-mounted module, vehicle-mounted module group, vehicle-mounted component, vehicle-mounted chip or vehicle-mounted unit. The vehicle-mounted terminal device can be a whole vehicle device, a vehicle-mounted module, a vehicle, an on board unit (OBU), a roadside unit (RSU), a telematics box (T-box), a chip or a system on chip (SOC), etc. The above chip or SOC can be installed in the vehicle, OBU, RSU or T-box.

[0164] Taking a network device as a base station and a terminal device as a UE as an example, the base station and the UE can be in a fixed position or can be movable.

It should be noted that these explanations are to make the embodiments of the present application easier to understand, and should not be regarded as limiting the scope of protection required by the present application.

[0173] (1) Wake up radio (WUR)

[0174] The wake-up radio can be understood as a function of reducing the power consumption of the terminal device. For the terminal device, the wake-up radio refers to introducing a lower power (LP) interface on the basis of a traditional main radio (MR). The LP interface is implemented by a circuit or a chip with simple structure, and has low power consumption. The specific form of the LP interface is not limited in the embodiments of the present application. For example, the LP interface can be implemented by a wake-up receiver (WUR), an LP-WUR, a low-power radio (LR), a wake-up module or a wake-up circuit. The WUR in the present document can be a wake-up radio or a wake-up receiver. The WUR in the present document can be replaced by an LP-WUR, an LR, a wake-up module or a wake-up circuit.

[0175] The MR is mainly used for data / signaling transmission and / or reception, and can be turned off or in a sleep state or mode if there is no need for data / signaling transmission and / or reception. The WUR can be used to wake up the MR in the sleep state, for example, when there is a need for data / signaling transmission and / or reception, the WUR wakes up the MR. Such design can reduce the power consumption of the terminal device.

[0176] The signal received by the WUR can be referred to as a low-power signal or a low-power wake-up signal (LP-WUS), etc. When the terminal device detects / receives the low-power signal or the LP-WUS, the MR in the sleep state can be woken up. For convenience of description, the low-power signal is taken as the LP-WUS in the present document.

[0177] (2) Type of WUR

[0178] The bit information of the LP-WUS has multiple mapping ways to the time unit, or in other words, the bit information of the LP-WUS has multiple modulation ways. For example, the LP-WUS can adopt OOK modulation, and accordingly, the WUR in the terminal device receives the LP-WUS in the way of envelope detection. For another example, the WUS can also adopt OFDM waveform transmission, and accordingly, the WUR in the terminal device receives the LP-WUS in the way of phase detection. For convenience of description, in the embodiments of the present application, the LP-WUS adopting OFDM waveform transmission is referred to as the LP-WUS adopting OFDM modulation (which will be introduced below).

[0179] The WUR receiving the LP-WUS in a phase detection manner can be regarded as a type of receiver (e.g., referred to as a first type of WUR), and the WUR receiving the LP-WUS in an envelope detection manner can be regarded as another type of WUR (e.g., referred to as a second type of WUR). The first type of WUR and the second type of WUR are relative, and there are multiple interpretations of the first type of WUR and the second type of WUR, which are illustrated below.

[0180] (2.1) The first type of WUR is an OFDM receiver, and the second type of WUR is an OOK receiver.

[0181] (2.2) The first type of WUR is a receiver with both I / Q paths, and the second type of WUR is a receiver with only one of the I / Q paths.

[0182] (2.3) The first type of WUR is a coherent receiver, and the second type of WUR is a non-coherent receiver.

[0183] (2.4) The first type of WUR is a coherent receiver with both I / Q paths, and the second type of WUR is a non-coherent receiver with only one of the I / Q paths.

[0184] (2.5) The first type of WUR receives a signal in a phase detection manner, and the second type of WUR receives a signal in an energy / power / amplitude detection manner. Alternatively, the first type of WUR can / has the ability to detect phase information, and the second type of WUR can / has the ability to detect signal energy / power / amplitude.

[0185] (2.6) The first type of WUR can receive a complex signal, and the second type of WUR cannot receive a complex signal (e.g., the second type of WUR receives a real signal).

[0186] (2.7) The first type of WUR has a phase detection capability, and the second type of WUR has an envelope detection capability or no phase detection capability. Alternatively, the first type of WUR supports receiving a signal in a phase detection manner, and the second type of WUR supports receiving a signal in an envelope detection manner. In an embodiment of the present application, the phase detection capability can be replaced by a correlation detection capability and a sequence detection capability.

[0187] (2.8) The first type of receiver can receive an OFDM signal, and the second type of receiver cannot receive an OFDM signal (e.g., the second type of receiver receives an OOK signal).

[0188] (3) OOK modulation and OFDM modulation

[0189] OOK modulation represents digital information by the presence or absence of a signal. Bit information corresponding to a signal is mapped to at least one time unit through OOK modulation, one time unit corresponds to one bit of information, and the bit information of the signal is determined by detecting whether there is a signal on the time unit. There is a signal on the time unit means that the signal amplitude on the time unit is not zero, such a time unit is also called an ON time unit, or the time unit is in an ON mode; correspondingly, there is a signal on the time unit means that the signal amplitude on the time unit is zero, such a time unit is also called an OFF time unit, or the time unit is in an OFF mode. Generally, if a sequence is sent on a time unit, the time unit has a signal; if no sequence is sent on a time unit, the time unit has no signal. For a time unit, the time unit is an ON time unit or the time unit is in an ON mode, which can be decoded as 1; correspondingly, the time unit is an OFF time unit or the time unit is in an OFF mode, which can be decoded as 0.

[0190] Please refer to FIG. 3, which shows the principle of OOK modulation. FIG. 3 takes the bit information of the signal as 1001 as an example.

[0191] 1001 is mapped to four time units (for example, time unit 1-time unit 4) through OOK modulation. It should be understood that time unit 1 and time unit 4 are time units with signals, and a sequence is sent on time unit 1 and time unit 4. Time unit 2 and time unit 3 are time units without signals, and no sequence is sent on time unit 2 and time unit 3. The receiving end can decode 1 when detecting a sequence on time unit 1 and time unit 4. The receiving end can decode 0 when not detecting a sequence on time unit 2 and time unit 3. The receiving end combines the decoding of the four time units to obtain 1001. It can be seen that for OOK modulation, only one bit of information can be obtained in one time unit. It can be understood that the sequence of the time unit detected by the receiving end means that the receiving end detects the envelope of the signal on the time unit; correspondingly, the sequence of the time unit not detected by the receiving end means that the receiving end does not detect the envelope of the signal on the time unit.

[0192] Please refer to FIG. 4, which shows the principle of OFDM modulation. FIG. 4 takes the sending end storing four sequences (i.e., sequence 1-sequence 4 in the figure) as an example. The four sequences can be used to carry / carry 2 bits of information, for example, sequence 0 corresponds to 00, sequence 1 corresponds to 01, sequence 2 corresponds to 10, and sequence 3 corresponds to 11. In a time unit, the bit information corresponding to the time unit is 01, and the access network device can determine that the sequence 1 corresponding to the bit information 01 according to the correspondence between the four sequences and the bit information. The access network device can scramble the time unit by using the sequence 1.

[0193] As can be seen from FIG. 4, in addition to 1-bit information obtained by the ON / OFF mode in a time unit, sequence information (e.g., 2-bit sequence information in FIG. 4) of the ON time unit can also be detected. Compared with OOK modulation, OFDM modulation can obtain more bit information. Therefore, based on OFDM modulation, if a signal of the same length of bit information is to be transmitted, the signal occupies less time domain resource than OOK modulation. For example, a signal of the same length of bit information needs M symbols based on OFDM modulation, and needs N symbols based on OOK modulation, M is less than N, and M and N are positive numbers.

[0194] The modulation mode used by the signal depends on the capability of the receiver. Taking the foregoing WUR as an example, if the WUR is the first type of WUR, the bit information of the LP-WUS can be carried by the ON / OFF mode of the symbol and the sequence on the ON symbol. If the WUR is the second type of WUR, the bit information of the LP-WUS can be carried by the ON / OFF mode of the symbol. The signal corresponding to the first type of WUR is referred to as a type of signal (e.g., referred to as a first type of signal), and the signal corresponding to the second type of WUR is referred to as another type of signal (e.g., referred to as a second type of signal). Since the second type of WUR needs to occupy more time domain resources than the first type of WUR, the second type of signal is longer than the first type of signal, and the second type of signal can be referred to as a “long signal”, and the first type of signal can be referred to as a “short signal”. The first type of signal can also be referred to as a first type of low-power signal or a first type of LP-WUS, and correspondingly, the second type of signal can also be referred to as a second type of low-power signal or a second type of LP-WUS. Relatively, the power consumption of the second type of WUR receiver required for the second type of signal is greater than the power consumption of the first type of WUR receiver required for the first type of signal. The terminal device has greater energy saving gain when receiving the first type of signal by the first type of WUR. In addition, the detection performance of the second type of WUR is less than the detection performance of the first type of WUR, and the coverage performance supported by the second type of WUR is less than the coverage performance supported by the first type of WUR. Generally, if the second type of WUR is used to receive the signal, the coverage performance can be increased by coverage enhancement technology. For example, for the second type of WUR, the coverage performance can be improved by increasing the number of repeated transmissions of the signal.

[0195] (4) Low-power signal

[0196] In addition to the LP-WUS, embodiments of the present application do not limit the type of low power signal. For example, the low power signal can be a low power physical downlink control channel (PDCCH), a low power physical downlink shared channel (PDSCH), a low power physical uplink shared channel (PUSCH), a low power physical uplink control channel (PUCCH), a low power synchronization signal / physical broadcast channel block (SSB), a low power synchronization signal, a low power tracking reference signal (TRS), a low power channel status information reference signal (CSI-RS), a low power positioning signal, a low power sensing communication signal, a low power sounding reference signal (SRS) signal, a low power random access channel (RACH) signal, a low power preamble signal, a low power contention resolution message, a low power downlink control information (DCI) signal, or a low power uplink control information (UCI) signal, etc. The size of the bit information of the low power signal is determined by one or more of the following: a physical layer, a core network, a medium access control (MAC) layer, a radio link control (RLC) layer, a packet data convergence protocol (PDCP) layer, a service data adaptation protocol (SDAP) layer, a radio resource control (RRC) layer, or a core network.

[0197] (5) Time unit

[0198] In the embodiments of the present application, the time unit refers to the unit of time. The time unit can be a radio frame, a subframe, a slot, a mini-slot, an OFDM symbol, an hour, a minute, a second, a millisecond, a partial OFDM symbol, an OOK symbol, an OOK time unit, or a time unit of a fraction of a millisecond (for example, 1 / 32 ms). Alternatively, the time unit is a plurality of radio frames, a plurality of subframes, a plurality of slots, a plurality of mini-slots, a plurality of OFDM symbols, a number of hours, a number of minutes, a number of seconds, a number of milliseconds, a plurality of partial OFDM symbols, a plurality of OOK symbols, a plurality of OOK time units, or a number of fractions of a millisecond. Among them, one radio frame can include a plurality of subframes, one subframe can include one or more slots, and one slot can include at least one OFDM symbol. Alternatively, one radio frame can include a plurality of slots, and one slot can include at least one OFDM symbol. For the convenience of distinction, in the embodiments of the present application, the time unit mapped through OOK modulation is referred to as an OOK time unit, and one OFDM symbol can include one or more OOK time units. The OOK time unit in the ON mode is also referred to as an OOK ON time unit. The OOK time unit can also be referred to as an OOK symbol.

[0199] (6) In the present application, the band is an exemplary expression, which can be understood as a cell, a frequency point, and the "cell" can be understood as a "cell frequency point", a "carrier frequency", a "carrier frequency point", a "frequency point", which can be replaced with each other unless otherwise specified. The frequency point can be a center frequency point, a carrier frequency, a frequency position corresponding to a frequency number, a center of a frequency band, a wave band, a band, a center of a bandwidth, a frequency position, a center frequency of a bandwidth part, or a center of a bandwidth part.

[0200] As described above, the power consumption of the terminal device has a great influence on the endurance and service life of the terminal device. In order to reduce power consumption, the terminal device can activate the low-power wake-up signal (LP-WUS) function. In the case of not needing to receive a paging message or not having data transmission, the terminal device turns on the LP-WUR, and the power consumption of the LP-WUR is lower than that of the main receiver. After turning on the LP-WUR, the terminal device can monitor the LP-WUS through the LP-WUR. When the LP-WUS is received, the terminal device needs to turn on the main receiver to receive the paging message or transmit data. However, when the terminal device is configured with multiple DRX groups, for example, two DRX groups, the terminal device cannot determine the position of monitoring the LP-WUR, which may cause the terminal device to fail to receive the LP-WUS in time, and further cause the time delay of the terminal device to receive data to be too large.

[0201] For example, please refer to FIG. 5-1, the terminal device is configured with two DRX groups, i.e., DRX group #1 and DRX group #2. The LP-WUS is deployed on one of the DRX group #1 and the DRX group #2. The LP-WUS triggers the monitoring PDCCH of one of the DRX group #1 and the DRX group #2. Taking the LP-WUS deployed on the DRX group #1 as an example, when the terminal device receives the LP-WUS, the LP-WUS triggers the band monitoring PDCCH of the DRX group #1, or triggers the band monitoring PDCCH of the DRX group #2.

[0202] For example, please refer to FIG. 5-2, the terminal device is configured with two DRX groups, i.e., DRX group #1 and DRX group #2. The LP-WUS is deployed on one of the DRX group #1 and the DRX group #2. The LP-WUS triggers the band monitoring PDCCH of the DRX group #1 and the band monitoring PDCCH of the DRX group #2. Taking the LP-WUS deployed on the DRX group #1 as an example, when the terminal device receives the LP-WUS, the LP-WUS triggers the band monitoring PDCCH of the DRX group #1 and the band monitoring PDCCH of the DRX group #2.

[0203] In FIG. 5-1 and FIG. 5-2, the configuration information of the DRX group #1 and the DRX group #2 is different, and the LP-WUS deployed in one DRX group can trigger the band monitoring PDCCH of the other DRX group. For example, in FIG. 5-1, the LP-WUS deployed in the DRX group #1 can trigger the band monitoring PDCCH of the DRX group #2, and in FIG. 5-2, the LP-WUS deployed in the DRX group #2 can trigger the band monitoring PDCCH of the DRX group #1. At this time, the terminal device cannot determine whether to determine the monitoring position of the LP-WUS according to the configuration information of the DRX group 1 or the configuration information of the DRX group #2.

[0204] The above technical solution can know that when the terminal device is configured with the configuration information of multiple DRX groups, the terminal device cannot determine the monitoring position of the LP-WUR, which can cause the terminal device to fail to receive the LP-WUS in time, and further cause the time delay of the terminal device to receive data to be too large. Therefore, the present application provides related technical solutions, please refer to the related introduction of the embodiments in the following.

[0205] The technical scheme provided in the present application is applicable to a communication system including a terminal device and a network device. For example, when the technical scheme provided in the present application is applied to the communication system shown in FIG. 1, the terminal device can be one or more of terminal devices 120a to 120j, and the network device can be one or more of network devices 110a and 110b. For example, when the technical scheme provided in the present application is applied to the communication system shown in FIG. 2, the terminal device can be one or more of terminal device 240 and terminal device 230, and the network device can be wireless access network device 220.

[0206] In the embodiments of the present application, the execution subject can be a terminal device, a network device, a communication module in the terminal device or the network device, or a circuit or chip responsible for a communication function in the terminal device. Hereinafter, the execution subject is taken as a terminal device and a network device for example. When the execution subject is a communication module, a circuit or a chip in the terminal device or the network device, the receiving (or monitoring) / sending can be understood as input / output, that is, the communication module, the circuit or the chip communicates with other components in the terminal device or the network device. In addition, the processing performed by a single execution subject can also be divided into processing performed by multiple execution subjects, which can be logically and / or physically separated. For example, the processing performed by the network device can be divided into processing performed by at least one of a CU, a DU, and an RU.

[0233] Optionally, as shown in FIG. 7, the terminal device receives a first signal at a first time. The first signal indicates whether the terminal device needs to monitor the PDCCH in the length of the first timer after the gap. The time when the gap starts is the first time, and the time when the gap ends is the second time. Assuming that the first signal indicates that the terminal device monitors the PDCCH, the time when the gap ends, i.e., the second time, is the time when the terminal device starts to monitor the PDCCH, the length of the first timer is the duration of monitoring the PDCCH, and also the duration of not monitoring the first signal. The duration of the interval between the second time and the third time in FIG. 7 is the length of the first timer, and the terminal device stops monitoring the PDCCH at the third time. The first position of monitoring the first signal is one or more positions other than the position corresponding to the first timer. As can be seen, the position of not monitoring the first signal can be determined according to the length of the first timer, and the first position of monitoring the first signal can be determined accordingly.

[0234] Optionally, the value of the gap depends on the sleep state of the main receiver of the terminal device during monitoring of the first signal. For example, when the main receiver of the terminal device is in a micro-sleep state, the gap is 0; when the main receiver of the terminal device is in a light-sleep state, the gap is 6 ms; and when the main receiver of the terminal device is in a deep-sleep state, the gap is 20 ms.

[0235] Optionally, the value of the gap also depends on the time required for the terminal device to synchronize. For example, when the terminal device needs to receive 1 SSB for synchronization, the gap also needs to include the time required for the terminal device to receive 1 SSB after waking up the main receiver of the terminal device; and when the terminal device needs to receive 2 SSBs for synchronization, the gap also needs to include the time required for the terminal device to receive 2 SSBs after waking up the main receiver of the terminal device.

[0236] Optionally, the terminal device can determine, according to the first information, to use the length of the first timer of the first DRX group, or to use the length of the first timer of the second DRX group, or to use the length of the first timer of the first DRX group and the second DRX group. Wherein, “using the length of the first timer of the first DRX group” means determining the first position of monitoring the first signal according to the length of the first timer of the first DRX group, “using the length of the first timer of the second DRX group” means determining the first position of monitoring the first signal according to the length of the first timer of the second DRX group, and “using the length of the first timer of the first DRX group and the second DRX group” means determining the first position of monitoring the first signal according to the length of the first timer of the first DRX group and the length of the first timer of the second DRX group. For example, according to the first information, the union of the first timer of the first DRX group and the first timer of the second DRX group is determined. For example, according to the first information, the intersection of the first timer of the first DRX group and the first timer of the second DRX group is determined.

[0237] Optionally, the position corresponding to the first timer comprises a position from the second time point to the third time point. As described above, the second time point is the time point at which the PDCCH is started to be monitored, and the length of time interval between the second time point and the third time point is the length of the first timer. Taking FIG. 8 as an example, the second time point is time point B, the third time point is time point C or time point D, the length of time interval between the time point B and the time point C is the length of the first timer of the first DRX group, and thus the position corresponding to the first timer of the first DRX group is the position from the time point B to the time point C. The length of time interval between the time point B and the time point D is the length of the first timer of the second DRX group, and thus the position corresponding to the first timer of the second DRX group is the position from the time point B to the time point D.

[0238] Optionally, if the PDCCH is monitored by the terminal device during the first timer, the second timer is started. After the second timer is started, the length of time for monitoring the PDCCH can be extended.

[0239] Optionally, the second timer comprises a drx-inactivityTimer.

[0240] Optionally, the second timer can be a second timer of the first DRX group and / or a second timer of the second DRX group.

[0241] Optionally, the terminal device can determine, according to the first information, to use the length of the second timer of the first DRX group, or to use the length of the second timer of the second DRX group, or to use the length of the second timer of the first DRX group and the second DRX group. For example, when the length of the second timer of the first DRX group and the second DRX group is used, the second timer can be the intersection or the union of the second timer of the first DRX group and the second timer of the second DRX group.

[0242] Optionally, when the first signal indicates that the terminal device monitors the PDCCH, the first position can be one or more positions other than the position corresponding to the first timer. Taking FIG. 8 as an example, if the terminal device receives the LP-WUS at time A, the LP-WUS indicates that the PDCCH needs to be monitored. Assuming that the main receiver is in a deep sleep state, the PDCCH needs to be monitored after a gap, and assuming that the end time of the gap is time B, the terminal device starts to monitor the PDCCH from time B. In FIG. 8, the terminal device ends to monitor the PDCCH at time C on the first DRX group, the interval between time B and time C is the length of the first timer of the first DRX group, and the terminal device ends to monitor the PDCCH at time D on the second DRX group, the interval between time B and time D is the length of the first timer of the second DRX group. When the length of the first timer of the first DRX is used, the first position for monitoring the first signal is one or more positions other than the position from time B to time C, and when the length of the first timer of the second DRX is used, the first position for monitoring the first signal is one or more positions other than the position from time B to time D.

[0243] Optionally, when the first signal indicates that the terminal device does not monitor the PDCCH, the first position can include one or more positions in the position corresponding to the first timer. Taking FIG. 8 as an example, for the first DRX group, at time A, the terminal device receives the first signal, which indicates that the PDCCH does not need to be monitored, and then the terminal device monitors the first signal at position 1 and position 2, that is, the first position for monitoring the first signal includes position 1 and position 2.

[0244] Optionally, the terminal device determines the position for monitoring the first channel according to the first information, or the terminal device determines the time domain position for monitoring the first channel according to the first information, or the terminal device determines the frequency domain position for monitoring the first channel according to the first information, or the terminal device determines the time domain resource for monitoring the first channel according to the first information, or the terminal device determines the frequency domain resource for monitoring the first channel according to the first information, or the terminal device determines the time length for monitoring the first channel according to the first information, or the terminal device determines the length of the first timer for monitoring the first channel according to the first information, or the terminal device monitors the first channel according to the first information, wherein the first channel includes the PDCCH or the PDSCH.

[0245] In order to help understand the above S601 and S602, a few examples are given:

[0246] For example, the terminal device determines, according to the first information, that the configuration information of the first DRX group needs to be used, that is, the first position for monitoring the first signal needs to be determined according to the configuration information of the first DRX group, and for example, the configuration information of the first DRX group is the length of the first timer of the first DRX group, and the terminal device can determine the first position according to the length of the first timer of the first DRX group. For example, in FIG. 8, at time A, the terminal device receives the first signal, and assuming that the main receiver is in a light sleep state or a deep sleep state, it is necessary to start monitoring the PDCCH after a gap period, and assuming that the end time of the gap is time B, the terminal device starts monitoring the PDCCH from time B. At this time, the terminal device can determine the time of ending monitoring the PDCCH according to the length of the first timer of the first DRX group, that is, the time C of ending monitoring the PDCCH is the time interval between time B and time C. The length of the first timer of the first DRX group is the first position for monitoring the first signal, which is one or more positions other than the position from time B to time C, for example, positions 3 and / or 4. Then the terminal device monitors the first signal at positions 3 and / or 4.

[0247] For another example, the terminal device determines, according to the first information, that the configuration information of the second DRX group needs to be used, that is, the first position for monitoring the first signal needs to be determined according to the configuration information of the second DRX group, and for example, the configuration information of the second DRX group is the length of the first timer of the second DRX group, and the terminal device can determine the first position according to the length of the first timer of the second DRX group. For example, in FIG. 8, at time A, the terminal device receives the first signal, and assuming that the main receiver is in a light sleep state or a deep sleep state, it is necessary to start monitoring the PDCCH after a gap period, and assuming that the end time of the gap is time B, the terminal device starts monitoring the PDCCH from time B. At this time, the terminal device can determine the time of ending monitoring the PDCCH according to the length of the first timer of the second DRX group, that is, the time D of ending monitoring the PDCCH is the time interval between time B and time D. The length of the first timer of the second DRX group is the first position for monitoring the first signal, which is one or more positions other than the position from time B to time D, for example, positions 5, 6 and / or 7. Then the terminal device monitors the first signal at positions 5, 6 and / or 7.

[0248] For example, the terminal device determines, according to the first information, that the configuration information of the first DRX group and the second DRX group needs to be used, that is, the first position for monitoring the first signal needs to be determined according to the configuration information of the first DRX group and the second DRX group, and that the length of the first timer of the first DRX group is taken as the configuration information of the first DRX group, and the length of the first timer of the second DRX group is taken as the configuration information of the second DRX group. According to the length of the first timer of the first DRX group and the length of the first timer of the second DRX group, the terminal device can determine the first position. For example, the first position can be a union, that is, the union of the position corresponding to the first timer of the first DRX group and the position corresponding to the first timer of the second DRX group. Since in FIG. 8, the union of the position corresponding to the first timer of the first DRX group and the position corresponding to the first timer of the second DRX group is the position corresponding to the first timer of the first DRX group, the terminal device ends monitoring the PDCCH at time C, which is the length of the first timer of the first DRX group, between time B. The first position for monitoring the first signal is one or more positions other than the position from time B to time C, for example, position 3 and / or position 4. Then the terminal device monitors the first signal at position 3 and / or position 4.

[0249] Based on the scheme shown in FIG. 6, the terminal device can determine the monitoring position of the first signal. Taking the first signal as an example, the scheme of FIG. 6 can solve the problem of being unable to determine the monitoring position of the LP-WUS. Since the terminal device determines the monitoring position of the LP-WUS based on the first information, and the first information can be indication information, service information, or the working frequency point of the LP-WUS, the finally determined monitoring position of the LP-WUS is adapted to the indication information, service information, or the working frequency point of the LP-WUS. Taking the first information as an example, the service information, determining the monitoring position of the LP-WUS according to the service information can make the monitoring of the LP-WUS adapt to the service situation and reduce the delay of receiving the PDCCH. For example, when the service information is that the device corresponding to the first DRX group transmits, it indicates that there is service on the first DRX group. Therefore, the first position can be related to the first DRX group, for example, the first position can be related to the configuration information of the first DRX group. Therefore, the terminal device can timely receive the LP-WUS transmitted on the first DRX group at the first position. When there is PDCCH to be received, since the LP-WUS can trigger the terminal device to monitor the PDCCH, the PDCCH can be timely received, that is, the delay of receiving the PDCCH can be reduced, and the delay of data transmission can be further reduced.

[0250] For the first information, the present application provides a plurality of optional examples:

[0251] Example a1: the first information is first indication information.

[0252] In an optional implementation, the network device sends first indication information, the first indication information being used for indicating at least one of the following: the first DRX group, the second DRX group or the first position. Correspondingly, the terminal device receives the first indication information.

[0253] In the above implementation, the network device can indicate the first position at which the terminal device monitors the first signal or indicate the DRX group to be adopted through the first indication information, so that the network device can control the position at which the terminal device monitors the first signal, so as to make the position at which the terminal device monitors the first signal match the position at which the network device sends the first signal, or match the service information or service requirement obtained by the network device, etc.

[0254] Optionally, the example a1 can be applied to a carrier aggregation scenario, in which case, the serving cell set of the terminal device can include a primary cell (PCell) and a secondary cell (SCell), wherein the primary cell can correspond to the first DRX group and the secondary cell can correspond to the second DRX group.

[0255] Optionally, the first indication information includes at least one of the following: an identifier of the first DRX group, an identifier of the second DRX group, a length of the first timer of the first DRX group, a length of the first timer of the second DRX group, a time length corresponding to the first position, a time domain resource corresponding to the first position or a time domain position corresponding to the first position.

[0256] For example, 2 bits in the first indication information can be used to carry the identifier of the first DRX group, the identifier of the second DRX group or the identifiers of the first DRX group and the second DRX group. For example, the first bit and the second bit in the first indication information are 00, wherein 00 is the identifier of the first DRX group, so the first indication information is used to indicate the first DRX group. For example, the first bit and the second bit in the first indication information are 11, wherein 11 is the identifier of the second DRX group, so the first indication information is used to indicate the second DRX group. For example, the first bit and the second bit in the first indication information are 10, wherein 10 is the identifier of the first DRX group and the second DRX group, so the first indication information is used to indicate the first DRX group and the second DRX group.

[0257] For another example, the first indication information can be 10 time slots, i.e., indicating that the length of the first timer is 10 time slots, i.e., indicating that the time length for the terminal device to monitor the PDCCH is 10 time slots, and the time length for the terminal device not to monitor the first signal is 10 time slots. For example, the terminal device receives an LP-WUS at time slot C, the LP-WUS indicating to monitor the PDCCH, and the time domain position from time slot C to after 10 time slots is position A, and the first position is one or more positions other than position A.

[0258] Optionally, the first indication information can be high-layer signaling, such as RRC signaling, such as MAC CE signaling; or the first indication information can be physical-layer signaling, such as DCI; or the first indication information can be carried in a data channel, such as PDSCH.

[0259] Optionally, when the first indication information indicates the first DRX group, the first position is related to the first DRX group, when the first indication information indicates the second DRX group, the first position is related to the second DRX group, and when the first indication information indicates the first DRX group and the second DRX group, the first indication information is related to the first DRX group and the second DRX group.

[0260] Optionally, the network device can determine the first indication information according to at least one or more of the following optional manners:

[0261] Manner 1a: the network device determines the first indication information according to information of the first service.

[0262] In manner 1a, the network device can adjust the position of the terminal device monitoring the first signal according to the situation of the first service, can reduce the time delay of receiving information or a channel, and reduce power consumption. For example, when the data packet of the first service is large, the first DRX group with a longer length of the first timer can be selected, that is, the first position of monitoring the first signal is determined according to the configuration information of the first DRX group, so as to ensure that the time of monitoring PDCCH is long enough to reduce the time delay of receiving PDCCH, when the data packet of the first service is small, the second DRX group with a shorter length of the first timer can be selected, that is, the first position of monitoring the first signal is determined according to the configuration information of the second DRX group, so that the time of monitoring PDCCH is short, and the time of turning on the main receiver is short, so the power consumption can be reduced.

[0263] Optionally, the first service can be a service sent by the network device or a service to be transmitted by the terminal device.

[0264] Optionally, the information of the first service includes the size of the data packet of the first service. For example, when the size of the data packet of the first service is greater than a threshold A, the DRX group with a longer length of the first timer, that is, the first DRX group, can be selected. The first indication information is used to indicate the first DRX group, so that the network device can determine the first position according to the configuration information of the first DRX group.

[0265] Manner 1b: the network device determines the first indication information according to the second information sent by the terminal device.

[0266] In an optional implementation, the terminal device sends second information, which includes at least one of the following: the second power, the second time delay, configuration information of a supported DRX group, a supported monitoring position of the first signal, configuration information of an expected DRX group, or an expected monitoring position of the first signal. Correspondingly, the network device receives the second information.

[0267] In mode 1b, the network device can determine the first position for monitoring the first signal according to the second power or the second time delay sent by the terminal device. For example, when the network device determines the first position for monitoring the first signal according to the second power, the first position for monitoring the first signal is finally adapted to the power of the terminal device, thereby saving the power or power consumption; for example, when the network device determines the first position for monitoring the first signal according to the second time delay, the first position for monitoring the first signal is finally adapted to the time delay expected or supported by the terminal device, thereby reducing the time delay of data transmission.

[0268] Optionally, the second power can be the remaining power of the terminal device. The second power can also be replaced by other parameters related to the remaining power, for example, the remaining working time of the terminal device estimated by the remaining power.

[0269] Optionally, the time delay in the present application is a simplified description, and the time delay in the present application refers to a packet delay threshold (PDB).

[0270] Optionally, the second time delay includes a time delay supported by the terminal device, a time delay expected by the terminal device, or a time delay allowed by the terminal device.

[0271] Optionally, the second information is reported through terminal capability information of the terminal device, and the terminal capability information of the terminal device includes configuration information of a supported DRX group or a supported monitoring position of the first signal.

[0272] Optionally, the second information is reported through terminal assistance information of the terminal device, and the terminal assistance information of the terminal device includes configuration information of an expected DRX group or an expected monitoring position of the first signal.

[0273] Optionally, when the second power is less than a third threshold, the first position is determined by configuration information of the second DRX group, and the configuration information of the second DRX group includes a length of a first timer of the second DRX group, and a length of a first timer of the first DRX group is greater than the length of the first timer of the second DRX group.

[0274] Optionally, when the second time delay is less than a fourth threshold value, the first position is determined by configuration information of the first DRX group, and the configuration information of the first DRX group includes a length of a first timer of the first DRX group, and the length of the first timer of the first DRX group is greater than a length of a first timer of the second DRX group.

[0275] Optionally, the second information can further include a size of a cache space or a storage space available to the terminal device. For example, the terminal device can send the second information to the network device, and the second information indicates that the size of the cache space or the storage space available to the terminal device is less than a threshold value B, and then the terminal device can use a smaller space to cache or store the PDCCH. Accordingly, the network device can determine that the DRX group with a shorter length of the first timer, i.e., the second DRX group, is needed, and the network device can send the first indication information for indicating the second DRX group, so that the terminal device monitors the first information and / or the first channel according to the configuration information of the second DRX group, and the network device sends the first information and / or the first channel according to the configuration information of the second DRX group.

[0276] Optionally, the terminal device can determine the first indication information according to the second information and the information of the first task, i.e., the first indication information can be determined in combination with the second information and the information of the first task.

[0277] Example a2: the first information is service information.

[0278] In an optional implementation, when the terminal device receives the service information sent by the first device, the first position is related to the configuration information of the first DRX group of the first device; or, when the terminal device receives the service information sent by the second device, the first position is related to the configuration information of the second DRX group of the second device; or, when the terminal device receives the service information sent by the first device and the second device, the first position is related to the configuration information of the first DRX group of the first device and / or the configuration information of the second DRX group of the second device.

[0279] In example a2, when the first device has service information transmission, the first position is related to the configuration information of the first DRX group, when the second device has service information transmission, the first position is related to the configuration information of the second DRX group. When the first device and the second device both have service information transmission, the first position is related to the configuration information of the first DRX group and the configuration information of the second DRX group. That is, the first position can be adjusted based on the configuration information of the DRX group flexibly according to whether the first device and / or the second device has service information transmission, so that the position of monitoring the first signal is matched with the service situation, and excessive power consumption or excessive time delay is avoided.

[0280] Optionally, the network device can comprise the first apparatus and / or the second apparatus. That is, the first apparatus and the second apparatus can also perform the foregoing S601 and S602 and the related steps or methods.

[0281] Optionally, the example a2 can be applied to a scenario of dual connectivity (DC), in which the terminal device is connected to the first apparatus and the second apparatus simultaneously, or the terminal device is connected to two wireless systems.

[0282] Optionally, when the terminal device receives the service information sent by the first apparatus, the first position for monitoring the first signal can be determined according to the configuration information of the first DRX group.

[0283] Optionally, when the terminal device receives the service information sent by the second apparatus, the first position for monitoring the first signal can be determined according to the configuration information of the second DRX group.

[0284] Optionally, when the terminal device receives the service information sent by the first apparatus and the second apparatus, the first position for monitoring the first signal can be determined according to the configuration information of the first DRX group and the configuration information of the first DRX group. For example, the first position can be one or more positions outside the union or intersection of the position C and the position D. Taking FIG. 8 as an example, the position C is the position corresponding to the first timer of the first DRX group, that is, the time point B to the time point C, and the position D is the position corresponding to the first timer of the second DRX group, that is, the time point B to the time point D. In FIG. 8, the union of the position C and the position D is the position C, and the intersection of the position C and the position D is the position D. When the first position is one or more positions outside the union of the position C and the position D, the first position can be the position 3 and / or the position 4, and when the first position is one or more positions outside the intersection of the position C and the position D, the first position can be the position 5, the position 6 and / or the position 7.

[0285] For the DC scenario, as described above, when the terminal device receives the service information sent by the first apparatus and the second apparatus, the first position for monitoring the first signal is related to the configuration information of the first DRX group of the first apparatus and / or the configuration information of the second DRX group of the second apparatus. For the network device, the first position for sending the first signal can be the same as or different from the first position for the terminal device to monitor the first signal, which will be described in detail below.

[0286] In an optional implementation, the first position for the network device to send the first signal is determined according to the configuration information of the first DRX group and / or the configuration information of the second DRX group.

[0287] Based on the above implementation manner, the network device can determine the first position for sending the first signal according to the configuration information of the first DRX group, or determine the first position for sending the first signal according to the configuration information of the second DRX group, or the network device can determine the first position for sending the first signal according to the configuration information of the first DRX group and the configuration information of the second DRX group, that is, the network device can flexibly determine the first position for sending the first signal based on the configuration information of any one or more DRX groups, without being limited by the configuration information of the DRX group based on the terminal device.

[0288] Optionally, when the terminal device monitors one or more positions of the union of the first position C and the first position D, the network device can determine the first position for sending the first signal according to the configuration information of the first DRX group, or according to the configuration information of the second DRX group, or according to the first DRX group and the second DRX group. Optionally, which configuration information of the DRX group is used can be determined by the network device according to the information of the first service, or the network state or device state of the network device.

[0289] Example a3: The first information is the operating frequency point of the first signal.

[0290] In an optional implementation manner, the first position is related to the configuration information of the DRX group of the operating frequency point of the first signal.

[0291] In the above implementation manner, the terminal device can determine the first position for monitoring the first signal according to the configuration information of the DRX group of the operating frequency point of the first signal, so that the finally determined first position for monitoring the first signal is adapted to the configuration information of the DRX group corresponding to the first signal, and thus the finally determined first position for monitoring the first signal is adapted to the service condition.

[0292] Optionally, example a3 can be used in a CA scenario, and can also be used in a DC scenario.

[0293] Optionally, the first signal can include a plurality of signals, the first device receives a signal A in the plurality of signals, and the first device can determine the first position for subsequently monitoring other first signals according to the operating frequency point of the signal A. The other first signals refer to signals in the first signals that are transmitted later than the signal A. For example, when the first device receives an Nth signal in the first signals, where N≥1, the terminal device can determine the first position for subsequently monitoring an N+1th signal in the first signals according to the operating frequency point of the Nth signal.

[0294] Optionally, when the network device corresponds to the first DRX group, and the operating frequency point of the network device includes the operating frequency point of the first signal, the first position is related to the configuration information of the first DRX group of the network device.

[0295] Optionally, when the network device corresponds to the second DRX group and the working frequency point of the network device includes the working frequency point of the first signal, the first position is related to the configuration information of the second DRX group of the network device.

[0296] Optionally, when the band corresponding to the first DRX group includes the working frequency point of the first signal, the first position is related to the configuration information of the first DRX group.

[0297] Optionally, when the band corresponding to the second DRX group includes the working frequency point of the first signal, the first position is related to the configuration information of the second DRX group.

[0298] Example a4: The first information is the first power or the first time delay.

[0299] In example a4, the terminal device considers the first power and the first time delay when determining the first position of the first signal, so that the monitoring of the first position of the first signal can be adapted to the first power of the terminal device as much as possible, thereby saving the power consumption, or the monitoring of the first position of the first signal can be adapted to the first time delay of the terminal device as much as possible, thereby reducing the time delay of data transmission.

[0300] Optionally, example a4 can be used in a CA scenario, and can also be used in a DC scenario.

[0301] Optionally, the first power can be the remaining power of the terminal device. The first power can also be replaced by other parameters related to the remaining power, for example, the remaining working time of the terminal device estimated by the remaining power.

[0302] Optionally, the first time delay includes: a time delay supported by the terminal device, a time delay expected by the terminal device, or a time delay allowed by the terminal device.

[0303] Optionally, the first time delay can be the same as or different from the second time delay.

[0304] Optionally, the terminal device can first determine the configuration information of the first DRX group, the configuration information of the second DRX group, or the configuration information of the first DRX group and the second DRX group according to the first power or the first time delay. Then, the terminal device sends second indication information to the network device, where the second indication information is used to indicate the first DRX group, the second DRX group, or the first DRX group and the second DRX group. For example, when the terminal device determines the configuration information of the first DRX group, the second indication information is used to indicate the first DRX group. After receiving the second indication information, the network device can agree or disagree to use the configuration information of the DRX group indicated by the second indication information. For example, the network device can determine whether to use the configuration information of the DRX group indicated by the second indication information according to the status of the network device, the network status, or the information of the first service. Subsequently, the network device sends the first indication information, which can be used to indicate the first DRX group, the second DRX group, or the first position, and the specific indication can be determined by the network device according to the status of the network device, the network status, and the like. In other words, the terminal device can determine the configuration information of a certain DRX group according to the first time delay or the first power, and report the configuration information to the network device, but the network device can agree or disagree to use the configuration information of the DRX group reported by the terminal device, that is, the final determination of the configuration information of the DRX group is determined by the network device. Optionally, before the final determination of the first position for monitoring the first signal, the terminal device and the network device can negotiate through signaling or information, for example, through the second indication information and the first indication information.

[0305] Referring to FIG. 9, another implementation of the communication method provided by the present application is shown, which includes the following steps.

[0306] S901. The terminal device monitors the first signal at at least one of the second positions. Correspondingly, the network device sends the first signal at at least one of the second positions.

[0307] The second positions are determined by the configuration information of the first DRX group and the configuration information of the second DRX group, and the first signal includes the LP-WUS.

[0308] In the method shown in FIG. 9, the terminal device comprehensively considers the configuration information of the first DRX group and the configuration information of the second DRX group, and determines the second positions for monitoring the first signal based on both. Thus, it can be avoided that the first signal cannot be received or cannot be received in time due to the omission of part of the monitoring positions, and thus the main receiver of the terminal device cannot be woken up in time, resulting in that the PDCCH data cannot be received in time.

[0309] Optionally, the configuration information of the DRX group (e.g., the first DRX group and the second DRX group) includes a length of a first timer, the first timer including an onDurationTimer, a drx-inactivitytimer, or other timers.

[0310] Optionally, the network device can configure the onDurationTimer and / or the drx-inactivitytimer to the terminal device through RRC signaling.

[0311] Optionally, the second position can be determined according to the first timer of the first DRX group, the second position can be determined according to the first timer of the second DRX group, and the second position can be determined according to the first timer of the first DRX group and the first timer of the second DRX group.

[0312] Optionally, the second position in the method shown in FIG. 9 can be the same as or different from the first position in the method shown in FIG. 8.

[0313] In an optional implementation, the second position is one or more positions outside an intersection or a union of a third position and a fourth position, the third position being determined by the configuration information of the first DRX group, and the fourth position being determined by the configuration information of the second DRX group. For example, the third position and the fourth position are the first timers.

[0314] In the above implementation, when the second position is one or more positions outside the union of the third position and the fourth position, the time for monitoring the first signal is shorter, and accordingly, the time for monitoring the PDCCH can be longer, so that the PDCCH can be received in time, and the time delay for receiving the PDCCH is reduced. When the second position is one or more positions outside the intersection of the third position and the fourth position, the time for monitoring the first signal is longer, and accordingly, the time for monitoring the PDCCH can be shorter, that is, the time for turning on the main receiver is shorter, so that the power consumption can be reduced.

[0315] To help understand the above implementation, taking FIG. 8 as an example, the third position is a position corresponding to the first timer of the first DRX group, that is, the time point B to the time point C, and the fourth position is a position corresponding to the first timer of the second DRX group, that is, the time point B to the time point D. In FIG. 8, the union of the third position and the fourth position is the third position, and the intersection of the third position and the fourth position is the fourth position. When the second position is one or more positions outside the union of the third position and the fourth position, the second position can be position 3 and / or position 4. When the second position is one or more positions outside the intersection of the third position and the fourth position, the second position can be position 5, position 6, and / or position 7.

[0316] In an optional implementation, the terminal device sends third information, which includes at least one of the following: the second power consumption, the second time delay, support for determining the monitoring position of the first signal according to the configuration information of the first DRX group, support for determining the monitoring position of the first signal according to the configuration information of the second DRX group, support for determining the monitoring position of the first signal according to the configuration information of the first DRX group and the second DRX group, support for the second position being one or more positions outside the intersection of the third position and the fourth position, support for the second position being one or more positions outside the union of the third position and the fourth position, expectation of determining the monitoring position of the first signal according to the configuration information of the first DRX group, expectation of determining the monitoring position of the first signal according to the configuration information of the second DRX group, expectation of determining the monitoring position of the first signal according to the configuration information of the first DRX group and the second DRX group, and expectation of the second position being one or more positions outside the intersection of the third position and the fourth position or expectation of the second position being one or more positions outside the union of the third position and the fourth position. Correspondingly, the network device receives the third information.

[0317] Based on the above implementation, the terminal device can enable the network device to determine the first position according to the second power consumption, the second time delay, the terminal capability information (such as support for determining the monitoring position of the first signal according to the configuration information of the first DRX group) or the terminal assistance information (such as expectation of determining the monitoring position of the first signal according to the configuration information of the first DRX group) of the terminal device by sending the third information to the network device, so as to match the position of monitoring the first signal with the above information, and enable the finally determined position of the first signal to be matched with the power consumption demand, the time delay demand, the capability supported by the terminal device or the preference of the terminal device.

[0318] Optionally, the third information is reported through the terminal capability information of the terminal device, and the terminal capability information of the terminal device includes: support for determining the monitoring position of the first signal according to the configuration information of the first DRX group, support for determining the monitoring position of the first signal according to the configuration information of the second DRX group, support for determining the monitoring position of the first signal according to the configuration information of the first DRX group and the second DRX group, support for the second position being one or more positions outside the intersection of the third position and the fourth position or support for the second position being one or more positions outside the union of the third position and the fourth position, and the like.

[0319] Optionally, the third information is reported through terminal assistance information of the terminal device, and the terminal assistance information of the terminal device includes: an expectation of determining the monitoring position of the first signal according to the configuration information of the first DRX group, an expectation of determining the monitoring position of the first signal according to the configuration information of the second DRX group, an expectation of determining the monitoring position of the first signal according to the configuration information of the first DRX group and the second DRX group, an expectation of the second position being one or more positions outside the intersection of the third position and the fourth position or an expectation of the second position being one or more positions outside the union of the third position and the fourth position, and the like.

[0320] Optionally, when the second power of the terminal device is less than the first threshold, the second position is one or more positions outside the intersection of the third position and the fourth position, and when the second delay of the terminal device is less than the second threshold, the second position is one or more positions outside the union of the third position and the fourth position.
