[0041] For the convenience of understanding, some contents related to the embodiments of the present application are described as follows:

[0042] I. Low power wake up receiver (LP WUR).

[0043] The basic working principle of the LP WUR is that the receiving end comprises a first module and a second module. The first module is a main communication module, used to receive and send communication data transmitted by the sending end. The second module is a low-power module, used to receive a low-power wake-up signal (LP-WUS) and a low-power synchronization signal (LP-SS) sent by the sending end. The low-power wake-up signal is used to wake up the main communication module of the receiving end. The low-power synchronization signal is used to provide time reference information and other information for receiving the low-power wake-up signal, for example, for performing radio resource management (RRM) measurement of a serving cell. The low-power synchronization signal can also provide wake-up link management, for example, according to the measurement result to determine whether to activate or deactivate the LP-WUR and turn off the main receiver (MR). When the first module is not woken up by the second module, it is always in a closed state and does not send or receive data. When there is downlink data, the second module detects the low-power wake-up signal sent by the sending end, and the low-power wake-up signal contains terminal information of the terminal, then the second module triggers the first module to switch from the closed state to the working state, and performs data reception and transmission. The second module can be continuously turned on or discontinuously turned on. When the second module is turned on, it can receive the low-power wake-up signal and the low-power synchronization signal.

[0044] II. Low-power wake-up signal

[0045] In this embodiment, the low-power wake-up signal (LP-WUS) does not belong to the downlink control information (DCI), for example, the low-power wake-up signal is not DCI format 2-6 (the DCI format carries wake-up indication information). For example, the waveform or modulation mode of the low-power wake-up signal LP-WUS in this embodiment is: OOK based LP-WUS with overlaid OFDM sequence(s) over OOK symbol. In other words, the low-power signal in this embodiment refers to the LP-WUS with OFDM sequence superimposed on the OOK symbol or chip.

[0046] In order to reduce the receiving activity of the terminal in the standby state, so that the radio frequency (RF) and baseband (MODEM) modules are truly closed to greatly reduce the power consumption of communication reception, the above-mentioned low-power receiver can be introduced in the receiving module of the terminal to achieve this. In one embodiment, this near-zero-power receiver does not require complex signal detection (such as amplification, filtering, quantization, etc.) of the RF module and signal processing of the MODEM, but only relies on passive matching filtering and relatively small power signal processing.

[0047] In one embodiment, the low-power wake-up signal is generally some relatively simple on-off keying (OOK) signal, so that the receiver can identify the wake-up announcement through simple energy detection and subsequent possible sequence detection and other processes. In another embodiment, the low-power wake-up signal can be an FSK signal, an OFDM signal, or a hybrid signal of OFDM and OOK or FSK. In addition, while the terminal turns on the low-power receiver to receive the low-power wake-up signal, the main receiver module can be maintained at a lower power consumption level to achieve power saving through the reception of the low-power wake-up signal.

[0048] The reception of the low-power wake-up signal can be applied to terminals in the RRC idle or RRC inactive state, and can also be applied to terminals in the RRC connected state, so as to achieve terminal energy saving.

[0049] In addition, in addition to the low-power wake-up signal, there is also a low-power synchronization signal or a low-power measurement signal. It can be agreed that the low-power signal is a low-power signal, and the function of the low-power signal is to provide energy saving for the terminal.

[0050] Three, terminal assistance information (UE Assistance Information, UAI) and terminal capability information (UE capability information).

[0051] The UE capability information needs to be triggered by the network side device to report, and the UAI can be reported at any time; the UE capability information is usually reported before the radio resource control (Radio Resource Control) reconfiguration, and the UAI is usually adjusted after the RRC reconfiguration; the UE capability information is static information, and the UAI is dynamic information.

[0052] 1. UE capability information is only sent in response to a request from the base station (gNB), while UAI can be sent when the UE wants to send.

[0053] 2. UE capability information is usually sent before RRC reconfiguration to help the gNB not to configure anything beyond the UE's capabilities, while UEassistanceInformation is sent after RRC reconfiguration to assist the gNB to configure the most suitable parameters for the UE at a specific moment / duration.

[0054] 3. UE capability information usually reports the terminal's maximum or most basic capabilities, while UE assistance information reports the terminal's recommended or preferred configuration at the current moment or time period.

[0055] It should be noted that the main receiver (MR) of the terminal can enter different sleep states by implementing different depths of sleep states, and the transition delay required for the transition from the sleep state to the PDCCH monitoring state will also be different according to the depth. In the LP-WUS monitoring application, the terminal entering different sleep states during the LP-WUS monitoring process is an important factor affecting the delay from receiving the LP-WUS to the terminal MR starting PDCCH monitoring. In one implementation, if the terminal is only allowed to report one value of the above-mentioned delay from LP-WUS to the terminal MR starting PDCCH monitoring through capability information, it cannot provide sufficient information for the network side device to reasonably configure the offset of the LP-WUS monitoring to the start position of the DRX ON duration. Therefore, the information transmission method of the present application is proposed.

[0056] The information transmission method provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and their application scenarios.

[0057] Referring to FIG. 2, the information transmission method provided by the embodiments of the present application includes:

[0058] In step 201, the terminal sends terminal assistance information, wherein the terminal assistance information includes a first time value, the first time value is a recommended value or a preferred value of a target time interval, and the target time interval is a time interval between receiving a low-power wake-up signal and starting PDCCH monitoring.

[0059] In the embodiments of the present application, the above-mentioned first time value can be used to assist the network side device to configure at least one of the following: offset information of the start position of the low-power wake-up signal monitoring relative to the DRX on duration; and offset information between receiving the low-power wake-up signal and starting PDCCH monitoring.

[0060] Optionally, in some embodiments, the terminal assistance information can also include a recommendation type, which is associated with the first time value, and the network-side device can determine the first time value reported by the terminal according to the recommendation type reported by the terminal.

[0061] Optionally, in some embodiments, the first time value can be associated with at least one of a service requirement and a sleep state of the terminal, wherein the terminal has different energy consumptions in different sleep states, and the sleep state can be understood or replaced as an energy-saving state. In other words, in some embodiments, the terminal can determine the first time value according to at least one of the service requirement and the sleep state that the terminal needs to enter.

[0062] In the embodiments of the present application, the terminal sends terminal assistance information, the terminal assistance information includes a first time value, the first time value is a recommended value or a preferred value or a preferred value of a target time interval, and the target time interval is a time interval between receiving a low-power wake-up signal and starting physical downlink control channel (PDCCH) monitoring by the terminal. In this way, since the recommended value of the target time interval is reported through the terminal assistance information, the network-side device can understand the energy-saving requirement of the terminal, and accordingly configure a more appropriate offset information of the low-power wake-up signal monitoring relative to the starting position of the DRX onduration. Therefore, the embodiments of the present application improve the flexibility and adaptability of the offset information configuration, thereby helping the terminal to improve the energy-saving effect.

[0063] Optionally, in some embodiments, the method further includes:

[0064] The terminal sends capability information, the capability information includes at least one capability type or at least one second time value, wherein the capability type is associated with the second time value, and the second time value is a value of the target time interval supported by the terminal.

[0065] Optionally, the terminal sends the capability information and the terminal assistance information without distinguishing the order. In one embodiment, generally, the terminal sends the terminal capability information before sending the terminal assistance information. In another embodiment, the terminal is triggered to send the terminal capability information after sending the terminal assistance information.

[0066] In the embodiments of the present application, the second time value can be understood or replaced as a value of the smallest target time interval supported by the terminal.

[0067] In an embodiment, in the case that the capability information includes at least two capability types or at least two second time values, the different capability types or different second time values are associated with at least one of the following: service requirement and sleep state of the terminal. For example, in some embodiments, the multiple second time values satisfy at least one of the following: different second time values correspond to different service requirements, or different second time values correspond to different sleep states. Meanwhile, the multiple capability types satisfy at least one of the following: different capability types correspond to different service requirements, or different capability types correspond to different sleep states. The sleep state refers to the power saving state of the terminal.

[0068] Optionally, the different capability types can be associated with different second time values, the terminal can implicitly indicate the second time value through the capability type, or the terminal can directly display the indication of the second time value, i.e., the second time value is included in the capability information.

[0069] In an embodiment, the terminal reports multiple second time values through the capability. In addition, the terminal also reports a first time value through the terminal assistance information. Further, the first time value is a second time value currently recommended or preferred by the terminal from the multiple second time values. Therefore, the network side can understand the target time interval with the terminal through the terminal capability report and the terminal assistance information report, and configure reasonable offset information.

[0070] It should be understood that, in the embodiments of the present application, at least one capability type or at least one second time value is reported through the capability information, to further assist the network side device in configuring the offset information of the low-power wake-up signal monitoring relative to the start position of the discontinuous reception duration (DRX on duration). Therefore, the accuracy of the offset information configuration is improved.

[0071] Optionally, in some embodiments, the method further includes any of the following:

[0072] The terminal determines the at least one second time value from candidate values of the target time interval, which are configured by the network side device or agreed by the protocol;

[0073] The terminal determines the at least one capability type from candidate capability types of the target time interval, which are configured by the network side device or agreed by the protocol.

[0074] In the embodiments of the present application, the terminal can receive at least one of the candidate values of the target time interval and the candidate capability types of the target time interval from the network side device, and then report the capability information.

[0075] For example, the protocol agrees that the terminal reports the supported capability type through capability report about the candidate type of the minimum target time interval.

[0076] In the above table, the minimum target time interval candidate capability type and the corresponding value (Minimum time gap value X) of each capability type are shown as follows:

[0077] In the above table, the minimum target time interval candidate capability type and the corresponding value (Minimum time gap value X) of each capability type are shown as follows:

[0078] Optionally, in some embodiments, the terminal determines at least one second time value or at least one capability type according to at least one of the service requirement and the sleep state that the terminal needs to enter.

[0079] Optionally, in some embodiments, the first time value and the second time value can be different, or the at least one second time value contains the first time value.

[0080] Further, in the case where the terminal only reports one second time value, the first time value reported by the terminal through the assistance information can be different from the second time value.

[0081] Further, in the case where the terminal reports multiple second time values, the first time value reported by the terminal through the assistance information can be selected from the multiple second time values as the first time value, that is, the at least one second time value contains the first time value.

[0082] In the embodiments of the present application, the above-mentioned first time value can be one or more, wherein the second time value reported through the capability can be the same as or different from the first time value reported through the assistance information.

[0083] Optionally, the same can be understood as the first time value reported by the terminal through the terminal assistance information being one of the multiple second time values reported by the terminal through the capability information.

[0084] For example, in some embodiments, the three second time values reported through the capability are time 1, time 2 and time 3, and the first time value reported through the terminal assistance information can be time 1, time 2 or time 3, or a new time 4 can be reported.

[0085] Optionally, in some embodiments, when the capability information comprises a second time value, the second time value is a maximum or minimum value of the target time interval supported by the terminal. It can be understood that in this case, the terminal can support multiple values of the target time interval.

[0086] In the embodiments of the present application, it is assumed that the values of the target time interval supported by the terminal include time 1, time 2 and time 3, and time 1 is greater than time 2, and time 2 is greater than time 3. In this case, if a second time value is reported through the capability information, the reported second time value can be time 1 or time 3. Since only the maximum or minimum value of at least two of the target time intervals supported by the terminal is reported, the resource overhead of the report can be reduced.

[0087] Optionally, in some embodiments, the capability information comprises at least one capability type or at least one second time value associated with different discontinuous reception (DRX) groups or cell groups.

[0088] In the embodiments of the present application, one or more second time values can be included for each DRX group or cell group. When sending the capability information, the second time value corresponding to each DRX group or cell group in one or more DRX groups or cell groups can be reported. For example, the network configures two DRX groups (group) for the terminal, and the terminal reports the associated capability information for DRX group 1 when reporting the capability information, and reports the associated capability information for DRX group 2. Correspondingly, the terminal reports the corresponding first time value for the two DRX groups through the terminal assistance information, that is, respectively recommends the target time interval. In addition, the same is true for multiple cell groups (cell group), which will not be described here.

[0089] Optionally, in some embodiments, the start position of the target time interval is the end position of a target time unit or the start position of a next time unit of the target time unit, wherein the target time unit is the last time unit in the time unit in which the terminal receives the low-power wake-up signal.

[0090] In the embodiments of the present application, the granularity of the target time unit can be millisecond, frame, subframe, time slot or sub-time slot, which will not be further limited here. Since the definition of the start position of the target time interval is clear, the terminal and the network side device can have a consistent understanding of the target time interval.

[0091] Optionally, in some embodiments, the first time value or the second time value is associated with a subcarrier spacing.

[0092] In the embodiments of the present application, the terminal can further indicate the subcarrier spacing associated with the first time value or the second time value when reporting the terminal capability information or the assistance information, so as to improve the accuracy of the network side device in understanding the first time value and the second time value reported by the terminal.

[0093] Optionally, in some embodiments, the triggering manner of the terminal assistance information reporting comprises at least one of the following:

[0094] Event triggering;

[0095] Periodic triggering.

[0096] Optionally, in the case of event-based triggering of the terminal assistance information reporting, the event can be configured by the network side device or agreed by a protocol, and the terminal sends the terminal assistance information when the terminal meets the event. The content of the event can be set according to actual needs, and is not limited herein. For example, in some embodiments, the event can be that the quality of the serving cell of the terminal is lower than a certain threshold, or the terminal is in a specific motion state, etc.

[0097] Optionally, in the case of periodic triggering, the network side device can configure the period of sending the terminal assistance information, and the terminal sends the terminal assistance information periodically based on the configured period.

[0098] Optionally, in some embodiments, the method further comprises:

[0099] In the case that the terminal sends the terminal assistance information, the terminal starts a target timer;

[0100] During the running of the target timer, the terminal prohibits sending the terminal assistance information.

[0101] In the embodiments of the present application, the terminal starts a target timer, which can be a prohibit timer. Since the target timer is set, the terminal is prohibited from sending the terminal assistance information during the running of the target timer, so that the frequency of sending the terminal assistance information can be reduced, thereby reducing the signaling overhead.

[0102] Optionally, in some embodiments, the method further comprises:

[0103] The terminal receives target offset information, and the target offset information comprises at least one of the following: offset information of the low-power wake-up signal listening relative to the starting position of the discontinuous reception duration (DRX onduration); offset information between receiving the low-power wake-up signal and starting PDCCH listening.

[0104] In the embodiments of the present application, the network side device can determine the target offset information based on at least one of the terminal assistance information and the capability information. Of course, in some embodiments, before the terminal reports the terminal assistance information and the capability information, the network side device can also configure the target offset information based on a predefined rule, for example, according to the default offset information.

[0105] Optionally, in some embodiments, the target offset information is carried by at least one of radio resource control (RRC) signaling, a medium access control (MAC) element, and downlink control information (DCI).

[0106] Optionally, in some embodiments, at least one of the target time interval and the target offset has a unit of millisecond or time slot.

[0107] Optionally, in some embodiments, the terminal does not need to perform transmission or reception in the target time interval corresponding to the first time value or the second time value. Optionally, the "does not need" can be replaced by "does not expect".

[0108] In the embodiments of the present application, the reception that does not need to be performed includes at least one of the following: PDCCH reception does not need to be performed; low-power wake-up signal reception does not need to be performed.

[0109] Optionally, in some embodiments, the terminal assistance information includes the first time value associated with different DRX groups or cell groups respectively.

[0110] In the embodiments of the present application, one first time value can be included for each DRX group or cell group. When reporting the terminal assistance information, the first time value corresponding to each DRX group or cell group in one or more DRX groups or cell groups can be reported.

[0111] Optionally, the terminal assistance information can be reported per cell group (per cell group). For example, in a DC scenario, different first time values can be configured for a master cell group (MCG) and a secondary cell group (SCG). Alternatively, the terminal assistance information can be reported per DRX group (per DRX group), for example, in the case where dual DRX groups are configured.

[0112] In order to better understand the present application, some examples are described in detail below.

[0113] In some embodiments, the terminal reports a second time value through the capability information, and reports the recommended first time value through the terminal assistance information.

[0114] The main radio (MR) of the terminal can enter different sleep states (deep sleep, light sleep, micro sleep) to save the power consumption of the terminal. When the terminal enters the sleep state, the terminal cannot perform PDCCH monitoring or data transmission. In addition, the terminal enters different sleep states to save power by turning off or partially turning off the relevant power consumption modules. It can be understood that when the terminal enters different sleep states, the conversion time interval required to recover from the sleep state to the PDCCH monitoring state is different.

[0115] For example, when the terminal enters a deep sleep state, the terminal can turn off most of the power consumption modules to achieve a large degree of energy saving. Therefore, the conversion time interval required for the terminal to convert from the deep sleep state to the PDCCH monitoring state is long, for example, a conversion delay of 10 ms. When the terminal enters a light sleep state, the corresponding conversion delay will be shorter, for example, 3 ms. When the terminal enters a micro sleep state, the power consumption module is turned off the least, and the corresponding conversion delay will be shorter, for example, 0 ms.

[0116] In addition, the target time interval is related to at least one of the following:

[0117] The processing delay of the LP-WUS;

[0118] The conversion delay of the terminal from different sleep states to the PDCCH monitoring state;

[0119] The synchronization delay in the time-frequency domain.

[0120] For example, the terminal 1 can correspond to multiple values of the target time interval, for example, 15 ms, 8 ms, and 2 ms, because the terminal 1 can enter different sleep states or energy saving states (deep sleep, light sleep, and micro sleep).

[0121] In one embodiment, the terminal reports a second time value via capability information. In addition, the terminal reports a first time value via UAI. For example, the terminal 1 reports a second time value of 2 ms via capability information. In addition, the terminal reports a first time value of 15 ms via UAI. The network device can learn from the capability information that the minimum target time interval supported by the terminal is 2 ms, and learn from the UAI information that the additional target time interval currently recommended by the terminal for power saving is 15 ms. Then, the network device can use the information to reasonably configure the offset of the LP-WUS monitoring relative to the start position of the DRX ON duration or the PDCCH monitoring for the terminal. Alternatively, the offset is not less than the minimum target time interval supported by the terminal reported via the capability information. For example, the network device configures the offset to be 20 ms. Then, the MR of the terminal 1 can enter a deep sleep state during the LP-WUS monitoring, thereby achieving more power saving.

[0122] In some embodiments, the terminal reports multiple second time values via capability information, and reports a recommended second time value (i.e., a first time value) via terminal assistance information.

[0123] For example, the terminal 1 reports three second time values {15 ms, 8 ms, 2 ms} via capability information. The terminal 1 recommends a first time value currently preferred by the UE via UAI. Alternatively, the first time value preferred by the terminal reported via the UAI can be the same as or different from the second time value reported via the capability information. For example, the UE 1 reports a recommended first time value of 10 ms via UAI. The network device can configure the offset of the LP-WUS monitoring relative to the start position of the DRX ON duration for the terminal according to the UAI preference currently reported by the terminal.

[0124] Further, if the terminal has no UAI reporting preference, the network configures the application according to a default target time interval. The default target time interval can be specified by the terminal via capability, or determined by protocol agreement, etc.

[0125] It should be noted that the embodiments of the present application report a LP-WUS to terminal MR start PDCCH monitoring delay (such as the minimum value in the above-mentioned multiple time delays) via capability information, and recommend another time delay value (such as a time delay value that can bring the terminal maximum power saving) via UAI terminal assistance information, to provide more information for the network device, and facilitate the network device to configure a more reasonable offset of the LP-WUS monitoring relative to the start position of the DRX ON duration for the terminal.

[0126] In some embodiments, the terminal reports the recommended first time value through terminal assistance information.

[0127] For example, the terminal reports the UAI, giving the first time value recommended by the terminal.

[0128] Optionally, the recommended first time value given by the terminal can be selected from a specific set of candidate values as the currently recommended first time interval value. For example, the protocol agrees that the candidate value set of the first time interval is {1, 2, 3, 4, 5, 6, 7, 8, 9, 10…20}, and the unit of these values can be ms or slot. If it is slot, it is necessary to select the corresponding value according to the subcarrier spacing (SCS) corresponding to the LP-WUS of the terminal.

[0129] The network side device can configure the terminal with the offset of LP-WUS monitoring relative to the starting position of DRX ONduration and / or the offset of LP-WUS monitoring relative to PDCCH monitoring according to the UAI preference currently reported by the terminal.

[0130] Optionally, the UAI can also be reported per cell group, such as MCG, SCG for DC scenario. Or the UAI information can be reported per DRX group, if dual DRX groups are configured.

[0131] For example, if the terminal is configured with dual connection (DC), the terminal reports the preferred first time value for MCG and the preferred first time value for SCG through the UAI information report.

[0132] For another example, if the terminal is configured with carrier aggregation (CA), the terminal reports the preferred first time interval for the primary DRX group and the preferred first time interval for the secondary DRX group through the UAI information report.

The network side device embodiment corresponds to the network side device method embodiment described above, and each implementation process and implementation manner of the method embodiment described above can be applied to the network side device embodiment and achieve the same technical effects.

[0200] Specifically, the embodiment of the application further provides a network side device, which can be the information transmission apparatus shown in FIG. 5. As shown in FIG. 8, the network side device 800 comprises an antenna 801, a radio frequency device 802, a baseband device 803, a processor 804 and a memory 805.

[0205] From the above embodiments, it can be seen that the communication system can further save power consumption by introducing the low-power wake-up signal LP-WUS, and the network side device can send the LP-WUS to the terminal when the main receiver of the terminal needs to be woken up, but in the prior art, the network side device sends the LP-WUS by using the same low-power wake-up signal occasion (LP-WUS occasion, LO) offset for all terminals, but there are different types of terminals in the system, some terminals support a longer wake-up delay, and some terminals support a shorter wake-up delay, if the same offset is used, it will cause some terminals to wake up for a long time or some terminals cannot be woken up in time. To solve this problem, the embodiment of the present application provides the following information transmission method.

[0206] The embodiment of the present application provides an information transmission method, comprising:

[0207] The terminal listens to the low-power wake-up signal at at least one low-power wake-up signal occasion LO according to the configuration information of the low-power wake-up signal.

[0208] The configuration information at least comprises at least two offsets, each offset corresponding to one LO, and the offset is the time interval between the LO and the reference paging occasion (PO) or the reference paging frame (PF) associated with the LO. Optionally, the terminal can receive the configuration information through broadcast signaling, and further, the network side device can configure one LO to be associated with one PO or a group of POs. Optionally, the group of POs can refer to all POs associated with one PF or multiple PFs. In one embodiment, the first PO or the first PF in the group of POs or the group of PFs associated with one LO is taken as the reference PO or the reference PF.

[0209] In this way, the terminal in the embodiment of the present application receives the configuration information of the LP-WUS sent by the network side device, and the configuration information carries at least two offsets, so that the terminal can determine which offset to use to listen to the LP-WUS according to the capability supported by itself, thereby avoiding the problem of increased power consumption caused by the inability to wake up or premature wake-up caused by inappropriate offsets.

[0210] Optionally, the at least two offsets include the first offset and the second offset, a value of the first offset is greater than a value of the second offset, for example, the first offset has an offset value of 800 ms, and the second offset has an offset value of 40 ms.

[0211] Optionally, the terminal listens to the low-power wake-up signal on the at least one LO according to the configuration information of the low-power wake-up signal and the wake-up latency supported by the terminal, including: the terminal listens to the low-power wake-up signal on the at least one LO according to the configuration information of the low-power wake-up signal and the wake-up latency supported by the terminal. For example, the terminal listens to the low-power wake-up signal on at least one low-power wake-up signal occasion LO in a paging cycle according to the configuration information of the low-power wake-up signal. In an embodiment, the terminal listens to the low-power wake-up signal on at least two low-power wake-up signal occasions LO according to the configuration information of the low-power wake-up signal, and the at least two LOs correspond to the at least two offsets.

[0212] Optionally, the terminal listens to the low-power wake-up signal on the at least one LO according to the configuration information of the low-power wake-up signal and the wake-up latency supported by the terminal, including any of the following:

[0213] In the case that the terminal supports the first wake-up latency, the terminal listens to the low-power wake-up signal on the LO corresponding to the first offset according to the configuration information of the low-power wake-up signal. For example, for a terminal supporting the first wake-up latency, the terminal only listens to the low-power wake-up signal on one LO (i.e., LO1) corresponding to the first offset.

[0214] In the case that the terminal supports the second wake-up latency, the terminal listens to the low-power wake-up signal on the LO corresponding to the first offset and the LO corresponding to the second offset according to the configuration information of the low-power wake-up signal. For example, for a terminal supporting the second wake-up latency, the terminal needs to listen to the low-power wake-up signal on two LOs (e.g., LO1 and LO2 as shown in FIG. 9) corresponding to the two low-power wake-up signal offsets, so that the terminal can detect the low-power wake-up signal sent by the network side device on any LO, without increasing the implementation complexity of the network side, while ensuring that the terminal wakes up normally. In addition, since the terminal listens on both LOs, the network side also has flexibility in sending the wake-up signal to the terminal. For the second wake-up latency terminal, the sending method of the low-power wake-up signal by the network side does not increase the power consumption of the terminal.

[0215] Optionally, the first wake-up latency is greater than the value of the second wake-up latency. In an embodiment, the first wake-up latency can only be selected from a first candidate value set, and the second wake-up latency can only be selected from a second candidate value set.

[0216] It should be noted that the values in the two candidate value sets do not intersect. The network side configures or protocol agrees the candidate value set. For example, the network side device configures the terminal to report the candidate value set of the wake-up delay.

[0217] In an embodiment, the terminal wake-up delay type can include: a wake-up delay corresponding to the terminal entering a super deep sleep state from receiving a wake-up signal to being able to listen to a PDCCH (such as a first wake-up delay), and a wake-up delay corresponding to the terminal entering a deep sleep state from receiving a wake-up signal to being able to listen to a PDCCH (such as a second wake-up delay). When the terminal enters different sleep states, the wake-up delay required for the terminal to transition from the different sleep states to the PDCCH listening state is different.

[0218] Further, in the case that the terminal supports the first wake-up delay, the terminal listens to the low-power wake-up signal on the LO corresponding to the first offset according to the configuration information of the low-power wake-up signal, comprising: in the case that the terminal supports the first wake-up delay, if there are multiple values of the first offset in the at least two offsets, the terminal listens to the low-power wake-up signal on the LO corresponding to one of the multiple values of the first offset.

[0219] Optionally, the method further comprises: if the terminal listens to the low-power wake-up signal on at least one LO according to the configuration information of the low-power wake-up signal, the terminal determines whether to listen to the PO of the terminal associated with the at least one LO according to the indication of the listened low-power wake-up signal.
