Description

Low-power wake-up signal monitoring method and device

[0001] The present application claims priority to the Chinese patent application No. 202411126322.0, filed on August 15, 2024, and entitled "Low-power wake-up signal monitoring method and device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and in particular to a low-power wake-up signal monitoring method and device. BACKGROUND

[0003] To reduce the energy consumption of a terminal device, a discontinuous reception (DRX) mechanism is proposed. In an active period of a DRX cycle, the terminal device monitors a physical downlink control channel (PDCCH); in a sleep period of the DRX cycle, the terminal does not monitor the PDCCH, thereby reducing the energy consumption of the terminal device.

[0004] However, when there is emergency service in the sleep period of the DRX cycle, the network device sends an emergency data packet to the terminal device. At this time, since the terminal device does not monitor the PDCCH, the emergency data packet from the network device cannot be received, which causes a data missing problem. SUMMARY

[0005] The embodiments of the present application provide a low-power wake-up signal monitoring method and device, which is beneficial to reducing the probability of missing data of a terminal device in a sleep period of a DRX cycle while reducing the power consumption of the terminal device.

[0006] In a first aspect, the embodiments of the present application provide a low-power wake-up signal monitoring method, which can be executed by a terminal device. The terminal device can also be a processor, a module, a chip, or a chip system or a software module, etc. that can implement the method. In the method, the terminal device monitors a low-power wake-up signal (LP-WUS) in a first time period based on a first monitoring mode. The first monitoring mode is used to indicate that the LP-WUS is monitored in at least one first monitoring occasion (MO), or is used to indicate that the LP-WUS is not monitored in at least one second MO. The first time period includes part or all of a sleep period of a discontinuous reception (DRX) cycle.

[0007] It can be seen that, by the above method, the terminal-side device can monitor the LP-WUS in part or all of the sleep period of the DRX cycle based on the first monitoring mode, thereby facilitating the terminal-side device to listen to the PDCCH based on the monitored LP-WUS, and reducing the probability of missing data of the terminal-side device in the sleep period of the DRX cycle while reducing the power consumption of the terminal-side device.

[0008] In an optional implementation, the first time period further includes at least one of the following: part or all of the active period of the DRX cycle, part or all of the active period of a monitoring cycle. The monitoring cycle is a cycle composed of a time period of monitoring the LP-WUS MO and a time period of not monitoring the LP-WUS MO. In addition, the monitoring cycle and one cycle time of the DRX cycle can be the same or different. The time period of monitoring the LP-WUS MO is the active period of the monitoring cycle.

[0009] The mode that the first time period further includes part or all of the active period of the DRX cycle facilitates the terminal-side device to monitor the LP-WUS in part or all of the active period of the DRX cycle based on the first monitoring mode in the case that a timer used for timing the listening to the PDCCH expires or is closed in advance in the active period of the DRX cycle, thereby reducing the probability of missing data of the terminal-side device.

[0010] In another optional implementation, the first time period further includes an active period of a transmission cycle. The transmission cycle is a cycle associated with a low-power LR module of the terminal-side device, or in other words, the transmission cycle is a cycle pre-configured by the network-side device for the LR module of the terminal-side device, or in other words, in the active period of the transmission cycle, the terminal-side device receives signals using the LR module; in the sleep period of the transmission cycle, the terminal-side device does not receive signals using the LR module. In addition, the active period of the transmission cycle includes at least one of the following: part or all of the sleep period of the DRX cycle, part of the active period of the DRX cycle.

[0011] When the active period of the transmission cycle includes part or all of the sleep period of the DRX cycle, the first time period includes part or all of the sleep period of the DRX cycle, thereby enabling the terminal-side device to monitor the LP-WUS in part of the sleep period of the DRX cycle, and further enabling the terminal-side device to listen to the PDCCH based on the monitored LP-WUS, thereby reducing the probability of missing data. When the active period of the transmission cycle includes part of the active period of the DRX cycle, the first time period includes part of the active period of the DRX cycle, which facilitates the terminal-side device to monitor the LP-WUS in part of the active period of the DRX cycle in the case that a timer used for timing the listening to the PDCCH expires or is closed in advance in the active period of the DRX cycle, thereby reducing the probability of missing data of the terminal-side device.

[0012] In an optional implementation, the LP-WUS monitored by the terminal-side device is used to indicate at least one of the following: monitoring or not monitoring a physical downlink control channel (PDCCH) in a second time period, a range of monitoring the PDCCH in the second time period, and a range of not monitoring the PDCCH in the second time period. The second time period is part of or the entire first time period. In this way, the terminal-side device can monitor the PDCCH based on the monitored LP-WUS during part of or the entire sleep period of the DRX cycle, and the probability of missing data during part of or the entire sleep period of the DRX cycle can be reduced.

[0013] In an optional implementation, the terminal-side device further receives first configuration information. The first configuration information is used to configure the first monitoring mode, or is used to configure a plurality of monitoring modes including the first monitoring mode.

[0014] In a possible implementation, the first configuration information is carried in a non-low-power signal in an active period of the DRX cycle. This implementation can save signaling overhead compared to sending the first configuration information through other additional signals / signaling.

[0015] In another possible implementation, the first configuration information is carried in a low-power signal in a sleep period or an active period of the DRX cycle. This implementation can save energy consumption.

[0016] In yet another possible implementation, the first configuration information is carried in a low-power signal in an active period of a monitoring period. This implementation can save energy consumption.

[0017] In yet another possible implementation, the first configuration information is carried in a low-power signal in an active period of a transmission period. This implementation can save energy consumption.

[0018] In an optional implementation, the terminal-side device further receives first indication information. The first indication information is used to indicate activating the first monitoring mode.

[0019] In a possible implementation, the first indication information is specifically used to indicate activating the first monitoring mode in one or more first time periods, or the first indication information is specifically used to indicate activating the first monitoring mode in part or all of a first time period.

[0023] In an optional implementation, the first indication information is carried in a non-low-power signal in the active period of the DRX period, or the first indication information is carried in a low-power signal in the sleep period or the active period of the DRX period. This mode enables the network-side device to activate the first monitoring mode of the terminal-side device without additional signal / signaling indication, thereby reducing signaling overhead.

[0024] In another optional implementation, the first indication information is carried in a low-power signal in the active period of the monitoring period. In another optional implementation, the first indication information is carried in a low-power signal in the active period of the transmission period.

[0045] In a possible manner, after receiving the third indication information, the terminal-side device can further perform the following steps: switching the first monitoring mode to the second monitoring mode based on the third indication information. In another possible manner, after receiving the third indication information, the terminal-side device can further perform the following steps: deactivating the first monitoring mode and activating the second monitoring mode based on the third indication information. It can be seen that, after receiving the third indication information, the terminal-side device no longer uses the first monitoring mode to monitor the LP-WUS in the first time period, and subsequently uses the second monitoring mode to monitor the LP-WUS.

[0046] In an optional implementation, the second indication information or the third indication information is carried in a low-power signal, such as a low-power signal in a sleep period or an active period of a DRX cycle, such as a low-power signal in an active period of a monitoring cycle, or such as a low-power signal in an active period of a transmission cycle.

It can be seen that the terminal-side device can monitor the LP-WUS in the timing period of the first timer in part or all of the active period of the DRX cycle, so as to listen to the PDCCH based on the monitored LP-WUS. Compared with the terminal-side device continuously listening to the PDCCH in the active period of the DRX cycle, this manner can reduce the number of times of listening to the PDCCH, thereby reducing the power consumption of the terminal-side device.

[0138] In the embodiments of the present application, the network device is a device with wireless transceiving function, used for communicating with the terminal device, which can be an evolved Node B (eNB or eNodeB) in LTE, or a base station in a 5G / 6G network, or a base station in a future evolved public land mobile network (PLMN), a broadband network gateway (BNG), a convergence switch, or a non-3rd generation partnership project (3GPP) access device, etc. Optionally, the network device in the embodiments of the present application can include various forms of base stations, such as: a macro base station, a micro base station (also known as a small station), a relay station, an access point, a device realizing a base station function in the future, an access point (AP) in a wireless fidelity (WiFi) system, a transmission reception point (TRP), a transmission point (TP), a mobile switching center, and a device assuming a base station function in D2D, V2X, machine-to-machine (M2M) communication, a device realizing a base station function in a communication system evolved after 5G, integrated access and backhaul (IAB), and can also include a centralized unit (CU) and a distributed unit (DU) in a cloud radio access network (C-RAN) system, a network device in a non-terrestrial network (NTN) communication system, i.e., can be deployed on a high-altitude platform or a satellite, and can also be various devices constituting an access node, such as an active antenna processing unit (AAU), a baseband unit (BBU), etc., which are not limited in the embodiments of the present application.

[0139] The network device can communicate with a core network device, and provide a communication service to the terminal device. The core network device is, for example, a device in a 5G network core network (CN). The core network serves as an interface to a data network, provides communication connection, authentication, management, policy control, and data service bearing for the terminal.

[0141] The embodiments of the present application can be applied to a standalone (SA) communication scenario. The SA communication scenario refers to that a terminal device is connected with a single base station, and the base station connected by the terminal device and the core network connected by the base station are of the same standard. For example, FIG. 2 is a schematic diagram of a system architecture of standalone networking. As shown in FIG. 2, the core network is 6G core, the base station connected by the terminal device is a 6G base station, and the 6G base station is directly connected with the 6G core. For another example, the core network is 5G core, the base station connected by the terminal device is a 5G base station, and the 5G base station is directly connected with the 5G core.

For another example, the core network is 6G core, the terminal device is simultaneously connected with two 6G base stations, i.e., the primary station and the secondary station are both 6G base stations.

[0143] The embodiments of the present application can also be applied to a scenario where a wide coverage base station and a small coverage base station exist simultaneously, such as a macro-micro scenario in a current network. For example, FIG. 4 is a schematic diagram of a system architecture of a macro-micro scenario. Specifically, FIG. 4 is a schematic diagram of a system architecture of a macro-micro scenario where a wide coverage base station and a small coverage base station exist simultaneously.

[0144] The embodiments of the present application can also be applied to a macro-micro scenario composed of different forms of base stations in a future network. For example, FIG. 5 is another schematic diagram of a system architecture of a macro-micro scenario. As shown in FIG. 5, a super station can be connected with multiple ground sites. The super station in FIG. 5 can be a satellite, an air balloon station, a drone site, and the like, and the ground site can be a current cellular site (macro station, small station, micro station, and the like).

[0145] Embodiments disclosed herein will present various aspects, embodiments, or features of the present application in the context of systems that include a plurality of devices, components, modules, etc. It should be understood and appreciated that each system can include additional devices, components, modules, etc., and / or can not include all of the devices, components, modules, etc., discussed in connection with the figures. Additionally, a combination of these approaches can also be used.

[0146] In order to facilitate the understanding of the solutions of the embodiments of the present application, the following explains the terms that the embodiments of the present application can involve.

[0147] 1. Wake up signal (WUS), low power-wake up signal (LP-WUS).

[0148] The WUS is used to make the device recover from the standby / sleep state to the working state. The LP-WUS is a kind of WUS proposed to reduce the power consumption of the device.

[0149] The LP-WUS in the embodiments of the present application can be used to indicate at least one of the following: whether to monitor the physical downlink control channel (PDCCH), the range of monitoring the PDCCH, and the range of not monitoring the PDCCH. The range of monitoring or not monitoring the PDCCH may, for example, be a time domain range, a frequency domain range, a number of candidates, etc. For example, the LP-WUS is used to indicate whether to monitor / not monitor the PDCCH in a certain time period.

[0150] 2. Main radio (MR) module, low-power radio (LR or LP-R) module.

[0151] The MR module can also be referred to as a main radio, a main receiver, a main communication module, or a main circuit, etc. The MR module can be used to receive or send signaling, data, measurement signals, etc. The MR module can be in an off state when the LR module is in an active state and searches for a potential WUS signal, thereby achieving energy saving.

[0152] The LR module can also be referred to as a low-power radio, a wake-up receiver (WUR), a low-power WUR (LP-WUR), a wake-up circuit, an auxiliary communication module, or an auxiliary circuit, etc. The working power consumption of the LR module is much lower than that of the MR module. The LR module is used to receive or send low-power signals (such as low-power wake-up signals, low-power synchronization signals, low-power measurement signals, etc.), notify the wake-up / sleep / monitoring information of the MR, etc.

[0153] In the embodiments of the present application, the terminal device and the network device include an MR module and an LR module. The structure of the terminal device and the network device is shown in FIG. 6. The terminal device and the network device can transmit signaling, data, measurement signals, etc. through the MR module. The terminal device and the network device can also transmit low-power consumption signals through the MR module. The network device and the terminal device can also transmit low-power consumption signals through the LR module. The LR module can not only undertake the reception of some signals for the MR module, but also can exchange information with the MR, thereby controlling the activation / sleep of the MR.

[0154] For example, FIG. 7 is a schematic diagram of a LP-WUS wake-up master module. As shown in FIG. 7, when the LP-WUS signal transmitted by the network device to the terminal device does not contain the wake-up message of the terminal device (corresponding to OFF in FIG. 7), the terminal device does not need to wake up the MR module, i.e., the MR module is still in the sleep state. When the LP-WUS signal transmitted by the network device to the terminal device contains the wake-up message of the terminal device (corresponding to ON in FIG. 7), the LR module of the terminal device will send a trigger signal for waking up the master receiver.

[0155] 3. Low-power consumption signal.

[0156] In the embodiments of the present application, the low-power consumption signal can be one or more of a linear frequency modulation chirp signal, an on-off keying (OOK) signal (such as OOK-1, OOK-2, OOK-3, OOK-4, etc.), a low-power consumption sequence signal (such as a Gold sequence signal, a Weil exponential and sequence, an M sequence signal, a ZC sequence signal, a Chirp sequence signal, a Walsh sequence signal, a Golay sequence signal, a Kasami sequence signal, a low density sequence signal, a discrete fourier transform (DFT) / fast fourier transform (FFT) sequence signal, a quadrature amplitude modulation (QAM) signal, a symbol-based sequence signal, etc.), an amplitude shift keying (ASK) signal, a frequency shift keying (FSK) signal, an orthogonal frequency division multiplexing (OFDM) signal, etc. Alternatively, the low-power consumption signal can also be a signal obtained by optimizing the above signals, etc., which is not limited in the present application.

[0157] 4. discontinuous reception (DRX).

[0158] In actual service, the terminal is not always in interaction with the network for effective information, and will not always perform uploading or downloading service, and there is no transmission of voice data during a call. Most of the time, the terminal and the network have no data interaction, and if the terminal continues to monitor the PDCCH at this time, it will cause waste of terminal power. Therefore, under the premise of ensuring effective transmission of data, a mechanism for saving terminal power is designed, which is called DRX.

[0159] When the network has service data to send to the terminal, the terminal monitors the PDCCH channel; otherwise, the terminal turns off the receiver and no longer continuously monitors the PDCCH channel to save the power consumption of the terminal and prolong the standby time of the terminal. FIG. 8 is a schematic diagram of a DRX cycle provided by an embodiment of the present application. In FIG. 8, the time period marked as "on duration" is the time period in which the terminal monitors the PDCCH, and in this time period, the terminal is in a wake-up state, which belongs to an "active period". In FIG. 8, the time period of the DRX cycle that is not in the ON duration is the DRX sleep time, that is, the time in which the terminal enters sleep to save power and does not monitor the PDCCH, which belongs to a "sleep period".

[0160] The network device can control the DRX operation by configuring any one or more of the following parameters through a radio resource control (RRC) message:

[0161] DRX on duration timer (drx-onDurationTimer): a time period at the beginning of the DRX cycle. The position where the drx-onDurationTimer starts or restarts can be calculated according to the parameters configured by the base station and the formula specified by the protocol.

[0162] DRX inactivity timer (drx-InactivityTimer): indicates a time period after a PDCCH occasion for new transmission of uplink or downlink. For example, the terminal device receives a PDCCH (for example, a PDCCH scrambled by a C-RNTI or a CS-RNTI), which indicates a new uplink or downlink transmission (i.e., a new transmission scheduling), and starts or restarts the drx-InactivityTimer.

[0163] DRX retransmission timer (drx-RetransmissionTimerDL) for downlink: the maximum duration until a downlink (DL) retransmission is received. For example, drx-HARQ-RTT-TimerUL expires and the data is not successfully decoded, the drx-RetransmissionTimerDL is started or restarted.

[0164] DRX retransmission timer (drx-RetransmissionTimerUL) for uplink: the maximum duration until a grant for an uplink (UL) retransmission is received. For example, drx-HARQ-RTT-TimerUL expires, the drx-RetransmissionTimerUL is started or restarted in the first symbol after the expiry of drx-HARQ-RTT-TimerUL for the corresponding HARQ process.

[0165] Contention resolution timer: is a timer related to preamble contention resolution, indicating the valid duration for the terminal device to wait for receiving Msg4 after sending Msg3 in the random access process. If the contention resolution timer expires, the random access fails, and the terminal device returns to the process of sending Msg1 and performs re-access.

[0166] The embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments of the present application take the terminal side device and the network side device as the execution subject to illustrate the corresponding method. For example, the terminal side device is the terminal device in the system shown in FIG. 1, and the network side device is the network device in the system shown in FIG. 1. However, the present application does not limit the execution subject of the method. For example, the terminal side device in the method can also be a processor, a module, a chip, or a chip system or a software module supporting the implementation of the corresponding method.

[0167] The embodiment of the present application proposes a low-power wake-up signal monitoring method. FIG. 9 is a flowchart of the low-power wake-up signal monitoring method. The low-power wake-up signal monitoring method is described from the perspective of the terminal side device. The low-power wake-up signal monitoring method includes but is not limited to the following steps:

[0168] S901. The terminal side device monitors the LP-WUS in a first time period based on a first monitoring mode. The first monitoring mode is used to indicate that the LP-WUS is monitored in at least one first monitoring occasion MO, or is used to indicate that the LP-WUS is not monitored in at least one second MO; the first time period includes part or all of the sleep period of the DRX cycle.

[0169] The DRX cycle is configured by the network side device for the terminal side device in advance, and can refer to the DRX cycle shown in FIG. 8, which will not be described again. In addition, the first time period includes part or all of the sleep period of the DRX cycle, and the first time period can include one or more slots, one or more mini-slots, one or more symbols, etc. For the convenience of description, the first time period includes m slots is taken as an example for description below, and m is a positive integer.

[0170] In an optional implementation, the first time period is pre-configured with one or more monitoring occasions (MOs), which can be used to monitor the LP-WUS. Optionally, the MO can also be referred to as an LP-WUS MO, and the naming of the embodiments of the present application is not limited.

[0171] In addition, the one or more MOs configured in the first time period can be continuous or discontinuous. For example, FIG. 10 is a schematic diagram of an MO. As shown in FIG. 10, the first time period includes one sleep period of the DRX cycle, and the four slots included in the first time period are all configured as MOs that can be used to monitor the LP-WUS, so that the four MOs configured in the first time period are continuous, or understood as that the terminal side device can monitor the LP-WUS on each slot in the first time period.

[0172] For another example, FIG. 11 is a schematic diagram of another MO. As shown in FIG. 11, the first time period includes one sleep period of the DRX cycle, and the first slot and the third slot of the four slots included in the first time period are configured as MOs that can be used to monitor the LP-WUS, so that the two MOs configured in the first time period are discontinuous, or understood as that the terminal side device cannot monitor the LP-WUS on each slot in the first time period.

[0173] Optionally, the one or more MOs pre-configured in the first time period can be configured by the network side device for the terminal side device through the MR module, and correspondingly, the terminal side device receives the one or more MOs configured by the network side device for the first time period through the MR module. Optionally, the one or more MOs pre-configured in the first time period can be configured by the network side device for the terminal side device through the LR module, and correspondingly, the terminal side device receives the one or more MOs configured by the network side device for the first time period through the LR module.

[0174] It can be seen that the network side device can flexibly configure one or more MOs in the first time period for the terminal side device to monitor the LP-WUS, and this manner is conducive to the terminal side device monitoring the LP-WUS by using the configured MOs. However, which MOs in the first time period are specifically used by the terminal side device to monitor the LP-WUS can be determined based on a monitoring mode, such as monitoring the LP-WUS based on a first monitoring mode in the first time period, which is described below:

[0175] In an optional implementation, the first monitoring mode is used to indicate monitoring the LP-WUS on at least one first MO in the first time period.

[0176] Specifically, the first monitoring mode is used to indicate monitoring the LP-WUS on at least one first MO of the one or more MOs configured in the first time period, or in other words, the first monitoring mode is specifically used to indicate monitoring at least one first MO of the one or more MOs configured in the first time period.

[0177] For example, the first time period includes 20 slots, and the 11th to 20th slots in the first time period are configured as MOs that can be used to monitor the LP-WUS, and the first monitoring mode is used to indicate monitoring the LP-WUS on the 1st, 3rd, 5th, 7th, and 9th MOs of the MOs configured in the first time period, or in other words, the first monitoring mode is used to indicate monitoring the LP-WUS on the 1st, 3rd, 5th, 7th, and 9th slots of the 11th to 20th slots configured as MOs in the first time period.

[0178] For another example, the first time period includes 20 slots, and all the 20 slots in the first time period are configured as MOs that can be used to monitor the LP-WUS, and the first monitoring mode is used to indicate monitoring the LP-WUS on the 1st, 3rd, 5th, 7th, and 9th odd MOs of the 20 MOs in the first time period, or in other words, the first monitoring mode is used to indicate monitoring the LP-WUS on the 1st, 3rd, 5th, 7th, and 9th odd slots of the 20 slots in the first time period.

[0179] For another example, the first time period includes 10 slots, and the 1st, 3rd, 5th, 7th, and 9th slots in the first time period are configured as MOs that can be used to monitor the LP-WUS, and the first monitoring mode is used to indicate monitoring the LP-WUS on the 2nd and 4th MOs of the 5 MOs configured in the first time period, or in other words, the first monitoring mode is used to indicate monitoring the LP-WUS on the 2nd and 4th slots of the 5 slots configured as MOs in the first time period, or in other words, the first monitoring mode is used to indicate monitoring the LP-WUS on the 3rd slot and the 7th slot in the first time period.

[0180] For another example, the first time period includes 10 slots, and the 10 slots are all configured as MOs that can be used to monitor the LP-WUS, the first monitoring mode is used to indicate to monitor the LP-WUS on the first MO of every 3 MOs configured in the first time period, or in other words, the first monitoring mode is used to indicate to monitor the LP-WUS on the first slot of every 3 slots of the 10 slots in the first time period, or in other words, the first monitoring mode is used to indicate to monitor the LP-WUS on the 1st, 4th, 7th slots in the first time period.

[0181] For another example, the first time period includes 20 slots, and the 20 slots are all configured as MOs that can be used to monitor the LP-WUS, the first monitoring mode is used to indicate to monitor the LP-WUS on the 2nd, 4th, 6th, 8th, 10th, 12th, 14th, 16th, 18th, 20th MOs of the 20 MOs configured in the first time period, i.e., to skip the 1st and 3rd MOs of every 4 MOs configured in the first time period, or in other words, the first monitoring mode is used to indicate to monitor the LP-WUS on the 2nd, 4th, 6th, 8th, 10th, 12th, 14th, 16th, 18th, 20th slots of the 20 slots in the first time period, i.e., to skip the 1st and 3rd slots of every 4 slots of the 20 slots in the first time period.

[0182] In another optional implementation, the first monitoring mode is used to indicate not to monitor the LP-WUS on at least one second MO in the first time period. Or in other words, the first monitoring mode is used to indicate not to monitor at least one second MO of the one or more MOs configured in the first time period.

[0183] For example, the first time period includes 20 slots, and the 11th to 20th slots in the first time period are configured as MOs, the first monitoring mode is used to indicate not to monitor the LP-WUS on the 1st, 3rd, 5th, 7th, 9th MOs of the 10 MOs configured in the first time period, or in other words, the first monitoring mode is used to indicate not to monitor the LP-WUS on the 1st, 3rd, 5th, 7th, 9th slots of the 11th to 20th slots configured as MOs in the first time period.

[0184] For another example, the first time period includes 20 slots, and the 20 slots in the first time period are all configured as MOs, and the first monitoring mode is used to indicate not monitoring LP-WUS on even-numbered MOs, e.g., 2nd, 4th, 6th, 8th, 10th, etc., MOs among the 20 MOs configured in the first time period, or in other words, the first monitoring mode is used to indicate not monitoring LP-WUS on even-numbered slots, e.g., 2nd, 4th, 6th, 8th, 10th, etc., slots among the 20 slots in the first time period.

[0185] For another example, the first time period includes 10 slots, and the 1st, 3rd, 5th, 7th, 9th slots in the first time period are configured as MOs, and the first monitoring mode is used to indicate not monitoring LP-WUS on the 2nd and 4th MOs among the 5 MOs configured in the first time period, or in other words, the first monitoring mode is used to indicate not monitoring LP-WUS on the 2nd and 4th slots among the 5 slots configured as MOs in the first time period, or in other words, the first monitoring mode is used to indicate not monitoring LP-WUS on the 3rd and 7th slots in the first time period.

[0186] For another example, the first time period includes 10 slots, and the 10 slots are all configured as MOs that can be used to monitor LP-WUS, and the first monitoring mode is used to indicate skipping one MO among every 3 MOs to not monitor LP-WUS among the 10 MOs configured in the first time period, or in other words, the first monitoring mode is used to indicate not monitoring LP-WUS on the 4th and 8th MOs among the 10 MOs configured in the first time period, or in other words, the first monitoring mode is used to indicate skipping one slot among every 3 slots to not monitor LP-WUS in the first time period, or in other words, the first monitoring mode is used to indicate not monitoring LP-WUS on the 4th and 8th slots in the first time period.

[0187] In another optional implementation, the first time period is not pre-configured with one or more MOs that can be used to monitor LP-WUS. In this way, the first monitoring mode is used to indicate which resources in the first time period to monitor LP-WUS, and the resources in the first time period to monitor LP-WUS indicated by the first monitoring mode are referred to as first MOs. Therefore, the first monitoring mode is used to indicate monitoring LP-WUS on at least one first MO in the first time period.

[0188] For example, the first time period includes 10 slots, and the first monitoring mode is used to indicate monitoring LP-WUS on the 1st, 3rd, 5th, 7th, and 9th slots in the 10 slots, and the 1st, 3rd, 5th, 7th, and 9th slots in the 10 slots are referred to as a first MO for monitoring LP-WUS. For another example, the first time period includes 10 slots, and the first monitoring mode is used to indicate monitoring LP-WUS on the 1st, 3rd, 6th, and 9th slots in the 10 slots, and the 1st, 3rd, 6th, and 9th slots in the 10 slots are referred to as the first MO.

[0189] In another optional implementation, in a case where the first time period is not pre-configured in a manner of one or more MOs that can be used to monitor LP-WUS, the first monitoring mode is used to indicate which resources in the first time period are not used to monitor LP-WUS, and the resources indicated by the first monitoring mode to not monitor LP-WUS are referred to as a second MO. Therefore, the first monitoring mode is used to indicate not monitoring LP-WUS on at least one second MO in the first time period.

[0190] For example, the first time period includes 10 slots, and the first monitoring mode is used to indicate not monitoring LP-WUS on the 2nd, 4th, 6th, 8th, and 10th slots in the 10 slots, and the 2nd, 4th, 6th, 8th, and 10th slots in the 10 slots are referred to as a second MO for not monitoring LP-WUS.

[0191] Optionally, the first monitoring mode can also be referred to as a first monitoring method, and the naming of the embodiments of the present application is not limited.

[0192] In summary, the first monitoring mode is used to indicate monitoring LP-WUS on at least one first MO in the first time period, or is used to indicate not monitoring LP-WUS on at least one second MO in the first time period. Therefore, the terminal-side device can monitor LP-WUS in the first time period based on the first monitoring mode.

[0193] In an optional implementation, the terminal-side device monitors LP-WUS in the first time period based on the first monitoring mode, including: determining, based on the first monitoring mode, a MO for monitoring LP-WUS in the first time period; and monitoring LP-WUS on the determined MO. The terminal-side device monitors LP-WUS on the determined MO refers to monitoring whether there is LP-WUS on the determined MO. The terminal-side device may or may not monitor LP-WUS on the determined MO.

[0194] In a possible manner, the first monitoring mode is used to indicate that the at least one first MO indicated by the first monitoring mode is the MO of the terminal-side device for monitoring the LP-WUS in the first time period. Therefore, the terminal-side device determines the MO for monitoring the LP-WUS in the first time period based on the first monitoring mode, including: determining the at least one first MO indicated by the first monitoring mode as the MO for monitoring the LP-WUS in the first time period. In other words, the terminal-side device monitors the LP-WUS in the first time period based on the first monitoring mode, including: monitoring the LP-WUS on the at least one first MO in the first time period indicated by the first monitoring mode.

[0195] For example, the first time period includes 10 slots, and the 10 slots are all pre-configured as the MOs that can be used to monitor the LP-WUS, and the first monitoring mode is used to indicate that the 3rd, 6th and 9th MOs of the 10 MOs configured in the first time period are used to monitor the LP-WUS. In this case, the terminal-side device monitors the LP-WUS on the 3rd, 6th and 9th MOs in the first time period, i.e., the terminal-side device monitors the LP-WUS on the 3rd, 6th and 9th slots in the first time period.

[0196] In another possible manner, the first monitoring mode is used to indicate that the at least one second MO in the first time period is not used to monitor the LP-WUS, and the MOs in the first time period except the at least one second MO indicated by the first monitoring mode are used to monitor the LP-WUS. Therefore, the terminal-side device determines the MO for monitoring the LP-WUS in the first time period based on the first monitoring mode, including: determining the MO for monitoring the LP-WUS in the first time period based on the at least one second MO indicated by the first monitoring mode. Thus, the terminal-side device monitors the LP-WUS on the determined MO.

[0197] For example, the first time period includes 10 slots, and the 1st, 3rd, 5th, 7th and 9th slots in the first time period are configured as the MOs, and the first monitoring mode is used to indicate that the 2nd MO and the 4th MO of the 5 MOs configured in the first time period are not used to monitor the LP-WUS. In this case, the terminal-side device determines the MO for monitoring the LP-WUS in the first time period based on the first monitoring mode, including: determining the 1st, 3rd and 5th MOs of the 5 MOs configured in the first time period as the MOs for monitoring the LP-WUS, i.e., the 1st, 5th and 9th slots in the first time period, and thus the terminal-side device monitors the LP-WUS on the 1st, 5th and 9th slots in the first time period.

[0198] In addition, the MO determined by the terminal-side device to monitor the LP-WUS in the first time period based on the first monitoring mode can be referred to as an activated MO, or can be referred to as an activated LP-WUS MO. Correspondingly, the MO without monitoring the LP-WUS in the first time period can be referred to as an inactivated MO, or can be referred to as an inactivated LP-WUS MO.

[0199] For example, the 10 slots included in the first time period are all configured as MOs, and the first monitoring mode is used to indicate that the 1st, 2nd, 3rd, 4th, and 5th MOs of the 10 MOs configured in the first time period monitor the LP-WUS. In this case, the 1st, 2nd, 3rd, 4th, and 5th MOs in the first time period are activated MOs, and the 6th, 7th, 8th, 9th, and 10th MOs in the first time period are inactivated MOs.

[0200] For another example, the 10 slots included in the first time period are all configured as MOs, and the first monitoring mode is used to indicate that the 2nd, 4th, 6th, 8th, and 10th MOs of the 10 MOs configured in the first time period do not monitor the LP-WUS. In this case, the 1st, 3rd, 5th, 7th, and 9th MOs in the first time period are activated MOs, and the 2nd, 4th, 6th, 8th, and 10th MOs in the first time period are inactivated MOs.

[0201] In summary, in the manner in which the first monitoring mode is used to indicate to monitor the LP-WUS on at least one first MO in the first time period, the terminal-side device can directly monitor the LP-WUS on the at least one first MO indicated by the first monitoring mode. In the manner in which the first monitoring mode is used to indicate not to monitor the LP-WUS on at least one second MO in the first time period, the terminal-side device determines the MO to monitor the LP-WUS in the first time period based on the at least one second MO indicated by the first monitoring mode, and then monitors the LP-WUS on the determined MO.

[0202] In an optional implementation, the terminal-side device determines, based on the first monitoring mode, that there is no MO for monitoring the LP-WUS. In this mode, the terminal-side device does not monitor the LP-WUS in the first time period based on the first monitoring mode. For example, the first time period includes 10 slots, each of which is configured as a MO for monitoring the LP-WUS, and the first monitoring mode is used to indicate that the LP-WUS is not monitored in the 10 MOs configured in the first time period. Therefore, the terminal-side device determines, based on the first monitoring mode, that there is no MO for monitoring the LP-WUS, and thus does not monitor the LP-WUS in the 10 slots in the first time period.

[0203] In addition, the first time period includes part or all of the sleep period of the DRX cycle. Therefore, the terminal-side device monitors the LP-WUS in the first time period based on the first monitoring mode. It can be understood that the terminal-side device can monitor the LP-WUS in part or all of the sleep period of the DRX cycle based on the first monitoring mode. Therefore, the terminal-side device can monitor the PDCCH based on the monitored LP-WUS in part or all of the sleep period of the DRX cycle, which can reduce the probability of missing data while reducing the power consumption of the terminal-side device compared with not monitoring the PDCCH in the sleep period of the DRX cycle.

[0204] In an optional implementation, the first time period further includes at least one of the following: part or all of the active period of the DRX cycle, part or all of the active period of the monitoring cycle.

[0205] The monitoring cycle is a cycle composed of a MO for monitoring the LP-WUS and a MO for not monitoring the LP-WUS. Alternatively, the monitoring cycle includes an active period for monitoring the LP-WUS and a non-active period for not monitoring the LP-WUS, wherein the active period for monitoring the LP-WUS includes one or more MOs for monitoring the LP-WUS, and the non-active period for monitoring the LP-WUS includes one or more MOs for not monitoring the LP-WUS. Therefore, the active period of the monitoring cycle is a time period in which the MO for monitoring the LP-WUS is located, and the non-active period of the monitoring cycle is a time period in which the MO for not monitoring the LP-WUS is located. In addition, the cycle time of the monitoring cycle and the DRX cycle can be the same or different.

[0206] The first time period further includes part or all of the active period of the DRX cycle, indicating that the terminal-side device can monitor the LP-WUS in part or all of the active period of the DRX cycle based on the first monitoring mode. In this way, in the case that a timer used for timing the monitoring of the PDCCH expires or is closed in advance in the active period of the DRX cycle, the terminal-side device can monitor the LP-WUS in part or all of the active period of the DRX cycle based on the first monitoring mode, and then can monitor the PDCCH based on the monitored LP-WUS in part or all of the active period of the DRX cycle, thereby reducing the probability of data missing due to the inability to monitor the PDCCH because the timer expires or is closed in advance.

[0207] The first time period further includes part or all of the active period of the monitoring cycle, indicating that the terminal-side device can monitor the LP-WUS in part or all of the MOs that need to monitor the LP-WUS, thereby reducing the probability of not monitoring the LP-WUS, and further reducing the probability of the terminal-side device missing data.

[0208] In another optional embodiment, the first time period further includes the active period of the transmission cycle. The transmission cycle is a cycle associated with the LR module of the terminal-side device, or in other words, the transmission cycle is a cycle pre-configured by the network-side device for the LR module of the terminal-side device, or in other words, in the active period of the transmission cycle, the terminal-side device uses the LR module to receive signals; in the sleep period of the transmission cycle, the terminal-side device does not use the LR module to receive signals. In this way, the DRX cycle in the embodiments of the present application can also be regarded as a cycle pre-configured by the network-side device for the MR module of the terminal-side device, or in other words, the DRX cycle is a cycle used when the terminal-side device uses the MR module to receive data, or in other words, the DRX cycle is associated with the MR module of the terminal-side device.

[0209] In addition, the active period of the transmission cycle includes at least one of part or all of the sleep period of the DRX cycle and part of the active period of the DRX cycle. When the active period of the transmission cycle includes part or all of the sleep period of the DRX cycle, the first time period includes part or all of the sleep period of the DRX cycle, so that the terminal-side device can monitor the LP-WUS in part of the sleep period of the DRX cycle, and then can monitor the PDCCH based on the monitored LP-WUS, thereby reducing the probability of data missing. When the active period of the transmission cycle includes part of the active period of the DRX cycle, the first time period includes part of the active period of the DRX cycle, which is beneficial to the case that a timer used for timing the monitoring of the PDCCH expires or is closed in advance in the active period of the DRX cycle, so that the terminal-side device can monitor the LP-WUS in part of the active period of the DRX cycle, and then can reduce the probability of the terminal-side device missing data.

[0210] For example, FIG. 12 is a schematic diagram of a cycle. As shown in FIG. 12, the transmission cycle is a cycle associated with the LR module of the terminal-side device, the DRX cycle is a cycle associated with the MR module of the terminal-side device, the first time period includes the active period of the transmission cycle, the active period of the transmission cycle includes the partial active period of the DRX cycle and the partial sleep period of the DRX cycle, so that the first time period includes the partial active period of the DRX cycle and the partial sleep period of the DRX cycle, and then the terminal-side device can monitor the LP-WUS based on the first monitoring mode in the partial active period of the DRX cycle and the partial sleep period of the DRX cycle, so as to reduce the probability of data missing.

[0211] Optionally, the first time period further includes the active period of the transmission cycle, and the active period of the transmission cycle can include one or more MOs for monitoring the LP-WUS. The MOs in the active period of the transmission cycle for monitoring the LP-WUS can be configured by the network-side device for the terminal-side device in advance, such as being configured by the network-side device for the terminal-side device through a non-low-power signal in the active period of the DRX cycle, or being configured by the network-side device for the terminal-side device through a low-power signal in the sleep period of the DRX cycle, or being configured by the network-side device for the terminal-side device through a low-power signal in the active period of the transmission cycle.

[0212] Optionally, the first time period includes the partial or entire sleep period of the DRX cycle, and at least one of the following: the partial or entire active period of the monitoring cycle, the active period of the transmission cycle, and the terminal-side device can monitor the LP-WUS based on the first monitoring mode in the first time period through the LR module. Optionally, the first time period further includes the partial or entire active period of the DRX cycle, and the terminal-side device can monitor the LP-WUS based on the first monitoring mode in the partial or entire active period of the DRX cycle included in the first time period through the MR module.

[0213] In an optional implementation, the LP-WUS monitored by the terminal-side device is used to indicate at least one of the following: listening to the PDCCH or not listening to the PDCCH in the second time period, the range of listening to the PDCCH in the second time period, and the range of not listening to the PDCCH in the second time period. The second time period is part or all of the first time period.

[0214] In addition, the second time period can be a slot, a mini-slot, or a period of time defined / preconfigured by a protocol, and the embodiments of the present application do not limit this.

[0215] For example, the second time period can be understood as an absolute time period of 1 ms, 0.5 ms, 0.25 ms, etc. For another example, the second time period can be understood as a time period in which a plurality of symbols are predefined by a protocol, such as 14 symbols, that is, the concept of a slot in NR; or 2 / 3 / 4 / 5 / 6 / 7… symbols, that is, the concept of a mini-slot in NR. For another example, the second time can be understood as a time period related to a subcarrier spacing, such as 14 OFDM symbols when the subcarrier spacing is 15 KHz; or 28 OFDM symbols when the subcarrier spacing is 30 KHz; or 56 OFDM symbols when the subcarrier spacing is 60 KHz; or 14*n OFDM symbols when the subcarrier spacing is 15*n KHz, n being a positive integer.

[0216] For example, the first time period includes 5 slots, and the LP-WUS monitored by the terminal-side device on the second slot in the first time period is used to indicate that the PDCCH is monitored in the second time period, and the second time period is the fourth and fifth slots in the first time period. It indicates that the network-side device can schedule burst services through the PDCCH on the fourth and fifth slots in the first time period. Therefore, the terminal-side device monitors the PDCCH on the fourth and fifth slots in the first time period to receive the burst services that the network-side device can schedule, so as to reduce the probability of data missing detection while reducing the power consumption of the terminal-side device.

[0217] For another example, the first time period includes 10 slots, and the LP-WUS monitored by the terminal-side device on the second slot in the first time period is used to indicate that the PDCCH is monitored in the second time period, and the second time period is the sixth to tenth slots in the first time period. The range of the PDCCH monitored in the second time period indicated by the monitored LP-WUS is the third to fifth slots in the second time period. It indicates that the network-side device can schedule burst services through the PDCCH on the third to fifth slots in the second time period. Therefore, the terminal-side device monitors the PDCCH on the third to fifth slots in the second time period, or the network-side device can schedule burst services through the PDCCH on the eighth to tenth slots in the first time period. Therefore, the terminal-side device monitors the PDCCH on the eighth to tenth slots in the first time period.

[0218] In an optional implementation, the first monitoring mode used by the terminal-side device to monitor the LP-WUS in the first time period is pre-configured by the network-side device for the terminal-side device. The network-side device can configure the first monitoring mode for the terminal-side device in a plurality of ways, two configuration ways are described as follows:

[0219] Configuration mode one: the network side device configures the first monitoring mode for the terminal side device through the first configuration information.

[0220] Specifically, the network side device sends the first configuration information, and the first configuration information is used to configure the first monitoring mode. Correspondingly, the terminal side device receives the first configuration information.

[0221] In a possible manner, the first configuration information is carried in a non-low-power signal in an active period of a DRX cycle, or carried in a low-power signal in a sleep period or an active period of the DRX cycle. The non-low-power signal may, for example, be carried in downlink control information (DCI) in a PDCCH, carried in RRC signaling, or carried in a medium access control control element (MAC CE), and the present application does not limit the same. The low-power signal is described above and will not be repeated here.

[0222] In addition, when the first configuration information is carried in the non-low-power signal in the active period of the DRX cycle, the first configuration information can be received by the terminal side device through the MR module. When the first configuration information is carried in the low-power signal in the sleep period or the active period of the DRX cycle, the first configuration information can be received by the terminal side device through the LR module.

[0223] In another possible manner, the first configuration information is carried in a low-power signal in an active period of a monitoring cycle. In yet another possible manner, the first configuration information is carried in a low-power signal in an active period of a transmission cycle. When the first configuration information is carried in the low-power signal in the active period of the monitoring cycle, or the first configuration information is carried in the low-power signal in the active period of the transmission cycle, the first configuration information can be received by the terminal side device through the LR module, which can save energy.

[0224] In an optional implementation, the network side device further sends first indication information, and the first indication information is used to indicate to activate the first monitoring mode. Correspondingly, the terminal side device receives the first indication information.

[0225] In a possible manner, the first indication information is specifically used to indicate to activate the first monitoring mode in one or more first time periods, or the first indication information is specifically used to indicate to activate the first monitoring mode in part or all of a first time period.

[0226] In another possible implementation, the first indication information is specifically used to indicate that the first monitoring mode is activated in one or more sleep periods of a DRX cycle, or the first indication information is specifically used to indicate that the first monitoring mode is activated in the sleep periods of one or more DRX cycles.

[0227] In another possible implementation, the first indication information is specifically used to indicate that the first monitoring mode is activated in one or more active periods of a monitoring cycle, or the first indication information is specifically used to indicate that the first monitoring mode is activated in the active periods of one or more monitoring cycles.

[0228] In another possible implementation, the first indication information is specifically used to indicate that the first monitoring mode is activated in one or more active periods of a transmission cycle, or the first indication information is specifically used to indicate that the first monitoring mode is activated in the active periods of one or more transmission cycles.

[0229] Regardless of how the first indication information is specifically used to indicate the activation of the first monitoring mode, the terminal-side device activates the first monitoring mode based on the first indication information. For example, when the first indication information is specifically used to indicate the activation of the first monitoring mode in one or more first time periods, it indicates that the first monitoring mode is applicable to the one or more first time periods, and the terminal-side device activates the first monitoring mode in the one or more first time periods based on the first indication information, so that the terminal-side device can monitor the LP-WUS based on the first monitoring mode in the one or more first time periods. For another example, when the first indication information is specifically used to indicate the activation of the first monitoring mode in one or more active periods of a monitoring cycle, it indicates that the first monitoring mode is applicable to the one or more active periods of the monitoring cycle, and the terminal-side device activates the first monitoring mode in the one or more active periods of the monitoring cycle based on the first indication information, so that the terminal-side device can monitor the LP-WUS based on the first monitoring mode in the one or more active periods of the monitoring cycle.

[0230] The first indication information can indicate the activation of the first monitoring mode in various manners, which are not limited in the embodiments of the present application. In one possible implementation, the first indication information indicates the activation of the first monitoring mode in an implicit manner, such as implicitly indicating the activation of the first monitoring mode through bit information. For example, when the bit information of the first indication information is 1, it is used to indicate the activation of the first monitoring mode. For another example, when the bit information of the first indication information is 0, it is used to indicate the activation of the first monitoring mode.

[0231] In another possible mode, the first indication information indicates to activate the first monitoring mode in a display manner, such as by including an identifier of the first monitoring mode. The identifier of the first monitoring mode can be configured by the network side device for the terminal side device when the network side device configures the first monitoring mode for the terminal side device. For example, the first monitoring mode is monitoring mode a, and the first indication information includes an identifier of monitoring mode a, which indicates to activate monitoring mode a.

[0232] In another possible mode, the first indication information indicates to activate the first monitoring mode in a display manner, such as by including an identifier of the first monitoring mode. The identifier of the first monitoring mode can be configured by the network side device for the terminal side device when the network side device configures the first monitoring mode for the terminal side device. For example, the first monitoring mode is monitoring mode a, and the first indication information includes an identifier of monitoring mode a, which indicates to activate monitoring mode a.

[0233] In another possible mode, the first indication information indicates to activate the first monitoring mode in a display manner, such as by including an identifier of the first monitoring mode. The identifier of the first monitoring mode can be configured by the network side device for the terminal side device when the network side device configures the first monitoring mode for the terminal side device. For example, the first monitoring mode is monitoring mode a, and the first indication information includes an identifier of monitoring mode a, which indicates to activate monitoring mode a.

[0234] The first indication information is used to indicate that the first monitoring mode is activated in one or more active periods of a monitoring period, or is used to indicate that the first monitoring mode is activated in an active period of one or more monitoring periods, or is used to indicate that the first monitoring mode is activated in one or more active periods of a transmission period, or is used to indicate that the first monitoring mode is activated in an active period of one or more transmission periods. For details of the specific indication manner of the first indication information when the first indication information is used to indicate that the first monitoring mode is activated in one or more sleep periods of a DRX period or is used to indicate that the first monitoring mode is activated in a sleep period of one or more DRX periods, refer to the indication manner, which will not be described herein again.

[0235] In addition, the first indication information can be carried in various forms, and embodiments of the present application do not limit this. In one possible manner, the first indication information is carried in a non-low-power signal in an active period of a DRX period. The non-low-power signal can refer to the above description, which will not be described herein again.

[0236] For example, FIG. 13 is a schematic diagram of a first indication information. As shown in FIG. 13, the first indication information is carried in a PDCCH in an active period of a DRX period, and the first indication information is used to indicate that the first monitoring mode is activated. The first monitoring mode indicates that the LP-WUS is monitored on the first slot and the third slot in the first time period. That is, the network side device indicates the terminal side device to activate the first monitoring mode through the first indication information carried in the PDCCH in the DRX active period, so that the terminal side device can monitor the LP-WUS on the first slot and the third slot in the first time period. In addition, the first slot and the third slot in FIG. 13 can be referred to as activated MOs, and the second slot and the fourth slot can be referred to as non-activated MOs. The activated MOs and the non-activated MOs in FIGS. 14 to 16 described below are defined according to this meaning, which will not be described herein again.

[0237] For another example, FIG. 14 is a schematic diagram of another first indication information. In FIG. 14, two first time periods are included, a first one of the first time periods includes a sleep period a of a DRX cycle, and a second one of the first time periods includes a sleep period b of the DRX cycle, the first indication information is carried in a PDCCH in an active period of the DRX cycle, and the first indication information is used to indicate that the first monitoring mode is activated in the two sleep periods of the DRX cycle, and the first monitoring mode is used to indicate that the LP-WUS is monitored on 4 slots in the first time period. That is, the network side device indicates the terminal side device to activate the first monitoring mode in the two sleep periods of the DRX cycle by the first indication information carried in the PDCCH in the active period of the DRX cycle. Thus, the terminal side device can monitor the LP-WUS based on the first monitoring mode in the first one of the first time periods and the second one of the first time periods, or the terminal side device can monitor the LP-WUS based on the first monitoring mode on the 4 slots in the first one of the first time periods and on the 4 slots in the second one of the first time periods.

[0238] Optionally, when the first indication information is carried in the low power consumption signal in the active period of the DRX cycle, the first indication information can be received by the terminal side device through the MR module, and correspondingly, the first indication information is sent by the network side device through the MR module.

[0239] In another possible manner, the first indication information is carried in the low power consumption signal in the sleep period or the active period of the DRX cycle, and the low power consumption signal can be referred to the above description and will not be repeated. For example, FIG. 15 is a schematic diagram of another first indication information. In FIG. 15, two first time periods are included, and the first indication information is carried in the LP-WUS in the sleep period of the DRX cycle included in the first one of the first time periods, and the first indication information is used to indicate that the first monitoring mode is activated in the second one of the first time periods, and the first monitoring mode is used to indicate that the LP-WUS is monitored on the 1st slot and the 4th slot in the second one of the first time periods. That is, the network side device indicates the terminal side device to activate the first monitoring mode in the second one of the first time periods by the first indication information carried in the LP-WUS signal in the sleep period of the DRX cycle. Thus, the terminal side device can monitor the LP-WUS based on the first monitoring mode on the 1st slot and the 4th slot in the second one of the first time periods.

[0240] Optionally, when the first indication information is carried in the low power consumption signal in the sleep period or the active period of the DRX cycle, the first indication information can be received by the terminal side device through the LR module, and correspondingly, the first indication information is sent by the network side device through the LR module. This manner can reduce the energy consumption.

[0241] In another possible mode, the first indication information is carried in a low-power signal in the active period of the monitoring period. In another possible mode, the first indication information is carried in a low-power signal in the active period of the transmission period. That is, the network-side device can send the first indication information to the terminal-side device by a low-power signal, such as an LP-WUS, in the active period of the monitoring period or in the active period of the transmission period, to instruct the terminal-side device to activate the first monitoring mode. In this mode, the terminal-side device can receive the first indication information through the LR module, and the energy consumption can be reduced.

[0242] It can be seen that the first indication information can be carried in a non-low-power signal in the active period of the DRX period, or can be carried in a low-power signal in the sleep period or the active period of the DRX period, or can be carried in a low-power signal in the active period of the monitoring period or the transmission period. In this mode, the network-side device does not need to carry the first indication information through an additional signal, and the signaling overhead can be reduced.

[0243] In another optional implementation, the terminal-side device activates the first monitoring mode when entering the partial or entire sleep period of the DRX period. Correspondingly, for the network-side device, the network-side device defaults that the terminal-side device activates the first monitoring mode when the terminal-side device enters the partial or entire sleep period of the DRX period, and thus sends the LP-WUS for the terminal-side device based on the first monitoring mode in the first time period.

[0244] In another optional implementation, the terminal-side device activates the first monitoring mode when entering the partial or entire active period of the monitoring period. Correspondingly, for the network-side device, the network-side device defaults that the terminal-side device activates the first monitoring mode when the terminal-side device enters the partial or entire active period of the monitoring period, and thus sends the LP-WUS for the terminal-side device based on the first monitoring mode in the first time period.

[0245] In another optional implementation, the terminal-side device activates the first monitoring mode when entering the partial or entire active period of the transmission period. Correspondingly, for the network-side device, the network-side device defaults that the terminal-side device activates the first monitoring mode when the terminal-side device enters the partial or entire active period of the transmission period, and thus sends the LP-WUS for the terminal-side device based on the first monitoring mode in the first time period.

[0246] It can be seen that the terminal-side device can activate the first monitoring mode by entering the partial or entire sleep period of the DRX period, or entering the partial or entire active period of the monitoring period, or entering the partial or entire active period of the transmission period. In this mode, the network-side device does not need to instruct the terminal-side device to activate the first monitoring mode through a signal / signaling, and the signaling overhead can be reduced.

[0247] In another alternative implementation, the terminal-side device triggers the activation of the first monitoring mode by sending an uplink signal. Specifically, the terminal-side device sends a first uplink signal, and the first uplink signal is used to trigger the activation of the first monitoring mode. Correspondingly, the network-side device receives the first uplink signal. Thus, the network-side device can learn from the first uplink signal that the terminal-side device has activated the first monitoring mode in the first time period, and then send the LP-WUS for the terminal-side device based on the first monitoring mode in the first time period.

[0248] In one possible way, the first uplink signal can be any of the following: a scheduling request (SR), a buffer status report (BSR), msg1, msg3, and activation assistance information. In this way, the terminal-side device can send the first uplink signal through the MR module, and correspondingly, the network-side device can receive the first uplink signal through the MR module.

[0249] In another possible way, the first uplink signal can be a low-power consumption signal, which is described above and will not be repeated. In this way, the terminal-side device can send the low-power consumption signal to the network-side device through the LR module, and correspondingly, the network-side device can receive the first uplink signal through the LR module.

[0250] In addition, the terminal-side device autonomously activates the first monitoring mode when it enters part or all of the sleep period of the DRX cycle, or when it enters part or all of the active period of the monitoring cycle, or when it enters part or all of the active period of the transmission cycle, and the terminal-side device triggers the activation of the first monitoring mode by sending the first uplink signal. Both of these can be regarded as the terminal-side device triggering the activation of the first monitoring mode by an event.

[0251] As can be seen, after the network-side device configures the first monitoring mode for the terminal-side device through the first configuration information, it can also instruct the terminal-side device to activate the first monitoring mode through the first indication information, so that the terminal-side device monitors the LP-WUS in the first time period based on the activated first monitoring mode. Alternatively, after the network-side device configures the first monitoring mode for the terminal-side device through the first configuration information, the terminal-side device autonomously activates the first monitoring mode through an event-triggered manner, so as to monitor the LP-WUS in the first time period based on the activated first monitoring mode.

[0252] Configuration Mode Two: The network-side device configures multiple monitoring modes for the terminal-side device through configuration information, and the multiple monitoring modes include the first monitoring mode.

[0253] Specifically, the network-side device sends first configuration information, and the first configuration information is used for configuring a plurality of monitoring modes, and the plurality of monitoring modes include a first monitoring mode. Correspondingly, the terminal-side device receives the first configuration information.

[0254] Different monitoring modes in the plurality of monitoring modes are different. Specifically, the MOs for monitoring the LP-WUS in the first time period indicated by different monitoring modes in the plurality of monitoring modes are different. Alternatively, the MOs for not monitoring the LP-WUS in the first time period indicated by different monitoring modes in the plurality of monitoring modes are different.

[0255] For example, the first time period includes 10 slots, and the 10 slots are all configured as the MOs that can be used for monitoring the LP-WUS, the plurality of monitoring modes include a monitoring mode a and a monitoring mode b, the monitoring mode a indicates monitoring the LP-WUS on the 1st, 3rd, 5th, 7th and 9th MOs in the first time period, and the monitoring mode b indicates monitoring the LP-WUS on the 2nd, 4th, 6th, 8th and 10th MOs in the first time period.

[0256] Optionally, the first configuration information is carried in a non-low-power signal in an active period of a DRX cycle, or carried in a low-power signal in an active period or a sleep period of a DRX cycle, or carried in a low-power signal in an active period of a monitoring cycle, or carried in a low-power signal in an active period of a transmission cycle. For details, refer to the configuration mode one described above, and details are not repeated here.

[0257] In an optional embodiment, the network-side device further sends first indication information, and the first indication information is used for indicating activating the first monitoring mode in the plurality of monitoring modes. Correspondingly, the terminal-side device receives the first indication information. Optionally, the terminal-side device further activates the first monitoring mode in the plurality of monitoring modes based on the first indication information, so as to monitor the LP-WUS in the first time period based on the activated first monitoring mode.

[0258] In addition, the first indication information can indicate activating the first monitoring mode in the plurality of monitoring modes in a plurality of ways, which is not limited in the embodiments of the present application. In a possible way, the first indication information can indicate activating the first monitoring mode in the plurality of monitoring modes in an implicit indication manner, such as indicating activating the first monitoring mode in the plurality of monitoring modes by a bit information, or such as indicating activating the first monitoring mode in the plurality of monitoring modes by a bitmp.

[0259] For example, the multiple monitoring modes include monitoring mode a and monitoring mode b, the bit information of the first indication information is 0, which is used to indicate that the monitoring mode a is activated; the bit information of the first indication information is 1, which is used to indicate that the monitoring mode b is activated. For another example, the bit information of the first indication information is 0, which is used to indicate that the monitoring mode b is activated; the bit information of the first indication information is 1, which is used to indicate that the monitoring mode a is activated.

[0260] For another example, the multiple monitoring modes include monitoring mode a, monitoring mode b, monitoring mode c and monitoring mode d, the bit information of the first indication information is 00, which is used to indicate that the monitoring mode a is activated; the bit information of the first indication information is 01, which is used to indicate that the monitoring mode b is activated; the bit information of the first indication information is 10, which is used to indicate that the monitoring mode c is activated; the bit information of the first indication information is 11, which is used to indicate that the monitoring mode d is activated.

[0261] For another example, the multiple monitoring modes include monitoring mode a and monitoring mode b, the bitmap of the first indication information is 10, which is used to indicate that the monitoring mode a is activated; the bitmap of the first indication information is 01, which is used to indicate that the monitoring mode b is activated. For another example, the multiple monitoring modes include monitoring mode a, monitoring mode b, monitoring mode c and monitoring mode d, the bitmap of the first indication information is 1000, which is used to indicate that the monitoring mode a is activated; the bitmap of the first indication information is 0100, which is used to indicate that the monitoring mode b is activated; the bitmap of the first indication information is 0010, which is used to indicate that the monitoring mode c is activated; the bitmap of the first indication information is 0001, which is used to indicate that the monitoring mode d is activated.

[0262] In another possible mode, the first indication information can indicate the activation of the first monitoring mode in the multiple monitoring modes by a display indication mode, such as by including the identification of the first monitoring mode in the multiple monitoring modes to indicate the activation of the first monitoring mode. The identification of each monitoring mode in the multiple monitoring modes can be configured by the network side device for the terminal side device when the network side device configures the monitoring mode.

[0263] In another possible mode, the first indication information is specifically used to indicate the activation of the first monitoring mode in the multiple monitoring modes in one or more first time periods, or the first indication information is specifically used to indicate the activation of the first monitoring mode in the multiple monitoring modes in part or all of a first time period. In this mode, the first indication information can be indicated by two bitmaps. For example, the first indication information includes a first bitmap and a second bitmap, wherein the first bitmap is used to indicate one or more first time periods, and the second bitmap is used to indicate the first monitoring mode in the multiple monitoring modes.

[0264] For example, the first indication information includes a first bitmap and a second bitmap, the multiple monitoring modes include a monitoring mode a and a monitoring mode b, the first bitmap is 110, and the second bitmap is 10. The first indication information is used to indicate that the monitoring mode a is activated in a first first time period and a second first time period.

[0265] In another possible mode, the first indication information is specifically used to indicate that the first monitoring mode is activated in one or more sleep periods of a DRX cycle, or the first indication information is specifically used to indicate that the first monitoring mode is activated in the sleep periods of one or more DRX cycles. In another possible mode, the first indication information is specifically used to indicate that the first monitoring mode in the multiple monitoring modes is activated in one or more active periods of a monitoring cycle, or the first indication information is specifically used to indicate that the first monitoring mode in the multiple monitoring modes is activated in the active periods of one or more monitoring cycles. In another possible mode, the first indication information is specifically used to indicate that the first monitoring mode in the multiple monitoring modes is activated in one or more active periods of a transmission cycle, or the first indication information is specifically used to indicate that the first monitoring mode in the multiple monitoring modes is activated in the active periods of one or more transmission cycles. In the three possible modes, the indication mode of the first indication information can refer to the implementation of the first indication information being specifically used to indicate that the first monitoring mode in the multiple monitoring modes is activated in one or more first time periods, or the first indication information being specifically used to indicate that the first monitoring mode in the multiple monitoring modes is activated in part or all of a first time period, which will not be described herein again.

[0266] For example, the first indication information includes a first bitmap and a second bitmap, the multiple monitoring modes include a monitoring mode a and a monitoring mode b, the first bitmap is 101, and the second bitmap is 01. The first indication information is used to indicate that the monitoring mode b is activated in the active periods of a first transmission cycle and a third transmission cycle.

[0267] In addition, the first indication information can be carried in a non-low-power consumption signal in the active period of a DRX cycle, or can be carried in a low-power consumption signal in the sleep period or the active period of a DRX cycle, or can be carried in a low-power consumption signal in the active period of a monitoring cycle, or can be carried in a low-power consumption signal in the active period of a transmission cycle. The specific implementation modes can refer to the configuration mode one described above, which will not be described herein again.

[0268] For example, FIG. 16 is a schematic diagram of another first indication information. As shown in FIG. 16, the plurality of monitoring modes configured by the network-side device for the terminal-side device include monitoring mode a, monitoring mode b and monitoring mode c, the monitoring mode a is used to indicate monitoring LP-WUS on the 1st, 3rd and 5th slots in the first time period, the monitoring mode b is used to indicate monitoring LP-WUS on the 1st and 4th slots in the first time period, the monitoring mode c is used to indicate monitoring LP-WUS on the 1st, 4th and 5th slots in the first time period, the first indication information is used to indicate activating the monitoring mode b, and the first indication information is carried in the PDCCH in the active period of the DRX cycle. That is, the network-side device indicates the terminal-side device to activate the monitoring mode b through the first indication information carried in the PDCCH in the active period of the DRX cycle. Therefore, the terminal-side device can activate the monitoring mode b based on the first indication information, and monitor LP-WUS based on the monitoring mode b in the first time period, that is, monitor LP-WUS on the 1st and 4th slots in the first time period.

[0269] In an optional implementation, the network-side device further sends second indication information. Correspondingly, the terminal-side device further receives the second indication information.

[0270] In an optional implementation, the second indication information is used to indicate deactivating / releasing the first monitoring mode, or the second indication information is used to trigger deactivating / releasing the first monitoring mode.

[0271] Optionally, the terminal-side device further deactivates / releases the first monitoring mode based on the second indication information. When the second indication information is used to indicate deactivating / releasing the first monitoring mode, the terminal-side device learns that the first monitoring mode needs to be deactivated / released through the interpretation of the second indication information, and thus deactivates / releases the first monitoring mode. When the second indication information is used to trigger deactivating / releasing the first monitoring mode, it is indicated that the role of the second indication information is to trigger deactivating / releasing the first monitoring mode, and thus the terminal-side device triggers the action of deactivating / releasing the first monitoring mode after receiving the second indication information, so that the terminal-side device deactivates / releases the first monitoring mode. Wherein, the terminal-side device deactivates / releases the first monitoring mode based on the second indication information can be understood as: the terminal-side device does not use the first monitoring mode to monitor LP-WUS in the first time period based on the second indication information.

[0272] In addition, the second indication information can indicate deactivating / releasing the first monitoring mode or be used to trigger deactivating / releasing the first monitoring mode in a variety of ways, and the specific implementation can refer to the above-mentioned implementation of the first indication information indicating activating the first monitoring mode, which will not be described herein again.

[0273] In a possible manner, the second indication information is specifically used to indicate deactivation of the first monitoring mode in one or more first time periods, or the second indication information is specifically used to trigger deactivation of the first monitoring mode in one or more first time periods. This manner is beneficial for the terminal-side device to deactivate the first monitoring mode in one or more first time periods based on the second indication information.

[0274] In another possible manner, the second indication information is specifically used to indicate deactivation of the first monitoring mode in part or all of a first time period, or the second indication information is specifically used to trigger deactivation of the first monitoring mode in part or all of a first time period. This manner is beneficial for the terminal-side device to deactivate the first monitoring mode in part or all of a first time period based on the second indication information.

[0275] In yet another possible manner, the second indication information is specifically used to indicate deactivation of the first monitoring mode in one or more sleep periods of a DRX cycle, or the second indication information is specifically used to trigger deactivation of the first monitoring mode in one or more sleep periods of a DRX cycle. When the second indication information is used to indicate deactivation of the first monitoring mode in one or more sleep periods of a DRX cycle, the terminal-side device also deactivates the first monitoring mode in one or more sleep periods of a DRX cycle based on interpretation of the second indication information. When the second indication information is used to trigger deactivation of the first monitoring mode in one or more sleep periods of a DRX cycle, the terminal-side device triggers deactivation of the first monitoring mode in one or more sleep periods of a DRX cycle after receiving the second indication information, so as to deactivate the first monitoring mode in one or more sleep periods of a DRX cycle.

[0276] In addition, the second indication information can indicate deactivation of the first monitoring mode in one or more sleep periods of a DRX cycle or trigger deactivation of the first monitoring mode in one or more sleep periods of a DRX cycle in various manners, and specific implementation manners can be referred to the implementation manners of the first indication information indicating activation of the first monitoring mode in one or more sleep periods of a DRX cycle described above, which will not be described herein.

[0277] In another possible implementation, the second indication information is specifically used to indicate deactivation of the first monitoring mode in one or more active periods of the monitoring cycle, or the second indication information is specifically used to trigger deactivation of the first monitoring mode in one or more active periods of the monitoring cycle. In this case, the terminal-side device can deactivate the first monitoring mode in one or more active periods of the monitoring cycle based on the second indication information.

[0278] In another possible implementation, the second indication information is specifically used to indicate deactivation of the first monitoring mode in one or more active periods of the monitoring cycle, or the second indication information is specifically used to trigger deactivation of the first monitoring mode in one or more active periods of the monitoring cycle. In this case, the terminal-side device can deactivate the first monitoring mode in one or more active periods of the monitoring cycle based on the second indication information.

[0279] In another possible implementation, the second indication information is specifically used to indicate deactivation of the first monitoring mode in one or more active periods of the monitoring cycle, or the second indication information is specifically used to trigger deactivation of the first monitoring mode in one or more active periods of the monitoring cycle. In this case, the terminal-side device can deactivate the first monitoring mode in one or more active periods of the monitoring cycle based on the second indication information.

[0280] In another possible implementation, the second indication information is specifically used to indicate deactivation of the first monitoring mode in one or more active periods of the monitoring cycle, or the second indication information is specifically used to trigger deactivation of the first monitoring mode in one or more active periods of the monitoring cycle. In this case, the terminal-side device can deactivate the first monitoring mode in one or more active periods of the monitoring cycle based on the second indication information.

[0281] In another possible implementation, the second indication information is specifically used to indicate deactivation of the first monitoring mode in one or more active periods of the monitoring cycle, or the second indication information is specifically used to trigger deactivation of the first monitoring mode in one or more active periods of the monitoring cycle. In this case, the terminal-side device can deactivate the first monitoring mode in one or more active periods of the monitoring cycle based on the second indication information.

[0282] The specific implementation of the second indication information can refer to the corresponding implementation of the first indication information, which will not be described again.

[0283] In another alternative implementation, the network-side device further sends third indication information. Correspondingly, the terminal-side device further receives the third indication information.

[0284] In an alternative implementation, the third indication information is used to instruct switching the first monitoring mode to the second monitoring mode, and the first monitoring mode is different from the second monitoring mode.

[0285] The first monitoring mode and the second monitoring mode are different, and specifically, a MO of monitoring the LP-WUS instructed by the first monitoring mode is different from a MO of monitoring the LP-WUS instructed by the second monitoring mode; or a MO of not monitoring the LP-WUS instructed by the first monitoring mode is different from a MO of not monitoring the LP-WUS instructed by the second monitoring mode; or the MO of monitoring the LP-WUS instructed by the first monitoring mode is the same as a MO of not monitoring the LP-WUS instructed by the second monitoring mode; or the MO of not monitoring the LP-WUS instructed by the first monitoring mode is the same as a MO of monitoring the LP-WUS instructed by the second monitoring mode.

[0286] In addition, the third indication information can instruct switching the first monitoring mode to the second monitoring mode by carrying an identifier of the first monitoring mode and an identifier of the second monitoring mode.

[0287] Alternatively, the terminal-side device deactivates the first monitoring mode and activates the second monitoring mode based on the third indication information. It can be seen that the terminal-side device can further suspend using the first monitoring mode to monitor the LP-WUS and use the second monitoring mode to monitor the LP-WUS in the first time period based on the third indication information.

[0288] In a possible manner, the third indication information is specifically used to instruct switching the first monitoring mode to the second monitoring mode in one or more first time periods, or the third indication information is specifically used to instruct switching the first monitoring mode to the second monitoring mode in part or all of a first time period. In this manner, the terminal-side device further switches the first monitoring mode to the second monitoring mode in one or more first time periods or in part or all of a first time period based on the third indication information.

[0289] Optionally, the third indication information can indicate switching the first monitoring mode to the second monitoring mode in one or more first time periods, or indicate switching the first monitoring mode to the second monitoring mode in part or all of one first time period, by carrying the identifier of the first monitoring mode and the identifier of the second monitoring mode, and further including a bitmap. For example, the third indication information includes the identifier of the first monitoring mode and the identifier of the second monitoring mode, and the third indication information further includes a bitmap of 110, which is used to indicate switching the first monitoring mode to the second monitoring mode in the first first time period and the second first time period. For another example, the third indication information includes the identifier of the first monitoring mode and the identifier of the second monitoring mode, and the third indication information further includes a bitmap of 101, which is used to indicate switching the first monitoring mode to the second monitoring mode in the first first time period and the third first time period.

[0290] In another possible manner, the third indication information is specifically used to indicate switching the first monitoring mode to the second monitoring mode in one or more sleep periods of a DRX cycle. In this manner, the terminal-side device further switches the first monitoring mode to the second monitoring mode, or deactivates the first monitoring mode and activates the second monitoring mode, in the one or more sleep periods of the DRX cycle based on the third indication information.

[0291] In another possible manner, the third indication information is specifically used to indicate switching the first monitoring mode to the second monitoring mode in one or more sleep periods of a DRX cycle. In this manner, the terminal-side device further switches the first monitoring mode to the second monitoring mode, or deactivates the first monitoring mode and activates the second monitoring mode, in the one or more sleep periods of the DRX cycle based on the third indication information.

[0292] In another possible manner, the third indication information is specifically used to indicate switching the first monitoring mode to the second monitoring mode in one or more active periods of a monitoring cycle, or the third indication information is specifically used to indicate switching the first monitoring mode to the second monitoring mode in one or more active periods of one or more monitoring cycles. In this manner, the terminal-side device can switch the first monitoring mode to the second monitoring mode in one or more active periods of a monitoring cycle, or in one or more active periods of one or more monitoring cycles, based on the third indication information.

[0293] In another possible manner, the third indication information is specifically used to indicate switching the first monitoring mode to the second monitoring mode in one or more active periods of a transmission period, or the third indication information is specifically used to indicate switching the first monitoring mode to the second monitoring mode in an active period of one or more transmission periods. In this manner, the terminal-side device can switch the first monitoring mode to the second monitoring mode in one or more active periods of a transmission period, or in an active period of one or more transmission periods, based on the third indication information.

[0294] In the above four indication manners of the third indication information, the implementation of the third indication information can refer to the implementation of the third indication information being specifically used to indicate switching the first monitoring mode to the second monitoring mode in one or more first time periods, or being specifically used to indicate switching the first monitoring mode to the second monitoring mode in part or all of a first time period, which will not be repeated. For example, the third indication information includes the identifier of the first monitoring mode and the identifier of the second monitoring mode, and the third indication information further includes a bitmap of 011, and the third indication information is used to indicate switching the first monitoring mode to the second monitoring mode in the active period of the second transmission period and the third transmission period.

[0295] In a possible manner, the second indication information or the third indication information is carried in a low-power consumption signal, such as a low-power consumption signal in a sleep period of a DRX period, such as a low-power consumption signal in an active period of a DRX period, such as a low-power consumption signal in an active period of a monitoring period, such as a low-power consumption signal in an active period of a transmission period. This manner can reduce energy consumption.

[0296] In an optional implementation, the MO for monitoring the LP-WUS is located in a timing period of a first timer, and the timing period of the first timer is located in part or all of the active period of the DRX period.

[0297] The first timer is one or more of the following: a duration timer (drx-onDurationTimer), an inactivity timer (drx-InactivityTimer), a retransmission timer (drx-RetransmissionTimer), and a contention resolution timer (ra-contention resolution timer). The drx-RetransmissionTimer includes a drx-RetransmissionTimerDL and a drx-RetransmissionTimerUL.

[0298] When the first timer is drx-InactivityTimer, the terminal-side device still needs to monitor the LP-WUS even if the originally configured drx-onDurationTimer has ended, so that the PDCCH can be monitored based on the monitored LP-WUS.

[0299] When the first timer is drx-RetransmissionTimer, it indicates that the terminal-side device needs to monitor the LP-WUS when the drx-RetransmissionTimer is running, so that the PDCCH for hybrid automatic repeat request (HARQ) retransmission can be monitored based on the monitored LP-WUS.

[0300] When the first timer is ra-contention resolution timer, the terminal-side device starts the ra-contention resolution timer after sending the msg3, and monitors the LP-WUS before the timer expires or stops.

[0301] Optionally, the first timer can also be a timer that is running when msgB-ResponseWindow is running. In this way, the terminal-side device starts the timer after sending the preamble, and monitors the LP-WUS before the timer expires or stops.

[0302] That is, the terminal-side device can monitor the LP-WUS during the timing period of the first timer in part or all of the active period of the DRX cycle, so that the PDCCH can be monitored based on the monitored LP-WUS. Compared with the terminal-side device continuously monitoring the PDCCH during the active period of the DRX cycle, this way reduces the number of times the PDCCH is monitored, or in other words, reduces the complexity of monitoring the PDCCH, and can reduce the power consumption of the terminal-side device.

[0303] In an optional implementation, the terminal-side device stops monitoring the LP-WUS when the first condition is met. The first condition includes at least one of the following: drx-ShortCycleTimer expires, and the first timer stops running. When the drx-ShortCycleTimer expires, it indicates that the LP-WUS or PDCCH has not been monitored for multiple time slots in the short cycle, and the long cycle is entered, so that the terminal-side device stops monitoring the LP-WUS.

[0304] It can be seen that in the embodiment of the application, the terminal-side device can monitor the LP-WUS in part or all of the sleep period of the DRX cycle based on the first monitoring mode, so as to facilitate the terminal-side device to flexibly monitor the PDCCH based on the monitored LP-WUS, reduce the probability of missing data in the sleep period of the DRX cycle while reducing the power consumption of the terminal-side device, and improve the user experience.

[0305] The embodiment of the application also proposes an exemplary low-power wake-up signal monitoring method based on the low-power wake-up signal monitoring method shown in FIG. 9, taking the case that the network-side device instructs the terminal-side device to activate the configured monitoring mode by indication information. The method is shown in FIG. 17, and the interaction process includes but is not limited to the following steps:

[0306] S1701. The network-side device sends first configuration information to the terminal-side device, and the first configuration information is used to configure the first monitoring mode, or the first configuration information is used to configure multiple monitoring modes, and the multiple monitoring modes include the first monitoring mode. Correspondingly, the terminal-side device receives the first configuration information from the terminal-side device.

[0307] S1702. The network-side device sends first indication information to the terminal-side device, and the first indication information is used to instruct to activate the first monitoring mode. Correspondingly, the terminal-side device receives the first indication information from the network-side device.

[0308] S1703. The terminal-side device monitors the LP-WUS in the first time period based on the first monitoring mode.

[0309] The related descriptions in S1701 to S1703 can be referred to the related descriptions in FIG. 9, and will not be repeated.

[0310] It can be seen that the network-side device configures the first monitoring mode for the terminal-side device through the first configuration information, and instructs the terminal-side device to activate the first monitoring mode through the first indication information, so that the terminal-side device can monitor the LP-WUS in the first time period based on the first monitoring mode. The first time period includes part or all of the sleep period of the DRX cycle, so the terminal-side device can monitor the LP-WUS in part or all of the sleep period of the DRX cycle based on the first monitoring mode, and then can monitor the PDCCH based on the monitored LP-WUS, reduce the probability of missing data in the sleep period of the DRX cycle while reducing the power consumption of the terminal-side device, and improve the user experience.
