Description

Wake-up method and apparatus

[0001] The present application claims priority to the Chinese patent application No. 202410891260.6, filed on July 3, 2024, entitled “Wake-up method and apparatus”, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

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

[0003] In a user centric and no cell (UCNC) scenario, in order to guarantee service continuity of a terminal, multiple transmission and receive points (TRPs) are usually turned on at the same time to provide services for the terminal, for example, uplink coordinated communication or downlink coordinated communication. For example, in uplink coordinated communication, the terminal can send the same data to two TRPs, and the TRPs can have a combining gain after exchanging data between them. For another example, in downlink coordinated communication, one TRP can send two streams of data to the terminal, and another TRP can send another two streams of data to the terminal, and the terminal actually receives four streams of data, etc.

[0004] In an anchor base station (Anchor BS) scenario, the Anchor BS provides coverage services, and the Anchor BS can also be referred to as a super base station, which generally works in a low frequency band and guarantees that all users can access the network. The Anchor BS can be a satellite or a high-altitude balloon, and for a ground station, the Anchor BS is generally several hundred meters high. For hot spot areas, a small station or a macro station usually provides capacity services.

[0005] In a scenario combining UCNC and Anchor BS, the Anchor BS can provide coverage services for users, the Anchor BS can manage one or more TRPs, each TRP provides uplink and downlink data transmission services for a terminal, and the TRP can enter a sleep state after completing data transmission. Nowadays, when the Anchor BS wants to wake up the sleeping TRP to provide services for the terminal, it needs to first exchange messages through an inter-base station communication interface, wake up the TRP, and then the TRP wakes up the terminal through a wake-up signal. The Anchor BS wakes up the terminal and the TRP in this way, which has large overall latency and large signaling overhead. SUMMARY

Of course, with the development of standards, other types of entities may also appear in the future, which are not limited in the embodiments of the present application.

[0055] FIG. 1 is a schematic diagram of an architecture of a communication system according to an embodiment of the present application. As shown in FIG. 1, the communication system can include at least one network device and at least one terminal device, such as terminal device 1 to terminal device 4 in FIG. 1. The terminal device and the network device can communicate with each other through an air interface Uu link or an NTN link, etc. For example, terminal device 3 and terminal device 4 can communicate with each other through a D2D sidelink, etc. The form of the terminal device shown in FIG. 2 is only an example. In a specific implementation, the terminal device can also include a vehicle-mounted device or a vehicle-mounted terminal in a vehicle network, etc. The embodiments of the present application do not limit the specific form of the terminal device when it is applied to a vehicle network or the Internet.

[0056] FIG. 2 is a schematic diagram of an architecture of a communication system according to an embodiment of the present application. Taking a base station as an example, the present application can be applied to a scenario where a super base station (super BS) and a ground base station exist at the same time. The super base station can also be referred to as an anchor base station (anchor BS).

[0057] The super base station can be a satellite, a high altitude platform station (HAPS), an air balloon station, a drone station, a broadcast station, etc. The super base station and the ground base station can be connected through an optical fiber or wireless transmission. The ground base station can be a cellular station in the communication system, such as a macro station, a small station, a micro station, etc. or other implementation manners. The super base station has the functions of providing network services for terminal devices and managing and controlling base stations, such as waking up or shutting down a certain ground base station. The terminal devices in the network area covered by the super base station can access the super base station to obtain network services through the super base station, or can access the ground base station under the super base station. Generally, the super base station provides network coverage services for terminal devices, and the ground base station provides capacity services for terminal devices. Therefore, the signal coverage area of the super base station is generally larger than that of the ground base station, and the signal coverage area of the super base station and the signal coverage area of the ground base station have an intersection.

[0058] The terminal device and the network device are described in detail below.

[0059] A terminal device is a device with wireless transceiver function, which is referred to as terminal below. The terminal can communicate with an access network device (or also referred to as access device or network device shown below) in a radio access network (RAN). The terminal can also be referred to as user equipment (UE), access terminal, terminal, subscriber unit, subscriber station, mobile station, remote station, remote terminal, mobile device, user terminal, user agent, or user device, etc. In a possible implementation, the terminal can be deployed on land, including indoor or outdoor, handheld or vehicle-mounted; or can be deployed on water, including a ship; or can be deployed in the air, such as an airplane, balloon or satellite, etc. In another possible implementation, the terminal can be a handheld device, vehicle-mounted device, wearable device, sensor, terminal in Internet of Things, terminal in Internet of Vehicles, unmanned aerial vehicle, terminal in 5G network or future network with wireless communication function, etc. The embodiments of the present application do not limit this. In yet another possible implementation, the terminal can also be a virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in unmanned driving, wireless terminal in remote medical treatment, wireless terminal in smart power grid, wireless terminal in smart city, or wireless terminal in smart home, etc.

[0060] In the embodiments of the present application, the apparatus for implementing the function of the terminal can be a terminal; or can be an apparatus capable of supporting the terminal to implement the function, such as a chip system. The apparatus can be installed in the terminal or used in matching with the terminal. In the embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices. For ease of description, the apparatus for implementing the function of the terminal is taken as an example of UE to describe the technical solutions provided by the embodiments of the present application.

[0061] The network device can be a device deployed in a wireless access network to provide wireless communication services for terminals. The network device can also be referred to as an access network device, an access device, or a RAN device, etc. An exemplary network device can be a super base station or a ground base station shown in FIG. 2. As another example, the network device can be a next generation node B (gNB), a next generation evolved node B (ng-eNB), or a network device in 6G communication, etc. The network device can be any device with wireless transceiver function, including but not limited to the base stations shown above (including base stations deployed on satellites). The network device can also be a device with base station function in 6G. As an example, the network device can be an access node, a wireless relay node, a wireless backhaul node, etc. in a wireless fidelity (Wi-Fi) system. As another example, the network device can be a wireless controller in a cloud radio access network (CRAN) scenario. As yet another example, the network device can be a wearable device or a vehicle-mounted device, etc. that can provide wireless communication services. As yet another example, the network device can also be a small station, a transmission reception point (TRP) (or also referred to as a transmission point), etc. In systems of different wireless access technologies, the names of devices with network device functions can be different, and the embodiments of the present application will not be listed one by one.

[0062] The network device can be fixed or mobile. For example, a helicopter or a drone can be configured to act as a mobile network device, and one or more cells can move according to the location of the mobile network device. In other examples, the helicopter or the drone can be configured to act as a device that communicates with another network device.

[0063] In some deployments of a network device, the network device can include a centralized unit (CU) and a distributed unit (DU), etc. For example, part of the protocol layers of the network device are controlled by the CU, and the rest or all of the protocol layers are distributed in the DU and controlled by the CU. In some other deployments of the network device, the CU can also be divided into a CU-control plane (CP) and a CU-user plane (UP), etc. In some other deployments of the network device, the network device can also be an open radio access network (ORAN) architecture. When the network device is an ORAN architecture, the network device can be a functional entity or a module in the ORAN, etc. For example, the network device can be a combination of one or more of a CU, a DU, or a RU. In the ORAN system, the CU can also be referred to as an open (O)-CU, the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, etc. The deployment manners of the network device listed herein are only examples, and as the standard technology evolves, there can be other deployment forms of the network device, which are not limited by the embodiments of the present application.

[0064] In some deployments, a plurality of RAN nodes cooperate to assist a terminal to implement wireless access, and different RAN nodes implement part of the functions of the access network, respectively. For example, the RAN node can be a CU, a DU, a CU-CP, a CU-UP, or a RU, etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a building base band unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0065] The RAN node can support one or more types of fronthaul interfaces, different fronthaul interfaces respectively corresponding to DUs and RUs having different functions. If the fronthaul interface between the DU and the RU is a common public radio interface (CPRI), the DU is configured to implement one or more of baseband functions, and the RU is configured to implement one or more of radio frequency functions. If the fronthaul interface between the DU and the RU is another interface, relative to the CPRI, part of the baseband functions of the downlink and / or uplink, such as, for the downlink, one or more of precoding, digital beamforming (BF), or inverse fast Fourier transform (IFFT) / add cyclic prefix (CP), are moved from the DU to the RU for implementation, and for the uplink, one or more of digital beamforming (BF), or fast Fourier transform (FFT) / remove cyclic prefix (CP), are moved from the DU to the RU for implementation. In a possible implementation, the interface can be an enhanced common public radio interface (eCPRI). Under the eCPRI architecture, the splitting manner between the DU and the RU is different, corresponding to different categories (Cat) of eCPRI, such as eCPRI Cat A, B, C, D, E, F.

[0066] Taking eCPRI Cat A as an example, for downlink transmission, with layer mapping as the cut, the DU is configured to implement layer mapping and one or more functions (i.e., one or more of encoding, rate matching, scrambling, modulation, layer mapping) before layer mapping, and other functions (e.g., one or more of resource element (RE) mapping, digital beamforming (BF), or IFFT / add CP) after layer mapping are implemented in the RU. For uplink transmission, with de-RE mapping as the cut, the DU is configured to implement de-mapping and one or more functions (i.e., one or more of decoding, de-rate matching, de-scrambling, de-modulation, inverse discrete Fourier transform (IDFT), channel equalization, de-RE mapping) before de-mapping, and other functions (e.g., one or more of digital BF or FFT / CP removal) after de-mapping are implemented in the RU. It can be understood that the function description of the DU and the RU corresponding to various types of eCPRI can refer to the eCPRI protocol, and will not be described here.

[0067] In a possible design, the processing unit in the BBU for implementing baseband functions is referred to as a base band high (BBH) unit, and the processing unit in the RRU / AAU / RRH for implementing baseband functions is referred to as a base band low (BBL) unit.

[0068] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. Any of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0069] The network device and / or the terminal can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water surface; and can also be deployed on airplanes, balloons and satellites in the air. The scenarios in which the network device and the terminal are located are not limited in the embodiments of the present application. In addition, the terminal and the network device can be hardware devices, or software functions running on special hardware, software functions running on general hardware, such as virtualized functions instantiated on a platform (for example, a cloud platform), or entities including special or general hardware devices and software functions. The specific forms of the terminal and the network device are not limited in the present application.

[0070] In the embodiments of the present application, the apparatus for implementing the function of the network device can be a network device, or an apparatus capable of supporting the network device to implement the function, such as a chip system. The apparatus can be installed in the network device or used in matching with the network device. For ease of description, the apparatus for implementing the function of the network device is taken as a base station to describe the technical solutions provided in the embodiments of the present application when some specific examples are involved.

[0071] In a user-centric and no cell (UCNC) scenario, in order to ensure the service continuity of the terminal, multiple TRPs are usually started at the same time to provide services for the terminal, for example, uplink coordinated communication or downlink coordinated communication. The uplink coordinated communication means that the terminal sends the same data to two TRPs, and the TRPs can have a combination gain after communicating and exchanging data between them. The downlink coordination means that one TRP sends two streams of data, and another TRP sends another two streams of data, and the terminal actually receives four streams of data. In the Anchor BS scenario, the Anchor BS provides coverage services. For hot spot areas, small stations / macrostations usually provide capacity services.

[0072] In the scenario of combination of UCNC and Anchor BS, the Anchor BS can provide coverage services for users. The Anchor BS can manage one or more TRPs, and each TRP provides uplink and downlink data transmission services for the terminal. After the TRP completes the data transmission, it can enter a sleep state. Now, the Anchor BS wants to wake up the sleeping TRP to provide services for the terminal. It is necessary to first perform message interaction through the communication interface between base stations, wake up the TRP, and then the TRP wakes up the terminal through a wake-up signal. The Anchor BS wakes up the terminal and the TRP in this way, and the whole process has large latency and large signaling overhead.

[0073] In order to save signaling, an embodiment of the present application proposes a wake-up method, as shown in FIG. 3, which includes step 301. The method shown in FIG. 3 corresponds to the execution subject of the first terminal, the first network device and the second network device, or the method execution subject shown in FIG. 3 can be the chip in the first terminal, the chip in the first network device and the chip in the second network device. FIG. 3 takes the first terminal, the first network device and the second network device as an example for illustration. The execution subject of the wake-up method is not limited in the embodiments of the present application. The first terminal can be the terminal device described above, the first network device and the second network device can be the network devices in the communication system shown in FIG. 1, or the first network device can be the super base station in the communication system shown in FIG. 2, and the second network device can be the ground base station shown in FIG. 2. Wherein:

[0074] 301. The first network device sends a first signal, which is used to wake up the devices in the first subgroup, the first subgroup including at least one network device and at least one terminal.

[0075] In the embodiments of the present application, the first network device can manage at least one network device, for example, the second network device is one of the network devices managed by the first network device, and the first network device can wake up or shut down the second network device. The first network device has the function of providing network service for the terminal, and the terminal located in the coverage area of the first network device can access the first network device, or can also access the network device managed by the first network device, for example, the second network device.

[0076] The plurality of network devices and the plurality of terminals managed by the first network device are divided to obtain a plurality of subgroups, each terminal in the plurality of terminals belongs to one subgroup in the plurality of subgroups, each network device in the plurality of network devices belongs to at least one subgroup in the plurality of subgroups, and each subgroup in the plurality of subgroups includes at least one network device and at least one terminal. The network device in a subgroup can provide uplink and downlink services for the terminals in the subgroup to which it belongs. Wherein, a network device can only belong to one subgroup, or can belong to multiple subgroups.

[0077] For example, as shown in FIG. 4, the network devices managed by the first network device include network device 1 to network device 4, and the terminals located in the coverage area of the first network device include terminal 1 to terminal 6. Dividing the four network devices and six terminals can obtain that subgroup 1 includes network device 1, terminal 1 and terminal 2, subgroup 2 includes network device 2 and terminal 3, and subgroup 3 includes network device 3, network device 4, terminal 4, terminal 5 and terminal 6.

[0078] Correspondingly, the second network device receives the first signal.

[0079] In some examples, the first signal is used to wake up the device in the first group, i.e. the target device that the first network device wants to wake up is the device in the first group, and the second network device can determine whether it is the target device that the first network device wants to wake up according to one of the following two manners.

[0080] (1) The first signal carries the identifier of the first group, and the second network device can determine whether it belongs to the first group, i.e. whether it is the target device that the network device wants to wake up, according to whether the identifier of the first group carried by the first signal is the same as the identifier of the group to which the second network device belongs. Optionally, in this case, the first network device can send the first signal in a broadcast manner.

[0081] If the second network device belongs to the first group, i.e. the identifier of the group to which the second network device belongs is the same as the identifier of the first group, the second network device switches from the sleep state to the wake-up state after receiving the first signal; if the second network device does not belong to the first group, i.e. the identifier of the group to which the second network device belongs is not the same as the identifier of the first group, the second network device can continue to be in the sleep state to save energy consumption.

[0082] (2) The first network device can send the first signal to at least one network device in the first group through unicast or groupcast, or an interface between network devices (an interface between base stations). It can be understood that in this scenario, the network devices (such as the second network device) that receive the first signal by default are the target devices that need to be woken up, i.e. the network devices that receive the first signal belong to the first group. The second network device receives the first signal by default, and determines that it is the target device that the network device needs to wake up, and switches from the sleep state to the wake-up state. Optionally, in this case, the first signal can not need to carry the identifier of the first group.

[0083] The sleep state can also be referred to as a sleep mode, a sleep state, a sleep mode, an energy-saving state, or an energy-saving mode. The second network device in the sleep state will no longer perform data transmission with the terminal, thereby saving power consumption. The second network device in the sleep state can monitor or detect the first signal. The wake-up state can also be referred to as a wake-up mode, an active state, an active mode, a normal state, or a normal mode. The second network device in the wake-up state can perform data transmission with the terminal.

[0084] Optionally, the first signal can be a wake up signal (WUS) or a low power wake-up signal (LP-WUS). Further optionally, when the first signal is an LP-WUS, the second network device in the sleep state means that a main radio (MR) of the second network device is in the sleep state or is powered off, and the second network device turns on a low-power radio (LR) to monitor the LP-WUS. The second network device in the wake-up state means that the MR of the second network device is in the wake-up state or is powered on.

[0085] The MR can be used to receive downlink signaling, signals, and data, and the like. The MR can be referred to as a main receiver, a main communication module, or a main circuit, and the like. The MR includes a medium radio frequency module and a baseband processing module. The LR is used to monitor the LP-WUS. The LR can also be referred to as a wake-up receiver, a low-power wake-up radio (LP-WUR) receiver, a wake-up circuit, an auxiliary communication module, or an auxiliary circuit, and the like. The LR includes a simple receiver composed of a medium radio frequency module. The working power consumption of the LR is much lower than that of the MR. When there is no MR data to be transmitted for a period of time, the MR can enter the sleep state or be powered off. At this time, the LR is in the powered-on state and monitors the LP-WUS. After the LR receives the LP-WUS and determines that it is a target device that needs to be woken up, the LR triggers the MR to wake up or be powered on, and then the MR starts data transmission.

[0086] Correspondingly, the first terminal receives the first signal.

[0087] In some examples, the first signal is used to wake up the devices in the first group, i.e., the target device that the first network device wants to wake up through the first signal is the device in the first group. The first terminal can determine whether it is the target device that the first network device needs to wake up according to one of the following two ways.

[0088] (1) The first signal carries an identifier of the first group. The first terminal can determine whether it belongs to the first group, i.e., whether it is the target device that the network device needs to wake up, according to whether the identifier of the first group carried by the first signal is the same as the identifier of the group to which the first terminal belongs. Optionally, in this case, the first network device can send the first signal in a broadcast manner.

[0089] If the first terminal belongs to the first group, i.e., the identity of the group to which the first terminal belongs is the same as the identity of the first group, the first terminal switches from the sleep state to the wake-up state after receiving the first signal; if the first terminal does not belong to the first group, i.e., the identity of the group to which the first terminal belongs is not the same as the identity of the first group, the first terminal can continue to be in the sleep state to save energy.

[0090] (2) The first terminal switches from the sleep state to the wake-up state after receiving the first signal from the first network device. Then, the first terminal acquires scheduling information from the second network device through PDCCH blind detection, the scheduling information indicating the first resource, and finally the first terminal receives the first information from the second network device on the first resource, the first information indicating the identity of the first group.

[0091] It can be understood that after the second network device is woken up by the first network device through the first signal, the second network device can send scheduling information on the PDCCH, the scheduling information indicating the first resource, and the second network device sends the first information on the first resource, the first information indicating the identity of the first group. After receiving the first information, the first terminal determines whether it belongs to the first group, i.e., whether it is the target device that the network device needs to wake up, according to whether the identity of the first group carried by the first signal is the same as the identity of the group to which it belongs.

[0092] Optionally, the first terminal performs blind detection through a preset aggregation level, and correspondingly, the second network device can send the scheduling information through the preset aggregation level. The preset aggregation level includes at least one aggregation level. The preset aggregation level can be predefined, configured by the second network device or the first network device, or determined through negotiation between the first terminal and the second network device. The aggregation level can also be referred to as an aggregation grade. The aggregation level represents the number of CCEs (Control-channel element) that constitute the PDCCH. That is, a PDCCH is composed of L CCEs, and the aggregation level of the PDCCH is L, L being an integer greater than or equal to 1. In this way, it is beneficial to reduce the number of blind detections of the first terminal.

[0093] If the first terminal belongs to the first group, i.e., the identity of the group to which the first terminal belongs is the same as the identity of the first group, the first terminal will continue to be in the wake-up state; if the first terminal does not belong to the first group, i.e., the identity of the group to which the first terminal belongs is not the same as the identity of the first group, the first terminal will switch from the wake-up state to the sleep state to save energy.

[0094] The first terminal in the dormant state will no longer perform one or more of the following operations: data transmission, detection of a synchronization signal / physical broadcast channel block (SSB), acquisition of system information, or monitoring of a paging message, so as to save energy consumption. The first terminal in the wake-up state will perform one or more of the following operations: data transmission, detection of an SSB, acquisition of system information, or monitoring of a paging message.

[0095] Optionally, the first signal can be a WUS or an LP-WUS. Further optionally, when the first signal is an LP-WUS, the first terminal in the dormant state means that the MR of the first terminal is in the dormant state or the MR is powered off, and the first terminal starts to monitor the first signal in the LR. The first terminal in the wake-up state means that the MR of the first terminal is in the wake-up state or the MR is powered on.

[0096] Based on the method described in the embodiments of the present application, the first network device only sends the first signal, so as to wake up the second network device and the first terminal at the same time, which is beneficial to shorten the latency of waking up the first terminal and the second network device, and is beneficial to save signaling overhead.

[0097] In a possible implementation, the identifier of the first group can be predefined, or configured by the first network device or the second network device, or determined through information interaction between the first terminal and the second network device or the first network device.

[0098] When the identifier of the first group is configured by the first network device or the second network device, it can be divided into dynamic configuration and static configuration.

[0099] For example, the identifier of the first group is configured by the second network device, and the specific implementation is that the second network device sends first configuration information, the first configuration information indicating the identifier of the first group, or the first configuration information indicating a first parameter used to determine the identifier of the first group, and correspondingly, the first terminal receives the first configuration information. Optionally, the first parameter can be a terminal identifier (UE ID), an identifier of the second network device (TRP ID), or a cell identifier (cell ID). When the first configuration information indicates the first parameter used to determine the identifier of the first group, the first terminal can calculate the identifier of the first group according to the first parameter.

[0100] The following describes two ways of dynamically configuring the identity of the first group and statically configuring the identity of the first group, taking the first configuration information indicating the identity of the first group as an example. When the first configuration information indicates the first parameter used to determine the identity of the first group, the following described dynamic configuration or static configuration is also applicable.

[0101] (1) Dynamic configuration: the first configuration information is carried in a low power synchronization signal (LP-SS). The second network device sends the LP-SS through the LR, and the LP-SS carries the first configuration information. When the second network device sends the LP-SS, the second network device can be in a sleep state. Correspondingly, the first terminal can be in a sleep state, and the first terminal in the sleep state can detect the LP-SS. Optionally, the first terminal can periodically detect the LP-SS.

[0102] Optionally, the LP-SSs sent at different time domain positions carry different group identities. Further optionally, the different time domain positions can refer to different time units, which can refer to a symbol, a slot, or a radio subframe, etc.

[0103] For example, when a network device belongs to multiple groups, the network device can send LP-SSs at different time domain positions to indicate the different groups to which it belongs. Taking the second network device belonging to the first group and the second group as an example, the second network device can send the first configuration information at the first time domain position, and the first configuration information indicates the identity of the first group. The second network device can send the second configuration information at the second time domain position, and the second configuration information indicates the identity of the second group. The first configuration information and the second configuration information are both carried on the LP-SS. Correspondingly, the terminal receiving the first configuration information from the first network device belongs to the first group, and the terminal receiving the second configuration information from the second network device belongs to the second group.

[0104] For another example, when two different network devices belong to different groups respectively, the two network devices can send LP-SSs at different time domain positions. Taking the network devices managed by the first network device including the second network device and the third network device as an example, the second network device belongs to the first group, and the third network device belongs to the second group. The second network device can send the first configuration information at the first time domain position, and the first configuration information indicates the identity of the first group. The third network device can send the second configuration information at the second time domain position, and the second configuration information indicates the identity of the second group.

[0105] Optionally, the LP-SS and the first signal can have an association relationship or a binding relationship, and the first terminal can determine the position of detecting the first signal according to the association relationship or the binding relationship between the LP-SS and the first signal.

[0106] For example, the Nth first signal sent by the first network device after the LP-SS received by the first terminal is associated with the LP-SS, and the N first signals are wake-up signals for waking up the devices of the first group, where N is a positive integer. For another example, the LP-SS received by the first terminal corresponds to a time window, and the first network device sends the first signal associated with the LP-SS in the time window. The time window can be predefined, or pre-configured, or the LP-SS carries indication information indicating a time window, and the first terminal can detect the first signal in the time window. For another example, the first signal sent by the first network device after the LP-SS received by the first terminal is associated with the LP-SS, and the first signal is a WUS signal. After receiving the LP-SS, the first terminal directly wakes up the MR to receive the first signal, and then determines whether it is the target device of the first network device through subsequent steps such as PDCCH blind detection.

[0107] Further optionally, the second network device can also send the first configuration information to the first network device to indicate that the second network device belongs to the first group.

[0108] (2) Static configuration: the first configuration information is carried in high layer signaling or radio resource control (RRC) signaling. The second network device sends high layer signaling or RRC signaling carrying the first configuration information, and correspondingly, the first terminal receives the high layer signaling or RRC signaling carrying the first configuration information.

[0109] Optionally, the second network device can determine the group to which the terminal belongs according to the area where the terminal is located. The location of the area where the terminal is located can be determined according to a global positioning system (GPS), a radio frequency map (Rfmap), or a positioning algorithm.

[0110] It should be further pointed out that the method of the second network device described above for configuring the identifier of the first group can also be applied to the first network device for configuring the identifier of the first group, which will not be repeated here.

[0111] In a possible implementation, the first terminal moves from the coverage of one network device to the coverage of another network device, taking the first terminal moving from the coverage of a third network device to the coverage of a second network device as an example, wherein the second network device and the third network device are network devices managed by the first network device, the third network device and the second network device do not belong to the same group, the second network device belongs to a first group, and the third network device belongs to a second group. Correspondingly, the first terminal can receive first configuration information from the second network device and second configuration information from the third network device, wherein the first configuration information indicates an identifier of the first group or indicates a first parameter used to determine the identifier of the first group, and the second configuration information indicates an identifier of the second group or indicates a first parameter used to determine the identifier of the second group.

[0112] The third network device and the second network device can belong to the same cell, or can belong to different cells respectively. Optionally, the cell can refer to a user centric and no cell (UCNC). The following describes the group to which the first terminal belongs in two scenarios: the third network device and the second network device belong to the same cell, and the third network device and the second network device belong to different cells respectively.

[0113] (1) The third network device and the second network device do not belong to the same cell:

[0114] When the first terminal moves from the coverage of the third network device to the coverage of the second network device, the first terminal triggers cell switching, and after the cell switching is completed, the second network device provides uplink and downlink services for the first terminal. Therefore, the first terminal can send cell switching information to the third network device in the cell switching process, the cell switching information being used to indicate that the first terminal switches to the cell to which the second network device belongs, and the first terminal belongs to the first group, that is, the first terminal switches from the second group to which the third network device belongs to the first group to which the second network device belongs. Optionally, the cell switching information indicates the identifier of the second network device and / or the location to which the first terminal moves.

[0115] Optionally, the second network device and / or the third network device sends first indication information to the first network device, the first indication information indicating that the first terminal belongs to the first group.

[0116] (2) The third network device and the second network device belong to the same cell:

[0117] Option 1, when the first terminal moves from the coverage of the third network device to the coverage of the second network device, the first terminal can measure the LP-SSs transmitted by the third network device and the second network device, so as to determine whether the position of the first terminal moves from the coverage of the third network device to the coverage of the second network device.

[0118] The specific implementation method includes the following steps:

[0119] Step 1, the first terminal detects the first LP-SS from the second network device and the second LP-SS from the third network device, to obtain a first reference signal received power (RSRP) and a second RSRP, the first RSRP is obtained by signal measurement on the first LP-SS, and the second RSRP is obtained by signal measurement on the second LP-SS.

[0120] Step 2, if the condition that the first RSRP is greater than a first threshold and / or the second RSRP is less than a second threshold is met, the first terminal sends first indication information to the second network device and / or the third network device, the first indication information indicating that the first terminal belongs to the first group.

[0121] It can be understood that, in the case of meeting the condition, it indicates that the first terminal has moved to the coverage of the second network device, so the first terminal can join the first group in which the second network device is located, and if the condition is not met, it indicates that the first terminal is still in the coverage of the third network device, so the first terminal can continue to be in the second group in which the third network device is located.

[0122] Further optionally, after the second network device and / or the third network device receives the first indication information, the second network device and / or the third network device can send second indication information to the first network device, the second indication information indicating that the first terminal belongs to the first group.

[0123] Option 2, when the first terminal moves from the coverage of the third network device to the coverage of the second network device, the first terminal can send an uplink signal, and the third network device and the second network device can measure the uplink signal sent by the first terminal to determine whether the position of the first terminal has moved.

[0124] The specific implementation method includes the following steps:

[0125] Step 1, the first terminal sends an uplink signal. Optionally, the uplink signal is an uplink WUS. The first terminal can periodically send the uplink signal.

[0126] Step 2, the second network device measures the uplink signal sent by the first terminal to obtain a third RSRP, and the third network device measures the uplink signal sent by the first network device to obtain a fourth RSRP.

[0127] Step 3, the second network device and the third network device can interact the measurement results, taking the third network device sending third indication information to the second network device as an example. Correspondingly, the second network device receives the third indication information from the third network device, and the third indication information indicates the fourth RSRP.

[0128] Step 4, if the third RSRP is greater than the fourth RSRP, the second network device sends fourth indication information to the first network device and the first terminal, and the fourth indication information indicates that the first terminal belongs to the first group.

[0129] It can be understood that, in the case that the third RSRP is greater than the fourth RSRP, it indicates that the first terminal has moved to the coverage of the second network device, and therefore the first terminal can join the first group in which the second network device is located. If the third RSRP is less than or equal to the fourth RSRP, it indicates that the first terminal is still in the coverage of the third network device, and therefore the first terminal can continue to be in the second group in which the third network device is located.
