Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0002] In order to reduce the power consumption of user equipment (UE), the UE can use a separate low-power small circuit to receive signals. The low-power small circuit can be implemented using a circuit or chip with a relatively simple structure, and its power consumption is relatively low. The low-power small circuit can be called a wake-up radio (WUR). Among them, the WUR can be used to receive a low-power wake-up signal (LP-WUS) from a network device, and the wake-up indication information can be demodulated according to the information bits carried by the LP-WUS, thereby waking up the main circuit (MR) that is turned off (or in sleep state) in the terminal device.

[0003] After the introduction of WUR, when UE monitoring LP-WUS is activated, the UE can monitor LP-WUS in the WUR. However, for network devices including centralized units (CU) and / or distributed units (DU), how to activate UE monitoring LP-WUS remains to be studied. Summary of the Invention

[0004] The embodiments of the present application provide a communication method and apparatus for activating UE monitoring of LP-WUS under a CU-DU architecture.

[0005] In a first aspect, a first communication method is provided, which is applied to a centralized unit side, that is, the method can be executed by the centralized unit, or by a larger device including the centralized unit, or by a chip system or other functional module, which can implement the functions of the centralized unit, and the chip system or functional module is, for example, arranged in the centralized unit. The centralized unit is, for example, a functional unit included in a network device, which may also be called a base station centralized unit, or may have other names. For example, the centralized unit is a CU. The network device includes, for example, an access network device, such as a base station. The method includes: sending a first indication message or a second indication message to a distributed unit, the first indication message being used to instruct the distributed unit to activate a terminal device to listen to LP-WUS, and the second indication message being used to determine whether to activate the terminal device to listen to LP-WUS.

[0006] In an embodiment of the present application, whether to activate the terminal device to monitor LP-WUS can be decided by a centralized unit. If the centralized unit determines that the terminal device should monitor LP-WUS, it can send a first indication message to the distributed unit to instruct the distributed unit to activate the terminal device to monitor LP-WUS. Alternatively, whether to activate the terminal device to monitor LP-WUS can also be decided by the distributed unit. In this case, the centralized unit can send a second indication message to the distributed unit, and the distributed unit can determine whether to activate the UE to monitor LP-WUS based on the second indication message. It can be seen that information exchange can be achieved between the centralized unit and the distributed unit in the embodiment of the present application. The centralized unit and the distributed unit can reach a consensus on whether to activate the terminal device to monitor LP-WUS, so as to achieve activation of the terminal device to monitor LP-WUS.

[0007] In an optional embodiment, the method further includes: determining the first indication information based on capability information of the terminal device and / or a measurement result of the terminal device. If a centralized unit decides whether to activate the terminal device to monitor LP-WUS, the centralized unit may decide whether to activate the terminal device to monitor LP-WUS based on the capability information of the terminal device and / or the measurement result of the terminal device. For example, the centralized unit may activate the UE to monitor LP-WUS when the channel condition of the terminal device is good, thereby saving power consumption of the terminal device.

[0008] In an optional embodiment, the second indication information includes the capability information of the terminal device and / or the measurement result of the terminal device. If the distribution unit decides whether to activate the UE to monitor LP-WUS, the centralized unit may send the information used for decision-making to the distribution unit for the distribution unit to make the decision. Optionally, if the distribution unit has already stored the information used for decision-making, the centralized unit may not need to send it. For example, if the distribution unit has already stored the capability information of the terminal device, the centralized unit may not send the second indication information to the distribution unit, or the centralized unit may send the second indication information, and the second indication information may include the measurement result of the terminal device but not the capability information of the terminal device, so as to reduce the transmission of redundant information.

[0009] In an optional embodiment, the method further includes: receiving first configuration information from the distributed unit, the first configuration information being used to configure the terminal device to monitor the LP-WUS; and sending the first configuration information to the terminal device. The information for configuring the terminal device to monitor the LP-WUS may be generated by the distributed unit, and the distributed unit may send the first configuration information to the centralized unit, so that the centralized unit can send the first configuration information to the terminal device.

[0010] In an optional embodiment, the first configuration information is further used to activate the terminal device to monitor LP-WUS. For example, in a scenario, once the terminal device monitors LP-WUS, it is also activated. The first configuration information can be used to configure and / or activate the terminal device to monitor LP-WUS.

[0011] In an optional embodiment, the method further includes: receiving fifth indication information from the terminal device, the fifth indication information being used to indicate that the terminal device is activated to monitor the LP-WUS. For example, in a scenario where the terminal device independently determines whether to activate the terminal device to monitor the LP-WUS, if the terminal device has activated the terminal device to monitor the LP-WUS, the fifth indication information may be sent to the centralized unit, so that the centralized unit is informed that the terminal device is activated to monitor the LP-WUS.

[0012] According to a second aspect, a second communication method is provided, which is applied to the distribution unit side, that is, the method can be executed by the distribution unit, or by a larger device including the distribution unit, or by a chip system or other functional module, which can realize the function of the distribution unit, and the chip system or functional module is, for example, arranged in the distribution unit. The distribution unit is, for example, a functional unit included in a network device, which may also be called a base station distribution unit, or may have other names. For example, the distribution unit is a DU. The network device includes, for example, an access network device, such as a base station. The method includes: receiving first indication information or second indication information from a centralized unit, the first indication information being used to instruct the distribution unit to activate the terminal device to listen to LP-WUS, and the second indication information being used to determine whether to activate the terminal device to listen to LP-WUS.

[0013] In an optional implementation, the second indication information includes capability information of the terminal device and / or a measurement result of the terminal device.

[0014] In an optional implementation, the method further includes: sending first configuration information to the central unit, where the first configuration information is used to configure the terminal device to monitor LP-WUS.

[0015] In an optional implementation, the first configuration information is further used to activate the terminal device to monitor LP-WUS.

[0016] In an optional implementation, the method further includes: sending first activation information to the terminal device, where the first activation information is used to activate the terminal device to monitor the LP-WUS.

[0017] Regarding the technical effects brought about by the second aspect or various optional implementations, reference may be made to the introduction to the technical effects of the first aspect or corresponding implementations.

[0018] On the third aspect, a third communication method is provided, which is applied to the terminal device side, that is, the method can be executed by the terminal device, or by other devices including the functions of the terminal device, or by a chip system (or, chip) or other functional module, which can realize the functions of the terminal device, and the chip system or functional module is, for example, set in the terminal device.

The method includes: receiving first information, the first information is used to instruct to configure the terminal device to listen to LP-WUS, and / or to instruct to stop or release a timer, the timer is used to determine the time when the terminal device enters the LP-WUS listening period; configuring the terminal device to listen to LP-WUS according to the first information, and stopping and / or releasing the timer.

[0019] The embodiments of the present application provide a mechanism for deconfiguring a terminal device to monitor LP-WUS. When the terminal device monitors LP-WUS, the embodiments of the present application also provide a method for handling a timer. For example, in addition to deconfiguring the terminal device to monitor LP-WUS, the terminal device can also stop and / or release the timer, thereby no longer entering the LP-WUS monitoring period based on the timer, so that the state of the timer is consistent with the state of the terminal device monitoring LP-WUS function.

[0020] In an optional embodiment, before receiving the first information, the terminal device monitors the LP-WUS through the WUR, and the first information is included in the first LP-WUS; or, before receiving the first information, the terminal device monitors the signal through the MR, and the first information is included in the RRC message. Before receiving the first information, if the terminal device monitors the LP-WUS through the WUR, or the terminal device is in the LP-WUS monitoring period, the network device may send the first information through the LP-WUS, so that the terminal device can receive the first information. Alternatively, before receiving the first information, if the terminal device monitors the signal through the MR, the network device may send the first information through an RRC message or a message of other protocol layers, so that the terminal device can receive the first information. Wherein, the other protocol layers include, for example, a media access control (MAC) layer or a physical layer, etc.

[0021] In an optional embodiment, the MR is turned on according to the first information, wherein, before receiving the first information, the terminal device monitors the LP-WUS through the WUR; or, according to the first information, the terminal device continues to monitor the signal through the MR, wherein, before receiving the first information, the terminal device monitors the signal through the MR. Before receiving the first information, if the terminal device monitors the LP-WUS through the WUR, or the terminal device is in the LP-WUS monitoring period, then when receiving the first information or after receiving the first information, the terminal device can turn on the MR, thereby entering the MR monitoring signal, and no longer monitors the LP-WUS through the WUR. Alternatively, before receiving the first information, if the terminal device monitors the signal through the MR, then when receiving the first information or after receiving the first information, the terminal device can continue to monitor the signal through the MR, and not monitor the LP-WUS through the WUR.

[0022] In an optional embodiment, the method further includes: receiving second information, the second information being used to configure the terminal device to monitor LP-WUS; and configuring the terminal device to monitor LP-WUS based on the second information.

For example, if the terminal device is already executing uplink and / or downlink services on the MR before receiving the second information, the terminal device may not immediately enter the LP-WUS monitoring period even after receiving the second information, thereby ensuring continued execution of services on the MR and improving service continuity.

[0024] In an optional embodiment, the method further includes: receiving first indication information, the first indication information being used to instruct the terminal device to keep passing the MR monitoring signal after the terminal device monitors that LP-WUS is configured (or, activated; or, configured and activated); or, the first indication information being used to instruct the terminal device to keep passing the MR monitoring signal after the terminal device monitors that LP-WUS is configured (or, activated; or, configured and activated) until information instructing the terminal device to enter the LP-WUS monitoring period is received and / or the timer times out. The terminal device does not immediately enter the LP-WUS monitoring period after the terminal device monitors that LP-WUS is configured and / or activated. This can be regarded as a mechanism that can be turned on or off. For example, the network device can send the first indication information to the terminal device to turn on or off the mechanism through the first indication information, which is more flexible.

[0086] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0087] In the embodiments of the present application, the number of nouns, unless otherwise specified, means "singular noun or plural noun", that is, "one or more". "At least one" means one or more, and "plural" means two or more. "And / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. For example, A / B means: A or B. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b and (or) c, means the following situations: a exists alone, b exists alone, c exists alone, a and b exist at the same time, a and c exist at the same time, b and c exist at the same time, or a, b and c exist at the same time, where a, b, c can be single or multiple.

[0088] In the embodiments of this application, ordinal numbers such as "first" and "second" are used to distinguish multiple objects and are not used to limit the size, content, order, timing, priority, or importance of multiple objects. In addition, the numbering of steps in the various embodiments introduced in this application is only to distinguish different steps and is not used to define the order between steps. For example, S301 can occur before S302, or after S302, or at the same time as S302.

[0089] Below, some terms or concepts in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0090] In an embodiment of the present application, the terminal device is a device with wireless transceiver capabilities, which can be a fixed device, a mobile device, a handheld device (such as a mobile phone), a wearable device, a vehicle-mounted device, or a wireless device built into the above devices (for example, a communication module, a modem, or a chip system, etc.). The terminal device is used to connect people, objects, machines, etc., and can be widely used in various scenarios, such as but not limited to the following scenarios: perception scenarios, cellular communications, device-to-device communication (D2D), vehicle to everything (V2X), machine-to-machine / machine-type communications (M2M / MTC), Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, self-driving, remote medical, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, drones, robots, indoor commercial scenarios (such as mobile phone screen projection, file sharing, mobile phone to VR glasses video transmission) and other scenarios. When the terminal device is applied to V2X, it can also be called a V2X device, for example, a smart car (or intelligent car), a digital car, an unmanned car (or driverless car or pilotless car or automobile), a self-driving car (or autonomous car), a pure electric vehicle (or battery EV), a hybrid electric vehicle (HEV), a range-extended EV (REEV), a plug-in hybrid electric vehicle (PHEV), a new energy vehicle (new energy vehicle), or a roadside unit (RSU). The terminal device can also be a device used in D2D communication, such as an electricity meter or water meter.

[0091] In addition, in the embodiment of the present application, the terminal device can also be a terminal device in the Internet of Things (IoT) system. IoT is an important part of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection.

[0092] The various terminal devices described above, if located on a vehicle (e.g., placed in or installed in a vehicle), can be considered as vehicle-mounted terminal devices, which are also referred to as on-board units (OBUs). The terminal device of the present application can also be an on-board module, on-board module, on-board component, on-board chip, or on-board unit built into a vehicle as one or more components or units, and the vehicle can implement the method of the present application through the built-in on-board module, on-board module, on-board component, on-board chip, or on-board unit.

[0093] The terminal device may sometimes be referred to as UE, terminal, access station, UE station, remote station, wireless communication device, or user equipment, etc.

[0094] In the embodiments of the present application, the communication device for implementing the terminal device function may be a terminal device, or may be a device capable of supporting the terminal device to implement the function, such as a chip system, which may be installed in the terminal device. In the technical solutions provided in the embodiments of the present application, the technical solutions provided in the embodiments of the present application are described by taking the terminal device as an example in which the device for implementing the terminal device function is a terminal device. In addition, for ease of description, the terminal device in the embodiments of the present application is described by taking a UE as an example.

[0095] The network devices in the embodiments of the present application include, for example, access network devices and / or core network devices. The access network device is a device with wireless transceiver functions, which is used to communicate with the terminal device. The access network devices include but are not limited to base stations (base transceiver station (BTS), node B (Node B), evolved node B (eNodeB) / eNB, or the next generation node B (gNodeB) / gNB), transmission reception points (TRP), base stations subsequently evolved by the third generation partnership project (3GPP), access nodes in wireless fidelity (Wi-Fi) systems, wireless relay nodes, wireless backhaul nodes, etc. The base station can be: a macro base station, a micro base station, a pico base station, a small station, a relay station, etc. Multiple base stations can support networks with the same access technology, or they can support networks with different access technologies. The base station can include one or more co-station or non-co-station transmission and receiving points. The access network device may also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario. The access network device may also be a server, etc. For example, the network device in the V2X technology may be a road side unit (RSU). The following describes the access network device using a base station as an example. The base station can communicate with the terminal device, or it can communicate with the terminal device through a relay station. The terminal device can communicate with multiple base stations in different access technologies. The core network device is used to implement functions such as mobility management, data processing, session management, policy and billing. The names of the devices that implement core network functions in systems with different access technologies may be different, and the embodiments of the present application are not limited to this. Taking the fifth generation mobile communication technology (5G) system as an example, the core network equipment includes, for example, access and mobility management function (AMF), session management function (SMF), policy control function (PCF) or user plane function (UPF), etc.

[0096] In the CU-DU architecture, the access network equipment may include one or more logical network elements such as a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The CU and DU may be configured separately or included in the same network element, such as a baseband unit (BBU). The RU may be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0097] The functions of a CU can be implemented by a single entity or by different entities. For example, the functions of a CU can be further divided, that is, the control plane and the user plane are separated and implemented by different entities, namely the control plane CU (e.g., CU-control plane (CP)) and the user plane CU (e.g., CU-user plane (UP)). The CU-CP and CU-UP can be coupled with the DU to jointly implement the functions of the access network device.

[0098] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open RAN (ORAN) system, CU may also be called an open CU (open CU, O-CU), DU may also be called an open DU (open DU, O-DU), CU-CP may also be called an open CU-CP (open CU-CP, O-CU-CP), CU-UP may also be called an open CU-UP (open CU-CP, O-CU-UP), and RU may also be called an open RU (open RU, O-RU). For convenience of description, the embodiments of the present application are described by taking CU, CU-CP, CU-UP, DU and RU as examples. Any of the CU (or CU-CP, CU-UP), DU and RU in the embodiments of the present application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0099] CU and DU can be configured according to the protocol layer functions of the wireless network they implement. For example, the CU is configured to implement the functions of the packet data convergence protocol (PDCP) layer and the protocol layers above it (such as the radio resource control (RRC) layer and / or the service data adaptation protocol (SDAP) layer, etc.); the DU is configured to implement the functions of the protocol layers below the PDCP layer (such as the radio link control (RLC), the media access control (MAC) layer, and / or the physical (PHY) layer, etc.). For another example, the CU is configured to implement the functions of the protocol layers above the PDCP layer (such as the RRC layer and / or the SDAP layer), and the DU is configured to implement the functions of the PDCP layer and the protocol layers below it (such as the RLC layer, the MAC layer, and / or the PHY layer, etc.). For a detailed description of each of the above protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP) or the technical specifications of other applicable communication protocols. The above division of the processing functions of the CU and DU according to the protocol layer is only an example, and can also be divided in other ways, which is not limited by the embodiments of the present application. For example, in one design, the CU or DU can also be divided into parts with partial processing functions of the protocol layer. In one design, part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU.

[0100] Optionally, in various embodiments of the present application, if the network device is a distributed architecture, for example, the network device includes a CU and a DU, or includes a CU-CP, a CU-UP and a DU, then the network device sends information to the UE, specifically, the DU included in the network device sends information to the UE; the network device receives information from the UE, specifically, the DU included in the network device receives information from the UE.

[0101] In the embodiments of the present application, the communication device for implementing the function of the network device may be a network device, or may be a device capable of supporting the network device to implement the function, such as a chip system, which may be installed in the network device. In the technical solutions provided in the embodiments of the present application, the technical solutions provided in the embodiments of the present application are described by taking the device for implementing the function of the network device as an example (for example, the device for implementing the function of the access network device is an access network device, and the device for implementing the function of the core network device is a core network device).

[0102] In the embodiments of the present application, when the provided method is executed by a device (e.g., a chip system) that can support a terminal device or a network device to implement the function, receiving / sending can be understood as input / output, that is, the device communicates with other devices / components in the terminal device or the network device. In addition, the processing performed by a single execution subject can also be divided into multiple execution subjects, which can be logically and / or physically separated.

[0103] The following describes the technical features involved in the embodiments of this application.

[0104] When a UE is in the radio resource control (RRC) idle or inactive state, it calculates the location of the paging frame (PF) and the paging occasion (PO) within a PF based on its UE identity (ID) to receive paging within the PO. Whether performing the paging process in the RRC idle or inactive state, or receiving data in the RRC connected state, the UE uses the same receiving module, which is called the MR. A UE operating in the MR can be understood as operating on the fifth generation (5G) new radio (NR) primary link.

[0105] In order to further reduce power consumption, the UE can also use a circuit independent of the MR to receive signals, such as circuit A. The circuit A can be implemented by a circuit or chip with a simple structure, and its power consumption is low. Among them, the circuit A is used to detect the wake-up signal (WUS) from the network device, etc., and the WUS received by the circuit A is also called LP-WUS. When the UE detects the LP-WUS or receives the LP-WUS and demodulates the wake-up indication information according to the information carried in the LP-WUS, the UE wakes up the MR that is turned off (or in a sleeping state) in the UE. Among them, the LP-WUS can be used to wake up at least one UE or at least one group of UEs. Circuit A is called a wake-up radio (WUR), for example. In order to reduce the power consumption of the WUR circuit, the LP-WUS signal usually adopts some simple modulation methods such as on-off keying (OOK); accordingly, the WUR in the UE adopts envelope detection to receive the LP-WUS. The UE using the circuit A to detect the wake-up signal, etc. can be called working on the WUR, or the WUR is in a working state.

[0106] For example, when the UE is turned on, it can first search for the signal of the NR main link in the MR. If the signal of the NR main link can be found, it can reside on the NR main link. If the signal of the NR main link indicates the configuration information of the LP-WUS, the UE can further search for the LP-WUS in circuit A according to the configuration information of the LP-WUS. If the LP-WUS can be found and the signal quality of the LP-WUS is good, the UE can work in circuit A. Alternatively, when the UE is turned on, it can first search for the signal of the NR main link in the MR. If the signal of the NR main link cannot be found, it can search for the LP-WUS according to the configuration information preset in the UE. If the LP-WUS can be found and the signal quality of the LP-WUS is good, the UE can work in circuit A.

[0107] For reference Figure 1 , which is a schematic diagram of the working mode of circuit A and MR, Figure 1 In the example, circuit A is a low-power circuit. After the UE detects the LP-WUS corresponding to itself after the low-power circuit is working, it can trigger the MR to be turned on to receive paging or initiate random access. If the UE does not detect the LP-WUS corresponding to itself, it does not need to trigger the MR to be turned on. The MR can remain off (or continue to sleep), thereby reducing the MR working time and saving the UE's power consumption.

[0108] After the introduction of WUR, when the UE monitoring LP-WUS is activated, the UE can monitor LP-WUS in WUR. However, for network devices including CU and / or DU, how to activate the UE to monitor LP-WUS remains to be studied.

[0109] In view of this, in the embodiment of the present application, whether to activate the UE to monitor LP-WUS can be decided by the CU. If the CU determines to activate the UE to monitor LP-WUS, it can send a first indication message to the DU to instruct the DU to activate the UE to monitor LP-WUS. Alternatively, whether to activate the UE to monitor LP-WUS can also be decided by the DU. The CU can send a second indication message to the DU, and the DU can determine whether to activate the UE to monitor LP-WUS based on the second indication message. It can be seen that information exchange can be achieved between the CU and the DU in the embodiment of the present application. The CU and the DU can reach a consensus on whether to activate the UE to monitor LP-WUS to achieve activation of the UE to monitor LP-WUS.

[0110] The technical solutions provided in the embodiments of the present application can be applied to 4G systems, such as long term evolution (LTE) systems, or can be applied to 5G systems, such as new radio (NR) systems, or can also be applied to next generation mobile communication systems or other similar communication systems, such as 6G systems, etc., without specific limitations. In addition, the technical solutions provided in the embodiments of the present application can also be applied to D2D scenarios, such as NR-D2D scenarios, etc., or to V2X scenarios, such as NR-V2X scenarios, etc. For example, the embodiments of the present application can be used in fields such as factory manufacturing, whole-house intelligence, intelligent driving, assisted driving, intelligent connected vehicles, or indoor commercial scenarios.

[0111] Please refer to Figure 2 , which is a schematic diagram of an application scenario of an embodiment of the present application. Figure 2 The system includes a UE and a network device, wherein the network device may include an access network device and / or a core network device. For example, the network device may send a downlink signal, and the UE may receive and measure the downlink signal. The downlink signal may include, for example, one or more of the following: an LP-WUS, a synchronization signal and a physical broadcast channel (PBCH) block (SSB), or a channel state information reference signal (CSI-RS).

[0112] In various embodiments of the present application, the main radio (MR) may also be referred to as the main receiver (MR), or may have other names. MR will be used as an example for the following description, and it can be understood that MR in the following description may refer to the main circuit or the main receiver. In various embodiments of the present application, the wake-up radio (WUR) may also be referred to as the wake-up receiver (WUR), the wake-up circuit, the low-power radio (LR), or the wake-up receiver module, etc., or may have other names. WUR will be used as an example for the following description, and it can be understood that WUR in the following description may refer to the wake-up radio or the wake-up receiver, and WUR in the following description may also be replaced by the wake-up circuit, the low-power circuit or the wake-up receiver module, etc. In various embodiments of the present application, the UE enters the LP-WUS monitoring period, which can also be understood or replaced as the UE monitoring LP-WUS, or the UE monitoring LP-WUS in the WUR, or the UE monitoring LP-WUS through the WUR, or the UE turning on the WUR, or the UE entering the WUR (for example, entering the WUR from the MR), or the UE switching to the WUR (for example, switching from the MR to the WUR), or the UE starting to work in the WUR. In various embodiments of the present application, the UE working in the MR can also be understood or replaced as the UE working in the MR, or the UE monitoring the signal in the MR (the signal includes, for example, a downlink signal, and the downlink signal includes, for example, a physical downlink control channel (PDCCH), and / or other downlink signals), or the UE monitoring the signal through the MR. In various embodiments of the present application, the UE remains working in the MR, or the UE remains working in the MR, or the UE remains monitoring the signal in the MR, which can be understood as the UE already monitoring the signal in the MR and will continue to monitor the signal in the MR.

[0113] In various embodiments of the present application, UE monitoring LP-WUS can be regarded as a function, which can be activated or deactivated, and can also be configured or deconfigured. Among them, in various embodiments of the present application, configuring or deconfiguring UE to monitor LP-WUS can also be understood or replaced by configuring or deconfiguring LP-WUS, or configuring or deconfiguring UE to monitor LP-WUS through WUR, or configuring or deconfiguring UE to monitor signals through WUR. In various embodiments of the present application, activating or deactivating UE to monitor LP-WUS can also be understood or replaced by activating or deactivating LP-WUS, or activating or deactivating UE to monitor LP-WUS through WUR, or activating or deactivating UE to monitor signals through WUR, etc. In various embodiments of the present application, "activate" can also be replaced by "enable".

[0114] Taking the network equipment including CU and DU as an example, in various embodiments of the present application, the information for activating the UE to monitor LP-WUS can be generated by the DU, and the information for configuring the UE to monitor LP-WUS can be generated by the DU. Whether to activate the UE to monitor LP-WUS can be decided by the CU or the DU; whether to configure the UE to monitor LP-WUS can be decided by the CU or the DU. The information for determining whether to activate the UE to monitor LP-WUS can be obtained by the CU; the information for determining whether to configure the UE to monitor LP-WUS can be obtained by the CU. Therefore, the embodiments of the present application provide a coordination mechanism between the CU and the DU to realize the activation or deactivation, or configuration or deconfiguration of the UE to monitor LP-WUS.

[0115] First, several scenarios of activating UE to monitor LP-WUS provided in the embodiments of the present application are introduced.

[0116] 1. Scene 1.

[0117] In this scenario, the network device may configure the UE to monitor LP-WUS, for example, by configuring the UE to monitor LP-WUS through RRC signaling. Once the UE is configured to monitor LP-WUS, it is also activated synchronously.

[0118] 2. Scene 2.

[0119] In this scenario, the network device may configure the UE to monitor the LP-WUS, for example, by configuring the UE to monitor the LP-WUS through RRC signaling. After configuration, the network device may activate the UE to monitor the LP-WUS, for example, by activating the UE to monitor the LP-WUS through layer (L) 1 or layer 2 signaling.

[0120] 3. Scene 3.

[0121] In this scenario, the network device can configure the UE to monitor LP-WUS, for example, by configuring the UE to monitor LP-WUS through RRC signaling. Furthermore, the network device can configure a threshold for the UE, and the UE can determine whether to activate LP-WUS monitoring based on the threshold, without the network device having to instruct the UE to activate LP-WUS monitoring. After the UE activates LP-WUS monitoring, it can notify the network device that LP-WUS monitoring has been activated.

[0122] The following describes the method provided by the embodiment of the present application in conjunction with the accompanying drawings. The various embodiments of this article can be applied to Figure 2 For example, the UE described in the various embodiments of this document may be Figure 2 The network device described in each embodiment of this document may be a UE Figure 2 Network devices in.

[0123] This application embodiment provides a first communication method, please refer to Figure 3 , is the flow chart of this method. Figure 3 The embodiment shown is applicable to the above-mentioned scenario 1 or scenario 2. Figure 3 In the illustrated embodiment, the network device includes a CU and a DU as an example.

[0124] S301: A CU sends first indication information to a DU, and the DU receives the first indication information from the CU. Alternatively, the CU sends second indication information to the DU, and the DU receives the second indication information from the CU. The first indication information may instruct the DU to activate UE monitoring for LP-WUS. The second indication information may be used to determine whether to activate UE monitoring for LP-WUS.

[0125] As an optional implementation, the CU determines whether to activate the UE to monitor the LP-WUS. If the CU determines to activate the UE to monitor the LP-WUS, the CU may send first indication information to the DU to instruct the DU to activate the UE to monitor the LP-WUS.

[0126] Optionally, the CU may determine whether to activate the UE to monitor LP-WUS based on the first information, where the first information may include, for example, one or more of the following: capability information of the UE, measurement results of the UE, or second information. The second information may indicate whether the measurement result of the UE meets the threshold or does not meet the threshold. Meeting the threshold, for example, means being greater than or equal to the threshold, and not meeting the threshold, for example, means being less than the threshold. The second information may indicate that the measurement result of the UE is greater than or equal to the threshold, or indicates that the measurement result of the UE is less than the threshold. In various embodiments of the present application, "greater than or equal to" and "greater than" may be interchangeable, and "less than or equal to" and "less than" may be interchangeable.

[0127] The UE's capability information may be sent by the UE to the CU. For example, before S301, the UE may send the UE's capability information to the CU. Optionally, the DU may transparently transmit the capability information to the CU, but the DU does not obtain the capability information. After obtaining the capability information, the CU may send the capability information to the DU, so that the DU can also obtain the capability information. For example, the capability information indicates whether the UE supports WUR and / or whether the UE supports receiving LP-WUS.

[0128] The measurement result may also be sent by the UE to the CU. For example, before S301, the UE may send the measurement result to the CU. For example, the UE may send the measurement result to the DU, and the DU may send the measurement result to the CU. Optionally, the DU may also obtain the measurement result in the process of forwarding the measurement result, or the DU may also transparently transmit the measurement result to the CU, and the DU does not obtain the measurement result. For example, the UE may perform measurements on the received downlink signal, such as performing radio resource management (RRM) measurements, to obtain measurement results. The downlink signal includes, for example, a downlink signal received through the WUR (for example, a signal based on OOK modulation) and / or a downlink signal received through the MR (for example, SSB and / or CSI-RS), and the measurement result may include a measurement result corresponding to the WUR, and / or a measurement result corresponding to the MR. Among them, the measurement results corresponding to MR include, for example, reference signal receiving power (RSRP) and / or reference signal receiving quality (RSRQ); the measurement results corresponding to WUR include, for example, RSRP and / or RSRQ. In order to distinguish them from the measurement results corresponding to MR, the measurement results corresponding to WUR can be called LP measurement results, for example, the RSRP corresponding to WUR is called LP-RSRP, and the RSRQ corresponding to WUR is called LP-RSRQ.

[0129] The second information may also be sent by the UE to the CU. For example, before S301, the UE may send the second information to the CU. For example, the UE may send the second information to the DU, and the DU may send the second information to the CU. Optionally, the DU may also obtain the second information in the process of forwarding the second information, or the DU may also transparently transmit the second information to the CU, and the DU does not obtain the second information. For example, the UE may perform measurements on the received downlink signal, such as performing RRM measurements, to obtain measurement results, and the UE may determine the size relationship between the measurement result and the threshold, thereby indicating the size relationship between the measurement result and the threshold through the second information. In this case, the UE does not need to send the measurement result to the network device, but can send the second information. Generally speaking, the amount of information in the second information may be less than the amount of information in the measurement result, thereby reducing the transmission overhead. The threshold may be configured by the network device, or predefined by the protocol, or preconfigured in the UE.

[0130] In each embodiment of the present application, the measurement result corresponding to WUR can also be replaced by the measurement result of WUR, or replaced by the measurement result based on WUR, or replaced by the measurement result obtained on WUR, or replaced by the measurement result obtained through WUR, or replaced by the measurement result obtained based on WUR, or replaced by the measurement result obtained based on OOK modulated signal, or replaced by the measurement result obtained by measuring OOK modulated signal, etc. There is no limitation on the description method, and the following description will take "the measurement result corresponding to WUR" as an example.

[0131] In each embodiment of the present application, the measurement result corresponding to MR can also be replaced by the measurement result of MR, or replaced by the measurement result based on MR, or replaced by the measurement result obtained on MR, or replaced by the measurement result obtained by MR, or replaced by the measurement result obtained based on MR, or replaced by the measurement result obtained based on MR, or replaced by the measurement result obtained based on SSB and / or CSI-RS, or replaced by the measurement result obtained by measuring SSB and / or CSI-RS, etc. There is no limitation on the description method, and the following description will be taken as an example of "measurement result corresponding to MR".

[0132] In various embodiments of the present application, the measurement results corresponding to the WUR may include the measurement results of the serving cell corresponding to the WUR, for example, the measurement results obtained by the UE measuring the serving cell at the WUR, or the measurement results obtained by the UE measuring the signal from the serving cell (for example, LP-WUS and / or other OOK modulation-based signals) at the WUR. The measurement results corresponding to the MR may include the measurement results of the serving cell corresponding to the MR, for example, the measurement results obtained by the UE measuring the serving cell at the MR, or the measurement results obtained by the UE measuring the signal from the serving cell (for example, SSB and / or CSI-RS, etc.) at the MR.

[0133] There are many ways for the CU to determine whether to activate the UE to monitor LP-WUS based on the first information. For example, if the UE's capability information indicates that the UE supports WUR and / or the UE supports receiving LP-WUS, the CU can determine to activate the UE to monitor LP-WUS. Alternatively, the CU receives a measurement result from the UE, and if the measurement result is greater than or equal to a threshold, the CU can determine to activate the UE to monitor LP-WUS. Alternatively, the CU receives a second information from the UE, and if the second information indicates that the UE's measurement result is greater than or equal to a threshold, the CU can determine to activate the UE to monitor LP-WUS. In addition to this, the CU can have more determination methods, which will not be elaborated on.

[0134] As another optional implementation, the DU determines whether to activate the UE to monitor LP-WUS. The CU may send second indication information to the DU, and the DU may determine whether to activate the UE to monitor LP-WUS based on the second indication information. For example, the second indication information may include one or more of the following: capability information of the UE, measurement results of the UE, or second information. The DU determines whether to activate the UE to monitor LP-WUS based on the second indication information in a manner similar to the determination method of the CU described above, and will not be further described.

[0135] Optionally, the first indication information may be included in a UE context modification request message, or in a UE context setup request message, or in a downlink RRC message transfer message, or in other messages. For example, a new indication field may be added to the UE context modification request message or the UE context setup message, and the indication field may include the first indication information. Optionally, the indication field may be included in the CU to DU RRC Information field in the UE context modification request message or the UE context setup message, or may also be included in other fields in the UE context modification request message or the UE context setup message, or may also not be included in any existing field in the UE context modification request message or the UE context setup message, but may exist as a newly added field. For example, the first indication information occupies one bit. If the value of the bit is "1" or "true", the DU is instructed to activate the UE to monitor LP-WUS, or the DU is instructed to configure and / or activate the UE to monitor LP-WUS; or, if the first indication information exists, the DU is instructed to activate the UE to monitor LP-WUS, or the DU is instructed to configure and / or activate the UE to monitor LP-WUS. Alternatively, the first indication information may also occupy two or more bits, and there is no limitation on this.

[0136] The implementation method of the second indication information is similar to that of the first indication information, and will not be described in detail.

[0137] Optionally, if the embodiment of the present application is applied to scenario 1, activation and configuration are the same behavior, and the first indication information can instruct the DU to configure and / or activate the UE to monitor LP-WUS; or, the second indication information can be used to determine whether to configure and / or activate the UE to monitor LP-WUS. In addition, the above-mentioned CU determines whether to activate the UE to monitor LP-WUS based on the first information, which can also be replaced by the CU determining whether to configure and / or activate the UE to monitor LP-WUS based on the first information, and the determination process is similar; or, the above-mentioned DU determines whether to activate the UE to monitor LP-WUS based on the second indication information, which can also be replaced by the DU determining whether to configure and / or activate the UE to monitor LP-WUS based on the second indication information, and the determination process is similar.

[0138] Alternatively, if the embodiment of the present application is applied to the above-mentioned scenario 2, activation and configuration are two separate processes, and the first indication information may instruct the DU to activate the UE to monitor LP-WUS, but not instruct the DU to configure the UE to monitor LP-WUS; alternatively, the first indication information may be used to determine whether to activate the UE to monitor LP-WUS, but not to determine whether to configure the UE to monitor LP-WUS. For scenario 2, S302 may optionally be included before S301.

[0139] S302: The CU sends third indication information to the DU, and the DU receives the third indication information from the CU. Alternatively, the CU sends fourth indication information to the DU, and the DU receives the fourth indication information from the CU. The third indication information may instruct the DU to configure the UE to monitor LP-WUS. The fourth indication information may be used to determine whether to configure the UE to monitor LP-WUS.

[0140] As an optional implementation manner, the CU determines whether to configure the UE to monitor the LP-WUS. If the CU determines to configure the UE to monitor the LP-WUS, the CU may send third indication information to the DU to instruct the DU to configure the UE to monitor the LP-WUS.

[0141] Optionally, the CU may determine whether to configure the UE to monitor LP-WUS based on third information, where the third information may include, for example, one or more of the following: capability information of the UE, measurement results of the UE, or fourth information. The fourth information may indicate whether the measurement result of the UE meets a threshold or does not meet a threshold. Meeting the threshold, for example, means being greater than or equal to the threshold, and not meeting the threshold, for example, means being less than the threshold. The fourth information may indicate that the measurement result of the UE is greater than or equal to the threshold, or that the measurement result of the UE is less than the threshold.

[0142] The measurement result of the UE involved in the third information may be the same as or different from the measurement result of the UE involved in the first information. The time when the UE obtains the measurement result involved in the third information may be earlier than the time when the UE obtains the measurement result involved in the first information. Accordingly, the result indicated by the second information may be the same as or different from the result indicated by the fourth information. For more information about the CU determination process, please refer to the relevant introduction of S301.

[0143] Alternatively, as another optional implementation, the DU determines whether to configure the UE to monitor LP-WUS. The CU may send fourth indication information to the DU, and the DU may determine whether to configure the UE to monitor LP-WUS based on the fourth indication information. For example, the fourth indication information includes one or more of the following: capability information of the UE, measurement results of the UE, or fifth information. The DU determines whether to configure the UE to monitor LP-WUS based on the fourth indication information. The determination method may be similar to the determination method of the CU described above, and will not be further described.

[0144] The implementation method of the third indication information is similar to the implementation method of the first indication information. Please refer to the introduction of S301 and will not be repeated here.

[0145] S303: The DU sends first configuration information to the CU. Correspondingly, the CU receives the first configuration information from the DU. For example, the first configuration information may be included in the CellGroupConfig field of the information sent by the DU to the CU, or may be included in other fields.

[0146] If the embodiment of the present application is applied to scenario 1, corresponding to S301 and S303, S303 may occur after S301. In this scenario, activation and configuration are the same behavior, and the first indication information may instruct the DU to configure and / or activate the UE to monitor LP-WUS; alternatively, the second indication information may be used to determine whether to configure and / or activate the UE to monitor LP-WUS. After receiving the first indication information, the DU may generate first configuration information and send the first configuration information to the CU through S303; alternatively, after receiving the second indication information, if the DU determines to configure and / or activate the UE to monitor LP-WUS, the DU may generate first configuration information and send the first configuration information to the CU through S303. The first configuration information may be used to configure and / or activate the UE to monitor LP-WUS. At this time, the first configuration information may also be referred to as first activation information, or may also be referred to as configuration activation information, etc., and there is no restriction on the name.

[0147] Optionally, in scenario 1, the method may further include S304, where the CU sends sixth information to the UE, and accordingly, the UE receives the sixth information. For example, S304 occurs after S303. The sixth information may include the first configuration information, and the sixth information may be used to configure and / or activate the UE to monitor LP-WUS. For example, the CU may directly send the first configuration information to the UE, in which case the sixth information and the first configuration information are the same information; or, the CU may also generate corresponding configuration information, and the sixth information may include the configuration information and the first configuration information. Among them, the CU may send the sixth information to the DU, and the DU may then send the sixth information to the UE.

[0148] Alternatively, if the embodiment of the present application is applied to scenario 2, it corresponds to S301, S302 and S303, for example, S302 occurs before S303, and S303 occurs before S301. In this scenario, activation and configuration are two processes. After the DU receives the third indication information, it can generate first configuration information and send the first configuration information to the CU through S303; or, after the DU receives the second indication information, if it is determined to configure the UE to listen to LP-WUS, it can generate first configuration information and send the first configuration information to the CU through S303. The first configuration information can configure the UE to listen to LP-WUS.

[0149] Optionally, in scenario 2, the method may further include S305 to S306.

[0150] S305: The CU sends the second configuration information to the UE. Correspondingly, the UE receives the second configuration information. For example, S305 occurs after S303.

[0151] The second configuration information may include the first configuration information, and the second configuration information may be used to configure the UE to monitor LP-WUS. For example, the CU may directly send the first configuration information to the UE, and the second configuration information and the first configuration information are the same information; alternatively, the CU may generate corresponding configuration information, and the second configuration information may include the configuration information and the first configuration information. The CU may send the second configuration information to the DU, and the DU may then send the second configuration information to the UE.

[0152] In step S306, the DU sends a first activation message to the UE. Accordingly, the UE receives the first activation message, which can be used to activate the UE to monitor the LP-WUS. For example, step S306 occurs after step S301. When activating the UE to monitor the LP-WUS, the DU can directly send the activation message (e.g., the first activation message) to the UE. That is, the DU does not need to send the first activation message to the CU, but can directly send it to the UE, thereby reducing the signaling interaction process between the CU and the DU.

[0153] In an embodiment of the present application, if the UE monitors LP-WUS and is activated, the UE can immediately enter the LP-WUR monitoring period, or the UE can immediately switch to WUR to monitor LP-WUS, or the UE can immediately turn on WUR, etc.

[0154] Optionally, in an embodiment of the present application, the UE monitoring LP-WUS may also be released (or deconfigured) or deactivated. The method for releasing the UE monitoring LP-WUS may be similar to the method for configuring the UE to monitor LP-WUS, for example, the CU or DU may decide; the method for deactivating the UE monitoring LP-WUS may be similar to the method for activating the UE monitoring LP-WUS, for example, the CU or DU may decide, and no further details will be given.

[0155] In an embodiment of the present application, whether to activate UE to monitor LP-WUS can be decided by the CU. If the CU determines to activate UE to monitor LP-WUS, it can send a first indication message to the DU to instruct the DU to activate UE to monitor LP-WUS; alternatively, whether to activate UE to monitor LP-WUS can also be decided by the DU. The CU can send a second indication message to the DU, and the DU can determine whether to activate UE to monitor LP-WUS based on the second indication message. Whether to configure UE to monitor LP-WUS is also implemented in a similar manner. It can be seen that information interaction can be achieved between the CU and DU in the embodiment of the present application. The CU and DU can reach an agreement on whether to configure and / or activate UE to monitor LP-WUS, so as to implement the configuration and / or activation of UE to monitor LP-WUS.

[0156] This application embodiment provides a second communication method, please refer to Figure 4 , is the flow chart of this method. Figure 4 The embodiment shown is applicable to the above scenario 3. Figure 4 In the illustrated embodiment, the network device includes a CU and a DU as an example.

[0157] S401: The CU sends first indication information to the DU, and correspondingly, the DU receives the first indication information from the CU. The first indication information may instruct the DU to activate the UE to monitor the LP-WUS, or instruct the UE to monitor that the LP-WUS is activated.

[0158] In scenario 3, the UE may determine by itself whether to activate UE monitoring LP-WUS. Optionally, if the UE activates UE monitoring LP-WUS, the UE may send fifth indication information to the CU, for which reference may be made to S402. For example, S402 occurs before S401. The fifth indication information may indicate that UE monitoring LP-WUS is activated, or indicate that UE monitoring LP-WUS is activated. The UE may send the fifth indication information to the DU, which in turn sends the fifth indication information to the CU. Optionally, the fifth indication information may be included in a measurement report, such as an RRM measurement report, or may be included in other signaling.

[0159] For example, the UE may determine whether to activate UE monitoring LP-WUS based on the UE capability information and / or the UE measurement result. The determination method may refer to Figure 3 In the embodiment shown, the CU determination method is introduced. In addition, the implementation method of the fifth indication information can be referred to Figure 3 Related introduction of S301 of the embodiment shown.

[0160] After receiving the fifth indication information, the CU may execute S401 to indicate to the DU that the UE monitors that the LP-WUS is activated.

[0161] Optionally, the method may further include S403 to S405, where S403 to S405 are a process in which the network device configures the UE to monitor the LP-WUS. For example, S403 to S405 may occur before S402.

[0162] S403: The CU sends third indication information to the DU, and the DU receives the third indication information from the CU. Alternatively, the CU sends fourth indication information to the DU, and the DU receives the fourth indication information from the CU. The third indication information may instruct the DU to configure the UE to monitor LP-WUS. The fourth indication information may be used to determine whether to configure the UE to monitor LP-WUS.

[0163] For more information about S403, please refer to Figure 3 S302 of the embodiment shown.

[0164] S404: The DU sends first configuration information to the CU. Accordingly, the CU receives the first configuration information from the DU. For example, the first configuration information may be included in the CellGroupConfig field of the information sent by the DU to the CU, or may be included in other fields. The first configuration information may configure the UE to monitor LP-WUS.

[0165] S405: The CU sends the second configuration information to the UE. Correspondingly, the UE receives the second configuration information.

[0166] The second configuration information may include the first configuration information, and the second configuration information may be used to configure the UE to monitor LP-WUS. For example, the CU may directly send the first configuration information to the UE, and the second configuration information and the first configuration information are the same information; alternatively, the CU may also generate corresponding configuration information, and the second configuration information may include the configuration information and the first configuration information. The CU may send the second configuration information to the DU, and the DU may then send the second configuration information to the UE. Optionally, the second configuration information may also include a threshold for comparison with the measurement result, and the UE may determine whether to activate the UE to monitor LP-WUS based on the measurement result and the threshold.

[0167] In an embodiment of the present application, if the UE monitors LP-WUS and is activated, the UE can immediately enter the LP-WUR monitoring period, or the UE can immediately switch to WUR to monitor LP-WUS, or the UE can immediately turn on WUR, etc.

[0168] Optionally, in an embodiment of the present application, the UE monitoring LP-WUS may also be deactivated. The method of deactivating the UE monitoring LP-WUS may be similar to the method of activating the UE monitoring LP-WUS. For example, the decision may be made by the UE, which will not be elaborated herein.

[0169] In an embodiment of the present application, whether to configure the UE to monitor LP-WUS can be decided by the CU. If the CU determines that the UE should be configured to monitor LP-WUS, the CU can send a third indication message to the DU to instruct the DU to configure the UE to monitor LP-WUS; alternatively, whether to configure the UE to monitor LP-WUS can also be decided by the DU. The CU can send a fourth indication message to the DU, and the DU can determine whether to configure the UE to monitor LP-WUS based on the fourth indication message. It can be seen that information interaction can be achieved between the CU and the DU in the embodiment of the present application. The CU and the DU can reach a consensus on whether to configure the UE to monitor LP-WUS to implement the configuration of the UE to monitor LP-WUS. In addition, if the CU determines that the UE has activated the UE to monitor LP-WUS, the CU can also inform the DU so that the CU, the DU, and the UE can align the UE behavior.

[0170] After the introduction of WUR, the embodiments of the present application take into account that some behaviors of the UE have not yet been determined. Therefore, some working mechanisms of the UE after the introduction of WUR are provided through the following embodiments.

[0171] This application embodiment provides a third communication method, please refer to Figure 5 , is the flow chart of this method. Figure 5 The illustrated embodiment is applicable to the above-mentioned scenario 1.

[0172] S501: A network device sends first information, and a UE receives the first information accordingly.

[0173] The first information may instruct to configure the UE to monitor LP-WUS, and / or instruct to stop or release the timer. The timer may be used to determine the time when the UE enters the LP-WUS monitoring period. For example, the timer may be turned on when the UE turns on MR, or the UE switches from WUR to MR to monitor PDCCH. When the timer expires, the UE may enter the LP-WUS monitoring period, or the UE may switch to WUR to monitor LP-WUS, or the UE may turn on WUR, etc. When the UE monitors the signal in MR, the WUR may be kept on, or the WUR may be turned off. If the WUR remains in the on state when the UE monitors the signal at the MR, then if the UE wants to monitor the LP-WUS at the WUR, it can be understood that the UE switches to the WUR to monitor the LP-WUS, or the UE enters the LP-WUS monitoring period, etc., that is, the UE does not have to perform the behavior of turning on the WUR; or, if the WUR is in the off state when the UE monitors the signal at the MR, then if the UE wants to monitor the LP-WUS at the WUR, it can be understood that the UE turns on the WUR, or the UE turns on and enters the WUR, or the UE turns on the WUR to enter the LP-WUS monitoring period, or the UE enters the LP-WUS monitoring period, etc., that is, the UE can perform the behavior of turning on the WUR.

[0174] Among them, if the first information indicates to configure the UE to monitor LP-WUS, but does not indicate to stop or release the timer; after receiving the first information, the UE can configure to monitor LP-WUS, and can also stop or release the timer on its own. Alternatively, if the first information indicates to stop or release the timer, but does not indicate to configure the UE to monitor LP-WUS; after receiving the first information, the UE stops or releases the timer according to the instruction of the first information, and can also configure the UE to monitor LP-WUS on its own. Alternatively, if the first information indicates to configure the UE to monitor LP-WUS and indicates to stop or release the timer; after receiving the first information, the UE can configure the UE to monitor LP-WUS according to the instruction of the first information, and stop or release the timer. The UE stops or releases the timer, for example, including: if the timer is currently in a running state (for example, the UE monitors the signal through the MR before receiving the first information, the timer may be in a running state when the first information is received), the UE may stop the timer, or stop and release the timer; or, if the timer is currently in an off state (for example, the UE is in an LP-WUS monitoring period before receiving the first information, the timer may be in an off state when the first information is received), the UE may release the timer.

[0175] Before receiving the first information, the UE may be working in WUR, or listening to signals through WUR, or may be working in MR, or listening to signals through MR, and the network device can also clearly know the status of the UE. Optionally, before receiving the first information, if the UE is listening to LP-WUS through WUR, the first information may be included in LP-WUS, for example, included in the first LP-WUS; the UE can receive the first LP-WUS through WUR, so that it can be determined to configure the UE to listen to LP-WUS. In addition, if the UE is listening to LP-WUS through WUR before receiving the first information, then optionally, when or after receiving the first information, the UE can turn on MR according to the first information, thereby listening to signals through MR. Since the UE stops or releases the timer, indicating that the timer will no longer time out, the UE may always keep listening to signals in MR.

[0176] Alternatively, before receiving the first information, if the UE is monitoring signals through the MR, the first information may be included in an RRC message or a message at another protocol layer; the UE may receive the first information through the MR, thereby determining to configure the UE to monitor LP-WUS. Furthermore, if the UE is monitoring signals through the MR before receiving the first information, then optionally, when or after receiving the first information, the UE may continue to monitor signals through the MR or remain operating in the MR based on the first information. Since the UE stops or releases the timer, indicating that the timer will no longer time out, the UE may continue to monitor signals through the MR.

[0177] In an embodiment of the present application, if the UE receives the first information, the UE can be configured to monitor LP-WUS, wherein deconfiguring the UE to monitor LP-WUS can also be considered as deconfiguring the UE to monitor LP-WUS through WUR. That is, the UE monitoring LP-WUS can be deconfigured when the first information is received, so that the UE can no longer work in WUR, which is equivalent to providing a mechanism for how the UE monitoring LP-WUS is deconfigured. In addition, the timer is used to determine the timing for the UE to enter the LP-WUS monitoring period. Therefore, if the UE monitoring LP-WUS is deconfigured, the UE can also stop and / or release the timer, so as to no longer enter the LP-WUS monitoring period according to the timer, so that the state of the timer is consistent with the state of the UE monitoring LP-WUS.

[0178] Optionally, before S501, the method may further include S502, the network device sends the second information, and accordingly, the UE receives the second information. The second information can be used to configure the UE to monitor LP-WUS, and the UE can configure the UE to monitor LP-WUS according to the second information. Since the embodiment of the present application can be used for scenario 1, the second information can also be used to activate the UE to monitor LP-WUS, for example, the second information can be used to configure and / or activate the UE to monitor LP-WUS. After the UE receives the second information, it can activate the UE to monitor LP-WUS. Optionally, in the embodiment of the present application, the UE activates the UE to monitor LP-WUS, which can be regarded as the UE activating the function of the UE to monitor LP-WUS, but the UE may not immediately switch to the WUR to monitor LP-WUS, or the UE may not immediately enter the LP-WUS monitoring period.

[0179] For example, before receiving the second information, the UE monitoring LP-WUS is not configured and activated, so the UE can monitor the signal through the MR. Optionally, after the UE configures and / or activates the UE monitoring LP-WUS according to the second information, it can continue to monitor the signal through the MR, that is, the UE does not immediately enter the LP-WUS monitoring period. For example, before receiving the second information, the UE has an uplink service and / or downlink service being executed on the MR, then the UE may not immediately enter the LP-WUS monitoring period even if it receives the second information, which can ensure that the MR's service continues to be executed and improve service continuity. Moreover, if the UE enters the LP-WUS monitoring period immediately after receiving the second information, since the UE still has services to be executed on the MR, the UE may need to switch to the MR monitoring signal after entering the LP-WUS monitoring period, which makes the UE's behavior complexity higher. Through the solution of the embodiment of the present application, the switching process of the UE between WUR and MR can also be reduced, which is conducive to reducing the complexity of UE implementation.

[0180] If the UE does not immediately enter the LP-WUS listening period after receiving the second information, in order to meet the UE's monitoring requirements in the WUR, the embodiment of the present application also provides a method for causing the UE to enter the LP-WUS listening period. Optionally, the UE may enter the LP-WUS listening period when or after receiving the third information, wherein the third information may instruct the UE to enter the LP-WUS listening period. For example, after sending the second information, the network device may send the third information, and the UE may enter the LP-WUS listening period based on the third information.

[0181] Alternatively, the UE starts a timer after receiving the second information, and the UE may enter the LP-WUS listening period when the timer expires. The timer may be used to determine the time when the UE enters the LP-WUS listening period. For example, the timer may be started when the UE turns on MR. When the timer expires, the UE may enter the LP-WUS listening period, or the UE may switch to WUR to listen to LP-WUS, or the UE may turn on WUR, etc.

[0182] Optionally, the UE does not immediately enter the LP-WUS listening period after the UE monitors that the LP-WUS is configured and / or activated, which can be regarded as a mechanism that can be turned on or off. For example, the network device can send a first indication message to the UE, and the first indication message can instruct the UE to enter the LP-WUS listening period after the UE monitors that the LP-WUS is configured and / or activated. Under this indication, if the UE receives the first information, it can enter the LP-WUS listening period without continuing to monitor the MR signal.

[0183] Alternatively, the first indication information may instruct the UE not to enter the LP-WUS listening period after the UE monitors that the LP-WUS is configured and / or activated, or instruct the UE not to enter the LP-WUS listening period after the UE monitors that the LP-WUS is configured and / or activated, or instruct the UE to continue monitoring signals through the MR after the UE monitors that the LP-WUS is configured and / or activated. Under this indication, if the UE receives the first indication information, it may continue monitoring signals through the MR without entering the LP-WUS listening period. Optionally, the first indication information may also instruct the UE to enter the LP-WUS listening period upon receiving information instructing the UE to enter the LP-WUS listening period and / or upon a timer expiration. For example, the first indication information may instruct the UE to continue monitoring signals through the MR after the UE monitors that the LP-WUS is configured and / or activated until receiving information instructing the UE to enter the LP-WUS listening period and / or until the timer expires. If the UE receives the first indication information, it may continue monitoring signals through the MR, and upon receiving third information and / or the timer expires, it may enter the LP-WUS listening period. Alternatively, the first indication information may not indicate that the UE enters the LP-WUS listening period when receiving information for instructing the UE to enter the LP-WUS listening period and / or when the timer expires. This behavior may be predefined by the protocol or be the default behavior of the UE, that is, as long as the UE maintains the MR listening signal after the UE monitors the LP-WUS and is configured and / or activated, the UE can enter the LP-WUS listening period when receiving information for instructing the UE to enter the LP-WUS listening period and / or when the timer expires.

[0184] Through the above mechanism, the UE can enter the LP-WUS listening period to meet the UE's monitoring requirements for the LP-WUS; and the UE does not need to enter the LP-WUS listening period immediately when the UE monitors the LP-WUS and is activated, to meet the UE's monitoring requirements on the MR.

[0185] The embodiments of the present application provide a mechanism for deconfiguring the UE to monitor LP-WUS. When the UE monitors LP-WUS, the embodiments of the present application also provide a method for handling the timer. For example, in addition to deconfiguring the UE to monitor LP-WUS, the UE can also stop and / or release the timer, thereby no longer entering the LP-WUS monitoring period based on the timer, so that the state of the timer is consistent with the state of the UE monitoring LP-WUS function.

[0186] This embodiment of the application provides a fourth communication method, please refer to Figure 6 , is the flow chart of this method. Figure 6 The illustrated embodiment is applicable to the above-mentioned scenario 2.

[0187] S601: A network device sends fourth information, and correspondingly, a UE receives the fourth information.

[0188] The fourth information may indicate to deactivate the UE to monitor LP-WUS, and / or indicate to stop or not start the timer. Among them, the timer can be used to determine the time when the UE enters the LP-WUS monitoring period. For example, the timer can be turned on when the UE turns on MR. When the timer times out, the UE can enter the LP-WUS monitoring period, or the UE can switch to WUR to monitor LP-WUS, or the UE can turn on WUR, etc. Among them, when the UE monitors the signal in MR, the WUR can be kept on, or the WUR can be turned off. If the WUR remains in the on state when the UE monitors the signal at the MR, then if the UE wants to monitor the LP-WUS at the WUR, it can be understood that the UE switches to the WUR to monitor the LP-WUS, or the UE enters the LP-WUS monitoring period, etc., that is, the UE does not have to perform the behavior of turning on the WUR; or, if the WUR is in the off state when the UE monitors the signal at the MR, then if the UE wants to monitor the LP-WUS at the WUR, it can be understood that the UE turns on the WUR, or the UE turns on and enters the WUR, or the UE turns on the WUR to enter the LP-WUS monitoring period, or the UE enters the LP-WUS monitoring period, etc., that is, the UE can perform the behavior of turning on the WUR.

[0189] Among them, if the fourth information indicates to deactivate the UE's monitoring of LP-WUS, but does not indicate to stop or not start the timer; after receiving the fourth information, the UE can deactivate the monitoring of LP-WUS, and can also stop or not start the timer on its own. Alternatively, if the fourth information indicates to stop or not start the timer, but does not indicate to deactivate the UE's monitoring of LP-WUS; after receiving the fourth information, the UE stops or does not start the timer according to the instruction of the fourth information, and can also deactivate the UE's monitoring of LP-WUS on its own. Alternatively, if the fourth information indicates to deactivate the UE's monitoring of LP-WUS, and indicates to stop or not start the timer; after receiving the fourth information, the UE can deactivate the UE's monitoring of LP-WUS, and stop or not start the timer according to the instruction of the fourth information. Among them, the UE stops or does not start the timer, for example, including, if the timer is currently in a running state (for example, the UE is monitoring the signal through the MR before receiving the fourth information, then the timer may be in a running state when the fourth information is received), then the UE may stop the timer, so that the timer enters a stopped state, optionally, the UE may reset and stop the timer; or, if the timer is currently in an off state (for example, the UE is in an LP-WUS monitoring period before receiving the fourth information, then the timer may be in an off state when the fourth information is received), then the UE may not start the timer, so that the timer remains in an off state.

[0190] Before receiving the fourth information, the UE may be working in WUR, or listening to signals through WUR, or may be working in MR, or listening to signals through MR, and the network device can also clearly understand the status of the UE. Optionally, before receiving the fourth information, if the UE is listening to LP-WUS through WUR, the fourth information may be included in the LP-WUS, for example, included in the first LP-WUS; the UE can receive the first LP-WUS through WUR, thereby determining to deactivate the UE's listening to LP-WUS. In addition, if the UE is listening to LP-WUS through WUR before receiving the fourth information, then optionally, when or after receiving the fourth information, the UE can turn on MR according to the fourth information, thereby listening to signals through MR. Since the UE stops or does not start the timer, indicating that the timer will no longer time out, the UE may always keep listening to signals in MR.

[0191] Alternatively, before receiving the fourth information, if the UE is monitoring signals through the MR, the fourth information may be included in an RRC message or a message at another protocol layer; the UE may receive the fourth information through the MR, thereby determining to deactivate UE monitoring of the LP-WUS. Furthermore, if the UE is monitoring signals through the MR before receiving the fourth information, then optionally, when or after receiving the fourth information, the UE may continue to monitor signals through the MR or continue operating in the MR based on the fourth information. Since the UE stops or does not start the timer, indicating that the timer will no longer time out, the UE may continue to monitor signals through the MR.

[0192] In an embodiment of the present application, if the UE receives the fourth information, the UE can be deactivated from monitoring LP-WUS, wherein deactivating the UE from monitoring LP-WUS can also be considered as deactivating the UE from monitoring LP-WUS through WUR. That is, the UE monitoring LP-WUS can be deactivated when the fourth information is received, so that the UE may not work in WUR, which is equivalent to providing a mechanism for how the UE monitoring LP-WUS is deactivated. In addition, the timer is used to determine the timing for the UE to enter the LP-WUS monitoring period. Therefore, if the UE monitoring LP-WUS is deactivated, the UE can also stop and / or not start the timer, so that it may not enter the LP-WUS monitoring period according to the timer, so that the state of the timer is consistent with the state of the UE monitoring LP-WUS.

[0193] Optionally, before S601, the method may further include S602 to S603. S602 to S603 are the process of the network device configuring the UE to monitor the LP-WUS, and the network device instructing the UE to activate the monitoring of the LP-WUS.

[0194] S602: The network device sends fifth information. Correspondingly, the UE receives the fifth information. The fifth information may be, for example, an RRC message, or a message of another protocol layer.

[0195] The fifth information may be used to configure the UE to monitor the LP-WUS, and the UE may be configured to monitor the LP-WUS according to the fifth information.

[0196] S603: The network device sends sixth information. Correspondingly, the UE receives the sixth information. The sixth information may be, for example, a layer 1 message or a layer 2 message, or a message of another protocol layer.

[0197] The sixth information may be used to activate the UE to monitor the LP-WUS, and the UE may activate the UE to monitor the LP-WUS according to the sixth information.

[0198] Optionally, in an embodiment of the present application, the UE activates the UE to monitor LP-WUS, which can be regarded as the UE activating the function of the UE to monitor LP-WUS, but the UE may not immediately switch to the WUR to monitor LP-WUS, or the UE may not immediately enter the LP-WUS monitoring period.

[0199] For example, before receiving the sixth information, the UE monitoring LP-WUS is not activated, so the UE can monitor the signal through the MR. Then, optionally, after the UE activates the UE monitoring LP-WUS according to the sixth information, it can continue to monitor the signal through the MR, that is, the UE does not immediately enter the LP-WUS monitoring period. For this, please refer to Figure 5 Related introduction of the embodiment shown.

[0200] If the UE does not immediately enter the LP-WUS listening period after receiving the sixth information, in order to meet the UE's monitoring requirements in the WUR, the embodiment of the present application also provides a method for causing the UE to enter the LP-WUS listening period. Optionally, the UE may enter the LP-WUS listening period when or after receiving the third information, wherein the third information may instruct the UE to enter the LP-WUS listening period. For example, after sending the sixth information, the network device may send the third information again, and the UE may enter the LP-WUS listening period based on the third information.

[0201] Alternatively, the UE starts a timer after receiving the sixth information, and the UE may enter the LP-WUS listening period when the timer expires. The timer may be used to determine the time when the UE enters the LP-WUS listening period. For example, the timer may be started when the UE turns on MR. When the timer expires, the UE may enter the LP-WUS listening period, or the UE may switch to WUR to listen to LP-WUS, or the UE may turn on WUR, etc.

[0202] Optionally, the UE not immediately entering the LP-WUS listening period after the UE monitors the LP-WUS is configured and / or activated can be considered a mechanism that can be enabled or disabled. For example, the network device can send a first indication message to the UE, and the first indication message can instruct the UE to enter the LP-WUS listening period after the UE monitors the LP-WUS is activated. Under this indication, if the UE receives the first information, it can enter the LP-WUS listening period without continuing to monitor the MR signal.

[0203] Alternatively, the first indication information may instruct the UE not to enter the LP-WUS listening period after the UE monitors the LP-WUS and is activated, or instruct the UE not to enter the LP-WUS listening period after the UE monitors the LP-WUS and is activated, or instruct the UE to continue monitoring signals through the MR after the UE monitors the LP-WUS and is activated. Under this indication, if the UE receives the first indication information, it may continue monitoring signals through the MR and not enter the LP-WUS listening period. Optionally, the first indication information may also instruct the UE to enter the LP-WUS listening period upon receiving information instructing the UE to enter the LP-WUS listening period and / or upon a timer expiration. For example, the first indication information may instruct the UE to continue monitoring signals through the MR after the UE monitors the LP-WUS and is activated until receiving information instructing the UE to enter the LP-WUS listening period and / or until a timer expires; if the UE receives the first indication information, it may continue monitoring signals through the MR, and upon receiving third information and / or a timer expiration, the UE may enter the LP-WUS listening period. Alternatively, the first indication information may not indicate that the UE enters the LP-WUS listening period when receiving information for instructing the UE to enter the LP-WUS listening period and / or when the timer expires. This behavior may be predefined by the protocol or be the default behavior of the UE, that is, as long as the UE maintains the MR listening signal after the UE monitors the LP-WUS and is activated, the UE can enter the LP-WUS listening period when receiving information for instructing the UE to enter the LP-WUS listening period and / or when the timer expires.

[0204] Through the above mechanism, the UE can enter the LP-WUS listening period to meet the UE's monitoring requirements for the LP-WUS; and the UE does not need to enter the LP-WUS listening period immediately when the UE monitors the LP-WUS and is activated, to meet the UE's monitoring requirements on the MR.

[0205] The embodiments of the present application provide a mechanism for deactivating UE monitoring of LP-WUS. When UE monitoring of LP-WUS is deactivated, the embodiments of the present application also provide a method for handling a timer. For example, in addition to deactivating UE monitoring of LP-WUS, the UE can also stop and / or not start the timer, thereby not entering the LP-WUS monitoring period based on the timer, so that the state of the timer is consistent with the state of the UE monitoring of LP-WUS.

[0206] This embodiment of the application provides a fourth communication method, please refer to Figure 7 , is the flow chart of this method. Figure 7 The illustrated embodiment is applicable to the above-mentioned scenario 3.

[0207] S701: A UE determines that a first measurement result is less than or equal to a first threshold, where the first measurement result is a measurement result of the UE.

[0208] For example, the UE may perform measurements on the received downlink signal, such as performing RRM measurements, to obtain a first measurement result, and the UE may determine the size relationship between the first measurement result and the first threshold. The downlink signal includes, for example, a downlink signal received through the WUR (e.g., a signal based on OOK modulation) and / or a downlink signal received through the MR (e.g., SSB and / or CSI-RS). The first measurement result may include a measurement result corresponding to the WUR, and / or a measurement result corresponding to the MR. For more information about the measurement results, please refer to Figure 3 S301 of the embodiment shown.

[0209] S702: The UE deactivates UE monitoring of LP-WUS and stops or does not start a timer.

[0210] Among them, the timer can be used to determine the time when the UE enters the LP-WUS listening period. For example, the timer can be turned on when the UE turns on MR. When the timer times out, the UE can enter the LP-WUS listening period, or the UE can switch to WUR to listen to LP-WUS, or the UE can turn on WUR, etc. Among them, when the UE monitors the signal in MR, the WUR can be kept in the turned-on state, or the WUR can be turned off. If the WUR remains in the turned-on state when the UE monitors the signal in MR, then if the UE wants to monitor LP-WUS in WUR, it can be understood that the UE switches to WUR to monitor LP-WUS, or the UE enters the LP-WUS listening period, etc., that is, the UE does not have to perform the behavior of turning on WUR; or, if the WUR is in the turned-off state when the UE monitors the signal in MR, then if the UE wants to monitor LP-WUS in WUR, it can be understood that the UE turns on WUR, or the UE turns on and enters WUR, or the UE turns on WUR to enter the LP-WUS listening period, or the UE enters the LP-WUS listening period, etc., that is, the UE can perform the behavior of turning on WUR.

[0211] In an embodiment of the present application, the UE decides on its own whether to deactivate the UE's monitoring of LP-WUS, without the need for instructions from a network device, making the deactivation behavior more efficient. Among them, when the UE determines that the first measurement result is less than or equal to the first threshold, if the timer is currently in a running state, (for example, the UE monitors the signal through the MR before determining that the first measurement result is less than or equal to the first threshold, then the timer may be in a running state when determining that the first measurement result is less than or equal to the first threshold), then the UE can stop the timer, so that the timer enters a stopped state, and optionally, the UE can reset and stop the timer; or, if the timer is currently in a closed state (for example, the UE is in an LP-WUS monitoring period before determining that the first measurement result is less than or equal to the first threshold, then the timer may be in a closed state when determining that the first measurement result is less than or equal to the first threshold), then the UE may not start the timer, so that the timer remains in a closed state.

[0212] Before determining that the first measurement result is less than or equal to the first threshold, the UE may be operating in WUR, or monitoring signals through WUR, or may be operating in MR, or monitoring signals through MR, and the network device can also clearly understand the status of the UE. Optionally, before determining that the first measurement result is less than or equal to the first threshold, if the UE is monitoring LP-WUS through WUR, then optionally, when the UE determines that the first measurement result is less than or equal to the first threshold or after determining that the first measurement result is less than or equal to the first threshold, the UE may turn on MR, thereby monitoring signals through MR. Since the UE stops or does not start the timer, indicating that the timer will no longer time out, the UE may always keep monitoring signals in MR.

[0213] Alternatively, before determining that the first measurement result is less than or equal to the first threshold, if the UE is monitoring signals through the MR, then optionally, when the UE determines that the first measurement result is less than or equal to the first threshold or after determining that the first measurement result is less than or equal to the first threshold, the UE may continue to monitor signals through the MR, or continue to operate in the MR. Since the UE stops or does not start the timer, indicating that the timer will no longer time out, the UE may always continue to monitor signals through the MR.

[0214] If the UE deactivates the UE monitoring LP-WUS, then optionally, the UE may send seventh information to the network device, where the seventh information may indicate that the UE monitoring LP-WUS is deactivated, so that the network device can clearly understand the status of the UE.

[0215] In an embodiment of the present application, if the UE determines that the first measurement result is less than or equal to the first threshold, the UE monitoring LP-WUS can be deactivated, wherein deactivating the UE monitoring LP-WUS can also be considered as deactivating the UE monitoring LP-WUS through the WUR. That is, the UE monitoring LP-WUS can be deactivated when it is determined that the first measurement result is less than or equal to the first threshold, so that the UE may not work in the WUR, which is equivalent to providing a mechanism for how the UE monitoring LP-WUS is deactivated. In addition, the timer is used to determine the timing for the UE to enter the LP-WUS monitoring period. Therefore, if the UE monitoring LP-WUS is deactivated, the UE can also stop and / or not start the timer, so that it can not enter the LP-WUS monitoring period according to the timer, so that the state of the timer is consistent with the state of the UE monitoring LP-WUS.

[0216] As described above, the method for UE to deactivate UE monitoring of LP-WUS is described. Before UE monitoring of LP-WUS is deactivated, it can be activated first. To this end, optionally, before S701, the method may further include S703, where the network device sends fifth information to the UE, and accordingly, the UE receives the fifth information. The fifth information can be used to configure the UE to monitor LP-WUS, and the UE can configure the UE to monitor LP-WUS according to the fifth information. Optionally, the fifth information may further include a first threshold for comparison with the measurement result, or the first threshold may be predefined or preconfigured in the UE through a protocol, and the UE may make a judgment in S701 based on the first measurement result and the first threshold.

[0217] After the UE receives the fifth information, it only configures the UE to monitor LP-WUS, and the UE monitoring LP-WUS may not be activated. Optionally, the UE can determine whether to activate the UE to monitor LP-WUS in combination with the measurement results and the corresponding threshold. For example, the UE can obtain a second measurement result through measurement. If the second measurement result is greater than or equal to the second threshold, the UE can activate the UE to monitor LP-WUS; or, if the second measurement result is less than the second threshold, the UE may not activate the UE to monitor LP-WUS. Optionally, the second threshold may be configured by the fifth information, or it may be predefined or preconfigured in the UE through a protocol. For example, the UE may perform measurements on the received downlink signal, such as performing RRM measurements, to obtain a second measurement result, and the UE may determine the size relationship between the second measurement result and the second threshold. The downlink signal, for example, includes a downlink signal received through WUR (such as a signal based on OOK modulation) and / or a downlink signal received through MR (such as SSB and / or CSI-RS). The second measurement result may include a measurement result corresponding to WUR, and / or a measurement result corresponding to MR. For more information about the measurement results, please refer to Figure 3In S301 of the embodiment shown, the first measurement result is completely identical to, partially identical to, or completely different from the second measurement result.

[0218] If the UE activates UE monitoring LP-WUS, then optionally, the UE may send eighth information to the network device, where the eighth information may indicate that the UE monitoring LP-WUS is activated, so that the network device can clearly understand the status of the UE.

[0219] Optionally, in an embodiment of the present application, the UE activates the UE to monitor LP-WUS, which can be regarded as the UE activating the function of the UE to monitor LP-WUS, but the UE may not immediately switch to the WUR to monitor LP-WUS, or the UE may not immediately enter the LP-WUS monitoring period.

[0220] For example, before the UE monitors LP-WUS, the UE can monitor the signal through MR. Then, optionally, after the UE activates the UE monitor LP-WUS, the UE can continue to monitor the signal through MR, that is, the UE does not immediately enter the LP-WUS monitoring period. Figure 5 Related introduction of the embodiment shown.

[0221] If the UE does not immediately enter the LP-WUS listening period after activating the UE to listen to the LP-WUS, in order to meet the UE's listening requirements in the WUR, the embodiment of the present application also provides a method for the UE to enter the LP-WUS listening period. Optionally, the UE can enter the LP-WUS listening period when or after receiving the third information, wherein the third information can instruct the UE to enter the LP-WUS listening period. For example, the network device can determine whether the UE enters the LP-WUS listening period. If it is considered that the UE can enter the LP-WUS listening period, the third information can be sent, and the UE can enter the LP-WUS listening period according to the third information.

[0222] Alternatively, after the UE activates UE monitoring of LP-WUS, the UE may enter the LP-WUS monitoring period when the timer expires. The timer may be used to determine the time when the UE enters the LP-WUS monitoring period. For example, the timer may be started when the UE turns on MR. When the timer expires, the UE may enter the LP-WUS monitoring period, or the UE may switch to WUR to monitor LP-WUS, or the UE may turn on WUR, etc.

[0223] Optionally, the UE does not immediately enter the LP-WUS listening period after the UE monitors that the LP-WUS is configured and / or activated, which can be regarded as a mechanism that can be turned on or off. For example, the network device can send a first indication message to the UE, and the first indication message can instruct the UE to enter the LP-WUS listening period after the UE monitors that the LP-WUS is activated; or, the first indication message can instruct the UE not to enter the LP-WUS listening period after the UE monitors that the LP-WUS is activated, or instruct the UE not to enter the LP-WUS listening period after the UE monitors that the LP-WUS is activated, or instruct the UE to keep monitoring the signal through the MR after the UE monitors that the LP-WUS is activated. For more information about this part, please refer to Figure 6 Related introduction of the embodiment shown.

[0224] Through the above mechanism, the UE can enter the LP-WUS listening period to meet the UE's monitoring requirements for the LP-WUS; and the UE does not need to enter the LP-WUS listening period immediately when the UE monitors the LP-WUS and is activated, to meet the UE's monitoring requirements on the MR.

[0225] The embodiments of the present application provide a mechanism for deactivating UE monitoring of LP-WUS. When UE monitoring of LP-WUS is deactivated, the embodiments of the present application also provide a method for handling a timer. For example, in addition to deactivating UE monitoring of LP-WUS, the UE can also stop and / or not start the timer, thereby not entering the LP-WUS monitoring period based on the timer, so that the state of the timer is consistent with the state of the UE monitoring of LP-WUS.

[0226] Each of the embodiments described above can be applied separately, or some or all of them can be applied in combination.
