Description

Technical Field

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

[0002] The user equipment (UE) is equipped with a main receiver (MR) or a main circuit (MR) or a main module for sending and receiving signals. The UE can work on the fifth generation (5G) new radio (NR) main link through the MR.

[0003] In order to further reduce power consumption, the UE can also use a circuit with low power consumption that is independent of the MR to receive signals. The circuit can be implemented by a circuit or chip with a relatively simple structure, and its power consumption is relatively low. Among them, the circuit is used to receive a wake-up signal (WUS) from a network device. The WUS received by the circuit is also called a low power wake-up signal (LP-WUS). When the UE detects the LP-WUS, the UE wakes up the MR that is turned off (or in sleep state) in the UE.

[0004] However, currently, the network device is not aware of the capabilities of the UE related to the circuit, which may cause the network device to be unable to send the LP-WUS to the UE, resulting in the UE being unable to achieve the purpose of reducing power consumption.

[0064] 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.

[0065] 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 three relationships may exist. 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" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c means: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, c can be single or multiple.

[0066] The ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the size, content, order, timing, priority or importance of multiple objects. For example, the first capability information and the second capability information can be the same capability information or different capability information, and this name does not indicate the difference in the sending end / receiving end, content, size, application scenario, priority or importance of the two capability information. In addition, the numbering of the steps in the various embodiments introduced in this application is only to distinguish different steps, and is not used to limit the order of the steps. For example, S301 may occur before S302, or may occur after S302, or may occur at the same time as S302.

[0067] Below, some terms or concepts in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0068] In the embodiment of the present application, the terminal device is a device with wireless transceiver function, 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 device (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 communications (device-to-device, D2D), vehicle to everything (vehicle to everything, V2X), machine-to-machine / machine-type communications (machine-to-machine / machine-type communications, M2M / MTC), Internet of Things (Internet of Things, IoT), virtual reality (virtual reality, VR), augmented reality (augmented reality, AR), industrial control (industrial control), self-driving, remote medical, smart grid (smart grid), smart furniture, smart office, smart wear, smart transportation, smart city (smart city), drones, robots and other scenarios of terminal devices. The terminal device may sometimes be referred to as UE, terminal, access station, UE station, remote station, wireless communication device, or user equipment, etc.

[0069] In the embodiment of the present application, the communication device for implementing the function of the terminal device 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 solution provided in the embodiment of the present application, the technical solution provided in the embodiment of the present application is described by taking the device for implementing the function of the terminal device as an example, and the terminal device is used as an example. In addition, for the convenience of description, the terminal device is described in the embodiment of the present application by taking the UE as an example.

[0070] The network equipment in the embodiment of the present application, for example, includes access network equipment, and / or core network equipment. The access network equipment is a device with wireless transceiver function, which is used to communicate with the terminal device. The access network equipment includes but is not limited to base stations (base transceiver station (BTS), Node B, evolved node B (eNodeB) / eNB, or next generation node B (gNodeB) / gNB), transceiver points (transmission reception point, TRP), base stations of subsequent evolution of the third generation partnership project (3rd 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 micro-micro base station, a small station, a relay station, etc. Multiple base stations can support networks with the same access technology, or 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 a 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 do not limit this. Taking the fifth generation mobile communication technology (5G) system as an example, the core network equipment includes: access and mobility management function (AMF), session management function (SMF), policy control function (PCF) or user plane function (UPF), etc.

[0071] In the CU-DU architecture, the 5G NR base station (gNB) is reconstructed into two logical network elements: the gNB central unit (gNB-CU) and the gNB distributed unit (gNB-DU). These two logical network elements can be deployed in one or separately according to the scenario and requirements. The following network architecture is referred to as the CU-DU separation architecture. The gNB-CU and gNB-DU are two functional entities, and the functional division is distinguished by the real-time nature of the processing content. For example, the gNB-CU includes the RRC, service data adaptation protocol (SDAP), and packet data convergence protocol (PDCP) in the gNB protocol stack, that is, the gNB-CU has the functions of the protocol layers such as RRC, SDAP, and PDCP. The gNB-DU includes the radio link control (RLC), medium access control (MAC), and physical layer (PHY) in the gNB protocol stack, that is, the gNB-DU has the functions of the protocol layers such as RLC, MAC, and PHY. Among them, the main function of the RRC layer is the high-level control plane of the UE, which is related to the access control, maintenance, release and configuration of the UE; the RRC layer can parse the RRC message; the main functions of the MAC layer and the PHY layer are the low-level scheduling of the UE, which are related to the data packetization and data scheduling of the UE; the MAC layer can parse the control signaling of the MAC layer; the PHY layer can parse the control signaling of the PHY layer.

[0072] In the embodiment of the present application, the communication device for realizing the function of the network device may be a network device, or may be a device capable of supporting the network device to realize the function, such as a chip system, which may be installed in the network device. In the technical solution provided in the embodiment of the present application, the technical solution provided in the embodiment of the present application is described by taking the device for realizing the function of the network device as an example that the network device is used as the device.

[0073] When the UE is in the radio resource control (RRC) idle state or the RRC inactive state, the position of the paging frame (PF) and the position of the paging occasion (PO) in a PF are calculated according to the UE identity number (ID) of the UE to receive the paging within the PO. Whether the UE performs the above-mentioned paging reception process in the RRC idle state or the RRC inactive state, or receives data in the RRC connected state, the same receiving module is used. In an embodiment of the present application, the receiver used to complete these functions (or perform related steps) is referred to as a main receiver (MR), or a main circuit (MR), or a main module, and the UE working in the main receiver, main circuit or main module can be working on the 5G NR main link. The process of UE receiving signals using the main receiver, main circuit or main module can be called the process of transmitting signals on a link (for example, called the NR main link, and this application does not limit the naming). The NR main link represents a connection relationship between the UE and the network device. It is a logical concept rather than a physical entity.

[0074] 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 receive the WUS from the network device, and the WUS received by the circuit A is also called LP-WUS. When the UE detects the LP-WUS, the UE wakes up the MR that is turned off (or in sleep state) in the UE. Circuit A can be called a wake-up circuit (wake up radio, WUR), or a wake-up receiver (wake up receiver, WUR), or a wake-up module, or a low-power circuit (lower-power radio, LR), or a low-power (lower-power receiver, LR) receiver, or a low-power module, or a low-power wake-up (LP-WUR) module. The UE using the circuit A to receive the wake-up signal can be called working on the WUR / LR link, or WUR / LR is in working state. The process of UE using circuit A to receive signals can be called the process of transmitting signals on a link (for example, called a WUR / LR main link, and the naming is not limited in the embodiments of the present application). The WUR / LR main link represents a connection relationship between the UE and the network device, which is a logical concept rather than a physical entity.

[0075] The wake-up signal can be used to wake up at least one UE or at least one group of UEs. As an example, the wake-up signal includes wake-up information, and the wake-up information represents information related to waking up the UE. Exemplarily, the wake-up information is information related to paging; the wake-up information can be used for the UE to determine whether to perform a paging reception process; or, the wake-up information can be used for the UE to determine whether to initiate random access. As an example, the wake-up information includes information (such as UE ID) of one or more UEs that need to be awakened. Among them, the one or more UEs may belong to at least one UE group (UE group), and accordingly, the wake-up information may include the group identifier of the UE group. Among them, when the access network device sends LP-WUS to the UE, in order to reduce the power consumption of circuit A, the LP-WUS signal may adopt some simple modulation methods such as on off keying (OOK) or Manchester OOK. Accordingly, circuit A in the UE can receive LP-WUS by envelope detection.

[0076] 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 searched, it can reside in 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 searched 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 searched, it can search for the LP-WUS according to the configuration information preset in the UE. If the LP-WUS can be searched and the signal quality of the LP-WUS is good, the UE can work in circuit A.

[0077] For reference Figure 1 , 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 LP-WUS after the low power circuit works, it can trigger the MR to be turned on to receive paging or initiate random access, etc. If the UE does not detect LP-WUS, it is not necessary to trigger the MR to be turned on, and the MR can continue to be turned off (or continue to sleep), thereby reducing the working time of the MR to save the power consumption of the UE.

[0078] However, currently, the base station is not aware of the relevant capabilities of the low-power circuit of the UE, which may cause the base station to be unable to send the LP-WUS to the UE, resulting in the UE being unable to achieve the purpose of reducing power consumption.

[0079] In view of this, the UE in the embodiment of the present application can send the first capability information to the first network device, and the first capability information can indicate whether the UE supports the first signal in at least one frequency unit, wherein the first signal is received by the UE through the low power module, that is, the first capability information is the relevant capability of the low power module of the UE. It can be seen that in the embodiment of the present application, the UE can inform the network device of the capability of the UE related to the low power module, so that the network device can send signals such as LP-WUS to the UE accordingly, so that the UE can work through the low power module to reduce the power consumption of the UE. In addition, from the perspective of hardware implementation, the UE may only support the first signal in certain frequency units, so the first capability information can indicate whether the UE supports the first signal in at least one frequency unit, so that the granularity of the capability reporting is finer, so that the network device can configure the UE normally, or the network device can communicate with the terminal device according to the capability of the UE.

[0080] The technical solution provided in the embodiment of the present application can be applied to the fourth generation mobile communication technology (the 4th generation, 4G) system, such as the long term evolution (long term evolution, LTE) system, or can be applied to the 5G system, such as the new radio (new radio, NR) system, or can also be applied to the next generation mobile communication system or other similar communication systems, such as the sixth generation mobile communication technology (the 6th generation, 6G) system, etc., without specific limitation. In addition, the technical solution provided in the embodiment of the present application can be applied to device-to-device D2D scenarios, such as NR-D2D scenarios, etc., or can be applied to V2X scenarios, such as NR-V2X scenarios, etc. For example, it can be used in factory manufacturing, whole-house intelligence, intelligent driving, assisted driving, or intelligent networked vehicles and other fields.

[0081] For reference Figure 2 , which is a communication network architecture applicable to the embodiments of the present application. Figure 2 It includes UE, access network equipment and core network equipment. The UE may be within the coverage of the access network equipment, or may be outside the coverage of the access network equipment. Figure 2 Take the case where the UE is within the coverage of the access network device as an example. The access network device is, for example, a base station. The core network device is, for example, an AMF or other device. The access network device is, for example, an overall architecture, or may also be a distributed architecture, for example, including gNB-CU and gNB-DU, etc., without limitation.

[0082] In order to better introduce the embodiments of the present application, the method provided by the embodiments of the present application is introduced below in conjunction with the accompanying drawings. In various embodiments of the present application, a frequency unit is, for example, a frequency band (band), or a frequency band combination (bandcombination, BC), or a frequency band in a frequency band combination, or a carrier in a frequency band in a frequency band combination, or a subcarrier (subcarrier), or a bandwidth part (bandwidth part, BWP), or a resource block (resource block, RB) set (set), etc. Among them, the frequency unit is, for example, a frequency unit corresponding to the NR system, that is, an NR frequency unit. In various embodiments of the present application, MR and a low-power module can be set in the UE, and the low-power module can also be referred to as a low-power unit, which can be implemented by software and / or hardware. The low-power module, for example, includes a wake-up circuit (wake up radio, WUR), a wake-up receiver (wake up receiver, WUR), a wake-up module, a low-power circuit (lower-power radio, LR), a low-power (lower-power receiver, LR) receiver, or a low-power wake-up (LP-WUR) module, etc. The following text takes the low-power module as an example of a low-power circuit to introduce the solution provided in the embodiment of the present application.

[0083] Unless otherwise specified in the following text, the steps indicated by dashed lines in the accompanying drawings corresponding to the various embodiments of the present application are all optional steps. The methods provided in the various embodiments of the present application can be applied to Figure 2 The network architecture shown, for example, the UE involved in each embodiment of the present application may be Figure 2 UE in; The first network device described in each embodiment of the present application may include a core network device and / or an access network device. In the following introduction, the first network device includes a first access network device as an example, that is, the "first access network device" in the following text may also be replaced by "first network device", and the first access network device may be Figure 2 The access network device in the embodiment of the present application may be Figure 2 The core network equipment in the network.

[0084] This application embodiment provides a communication method, see Figure 3 , which is a flow chart of the method.

[0085] S301. A UE sends a first message to a first access network device. Correspondingly, the first access network device receives the first message from the UE. Optionally, the UE may send the first message to the first access network device when in an RRC connected state, and the first access network device is, for example, a serving access network device of the UE.

[0086] The first message may include first capability information, and the first capability information may indicate whether the UE supports receiving the first signal in at least one frequency unit. The UE may receive the first signal through a low-power circuit, for example, the first signal is LP-WUS, or may be other signals that can be received through a low-power circuit. Whether the UE supports receiving the first signal in at least one frequency unit may also be understood as whether the low-power circuit of the UE can work, or whether the UE supports the low-power circuit. The information of the frequency unit in which the UE supports receiving the first signal may implicitly indicate that the UE supports receiving the first signal (or the UE supports the low-power circuit, or the low-power circuit of the UE can work), that is, by indicating whether the UE supports receiving the first signal in at least one frequency unit through the first capability information, it is possible to implicitly indicate whether the UE supports receiving the first signal. If the UE does not support receiving the first signal in any frequency unit, the UE does not support receiving the first signal; if the UE supports receiving the first signal, the UE should support receiving the first signal on at least one frequency unit.

[0087] At least one frequency unit may be all or part of the frequency units configured for the UE, or part or all of the frequency units supported by the UE, or part or all of the frequency units on which the UE can operate. Any of the at least one frequency unit may be currently activated or not activated. From a hardware implementation point of view, the UE may support receiving the first signal on certain frequency units, so the first capability information may indicate whether the UE supports receiving the first signal on at least one frequency unit, so that the granularity of capability reporting is finer, so that the access network device can configure the UE normally, or the access network device can communicate with the terminal device according to the capability of the UE. For example, at least one frequency unit includes all or part of the frequency units supported by the UE; or, at least one frequency unit includes all or part of the frequency units supported by the UE within a first frequency range, and the first frequency range is, for example, frequency range (FR) 1 (including frequency bands less than or equal to 6 GHz), or FR2 (including frequency bands greater than 6 GHz), or FR1 and FR2.

[0088] Optionally, the first capability information is capability information when the UE is in an RRC connected state.

[0089] Optionally, the first capability information is capability information when the UE is in an RRC non-connected state, such as capability information related to paging. In various embodiments of the present application, the RRC non-connected state includes, for example, an RRC idle state and / or an RRC inactive state.

[0090] Optionally, the first capability information may be capability information when the UE is in an RRC connected state, or capability information when the UE is in an RRC non-connected state. That is, the first capability information may be applied regardless of whether the UE is in an RRC connected state or an RRC non-connected state. The first capability information may indicate whether the UE supports receiving a first signal in at least one frequency unit when in an RRC connected state, or may indicate whether the UE supports receiving a first signal in at least one frequency unit when in an RRC non-connected state.

[0091] Alternatively, the first message includes first capability information A and first capability information B. The first capability information A may be capability information when the UE is in an RRC connected state, and the first capability information B may be capability information when the UE is in an RRC non-connected state. That is, when the UE is in an RRC connected state, the first capability information A is applied, and the first capability information A may indicate whether the UE supports receiving the first signal in at least one frequency unit when in the RRC connected state; when the UE is in an RRC non-connected state, the first capability information B is applied, and the first capability information B may indicate whether the UE supports receiving the first signal in at least one frequency unit when in the RRC non-connected state.

[0092] The first capability information indicates whether the UE supports receiving the first signal in at least one frequency unit, and there are multiple indication methods, which are introduced by example below. Among them, whether the first capability information is applicable to the UE in an RRC non-connected state or an RRC connected state, these indication methods are applicable, so the following takes the first capability information indicating whether the UE supports receiving the first signal in at least one frequency unit as an example, and does not distinguish the RRC state of the UE.

[0093] 1. Do not set a frequency unit dedicated to the low power circuit for the UE. Then the UE can work in the MR or the low power circuit on any frequency unit of at least one frequency unit, or consider deploying the first signal in the downlink frequency resource of the frequency unit supported by the UE.

[0094] 1. Assumption 1: If the UE supports receiving the first signal, then any frequency unit supported by the UE should support receiving the first signal, or any frequency unit supported by the UE should support receiving the first signal within the frequency unit. Taking the frequency unit as a frequency band as an example, if the UE supports the first signal, then any frequency band supported by the UE should support receiving the first signal, or any frequency band supported by the UE should support receiving the first signal within the frequency band (intra-band). Among them, any frequency unit supported by the UE may be any frequency unit within a certain frequency range supported by the UE, or any frequency unit within the entire frequency range supported by the UE. For example, the UE supports three frequency units, namely frequency units 1, 2 and 3. If the UE supports the first signal, then all three frequency units should support receiving the first signal, that is, any frequency unit of the three frequency units should support receiving the first signal; if the UE does not support receiving the first signal in any of the three frequency units, it is considered that the UE does not support receiving the first signal. Among them, the three frequency units may be all frequency units within a certain frequency range supported by the UE, or all frequency units within the entire frequency range supported by the UE.

[0095] Optionally, the first capability information may also indicate at least one frequency unit, for example, the first capability information includes an identifier of at least one frequency unit; or, the UE may also indicate at least one frequency unit to the first network device through other information; or, the frequency units supported by the UE may be configured by the first network device, so that the first network device can clearly identify which frequency units the at least one frequency unit includes without the need for further indication from the UE.

[0096] Under this assumption, the first capability information indicates whether the UE supports receiving the first signal in at least one frequency unit. An optional indication method is that if the value of the first capability information is the first value, it indicates that the UE supports receiving the first signal in at least one frequency unit, or indicates that any frequency unit in at least one frequency unit supports receiving the first signal; if the value of the first capability information is the second value or is not the first value, it indicates that the UE does not support receiving the first signal in at least one frequency unit, or indicates that the UE does not support receiving the first signal. For example, the first capability information is an indication field occupying 1 bit. If the value of the indication field is the first value, it indicates "support", and if the value of the indication field is the second value, it indicates "not supported". For example, the first value is "1" and the second value is "0".

[0097] Alternatively, the first capability information indicates whether the UE supports receiving the first signal in at least one frequency unit. Another optional indication method is that if the first capability information exists in the first message, or the first message includes the first capability information, it indicates that the UE supports receiving the first signal in at least one frequency unit, or indicates that any frequency unit in at least one frequency unit supports receiving the first signal; if the first capability information does not exist in the first message, or the first message does not include the first capability information, it indicates that the UE does not support receiving the first signal in at least one frequency unit, or indicates that the UE does not support receiving the first signal. For example, the first capability information occupies an indication field, and the indication field may occupy one or more bits. If the first message includes the indication field, it indicates "support", and if the first message does not include the indication field, it indicates "not supported".

[0098] In the above two indication methods, at least one frequency unit may include all frequency units supported by the UE (in this case, if the first capability information indicates that the UE supports receiving the first signal in at least one frequency unit, it indicates that any frequency unit of all frequency units supported by the UE supports receiving the first signal; if the first capability information indicates that the UE does not support receiving the first signal in at least one frequency unit or does not support receiving the first signal, it indicates that the UE does not support receiving the first signal in all frequency units supported by the UE); or, at least one frequency unit may include all or part of the frequency units supported by the UE within FR1 (in this case, if the first capability information indicates that the UE supports receiving the first signal in at least one frequency unit, it indicates that any frequency unit of all frequency units supported by the UE within FR1 supported by the UE units support receiving the first signal; if the first capability information indicates that the UE does not support receiving the first signal in at least one frequency unit or does not support receiving the first signal, it indicates that all frequency units in FR1 supported by the UE do not support receiving the first signal); or, at least one frequency unit may include all or part of the frequency units supported by the UE in FR2 (in this case, if the first capability information indicates that the UE supports receiving the first signal in at least one frequency unit, it indicates that any frequency unit in all frequency units in FR2 supported by the UE supports receiving the first signal; if the first capability information indicates that the UE does not support receiving the first signal in at least one frequency unit or does not support receiving the first signal, it indicates that all frequency units in FR2 supported by the UE do not support receiving the first signal). Alternatively, the first capability information may also indicate whether the UE supports receiving the first signal in FR1, and whether the UE supports receiving the first signal in FR2. For example, the first capability information indicates whether the UE supports receiving the first signal in at least one frequency unit. Another optional indication method is that the first capability information includes first sub-information and second sub-information. The first sub-information may indicate whether the UE supports receiving the first signal in M1 frequency units within the second frequency range, and the second sub-information may indicate whether the UE supports receiving the first signal in M2 frequency units within the third frequency range. M1 and M2 are both positive integers. For example, at least one frequency unit includes M1 frequency units and M2 frequency units. The M1 frequency unit is all or part of the frequency units supported by the UE in the second frequency range, and the M2 frequency unit is all or part of the frequency units supported by the UE in the third frequency range. Optionally, the second frequency range is, for example, FR1, and the third frequency range is, for example, FR2, or the second frequency range and the third frequency range may also be frequency ranges divided according to other frequency thresholds other than 6 GHz.

[0099] For example, if the value of the first sub-information is the first value, it indicates that the UE supports receiving the first signal in M1 frequency units, or indicates that any frequency unit in the M1 frequency units supports receiving the first signal; if the value of the first sub-information is the second value or is not the first value, it indicates that the UE does not support receiving the first signal in M1 frequency units, or indicates that the UE does not support receiving the first signal in FR1. Alternatively, if the first message includes the first sub-information, or the first sub-information exists in the first message, it indicates that the UE supports receiving the first signal in M1 frequency units, or indicates that any frequency unit in the M1 frequency units supports receiving the first signal; if the first message does not include the first sub-information, or the first sub-information does not exist in the first message, it indicates that the UE does not support receiving the first signal in M1 frequency units, or indicates that the UE does not support receiving the first signal in FR1.

[0100] Similarly, if the value of the second sub-information is the first value, it indicates that the UE supports receiving the first signal in all M2 frequency units, or indicates that any frequency unit in the M2 frequency units supports receiving the first signal; if the value of the second sub-information is the second value or is not the first value, it indicates that the UE does not support receiving the first signal in the M2 frequency units, or indicates that the UE does not support receiving the first signal in FR2. Alternatively, if the first message includes the second sub-information, or the second sub-information exists in the first message, it indicates that the UE supports receiving the first signal in all M2 frequency units, or indicates that any frequency unit in the M2 frequency units supports receiving the first signal; if the first message does not include the second sub-information, or the second sub-information does not exist in the first message, it indicates that the UE does not support receiving the first signal in the M2 frequency units, or indicates that the UE does not support receiving the first signal in FR2.

[0101] The first sub-information and the second sub-information may be indicated in the same manner, for example, both are indicated by taking values; or the first sub-information and the second sub-information may be indicated in different manners, for example, the first sub-information is indicated by taking values, and the second sub-information is indicated by whether it exists.

[0103] 2. Assumption 2: The UE supports receiving the first signal, which may be that some of the frequency units supported by the UE support receiving the first signal; or, as long as the UE supports receiving the first signal in some of the frequency units (or any frequency unit) supported by the UE, the UE is considered to support receiving the first signal. If the UE does not support receiving the first signal in any of the frequency units (or all of the frequency units) supported by the UE, the UE is considered to not support receiving the first signal. Among them, the partial frequency units supported by the UE may be partial frequency units within a certain frequency range (such as FR1 or FR2) supported by the UE, or partial frequency units within the entire frequency range supported by the UE. Taking the frequency unit as a frequency band as an example, as long as the UE supports receiving the first signal in some of the frequency bands supported by the UE, the UE is considered to support receiving the first signal. For example, the UE supports three frequency units, namely frequency units 1, 2 and 3, and as long as the UE supports receiving the first signal in any one or more of the three frequency units, the UE is considered to support receiving the first signal, for example, the UE supports receiving the first signal in frequency units 1 and 2; if the UE does not support receiving the first signal in any of the three frequency units, the UE is considered to not support receiving the first signal. The three frequency units may be all frequency units within a certain frequency range supported by the UE, or all frequency units within all frequency ranges supported by the UE.

[0104] Under this assumption, the first capability information indicates whether the UE supports receiving the first signal in at least one frequency unit, and may include one or more of the following: the first capability information includes a first list, the first list includes an identifier of at least one frequency unit, wherein the UE supports receiving the first signal in the frequency unit indicated by the identifier included in the first list, while the UE does not support receiving the first signal in the frequency unit indicated by the identifier not included in the first list; or, the first capability information includes at least one first indication information, at least one first indication information is included in the capability information of at least one frequency unit in the first message, any one of the first indication information is, for example, referred to as the first indication information A, and the first indication information A may indicate whether the UE supports receiving the first signal in the frequency unit corresponding to the first indication information A.

[0105] If the first capability information includes a first list, the first message indicates the UE's support for the first signal through the list. For the identifier included in the first list, the UE can support receiving the first signal in the frequency unit indicated by the identifier; and for the identifier not included in the first list, the UE does not support receiving the first signal in the frequency unit indicated by the identifier. The first access network device can determine in which frequency units the UE supports receiving the first signal according to the first list, and the indication method is relatively clear. Optionally, in this indication method, for the frequency unit indicated by any identifier in the first list, no matter which frequency unit combination (for example, frequency band combination) the frequency unit belongs to, the frequency unit can support receiving the first signal in the frequency unit combination where the frequency unit is located. For example, the first list includes identifier A, and identifier A indicates frequency unit A, and frequency unit A belongs to both frequency unit combination A supported by the UE and frequency unit combination B supported by the UE. When the UE works in frequency unit combination A, the frequency unit A of the UE in frequency unit combination A can support receiving the first signal; when the UE works in frequency unit combination B, the frequency unit A of the UE in frequency unit combination B can also support receiving the first signal.

[0106] If the first capability information includes at least one first indication information, the at least one first indication information corresponds to at least one frequency unit. The first message may include at least one capability information, and at least one capability information is capability information of at least one frequency unit. For example, the frequency unit is a frequency band, a frequency band combination, or a frequency band in a frequency band combination. For example, the frequency unit is a frequency band. For any first indication information 1 in at least one first indication information, the first indication information 1 indicates frequency band 1. Regardless of which frequency band combination or frequency band combinations the frequency band 1 belongs to, the frequency band 1 in the frequency band combination of the UE can support the reception of the first signal. For example, the first indication information 1 indicates frequency band 1, and frequency band 1 belongs to both frequency band combination 1 supported by the UE and frequency band combination 2 supported by the UE. When the UE operates in frequency band combination 1, the frequency band 1 in the frequency band combination 1 of the UE can support the reception of the first signal; when the UE operates in frequency band combination 2, the frequency band 1 in the frequency band combination 2 of the UE can also support the reception of the first signal.

[0107] For another example, the frequency unit is a frequency band combination. For any first indication information 1 in the at least one first indication information, the first indication information 1 may indicate frequency band combination 1, and the UE can support receiving the first signal in all frequency bands included in frequency band combination 1. For example, the first indication information 1 indicates frequency band combination 1 supported by the UE, and frequency band combination 1 includes frequency band 1 and frequency band 2. When the UE operates in frequency band 1 in frequency band combination 1, it can support receiving the first signal; when the UE operates in frequency band 2 in frequency band combination 1, it can also support receiving the first signal.

[0108] For another example, the frequency unit is a frequency unit in a frequency unit combination, such as a frequency band in a frequency band combination, and the at least one capability information may be the capability information of the frequency band included in the capability information of the frequency band combination. For example, the UE supports frequency band combination 1, and frequency band combination 1 includes frequency band 1 and frequency band 2. The capability information of the UE may include the capability information of frequency band combination 1, and the capability information of frequency band combination 1 includes the capability information of frequency band 1 and the capability information of frequency band 2. The UE supports receiving the first signal in frequency band 1 in frequency band combination 1. The at least one capability information in the embodiment of the present application may include the capability information of frequency band 1 in the capability information of frequency band combination 1. For example, the frequency band combination 1 supported by the UE includes frequency band 1 and frequency band 2, the first indication information 1 indicates frequency band 1 in frequency band combination 1, and the at least one first indication information does not indicate frequency band 2 in frequency band combination 1. Then, when the UE operates in frequency band 1 in frequency band combination 1, it can support receiving the first signal; and when the UE operates in frequency band 2 in frequency band combination 1, it does not support receiving the first signal.

[0109] Regardless of whether the frequency unit is a frequency band, a frequency band combination, or a frequency band in a frequency band combination, the indication method of the first indication information is similar. For example, for any first indication information 1 in at least one first indication information, the first indication information 1 may occupy a 1-bit indication field. If the value of the indication field is a first value, it indicates that the UE supports receiving the first signal in the frequency unit indicated by the first indication information 1; if the value of the indication field is a second value or is not the first value, it indicates that the UE does not support receiving the first signal in the frequency unit indicated by the first indication information 1. For example, the first value is "1" and the second value is "0". Alternatively, if the first indication information 1 exists in the first message, or at least one first indication information includes the first indication information 1, it indicates that the UE supports receiving the first signal in the frequency unit indicated by the first indication information; if the first indication information 1 does not exist in the first message, or at least one first indication information does not include the first indication information 1, it indicates that the UE does not support receiving the first signal in the frequency unit indicated by the first indication information.

[0110] 2. A frequency unit dedicated to a low-power circuit is set for the UE, which may be called a low-power frequency unit. In this way, at least one frequency unit may refer to at least one low-power frequency unit. The low-power frequency unit can be understood as a frequency unit in which the low-power circuit can work, or it can be understood that the UE can only work in a low-power circuit in a low-power frequency unit. In this case, the UE can support two types of frequency units, namely low-power frequency units and MR frequency units. The MR frequency unit can be understood as a frequency unit in which the MR can work, or it can be understood that the UE can only work in the MR in the MR frequency unit. Optionally, an additional index may be set for the low-power frequency unit. A low-power frequency unit may partially overlap or completely overlap with an MR frequency unit in the frequency domain, or there may be no intersection. For example, the UE supports three NR frequency units, namely, frequency unit 1 of 0-100MHz, frequency unit 2 of 100MHz-200MHz, and frequency unit 3 of 200MHz-300MHz. The frequency resources occupied by frequency unit 2 among these three frequency units can be used as a low-power frequency unit, which is numbered as low-power frequency unit 4. Then the UE supports three MR frequency units, namely, frequency unit 1, frequency unit 2 and frequency unit 3, and also supports one low-power frequency unit, which is low-power frequency unit 4. It can be seen that low-power frequency unit 4 completely overlaps with MR frequency unit 2 in the frequency domain. For another example, part of the frequency resources occupied by frequency unit 2 and part of the frequency resources occupied by frequency unit 3 in the above three frequency units can be combined into a low-power frequency unit, which is numbered as low-power frequency unit 4. Low-power frequency unit 4 occupies 150MHz to 250MHz. Then the UE supports three MR frequency units, namely frequency unit 1, frequency unit 2 and frequency unit 3, and also supports one low-power frequency unit, which is low-power frequency unit 4. It can be seen that low-power frequency unit 4 partially overlaps with MR frequency unit 2 and MR frequency unit 3 in the frequency domain. Among them, the bandwidth of the low-power frequency unit can be the same or different from the bandwidth of the MR frequency unit, the bandwidth of different MR frequency units can be the same or different, and the bandwidth of different low-power frequency units can be the same or different.

[0111] 1. Assumption 3: If the UE supports receiving the first signal, then any low-power frequency unit supported by the UE should support receiving the first signal, or any low-power frequency unit supported by the UE should support receiving the first signal within the low-power frequency unit. Taking the low-power frequency unit as a frequency band as an example, called a low-power frequency band, if the UE supports receiving the first signal, then any low-power frequency band supported by the UE should support receiving the first signal, or any low-power frequency band supported by the UE should support receiving the first signal within the low-power frequency band. Among them, any low-power frequency unit supported by the UE can be any low-power frequency unit within a certain frequency range (such as FR1 or FR2) supported by the UE, or any low-power frequency unit within the entire frequency range supported by the UE. For example, if the UE supports three low-power frequency units, namely low-power frequency units 1, 2 and 3, if the UE supports receiving the first signal, then all three low-power frequency units should support receiving the first signal, that is, any of the three low-power frequency units should support receiving the first signal; if the UE does not support receiving the first signal in any of the three low-power frequency units, then it is considered that the UE does not support receiving the first signal. Among them, the three low-power frequency units are all low-power frequency units within a certain frequency range supported by the UE, or all low-power frequency units within all frequency ranges supported by the UE.

[0112] Optionally, the first capability information may also indicate at least one low power consumption frequency unit, for example, the first capability information includes an identifier of at least one low power consumption frequency unit; or, the UE may also indicate at least one low power consumption frequency unit to the first network device through other information; or, the low power consumption frequency unit supported by the UE may be configured by the first network device or predefined by the protocol, so that the first network device can clearly know which frequency units the at least one low power consumption frequency unit includes without the need for further indication from the UE.

[0113] Under this assumption, the first capability information indicates whether the UE supports receiving the first signal in at least one frequency unit. An optional indication method is that if the value of the first capability information is the first value, it indicates that the UE supports receiving the first signal in at least one low-power frequency unit, or indicates that any low-power frequency unit in at least one low-power frequency unit supports receiving the first signal; if the value of the first capability information is the second value or is not the first value, it indicates that the UE does not support receiving the first signal in at least one low-power frequency unit, or indicates that the UE does not support receiving the first signal. Alternatively, the first capability information indicates whether the UE supports receiving the first signal in at least one frequency unit. Another optional indication method is that if the first capability information exists in the first message, or the first message includes the first capability information, it indicates that the UE supports receiving the first signal in at least one low-power frequency unit, or indicates that any low-power frequency unit in at least one low-power frequency unit supports receiving the first signal; if the first capability information does not exist in the first message, or the first message does not include the first capability information, it indicates that the UE does not support receiving the first signal in at least one low-power frequency unit, or indicates that the UE does not support receiving the first signal. For more introduction to this part of the content, please refer to the content corresponding to the assumption 1 above.

[0114] In the above two indication methods, at least one low-power consumption frequency unit may include all low-power consumption frequency units supported by the UE (at this time, if the first capability information indicates that the UE supports receiving the first signal in at least one frequency unit, it indicates that any low-power consumption frequency unit of all low-power consumption frequency units supported by the UE supports receiving the first signal; if the first capability information indicates that the UE does not support receiving the first signal in at least one frequency unit or does not support receiving the first signal, it indicates that the UE does not support receiving the first signal in all low-power consumption frequency units supported by the UE); or, at least one low-power consumption frequency unit may include all or part of the low-power consumption frequency units supported by the UE within FR1 (at this time, if the first capability information indicates that the UE supports receiving the first signal in at least one frequency unit, it indicates that any low-power consumption frequency unit of all low-power consumption frequency units supported by the UE within FR1 supported by the UE The first capability information indicates that the UE supports receiving the first signal in at least one frequency unit or does not support receiving the first signal, indicating that all low-power frequency units in FR1 supported by the UE do not support receiving the first signal); or, at least one low-power frequency unit may include all or part of the low-power frequency units supported by the UE in FR2 (in this case, if the first capability information indicates that the UE supports receiving the first signal in at least one frequency unit, it indicates that any frequency unit in all low-power frequency units in FR2 supported by the UE supports receiving the first signal; if the first capability information indicates that the UE does not support receiving the first signal in at least one frequency unit or does not support receiving the first signal, it indicates that all low-power frequency units in FR2 supported by the UE do not support receiving the first signal). Alternatively, the first capability information may also indicate whether the UE supports receiving the first signal in FR1, and whether the UE supports receiving the first signal in FR2. For example, the first capability information indicates whether the UE supports receiving the first signal in at least one frequency unit. Another optional indication method is that the first capability information includes first sub-information and second sub-information. The first sub-information may indicate whether the UE supports receiving the first signal in M1 low-power frequency units within FR1, and the second sub-information may indicate whether the UE supports receiving the first signal in M2 low-power frequency units within FR2. M1 and M2 are both positive integers. For example, at least one low-power frequency unit includes M1 low-power frequency units and M2 low-power frequency units. The M1 frequency unit is all or part of the low-power frequency units supported by the UE in FR1, and the M2 frequency unit is all or part of the low-power frequency units supported by the UE in FR2.

[0115] For example, if the value of the first sub-information is the first value, it indicates that the UE supports receiving the first signal in all M1 low-power frequency units, or indicates that any low-power frequency unit in the M1 low-power frequency units of the UE supports receiving the first signal; if the value of the first sub-information is the second value or is not the first value, it indicates that the UE does not support receiving the first signal in the M1 low-power frequency units, or indicates that the UE does not support receiving the first signal in FR1. Alternatively, if the first message includes the first sub-information, or the first sub-information exists in the first message, it indicates that the UE supports receiving the first signal in all M1 low-power frequency units, or indicates that any low-power frequency unit in the M1 low-power frequency units of the UE supports receiving the first signal; if the first message does not include the first sub-information, or the first sub-information does not exist in the first message, it indicates that the UE does not support receiving the first signal in the M1 low-power frequency units, or indicates that the UE does not support receiving the first signal in FR1.

[0116] Similarly, if the value of the second sub-information is the first value, it indicates that the UE supports receiving the first signal in all M2 low-power frequency units, or indicates that any low-power frequency unit among the M2 low-power frequency units of the UE supports receiving the first signal; if the value of the second sub-information is the second value or is not the first value, it indicates that the UE does not support receiving the first signal in the M2 low-power frequency units, or indicates that the UE does not support receiving the first signal in FR2. Alternatively, if the first message includes the second sub-information, or the second sub-information exists in the first message, it indicates that the UE supports receiving the first signal in all M2 low-power frequency units, or indicates that any low-power frequency unit among the M2 low-power frequency units of the UE supports receiving the first signal; if the first message does not include the second sub-information, or the second sub-information does not exist in the first message, it indicates that the UE does not support receiving the first signal in the M2 low-power frequency units, or indicates that the UE does not support receiving the first signal in FR2.

[0117] The first sub-information and the second sub-information may be indicated in the same manner, for example, both are indicated by taking values; or, the first sub-information and the second sub-information may be indicated in different manners, for example, the first sub-information is indicated by taking values, and the second sub-information is indicated by whether it exists.

[0118] 2. Assumption 4: The UE supports receiving the first signal, which may be that some of the low-power frequency units supported by the UE support receiving the first signal; or, as long as some of the low-power frequency units supported by the UE (or any low-power frequency unit) support receiving the first signal, the UE is considered to support the first signal. If the UE does not support receiving the first signal in any of the low-power frequency units supported by the UE, it is considered that the UE does not support receiving the first signal. Taking the low-power frequency unit as a low-power frequency band as an example, as long as the UE supports receiving the first signal in some of the low-power frequency bands supported by the UE, it is considered that the UE supports receiving the first signal. Among them, some of the low-power frequency units supported by the UE may be some low-power frequency units within a certain frequency range (such as FR1 or FR2) supported by the UE, or some low-power frequency units within the entire frequency range supported by the UE. For example, the UE supports three low-power frequency units, namely low-power frequency units 1, 2 and 3. As long as any one or more of the three low-power frequency units support receiving the first signal, the UE is considered to support receiving the first signal, for example, the UE supports receiving the first signal in low-power frequency units 1 and 2; if the UE does not support receiving the first signal in any of the three low-power frequency units, it is considered that the UE does not support receiving the first signal. Among them, the three low-power frequency units can be all low-power frequency units within a certain frequency range supported by the UE, or all low-power frequency units within all frequency ranges supported by the UE.

[0119] Under this assumption, the first capability information indicates whether the UE supports receiving the first signal in at least one frequency unit, and may include one or more of the following: the first capability information includes a first list, the first list includes an identifier of at least one low-power frequency unit, wherein the low-power frequency unit indicated by the identifier included in the first list supports receiving the first signal, while the frequency unit indicated by the identifier not included in the first list (including low-power frequency unit and / or MR frequency unit) does not support receiving the first signal; or, the first capability information includes at least one first indication information, at least one first indication information is included in the capability information of at least one frequency unit in the first message, any one of the first indication information is, for example, referred to as the first indication information A, and the first indication information A may indicate whether the UE supports receiving the first signal in the frequency unit corresponding to the first indication information A.

[0120] If the first capability information includes a first list, the first message indicates the UE's support for the first signal through the list. For the identifier included in the first list, the UE can support receiving the first signal in the low-power frequency unit indicated by the identifier; and for the identifier not included in the first list, the UE does not support receiving the first signal in the frequency unit indicated by the identifier. The first access network device can determine in which frequency units the UE supports receiving the first signal based on the first list, and the indication method is relatively clear. Optionally, the first list may correspond to a frequency unit combination, wherein the frequency unit combination may be a first type of frequency unit combination, and the frequency units included in the first type of frequency unit combination are all MR frequency units, so the first type of frequency unit combination may also be referred to as an MR frequency unit combination. For example, each MR frequency unit combination in some or all of the MR frequency unit combinations supported by the UE may correspond to a first list, and the identifiers included in the first list corresponding to different MR frequency unit combinations may be partially the same, completely the same, or completely different. Alternatively, there may be no corresponding relationship between the first list and the MR frequency unit combination.

[0121] Among them, if the first list corresponds to an MR frequency unit combination, then for the first list A corresponding to an MR frequency unit combination A, the low power consumption frequency unit indicated by any identifier in the first list A can be combined with the MR frequency unit combination A. Among them, the MR frequency unit combination A may include one or more MR frequency units. For example, the first list A includes identifier A, identifier A indicates low power consumption frequency unit A, the UE supports MR frequency unit combination A and MR frequency unit combination B, and MR frequency unit combination B does not have a corresponding first list. Then the low power consumption frequency unit A can be combined with MR frequency unit combination A, but cannot be combined with MR frequency unit combination B. Among them, if a low power consumption frequency unit can be combined with an MR frequency unit combination, it means that the UE can switch from the MR frequency unit included in the MR frequency unit combination to the low power consumption frequency unit, or can switch from the low power consumption frequency unit to the MR frequency unit included in the MR frequency unit combination; or, when the UE works in the MR frequency unit included in the MR frequency unit combination, it can measure the low power consumption frequency unit, or, when the UE works in the low power consumption frequency unit, it can measure the MR frequency unit included in the MR frequency unit combination.

[0122] For example, the first message includes the following content (taking the MR frequency unit combination as an MR frequency band combination as an example, the MR frequency band combination includes the MR frequency band. In addition, taking the low power consumption frequency unit combination as a low power consumption frequency band as an example):

[0123] MR BC list;

[0124] MR BC{A};

[0125] LP-WUS band list: band X, band Y, band Z;

[0126] MR BC{B},

[0127] LP-WUS band list: band X, band Y, band Z;

[0128] MR BC{A+B},

[0129] LP-WUS band list: band X, band Y.

[0130] Among them, LP-WUS band list represents the first list, and there is a corresponding first list for each of the three MR band combinations supported by the UE. Low power band X can be combined with MR band combination 1 (including MR band A), low power band Y can be combined with MR band combination 1, and low power band Z can also be combined with MR band combination 1; low power band X can be combined with MR band combination 2 (including MR band B), low power band Y can be combined with MR band combination 2, and low power band Z can also be combined with MR band combination 2; low power band Z can be combined with MR band combination 3 (including MR band A and MR band B), low power band Y can be combined with MR band combination 3, but low power band Z cannot be combined with MR band combination 3.

[0131] Alternatively, if the first list has no corresponding relationship with the MR frequency unit combination, the low power consumption frequency unit indicated by any identifier in the first list can be combined with any MR frequency unit combination (e.g., MR frequency band combination) supported by the UE. For example, the first list includes identifier A, identifier A indicates low power consumption frequency unit A, and the UE supports MR frequency unit combination A and MR frequency unit combination B. Then the low power consumption frequency unit A can be combined with either MR frequency unit combination A or MR frequency unit combination B.

[0132] For example, the first message includes the following content (taking the MR frequency unit combination as an MR frequency band combination as an example, the MR frequency band combination includes the MR frequency band. In addition, taking the low power consumption frequency unit combination as a low power consumption frequency band as an example):

[0133] LP-WUS band list: band X, band Y, band Z;

[0134] MR BC list: BC{A}, BC{B}, BC{A+B}, BC{A+C}.

[0135] Among them, LP-WUS band list represents the first list, and the first list includes the identifiers of the three low-power bands X, Y and Z. The UE supports four MR band combinations, one of which includes MR band A, another of which includes MR band B, another of which includes MR band A and MR band B, and another of which includes MR band A and MR band C. Then the low-power band X can be combined with any one or more of the four MR band combinations, the low-power band Y can be combined with any one or more of the four MR band combinations, and the low-power band Z can also be combined with any one or more of the four MR band combinations.

[0136] If the first capability information includes at least one first indication information, the at least one first indication information corresponds to at least one frequency unit one-to-one. Optionally, the frequency unit is, for example, a frequency band combination, for example, the first indication information is an index of the frequency band combination, or the first indication information includes the index of the frequency band combination and the index of the frequency band included in the frequency band combination. For example, the frequency unit combination mentioned above is a first type of frequency unit combination, or is called an MR frequency unit combination, and the frequency unit combination here can be understood as a second type of frequency unit combination. The first type of frequency unit combination may include an MR frequency unit but not a low-power frequency unit; the second type of frequency unit combination may include a low-power frequency unit, or include a low-power frequency unit and an MR frequency unit. For example, one or more low-power frequency units may be added to the MR frequency unit combination supported by the UE to form a second type of frequency unit combination. The first message may include at least one capability information, and at least one capability information is capability information of at least one frequency unit. For example, the frequency unit is a frequency band combination. For any first indication information 1 in at least one first indication information, the first indication information 1 indicates a frequency band combination 1. The frequency band combination 1 is a second type of frequency band combination. The frequency band combination 1 may include one or more low power consumption bands and one or more MR bands.

[0137] For example, the first message includes the following content:

[0138] BC list: BC{A+X}, BC{B+Y}, BC{A+B+X}, BC{A+C+Y}.

[0139] The BC list includes 4 first indication information, which indicate 4 second types of frequency band combinations, one of which includes MR band A and low power band X, another of which includes MR band B and low power band Y, another of which includes MR band A, MR band B and low power band X, and another of which includes MR band A, MR band C and low power band Y. For example, band combination 1 can be regarded as a band combination consisting of adding low power band X to the MR band combination including MR band A supported by the UE, and other band combinations can be understood similarly.

[0140] In addition to the above method, the first capability information may also indicate whether the UE supports receiving the first signal in at least one frequency unit in other ways, which is not limited.

[0141] Optionally, the first message may also include second capability information, and the second capability information may indicate capability information when the UE is in an RRC non-connected state. For example, when the first capability information indicates that the UE supports receiving the first signal in at least one frequency unit, or when the first capability information indicates that the UE supports receiving the first signal in at least one frequency unit when it is in an RRC non-connected state, the first message may also include the second capability information; and if the first capability information indicates that the UE does not support receiving the first signal in at least one frequency unit, or the first capability information indicates that the UE does not support receiving the first signal, or the first capability information indicates that the UE does not support receiving the first signal in at least one frequency unit when it is in an RRC non-connected state, or the first capability information indicates that the UE does not support receiving the first signal in an RRC non-connected state, then the first message may not need to include the second capability information. The second capability information may include N1 bandwidth information and / or K1 delay information, or the second capability information may also indicate other capability information related to low-power circuits when the UE is in an RRC non-connected state.

[0142] N1 is a positive integer, and N1 bandwidth information can indicate the bandwidth of at least one frequency unit. For example, N1 bandwidth information indicates N1 bandwidths, and the N1 bandwidths can be the bandwidth of at least one frequency unit. In at least one frequency unit, the bandwidths of different frequency units can be the same or different. Taking the frequency unit as a frequency band as an example, the bandwidth of a frequency band is, for example, 20MHz, 5MHz, or 1.4MHz. Optionally, N1 is equal to the number of at least one frequency unit, and the N1 bandwidths correspond to at least one frequency unit one-to-one. For example, the UE can report the corresponding bandwidth with the frequency unit or the frequency unit in the frequency unit combination as the granularity. Under this reporting granularity, the frequency unit and the bandwidth can correspond one-to-one. Alternatively, N1 can be less than the number of at least one frequency unit, and the bandwidth of one or more frequency units in at least one frequency unit can be one of the N1 bandwidths. For example, the UE may report the corresponding bandwidth with the UE or the frequency unit combination supported by the UE as the granularity. Under this reporting granularity, at least one frequency unit may correspond to one bandwidth (with the UE as the granularity), or one frequency unit combination may correspond to one bandwidth, and the bandwidth of all frequency units in the frequency unit combination is the bandwidth. For example, the UE supports frequency unit combination 1 and frequency unit combination 2, frequency unit combination 1 includes frequency unit 1 and frequency unit 2, frequency unit combination 2 includes frequency unit 3, the bandwidth of frequency unit 1 and frequency unit 2 are both bandwidth 1, and the bandwidth of frequency unit 3 is bandwidth 2. The UE reports the bandwidth with the frequency unit combination as the granularity, then N1 may be equal to 2, which are bandwidth 1 and bandwidth 2 respectively.

[0143] Optionally, the first capability information indicates whether the terminal device supports receiving the first signal in at least one frequency unit. An optional implementation is that the first capability information may include N1 bandwidth information, that is, by indicating N1 bandwidths, it can implicitly indicate whether the UE supports receiving the first signal in at least one frequency unit corresponding to the N1 bandwidths. Wherein, if N1=0, or the first capability information does not include N1 bandwidth information, or the first message does not include the first capability information, then the UE does not support receiving the first signal; if N1 is not equal to 0, or the first capability information includes N1 bandwidth information, then the UE should support receiving the first signal in at least one frequency unit. In this case, the first capability information may not have to be implemented in the aforementioned manner. For example, the first capability information may only include N1 bandwidth information, and the second capability information may not include N1 bandwidth information.

[0144] K1 is a positive integer, and K1 delays may correspond to at least one frequency unit. Each of the K1 delays may include one or more of the following: the time required for the UE to switch from the MR to the low-power circuit, the time required for the UE to switch from the low-power circuit to the MR, or the time required for the UE to switch between the low-power circuit and the MR. If a delay includes the time required for the UE to switch from the MR to the low-power circuit, or includes the time required for the UE to switch from the low-power circuit to the MR, it can be understood that the delay indicates the switching direction (i.e., from MR to the low-power circuit, or from the low-power circuit to the MR) in addition to indicating the time; and if a delay includes the time required for the UE to switch between the low-power circuit and the MR, it can be understood that the delay indicates the time but does not indicate the switching direction. In this indication mode, the UE uses the time indicated by the delay whether it switches from the low-power circuit to the MR or from the MR to the low-power circuit on the frequency unit corresponding to the delay. A delay is, for example, 0 nanoseconds (ns), 35 microseconds (us), 140us, or 210us. Among them, the embodiment of the present application may not need to deploy frequency units specifically for low-power circuits, that is, a frequency unit can support both MR and low-power circuits, or the UE can work in both MR and low-power circuits in a frequency unit. In this case, any one of the K1 delays may include the time required for the UE to switch from MR to low-power circuits on a frequency unit, or the time required for the UE to switch from low-power circuits to MR on a frequency unit, or the time required for the UE to switch between low-power circuits and MR on a frequency unit; or, the embodiment of the present application may also deploy frequency units for low-power circuits, which may be called low-power frequency units, as opposed to MR frequency units, for which reference may be made to the relevant introduction in the previous text. In this case, any one of the K1 delays may include the time required for the UE to switch from an MR of an MR frequency unit to a low-power circuit of a low-power frequency unit, or the time required for the UE to switch from a low-power circuit of a low-power frequency unit to an MR of an MR frequency unit, or the time required for the UE to switch between a low-power circuit of a low-power frequency unit and an MR of an MR frequency unit.

[0145] Optionally, the UE may report the delay with the granularity of UE, frequency unit, frequency unit combination, or frequency unit in the frequency unit combination. If the UE reports the delay with the granularity of UE, the frequency units supported by the UE all correspond to the same delay; if the UE reports the delay with the granularity of frequency unit or frequency unit in the frequency unit combination, the UE may report the delay for different supported frequency units separately, and the delays corresponding to different frequency units may be the same or different; if the UE reports the delay with the granularity of frequency unit combination, the UE may report the delay for different supported frequency unit combinations separately, and the delays corresponding to different frequency unit combinations may be the same or different. Alternatively, if a low-power frequency unit is configured for the UE, the UE may report the delay for each low-power frequency unit and the MR frequency unit corresponding to the low-power frequency unit. For example, according to the foregoing, if a low-power frequency unit can be combined with a frequency unit combination, the low-power frequency unit may have a corresponding relationship with all MR frequency units in the frequency unit combination. For example, a second type of frequency unit combination supported by the UE includes MR frequency unit A, MR frequency unit B and low power frequency unit X (or, the low power frequency unit X supported by the UE can be combined with MR frequency unit combination 1, and MR frequency unit combination 1 includes MR frequency unit A and MR frequency unit B), then the UE can report the delay corresponding to the frequency unit combination {A, X}, and can report the delay corresponding to the frequency unit combination {B, X}. Among them, the delay corresponding to the frequency unit combination {A, X} may include the time required for the UE to switch from the MR of frequency unit A to the low power circuit of frequency unit X, or include the time required to switch from the low power circuit of frequency unit X to the MR of frequency unit A, or include the switching time between the MR of frequency unit A and the low power circuit of frequency unit X.

[0146] In combination with the foregoing, the second capability information is the capability information of the UE in the RRC non-connected state, and the first capability information also includes the capability information of the UE in the RRC non-connected state. It can be understood that the capability information of the UE in the RRC non-connected state includes one or more of the following: information used to indicate whether the UE supports the first signal in at least one frequency unit, N1 bandwidth information, or K1 delay information.

[0147] The first message includes, for example, a first container, which can be used to carry information related to the UE and paging. The first container is, for example, UE radio paging information, or the first container may have other names, which is not limited in the embodiment of the present application. The first container is UE radio paging information as an example. Optionally, the first capability information and / or the second capability information included in the first message may not be included in the UE radio paging information. That is, the first message may include a first capability information and / or a second capability information, which is included in the first message but not included in the UE radio paging information. Alternatively, the UE radio paging information container in the first message may include the first capability information and / or the second capability information. In this case, optionally, the first message may include two first capability information and / or two second capability information, one of which may be included in the UE radio paging information, and the other of which may be included in the UE radio paging information.

[0148] Optionally, the first message may further include third capability information, and the third capability information may indicate capability information when the UE is in an RRC connected state. For example, when the first capability information indicates that the UE supports receiving the first signal in at least one frequency unit, or when the first capability information indicates that the UE supports receiving the first signal in at least one frequency unit when it is in an RRC connected state, the first message may further include the third capability information; and if the first capability information indicates that the UE does not support receiving the first signal in at least one frequency unit, or the first capability information indicates that the UE does not support receiving the first signal, or the first capability information indicates that the UE does not support receiving the first signal in at least one frequency unit when it is in an RRC connected state, or the first capability information indicates that the UE does not support receiving the first signal in an RRC connected state, then the first message may not need to include the third capability information. The third capability information may include one or more of the following: N2 bandwidth information, K2 delay information, time division multiplexing (TDM) information, or measurement interval (gap) information. Alternatively, the third capability information may also include other capability information related to low-power circuits when the UE is in an RRC connected state.

[0149] For the introduction of N2 bandwidth information, please refer to the introduction of N1 bandwidth information in the previous article. For the introduction of K2 delay information, please refer to the introduction of K1 delay information in the previous article.

[0150] The TDM information may indicate whether the UE operates in the MR and low-power circuits in a time-division manner. For example, if the UE's radio frequency capability can support the UE to operate in the MR and low-power circuits at the same time, the UE does not need to use the TDM method, but can operate in the MR and low-power circuits at the same time; or, if the UE's radio frequency capability cannot support the UE to operate in the MR and low-power circuits at the same time, the UE can operate in the MR and low-power circuits in a TDM manner. Optionally, the TDM information may indicate whether the UE receives in the MR and low-power circuits in a time-division manner. For example, if the UE's radio frequency capability can support the UE to receive in the MR and low-power circuits at the same time, the UE does not need to use the TDM method, but can operate in the MR and low-power circuits at the same time; or, if the UE's radio frequency capability cannot support the UE to receive in the MR and low-power circuits at the same time, the UE can use the TDM method to receive in the MR and low-power circuits.

[0151] Optionally, the UE may report TDM information with the granularity of UE, frequency unit, frequency unit combination, or frequency unit in the frequency unit combination. For example, one TDM information may occupy a 1-bit indication field. If the indication field indicates that TDM is required between the low-power circuit and the MR, it means that the low-power circuit and the MR cannot work at the same time. If the indication field indicates that TDM is not required between the low-power circuit and the MR, it means that the low-power circuit and the MR can work at the same time.

[0152] Optionally, the third capability information may not include TDM information, but may implicitly indicate whether the UE needs TDM through delay information. For example, if a delay is 0, it means that TDM is not required between the low-power circuit corresponding to the delay and the MR, and if a delay is greater than 0, it means that TDM is required between the low-power circuit corresponding to the delay and the MR.

[0153] The measurement interval information may indicate whether the UE needs to perform measurements in the low-power circuit during the measurement interval in the MR, and / or whether the UE needs to perform measurements in the low-power circuit during the measurement interval in the MR. For example, if the UE's radio frequency capability can support the UE to work in both the MR and the low-power circuit at the same time, the UE can measure the low-power circuit without switching the frequency when working in the MR. Similarly, the MR can be measured without switching the frequency when working in the low-power circuit, so there is no need to set the measurement interval; or, if the UE's radio frequency capability cannot support the UE to work in both the MR and the low-power circuit at the same time, and the UE may need to measure the low-power circuit when working in the MR, and / or may need to measure the MR when working in the low-power circuit, the UE can use the measurement interval to achieve the measurement.

[0154] Optionally, the UE may report the measurement interval information with the granularity of UE, frequency unit, frequency unit combination, or frequency unit in the frequency unit combination. For example, one measurement interval information may occupy a 1-bit indication field. If the indication field indicates that a measurement interval is required between the low-power circuit and the MR, it means that the measurement interval needs to be configured when measuring the MR in the low-power circuit and / or when measuring the low-power circuit in the MR. If the indication field indicates that no measurement interval is required between the low-power circuit and the MR, it means that no measurement interval needs to be configured when measuring the MR in the low-power circuit and / or when measuring the low-power circuit in the MR.

[0155] Optionally, the third capability information may not include measurement interval information, but may implicitly indicate whether the UE needs a measurement interval through delay information. For example, if a delay is 0, it means that no measurement interval is required between the low-power circuit corresponding to the delay and the MR, and if a delay is greater than 0, it means that a measurement interval is required between the low-power circuit corresponding to the delay and the MR.

[0156] In combination with the foregoing, the third capability information is the capability information of the UE in the RRC connected state, and the first capability information also includes the capability information of the UE in the RRC connected state. It can be understood that the capability information of the UE in the RRC connected state includes one or more of the following: information used to indicate whether the UE supports the first signal in at least one frequency unit, N2 bandwidth information, K2 delay information, TDM information, or measurement interval information.

[0157] Optionally, the first message may include one or more of the first capability information, the second capability information, or the third capability information. The foregoing takes the example that the UE sends the capability information of the UE in the RRC connected state and the capability information of the UE in the RRC non-connected state through one message (the first message), or the UE may also send the capability information of the UE in the RRC connected state and the capability information of the UE in the RRC non-connected state through different messages. For example, the first message includes message A and message B, message A includes the capability information of the UE in the RRC non-connected state, for example, the first capability information and / or the second capability information, wherein the first capability information indicates whether the UE supports receiving the first signal in at least one frequency unit when in the RRC non-connected state; message B includes the capability information of the UE in the RRC connected state, for example, the first capability information and / or the third capability information, wherein the first capability information indicates whether the UE supports receiving the first signal in at least one frequency unit when in the RRC connected state. Message A and message B may be sent simultaneously, or may be sent at different times.

[0158] In addition to the capability information above, the first message may also include other capability information of the UE, such as capability information of the UE under one or more radio access technologies (radio access technology, RAT), etc., without limitation. RAT includes, for example, new NR, and / or evolved-UMTS terrestrial radio access technology (evolved-UMTS terrestrial radio access, E-UTRA), or, E-UTRA-NR technology, etc. Optionally, the first message is, for example, a UE capability information message, or may be other messages.

[0159] Optionally, before S301, the method may further include S302, the first access network device sends a request message, and accordingly, the UE receives the request message from the first access network device. The request message may request the wireless access capability of the UE, and after receiving the request message, the UE may send a first message to the first access network device. The request message is, for example, a UE capability enquiry message, or may be other messages. For example, the request message may carry a RAT-type indication, and the RAT-type indication may include the RAT corresponding to the capability that the first access network device requests the UE to report. Among them, the first capability information, the second capability information, the third capability information, etc. involved in the embodiment of the present application may be capability information corresponding to the NR. Optionally, the request message may also carry filtering information for filtering the capabilities of the UE. The filtering information may also be understood as conditional information, and the UE may only send capability information that meets the filtering information to the first access network device.

[0160] Optionally, before S301 or before S302, the first access network device may further send system information (SI), where the system information may indicate whether the cell where the UE is located supports sending and / or configuring the first signal. If the system information indicates that the cell supports sending and / or configuring the first signal, the system information may further indicate the relevant configuration of the first signal. Among them, if the cell supports sending and / or configuring the first signal, and the UE also supports receiving the first signal, the UE can use a low-power circuit to receive the first signal; when the first access network device pages the UE, it can determine whether to use the first signal to wake up the UE based on the capability information of the UE indicated by the paging message (for example, one or more of the first capability information, the second capability information or the third capability information). For example, if the cell supports sending and / or configuring the first signal, and the UE also supports receiving the first signal, the first access network device can use the first signal to wake up the UE and then page the UE; if the cell does not support sending and / or configuring the first signal and / or the UE does not support receiving the first signal, the first access network device may not use the first signal to wake up the UE, but may use other signals (such as WUS, etc.) to wake up the UE.

[0161] Optionally, after S301, the method may further include S303, the first access network device sends a second message to the core network device, and accordingly, the core network device receives the second message from the first access network device. The core network device is, for example, an AMF, or may also be other devices. The second message may include the fourth capability information of the UE. Optionally, if the UE wireless paging information (first container) in the first message includes the first capability information and / or the second capability information, the first access network device may add the UE wireless paging information to the second message, at which time the fourth capability information may include the first capability information and / or the second capability information in the UE wireless paging information, and optionally, the fourth capability information is the UE wireless paging information. Alternatively, if the first message includes the first capability information and / or the second capability information, but the first capability information and / or the second capability information are not included in the UE wireless paging information in the first message, the first access network device may determine the fourth capability information based on the first capability information and / or the second capability information outside the UE wireless paging information. For example, the first access network device may parse or derive the first capability information and / or the second capability information from the information outside the UE radio paging information container in the first message, encode the obtained first capability information and / or the second capability information, and add the encoded first capability information and / or the second capability information as the fourth capability information to the second message. Optionally, the second message is, for example, a UE radio paging information message.

[0162] The paging method for the UE includes core network (CN) paging and RAN paging. For example, CN paging can be used for UE in RRC idle state, and RAN paging can be used for UE in RRC inactive state. For CN paging, optionally, the method may also include S304, and S304 occurs after S303, for example. S304 may include that the core network device sends a third message to the first access network device, and correspondingly, the first access network device receives the third message from the core network device. The third message may include information of the UE to be paged, such as an identifier of the UE to be paged, and may include capability information of the UE to be paged. For example, if the UE to be paged includes the UE, the third message may include the identifier of the UE, and include fourth capability information. The first access network device receives the third message, and then it can determine which method should be used to page the UE to be paged. For example, the third message includes the identifier of the UE and the fourth capability information. The first access network device can determine whether the UE supports receiving the first signal in at least one frequency unit according to the fourth capability information to determine the paging method or wake-up method for the UE. Optionally, the method may further include S305, the first access network device sends a first signal, and the first signal can be used to wake up one or more UEs, including the one or more UEs. For example, the UE receives the first signal through a low-power circuit, and the UE can receive subsequent paging messages based on the first signal. For example, after receiving the first signal, the low-power circuit can wake up the MR of the UE. For example, if the UE supports receiving the first signal in at least one frequency unit, and the cell where the UE is located supports sending and / or configuring the first signal, S305 can be executed. Optionally, the method may further include S306, for example, occurring after S305. In S306, the first access network device sends a first paging message, and the UE receives the first paging message from the first access network device through the MR. The first paging message can be used to page at least one UE, including the UE. The UE awakened by the first signal and the UE paged by the first paging message can be completely the same or partially the same.

[0163] Alternatively, if the UE does not support receiving the first signal in at least one frequency unit, and / or the cell where the UE is located does not support sending and / or configuring the first signal, the first access network device may use other methods to wake up the UE, such as waking up the UE through WUS. Then S305 can be replaced by the first access network device sending WUS, and the WUS can be used to wake up one or more UEs, including the one or more UEs. For example, if the UE receives WUS through MR, the low-power circuit can wake up the MR of the UE. At this time, the method may also include S306, the first access network device sends a first paging message, and the UE receives the first paging message from the first access network device through MR. The first paging message can be used to page at least one UE, including the UE, and the UE awakened by the WUS and the UE paged by the first paging message can be exactly the same or partially the same. For another example, the first access network device can directly send the first paging message, then S305 is not executed. At this time, the method may include S306, the first access network device sends the first paging message, the UE receives the first paging message from the first access network device through the MR, and the first paging message can be used to page at least one UE, and the at least one UE includes the UE.

[0164] Optionally, the third message is, for example, a paging message, which may include a paging-related UE paging radio capability information (UE radio capability for paging) field, and the fourth capability information may be included in the UE radiocapability for paging field, or the UE radio capability for paging field includes a second message (for example, a UE radio paging information (UE Radio Paging Information) message), and the second message includes the fourth capability information.

[0165] For RAN paging, the method may also include S304, and the third message may include fourth capability information. For example, the core network device stores registration information of one or more UEs, and the registration information of the UE may include capability information of the UE, then the core network device may send all or part of the stored capability information of the UE to the corresponding access network device. At this time, the third message is, for example, core network assistance information for RRC inactive, for example, the core network assistance information for RRC inactive includes UE radio capability for paging, and the fourth capability information may be included in the UE radio capability for paging. For RAN paging, the UE to be paged is determined by the access network device. For example, if the first access network device receives the fourth capability information, the first access network device may also determine whether the UE supports receiving the first signal in at least one frequency unit according to the fourth capability information to determine the paging method or wake-up method for the UE. Optionally, the method may also include S305, the first access network device sends a first signal, and the first signal may be used to wake up one or more UEs, including the UE. For example, the UE receives the first signal through a low-power circuit, and the UE may receive subsequent paging messages according to the first signal. For example, after receiving the first signal, the low-power circuit can wake up the MR of the UE. For example, if the UE supports receiving the first signal in at least one frequency unit, and the cell where the UE is located supports sending and / or configuring the first signal, S305 can be executed. Optionally, the method may also include S306, which occurs after S305. In S306, the first access network device sends a first paging message, and the UE receives the first paging message from the first access network device through the MR. The first paging message can be used to page at least one UE, and the at least one UE includes the UE. The UE awakened by the first signal and the UE paged by the first paging message can be exactly the same or partially the same.

[0166] Alternatively, if the UE does not support receiving the first signal in at least one frequency unit, and / or the cell where the UE is located does not support sending and / or configuring the first signal, the first access network device may use other methods to wake up the UE, such as waking up the UE through WUS. Then S305 can be replaced by the first access network device sending WUS, and the WUS can be used to wake up one or more UEs, including the one or more UEs. For example, if the UE receives WUS through MR, the low-power circuit can wake up the MR of the UE. At this time, the method may also include S306, the first access network device sends a first paging message, and the UE receives the first paging message from the first access network device through MR. The first paging message can be used to page at least one UE, including the UE, and the UE awakened by the WUS and the UE paged by the first paging message can be exactly the same or partially the same. For another example, the first access network device may directly send the first paging message, then S305 is not executed. In this case, the method may include S306, the first access network device sends the first paging message, the UE receives the first paging message from the first access network device through the MR, and the first paging message can be used to page at least one UE, and the at least one UE includes the UE.

[0167] Optionally, if the UE is not currently within the coverage of the first access network device, for example, the first access network device is the anchor access network device of the UE, but the UE has currently moved to the coverage of other access network devices, then the first access network device can not only page the UE itself, but also send a fourth message to at least one access network device, and this step occurs, for example, after S304. The fourth message may include information of the UE to be paged, such as an identifier of the UE to be paged, and capability information of the UE to be paged. For example, if the UE to be paged includes the UE, the fourth message may include the identifier of the UE, and fourth capability information. For the access network device that receives the fourth message, the paging method or wake-up method for the UE can be determined based on the fourth capability information, thereby paging the UE. For related content, please refer to the previous text.

[0168] Optionally, the fourth message is, for example, a paging message, which may include a UE radio capability for paging field, and the fourth capability information may be included in the UE radio capability for paging field, or the UE radio capability for paging field includes a second message (for example, a UE radio paging information (UE RadioPaging Information) message), and the second message includes the fourth capability information.

[0169] Optionally, S303 to S306 are mainly for the first capability information and / or the second capability information which is capability information when the UE is in an RRC non-connected state.

[0170] The UE in the embodiment of the present application can send the first capability information to the first access network device, and the first capability information can indicate whether the UE supports the first signal in at least one frequency unit, wherein the first signal is received by the UE through the low-power circuit, that is, the first capability information is the relevant capability of the low-power circuit of the UE. It can be seen that in the embodiment of the present application, the UE can inform the access network device of the capability of the UE related to the low-power circuit, so that the access network device can send signals such as LP-WUS to the UE accordingly, so that the UE can work through the low-power circuit to reduce the power consumption of the UE. In addition, from the perspective of hardware implementation, the UE may only support the first signal in certain frequency units, so the first capability information can indicate whether the UE supports the first signal in at least one frequency unit, so that the granularity of the capability reporting is finer, so that the access network device can configure the UE normally, or the access network device can communicate with the terminal device according to the capability of the UE.

[0171] exist Figure 3 In the embodiment shown, the access network device is an integrated architecture as an example. The access network device may also be implemented through a CU-DU architecture. For this reason, the embodiment of the present application provides another communication method to introduce how the access network device of the CU-DU architecture pages the UE. Please refer to Figure 4 , which is a flow chart of the method.

[0172] S401. A centralized unit (e.g., gNB-CU) of an access network device sends second indication information to a distributed unit (e.g., gNB-DU) of the access network device. Correspondingly, the distributed unit receives the second indication information from the centralized unit.

[0173] In the CU-DU architecture, the centralized unit receives paging messages from core network devices or other access network devices, or receives UE capability information (e.g. Figure 3 The fourth capability information of the embodiment shown in the figure) is sent to the UE by the distribution unit, so the distribution unit should also learn the fourth capability information to determine which paging method to use for the UE. Figure 4 The embodiment shown is Figure 3 The embodiments shown can be combined, then Figure 4 The first access network device described in the embodiment shown is Figure 3 The first access network device described in the embodiment shown may be the same device. Figure 3In the illustrated embodiment, among the steps performed by the first access network device, the step of sending the first paging message by the first access network device can be performed by the distributed unit of the embodiment of the present application, and all other steps performed by the first access network device can be performed by the centralized unit of the embodiment of the present application. For example, S401 can occur after S304. Or, Figure 4 The access network device described in the embodiment shown in the figure is Figure 3 Any one of the at least one access network devices described in the illustrated embodiment may be the same device, and the access network device may receive a fourth message from the first access network device, which may be executed by the centralized unit, and the access network device may send a paging message for paging the UE, which may be executed by the distributed unit.

[0174] or, Figure 4 The embodiment shown is Figure 3 The illustrated embodiments may also be used separately without being combined. Then, before S401, the centralized unit may determine to page the UE, for example, the centralized unit receives a paging message from a core network device for paging the UE, or the centralized unit determines to page the UE on its own (RAN paging method).

[0175] For example, the centralized unit obtains the fourth capability information of the UE, or obtains one or more of the first capability information, the second capability information, or the third capability information of the UE. For an introduction to these capability information, please refer to Figure 3 The embodiment shown. The centralized unit can determine whether the UE supports receiving the first signal, or whether the UE supports receiving the first signal in at least one frequency unit, or which paging method or wake-up method should be adopted for the UE (for example, waking up by the first signal, or waking up by other signals, or directly sending a paging message) according to the obtained capability information. Then the centralized unit can send a second indication information to the distributed unit, and the second indication information can indicate the information of the UE to be paged. For example, the UE to be paged includes the UE, and the information of the UE indicated by the second indication information can indicate whether the UE supports receiving the first signal (or whether the UE has enabled the first signal, or whether the UE uses the first signal), or whether the UE supports receiving the first signal in at least one frequency unit, or the paging method or wake-up method adopted for the UE.

[0176] Optionally, the second indication information may be included in a second paging message, and the second paging message corresponds to the UE. For example, if two UEs need to be paged, two second paging messages need to be sent, corresponding to the paging of the two UEs respectively.

[0177] The second paging message may include a UE paging capability field, for example, the second indication information may be included in the UE paging capability field. At this time, the second indication information may indicate whether the UE supports receiving the first signal in at least one frequency unit, or the second indication information includes one or more of the first capability information, the second capability information, or the third capability information. For the indication method of the second indication information, and the content related to these capability information, etc., please refer to Figure 3 Optionally, the second indication information is, for example, a second message (for example, a UE radio paging information message), and the second message is included in the UE paging capability field.

[0178] Alternatively, the second paging message may include a paging cell list, which may include information of one or more cells, and the second indication information may be included in the information of the cells in the paging cell list. For example, if the paging cell list includes information of a first cell, which is a cell where the UE resides, the second indication information may be included in the information of the first cell. At this time, the second indication information may indicate whether the UE supports receiving the first signal when the first cell pages the UE. For example, the second indication information may occupy a 1-bit indication field, and if the value of the indication field is a first value, it indicates "support", that is, it indicates that the first signal is supported, or it indicates that the first signal is used to wake up; if the value of the indication field is a second value or is not the first value, it indicates "not supported", that is, it indicates that the first signal is not supported. The first value is, for example, "1", and the second value is, for example, "0". Alternatively, if the indication field exists in the second paging message, it indicates "support", that is, it indicates that the first signal is supported, or it indicates that the first signal is used to wake up; if the indication field does not exist in the second paging message, it indicates "not supported", that is, it indicates that the first signal is not supported.

[0179] After receiving the second indication information, the distribution unit can directly clarify whether the UE to be paged supports receiving the first signal, or whether the UE supports receiving the first signal in at least one frequency unit, or which paging method or wake-up method should be used for the UE, so that the distribution unit can page the UE in a corresponding paging method, or wake up the UE in a corresponding wake-up method. Optionally, the method also includes S402, where the distribution unit sends a first signal. For example, if the UE supports receiving the first signal, or supports receiving the first signal in at least one frequency unit, or the second indication information indicates that the UE is paged or woken up by the first signal, S402 can be executed. The first signal can be used to wake up one or more UEs, including the UE. For example, the UE receives the first signal through a low-power circuit, and the UE can receive subsequent paging messages according to the first signal. For example, after receiving the first signal, the low-power circuit can wake up the MR of the UE. Optionally, the method also includes S403, which can occur after S402. In S403, the distribution unit sends a first paging message, and the UE receives the first paging message from the distribution unit through the MR. The first paging message can be used to page at least one UE, and the at least one UE includes the UE. The UE awakened by the first signal and the UE paged by the first paging message can be completely the same or partially the same. Alternatively, if the UE does not support receiving the first signal, or does not support receiving the first signal in at least one frequency unit, or the second indication information indicates that the first signal (or WUS) is not used to page or wake up the UE, the distribution unit can wake up the UE in other ways, such as waking up the UE through the WUS, or directly sending a paging message. Then S402 can be replaced by the distribution unit sending a WUS, and the WUS can be used to wake up one or more UEs, and the one or more UEs include the UE. For example, if the UE receives a WUS through the MR, the low-power circuit can wake up the MR of the UE. At this time, the method may also include S403, the distribution unit sends a first paging message, the UE receives the first paging message from the distribution unit through the MR, the first paging message can be used to page at least one UE, the at least one UE includes the UE, the UE awakened by the WUS and the UE paged by the first paging message can be completely the same or partially the same. For another example, the distribution unit can directly send the first paging message, then S402 is not executed, at this time the method may include S403, the distribution unit sends the first paging message, the UE receives the first paging message from the distribution unit through the MR, the first paging message can be used to page at least one UE, the at least one UE includes the UE.

[0180] Among them, if the embodiment of the present application is Figure 3 In combination with the embodiments shown, Figure 3The step of sending the first signal or WUS by the first access network device in the embodiment shown is specifically the step of sending the first signal or WUS by the distribution unit in the embodiment of the present application; Figure 3 The step of the first access network device sending the first paging message in the illustrated embodiment is specifically the step of the distribution unit sending the first paging message in the embodiment of the present application.

[0181] Optionally, if the second indication information indicates whether the UE supports receiving the first signal in at least one frequency unit, S401 may also be replaced by the centralized unit sending the information of the UE to be paged to the distributed unit. Accordingly, the distributed unit receives the information of the UE to be paged from the centralized unit. The information of the UE to be paged includes, for example, the low-power circuit-related capability information of the UE to be paged. For example, if the UE to be paged includes the UE, the information of the UE to be paged may include the fourth capability information, or include one or more of the first capability information, the second capability information, or the third capability information. It can be understood that the second indication information indicates whether the UE supports receiving the first signal in at least one frequency unit. One indication method is that the second indication information includes the fourth capability information; or another indication method is that the second indication information includes one or more of the first capability information, the second capability information, or the third capability information.

[0182] In this way, the distribution unit can determine whether the UE to be paged supports receiving the first signal based on the received capability information, or determine whether the UE to be paged supports receiving the first signal in at least one frequency unit, thereby determining the paging method or wake-up method to be adopted. For example, for the UE, the distribution unit can determine whether the UE supports receiving the first signal based on the received capability information, or determine whether the UE supports receiving the first signal in at least one frequency unit, thereby adopting a corresponding method to page or wake up the UE. For the paging or wake-up process, please refer to the above.
