A communication method and apparatus

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202410930877.4, filed on July 11, 2024, entitled "A Communication Method and Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of communication technology, and in particular to a communication method and apparatus. Background Technology

[0004] In 5G new radio (NR) systems, user equipment (UE) performs radio resource management (RRM) measurements of the serving cell and neighbor cells when in the radio resource control (RRC) idle or inactive state. Based on the measurement results, the UE can decide whether to stay in the current serving cell or perform cell reselection to ensure that the UE can camp on a cell with better channel quality.

[0005] On the other hand, to reduce the power consumption of user equipment (UE), the UE can use a separate low-power circuit to receive signals, such as a low-power wake-up signal (LP-WUS). This low-power circuit can be implemented using simple circuits or chips with low power consumption. This low-power circuit can be called a wake-up radio (WUR), a wake-up receiver (WUR), a wake-up circuit, a low-power radio (LR), or a wake-up receiver module, etc. However, during cell reselection, the UE may reselect to a cell that does not support LP-WUS, preventing the UE from using the WUR to receive LP-WUS, which is detrimental to the UE's energy saving. Summary of the Invention

[0006] This application provides a communication method and apparatus for reducing the power consumption of a terminal.

[0007] Optionally, in the various aspects of this application described below, the first frequency is the frequency of a neighboring cell, such as a neighboring cell of the serving cell of the terminal. For example, the first frequency includes one or more of the following: co-frequency, inter-frequency, or inter-system frequencies.

[0008] Optionally, in the various aspects of this application described below, the first frequency supporting LP-WUS may include: the first frequency being configured with LP-WUS or LP-WUS functionality, or the first frequency being enabled with LP-WUS or LP-WUS functionality, or the first frequency using LP-WUS or LP-WUS functionality, etc.

[0009] In a first aspect, a first communication method is provided, which can be applied to a terminal-side device, also referred to as a terminal device. The terminal device is, for example, a terminal equipment, or other equipment including terminal equipment functions, or a circuit, or a system-on-a-chip (or, a chip, such as a modem chip, also known as a baseband chip, or a system-on-a-chip (SoC) chip containing a modem core, or a system-in-package (SIP) chip) or other functional module, which is capable of implementing the functions of the terminal equipment, and which is, for example, disposed in the terminal equipment. The method includes: receiving first information, the first information indicating a first priority of a first frequency; setting the priority of the first frequency to a second priority, the second priority being higher than or equal to the first priority, the first frequency supporting LP-WUS, wherein the second priority is used to perform measurement and / or cell reselection.

[0010] Optionally, there exists a scenario where the first priority is used to perform measurements, and the second priority is used to perform cell reselection.

[0011] In this embodiment, the terminal can set the frequency priority according to whether LP-WUS is supported. For example, if the first frequency supports LP-WUS, the terminal can set the priority of the first frequency to a higher second priority. This gives the terminal a greater probability of selecting a cell under the first frequency when performing cell reselection. In this cell, the terminal can receive LP-WUS, thereby achieving energy saving.

[0012] In one alternative implementation, the second priority is the highest priority. The terminal can set the priority of the frequency that supports LP-WUS to the highest priority, thereby increasing the probability of the terminal reselecting a cell under that frequency.

[0013] In one optional implementation, the first frequency does not include the frequency corresponding to the serving cell of the terminal; or, the first frequency includes the frequency corresponding to the serving cell of the terminal. For example, the terminal may not adjust the frequency corresponding to the serving cell, so that the terminal can reselect to a cell at another frequency as much as possible. Alternatively, the terminal may adjust the frequency of the serving cell, so that the terminal may either reselect to another frequency or continue to camp on the serving cell.

[0014] In one optional implementation, the first frequency supporting LP-WUS includes: all cells under the first frequency supporting LP-WUS; or, at least one cell under the first frequency supporting LP-WUS. In this embodiment, LP-WUS support can be frequency-level, meaning whether or not LP-WUS is supported refers to whether a specific frequency supports LP-WUS, without discussing whether cells under that frequency support LP-WUS. Alternatively, LP-WUS support can also be cell-level, meaning whether or not LP-WUS is supported refers to whether a specific cell supports LP-WUS, without discussing whether the frequency to which that cell belongs supports LP-WUS. Alternatively, whether or not LP-WUS is supported can be at other granularities, without limitation.

[0015] In an optional implementation, the method further includes: when at least one cell in the first frequency supports LP-WUS, during cell reselection, prioritizing reselection to the at least one cell. For example, LP-WUS support is at the cell level; if at least one cell in the first frequency supports LP-WUS, while the remaining cells do not, the terminal can prioritize reselecting to the at least one cell, or during cell reselection, it can prioritize determining whether reselection to the at least one cell is possible, so that the terminal reselects to a cell that supports LP-WUS as much as possible.

[0016] In an optional implementation, the method further includes: receiving second information, the second information indicating M frequencies, wherein M1 of the M frequencies support LP-WUS, M2 of the M frequencies do not support LP-WUS, M1 + M2 = M, and the first frequency belongs to the M1 frequencies. For example, the M frequencies may include some or all of the frequencies to be measured by the terminal. The second information can indicate which of the M frequencies support LP-WUS, thereby allowing the terminal to determine the frequencies among the M frequencies that support LP-WUS.

[0017] In an optional implementation, the second information is further used to indicate the type of LP-WUS supported by the first frequency. LP-WUS can have multiple types, and a specific frequency supporting LP-WUS can support one or more LP-WUS types. The second information can indicate the specific LP-WUS type supported by a particular frequency.

[0018] In one optional implementation, the first frequency supports LP-WUS, including: the first frequency supports a first type of LP-WUS, wherein the first type of LP-WUS is supported by the terminal. This can be understood as follows: if the LP-WUS type supported by the first frequency is the same as or overlaps with the LP-WUS type supported by the terminal, the terminal considers the first frequency to support LP-WUS; conversely, if the LP-WUS type supported by the first frequency is different from or does not overlap with the LP-WUS type supported by the terminal, the terminal considers the first frequency not to support LP-WUS.

[0019] In one optional implementation, the first frequency supporting the first type of LP-WUS includes: all cells under the first frequency supporting the first type of LP-WUS; or, at least one cell under the first frequency supporting the first type of LP-WUS. For example, LP-WUS support can be at the cell level, and therefore LP-WUS type support can also be at the cell level. For example, the first frequency supporting the first type of LP-WUS could include all cells under the first frequency supporting the first type of LP-WUS, or it could include at least one cell under the first frequency supporting the first type of LP-WUS.

[0020] In an optional implementation, the method further includes: when at least one cell in the first frequency supports the first type of LP-WUS, during cell reselection, the terminal preferentially reselects to the at least one cell. For example, LP-WUS type support is at the cell level. If at least one cell in the first frequency supports the first type of LP-WUS, while the remaining cells do not support the first type of LP-WUS (e.g., the remaining cells do not support LP-WUS, or although they support LP-WUS, they do not support the first type of LP-WUS), then the terminal can preferentially reselect to the at least one cell, or during cell reselection, it can preferentially determine whether it is possible to reselect to the at least one cell, so that the terminal reselects to a cell that supports the first type of LP-WUS as much as possible.

[0021] In an optional implementation, the method further includes: setting the priority of a second frequency among the M frequencies to a third priority, wherein the third priority is lower than or equal to a fourth priority of the second frequency, the second frequency being a frequency that the terminal determines does not support LP-WUS, and the second frequency belongs to the M1 frequencies and / or the M2 frequencies, wherein the third priority is used to perform measurement and / or cell reselection, and the first information is also used to indicate the fourth priority. For example, if the terminal believes that the second frequency does not support LP-WUS, the terminal can set the priority of the second frequency to a lower third priority, so that when performing cell reselection, the terminal will try not to reselect to the second frequency, but has a greater probability of being able to select a cell under a frequency that supports LP-WUS, in which the terminal can receive LP-WUS, thereby achieving energy saving.

[0022] In one optional implementation, the third priority is the lowest priority. The terminal can set the priority of frequencies that do not support LP-WUS to the lowest priority, thereby reducing the probability of the terminal reselecting a cell under that frequency and correspondingly increasing the probability of the terminal reselecting a cell under a frequency that supports LP-WUS.

[0023] In one optional implementation, the fourth priority is higher than the priority of the frequency corresponding to the serving cell of the terminal. For example, for frequencies that do not support LP-WUS among high-priority frequencies, the terminal can lower their priority; while for frequencies that do not support LP-WUS among frequencies of equal or lower priority, the terminal can leave their priority unchanged. If the terminal cannot select a suitable target cell among frequencies that support LP-WUS, the terminal can continue to select cells among frequencies that do not support LP-WUS. Since the terminal does not adjust the priority of some frequencies that do not support LP-WUS, it is advantageous for the terminal to select cells among frequencies that do not support LP-WUS.

[0024] In one optional implementation, the second frequency does not include the frequency corresponding to the serving cell of the terminal; or, the second frequency includes the frequency corresponding to the serving cell of the terminal. For example, the terminal may not adjust the frequency corresponding to the serving cell, so that the terminal can reselect to a cell at another frequency as much as possible. Alternatively, the terminal may adjust the frequency of the serving cell, so that the terminal may either reselect to another frequency or continue to camp on the serving cell.

[0025] In one optional implementation, the second frequency is a frequency that the terminal determines does not support LP-WUS, including: the type of LP-WUS supported by the second frequency is different from the type of LP-WUS supported by the terminal; or, the second frequency does not support LP-WUS. This can be understood as follows: if the type of LP-WUS supported by the second frequency is the same as or overlaps with the type of LP-WUS supported by the terminal, the terminal considers the second frequency to support LP-WUS; or, if the type of LP-WUS supported by the second frequency is different from or does not overlap with the type of LP-WUS supported by the terminal, the terminal considers the second frequency not to support LP-WUS; or, if the capability of the second frequency does not support LP-WUS, the terminal considers the second frequency not to support LP-WUS.

[0026] In an optional implementation, the method further includes: receiving a first LP-WUS, the first LP-WUS being used to wake up the terminal; setting the priority of the first frequency to the first priority and / or setting the priority of the second frequency to the fourth priority. For example, if the terminal reselects to a cell (e.g., the first cell) through the aforementioned method, the terminal can detect the LP-WUS in the first cell. For example, if the terminal receives the first LP-WUS and determines that it has been woken up based on the first LP-WUS, in this case, the terminal can restore the priority of the first frequency and / or the second frequency. For example, the terminal can perform cell measurement and / or cell reselection based on the restored priority to reselect to the corresponding cell, thereby entering the RRC connected state in that cell. For example, a large number of terminals may have reselected to the first cell. If all these terminals need to enter the RRC connected state in the first cell, it may cause the first cell to be overloaded. Therefore, in this embodiment, if a terminal needs to enter the RRC connected state (e.g., woken up by the first LP-WUS, or determined to be paged based on a received paging message), the terminal can perform cell reselection again to enter the RRC connected state in another cell, reducing the load on the first cell.

[0027] In one optional implementation, the method is applied to terminals that support LP-WUS, terminals with WUR capability, terminals with LP-WUS detection configured, or terminals with LP-WUS detection enabled. For example, for terminals that do not support LP-WUS, terminals without WUR capability, terminals where LP-WUS detection is not configured, or terminals where LP-WUS detection is not enabled, the technical solutions of the embodiments of this application may not be used. For example, conventional technical solutions (e.g., without changing the frequency priority) may be used to perform cell measurement and / or cell reselection.

[0028] Secondly, a second communication method is provided, which can be applied to a terminal-side device, also referred to as a terminal device. A description of the implementation of this terminal device can be found in the first aspect. The method includes: receiving first information, the first information indicating a fourth priority of a second frequency; setting the priority of the second frequency to a third priority, the third priority being lower than or equal to the fourth priority, wherein the second frequency is a frequency determined by the terminal to not support LP-WUS, and the third priority is used to perform measurements and / or cell reselection.

[0029] In one alternative implementation, the third priority is the lowest priority.

[0030] In one alternative implementation, the fourth priority is higher than the priority of the frequency corresponding to the serving cell of the terminal.

[0034] In an optional implementation, the method further includes: setting the priority of a first frequency among the M1 frequencies to a second priority, the second priority being higher than or equal to the first priority, wherein the second priority is used to perform measurements and / or cell reselection, and the first information is also used to indicate the first priority.

The method includes: determining a first frequency and a second frequency, the first frequency supporting LP-WUS and the second frequency not supporting LP-WUS; performing a first process on the first frequency, wherein the first process includes measurement and / or cell reselection.

[0046] In this embodiment, the terminal can prioritize frequencies that support LP-WUS, thus increasing the probability of selecting a cell with a frequency supporting LP-WUS during cell reselection. Within this cell, the terminal can receive LP-WUS signals, achieving energy savings. Furthermore, the terminal does not need to reset frequency priorities, simplifying terminal implementation.

[0047] In one optional implementation, after performing the first processing on the first frequency, the method further includes performing a second processing on the second frequency, the second processing including measurement and / or cell reselection. The terminal may prioritize processing frequencies that support LP-WUS before processing frequencies that do not support LP-WUS, thereby increasing the probability that the terminal can select a cell on a frequency that supports LP-WUS when performing cell reselection.

[0052] For information on the technical effects of the third aspect or various alternative implementation methods, please refer to the description of the technical effects of the first aspect or corresponding implementation methods.

[0053] Fourthly, a fourth communication method is provided, which can be applied to a network-side device, also referred to as a network device. This network device is, for example, a network equipment, or other equipment including network equipment functions, or a circuit, or a system-on-a-chip (or chip), or other functional module capable of implementing the functions of the network equipment, and is, for example, disposed within the network equipment. The network equipment includes, for example, core network equipment and / or access network equipment. The method includes: transmitting second information, the second information indicating M frequencies, wherein M1 of the M frequencies support LP-WUS, M2 of the M frequencies do not support LP-WUS, and M1 + M2 = M.

[0054] In an alternative implementation, the second information is further used to indicate the type of LP-WUS supported by each of the M1 frequencies.

[0056] Regarding the technical effects of the fourth aspect or various optional implementation methods, reference may be made to one or more of the following: a description of the technical effects of the first aspect or corresponding implementation method, a description of the technical effects of the second aspect or corresponding implementation method, or a description of the technical effects of the third aspect or corresponding implementation method.

[0057] Fifthly, a fifth communication method is provided, which can be applied to a terminal-side device, also referred to as a terminal device. A description of the implementation of this terminal device can be found in the first aspect. The method includes: receiving second information, the second information indicating the type of LP-WUS supported by the first frequency.

[0058] Optionally, the terminal can set the priority of the first frequency based on the second information. For example, the priority of the first frequency can be set to a higher priority, so that the terminal has a greater probability of reselecting a cell under the first frequency, thereby achieving the effect of energy saving.

[0059] In an optional implementation, the method further includes: setting the priority of the first frequency to a second priority, the first frequency supporting a first type of LP-WUS, wherein the first type of LP-WUS is supported by the terminal, and the second priority is used to perform measurements and / or cell reselection.

[0060] In an optional implementation, the method further includes: receiving first information, the first information indicating a first priority of the first frequency, and a second priority being higher than or equal to the first priority. The terminal can set the second priority by referring to the first priority, or it can choose not to refer to the first priority, offering greater flexibility.

[0061] In one alternative implementation, the second priority is the highest priority. Setting the priority of the first frequency to the highest priority increases the probability that the terminal can reselect a cell under the first frequency.

[0062] Sixthly, a sixth communication method is provided, which can be applied to a network-side device, also referred to as a network device for example. Implementation details of this network device can be found in the description of the fourth aspect.

[0063] In an alternative implementation, the method further includes: sending first information, the first information indicating a first priority of the first frequency, the first frequency supporting a first type of LP-WUS.

[0064] A seventh aspect provides a seventh communication method applicable to a terminal-side device, also referred to as a terminal device.

[0065] In this embodiment, for terminals with WUR capability, a first priority associated with LP-WUS can be used to perform measurement and / or cell reselection, increasing the probability that the terminal can select a cell with a frequency supporting LP-WUS. Within this cell, the terminal can receive LP-WUS signals, thus achieving energy savings. For terminals without WUR capability, a second priority can be used to perform measurement and / or cell reselection.

[0067] In one alternative implementation, after determining the first priority, the method further includes performing measurement and / or cell reselection using the first priority. Alternatively, the terminal may omit the "determining the first priority" step and instead, after receiving the first information, perform measurement and / or cell reselection using the first priority. For example, for a terminal supporting LP-WUS, the first priority can be used to perform measurement and / or cell reselection to reselect to a cell supporting LP-WUS as much as possible.

[0068] In an optional implementation, the method further includes performing measurement and / or cell reselection using the second priority. Alternatively, the terminal may omit the "determine second priority" step and instead perform measurement and / or cell reselection using the second priority after receiving the first information. For example, for terminals that do not support LP-WUS, measurement and / or cell reselection can be performed using the second priority.

[0069] In one optional implementation, performing measurement and / or cell reselection using the first priority includes: performing measurement and / or cell reselection using a first cell reselection priority, wherein the first priority indicates the first cell reselection priority; or, performing measurement and / or cell reselection using a first cell reselection priority and a first cell reselection sub-priority, wherein the first priority indicates the first cell reselection priority and the first cell reselection sub-priority; or, performing measurement and / or cell reselection using a first cell reselection sub-priority, a second cell reselection priority, and a second cell reselection sub-priority, wherein the first priority indicates the first cell reselection sub-priority, and the second priority indicates the second cell reselection priority and the second cell reselection priority. The terminal may determine the priority for measurement and / or cell reselection in multiple ways, without limitation.

[0070] In one alternative implementation, the first priority corresponds to or is associated with LP-WUS. For example, the first priority may be determined based on LP-WUS, so that when a terminal performs measurements and / or cell reselection based on the first priority, it is more likely to reselect to a cell that supports LP-WUS.

[0071] In one alternative implementation, the second priority is independent of or does not correspond to LP-WUS.

[0072] Eighthly, an eighth communication method is provided, which can be applied to a network-side device, also referred to as a network device. Implementation details of this network device can be found in the fourth aspect. The method includes: transmitting first information, the first information indicating a first priority and a second priority of a first frequency, the first priority being used to perform measurement and / or cell reselection, and the second priority being used to perform measurement and / or cell reselection.

[0073] In one alternative implementation, the first priority corresponds to LP-WUS.

[0074] In one alternative implementation, the first priority is determined based on second information, which includes information on whether the first frequency supports LP-WUS.

[0075] In one optional implementation, the second information includes information about the first frequency supporting LP-WUS, and the second information also includes information about the type of LP-WUS supported by the first frequency.

[0076] In one alternative implementation, the first priority is higher than the priority of frequencies that do not support LP-WUS.

[0077] In one alternative implementation, the second priority is independent of LP-WUS.

[0078] For the technical effects of the eighth aspect or various alternative implementations, please refer to the description of the technical effects of the seventh aspect or corresponding implementations.

[0079] Ninthly, a communication device is provided. The communication device can be a terminal-side device as described in any of the first to eighth aspects above.

For example, the communication device has the functions described in any of the first to eighth aspects above; for example, the communication device includes modules, units, or means corresponding to the operations described in any of the first to eighth aspects above.

In one optional implementation, the communication device includes a baseband device and a radio frequency device. In another optional implementation, the communication device includes a processing unit (sometimes also called a processing module) and a transceiver unit (sometimes also called a transceiver module). A transceiver unit can perform both sending and receiving functions. When the transceiver unit performs the sending function, it can be called a sending unit (sometimes also called a sending module), and when it performs the receiving function, it can be called a receiving unit (sometimes also called a receiving module). The sending unit and the receiving unit can be the same functional module, which is called the transceiver unit and can perform both sending and receiving functions; or, the sending unit and the receiving unit can be different functional modules, and the transceiver unit is a collective term for these functional modules.

[0080] In one optional implementation, the transceiver unit (or the receiving unit) is configured to receive first information, the first information being used to indicate a first priority of a first frequency; the processing unit is configured to set the priority of the first frequency to a second priority, the second priority being higher than or equal to the first priority, the first frequency supporting LP-WUS, wherein the second priority is used to perform measurements and / or cell reselection.

[0082] In one optional implementation, the processing unit is configured to determine a first frequency and a second frequency, the first frequency supporting LP-WUS and the second frequency not supporting LP-WUS; the processing unit is further configured to perform a first process on the first frequency, wherein the first process includes measurement and / or cell reselection.

[0109] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0110] In this application embodiment, the number of nouns, unless otherwise specified, refers to "singular nouns or plural nouns," that is, "one or more." "At least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. For example, A / B means: A or B. "At least one of the following" or similar expressions refer 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, and c can be single or multiple.

[0111] The ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects, and are not used to limit the size, content, order, timing, priority, or importance of the multiple objects. Furthermore, the numbering of steps in the various embodiments described in this application is only to distinguish different steps and is not used to limit the order in which the steps are performed.

[0112] The following explanations of some terms or concepts used in the embodiments of this application are provided to facilitate understanding by those skilled in the art.

[0113] In this embodiment, the terminal device is a device with wireless transceiver capabilities, which can be a fixed device, a mobile device, a handheld device (e.g., a mobile phone), a wearable device, an in-vehicle device, or a wireless device (e.g., a communication module, a modem, or a chip system, etc.) built into the aforementioned devices. The terminal device is used to connect people, objects, machines, etc., and can be widely used in various scenarios, including but not limited to the following: sensing scenarios, cellular communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-to-machine / machine-type communications (M2M / MTC) communication, Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, self-driving, remote medical care, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart city, drones, robots, and indoor commercial scenarios (such as mobile phone screen mirroring, file sharing, and mobile phone to VR glasses video transmission). When the terminal equipment is applied to V2X, it can also be called a V2X device, such as a smart car, digital car, unmanned car, driverless car, pilotless car, or automobile, self-driving car, or autonomous car, pure electric vehicle (EV), hybrid electric vehicle (HEV), range-extended electric vehicle (REEV), plug-in hybrid electric vehicle (PHEV), new energy vehicle, or roadside unit (RSU). The terminal equipment can also be a device used in D2D communication, such as an electricity meter or water meter.

[0114] Furthermore, in this embodiment of the application, the terminal device can also be a terminal device in an Internet of Things (IoT) system. IoT is an important component of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection.

[0115] The various terminal devices described above, if located in a vehicle (e.g., placed inside or installed inside a vehicle), can all be considered in-vehicle terminal devices, also known as on-board units (OBUs). The terminal device of this application can also be an in-vehicle module, in-vehicle component, in-vehicle chip, or in-vehicle unit built into a vehicle as one or more components or units. The vehicle can implement the methods of this application through the built-in in-vehicle module, in-vehicle component, in-vehicle chip, or in-vehicle unit.

[0116] The terminal equipment may sometimes be referred to as UE, terminal, access station, UE station, remote station, wireless communication equipment, or user equipment, etc.

[0117] In this application embodiment, the communication device used to implement the terminal device function can be a terminal device, which can be a terminal device or a device capable of supporting the terminal device to implement the function, such as a chip system. This device can be installed in the terminal device. In the technical solutions provided in this application embodiment, the example of a terminal device being used to implement the terminal device function is used to describe the technical solutions provided in this application embodiment.

[0118] The network devices in this application embodiment include, for example, access network devices (or access network elements) and / or core network devices (or core network elements). The access network devices are devices with wireless transceiver capabilities, used to communicate with the terminal devices. The access network devices include, but are not limited to, base stations (base transceiver stations, BTS, Node B, evolved Node B (eNodeB) / eNB, or the next generation Node B (gNodeB) / gNB), transmission reception points (TRPs), base stations evolved from the 3rd generation partnership project (3GPP), access nodes in wireless fidelity (Wi-Fi) systems, wireless relay nodes, wireless backhaul nodes, etc. The base stations can be: macro base stations, micro base stations, pico base stations, small cells, relay stations, etc. Multiple base stations can support networks using the same access technology or networks using different access technologies. A base station can contain one or more co-located or non-co-located transmission and reception points. The access network equipment can also be a radio controller, centralized unit (CU), and / or distributed unit (DU) in a cloud radio access network (CRAN) scenario. The access network equipment can also be a server, etc. For example, the network equipment in V2X technology can be a roadside unit (RSU). The following description uses a base station as an example to illustrate the access network equipment. A base station can communicate with a terminal device, or it can communicate with a terminal device through a relay station. A terminal device can communicate with multiple base stations in different access technologies. The core network equipment is used to implement functions such as mobility management, data processing, session management, policy and billing. The names of the equipment implementing core network functions may differ in systems using different access technologies; this application does not limit this.Taking the 5th generation (5G) mobile communication technology system as an example, the core network equipment includes, for example, access and mobility management function (AMF), session management function (SMF), policy control function (PCF), or user plane function (UPF), etc.

[0119] In a CU-DU architecture, or in an open RAN (ORAN) system, access network equipment may include one or more logical network elements such as a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). CUs and DUs may be separate entities or included in the same network element, such as a baseband unit (BBU). RUs may be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0120] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open CU (O-CU), DU can also be called an open DU (O-DU), CU-CP can also be called an open CU-CP (O-CU-CP), CU-UP can also be called an open CU-UP (O-CU-CP), and RU can also be called an open RU (O-RU). For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples in its embodiments. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in the embodiments of this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0121] The CU and DU can be configured according to the protocol layer functions of the wireless network they implement. For example, the CU can be configured to implement the functions of the Packet Data Convergence Protocol (PDCP) layer and above (such as the Radio Resource Control (RRC) layer and / or the Service Data Adaptation Protocol (SDAP) layer); the DU can be configured to implement the functions of protocol layers below the PDCP layer (such as one or more of the Radio Link Control (RLC) layer, Media Access Control (MAC) layer, or Physical (PHY) layer). As another example, the CU can be configured to implement the functions of protocol layers above the PDCP layer (such as the RRC and / or SDAP layers), and the DU can be configured to implement the functions of protocol layers below the PDCP layer (such as one or more of the RLC, MAC, or PHY layers).

[0122] The above CU and DU configurations are merely examples; the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements, such as by latency. Functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0123] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0124] In this application embodiment, the communication device used to implement the functions of a network device can be called a network device. This network device can be a network element, a network device, or a device capable of supporting the network device or network element to implement the function, such as a chip system. This device can be installed in the network device. In the technical solutions provided in this application embodiment, the device used to implement the functions of a network device is described as a network device (for example, the device used to implement the functions of an access network device is an access network device, and the device used to implement the functions of a core network device is a core network device).

[0125] The technical features involved in the embodiments of this application are described below.

[0126] When a UE is in RRC idle or RRC inactive state, it calculates the location of the paging frame (PF) and the location of the paging occasion (PO) within a PF based on its UE ID, and receives the paging within the PO. Whether the UE is in RRC idle or RRC inactive state performing the above paging reception procedure, or in RRC connected state receiving data, it uses the same receiving module, which is referred to as the main radio (MR). A UE operating in MR can be operating on a 5G NR main link.

[0127] To further reduce power consumption, the UE can also use a circuit independent of the MR to receive signals, for example, referred to as circuit A. Circuit A can be implemented using a simple circuit or chip with low power consumption. Circuit A is used to receive the wake-up signal (WUS) from the network device; the WUS received through circuit A is also called LP-WUS. When the UE detects or receives LP-WUS and demodulates the wake-up indication information based on the information carried in LP-WUS, the UE wakes up the MR that is turned off (or in a sleep state). LP-WUS can be used to wake up at least one UE or at least a group of UEs. Circuit A is, for example, called wake-up radio (WUR). To reduce the power consumption of the WUR circuit, the LP-WUS signal typically uses simple modulation methods such as on-off keying (OOK); correspondingly, the WUR in the UE uses envelope detection to receive the LP-WUS. The UE using circuit A to receive the wake-up signal can be described as operating on the WUR / LR link, or as the WUR / LR being in a working state.

[0128] For example, upon power-on, the UE can first search for the NR primary link signal in the MR. If the NR primary link signal is found, it can camp on the NR primary link. If the NR primary link signal indicates LP-WUS configuration information, the UE can further search for LP-WUS in circuit A based on the LP-WUS configuration information. If LP-WUS is found and its signal quality is good, the UE can operate in circuit A. Alternatively, upon power-on, the UE can first search for the NR primary link signal in the MR. If the NR primary link signal cannot be found, it can search for LP-WUS based on the pre-set configuration information within the UE. If LP-WUS is found and its signal quality is good, the UE can operate in circuit A.

[0129] Referring to Figure 1, which illustrates the operation of circuit A and MR, circuit A is shown as a low-power circuit in Figure 1. After the low-power circuit is in operation, if the UE detects LP-WUS, it can trigger the MR to receive paging or initiate random access, etc.; however, if the UE does not detect LP-WUS, it does not need to trigger the MR to be activated, and the MR can remain off (or remain in sleep mode), thereby reducing the MR's operating time and saving the UE's power consumption.

[0130] In 5G NR, the UE can perform radio resource management (RRM) measurements of the serving cell and neighbor cells in RRC idle or RRC inactive states. RRM measurements are used for cell reselection. Neighbor cell measurements further include one or more of intra-frequency, inter-frequency, or inter-system (RAT) measurements. Current standards define measurement requirements; for example, the UE needs to perform a measurement at least once every time interval T. During measurement, the UE should measure the serving cell and simultaneously measure neighbor cells according to the S criterion configured by the base station. The UE performs neighbor cell measurements according to the S criterion as follows: for test frequencies with a priority higher than the serving cell frequency, the UE should measure them; for test frequencies with a priority equal to or lower than the current serving cell frequency, if the current measurement result of the serving cell is higher than the threshold corresponding to the S criterion, the UE does not need to measure these test frequencies; if the current measurement result of the serving cell is lower than or equal to the threshold corresponding to the S criterion, the UE needs to measure these test frequencies.

[0131] Based on measurement results, the UE can decide whether to remain in the current serving cell (e.g., the cell where the UE is currently camped) or perform cell reselection to ensure that the UE camps in a cell with better channel quality. For example, for cells on frequencies with higher reselection priority (also known as high-priority frequencies), if the signal quality value of a neighboring cell exceeds a certain threshold within a certain time interval, the UE should perform cell reselection. Therefore, for cells on frequencies with higher reselection priority, even if the signal quality of the serving cell is better, the UE may still reselect to a cell on a frequency with higher reselection priority. For cells on frequencies with the same reselection priority as the serving cell (also known as equal-priority frequencies), the UE can perform cell reselection according to the R criterion. The R criterion means that based on the signal quality of the cell, a rank (R) value is calculated for each neighboring cell and the serving cell. Cells are ranked according to their R values. Neighboring cells with an R value greater than that of the current serving cell meet the reselection criteria. If multiple neighboring cells meet the reselection criteria, the cell with the best signal quality is selected. For cells on frequencies with lower reselection priority (also known as low-priority frequencies), the reselection conditions are more stringent. For example, the reselection condition is that if the signal quality value of the serving cell is lower than a certain threshold and the signal quality value of the neighboring cell is higher than a certain threshold within a certain time interval, then the UE should perform cell reselection.

[0132] During cell reselection, the UE is likely to reselect to a cell that does not support LP-WUS, which will prevent the UE from receiving LP-WUS using WUR, thus hindering the UE's energy saving.

[0133] Therefore, the UE in this application embodiment can set the frequency priority according to whether it supports LP-WUS. For example, if the first frequency supports LP-WUS, the UE can set the priority of the first frequency to a higher second priority. Thus, when the UE performs cell reselection, it has a greater probability of being able to select a cell under the first frequency. In this cell, the UE can receive LP-WUS, thereby achieving energy saving.

[0134] The technical solutions provided in this application can be applied to 4G systems, such as Long Term Evolution (LTE) systems, or to 5G systems, such as New Radio (NR) systems, or to next-generation mobile communication systems or other similar communication systems, such as future communication systems, without specific limitations. Furthermore, the technical solutions provided in this application can also be applied to D2D scenarios, such as NR-D2D scenarios, or to V2X scenarios, such as NR-V2X scenarios. For example, the embodiments of this application can be used in fields such as factory manufacturing, smart homes, intelligent driving, assisted driving, intelligent connected vehicles, or indoor commercial scenarios. The methods provided in this application can also be applied to satellite communication systems, such as non-terrestrial networks (NTNs), wherein the satellite communication system can be integrated with the aforementioned communication systems.

[0135] Please refer to Figure 2, which is a schematic diagram of an application scenario according to an embodiment of this application. Figure 2 includes a UE and a network device, which may include access network equipment and / or core network equipment. For example, the UE camps on a cell provided by the network device.

[0136] The method provided in the embodiments of this application is described below with reference to the accompanying drawings. In various embodiments of this application, the main radio (MR) may also be called the main receiver (MR), or may have other names. MR will be used as an example in the following description, and it can be understood that MR in the following description can refer to the main radio or the main receiver. In various embodiments of this application, the wake-up radio (WUR) may also be called the wake-up receiver (WUR), wake-up circuit, low-power radio (LR), or wake-up receiver module, or may have other names. WUR will be used as an example in the following description, and it can be understood that WUR in the following description can refer to the wake-up radio or the wake-up receiver, and WUR in the following description can also be replaced by the wake-up circuit, low-power circuit, or wake-up receiver module, etc. In various embodiments of this application, neighbor cell measurement may include one or more of the following: same-frequency measurement, different-frequency measurement, or different-system measurement; or it can be understood that the neighbor cells described in various embodiments of this application may include one or more of the following: same-frequency neighbor cells, different-frequency neighbor cells, or different-system neighbor cells. Among them, "same-frequency neighboring cell" refers to a neighboring cell whose frequency is the same as that of the UE's serving cell; "different-frequency neighboring cell" refers to a neighboring cell whose frequency is different from that of the UE's serving cell; and "different-system neighboring cell" refers to a neighboring cell whose radio access technology (RAT) is different from that of the UE's serving cell. The UE's serving cell is, for example, the cell where the UE is camped.

[0137] In various embodiments of this application, the priority of a frequency (e.g., the first priority, second priority, etc., described below) can refer to the cell reselection priority or the absolute priority of that frequency. The absolute priority can be determined based on the cell reselection priority of the frequency, or based on the cell reselection priority and the cell reselection sub-priority of the frequency. For example, a network device can configure a cell reselection priority for a frequency using the cellReselectionPriority parameter, and it can also configure a cell reselection sub-priority for a frequency using the cellReselectionSubPriority parameter. If a network device configures a cell reselection priority for a frequency but not a cell reselection sub-priority, then the cell reselection priority for that frequency is its absolute priority. Alternatively, if a network device configures both a cell reselection priority and a cell reselection sub-priority for a frequency, then the absolute priority of that frequency can be determined based on these two factors; for example, adding the cell reselection priority to the cell reselection sub-priority gives the absolute priority of the frequency. The cell reselection priority parameter (cellReselectionPriority) can range from 0 to 7, with a higher value indicating a higher cell reselection priority. The cell reselection sub-priority parameter (CellReselectionSubPriority) can range from 0.2, 0.4, 0.6, to 0.8. This means that cells on the same frequency using the same access technology have the same absolute priority, while cells on different frequencies may have the same or different absolute priorities.

[0138] The various embodiments described herein can be applied to the network architecture shown in Figure 2. For example, the UE described in the various embodiments of this document can be the UE in Figure 2, and the network device described in the various embodiments of this document can be the network device in Figure 2.

[0139] This application provides a first communication method, please refer to Figure 3, which is a flowchart of the method.

[0140] S301, The network device sends the first information. Correspondingly, the UE receives the first information.

[0141] The first information may indicate the priority of a first frequency, such as first priority. For example, the first information indicates a first frequency, such as by including information about the first frequency, which may include information about the first priority, indicating that the first frequency has the first priority. The first frequency may include N frequencies, where N is a positive integer. For example, these N frequencies may be all or some of the frequencies to be measured by the UE. Alternatively, the first frequency may be a frequency from a neighboring cell, and may include one or more of the following: same-frequency frequencies, different-frequency frequencies, or frequencies from different systems. By measuring the frequencies to be measured, the UE can perform cell reselection based on the measurement results.

[0142] The first priority can be the original priority of the first frequency, which is the priority configured by the network device for the UE to perform measurements and / or cell reselection. For example, the first priority can be higher than, equal to, or lower than the priority of the frequency corresponding to the UE's serving cell.

[0143] S302, The UE sets the priority of the first frequency to the second priority.

[0144] The second priority can be used to perform measurements and / or cell reselection. For example, the second priority can be used to perform measurements and / or cell reselection; or, the first priority can be used to perform measurements and the second priority can be used to perform cell reselection. Here, measurement can be understood as performing RRM measurements on the frequencies of the neighboring cells to be measured, and this measurement can be used for cell reselection, for example, the measurement results obtained through this measurement can be used for cell reselection.

[0145] The first frequency may support LP-WUS or support LP-WUS functionality. Here, "a frequency supports LP-WUS or supports LP-WUS functionality" can mean that the frequency itself supports LP-WUS or LP-WUS functionality, or it can be understood as the frequency's capability (or configuration) supporting LP-WUS or LP-WUS functionality. LP-WUS functionality can also be referred to as an LP-WUS feature. In this embodiment, "the first frequency supports LP-WUS or supports LP-WUS functionality" can be understood as the first frequency always supporting LP-WUS or LP-WUS functionality. For example, after configuring LP-WUS or LP-WUS functionality for the first frequency, the first frequency supports LP-WUS or LP-WUS functionality, and the configuration is considered effective.

[0146] Alternatively, the first frequency supports LP-WUS or LP-WUS functionality, or it can be described as the first frequency being configured with LP-WUS, for example, configuration means it is active.

[0147] Alternatively, supporting LP-WUS or LP-WUS functionality on the first frequency can also be described as the first frequency having LP-WUS or LP-WUS functionality enabled. This can be understood as follows: the first frequency can be configured with LP-WUS (or LP-WUS functionality). If configured but not enabled, LP-WUS (or LP-WUS functionality) on the first frequency will not be effective, and the first frequency will still not support LP-WUS or LP-WUS functionality; if configured and then enabled, LP-WUS (or LP-WUS functionality) on the first frequency will be effective, and the first frequency will support LP-WUS or LP-WUS functionality. Alternatively, configuration can be interpreted as enabling; therefore, if the first frequency is configured with LP-WUS or LP-WUS functionality, it means that LP-WUS or LP-WUS functionality is enabled.

[0148] Alternatively, supporting LP-WUS or LP-WUS functionality on the first frequency can also be described as the first frequency having LP-WUS or LP-WUS functionality enabled. This can be understood as follows: the first frequency can be configured with LP-WUS (or LP-WUS functionality). If configured but not enabled, LP-WUS (or LP-WUS functionality) on the first frequency will not be effective, and the first frequency will still not support LP-WUS or LP-WUS functionality. Enabling it after configuration will enable LP-WUS (or LP-WUS functionality) on the first frequency, and the first frequency will support LP-WUS or LP-WUS functionality. Alternatively, configuration can be interpreted as enabling; therefore, as long as the first frequency is configured with LP-WUS or LP-WUS functionality, it means that LP-WUS or LP-WUS functionality is enabled.

[0149] Alternatively, the first frequency supporting LP-WUS or LP-WUS functionality can also be described as the first frequency using (or being able to use, or being able to use) LP-WUS or LP-WUS functionality. For example, the first frequency may be configured with LP-WUS or LP-WUS functionality, but the first frequency is considered to support LP-WUS or LP-WUS functionality only if the first frequency is about to use, is capable of using, or has already started using LP-WUS or LP-WUS functionality.

[0150] Alternatively, the statement "the first frequency supports LP-WUS" or LP-WUS functionality can be described in other ways, such as "the first frequency supports WUR," etc., without limitation. The following description will use "the first frequency supports LP-WUS" as an example. Besides the first frequency, other frequencies may also support LP-WUS or LP-WUS functionality, and the understanding is similar.

[0151] Correspondingly, a frequency not supporting LP-WUS or LP-WUS functionality can mean that the frequency itself does not support LP-WUS or LP-WUS functionality, or it can be understood as the frequency's capability (or configuration) not supporting LP-WUS or LP-WUS functionality. For example, if a second frequency does not support LP-WUS or LP-WUS functionality, in this embodiment of the application, this can be understood as the second frequency never supporting LP-WUS or LP-WUS functionality. For example, if LP-WUS or LP-WUS functionality is not configured for the second frequency, then the second frequency does not support LP-WUS or LP-WUS functionality.

[0152] Alternatively, the second frequency may not support LP-WUS or LP-WUS functionality, or it may be described as the second frequency not being configured with LP-WUS.

[0153] Alternatively, the second frequency not supporting LP-WUS or LP-WUS functionality can also be described as the second frequency not having LP-WUS or LP-WUS functionality enabled. This can be understood as the second frequency being configured with LP-WUS (or LP-WUS functionality). If, after configuration, it is not enabled, then LP-WUS (or LP-WUS functionality) on the second frequency will not take effect, and the second frequency will still not support LP-WUS or LP-WUS functionality. Alternatively, configuration can be understood as enabling; therefore, if the second frequency is configured with LP-WUS or LP-WUS functionality, it means that LP-WUS or LP-WUS functionality is enabled. Therefore, the second frequency not having LP-WUS or LP-WUS functionality enabled specifically means that LP-WUS or LP-WUS functionality has not been configured.

[0154] Alternatively, the second frequency may not support LP-WUS or LP-WUS functionality, which can also be described as the second frequency not having LP-WUS or LP-WUS functionality enabled. This can be understood as the second frequency being configured with LP-WUS (or LP-WUS functionality). If configured but not enabled, then LP-WUS (or LP-WUS functionality) on the second frequency will not be effective, and the second frequency will still not support LP-WUS or LP-WUS functionality. Alternatively, configuration can be understood as enabling; therefore, if the second frequency is configured with LP-WUS or LP-WUS functionality, it means that LP-WUS or LP-WUS functionality is enabled. Therefore, the second frequency not having LP-WUS or LP-WUS functionality enabled specifically means that LP-WUS or LP-WUS functionality has not been configured.

[0155] Alternatively, the second frequency not supporting LP-WUS or LP-WUS functionality can also be described as the second frequency not using (or being unable to use, or being unable to use) LP-WUS or LP-WUS functionality. For example, the second frequency may be configured with LP-WUS or LP-WUS functionality, but if the first frequency does not use or is unable to use LP-WUS or LP-WUS functionality, it is assumed that the first frequency does not support LP-WUS or LP-WUS functionality.

[0156] Alternatively, the statement that the second frequency does not support LP-WUS or LP-WUS functionality can be described in other ways, such as stating that the second frequency does not support WUR, etc., without limitation. The following description will use "the second frequency does not support LP-WUS" as an example. Besides the second frequency, other frequencies may also not support LP-WUS or LP-WUS functionality, and the understanding is similar.

[0157] A frequency being configured with LP-WUS or LP-WUS functionality can mean either that the network device has configured LP-WUS or LP-WUS functionality for that frequency, or that the network device can support the use of LP-WUS or LP-WUS functionality on that frequency. If a frequency is configured with LP-WUS or LP-WUS functionality, for any UE using that frequency or a UE camped on that frequency, the frequency's capability is considered to support LP-WUS or LP-WUS functionality (although specific UEs supporting different LP-WUS types may perceive the frequency as supporting or not supporting LP-WUS functionality). A frequency not being configured with LP-WUS or LP-WUS functionality can mean either that the network device has not configured LP-WUS or LP-WUS functionality for that frequency, or that the network device cannot use LP-WUS or LP-WUS functionality on that frequency. If a frequency is not configured with LP-WUS or LP-WUS functionality, for any UE using that frequency, the frequency's capability is not considered to support LP-WUS or LP-WUS functionality.

[0158] The second priority can be higher than or equal to the first priority. This can be understood as the UE increasing the priority of frequencies supporting LP-WUS, so that during cell reselection, the UE is more likely to reselect cells on frequencies supporting LP-WUS, thus achieving energy savings. Optionally, the second priority can be the highest priority. For example, if there are eight frequency priorities, from priority 0 to priority 7, with priority 7 being the highest (e.g., priorities increase sequentially from 0 to 7, with priority 0 being the lowest and priority 7 the highest), then the second priority could be priority 7. Setting the priority of frequencies supporting LP-WUS to the highest priority increases the probability of the UE reselecting cells on those frequencies.

[0159] The first frequency includes N frequencies. For these N frequencies, the first priority of different frequencies can be the same or different, and the second priority of different frequencies can also be the same or different. For example, if the second priority of different frequencies among the N frequencies is the same, then the second priority can be the highest priority. Alternatively, if the second priorities of different frequencies among the N frequencies are different, then the second priority of a certain frequency among the N frequencies can be the highest priority, or it can be any priority that is higher than or equal to the first priority of that frequency.

[0160] Optionally, when setting a second priority for a first frequency, the UE may refer to the first priority. For example, if the UE determines the first priority based on the first information, it can set the priority of the first frequency to a priority that is higher than or equal to the first priority, and this priority is the second priority.

[0161] Alternatively, when setting a second priority for the first frequency, the UE may not refer to the first priority. For example, although the UE receives the first information, it may not determine the first priority based on this information; it can be assumed that the UE is unaware of the first priority. Or, the UE may not receive the first information, for example, if the UE fails to receive it, or if the network device does not send the first information, then the UE cannot know the first priority. In this case, the UE can directly set the priority of the first frequency to the highest priority (which is the second priority), a method that is relatively simple for the UE to implement.

[0162] Optionally, the first frequency may not include the frequency corresponding to the UE's serving cell. Here, the frequency corresponding to a cell can refer to the frequency of that cell, the frequency used by that cell, or the frequency in which that cell is located. For example, the frequency corresponding to the serving cell can refer to the frequency of that serving cell, the frequency used by that serving cell, or the frequency in which that serving cell is located. This can be understood as the first frequency not including the serving cell's frequency regardless of whether the serving cell supports LP-WUS. For example, the first frequency includes inter-frequency frequencies and / or inter-system frequencies, but excludes intra-frequency frequencies. This indicates that when the UE adjusts priorities, regardless of whether the serving cell supports LP-WUS, the UE can choose not to adjust the priority of the serving cell's frequency, making it more likely that the UE will reselect to another cell. For example, the second priority is used for cell reselection, or the UE can adjust the priority of LP-WUS-supporting frequencies when performing cell reselection (or the UE performs cell reselection according to the adjusted priority), but will not adjust the priority of LP-WUS-supporting frequencies when performing measurements (or the UE performs measurements according to the unadjusted priority). Then, the UE can determine the signal quality of the serving cell based on the measurement results. If the serving cell has poor signal quality, for example, if the signal quality is less than or equal to a first threshold, then the first frequency may not include the frequency of the UE's serving cell, regardless of whether the serving cell supports LP-WUS. That is, if the serving cell has poor signal quality, even if the serving cell supports LP-WUS, the UE may not prioritize the serving cell's frequency, thus making it more likely that the UE will reselect to another cell during cell reselection, allowing the UE to camp on a cell with better signal quality. The first threshold may be configured by the network device, determined by the UE itself, or predefined or pre-configured in the UE through a protocol.

[0163] Table 1 provides some examples of UE priority for adjusting frequencies supporting LP-WUS. Table 1 uses UE adjustment of different frequencies as an example.

[0164] Table 1

[0165] For example, in Table 1, inter-frequency 1, inter-frequency 3, and the serving cell's frequency all support LP-WUS. The UE adjusts the priority of inter-frequency 1 and inter-frequency 3 to priority 7, while the priority of the serving cell's frequency remains at 4 and is not adjusted. Furthermore, inter-frequency 2 and inter-frequency 4 do not support LP-WUS, therefore the UE does not adjust the priority of these two frequencies.

[0166] Alternatively, the first frequency may also include the frequency of the UE's serving cell. This can be understood as follows: if the serving cell supports LP-WUS, the first frequency may include the serving cell's frequency; if the serving cell does not support LP-WUS, the first frequency may not include the serving cell's frequency. For example, the first frequency may include one or more of inter-frequency, inter-system, or co-frequency frequencies. This indicates that when adjusting priorities, if the serving cell supports LP-WUS, the UE can adjust the priority of the serving cell's frequency, allowing the UE to either reselect to another cell or continue camping on the serving cell. For instance, the second priority is used for cell reselection, or the UE can adjust the priority of LP-WUS-supporting frequencies when performing cell reselection (or the UE performs cell reselection according to the adjusted priority), but not adjust the priority of LP-WUS-supporting frequencies when performing measurements (or the UE performs measurements according to the unadjusted priority). Based on the measurement results, the UE can determine the signal quality of the serving cell. If the serving cell's signal quality is good, for example, greater than or equal to a second threshold, then regardless of whether the serving cell supports LP-WUS, the first frequency may include the frequency of the UE's serving cell. That is, if the serving cell has good signal quality, and if the serving cell supports LP-WUS, the UE can increase the frequency priority of the serving cell. Therefore, when performing cell reselection, the UE may either reselect to another cell or continue camping on the serving cell, thus ensuring the UE camps on a cell with better signal quality as much as possible. The second threshold can be configured by the network device, determined by the UE itself, or predefined or pre-configured in the UE through a protocol.

[0167] Table 2 provides some examples of UE priority for adjusting frequencies supporting LP-WUS, with Table 2 using UE adjustment of different frequencies as an example.

[0168] Table 2

[0169] For example, inter-frequency 1, inter-frequency 3, and the serving cell's frequency in Table 2 all support LP-WUS. The UE adjusts the priority of inter-frequency 1, inter-frequency 3, and the serving cell's frequency to priority 7. However, inter-frequency 2 and inter-frequency 4 do not support LP-WUS, so the UE does not adjust the priority of these two frequencies.

[0170] The UE can determine whether a frequency supports LP-WUS based on the configuration of the network device (or the serving cell of the UE). For example, the network device (or the serving cell) can send second information indicating M frequencies, of which M1 frequencies support LP-WUS and M2 frequencies do not, M1 + M2 = M. Here, M is a positive integer, and M1 and M2 can both be positive integers. These M frequencies may include all or some of the frequencies to be tested by the UE. These M frequencies may include one or more of the following: inter-frequency frequencies, co-frequency frequencies, or inter-system frequencies. Upon receiving the second information, the UE can determine which frequencies support LP-WUS. A first frequency may belong to these M frequencies, for example, it may belong to M1 of the M frequencies. The second information may be included in a broadcast message or a unicast message. For example, if the second information is included in a broadcast message, it may be included in system information or other information. Taking the inclusion of the second information in a unicast message as an example, the second information may be included in an RRC-specific message (such as an RRC release message), or it may be included in other information. The second information may be the same as the aforementioned first information, or it may be different information.

[0171] For the UE, adjusting the priority of the first frequency is necessary because the UE determines or believes that the first frequency supports LP-WUS. For the UE, believing a frequency supports LP-WUS can mean that the frequency's capability supports LP-WUS; that is, as long as a frequency supports LP-WUS, the UE considers that frequency to support LP-WUS, regardless of the type of LP-WUS supported. In this case, a frequency's capability to support LP-WUS and the UE's belief that the frequency supports LP-WUS are equivalent. Optionally, the UE's belief that a frequency supports LP-WUS can also be understood as the UE believing that it can use the LP-WUS function of that frequency; conversely, the UE's belief that a frequency does not support LP-WUS can also be understood as the UE believing that it cannot use the LP-WUS function of that frequency.

[0172] Alternatively, for a UE, considering a frequency to support LP-WUS means that the type of LP-WUS supported by that frequency is the same as or overlaps with the type of LP-WUS supported by the UE. In this case, a frequency's capability to support LP-WUS and the UE's perception that the frequency supports LP-WUS may not be equivalent. For example, although a frequency may be capable of supporting LP-WUS, if the type of LP-WUS supported by that frequency is different from or does not overlap with the type of LP-WUS supported by the UE, the UE will still consider that frequency not to support LP-WUS. Determining whether a frequency supports LP-WUS by judging the LP-WUS type makes the judgment more accurate. Because if a frequency supports LP-WUS, but the type of LP-WUS supported by that frequency is different from or does not overlap with the type of LP-WUS supported by the UE, even if the UE reselects a cell under that frequency, it will not be able to receive LP-WUS in that cell. Therefore, this judgment method can encourage the UE to reselect a cell under a frequency with the same type of LP-WUS supported by the UE, so that the UE can receive LP-WUS in that cell, thus achieving energy saving.

[0173] The type of LP-WUS is represented, for example, by the type of WUR and / or by the waveform corresponding to the LP-WUS (or WUR). For example, different WUR types can be considered different LP-WUS types; or, different LP-WUS waveforms can be considered different LP-WUS types. A frequency can support one or more LP-WUS types (e.g., supporting one or more types of WURs, and / or supporting one or more LP-WUS waveforms), and the UE can also support one or more LP-WUS types. If the LP-WUS type supported by the UE is the same as or overlaps with the LP-WUS type supported by a frequency, the UE can consider that frequency to support LP-WUS; if the LP-WUS type supported by the UE is different from or does not overlap with the LP-WUS type supported by a frequency, the UE can consider that frequency not to support LP-WUS. For example, if the UE supports the first type of LP-WUS, and the first frequency also supports the first type of LP-WUS, the UE considers the first frequency to support LP-WUS. Optionally, the type of WUR may include, for example, on-off keying (OOK) receivers and / or orthogonal frequency division multiplexing (OFDM) receivers. Optionally, the waveform of LP-WUS may include, for example, long LP-WUS waveforms and / or short LP-WUS waveforms.

[0174] If the UE needs to determine whether a frequency supports LP-WUS based on the type of LP-WUS, the UE needs to know the types of LP-WUS supported by each frequency. Optionally, the second information can also indicate the types of LP-WUS supported by the first frequency. For example, the second information may indicate the types of LP-WUS supported by each of the N frequencies included in the first frequency, so that the UE can determine whether the N frequencies support LP-WUS. For instance, the second information may indicate the types of LP-WUS supported by M1 frequencies, and these M1 frequencies include the first frequency; therefore, the second information indicates the types of LP-WUS supported by the first frequency.

[0175] When a network device needs to send second information in the UE's serving cell, it first determines that M1 of the M frequencies support LP-WUS and M2 frequencies do not. For example, the network device corresponding to the serving cell can communicate with the network devices corresponding to the M frequencies to obtain information on whether some or all of the M frequencies support LP-WUS, as well as information such as the specific LP-WUS type supported by the frequencies that support LP-WUS. Thus, the serving cell can obtain the second information. Optionally, if the LP-WUS support status of a frequency changes (e.g., from supporting LP-WUS to not supporting LP-WUS, or from not supporting LP-WUS to supporting LP-WUS, or the supported LP-WUS type changes), the network device corresponding to that frequency can send information to the network device corresponding to the serving cell to indicate the change. The serving cell can then determine or update the LP-WUS support information for the M frequencies accordingly. Optionally, after the network device sends the second information in the UE's serving cell, if the support status of LP-WUS for any of the M frequencies is updated, the network device can reconfigure the updated support information to the UE.

[0176] Optionally, the method may further include S303, whereby the UE sets the priority of the second frequency to the third priority. Optionally, the second frequency may belong to M frequencies, for example, the M frequencies may include the first and second frequencies. The third priority may be used to perform cell reselection and / or measurement. The second frequency may be a frequency that the UE considers not to support LP-WUS.

[0177] The original priority of the second frequency, for example, is the fourth priority, which may be indicated by the first information. For example, the first information indicates that the priority of the second frequency is the fourth priority, which is the priority configured by the network device for the UE to perform measurements and / or cell reselection.

[0178] The third priority can be lower than or equal to the fourth priority. This can be understood as the UE lowering the priority of frequencies that do not support LP-WUS, so that during cell reselection, the UE is less likely to reselect cells on frequencies that do not support LP-WUS, and instead reselects cells on frequencies that do support LP-WUS, thus achieving energy savings. Optionally, the third priority can be the lowest priority. For example, if there are eight priorities, from 0 to 7, with priority 0 being the lowest, then the third priority could be priority 0. Setting the priority of frequencies that do not support LP-WUS to the lowest priority reduces the probability of the UE reselecting cells on those frequencies.

[0179] The second frequency may include K frequencies, where K is a positive integer. For the K frequencies, the third priority of different frequencies may be the same or different. For example, if the third priority of different frequencies among the K frequencies is the same, this third priority may be the lowest priority. Alternatively, if the third priorities of different frequencies among the K frequencies are different, then the third priority of a certain frequency among the K frequencies may be the lowest priority, or it may be any priority that is lower than or equal to the fourth priority of that frequency.

[0180] Optionally, when setting a third priority for the second frequency, the UE can refer to a fourth priority. For example, if the UE determines a fourth priority based on the first information, it can set the priority of the second frequency to a priority lower than or equal to the fourth priority; this third priority is the third priority. Alternatively, the UE can set a third priority for the second frequency without referring to the fourth priority. For example, although the UE receives the first information, it does not determine the fourth priority based on it. It can be assumed that the UE is unaware of the fourth priority, and the UE can directly set the priority of the second frequency to the lowest priority (which is the third priority). This method is simpler for the UE to implement.

[0181] As an optional implementation, the fourth priority is not limited; for example, the fourth priority can be higher than, equal to, or lower than the frequency priority of the serving cell. This can be understood as follows: regardless of whether the original priority of a frequency is higher than, equal to, or lower than the frequency priority of the serving cell, as long as the frequency does not support LP-WUS, the UE can adjust the priority of that frequency to the third priority.

[0182] Alternatively, the fourth priority can be higher than the frequency priority of the serving cell. This can be understood as follows: for frequencies whose original priority was higher than the serving cell's frequency priority, if that frequency does not support LP-WUS, the UE can adjust its priority to the third priority; while for frequencies whose original priority was equal to or lower than the serving cell's frequency priority, the UE can leave that frequency's priority unchanged regardless of whether it supports LP-WUS. Specifically, if the fourth priority is not restricted, the UE can adjust the priority of all frequencies that do not support LP-WUS to the third priority. During cell reselection, if the UE cannot select a suitable cell among those supporting LP-WUS, it may continue to select among those that do not support LP-WUS. In this case, the priorities of cells that do not support LP-WUS are all low, which is disadvantageous for the UE's selection. However, if the UE simply lowers the priority of frequencies that do not support LP-WUS among the higher priority frequencies, when performing cell reselection, if the UE cannot select a suitable cell among the LP-WUS-supporting cells, it will continue to select among the non-LP-WUS-supporting cells. The priority of the non-LP-WUS-supporting cells may not have been lowered. For example, the priority of the non-LP-WUS-supporting cells may be equal to or lower than the priority of the serving cell's frequency, which is beneficial for the UE to select a suitable cell.

[0183] Optionally, the second frequency may exclude the frequency of the UE's serving cell. This can be understood as the second frequency excluding the serving cell's frequency regardless of whether the serving cell supports LP-WUS. For example, the second frequency may include inter-frequency and / or inter-system frequencies, but exclude co-frequency frequencies. This indicates that when adjusting priorities, the UE can choose not to adjust the serving cell's frequency priority regardless of whether the serving cell supports LP-WUS, making it more likely for the UE to reselect to another cell. For instance, the third priority is used for cell reselection, or the UE can adjust the priority of LP-WUS-supporting frequencies when performing cell reselection (or the UE performs cell reselection according to the adjusted priority), but not adjust the priority of LP-WUS-supporting frequencies when performing measurements (or the UE performs measurements according to the unadjusted priority). The UE can then determine the serving cell's signal quality based on the measurement results. If the serving cell's signal quality is good, for example, greater than or equal to a second threshold, then the second frequency may exclude the UE's serving cell's frequency regardless of whether the serving cell supports LP-WUS. That is, if the signal quality of the serving cell is good, the UE may not lower the frequency priority of the serving cell even if the serving cell does not support LP-WUS. As a result, the UE may continue to camp on the serving cell when performing cell reselection, so that the UE can camp on the cell with better signal quality as much as possible.

[0184] Alternatively, the second frequency may also include the frequency of the UE's serving cell. This can be understood as follows: if the serving cell does not support LP-WUS, the second frequency may include the serving cell's frequency; if the serving cell supports LP-WUS, the second frequency may not include the serving cell's frequency. For example, the second frequency may include one or more of inter-frequency, inter-system, or co-frequency frequencies. This indicates that when adjusting priorities, if the serving cell does not support LP-WUS, the UE can adjust the priority of the serving cell's frequency, making it more likely that the UE will reselect to a cell that supports LP-WUS. For example, a third priority is used for cell reselection, or the UE can adjust the priority of LP-WUS-supporting frequencies when performing cell reselection (or the UE performs cell reselection according to the adjusted priority), but will not adjust the priority of LP-WUS-supporting frequencies when performing measurements (or the UE performs measurements according to the unadjusted priority). The UE can then determine the signal quality of the serving cell based on the measurement results. If the serving cell's signal quality is poor, for example, if the signal quality is less than or equal to a first threshold, then if the serving cell does not support LP-WUS, the second frequency may include the frequency of the UE's serving cell. That is, if the signal quality of the serving cell is poor, and if the serving cell does not support LP-WUS, the UE can lower the frequency priority of the serving cell, so that the UE is more likely to reselect a cell that supports LP-WUS when performing cell reselection.

[0185] For the UE, adjusting the priority of the second frequency is necessary because the UE determines or believes that the second frequency does not support LP-WUS. For the UE, believing a frequency does not support LP-WUS can mean that the frequency's capabilities do not support LP-WUS; that is, if a frequency's capabilities do not support LP-WUS, the UE considers that frequency to not support LP-WUS, regardless of the type of LP-WUS supported by the frequency. In this case, a frequency's capabilities not supporting LP-WUS and the UE's belief that the frequency does not support LP-WUS are equivalent.

[0186] Alternatively, for a UE, believing a frequency does not support LP-WUS means that the type of LP-WUS supported by that frequency is different from or has no overlap with the type of LP-WUS supported by the UE. In this case, a frequency's capability not supporting LP-WUS and the UE's belief that the frequency does not support LP-WUS may not be equivalent. For example, if a frequency's capability does not support LP-WUS, the UE will believe that the frequency does not support LP-WUS; or, although a frequency's capability supports LP-WUS, if the type of LP-WUS supported by that frequency is different from or has no overlap with the type of LP-WUS supported by the UE, the UE will still believe that the frequency does not support LP-WUS. Determining whether a frequency supports LP-WUS by judging the LP-WUS type can make the judgment result more accurate.

[0187] A frequency can support one or more LP-WUS types (e.g., supporting one or more types of WUR, and / or supporting one or more LP-WUS waveforms), and a UE can also support one or more LP-WUS types. If the LP-WUS types supported by the UE are the same as or overlap with the LP-WUS types supported by a frequency, the UE can consider that frequency to support LP-WUS; if the LP-WUS types supported by the UE are different from or do not overlap with the LP-WUS types supported by a frequency, the UE can consider that frequency to not support LP-WUS. The second frequency includes K frequencies. For example, if none of the K frequencies support LP-WUS (these K frequencies belong to M2 out of M frequencies), then the UE considers that the K frequencies do not support LP-WUS; or, among the K frequencies, some frequencies do not support LP-WUS (these frequencies belong to M1 out of M frequencies), and the remaining frequencies support LP-WUS (these remaining frequencies belong to M2 out of M frequencies), but the LP-WUS type supported by the remaining frequencies is different from or has no overlap with the LP-WUS type supported by the UE, therefore the UE considers that the K frequencies do not support LP-WUS; or, all K frequencies support LP-WUS (the K frequencies belong to M1 out of M frequencies), but the LP-WUS type supported by the K frequencies is different from or has no overlap with the LP-WUS type supported by the UE, therefore the UE considers that the K frequencies do not support LP-WUS.

[0188] Optionally, the first frequency supports LP-WUS, which may specifically include the first frequency itself supporting LP-WUS. In this case, which cells under the first frequency support LP-WUS is not discussed, or it can be assumed that all cells under the first frequency support LP-WUS. This can be understood as whether LP-WUS support is frequency-level or frequency-granular; that is, whether LP-WUS is supported refers to whether a specific frequency supports LP-WUS.

[0189] Alternatively, the first frequency may support LP-WUS. Specifically, this could mean that cells within the first frequency support LP-WUS. In this case, LP-WUS support is understood to be at the cell level or granular. That is, whether LP-WUS is supported refers to whether a specific cell supports LP-WUS, not whether a specific frequency supports LP-WUS. Regarding whether a cell supports LP-WUS, please refer to the previous section on frequency support (e.g., as mentioned earlier, frequency support could mean that the frequency's capability supports LP-WUS, or that the frequency is configured, enabled, activated, or uses LP-WUS). Similarly, regarding whether a cell does not support LP-WUS, please refer to the previous section on frequency non-support (e.g., as mentioned earlier, frequency non-support could mean that the frequency's capability does not support LP-WUS, or that the frequency is not configured, enabled, activated, or does not use LP-WUS).

[0190] Cells in the first frequency support LP-WUS, which can be implemented in different ways. Optionally, LP-WUS support in the first frequency can mean that all cells in the first frequency support LP-WUS. In this case, LP-WUS support in the first frequency can specifically include all cells in the first frequency supporting LP-WUS. For example, if all cells in the first frequency support LP-WUS, then the first frequency can be considered to support LP-WUS; if at least one cell in the first frequency does not support LP-WUS, then the first frequency can be considered to not support LP-WUS.

[0191] Alternatively, "cells in the first frequency support LP-WUS" can mean that at least one cell in the first frequency supports LP-WUS. This "at least one cell" can refer to all or some of the cells in the first frequency. For example, if at least one cell in the first frequency supports LP-WUS, then the first frequency is considered to support LP-WUS; if none of the cells in the first frequency support LP-WUS, then the first frequency is considered not to support LP-WUS.

[0192] Optionally, the LP-WUS types supported by the first frequency may specifically include LP-WUS types supported by the first frequency itself, or it can be understood that the supported LP-WUS types are frequency-level. In this case, the LP-WUS types supported by cells under the first frequency are not considered, or it can be considered that the LP-WUS types supported by the first frequency are the LP-WUS types supported by every cell under the first frequency. This can be understood as the supported LP-WUS types being frequency-level, or frequency-granular; that is, the supported LP-WUS types refer to the LP-WUS types supported by a specific frequency.

[0193] Alternatively, the LP-WUS types supported by the first frequency can specifically include the LP-WUS types supported by cells within the first frequency. In this case, it can be understood that the supported LP-WUS types are at the cell level or at the cell granularity; that is, the supported LP-WUS types refer to the LP-WUS types supported by a specific cell, rather than the LP-WUS types supported by the frequency.

[0194] If LP-WUS support is frequency-level, the second information can optionally indicate whether a specific frequency supports LP-WUS, for example, indicating that each of the M1 frequencies supports LP-WUS. This can be understood as the second information indicating LP-WUS support at the frequency level, rather than indicating whether the cell at that frequency supports LP-WUS.

[0195] Alternatively, if LP-WUS support is at the cell level, the second information may optionally indicate whether a certain frequency supports LP-WUS. Specifically, the second information may indicate whether each cell in some or all of the cells at that frequency supports LP-WUS. This can be understood as the second information indicating LP-WUS support at the cell level. In this case, the second information does not indicate whether a certain frequency supports LP-WUS, but rather whether the cells at that frequency support LP-WUS. The UE can optionally determine whether a certain frequency supports LP-WUS based on the indication of the second information (for example, if all cells at that frequency support LP-WUS, then the frequency is considered to support LP-WUS; if at least one cell at that frequency does not support LP-WUS, then the frequency is considered not to support LP-WUS; or, if at least one cell at that frequency supports LP-WUS, then the frequency is considered to support LP-WUS; if none of the cells at that frequency support LP-WUS, then the frequency is considered not to support LP-WUS). For example, the second information indicates M frequencies, where P cells exist under one of these frequencies. The second information can also indicate that P1 of the P cells support LP-WUS, and that P2 of the P cells do not support LP-WUS, where P1 + P2 = P. A similar indication method can be used for the cells under each of the M frequencies.

[0196] If the second information indicates whether LP-WUS is supported at the frequency level, and the second information is to indicate the LP-WUS type, optionally, the second information can indicate the LP-WUS type supported at a specific frequency. This can be understood as the second information indicating the supported LP-WUS type at the frequency level, rather than indicating the LP-WUS type supported by a specific cell at that frequency.

[0197] Alternatively, if the second information indicates whether LP-WUS is supported at the cell level, and the second information is to indicate the LP-WUS type, optionally, the second information can indicate the LP-WUS types supported by cells at a certain frequency. This can be understood as the second information indicating the supported LP-WUS types at the cell level, but not the LP-WUS types supported by the frequency to which the cell belongs. For example, for any one of M1 frequencies, the second information can indicate the LP-WUS types supported by some or all of the cells at that frequency. For instance, if the second information indicates M frequencies, and one of those frequencies has P cells, the second information can also indicate that P1 of the P cells support LP-WUS, and that P2 of the P cells do not support LP-WUS; additionally, the second information can also indicate the LP-WUS type supported by each of the P1 cells. Where at least one cell at the first frequency supports LP-WUS, this can be understood as at least one cell at the first frequency supporting the first type of LP-WUS, and the first type of LP-WUS is also supported by the UE.

[0198] A cell being configured with LP-WUS or LP-WUS functionality can mean either that the network device has configured LP-WUS or LP-WUS functionality for that cell, or that the network device can support the use of LP-WUS or LP-WUS functionality in that cell. If a cell is configured with LP-WUS or LP-WUS functionality, for any UE using that cell or camped on that cell, the cell's capability is considered to support LP-WUS or LP-WUS functionality (although specific UEs supporting different LP-WUS types may perceive the cell as supporting or not supporting LP-WUS functionality). A cell not being configured with LP-WUS or LP-WUS functionality can mean either that the network device has not configured LP-WUS or LP-WUS functionality for that cell, or that the network device cannot use LP-WUS or LP-WUS functionality in that cell. If a cell is not configured with LP-WUS or LP-WUS functionality, for any UE using that cell or camped on that cell, the cell's capability is not considered to support LP-WUS or LP-WUS functionality.

[0199] Optionally, the second priority is used to perform cell reselection. This can be understood as using the second priority when determining the criteria for cell reselection. For example, for a UE, if all cells in the first frequency support LP-WUS or support the first type of LP-WUS, then all these cells can be treated equally during cell reselection. Alternatively, if at least one cell in the first frequency supports LP-WUS or supports the first type of LP-WUS, while the remaining cells do not support LP-WUS or do not support the first type of LP-WUS, then during cell reselection, the UE can prioritize reselecting to that at least one cell, or prioritize determining whether to reselect to that at least one cell. For example, for a UE, if multiple cells (corresponding to the same frequency or different frequencies) meet the cell reselection criteria, then the cell with the highest priority among those supporting LP-WUS or supporting the first type of LP-WUS, and ranked highest according to the R criterion, can be selected. This can also be understood as prioritizing the selection of cells supporting LP-WUS or supporting the first type of LP-WUS.

[0200] Optionally, the technical solutions of this application embodiment can be applied to measurement and / or cell reselection. For example, for a first frequency, the UE can use the first priority instead of the second priority during measurement (e.g., the UE does not adjust the priority during measurement), and can use the second priority instead of the first priority during cell reselection (e.g., the UE adjusts the priority during cell reselection). In this case, the UE does not need to measure more high-priority frequencies, thus not increasing the power consumption introduced by measurement, but only adjusting the priority during cell reselection, so that the UE can reselect to a cell under a frequency that supports LP-WUS as much as possible when performing cell reselection, so as to achieve better energy saving effect; or, the UE can use the second priority instead of the first priority in both the measurement process and the cell reselection process (e.g., the UE adjusts the priority during measurement). As another example, for a second frequency, the UE can use the fourth priority instead of the third priority during measurement, and use the third priority instead of the fourth priority during cell reselection; or, the UE can use the third priority instead of the fourth priority in both the measurement process and the cell reselection process.

[0201] Optionally, if there are frequencies that support LP-WUS, for example, if the M frequencies indicated by the second information include frequencies that support LP-WUS, then the UE can adopt the scheme of the present application embodiment; however, if there are no frequencies that support LP-WUS, for example, if none of the M frequencies support LP-WUS, then the UE can choose not to adopt the scheme of the present application embodiment, but instead perform measurement and cell reselection according to the original priority of the M frequencies (for example, the priority indicated by the first information).

[0202] Optionally, the UE in this application embodiment can be a UE with WUR capability. Having WUR capability can also be described as supporting LP-WUS, having LP-WUS detection capability, being configured with WUR or LP-WUS functions, having energy-saving needs or interests, having WUR or LP-WUS functions enabled, or having LP-WUS detection enabled, or other descriptive methods. This application embodiment does not impose limitations. Correspondingly, some UEs may not have WUR capability. Such UEs may not apply the scheme of this application embodiment, but can perform measurement and cell reselection according to traditional schemes. The absence of WUR capability can also be described as follows: it does not support LP-WUS, does not have LP-WUS detection capability, or is not configured with WUR or LP-WUS functions, or has no energy-saving preference or interest, or WUR or LP-WUS functions are not enabled, or LP-WUS detection is not enabled, or other descriptions are possible. This application's embodiments do not impose limitations. In various embodiments of this application, "detection" can be either "detect" or "monitor".

[0203] For example, if a UE reselects to a first cell using the scheme in this embodiment, the UE can camp on the first cell. The first cell may support LP-WUS, or the LP-WUS type supported by the first cell may be the same as or overlap with the LP-WUS type supported by the UE. The first cell may or may not be the UE's original serving cell. If the first cell is not the UE's original serving cell, then the first cell and the UE's original serving cell may belong to the same network device or different network devices.

[0204] The UE can detect LP-WUS in the first cell. For example, if the UE receives LP-WUS from the first cell, this LP-WUS is referred to as the first LP-WUS. The first LP-WUS can be used to wake up the UE. For example, the first LP-WUS includes wake-up indication information, which can be used to wake up the UE. In this case, the UE can set the priority of the first frequency to the first priority, and / or set the priority of the second frequency to the fourth priority. Optionally, if the UE determines that it is being woken up based on the first LP-WUS, it can adjust the priority of the corresponding frequency, setting the priority of the first frequency to the first priority, and / or setting the priority of the second frequency to the fourth priority; if the UE determines that it is not being woken up based on the first LP-WUS, or has not received LP-WUS, it can choose not to adjust the priority of the corresponding frequency. Alternatively, if the UE determines it has been woken up based on the first LP-WUS, the UE can continue to detect paging messages in the first cell. Upon receiving a paging message, if it determines that the UE has been paged (e.g., the paging message includes the UE's identifier), the UE can adjust the priority of the corresponding frequency, setting the priority of the first frequency to the first priority, and / or setting the priority of the second frequency to the fourth priority. If it determines that the UE has not been paged (e.g., the paging message does not include the UE's identifier), the UE can choose not to adjust the priority of the corresponding frequency. Determining that the UE has been paged can also be understood as the UE determining that it wants to initiate a random access procedure to access the network device.

[0205] The reason is that if a UE is woken up by the first LP-WUS, it indicates that the UE may be paged, and the UE needs to enter RRC connected state; or if the UE determines it is paged based on the paging message, the UE needs to enter RRC connected state. The UE reselects to the first cell to detect LP-WUS in the first cell, or because the first cell supports LP-WUS, not because the first cell is advantageous for communication for UEs in RRC connected state. If a UE wants to enter RRC connected state, it should consider entering a cell that is advantageous for communication in RRC connected state. Furthermore, during cell reselection, a large number of UEs may reselect to the first cell that supports LP-WUS. If multiple UEs want to enter RRC connected state in the first cell, it may cause excessive load on the first cell, or even congestion. Therefore, if a UE is woken up by the first LP-WUS, or determines it is being paged, it can perform cell reselection again, and then enter RRC connected state in the new cell. To reselect a cell that is more conducive to UE communication in RRC connected state, the UE can adjust the priority of the first frequency and / or the second frequency back to its original priority. This makes it more likely that the UE will reselect a cell with better communication quality while avoiding excessive load on the first cell. For example, after adjusting the priority of the first frequency and / or the second frequency, the UE performs cell reselection and enters the second cell. The UE can then enter RRC connected state in the second cell to communicate. If the UE is woken up by the first LP-WUS or determines it is being paged according to a paging message, the UE's action is to adjust the priority of the corresponding frequency. After adjusting the frequency priority, cell reselection may or may not occur. The UE still determines whether to perform cell reselection according to the existing cell reselection process. Therefore, the technical solution of this application embodiment enables the UE to detect LP-WUS to achieve UE energy saving and allows the UE to enter RRC connected state in a cell with better communication quality, thereby improving the UE's communication quality.

[0206] In this embodiment, the UE can set the frequency priority according to whether it supports LP-WUS, so that the UE has a greater probability of selecting a cell with a frequency that supports LP-WUS when performing cell reselection. In this cell, the UE can receive LP-WUS, thereby achieving energy saving.

[0207] This application provides a second communication method, please refer to Figure 4, which is a flowchart of the method.

[0208] S401, The network device sends the first information. Correspondingly, the UE receives the first information.

[0209] The first information may indicate the priority of the second frequency, such as fourth priority. For example, the first information may indicate the second frequency by including information about the second frequency, which may include information about the fourth priority, indicating that the second frequency has the fourth priority. The second frequency may include K frequencies, where K is a positive integer. For example, these K frequencies may be all or some of the frequencies to be measured by the UE. Alternatively, the first frequency may be a frequency from a neighboring cell, which may include one or more of the following: same-frequency frequencies, different-frequency frequencies, or frequencies from different systems. By measuring the frequencies to be measured, the UE can perform cell reselection based on the measurement results.

[0210] The fourth priority can be the original priority of the second frequency, which is the priority configured by the network device for the UE to perform measurements and / or cell reselection. For example, the fourth priority can be higher than, equal to, or lower than the priority of the frequency corresponding to the UE's serving cell.

[0211] S402, The UE sets the priority of the second frequency to the third priority.

[0212] The third priority can be used to perform measurements and / or cell reselection. For example, the third priority can be used to perform measurements and / or cell reselection; or, the fourth priority can be used to perform measurements, and the third priority can be used to perform cell reselection. Here, measurement can be understood as performing RRM measurements on the frequencies of the neighboring cells to be measured. This measurement is used for cell reselection; for example, the measurement results obtained through this measurement can be used for cell reselection. The second frequency can be a frequency that the UE believes does not support LP-WUS. For information on whether the UE believes a frequency supports LP-WUS, and whether a frequency's capability supports LP-WUS, please refer to the relevant description in the embodiment shown in Figure 3.

[0213] The third priority can be lower than or equal to the fourth priority. This can be understood as the UE lowering the priority of frequencies that do not support LP-WUS, so that during cell reselection, the UE is less likely to reselect cells on frequencies that do not support LP-WUS, and instead reselects cells on frequencies that do support LP-WUS, thus achieving energy savings. Optionally, the third priority can be the lowest priority. For example, if there are eight priorities, from 0 to 7, with priority 0 being the lowest, then the third priority could be priority 0. Setting the priority of frequencies that do not support LP-WUS to the lowest priority reduces the probability of the UE reselecting cells on those frequencies.

[0214] The second frequency may include K frequencies, where K is a positive integer. For the K frequencies, the third priority of different frequencies may be the same or different. For example, if the third priority of different frequencies among the K frequencies is the same, then the third priority may be the lowest priority. Alternatively, if the third priorities of different frequencies among the K frequencies are different, then the third priority of a certain frequency among the K frequencies may be the lowest priority, or it may be any priority lower than or equal to the fourth priority of that frequency.

[0215] Optionally, when setting a third priority for the second frequency, the UE can refer to a fourth priority. For example, if the UE determines a fourth priority based on the first information, it can set the priority of the second frequency to a priority lower than or equal to the fourth priority; this third priority is the third priority. Alternatively, the UE can set a third priority for the second frequency without referring to the fourth priority. For example, although the UE receives the first information, it does not determine the fourth priority based on it. It can be assumed that the UE is unaware of the fourth priority, and the UE can directly set the priority of the second frequency to the lowest priority (which is the third priority). This method is simpler for the UE to implement.

[0216] As an optional implementation, the fourth priority is not limited; for example, the fourth priority can be higher than, equal to, or lower than the frequency priority of the serving cell. This can be understood as follows: regardless of whether the original priority of a frequency is higher than, equal to, or lower than the frequency priority of the serving cell, as long as the frequency does not support LP-WUS, the UE can adjust the priority of that frequency to the third priority.

[0217] Alternatively, the fourth priority can be higher than the frequency priority of the serving cell. This can be understood as follows: for a frequency whose original priority was higher than the frequency priority of the serving cell, if that frequency does not support LP-WUS, the UE can adjust the frequency's priority to the third priority; while for a frequency whose original priority was equal to or lower than the frequency priority of the serving cell, regardless of whether that frequency supports LP-WUS, the UE can choose not to adjust the frequency's priority. For details on this, please refer to the relevant description of the embodiment shown in Figure 3.

[0218] Optionally, the second frequency may not include the frequency of the UE's serving cell. This means that regardless of whether the serving cell supports LP-WUS, the second frequency does not include the serving cell's frequency. For example, the second frequency may include inter-frequency frequencies and / or inter-system frequencies, but exclude co-frequency frequencies. Alternatively, the second frequency may also include the frequency of the UE's serving cell. This means that if the serving cell does not support LP-WUS, the second frequency may include the serving cell's frequency; if the serving cell supports LP-WUS, the second frequency may not include the serving cell's frequency. For example, the second frequency may include one or more of inter-frequency frequencies, inter-system frequencies, or co-frequency frequencies. This indicates that when adjusting priorities, if the serving cell does not support LP-WUS, the UE can adjust the priority of the serving cell's frequency, making it more likely that the UE will reselect to a cell that supports LP-WUS. For details on this part, please refer to the relevant description of the embodiment shown in Figure 3.

[0219] For the UE, adjusting the priority of the second frequency is necessary because the UE determines or believes that the second frequency does not support LP-WUS. For the UE, believing a frequency does not support LP-WUS can mean that the frequency's capability does not support the LP-WUS function. That is, if a frequency's capability does not support LP-WUS, the UE considers that frequency to not support LP-WUS, regardless of the type of LP-WUS supported by the frequency. In this case, a frequency's capability not supporting LP-WUS and the UE's belief that the frequency does not support LP-WUS are equivalent.

[0220] Alternatively, for the UE, considering a frequency as not supporting LP-WUS means that the type of LP-WUS supported by that frequency is different from or has no overlap with the type of LP-WUS supported by the UE. In this case, the fact that a frequency's capability does not support LP-WUS and the UE's belief that the frequency does not support LP-WUS may not be equivalent. For example, if a frequency's capability does not support LP-WUS, the UE will consider that frequency to be unsupported; or, although a frequency's capability supports LP-WUS, if the type of LP-WUS supported by that frequency is different from or has no overlap with the type of LP-WUS supported by the UE, the UE will still consider that frequency to be unsupported. Determining whether a frequency supports LP-WUS by judging the LP-WUS type can make the judgment result more accurate. For a description of this part and the LP-WUS types, please refer to the embodiment shown in Figure 3.

[0221] The UE can determine whether a frequency supports LP-WUS based on the configuration of the network device (or the serving cell of the UE). For example, the network device (or the serving cell) can send second information indicating M frequencies, of which M1 frequencies support LP-WUS and M2 frequencies do not, M1 + M2 = M. Here, M is a positive integer, M1 can be an integer greater than or equal to 0, and M2 can also be an integer greater than or equal to 0. These M frequencies may include all or some of the frequencies to be tested by the UE. These M frequencies may include one or more of the following: inter-frequency frequencies, intra-frequency frequencies, or inter-system frequencies. Upon receiving the second information, the UE can determine which frequencies support LP-WUS. The second frequency belongs to these M frequencies, for example, it belongs to the M1 frequencies and / or the M2 frequencies. The second information may be included in a broadcast message or a unicast message. For example, if the second information is included in a broadcast message, it may be included in system information, or it may be included in other information. The second information may be the same as the aforementioned first information, or it may be different information.

[0222] Optionally, the second information may also indicate the type of LP-WUS supported by the M1 frequencies. For example, the second information indicates the type of LP-WUS supported by each of the M1 frequencies, so that the UE can determine whether the second frequency supports LP-WUS. The second frequency includes K frequencies. For example, if none of the K frequencies support LP-WUS (these K frequencies belong to M2 out of M frequencies), then the UE considers that the K frequencies do not support LP-WUS; or, among the K frequencies, some frequencies do not support LP-WUS (these frequencies belong to M1 out of M frequencies), and the remaining frequencies support LP-WUS (these remaining frequencies belong to M2 out of M frequencies), but the LP-WUS type supported by the remaining frequencies is different from or has no overlap with the LP-WUS type supported by the UE, therefore the UE considers that the K frequencies do not support LP-WUS; or, all K frequencies support LP-WUS (the K frequencies belong to M1 out of M frequencies), but the LP-WUS type supported by the K frequencies is different from or has no overlap with the LP-WUS type supported by the UE, therefore the UE considers that the K frequencies do not support LP-WUS.

[0223] If the serving cell needs to send the second information, it must first determine whether M1 of the M frequencies support LP-WUS and whether M2 frequencies do not. For example, the network device corresponding to the serving cell can communicate with the network devices corresponding to the M frequencies to obtain information on whether some or all of the M frequencies support LP-WUS, and also to obtain information such as the specific LP-WUS type supported by the frequencies that support LP-WUS. Thus, the serving cell can obtain the second information. For details on this part, please refer to the relevant description of the embodiment shown in Figure 3.

[0224] Optionally, the method may also include S403, whereby the UE sets the priority of the first frequency to the second priority.

[0225] The second priority can be used to perform measurements and / or cell reselection. The first frequency can support LP-WUS; optionally, the first frequency can be a frequency that the UE believes supports LP-WUS or LP-WUS functionality. For information on whether the UE believes a frequency supports LP-WUS or LP-WUS functionality, please refer to the relevant descriptions in the preceding text or the embodiments shown in Figure 3. Optionally, the first frequency can belong to the M frequencies indicated by the second information, for example, the M frequencies include the first frequency and the second frequency. For example, the first frequency belongs to M1 frequencies out of the M frequencies.

[0226] The second priority can be higher than or equal to the first priority. This can be understood as the UE increasing the priority of frequencies supporting LP-WUS, so that during cell reselection, the UE is more likely to reselect cells on frequencies supporting LP-WUS, thus achieving energy savings. Optionally, the second priority can be the highest priority. For example, if there are eight priorities, from 0 to 7, with priority 7 being the highest, then the second priority could be priority 7. Setting the priority of frequencies supporting LP-WUS to the highest priority increases the probability of the UE reselecting cells on those frequencies.

[0227] The first frequency may include N frequencies, where N is a positive integer. For the N frequencies, the second priority of different frequencies may be the same or different. For example, if the second priority of different frequencies among the N frequencies is the same, then the second priority may be the highest priority. Alternatively, if the second priorities of different frequencies among the N frequencies are different, then the second priority of a certain frequency among the N frequencies may be the highest priority, or it may be any priority that is higher than or equal to the first priority of that frequency.

[0228] Optionally, the UE can refer to the first priority when setting a second priority for the first frequency. For example, if the UE determines the first priority based on the first information, it can set the priority of the first frequency to a priority higher than or equal to the first priority; this priority is the second priority. Alternatively, the UE can set the second priority for the first frequency without referring to the first priority. For example, although the UE receives the first information, it does not determine the first priority based on it. It can be assumed that the UE is unaware of the first priority, and the UE can directly set the priority of the first frequency to the highest priority (this highest priority is the second priority). This method is simpler for the UE to implement.

[0229] Optionally, the first frequency may not include the frequency of the UE's serving cell. This can be understood as the first frequency excluding the serving cell's frequency regardless of whether the serving cell supports LP-WUS. For example, the first frequency may include inter-frequency frequencies and / or inter-system frequencies, but exclude co-frequency frequencies. This indicates that when adjusting priorities, the UE can choose not to adjust the serving cell's frequency priority regardless of whether the serving cell supports LP-WUS, making it more likely for the UE to reselect to another cell. Alternatively, the first frequency may also include the frequency of the UE's serving cell. This can be understood as follows: if the serving cell supports LP-WUS, the first frequency may include the serving cell's frequency; if the serving cell does not support LP-WUS, the first frequency may not include the serving cell's frequency. For example, the first frequency may include one or more of inter-frequency frequencies, inter-system frequencies, or co-frequency frequencies. This indicates that when adjusting priorities, if the serving cell supports LP-WUS, the UE can also adjust the serving cell's frequency priority, making it possible for the UE to either reselect to another cell or continue camping on the serving cell. For more details on this part, please refer to the relevant description of the embodiment shown in Figure 3.

[0230] For the UE, adjusting the priority of the first frequency is necessary because the UE determines or believes that the first frequency supports LP-WUS. For the UE, believing a frequency supports LP-WUS can mean that the frequency's capability supports the LP-WUS function; that is, as long as a frequency's capability supports LP-WUS, the UE considers that frequency to support LP-WUS, regardless of the specific LP-WUS type supported. In this case, a frequency's capability supporting LP-WUS and the UE's belief that the frequency supports LP-WUS are equivalent.

[0231] Alternatively, for a UE, considering a frequency to support LP-WUS means that the type of LP-WUS supported by that frequency is the same as or overlaps with the type of LP-WUS supported by the UE. In this case, a frequency's capability to support LP-WUS and the UE's perception that the frequency supports LP-WUS may not be equivalent. For example, although a frequency may be capable of supporting LP-WUS, if the type of LP-WUS supported by that frequency is different from or does not overlap with the type of LP-WUS supported by the UE, the UE will still consider that the frequency not to support LP-WUS. Determining whether a frequency supports LP-WUS by judging the LP-WUS type can make the judgment more accurate.

[0232] A frequency can support one or more LP-WUS types (e.g., supporting one or more types of WUR, and / or supporting one or more LP-WUS waveforms), and a UE can also support one or more LP-WUS types. If the LP-WUS type supported by the UE is the same as or overlaps with the LP-WUS type supported by a frequency, the UE can consider that frequency to support LP-WUS; if the LP-WUS type supported by the UE is different from or does not overlap with the LP-WUS type supported by a frequency, the UE can consider that frequency not to support LP-WUS. For example, if the UE supports the first type of LP-WUS, and the first frequency also supports the first type of LP-WUS, the UE considers the first frequency to support LP-WUS.

[0233] Optionally, the second information may also indicate the types of LP-WUS supported by the M1 frequencies, where M1 frequencies include N frequencies. Therefore, the second information indicates the types of LP-WUS supported by the N frequencies. For example, the second information indicates the type of LP-WUS supported by each of the N frequencies, so that the UE can determine whether the N frequencies support LP-WUS, such as whether the types of LP-WUS supported by the N frequencies are the same as or overlap with the types of LP-WUS supported by the UE.

[0234] The first frequency supporting LP-WUS can mean that the first frequency itself supports LP-WUS, or it can be understood as whether or not LP-WUS support is frequency-level; alternatively, the first frequency supporting LP-WUS can also mean that the cells under the first frequency support LP-WUS, or it can be understood as whether or not LP-WUS support is cell-level. The LP-WUS type supported by the first frequency can mean that the first frequency itself supports an LP-WUS type, or it can be understood as the LP-WUS type support being frequency-level; alternatively, the LP-WUS type supported by the first frequency can mean that the LP-WUS type support being cell-level. For more details on this, please refer to the relevant description of the embodiment shown in Figure 3.

[0235] Correspondingly, if LP-WUS support is frequency-level, optionally, the second information can indicate whether a certain frequency supports LP-WUS, for example, indicating that each of M1 frequencies supports LP-WUS. This can be understood as the second information indicating whether LP-WUS is supported at the frequency level, rather than indicating whether the cells at that frequency support LP-WUS. Alternatively, if LP-WUS support is cell-level, optionally, the second information indicates whether a certain frequency supports LP-WUS, specifically including whether the second information indicates whether each cell in some or all of the cells at that frequency supports LP-WUS. For details on this part, please refer to the relevant description of the embodiment shown in Figure 3.

[0236] If the second information indicates whether LP-WUS is supported at the frequency level, and the second information is to indicate the LP-WUS type, optionally, the second information can indicate the LP-WUS types supported at a specific frequency. This can be understood as the second information indicating the supported LP-WUS types at the frequency level, but not indicating the LP-WUS types supported by a specific cell at that frequency. Alternatively, if the second information indicates whether LP-WUS is supported at the cell level, and the second information is to indicate the LP-WUS type, optionally, the second information can indicate the LP-WUS types supported by a cell at a specific frequency. For details on this part, please refer to the relevant description of the embodiment shown in Figure 3.

[0237] Optionally, the second priority is used to perform cell reselection. This can be understood as using the second priority when determining the criteria for cell reselection. For example, for a UE, if all cells in the first frequency support LP-WUS or support the first type of LP-WUS, then all these cells can be treated equally during cell reselection. Alternatively, if at least one cell in the first frequency supports LP-WUS or supports the first type of LP-WUS, while the remaining cells do not support LP-WUS or do not support the first type of LP-WUS, then during cell reselection, the UE can prioritize reselecting to that at least one cell, or prioritize determining whether to reselect to that at least one cell. For example, for a UE, if multiple cells (corresponding to the same frequency or different frequencies) meet the cell reselection criteria, then the cell with the highest priority among those supporting LP-WUS or supporting the first type of LP-WUS, and ranked highest according to the R criterion, can be selected. This can also be understood as prioritizing the selection of cells supporting LP-WUS or supporting the first type of LP-WUS.

[0238] Optionally, the technical solutions of this application embodiment can be applied to measurement and / or cell reselection. For example, for a first frequency, the UE can use the first priority instead of the second priority during measurement (e.g., the UE does not adjust the priority during measurement), and can use the second priority instead of the first priority during cell reselection (e.g., the UE adjusts the priority during cell reselection); or, the UE can use the second priority instead of the first priority during both the measurement and cell reselection processes (e.g., the UE adjusts the priority during measurement). As another example, for a second frequency, the UE can use the fourth priority instead of the third priority during measurement, and use the third priority instead of the fourth priority during cell reselection. In this case, the UE still ensures that the high-priority frequency is measured, thereby ensuring the communication quality of the cell, and only adjusts the priority during cell reselection, so that the UE can avoid reselecting to cells with frequencies that do not support LP-WUS, and instead reselect to cells with frequencies that support LP-WUS, to achieve energy saving without affecting communication quality; or, the UE can use the third priority instead of the fourth priority during both the measurement and cell reselection processes.

[0239] Optionally, if there are frequencies that support LP-WUS, for example, if the M frequencies indicated by the second information include frequencies that support LP-WUS, then the UE can adopt the scheme of the present application embodiment; however, if there are no frequencies that support LP-WUS, for example, if none of the M frequencies support LP-WUS, then the UE can choose not to adopt the scheme of the present application embodiment, but instead perform measurement and cell reselection according to the original priority of the M frequencies (for example, the priority indicated by the first information).

[0240] Optionally, the UE in this application embodiment can be a UE with WUR capability. For a related introduction to the WUR capability, please refer to the embodiment shown in Figure 3.

[0241] For example, if a UE reselects to a first cell using the scheme in this embodiment, the UE can camp on the first cell. The first cell may support LP-WUS, or the LP-WUS type supported by the first cell may be the same as or overlap with the LP-WUS type supported by the UE. The first cell may or may not be the UE's original serving cell. If the first cell is not the UE's original serving cell, then the first cell and the UE's original serving cell may belong to the same network device or different network devices.

[0242] The UE can detect the LP-WUS in the first cell. For example, if the UE receives an LP-WUS from the first cell, it refers to this LP-WUS as the first LP-WUS. The first LP-WUS can be used to wake up the UE. For example, the first LP-WUS includes wake-up indication information, which can be used to wake up the UE. In this case, the UE can set the priority of the first frequency to the first priority, and / or set the priority of the second frequency to the fourth priority. For more details on this part, please refer to the relevant description of the embodiment shown in Figure 3.

[0243] In this embodiment, the UE can set the frequency priority according to whether it supports LP-WUS, so that the UE has a greater probability of selecting a cell with a frequency that supports LP-WUS when performing cell reselection. In this cell, the UE can receive LP-WUS, thereby achieving energy saving.

[0244] This application provides a third communication method, please refer to Figure 5, which is a flowchart of the method.

[0245] S501, UE determines the first frequency and the second frequency.

[0246] Optionally, the UE can determine the first frequency and the second frequency based on information from a network device (or the UE's serving cell). For example, the network device (or the UE's serving cell) sends second information. Accordingly, the UE receives the second information. The second information may indicate M frequencies, of which M1 frequencies support LP-WUS, and M2 frequencies do not support LP-WUS, M1 + M2 = M. Here, M is a positive integer, M1 can be an integer greater than or equal to 0, and M2 can also be an integer greater than or equal to 0. The M frequencies may include, for example, all or part of the frequencies to be tested by the UE. The M frequencies may be frequencies from neighboring cells, and may include one or more of the following: inter-frequency frequencies, co-frequency frequencies, or inter-system frequencies. Upon receiving the second information, the UE can determine which frequencies support LP-WUS. For example, the first frequency may belong to the M1 frequencies, and the second frequency may belong to the M2 frequencies and / or the M1 frequencies. The second information may be included, for example, in a broadcast message or a unicast message. Taking the inclusion of the second information in a broadcast message as an example, the second information may be included in system information, or it may also be included in other information.

[0247] The first frequency supporting LP-WUS can mean that the first frequency itself supports LP-WUS, or it can be understood as whether or not LP-WUS support is frequency-level; alternatively, the first frequency supporting LP-WUS can also mean that the cells under the first frequency support LP-WUS, or it can be understood as whether or not LP-WUS support is cell-level. The LP-WUS type supported by the first frequency can mean that the first frequency itself supports an LP-WUS type, or it can be understood as the LP-WUS type support being frequency-level; alternatively, the LP-WUS type supported by the first frequency can mean that the LP-WUS type support being cell-level. For more details on this, please refer to the relevant description of the embodiment shown in Figure 3.

[0248] Correspondingly, if LP-WUS support is frequency-level, optionally, the second information can indicate whether a certain frequency supports LP-WUS, for example, indicating that each of M1 frequencies supports LP-WUS. This can be understood as the second information indicating whether LP-WUS is supported at the frequency level, rather than indicating whether the cells at that frequency support LP-WUS. Alternatively, if LP-WUS support is cell-level, optionally, the second information indicates whether a certain frequency supports LP-WUS, specifically including whether the second information indicates whether each cell in some or all of the cells at that frequency supports LP-WUS. For details on this part, please refer to the relevant description of the embodiment shown in Figure 3.

[0249] The first frequency may include N frequencies, where N can be less than or equal to M1, and N is a positive integer. The second frequency may include K frequencies, where K can be less than or equal to M, and K is a positive integer.

[0250] S502, UE performs the first process on the first frequency.

[0251] S502 can also be understood as the UE prioritizing the first frequency for first processing. The term "priority" means that among the M frequencies, the UE prioritizes processing the first frequency, or prioritizes processing frequencies that support LP-WUS. The first frequency supports LP-WUS, for example, the UE considers the first frequency to support LP-WUS. For a related explanation, please refer to the embodiment shown in Figure 3.

[0252] Optionally, the second information may also indicate the type of LP-WUS supported by the first frequency, thereby allowing the UE to determine whether the first frequency supports LP-WUS. For example, the second information may indicate the type of LP-WUS supported by M1 frequencies, and the M1 frequencies include the N frequencies, thus effectively indicating the type of LP-WUS supported by the N frequencies. The first frequency includes N frequencies. For example, if all N frequencies support LP-WUS, the UE considers the N frequencies to support LP-WUS; or, if all N frequencies support LP-WUS, and the type of LP-WUS supported by the N frequencies is the same as or overlaps with the type of LP-WUS supported by the UE (e.g., the N frequencies support the first type of LP-WUS, and the UE also supports the first type of LP-WUS), then the UE considers the N frequencies to support LP-WUS.

[0253] If the second information indicates whether LP-WUS is supported at the frequency level, and the second information is to indicate the LP-WUS type, optionally, the second information can indicate the LP-WUS types supported at a specific frequency. This can be understood as the second information indicating the supported LP-WUS types at the frequency level, but not indicating the LP-WUS types supported by a specific cell at that frequency. Alternatively, if the second information indicates whether LP-WUS is supported at the cell level, and the second information is to indicate the LP-WUS type, optionally, the second information can indicate the LP-WUS types supported by a cell at a specific frequency. For details on this part, please refer to the relevant description of the embodiment shown in Figure 3.

[0254] If the serving cell needs to send the second information, it must first determine whether M1 of the M frequencies support LP-WUS and whether M2 frequencies do not. For example, the network device corresponding to the serving cell can communicate with the network devices corresponding to the M frequencies to obtain information on whether some or all of the M frequencies support LP-WUS, and also to obtain information such as the specific LP-WUS type supported by the frequencies that support LP-WUS. Thus, the serving cell can obtain the second information. For details on this part, please refer to the relevant description of the embodiment shown in Figure 3.

[0255] The first process includes, for example, measurement and / or cell reselection. Essentially, during measurement, the UE can prioritize measuring frequencies that support LP-WUS; and / or, during cell reselection, the UE can prioritize reselecting frequencies that support LP-WUS. Prioritizing measurement of LP-WUS-supporting frequencies during measurement ensures the UE obtains measurement results for these frequencies first, thus cells at these frequencies are prioritized as candidate cells for cell reselection. Similarly, prioritizing reselection of LP-WUS-supporting frequencies during cell reselection ensures that these cells are prioritized as candidate cells for cell reselection. This approach maximizes the UE's chances of reselecting cells at frequencies supporting LP-WUS.

[0256] Optionally, after executing S501, if the UE fails to determine the target cell based on the first frequency, the UE may perform the first processing again on the first frequency to try to reselect a cell under a frequency that supports LP-WUS. For example, if the UE fails to determine the target cell based on the first frequency, the UE may continue to perform the first processing on the first frequency for a first duration to try to reselect a cell under the first frequency. When the first duration expires, if the UE still fails to determine the target cell based on the first frequency, the UE may perform the second processing on the second frequency. The second processing may include measurement and / or cell reselection, wherein the second processing may be the same as or different from the first processing. In other words, if the UE cannot determine the target cell among cells under a frequency that supports LP-WUS, it can perform reselection among cells under a frequency that does not support LP-WUS to try to reselect a cell with better signal quality.

[0257] Alternatively, after executing S501, if the UE does not determine the target cell based on the first frequency, the UE may not need to perform the first processing on the first frequency again, but can perform the second processing on the second frequency to reselect a cell with better signal quality as soon as possible, thereby improving the efficiency of cell reselection.

[0258] Optionally, the UE in this application embodiment can be a UE with WUR capability. For a related introduction to the WUR capability, please refer to the embodiment shown in Figure 3.

[0259] For example, if a UE reselects to a first cell using the scheme in this embodiment, the UE can camp on the first cell. The first cell may support LP-WUS, or the LP-WUS type supported by the first cell may be the same as or overlap with the LP-WUS type supported by the UE. The first cell may or may not be the UE's original serving cell. If the first cell is not the UE's original serving cell, then the first cell and the UE's original serving cell may belong to the same network device or different network devices.

[0260] The UE can detect the LP-WUS in the first cell. For example, if the UE receives an LP-WUS from the first cell, this LP-WUS is referred to as the first LP-WUS. The first LP-WUS can be used to wake up the UE. For example, the first LP-WUS includes wake-up indication information, which can be used to wake up the UE. In this case, the UE can perform third processing on M frequencies. The third processing may include measurement and / or cell reselection. Optionally, if the UE determines that it has been woken up based on the first LP-WUS, it can perform third processing on the M frequencies. Alternatively, if the UE determines that it has been woken up based on the first LP-WUS, the UE can continue to detect paging messages in the first cell. After receiving a paging message, if it determines that the UE has been paged (e.g., the paging message includes the UE's identifier), the UE can perform third processing on the M frequencies; if it determines that the UE has not been paged (e.g., the paging message does not include the UE's identifier), the UE may not perform third processing on the M frequencies.

[0261] This can be understood as follows: if the UE is woken up by the first LP-WUS or is confirmed to be paged, it can perform cell reselection again (the reason for this can be referred to in the embodiment shown in Figure 3). After reselecting to a new cell, it can then enter the RRC connected state in that new cell. To reselect a cell that is beneficial for UE communication in the RRC connected state, the UE does not need to prioritize cells supporting LP-WUS. Instead, it can process both LP-WUS-supporting and non-LP-WUS-supporting cells uniformly. Alternatively, the UE can perform measurement and / or cell reselection in the traditional way, making it more likely to reselect to a cell with better communication quality. For example, if the UE performs measurement and / or cell reselection in the traditional way and enters a second cell, the UE can enter the RRC connected state in the second cell to communicate. Therefore, the technical solution of this application embodiment enables the UE to detect LP-WUS for energy saving and allows the UE to enter the RRC connected state in a cell with better communication quality, thereby improving the UE's communication quality.

[0262] In this embodiment, the UE can prioritize frequencies that support LP-WUS, thus increasing the probability that the UE can select a cell with a frequency supporting LP-WUS during cell reselection. Within this cell, the UE can receive LP-WUS signals, achieving energy savings. Furthermore, the UE does not need to reset frequency priorities, simplifying UE implementation.

[0263] This application provides a fourth communication method. Please refer to Figure 6, which is a flowchart of the method.

[0264] S601. The network device sends first information. Correspondingly, the UE receives the first information. For example, the network device sending the first information may include a specific cell provided by the network device sending the first information, where the cell is the serving cell of the UE, and the UE receives the first information in that serving cell.

[0265] The first information may indicate the first priority of a first frequency. For example, the first frequency may include M frequencies, where M is a positive integer. The M frequencies may be all or part of the frequencies to be measured by the UE, or they may be frequencies from neighboring cells, including one or more of the same-frequency, different-frequency, or different-system frequencies. The first priorities of different frequencies among the M frequencies may be the same or different. The first priority may correspond to or be associated with LP-WUS, or it may be understood that the first priority is a LP-WUS-specific priority. The first priority may correspond to or be associated with LP-WUS. For example, one way to correspond to or be associated with LP-WUS is that the first priority can be determined based on second information, which may include information on whether some or all of the M frequencies support LP-WUS. Optionally, the second information may also include other information, such as signal quality information corresponding to one or more of the M frequencies, without limitation.

[0266] In this embodiment, a frequency supporting LP-WUS means that the frequency's capability supports LP-WUS; a frequency not supporting LP-WUS means that the frequency's capability does not support LP-WUS. For a detailed explanation of whether a frequency's capability supports LP-WUS, please refer to the embodiment shown in Figure 3.

[0267] The embodiments of this application can be understood as follows: the network device can configure a new priority (i.e., the first priority) for the first frequency, and the UE can perform measurement and / or cell reselection according to the first priority in order to reselect to a cell under the frequency that supports LP-WUS as much as possible.

[0268] The first priority is associated with LP-WUS. For example, among M frequencies, the frequency that supports LP-WUS can have a higher first priority; while among M frequencies, the frequency that does not support LP-WUS can have a lower first priority. Optionally, among the M frequencies, the first priority of the frequency that supports LP-WUS can be higher than the first priority of the frequency that does not support LP-WUS. Specifically, if two frequencies both support LP-WUS, their first priorities can be the same or different; if two frequencies do not support LP-WUS, their first priorities can be the same or different.

[0269] Optionally, for frequencies supporting LP-WUS, there may be specific supported LP-WUS types. For an introduction to LP-WUS types, please refer to the embodiment shown in Figure 3. Different frequencies may support the same or overlapping LP-WUS types, or they may be different or non-overlapping. Optionally, a first priority corresponds to or is associated with an LP-WUS type. For example, for one or more or each LP-WUS type, a first priority for a first frequency is indicated. For instance, LP-WUS types include a first type of LP-WUS and a second type of LP-WUS. The first information may indicate the first priority corresponding to the first type of LP-WUS at the first frequency, and / or the first priority corresponding to the second type of LP-WUS at the first frequency. The first priority corresponding to the first type of LP-WUS and the first priority corresponding to the second type of LP-WUS may be the same or different.

[0270] Optionally, for frequencies supporting LP-WUS, there can be specific supported LP-WUS types. For an introduction to LP-WUS types, please refer to the embodiment shown in Figure 3. Different frequencies can support the same, overlapping, different, or non-overlapping LP-WUS types. Optionally, frequencies supporting more LP-WUS types can have a higher first priority; frequencies supporting fewer LP-WUS types can have a lower first priority. For example, if LP-WUS types are measured by WUR types, and frequency 1 supports WUR type 1 and WUR type 2, while frequency 2 supports WUR type 2 (i.e., frequency 1 supports two types of LP-WUS or two types of WUR, and frequency 2 supports one type of LP-WUS or one type of WUR), then the first priority of frequency 1 can be higher than the first priority of frequency 2. If two frequencies support the same number of LP-WUS types, their first priorities can be the same or different.

[0271] For example, N out of M frequencies support the LP-WUS type, where N is a positive integer less than or equal to M. Optionally, the second information may also indicate the LP-WUS types supported by the N frequencies. For example, the second information may indicate the LP-WUS type supported by each of the N frequencies, allowing the network device to determine the first priority of the N frequencies or the M frequencies. For instance, the network device may determine the first priority of the N frequencies or the M frequencies based on the number of LP-WUS types supported by each of the N frequencies.

[0272] How a network device determines the first priority of the M frequencies based on the second information depends on the implementation of the network device, and this application does not impose any restrictions on the embodiments thereof.

[0273] To determine the first priority of the M frequencies based on the second information, the network device must obtain the second information. For example, the network device can communicate with the network devices corresponding to the M frequencies to obtain information such as whether some or all of the M frequencies support LP-WUS, and the specific LP-WUS types supported by the frequencies that support LP-WUS. Optionally, if the LP-WUS support status of a frequency changes (e.g., from supporting LP-WUS to not supporting LP-WUS, or from not supporting LP-WUS to supporting LP-WUS, or the supported LP-WUS type changes), the network device corresponding to that frequency can send information to the network device that needs to determine the first priority to indicate the change. The network device can then determine or update the first priority of some or all of the M frequencies accordingly. Optionally, after configuring the first priority for the UE, if the first priority of any of the M frequencies is updated, the network device can reconfigure the updated first priority for the UE.

[0274] Optionally, the first information may also indicate the second priority of the M frequencies. The second priorities of different frequencies may be the same or different. The second priority may not correspond to or be associated with LP-WUS, or the second priority may be unrelated to LP-WUS. For example, one way to avoid this is that the second priority of the M frequencies can be determined based on third information, which does not include information on whether the M frequencies support LP-WUS. Optionally, the third information may also include other information, such as signal quality information corresponding to one or more of the M frequencies, without limitation. For example, the third information may include all or part of the information in the second information except for whether the M frequencies support LP-WUS. Alternatively, another way to avoid this is that the second priority of the M frequencies can be determined based on the remaining information in the second information, excluding whether the M frequencies support LP-WUS.

[0275] It can be understood that the network device in this application embodiment can configure two priorities for M frequencies, wherein the first priority is a new priority, or a priority determined by the network device based on new information (e.g., second information); and the second priority is the original priority, or a priority determined by the network device based on traditional information (e.g., third information).

[0276] As an optional application method for UE priority, for UEs with WUR capability (see the embodiment shown in Figure 3 for details on WUR capability), measurement and / or cell reselection can be performed according to the first priority to reselect to a cell with a frequency supporting LP-WUS as much as possible; for UEs without WUR capability (see the embodiment shown in Figure 3 for details on non-WUR capability), measurement and / or cell reselection can be performed according to the second priority. However, when performing measurement and / or cell reselection according to the second priority, cells supporting LP-WUS may not be measured or selected preferentially.

[0277] As an optional application method for UE priority, for UEs with WUR capability and supporting a certain LP-WUS type (see the embodiment shown in Figure 3 for an introduction to WUR capability), measurement and / or cell reselection can be performed according to the first priority. The first priority corresponds to or is associated with the LP-WUS type, thereby enabling the UE to reselect to a cell at a frequency supporting that LP-WUS type as much as possible. For UEs without WUR capability (see the embodiment shown in Figure 3 for an introduction to non-WUR capability), measurement and / or cell reselection can be performed according to the second priority. For UEs with WUR capability and supporting a certain LP-WUS type, if the first priority does not correspond to or is associated with that LP-WUS type, i.e., there is no first priority corresponding to that LP-WUS type, the UE can perform measurement and / or cell reselection according to the second priority. When performing measurement and / or cell reselection according to the second priority, cells supporting LP-WUS may not be measured or selected preferentially.

[0278] Optionally, the first priority corresponding to any one of the M frequencies can indicate the cell reselection priority (referred to as the first cell reselection priority) and / or the cell reselection sub-priority (referred to as the first cell reselection sub-priority) for that frequency; the second priority corresponding to any one of the M frequencies can indicate the cell reselection priority (referred to as the second cell reselection priority) and / or the cell reselection sub-priority (referred to as the second cell reselection sub-priority) for that frequency. The first cell reselection sub-priority can be an integer or a decimal; the second cell reselection sub-priority can be an integer or a decimal.

[0279] For example, the first information includes a first field and a second field, where the first field carries a first priority and the second field carries a second priority. The first field may include a first cell reselection priority parameter (e.g., cellReselectionPriority-LPWUS) and / or a first cell reselection sub-priority parameter (e.g., cellReselectionSubPriority-LPWUS), wherein the first cell reselection priority parameter indicates the first cell reselection priority, and the first cell reselection sub-priority parameter indicates the first cell reselection sub-priority; the second field may include a second cell reselection priority parameter (e.g., cellReselectionPriority) and / or a second cell reselection sub-priority parameter (e.g., cellReselectionSubPriority), wherein the second cell reselection priority parameter indicates the second cell reselection priority, and the second cell reselection sub-priority parameter indicates the second cell reselection sub-priority.

[0280] For the UE, if measurement and / or cell reselection is performed using the first priority, then the first absolute priority corresponding to the first priority can be used to perform the measurement and / or cell reselection. If measurement and / or cell reselection is performed using the second priority, then the second absolute priority corresponding to the second priority can be used to perform the measurement and / or cell reselection. The second absolute priority can be determined based on the second reselection priority. For example, if the second reselection priority indicates the second cell reselection priority but not the second cell reselection sub-priority, then the second absolute priority can be the second cell reselection priority. Alternatively, if the second reselection priority indicates both the second cell reselection priority and the second cell reselection sub-priority, then the second absolute priority can be determined based on both the second cell reselection priority and the second cell reselection sub-priority, such as the product, sum, or difference between the second cell reselection priority and the second cell reselection sub-priority. The first absolute priority can be determined based on the first priority, or it can be determined based on both the second and first priorities, as will be explained below.

[0281] For example, if the first priority indicates the reselection priority of the first cell but not the reselection sub-priority of the first cell, then the first absolute priority can be the reselection priority of the first cell, and the first absolute priority can be determined based on the first priority.

[0282] Alternatively, if the first priority indicates the first cell reselection priority and the first cell reselection sub-priority, then the first absolute priority can be determined based on the first cell reselection priority and the first cell reselection sub-priority, for example, as the product, sum, or difference of the first cell reselection priority and the first cell reselection sub-priority. In this case, the first absolute priority can be determined based on the first priority.

[0283] Alternatively, if the first priority indicates the first cell reselection sub-priority but not the first cell reselection priority, and the second priority indicates the second cell reselection priority (it may also indicate the second cell reselection sub-priority, or it may not indicate the second cell reselection sub-priority), then the first absolute priority can be determined based on the first cell reselection sub-priority and the second cell reselection priority, for example, as the product, sum, or difference of the first cell reselection sub-priority and the second cell reselection priority. In this case, the first absolute priority can be determined based on the second priority and the first priority.

[0284] Alternatively, if the first priority indicates the first cell reselection sub-priority but not the first cell reselection priority, and the second priority indicates the second cell reselection sub-priority and the second cell reselection priority, then the first absolute priority can be determined based on the first cell reselection sub-priority, the second cell reselection priority, and the second cell reselection sub-priority. For example, the second absolute priority can be determined based on the second cell reselection priority and the second cell reselection sub-priority, and then the first absolute priority can be determined based on the second absolute priority and the first cell reselection sub-priority. Optionally, the second absolute priority can be, for example, the product, sum, or difference of the second cell reselection priority and the second cell reselection sub-priority; the first absolute priority can be, for example, the product, sum, or difference of the first absolute priority and the first cell reselection sub-priority.

[0285] As an optional implementation of the first information, the first information may be included in system messages and / or dedicated signaling (e.g., RRC release messages). For example, the first information may be entirely included in system messages or dedicated signaling; or a portion of the first information may be included in system messages, and the remainder in dedicated signaling; or all of the first information may be included in either system messages or dedicated signaling. In this case, the network device may send the first information in both system messages and dedicated signaling, or it may send the first information only in one of these messages. If all of the first information may be included in either system messages or dedicated signaling, then if the network device sends the first information in both system messages and dedicated signaling, the UE can obtain the first information through both system messages and dedicated signaling. In this case, the UE can preferentially use the first information included in the dedicated signaling to improve the accuracy of the first information.

[0286] S602, UE determines the first priority or the second priority.

[0287] For example, if the UE has WUR capability, a first priority can be determined; or, if the UE does not have WUR capability, a second priority can be determined. In this case, the first priority corresponds to or is associated with LP-WUS.

[0288] Optionally, if the UE determines a first priority, the UE can use the first priority to perform measurements and / or cell reselection. Alternatively, the UE may not perform the "determine first priority" step; for example, if it is a UE with WUR capability, S802 can be replaced by the UE using the first priority to perform measurements and / or cell reselection.

[0289] Alternatively, if the UE determines a second priority, the UE can use the second priority to perform measurements and / or cell reselection. Alternatively, the UE may not perform the "determine second priority" step; for example, if the UE does not have WUR capability, S802 can be replaced by the UE using the second priority to perform measurements and / or cell reselection.

[0290] Optionally, the first priority corresponds to or is associated with the LP-WUS type. For example, the first priority corresponds to or is associated with the first LP-WUS type. If the UE has WUR capability and supports the first LP-WUS type, the first priority can be determined; or, if the UE does not have WUR capability, or the UE has WUR capability but does not support the first LP-WUS type, the second priority can be determined.

[0291] In this embodiment, for UEs with WUR capability, measurement and / or cell reselection can be performed using the first priority associated with LP-WUS, giving the UE a greater probability of selecting a cell with a frequency supporting LP-WUS. Within this cell, the UE can receive LP-WUS signals, thus achieving energy savings. For UEs without WUR capability, measurement and / or cell reselection can be performed using the second priority. Therefore, different priorities exist for measurement and / or cell reselection for UEs with different capabilities, ensuring that UEs with different capabilities can perform measurement and / or cell reselection.

[0292] This application provides a fifth communication method, please refer to Figure 7, which is a flowchart of the method.

[0293] S701, The network device sends the second information. Correspondingly, the UE receives the second information.

[0294] The second information may indicate the type of LP-WUS supported by the first frequency. The type of LP-WUS may be indicated, for example, by the type of WUR, and / or by the waveform corresponding to the LP-WUS (or WUR), as described in the embodiment shown in Figure 3.

[0295] The first frequency may include N frequencies, where N is a positive integer. For example, the second information indicates the type of LP-WUS supported by each of the N frequencies included in the first frequency, thus allowing the UE to determine whether the N frequencies support LP-WUS. For instance, the second information may indicate the type of LP-WUS supported by M1 frequencies, and these M1 frequencies include the first frequency; therefore, the second information indicates the type of LP-WUS supported by the first frequency. Here, M1 is a positive integer greater than or equal to N.

[0296] When a network device needs to send second information in the UE's serving cell, it first determines the LP-WUS types supported by the first frequency. Optionally, the network device can determine the LP-WUS types supported by M1 frequencies. For example, the network device corresponding to the serving cell can communicate with the network devices corresponding to the M1 frequencies to determine information such as the LP-WUS types supported by each of the M1 frequencies, thereby enabling the serving cell to obtain the second information. Optionally, for a frequency, if the support for LP-WUS changes (e.g., from supporting LP-WUS to not supporting LP-WUS, or from not supporting LP-WUS to supporting LP-WUS, or the supported LP-WUS types change), the network device corresponding to that frequency can send information to the network device corresponding to the serving cell to indicate the change, thereby enabling the serving cell to determine or update the LP-WUS types supported by the M1 frequencies. Optionally, after the network device sends the second information in the UE's serving cell, if the support for LP-WUS of any of the M1 frequencies is updated, the network device can reconfigure the updated information to the UE.

[0297] Optionally, the LP-WUS types supported by the first frequency may specifically include LP-WUS types supported by the first frequency itself. In this case, the LP-WUS types supported by cells under the first frequency are not considered, or it can be considered that the LP-WUS types supported by the first frequency are the LP-WUS types supported by every cell under the first frequency. This can be understood as the supported LP-WUS types being frequency-level or frequency-granular; that is, the supported LP-WUS type refers to the LP-WUS type supported by a specific frequency.

[0298] Alternatively, the LP-WUS types supported by the first frequency can specifically include the LP-WUS types supported by cells within the first frequency. In this case, it can be understood that the supported LP-WUS types are at the cell level or at the cell granularity; that is, the supported LP-WUS types refer to the LP-WUS types supported by a specific cell, rather than the LP-WUS types supported by the frequency.

[0299] If the second information indicates whether LP-WUS is supported at the frequency level, and the second information is to indicate the LP-WUS type, optionally, the second information can indicate the LP-WUS type supported at a specific frequency. This can be understood as the second information indicating the supported LP-WUS type at the frequency level, rather than indicating the LP-WUS type supported by a specific cell at that frequency.

[0300] Alternatively, if the second information indicates whether LP-WUS is supported at the cell level, and the second information is to indicate the LP-WUS type, optionally, the second information can indicate the LP-WUS type supported by a cell at a certain frequency. This can be understood as the second information indicating the supported LP-WUS type at the cell level, but not indicating the LP-WUS type supported by the frequency to which the cell belongs. For details on this part, please refer to the relevant description of the embodiment shown in Figure 3.

[0301] Optionally, the second information may also indicate M frequencies, of which M1 frequencies support LP-WUS, and M2 frequencies do not support LP-WUS, where M1 + M2 = M. Here, M is a positive integer, and M1 and M2 can both be positive integers. These M frequencies may include, for example, all or some of the frequencies to be tested by the UE. These M frequencies may include one or more of the following: inter-frequency frequencies, co-frequency frequencies, or inter-system frequencies. Upon receiving the second information, the UE can determine which frequencies support LP-WUS. A first frequency may belong to these M frequencies, for example, to M1 of the M frequencies.

[0302] Optionally, the first frequency supports LP-WUS, specifically including the first frequency itself supporting LP-WUS. In this case, it is not considered which cells under the first frequency support LP-WUS, or it can be assumed that all cells under the first frequency support LP-WUS. This can be understood as whether LP-WUS support is frequency-level or frequency-granular; that is, whether LP-WUS is supported refers to whether a specific frequency supports LP-WUS.

[0303] Alternatively, the first frequency may support LP-WUS, specifically including cells within the first frequency supporting LP-WUS. In this case, LP-WUS support can be understood as being at the cell level or at the cell granularity; that is, LP-WUS support refers to whether a specific cell supports LP-WUS, rather than whether the frequency supports LP-WUS. Furthermore, LP-WUS support within cells of the first frequency can include different implementation methods, which can be referred to the relevant descriptions in the embodiment shown in Figure 3.

[0304] If LP-WUS support is frequency-level, the second information can optionally indicate whether a specific frequency supports LP-WUS, for example, indicating that each of the M1 frequencies supports LP-WUS. This can be understood as the second information indicating LP-WUS support at the frequency level, rather than indicating whether the cell at that frequency supports LP-WUS.

[0305] Alternatively, if LP-WUS support is at the cell level, the second information may indicate whether a certain frequency supports LP-WUS. Specifically, the second information may indicate whether each cell in some or all cells at that frequency supports LP-WUS. It can be understood that the second information indicates whether LP-WUS is supported at the cell level, as described in the relevant description of the embodiment shown in Figure 3.

[0306] In this embodiment, the first frequency may be a frequency that the UE considers to support LP-WUS or to support LP-WUS functionality. For details regarding whether the UE considers a frequency to support LP-WUS or LP-WUS functionality, please refer to the relevant description of the embodiment shown in Figure 3.

[0307] Optionally, the first frequency may or may not include the frequency of the serving cell of the UE, as can be seen in the relevant description of the embodiment shown in Figure 3.

[0308] For details on how the second information is sent, please refer to the description of the embodiment shown in Figure 3.

[0309] Optionally, the method may also include S702, whereby the UE sets the priority of the first frequency to the second priority.

[0310] The second priority can be used to perform measurements and / or cell reselection. For example, the second priority can be used to perform measurements and / or cell reselection; or, the first priority can be used to perform measurements, and the second priority can be used to perform cell reselection. Here, measurement can be understood as performing RRM measurements on the frequency of the neighboring cell to be measured. This measurement can be used for cell reselection; for example, the measurement results obtained through this measurement can be used for cell reselection. The first priority can be the priority configured by the network device for the first frequency or the original priority of the first frequency, which will be discussed later.

[0311] Optionally, the second priority is used to perform cell reselection. This can be understood as using the second priority when determining the criteria for cell reselection. For example, for a UE, if all cells in the first frequency support LP-WUS or support the first type of LP-WUS, then all these cells can be treated equally during cell reselection. Alternatively, if at least one cell in the first frequency supports LP-WUS or supports the first type of LP-WUS, while the remaining cells do not support LP-WUS or do not support the first type of LP-WUS, then during cell reselection, the UE can prioritize reselecting to that at least one cell, or prioritize determining whether to reselect to that at least one cell. For example, for a UE, if multiple cells (corresponding to the same frequency or different frequencies) meet the cell reselection criteria, then the cell with the highest priority among those supporting LP-WUS or supporting the first type of LP-WUS, and ranked highest according to the R criterion, can be selected. This can also be understood as prioritizing the selection of cells supporting LP-WUS or supporting the first type of LP-WUS.

[0312] Optionally, the second priority can be higher than or equal to the first priority. This can be understood as the UE increasing the priority of frequencies supporting LP-WUS, so that during cell reselection, the UE is more likely to reselect cells on frequencies supporting LP-WUS, thus achieving energy savings. Optionally, the second priority can be the highest priority. For example, if there are eight frequency priorities, from priority 0 to priority 7, with priority 7 being the highest, then the second priority could be priority 7. Setting the priority of frequencies supporting LP-WUS to the highest priority increases the probability of the UE reselecting cells on those frequencies.

[0313] The first frequency includes N frequencies. For these N frequencies, the first priority of different frequencies can be the same or different, and the second priority of different frequencies can also be the same or different. For example, if the second priority of different frequencies among the N frequencies is the same, then the second priority can be the highest priority. Alternatively, if the second priorities of different frequencies among the N frequencies are different, then the second priority of a certain frequency among the N frequencies can be the highest priority, or it can be any priority that is higher than or equal to the first priority of that frequency.

[0314] Optionally, when setting a second priority for a first frequency, the UE may refer to the first priority. For example, the network device may send first information, which the UE receives; the first information may indicate the first priority of the first frequency. For a related description of the first information, please refer to the embodiment shown in Figure 3. Once the UE determines the first priority based on the first information, it can set the priority of the first frequency to a priority higher than or equal to the first priority; this priority is the second priority.

[0315] Alternatively, when setting a second priority for a first frequency, the UE may not refer to the first priority. For example, although the UE receives the first information, it does not determine the first priority based on it; it can be assumed that the UE is unaware of the first priority.

[0316] Alternatively, if the UE does not receive the first information (e.g., the UE fails to receive it, or the network device does not send the first information), the UE cannot know the first priority. In this case, the UE can directly set the priority of the first frequency to the highest priority (which is the second priority), which is relatively simple for the UE to implement.

[0317] Optionally, the method may also include S703, whereby the UE sets the priority of the second frequency to the third priority. For a detailed description of this step, please refer to the embodiment shown in Figure 3.

[0318] Optionally, the technical solutions of this application embodiment can be applied to measurement and / or cell reselection. For example, for a first frequency, the UE can use the first priority instead of the second priority during measurement (e.g., the UE does not adjust the priority during measurement), and can use the second priority instead of the first priority during cell reselection (e.g., the UE adjusts the priority during cell reselection). In this case, the UE does not need to measure more high-priority frequencies, thus not increasing the power consumption introduced by measurement, but only adjusting the priority during cell reselection, so that the UE can reselect to a cell under a frequency that supports LP-WUS as much as possible when performing cell reselection, so as to achieve better energy saving effect; or, the UE can use the second priority instead of the first priority in both the measurement process and the cell reselection process (e.g., the UE adjusts the priority during measurement). As another example, for a second frequency, the UE can use the fourth priority instead of the third priority during measurement, and use the third priority instead of the fourth priority during cell reselection; or, the UE can use the third priority instead of the fourth priority in both the measurement process and the cell reselection process.

[0319] Optionally, if there are frequencies that support LP-WUS, for example, if the M frequencies indicated by the second information include frequencies that support LP-WUS, or if the second information indicates the LP-WUS type supported by a certain frequency or cell, then the UE can adopt the scheme of the present application embodiment; however, if there are no frequencies that support LP-WUS, for example, if none of the M frequencies support LP-WUS, or if the second information does not indicate the LP-WUS type, then the UE can choose not to adopt the scheme of the present application embodiment, but instead perform measurement and cell reselection according to the original priority of the M frequencies (e.g., the priority indicated by the first information).

[0320] Optionally, the UE in this application embodiment can be a UE with WUR capability. For a related introduction to the WUR capability, please refer to the embodiment shown in Figure 3.

[0321] For example, if a UE reselects to a first cell using the scheme in this embodiment, the UE can camp on the first cell. The first cell may support LP-WUS, or the LP-WUS type supported by the first cell may be the same as or overlap with the LP-WUS type supported by the UE. The first cell may or may not be the UE's original serving cell. If the first cell is not the UE's original serving cell, then the first cell and the UE's original serving cell may belong to the same network device or different network devices.

[0322] The UE can detect the LP-WUS in the first cell. For example, if the UE receives an LP-WUS from the first cell, it refers to this LP-WUS as the first LP-WUS. The first LP-WUS can be used to wake up the UE. For example, the first LP-WUS includes wake-up indication information, which can be used to wake up the UE. In this case, the UE can set the priority of the first frequency to the first priority, and / or set the priority of the second frequency to the fourth priority. For more details on this part, please refer to the relevant description of the embodiment shown in Figure 3.

[0323] In this embodiment, the UE can set the frequency priority according to whether it supports LP-WUS, so that the UE has a greater probability of selecting a cell with a frequency that supports LP-WUS when performing cell reselection. In this cell, the UE can receive LP-WUS, thereby achieving energy saving.
