[0027] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. With respect to the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] The embodiments of the present application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced Long Term Evolution (LTE-A) system, New Radio (NR), NR system evolution system, LTE-based access to unlicensed spectrum (LTE-U) system, NR-based access to unlicensed spectrum (NR-U) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next generation communication system or other communication systems, etc.

[0029] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communications, but will also support, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), and vehicle-to-vehicle (V2V) communication, etc. The embodiments of the present application can also be applied to these communication systems.

[0030] Optionally, the communication system in the embodiment of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, or a standalone (SA) networking scenario.

[0031] The embodiments of the present application are not limited to the spectrum to which they are applied. For example, the embodiments of the present application can be applied to both licensed and unlicensed spectrum.

[0032] For example, the communication system 100 used in the embodiment of the present application is as follows: Figure 1 The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal or terminal). The network device 110 may provide communication coverage for a specific geographic area and may communicate with terminal devices within the coverage area.

[0033] Figure 1 One network device and two terminal devices are shown as an example. Optionally, the communication system 100 may include multiple network devices and each network device may include another number of terminal devices within its coverage area. This embodiment of the present application does not limit this.

[0034] Optionally, the communication system 100 may further include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

[0035] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be called a communication device. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above and will not be repeated here; the communication equipment may also include other devices in the communication system 100, such as a network controller, a mobile management entity and other network entities, which is not limited in the embodiments of the present application.

[0036] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0037] The embodiments of the present application are described in conjunction with terminal devices and network devices, wherein the terminal device may also be referred to as user equipment (UE), access terminal, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device, etc. The terminal device may be a station (STAION, ST) in a WLAN, a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, and a next-generation communication system, such as a terminal device in a NR network or a terminal device in a future evolved Public Land Mobile Network (PLMN) network.

[0038] As an example and not a limitation, in the embodiment of the present application, the terminal device may also be a wearable device. Wearable devices may also be called wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0039] A network device may be a device used to communicate with a mobile device. The network device may be an access point (AP) in WLAN, a base station (BTS) in GSM or CDMA, a base station (NodeB, NB) in WCDMA, an evolved base station (eNB or eNodeB) in LTE, or a relay station or access point, or a network device or base station (gNB) in a vehicle-mounted device, a wearable device, and an NR network, or a network device in a future evolved PLMN network, etc.

[0040] In an embodiment of the present application, a network device provides services for a cell, and a terminal device communicates with the network device through the transmission resources used by the cell (for example, frequency domain resources, or spectrum resources). The cell may be a cell corresponding to a network device (for example, a base station). The cell may belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, picocells, femtocells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0041] Before introducing the technical solution of this application, the following first introduces cell reselection and air interface slicing technology:

[0042] (1) Cell reselection

[0043] When a terminal device performs cell selection and reselection in a non-connected state (i.e., idle state or inactive state), a cell reselection strategy based on frequency priority (i.e., frequency point priority) is defined to meet load balancing in the idle state.

[0044] Cell reselection refers to the process by which a terminal, while disconnected, monitors the signal quality of neighboring cells and the current serving cell to select the best cell to provide service. If the signal quality and level of a neighboring cell meet the S criterion and certain reselection criteria, the terminal will connect to that cell and reside there.

[0045] After a terminal device successfully camps on a cell, it will continue to measure the cell. At the Radio Resource Control (RRC) layer, the terminal device calculates Srxlev (i.e., the S criterion) based on the Reference Signal Received Power (RSRP) measurement results and compares it with Sintrasearch (i.e., the same-frequency measurement start threshold) and Snonintrasearch (i.e., the inter-frequency / inter-system measurement start threshold) as the decision criteria for whether to start neighbor cell measurements.

[0046] When reselecting cells on the same frequency or different frequencies with the same frequency priority, the R criterion is used. This means that cells are ranked by signal quality and the cell with the best signal quality is selected as the candidate target cell. For cells with higher frequency priority, reselection is performed to cells with higher frequency priority as long as the cell signal quality meets a certain threshold. For cells with lower frequency priority, reselection is performed only when the serving cell's signal quality falls below a certain threshold.

[0047] (2) Air-interface slicing technology

[0048] Network slicing is deployed in 5G networks. Figure 2 This is the 5G network system architecture diagram, such as Figure 2 As shown, the 5G network system mainly includes UE, access network (Access Network, AN) equipment, access and mobility management function (Access and Mobility Management Function, AMF) entity, session management function (Session Management Function, SMF) entity, user plane function (User Plane Function, UPF) entity, policy control function (Policy Control function, PCF) entity, unified data management (Unified Data Management, UDM) entity, data network (Data Network, DN), application function (Application Function, AF) entity, authentication server function (Authentication Server Function, AUSF) entity, and network slice selection function (Network Slice Selection Function, NSSF) entity.

[0049] Specifically, in the 5G network system, the UE connects to the AN device through the Uu interface to exchange access layer messages and wireless data transmission, and the UE connects to the AMF entity through the N1 interface to communicate with the AMF entity in the non-access layer. The AN device is connected to the AMF entity through the N2 interface, and the AN device is connected to the UPF entity through the N3 interface; multiple UPF entities are connected through the N9 interface, the UPF entity is connected to the DN through the N6 interface, and at the same time, the UPF entity is connected to the SMF entity through the N4 interface; the SMF entity is connected to the PCF entity through the N7 interface, the SMF entity is connected to the UDM entity through the N10 interface, the SMF entity controls the UPF entity through the N4 interface, and at the same time, the SMF entity is connected to the AMF entity through the N11 interface; multiple AMF entities are connected through the N14 interface, the AMF entity is connected to the UDM entity through the N8 interface, the AMF entity is connected to the AUSF entity through the N12 interface, the AMF entity is connected to the NSSF entity through the N22 interface, and at the same time, the AMF entity is connected to the PCF entity through the N15 interface; the PCF entity is connected to the AF entity through the N5 interface; the AUSF entity is connected to the UDM entity through the N13 interface.

[0050] In the communications system, the UDM entity is the subscription database in the core network, storing user subscription data in the 5G network. The AMF entity is the mobility management function in the core network, and the SMF entity is the session management function in the core network. In addition to managing UE mobility, the AMF entity is also responsible for forwarding session management-related messages between the UE and the SMF entity. The PCF entity is the policy management function in the core network, responsible for formulating policies related to UE mobility management, session management, billing, and other aspects. The UPF entity is the user plane function in the core network, communicating with external data networks via the N6 interface and with AN equipment via the N3 interface. After the UE accesses the 5G network through the Uu port, a protocol data unit (PDU) session data connection is established from the UE to the UPF entity under the control of the SMF entity for data transmission. The AMF entity and the SMF entity obtain user subscription data from the UDM entity via the N8 and N10 interfaces, respectively, and obtain policy data from the PCF entity via the N15 and N7 interfaces.

[0051] In addition, there is a Network Exposure Function (NEF) entity in the 5G network system, which is used to interface with third-party application servers and transmit information between core network nodes and third-party applications.

[0052] It should be understood that a slice can be identified using a single network slice selection assistance information (S-NSSAI), and the collection of S-NSSAIs constitutes the network slice selection assistance information (NSSAI).

[0053] The following will be combined Figure 2 The following describes the process of obtaining slices:

[0054] When the UE needs to use a slice, it can send a registration request to the AMF. The registration request includes: an NSSAI request (Requested NSSAI). The NSSAI request can carry the S-NSSAI of the slice requested by the UE.

[0055] The AMF determines the allowed NSSAI based on the scope of the UE subscription and network slice deployment, carries the allowed NSSAI in the Registration accept, and sends it to the UE. It also carries the allowed NSSAI in the N2 interface message and sends it to the base station.

[0056] After receiving the allowed NSSAI, the UE needs to establish a Packet Data Unit (PDU) session in the slice corresponding to the S-NSSAI. Only after the PDU session is established can the UE send and receive data.

[0057] It should be understood that during network deployment, the coverage of each slice may be different. When determining the allowed NSSAI, the AMF needs to ensure that all slices identified by the allowed NSSAI can cover the registration area (Registration Area) assigned to the UE by the AMF, that is, the tracking area (TA) list. Among them, the AMF obtains the S-NSSAI and the corresponding TA supported by the base station from the base station through the NG setup request or RAN configuration update signaling, thereby determining the allowed NSSAI.

[0058] It should be understood that the NAS layer of the UE will provide the allowed NSSAI to the access layer. In version (Release, R) 17, the UE in the non-connected state reads the system information of the cell and can obtain the slice information supported by the base station and the frequency priority of each frequency when considering the slice. The UE can select a cell that supports the allowed NSSAI and supports UE services and has a high frequency priority based on the allowed NSSAI and the read system information to prepare for subsequent service transmission.

[0059] It should be understood that the UE selects a cell that can support the UE service and has a high frequency priority. Possible scenarios are as follows, but not limited to:

[0060] 1. The slices supported by different frequencies are the same or different. Figure 3 As shown in the right column of figures, the slices supported by frequency F1 and frequency F2 are both slice 1, indicating that the slices supported by different frequency points are the same. Figure 4 As shown in the left column of figures, the slice supported by frequency F1 is slice 1, and the slice supported by frequency F2 is slice 2, indicating that different frequencies support different slices.

[0061] 2. For the same slice, the frequency priorities of different frequencies are the same or different. Figure 4 As shown in the figure on the right, in the same slice 1, the frequency priority of frequency F1 is different from the frequency priority of frequency F2.

[0062] 3. The slices supported by the same frequency point are the same or different, that is, for the same frequency point, the slices supported by different cells are the same or different. Figure 3 As shown in the figure below, for the same frequency F1, the slices supported by cell 2 and cell 4 are both slice 1, which means that for the same frequency, different cells support the same slices. Figure 3 As shown in the upper row of figures, for the same frequency F2, the slices supported by cell 1 are slice 1 and slice 2, and the slice supported by cell 3 is slice 1, which means that for the same frequency, the slices supported by different cells are not exactly the same.

[0063] 4. For the same slice, the frequency priorities of the same frequency are the same or different, that is, for the same slice, the reselection priorities of different cells with the same frequency are the same or different. Assume that frequency priority 2 is higher than frequency priority 1, such as Figure 4 As shown in the upper row of figures, for the same slice 2, the frequency priority of frequency F2 in cell 5 and cell 7 is 1, indicating that the frequency priority of the same frequency in the same slice is the same. Figure 4 As shown in the lower row of figures, for the same slice 1, the frequency priority of frequency F1 in cell 6 is 2, and the frequency priority of frequency F1 in cell 7 is 1, indicating that the frequency priorities of the same frequency in the same slice are different.

[0064] For the above-mentioned fourth scenario, that is, for the same slice, the reselection priorities of different cells at the same frequency are the same or different. How to unify the frequency priority of the frequency is a technical problem that needs to be solved urgently in this application.

[0065] In order to solve this technical problem, the present application provides a first rule to determine the frequency priority of the frequency points.

[0066] The technical solution of this application will be described in detail below:

[0067] Figure 5 This is a flowchart of a wireless communication method provided in an embodiment of the present application, which can be executed by a terminal device, such as Figure 5 As shown, the method includes the following process:

[0068] S510: For the same slice and the same frequency, the terminal device determines a first frequency priority of the frequency according to a first rule. The first rule includes any one of the following, but is not limited to:

[0069] 1. Determine the priority of the first frequency point according to network instructions or predefined methods.

[0070] 2. Determine the first frequency priority based on the frequency priorities of different cells.

[0071] 3. Determine the first frequency priority based on the virtual frequency priorities of different cells according to the frequency.

[0072] 4. Determine the traditional frequency priority of the frequency as the first frequency priority.

[0073] S520 (optional): The terminal device reselects a cell according to the first frequency priority.

[0074] Optionally, the above-mentioned first frequency priority is also called the frequency priority based on the above-mentioned slice.

[0075] Optionally, the terminal device can obtain slice-related information from the network device, and the slice-related information includes at least one of the following: slices supported by the network device, and the frequency priority of the frequency point when considering the slice, for example: the frequency priority of the frequency point is the frequency priority of different cells at the same frequency point in the same slice.

[0076] Optionally, the above slices are one or more. If there are multiple slices, the multiple slices can be called a slice group.

[0077] Optionally, the above slice is at any of the following levels, but not limited to: cell, frequency, tracking area, and registration area.

[0078] Optionally, the above-mentioned slice can be identified by any of the following items, but not limited to: slice index (index), identifier, slice / service type (SST), cell group identifier, and parameters corresponding to the slice.

[0079] Optionally, the terminal device can determine the first frequency priority of the frequency according to the first rule for different cells of the same slice and the same frequency.

[0080] It should be understood that Article 2 and Article 3 of the above-mentioned first rule are for different cells in the same slice and the same frequency.

[0081] Optionally, the terminal device can determine the first frequency priority of the frequency in the same slice, the same frequency and the same cell according to Article 1 or Article 4 of the first rule.

[0082] Optionally, the terminal device can determine the first frequency priority according to the first rule for different cells with the same frequency point in the same slice, and when the frequency priorities of the frequencies based on different cells are different. Of course, when the frequency priorities of the frequencies based on different cells are the same, the terminal device can also determine the first frequency priority according to the first rule.

[0083] It should be understood that since the terminal device performs cell reselection based on the frequency priority of the frequency point, in this application, the frequency priority of the frequency point is also referred to as the cell reselection priority, which will not be repeated below.

[0084] It should be understood that when the frequency priorities of different cells based on the frequency point are different, determining the first frequency point priority according to the first rule is also described as, for the same slice and the same frequency point, different cells, if the reselection priorities of the different cells are different, determining the first frequency point priority or the reselection priority according to the first rule. Alternatively, it is described as, for the same slice, if there are different cells belonging to the same frequency point in the candidate cells, and the reselection priorities are different, determining the first frequency point priority or the reselection priority according to the first rule.

[0085] The following is an explanation of Article 1 of the first rule:

[0086] Optionally, for different cells with the same frequency in the same slice, the above network indication is used to indicate that one of the frequency priorities based on different cells is used as the first frequency priority, or to indicate that the traditional frequency priority of the frequency is used as the first frequency priority.

[0087] It should be understood that the traditional frequency priority means that the frequency priority is only related to the frequency and has nothing to do with the cell and slice.

[0088] Example 1: For the same slice 1 and the same frequency F1 in cell 1 and cell 2, the frequency priority of frequency F1 based on cell 1 is 1, and the frequency priority based on cell 2 is 3. Frequency priority 3 is higher than frequency priority 1. The network indicates that the frequency priority of frequency F1 based on cell 2 is used as the first frequency priority, that is, the final determined first frequency priority is 3.

[0089] Example 2: For the same slice 1 and the same frequency F1 in cell 1 and cell 2, the frequency priority of frequency F1 based on cell 1 is 1, and the frequency priority based on cell 2 is 3. Frequency priority 3 is higher than frequency priority 1. The network indicates that the traditional frequency priority of frequency F1 is used as the first frequency priority. Assuming that the traditional frequency priority of frequency F1 is 2, the final determined first frequency priority is 2.

[0090] Optionally, for different cells with the same frequency in the same slice, one of the frequency priorities based on the frequency priorities of different cells is used as the first frequency priority in a predefined manner, or the traditional frequency priority of the frequency is used as the first frequency priority in a predefined manner.

[0091] Example 3: For the same slice 1 and the same frequency F1 in cell 1 and cell 2, the frequency priority of frequency F1 based on cell 1 is 1, and the frequency priority based on cell 2 is 3. Frequency priority 3 is higher than frequency priority 1. According to the predefined method, the frequency priority of frequency F1 based on cell 2 is used as the first frequency priority, that is, the final determined first frequency priority is 3.

[0092] Example 4: For the same slice 1 and the same frequency F1 in cell 1 and cell 2, the frequency priority of frequency F1 based on cell 1 is 1, and the frequency priority based on cell 2 is 3. Frequency priority 3 is higher than frequency priority 1. According to a predefined method, the traditional frequency priority of frequency F1 is used as the first frequency priority. Assuming that the traditional frequency priority of frequency F1 is 2, the final determined first frequency priority is 2.

[0093] The following is a detailed explanation of Article 2 of the first rule:

[0094] Optionally, determining the first frequency priority based on frequency priorities of different cells according to the frequency includes any of the following, but is not limited to:

[0095] (1) The highest priority of the frequency points based on the frequency priorities of different cells is determined as the first frequency point priority.

[0096] (2) The lowest priority of the frequency points based on the frequency points priorities of different cells is determined as the first frequency point priority.

[0097] (3) The average priority of the frequency point based on the frequency priority points of different cells is determined as the first frequency point priority point.

[0098] (4) A priority randomly selected from the frequency priorities of different cells is determined as the first frequency priority.

[0099] (5) Determine the first frequency priority based on the frequency priorities of different cells according to the indexes and frequencies of different cells.

[0100] (6) Determine the first frequency priority based on the frequency priorities of different cells according to whether the cells are currently serving cells and the frequencies.

[0101] (7) Determine the first frequency priority based on the frequency priorities of different cells according to the channel quality and frequency of different cells.

[0102] (8) Determine the first frequency priority based on the frequency priorities of different cells according to the number of beams and frequencies of different cells.

[0103] (9) Determine the first frequency priority based on the frequency priorities of different cells according to the channel quality of different cells, the number of beams of different cells, and the frequency of different cells.

[0104] (10) Determine the first frequency priority based on the frequency priorities of different cells according to whether the different cells are cells other than the current serving cell and the frequency.

[0105] An example explanation of Article (1):

[0106] Example 5: For the same slice 1 and the same frequency F1 in cell 1 and cell 2, the frequency priority of frequency F1 based on cell 1 is 1, and the frequency priority based on cell 2 is 3. Frequency priority 3 is higher than frequency priority 1. The terminal device can determine frequency priority 3 as the first frequency priority.

[0107] An example explanation of Article (2):

[0108] Example 6: For the same slice 1 and the same frequency F1 in cell 1 and cell 2, the frequency priority of frequency F1 based on cell 1 is 1, and the frequency priority based on cell 2 is 3. Frequency priority 3 is higher than frequency priority 1. The terminal device can determine frequency priority 1 as the first frequency priority.

[0109] An example explanation of Article (3):

[0110] Example 7: For the same slice 1 and the same frequency F1 in cell 1 and cell 2, the frequency priority of frequency F1 based on cell 1 is 1, and the frequency priority based on cell 2 is 3. Frequency priority 3 is higher than frequency priority 1. The terminal device can determine the average value 2 of frequency priority 1 and frequency priority 3 as the first frequency priority.

[0111] An example explanation of Article (4):

[0112] Example 8: For the same slice 1 and the same frequency F1 in cell 1 and cell 2, the frequency priority of frequency F1 based on cell 1 is 1, and the frequency priority based on cell 2 is 3. Frequency priority 3 is higher than frequency priority 1. The terminal device can randomly select a frequency priority from frequency priority 1 and frequency priority 3. If frequency priority 3 is randomly selected, this frequency priority is determined as the first frequency priority.

Frequency priority 3 is higher than frequency priority 1. The index of cell 1 is 1, and the index of cell 2 is 2. The terminal device can select the cell with the smallest index of the two cells, that is, the frequency priority of cell 1 as the first frequency priority. That is, the terminal device finally determines frequency priority 1 as the first frequency priority.

[0117] Example 10: For the same slice 1 and the same frequency F1 in cell 1 and cell 2, the frequency priority of frequency F1 based on cell 1 is 1, and the frequency priority based on cell 2 is 3. Frequency priority 3 is higher than frequency priority 1. Assuming that the current serving cell is cell 1, the terminal device can use the frequency priority of cell 1 as the first frequency priority, that is, the terminal device finally determines frequency priority 1 as the first frequency priority.

Assuming that the current serving cell is cell 2, the terminal device can use the frequency priority of cell 2 as the first frequency priority, that is, the terminal device finally determines frequency priority 3 as the first frequency priority.

[0119] Explanation for Article (7):

[0120] In a first implementation method, the terminal device may select at least one second cell that meets the channel quality conditions based on the channel quality of different cells. The highest priority of the frequency points based on the frequency priorities of the at least one second cell is determined as the first frequency priority. Alternatively, the lowest priority of the frequency points based on the frequency priorities of the at least one second cell is determined as the first frequency priority. Alternatively, the average priority of the frequency points based on the frequency priorities of the at least one second cell is determined as the first frequency priority. Alternatively, a priority randomly selected from the frequency priorities of the at least one second cell is determined as the first frequency priority.

[0121] A second implementation method is that the terminal device selects the cell with the highest channel quality among different cells, and determines the frequency priority of the cell with the highest channel quality as the first frequency priority.

[0122] Optionally, the above-mentioned channel quality can be measured by at least one of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), received signal strength indication (RSSI), signal to interference plus noise ratio (SINR), and signal to noise ratio (SNR).

[0123] The following first describes an exemplary implementation method:

[0124] Example 12: For the same slice 1 and the same frequency F1 in cells 1, 2, and 3, the frequency priority of frequency F1 based on cell 1 is 1, the frequency priority based on cell 2 is 3, and the frequency priority based on cell 3 is 5. Frequency priority 5 is higher than frequency priority 3, which is higher than frequency priority 1. The channel quality of cell 1 is 20db, the channel quality of cell 2 is 10db, and the channel quality of cell 3 is 18db. The cell with the highest channel quality is cell 1. Assuming that the above channel quality condition falls within the channel quality interval [highest channel quality - 5, highest channel quality], that is, [15db, 20db], the cell 1 and cell 3 meet the channel quality condition. Here, the terminal device can use the highest priority of the frequency priorities of cells 1 and 3, that is, frequency priority 5, as the first frequency priority.

[0125] Example 13: For the same slice 1 and the same frequency F1 in cells 1, 2, and 3, the frequency priority of frequency F1 based on cell 1 is 1, the frequency priority based on cell 2 is 3, and the frequency priority based on cell 3 is 5. Frequency priority 5 is higher than frequency priority 3, which is higher than frequency priority 1. The channel quality of cell 1 is 20db, the channel quality of cell 2 is 10db, and the channel quality of cell 3 is 18db. The cell with the highest channel quality is cell 1. Assuming that the above channel quality condition falls within the channel quality interval [highest channel quality - 5, highest channel quality], that is, [15db, 20db], the cell 1 and cell 3 meet the channel quality condition. Here, the terminal device can use the lowest priority of the frequency priorities of cell 1 and cell 3, that is, frequency priority 1, as the first frequency priority.

[0126] Example 14: For the same slice 1 and the same frequency F1 in cells 1, 2, and 3, the frequency priority of frequency F1 based on cell 1 is 1, the frequency priority based on cell 2 is 3, and the frequency priority based on cell 3 is 5. Frequency priority 5 is higher than frequency priority 3, which is higher than frequency priority 1. The channel quality of cell 1 is 20db, the channel quality of cell 2 is 10db, and the channel quality of cell 3 is 18db. The cell with the highest channel quality is cell 1. Assuming that the above channel quality condition falls within the channel quality interval [highest channel quality - 5, highest channel quality], that is, [15db, 20db], the cell 1 and cell 3 meet the channel quality condition. Here, the terminal device can use the average of the frequency priorities of cells 1 and 3, that is, the frequency priority (1+5) / 2=3, as the first frequency priority.

[0127] Example 15: For the same slice 1 and the same frequency F1 in cells 1, 2, and 3, the frequency priority of frequency F1 based on cell 1 is 1, the frequency priority based on cell 2 is 3, and the frequency priority based on cell 3 is 5. Frequency priority 5 is higher than frequency priority 3, which is higher than frequency priority 1. The channel quality of cell 1 is 20dB, the channel quality of cell 2 is 10dB, and the channel quality of cell 3 is 18dB. The cell with the highest channel quality is cell 1. Assuming that the above channel quality condition falls within the channel quality interval [highest channel quality - 5, highest channel quality], that is, [15dB, 20dB], the cell 1 and cell 3 meet this channel quality condition. The terminal device randomly selects one of the frequency priorities of cell 1 and cell 3 as the first frequency priority.

[0128] The following first provides an exemplary description of the second possible implementation method:

[0129] Example 16: For the same slice 1 and the same frequency F1 in cells 1, 2, and 3, the frequency priority of frequency F1 based on cell 1 is 1, the frequency priority based on cell 2 is 3, and the frequency priority based on cell 3 is 5. Frequency priority 5 is higher than frequency priority 3, which is higher than frequency priority 1. The channel quality of cell 1 is 20dB, the channel quality of cell 2 is 10dB, and the channel quality of cell 3 is 18dB. The cell with the highest channel quality is cell 1. The terminal device can use the frequency priority of cell 1, i.e., frequency priority 1, as the first frequency priority.

[0130] Explanation of Article (8):

[0131] In a first implementation method, the terminal device selects at least one third cell that meets the beam quantity condition based on the number of beams of different cells. The highest priority of the frequency points based on the frequency priorities of the at least one third cell is determined as the first frequency priority. Alternatively, the lowest priority of the frequency points based on the frequency priorities of the at least one third cell is determined as the first frequency priority. Alternatively, the average priority of the frequency points based on the frequency priorities of the at least one third cell is determined as the first frequency priority. Alternatively, a priority randomly selected from the frequency priorities of the at least one third cell is determined as the first frequency priority.

[0132] A second implementation method is that the terminal device selects the cell with the largest number of beams among different cells, and determines the frequency priority of the cell with the largest number of beams as the first frequency priority.

[0133] The following first describes an exemplary implementation method:

[0134] Example 17: For the same slice 1 and the same frequency F1 in cells 1, 2, and 3, the frequency priority of frequency F1 based on cell 1 is 1, the frequency priority based on cell 2 is 3, and the frequency priority based on cell 3 is 5. Frequency priority 5 is higher than frequency priority 3, which is higher than frequency priority 1. The number of beams in cell 1 is 8, the number of beams in cell 2 is 12, and the number of beams in cell 3 is 16. The cell with the largest number of beams is cell 3. Assuming that the above beam number condition falls within the beam number interval [maximum number of beams - 5, maximum number of beams], that is, [11, 16], the cell 2 and cell 3 meet the channel quality condition here. Among them, the terminal device can use the highest priority of the frequency priorities of cells 2 and 3, that is, frequency priority 5, as the first frequency priority.

[0135] Example 18: For the same slice 1 and the same frequency F1 in cells 1, 2, and 3, the frequency priority of frequency F1 based on cell 1 is 1, the frequency priority based on cell 2 is 3, and the frequency priority based on cell 3 is 5. Frequency priority 5 is higher than frequency priority 3, which is higher than frequency priority 1. The number of beams in cell 1 is 8, the number of beams in cell 2 is 12, and the number of beams in cell 3 is 16. The cell with the largest number of beams is cell 3. Assuming that the above beam number condition falls within the beam number interval [maximum number of beams - 5, maximum number of beams], that is, [11, 16], the cell 2 and cell 3 meet the channel quality condition here. Among them, the terminal device can use the lowest priority of the frequency priorities of cells 2 and 3, that is, frequency priority 3, as the first frequency priority.

[0136] Example 19: For the same slice 1 and the same frequency F1 in cells 1, 2, and 3, the frequency priority of frequency F1 based on cell 1 is 1, the frequency priority based on cell 2 is 3, and the frequency priority based on cell 3 is 5. Frequency priority 5 is higher than frequency priority 3, which is higher than frequency priority 1. The number of beams in cell 1 is 8, the number of beams in cell 2 is 12, and the number of beams in cell 3 is 16. The cell with the largest number of beams is cell 3. Assuming that the above beam number condition falls within the beam number interval [maximum number of beams - 5, maximum number of beams], that is, [11, 16], the cell 2 and cell 3 meet the channel quality condition here. The terminal device can use the average of the frequency priorities of cells 2 and 3, that is, the frequency priority (3+5) / 2=4, as the first frequency priority.

[0137] Example 20: For the same slice 1 and the same frequency F1 in cells 1, 2, and 3, the frequency priority of frequency F1 based on cell 1 is 1, the frequency priority based on cell 2 is 3, and the frequency priority based on cell 3 is 5. Frequency priority 5 is higher than frequency priority 3, which is higher than frequency priority 1. The number of beams in cell 1 is 8, the number of beams in cell 2 is 12, and the number of beams in cell 3 is 16. The cell with the largest number of beams is cell 3. Assuming that the above beam number condition falls within the beam number interval [maximum number of beams - 5, maximum number of beams], that is, [11, 16], cells 2 and 3 meet the channel quality condition. The terminal device can randomly select one of the frequency priorities of cells 2 and 3 as the first frequency priority.

[0138] The following first provides an exemplary description of the second possible implementation method:

[0139] Example 21: For the same slice 1 and the same frequency F1 in cells 1, 2, and 3, the frequency priority of frequency F1 based on cell 1 is 1, the frequency priority based on cell 2 is 3, and the frequency priority based on cell 3 is 5.

For example, the eighth cell is the cell with the smallest cell index, or the cell with the highest frequency priority, or the cell with the largest index, or the cell with the lowest frequency priority, or any one of the cells.

[0161] The following is an example explanation of Article 3 of the first rule:

[0162] Example 31: For cell 1 and cell 2 in the same slice 1 and the same frequency F1, the frequency priority of frequency F1 based on cell 1 is 1, and the frequency priority based on cell 2 is 3, and the frequency priority 3 is higher than the frequency priority 1. The terminal device determines that the virtual frequency of cell 1 is A, and the corresponding virtual frequency priority is 3, and the virtual frequency of cell 2 is B, and the corresponding virtual frequency priority is 1. Based on this, the terminal device selects the highest virtual frequency priority 3 as the first frequency priority according to the virtual priorities of cell 1 and cell 2, or selects the lowest virtual frequency priority 1 as the first frequency priority, or randomly selects one from the virtual frequency priorities 1 and 3 as the first frequency priority, or takes the average value of the virtual frequency priorities 1 and 3, 2, as the first frequency priority.

[0163] Optionally, in Articles 1 and 4 of the first rule, assuming that the above-mentioned frequency point is referred to as the first frequency point, as described in Articles 1 and 4, the terminal device may determine the traditional frequency point priority of the first frequency point as the first frequency point priority. The terminal device may also determine the traditional frequency point priority as the frequency point priority of other frequency points other than the first frequency point, or, assuming that the method of determining the traditional frequency point priority as the frequency point priority other than the first frequency point in the first rule is called a slice-based frequency point priority determination method, then the terminal device may also use a slice-based frequency point priority determination method to determine the frequency point priority of other frequency points other than the first frequency point.

[0164] It should be understood that this embodiment is also applicable to frequencies or cells that do not support slicing, that is, for frequencies that do not support slicing, the terminal device can also determine the first frequency priority of the frequency according to the first rule. It can also be described as for cells that do not support slicing, the terminal device can determine the reselection priority of the cell according to the first rule.

[0165] In summary, in this application, for the same frequency in the same slice, the terminal device can determine the first frequency priority of the frequency according to the first rule. In particular, for different cells with the same frequency in the same slice, when the frequency priorities of the frequency based on different cells are different, the technical solution of this application can unify the frequency priority of the frequency.

[0166] Figure 6 This is a flowchart of another wireless communication method provided in an embodiment of the present application, which can be executed by a terminal device, such as Figure 6 As shown, the method includes the following process:

[0167] S610: For different cells with the same first frequency in different slices, the terminal device performs cell reselection according to a second rule. The second rule includes any one of the following:

[0168] 1. When performing cell reselection, exclude non-specific cells. Non-specific cells are cells that do not support the target slice.

[0169] 2. When performing cell reselection, the reselection priority of the non-specific cell is set to be different from the reselection priority of the specific cell. The specific cell is the cell that supports the target slice.

[0170] 3. Perform cell reselection according to the traditional frequency priority of the first frequency.

[0171] Optionally, the terminal device may obtain slice-related information from the network device, where the slice-related information includes at least one of the following: slices supported by the network device, and a frequency priority of a frequency point when considering the slice, for example, the frequency priority of the frequency point is a frequency priority for different cells of the same slice and the same frequency point. For another example, the frequency priority of the frequency point is a frequency priority for the same slice and the same frequency point.

[0172] Optionally, the above slices are one or more. If there are multiple slices, the multiple slices can be called a slice group.

[0173] Optionally, the above slice is at any of the following levels, but not limited to: cell, frequency, tracking area, and registration area.

[0174] Optionally, the above-mentioned slice can be identified by any of the following items, but not limited to: slice index, identifier, SST, cell group identifier, and parameters corresponding to the slice.

[0175] It should be understood that for different cells with the same first frequency in different slices, the terminal device reselects the cell according to the second rule. This is also described as if there are different cells with the same frequency in the candidate cells that support different slices, and the terminal device reselects the cell according to the second rule.

[0176] The following is an explanation of Article 1 of the second rule:

[0177] Optionally, the above-mentioned target slice is specified by the network device or determined by the terminal device itself, and this application does not impose any restrictions on this.

[0178] Optionally, the above target slice is the slice required by the terminal device.

[0179] Optionally, the step of excluding non-specific cells by the terminal device may be performed before cell reselection based on the frequency priority of the first frequency, or may be performed after cell reselection based on the frequency priority of the first frequency.

[0180] Optionally, the frequency priority of the first frequency here may be the frequency priority of the first frequency based on different cells, or the traditional frequency priority of the first frequency, and this application does not impose any restrictions on this.

[0181] Example 32: For cells 1 and 2 on the same frequency F1, cell 1 supports slice 1 and cell 2 supports slice 2. Slice 1 is the target slice. According to the above definitions of non-specific cells and specific cells, cell 1 is a specific cell and cell 2 is a non-specific cell. Assume that after performing inter-frequency cell reselection, if the corresponding cell 1 meets the channel quality conditions, the terminal device reselects to cell 1. If the corresponding cell 2 meets the channel quality conditions, the terminal device cannot reselect to cell 2.

[0182] The following is an explanation of Article 2 of the second rule:

[0183] It should be understood that the specific cell may be a candidate cell, a suitable cell, or an acceptable cell, and this application does not impose any limitation on this.

[0184] Optionally, when performing cell reselection, setting the reselection priority of a non-specific cell to be different from the reselection priority of a specific cell includes any of the following, but is not limited to:

[0185] (1) The reselection priority of the non-specific cell is set to be lower than the conventional frequency priority of all frequencies or lower than the frequency priority of the current serving cell.

[0186] (2) The reselection priority of the specific cell is set to be higher than the conventional frequency priority of the first frequency or the frequency priority of the first frequency based on the first slice, where the first slice is the slice corresponding to the specific cell.

[0187] (3) The reselection priority of the non-specific cell is set to be lower than the traditional frequency priority of all frequencies or lower than the frequency priority of the current serving cell, and the reselection priority of the specific cell is set to the traditional frequency priority of the first frequency or the frequency priority of the first frequency based on the first slice.

[0188] (4) The reselection priority of the non-specific cell is set to be lower than the traditional frequency priority of all frequencies or lower than the frequency priority of the current serving cell, and the reselection priority of the specific cell is set to be higher than the traditional frequency priority of the first frequency or the frequency priority of the first frequency based on the first slice.

[0189] (5) The reselection priority of the non-specific cell is set to the minimum value of the traditional frequency priority lower than the first frequency and the reselection priority of the current serving cell, and the reselection priority of the specific cell is set to the traditional priority of the first frequency or the frequency priority of the first frequency based on the first slice.

[0190] (6) The reselection priority of the non-specific cell is set to one of the conventional frequency priority lower than the first frequency and the reselection priority of the current serving cell, and the reselection priority of the specific cell is set to the conventional frequency priority of the first frequency or the frequency priority of the first frequency based on the first slice.

[0191] (7) The reselection priority of the non-specific cell is set to the minimum value of the traditional frequency priority lower than the first frequency and the frequency priority of the first frequency based on the first slice, and the reselection priority of the specific cell is set to the maximum value of the traditional frequency priority higher than or equal to the first frequency and the frequency priority of the first frequency based on the first slice.

[0192] (8) The reselection priority of the non-specific cell is set to the minimum value of the traditional frequency priority of the first frequency and the frequency priority of the first frequency based on the first slice, and the reselection priority of the specific cell is set to the maximum value of the traditional frequency priority of the first frequency and the frequency priority of the first frequency based on the first slice.

[0193] (9) The reselection priority of the non-specific cell is set to the minimum value between the traditional frequency priority of the first frequency and the frequency priority of the first frequency based on the second slice, and the reselection priority of the specific cell is set to the maximum value between the traditional frequency priority of the first frequency and the frequency priority of the first frequency based on the first slice, where the second slice is the slice corresponding to the non-specific cell.

[0194] It should be understood that the present application does not limit how to determine the frequency priority of the first frequency based on the first slice. For example, the terminal device can use the frequency priority of the first frequency based on the specific cell corresponding to the first slice as the frequency priority of the first frequency based on the first slice. Similarly, the present application does not limit how to determine the frequency priority of the first frequency based on the second slice. For example, the terminal device can use the frequency priority of the first frequency based on the non-specific cell corresponding to the second slice as the frequency priority of the first frequency based on the second slice.

[0195] Example 33: For cells 1 and 2 with the same frequency F1, cell 1 supports slice 1 and cell 2 supports slice 2. Slice 1 is the target slice. According to the above definitions of non-specific cells and specific cells, cell 1 is a specific cell and cell 2 is a non-specific cell. The terminal device determines that the virtual frequency of cell 2 is A, and its frequency priority is lower than the traditional priority of all frequencies, or lower than the frequency priority of the current serving cell. It determines that the reselection priority of cell 1 is the traditional priority of frequency F1 or the frequency priority of frequency F1 based on slice 1.

[0196] Example 34: For cells 1 and 2 with the same frequency F1, cell 1 supports slice 1 and cell 2 supports slice 2. Slice 1 is the target slice. According to the above definitions of non-specific cells and specific cells, cell 1 is a specific cell and cell 2 is a non-specific cell. The terminal device determines that the virtual frequency of cell 1 is A and the virtual frequency of cell 2 is B. The frequency priority of virtual frequency A is the frequency priority of frequency F1 based on slice 1. The frequency priority of virtual frequency B is the traditional frequency priority of frequency F1.

[0197] Example 35: For cells 1 and 2 with the same frequency F1, cell 1 supports slice 1 and cell 2 supports slice 2. Slice 1 is the target slice. According to the above definitions of non-specific cells and specific cells, cell 1 is a specific cell and cell 2 is a non-specific cell. The terminal device determines that the virtual frequency of cell 1 is A and the virtual frequency of cell 2 is B. The frequency priority of virtual frequency A is the highest priority of frequency F1 based on slice 1 and the traditional frequency priority of frequency F1. The frequency priority of virtual frequency B is the lowest priority of frequency F1 based on slice 2 and the traditional frequency priority of frequency F1.

[0198] The following is an explanation of Article 3 of the second rule:

[0199] Optionally, the terminal device may reselect a cell according to the traditional frequency priority of the first frequency. For frequency points other than the first frequency, the terminal device may also reselect a cell according to the traditional frequency priority of the other frequency points. Alternatively, assuming that the second rule refers to a method other than performing cell reselection according to the traditional frequency priority as a slice-based cell reselection method, the terminal device may also perform cell reselection in a slice-based cell reselection method for frequency points other than the first frequency.

[0200] Optionally, the other frequency points here may support the same slice as the first frequency point.

[0201] It should be understood that this embodiment is also applicable to frequencies or cells that do not support slicing, that is, for frequencies that do not support slicing, the terminal device can reselect the cell according to the second rule.

[0202] In summary, in this application, for different cells with the same first frequency in different slices, the terminal device performs cell reselection according to the second rule.

[0203] Optionally, if the system information block (SIB) message received by the terminal device carries the traditional frequency priority of the frequency, and a dedicated RRC message, such as an RRC release message, carries slice information (such as the slice index, identifier, etc.) and the frequency priority of the frequency based on the slice, the terminal device performs cell reselection according to the dedicated RRC message, such as the frequency priority and / or slice information carried in the RRC release message.

[0204] A possible way to write it is: In the case that the existing dedicated priority configuration is provided in SIB message while the slice info and per-slice frequency priority are provided in RRC Release message, UE follows the sliceinfo and per-slice frequency priority from RRC Release.

[0205] Optionally, if the SIB message received by the terminal device carries the traditional frequency priority of the frequency, and the RRC release message carries the information of the slice and the frequency priority of the frequency based on the slice, the terminal device reselects the cell according to the frequency priority and / or slice information carried in the RRC release message before the timer expires, and reselects the cell according to the traditional frequency priority of the frequency carried by the SIB message after the timer expires.

[0206] A possible way to write it is: In the case that the existing dedicated priority configuration is provided in SIB message while the slice info and per-slice frequency priority are provided in RRC Release message, UE follows the sliceinfo and per-slice frequency priority from RRC Release while T320-like timeris running.

[0207] Optionally, if the RRC release message does not carry the frequency priority of the frequency based on the slice, the terminal device determines that the frequency priority of the frequency supporting the slice is higher than the frequency priority of the frequency not supporting the slice, or the terminal device determines that the reselection priority of the cell supporting the slice is higher than the reselection priority of the cell not supporting the slice.

[0208] Optionally, if the SIB message received by the terminal device carries the first frequency priority of the frequency based on the slice, and the dedicated RRC message, such as the RRC release message, carries the second frequency priority of the frequency based on the slice, and the first frequency priority is different from the second frequency priority, the terminal device reselects the cell according to the dedicated RRC message, such as the second frequency priority carried in the RRC release message.

[0209] One possible way to write it is: In the case that both SIB and RRC Release providelice-specific frequency priorities whose values ​​are different for onespecific slice,UE follows slice-specific frequency priority from RRC Release.

[0210] Optionally, if the SIB message received by the terminal device carries the first frequency priority of the frequency based on the slice, and the RRC release message carries the second frequency priority of the frequency based on the slice, and the first frequency priority is different from the second frequency priority, the terminal device reselects the cell according to the second frequency priority carried in the RRC release message before the timer expires, and reselects the cell according to the first frequency priority carried by the SIB message after the timer expires.

[0211] One possible way to write it is: In the case that both SIB and RRC Release provideslice-specific frequency priorities whose values ​​are different for onespecific slice,UE follows slice-specific frequency priority from RRC Releasewhile T320-like timer is running.)

[0212] Optionally, if the SIB message received by the terminal device carries slice information and a frequency based on the first frequency priority of the slice, and a dedicated RRC message, such as an RRC release message, only carries slice information, the terminal device reselects the cell based on the slice information carried in the RRC release message and the first frequency priority carried in the SIB message.

[0213] One possible way to write it is: In the case that the slice info and per-slice frequency priority are provided in SIB message while only the slice info is provided in RRCRelease message,UE follows the slice info from RRCRelease and per-slice frequency priority from SIB.

[0214] Optionally, if the SIB message received by the terminal device carries slice information and a frequency based on the first frequency priority of the slice, and a dedicated RRC message, such as an RRC release message, only carries slice information, the terminal device reselects the cell based on the slice information carried in the RRC release message and the first frequency priority carried in the SIB message before the timer expires.

[0215] One possible way to write it is: In the case that the slice info and per-slice frequency priority are provided in SIB message while only the slice info is provided in RRCRelease message, UE follows the slice info from RRCRelease and per-slice frequency priority from SIB while T320-like timer is running.

[0216] Optionally, if the SIB message received by the terminal device carries slice information and a frequency based on the first frequency priority of the slice, and a dedicated RRC message, such as an RRC release message, only carries slice information, the terminal device determines that the frequency priority of the frequency supporting the slice is higher than the frequency priority of the frequency not supporting the slice, or the terminal device determines that the reselection priority of the cell supporting the slice is higher than the reselection priority of the cell not supporting the slice, or the terminal device reselects the cell according to the first frequency priority carried by the SIB message, or the terminal device reselects the cell according to the traditional frequency priority of the frequency.
