[0001] The embodiments of the present application relate to the field of mobile communication technology, and specifically to a wireless communication method and apparatus, terminal equipment, and base station. Background Art

[0002] In communications systems, the network maintains the continuity of terminal device communications services through a handover (HO) process, essentially handing off the terminal device's communication messages from the source base station to the target base station as smoothly as possible.

Furthermore, the network can send paging messages to idle or inactive terminal devices, notifying them to receive paging messages. How to flexibly enable terminal devices to perform cell handovers, access control, and paging monitoring has long been a concern.

[0051] FIG1 is a schematic diagram of an application scenario of an embodiment of the present application.

[0052] As shown in Figure 1, a communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0053] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto.

[0054] In the communication system 100 shown in Figure 1, the network device 120 may be an access network device that communicates with the terminal device 110.

[0064] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0065] 1. Radio Resource Control (RRC) status in NR

[0066] In order to reduce air interface signaling and quickly restore wireless connections and data services in the 5G network environment, a new RRC state is defined, namely the RRC inactive state (RRC_INACTIVE). This state is different from the RRC idle state (RRC_IDLE) and the RRC connected state (RRC_CONNECTED).

[0067] RRC_IDLE state: Mobility is based on cell selection and reselection of the terminal device. Paging is initiated by the core network and the paging area is configured by the core network. There is no terminal device access stratum (AS) context in the access network and no RRC connection exists.

[0068] RRC_CONNECTED state: The terminal device has an RRC connection with the access network, and an AS context exists between the terminal device and the access network. The core network knows the terminal device's location at the cell level. Unicast data can be transmitted between the terminal device and the access network.

[0069] RRC_INACTIVE: Mobility is based on cell reselection of the terminal device. The AS context of the terminal device exists on a certain base station. Paging is triggered by the access network (RAN). The RAN-based paging area is managed by the RAN. The network side knows the location of the terminal device based on the RAN paging area level.

[0070] 2. Conditional Handover (CHO) process

[0071] To address the issues of frequent handovers and handover failures in high-speed mobility and high-frequency deployment scenarios, the 3rd Generation Partnership Project (3GPP) introduced a condition-triggered handover process for LTE and NR systems in Release-16 (Rel-16).

[0072] Referring to Figure 2, the CHO process includes the following steps:

[0073] Step 1: Measurement configuration and reporting.

[0074] The source base station configures the terminal device to perform measurements, and the terminal device measures surrounding cells and submits a measurement package report.

[0075] Step 2: Prepare for CHO switching.

[0076] Wherein, if the source base station determines to use CHO, it sends a CHO request to a candidate target cell that meets the conditions according to the measurement report. If the candidate target cell agrees to the handover, a confirmation message is fed back to the source base station.

[0077] Step 3: The source base station sends a CHO command to the terminal device.

[0078] The CHO handover command may be configured with multiple candidate target cells, and a CHO execution condition may be configured for each candidate target cell.

[0079] It should be noted that the CHO execution conditions for each candidate target cell can include one or two triggering events. In Rel-16, the triggering events that can be used for CHO execution conditions can include A3 and A5 events. Rel-17 has agreed to allow A4 events to be used as triggering events in CHO execution conditions in non-terrestrial networks (NTN) systems. The terminal device determines which target cell to access based on the configured CHO execution conditions.

[0080] Currently, the measurement events supported in NR include the following:

[0081] A1 event: the signal quality of the serving cell is higher than a threshold;

[0082] A2 event: the signal quality of the serving cell is lower than a threshold;

[0083] Event A3: The signal quality of the neighboring cell exceeds a threshold compared to the signal quality of the special cell (SpCell), where the SpCell includes the primary cell (PCell) and the primary secondary cell (PSCell).

[0084] A4 event: the signal quality of the neighboring cell exceeds a threshold;

[0085] A5 event: The signal quality of the SpCell is lower than a threshold 1, and the signal quality of the neighboring cell is higher than a threshold 2;

[0086] A6 event: The signal quality of the neighboring cell is higher than the signal quality of the secondary cell (SCell) by a threshold;

[0087] Event B1: The signal quality of the neighboring cell with different technology exceeds a threshold;

[0088] Event B2: The signal quality of the PCell is lower than a threshold 1, and the signal quality of the neighboring cell with different technology is higher than a threshold 2.

[0089] Step 4: When the CHO conditions are met, access the target cell.

[0090] The terminal device can evaluate the switching execution conditions related to the candidate target cells. When the switching execution conditions of a candidate target cell are met, the terminal device executes the switching to the target cell (i.e., triggers the random access process and sends the switching completion message), avoiding the problem of not being able to send measurement reports and receive switching commands in time due to high-speed movement into a poor coverage area.

[0091] 3. Conditional PSCell Change (CPC)

[0092] To address the frequent PSCell changes in high-speed mobility and high-frequency deployment scenarios, 3GPP introduced a condition-triggered PSCell change process for LTE and NR systems in Rel-16. The basic principle is that the source base station pre-assigns the target cell to the terminal device, including the conditions for triggering the terminal device to perform the PSCell change.

[0093] The terminal device can evaluate the conditions configured according to the source base station. When the conditions are met, the terminal device initiates a PSCell change to avoid the problem of not being able to send measurement reports and receive PSCell change commands in time due to high-speed movement into a poor coverage area.

[0094] Similar to CHO, CPC allows the network to configure multiple candidate target cells for a terminal device and configure CPC execution conditions for each candidate target cell. Each CPC execution condition can include one or two triggering events. In Rel-16, the A3 and A5 events are available for CPC events. The terminal device can determine which target cell to access based on the configured CPC execution conditions.

[0095] 4. 5G NR Paging Mechanism

[0096] The main function of Paging is to enable the network to page the terminal device through a paging message when the terminal device is in the RRC_IDLE state or RRC_INACTIVE state, or to notify the terminal device of system message changes or earthquake tsunami / public warning information through a short message (applicable to all RRC states of the terminal device, including the connected state).

[0097] The paging channel may include a physical downlink control channel (PDCCH) scrambled by the radio network temporary identity (RNTI) and a physical downlink shared channel (PDSCH) scheduled by the PDCCH. Paging messages are transmitted in the PDSCH, and short messages are 8 bits in the PDCCH.

[0098] For terminal devices in RRC_IDLE or RRC_INACTIVE states, since there is no other data communication between the terminal device and the network, to save power, the terminal device can monitor the paging channel discontinuously, that is, using the Paging Discontinuous Reception (DRX) mechanism. Under the Paging DRX mechanism, the terminal device only needs to monitor the paging channel during one paging occasion (PO) within each DRX cycle. A PO is a series of PDCCH monitoring occasions and can be composed of multiple time slots.

[0099] Optionally, the terminal device may first calculate the system frame number SFN of the paging frame (PF) according to formula (1). The PF may include multiple POs or the starting positions of multiple POs.

[0100] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N) (1)

[0101] Where PF_offse is the PF offset parameter, T is the DRX cycle, and N is the total number of PFs in a DRX cycle. UE_ID can be determined based on the temporary mobile subscriber identifier (TMSI) of the terminal equipment (UE). For example, UE_ID can be 5G-S-TMSI mod 1024.

[0102] Furthermore, the terminal device may determine the index value i_s of the PO in the PF according to formula (2).

[0103] i_s=floor(UE_ID / N)mod Ns (2)

[0104] Where Ns is the number of POs included in a PF.

[0105] The terminal device can determine the position of the PF and the index value of the PO in each paging DRX cycle according to the above formula (1) and formula (2). It should be understood that the PO can be composed of multiple PDCCH monitoring occasions. A PO can contain X PDCCH monitoring occasions, where X is equal to the number of synchronization signal blocks (SSBs) actually sent as broadcast in the MIB.

[0106] After determining the PF, the index value of the PO, and the number of PDCCH monitoring occasions in the PO, the terminal device only needs to know the starting position of the first PDCCH monitoring occasion in the PO through relevant configuration parameters. This actual position can be configured through higher-layer signaling or obtained based on the PO index. The terminal device can blindly detect paging messages based on the determined PO.

[0107] With the growth in the number of communications devices and increasing user demand for diverse, high-quality services, energy consumption has become a significant component of operators' operating costs. Currently, energy costs for communications networks account for approximately 23% of operators' total costs. The majority of this energy consumption comes from wireless access networks, particularly active antenna units (AAUs), while data centers and fiber optic transmission contribute only a smaller share.

[0108] There are two types of power consumption in communication networks:

[0109] Dynamic part: includes power consumption during data transmission / reception;

[0110] Static portion: includes the consumption necessary to maintain the operation of the wireless access device even when there is no continuous data transmission / reception.

[0111] Current energy-saving technologies typically target terminal devices and do not consider network energy conservation. Furthermore, the specific details and impacts of network energy conservation technologies have yet to be studied and discussed. Therefore, the present embodiment discusses network energy conservation from the perspectives of cell handover, access control, and paging monitoring.

[0112] It should be noted that the methods or embodiments mentioned in this application document can be implemented separately, some of the methods or some of the embodiments can be implemented in combination, and all of the methods or embodiments can be implemented in combination, and this application does not impose any restrictions on this.

[0113] Example 1

[0114] This embodiment introduces the relevant process of cell switching in detail.

[0115] An embodiment of the present application provides a wireless communication method. Referring to FIG3 , the wireless communication method may include the following steps:

[0116] Step 110: The source base station or source cell sends handover configuration information;

[0117] Step 120: The terminal device receives handover configuration information, where the handover configuration information includes a handover configuration and / or conditions that the terminal device needs to meet for performing cell handover.

[0118] Optionally, the above-mentioned terminal device can be a terminal device that establishes a connection or has data transmission under the source base station or source cell.

[0119] Optionally, the source base station or source cell sends switching configuration information to the terminal device.

[0120] Optionally, the terminal device may receive handover configuration information from a source base station or a source cell.

[0121] Optionally, the source base station or source cell may also send switching configuration information to other terminal devices, so that other terminal devices can forward the switching configuration information to the terminal device. This embodiment of the present application does not impose any restrictions on this.

[0122] Optionally, the source base station or source cell may send the above-mentioned handover configuration information to the terminal device through group signaling or a dedicated message. Exemplarily, the group signaling may include group downlink control information (DCI), a control element (CE) message of the group media access control layer (MAC), or a group RRC message, or multicast information, etc., which is not limited in the embodiment of the present application. The dedicated message may include RRC dedicated signaling, that is, the above-mentioned handover configuration information can be configured through RRC dedicated signaling.

[0123] In some embodiments, the terminal device may perform handover according to handover configuration information, wherein the handover configuration information includes a handover configuration and / or conditions that the terminal device needs to meet to perform cell handover.

[0124] Optionally, the handover configuration in the above-mentioned handover configuration information may be a handover configuration of one or more candidate target cells. The handover configuration information may include relevant configuration information of one or more candidate target cells. Exemplarily, the handover configuration information may include physical cell identifier (PCI) information of one or more candidate target cells, the frequency corresponding to the candidate target cell, the cell RNTI allocated by the candidate target cell to the terminal device, the random access channel (RACH) resource information required for accessing the candidate cell (the random access channel RACH resource information required for accessing the candidate cell may include dedicated RACH resource information and / or public RACH resource information, etc.), the index value of the candidate target cell, etc. Of course, in other embodiments, the configuration information of the candidate target cell may also include other information not mentioned, and the embodiments of the present application are not limited to this.

[0125] It should be noted that the configuration information of the one or more candidate target cells may be generated by each candidate target cell. Each candidate target cell may exchange its own configuration information with the source base station or source cell, so that the source base station or source cell may carry the configuration information of each candidate target cell in the handover configuration information.

[0126] In addition, the conditions in the above-mentioned handover configuration information may be generated by the source base station or source cell and sent to the terminal device.

[0127] It can be seen that in the embodiments of the present application, the source base station or source cell can configure the handover configuration for the terminal device, as well as the conditions that the terminal device must meet when performing a cell handover. In this way, the terminal device can switch based on the conditions before performing a cell handover, thereby improving the flexibility of the terminal device in performing cell handover.

[0128] In some embodiments, the conditions required for the terminal device to perform cell switching included in the switching configuration information may be related to one or more of network status, network capability, network type, and network energy saving (NES) information.

[0129] Optionally, the network state may include a network on state, a network energy-saving state, an NES state, etc. It should be noted that when the network is in the off state, the energy-saving state, or the NES state, the network may stop providing all services to the terminal device, or the network may stop providing unnecessary services to the terminal device and only provide some necessary services.

[0130] Optionally, the network capability may include the capability to support energy saving, the capability to support NES, etc. It should be noted that for a network that supports energy saving or NES capabilities, it may stop providing services to the terminal device or stop providing some unnecessary services to the terminal device when in the energy saving state or NES state.

[0131] Optionally, the network type may include a protocol version type of the network, an access type of the network, etc. It should be noted that networks of different network types may provide different services for terminal devices.

[0132] Optionally, the NES information may include time information when the network is in the NES state, or time information when the network uses the NES function, etc., which is not limited in the embodiment of the present application.

[0133] In some embodiments, the above conditions may include conditions related to the network status, network capabilities, network type, and NES information of the source base station or source cell; and / or conditions related to the network status, network capabilities, network type, and NES information of the target base station or target cell.

The first protocol version may be a protocol version that supports network energy saving or NES technology. For example, the first protocol version may be Rel-18 or a subsequent version of Rel-18.

The above-mentioned channel conditions may be pre-configured, network-configured, or protocol-specified, which are not limited in this embodiment of the present application.

[0261] It should also be noted that the second indication information may be sent by the source base station or source cell. The source base station or source cell may send the second indication information via group signaling or via a dedicated message, which is not limited in the present embodiment.

[0262] In some embodiments, the second indication information may be determined based on state indication information of the target base station or target cell; the state indication information is used to indicate any one of a non-NES state, an ON state, a DTX ON state, a DTX OFF state, a DRX ON state, and a DRX OFF state of the target base station or target cell;

The second indication information may be explicit indication information, that is, the second indication information may directly instruct the terminal device to perform switching evaluation; or directly instruct the terminal device to perform or trigger switching using switching configuration information; directly instruct the terminal device to perform switching based on the pre-configured target cell configuration information; or directly indicate conditions related to network status, network capabilities, network type, and NES information. The embodiment of the present application does not limit the indication method of the second indication information.

[0269] Optionally, the second indication information may multiplex the status indication information of the target base station or target cell, wherein the status indication information of the target base station or target cell may be sent by the source base station or source cell. Exemplarily, if the source base station or source cell indicates to the terminal device that the target base station or target cell enters any one of the non-NES state, ON state, DTX ON state, DTX OFF state, DRX ON state, and DRX OFF state, the terminal device may consider that the source base station or source cell has sent the second indication information.

[0273] Optionally, the second indication information may be displayed indication information. When the target base station or target cell requires the terminal device to perform cell switching, the source base station or source cell may be triggered to send the second indication information to the terminal device, instructing the terminal device to perform cell switching. Exemplarily, the second indication information may be 1-bit information. When the second indication information takes a value of 0 / 1, the terminal device is instructed to perform cell switching.

[0274] In some embodiments, the above conditions are for all cells. That is, the above conditions can be common conditions.

[0275] Exemplarily, for different terminal devices, the above-mentioned conditions related to the network status, network capabilities, network type, and NES information of the source base station or source cell are the same; for different source cells in any of the OFF state, NES state, DTX ON state, DTX OFF state, DRX ON state, and DRX OFF state, the above-mentioned conditions related to the network status, network capabilities, network type, and NES information of the source base station or source cell are the same.

[0276] Optionally, the above conditions may also be cell-specific.

[0277] Exemplarily, for different target cells, the above-mentioned conditions related to the network status, network capability, network type, and NES information of the target base station or target cell are different. Alternatively, for different target cells in any of the OFF state, NES state, DTX ON state, and DTX OFF state, the above-mentioned conditions related to the network status, network capability, network type, and NES information of the target base station or target cell are different. For different candidate target cells, the available time, or the triggerable switching time, or the time when switching to the target cell can be selected, or the time when connection and / or transmission with the terminal device can be different; for the source cell and the candidate target cells, the available time, or the triggerable switching time, or the time when switching to the target cell can be selected, or the time when connection and / or transmission with the terminal device can be different.

[0278] In summary, the source base station or source cell can configure conditions for cell handover for terminal devices. These conditions may be related to network status, network capabilities, network type, and NES information. This allows terminal devices to perform cell handover based on the current network status, network capabilities, network type, and NES information, avoiding continuous access to a source base station or source cell where data transmission is not possible, and avoiding handover to a target base station or target cell where data transmission is not possible. This ensures normal data transmission while achieving network energy conservation.

[0279] In some embodiments, the switching configuration information may further include one or more of the following:

[0280] an execution condition / evaluation condition for each of the one or more candidate target cells;

[0281] Execution conditions / evaluation conditions of all candidate target cells in one or more candidate target cells.

[0282] It is understandable that the terminal device can determine which target cell to access based on the configured execution conditions / evaluation conditions, that is, when the execution conditions / evaluation conditions of a candidate target cell are met, the terminal device can actively switch to the candidate target cell.

[0283] That is, the handover configuration information provided in the embodiment of the present application may be CHO-like configuration information. Accordingly, the cell handover in the embodiment of the present application may also refer to CHO-like handover.

[0284] It should be noted that the execution conditions / evaluation conditions of the one or more candidate target cells configured in the handover configuration information may be the same or different. The source base station or source cell may configure separate execution conditions / evaluation conditions for each of the one or more candidate target cells, or uniformly configure one execution condition / evaluation condition for the one or more candidate target cells.

[0285] The following describes in detail the process of the terminal device performing cell switching based on the switching configuration information.

[0286] In some embodiments, the wireless communication method provided in the embodiments of the present application may further include the following steps:

[0287] When one or more of the following conditions are met, the terminal device performs cell handover, or considers that the cell handover execution condition is met, or triggers handover evaluation, or the terminal device leaves the source base station or source cell:

[0288] A first condition, the first condition is related to a source base station or a source cell;

[0289] A second condition, the second condition is related to the target base station or target cell;

[0290] The third condition is related to the terminal device;

[0291] The fourth condition is related to the information received by the terminal device.

[0292] In some embodiments, the first condition may include one or more of the following:

[0293] Conditions related to the network status, network capabilities, network type, and NES information of the source base station or source cell;

[0294] The duration for which the source base station or source cell is in any of the following states: NES state, OFF state, DTX ON state, DTX OFF state, DRX ON state, or DRX OFF state is greater than the first duration;

[0295] The duration for which the source base station or source cell uses any of the following functions: NES, OFF, DTX ON, DTX OFF, DRX ON, or DRX OFF is greater than the first duration;

[0296] The first channel quality is less than or equal to the first threshold; the first channel quality is the channel quality between the terminal device and the source base station or the source cell;

[0297] The difference between the second channel quality and the first channel quality is greater than a second threshold; the second channel quality is the channel quality between the terminal device and the target base station or target cell.

[0298] It should be understood that the first condition may include the conditions related to the network status, network capability, network type, and NES information of the source base station or source cell contained in the above-mentioned handover configuration information.

[0299] It should be noted that, in the embodiment of the present application, the network status, network capability, network type, and NES information of the source base station or source cell can be indicated in the above-mentioned handover configuration information, or can be separately indicated by other information other than the handover configuration information. The embodiment of the present application does not limit this. For example, the source base station or source cell is in the on state / off state, the time information of the on state / off state, the NES state / non-NES state, and the time information of the NES state / non-NES state can be indicated by the above-mentioned handover configuration information, or by RRC dedicated / group signaling, MAC CE dedicated / group signaling, and DCI dedicated / group signaling.

[0300] Optionally, the first duration can be predefined, or independently configured, or configured through the above-mentioned switching configuration information, or configured to the terminal device by the source base station or source cell when the source base station or source cell switches from other states to any of the NES state, OFF state, DTX ON state, DTX OFF state, DRX ON state, and DRX OFF state. The embodiments of the present application do not impose any restrictions on this.

[0301] In the embodiment of the present application, the terminal device may further detect whether the source base station or source cell is performing implicit energy saving. When the terminal device detects whether the source base station or source cell is performing implicit energy saving, a cell handover may also be triggered.

[0302] Optionally, the terminal device may measure the first channel quality between it and the source base station or source cell. If the first channel quality is less than or equal to a first threshold, the terminal device may consider that the source base station or source cell is implicitly energy-saving.

[0303] Optionally, the terminal device may also measure the second channel quality between it and the target base station or target cell. If the difference between the second channel quality and the first channel quality is greater than or equal to a second threshold, it may be considered that the source base station or source cell is implicitly saving energy, or that the channel quality between the terminal device and the target base station or target cell is good, while the channel quality between the terminal device and the source base station or source cell is relatively poor. When the terminal device detects that the difference between the second channel quality and the first channel quality is greater than or equal to the second threshold, a cell handover may also be triggered to switch to a target cell with better channel quality.

[0304] It should be noted that the first threshold and / or the second threshold may be a predefined value or a value indicated in the CHO execution condition, and this embodiment of the present application does not limit this.

[0305] In some embodiments, the second condition may include one or more of the following:

[0306] Conditions related to the network status, network capabilities, network type, and NES information of the target base station or target cell;

[0307] The second channel quality is greater than or equal to a third threshold;

[0308] The difference between the second channel quality and the first channel quality is greater than or equal to a second threshold;

[0309] The target base station or target cell meets the CHO execution conditions / CHO evaluation conditions;

[0310] The target base station or target cell meets the CHO execution conditions / CHO evaluation conditions, and the target base station or target cell does not use any of the functions NES, OFF, DTX ON, DTX OFF, DRX ON, or DRX OFF;

[0311] The target base station or target cell meets the CHO execution condition / CHO evaluation condition, and the target base station or target cell is in any of the following states: non-NES state, ON state, DTX ON state, DTX OFF state, DRX ON state, and DRX OFF state;

[0312] The target base station or target cell meets the CHO execution conditions / CHO evaluation conditions, and the target base station or target cell does not support any of the functions NES, OFF, DTX ON, DTX OFF, DRX ON, and DRX OFF;

[0313] The target base station or target cell does not use any of the following functions: NES, OFF, DTX ON, DTX OFF, DRX ON, or DRX OFF;

[0314] The target base station or target cell is in any of the following states: non-NES state, ON state, DTX ON state, DTX OFF state, DRX ON state, and DRX OFF state;

[0315] The target base station or target cell does not support any of the following functions: NES, OFF, DTX ON, DTX OFF, DRX ON, or DRX OFF.

[0316] It should be understood that the first condition may include the conditions related to the network status, network capability, network type, and NES information of the target base station or target cell contained in the above-mentioned handover configuration information.

[0317] It should be noted that the network status, network capability, network type, and NES information of the above-mentioned target base station or target cell can be indicated in the above-mentioned handover configuration information, or can be separately indicated by other information other than the handover configuration information. The embodiment of the present application does not limit this. The embodiment of the present application does not limit this. For example, the source base station or source cell is in the NES state / non-NES state, and the energy-saving time information can be indicated by the handover configuration information, or by RRC dedicated / group signaling, MAC CE dedicated / group signaling, or DCI dedicated / group signaling.

[0318] Optionally, the terminal device can measure the second channel quality between it and the target base station or target cell. If the second channel quality is greater than a third threshold, the terminal device can consider that the target base station or target cell can provide better service to the terminal device. At this time, the terminal device can access the target base station or target cell.

[0319] Optionally, the terminal device may also measure the second channel quality between it and the target base station or target cell. If the difference between the second channel quality and the first channel quality is greater than or equal to a second threshold, it may be considered that the source base station or source cell is implicitly saving energy, or that the channel quality between the terminal device and the target base station or target cell is good, while the channel quality between the terminal device and the source base station or source cell is relatively poor. When the terminal device detects that the difference between the second channel quality and the first channel quality is greater than the second threshold, a cell handover may also be triggered to switch to a target cell with better channel quality.

[0320] It should be noted that the third threshold may be a predefined value or a value indicated in the CHO execution condition, and this embodiment of the present application does not limit this.

[0321] Optionally, the second condition can also be used together with the CHO execution condition / CHO evaluation condition. Specifically, the terminal device can also determine whether the target base station or target cell meets the CHO execution condition / CHO evaluation condition. When the target base station or target cell meets the CHO execution condition / CHO evaluation condition, the terminal device can directly perform cell switching. Alternatively, when the target base station or target cell meets the CHO execution condition / CHO evaluation condition, and the target base station or target cell does not use any of the functions of NES, OFF, DTX ON, DTX OFF, DRX ON, and DRX OFF, the terminal device can perform cell switching. Alternatively, when the target base station or target cell meets the CHO execution condition, and the target base station or target cell is in any of the states of non-NES state, ON state, DTX ON state, DTX OFF state, DRX ON state, and DRX OFF state, the terminal device can perform cell switching. Alternatively, when the target base station or target cell meets the CHO execution condition / CHO evaluation condition and the target base station or target cell does not support any of the functions NES, OFF, DTX ON, DTX OFF, DRX ON, and DRX OFF, the terminal device can perform cell switching.

[0324] The terminal device supports NES capabilities;

[0325] The terminal device has no transmission requirements within the first period;

[0326] The terminal device receives a handover configuration for one or more candidate target cells;

[0327] The wireless link of the terminal device fails;

[0328] When the source base station or source cell of the terminal device is in any of the following states: NES state, OFF state, DTX ON state, DTX OFF state, DRX ON state, or DRX OFF state, a wireless link failure occurs.

[0329] Optionally, the first duration can be predefined, or independently configured, or configured through the above-mentioned switching configuration information, or configured to the terminal device by the source base station or source cell when the source base station or source cell switches from other states to any of the NES state, OFF state, DTX ON state, DTX OFF state, DRX ON state, and DRX OFF state. The embodiments of the present application do not impose any restrictions on this.

[0330] In some embodiments, the fourth condition may include:

[0331] The terminal device receives the third indication information; the third indication information is used for one or more of the following:

[0332] instructing or triggering the terminal device to perform handover evaluation;

[0333] Instructing the terminal device to perform or trigger a handover using the handover configuration information;

[0334] Instructing the terminal device to perform handover based on the configuration information of the pre-configured target cell;

[0335] Indicates the network capability or network type of the source base station or source cell;

[0336] Indicates whether the source base station or source cell uses any of the following functions: NES, OFF, DTX ON, DTX OFF, DRX ON, or DRX OFF;

[0337] Indicates any one of the following states: NES state, OFF state, DTX ON state, DTX OFF state, DRX ON state, and DRX OFF state of the source base station or source cell;

[0338] Indicates the available time or non-energy-saving time or working time of the source base station or source cell;

[0339] Indicates the unavailable time, energy-saving time, or shutdown time of the source base station or source cell;

[0340] Indicates the information transmission time between the source base station or source cell and the terminal;

[0341] Indicates the information transmission time between the target base station or target cell and the terminal;

[0342] Indicates the available time or non-energy-saving time or working time of the target base station or target cell;

[0343] Indicate the unavailable time, energy-saving time, or shutdown time of the target base station or target cell;

[0354] Instructs the terminal device to perform switching based on network status, network capabilities, network type, and NES information;

[0355] Instructs the terminal device supporting NES capability to perform the switching process.

[0356] Optionally, the third indication information may be sent by the source base station or source cell to the terminal device. The source base station or source cell may send the third indication information via group signaling or via a dedicated message, which is not limited in the embodiment of the present application.

[0357] It should be noted that the above-mentioned conditions related to network status, network capability, network type, and NES information can be indicated by the above-mentioned fourth indication information, or by other separate indication information, or predefined or preconfigured, and the embodiments of the present application do not limit this.

[0358] The above embodiment is described below with reference to the application scenario shown in FIG4 . Referring to FIG4 , the current serving cell of UE1 is cell 1, and cell 1 includes three neighboring cells, namely cell 2, cell 3, and cell 4. The base station 1 corresponding to cell 1 can send handover configuration information to UE1, and configure the relevant configuration information of three candidate target cells (cell 2, cell 3, and cell 4) to UE1 through the handover configuration information. In addition, the handover configuration information also includes the conditions that the terminal device needs to meet to perform cell handover. In this example, the conditions that the terminal device needs to meet to perform cell handover included in the handover configuration information may include: the source cell is in the NES state, and the target cell is in the non-NES state. Accordingly, after receiving the handover configuration information, UE1 can monitor the NES states of cell 1, cell 2, cell 3, and cell 4 based on the handover configuration information. When UE1 detects that cell 1 enters the NES state and any one of cell 2, cell 3, and cell 4 remains in the non-NES state, UE1 can trigger cell handover at this time.

[0359] In summary, the terminal device can perform different types of cell switching when one or more of the first to fourth conditions are met, thereby improving the flexibility of cell switching.

[0360] It should be noted that in the embodiment of the present application, after receiving the handover configuration information, the terminal device may save the handover configuration information, but does not perform the cell handover corresponding to the handover configuration information. Instead, it performs the cell handover when one or more of the above four conditions are met.

[0361] In some embodiments, the cell handover includes at least one of the following: CHO handover, handover based on handover configuration information, and handover with multiple candidate target cells pre-configured.

[0362] The CHO switching may be performed based on a CHO execution condition / CHO evaluation condition (trigger condition), wherein the CHO execution condition / CHO evaluation condition may be carried in a CHO command.

[0363] In some embodiments, the handover configuration information may further include one or more of the following:

[0364] an execution condition / evaluation condition for each of the one or more candidate target cells;

[0365] Execution conditions / evaluation conditions of all candidate target cells in one or more candidate target cells.

[0366] It should be understood that the terminal device can determine which target cell to access based on the execution conditions / evaluation conditions in the switching configuration information. That is, when the execution conditions / evaluation conditions of a candidate target cell are met, the terminal device can actively switch to the candidate target cell.

[0367] It should be noted that handover based on handover configuration information can be handover based on execution conditions / evaluation conditions configured in the handover configuration information. In other words, handover based on handover configuration information can have its own unique handover conditions / evaluation conditions. Handover based on handover configuration information can also be referred to as CHO-like handover.

[0368] Optionally, the execution conditions / evaluation conditions of the one or more candidate target cells configured in the handover configuration information may be the same or different. The source base station or source cell may configure a separate execution condition / evaluation condition for each of the one or more candidate target cells, or uniformly configure one execution condition / evaluation condition for the one or more candidate target cells.

[0369] In some embodiments, the execution conditions / evaluation conditions for the multiple candidate target cells may be preconfigured. That is, the execution conditions / evaluation conditions for the multiple candidate target cells are neither carried in the CHO command nor in the handover configuration information. The execution conditions / evaluation conditions for the multiple candidate target cells may be configured independently by the base station.

[0370] The pre-configured handover of multiple candidate target cells may be a handover performed by the terminal device according to pre-configured execution conditions / evaluation conditions.

[0371] In a possible implementation, the terminal device may directly perform cell switching when one or more of the first to fourth conditions mentioned above are met.

[0372] In another possible implementation, the terminal device can determine whether the execution condition / evaluation condition of the target cell is met when one or more of the above-mentioned first to fourth conditions are met, so as to select a target cell for switching.

[0373] Optionally, the terminal device may measure one or more candidate target cells and obtain measurement results. When one or more of the first to fourth conditions are met, and the measurement result of a candidate target cell meets the execution condition / evaluation condition of the target cell, the candidate target cell is used as the target cell, and the terminal device may be switched to the candidate target cell.

[0374] Optionally, the terminal device may perform CHO switching when one or more of the first to fourth conditions are met. It is understandable that one or more of the first to fourth conditions may be used together with existing CHO execution conditions.

[0375] Optionally, the terminal device may perform handover based on the handover configuration information when one or more of the first to fourth conditions are met. It is understandable that the terminal device may perform the CHO-like handover mentioned above when one or more of the first to fourth conditions are met. It can be seen that the first, second, third, and fourth conditions may also be decoupled from the CHO execution conditions, and CHO handover and CHO-like handover each have their own execution conditions.

[0376] Optionally, when one or more of the first to fourth conditions mentioned above are met, pre-configured handover of multiple candidate target cells is performed.

[0377] Optionally, when one or more of the first condition, the second condition, the third condition and the fourth condition are met, but no candidate target cell meets the execution condition / evaluation condition of the target cell, the terminal device may not perform cell switching.

[0378] It should be noted that the execution condition / evaluation condition of the target cell may be a CHO execution condition (trigger condition) / CHO evaluation condition. The CHO execution condition / CHO evaluation condition may be configured in the CHO configuration information. The execution condition / evaluation condition of the target cell may be an execution condition / evaluation condition configured in the handover configuration information.

[0379] It can be seen that the terminal device can perform different types of cell switching when one or more of the first to fourth conditions are met, thereby improving the flexibility of cell switching.

[0380] In some embodiments, before the terminal device performs cell switching, it may further perform the following steps:

[0381] After receiving the handover configuration information, the terminal device performs measurement based on the handover configuration information to obtain a measurement result;

[0382] or,

[0383] After receiving the handover configuration information and the state of the source cell is switched to any one of the NES state, OFF state, DTX ON state, DTX OFF state, DRX ON state, and DRX OFF state, the terminal device performs measurement based on the handover configuration information to obtain a measurement result;

[0384] or,

[0385] When the terminal device receives the switching configuration information and triggers the switching, it performs measurement based on the switching configuration information to obtain the measurement result.

[0386] It should be understood that the terminal device measures one or more candidate target cells based on the configuration information of one or more candidate cells configured by the handover configuration information.

[0387] In a possible implementation, after receiving the handover configuration information, the terminal device may immediately start to perform measurements based on the handover configuration information to obtain measurement results.

[0388] In another possible implementation, upon receiving the handover configuration information, the terminal device may not start to perform measurement immediately, but instead perform measurement based on the handover configuration information when certain conditions are met.

[0389] Optionally, after receiving the switching configuration information and the state of the source base station or source cell is switched to any one of the NES state, OFF state, DTX ON state, DTX OFF state, DRX ON state, and DRX OFF state, the terminal device can perform measurements based on the switching configuration information to obtain measurement results.

[0390] Optionally, when the terminal device receives the switching configuration information and triggers the switching, it may also perform measurement based on the switching configuration information to obtain a measurement result.

[0391] In some embodiments, the handover configuration information includes one or more sets of execution conditions / evaluation conditions; or, the execution conditions / evaluation conditions of the target cell include one or more sets.

[0392] Optionally, the above one or more sets of execution conditions / evaluation conditions may be generated by a source base station or a source cell.

[0393] It should be noted that one or more candidate target cells may have independent execution conditions / evaluation conditions, or may share the same execution conditions / evaluation conditions.

[0394] Optionally, the handover configuration information includes one or more execution conditions / evaluation conditions for all candidate target cells. The handover configuration information may also configure one or more execution conditions / evaluation conditions for each target candidate cell, which is not limited in this embodiment of the present application.

[0395] In some embodiments, the terminal device may use the first set of execution conditions / evaluation conditions to perform cell switching or switching evaluation.

[0396] It should be noted that when the handover configuration information configures a set of execution conditions / evaluation conditions, the execution conditions / evaluation conditions may be the first set of execution conditions / evaluation conditions. In this case, the terminal device may perform cell handover based on the configured first set of execution conditions / evaluation conditions. Alternatively, when the handover configuration information configures multiple sets of execution conditions / evaluation conditions, the terminal device may only use the first set of execution conditions / evaluation conditions to perform cell handover.

[0397] Optionally, the first set of execution conditions / evaluation conditions in the embodiment of the present application may be execution conditions / evaluation conditions that enable the terminal device to quickly switch to the target cell.

[0398] Among them, the threshold parameters or other parameters in the first set of execution conditions / evaluation conditions can be set differently from the parameters in the existing execution conditions / evaluation conditions, so that the terminal device can quickly switch to the target cell. Exemplarily, the first set of execution conditions / evaluation conditions may include an A3 event or an A5 event, wherein, compared with the A3 event in the existing CHO execution conditions / CHO evaluation conditions, the A3 event in the first set of execution conditions / evaluation conditions has a lower threshold than the threshold of the CHO execution conditions / CHO evaluation conditions. Compared with the A5 event in the existing CHO execution conditions / CHO evaluation conditions, the A5 event in the first set of execution conditions / evaluation conditions has a higher threshold 1 configured in the first set of execution conditions / evaluation conditions than the threshold 1 of the CHO execution conditions / CHO evaluation conditions, and the threshold 2 configured in the first set of execution conditions / evaluation conditions is lower than the threshold 2 of the CHO execution conditions / CHO evaluation conditions.

[0399] The following describes in detail how the terminal device uses the first set of execution conditions / evaluation conditions to perform cell switching or switching evaluation.

[0400] In some embodiments, the terminal device uses the first set of execution conditions / evaluation conditions to perform cell handover or handover evaluation, which may include at least one of the following:

[0401] In the case of using the first set of execution conditions / evaluation conditions, if the first set of execution conditions / evaluation conditions are met, the terminal device is handed over to the target cell;

[0402] When the first set of execution conditions / evaluation conditions is used, if one or more of the first condition, the second condition, the third condition and the fourth condition are met, and the first set of execution conditions / evaluation conditions are met, the terminal device is handed over to the target cell;

[0403] When the first set of execution conditions / evaluation conditions is used, if one or more candidate target cells or all candidate target cells do not meet the first set of execution conditions / evaluation conditions, the terminal device selects a candidate target cell with the best measurement result from the one or more candidate target cells for handover;

[0404] When the first set of execution conditions / evaluation conditions is used, if one or more candidate target cells or all candidate target cells do not meet the first set of execution conditions / evaluation conditions, the terminal device selects a target cell from the candidate target cells according to the ranking of the measurement results in the one or more candidate target cells, and / or switches to the target cell;

[0405] When the first set of execution conditions / evaluation conditions is used, if one or more candidate target cells or all candidate target cells do not meet the first set of execution conditions / evaluation conditions, the terminal device selects a target cell from the candidate target cells according to the priority or priority order of the one or more candidate target cells, and / or switches to the target cell;

[0406] When the first set of execution conditions / evaluation conditions is used, if one or more of the first condition, the second condition, the third condition, and the fourth condition are met, and one or more candidate target cells or all candidate target cells do not meet the first set of execution conditions / evaluation conditions, the terminal device selects the candidate target cell with the best measurement result from the one or more candidate target cells for handover;

[0407] When the first set of execution conditions / evaluation conditions is used, if one or more of the first condition, the second condition, the third condition, and the fourth condition are met, and one or more candidate target cells or all candidate target cells do not meet the first set of execution conditions / evaluation conditions, the terminal device selects the target cell from the candidate target cells according to the ranking of the measurement results in the one or more candidate target cells, and / or switches to the target cell;

[0408] When the first set of execution conditions / evaluation conditions is used, if one or more of the first condition, the second condition, the third condition and the fourth condition are met, and one or more candidate target cells or all candidate target cells do not meet the first set of execution conditions / evaluation conditions, the terminal device selects a target cell from the candidate target cells according to the priority or priority order of the one or more candidate target cells, and / or switches to the target cell;

[0409] In the case where a set of execution conditions / evaluation conditions are configured, if the first set of execution conditions / evaluation conditions is met, the terminal device is handed over to the target cell;

[0410] When a set of execution conditions / evaluation conditions is configured, if one or more of the first condition, the second condition, the third condition, and the fourth condition are met, and the first set of execution conditions / evaluation conditions are met, the terminal device is handed over to the target cell;

[0411] When a set of execution conditions / evaluation conditions is configured, if one or more candidate target cells or all candidate target cells do not meet the first set of execution conditions / evaluation conditions, the terminal device selects a candidate target cell with the best measurement result from the one or more candidate target cells for handover;

[0412] When a set of execution conditions / evaluation conditions is configured, if one or more candidate target cells or all candidate target cells do not meet the first set of execution conditions / evaluation conditions, the terminal device selects the target cell from the candidate target cells according to the order of the measurement results in the one or more candidate target cells, and / or switches to the target cell;

[0413] When a set of execution conditions / evaluation conditions is configured, if one or more candidate target cells or all candidate target cells do not meet the first set of execution conditions / evaluation conditions, the terminal device selects the target cell from the candidate target cells according to the priority or priority order of the one or more candidate target cells, and / or switches to the target cell;

[0414] When a set of execution conditions / evaluation conditions is configured, if one or more of the first condition, the second condition, the third condition, and the fourth condition are met, and one or more candidate target cells or all candidate target cells do not meet the first set of execution conditions / evaluation conditions, the terminal device selects a candidate target cell with the best measurement result from the one or more candidate target cells for handover;

[0415] When a set of execution conditions / evaluation conditions is configured, if one or more of the first condition, the second condition, the third condition, and the fourth condition are met, and one or more candidate target cells or all candidate target cells do not meet the first set of execution conditions / evaluation conditions, the terminal device selects a target cell from the candidate target cells according to the ranking of the measurement results in the one or more candidate target cells, and / or switches to the target cell;

[0416] When a set of execution conditions / evaluation conditions are configured, if one or more of the first condition, the second condition, the third condition and the fourth condition are met, and one or more candidate target cells or all candidate target cells do not meet the first set of execution conditions / evaluation conditions, the terminal device selects a target cell from the candidate target cells according to the priority or priority order of one or more candidate target cells, and / or switches to the target cell.

[0417] In short, in one possible implementation, if the measurement result of a candidate target cell meets the first set of execution conditions / evaluation conditions of the target cell, the terminal device may select the candidate target cell as the final handover target cell and directly handover to the target cell. If the measurement result of no candidate target cell meets the first set of execution conditions / evaluation conditions, the terminal device may perform one or more of the following:

[0418] Select the target cell with the best measurement result and switch to the target cell;

[0419] selecting a target cell from candidate target cells according to the ranking of the measurement results, and / or switching to the target cell;

[0420] A target cell is selected from candidate target cells according to a priority or priority order, and / or a handover is performed to the target cell.

[0421] In another possible implementation, the first set of execution conditions / evaluation conditions may be used in combination with one or more of the first, second, third and fourth conditions in the above-mentioned embodiments. Specifically, the terminal device may use the candidate target cell as the target cell for final switching when one or more of the first, second, third and fourth conditions are met and the measurement result of a candidate target cell meets the first set of execution conditions / evaluation conditions. The terminal device may perform one or more of the following when one or more of the first, second, third and fourth conditions are met, but no measurement result of the candidate target cell meets the first set of execution conditions / evaluation conditions:

[0422] Select the target cell with the best measurement result and switch to the target cell;

[0423] selecting a target cell from candidate target cells according to the ranking of the measurement results, and / or switching to the target cell;

[0424] A target cell is selected from candidate target cells according to a priority or priority order, and / or a handover is performed to the target cell.

[0425] It should be noted that priority can be understood as an absolute level, and priority order can be understood as a relative level, that is, the priority order of each candidate target cell is defined relative to other candidate target cells.

[0426] Optionally, the priority or priority order of the candidate target cells may be network-configured. In some embodiments, the priority or priority order of the candidate target cells is indicated by at least one of the following information sent by the source base station:

[0427] Dedicated signaling, system information, group signaling, handover configuration information, CHO configuration information.

[0428] It should be noted that the terminal device selects a target cell from the candidate target cells based on the ranking of the measurement results. It may be to select the second or third candidate target cell ranked from the candidate target cells as the target cell for switching, so as to avoid congestion of the candidate target cell with the best measurement result. The embodiment of the present application does not limit this.

[0449] In the second case, if one or more candidate target cells or all candidate target cells do not meet the CHO execution condition / CHO evaluation condition, the terminal device performs any one of the following: the terminal device selects the candidate target cell with the best measurement result from one or more candidate target cells for switching; or, the terminal device selects the target cell from the candidate target cells according to the ranking of the measurement results in the one or more candidate target cells, and / or switches to the target cell; or, the terminal device selects the target cell from the candidate target cells according to the priority or priority order of the one or more candidate target cells, and / or switches to the target cell;

[0451] In the second case, if one or more candidate target cells or all candidate target cells meet the second set of execution conditions / evaluation conditions, the second set of execution conditions / evaluation conditions are used to perform cell handover or handover evaluation;

[0452] In the second case, if the first set of execution conditions / evaluation conditions is not met, the second set of execution conditions / evaluation conditions is used to perform cell handover or handover evaluation;

[0453] In the second case, if one or more of the first condition, the second condition, the third condition and the fourth condition are met, and the first set of execution conditions / evaluation conditions are not met, the second set of execution conditions / evaluation conditions are used to perform cell switching;

[0454] In the second case, if the first set of execution conditions / evaluation conditions is not met, the terminal device performs any one of the following: the terminal device selects a candidate target cell with the best measurement result from one or more candidate target cells for handover; or, the terminal device selects a target cell from the candidate target cells according to the ranking of the measurement results of the one or more candidate target cells, and / or switches to the target cell; or, the terminal device selects a target cell from the candidate target cells according to the priority or priority order of the one or more candidate target cells, and / or switches to the target cell;

[0456] It should be noted that the handover configuration information may include two sets of execution conditions / handover conditions. The first set of execution conditions / evaluation conditions may be execution conditions / evaluation conditions that enable the terminal device to quickly switch to the target cell. The second set of execution conditions / evaluation conditions may be existing execution conditions / evaluation conditions, such as CHO execution conditions / CHO evaluation conditions.

[0457] Among them, the threshold parameters or other parameters in the first set of execution conditions / evaluation conditions can be set differently from the parameters in the second set of execution conditions / evaluation conditions, so that the terminal device can quickly switch to the target cell. Exemplarily, the first set of execution conditions / evaluation conditions and the second set of execution conditions / evaluation conditions can include A3 events or A5 events, wherein, compared with the A3 events in the second set of execution conditions / evaluation conditions, the threshold configured in the first set of execution conditions / evaluation conditions is lower than the threshold of the second set of execution conditions / evaluation conditions. Compared with the A5 events in the second set of execution conditions / evaluation conditions, the threshold 1 configured in the first set of execution conditions / evaluation conditions is higher than the threshold 1 of the second set of execution conditions / evaluation conditions, and the threshold 2 configured in the first set of execution conditions / evaluation conditions is lower than the threshold 2 of the second set of execution conditions / evaluation conditions.

[0459] The source base station / source cell is in, is about to be in, or is temporarily suspended from leaving any of the following states: OFF state, NES state, DTX ON state, DTX OFF state, DRX ON state, or DRX OFF state;

[0460] The source base station / source cell uses any one of the functions of NES, OFF, DTX ON, DTX OFF, DRX ON, and DRX OFF.

[0461] That is to say, when the source base station or source cell is able to stop providing all services to the terminal device, or stop providing unnecessary services, the terminal device can use the first set of execution conditions or evaluation conditions to perform cell switching, so that the terminal device can quickly switch to the target cell, avoiding the terminal device being disconnected from the network, resulting in call interruption, data jamming and other problems.

[0462] Optionally, the second condition may include one or more of the following:

[0463] The source base station / source cell is in, is about to be in, or is temporarily leaving any of the following states: ON state, non-NES state, DTX ON state, DTX OFF state, DRX ON state, or DRX OFF state;

[0464] The source base station / source cell uses any function among non-NES, ON, DTX ON, DTX OFF, DRX ON, and DRX OFF.

[0465] That is to say, when the source base station or source cell is able to provide services, the terminal device can use the second set of execution conditions or evaluation conditions to perform cell switching and perform cell switching normally.

[0466] In some embodiments, the method further comprises at least one of the following:

[0467] In the case where one or more sets of execution conditions / evaluation conditions are not configured, or in the case where one or more sets of execution conditions / evaluation conditions are not activated or enabled, if one or more candidate target cells or all candidate target cells do not meet the execution conditions / evaluation conditions of the target cell, the terminal device selects the candidate target cell with the best measurement result from the one or more candidate target cells for handover or handover evaluation;

[0473] It should be noted that the source base station or source cell may not configure one or more sets of execution conditions / evaluation conditions for the terminal device in the handover configuration information. In addition, the one or more sets of execution conditions / evaluation conditions configured in the handover configuration information may be activated or enabled for use by the terminal device.

[0474] In the implementation of this application, the terminal device can perform switching when one or more sets of execution conditions / evaluation conditions are not configured in the switching configuration information, or when one or more sets of execution conditions / evaluation conditions are not activated or enabled.

[0475] In one possible implementation, when one or more sets of execution conditions / evaluation conditions are not configured in the handover configuration information, or when one or more sets of execution conditions / evaluation conditions are not activated or enabled, the terminal device may perform any of the following:

[0478] A target cell is selected from candidate target cells according to a priority or priority order, and / or a handover is performed to the target cell.

[0479] In another possible implementation, when one or more sets of execution conditions / evaluation conditions are not configured in the switching configuration information, or when one or more sets of execution conditions / evaluation conditions are not activated or enabled, the terminal device can determine whether the target candidate cell meets the execution conditions / evaluation conditions of the target cell. The execution conditions / evaluation conditions of the target cell here can be CHO execution conditions / CHO evaluation conditions, or can be activated or enabled execution conditions / evaluation conditions, and the embodiments of the present application do not limit this. When one or more candidate target cells or all candidate target cells do not meet the execution conditions / evaluation conditions of the target cell, the terminal device can perform any of the following:

[0482] A target cell is selected from candidate target cells according to a priority or priority order, and / or a handover is performed to the target cell.

[0483] In another possible implementation, the terminal device may also make a judgment in combination with the first to fourth conditions in the above embodiment. Specifically, when one or more sets of execution conditions / evaluation conditions are not configured in the handover configuration information, or when one or more sets of execution conditions / evaluation conditions are not activated or enabled, if one or more of the first, second, third and fourth conditions are met, and one or more candidate target cells or all candidate target cells do not meet the execution conditions / evaluation conditions of the target cell, the terminal device may perform any of the following:

[0486] A target cell is selected from candidate target cells according to a priority or priority order, and / or a handover is performed to the target cell.

[0487] It should be noted that the relevant description of the terminal device performing the above operations can be understood by referring to the description in the above embodiments. For the sake of brevity, it will not be repeated here.

[0488] Optionally, before executing cell switching or before satisfying execution conditions / evaluation conditions, the terminal device receives a HO command, and the terminal device executes the HO process, ignores, disregards, or deletes the received switching configuration information, and / or terminates the execution of the cell switching corresponding to the switching configuration information.

[0598] Optionally, the fourth indication information may be sent by a source base station or a source cell. The source base station or the source cell may send the fourth indication information via a multicast message or a dedicated message, which is not limited in the embodiment of the present application.

[0599] Among them, the above-mentioned conditions related to network status, network capability, network type, and NES information can be indicated by the fourth indication information, or by other separate indication information, or predefined or preconfigured, and the embodiments of the present application do not limit this.

[0600] It should be noted that the description of the eighth condition can be understood by referring to the description of the fourth condition in the above embodiment. For the sake of brevity, it will not be repeated here.

[0601] The above embodiment is described below in conjunction with the application scenario shown in Figure 5. Referring to Figure 5, the current serving cell of UE1 is cell 1, and the neighboring cell of cell 1 is cell 2. The base station 1 corresponding to cell 1 can send switching configuration information to UE1, and configure the candidate target cell to UE1 as the relevant configuration information of cell 2 through the switching configuration information. In addition, the switching configuration information also includes the conditions that the terminal device needs to meet to perform cell switching. In this example, the conditions that the terminal device needs to meet to perform cell switching included in the switching configuration information may include: the source cell is in the NES state. After receiving the switching configuration information, UE1 can monitor the current status of cell 1 and cell 2 based on the switching configuration information. When it is detected that cell 1 is in the NES state, UE1 can switch to cell 2. When it is detected that cell 2 is in the NES state, UE1 switches from cell 2 to cell 1. Therefore, when cell 1 and cell 2 are in the NES state at the same time, UE1 will perform ping-pong switching.

[0602] In this exemplary scenario, the terminal device can determine whether to terminate / exit cell switching based on the sixth condition. The sixth condition may include the NES state of the target cell. Based on this, UE1 can perform cell switching in combination with the conditions that the terminal device configured in the switching configuration information needs to meet, as well as the sixth condition. Specifically, when UE1 detects that cell 1 enters the NES state and meets the conditions configured in the switching configuration information, UE1 triggers cell switching. At the same time, when UE1 detects that the target cell is also in the NES state and meets the sixth condition, UE1 can terminate the cell switching.

[0603] In summary, the wireless communication method provided in the embodiment of the present application can provide a terminal device with a method for exiting / terminating cell switching, thereby avoiding the problem of ping-pong switching of the terminal device and improving communication performance. It should be noted that Example 2 can be implemented alone or in combination with other embodiments, and the embodiment of the present application does not limit this.

[0604] Example 3

[0605] This embodiment will introduce in detail the way in which the terminal device selects or determines the target base station or target cell.

[0606] In some embodiments, the terminal device may select or determine the target base station / target cell based on one or more of the following:

[0607] Channel quality, priority, priority order, number of target cells that meet the conditions, network status of the target base station or target cell, network capability, network type, NES information, available time of the target base station or target cell, and identification indication of the target base station or target cell.

[0608] It should be noted that, for the related descriptions of network status, network capability, network type, and NES information, reference can be made to the descriptions of network status, network capability, network type, and NES information in the above embodiments, which will not be repeated here for the sake of brevity.

[0609] It is understandable that in one possible implementation, the terminal device can select or determine the target base station or target cell according to preset rules. Exemplarily, the terminal device can measure one or more candidate target cells based on the switching configuration carried in the switching configuration information to obtain the channel quality of one or more candidate target cells. The terminal device can select the candidate target base station / candidate target cell with the best, second best, or a specific order of channel quality as the target base station / target cell for switching. In addition, the terminal device can also select the target base station / target cell for final switching from the candidate target base stations / candidate target cells according to the priority / priority order. The terminal device can also consider the relevant conditions of network energy saving and select the target base station / target cell according to the network status, network capability, network type, NES information, and available time of the candidate target base station or candidate target cell of the candidate target base station or candidate target cell.

[0633] The target base station or target cell is a base station or cell supporting the second protocol version;

[0634] The second channel quality satisfies the CHO execution condition; the second channel quality is the channel quality between the terminal device and the target base station or target cell;

[0635] The second channel quality is greater than or equal to a sixth threshold;

[0636] The second channel quality is greater than or equal to the third channel quality, where the third channel quality is the channel quality between the terminal device and the candidate target cell in the NES state;

[0637] The difference between the second channel quality and the third channel quality is less than or equal to a seventh threshold;

[0638] The duration during which the difference between the second channel quality and the third channel quality is less than or equal to the seventh threshold is greater than the seventh duration;

[0639] There are multiple target cells that meet the handover execution / evaluation conditions;

[0640] There are multiple target cells that meet the handover execution / evaluation conditions, and the channel quality difference between the multiple candidate target cells is less than an eighth threshold;

[0641] There are multiple target cells that meet the handover execution / evaluation conditions, and the channel quality difference between the candidate target cells with the best channel quality among the multiple candidate target cells is less than an eighth threshold;

[0642] The number of candidate target cells that meet the channel quality condition includes multiple;

[0643] The number of candidate target cells that meet the channel quality condition includes multiple, and the channel quality difference of the multiple candidate target cells is less than an eighth threshold;

[0644] The number of candidate target cells that meet the channel quality condition includes multiple, and the channel quality difference between the candidate target cells with the best channel quality among the multiple candidate target cells is less than an eighth threshold;

[0645] The target base station or target cell is a cell having a priority greater than the first priority;

[0646] The target base station or target cell is not a low priority cell;

[0647] The target base station or target cell is the cell with the highest priority.

[0648] It should be noted that each candidate target base station or candidate target cell is configured with a corresponding priority or priority order, wherein the priority can be understood as an absolute level and the priority order can be understood as a relative level.

[0649] In some embodiments, the priority or priority order of the candidate target base station or candidate target cell is indicated by at least one of the following information sent by the source base station:

[0650] Dedicated signaling, system information, group signaling, handover configuration information, CHO configuration information.

[0651] It is understandable that the network may indicate the priority / priority order of the candidate target base station or candidate target cell to the terminal device separately. The network may also indicate the priority / priority order of the candidate target base station or candidate target cell in the handover configuration information or CHO configuration information.

[0652] Optionally, the network may indicate the priority / priority order of only some candidate target base stations or candidate target cells. Exemplarily, the network may indicate the priority / priority order of candidate target base stations or candidate target cells in the NES state through at least one of the above information, and the network may indicate which candidate target base stations or candidate target cells in the NES state are given low priority through at least one of the above information.

[0653] Optionally, regarding the use of the priority / priority order of the candidate target base station or candidate target cell, or whether to select the target base station / target cell to be switched based on the priority / priority order of the selected target base station or candidate target cell, it can be used in the following scenarios:

[0654] There are multiple target cells that meet the handover execution / evaluation conditions;

[0655] There are multiple target cells that meet the handover execution / evaluation conditions, and the channel quality difference between the multiple candidate target cells is less than an eighth threshold;

[0659] The number of candidate target cells that meet the channel quality condition includes multiple, and the channel quality difference between the candidate target cells with the best channel quality among the multiple candidate target cells is less than an eighth threshold.

[0660] It should be noted that the above-mentioned handover execution / evaluation condition can be the handover execution / evaluation condition carried in the handover configuration information, or the handover execution / evaluation condition carried in the CHO configuration information, or the pre-configured handover execution / evaluation condition, and the embodiment of the present application does not limit this. In addition, the above-mentioned channel quality condition can be determined based on the channel quality ranking (rank) value of multiple candidate target cells. The above-mentioned channel quality difference can be the difference in actual channel quality or the difference in channel quality rank value, and the embodiment of the present application does not limit this.

[0661] In another possible implementation, the target base station / target cell may be configured by the network, and the terminal device may determine the target base station or target cell to be switched based on an identification indication of the target base station / target cell.

[0662] Optionally, the wireless communication method provided in the embodiment of the present application may further include the following:

[0663] The terminal device receives the indication information sent by the source base station, and / or selects or determines the target base station / target cell according to the indication information sent by the source base station;

[0664] The indication information carries the identifier of the target base station / target cell, or the indication information is used to indicate the cell to which the terminal device switches.

[0665] It should be noted that the indication information here can be new indication information, or it can be any one of the first indication information, the second indication information, the third indication information, and the fourth indication information in the above embodiment, and the embodiment of the present application does not limit this.

[0666] In summary, the terminal device can consider different scenarios and select an appropriate target base station or target cell. This improves the switching flexibility of the terminal device. It should be noted that Example 3 can be implemented alone or in combination with other embodiments, and this application embodiment does not limit this.

[0667] Example 4

[0668] This embodiment introduces in detail the signaling transmission method during the cell switching process.

[0669] In an embodiment of the present application, the wireless communication method may include the following steps:

[0670] Step 210, the terminal device receives the first signaling sent by the source base station or source cell through group signaling and / or dedicated message; the first signaling includes one or more of switching configuration information, switching command, first indication information, second indication information, third indication information, and fourth indication information.

[0671] It should be noted that the switching command may include a CHO command or a common switching command, and the embodiment of the present application does not limit this.

[0672] Optionally, the group signaling may include group DCI, group MAC CE message, group RRC message, or multicast information, etc., which is not limited in the embodiment of the present application. The dedicated message may include RRC dedicated signaling, dedicated DCI, dedicated MAC CE message, etc., which is not limited in the embodiment of the present application.

[0673] It should be understood that the source base station can send group signaling to multiple terminal devices within the coverage area of ​​the source cell, and configure the information of the cell switching process for multiple terminal devices at the same time through group signaling to reduce signaling overhead. The source base station can also configure the information of the cell switching process for the terminal device separately through dedicated messages to avoid configuration failure and ensure the successful switching of the terminal device.

[0674] It should be noted that the source base station or source cell may use different transmission modes to send the first signaling or part of the information in the first signaling to different terminal devices.

[0675] In some embodiments, the transmission method may include at least one of the following:

[0676] The source base station sends the first signaling or part of the first signaling through group signaling;

[0677] The source base station sends the first signaling or part of the first signaling through a dedicated message;

[0678] The source base station repeatedly sends the first signaling or part of the first signaling through group signaling;

[0679] The source base station repeatedly sends the first signaling or part of the first signaling information through a dedicated message.

[0680] For example, as shown in reference Figure 6, the source base station or source cell can send the first signaling or part of the first information to the terminal device in area A through group signaling, and the source base station or source cell can send the first signaling or part of the first signaling to each terminal device in area B through a dedicated message.

[0681] In some embodiments, in the wireless communication method provided in the embodiments of the present application, the terminal device performs reception based on the transmission mode configuration information, where the transmission mode configuration information is used to indicate the transmission mode of the first signaling or the transmission mode of part of the information of the first signaling;

[0682] Among them, the transmission methods of the first signaling corresponding to different terminal devices are the same or different; and / or the transmission methods of all or part of the information of the first signaling are the same or different.

[0683] In some embodiments, the transmission mode configuration information is determined based on any one of the following:

[0684] Predefined, network configuration, preset rules.

[0685] Optionally, the transmission mode configuration information of different terminal devices is the same or different. For example, the transmission mode configuration information of the same type of terminal devices is the same, while the transmission mode configuration information of different types of terminal devices is different. Alternatively, the distance between the terminal device and the source base station is different, and the corresponding transmission mode configuration information is different.

[0686] In one possible implementation, the transmission mode configuration information of the terminal device may be predefined, and the predefinition may be protocol predefined, or predefined between the terminal device and the network. This embodiment of the present application does not impose any restrictions on this.

[0687] For example, the terminal device and the network may predefine a correspondence between the terminal device type and the transmission mode configuration information, so that the terminal device can determine the corresponding transmission mode configuration information based on its type. Alternatively, the terminal device and the network may predefine a correspondence between the distance of the terminal device from the source base station and the transmission mode configuration information, so that the terminal device can determine the corresponding transmission mode configuration information based on its distance from the source base station.

[0688] In another possible implementation, the transmission mode configuration information of the terminal device may be network configured.

[0689] Optionally, the transmission mode configuration information of the terminal device may be generated by a source base station. The source base station may send the transmission mode configuration information to the terminal device.

[0690] Optionally, the source base station may send transmission mode configuration information to the terminal device via RRC dedicated signaling.

[0691] Optionally, the transmission mode configuration information may be public, for example, for a terminal device, or for a source base station, and this embodiment of the present application does not impose any restrictions on this.

[0692] In another possible implementation, the transmission mode configuration information of the terminal device may also be implemented by the terminal device itself. Optionally, the terminal device may determine the transmission mode configuration information according to a preset rule.

[0693] Exemplarily, the terminal device may determine the transmission mode based on the channel quality, path loss information, distance information, and beam information between the terminal device and the source base station or the target base station.

[0694] In some embodiments, the transmission mode configuration information may include area configuration information and / or repeated transmission number information;

[0695] The area configuration information is used to indicate the location information of the terminal device, or to indicate the position relationship and / or orientation relationship between the terminal device and the source base station or source cell;

[0696] The number of repeated transmissions information is used to indicate the number of times the terminal device repeatedly receives, or the number of times the source base station or source cell repeatedly sends information, or the number of times the source base station repeatedly sends the first signaling or part of the information in the first signaling.

[0697] It should be noted that the area configuration information indicates the positional relationship between the terminal device and the source base station or source cell, which may be whether the terminal device is at the center or edge of the source cell, or whether the terminal device is at the center, middle, or edge of the source cell. This embodiment of the present application does not limit this. In addition, the area configuration information indicates the orientation relationship between the terminal device and the source base station or source cell, which may be the beam direction of the terminal device at the source base station, for example, the terminal device is in the east / south / west / north direction of the source base station.

[0698] Optionally, the area configuration information may include one or more. Exemplarily, the area configuration information may include whether the terminal device is in the center, middle, or edge of the source cell, and in which beam direction of the source base station the terminal device is.

[0699] In some embodiments, the zone configuration information may be determined based on one or more of the following:

[0700] Channel quality, path loss information, distance information, and beam information between the terminal device and the source base station or source cell; and / or, channel quality, path loss information, distance information, and beam information between the terminal device and the target base station or target cell.

[0701] In some embodiments, different area configuration information corresponds to different transmission modes.

[0702] Different area configuration information corresponds to different transmission modes, which may include one or more of the following:

[0703] For the first area, the source base station or the source cell sends the first signaling or part of the first signaling information to the terminal device through group signaling;

[0704] For the second area, the source base station or the source cell sends the first signaling or part of the first signaling to the terminal device through a dedicated message, or group signaling and a dedicated message;

[0705] When the terminal device is within the first area, or when the area configuration information indicates that the terminal device is within the first area, the source base station or the source cell sends the first signaling or part of the first signaling to the terminal device through group signaling;

[0706] When the terminal device is within the second area, or when the area configuration information indicates that the terminal device is within the second area, the source base station or the source cell sends the first signaling or part of the first signaling to the terminal device through a dedicated message, or group signaling and a dedicated message.

[0707] Optionally, the first area may be an area with better channel quality, better path loss, shorter distance, or larger beam range. The source base station or source cell may send the first signaling or part of the information in the first signaling to the terminal device in the first area by means of group signaling. The second area may be an area with poor channel quality, poor path loss, longer distance, or smaller beam range. The source base station or source cell may send the first signaling or part of the information in the first signaling to the terminal device in the second area by means of a dedicated message, or group signaling + dedicated message. In this way, the failure of switching information configuration is avoided and the success rate of group switching is improved.

[0708] For example, as shown in reference Figure 6, the source base station can use group signaling to send the first signaling or part of the information in the first signaling in the cell center area, that is, area A, and use a dedicated message in the cell edge area, that is, area B, or use group signaling + dedicated message to send the first signaling or part of the information in the first signaling.

[0709] In addition, the source base station uses group signaling to send the first signaling or part of the information in the first signaling in the direction of cell beam 1 or the east direction, and uses dedicated messages in other areas, or group signaling + dedicated messages to send the first signaling or part of the information in the first signaling.

[0710] Optionally, the information on the number of repeated transmissions may include one or more, which is not limited in the embodiment of the present application.

[0711] In some embodiments, the number of repeated transmissions is the same for different terminal devices;

[0712] Alternatively, different terminal devices may have different information about the number of retransmissions;

[0713] Alternatively, the number of repeated transmission times is different for terminal devices in different areas.

[0714] It can be understood that when the number of repeated transmission times is one, the number of repeated transmission times information can be public, and the number of repeated transmission times information of different terminal devices is the same.

[0715] When there are multiple retransmission counts, the retransmission counts for different terminal devices may be different. For example, the retransmission counts may be different for terminal devices at different times, different types of terminal devices, different configurations of terminal devices, and terminal devices in different areas.

[0716] Exemplarily, the number of repeated transmissions may include N1, where N1 is greater than or equal to 1. The source base station may repeatedly send the first signaling or part of the first signaling N times to all terminal devices within the coverage of the source cell through group signaling or dedicated messages within the entire source cell.

[0717] The number of retransmission times may include N2 and N3, where N2 < N3. As shown in FIG. 6, the source base station may use group signaling to send the first signaling or partial information of the first signaling to the terminal devices in area 1 of the source cell, and the first signaling or partial information of the first signaling is not retransmitted or retransmitted N2 times. The source base station may use group signaling to send the first signaling or partial information of the first signaling to the terminal devices in area 2 of the source cell, and the first signaling or partial information of the first signaling is not retransmitted or retransmitted N3 times.

[0718] The number of retransmission times may include N4, N5, and N6, where N4 < N5 < N6. In the cell center area, group signaling may be used to send the first signaling or partial information of the first signaling, and the first signaling or partial information of the first signaling is not retransmitted or retransmitted N2 times, and the first signaling or partial information of the first signaling is not retransmitted or retransmitted N3 times. In the middle area of the cell, group signaling may be used to send the first signaling or partial information of the first signaling, and the first signaling or partial information of the first signaling is not retransmitted or retransmitted N4 times. In the cell edge area, group signaling may be used to send the first signaling or partial information of the first signaling, and the first signaling or partial information of the first signaling is retransmitted N5 times.

[0719] In some embodiments, the handover configuration information or the transmission mode configuration information is further used to indicate one or more of the following:

[0720] The group to which the terminal device belongs;

[0721] The DCI of the group to which the terminal device belongs;

[0722] The RNTI of the group to which the terminal device belongs.

[0723] It can be understood that the source base station or the source cell may indicate the group of the terminal device and / or the corresponding DCI / RNTI of the group through the handover configuration information or the transmission mode configuration information. In this way, the source base station may use the DCI / RNTI corresponding to each group to send the first signaling or partial information of the first signaling to the terminal devices within the group.

[0724] In some embodiments, the area configuration information is associated with the group to which the terminal device belongs, and / or the number of retransmission times information is associated with the group to which the terminal device belongs.

[0725] It can be understood that the source base station or the source cell may allocate and indicate different groups to the terminal device according to the area configuration information, and / or allocate and indicate different groups to the terminal device according to the number of retransmission times information.

[0726] In some embodiments, the source base station sends the first signaling or part of the first information to the terminal device based on the area configuration information and / or the number of repeated transmissions information of the terminal device. Correspondingly, the terminal device receives the first signaling or part of the first information based on the area configuration information and / or the number of repeated transmissions information.

[0727] In one possible implementation, the source base station may send the first signaling or part of the first information to the terminal device based solely on the area configuration information of the terminal device. Correspondingly, the terminal device receives the first signaling or part of the first signaling based solely on the area configuration information.

[0728] Optionally, when the area configuration information indicates that the terminal device is in the first area, the first signaling or part of the first signaling is sent through group signaling;

[0729] In the case where the area configuration information indicates that the terminal device is within the second area, the first signaling or part of the first signaling information is sent via a dedicated message, or group signaling and a dedicated message.

[0730] Optionally, the first area and the second area can be determined by the source base station based on the channel quality, path loss information, distance information, and beam information between the terminal device and the source base station or source cell; and / or, the channel quality, path loss information, distance information, and beam information between the terminal device and the target base station or target cell.

[0731] Optionally, the first area and the second area may also be determined based on the number range of terminal devices. For example, if the number of terminal devices within the cell is greater than a threshold, group signaling is used to send the first signaling or part of the first signaling. Otherwise, a dedicated message, or both group signaling and dedicated messages, may be used to send the first signaling or part of the first signaling.

[0732] Optionally, the first area and the second area can be determined based on the channel quality, path loss information, distance information, and beam information between the terminal device and the source base station or source cell; and / or the channel quality, path loss information, distance information, and beam information between the terminal device and the target base station or target cell, as well as the number range of terminal devices. Exemplarily, when the number of users in a certain location or direction or channel quality area is greater than a threshold value, group signaling is used to send the first signaling or part of the first signaling information. Otherwise, a dedicated message, or group signaling and dedicated message, can be used to send the first signaling or part of the first signaling information.

[0733] In another possible implementation, when the transmission mode configuration information includes repeated transmission number information, the source base station or source cell sends the first signaling or part of the first signaling according to the repeated transmission number information, and correspondingly, the terminal device receives the first signaling or part of the first signaling according to the repeated transmission number information.

[0734] Optionally, if the number of repeated transmissions information indicates N times, the source base station may repeatedly send the first signaling or part of the first signaling information to the terminal device N times within the source cell.

[0735] In another possible implementation, when the transmission mode configuration information includes repeated transmission count information, the source base station or source cell sends the first signaling or partial information of the first signaling according to the repeated transmission count information and the area configuration information, in accordance with the transmission mode corresponding to the area configuration information and the number of times indicated by the repeated transmission count information. Correspondingly, the terminal device receives the first signaling or partial information of the first signaling according to the repeated transmission count information and the area configuration information, in accordance with the transmission mode corresponding to the area configuration information and the number of times indicated by the repeated transmission count information.

[0736] Exemplarily, as shown in reference figure 6, the number of repeated transmissions may include N2 and N3, N2 is greater than or equal to 1, and N3 is greater than N2. As shown in reference figure 6, the source base station may use group signaling to send the first signaling or part of the first signaling to the terminal device in area A of the source cell, and the first signaling or part of the first signaling is repeatedly sent N2 times. The source base station may use a dedicated message to send the first signaling or part of the first signaling to the terminal device in area B of the source cell, and the first signaling or part of the first signaling is repeatedly sent N3 times.

[0737] In some embodiments, the terminal device may determine the number of receptions based on the channel status between the terminal device and the source base station or source cell; the number of receptions may be less than or equal to the number indicated by the repeated transmission number information.

[0738] It is understood that when the repetition transmission coefficient information indicates N repeated transmissions, the terminal device does not need to receive all repeated transmissions. The terminal device can determine the number of receptions based on the channel state between the terminal device and the source base station or source cell. The number of receptions can be less than or equal to the number indicated by the repetition transmission number information.

[0739] Among them, the channel status between the terminal device and the source base station or source cell may include channel quality, path loss information, distance information, beam information and other information.

[0740] In some embodiments, when the terminal device receives the first signaling or part of the first signaling information once, the terminal device may ignore or not receive the subsequent repeatedly sent signaling.

[0741] In some embodiments, after receiving the first signaling or part of the information of the first signaling once, the terminal device responds to the first signaling or part of the information of the first signaling.

[0742] It is understandable that after receiving the first signaling or part of the first signaling information once, the terminal device can configure the cell switching based on the first signaling or part of the first signaling information.

[0743] In some embodiments, after the source base station or source cell sends the first signaling to the terminal device through group signaling, the method further includes:

[0744] The source base station or source cell determines that the terminal device that failed to successfully perform cell handover, and / or the terminal device connected to the source cell, and / or the terminal device that did not switch;

[0745] The source base station or source cell sends a handover command or a CHO command to the terminal device that did not successfully perform cell handover, and / or the terminal device connected to the source cell, and / or the terminal device that did not switch, or instructs the terminal device to switch through a dedicated message;

[0746] Alternatively, the source base station or source cell sends a switching command or CHO command or instructs the terminal device to switch to the terminal device that failed to successfully switch cells, and / or the terminal device connected to the source cell, and / or the terminal device that did not switch, through repeatedly transmitted group messages.

[0747] It is understandable that the source base station or source cell can determine the terminal devices that have not successfully performed cell switching, and / or the terminal devices connected to the source cell, and / or the terminal devices that have not switched, and re-send the switching command or CHO command to these terminal devices or instruct the terminal devices to switch. Here, the source base station or source cell can re-send the switching command or CHO command to these terminal devices or instruct the terminal devices to switch through a dedicated message. The source base station or source cell can also re-send the switching command or CHO command to these terminal devices or instruct the terminal devices to switch through repeatedly transmitted group signaling. In this way, the failure of the group switching indication can be avoided and the success rate of the group switching can be improved.

[0748] In some embodiments, the above-mentioned terminal devices that failed to successfully perform cell switching, and / or the terminal devices connected to the source cell, and / or the terminal devices that did not switch are determined by the source base station or the source cell based on the seventh indication information sent by the target base station; the seventh indication information is used to indicate the terminal devices that successfully switched, or the terminal devices that established a connection with the target base station or target cell, or the terminal devices that switched to the target base station or target cell.

[0749] It can be understood that the source base station can interact with the target base station and determine the terminal devices that failed to successfully switch cells through the seventh indication information sent by the target base station, and / or the terminal devices connected to the source cell, and / or the terminal devices that did not switch.

[0750] Optionally, the seventh indication information may include identification information of the terminal device that is successfully switched, or identification information of the terminal device that establishes a connection with the target base station or target cell, or identification information of the terminal device that is switched to the target base station or target cell.

[0751] In summary, in the method provided in the embodiment of the present application, different transmission mode configuration information is configured for different terminal devices, which can avoid group switching indication failure and improve the success rate of group switching. It should be noted that Example 4 can be implemented alone or in conjunction with other embodiments, and the embodiment of the present application does not limit this.

[0755] Step 310: The terminal device performs at least one of cell access, access permission, cell selection, and cell reselection according to the fifth indication information.

[0756] In an embodiment of the present application, a terminal device may receive fifth indication information, where the fifth indication information is used for at least one of access, access permission, cell selection, and cell reselection of the first terminal device. Alternatively, the terminal device may determine whether or how to perform at least one of cell access, access permission, cell selection, and cell reselection based on the fifth indication information.

[0757] Optionally, the terminal device may receive fifth indication information sent by the base station. The base station here may be a serving base station of the terminal device. For example, the base station may be a source base station, a target base station, etc. of the terminal device, and this embodiment of the present application does not limit this. Optionally, the base station may send the fifth indication information by means of group signaling or a dedicated message. It should be noted that the manner in which the base station sends the fifth indication information may be determined by the transmission mode configuration information in the above-mentioned embodiment 4. For the relevant description of determining the transmission mode of the fifth indication information, reference may be made to the description in embodiment 4. For the sake of brevity, it will not be repeated here.

[0758] In some embodiments, the fifth indication information is used to indicate whether one or more of the network, frequency, and cell allow the first terminal device to access / select / reselect, or to indicate whether the first terminal device is allowed to access one or more of the network, frequency, and cell.

[0759] In some embodiments, the network, frequency, and cell are one or more of the following:

[0775] Non-first terminal devices are not allowed to reselect one or more of the network, frequency, and cell.

[0776] In some embodiments, the base station does not configure the cell access / selection / reselection parameters for the non-first terminal device. In other words, the non-first terminal device may not be configured, or cannot obtain, or not apply the cell selection / reselection / access parameters.

[0777] It should be noted that the above parameters may be at least one of the parameters for cell selection / reselection / access in the relevant technology. For example, the non-first terminal device may not apply p_Max, or the network / frequency / cell may not satisfy the S criterion (such as not satisfying Srxlev>0AND Squal>0).

[0778] Optionally, parameters that cannot be obtained or are not configured by the non-first terminal device can be processed according to default values ​​(such as 0) or abnormal values ​​or negative infinity.

[0779] Optionally, the fifth indication information may be indicated by one or more of broadcast information, SIB, and MIB. Optionally, the SIB may be an existing SIB or a new SIB.

[0780] In some embodiments, the fifth indication information may be carried through system information or through RRC signaling.

[0781] Exemplarily, the system information may include at least one of MIB, SIB1, SIB2, SIB3, SIB4, SIB5, or a new SIB. That is, the fifth indication information may be carried in at least one of MIB, SIB1, SIB2, SIB3, SIB4, SIB5, or a new SIB.

[0782] It should be noted that the fifth indication information may be indicated alone or together with other indication information.

[0783] In a possible implementation, the fifth indication information may be indicated separately.

[0784] Optionally, if the terminal device receives the fifth indication information, or the fifth indication information appears, or the fifth indication information takes the value of true, it indicates the following: one or more of the network, frequency, and cell allow the first terminal device to access / select / reselect, and / or, one or more of the network, frequency, and cell do not allow non-first terminal devices to access / select / reselect.

[0785] Optionally, if the terminal device does not receive the fifth indication information, or the fifth indication information does not appear, or the value of the fifth indication information is false, the following contents are indicated:

[0798] Alternatively, all terminal devices cannot access / select / reselect one or more of the network, frequency, and cell.

[0799] In another possible implementation, the fifth indication information may reuse other indication information.

[0800] Optionally, the fifth indication information may be indicated together with the access control indication information.

[0801] Optionally, the fifth indication information can be used together with a prohibition indication field in the MIB (such as a cellBarred indication field) or a prohibition indication field in the SIB1 (such as a cellReservedForOtherUse indication field, a cellReservedForOperatorUse indication field, a cellReservedForFutureUse indication field, etc.). Exemplarily, when the cellBarred indication field of the MIB is set to barred, the first terminal device and / or the non-first terminal device needs to further determine whether it is prohibited, or whether access / selection / reselection is allowed, based on the fifth indication information.

[0802] When the cellBarred indication field of MIB is set to barred and the cellReservedForFutureUse indication field in SIB1 is set to true, the first terminal device may not be prohibited, or allowed to access / select / reselect, and / or the non-first terminal device may be prohibited, or not allowed to access / select / reselect.

Alternatively, the terminal device may determine the cell access / selection / reselection operation based on the content indicated by the sixth indication information, whether it is a first terminal device or a non-first terminal device, and whether it supports the energy-saving technology associated with the sixth indication information.

[0837] In addition, the terminal device can perform at least one of cell access, access permission, cell selection and cell reselection in combination with the fifth indication information and the sixth indication information.

[0838] Specifically, when the terminal device is a first terminal device, if the fifth indication information indicates that the first terminal device is allowed to access / select / reselect (or the fifth indication information indicates that non-first terminal devices are not allowed to access / select / reselect) one or more of the above-mentioned networks, frequencies, and cells, the first terminal device also needs to determine whether to allow access / selection / reselection based on the sixth indication information. If the terminal device supports the energy-saving technology associated with the sixth indication information, the terminal device determines to access / select / reselect based on one or more of the above-mentioned networks, frequencies, and cells. If the terminal device does not support the energy-saving technology associated with the sixth indication information, the terminal device determines that access / selection / reselection is not allowed to one or more of the above-mentioned networks, frequencies, and cells.

[0839] In the case that the terminal device is a first terminal device, if the fifth indication information indicates that the first terminal device is not allowed to access / select / reselect (or if the fifth indication information indicates that a non-first terminal device is allowed to access / select / reselect) one or more of the above-mentioned networks, frequencies, and cells, then the first terminal device is not allowed to access / select / reselect one or more of the above-mentioned networks, frequencies, and cells regardless of whether it supports the energy-saving technology associated with the sixth indication information.

[0840] In the case where the terminal device is not the first terminal device, if the fifth indication information indicates that the non-first terminal device allows access / selection / reselection (or if the fifth indication information indicates that the first terminal device does not allow access / selection / reselection), the terminal device also needs to determine whether to allow access / selection / reselection based on the sixth indication information. If the terminal device supports the energy-saving technology associated with the sixth indication information, the terminal device determines that it allows access / selection / reselection of one or more of the above-mentioned networks, frequencies, and cells. If the terminal device does not support the energy-saving technology associated with the sixth indication information, the terminal device determines that it does not allow access / selection / reselection of one or more of the above-mentioned networks, frequencies, and cells.

[0841] In the case that the terminal device is not the first terminal device, if the fifth indication information indicates that the non-first terminal device is not allowed to access / select / reselect (or if the fifth indication information indicates that the first terminal device is allowed to access / select / reselect), the terminal device is not allowed to access / select / reselect one or more of the above-mentioned networks, frequencies, and cells regardless of whether it supports the energy-saving technology associated with the sixth indication information.

[0842] In summary, the method provided in the embodiment of the present application can perform different access / selection / reselection operations for different terminal devices to achieve network energy saving. It should be noted that the above embodiment 5 can be implemented alone or in conjunction with other embodiments, and the embodiment of the present application does not limit this.

[0843] Example 6

[0844] This embodiment will introduce the paging process in detail.

[0845] In one embodiment of the present application, a wireless communication method is further provided, comprising the following steps:

[0846] Step 410: The terminal device receives first paging configuration information, where the first paging configuration information is used by the first terminal device to determine a first paging location.

[0847] Optionally, the terminal device may receive first paging configuration information sent by a base station. The base station here may be a serving base station of the terminal device, for example, the base station may be a source base station, a target base station, etc. of the terminal device, which is not limited in this embodiment of the present application.

[0848] Optionally, the first terminal device may be a terminal device that supports energy saving / NES, or the first terminal device may be a terminal device that supports a first protocol version, or the first terminal device may be a terminal device with at least one of a specific identifier, a specific service, and a specific group. The first protocol version may be Rel-18 or a later version of Rel-18.

[0849] In some embodiments, the wireless communication method provided in the embodiments of the present application further includes the following steps:

[0850] Step 420: The terminal device receives second paging configuration information, where the second paging configuration information is used by the second terminal device to determine a second paging location.

[0851] Optionally, the terminal device may receive second paging configuration information sent by the base station.

[0852] Optionally, the second terminal device may be a terminal device that does not support energy saving / NES, or the second terminal device may be a terminal device that does not support the first protocol version. In other words, the second terminal device may not be the first terminal device.

[0853] It should be noted that the base station may configure only the first paging configuration information for the first terminal device to perform paging configuration. In addition, the base station may also configure two paging configuration information: the first paging configuration information and the second paging configuration information, respectively for the first terminal device and the second terminal device to perform paging configuration. Steps 410 and 420 may be performed separately or simultaneously, and this embodiment of the application does not impose any restrictions on this.

[0854] It should be understood that the base station may configure the first paging configuration information for a terminal device that supports energy saving / NES, or a terminal device that supports the first protocol version, taking into account the network energy saving situation. It is understood that the first paging location configured by the first paging configuration information may not include the time domain location when the base station is performing energy saving / NES, or the base station is in an energy saving state / NES state, or the base station uses the energy saving / NES function, thereby reducing the monitoring locations of the paging message and achieving network energy saving.

[0855] The base station may configure second paging configuration information for the second terminal device, where the second paging configuration information may be determined based on an existing paging monitoring configuration and / or a defined monitoring mechanism.

[0856] Optionally, the first paging configuration information and / or the second paging configuration information may include one or more of the following:

[0857] Control resource set (controlResourceSet), search space (searchSpace), PO monitoring timing offset (firstPDCCH-MonitoringOccasionOfPO), synchronization signal block position (ssb-PositionsInBurst), default paging cycle (defaultPagingCycle), PF offset parameter (nAndPagingFrameOffset), and the number of POs included in PF (Ns).

[0858] In some embodiments, the first paging configuration information may further include one or more of the following:

[0859] The location of the paging monitoring window;

[0860] Continuous monitoring time period;

[0861] Non-monitoring time period;

[0862] The position of the paging monitoring window in the first cycle;

[0863] Continuous monitoring time period within the first cycle;

[0864] The non-monitoring period in the first cycle;

[0865] The first period includes a period related to the terminal device, or a period related to the cell, or a period related to the base station.

[0866] It should be noted that the continuous listening period and the non-listening period may include at least one of a start time, an end time, and a duration. The position of the paging listening window, the continuous listening period, and the non-listening period may be used in non-periodic scenarios. The position of the paging listening window within the first period, the continuous listening period within the first period, and the non-listening period within the first period may be used in periodic scenarios.

[0867] Optionally, the first cycle may be a paging DRX cycle, ie, a non-continuous monitoring cycle of the terminal device. Exemplarily, referring to FIG7 , the first paging configuration information may configure the position of the paging monitoring window, the continuous monitoring time period, and the non-monitoring time period within each DRX cycle.

[0868] Optionally, the first period may also be a cell-level or base station-level period allowed by the network. For example, as shown in FIG8 , the first paging configuration information may configure the position of the paging monitoring window, the continuous monitoring time period, and the non-monitoring time period within the cell-level or base station-level period.

[0869] It should be noted that the network allows the same cell-level or base station-level cycles for different terminal devices. For example, as shown in Figure 8 , UE1's paging DRX cycle is DRX Cycle 1, and UE2's paging DRX cycle is DRX Cycle 2. DRX Cycle 1 is different from DRX Cycle 2. UE1 and UE2 have the same cell-level or base station-level cycles.

[0870] In some embodiments, the second paging configuration information includes one or more of the following:

[0871] The location of the paging monitoring window;

[0872] Continuous monitoring time period;

[0873] Non-monitoring time period;

[0874] The position of the paging monitoring window in the second cycle;

[0875] Continuous monitoring time period in the second cycle;

[0876] The non-monitoring time period in the second cycle;

[0877] The second period includes a period related to the terminal device, or a period related to the cell, or a period related to the base station.

[0878] It should be noted that the description of the second paging configuration information can refer to the description of the first paging configuration information, and for the sake of brevity, it will not be repeated here.

[0879] In some embodiments, when the terminal device is a first terminal device, the terminal device may determine a first paging location based on the first paging configuration information and monitor paging messages at the first paging location. Correspondingly, the base station performs a paging operation on the first terminal device based on the first paging configuration information.

[0880] In some embodiments, when the terminal device is a first terminal device that meets the conditions, the terminal device can determine the first paging position based on the first paging configuration information, and listen for paging messages at the first paging position. Correspondingly, the base station performs a paging operation on the first terminal device based on the first paging configuration information. Optionally, when the terminal device is a first terminal device that does not meet the conditions, the terminal device can determine the second paging position based on the second paging configuration information, and listen for paging messages at the second paging position. Correspondingly, the base station performs a paging operation on the second terminal device based on the second paging configuration information. Optionally, the condition can be predefined, network configured / indicated, or terminal determined. Optionally, the condition that meets the conditions can be one of a specific identifier, a specific service, or a specific group, or the terminal that meets the specific conditions can be a UE of a specific identifier, a specific group, a characteristic service, etc.

[0881] It should be noted that when the network configures two paging configuration information, that is, when the network configures the first paging configuration information and the second paging configuration information for the terminal device at the same time, when the terminal device is a first terminal device, the terminal device can determine the first paging location based on the first paging configuration information and listen for paging messages at the first paging location. In addition, the terminal device can or may determine the second paging location based on the second paging configuration information and listen for paging messages at the second paging location, and this embodiment of the present application does not impose any restrictions on this.

[0882] Optionally, the first terminal device may determine the second paging location based on the second paging configuration information and listen for paging messages at the second paging location when certain conditions are met; optionally, the conditions may be predefined, configured / indicated by the network, or determined by the terminal device. For example, when the first paging configuration information is not received, or the first paging configuration information is unavailable, or the first paging location is unavailable, or there is no available first paging location within a certain period of time, or the terminal device is a specific first terminal device, etc., the first terminal device determines the second paging location based on the second paging configuration information and listens for paging messages at the second paging location.

[0883] Optionally, the first terminal device may also determine the second paging location according to the second paging configuration information without any conditional restrictions, and monitor the paging message at the second paging location.

[0884] Optionally, the base station pages the terminal device through paging DCI and paging message, or notifies the terminal device of system message changes or earthquake tsunami / public warning information through a short message.

[0885] In some embodiments, the terminal device monitors the paging message at the first paging location, including any one of the following:

[0886] The terminal device monitors the paging message at all or part of the first paging positions within the paging monitoring window;

[0887] The terminal device monitors the paging message at all or part of the first paging positions within the continuous monitoring time period; the continuous monitoring time period includes the time period during which the terminal device can monitor the paging message;

[0888] The terminal device monitors the paging message at all or part of the first paging positions within the paging monitoring window of each first cycle;

[0889] The terminal device monitors the paging message at all or part of the first paging positions within the continuous monitoring time period of each first cycle.

[0890] It is understandable that the terminal device monitors the paging message at all first paging positions within the paging monitoring window, or the continuous monitoring time period, or the paging monitoring window in each first cycle, or the continuous monitoring time period in each first cycle. The terminal device does not monitor outside the paging monitoring window, or the continuous monitoring time period, or the paging monitoring window in each first cycle, or the continuous monitoring time period in each first cycle.

[0891] In addition, the terminal device can monitor the paging message at part of the first paging positions within the paging monitoring window, or the continuous monitoring time period, or the paging monitoring window in each first cycle, or the continuous monitoring time period in each first cycle.

[0892] Optionally, part of the first paging locations is determined based on identification information of the terminal device and / or preset rules.

[0893] Exemplarily, the terminal device can take the modulus of the number of POs in the paging listening window or the continuous listening time period according to the terminal device's identifier (e.g., UE ID) to determine at which first paging position the terminal device performs monitoring in the paging listening window or the continuous listening time period.

[0894] In some embodiments, when the terminal device is a second terminal device, the terminal device is denied access to the base station;

[0895] Alternatively, when the terminal device is a second terminal device, the terminal device determines a second paging location based on the second paging configuration information, and monitors paging messages at the second paging location.

[0896] It should be understood that if the base station is only configured with the first paging configuration information, the base station blocks / rejects / does not allow the second terminal device to access.

[0897] If the base station is configured with the first paging configuration information and the second paging configuration information, the second terminal device can determine the second paging location based on the second paging configuration information and monitor the paging message at the second paging location. Correspondingly, the base station can perform a paging operation on the second terminal device based on the second paging configuration information.

[0898] In summary, the embodiments of the present application provide a paging enhancement method, which can configure different paging configuration information for different terminal devices. In particular, for terminal devices that support energy saving / NES, the special paging configuration information configured can reduce the listening position of paging messages and achieve network energy saving. It should be noted that the above-mentioned embodiment 6 can be implemented independently or in conjunction with other embodiments, and the embodiments of the present application do not limit this.

[0899] The following describes the method provided in the embodiments of the present application in conjunction with specific application scenarios.

[0900] Example 7

[0901] This embodiment provides a switching method based on NES, which includes the following steps.

[0902] Step 1: The network sends handover configuration information to the UE.

[0903] Step 1 may include at least one of the following 1.1-1.5:

[0904] 1.1. The network is the source base station.

[0905] 1.2. The UE is a UE that has established a connection with the source base station or has data transmission.

[0906] 1.3. The handover configuration information is information configured by RRC dedicated signaling.

[0907] 1.4. The handover configuration information is CHO-like configuration information. It is understandable that the handover configuration information includes handover configurations for multiple candidate target cells and conditions for performing handover using the handover configurations of the multiple candidate target cells.

[0908] Optionally, the conditions for executing handover configurations of multiple candidate target cells are common (such as for UE, or for the NES state of the source base station), or are cell-specific (such as each target candidate cell has its own configuration, and / or for the NES state of the target cell).

[0909] Optionally, the CHO-like configuration includes a handover configuration of a candidate target cell, wherein the handover configuration for the candidate target cell may be generated by the target base station.

[0910] Optionally, the CHO-like configuration includes an execution condition / evaluation condition, which may be generated by the target base station, or transmitted from the target base station to the source base station and then generated by the source base station.

[0911] Optionally, the condition for executing the handover configuration of multiple candidate target cells is a time condition, that is, at [A1, A1+delta1], the corresponding handover can be executed. (Otherwise, the handover of the handover configuration is not executed). Optionally, [A1, A1+delta1] is the time when the source base station is in NES or energy-saving state, or the time for executing the handover can be selected. Optionally, A1 is an absolute time, or a count number based on Greenwich time, or a relative time. Optionally, delta1 can be a duration, or a timer, or a duration. Optionally, the unit of Delta1 can be slo / symbol / Tc / subframe / frame / ms / 10ms, etc.

[0912] Optionally, the handover configuration execution condition of multiple candidate target cells is a time condition, that is, the corresponding handover can be performed between [A2, A2+delta2]. (Otherwise, the handover of the handover configuration is not performed outside [A2, A2+delta2]. Optionally, [A2, A2+delta2] is the time when the corresponding candidate target cell is in a non-NES or non-energy-saving state, or a time that can be selected for handover. Optionally, the time period available for handover (such as [A2, A2+delta2]) can be one or more.

[0913] Optionally, the handover configuration execution condition of multiple candidate target cells is a time condition, that is, the corresponding handover can be performed outside [A3, A3+delta3]. (Otherwise, the handover of the handover configuration is not performed between [A3, A3+delta3]. Optionally, [A3, A3+delta3] is the time when the corresponding candidate target cell is in NES or energy saving state, or the time when it cannot be selected for handover. Optionally, the time period available for handover (such as [A3, A3+delta3]) can be one or more.

[0914] Optionally, the handover configuration execution condition of the plurality of candidate target cells is a time condition, that is, whether the target cell is in, is about to be, has been, or is in the NES state at a certain time.

[0915] Optionally, the condition for executing handover configurations of multiple candidate target cells is indication information, i.e., whether network indication information triggering or executing handover of the handover configuration is received. For example, if received, the handover is executed. Otherwise, the handover is not executed. Alternatively, if received, the handover is executed within a certain time or under certain conditions (such as UE and network channel quality, RSRP, path loss, etc.), otherwise, the handover is not executed.

[0916] 1.5. The handover configuration information is CHO-like configuration information. The handover configuration information may include conditions for performing handover based on the source cell, conditions for performing CHO handover, or conditions for performing handover using handover configurations of multiple candidate target cells.

[0917] Optionally, the handover configurations of the multiple candidate target cells have a common handover condition (eg, for the UE, or for the NES state of the source base station).

[0918] Optionally, the CHO-like configuration information includes an execution condition / evaluation condition, and the execution condition / evaluation condition is generated by the source base station.

[0919] Optionally, the configuration information of CHO-lile includes one or more sets of execution conditions / evaluation conditions.

[0920] The CHO-lile configuration includes multiple sets of execution and evaluation conditions. For example, if the source base station is in NES or energy-saving state, a different set of evaluation conditions will be used (to ensure a faster handover to the target cell). If the source base station is in non-NES or non-energy-saving state, the existing set will be used, and handover to the target cell will occur if the existing evaluation and execution conditions are met.

[0921] Alternatively, the CHO-limit configuration information may include multiple sets of execution / evaluation conditions. For example, if the source base station is in an NES or energy-saving state and no cell meets the CHO execution conditions, a different set of evaluation conditions will be used (to expedite handover to the target cell). If the source base station is in a non-NES or non-energy-saving state, the existing set will be used, and handover to the target cell will occur if the existing evaluation execution conditions are met.

[0922] Alternatively, the CHO-lile configuration information includes a set of evaluation condition configurations. For example, when the source base station is in NES or energy-saving state, if no candidate target cell meets the CHO execution conditions, the best cell is selected as the target cell for handover based on the current measurement results after comparing several candidate cells.

[0923] Optionally, the condition for performing handover based on the situation of the source cell, or the condition for performing CHO handover, or the condition for performing handover using the handover configuration of multiple candidate target cells can be a time condition, that is, at [A4, A4+delta4], the UE can perform the corresponding handover. (Otherwise, the UE does not perform the corresponding handover). Optionally, the [A4, A4+delta4] is the time when the source base station is in NES or energy-saving state, or the time when CHO needs to be performed, or the time when CHO can be performed. Optionally, the time period that can be used for handover (such as [A4, A4+delta4]) can be one or more.

[0924] Optionally, under the above-mentioned time conditions, or under the NES or energy-saving state conditions of the source base station, the UE performs handover / CHO handover / uses a handover configuration of multiple candidate target cells according to a second set of execution conditions / evaluation conditions. The network configures multiple sets of execution conditions / evaluation conditions, the second set of execution conditions / evaluation conditions (including measurement events A3 / A5, etc., for the UE to judge the channel quality of the candidate cell, and / or, select or quickly select the target cell for handover), or the UE selects the candidate target cell with the best currently measured channel quality to perform handover.

[0925] Optionally, the conditions for performing switching based on the situation of the source cell, or the conditions for performing CHO switching, or the conditions for performing switching using the switching configuration of multiple candidate target cells may include status conditions, i.e., whether the source cell is, is about to be, has been, or is in NES state at a certain time.

[0926] Optionally, when the source base station is, is about to be, or is already in an NES or energy-saving state, the UE performs handover / CHO handover / uses a handover configuration of multiple candidate target cells according to a second execution condition / evaluation condition. The network configures multiple sets of execution conditions / evaluation conditions, a second set of execution conditions / evaluation conditions (including measurement events A3 / A5, etc., for the UE to determine the channel quality of the candidate cell, and / or, to select or quickly select the target cell for handover), or the UE selects the candidate target cell with the best currently measured channel quality to perform handover.

[0927] Optionally, the conditions for performing handover based on the situation of the source cell, or the conditions for performing CHO handover, or the conditions for performing handover using a handover configuration of multiple candidate target cells may include a state condition, i.e., indication information, i.e., whether network indication information for triggering or executing the handover of the handover configuration is received. For example, if received, the handover is executed. Otherwise, the handover is not executed. Alternatively, if received, the handover is executed within a certain time or under certain conditions (such as UE and network channel quality, RSRP, path loss, etc.), otherwise, the handover is not executed.

[0928] Optionally, the indication information may be NES or energy-saving information of the source base station.

[0929] Optionally, the instruction information is display instruction information that triggers execution.

[0930] Step 2: The UE saves the handover configuration information sent by the network and performs a handover (CHO-like handover) corresponding to the handover configuration information when conditions are met.

[0931] Wherein, step 2 may include at least one of the following 2.1-2.6.

[0932] 2.1. The UE saves the handover configuration information configured by the network, but does not perform the handover corresponding to the handover configuration information. In addition, when the conditions are met, the UE performs the handover corresponding to the handover configuration information (CHO-like handover).

[0933] 2.2. The UE saves the handover configuration information configured by the network and performs measurements based on the configuration information. Alternatively, it starts performing measurements upon receipt of the handover configuration information. For example, if a CHO-like configuration is received, the UE performs measurements immediately without waiting for the NES transition.

[0934] 2.3. When the UE meets the conditions, perform the handover corresponding to the handover configuration information (CHO-like handover). Specifically, when the source cell meets the first condition, and / or the target cell meets the second condition, and / or the UE meets the third condition, and / or the fourth condition, perform CHO, or perform the handover corresponding to the handover configuration information (CHO-like handover).

[0935] Optionally, the first condition includes at least one of the following: the source cell is an NES cell, the source cell is in the NES state, the source cell changes state (from non-NES to NES), the NES state duration of the source cell is greater than or equal to the first duration (configured together with the CHO configuration, or configured independently, or configured after the source cell state is switched after CHO), the channel quality of the source cell is less than or equal to the first threshold (for example, an implicit energy saving situation, or an existing CHO execution condition), the difference between the channel quality of the target cell and the channel quality of the source cell is greater than a second threshold, and CHO is triggered within the NES or energy saving time [T1, T2] of the source cell (for example, [T1, T2] can be [A1, A1+delta1], or [A4, A4+delta4]. Optionally, the NES or energy saving time information of the source cell is indicated in the CHO-like switching configuration, or is separately indicated by the network outside the CHO-like switching configuration.

[0936] Optionally, the second condition includes at least one of the following: the target cell is not an NES cell or is not in the NES state, the channel quality of the target cell is greater than or equal to a third threshold, the difference between the channel quality of the target cell and the channel quality of the source cell is greater than or equal to the second threshold, the duration for which the channel quality of the target cell is greater than or equal to the third threshold is greater than the first duration, the target cell meets the existing CHO execution conditions (A3 / 5, etc.) and is in the non-NES state, within the time [A2, A2+delta2] corresponding to the target cell, and outside the time [A3, A3+delta3] corresponding to the target cell.

[0937] Optionally, the third condition includes at least one of the following: the UE's serving cell is the source cell, the UE is a NES-capable UE, the UE has no transmission requirement within the first time period, the UE receives switching configuration for multiple cells, and the UE has RLF in the NES case of the source cell.

[0938] Optionally, the fourth condition includes at least one of the following: the network (source cell) sends indication information 1, or the UE receives indication information 1. Indication information 1 is used to instruct the UE to perform CHO, or indicate NES information of the source cell / target cell, or instruct a UE that meets the conditions (NES-capable UE) to perform handover or trigger the UE to perform CHO.

[0939] 2.4. When the conditions are met, the UE executes the handover corresponding to the handover configuration information (CHO-like handover). The conditions can be used together with the existing CHO execution conditions / CHO evaluation conditions (trigger conditions), or they can be decoupled. That is, the execution conditions / evaluation conditions configured in the handover configuration information and the CHO execution conditions / CHO evaluation conditions are used separately. That is, the CHO-like handover has its own unique execution conditions.

[0940] 2.5. The UE selects a candidate target cell that meets the channel quality conditions as the final handover cell, or the UE preferentially selects a cell that meets the channel quality conditions and is not NES as the handover target cell, or the UE preferentially selects a cell that is not NES as the handover target cell, or the UE preferentially selects a cell whose NES time is shorter than the sixth duration as the handover target cell, or the UE preferentially selects a cell whose channel quality meets the conditions and whose NES time is shorter than the sixth duration as the handover target cell.

[0941] 2.6. Before executing CHO, or before any CHO execution condition is met, if an HO command (without CHO-like configuration) is received, the UE performs the HO procedure, ignores, disregards, or deletes the received CHO-like configuration, and / or terminates the CHO execution.

[0942] In summary, this embodiment provides a cell handover method when the source base station is in the NES state or changes to the NES state. This embodiment can be implemented in combination with other embodiments or can be implemented alone.

[0943] Example 8

[0944] This embodiment provides a method for selecting a target cell for handover based on handover configuration information, including the following steps.

[0945] Step 1: The network sends handover configuration information to the UE.

[0946] Step 1 may include at least one of the following 1.1-1.5:

[0947] 1.1. The network is the source base station.

[0948] 1.2. The UE is a UE that has established a connection with the source base station or has data transmission.

[0949] 1.3. The handover configuration information is information configured by RRC dedicated signaling.

[0950] 1.4. The handover configuration information is CHO-like configuration information. It is understandable that the handover configuration information includes handover configurations for multiple candidate target cells and conditions for performing handover using the handover configurations of the multiple candidate target cells.

[0951] Optionally, the conditions for executing handover configurations of multiple candidate target cells are common (such as for UE, or for the NES state of the source base station), or are cell-specific (such as each target candidate cell has its own configuration, and / or for the NES state of the target cell).

[0952] Optionally, the CHO-like configuration includes a handover configuration of a candidate target cell, wherein the handover configuration for the candidate target cell may be generated by the target base station.

[0953] Optionally, the CHO-like configuration includes an execution condition / evaluation condition, which may be generated by the target base station, or transmitted from the target base station to the source base station and then generated by the source base station.

[0954] Optionally, the condition for executing the handover configuration of multiple candidate target cells is a time condition, that is, at [A1, A1+delta1], the corresponding handover can be executed. (Otherwise, the handover of the handover configuration is not executed). Optionally, [A1, A1+delta1] is the time when the source base station is in NES or energy-saving state, or the time for executing the handover can be selected. Optionally, A1 is an absolute time, or a count number based on Greenwich time, or a relative time. Optionally, delta1 can be a duration, or a timer, or a duration. Optionally, the unit of Delta1 can be slo / symbol / Tc / subframe / frame / ms / 10ms, etc.

[0955] Optionally, the handover configuration execution condition of multiple candidate target cells is a time condition, that is, the corresponding handover can be performed between [A2, A2+delta2]. (Otherwise, the handover of the handover configuration is not performed outside [A2, A2+delta2]. Optionally, [A2, A2+delta2] is the time when the corresponding candidate target cell is in a non-NES or non-energy-saving state, or a time that can be selected for handover. Optionally, the time period available for handover (such as [A2, A2+delta2]) can be one or more.

[0956] Optionally, the handover configuration execution condition of multiple candidate target cells is a time condition, that is, the corresponding handover can be performed outside [A3, A3+delta3]. (Otherwise, the handover of the handover configuration is not performed between [A3, A3+delta3]. Optionally, [A3, A3+delta3] is the time when the corresponding candidate target cell is in NES or energy saving state, or the time when it cannot be selected for handover. Optionally, the time period available for handover (such as [A3, A3+delta3]) can be one or more.

[0957] Optionally, the handover configuration execution condition of the plurality of candidate target cells is a time condition, that is, whether the target cell is in, is about to be, has been, or is in the NES state at a certain time.

[0958] Optionally, the condition for executing handover configurations of multiple candidate target cells is indication information, i.e., whether network indication information triggering or executing handover of the handover configuration is received. For example, if received, the handover is executed. Otherwise, the handover is not executed. Alternatively, if received, the handover is executed within a certain time or under certain conditions (such as UE and network channel quality, RSRP, path loss, etc.), otherwise, the handover is not executed.

[0959] 1.5. The handover configuration information is CHO-like configuration information. The handover configuration information may include conditions for performing handover based on the source cell, conditions for performing CHO handover, or conditions for performing handover using handover configurations of multiple candidate target cells.

[0960] Optionally, the handover configurations of the multiple candidate target cells have a common handover condition (eg, for the UE, or for the NES state of the source base station).

[0961] Optionally, the CHO-like configuration information includes an execution condition / evaluation condition, and the execution condition / evaluation condition is generated by the source base station.

[0962] Optionally, the configuration information of CHO-lile includes one or more sets of execution conditions / evaluation conditions.

[0963] The CHO-lile configuration includes multiple sets of execution and evaluation conditions. For example, if the source base station is in NES or energy-saving state, a different set of evaluation conditions will be used (to facilitate handover to the target cell). If the source base station is in non-NES or non-energy-saving state, the existing set will be used, and handover to the target cell will occur if the existing evaluation and execution conditions are met.

[0964] Alternatively, the CHO-limit configuration information may include multiple sets of execution / evaluation conditions. For example, if the source base station is in an NES or energy-saving state and no cell meets the CHO execution conditions, a different set of evaluation conditions will be used (to expedite handover to the target cell). If the source base station is in a non-NES or non-energy-saving state, the existing set will be used, and handover to the target cell will occur if the existing evaluation execution conditions are met.

[0965] Alternatively, the CHO-lile configuration information includes a set of evaluation condition configurations. For example, when the source base station is in NES or energy-saving state, if no candidate target cell meets the CHO execution conditions, the best cell is selected as the target cell for handover based on the current measurement results after comparing several candidate cells.

[0966] Optionally, the condition for performing handover based on the situation of the source cell, or the condition for performing CHO handover, or the condition for performing handover using the handover configuration of multiple candidate target cells can be a time condition, that is, at [A4, A4+delta4], the UE can perform the corresponding handover. (Otherwise, the UE does not perform the corresponding handover). Optionally, the [A4, A4+delta4] is the time when the source base station is in NES or energy-saving state, or the time when CHO needs to be performed, or the time when CHO can be performed. Optionally, the time period that can be used for handover (such as [A4, A4+delta4]) can be one or more.

[0967] Optionally, under the above-mentioned time conditions, or under the NES or energy-saving state conditions of the source base station, the UE performs handover / CHO handover / uses a handover configuration of multiple candidate target cells according to a second set of execution conditions / evaluation conditions. The network configures multiple sets of execution conditions / evaluation conditions, the second set of execution conditions / evaluation conditions (including measurement events A3 / A5, etc., for the UE to judge the channel quality of the candidate cell, and / or, select or quickly select the target cell for handover), or the UE selects the candidate target cell with the best currently measured channel quality to perform handover.

[0968] Optionally, the conditions for performing switching based on the situation of the source cell, or the conditions for performing CHO switching, or the conditions for performing switching using the switching configuration of multiple candidate target cells may include status conditions, i.e., whether the source cell is, is about to be, has been, or is in NES state at a certain time.

[0969] Optionally, when the source base station is, is about to be, or is already in an NES or energy-saving state, the UE performs handover / CHO handover / uses a handover configuration of multiple candidate target cells according to a second execution condition / evaluation condition. The network configures multiple sets of execution conditions / evaluation conditions, a second set of execution conditions / evaluation conditions (including measurement events A3 / A5, etc., for the UE to determine the channel quality of the candidate cell, and / or, to select or quickly select the target cell for handover), or the UE selects the candidate target cell with the best currently measured channel quality to perform handover.

[0970] Optionally, the conditions for performing handover based on the situation of the source cell, or the conditions for performing CHO handover, or the conditions for performing handover using a handover configuration of multiple candidate target cells may include a state condition, i.e., indication information, i.e., whether network indication information for triggering or executing the handover of the handover configuration is received. For example, if received, the handover is executed. Otherwise, the handover is not executed. Alternatively, if received, the handover is executed within a certain time or under certain conditions (such as UE and network channel quality, RSRP, path loss, etc.), otherwise, the handover is not executed.

[0971] Optionally, the indication information may be NES or energy-saving information of the source base station.

[0972] Optionally, the instruction information is display instruction information that triggers execution.

[0973] Step 2: The UE saves the handover configuration information sent by the network. The UE performs a handover corresponding to the handover configuration (CHO-like handover) and selects a target cell for the handover.

[0974] A candidate target cell is selected as a handover target cell when it meets at least one of the following conditions: the target cell is an NES cell, there are multiple target cells meeting the conditions (for example, when multiple target cells meet the conditions, non-NES cells or cells with higher priority may be selected first), the target cell is currently in or not in the NES state, and the target cell is the cell that will be switched to the NES state. The time interval between the current moment and the moment when the target cell is about to switch to the NES state is less than the fourth duration, the target cell is a cell that will switch to the non-NES state, the duration between the current moment and the moment when the target cell is about to switch to the non-NES state is less than the fifth duration, the target cell is a cell that is in the NES state for less than the sixth duration, the target cell is a cell whose channel quality meets the channel quality condition (for example, meets one of A3 / 4 / 5, etc.), the target cell is a cell whose channel quality is greater than or equal to the sixth threshold, the target cell is a cell whose channel quality is greater than or equal to the channel quality of the NES target cell, the target cell is a cell whose channel quality difference with the channel quality of the NES target cell is less than or equal to the seventh threshold, the target cell is a cell whose channel quality difference with the channel quality of the NES target cell is less than or equal to the seventh threshold for a duration greater than the seventh duration, the target cell is a priority cell, the target cell is a non-low priority cell, the target cell is a priority cell, and the target cell is the cell with the highest priority.

[0975] Optionally, the above-mentioned priority or priority order may be indicated by the network. For example, the network may indicate the priority of the candidate target cells separately or in the CHO configuration. Alternatively, the network may indicate the priority order of the candidate target cells separately or in the CHO configuration. Alternatively, the network may indicate whether cells in the NES state are given low priority or in the CHO configuration. Alternatively, the network may indicate which cells in the NES state are given low priority or in the CHO configuration.

[0976] Optionally, how to operate based on priority / low priority order, or whether to select the target cell based on priority / priority order, can be used in the following situations: when there are multiple cells that meet the conditions (such as channel quality conditions, or channel quality rank values), or when there are multiple cells that meet the conditions (such as channel quality conditions, or channel quality rank values) and the channel quality difference / rank difference of the multiple cells is within a range, or when the channel quality difference / channel quality rank value difference of the cells with the best channel quality is within a range.

[0977] Optionally, before executing CHO, or before any CHO execution condition is met, an HO command (without CHO-like configuration) is received, the UE performs the HO process, ignores or does not consider or deletes the received CHO-like configuration, and / or terminates the CHO execution.

[0978] In summary, in this embodiment, the terminal device can select a suitable handover cell based on CHO or CHO-like handover. This embodiment can be used in combination with other embodiments or can be used alone.

Optionally, the time period available for handover (such as [A3, A3+delta3]) can be one or more.

[0993] Optionally, the handover configuration execution condition of the plurality of candidate target cells is a time condition, that is, whether the target cell is in, is about to be, has been, or is in the NES state at a certain time.

For example, if received, the handover is executed. Otherwise, the handover is not executed. Alternatively, if received, the handover is executed within a certain time or under certain conditions (such as UE and network channel quality, RSRP, path loss, etc.), otherwise, the handover is not executed.

[0995] 1.5. The handover configuration information is CHO-like configuration information. The handover configuration information may include conditions for performing handover based on the source cell, conditions for performing CHO handover, or conditions for performing handover using handover configurations of multiple candidate target cells.

[0996] Optionally, the handover configurations of the multiple candidate target cells have a common handover condition (eg, for the UE, or for the NES state of the source base station).

[0998] Optionally, the configuration information of CHO-lile includes one or more sets of execution conditions / evaluation conditions.

[0999] The CHO-lile configuration includes multiple sets of execution and evaluation conditions. For example, if the source base station is in NES or energy-saving state, a different set of evaluation conditions will be used (to facilitate handover to the target cell). If the source base station is in non-NES or non-energy-saving state, the existing set will be used, and handover to the target cell will occur if the existing evaluation and execution conditions are met.

[1000] Alternatively, the CHO-limit configuration information may include multiple sets of execution / evaluation conditions. For example, if the source base station is in an NES or energy-saving state and no cell meets the CHO execution conditions, a different set of evaluation conditions will be used (to expedite handover to the target cell). If the source base station is in a non-NES or non-energy-saving state, the existing set will be used, and handover to the target cell will occur if the existing evaluation execution conditions are met.

[1001] Alternatively, the CHO-lile configuration information includes a set of evaluation condition configurations. For example, when the source base station is in NES or energy-saving state, if no candidate target cell meets the CHO execution conditions, the best cell is selected as the target cell for handover based on the current measurement results after comparing several candidate cells.

[1002] Optionally, the condition for performing handover based on the situation of the source cell, or the condition for performing CHO handover, or the condition for performing handover using the handover configuration of multiple candidate target cells can be a time condition, that is, at [A4, A4+delta4], the UE can perform the corresponding handover. (Otherwise, the UE does not perform the corresponding handover). Optionally, the [A4, A4+delta4] is the time when the source base station is in NES or energy-saving state, or the time when CHO needs to be performed, or the time when CHO can be performed. Optionally, the time period that can be used for handover (such as [A4, A4+delta4]) can be one or more.

[1003] Optionally, under the above-mentioned time conditions, or under the NES or energy-saving state conditions of the source base station, the UE performs handover / CHO handover / uses a handover configuration of multiple candidate target cells according to a second set of execution conditions / evaluation conditions. The network configures multiple sets of execution conditions / evaluation conditions, the second set of execution conditions / evaluation conditions (including measurement events A3 / A5, etc., for the UE to judge the channel quality of the candidate cell, and / or, select or quickly select the target cell for handover), or the UE selects the candidate target cell with the best currently measured channel quality to perform handover.

[1004] Optionally, the conditions for performing switching based on the situation of the source cell, or the conditions for performing CHO switching, or the conditions for performing switching using the switching configuration of multiple candidate target cells may include status conditions, i.e., whether the source cell is, is about to be, has been, or is in NES state at a certain time.

[1005] Optionally, when the source base station is, is about to be, or is already in an NES or energy-saving state, the UE performs handover / CHO handover / uses a handover configuration of multiple candidate target cells according to a second execution condition / evaluation condition.

[1006] Optionally, the conditions for performing handover based on the situation of the source cell, or the conditions for performing CHO handover, or the conditions for performing handover using a handover configuration of multiple candidate target cells may include a state condition, i.e., indication information, i.e., whether network indication information for triggering or executing the handover of the handover configuration is received. For example, if received, the handover is executed. Otherwise, the handover is not executed. Alternatively, if received, the handover is executed within a certain time or under certain conditions (such as UE and network channel quality, RSRP, path loss, etc.), otherwise, the handover is not executed.

[1007] Optionally, the indication information may be NES or energy-saving information of the source base station.

[1008] Optionally, the instruction information is display instruction information that triggers execution.

[1009] Step 2: The UE saves the handover configuration information sent by the network. If the UE satisfies at least one of the following conditions, the UE does not perform the handover corresponding to the handover configuration (CHO-like handover), or terminates the CHO.

[1010] Specifically, when the source cell satisfies the fifth condition, and / or the target cell satisfies the sixth condition, and / or the UE satisfies the seventh condition, and / or the eighth condition, the UE is prevented from performing handover, CHO or not performing CHO.

[1011] Optionally, the fifth condition includes at least one of the following: the source cell is an NES cell, the source cell is in a non-NES state or is temporarily suspended from entering the NES state or is about to leave the NES state, the NES state duration of the source cell is less than or equal to the first duration, the channel quality of the source cell is greater than or equal to a fourth threshold, and the source cell is within the duration of NES or energy saving or inability to execute CHO.

[1014] Optionally, the eighth condition includes at least one of the following: the network (source cell) sends indication information 2, or the UE receives indication information 2. Indication information 2 is used to instruct the UE not to perform CHO, or to prevent the UE from performing CHO, or to indicate NES information of the source / target cell, or to instruct the UE that meets the conditions to suspend or not perform handover or trigger the UE to perform CHO); the UE does not receive indication information 1 in embodiment 7.

[1015] Optionally, for step 2, before step 2, the UE may receive handover configurations for multiple candidate target cells.

[1016] Optionally, for step 2, the UE saves the handover configuration information configured by the network, but does not perform the handover corresponding to the handover configuration information. Furthermore, when the UE meets the conditions, it performs the handover corresponding to the handover configuration information (CHO-like handover).

[1017] Optionally, for step 2, the UE saves the handover configuration information configured by the network and performs measurements based on the configuration information. Alternatively, the UE starts performing measurements upon receipt of the handover configuration information. For example, if a CHO-like configuration is received, the UE immediately performs measurements without waiting for NES transition.

[1018] In summary, in this embodiment, the terminal device can exit / terminate cell switching according to conditions, thereby avoiding the problem of ping-pong switching of the terminal device and improving communication performance. It should be noted that this embodiment can be implemented alone or in combination with other embodiments.

[1019] Example 10

[1020] This embodiment provides a method for avoiding group handover indication failure, or a method for improving a group handover success rate, or a method for avoiding group CHO execution failure, including the following steps.

[1021] Step 1: The network sends handover configuration information to the UE.

[1022] Step 1 may include at least one of the following 1.1-1.7:

[1023] 1.1. The network is the source base station.

[1024] 1.2. The UE is a UE that has established a connection with the source base station or has data transmission.

[1025] 1.3. The handover configuration information is information configured by RRC dedicated signaling.

[1026] 1.4. The switching configuration information includes the area configuration information.

[1027] Optionally, the area configuration information is common (eg, for UE, or for source base station).

[1028] Optionally, the area configuration information is generated by a source base station.

[1029] Optionally, the area configuration information may include indication information of one or more areas.

[1030] Optionally, the area configuration information may be related to the channel quality / path loss / distance between the UE and the base station (for example, in the center or edge of the cell, in the middle or edge or center of the cell, etc.), or may be related to the orientation of the UE at the base station (for example, which beam direction, east, west, south, etc.).

[1031] Optionally, different groups and / or DCI / RNTI corresponding to the groups are allocated and indicated to the UE according to the area configuration information.

[1032] For example, group signaling (such as group DCI, group MAC CE, etc.) can be used to trigger handover / CHO handover in the cell center area, and UE-specific messages or group signaling + UE-specific messages can be used to trigger handover / CHO handover in the cell edge area. Alternatively, group signaling (such as group DCI, group MAC CE, etc.) can be used to trigger handover / CHO handover in the direction of cell beam 1 or the east direction of the UE, and UE-specific messages or group signaling + UE-specific messages can be used to trigger handover / CHO handover in other areas.

[1033] 1.5. The switching configuration information includes information on the number of repeated transmissions.

[1034] Optionally, the repetition transmission number information is common (eg, for UE, or for source base station), or may be for UEs in different areas, wherein UEs in different areas have different repetition transmission number information.

[1035] Optionally, the number of repeated transmission times information includes one or more.

[1036] Optionally, the information on the number of repeated transmissions may be related to different areas, or may be unrelated to different areas (common to all areas).

[1037] Optionally, the repeated transmission number information is generated by a source base station.

[1038] Optionally, different groups and / or DCI / RNTI corresponding to the groups are allocated and indicated to the UE according to the number of repeated transmissions.

[1039] For example, group signaling (e.g., group DCI, group MAC CE, etc.) can be used to trigger handover / CHO handover in the cell center area, and the group signaling is not repeatedly sent or the number of repeated transmissions is N1. Group signaling (e.g., group DCI, group MAC CE, etc.) can be used to trigger handover / CHO handover in the cell edge area, and the group signaling is not repeatedly sent or the number of repeated transmissions is N2. Where N1 is less than N2.

[1040] For example, in the center area of ​​the cell, group signaling can be used to trigger handover / CHO handover (such as group DCI, group MAC CE, etc.), and the group signaling is not sent repeatedly or the number of repeated transmissions is N3. In the middle area of ​​the cell, group signaling can be used to trigger handover / CHO handover (such as group DCI, group MAC CE, etc.), and the number of repeated transmissions of group signaling is N4. In the edge area of ​​the cell, group signaling can be used to trigger handover / CHO handover (such as group DCI, group MAC CE, etc.), and the number of repeated transmissions of group signaling is N5, where N3 <N4<N5。

[1041] For example, within the entire cell range, cell-specific signaling is used for all UEs under the cell, or group signaling for different UE groups is used to trigger handover / CHO handover (such as group DCI, group MAC CE, etc.), and the number of repeated group signaling transmissions is N6, and N6 is greater than or equal to 1.

[1042] 1.6. The handover configuration information is CHO-like configuration information. It is understandable that the handover configuration information includes handover configurations for multiple candidate target cells and conditions for performing handover using the handover configurations of the multiple candidate target cells.

[1043] 1.7. The handover configuration information is CHO-like configuration information. The handover configuration information may include conditions for performing handover based on the source cell, conditions for performing CHO handover, or conditions for performing handover using handover configurations of multiple candidate target cells.

[1044] Step 2. The UE saves the handover configuration information configured by the network. Upon receiving a network-triggered handover command, the UE performs handover corresponding to the handover configuration (CHO-like handover). The handover command / CHO handover command sent by the network may be UE-specific signaling (such as a dedicated RRC) or group signaling (such as a group DCI, group MAC CE, group RRC, etc.). Optionally, the cell handover command / CHO handover command sent by the network includes at least one of the following 2.1-2.4.

[1045] 2.1. The source base station sends a handover command / CHO handover command N times within a period of time, or repeatedly sends a handover command / CHO handover command N times.

[1046] Optionally, the signal is sent repeatedly N times within the cell range.

[1047] Optionally, the UE may determine how many times it needs to receive the network-triggered handover command / CHO handover command based on RSRP, beam direction with the network, position of the UE in the network, path loss, distance with the network, and the like.

[1048] Optionally, when the UE receives the handover command / CHO handover command triggered by the network once, it may ignore or not receive the subsequently repeatedly sent handover command / CHO handover command.

[1049] Optionally, upon receiving the handover command / CHO handover command triggered by the network once, the UE starts to execute the handover / CHO.

[1050] 2.2. The source base station uses group signaling to send a handover command / CHO handover command within a certain range, and uses a dedicated message to send a handover command / CHO handover command within other ranges.

[1051] Optionally, the certain range may be determined, for example, based on channel quality, location, path loss, or beam direction, or based on orientation (e.g., east, west, south, or north). For example, when the channel quality is greater than threshold 1, a handover command / CHO handover command is sent using group signaling. Otherwise, a dedicated message may be used to trigger the handover command / CHO handover command.

[1052] Optionally, the range may be determined based on the number of UEs. For example, if the number of UEs in the cell is greater than a threshold of 1, a handover command / CHO handover command may be ...
