Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a conditional reconfiguration method, device, apparatus, and storage medium. Background Art

[0002] The current 3GPP (3rd Generation Partnership Project) protocol only supports the network-side configuration of CHO (Condition Handover) or CPAC (Conditional PSCell (Primary Secondary Cell) Addition / Change) for UEs (User Equipment). This means that when CHO is configured, the UE only determines whether the conditions for handover of the PCell (Primary Cell) are met and thus only performs the PCell handover process, i.e., the PCell handover process is not accompanied by the addition or change of a PSCell (Primary Secondary Cell). Alternatively, when CPAC is configured, only the conditions for PSCell addition or change are determined and thus only performs the PSCell addition or change process, i.e., the PSCell addition or change process is not accompanied by a PCell handover process. This results in the UE only being able to perform PCell handover or PSCell addition or change, resulting in degraded network performance. Summary of the Invention

[0096] In a conditional PCell handover scenario with PSCell addition or change, configuring only the cell-level execution conditions, taking the PCell as an example, will result in that when the PCell execution conditions are met, the UE still cannot determine the appropriate PSCell for PSCell addition or change. This will result in the UE only being able to perform PCell handover, or the PSCell the UE accesses is not the optimal PSCell or fails, resulting in network performance degradation. Similarly, when the PSCell execution conditions are met first, the UE still cannot determine the appropriate PCell for handover. This will result in the UE only being able to perform PSCell addition or change, or the PCell the UE accesses is not the optimal PCell or directly leads to access failure.

[0097] In the embodiments of this application, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0098] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0099] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0100] In order to facilitate a clearer understanding of the various embodiments of the present application, some relevant background knowledge is first introduced as follows.

[0101] (1) The main idea of ​​CHO / CPAC switching

[0102] To improve the robustness and reliability of mobility, 3GPP R16 introduced conditional switching and PSCell condition change within an SN (Secondary Node) without the participation of an MN (Master Node). 3GPP R17 introduced PSCell condition change between SNs and conditional PSCell addition.

[0103] Whether it is CHO, PSCell condition change within an SN, conditional PSCell condition change between SNs, or conditional PSCell addition, the main idea is that the network side pre-configures multiple target cells for the UE, that is, the configuration information and execution conditions of the target cells are sent to the UE in advance. When the UE receives the configuration information of the target cell, it will not immediately perform the handover or PSCell change or PSCell addition as in traditional handover, PSCellchange or PSCelladdition. Instead, it will save the received configuration and perform measurement and evaluation on the configured alternative cells until a cell that meets the execution conditions is found. The UE will then execute the stored reconfiguration message corresponding to the cell and perform the corresponding handover or PSCell change or PSCelladdition process, that is, complete downlink synchronization and trigger the random access process to access the target PCell or PSCell.

[0104] R16 only supports the network side configuring CHO or CPAC for the UE separately, that is, when configuring CHO, the UE only determines whether the PCell switching conditions are met and thus only executes the PCell switching process, that is, the PCell switching process is not accompanied by PSCell addition or change, or when CPAC is configured, it only determines whether the execution conditions of PSCell addition or change are met, and thus only executes the PSCell addition or change process, that is, the PSCell addition or change process is not accompanied by the PCell switching process.

[0105] (2) Multi-beam

[0106] The NR (New Radio) system supports multiple beams. Different beams can be identified by the SSB (Synchronization Signal Block) index. The UE can also adjust the beam by measuring the CSI-RS (Channel State Information-Reference Signal) signal. The network can determine the serving beam by measuring the reference signal strength.

[0107] R17 or R18 is expected to introduce research on the coexistence scenarios of CHO and MRDC (Multi-RAT (Radio Access Technology) Dual Connectivity). Compared with the CHO scenario, adding or changing the PSCell while performing conditional PCell switching can establish MRDC while performing PCell switching, which can reduce the latency of establishing MRDC and help improve network throughput, or complete PSCell mobility management while maintaining PCell connection.

[0108] In addition, according to the current research conclusions of CHO, the network side can only configure cell-level execution conditions for the UE. However, in the PCell switching scenario with conditional PSCell addition or change, if only the cell-level execution conditions are configured, when the PCell execution conditions are met, the UE still cannot determine whether the PSCell addition or change is met. This will cause the UE to only be able to perform PCell switching, or the PSCell accessed by the UE is not the optimal PSCell or the switching fails, resulting in a decrease in network performance. The same problem also exists when the PSCell execution conditions are met first, the UE still cannot determine the appropriate PCell for switching, which will cause the UE to only be able to perform PSCell addition or change, or the PCell accessed by the UE is not the optimal PCell or directly lead to access failure.

[0109] In a conditional PCell handover scenario with PSCell addition or change, configuring only the cell-level execution conditions, taking the PCell as an example, will result in that when the PCell execution conditions are met, the UE still cannot determine the appropriate PSCell for PSCell addition or change. This will result in the UE only being able to perform PCell handover, or the PSCell the UE accesses is not the optimal PSCell or fails, resulting in network performance degradation. Similarly, when the PSCell execution conditions are met first, the UE still cannot determine the appropriate PCell for handover. This will result in the UE only being able to perform PSCell addition or change, or the PCell the UE accesses is not the optimal PCell or directly leads to access failure.

[0110] In response to the above problems, each embodiment of the present application provides a solution, the core idea of ​​which is: for the conditional PCell switching scenario with PSCell addition or change, an execution condition related to beam information is introduced, that is, the network side can additionally configure the corresponding execution condition related to beam information for the candidate target PCell cell. When the cell-level execution condition of a certain PCell is met, the UE can further select the best PSCell from the candidate PSCell cells associated with the PCell based on the execution condition related to the beam information, and simultaneously initiate access to the PCell cell and the PSCell cell. This solution is also applicable to the case where the measurement target is PSCell, and cell-level execution conditions and additional execution conditions related to beam information are configured for the candidate target PSCell. When determining the addition or change of PSCell, the appropriate PCell access is selected based on the beam information, thereby improving the success rate and reliability of the switching.

[0111] It should be noted that, for the convenience of subsequent discussion, the various embodiments of the present application are mainly described using the measurement target cell as PCell as an example. Of course, those skilled in the art can know that the technical solutions of the various embodiments of the present application are not limited to the scenario where the measurement target cell is PCell, and can also be applied to the scenario where the measurement target cell is PSCell.

[0112] In each embodiment of the present application, the measurement target cell is PCell or PSCell; the associated target cell is: for the scenario where the measurement target cell is PCell, the associated target cell is PSCell; for the scenario where the measurement target cell is PSCell, the associated target cell is Pcell.

[0113] For the scenario where the target cell to be measured is a PCell, the target measurement node is the target MN; for the scenario where the target cell to be measured is a PSCell, the target measurement node is the target SN.

[0114] Figure 1 A flow chart of a conditional reconfiguration method provided in an embodiment of the present application, which is applied to a network node (eg, a base station), such as Figure 1 As shown, the method includes the following steps:

[0115] Step 100: Start;

[0116] Step 101. Send a reconfiguration message containing one or more conditional reconfiguration configuration information and auxiliary information for determining the beam to the user terminal; wherein the conditional reconfiguration configuration information at least includes configuration information of the measurement target cell, configuration information of the associated target cell, cell-level execution conditions of the measurement target cell, and execution conditions related to the beam information.

[0117] Specifically, in the embodiment of the present application, the network node may be a source master node MN. The measurement target cell may be a PCell or a PSCell. For scenarios where the measurement target cell is a PCell, the associated target cell is a PSCell. For scenarios where the measurement target cell is a PSCell, the associated target cell is a PCell.

[0118] To enable the user terminal to select a suitable candidate target PCell and its associated candidate target PSCell, or to enable the user terminal to select a suitable candidate target PSCell and its associated candidate target PCell, the network node may send a reconfiguration message containing one or more conditional reconfiguration configuration information and auxiliary information for beam determination to the user terminal. The conditional reconfiguration configuration information includes at least configuration information of the measurement target cell, configuration information of the associated target cell, cell-level execution conditions of the measurement target cell, and execution conditions related to beam information.

[0119] After receiving the above-mentioned reconfiguration message and the auxiliary information used to determine the beam, the user terminal can perform measurement evaluation on the candidate measurement target cell based on the cell-level execution condition of the measurement target cell. When the measurement evaluation finds that the cell-level execution condition of a candidate measurement target cell is met, the user terminal can determine that the candidate measurement target cell is the access measurement target cell.

[0120] After determining the access measurement target cell, the user terminal can determine the associated target cell corresponding to the access measurement target cell based on the execution conditions related to the beam information and the auxiliary information used to determine the beam, and access the determined access measurement target cell and the determined associated target cell.

[0121] Optionally, the auxiliary information for determining the beam can be sent to the user terminal by the network node in a variety of ways. For example, it can be included in the conditional reconfiguration configuration information and sent to the user terminal, or it can be sent to the user terminal through a broadcast message or dedicated signaling (that is, sent before the conditional reconfiguration is configured or sent along with the conditional reconfiguration). When the auxiliary information for determining the beam is included in the conditional reconfiguration configuration information and sent to the user terminal, the auxiliary information for determining the beam can be included in the execution conditions related to the beam information in the conditional reconfiguration configuration information, or can be included outside the execution conditions related to the beam information in the conditional reconfiguration configuration information.

[0122] The conditional reconfiguration method provided in an embodiment of the present application enables a network node to send a reconfiguration message containing execution conditions related to beam information and auxiliary information for determining the beam to a user terminal, thereby assisting the user terminal in determining appropriate access measurement target cells and associated target cells, thereby improving the success rate and reliability of switching.

[0123] Optionally, the configuration information of the measurement target cell, the configuration information of the associated target cell, the cell-level execution conditions of the measurement target cell, and the execution conditions related to the beam information included in the conditional reconfiguration configuration information satisfy at least one or more of the following:

[0124] Contains configuration information of the measurement target cell and configuration information of an associated target cell, cell-level execution conditions for measuring the target cell, and execution conditions related to beam information corresponding to the associated target cell;

[0125] Specifically, the conditional reconfiguration configuration information may include configuration information of a measurement target cell and configuration information of an associated target cell, cell-level execution conditions of the measurement target cell, and execution conditions related to the beam information corresponding to the associated target cell. Taking the measurement target cell as PCell as an example, for example, for candidate target PCell 1, it corresponds to multiple candidate target PSCells (such as PSCell 1, PSCell 2 and PSCell 3), then one conditional reconfiguration configuration information may include configuration information of PCell 1 and configuration information of PSCell 1, cell-level execution conditions of PCell 1, and execution conditions related to the beam information corresponding to PSCell 1. Another conditional reconfiguration configuration information may include configuration information of PCell 1 and configuration information of PSCell 2, cell-level execution conditions of PCell 1, and execution conditions related to the beam information corresponding to PSCell 2. Another conditional reconfiguration configuration information may include configuration information of PCell1 and configuration information of PSCell 3, cell-level execution conditions of PCell 1, and execution conditions related to the beam information corresponding to PSCell 2. 3 corresponds to the execution conditions related to the beam information.

[0126] Contains configuration information of a measurement target cell and configuration information of at least one associated target cell, cell-level execution conditions for the measurement target cell, and execution conditions related to beam information corresponding to each associated target cell;

[0127] Specifically, the conditional reconfiguration configuration information may include configuration information of a measurement target cell and configuration information of at least one associated target cell, cell-level execution conditions of the measurement target cell, and execution conditions related to the beam information corresponding to each associated target cell. Taking the measurement target cell as PCell as an example, for example, for candidate target PCell 1, it corresponds to multiple candidate target PSCells (such as PSCell 1, PSCell 2 and PSCell 3), then a conditional reconfiguration configuration information may include configuration information of PCell 1 and configuration information of PSCell1, PSCell 2 and PSCell 3, cell-level execution conditions of PCell 1, and execution conditions related to the beam information corresponding to PSCell 1, PSCell 2 and PSCell 3.

[0128] The configuration information of the measurement target cell includes synchronization reconfiguration configuration information or mobility control information;

[0129] The configuration information of the associated target cell includes synchronization reconfiguration configuration information or mobility control information.

[0130] The following takes the measurement target cell as PCell as an example to illustrate the generation process of the configuration information of the measurement target cell and the configuration information of the associated target cell.

[0131] Example 1: Process of generating configuration information including PCell and corresponding PSCell on the target MN side

[0132] Step 1: The target MN side obtains the candidate target PSCell cell determined by the target SN side, and the PSCell addition or change configuration information generated by it for the candidate target PSCell cell.

[0133] Step 2: The target MN side selects a candidate target PCell cell from the PCell cells recommended by the source MN side.

[0134] Step 2-1: For the case where the PCell switching configuration information includes configuration information of a PSCell addition or change: for each candidate target PCell cell, the target MN side generates PCell switching configuration information including configuration information of only one candidate target PSCell cell.

[0135] Step 2-2: For the case where the PCell handover configuration information includes configuration information for multiple PSCell additions or changes: For each candidate target PCell cell, the target MN generates PCell handover configuration information that includes the configuration information of all candidate target PSCell cells received from the target SN. The PSCells can be in the same CellGroup or different CellGroups.

[0136] Step 3: The target MN side transmits the generated PCell handover configuration information containing the configuration information of one or more PSCell additions or changes to the source MN side.

[0137] Optionally, the execution condition related to the beam information includes at least one of the following:

[0138] beam identification information;

[0139] Cell group ID;

[0140] Associated target cell ID.

[0141] Specifically, the execution conditions related to the above-mentioned beam information may include at least one of the beam identification information, the cell group identification Cell group ID (i.e., the cell group identification of the associated target cell) and the associated target cell identification. For example, the execution conditions related to the beam information may include the beam identification information, or may include the beam identification information and the cell group identification Cell group ID, or may include the beam identification information and the associated target cell identification, or may include the beam identification information, the cell group identification Cell group ID and the associated target cell identification.

[0142] The beam identification information may include at least one of a beam index index, a synchronization signal block index SSB index, and a channel state information reference signal index CSI RS index.

[0143] Optionally, the execution condition related to the beam information includes at least one of the following:

[0151] The cell group ID is determined by the source master node MN.

[0152] Specifically, the execution conditions related to the above beam information can be determined by the target measurement node or the source master node, and can be generated by the target measurement node or the source master node.

[0153] In the scenario where the target cell to be measured is a PCell, the target measurement node is the target master node MN; in the scenario where the target cell to be measured is a PSCell, the target measurement node is the target secondary node SN.

[0161] The correspondence may also be identified in an implicit manner, that is, the execution conditions related to the beam information correspond one-to-one with the associated PSCell configuration. For example, for the conditional reconfiguration configuration information whose signaling structure is "including configuration information for PCell switching and configuration information for adding or changing a PSCell, cell-level execution conditions, and execution conditions related to the corresponding beam information", the conditional reconfiguration configuration information only contains one corresponding execution condition related to the beam information.

[0180] The beam identifier may be at least one of a beam index, an SSB index, and a CSI-RS index.

[0181] Step 3: The target MN sends a conditional feedback message to the source MN, which includes at least one of the following:

[0182] Execution conditions related to the beam information generated by encoding on the target MN side;

[0183] The correspondence between the execution conditions related to the beam information encoded and generated on the target MN side and the candidate PSCell cells.

[0184] Optionally, the auxiliary information used to determine the beam includes at least one of the following:

[0185] Beam signal strength threshold;

[0186] Instructions for selecting the best beam.

[0187] Specifically, the above-mentioned auxiliary information for determining the beam may include at least one of a beam signal strength threshold and indication information for selecting the best beam. For example, the auxiliary information for determining the beam may be a beam signal strength threshold, or it may be indication information for selecting the best beam, or it may be both a beam signal strength threshold and indication information for selecting the best beam.

[0188] Optionally, the auxiliary information used to determine the beam includes at least one of the following:

[0189] Auxiliary information used to determine the beam determined by the target measurement node;

[0190] Auxiliary information generated by the target measurement node for beam determination;

[0192] Auxiliary information generated by the source master node MN for determining the beam.

[0193] Specifically, the auxiliary information for determining the beam may be determined by the target measurement node or the source master node, and may be generated by the target measurement node or the source master node.

[0194] In the scenario where the target cell to be measured is a PCell, the target measurement node is the target master node MN; in the scenario where the target cell to be measured is a PSCell, the target measurement node is the target secondary node SN.

[0211] Specifically, in the embodiment of the present application, the network node may be a source master node MN. The measurement target cell may be a PCell or a PSCell. For scenarios where the measurement target cell is a PCell, the associated target cell is a PSCell. For scenarios where the measurement target cell is a PSCell, the associated target cell is a PCell.

[0212] To enable the user terminal to select a suitable candidate target PCell and its associated candidate target PSCell, or to enable the user terminal to select a suitable candidate target PSCell and its associated candidate target PCell, the network node may send a reconfiguration message containing one or more conditional reconfiguration configuration information and auxiliary information for beam determination to the user terminal. The conditional reconfiguration configuration information includes at least configuration information of the measurement target cell, configuration information of the associated target cell, cell-level execution conditions of the measurement target cell, and execution conditions related to beam information.

[0213] After receiving the above-mentioned reconfiguration message and the auxiliary information used to determine the beam, the user terminal can perform measurement evaluation on the candidate measurement target cell based on the cell-level execution condition of the measurement target cell. When the measurement evaluation finds that the cell-level execution condition of a candidate measurement target cell is met, the user terminal can determine that the candidate measurement target cell is the access measurement target cell.

[0214] After determining the access measurement target cell, the user terminal can determine the associated target cell corresponding to the access measurement target cell based on the execution conditions related to the beam information and the auxiliary information used to determine the beam, and access the determined access measurement target cell and the determined associated target cell.

[0219] Specifically, the conditional reconfiguration configuration information may include configuration information of a measurement target cell and configuration information of an associated target cell, cell-level execution conditions of the measurement target cell, and execution conditions related to the beam information corresponding to the associated target cell. Taking the measurement target cell as PCell as an example, for example, for candidate target PCell 1, it corresponds to multiple candidate target PSCells (such as PSCell 1, PSCell 2 and PSCell 3), then one conditional reconfiguration configuration information may include configuration information of PCell 1 and configuration information of PSCell 1, cell-level execution conditions of PCell 1, and execution conditions related to the beam information corresponding to PSCell 1.

For example, the execution conditions related to the beam information may include the beam identification information, or may include the beam identification information and the cell group identification Cell group ID, or may include the beam identification information and the associated target cell identification, or may include the beam identification information, the cell group identification Cell group ID and the associated target cell identification.

For example, the auxiliary information for determining the beam may be a beam signal strength threshold, or it may be indication information for selecting the best beam, or it may be both a beam signal strength threshold and indication information for selecting the best beam.

[0234] Optionally, performing measurement evaluation on a measurement target cell and determining access to the measurement target cell includes:

[0235] The measurement evaluation selects a measurement target cell that meets the cell-level execution conditions and determines access to the measurement target cell.

[0236] Specifically, after the user terminal receives the above-mentioned reconfiguration message and the auxiliary information used to determine the beam, it can perform measurement evaluation on the candidate measurement target cell based on the cell-level execution condition of the measurement target cell. When the measurement evaluation finds that the cell-level execution condition of a candidate measurement target cell is met, the user terminal can determine that the candidate measurement target cell is the access measurement target cell.

[0237] Optionally, the determining the associated target cell based on the execution condition related to the beam information and the auxiliary information for determining the beam, and accessing to determine the access measurement target cell and determining the associated target cell includes:

[0238] Determining, based on the auxiliary information used to determine the beam, a target beam for accessing the determined measurement target cell;

[0239] Based on the target beam and execution conditions related to the beam information, the associated target cell is determined.

[0240] Specifically, after determining the access measurement target cell, the user terminal can determine the target beam of the determined access measurement target cell based on the auxiliary information used to determine the beam, and determine the associated target cell corresponding to the access measurement target cell based on the target beam and the execution conditions related to the beam information, and access the determined access measurement target cell and the determined associated target cell.

[0241] Optionally, determining a target beam of the target cell to be measured based on the auxiliary information used to determine the beam includes at least one of the following:

[0242] Selecting a beam with the best signal quality from the beam measurement results of the target cell and determining the beam as the target beam;

[0243] Selecting a beam with a signal quality higher than a threshold from the beam measurement results of the target cell, and selecting the beam with the best signal quality as the target beam;

[0244] A beam with a signal quality higher than a threshold is selected from the beam measurement results of the target cell, and a beam is selected from the beam to be determined as the target beam.

[0245] Specifically, after determining the access measurement target cell, the user terminal can determine the target beam of the determined access measurement target cell in a variety of ways based on the instruction information or protocol provisions on the network side and the auxiliary information used to determine the beam.

[0246] For example, the user terminal can select the beam with the best signal quality from the beam measurement results of the target cell and determine the beam as the target beam; the user terminal can also select the beam with signal quality higher than the threshold from the beam measurement results of the target cell, and select the beam with the best signal quality as the target beam; the user terminal can also select the beam with signal quality higher than the threshold from the beam measurement results of the target cell, and select any one beam as the target beam.

[0247] The beam measurement result may be at least one of an SSB signal measurement result and a CSI-RS signal measurement result.

[0248] Optionally, determining the associated target cell based on the target beam and execution conditions related to the beam information includes:

[0249] Selecting, in the execution condition related to the beam information, a candidate associated target cell corresponding to a beam identifier that is identical to the indication information associated with the determined target beam as the associated target cell;

[0250] The determined indication information associated with the target beam is at least one of the following:

[0251] beam index index;

[0252] Synchronization signal block index SSB index;

[0253] Channel State Information Reference Signal Index CSI RS index.

[0254] Specifically, after determining the target beam, the user terminal may determine the associated target cell corresponding to the access measurement target cell based on the target beam and the execution conditions related to the beam information. Specifically, the candidate associated target cell corresponding to the beam identifier that is the same as the indication information associated with the determined target beam in the execution conditions related to the beam information may be selected as the associated target cell. The indication information associated with the determined target beam may be at least one of a beam index index, a synchronization signal block index SSB index, and a channel state information reference signal index CSI RS index.

[0255] For example, the user terminal can determine the beam index associated with the target beam based on the determined target beam, and select the candidate associated target cell corresponding to the beam index that is the same as the beam index associated with the determined target beam from the execution conditions related to the beam information as the associated target cell.

[0256] For another example, the user terminal can also determine the SSBindex associated with the target beam based on the determined target beam, and select the candidate associated target cell corresponding to the same SSB index as the SSB index associated with the determined target beam from the execution conditions related to the beam information as the associated target cell.

[0257] For another example, the user terminal can also determine the CSI RSindex associated with the target beam based on the determined target beam, and select the candidate associated target cell corresponding to the CSI RS index that is the same as the CSI RS index associated with the determined target beam as the associated target cell from the execution conditions related to the beam information.

[0258] The following takes a scenario where the measurement target cell is a PCell and the association target cell is a PSCell as an example to illustrate the above conditional reconfiguration method through a specific embodiment.

[0259] Example 6: The source MN sends an RRC reconfiguration message with one or more conditional reconfiguration configuration information (taking the measurement target cell as PCell as an example)

[0260] Step 1: The source MN generates conditional reconfiguration configuration information for each candidate PCell and its corresponding candidate PSCell. The conditional reconfiguration configuration information includes at least one of the following:

[0261] (1) Configuration information for PCell switching and configuration information for adding or changing a PSCell, cell-level execution conditions, and execution conditions related to the corresponding beam information.

[0262] The execution conditions related to the beam information include: a beam identifier associated with a candidate target PSCell cell, and / or a candidate target PSCell identifier, and / or a Cell groupID used to determine the candidate target PSCell.

[0263] (2) Configuration information for PCell switching and configuration information for adding or changing at least one PSCell, cell-level execution conditions, and execution conditions related to the beam information associated with each PSCell corresponding to the PCell.

[0264] The execution conditions related to the beam information include: the beam identifier associated with each candidate target PSCell cell, and / or each candidate target PSCell identifier, and / or the Cell groupID used to determine each candidate target PSCell.

[0265] (3) Auxiliary information used to determine the beam.

[0266] The configuration information of the PCell switching and the configuration information of adding or changing one or at least one PSCell are provided by the target MN side to the source MN side.

[0267] The execution conditions related to the beam information may be generated by the source MN side (refer to Example 2), or may be generated by the target MN side and transmitted to the source MN side (refer to Example 3).

[0268] The auxiliary information used to determine the beam can be generated by the source MN side (refer to Example 4) or generated by the target MN side (refer to Example 5).

[0269] Step 2: The source MN generates an RRC reconfiguration message containing one or more conditional reconfiguration configuration information and sends it to the UE.

[0270] Step 3. Optionally, the source MN side may also send down a dedicated signaling containing auxiliary information for determining the beam, or the source MN side may broadcast the auxiliary information for determining the beam (the order of steps 3 and 4 is not important).

[0271] Step 4: The UE receives an RRC reconfiguration message with one or more conditional reconfiguration configuration information, obtains the cell-level execution conditions contained in each conditional reconfiguration configuration information, and the execution conditions related to the beam information.

[0272] Step 5: The UE starts to measure and evaluate the candidate PCell cell and its associated candidate PSCell cell based on the cell-level execution conditions.

[0273] Step 6. Optionally, corresponding to step 4, the UE obtains the auxiliary information used to determine the beam through dedicated signaling; or the UE obtains the auxiliary information used to determine the beam from the system message (steps 6 and 7 do not distinguish between the order).

[0274] Step 7. When the measurement and evaluation finds that the cell-level execution conditions of a candidate PCell are met, the UE selects the corresponding target PSCell cell based on the execution conditions related to the beam information contained in the conditional reconfiguration-related configuration information, and / or the auxiliary information used to determine the beam. The specific process refers to Example 7.

[0275] Example 7: The UE selects the corresponding target PSCell cell based on the execution conditions related to the beam information and / or the auxiliary information for determining the beam (taking the measurement target cell as the PCell as an example)

[0276] Step 1: The UE determines the target beam based on the auxiliary information used to determine the beam. The auxiliary information for determining the beam can be in the conditional reconfiguration configuration information, or obtained by the UE from dedicated signaling or system messages, and / or specified by the UE based on the protocol.

[0277] Step 1a: If the auxiliary information used to determine the beam instructs the UE to select the beam with the strongest signal, then: the UE selects the beam with the best signal quality from the beam measurement results of the PCell and determines the beam as the target beam.

[0278] Step 1b: If the auxiliary information used to determine the beam indicates the UE beam signal strength threshold, then:

[0279] (1) The UE selects a beam with a signal quality higher than a threshold from the beam measurement results of the PCell, and selects the beam with the best signal quality from among them to determine the beam as the target beam; or

[0280] (2) The UE selects a beam with a signal quality higher than a threshold from the beam measurement results of the PCell, and selects any one beam from the beam to determine the beam as the target beam.

[0281] The above beam measurement result may be a measurement result of an SSB signal or a CSI-RS signal.

[0282] Step 2a: The UE determines the beam index associated with the target beam based on the selected target beam, and selects the candidate PSCell corresponding to the beam index identical to the indication information associated with the determined target beam as the target PSCell from the execution conditions related to the selected beam information.

[0283] Step 2b: The UE determines the SSB index associated with the target beam based on the selected target beam, and selects the candidate PSCell corresponding to the same SSB index as the indication information associated with the determined target beam as the target PSCell from the execution conditions related to the selected beam information.

[0284] Step 2c: The UE determines the CSI RS index associated with the target beam based on the selected target beam, and selects the candidate PSCell corresponding to the CSI RS index with the same indication information associated with the determined target beam as the target PSCell from the execution conditions related to the beam selection information.

[0285] Step 3: The UE accesses the PCell and the target PSCell.

[0286] Example 8: The above-mentioned conditional reconfiguration method can also be applied to the scenario where the measurement target cell is a PSCell. Cell-level execution conditions and additional beam information-related execution conditions are configured for the candidate target PSCell. The beam information-related execution conditions correspond one-to-one to the candidate target PCell. When determining to add or switch the PSCell, the appropriate PCell access is selected according to the beam information. That is, the UE evaluates the measurement results of the candidate PSCell, and when the configured cell-level execution conditions are met, it determines the target PSCell and determines the target beam. The target beam, as in the above-mentioned embodiment, can be the best beam of the target PSCell, or the best beam that meets the configuration threshold, or a beam that meets the configuration threshold. After determining the target beam, the UE determines the target PCell associated with the target beam, thereby completing access to the target PCell and the target PSCell.

[0287] The association relationship between the candidate PCell and the beam is determined and / or generated by the target SN side, or can also be determined and / or generated by the target MN side.

[0288] The execution conditions related to the beam information are generated by the target SN side or the target MN side, and sent by the target MN side to the source MN side.

[0289] It should be noted that, since the embodiment of the conditional reconfiguration method when the measurement target cell is a PSCell is similar to the embodiment of the conditional reconfiguration method when the measurement target cell is a PCell, the repeated parts are not repeated here.

[0290] The methods and devices provided in the various embodiments of the present application are based on the same application concept. Since the methods and devices solve problems based on similar principles, the implementation of the devices and methods can refer to each other, and the repeated parts will not be repeated.
