DETAILED DESCRIPTION OF THE INVENTION

[0042] In the present disclosure, the term "and / or" describing an association relationship between related objects means that three relationships can exist, for example, A and / or B can represent three cases: A exists alone, A and B exist together, and B exists alone. The character " / " generally indicates that the related objects before and after it are in an "or" relationship.

[0043] The term "plurality" in the embodiments of the present disclosure means two or more, and other counters are analogous thereto.

[0044] The R17 standard feMIMO (Further Enhanced MIMO) project considers the ICBM (Inter-cell beam management) mechanism. The basic process is that the network sends candidate TRPs (Transmission and Reception Points) and their beam measurement configuration information to the terminal (UE). After receiving the configuration information, the UE performs corresponding L1 (Layer 1) measurements based on the configuration information and reports the measurement results to the network device. If the network device finds that the quality of the current TRP signal is poor through the L1 measurement results reported by the UE, the network will Layer 2( L2 ) The command is sent to the UE to change to a TRP with better signal quality without changing the serving cell and continue data transmission. The R18 NR mobility project is expected to consider scenarios where the serving cell is changed based on the R17 ICBM.

[0045] R18 New radio ( NR )In the mobility project, we consider a scenario where the serving cell changes its L1 / L2 mobility. This requires the UE to be pre-configured with beam measurement configuration and candidate cell configuration information. However, after the UE receives the pre-configured candidate cell configuration information, the UE does not know how to process or apply this configuration information, which may result in the UE applying the configuration information incorrectly and failing to change the serving cell.

[0046] In order to solve the above technical problems, an embodiment of the present disclosure provides a method for processing L1 / L2 mobility configuration information, including configuration information of each candidate cell related to pre-configured L1 / L2 mobility transmitted from a network device.

[0053] 2 is a flowchart of a method for processing L1 / L2 mobility configuration information provided by this embodiment. As shown in FIG. 2, this embodiment provides a method for processing L1 / L2 mobility configuration information, the execution subject of which is a terminal. The specific steps of this method are as follows:

[0054] In step S201, a network device transmits a pre-configured L1 / L2 mobility configuration information for each candidate cell. R Receives an RC message.

[0055] In this embodiment, in a scenario where the L1 / L2 mobility of a serving cell is changed (L1 / L2 mobility with serving cell change), the network device can send configuration information of each candidate cell related to pre-configured L1 / L2 mobility to the terminal through an RRC message.

[0056] In one possible embodimentThe configuration information of each candidate cell in this embodiment is as follows: First configuration information corresponding to each candidate cell, including physical layer configuration information; physical layer, Media Access Control ( MAC ) Layer and Radio link control ( RLC ) second configuration information corresponding to each candidate cell, including layer configuration information; Physical layer, MAC layer, RLC layer and Packet Data Integration Protocol ( PDCP ) third configuration information corresponding to each candidate cell, including layer configuration information; Contains at least one of the following:

[0057] where: In one possible embodiment In a scenario where each candidate cell does not span a DU (Distributed Unit), corresponding first configuration information may be configured for each candidate cell, i.e., each candidate cell shares configuration information for the MAC layer, RLC layer, and PDCP layer, but has different configuration information for the physical layer; in a scenario where each candidate cell spans a DU, corresponding second configuration information may be configured for each candidate cell, i.e., each candidate cell shares configuration information for the PDCP layer, but has different configuration information for the physical layer, MAC layer, and RLC layer; and in a scenario where each candidate cell spans a CU (Centralized Unit), corresponding third configuration information may be configured for each candidate cell, i.e., each candidate cell has different configuration information for the physical layer, MAC layer, RLC layer, and PDCP layer.

[0058] In addition, the configuration information of each candidate cell can be any of the above configuration information for each candidate cell, and two or three sets of configuration information can be configured for each candidate cell. For example, first configuration information and second configuration information corresponding to each candidate cell can be configured, or first configuration information and third configuration information corresponding to each candidate cell can be configured, or second configuration information and third configuration information corresponding to each candidate cell can be configured, or first configuration information, second configuration information, and third configuration information corresponding to each candidate cell can be configured. The terminal can select one set of configuration information based on a network instruction and perform the following application and / or storage operations, or can independently select one set of configuration information and perform the application and / or storage operations.

[0059] In one possible embodiment ,The RRC message in this embodiment may include, but is not limited to, at least one of an RRC reconfiguration message, an RRC connection resumption message, an RRC connection establishment message, and an RRC connection re-establishment message.

[0060] In S202, apply and / or store operations are performed on the configuration information of each candidate cell.

[0061] In this embodiment, after obtaining the configuration information of each candidate cell regarding the pre-configured L1 / L2 mobility, the terminal can perform application operations and / or storage operations on the configuration information of each candidate cell. Specifically, the specific application operations and / or storage operations to be performed can be determined in advance, or appropriate application operations and / or storage operations can be selected according to the situation.

[0062] In one possible embodiment ,Performing application and / or storage operations on the configuration information of each candidate cell, unless inconsistent; -For any of the configuration information of each candidate cell received in the RRC message, if the configuration information of the candidate cell is included in the pre-stored configuration information, replace the pre-stored configuration information of the candidate cell with the newly received configuration information of the candidate cell, i.e., if the candidate cell included in the newly received configuration information of each candidate cell overlaps with the candidate cell included in the pre-stored configuration information of the candidate cell, replace the pre-stored old configuration information with the new configuration information for the overlapping candidate cell; and / or -For any of the configuration information of each candidate cell received in the RRC message, if the configuration information of the candidate cell is not included in the pre-stored configuration information, add the configuration information of the candidate cell to the pre-stored configuration information, i.e., if one or several candidate cells included in the newly received configuration information of each candidate cell are not included in the candidate cells included in the pre-stored configuration information of the candidate cells, add the newly received configuration information of the one or several candidate cells to the pre-stored configuration information of the candidate cells; and / or For any of the configuration information of each candidate cell received in the RRC message, if the network instruction is to delete the candidate cell, delete the configuration information of the candidate cell from the pre-stored configuration information, i.e., if the configuration information of each candidate cell includes a candidate cell deletion instruction or the terminal receives a candidate cell deletion instruction from a network device, delete the configuration information of the candidate cell corresponding to the candidate cell deletion instruction from the pre-stored candidate cell configuration information based on the candidate cell deletion instruction; and / or -Deleting pre-stored configuration information and storing newly received configuration information for each candidate cell in an RRC message, i.e., deleting all pre-stored configuration information for each candidate cell and storing complete configuration information for each candidate cell.

[0063] Here, the first three operations can be considered as operations of modifying, adding, and releasing based on pre-stored configuration information of candidate cells, and some of these operations can also be applied when the configuration information of each candidate cell is received for the first time, i.e., when the configuration information of the candidate cell is not pre-stored, and the last operation is an operation of deleting all the configuration information of the old candidate cell and storing the complete configuration information of the new candidate cell when the terminal receives the configuration information of a new candidate cell.

[0082] To further illustrate the above-mentioned method for processing L1 / L2 mobility configuration information, the embodiments of the present disclosure further provide the following examples for detailed illustration.

[0083] Regarding Example 1, The UE receives an RRC reconfiguration message indicating a change of serving cell. or When additional indication information and configuration information of each candidate cell regarding pre-configured L1 / L2 mobility are included, the method for processing L1 / L2 mobility configuration information may specifically include the following steps:

[0084] In step 1, the UE receives an RRC reconfiguration message sent from a network device, and the RRC reconfiguration message includes a change of serving cell. or Additional indication information and pre-configured configuration information for each candidate cell regarding L1 / L2 mobility are included, where the target serving cell is indicated in the serving cell change / addition indication information.

[0085] In one possible embodiment ,The configuration information of each candidate cell is First configuration information corresponding to each candidate cell, including physical layer configuration information; second configuration information corresponding to each candidate cell, including configuration information of a physical layer, a MAC layer, and an RLC layer; Third configuration information corresponding to each candidate cell, including configuration information of a physical layer, a MAC layer, an RLC layer, and a PDCP layer; Contains at least one of the following:

[0086] Furthermore, the following step 2-1, step 2-2, or step 2-3 can be performed for the configuration information of each different candidate cell, respectively.

[0087] In step 2-1, if the pre-configured configuration information of each candidate cell regarding L1 / L2 mobility includes physical layer configuration information configured for each candidate cell by the network device (for example, in the case of an intra-DU scenario), the UE may perform one or more of the application and / or storage operations of steps 2-1-1 to 2-1-7 on the configuration information of each candidate cell; In step 2-1-1, the UE applies common MAC layer, RLC layer, and PDCP layer configuration information (since the network device configures only physical layer configuration information for each candidate cell, other configuration information is not changed when changing the serving cell, i.e., common configuration information can be applied), and / or In step 2-1-2, the UE applies the pre-configured physical layer configuration information of the target serving cell in the configuration information of each candidate cell by default, and / or In step 2-1-3, the UE continues to apply the default physical layer configuration information used by the current serving cell, and / or In step 2-1-4, the network device introduces indication information into the configuration message to indicate whether the UE should apply the physical layer configuration information of the pre-configured target serving cell. When the UE receives this indication information, if the indication information indicates to apply the configuration information of the target serving cell, the UE applies the physical layer configuration information of the pre-configured target serving cell; if the indication information indicates not to apply the configuration information of the target serving cell, the UE does not apply the physical layer configuration information of the pre-configured target serving cell, and continues to apply the physical layer configuration information used by the current serving cell, or can apply the physical layer configuration information of the target serving cell from another source; and / or In step 2-1-5, the UE stores the physical layer configuration information of other candidate cells except the target serving cell in the configuration information of each candidate cell; and / or In step 2-1-6, the UE stores the physical layer configuration information of all pre-configured candidate cells in the configuration information of each candidate cell; In step 2-1-7, the UE performs the process of changing / adding a serving cell.

[0088] Here, there are no priority restrictions for the UE to change / add the serving cell and apply / store preconfigured information of the candidate cells.

[0089] In step 2-2, if the pre-configured configuration information of each candidate cell regarding L1 / L2 mobility includes configuration information of the physical layer, MAC layer, and RLC layer configured by the network device for each candidate cell (for example, in an inter-DU scenario), the UE may perform one or more of the application and / or storage operations of steps 2-2-1 to 2-2-7 on the configuration information of each candidate cell; In step 2-2-1, the UE applies common PDCP configuration information (since the network device has configured physical, MAC and RLC layer configuration information for each candidate cell, the PDCP configuration information is common configuration information), and / or In step 2-2-2, the UE applies the pre-configured physical layer, MAC layer, and RLC layer configuration information of the target serving cell in the configuration information of each candidate cell by default, and / or In step 2-2-3, the UE continues to apply the default physical layer, MAC layer, and RLC layer configuration information used by the current serving cell, and / or In step 2-2-4, the network device introduces indication information into the configuration message to indicate whether the UE should apply the physical layer, MAC layer, and RLC layer configuration information of the pre-configured target serving cell. When the UE receives this indication information, if the indication information indicates to apply the configuration information of the target serving cell, the UE applies the physical layer, MAC layer, and RLC layer configuration information of the pre-configured target serving cell; if the indication information indicates not to apply the configuration information of the target serving cell, the UE does not apply the physical layer, MAC layer, and RLC layer configuration information of the pre-configured target serving cell, and may continue to apply the physical layer, MAC layer, and RLC layer configuration information used by the current serving cell, or may apply the physical layer, MAC layer, and RLC layer configuration information of the target serving cell from another source; and / or In step 2-2-5, the UE stores the configuration information of the physical layer, MAC layer, and RLC layer of other candidate cells except the target serving cell in the configuration information of each candidate cell; and / or In step 2-2-6, the UE stores the configuration information of the physical layer, the MAC layer and the RLC layer of all pre-configured candidate cells in the configuration information of each candidate cell; In step 2-2-7, the UE performs the process of changing / adding a serving cell.

[0090] Here, there are no priority restrictions for the UE to change / add the serving cell and apply / store preconfigured information of the candidate cells.

[0091] In step 2-3, if the pre-configured configuration information of each candidate cell regarding L1 / L2 mobility includes configuration information of the physical layer, MAC layer, RLC layer, and PDCP layer configured by the network device for each candidate cell (for example, in an inter-CU scenario), the UE may perform one or more of the application and / or storage operations of steps 2-3-1 to 2-3-6 on the configuration information of each candidate cell; In step 2-3-1, the UE applies the pre-configured physical layer, MAC layer, RLC layer and PDCP layer configuration information of the target serving cell in the configuration information of each candidate cell by default; and / or In step 2-3-2, the UE continues to apply the default configuration information of the physical layer, MAC layer, RLC layer and PDCP layer used by the current serving cell, and / or In step 2-3-3, the network device introduces, into its configuration message, indication information indicating whether the UE should apply the physical layer, MAC layer, RLC layer, and PDCP layer configuration information of the pre-configured target serving cell. When the UE receives this indication information, if the indication information indicates to apply the target serving cell configuration information, the UE applies the physical layer, MAC layer, RLC layer, and PDCP layer configuration information of the pre-configured target serving cell; if the indication information indicates not to apply the target serving cell configuration information, the UE does not apply the physical layer, MAC layer, RLC layer, and PDCP layer configuration information of the pre-configured target serving cell, and may continue to apply the physical layer, MAC layer, RLC layer, and PDCP layer configuration information used by the current serving cell, or may apply the physical layer, MAC layer, RLC layer, and PDCP layer configuration information of the target serving cell from another source; and / or In step 2-3-4, the UE stores the configuration information of the physical layer, MAC layer, RLC layer, and PDCP layer of the other candidate cells except the target serving cell in the configuration information of each candidate cell; and / or In step 2-3-5, the UE stores the configuration information of the physical layer, MAC layer, RLC layer, and PDCP layer of all pre-configured candidate cells in the configuration information of each candidate cell; In step 2-3-6, the UE performs the process of changing / adding a serving cell.

[0092] Here, there are no priority restrictions for the UE to change / add the serving cell and apply / store preconfigured information of the candidate cells.

[0093] In the above example, when performing a storage operation on the configuration information of each candidate cell, specifically, For any of the configuration information of each candidate cell received in the RRC message, if the configuration information of the candidate cell is included in pre-stored configuration information, replacing the pre-stored configuration information of the candidate cell with the newly received configuration information of the candidate cell; and / or For each candidate cell configuration information received in the RRC message, if the pre-stored configuration information does not include the configuration information of the candidate cell, adding the configuration information of the candidate cell to the pre-stored configuration information; and / or For any of the configuration information of each candidate cell received in the RRC message, if the network instruction is to delete the candidate cell, deleting the configuration information of the candidate cell from the pre-stored configuration information; and / or This may include deleting pre-stored configuration information and storing newly received configuration information for each candidate cell in the RRC message.

[0094] In the above example, the specific storage method can include the following two methods:

[0095] In method 1, one UE variable is introduced to store the configuration information of each received pre-configured candidate cell, which can be stored in list form, i.e., one entry includes one candidate cell and its configuration information, specifically, the candidate cell's identification information, such as PCI (Physical Cell Identity), PCI+frequency point, CGI (Global Cell Identity), etc., and may also include one or more of the candidate cell's physical layer configuration information, MAC layer configuration information, RLC layer configuration information, PDCP layer configuration information, etc.

[0096] In method 2, multiple UE variables are introduced to store the configuration information of the received pre-configured candidate cells, i.e., one UE variable is introduced for each layer, and each UE variable may be in list form, with each entry corresponding to one candidate cell and its configuration information, specifically, it may include the candidate cell's identification information (PCI, PCI+frequency point, CGI, etc.), the physical layer configuration information corresponding to this candidate cell, or the MAC layer configuration information, or the RLC layer configuration information, or the PDCP layer configuration information.

[0097] The above-mentioned RRC reconfiguration message may be an RRC connection resumption message, an RRC connection establishment message, or an RRC connection re-establishment message.

[0098] Based on the above example, further, when the network device receives instruction information for changing or adding a serving cell transmitted via L1 and / or L2, it may identify configuration information of a target serving cell corresponding to the instruction information for changing or adding a serving cell from the stored configuration information of each candidate cell, and apply the configuration information of the target serving cell to realize the L1 / L2 mobility change of the serving cell.

[0099] Regarding Example 2, The RRC reconfiguration message contains the configuration information of each candidate cell for pre-configured L1 / L2 mobility, but the serving cell change or If no additional indication information is included, the method for processing L1 / L2 mobility configuration information may specifically include the following steps:

[0100] In step 1, the UE receives an RRC reconfiguration message sent from a network device, and the RRC reconfiguration message includes a change of serving cell. orNo additional indication information is included, but pre-configured configuration information of each candidate cell regarding L1 / L2 mobility is included, and this pre-configured configuration information of the candidate cell may be the configuration information of the pre-configured candidate cell that was originally transmitted, or may be updated configuration information of the pre-configured candidate cell.

[0101] Furthermore, the following step 2-1, step 2-2, or step 2-3 can be performed for the configuration information of each different candidate cell, respectively.

[0102] In step 2-1, if the pre-configured configuration information of each candidate cell regarding L1 / L2 mobility includes physical layer configuration information configured for each candidate cell by the network device (for example, in the case of an intra-DU scenario), the UE may perform one or more of the application and / or storage operations of steps 2-1-1 to 2-1-7 on the configuration information of each candidate cell; In step 2-1-1, if at least one candidate cell included in the configuration information of each candidate cell received by the UE is already present in the pre-stored candidate cell configuration information, the UE replaces the pre-stored old physical layer configuration information for the at least one candidate cell with the newly received pre-configured physical layer configuration information; and / or In step 2-1-2, if the configuration information of each candidate cell received by the UE includes a candidate cell different from a candidate cell in the configuration information of the pre-stored candidate cell, add the physical layer configuration information of the different candidate cell in the configuration information of each candidate cell to the configuration information of the pre-stored candidate cell; and / or In step 2-1-3, if the UE receives an instruction from the network device that the UE needs to delete the configuration information of a specific candidate cell and its physical layer, the UE deletes the configuration information of this candidate cell and its physical layer from the configuration information of the current UE's pre-stored candidate cell, and the above steps 2-1-1, 2-1-2, and 2-1-3 can be regarded as a delta configuration based on the configuration information of the current pre-stored candidate cell, i.e., incremental addition / modification / release of configuration information; and / or In step 2-1-4, the UE deletes all pre-stored configuration information for the candidate cells and stores all newly received configuration information for each candidate cell. This method can be considered a full config, i.e., complete reconfiguration, where when the UE receives new configuration information, it deletes all old configuration information and stores the complete new configuration information; and / or In step 2-1-5, the UE applies the physical layer configuration information of the current serving cell in the received configuration information of each candidate cell by default, i.e., updates the physical layer configuration information of the current serving cell; and / or In step 2-1-6, the UE continues to apply the default physical layer configuration information used by the current serving cell, or In step 2-1-7, the network introduces instruction information into the configuration message to indicate whether the UE should update the physical layer configuration information of the current serving cell. When the UE receives this instruction information, if the instruction information indicates that the configuration information of the current serving cell should be applied, the UE replaces the physical layer configuration information used by the current serving cell with the newly received physical layer configuration information corresponding to the current serving cell; if the instruction information indicates that the configuration information of the current serving cell should not be applied, the UE continues to apply the physical layer configuration information used by the current serving cell.

[0103] In step 2-2, if the pre-configured configuration information of each candidate cell regarding L1 / L2 mobility includes configuration information of the physical layer, MAC layer, and RLC layer configured by the network device for each candidate cell (for example, in an inter-DU scenario), the UE may perform one or more of the application and / or storage operations of steps 2-2-1 to 2-2-7 on the configuration information of each candidate cell; In step 2-2-1, if at least one candidate cell included in the configuration information of each candidate cell received by the UE is already present in the pre-stored candidate cell configuration information, the UE replaces the pre-stored old physical layer, MAC layer, and RLC layer configuration information for the at least one candidate cell with the newly received pre-configured physical layer, MAC layer, and RLC layer configuration information; and / or In step 2-2-2, if the configuration information of each candidate cell received by the UE includes a candidate cell different from a candidate cell in the pre-stored configuration information of the candidate cell, add the configuration information of the physical layer, MAC layer, and RLC layer of the different candidate cell in the configuration information of each candidate cell to the pre-stored configuration information of the candidate cell; and / or In step 2-2-3, if the UE receives an instruction from the network device that the configuration information of a specific candidate cell and its physical layer, MAC layer and RLC layer needs to be deleted, the UE deletes the configuration information of this candidate cell and its physical layer, MAC layer and RLC layer from the configuration information of the current UE's pre-stored candidate cell, and the above steps 2-1-1, 2-1-2, 2-1-3 can be regarded as delta configuration based on the configuration information of the current pre-stored candidate cell, i.e., incremental addition / modification / release of configuration information; and / or In step 2-2-4, the UE deletes all pre-stored configuration information for the candidate cells and stores all newly received configuration information for each candidate cell. This method can be considered as a full config, i.e., complete reconfiguration, where when the UE receives new configuration information, it deletes all old configuration information and stores the complete new configuration information; and / or In step 2-2-5, the UE applies the configuration information of the physical layer, MAC layer, and RLC layer of the current serving cell in the received configuration information of each candidate cell by default, i.e., updates the configuration information of the physical layer, MAC layer, and RLC layer of the current serving cell; and / or In step 2-2-6, the UE continues to apply the default configuration information of the physical layer, MAC layer, and RLC layer used by the current serving cell; and / Or, In step 2-2-7, the network introduces indication information into the configuration message indicating whether the UE should update the physical layer, MAC layer, and RLC layer configuration information of the current serving cell. When the UE receives this indication information, if the indication information indicates that the configuration information of the current serving cell should be applied, the UE replaces the physical layer, MAC layer, and RLC layer configuration information used by the current serving cell with the newly received physical layer, MAC layer, and RLC layer configuration information corresponding to the current serving cell; if the indication information indicates that the configuration information of the current serving cell should not be applied, the UE continues to apply the physical layer, MAC layer, and RLC layer configuration information used by the current serving cell.

[0104] In step 2-3, if the pre-configured configuration information of each candidate cell regarding L1 / L2 mobility includes configuration information of the physical layer, MAC layer, RLC layer, and PDCP layer configured by the network device for each candidate cell (for example, in an inter-CU scenario), the UE may perform one or more of the application and / or storage operations of steps 2-3-1 to 2-3-7 on the configuration information of each candidate cell; In step 2-3--1, if at least one candidate cell included in the configuration information of each candidate cell received by the UE is already present in the pre-stored configuration information of the candidate cell, the UE replaces the pre-stored old configuration information of the physical layer, MAC layer, RLC layer, and PDCP layer for the at least one candidate cell with the newly received pre-configured configuration information of the physical layer, MAC layer, RLC layer, RLC layer, and PDCP layer; and / or In step 2-3--2, if the configuration information of each candidate cell received by the UE includes a candidate cell different from the candidate cell in the pre-stored configuration information of the candidate cell, add the configuration information of the physical layer, MAC layer, RLC layer and PDCP layer of the different candidate cell in the configuration information of each candidate cell to the pre-stored configuration information of the candidate cell; and / or In step 2-3-3, if the UE receives an instruction from the network device that the configuration information of a specific candidate cell and its physical layer, MAC layer, RLC layer and PDCP layer needs to be deleted, the UE deletes the configuration information of this candidate cell and its physical layer, MAC layer, RLC layer and PDCP layer from the configuration information of the candidate cell pre-stored in the current UE, and performs the above step 2- 3 -1, 2- 3 -2, 2- 3 -3 can be considered as a delta configuration, i.e., an incremental addition / modification / release of configuration information based on the current pre-stored configuration information of the candidate cell; and / or In step 2-3-4, the UE deletes all pre-stored configuration information of the candidate cells and stores all newly received configuration information of each candidate cell, this method can be considered as full config, i.e., full reconfiguration, when the UE receives new configuration information, it deletes all old configuration information and stores the complete new configuration information; and / or In step 2-3-5, the UE applies the configuration information of the physical layer, MAC layer, RLC layer and PDCP layer of the current serving cell in the received configuration information of each candidate cell by default, i.e., updates the configuration information of the physical layer, MAC layer, RLC layer and PDCP layer of the current serving cell; and / or In step 2-3-6, the UE continues to apply the default configuration information of the physical layer, MAC layer, RLC layer and PDCP layer used by the current serving cell; and / Or, In step 2-3-7, the network introduces indication information into the configuration message indicating whether the UE should update the configuration information of the physical layer, MAC layer, RLC layer, and PDCP layer of the current serving cell. When the UE receives this indication information, if the indication information indicates that the configuration information of the current serving cell should be applied, the UE replaces the configuration information of the physical layer, MAC layer, RLC layer, and PDCP layer used by the current serving cell with the configuration information of the physical layer, MAC layer, RLC layer, and PDCP layer corresponding to the newly received current serving cell; if the indication information indicates that the configuration information of the current serving cell should not be applied, the UE continues to apply the configuration information of the physical layer, MAC layer, RLC layer, and PDCP layer used by the current serving cell.

[0105] After step 2-1, the following steps 3-1, 3-2 or 3-3 can be performed for the configuration information of each different candidate cell, respectively.

[0106] In step 3-1, when the UE receives an L1 / L2 serving cell change / addition command or an L3 serving cell change / addition command sent from the network device, i.e., when moving from one cell to another cell or adding a serving cell, the UE executes the serving cell change / addition command and applies the stored preconfigured physical layer configuration information corresponding to the target serving cell. For example, when the UE receives an L1 / L2 mobility command sent from the network device to move from cell A to cell B, the UE executes the L1 / L2 mobility command, i.e., moves from cell A to cell B, and applies the stored preconfigured physical layer configuration information corresponding to cell B. There is no priority requirement between the UE's execution of the mobility command and its application of the preconfigured physical layer configuration information corresponding to the target serving cell.

[0107] In step 3-2, when the UE receives an L1 / L2 serving cell change / addition command or an L3 serving cell change / addition command sent from the network device, i.e., when moving from one cell to another cell or adding a serving cell, the UE executes the serving cell change / addition command and applies the stored preconfigured physical, MAC, and RLC layer configuration information corresponding to the target serving cell. For example, when the UE receives an L1 / L2 mobility command sent from the network device to move from cell A to cell B, the UE executes the L1 / L2 mobility command, i.e., moves from cell A to cell B, and applies the stored preconfigured physical, MAC, and RLC layer configuration information corresponding to cell B. There is no priority requirement between the UE's execution of the mobility command and the application of the preconfigured physical, MAC, and RLC layer configuration information corresponding to the target serving cell.

[0110] In the above example, the specific storage method can include the following two methods:

[0111] In method 1, one UE variable is introduced to store the configuration information of each received pre-configured candidate cell, which can be stored in list form, i.e., one entry includes one candidate cell and its configuration information, specifically, the candidate cell's identification information, such as PCI (Physical Cell Identity), PCI+frequency point, CGI (Global Cell Identity), etc., and may also include one or more of the candidate cell's physical layer configuration information, MAC layer configuration information, RLC layer configuration information, PDCP layer configuration information, etc.

[0112] In method 2, multiple UE variables are introduced to store the configuration information of the received pre-configured candidate cells, i.e., one UE variable is introduced for each layer, and each UE variable may be in list form, with each entry corresponding to one candidate cell and its configuration information, specifically, it may include the candidate cell's identification information (PCI, PCI+frequency point, CGI, etc.), the physical layer configuration information corresponding to this candidate cell, or the MAC layer configuration information, or the RLC layer configuration information, or the PDCP layer configuration information.

[0113] The above-mentioned RRC reconfiguration message may be an RRC connection resumption message, an RRC connection establishment message, or an RRC connection re-establishment message.
