Embodiments for Carrying Out the Invention

[0066] Exemplary embodiments will be described in detail in this specification, and the examples are shown in the accompanying drawings. When the following description relates to the accompanying drawings, the same numerals in different accompanying drawings indicate the same or similar elements unless otherwise specified. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure.

[0067] It should be noted that the method provided in any one of the embodiments of the present disclosure may be executed alone, any of the implementation forms in the embodiments may be executed alone, may be executed in combination with other embodiments, or possible implementation methods in other embodiments, and may also be executed in combination with any of the technical solutions in the related art.

[0068] The communication method provided by the embodiments of the present disclosure can be applied in a wireless communication system. In the wireless communication system, a mobile station accesses a wireless access network via a wireless access network network device such as a base station, and the wireless access network network device and the core network network device complete the reverse and forward transmission of data to execute various communication services.

[0069] A wireless communication system refers to a network that provides a wireless communication function. A wireless communication system can use various communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA (registered trademark)), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier FDMA (SC-FDMA), carrier sense multiple access with collision avoidance, etc. Different networks can be classified into future evolved networks such as 2G (generation) networks, 3G networks, 4G networks, or 5G networks based on factors such as capacity, rate, and latency. The 5G network may also be called a New Radio (NR) network. For ease of explanation, in this disclosure, the wireless communication network may simply be referred to as a network or a system. The network in this disclosure may include a Radio Access Network (RAN) and a Core Network (CN). The network includes network devices that may be wireless access network nodes, core network functions, etc. Here, the wireless access network node is also called a base station. The network can provide network services to terminals via network devices, and different operators can provide different network services to terminals, which can be understood as different operator networks if the operators are different.

[0070] Here, the current wireless communication system supports the selective activation of a cell group (CG) in multi-radio dual connectivity (MR-DC).

[0071] MR-DC is the intra-evolution universal terrestrial radio access (Intra-E-UTRA) dual connectivity of a generalized same-evolution universal mobile telecommunications system (UMTS). Here, the terminal can utilize radio resources provided from two different schedulings arranged in two different 5G radio access networks (NG-RAN) nodes connected by a non-ideal backhaul. One provides NR access, and the other provides E-UTRA or NR access. One functions as a master node (MN), and the other functions as a secondary node (SN). The MN and SN are connected via a network interface, and at least the MN is connected to the core network.

[0072] Here, MR-DC is supported by the evolved packet core (EPC) of 4G. Here, MR-DC is supported by E-UTRAN through (E-UTRAN-NR DC, EN-DC), and the architecture of EN-DC is shown in FIG. 1. Referring to FIG. 1, it is shown that the terminal is connected to an eNB operating as an MN and an en-gNB operating as an SN. The eNB is connected to the EPC via the S1 interface and to the en-gNB via the X2 interface. The en-gNB may be connected to the EPC via the S1-U interface or to another en-gNB via the X2-U interface.

[0073] Here, the 5G core network (5GC) supports MR-DC. As one method, the NG-RAN supports (NG-RAN E-UTRA-NR Dual Connectivity, NGEN-DC) dual connectivity, and the terminal is connected to the NG-eNB as the MN and to the gNB as the SN. The NG-eNB is connected to the 5GC, and the gNB is connected to the ng-eNB via the X2-U interface. As another method, the NG-RAN supports NR-E-UTRA DC (NR-E-UTRA Dual Connectivity, NE-DC). Here, the terminal is connected to the gNB as the MN and to the ng-eNB as the SN. The gNB is connected to the 5GC, and the ng-eNB is connected to the gNB via the Xn interface. As yet another method, the NG-RAN supports (NR-NR DC, NR-DC). Figure 2 illustrates the network architecture diagram of NR-DC. Here, the terminal is connected to the gNB operating as the MN and to another gNB operating as the SN. The primary gNB is connected to the 5GC via the NG interface, the two gNBs are connected via the Xn interface, and the secondary gNB can also be connected to the 5GC via the NG-U interface. Also, NR-DC can be used for the UE to access a single gNB, operates as both the MN and the SN, and constitutes both the MCG and the SCG.

[0074] Under dual connectivity, the terminal can access two cell groups: the Master Cell group (MCG) and the Secondary Cell group (SCG). Under the MCG, there may be multiple cells. One of the multiple cells is used to initiate the first access, and this cell is called the Primary Cell (PCell). The PCell is the most "primary" cell within the MCG. Figure 3 shows the structure of the MCG and SCG under dual connectivity. The PCell under the MCG and the Secondary Cell (SCell) under the MCG are combined by Carrier Aggregation (CA). The primary cell of the MCG is the PCell, and the secondary cell is the SCell. The primary and secondary cells of the SCG are the Primary Secondary Cell (PSCell) and the Secondary Cell (SCell), respectively. Since a lot of signaling is transmitted on the PCell and the PSCell, for the sake of convenience of explanation, the protocol collectively refers to the PCell and the PSCell as the special cell (sPCell). The sPCell is called the special cell in English.

[0075] As related technologies, Conditional Hopping (CHO), Conditional PSCell Change (CPC), and Conditional PSCell Addition (CPA) have been proposed. Among these, in CHO / CPC / CPA, after the terminal completes the random access to the target PCell / PSCell, it must cancel the CHO / CPC / CPA settings. Therefore, unless the network reconfigures and re-initializes CHO / CPC / CPA, the terminal will have no chance to continue CHO / CPC / CPA thereafter. Consequently, the waiting time for switching or SCG change increases, and the signaling overhead increases.

[0076] Therefore, selective activation of cell groups in MR-DC has been proposed, enabling subsequent settings to be executed without the need for network reconfiguration or re-initialization of selective activation setting information corresponding to the cell group even after the cell group (Cell group, CG) has been changed. As a result, signaling overhead and the interruption time of cell group changes can be reduced.

[0077] Here, the selective activation setting information of the cell group can include at least one of a setting ID, an activation condition (if possible), and a setting of the cell group / cell to be activated.

[0078] Here, the selective activation of the cell group can enable subsequent settings to be executed without the need for the network to reconfigure or re-initialize the selective activation setting of the corresponding cell group even after the cell group has been changed. Therefore, in the selective activation of the cell group, the network device can provide the terminal with the "cell group to be activated". The "cell group to be activated" can be activated or deactivated later without re-supplying the cell group settings.

[0079] In the selective activation of a cell group, the network device can provide the terminal device with a pre-set candidate target cell group or target cell. The terminal device can then activate or deactivate the pre-set candidate cell group or cell based on the settings (e.g., activation message) transmitted by the network device or the corresponding activation event without re-providing the settings of the cell group. Alternatively, in the selective activation of a cell group, it can be understood that the terminal device does not delete the selective activation setting information of the corresponding cell group after activating a new cell or cell group, or after applying a new cell setting or cell group setting, or after accessing a new cell or cell group.

[0080] The selective activation of cell groups is also called the activation of cell groups. By activating the cell group, even after the cell group or cell is changed, the corresponding activation setting information of the cell group can be executed without the need for network reconfiguration or re-initialization. Therefore, the activation of cell groups can reduce signaling overhead and the interruption time of cell group changes. The activation setting information of the cell group may include a setting ID and the setting of the target cell or the setting of the target cell group. Optionally, the activation setting information of the cell group can also include trigger conditions (also called execution conditions or activation conditions).

[0081] In an embodiment, the activation of a cell group is a mobility management process. By setting the activation setting of any cell group, the terminal device activates or deactivates the corresponding cell or cell group, or applies the corresponding cell setting or cell group setting, or accesses the cell or cell group according to the signaling transmitted by the network, the criteria specified by the protocol, or the autonomy of the terminal device, etc., including any mobility management process.

[0082] In one embodiment, the activation of a cell group is a mobility management process, including a mobility management process that does not delete or release some or all of the corresponding setting information after executing any mobility management process. Here, not deleting or releasing some or all of the corresponding setting information can also be called retaining some or all of the corresponding setting information.

[0083] In the present disclosure, the cell group is one or more of a primary cell group (MCG) and a secondary cell group (SCG). Here, the MCG includes one or more of a primary cell (PCell) and a secondary cell (SCell). Here, the SCG includes one or more of a primary secondary cell (PSCell) and a secondary cell (SCell).

[0084] In the present disclosure, the selective activation of a cell group may include cell selective activation or cell activation, for example, one or more of PCell activation, PSCell activation, and SCell activation.

[0085] In the related protocol, the activation and deactivation of the SCG are introduced, but such a form is applied to the state change of a single SCG and does not involve the state changes of multiple SCGs. However, currently, the introduction of multiple cell groups to be activated is supported, and it is possible to selectively activate cell groups from the multiple cell groups to be activated. However, since there is a possibility of being involved in the change of the cell group, in the current protocol, the specific operation of the terminal is not defined regarding how to selectively activate cell groups from the multiple cell groups to be activated. That is, the communication operation of the terminal for performing the selective activation of cells is not defined.

[0086] Therefore, the present disclosure provides a communication method for performing an activation process of a cell group based on setting information for selective activation of a cell group so as to clarify the communication operation of a terminal that performs selective activation of a cell group in order to assist the selective activation of the cell group.

[0087] Here, the cell group related to each of the following embodiments in the present disclosure may include one or more cells. The activation process of the cell group can be understood as the activation process of the cell group / cell. Therefore, the cell group related to the following embodiments in the present disclosure may be understood as a cell or a cell group.

[0088] It will be understood that the cell group related to the following embodiments of the present disclosure may be a primary cell group (MCG) or a secondary cell group (SCG), and the cell may be any one of a primary cell (PCell), a primary secondary cell (PSCell), and a secondary cell (SCell).

[0089] In the present disclosure, the cell group may refer to any one or more of a primary cell, a primary secondary cell, and a secondary cell.

[0090] Furthermore, it should be understood that the activation process of the cell group related to the present disclosure may include the activation process of the cell group, may also include the deactivation process of the cell group, or may include both the activation process and the deactivation process of the cell group.

[0091] Also, in the present disclosure, the activation process of the cell group may include the activation process of the cell.

[0092] The activation process of the cell related to the present disclosure may include the activation process of the cell, may also include the deactivation process of the cell, or may include both the activation process and the deactivation process of the cell.

[0104] In step S22, perform activation of the selected cell group and / or perform deactivation of the serving cell group.

[0105] It can be understood that the serving cell group involved in the embodiments of the present disclosure and the following embodiments is the currently activated cell group.

[0106] In an embodiment of the present disclosure, the configuration information for selective activation of a cell group includes, on the one hand, the cell group configuration information of the cell group to be activated. The configuration information for selective activation of the cell group may also include, on the other hand, the configuration information of the currently activated cell group.

Optionally, the configuration information for activation of a cell group may also include a trigger condition (which may also be referred to as an execution condition or an activation condition).

[0109] Here, the serving cell group in the embodiments of the present disclosure is the currently activated cell group. The selected cell group will become the serving cell group when it is successfully activated. The current serving cell group may be the "cell group to be activated" before activation.

[0211] In step S92, based on the indication information, determine the specific actions for performing the activation process of the cell group for the terminal.

[0212] Exemplarily, for a specific cell group / cell, by instructing a specific operation for performing the activation process of the cell group / cell using the instruction information transmitted from the network device, the terminal may determine a specific operation for the terminal to execute the activation process of the cell group / cell based on the instruction information transmitted from the network device.

[0219] FIG. 13 is a flowchart of a communication method shown according to an exemplary embodiment. As shown in FIG. 13, the communication method is used in a terminal and includes the following steps.

[0220] In step S101, indication information transmitted by a network device is received, and the indication information is used to indicate one or more activation operations to be performed on the selected cell group.

[0221] In step S102, based on the indication information, one or more activation operations to be performed on the selected cell group are determined.

[0222] Exemplarily, the activation operation includes one or more of the following, but is not limited thereto: a) Determine whether to perform RACH, such as starting RACH in a cell of the cell or cell group to be activated by the terminal based on the indication information. b) Perform BFD or stop performing BFD on the deactivated serving cell group.

For example, the terminal determines whether to perform downlink synchronization based on the indication information, and performs downlink synchronization in the cell of the cell or cell group to be activated.

[0223] The activation operation involved in the embodiments of the present disclosure may be an activation operation involved in the process that the terminal should execute to activate a cell group / cell, and / or the process that the terminal should execute to deactivate a cell group / cell, and / or the process that the terminal should execute to change a cell group / cell in the above-described embodiments, and it should be understood that the embodiments of the present disclosure are not limited thereto. For example, the embodiments of the present disclosure may determine whether to perform any one or more activation operations involved in the process that the terminal should execute to activate a cell group / cell, and / or the process that the terminal should execute to deactivate a cell group / cell, and / or the process that the terminal should execute to change a cell group / cell in the above-described embodiments based on the indication information.

[0224] It is further understood that the indication information transmitted by the network device in the embodiments of the present disclosure can be used to indicate at least one of the following: a) The activation form of the cell group for which the terminal performs selection. b) The specific operations when the terminal performs the activation process of the cell group. c) One or more activation operations performed on the selected cell group.

[0225] In the communication method provided by the embodiments of the present disclosure, the instruction information transmitted by the network device may be configured independently for each cell / cell group, or may be configured independently for selective activation settings for each cell / cell group. Here, the activation / deactivation of the cell group / cell determines whether to execute specific steps according to specific instruction information for this cell group / cell.

[0226] In the communication method provided by the embodiments of the present disclosure, the instruction information transmitted by the network device may be general instruction information, and the determination of whether to execute specific steps is made according to this instruction information regardless of which cell group / cell is activated / deactivated.

[0227] In the communication method provided by the embodiments of the present disclosure, the instruction information transmitted by the network device may be independent single instruction information transmitted independently, or may be carried in existing signaling. For example, in the embodiments of the present disclosure, the instruction information transmitted by the network device may be included in the selective activation setting of the cell group, and when this cell group is activated, the terminal determines whether to execute a process related to the activation process to be executed for this cell group according to the corresponding setting information. For example, in the present embodiments of the present disclosure, the instruction information may be included in the activation command, and when the terminal receives the activation command, it determines whether to execute a related process of the activation process to be executed for the above cell group according to the instruction information included in the activation command.

[0228] In one embodiment of the communication method provided by the embodiments of the present disclosure, the activation process to be executed for the cell group may be determined based on protocol rules or terminal implementation.

[0229] In one embodiment, as an example of the activation process for a cell group / cell, the activation process executed for a cell group determined based on protocol rules or terminal implementation includes one or more of the following: a) Execute PDCP reconfiguration in response to the update of the private key; b) Change the cell group / cell in response to the update of the private key to change the currently activated cell group / cell; c) When the trigger terminal activates the specified cell group / cell and the synchronization setting includes the setting information of the specified cell group / cell, start RACH in the specified cell group, or cell, or cell of the cell group; d) When the trigger terminal activates the specified cell group / cell and the BFD or RLM of the specified cell group / cell is stopped, start RACH for the specified cell group, or cell, or cell of the cell group.

[0230] The communication method provided in the embodiments of the present disclosure provides the operation of the terminal applicable to the selective activation of the cell group to support the selective activation of the cell group.

[0231] Here, the terminal activates one cell group (which may be referred to as the selected cell group or the selected cell group) among the "cell groups to be activated" including one or more of the following cases: a) If there is a serving cell group in the terminal currently, the serving cell group is deactivated and the selected cell group is activated. b) If there is no serving cell group in the terminal currently, the selected cell group is activated. c) If there is a serving cell group in the terminal currently, execute cell group change and start the switching process.

[0232] In the embodiments of the present disclosure, a serving cell group is a currently activated cell group. When the selected cell group is successfully activated, it becomes the serving cell group. The current serving cell group may be the "cell group to be activated" before activation. After being deactivated, the serving cell group becomes the cell group to be activated.

[0233] In particular, the communication method provided by the embodiments of the present disclosure also defines specific terminal operations for the terminal to activate / deactivate a cell group / cell. For example, during initial setup, the terminal reads the configuration information of the cell group / cell and applies the configuration of the corresponding cell group / cell to the configuration of the cell group that is activated in the initial state. For a deactivated cell group / cell, the terminal suspends the configuration corresponding to this cell group / cell. When an existing cell group / cell with a configuration is activated, the terminal applies or restores the configuration of the corresponding cell group / cell.

[0234] Here, in the embodiments of the present disclosure, the terminal may determine whether the activation of a deactivated cell group / cell requires the execution of a corresponding process based on the instruction information of the network device. For example, based on the instruction information of the network device, it is determined whether to activate the corresponding cell or cell group using an activation / deactivation decision or a switching decision. Further, for example, when deactivating the corresponding cell group / cell, the terminal determines whether to continue RLM / BFD based on the instruction information from the network device, and determines the specific operations of the terminal to execute the activation process of the cell group / cell based on the instruction information transmitted from the network device.

[0235] Based on the same concept, the embodiments of the present disclosure also provide a communication method applicable to network devices.

Case 2: In response to the presence of the serving cell group, change the current serving cell group to the selected cell group. In Case 3, in response to the absence of a serving cell group, activate the selected cell group.

[0245] In one embodiment, performing the activation of the selected cell group and / or performing the deactivation of the serving cell group includes, in response to the presence of the serving cell group, deactivating the serving cell group and activating the selected cell group.

[0246] In one embodiment, performing the activation of the selected cell group and / or performing the deactivation of the serving cell group includes, in response to the presence of the serving cell group, changing the current serving cell group to the selected cell group.

Here, in this mode, it can be understood that the current serving cell group / cell is the cell group / cell currently activated by the terminal. b) Execute a cell group / cell change and change the cell group / cell to which the current terminal is connected. Here, such a mode can be understood as changing from the connection to the current serving cell group / cell to the connection to the selected cell group / cell.
