Detailed ways

Embodiments of the present disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present disclosure and are not to be construed as limitations of the present disclosure. Among them, in the description of the present disclosure, unless otherwise stated, "/" means or, for example, A/B can mean A or B; "and/or" in this article is just an association describing the associated objects. Relationship means that three relationships can exist. For example, A and/or B can mean: A exists alone, A and B exist simultaneously, and B exists alone.

For ease of understanding, terminology involved in this disclosure is first introduced.

1.MR-DC

MR-DC (Multi-Radio Dual Connectivity, Multi-Radio Dual Connectivity) is a generalized Intra-E-UTRA (Evolved Universal Terrestrial Radio Access, Evolved Universal Terrestrial Radio Access) dual connectivity. Terminal equipment can utilize two different Radio resources provided by scheduling, which are located on two different NG (new radio, 5G new air interface)-RAN (radio access network) nodes, through non-ideal backhaul connections, one provides NR access, and the other provides E- UTRA or NR access. One serves as MN (Master Node, primary node) and the other serves as SN (Secondary Node, secondary node). MNs and SNs are connected through network interfaces, with at least one MN connected to the core network.

2. MR-DC with EPC

E-UTRAN supports MR-DC through E-UTRA-NR DC (EN-DC), in which the terminal device is connected to an eNB (evolved NodeB, evolved base station) acting as MN and an en-gNB (next generation NodeB) acting as SN , next generation base station). eNB is connected to EPC (Evolved Packet Core, evolved packet core) through the S1 interface and connected to en-gNB through the X2 interface. en-gNB can also be connected to the EPC through the S1-U interface and to other en-gNBs through the X2-U interface.

3. MR-DC with 5GC

A)E-UTRA-NR Dual Connectivity NGEN-DC

NG-RAN supports NG-RAN E-UTRA-NR dual connectivity (NGEN-DC), in which the terminal device is connected to one ng-eNB as the MN and one gNB as the SN. ng-eNB is connected to 5GC (5G Core, 5G core network), and gNB is connected to ng-eNB through the Xn interface.

B)NR-E-UTRA Dual Connectivity NE-DC

NG-RAN supports NR-E-UTRA DC (NE-DC), where the terminal device is connected to a gNB acting as MN and an ng-eNB acting as SN. gNB is connected to 5GC, and ng-eNB is connected to gNB through Xn interface.

4. NR-NR Dual Connectivity

NG-RAN supports NR-NR DC (NR-DC), where the terminal device is connected to one gNB acting as MN and another gNB acting as SN. The primary gNB is connected to the 5GC through the NG interface, the two gNBs are connected through the Xn interface, and the secondary gNB can also be connected to the 5GC through the NG-U interface. In addition, NR-DC can also be used for terminal equipment to access a single gNB, serving as MN and SN at the same time, and configuring MCG (Master Cell group, primary cell group) and SCG (Secondary Cell group, secondary cell group) at the same time. Under dual connectivity, terminal equipment can access two cell groups, namely MCG and SCG. Under MCG, there may be many Cells, one of which is used to initiate initial access. This cell is called PCell. As the name suggests, PCell is the most "main" cell in MCG. PCell under MCG and SCell under MCG are united through CA (Carrier Aggregation). The primary cell in MCG is PCell and the secondary cell is SCell; the primary and secondary cells in SCG are PSCell and the secondary cell is SCell. Because a lot of signaling is only sent on PCell and PSCell, for the convenience of description, a concept sPCell (special Cell, special cell) is also defined in the protocol. PCell and PSCell are collectively called sPCell.

5. Selective activation of cell groups:

In Rel-16 conditional handover (CHO) and in Rel-17 conditional PSCell change (CPC)/conditional PSCell addition (CPA), the terminal device configured with CHO/CPC/CPA must complete random access to the target PCell/PSCell. Release the CHO/CPC/CPA configuration. Therefore, if the network does not reconfigure and reinitialize CHO/CPC/CPA, the terminal will not have the opportunity to continue to perform CHO/CPC/CPA subsequently. This will increase the delay of handover or SCG change and increase the signal overhead, especially in the FR (Frequency Range, frequency range) 2 scenario, when the CG (Cell group, cell group) is frequently changed. Therefore, the selective activation of cell groups in MR-DC was proposed in the R18 mobility enhancement project, which can enable subsequent CHO/CPC/CPA to still be executed after the CG is changed, without the need for network re-establishment. Configure or reinitialize CHO/CPC/CPA. This can reduce signaling overhead and interruption duration of CG change.

In the selective activation of a cell group, the network device may provide a preconfigured candidate target cell group or target cell to the terminal device. The subsequent terminal device can activate or deactivate the preconfigured candidate cell group or cell according to the configuration (such as activation message) issued by the network device or the corresponding activation event, without re-providing the configuration of the cell group. In other words, in cell group selective activation, after activating a new cell or cell group, or applying a new cell configuration or cell group configuration, or after accessing a new cell or cell group, the terminal device will not delete the corresponding cell. Configuration information for group selective activation.

Selective activation of cell groups can also be called cell group activation. It can enable the corresponding configuration information to still be executed after the cell group or cell is changed, without the need for network reconfiguration or re-initialization of the corresponding cell group activation configuration information. This can reduce signaling overhead and downtime for cell group changes. The configuration information for cell group activation may include: configuration ID (identity, identification code) and the configuration of the target cell or the configuration of the target cell group. Optionally, the configuration information for cell group activation may also include trigger conditions (which may also be called execution conditions and activation conditions).

In the embodiment of the present disclosure, cell group activation is a mobility management process, including any configuration of cell group activation by configuring the terminal device according to the signaling sent by the network, or the criteria specified by the protocol, or the terminal device autonomously, etc. The method activates or deactivates the corresponding cell or cell group, or applies the corresponding cell configuration or cell group configuration or accesses the mobility management process of the cell or cell group.

In embodiments of the present disclosure, cell group activation is a mobility management process, including any mobility management process that does not delete or release corresponding part or all of the configuration information after executing the mobility process. Not deleting or releasing the corresponding part or all of the configuration information can also be called retaining the corresponding part or all of the configuration information.

In the present disclosure, the cell group is one or more of a main cell group (MCG) and a secondary cell group (SCG). The MCG includes one or more of the primary cell (Primary Cell, PCell) and the secondary cell (Secondary Cell, SCell). Among them, the SCG includes one or more of the Primary Secondary Cell (PSCell) and the Secondary Cell (SCell).

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