For the serving cell of the secondary node in the DC scenario, the current technology only involves the addition and change of the primary and secondary cells. How to configure the secondary cell corresponding to the secondary node for the terminal device is a problem that needs to be solved.

双连接：是指终端设备采用同一种无线接入技术接入到两个不同的网络设备；或者，终端设备采用两种不同的无线接入技术同时接入一个网络设备或者两个网络设备。可选地，终端设备与MN(Master Node，主节点)建立的连接称为MCG(Master Cell Group，主小区群)，主小区群里的主小区称为PCell；终端设备与SN(Secondary Node，辅节点)建立的连接称为SCG(Secondary Cell Group，辅小区群)，辅小区群里的主小区称为PScell。主节点和辅节点之间有一条叫做Xn-C的控制面链路，并且至少主节点通过接口NG-C连接到核心网络。Dual connection: means that the terminal device uses the same wireless access technology to access two different network devices; or, the terminal device uses two different wireless access technologies to simultaneously access one network device or two network devices. Optionally, the connection established between the terminal equipment and the MN (Master Node, master node) is called an MCG (Master Cell Group, the master cell group), and the master cell in the master cell group is called the PCell; the terminal equipment and the SN (Secondary Node, The connection established by the secondary node) is called an SCG (Secondary Cell Group, secondary cell group), and the primary cell in the secondary cell group is called a PScell.

As shown in Fig. 1a, the terminal device simultaneously accesses two base stations through the interface Uu: MeNB and SgNB. Optionally, MeNB is a 4G base station that provides S1-MME connection for terminal equipment, and is connected to the 4G core network as a control plane anchor point, and undertakes all control plane functions, so it is also called a master node; SgNB is a 5G base station and has no direct connection. To the control plane link of the core network, there is a control plane link called X2-C between SgNB and MeNB. SgNB does not undertake the control plane function, and its interaction with the control plane of the core network is carried out by MeNB, so it is called as a secondary node.
图1b为多无线电双连接场景的一种示意图。如图1b所示，终端设备被配置为通过接口Uu分别接入两个不同的节点，并利用由两个不同的节点提供的资源，一个节点提供NR接入，另一个节点提供E-UTRA或NR接入。 可选地，一个节点充当主节点，另一个节点充当辅节点。主节点和辅节点通过网络接口连接，并且至少主节点连接到核心网络。在NGEN-DC(NG-RAN E-UTRA-NR Dual Connectivity)中，辅节点提供NR接入，主节点提供E-UTRA接入；在NE-DC(NR-E-UTRA Dual Connectivity)中，主节点提供NR接入，辅节点提供E-UTRA接入；在NR-DC(NR-NR Dual Connectivity)中，主节点和辅节点均提供NR接入。FIG. 1b is a schematic diagram of a multi-radio dual connection scenario. As shown in Figure 1b, the terminal equipment is configured to access two different nodes respectively through the interface Uu, and utilize the resources provided by the two different nodes, one node provides NR access, the other node provides E-UTRA or NR access. Optionally, one node acts as the primary node and the other node acts as the secondary node. The primary node and the secondary node are connected by a network interface, and at least the primary node is connected to the core network. In NGEN-DC (NG-RAN E-UTRA-NR Dual Connectivity), the secondary node provides NR access, and the primary node provides E-UTRA access; in NE-DC (NR-E-UTRA Dual Connectivity), the primary node provides NR access. The node provides NR access, and the secondary node provides E-UTRA access; in NR-DC (NR-NR Dual Connectivity), both the primary node and the secondary node provide NR access.
在多无线电双连接中，终端设备配置有两个媒介访问控制实体：一个媒介访问控制实体用于主小区群，另一个媒介访问控制实体用于辅小区群。除PCell之外的主小区群的服务单元只能由主小区群上接收的媒介访问控制协议数据单元中的控制元素激活/停用，并且辅小区群(PSCell除外)的服务单元只能由在辅小区群上接收的媒介访问控制协议数据单元中的控制元素激活/停用。In multi-radio dual connectivity, the terminal device is configured with two medium access control entities: one medium access control entity for the primary cell group and the other medium access control entity for the secondary cell group. Serving elements of a primary cell group other than PCell can only be activated/deactivated by control elements in the medium access control protocol data unit received on the primary cell group, and serving elements of a secondary cell group (except PSCell) can only be activated/deactivated by Control element activation/deactivation in medium access control protocol data units received on the secondary cell group.
RA(Random Access，随机接入)：是指从终端设备发送随机接入前导序列开始尝试接入网络设备到与网络设备间建立起基本的信令连接之前的过程。终端设备可以在多种可能的场景下发起随机接入。例如，终端设备的状态从空闲态切换为连接态后，终端设备与网络设备建立无线链路过程时发起随机接入；或者，终端设备的状态从非激活态切换到连接态时发起随机接入；或者，终端设备在执行小区切换(Handover)过程，与新的目标小区建立无线链路过程时发起随机接入，等等。RA (Random Access, Random Access): refers to the process from when the terminal device sends a random access preamble sequence and attempts to access the network device until the basic signaling connection is established with the network device. The terminal device can initiate random access in various possible scenarios. For example, after the state of the terminal device is switched from the idle state to the connected state, random access is initiated when the terminal device establishes a wireless link with the network device; or, random access is initiated when the state of the terminal device is switched from the inactive state to the connected state ; Or, the terminal device initiates random access when performing a cell handover (Handover) procedure, establishing a wireless link with a new target cell, and so on.
本申请实施例所涉及的随机接入可以包括两步随机接入(还可以称为2-step RA)和四步随机接入(还可以称为4-step RA)，为了便于理解，下面，分别对两步随机接入和四步随机接入的过程进行详细说明。The random access involved in the embodiments of the present application may include two-step random access (also referred to as 2-step RA) and four-step random access (also referred to as 4-step RA). For ease of understanding, below, The two-step random access and four-step random access processes are described in detail respectively.

对于CFRA(Contention Free Random Access，基于非竞争的随机接入)，终端设备成功接收Msg2后，随机接入过程结束。对于CBRA(Contention Based Random Access，基于竞争的随机接入)，终端设备成功接收Msg2后，还需要继续发送Msg3和接收Msg4。For CFRA (Contention Free Random Access, non-contention-based random access), after the terminal device successfully receives Msg2, the random access process ends. For CBRA (Contention Based Random Access, competition-based random access), after the terminal device successfully receives Msg2, it needs to continue to send Msg3 and receive Msg4.
S303、终端设备向网络设备发送Msg3。S303. The terminal device sends Msg3 to the network device.
可选地，Msg3是随机接入过程中的第一个调度传输，发送净荷(payload)。Optionally, Msg3 is the first scheduled transmission in the random access process, and sends a payload.
S304、网络设备向终端设备发送Msg4。S304, the network device sends Msg4 to the terminal device.
可选地，Msg4用于指示该终端设备是否成功的接入到该网络设备。Msg4具有解决竞争冲突的作用。以初始接入为例，冲突的解决是终端设备接收Msg4的PDSCH(Physical Downlink Shared Channel，物理下行共享信道)，通过匹配物理下行共享信道中的CCCH(Common Control Channel，公共控制信道)服务数据单元(Service Data Unit，SDU)。Optionally, Msg4 is used to indicate whether the terminal device successfully accesses the network device. Msg4 has a role in resolving competition conflicts. Taking the initial access as an example, the conflict resolution is that the terminal device receives the PDSCH (Physical Downlink Shared Channel, physical downlink shared channel) of Msg4, and serves the data unit by matching the CCCH (Common Control Channel, common control channel) in the physical downlink shared channel. (Service Data Unit, SDU).
在双连接场景下，对于辅节点的服务小区，当前技术涉及主辅小区的增加和变更，即CPA(Conditional PSCell Addition，有条件主辅小区增加)和CPC(Conditional PSCell Change，有条件主辅小区变更)，接下来分别对其 进行解释说明。In the dual connectivity scenario, for the serving cell of the secondary node, the current technology involves the addition and change of the primary and secondary cells, namely CPA (Conditional PSCell Addition, conditional primary and secondary cell addition) and CPC (Conditional PSCell Change, conditional primary and secondary cells) change), which are explained separately below.

The master node sends secondary node addition request messages to T-SN1 and T-SN2 respectively. In response to the sending of the secondary node addition request, T-SN1 and T-SN2 generate a secondary node addition request acknowledgement (SN Addition Request Acknowledge) message, and the secondary node addition request acknowledgement message indicates that the termination point to be newly added for it will be added from the primary node.
