example 1

[0110] Assuming that the terminal is a multi-card terminal including UE and UE2, the UE is in a connected state and an SCG connection is established. In this case, if UE2 needs to occupy the resources of the terminal MR-DC secondary cell group, then, as Figure 4a As shown, the implementation process of controlling the secondary cell group may include the following processes.

[0111] (1) The UE sends the first indication information to the MN, where the first indication information carries the SCG suspension reason information, that is, the multi-card purpose.

[0112] Optionally, after sending the first indication information, the UE executes local suspension of the SCG, locally releases the SCG, or executes the SCG suspension after receiving the network response message sent by the MN.

[0113] (2) In the case of receiving the first indication information, the MN instructs the SN to perform SCG suspension.

[0114] (3) The MN performs a reconfiguration operation.

example 2

[0121] Assuming that the terminal is a multi-card terminal including UE and UE2, the UE is in a connected state and an SCG connection is established. In this case, if UE2 needs to occupy UE secondary cell group resources or capabilities, then, as Figure 4b As shown, the implementation process of controlling the secondary cell group may include the following processes.

[0122] (1) The UE sends the first indication information to the SN, where the first indication information carries the SCG suspension reason information, that is, the multi-card purpose.

[0123] Optionally, after sending the first indication information, the UE executes local suspension of the SCG, locally releases the SCG, or executes the SCG suspension after receiving the network response message sent by the MN.

[0124] (2) The SN performs SCG suspension when receiving the first indication information.

[0125] (3) The SN sends an SCG suspension completion notification to the MN.

[0126] (4) The MN perf...

Abstract

The invention discloses a method for controlling a secondary cell group, a terminal and network side equipment, and belongs to the technical field of wireless communication. The method comprises the following steps: a terminal sends first indication information, and / or sends second indication information; wherein the first indication information is used for indicating that the SCG is suspended to network side equipment, and the second indication information is used for indicating that the SCG is recovered to the network side equipment.

Description

technical field [0001] The present application belongs to the technical field of wireless communication, and specifically relates to a method, a terminal and a network side device for controlling a secondary cell group. Background technique [0002] In the fifth generation (5Generation, 5G) mobile communication system, a user equipment (User Equipment, UE, that is, a terminal) can adopt a dual connectivity (Dual Connectivity, DC) architecture, and the DC architecture can provide two network nodes ( One network node is called a master node (Master node, MN), and the other network node is called a secondary node (Secondary node, SN). Wherein, for each network node, a carrier aggregation technology (Carrier Aggregation, CA) can be used to configure a series of serving cells controlled by the network node for the UE, which is also called a cell group (cellgroup). The cell group controlled by the MN is called a master cell group (Master Cell Group, MCG), and the cell group contr...
