technical field

The present disclosure relates to the field of mobile communication technologies, and in particular, to a method and apparatus for configuring SCG deactivation in a secondary cell group, and access network equipment.

Background technique

In the 5th Generation New Radio (5G NR) system of the fifth-generation mobile communication technology, in order to improve the data transmission rate, the network side can configure a secondary cell group SCG (Secondary Cell Group, Also called Slave Cell Group or Standby Cell Group) for load sharing to improve UE data transmission rate. After the network side configures the SCG for the UE, the UE will access the secondary base station (Secondary Node, SN) on the primary cell (Primary SCG Cell, PSCell) of the secondary cell group of the SCG. The network side can configure bearer transmission on the SCG for the UE, and the UE also maintains the configuration information of the primary cell group MCG (Master Cell Group, also known as Primary Cell Group or Main Cell Group or Controller Cell Group) and SCG.

The NR R17 project will introduce SCG deactivation. Among them, SCG deactivation is equivalent to SCG sleep state (dormant), SCG suspend (suspend), PSCell suspend or sleep state, PSCell deactivation state, etc. When data packets are transmitted, or when there is no data transmission on the SCG side, the SCG is suspended, the UE and the network side save the context of the SCG, and suspend some actions, for example, the UE stops monitoring the Physical Downlink Control Channel (PDCCH) on the SCG side. ), stop data transmission on the SCG side to save UE power consumption; when there is a large data flow interaction or when there is data transmission on the SCG side, quickly activate the UE's SCG to resume data transmission.

Therefore, it is necessary to provide a solution for the network side to configure SCG deactivation for the UE.
