METHOD PERFORMED BY USER EQUIPMENT AND USER EQUIPMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18575424 titled 'METHOD PERFORMED BY USER EQUIPMENT AND USER EQUIPMENT

The present invention describes a method performed by user equipment (UE) with dual connectivity or multi-connectivity during communication with a master cell group (MCG) and a secondary cell group (SCG).

• UE receives indication information to deactivate the SCG.
• When UE receives the indication information, it performs operations such as indicating the SCG deactivation to an upper layer (RRC or RLC layer).
• UE re-establishes an RLC entity located on the SCG after receiving the indication information.
• UE instructs the RLC layer to re-establish the SCG RLC entity based on the indication information.

• • Key Features and Innovation:**

- Method for managing connectivity in user equipment with dual or multi-connectivity. - Efficient deactivation and re-establishment of RLC entities in different cell groups. - Seamless communication handover between MCG and SCG.

• • Potential Applications:**

- 5G and beyond mobile communication networks. - IoT devices with multiple connectivity options. - Network optimization and resource management in wireless communication.

• • Problems Solved:**

- Streamlining connectivity management in user equipment. - Enhancing communication efficiency in multi-connectivity scenarios. - Improving handover processes between different cell groups.

• • Benefits:**

- Enhanced user experience with smoother connectivity transitions. - Optimal resource utilization in wireless networks. - Reduced latency and improved network performance.

• • Commercial Applications:**

Original Abstract Submitted

Provided in the present invention is a method performed by user equipment, being a method performed by the user equipment (UE) configured with dual connectivity or multi-connectivity during communication with a master cell group (MCG) and a secondary cell group (SCG), comprising the following steps: the UE receiving indication information to deactivate the SCG; when the UE receives the indication information to deactivate the SCG, performing at least one of the following operations: indicating the SCG deactivation indication information to an upper layer, wherein the upper layer is an RRC layer or an RLC layer; in the RLC layer or the RRC layer, on the basis of the indication information or after receiving the indication information, the UE re-establishing an RLC entity, wherein the RLC entity is an RLC entity that is located on the SCG, i.e., an SCG RLC entity; and in the RRC layer, on the basis of the indication information or after receiving the indication information, the UE instructing the RLC layer to re-establish the SCG RLC entity.
