Configuration method of secondary cell state, method and device for activating secondary cell, and medium

Abstract

The invention discloses an auxiliary cell state configuration method, an auxiliary cell activation method, equipment and a medium. The configuration method of the secondary cell state comprises the following steps: receiving indication information, the indication information is used for indicating the state of a secondary cell in a secondary cell group, and the indication information comprises an activated state, a deactivated state, a dormant state, a current state reservation state or a state before the secondary cell group is recovered to be deactivated; and if an instruction of activating the auxiliary cell group is received, configuring the state of the auxiliary cell in the auxiliary cell group according to the indication information. According to the invention, the network equipment sends the indication message for indicating the state of the auxiliary cell to the user equipment, and the user equipment directly configures the state of each auxiliary cell according to the indication message after receiving the instruction for activating the auxiliary cell group, so that the data transmission efficiency is improved on the basis of not generating extra signaling overhead and time delay.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method for configuring the state of a secondary cell, a method for activating the secondary cell, user equipment, network equipment, and a storage medium. Background technique [0002] In 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) NR (NewRadio, new wireless), UE (User Equipment, user equipment) air interface has three states: RRC_IDLE / RRC_INACTIVE / RRC_CONNECTED state, IDLE state UE and base station have no To connect, you only need to periodically initiate location updates, cell selection and reselection procedures, and receive paging, etc.; the CONNECTED state is connected to the network, and the network will configure UE radio bearers and physical layer configurations, including DC (Dual Connectivity) operation and CA (Carrier Aggregation, carrier aggregation) operation (controlled by the same base station), the network ...

AI Technical Summary

Problems solved by technology

However, the status of other SCells is unclear, and if there is no measurement result of the relevant SCell on the network side, blind activation will cause radio link failure, thereby affecting UE data transmission

Furthermore, currently, the activated or deactivated state of the SCell can be indicated through RRC or MAC CE, but before entering the dormant state, the SCell needs to be configured as the active state first, and then enter the dormant state through the DCI indication, which will inevitably bring certain information. overhead and delay
