Description

Control method and device of terminal equipment and storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method and apparatus for controlling a terminal device, and a storage medium.

Background

In a multi-connection scenario, it is divided into one Primary Cell group (Master Cell Group, MCG) and one to more Secondary Cell groups (Secondary Cell Group, SCG), where the Cell group on the Primary Node (Master Node, MN) side is called Primary Cell group, and is typically composed of one Primary Cell (PCell) and one Secondary Cell (SCell) (the Secondary cells are not essential items). The Cell group on the Secondary Node (SN) side may be referred to as a Secondary Cell group, and is also composed of one Primary Cell (SCell) and one Secondary Cell (SCell).

In some application scenarios, considering energy saving, a terminal device (for example, a User Equipment, UE) may set the SCG side to a deactivated state (deactivated) when the data transmission amount is small, and in the deactivated state, the UE does not monitor a physical downlink control channel (Physical Downlink Control Channel, PDCCH) on the SCG side, does not transmit an uplink physical shared channel (Physical Uplink Shared Channel, PUSCH), does not transmit data on the SCG side of the secondary cell group, and may still perform measurement and reporting of radio resource management (Radio Resource Management, RRM).

And Timing Advance (TA) is used for controlling uplink data transmission of the UE, where the TA is a system frame for transmitting uplink data by the UE, and is advanced by a certain Time compared with a corresponding downlink frame. And the timing advance time (Time Advance Timer, TAT) is a timer controlling the TA, if the TAT times out, the UE may perform a random access (Random Access Channel, RACH) procedure to obtain the TA.

In the related art, when the secondary cell group SCG is activated, the terminal device may maintain synchronization with the network in the case that the TAT of the PSCell on the SCG side is not timed out; it is also possible to cause out of step with the network due to the fast moving speed of the terminal device, etc. How to ensure stable communication between the terminal device and the network device becomes a problem to be solved.
