A cell group on the secondary node (Secondary Node, SN) side may be called a secondary cell group, which is also composed of a primary cell (Primary SCG Cell, PSCell) and a secondary cell SCell.

In some application scenarios, considering energy saving, terminal equipment (for example, user equipment User Equipment, UE) can set the SCG side to a deactivated state when the amount of data transmission is small, and in the deactivated state , the UE does not monitor the Physical Downlink Control Channel (PDCCH) on the SCG side, does not perform uplink Physical Uplink Shared Channel (PUSCH) transmission, and does not perform data transmission on the SCG side of the secondary cell group, but still Measurement and reporting of Radio Resource Management (RRM) can be performed.

The timing advance (Time Advance, TA) is used for the control of the UE's uplink transmission data, and the timing advance TA refers to the system frame in which the UE transmits the uplink data, which is ahead of the corresponding downlink frame by a certain time. The timing advance time (Time Advance Timer, TAT) is a timer that controls the TA. If the TAT times out, the UE can perform a random access (Random Access Channel, RACH) process to obtain the TA.
