METHOD, DEVICE AND SYSTEM FOR DETERMINING TIMING ADVANCE GROUP

摘要

A method, a device and a system for determining a Timing Advance (TA) group, belonging to the communication field, are provided. The solution is: a base station evolved Node B (eNodeB) adds a Carrier Component (CC) for a User Equipment (UE); the TA group that the added CC belongs to is determined according to the obtained TA group information or a preset rule, the TA group being the set of the CCs which can share a TA; and the identification information for identifying the TA group is sent to the UE. The solution is used for determining the TA group when the eNodeB adds the CC for the UE.
