METHOD, DEVICE AND SYSTEM FOR DETERMINING TIMING ADVANCE GROUP

摘要

Embodiments of the present invention provide a method, a device, and a system for determining timing advance grouping, and relate to the field of communications, the method, device and system for determining timing advance grouping. The solution is: adding, by a base station (eNodeB), a component carrier (CC) for a user equipment (UE); according to obtained timing advance (TA) group information or a preset rule, determining a TA group that the added CC belongs to, where the TA group is a set of CCs that can share a TA; and sending identification information that identifies the TA group to the UE. Embodiments of the present invention are used to determine TA grouping when the eNodeB adds the CC for the UE.
