Uplink synchronization processing method, user equipment, and base station
First Claim
1. An uplink synchronization processing method, comprising:
- receiving an uplink synchronization indication message, wherein the uplink synchronization indication message is carried in an RRC connection reconfiguration message, and wherein the uplink synchronization indication message carries identification information of one or multiple newly configured component carriers (CCs);
sending synchronization signaling to a base station when determining that uplink synchronization needs to be executed on all or a part of the one or multiple newly configured CCs corresponding to the identification information;
receiving a time advanced (TA) adjusting message from the base station; and
applying a TA value carried in the TA adjusting message to a CC on which the uplink synchronization needs to be executed.

Abstract
An uplink synchronization processing method, a User Equipment (UE), and a base station are provided. The method includes: receiving a component carrier (CC) uplink synchronization indication message sent by a base station, where the uplink synchronization indication message carries identification information of one or multiple newly configured CCs; sending synchronization signaling to the base station when determining that the uplink synchronization needs to be executed on all or a part of the one or multiple newly configured CCs corresponding to the identification information; and receiving a time advanced (TA) adjusting message that is sent by the base station according to the synchronization signaling, and applying a TA value carried in the TA adjusting message to the CC on which the uplink synchronization needs to be executed.
