Uplink synchronization processing method, user equipment, and base station
First Claim
1. An uplink synchronization processing method, comprising:
- receiving an uplink synchronization indication message sent by a base station, wherein the uplink synchronization indication message carries identification information of one or multiple newly configured component carriers (CCs);
sending synchronization signaling to the base station when knowing 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; 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 a CC on which the uplink synchronization needs to be executed;
wherein the synchronization signaling is a dedicated preamble.

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 knowing 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.
