Abstract

The invention provides an uplink synchronization handling method, user equipment and a base station. The uplink synchronization handling method comprises the following steps: an uplink synchronization indication message sent by the base station is revived, wherein the uplink synchronization indication message carries the identification information of one or more newly configured CCs (Component Carriers); if the information that the newly configured CCs belong to a CC group different from that of CCs used at prevent is acquired according to the identification information of the CCs, uplink synchronization is performed to the newly configured CCs, wherein the CC group comprises one or more CCs which share the same TA (Time Advanced). According to the invention, the UE (User Equipment) can achieve uplink synchronization with the newly configured CCs when the base station needs to configure new CCs for the UE or CCs (or a CC) used by the UE at present are needed to be replaced with the newly configured CCs.

Description

technical field [0001] The present invention relates to the communication field, in particular to an uplink synchronization processing method, user equipment and a base station. Background technique [0002] A Long Term Evolved-Advanced (LTE-A for short) system needs to support a wider bandwidth than an LTE system, so multiple carriers can be aggregated. The so-called carrier aggregation is to aggregate multiple component carriers (hereinafter referred to as CC) into a carrier with a bandwidth higher than that of the LTE system, so as to support high-speed data rates. [0003] In the prior art, when a user equipment (User Equipment, hereinafter referred to as: UE) uses multiple CCs, in some scenarios, the timing advance (Time Advanced, hereinafter referred to as: TA value) of each CC is different . For example, when the base station configures different CCs on different repeaters, or CCs of different frequencies pass through different scattering paths, the TA values ​​of d...
