Abstract  Abstract

The invention claims a method for managing a plurality of time working at different timing advance group (TAG) method and device for use in a long term evolution (LTE) system. The method for adjusting timing of a terminal in a wireless communication system supporting carrier aggregation of at least one carrier includes transmitting a Random Access Preamble to a base station and receiving a Random Access Response with a Timing Advance Command (TAC) for commanding uplink timing adjustment from the base station wherein the Random Access Response comprises information indicating a Timing Advance Group (TAG) to which the TAC is applied. According to an exemplary embodiment of the invention is used for management of TAG of method and device is able to inform each carrier belongs to timing advance and efficiently management multi-timing advance is not needed.

A method and apparatus for managing multiple Timing Advance Groups (TAGs) operating with different timings are provided for use in a Long Term Evolution (LTE) system. The method for managing multiple TAGs at a base station of a wireless communication system supporting carrier aggregation according to an exemplary embodiment of the present invention includes categorizing a plurality of carriers into at least one TAG according to a predetermined rule assigning a TAG index to each TAG transmitting the TAG index to a terminal generating a Timing Advance Command (TAC) for synchronization and transmitting the TAC to the terminal in a random access process. The method and apparatus for managing TAGs according to exemplary embodiments of the present invention is capable of informing of the timing advance group to which each carrier belongs and managing multiple timing advance groups efficiently without signaling overhead.
