Abstract  Abstract

A method of configuring downlink timings and transmitting a random access response message is provided for a random access procedure in a Long Term Evolution (LTE) system supporting carrier aggregation. 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.

A random access procedure control method and apparatus is provided for controlling a random access procedure efficiently in a mobile communication system supporting carrier aggregation. The method for controlling random access procedure of a terminal in a wireless communication system having a primary cell and at least one secondary cell includes initiating a random access procedure in the primary cell and the at least one secondary cells detecting a random access failure of a terminal performing the random access procedure determining whether the random access failure is detected in the primary cell or the at least one secondary cell and determining whether to continue the random access procedure according to a result of the determining of whether the random access failure is detected.
