APPARATUS AND METHOD FOR PERFORMING RANDOM ACCESS IN WIRELESS COMMUNICATION SYSTEM |
摘要 |
An apparatus and method for performing a random access in a wireless communication system are provided. The method includes: transmitting a random access preamble on at least one serving cell to a base station; and receiving a random access response message including a plurality of timing advance information applied to each of the at least one serving cell and information on a serving cell to which the plurality of timing advance information is applied as a response to the random access preamble from the base station. The mobile station receives timing information for uplink synchronization through a plurality of serving cells, thereby making it possible to perform the uplink synchronization with the base station. In addition, it is possible to more efficiently configure the random access response message transmitted to the mobile station by the base station in order to perform the uplink synchronization.
