METHOD AND APPARATUS FOR ACQUIRING UPLINK SYNCHRONIZATION IN WIRELESS COMMUNICATION SYSTEM |
摘要 |
<p>The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for acquiring uplink synchronization in a terminal having a plurality of cells in a carrier aggregation-based wireless communication system and an apparatus therefor, the method comprising the steps of: transmitting a random access preamble on a first cell; receiving a random access response message including an uplink timing adjustment value for the first cell after transmitting the random access preamble; and performing uplink transmission in the first cell by using the uplink timing adjustment value, wherein a transmission time point of the random access preamble is given based on a specific time point related to a second cell.</p> |
