METHOD OF PERFORMING RANDOM ACCESS PROCEDURE IN WIRELESS COMMUNICATION SYSTEM

摘要

A random access process performing method in a wireless communication system is provided to increase reliability on message reception during a random access process, and to prevent service delay during initial connection or handover. A random access preamble randomly selected from a random access set is transmitted(S710). A random access response is received as a response for the random access preamble(S720). A connection request message is transmitted by using radio resource allocation information included in the random access response. A CQI(Channel Quality Indicator) for a downlink channel is transmitted(S730). A contention resolution message transmitted by considering the CQI is received(S740). The CQI is transmitted through a PUSCH(Physical Uplink Shared Channel).
