RANDOM ACCESS METHOD AND RANDOM ACCESS RESPONSE METHOD

摘要

A random access method and a random access response method are provided to enable an MS to select a downlink resource optimized to a downlink channel status and transmit information about the downlink resource to a BS(Base Station) when the MS attempts random access, thereby increasing the transfer rate of the random access response of the BS to improve the reliability of the random access response of the BS. A random access response method comprises the following steps of: transmitting a common pilot signal(S101); receiving the index of at least one downlink resource selected on the basis of the common pilot signal from an MS(Mobile Station)(S103); and transmitting a response to the random access of the MS by using the index of at least one downlink resource(S104).
