METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING PREAMBLE OF RANDOM ACCESS CHANNEL IN BROADBAND WIRELESS COMMUNICATION SYSTEM

摘要

A method and an apparatus for transceiving the preamble of a reverse access channel in a broadband wireless communication system are provided to extend more the maximum cell coverage of the reverse access channel and transmit the preamble or signature of the reverse access channel longer according to a cell coverage. A method for transceiving the preamble of a reverse access channel comprises the following steps of: setting the length of the preamble(TP1(610)) longer than that of a sub frame(601); setting a first guard time(TG1(611)), at which the preamble is not transmitted, within a time range longer than the round transmission delay time of the sub frame; and transmitting the preamble, in which the first guard time is set, through the reverse access channel.
