Patent ID: 8416718

Claim:
A transmitting method of a signal on a random access channel in a wireless communication system, a terminal transmitting a cyclic prefix and a preamble on the random access channel with a set time length ahead of the end position of an uplink pilot time slot in order, and the length of the preamble being the length of two symbols without a cyclic prefix; wherein the set time length is n×Ts+Tcp, wherein n×Ts is the length of the uplink pilot time slot, Tcp is the length of the cyclic prefix, and Ts=1/30.72 us, and wherein the length of the cyclic prefix is Tcp=m×Ts−Tpre+Tds, wherein m×Ts is the length of the symbol with the cyclic prefix in the uplink pilot time slot occupied by the random access channel, Tds is the length of the largest delay extension on a multi-path channel transmitted in order under the cyclic prefix and the preamble application environment in the uplink pilot time slot, its unit is us, Tpre=4096×Ts, and Ts=1/30.72 us.
