ABSTRACT:
A preamble transmission method for a wireless communication system is provided for improving the probability of successful transmission and reducing unnecessary retransmission power consumption. The preamble transmission method of the present invention calculates an initial transmission power; transmits a preamble with the initial transmission power through a random access channel; if an acknowledgement is received in response to the preamble, starts transmission of data; and if no acknowledgement is received in response to the preamble—calculates a retransmission power, and retransmits the preamble with the retransmission power.
