Abstract:
An operation method of a terminal in a communication system may comprise: receiving, from a base station, basis preamble information and linear combination information; generating a superposed preamble by using the basis preamble information and the linear combination information; transmitting, to the base station, a first message including the generated superposed preamble; and receiving, from the base station, a second message that is a response signal for the first message.
