Abstract
A method for random access (RA) performed by a terminal in a communication system, is provided. The method includes receiving, from a base station, a first random access channel (RACH) configuration for 4-step RA, a second RACH configuration for 2-step RA, and physical uplink shared channel (PUSCH) configuration, in case that a type of the RA is the 2-step RA, identifying an RA occasion for the 2-step RA; identifying a valid PUSCH resource based on the PUSCH configuration, wherein the valid PUSCH resource is a PUSCH resource not overlapping with the RA occasion for the 2-step RA, and in case that a random access preamble in the RA occasion for the 2-step RA is not mapped to the valid PUSCH resource, transmitting, to the base station, the random access preamble in the RA occasion for the 2-step RA.
