1. A method by a user equipment (UE) in a communication system, the method comprising:
receiving, from a base station, information on a change rate of a timing advance (TA) or a frequency offset;
identifying the timing advance or the frequency offset for an uplink transmission based on the information on the change rate of the timing advance or the frequency offset; and
transmitting the uplink transmission to the base station by applying the identified timing advance or frequency offset,
wherein the information on the change rate of the timing advance or the frequency offset includes information on a period and a time to which the change rate is applied, and
wherein the timing advance for the uplink transmission is identified based on a first value commonly applied to UEs located within the same beam in determining the timing advance, and the commonly applied first value is received from the base station through system information.
