1. A method performed by a terminal in a wireless communication system, the method comprising:
identifying that a scheduling request (SR) is triggered;
in case that the SR is triggered and a medium access control (MAC) entity of the terminal is configured with a logical channel (LCH)—based prioritization, identifying whether a resource for an SR transmission associated with the triggered SR overlaps with an uplink grant received in a random access response (RAR);
in case that that the resource for the SR transmission does not overlap with the uplink grant received in the RAR:
identifying whether a counter for the SR transmission is less than a threshold, and
in case that the counter for the SR transmission is less than the threshold, transmitting the SR based on the resource for the SR transmission; and
in case that the resource for the SR transmission overlaps with the uplink grant received in the RAR:
considering the SR transmission as a de-prioritized SR transmission,
considering the uplink grant received in the RAR as a prioritized uplink grant, and
transmitting an uplink signal based on the prioritized uplink grant.
