1. A method performed by a terminal in a communication system, the method comprising:
triggering a buffer status report (BSR);
triggering a scheduling request (SR) for the BSR;
transmitting a medium access control (MAC) protocol data unit (PDU) including the BSR, before transmission of the SR; and
determining whether to cancel the triggered SR, based on information on a priority of a logical channel corresponding to the SR and information on priorities of logical channels associated with the MAC PDU including the BSR,
wherein the triggered SR is canceled based on a determination that a highest priority among the priorities of the logical channels associated with the MAC PDU including the BSR is higher than or equal to the priority of the logical channel that has triggered the SR.
