The present disclosure relates to a communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G and IoT-related technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure provides methods and apparatus for scheduling transmission resources between a user equipment and a base station. A method includes detecting a buffer status report (BSR) triggering event based on a BSR retransmission timer, identifying a highest priority logical channel (LCH) having data available for transmission in response to the detected event, identifying SR configuration information corresponding to the highest priority LCH and transmitting, to a base station, an SR based on the identified SR configuration information.
