Abstract: The present disclosure relates 5G or pre-5G communication systems for supporting higher data transmission rate than those by LTE or other post-4G communication systems. According to an embodiment of the present disclosure, a method for allocating a resource in a communication system includes determining a beam to be used for data communication between a UE and the base station based on beam feedback information from the UE. The method also includes releasing resource allocation for a beam used previously depending on whether the determined beam is changed from the previously used beam, allocating a resource for the determined beam, and transmitting information related to the resource allocation for the determined beam to the UE.
