Method and apparatus for allocating resource in communication system

A method for allocating a resource in a communication system, the method comprising:

• transmitting beam feedback information including information about a beam to be used for data communication between a user equipment (UE) and a base station;
• receiving information related to resource allocation for a beam determined based on the beam feedback information depending on whether the determined beam is different from a beam previously used;
• and
• identifying a resource allocated based on the information related to the resource allocation for the determined beam.

A base station for allocating a resource in a communication system, comprising:

• a transceiver configured to transmit and receive data;
• and
• a controller configured to:
• determine a beam to be used for data communication between a user equipment (UE) and the base station based on beam feedback information from the UE;
• release resource allocation for a beam used previously depending on whether the determined beam is different from the previously used beam;
• allocate a resource for the determined beam;
• and
• transmit information related to the resource allocation for the determined beam to the UE.
