  • Publication number: 20140120926
    Abstract: Provided is an operation method of a cellular telecommunication system for operating multiple beams. In an operation method of a base station, a beam identifier (ID) is allocated to each of the multiple beams, and a terminal reports a beam ID of a selected beam to the base station. When the operation method of the cellular telecommunication system is used, the base station can rapidly sense the entry of the terminal into a specific beam area. Even when the terminal moves between beam areas, it is possible to rapidly make a beam area change with a minimum overhead without performing random access again or performing a complex procedure such as a handover procedure.
