Method and device for selecting and allocating transmission beam index having priority

A transmission/reception method of a terminal in a wireless communication system capable of forming a plurality of beams comprising:

• measuring reference signals regarding the plurality of beams;
• transmitting, to a base station, index information regarding at least one transmission beam which is selected from among the plurality of beams, based on preset priority;
• and
• receiving, from the base station, a schedule of a beam corresponding to one item of the index information regarding at least one transmission beam.

A base station configured to perform transmission/reception in a wireless communication system capable of forming a plurality of beams comprising:

• a communication unit for performing data communication with a terminal;
• and
• a controller for controlling the communication unit to:
• transmit a reference signal using at least one transmission beam, to the terminal;
• receive index information regarding at least one transmission beam from the terminal;
• and schedule a beam corresponding to one item of the index information for the terminal, from among the index information regarding at least one transmission beam,
• wherein the index information is index information regarding the at least one transmission beam that the terminal selects from the plurality of beams, based on preset priorities of the plurality of beams.
