1. A method of performing beamforming in a base station, the method comprising:
- receiving random access channel signals transmitted in one or more transmit beams from a terminal, using one or more receive beams;
determining at least one best transmit beam from the one or more transmit beams and at least one best receive beam from the one or more receive beams; and
transmitting information about the best transmit beam and the best receive beam to the terminal.

Abstract
A method of performing beamforming in a base station is provided. The method includes receiving random access channel signals transmitted in one or more transmit beams from a terminal, using one or more receive beams, determining at least one best transmit beam from the one or more transmit beams and at least one best receive beam from the one or more receive beams, and transmitting information about the best transmit beam and the best receive beam to the terminal.
