Abstract: In a communications system using a plurality of beams, a terminal determines a beam to be communicated with the terminal among the plurality of beams, determines one sequence among sequences allocated to the determined beam as a beam based random access preamble, and transmits the beam based random access preamble through the determined beam. In addition, if a random access response for the beam based random access preamble is not received from a base station for a set interval, the terminal determines one sequence among sequences in a cell based random access preamble collection as a cell based random access preamble and transmits the cell based random access preamble.

Abstract: Provided is a method for feeding back a channel quality indicator (CQI) by a terminal. The terminal receives, from a base station, at least one reference signal through at least one of multiple beams of the base station. The terminal measures a signal-to-interference plus noise ratio (SINR) for the at least one reference signal. The terminal determines a first level corresponding to the measured SINR among levels of a first CQI. In addition, the terminal feeds back the first CQI having the first level to the base station.
