Abstract:
In a wireless communications system, a base station includes a first number of antennas and a smaller second number of radio frequency links. A base station apparatus includes: a rough arrival angle estimation unit, which estimates a rough arrival angle pair by a second number of antennas and a second number of radio frequency links; a candidate arrival angle estimation unit, which determines a candidate arrival angle pair based on a rough arrival angle pair and beam widths determined by a first number and a second number of antennas, respectively; and a precise arrival angle determination unit, which calculates the difference between the projection component and real component for the candidate arrival angle pairs based on a training tone from the user equipment, and designates the candidate arrival angle pair with the smallest difference between those components as the precise arrival angle pair.

Claim (Index 2):
The apparatus according to  claim 1 , wherein the first number of antennas form a two-dimensional planar antenna array, and the second number of antennas form a sub array selected from the two-dimensional planar antenna array.
