Title:
無線通信装置及び無線通信方法
Document Type and Number:
Japanese Patent JP4583265
Kind Code:
B2
Abstract:
The present invention provides a wireless communication device improving a communication quality by properly determining a beam transmitting direction. The wireless communication device has antennas receiving signals transmitted from a terminal respectively through a plurality of paths, a detection unit detecting each of a received timing, arrival angle information and received signal power information of each of the received signals, a delay information calculation unit obtaining delay information from the fastest received timing among the detected received timings or a start timing for a path search with respect to each of the received signals, a weighted coefficient calculation unit calculating a weighted coefficient with respect to each of the received signals based on the obtained delay information, and a determining unit determining a direction of the signal transmitted toward the terminal by using arrival angle information and the weighted coefficient.
