Title:
移動通信システムにおける基地局装置、ユーザ装置及び方法
Document Type and Number:
Japanese Patent JP5189460
Kind Code:
B2
Abstract:
A base station apparatus includes multiple antennas including M physical antennas (#1, #3, #5, #7) of a first group and M physical antennas (#2, #4, #6, #8) of a second group; a reference signal multiplexing unit which multiplexes at least M types of reference signals (P#1-P#4) to resource blocks of a downlink signal; and a transmitting unit which wirelessly transmits the downlink signal. The M types of reference signals are multiplexed to a first resource block and a second resource block in the same arrangement pattern. The M types of reference signals (P#1-P#4) within the first resource block are transmitted from the physical antennas (#1, #3, #5, #7) of the first group. The M types of reference signals within the second resource block are transmitted from the physical antennas (#2, #4, #6, #8) of the second group.
