<P>PROBLEM TO BE SOLVED: To efficiently transmit a reference signal to each user device located in an identical cell and having a different number of physical antennas. <P>SOLUTION: A base station device includes: a plurality of physical antennas including M physical antennas (#1, #3, #5, #7) in a first group and M physical antennas (#2, #4, #6, #8) in a second group; a reference signal multiplexing unit for multiplexing at least M types of reference signals (P#1 to P#4) in a downward signal resource block; and a transmitter for radio transmitting a downward signal. The M types of reference signals are multiplexed into a first and a second resource block with an identical layout pattern. The M types of reference signals (P#1 to P#4) in the first resource block are transmitted from the physical antennas (#1, #3, #5, #7) in the first group, whereas the M types of reference signals in the second resource block are transmitted from the physical antennas (#2, #4, #6, #8) in the second group. <P>COPYRIGHT: (C)2013,JPO&INPIT |
