WIPO Patent Application WO/2011/132262
Kind Code:
A1
Abstract:
A transmission-side mobile terminal (101) is provided with: a transmission unit (103) wherein array intervals for an array antenna (102) can be changed by switching and which transmits a pilot signal using a selected array based on a correlation value between a plurality of antennas; and an RS transmission number determination unit (107) which selects from a plurality of array antennas (102) an array antenna (102) for transmitting the pilot signal, based on the correlation value, and generates this antenna selection information. The transmission unit (103) transmits the antenna selection information to a reception-side base station device (110) and also transmits the pilot signal by using the selected array antenna (102).
