RADIO TERMINAL DEVICE, TRANSMISSION DIRECTIVITY CONTROL METHOD, AND TRANSMISSION DIRECTIVITY CONTROL PROGRAM

摘要

An adaptive array terminal (2000) includes a reception adaptive array unit (2030) extracting a reception signal from a base station by multiplying signals from respective antennas (#AN 1- #AN 2) of an array antenna by respective reception weights, a transmission adaptive array unit (2090) applying to respective antennas of the array antenna a plurality of signals generated by multiplying by a transmission signal by transmission weights to form transmission directivity, and a transmission weight calculator (2070) calculating transmission weights added with a specified constraint in accordance with designation in a reception signal.
