Title:
RADIO COMMUNICATION DEVICE, RADIO COMMUNICATION METHOD, AND RADIO COMMUNICATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2007/001052
Kind Code:
A1
Abstract:
It is possible to estimate a fading speed of a mobile station and judge whether
spatial division multi-connection is appropriate without using a response
vector of the mobile station. A radio communication device includes: fading
speed estimation unit (30) for detecting a phase change amount of a weight coefficient
of an adaptive array antenna and estimating the fading speed of the radio station
according to the phase change amount of the weight coefficient; and a communication
control unit (12) for controlling to allocate a channel for spatial division
multi-connection according to the estimation.
