Title:
MOBILE TERMINAL DEVICE, WIRELESS BASE STATION DEVICE, AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2010/150800
Kind Code:
A1
Abstract:
Provided is a wireless communication method capable of efficiently receiving control signals in high quality when data signals are transmitted using spatial multiplexing transmission and control signals are also transmitted in the same subframes. In this wireless communication method, at a mobile terminal device, a downlink signal containing precoding information is received, a data signal and a control signal are separated and assigned to different wireless resources, and signals in individual transmission layers are sent according to MIMO transmission on the basis of said precoding information, whereas at a wireless base station device, an uplink signal containing said data signal and said control signal is received, said signals having been sent according to said MIMO transmission, said uplink signal is separated into data signals for the individual transmission layers, and said control signal is reproduced from said uplink signal.
