Title:
WIRELESS COMMUNICATION DEVICE AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/056462
Kind Code:
A1
Abstract:
In the present invention, obtained is a wireless communication device with which an allocation scheme for transmission symbols can be selected on the basis of the state of a transmission path to and from a terminal. The invention is provided with: a channel estimation unit 18 for estimating a transmission path factor between a terminal intended for communication and respective sub-arrays 9; a resource scheduler unit 19 for generating mapping information and transmission weight information according to spatial multiplexing and frequency multiplexing, on the basis of the transmission path factor, and selecting and outputting the mapping information and transmission weight information according to either of the multiplexing schemes; an OFDM mapper unit 12 for mapping transmission symbols onto a frequency axis on the basis of the mapping information from the resource scheduler unit 19; and a precoder unit 13 for performing a weighting computation with respect to a signal that has been mapped at the OFDM mapper unit 12, on the basis of the transmission weight information from the resource scheduler unit 19.
