WIRELESS BASE STATION, USER TERMINALS, AND WIRELESS COMMUNICATION METHOD

Title:

WIRELESS BASE STATION, USER TERMINALS, AND WIRELESS COMMUNICATION METHOD

Document Type and Number:

WIPO Patent Application WO/2014/162819

Kind Code:

A1

Abstract:

In order to enable link adaptation that is suitable for a wireless communication system of the future, this wireless base station is provided with: an encoder that encodes downstream data for each of a plurality of user terminals; a modulator that modulates the downstream data for each of the plurality of user terminals; and a transmitter that multiplexes the downstream data for each of the plurality of user terminals, on a sub-band-by-sub-band basis, and transmits the downstream data using transmission power assigned to each of the plurality of user terminals, for each sub-band.
