Title:
WIRELESS BASE STATION, USER TERMINAL AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/057655
Kind Code:
A1
Abstract:
The present invention can suppress a reduction in throughput, even when NOMA and MIMO are used in combination. A wireless base station according to one embodiment of the present invention has: a transmission unit that transmits, by a single stream or a plurality of streams, a DL signal to each of a plurality of user terminals; and a control unit that controls the DL signals transmitted to each user terminal so as to be power multiplexed and transmitted. The control unit sets, for each stream, the multiplexing power ratio of the DL signals to be power multiplexed.
