Abstract
A communication device includes a processing circuit, the processing circuit being configured as: mapping a first information bit part used for a receiving end to a corresponding channel based on a pre-set mapping rule so as to execute spatial modulation with respect to the first information bit part of the receiving end; allocating a transmission power to the receiving end; and controlling the transmission power allocated through a mapped channel to transmit a second information bit part used for the receiving end. In the case of the first information bit parts used for multiple receiving ends being the same, the channels mapped for multiple receiving ends are the same. The multi-user spatial modulation performs spatial modulation for multiple receiving ends at the same time through a multiplexing channel of the transmitting end, improving the additional modulation order and the data transmission rate which can be obtained by each receiving end.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a divisional of U.S. application Ser. No. 16 / 323,588, filed Feb. 6, 2019, which is based on PCT filing PCT / CN2017 / 106971, filed Oct. 20, 2017, which claims priority to CN 201610934492.0, filed Oct. 25, 2016, the entire contents of each are incorporated herein by reference.TECHNICAL FIELD[0002]The present disclosure generally relates to transmission techniques in wireless communications, and more particularly to multi-user spatial modulation techniques in wireless communications.BACKGROUND ART[0003]Multiple-Input Multiple-Output (MIMO) transmission systems can provide multiplexing gain, diversity gain, and antenna gain. Therefore, the technology of MIMO has been applied in many recent communication standards, such as IEEE 402.11n, IEEE 402.16, and 3GPP Long-Term Evolution (LTE). However, there exist bottlenecks in the technology of MIMO in terms of higher complexity and increased hardware cost.[0004]In order to a...
