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.
