摘要： An apparatus for wireless communication includes a classification unit and an allocation unit. The classification unit classifies communication devices in a cell where the apparatus is located, the communication devices are classified into a plurality of communication device groups including a first communication device group and a second communication device group. The allocation unit allocates pilot frequency sequences in a first pilot frequency group to the first communication device group, and allocates pilot frequency sequences in a second pilot frequency group to the second communication device group. When the number of the pilot frequency sequences is insufficient, a multiplexing configuration is executed, such as communication devices in the second communication device group multiplex at least one pilot frequency sequence in the second pilot frequency group.

摘要： 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.
