Abstract: A method for an electronic device includes determining, based on indicating information of an uplink pilot sequence allocated by a base station, an uplink pilot sequence, transmitting the uplink pilot sequence, and determining a change in a geographical location of the electronic device. In a case that the geographical locations of the electronic device before and after changing correspond to different cell partitions, the uplink pilot sequence is updated based on the indicating information allocated by the base station, and the updated uplink pilot sequence corresponds to the cell partition corresponding to the geographical location of the electronic device after changing. The uplink pilot sequence is for the base station estimating a channel between the base station and the electronic device, and filtering based on the geographical location of the electronic device during the channel estimation, to obtain a channel estimation result matching the electronic device.

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.
