Abstract:
1. A terminal equipment which performs communication with a wireless base station controlling other terminal equipments for spatial multiplexing connection by using interference cancellation capability information included in reception signals from the other terminal equipments, the terminal equipment comprising: an interference cancellation capability information data maintaining unit which maintains interference cancellation capability information data indicating capabilities for cancelling, by the terminal equipment, interference suffered by the terminal equipment due to communication from the base station device to other terminal equipments; a transmission unit which transmits the interference cancellation capability information data of the terminal equipment to the wireless base station device; a reception unit which receives a transmission signal that was transmitted from the wireless base station by a spatial multiplexing connection to the terminal equipment and the other terminal equipments that were selected by the wireless station based on the interference cancellation capability information data; wherein the interference cancellation capability information data is the number of interference signals which can be cancelled by the terminal equipment, and is indicated by a degree of antenna, and the degree of freedom of antenna is determined based on a quantity of antennas included by the terminal equipment; and wherein the selected other terminal equipments have higher degree of freedom of antenna than that of the terminal equipment.
