RADIO COMMUNICATION SYSTEM, RADIO COMMUNICATION METHOD, BASE STATION DEVICE, AND TERMINAL DEVICE

摘要

A base station apparatus performs a radio communication with a terminal apparatus using a spatial division multiplex access method in a downlink. The base station apparatus includes a simultaneous connection information generation section that generates a simultaneous connection information data sequence, which includes a pilot sequence number concerning a number of a pilot signal assigned to another terminal apparatus. The base station apparatus also includes a multiplexing section that multiplexes a signal of the generated simultaneous connection information data sequence with a dedicated data signal which indicates data to be transmitted to the terminal apparatus. The base station apparatus further includes a transmission section that transmits, to the terminal apparatus, the multiplexed signal which includes the simultaneous connection information data sequence, and transmits, to the terminal apparatus, a unique pilot signal which is different from the aforementioned pilot signal assigned to the another terminal apparatus.
