Abstract
This radio communication method is used to perform spatial multiplexing communication between cells in the overlap cell environment. In the MU-MIMO overlap cell environment, when a null is formed between a radio base station and a radio terminal station belonging to different cells, a first set of a “call signal” and a “response signal” is used to perform mutual detection with the radio base station and the radio terminal station belonging to different cells, and then a null is formed so as not to cause interference of radio waves between the radio base station and the radio terminal station belonging to different cells. At this time, the addresses of the radio base station and the radio terminal station are used to discriminate whether the radio base station and the radio terminal station belong to the same cell or different cells.
