Patent ID: 8879468

Claim:
A radio communication apparatus in a system that performs multicell coordinated transmission in a downlink, comprising: a selecting circuitry configured to select a set of mobile terminal apparatuses whose interference is cancelable from a plurality of mobile terminal apparatuses when a plurality of radio base station apparatuses perform joint scheduling using interference cancelling capability information fed back from each mobile terminal apparatus; and a scheduling circuitry configured to perform joint scheduling for the set of mobile terminal apparatuses, wherein the selecting circuitry selects the set of mobile terminal apparatuses based on an interference cancelling capability of each mobile terminal apparatus, a size of a coordination unit of the multicell coordinated transmission in the downlink is dynamically adjusted to cancel the interference, the size of the coordination unit corresponding to a number of radio base stations targeted for joint scheduling, and when the set of mobile terminal apparatuses does not meet a joint scheduling condition, the size of the coordination unit is reset and reduced by at least one.
