Patent ID: 8594049

Claim:
A wireless communication system comprising a base station, wherein: said base station performs scheduling for determining a resource block allocated to a mobile station, and determines a downlink transmission parameter based on a reception quality reported from said mobile station; said base station determines a transmission parameter by a predetermined first method for determining a transmission parameter when an identical resource block as a resource block allocated to any mobile station is allocated in an area adjacent to an area to which said mobile station is connecting, said base station determines a transmission parameter by a second method for determining a transmission parameter which selects a transmission parameter having a transmitting efficiency equal to or greater than that by said first method for determining a transmission parameter when an identical resource block as a resource block allocated to any mobile station is not allocated in an area adjacent to an area to which said mobile station is connecting, said mobile station comprises a unit for measuring a received power of a reference symbol from said adjacent area and a received power of reference symbols from other areas and reports said two received powers or a ratio of said two received powers to said base station, and said base station calculates a reception quality with removal of a reception quality deterioration amount due to an interference to said adjacent area by using a ratio of a received power of a reference symbol from said adjacent area and a received power of reference symbols from other areas, and determines the transmission parameter when the identical resource block as the resource block allocated to said mobile station is not allocated in the area adjacent to the area to which said mobile station is connecting.
