Abstract:
1. A radio base station which performs data transmission with radio terminals under a plurality of relay stations via the plurality of relay stations respectively, comprising: a map information generation unit which allocates a radio resource including a first transmission area from a first relay station to a first radio terminal under the first relay station and a second transmission area from a second relay station to a second radio terminal under the second relay station, and generates map information indicating the allocation; and a transmission unit which transmits the map information, wherein the map information generation unit specifies a modulation and encoding method in the map information to match a modulation and encoding method of the first radio terminal to a modulation and encoding method of the second radio terminal, when the modulation and encoding method of the first radio terminal is different from the modulation and encoding method of the second radio terminal, and the first and second transmission areas are partially or completely overlapped.
