RADIO BASE STATION AND COMMUNICATION CONTROL METHOD

摘要

An eNB1-1 employs frequency hopping that assigns a radio resource to a UE2-1 in response to switching of a frequency of an SRS from the UE2-1, and determines an MCS in a first radio resource block when a first downlink radio resource block is assigned to the UE2-1, on the basis of SINR acquired for a second downlink radio resource block having a frequency bandwidth equal to a frequency bandwidth of the first downlink radio resource and being assigned to the UE2-1 in the past.
