Abstract:
A radio base station (eNB) according to the present invention includes: a determination unit (14) configured to determine an assignable OFDM symbol number indicating the number of OFDM symbols in each subcarrier assignable to a control channel in a downlink, in each subframe configured by a predetermined number of OFDM symbols, wherein the determination unit (14) is configured to calculate an OFDM symbol number corresponding to a communication status, in each subframe within a measurement interval, and to set a maximum number of the calculated OFDM symbol numbers to the assignable OFDM symbol number in each subframe within a next control interval that starts after completion of the measurement interval.
