To correct timing deviation of base stations using correction information between the base stations grasped by a radio terminal.

In this radio communication system 100 provided with a plurality of base stations 120 and the radio terminal 110 which performs radio communication with the plurality of base stations 120, it is characterized that the radio terminal 110 is provided with an interval monitoring part 310 which monitors time intervals between two adjacent time slots among a plurality of time slots and a correction request part 312 which, when the time interval of the two time slots is separated more than a prescribed tolerance from a reference value, transmits correction information including the separated time direction to each of the base stations which provide the two time slots and the base station 120 is provided with a correction receiving part 510 which receives the correction information from the radio terminal 110 and a timing correction part 512 which corrects the timing of the time slot on the basis of the correction information.
