摘要:
Provided is a radio relay station which relays data transmitted and received by a radio base station a radio terminal in a radio communication system which employs the TDD scheme. The radio relay station receives data from the radio base station during a downlink subframe period and transmits data to the radio base station during an uplink subframe period. The radio relay station sets a remote side transmission period for transmitting data to the radio terminal in the uplink subframe period and sets a remote side reception period for receiving data from the radio terminal in the downlink subframe period.
