Abstract:
A radio communication system includes one or more user terminals and one or more base stations that execute time division radio communication using a time division duplex (TDD) system. A radio frame is a radio communication resource used in the time division radio communication, and includes a downlink subframe that is a transmission period of a downlink signal, a special subframe including a guard period that is used neither for transmission of a downlink signal nor for transmission of an uplink signal, and an extended subframe that is used as either a transmission period of a downlink signal or a transmission period of an uplink signal, in accordance with a scheduling by the base station.
