Abstract
A relay station comprising a control unit is used in order to control a transmission processing device and a reception processing device to eliminate overlap of the receiving period to receive a radio signal from the radio base station and the transmitting period to transmit a radio signal to a radio terminal under the control. Moreover, a control unit is provided to control the transmission processing device and the reception processing device to eliminate overlap of the transmitting period to transmit a radio signal to the radio base station and the reception period to receive a radio signal from the radio terminal.
Claims14
A relay station comprising:
- a transmitter;
- a receiver;
- and
- a controller configured to control the transmitter and the receiver not to allow overlap of a first receiving period for receiving radio signals from a radio base station and a first transmitting period for transmitting radio signals to a radio terminal under control of the relay station,
- wherein the controller controls the transmitter to provide a second transmitting period to transmit radio signals to the radio base station following the first transmitting period, and
- the controller determines a starting time of the first transmitting period by subtracting a length of the first transmitting period from a starting time of the second transmitting period which is instructed by the radio base station.
