Relay apparatus, terminal apparatus and relay method
First Claim
1. A relay apparatus for relaying information signals transmitted by radio at the same frequency, comprising:
- a reception section that receives a relay control signal which notifies a relay time which includes a start time at which the relay of said information signals starts and a continuation time during which relay continues for relaying said information signals before transmitting said information signals; and
a relay section that relays said information signals during the relay time notified by said relay control signal.

Abstract
A relay apparatus, terminal apparatus and relay method for relaying signals with a reduced scale of the apparatus, without temporally switching between transmission and reception and with reduced waste of time when relay is performed at the same frequency on a radio communication network on which bidirectional communication is performed. A radio reception section 202 outputs information signals to a switch 208, outputs relay control signals to a demodulation section 204 after subjecting predetermined radio reception processing. The demodulation section 204 demodulates a relay control signal. A relay control signal processing section 206 decides the possibility of relay of information signals and inquires, when the relay is possible, whether the terminal apparatus on the receiving side can receive this information signal or not. Furthermore, the relay control signal processing section 206 connects a switch 208 during the stored relay time. The switch 208 is connected only the information signals to be relayed are received under the control of a relay control section 2063.

9. A terminal apparatus used in a radio communication system in which information signals transmitted by radio are relayed at the same frequency by a relay apparatus, comprising:
-
a generation section that generates a relay control signal including information on the relay time which includes a start time at which the relay of said information signals starts and a continuation time during which relay continues for relaying said information signals; and a transmission section that transmits said relay control signal prior to said information signals, wherein said transmission section transmits said information signals during said relay time. - View Dependent Claims (10, 11, 12)

13. A relay method for a relay apparatus relaying information signals transmitted from a terminal apparatus, comprising:
-
a step of said terminal apparatus transmitting a first relay control signal to reserve a path for transmitting said information signals; a step of said relay apparatus receiving said first relay control signal; a step of deciding whether the relay operation of said information signals is possible or not during a relay time notified by said first relay control signal; a step of transmitting a second relay control signal indicating whether the relay operation is possible or not during said relay time as a result of the decision; a step of said terminal apparatus receiving said second relay control signal; a step of transmitting said information signals during said relay time when said second relay control signal indicates that the relay operation is possible; and a step of said relay apparatus relaying said information signals during said relay time.
