Radio Base Station, Relay Station, Radio Relay System, And Radio Relay Method
First Claim
1. A radio base station for communicating with a radio terminal via a relay station, comprising:
- a radio frame generation unit which generates a radio frame including a signal relay area including signal which the relay station transmits without performing demodulation and modulation, and a data relay area including signal which the relay station transmits after performing demodulation and modulation; and
a transmission unit which transmits the generated radio frame to the relay station.

Abstract
A radio base station for performing communication with a radio terminal via a relay station, including a radio frame generation unit which generates a radio frame including a signal relay region allocated in the relay station to transmit received data with predetermined delay from the radio terminal or the radio base station to the radio base station or the radio terminal respectively, and a data relay region allocated in the relay station to perform demodulation and decode, further encode and modulation processing for receive data and to transmit from the radio terminal or the radio base station to the radio base station or the radio terminal respectively; and a transmission unit which transmits the generated radio frame to the relay station.
