摘要： Provided is a mobile communication system capable of eliminating the use of a control channel for transmitting specific area information and suppressing the overhead caused by a frequency change process for a mobile station to receive the specific area information. In the mobile communication system, a relay station (20) has a coverage area (21) (specific area) and relays and transmits, in the coverage area (21), a signal received from a base station (10) to a mobile station (30). The relay station (20) adds, to the signal received from the base station (10), the offset of any of a frequency offset, a time offset, and a power offset depending on a risk indicated by risk information in the coverage area (21) (specific area) and transmits the signal after the addition of the offset to the mobile station (30) located in the coverage area (21).

摘要： A radio receiver apparatus that can effectively utilize GI to improve the reception quality. In this apparatus, a data extracting part (104) extracts a data portion of a direct wave from a signal subjected to a radio reception process by a received RF part (102). A GI extracting part (107) extracts, from the signal subjected to the radio reception process by the received RF part (102), GI having a length determined by an extracted GI length deciding part (106). The extracted GI is adjusted by a data position adjusting part (108) such that its rear end coincides with the read end of the extracted data portion. A combining part (109) combines the extracted data portion with the GI the data position of which has been adjusted. The combined signal is then supplied to a frequency axis equalizing part (110), which equalizes the signal distortions of the combined signal on the frequency axis.

摘要： A wireless communication device, e.g., a mobile station, capable of performing its communication and relay processing for another mobile station, when requested, at the same time without stopping the communication and the relay processing. In the device, an outgoing/incoming call request detection unit (106) detects an outgoing/incoming call request indicating that an outgoing call of the signal of the mobile station or an incoming call is requested from a signal inputted from an upper-layer processing unit (105). A relay request detection unit (108) detects a relay request signal indicating that an MS1 requests an MS2 for relay to a base station from a demodulated relay signal inputted from a relay signal demodulation unit (107). A communication rate determination unit (109) determines the communication rate so as to simultaneously transmit both the signal of the mobile station and the relay signal when a signal indicating that an outgoing/incoming call request is detected is inputted from the outgoing/incoming call request detection unit (106) or a signal indicating that a relay request signal is detected is inputted from the relay request detection unit (108).
