/A Shinde Koda Marutiyo IA) Reciting ``Tenpen Oni Kanbara Kite'' forward base station antenna, (6) is the relay antenna, (7) is the mobile station, (8 is the relay frequency, (9) is the dedicated frequency for communication with mobile stations, Q (I is the entire service area, (11) is the base station service area, (b) is the forward 2!il: ground-to-ground service area, and Q3 is the frequency from the base station. This is an interference area where radio waves and radio waves from the forward base station arrive and mutual interference occurs. Conventionally, the relay method using the forward base station (4) covers the entire service area as shown in Figure 1. To,
A dedicated wave (

The signal is adjusted by the e-car 1iA am/M and added to the selection section (22). The selection unit discriminates the selection signal selected and sent from the mobile station and sends it to the control unit (23), which controls the operation of the relay station radio (21) or the base station radio contact wheel based on the signal discriminated by the control unit. The demodulated audio from the two radios is added to the 0 selection unit (22) that stops the radio, and is mixed here, but the selection signal disables one of the radios and there is no demodulated output, so it is not transmitted. The voice added to the handset (22) is from the wireless station that was first selected by the mobile station, thereby eliminating interference.
