摘要： A hand-off control method (FIG. 4) for suppressing reverse radio wave interference between radio access terminals and for accelerating hand-off, in which when a base station of greatest forward reception power has changed from a BTS1 to a BTS2 in a forward link, the radio access terminal (AT) alters the ID of a designated communication-destination base station to the BTS2 in an R-CQICH transmitted cyclically, and it makes a hand-off request after having increased transmission power of the R-CQICH a fixed quantity (403-406). The BTS1 does not transmit an FLAB and data. The BTS2 receives the R-CQICH (406) and succeeds in demodulation, thereby to recognize that the BTS2 has been designated as the communication-destination base station, and it transmits (407) an FLAB after execution and completion of a hand-off process. When the AT has received the FLAB (407) from the designated communication-destination base station BTS2, it transmits (408) the R-CQICH in which the communication-destination base station is designated as the BTS2, in a next R-CQICH transmission cycle, after having returned the transmission power of the R-CQICH (414).
