MOBILE STATION DEVICE AND TRANSMISSION POWER CONTROL METHOD

摘要

A mobile station (12) which performs a handover from a base station (14-1) to a base station (14-2) calculates a propagation loss of a report control channel (S100) transmitted from the base station (14-2) as the handover destination and corrects a transmission power of the uplink ANCH for the base station (14-2) as the handover destination according to a known base station desired reception power and the calculated propagation loss (S124). The mobile station (12) may correct the transmission power of the uplink ANCH for the base station (14-2) as the handover destination according to the transmission power of the uplink signal for the base station (14-1), the propagation loss of the downlink signal transmitted from the base station (14-1) performing communication, and the propagation loss of the report control channel (S100) transmitted from the base station (14-2) as the handover destination (S124).
