Radio communication apparatus and method |
摘要 |
A radio communication apparatus and system in a CDMA/TDD system includes a mobile station that detects received power of data received from a surrounding base station at a received power detecting circuit in switching a base station for communication while moving. When received power from a base station other than a main base station in current communication becomes higher than a predetermined level, the mobile station makes the base station a sub base station to transmit the same data as the main base station, and receives data from the main base station and the sub base station concurrently at a pair of correlators. After that, when the received power from the sub base station becomes higher than the received power from the main base station, the mobile station switches a main base station and a sub base station and transmits data to a new main base station.
