ABSTRACT:
It is an object of the invention to provide an antenna selection method for use in a radio communication apparatus in which there is no downlink data loss which occurs due to an antenna selection operation. In a portable telephone set of the CDMA communication system, an antenna selection operation is performed in accordance with the received signal power at each of a plurality of antennas, when the communication with the base station is interrupted. As one example, the antenna selection operation is performed in response to a change of channel between the portable telephone set and the base station. Also, as another example, the antenna selection operation is performed in response to a stop of a transmitting operation in the portable telephone set.
