'' process and device of communication channel for a mobile communication system using antenna diversity transmission, the process for selecting, in a mobile station.A transmitting antenna in a base station in a mobile communication system using antenna diversity transmission, and.The device of the base station '' a device and process of communication channel for a mobile communication system using antenna diversity transmission.A base station alternately transmits signals on a common channel through at least two antennas in the first and second intervals.A mobile station estimates a time relationship between the common channel alternately switched and a user channel and measures the power of the received signals corresponding to the first and second intervals.The mobile station selects an antenna having stronger power by comparing the power of the signal corresponding to the first interval with the strength of the signal corresponding to the second interval.And informs the base station antenna selected. The base station transmits a dedicated channel via the selected antenna.
