Abstract

A channel communication device and method for a mobile communication system using transmission antenna diversity. A base station alternatively transmits signals on a common channel via at least two antennas at first and second intervals. A mobile station estimates a time relationship between the alternatively switched common channel 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 power of the signal corresponding to the second interval, and informs the base station of the selected antenna. The base station transmits a dedicated channel via the selected antenna.
