Diversity gains indicating an amount to be gained when maximal ratio combining is performed on intra-cell diversity branches are stored in a first memory, and diversity gains indicating an amount to be gained when selective combining is performed on inter-cell diversity branches are stored in a second memory. A list of pilot signals sent from a mobile station is received and examined. If the diversity branch of a pilot signal is an intra-cell diversity branch, a diversity gain is read from the first memory and summed with the power level of the pilot signal. If the diversity branch of a pilot signal is the inter-cell diversity branch, a diversity gain is read from the second memory and summed with the power level of the pilot signal. One of the diversity branches corresponding to the highest of the sums is selected and the mobile station is informed of the selected branch.
