<p>A mobile station (60) in a CDMA cellular radio system transmits a possibly unique power control command every power control group time when the mobile station is in contact with a single base station When the mobile station (60) is in soft handoff (in communication with two or more base stations simultaneously) however, the mobile station (60) sends the same power control command for several power control group times, thus reducing the probability of receiving an erroneous power control command at a base station. The base stations (40, 50) synchronize their power levels periodically according to a predetermined number of power control command groups, resulting in more optimum base station power transmission levels, in turn resulting in a reduction in system noise and an increase in system capacity. <IMAGE></p> |
