Abstract :
In this paper we propose how to control the uplink transmit power of a mobile station (MS) during soft handoff in order to reduce the error probability of downlink transmit power control command bit without macro diversity gain at the base station controller (BSC). The uplink transmit power control is based on uplink transmit power control commands from all base stations (BS) belonging to the active set. The proposed scheme can be applied to third generation mobile communication systems since an MS receives uplink (UL) transmit power control bits (TPCB) from its base stations and sends a downlink (DL) transmit power control bit (TPCB) to them
