Abstract:
1. An apparatus for determining transmit power of an uplink frame at a subscriber station in a mobile communication system, the apparatus comprising: a receive power measurement unit for measuring receive power of signals received from a base station; a transmit power controller for determining the transmit power of the uplink frame from the receive power measured by the receive power measurement unit and information related to receptions of an uplink frame, which is received from the base station, wherein the information is based on a dedicated ACK/NACK received from the base station; and a transmission radio frequency processor for performing radio processing so that the uplink frame is transmitted according to the transmit power determined by the transmit power controller, wherein an increase of the transmit power of the uplink frame is determined by, Offset where the Offset
