Abstract: The present inventions relates to a method and a network node for controlling an output uplink power level of a mobile station and for controlling an output downlink power level of a target base station in a target cell of a mobile communications system. The method comprises receiving at the network node a message indicating that a handover of the mobile station from an originating cell to the target cell is completed; and commanding the target base station to use an initial output downlink power level and the mobile station to use an initial output uplink power level, wherein the initial output downlink power level and the initial output uplink power level are based on at least previous power control levels used a time after previous handovers were completed between the originating cell and the target cell.

Abstract: The invention discloses a method (700) for finding differences in path loss between a plurality of RF paths between a first (120, 130) and a second (120, 130) transceiver in a wireless communications system (100). During defined 5 intervals of time (SACCH1-SACCH4), only one RF path is used to transmit from one of said transceivers to the other of said transceivers, and the receiving transceiver measures the strength of the signal received during at least a number of said intervals, thus making it possible to compare signal strength and thereby path loss between different RF paths, which in turn 10 makes it possible to find imperfections in one or more of said RF paths.
