Abstract: A method of power control in a wireless communication system, wherein blocks are transmitted from a transmitter to a receiver via a wireless transport channel. The method comprises comparing a target signal quality value with a received signal quality value and providing the results of the comparing step to the transmitter to adjust transmit power based on the comparing step. The target signal quality value is set by the following steps: determining an initial target value; detecting if a data block has been received; detecting if received blocks have been successfully decoded; and decreasing the target value when pass blocks are received and increasing the target value when failed blocks are received subject to monitoring a period of inactivity on the transport channel in which no blocks are received.

Abstract: An apparatus and method of generating downlink power information for a multi-sector base transceiver site in which power can be shared between existing amplifiers includes a first step of gathering (S10) downlink power information for each sector. When the total power required by the sectors is less than the total power available from the base transceiver site, a next step includes modifying (S20) the information to pre-empt traffic loading such that a more heavily loaded sector will be disproportionately allocated more power than a less heavily loaded sector. A next step includes forwarding (S30, S40) the information to controllers of the base transceiver site. A next step includes determining a loading of each sector using thresholds to determine an overload in sectors depending on the information, wherein the power to each sector is adjusted disproportional to the degree with which the sector is loaded.
