Abstract  Abstract

PURPOSE: An apparatus for controlling the power of PtM(Point to Multipoint) physical channels is provided to adaptive power-control for a PtM service. CONSTITUTION: Data are transmitted over a particular channel from a transmitter(54) to a plurality of receivers(56). The particular channel is received by a plurality of the receivers(56). Each of the receivers(56) sends power control information to the transmitter(54) on the basis of the measured reception quality and the reception quality requirements of each receiver. The transmitter(54) uses power control information from each receiver and adjusts a transmission power level of the particular channel so that if any receiver requires an increase in the transmission power level to meet that receiver quality requirement, the transmission power level is increased and if all receivers exceed their quality requirement, the transmission power level is decreased.
