Patent attributes
A method of wireless communication with a first station arranged to transmit at least one transmission to be received by a plurality of second stations to provide a point to multipoint transmission. A first determining step determines in at least one of a plurality of second stations, if at least one transmission which is received at least one second station satisfies predetermined criterias. In response to information determined in said first determining step, a second determining step determines if a first station is to change a power level with which the first station transmits to the plurality of second stations in a point to multipoint transmission. A power changing step changes the power level with which said first station transmits power if the second determining step determines that the power level is to be changed.
