Abstract
Abstract The power level of multicast data transmissions in a wireless communications network are controlled. Power level information is provided in a transmitted channel received by a user equipment. The user equipment measures the power level of a received signal. It compares the measured power level to the power level indicated by the power level information provided in the transmitted channel. Power level measurement information is included in a message sent by the user equipment depending on the results obtained when the power level measured by the user equipment is compared to the power level indicated by the power level information provided in the transmitted channel.
