Abstract
The present invention provides a method for supplying unicast and multicast transmissions to a plurality of mobile devices in a wireless system. The method comprises supplying a multicast signal using a first portion of total available power, wherein the first portion of total available power is a function of a channel quality indicator associated with at least one of the mobile devices. Thereafter, a unicast signal is supplied using a second portion of total available power, wherein the second portion of total available power is a function of the first portion of total available power.
