Patent ID: 8559378

Claim:
A method for transmission in a wireless access system, comprising: transmitting a first data stream from a base station to a first user terminal in a frequency band and a time slot of a multi-user channel at a power level using a modulation and a coding; and transmitting a second data stream from the base station to a plurality of user terminals in the multi-user channel, wherein the second data stream is transmitted in the same frequency band and time slot as the first data stream, wherein the second data stream is transmitted with at least one of the power level, modulation, and coding being different from the power level, modulation, and coding for the first data stream; wherein the different power level, modulation, and/or coding facilitate separation of said first data stream from the combined first and second data streams by the first user terminal; wherein the first data stream includes unicast information for the first user terminal and the second data stream includes broadcast or multi-cast information for the plurality of user terminals, the broadcast or multi-cast information and the unicast information forming a complete information.
