Method, apparatus, and system for data transmission and processing in a wireless communication environment

An apparatus for processing data in a communication system, comprising:

• means for receiving indications of signal quality associated with a plurality of user stations;
• means for selecting a first user station and a second user station to receive data from a base station based on the indications of signal quality;
• means for constructing a first packet containing signaling data for the first user station and application data for the second user station;
• means for super-imposing a second packet upon the first packet, the second packet containing application data for the first user station;
• and
• means for transmitting the first and second packets simultaneously from the base station to the first and second user stations.

A machine-readable medium comprising instructions which, when executed by a machine, cause the machine to perform operations including:

• selecting, from a plurality of user stations, a first user station and a second user station to receive data from a base station based on quality of signals received at the first and second user stations;
• constructing a first packet containing signaling data for the first user station and application data for the second user station;
• super-imposing a second packet upon the first packet, the second packet containing application data for the first user station;
• and
• transmitting the first and second packets simultaneously from the base station to the first and second user stations.
