Abstract:
The present invention provides a methods, apparatus and systems for improving a systems-level data rate on a communications link such the orthogonal frequency division multiplexed multiple access (OFDMA) downlink used in used in WiFi and LTE cellular/wireless mobile data applications. The present invention preferably uses a form of multilevel coding and decoding known as tiled-building-block encoding/decoding. With the present invention, different receivers coupled to different parallel downlink channels with different channel qualities decode different received signal constellations at different levels of resolution. This allows the downlink of the OFDMA system to operate with a significantly higher data rate, thus eliminating existing inefficiencies in the downlink and significantly increasing system level bandwidth efficiency.

Claim (Index 1):
A method for use in a particular user device of a multiuser communication system, the method comprising:\n selectively partitioning a sequence of coded bits from a particular bit stream into a sequence of fixed length blocks of coded bits; sparsely mapping at least the sequence of fixed length blocks of coded bits into a resource block, wherein symbols of the resource block have a specified bit loading; and transmitting the resource block via an uplink channel to a receiver of a base station of the multiuser communication system, wherein the particular bit stream is one of a plurality of bit streams to be transmitted to the receiver of the base station in coordination therewith, one or more of bit streams of the plurality of bit streams are generated in other user devices apart from the particular user device, and the selective sparse mapping involves selectively not mapping bits from the particular bit stream onto certain symbol positions of the resource block.
