Abstract:
The present invention provides a methods, apparatus and systems for improving a systems-level data rate on a communications link such theorthogonal 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):
An apparatus configured for use in an arrangement where the apparatus is coupled to a first mobile terminal via a first communication channel and to a second mobile terminal via a second communication channel, information is transmitted to the first mobile terminal via a 2 m1\u2032 -ary signal constellation and to the second mobile terminal via a 2 m2\u2032 -ary signal constellation, the first communication channel supports a 2 m1 -ary signal constellation, and the second communication channel supports a 2 m2 -ary signal constellation, wherein m1, m2, m1\u2032 and m2\u2032 comprise respective variables that are each positive rational numbers, and wherein m1\u2032\u2264m1, m2\u2032\u2264m2, and m1\u2264m2, the apparatus comprising:\n at least one processor coupled to a memory which holds instructions to be executed by the at least one processor, wherein the instructions cause the at least one processor to perform the following actions:\n receive a first stream of bits associated with the first mobile terminal, and encode the first stream of bits to form a first encoded stream of bits; \n receive a second stream of bits associated with the second mobile terminal and encode the second stream of bits to form a second encoded stream of bits; \n receive the first encoded stream of bits and the second encoded stream of bits and form a symbol stream by mapping, during each of a plurality of symbol intervals, a first set of m1\u2032 number of coded bits from the first encoded stream of bits and a first set of m2\u2032 number of coded bits from the second encoded stream of bits onto a shared/multi-resolution signal constellation; and \n transmit control information (1) to direct the first mobile terminal to compute first receiver demodulation information for the first mobile terminal to use in a first decoder to form an estimate of the first stream of bits, and (2) to direct the second mobile terminal to compute second receiver demodulation information for the second mobile terminal to use in a second decoder to form an estimate of the second stream of bits; \n \n wherein at least one of the first encoded stream of bits and the second encoded stream of bits are encoded, at least in part, by a low density parity check (LDPC) code; and \n wherein the constellation points of the shared/multi-resolution signal constellation are drawn from a member of a group consisting of:\n a 2 m -ary underlying constellation associated with a shared/multi-resolution resource block, wherein m comprises a variable that is a positive rational number, wherein m\u2265m1\u2032+m2\u2032, and the 2 m -ary underlying constellation is selected to be equal to a predefined downlink constellation, and \n a constellation formed by adjusting a relative spacing between selected 2 m1\u2032 -ary signal subconstellations of the shared/multi-resolution signal constellation and/or between constellation points of the 2 m1\u2032 -ary signal subconstellations to meet a power requirement.
