Claim:
1. An apparatus for use in a communication system that is coupled to a first mobile terminal via a first communication channel and a second mobile terminal via a second communication channel, the first mobile terminal is directed to receive a 2 m1′ -ary signal constellation and the second mobile terminal is directed to receive a 2 m2′ -ary signal constellation, the first communication channel supports a 2 m1 -ary signal constellation, the second communication channel supports a 2 m2 -ary signal constellation, wherein m1, m2, m1′ and m2′ comprise respective variables that are each positive rational numbers and wherein m1′≦m1, m2′≦m2, and m1<m2, the apparatus comprising: 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: 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; 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; and 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, m1′ number of coded bits from the first encoded stream of bits and m2′ number of coded bits from the second encoded stream of bits onto a shared/multi-resolution signal constellation whose constellation points are drawn from a 2 wherein the communication system is operative to transmit control information (1) to direct the first mobile terminal to extract from a first sub-constellation portion of the 2
