Claim One:
1. A method of wireless communication, comprising: determining, by a user equipment (UE), an allocation of a set of tones in a symbol for conveying data; selecting, by the UE, a subset of tones from the set of tones based on values of bits of the data; determining, by the UE, to use m-ary phase shift keying (MPSK) to modulate the data onto the selected subset of tones of the set of tones; and modulating, by the UE, the data onto the selected subset of tones based on a mapping, tones in the set of tones other than the selected subset of tones being unmodulated by the UE, wherein the mapping maps pairs of data values with a largest Hamming distance from each other to pairs of constellation points with a maximum Euclidean distance from each other, wherein the set of tones includes D tones, the MPSK has M possible signal phases, k bits of data are modulated onto the selected subset of tones, and the mapping is between 2 k possible data values and 2 k constellation points of D*M constellation points, where D is a positive integer greater than 1, k is a positive non-zero integer and M is a non-zero real number.
