Tone-phase-shift keying: a new modulation scheme for SC-FDMA
A method of wireless communication by a user equipment includes determining an allocation of a set of tones in a symbol for conveying data. The method further includes determining to use m-ary phase shift keying (MPSK) to modulate the data onto a subset of tones of the set of tones. The method further includes modulating the data onto the subset of tones based on a mapping, 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.
