Abstract

A method of wireless communication by a user equipment includes determining an allocation of a set of tones in a symbol for communicating data. The method also includes determining to use m-ary phase shift keying (MPSK) to modulate data onto a subset of tones of the set of tones. The method also includes modulating data onto the subset of tones based on a mapping that maps pairs of data values ​​having a maximum Hamming distance to each other to pairs of constellation points having a maximum Euclidean distance to each other.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 062,132, filed October 9, 2014, entitled "TONE-PHASE-SHIFT KEYING: ANEW MODULATION SCHEME FOR SC-FDMA," and filed December 16, 2014, The benefit of US Patent Application No. 14 / 572,730, entitled "TONE-PHASE-SHIFT KEYING: A NEW MODULATION SCHEME FOR SC-FDMA," the entire contents of which are expressly incorporated herein by reference. technical field [0003] The present disclosure relates generally to wireless communications, and more particularly to signal modulation. Background technique [0004] Orthogonal Frequency Division Multiplexing (OFDM) is a popular signal modulation scheme with various advantages. One advantage is that OFDM easily supports flexible multi-user access. OFDM and Orthogonal Frequency Division Multiple Access (OFDMA) are widely used in modern wireless communication systems such as Wireless Local Area Network (WLAN), Lon...
