Methods, apparatus, and systems for configurable modulation in wireless communications

Abstract

The present disclosure relates to configurable modulation in wireless communications. Constellation set signaling and constellation selection signaling are communicated in a wireless communication network. The constellation set signaling is associated with modulation of data using each constellation in a constellation set that includes multiple constellations. The constellation selection signaling is indicative of one of the multiple constellations of the constellation set that is to be used in modulation of data for transmission in the wireless communication network. Data that is modulated using the one of the multiple constellations is also communicated in the wireless communication network.
