Constellation distortion indication for single carrier waveform digital post distortion

Abstract:

Methods, systems, and devices for wireless communication are described. A communication device, such as a user equipment (UE) may receive control signaling (e.g., a downlink control information (DCI), a radio resource control (RRC) message, a medium access control-control element (MAC-CE)) including an indication of a set of constellation points for a set of constellation distortion points. The set of constellation distortion points may be of a constellation distribution associated with a modulation scheme (e.g., a quadrature amplitude modulation (QAM), an amplitude and phase-shift keying (APSK)). The UE may perform a digital post distortion operation based on the set of constellation points for the set of constellation distortion points of the constellation distribution, and decode the wireless communication based on performing of the digital post distortion operation.
