Title:
POWER SCALING FACTOR SELECTION TECHNIQUES FOR PROBABILISTICALLY SHAPED SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2024/000351
Kind Code:
A1
Abstract:
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for power scaling factor selection techniques for probabilistically shaped systems. In some aspects, communicating devices may support probabilistic amplitude shaping such that constellation points with relatively larger or smaller amplitudes are selected relatively more or less than often than they would be without shaping and may apply one or more power scaling procedures that are specifically associated with probabilistic amplitude shaping to achieve a target or expected average transmit power across a set of transmitted modulation symbols. The communicating devices may support a first power scaling procedure associated with a first power scaling factor for an initial transmission and may support a second power scaling procedure for a retransmission.
