US 12,494,959 B2 · Adaptive determination of constellation point usage probabilities

Abstract

Methods, systems, and devices for wireless communication are described. A request associated with probabilities of respective points of a constellation for communication of a set of data symbols using a channel may be received. The channel may be between a wireless device and a network entity. The probabilities may indicate respective likelihoods of the respective points being used in the communication of the set of data symbols. Signaling may be communicated in accordance with the set of probabilities of the respective points, where the set of probabilities may be adapted to characteristics of radio frequency impairments associated with the channel. The characteristics of the radio frequency impairments may be measured by a wireless device.

Dependent claims

A user equipment (UE) for wireless communication, comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
receive, from a network entity, a request associated with probabilities of respective points of a constellation for communication of a set of data symbols over a channel between the UE and the network entity, wherein the probabilities indicate respective likelihoods of the respective points being used in the communication of the set of data symbols;
and
communicate, with the network entity, signaling in accordance with a set of probabilities of the respective points, wherein the set of probabilities are adapted to characteristics of radio frequency impairments associated with the channel that are measured by the UE.
