US 2026/0223153 A1 · TRANSMITTER-ASSISTED HARMONIC AVOIDANCE AT WIRELESS NODES

Abstract

Methods, systems, and devices for wireless communications are described. Generally, the described techniques enable a first wireless device to suppress higher-order harmonic frequencies in a reflected signal using subcarrier allocation and one or more harmonic suppression windows in an incident signal. For example, the first wireless device may determine a resource allocation across multiple resource elements (REs) of the incident signal. Within the resource allocation, a respective harmonic suppression window may include a first symbol mapped to a first RE to be reflected to the first-order harmonic frequency of the reflected signal and multiple null symbols mapped to REs that correspond to higher-order harmonic frequencies of the reflected signal. The null symbols in the harmonic suppression window may suppress interference from the higher-order harmonic frequencies, which may enable the second wireless device to more-accurately detect the first symbol.

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 first wireless device to:
determine a resource allocation across a plurality of resource elements, wherein the resource allocation comprises a first symbol mapped to a first resource element and one or more harmonic suppression windows, wherein the first resource element is associated with an incident signal to a second wireless device and each of the one or more harmonic suppression windows comprise a plurality of null symbols mapped to resource elements corresponding to harmonics of the incident signal within a harmonic order of the first resource element;
and
transmit a first signal based at least in part on performing an inverse Fourier transform operation on the plurality of resource elements.
