US 2026/0074820 A1 · COMPENSATION OF OUTDATED CQI FOR LINK ADAPTATION

Abstract

Use of a data-driven approach that assimilates historical signal to interference-plus noise ratio (SINR) and channel estimation data along with location-map of the cell in which base station equipment is situated to better define the relationship between SINR and the user-channel environmental map and spatio-temporal changes to it to achieve more granular, cell site-specific modeling is disclosed herein. This data-driven approach estimates SINR using variational autoencoders. Variational encoders typically consist of two sections, an encoder section and decoder section. The encoder section learns the distribution on the low-dimensional latent space over the input data samples. The decoder section is a generative model that learns the joint distribution of the latent variables and input data.

Dependent claims

Base station equipment, comprising:

at least one processor;
and
at least one memory that stores executable instructions that, when executed by the at least one processor, facilitate performance of operations, comprising:
receiving, from a user equipment of a group of user equipment, channel quality indicator data representative of a channel quality corresponding to a first defined sub-band of a group of sub-bands that is to be used in scheduling a subsequent transmission of data;
in response to determining that the channel quality corresponding to the first defined sub-band is changing at a rate of change faster than a defined transmission time interval value associated with the channel quality indicator data, using an output from a neural network process to select a modulation and coding scheme value from a pool of modulation and coding scheme values;
and
transmitting, to the group of user equipment, the modulation and coding scheme value to be used by the group of user equipment for the subsequent transmission of data.
