Channel prediction performance monitoring

Abstract

A method, apparatus, and computer program are described comprising: determining, by a terminal device, first predictions of channel state information using a first predictor; determining, by the terminal device, reference predictions of channel state information using a reference predictor; determining, by the terminal device, estimates of channel state information of the communication channel at the respective prediction occasions based at least in part on respective measurements of the communication channel at the respective prediction occasions; determining, by the terminal device, first prediction errors based on respective comparisons of the estimates of the channel state information and the first predictions of the channel state information corresponding to the respective prediction occasions; and determining, by the terminal device, reference prediction errors based on respective comparisons of the estimates of the channel state information and the reference predictions of the channel state information corresponding to the respective prediction occasions.
