Abstract
A system and method for improving the link adaptation in a wireless communication system is disclosed. User Equipment (UE) forms an interference hypothesis by amending a measured interference and noise by artificially injecting, to the measured interference and noise, interference corresponding to at least one emulated interfering isotropic signal that is virtually transmitted over an associated estimated effective channel. The UE further determines at least one channel state information (CSI) report based on the interference hypothesis, and transmits the CSI report to the network.
