Artificial interference injection for channel state information reporting

摘要

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.

1. A method for improving link adaptation in a wireless communication system, the method performed at a User Equipment, UE, and comprising:
measuring interference on a set of time-frequency resources, TFREs, configured by an eNodeB; injecting at least one emulated interference signal into the measured interference to form a modified measured interference; determining a first Channel State Information, CSI, report based in part on the modified measured interference; and sending the first CSI report to the eNodeB.
