APERIODIC CQI REPORTING FOR PROTECTED AND PROHIBITED SUBFRAMES IN A WIRELESS COMMUNICATION NETWORK

摘要

According to certain aspects, techniques for aperiodically reporting channel state information (CSI) on protected and unprotected resources are provided. The protected resources may include resources in which transmissions in a first cell are protected by restricting transmissions in a second cell. According to certain aspects, a request for channel quality indicator (CQI) may be sent in a first subframe, (CQI) may be measured for a second subframe having a first offset from the first subframe, and a corresponding (CQI) report sent in a third subframe having a second offset from the first subframe. According to other aspects, resource partitioning enables to indicate several CQI measurement resource sets, i.e. different sets of subframes, corresponding to different interference conditions to the UE. Then the eNB triggers independent CQI requests for the different defined sets of subframes.
