Abstract
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.
