Abstract
In a closed-loop wireless communication system (300), channel-side information—such as CQI information, rank adaptation information or MIMO codebook selection information—is fed back to the transmitter (310) in response to a start message (301) using a configurable or default time period or window by having the receiver (320) automatically terminate feedback upon expiration of the time period/window. The receiver (330) may continue or interrupt the feedback upon receipt of appropriate messaging (e.g., 306) from the transmitter (310).
