Abstract
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines whether a channel quality indicator (CQI) is to be reported during any one of x subframes immediately after a start of a next on-duration, an on-duration being a duration over which a downlink control channel is monitored every discontinuous reception (DRX) cycle, and x being a number of subframes used to generate a CQI report, schedules a wake-up time for reporting the CQI when the CQI is to be reported during any one of the x subframes immediately after the start of the next on-duration, and reports the CQI based on a reference subframe. The CQI may be based on a last subframe of a previous DRX cycle active time, and reported at a first subframe of the next on-duration.
