    Abstract: A method an apparatus and a computer program product for wireless communication are provided in which a set of time intervals is obtained from a received radio frequency signal. A power profile is determined for a frequency spectrum segment in each time interval. A first list is used to identify frequency spectrum segments that exhibit a power or energy profile over a range of frequencies associated with a downlink channel bandwidth and a second list is used to identify frequency spectrum segments that have a total or average energy greater than a threshold energy relative to a noise floor. An absolute radio frequency channel number (ARFCN) of a wireless communication system is determined based on the frequency spectrum segments identified in the first and second lists.

    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.
