Abstract:

Methods and apparatuses are presented for sleep optimization based on system information block SIB scheduling. A method for invoking sleep states within user equipment (UE) is presented. The method includes decoding a broadcast control channel with a cell, determining a System Information Block (SIB) schedule associated with the cell, determining a sleep time interval based upon the SIB schedule, and placing the UE in a sleep state using the sleep time intervals. An apparatus for invoking sleep states within UE is presented. The apparatus includes logic configured to decode a broadcast control channel with a cell, logic configured to determine a SIB schedule associated with the cell, logic configured to determine a sleep time interval based upon the SIB schedule, and logic configured to place the UE in a sleep state using the sleep time intervals.

Abstract:

A particular method includes receiving first data via a first network at a device that is configured to receive the first data via the first network based on a first wireless communication subscription and is configured to receive second data via a second network based on a second wireless communication subscription. The method also includes while receiving the first data, determining that a tuneaway period associated with the second network has passed, where the tuneaway period is longer than a discontinuous reception (DRX) cycle length associated with the second network. The method further includes tuning a receiver of the device to a paging channel of the second network in response to passing of the tuneaway period.
