Abstract
An access terminal () reacquires a system frame number (SFN) when a difference between a continuous counter elapsed time () and a calculated elapsed time () exceeds a threshold. The continuous counter elapsed time () is generated by a continuous counter () remaining active during a sleep state of the access terminal () and the calculated elapsed time () is based on a SFN derived from a counter value generated by a discontinuous counter () that is deactivated during the sleep state. In one aspect, the continuous counter () may be clocked by a continuous clock () during a sleep mode and the discontinuous counter () may be clocked by a faster clock () that is deactivated during the sleep mode. During reactivation after the sleep mode, the discontinuous counter () is set, at the counter set time, to a reset counter value () corresponding to an SFN indicated by the continuous counter ().
