摘要： An access terminal (102) reacquires a system frame number (SFN) when a difference between a continuous counter elapsed time (220) and a calculated elapsed time (222) exceeds a threshold. The continuous counter elapsed time (220) is generated by a continuous counter (122) remaining active during a sleep state of the access terminal (102) and the calculated elapsed time (222) is based on a SFN derived from a counter value generated by a discontinuous counter (124) that is deactivated during the sleep state. In one aspect, the continuous counter (122) may be clocked by a continuous clock (118) during a sleep mode and the discontinuous counter (124) may be clocked by a faster clock (120) that is deactivated during the sleep mode. During reactivation after the sleep mode, the discontinuous counter (120) is set, at the counter set time, to a reset counter value (126) corresponding to an SFN indicated by the continuous counter (122).

摘要： Techniques for dynamically determining a target setup time based on paging performance are described. A UE in an idle mode may be assigned paging occasions, which are specific time intervals in which the UE might receive paging messages. The UE may wake up a setup time prior to each paging occasion, perform setup tasks, detect for a paging indicator, and possibly receive a paging message. The UE may dynamically determine a target setup time for each awake interval based on paging performance. The target setup time may be (i) decreased by a down step if the paging performance is better than a first threshold or (ii) increased by an up step if the paging performance is worse than a second threshold. The target setup time may be updated in each fixed update period or whenever the paging performance is outside the first and second thresholds.
