Method for reducing power consumption in bluetooth and CDMA modes of operation

摘要

Techniques are provided for synchronizing a wakeup schedule for a first module and a wakeup schedule for a CDMA module in a wireless mobile unit operable in a synchronous communication system. In one embodiment, a next CDMA wakeup time is determined. A new wakeup time for the first module can then be synchronized to a next CDMA wakeup time when a next CDMA wakeup time is earlier than a next wakeup time for the first module

1. A method for synchronizing a wakeup schedule for a first module and a wakeup schedule for a second module in a wireless mobile unit operable in a synchronous communication system, comprising:
determining a first set of wakeup intervals for the first module within a predetermined time period; determining a second set of wakeup intervals for the second module within the predetermined time period, wherein the first set includes a number of wakeup intervals different from the corresponding number of the second set of wakeup intervals; determining a time difference between a current time and a next scheduled wakeup time of the second set of wakeup intervals; setting a next scheduled wakeup time of the first set of wakeup intervals equal to the current time plus the time difference; and providing the next wakeup time of the first set of wakeup intervals to the first module and the next wakeup time of the second set of wakeup intervals to the second module to substantially synchronize one of the wakeup intervals from the first set to another of the wakeup intervals from the second set within the predetermined time period.
