    Abstract: Method for reducing power consumption in a multimode device is disclosed. The multimode device includes a COMM1 component and a COMM2 component. In one aspect, a COMM1 component may be a UWB component and a COMM2 component may be a CDMA component. According to a disclosed embodiment, the time for a next scheduled COMM1 wakeup process to be performed by a COMM1 module is established. Thereafter, if the next COMM1 wakeup process is scheduled to be performed before the next COMM2 wakeup process, a COMM2 wakeup process is synchronized to be performed by a COMM2 module at the same time as the next COMM1 wakeup process. Following, when the time arrives for the COMM1 module to perform the next COMM1 wakeup process, the COMM2 module also performs the COMM2 wakeup process.

    Abstract: Method for reducing power consumption in Bluetooth and CDMA modes of operation is disclosed. According to a disclosed embodiment, the time for a next scheduled CDMA wakeup process to be performed by a CDMA module is established (314). Thereafter, if the next CDMA wakeup process is scheduled to be performed before the next Bluetooth wakeup process (316), a Bluetooth wakeup process is synchronized to be performed by a Bluetooth module at the same time as the next CDMA wakeup process (320). Followilig, when the time arrives for the CDMA module to perform the next CDMA wakeup process, the Bluetooth module also performs the Bluetooth wakeup process (322).
