Abstract: In a dual mode Bluetooth/wireless mobile unit, the next sleep mode Bluetooth wakeup time is rescheduled to synchronize with any upcoming idle mode wireless wakeup time that will otherwise precede the Bluetooth wakeup time. The Bluetooth clock is advanced, or other reconfiguration made to the Bluetooth module, as appropriate to prevent the scanning frequency from changing during a sleep mode Bluetooth wakeup/scanning interval commencing at the resynchronized Bluetooth wakeup time.

Abstract: A service option overlay for a CDMA wireless communication in which multiple allocatable subchannels are defined on a reverse link by assigning different code phases of a give long pseudonoise (PN) code to each subchannel. The instantaneous bandwidth needs of each on-line subscriber unit are then met by dynamically allocating none, one, or multiple subchannels on an as needed basis for each network layer connection. The system efficiently provides a relatively large number of virtual physically connections between the subscriber unites and the base stations on the reverse link for extended idle periods such as when computers connected to the subscriber unites are powered on, but not presently actively sending or receiving data. These maintenance subchannels permit the base station and the subscriber units to remain in phase and time synchronization. This in turn allows fast acquisition of additional subchannels as needed by allocating new code phase subchannels. Preferably, the code phases of the new channels are assigned according to a predetermined code phase relationship with respect to the code phase of the corresponding maintenance subchannel.

Abstract: Various techniques for improving a wireless communication device are described. The techniques may include reducing power in a wireless communication device for a first sleep period and then increasing power in the wireless communication device for an intermediate wake period after the first sleep period to estimate an error of the sleep clock. The method may further include reducing power in the wireless communication device for a second sleep period after the intermediate wake period. The intermediate wake mode implemented during the intermediate period can be used to estimate the error of the sleep clock without performing one or more tasks associated with an awake mode, such as demodulation. The techniques may facilitate the effective use of low frequency low power clocks for sleep mode, even when relatively large slot cycles are defined within a slotted paging system.

Abstract translation: 描述了用于改进无线通信设备的各种技术。 这些技术可以包括在第一睡眠周期内减少无线通信设备中的功率，然后在第一睡眠周期之后的中间唤醒周期增加无线通信设备中的功率，以估计睡眠时钟的误差。 该方法还可以包括在中间唤醒周期之后的第二睡眠周期内减少无线通信设备中的功率。 在中间周期期间实现的中间唤醒模式可用于估计休眠时钟的误差，而不执行与诸如解调之类的唤醒模式相关联的一个或多个任务。 即使在时隙寻呼系统中定义相对较大的时隙周期，这些技术可以有助于有效地使用低频低功率时钟用于睡眠模式。

Abstract: A CDMA receiver terminal comprises a finger circuit for correcting the phase of inverse spread data for signals from two antennas of a base station, and the finger circuit in turn has a level measuring circuit for determining the validity of the two signals. The level measuring circuit, when determining that any of the received signals from the two antennas of the base station is invalid, stops supplying an operating clock from a clock supply circuit to a phase corrector circuit which corrects the phase of the signal determined as invalid.
