    • Electronic devices may be provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. An electronic device may alternate between a sleep mode and a wake mode. During wake mode, the electronic device may monitor a paging channel in a wireless network for incoming paging signals. The device may use either a single antenna mode or a multiple antenna mode such as a dual antenna mode in monitoring the paging channel. In the single antenna mode, a single active antenna is used to receive paging signals. In the dual antenna mode two antennas are simultaneously used to receive paging signals. The device may choose which antenna mode to use based on signal quality measurements and history information on successfully received paging signals.
    • 可以提供包含无线通信电路的电子设备。 无线通信电路可以包括耦合到多个天线的射频收发器电路。 电子设备可以在睡眠模式和唤醒模式之间交替。 在唤醒模式期间,电子设备可以监视无线网络中的呼入寻呼信号的寻呼信道。 该设备可以使用单天线模式或多天线模式,例如双天线模式来监视寻呼信道。 在单天线模式中,单个有源天线用于接收寻呼信号。 在双天线模式中,两个天线同时用于接收寻呼信号。 设备可以基于信号质量测量和成功接收的寻呼信号的历史信息来选择要使用的天线模式。

    • Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. An electronic device may alternate between a sleep mode and a wake mode. During wake mode, the electronic device may monitor a paging channel in a wireless network for incoming paging signals. The device may use a selected one of the multiple antennas in monitoring the paging channel. If received signal quality is satisfactory, the device may maintain use of the selected one of the multiple antennas for subsequent wake period monitoring of the paging channel. If received signal quality falls below a threshold or is otherwise indicated to not be satisfactory, the device may switch to use of a different one of the multiple antennas in monitoring the paging channel. Other criteria may also be used in controlling the switching between antennas for paging channel monitoring.
    • 可以提供包含无线通信电路的电子设备。 无线通信电路可以包括耦合到多个天线的射频收发器电路。 电子设备可以在睡眠模式和唤醒模式之间交替。 在唤醒模式期间,电子设备可以监视无线网络中的呼入寻呼信号的寻呼信道。 该设备可以使用多个天线中所选择的一个来监视寻呼信道。 如果接收到的信号质量令人满意,则设备可以保持对多个天线中所选择的一个天线的使用以用于寻呼信道的随后的唤醒周期监视。 如果接收到的信号质量低于阈值或被指示为不令人满意,则在监视寻呼信道时,设备可以切换到使用多个天线中的不同的天线。 其他标准也可以用于控制用于寻呼信道监测的天线之间的切换。
