    • Apparatuses may stay synchronized with a network via a beacon signal transmitted at a set interval. Communication-related activities may be planned around instances when beacon signals are expected, which may also be known as a target beacon transmission time (TBTT). Scanning opportunities, which are periods of time during which apparatuses may perform passive scanning, may be planned based on an interfere multiple of a network beacon signal interval. Apparatuses may, upon realizing a scanning opportunity, opt either to utilize the scanning opportunity or to participate in network beaconing. In example scenarios where apparatuses opt to utilize scanning opportunities, apparatuses may prepare a network information message and then enter a passive scanning mode. Apparatuses may remain in the passive scanning mode for the duration of the scanning opportunity, reacting when messages are received from devices outside of the network by transmitting the network information message.
    • 设备可以经由以设定的间隔发送的信标信号与网络保持同步。 可以在期望信标信号的情况下围绕通信相关活动,这也可以被称为目标信标传输时间(TBTT)。 可以基于网络信标信号间隔的干扰倍数来规划扫描机会,这些时间段是设备可以执行被动扫描的时间段。 在实现扫描机会时,设备可以选择利用扫描机会或参与网络信标。 在设备选择利用扫描机会的示例场景中,设备可以准备网络信息消息,然后进入被动扫描模式。 在扫描机会的持续时间内,设备可以保持处于被动扫描模式,当通过发送网络信息消息从网络外部的设备接收消息时,反应。
