摘要： In a wireless network, a wireless device may dynamically estimate how long it can remain in a sleep mode without missing out on necessary opportunities to communicate within the network. In some embodiments, this estimate may be based at least partly on an estimate of how long it will take to transmit data in a transmit queue.
摘要翻译： 在无线网络中，无线设备可以动态地估计其可以保持在睡眠模式中的时间，而不会丢失在网络内进行通信的必要机会。 在一些实施例中，该估计可以至少部分地基于在发送队列中传输数据所需的时间的估计。

摘要： In a wireless network, a wireless device may dynamically estimate how long it can remain in a sleep mode without missing out on a necessary opportunities to communicate within the network. In some embodiments, this estimate may be based on a combination of things such as the amount of data still queued up for transmission, recent history on data rates, a prediction on how long it will take another device (e.g., an access point) to accumulate enough data for another transmission, and/or how long the queued-up data can wait before it becomes stale.
摘要翻译： 在无线网络中，无线设备可以动态地估计在休眠模式中可以保持多长时间，而不会丢失在网络内进行通信的必要机会。 在一些实施例中，该估计可以基于事物的组合，例如仍然排队等待传输的数据量，关于数据速率的最近历史，对另外的设备（例如，接入点）将要花费多长时间的预测 累积足够的数据用于另一个传输，和/或排队数据可以在其变得陈旧之前等待多长时间。

摘要： In general, in one aspect, the disclosure describes a method that includes selecting an offset between start of communications of a first radio in a multi-radio platform (MRP) and start of communications of a second radio in the MRP. Synchronizing clocks of the fist radio and the second radio to maintain the offset. Determining safe zones within the communications of the second radio based on configuration of the first radio and the second radio and the selected offset. The safe zones are locations that minimize conflicts between receiving operations of the first radio that are at fixed locations and transmitting operations of the second radio and transmitting operations of the first radio that are at fixed locations and receiving operations of the second radio.

摘要： Embodiments of systems and methods for Bluetooth and WiMAX coexistence are generally described herein. Other embodiments may be described and claimed. In some embodiments systems and methods are described to determine a temporal reference associated a frame, and then align another wireless frame with that temporal reference. Once aligned, transmissions and receptions in one wireless frame may be arranged to not temporally overlap with transmissions or reception the other wireless frame.
摘要翻译： 这里一般地描述用于蓝牙和WiMAX共存的系统和方法的实施例。 可以描述和要求保护其他实施例。 在一些实施例中，描述系统和方法以确定与帧相关联的时间参考，然后将另一无线帧与该时间参考对准。 一旦对准，一个无线帧中的传输和接收可以被布置为在时间上不与传输或接收另一无线帧重叠。

摘要： A network includes a TCP-in-TCP tunnel between a mobile device, which includes a TCP client and a gateway, and a TCP server, which resides in a subnet. Another gateway in the subnet receives and caches TCP packets and acknowledgments (ACKs) from the TCP-in-TCP tunnel. In response to receiving an indication from the TCP server that it has not received a cached TCP packet, the second gateway may resend the packet without relaying the indication to the TCP client, and the first gateway may send a control message instead of a complete TCP packet to the second gateway.
