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.
摘要翻译：一般来说，一方面，本公开描述了一种方法，其包括选择在多无线电平台（MRP）中的第一无线电的通信开始与MRP中的第二无线电的通信的开始之间的偏移。同步第一个无线电和第二个无线电的时钟来保持偏移。基于第一无线电和第二无线电的配置以及所选择的偏移来确定第二无线电通信内的安全区。安全区域是使处于固定位置的第一无线电的接收操作与第二无线电的发送操作和处于固定位置的第一无线电的发送操作和第二无线电的接收操作之间的冲突最小化的位置。

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： 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.

摘要： Systems and methods provide for controlling contention in a wireless network device. The systems and methods transmit a packet on a wireless network. If the transmission is not successful, then a contention window parameter is adjusted according to a fast backoff operation. If the packet transmission was successful and the current value of the contention window parameter is less than a threshold value then the contention window parameter is decreased according to a contention avoidance operation. If the packet transmission is successful and the current value of the contention window parameter is greater than the threshold value then the contention window parameter is decreased according to a slow start operation.
