    摘要： When retransmitting lost packets of data to multiple devices in a wireless network, the original sequence of packets containing all the lost packets may be encoded into a smaller number of packets for the retransmission. These encoded packets may be collectively addressed to all the intended receiving devices through broadcast or multicast addressing. These encoded packets may then be selectively decoded by the receiving devices, using the successfully received previous packets as part of the decoding process. Repetitive exclusive OR algorithms may be used for encoding and decoding.

    摘要翻译： 当向无线网络中的多个设备重传丢失的数据包时，包含所有丢失分组的分组的原始序列可以被编码为较少数量的分组以进行重传。 这些编码的分组可以通过广播或多播寻址集体地寻址到所有预期的接收设备。 然后可以使用成功接收的先前分组作为解码过程的一部分，由接收设备选择性地解码这些编码分组。 重复的异或算法可用于编码和解码。

    摘要： Methods and systems suitable for negotiating air traffic trajectory modification requests received from multiple aircraft that each has trajectory parameters. The methods include transmitting from at least a first aircraft a first trajectory modification request to alter the altitude, speed and/or lateral route thereof. A first conflict assessment is then performed to determine if the first trajectory modification request poses a conflict with the altitudes, speeds and lateral routes of other aircraft. If a conflict is not identified, the first trajectory modification request is granted and the first aircraft is notified of the first trajectory modification request being granted. Alternatively, if a conflict is identified, the first trajectory modification request is not granted and the first aircraft is notified thereof. If the first trajectory modification request was not granted, the first trajectory modification request is placed in a queue, which is periodically processed to perform subsequent conflict assessments.

    摘要： Embodiments may comprise logic such as hardware and/or code to enable coexistence of high-density and low-density transmissions with a modified CSMA protocol. Embodiments include a self-CTS (self clear to send) packet transmission prior to transmission of a ready to send (RTS) signal when initiating a high density transmission amidst legacy devices. In many embodiments, the self-CTS or the RTS includes a network allocation vector (NAV) having a value for the duration of the transmission. In some embodiments, the self-CTS may include a flag or bit to indicate the Shading Transmission Starts (STS).
