摘要： Wireless video transmissions over a MAC layer employ various techniques to improve throughput which may negatively impact latency, such as Block-ACK and data aggregation. To improve latency while continuing to improve throughput, data packets are fenced according to application layer specifications and then transmitted. For video data, Block-ACK sequences and aggregation sequences are terminated at the end of video frames or video slices. For data aggregation, a physical layer data packet concludes at the end of a video frame or slice. The application layer can indicate to the MAC layer when such packet fencing is to occur. In use with 802.11n transmission a data flag may be used by the MAC layer to facilitate fencing.

摘要： Low-power transmitter and/or receiver devices are provided by sacrificing time and/or frequency diversity in exchange for lower power consumption. When channel conditions indicate that time and/or frequency spreading are unnecessary for transmissions, a transmitter may enter into a power-conservation mode in which transmissions are performed using a time gating scheme or a time repetition scheme. In the time gating scheme, symbols are transmitting just once, rather than a plurality of times, but with increased transmission power. In the time repetition scheme, copies of the same symbol are transmitted a plurality of times on the same frequency on different symbol transmission periods, instead of being retransmitted on different frequencies on different symbol transmission periods. Consequently, the symbol can be generated once and stored for subsequent retransmission, thereby allowing some of the transmitter/receiver chain components can be operated at a lower duty cycle or processing speed to conserve power.
摘要翻译： 通过牺牲时间和/或频率分集来提供低功率发射机和/或接收机设备，以换取更低的功耗。 当信道条件指示时间和/或频率扩展对于传输是不必要的时，发射机可以进入其中使用时间选通方案或时间重复方案执行传输的功率节约模式。 在时间选通方案中，符号只传输一次，而不是多次，但是传输功率增加。 在时间重复方案中，相同符号的副本在不同的符号传输周期上以相同频率发送多次，而不是在不同的符号传输周期上在不同的频率上重发。 因此，可以生成符号一次并存储以用于随后的重传，从而允许一些发送器/接收器链组件可以以较低的占空比或处理速度操作以节省功率。

摘要： An exemplary method for reserving medium access in an ad hoc network comprises transmitting a reservation request by a reservation owner, the reservation request identifying a reservation allocation, a reservation target, and a reservation type. The reservation type identifies exclusive use of the reservation allocation by the reservation owner and the reservation target during a reservation period. The reservation target may employ a prioritized contention access (PCA) scheme to access the reservation allocation. Alternatively, an idle portion of the reservation allocation may be subdivided into a plurality of slots including even slots and odd slots, and the reservation owner gains access to the idle portion by starting to transmit during an even slot, while the reservation target gains access to the idle portion by starting to transmit during an odd slot. In yet another embodiment, the reservation owner transmits an outgoing clear to send (CTS) communication to the reservation target to transfer ownership of the reservation allocation to the reservation target, and receives an incoming clear to send (CTS) communication from the reservation target to regain ownership of the reservation allocation.
