    摘要： Methods, systems, and devices for increasing reverse link throughput by coordination of multiple wireless systems using reverse link blanking are provided. Some embodiments involve utilizing the bandwidth of one carrier bandwidth that partially overlaps with the bandwidth of another carrier bandwidth. This overlap may create interference. Different indicators may be utilized to prompt a device, such as a mobile device, to coordinate reverse link transmission blanking on at least one of the carrier bandwidths to increase throughput for the other overlapping carrier bandwidth. For example, a base station may transmit such an indicator to the mobile device to prompt the transmission blanking. Some embodiments also include increasing transmission power for the overlapping carrier bandwidth during the transmission blanking of other carrier bandwidth. Some embodiments utilize flexible carrier bandwidths systems that may utilize portions of spectrum that may not be big enough to fit a normal bandwidth waveform.

    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： A method of transmitting a data frame is disclosed and may include transmitting a preamble, transmitting a physical layer convergence protocol (PLCP) header, and transmitting a plurality of MAC protocol data units (MPDUs). Each MPDU may be configured to reset a convolutional decoder state after each MPDU. The method may also include transmitting an MPDU aggregation header. The MPDU aggregation header may include a count of packed MPDUs, an array of offsets, an array of lengths, a frame check sequence (FCS) for the MPDU aggregation header, a group of tail bits, or a combination thereof. Further, an end of the MPDU aggregation header may be aligned to an interleaved symbol boundary.
