摘要： Systems and methods for communicating packets having a plurality of formats are described herein. In some aspects, a signal (SIG) field in the preamble of a packet may indicate whether an extension field, such as an extension SIG field or SIG-B field, is included in the packet. In another aspect, one or more detectors may be used to auto-detect packets formatted as one of at least two different formats based on a short training field (STF) of a received packet. In some aspects, along training field (LTF) in the preamble of a packet may indicate whether the payload is repetition coded.
摘要翻译： 这里描述了用于传送具有多种格式的分组的系统和方法。 在一些方面，分组的前导码中的信号（SIG）字段可以指示分组中是否包括诸如扩展SIG字段或SIG-B字段的扩展字段。 在另一方面，一个或多个检测器可以用于基于接收到的分组的短训练字段（STF）来自动检测被格式化为至少两种不同格式之一的分组。 在一些方面，沿着分组的前导码中的训练场（LTF）可以指示有效载荷是否被重复编码。

摘要： A method, an apparatus, and a computer program product operable in a wireless communication system are provided in which an access probe is generated for transmission to a wireless node. A first signal is generated for transmission to the wireless node. The first signal includes information corresponding to a first preferred beam pattern from the wireless node to the apparatus. A second signal is received from the wireless node including information corresponding to a second preferred beam pattern from the apparatus to the wireless node. The second preferred beam pattern is determined based on the access probe. The apparatus communicates with the wireless node using at least one of the first preferred beam pattern or the second preferred beam pattern.

摘要： In a first aspect, an aggregated packet (A-MPDU) includes packets (MPDUs) and EC-Blocks (Error Correction Blocks) containing error correction coding information. A transmitter uses a Fountain coding scheme (for example, Raptor or RaptorQ) to generate the error correction coding information from the MPDUs. If a receiver detects an error in a received MPDU, then the receiver uses the error correction coding information from the EC-Blocks to correct the error. In a second novel aspect, a determination is made as to whether a change in error rate is more likely due to collisions or to a low SNR. If the determination is that the change is due to collisions then the MCS index is adjusted to restore a target error rate, whereas if the determination is that the change is due to a low SNR then the number of EC-Blocks per A-MPDU is adjusted to restore the target error rate.

摘要： A method, an apparatus, and a computer program product operable in a wireless communication system are provided in which a first signal is generated for transmission to a wireless node to enable the wireless node to determine a first preferred beam pattern. A second preferred beam pattern is determined from a second signal received from the wireless node. The apparatus communicates with the wireless node through at least one of the first or second preferred beam pattern.
