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： Systems, methods, and devices for communicating long packets are described herein. In some aspects, one or more training fields are interposed between data symbols of a data unit. The training fields may comprise a short training field (STF) and/or a long training field (LTF). The training fields may be used by a receiving device to adjust settings or parameters used for decoding the data symbols.

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.

摘要： A method includes receiving, at a first wireless device from a second wireless device, a signal (SIG) unit including a length field and an aggregation field. The length field is interpreted as a number of symbols in response to determining that the aggregation field has a first value. The length field is interpreted as a number of bytes in response to determining that the aggregation field has a second value.
摘要翻译： 一种方法包括在第一无线设备处从第二无线设备接收包括长度字段和聚合字段的信号（SIG）单元。 响应于确定聚合字段具有第一值，长度字段被解释为多个符号。 响应于确定聚合字段具有第二值，长度字段被解释为多个字节。
