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： Disclosed is a method of controlling communication rates over a link within a communications system. The method includes storing packets associated with voice and data traffic in individual buffers, and determining an instantaneous number of active voice and active data traffic in the individual buffers. Furthermore, a total link bandwidth that the active voice traffic will consume during a frame interval is determined, and an available link bandwidth, for the active data traffic, remaining after the total link bandwidth is calculated. Finally, rate control is applied to fit the active data traffic in the available link bandwidth. Rate control is achieved by allowing a data session to send data at a portion of its full-rate, where the portion is determined as a function of the instantaneous load generated by all sessions carried on the link.

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.
