摘要:
Certain aspects of the present disclosure relate to techniques for medium reservation in the case of multi-user (MU) communications. Multiple mechanisms are supported for protecting MU transmissions, wherein appropriate control messages can be exchanged between an access point and served user stations before transmitting downlink data packets.

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 includes receiving, at a first wireless device from a second wireless device, a signal (SIG) unit including a first field. The method also includes determining whether the first field has a particular value that is indicative of a zero-length payload and decoding the SIG unit based at least in part on the determination.
