Abstract: A wireless user equipment (UE) may employ any of various mechanisms for reporting signal quality measurements to a wireless network. The UE may impose a time delay between measurement and reporting, based on a delay parameter K. The UE may average measurements obtained at different measurement instances. The UE may employ any of various schemes for prioritizing transmission of one type of report over another, when temporal collisions occur between different types of report. The UE may employ a differential report that includes a state for indicating that a beam is not workable. The UE may employ a beam index that includes a state for indicating an invalid beam. A base station may receive a signal quality report and determine workability of a beam, e.g., by triggering a report of channel state information.

Abstract: A first communication device receives a null data packet (NDP) transmitted by a second communication device as part of a multi-user beamforming training transmission sequence. The NDP includes a set of one or more training signals that allow the first communication device to estimate a communication channel from the second communication device to the first communication device. The first communication device generates, based on the set of one or more training signals included in the NDP received from the second communication device, an aggregate media access control protocol data unit (A-MPDU) to include a plurality of fragments of beamforming training information for the second communication device. No single fragment among the plurality of fragments includes an entirety of the beamforming training information. The first communication device transmits the A-MPDU to the second communication device in a single physical layer (PHY) data unit and as part of a multi-user transmission.

Abstract: A first communication device generates a PHY preamble of a PHY data unit to include a first orthogonal frequency division multiplexing (OFDM) symbol corresponding to a legacy signal field. The legacy signal field includes i) a length subfield, and ii) a rate subfield. The length subfield and the rate subfield indicate a duration of the PHY data unit, and the legacy signal field is formatted according to a legacy second communication protocol.

The first communication device sets the length subfield of the legacy signal field to a length value such that a remainder value resulting from dividing the length value by three, indicates that the PHY data unit conforms to the first communication protocol.

Abstract: A communication device determines, in connection with a prior uplink multi-user (UL MU) communication in which the communication device participated, whether the communication device is to use one or more first channel access parameters, or one or more second channel access parameters for accessing a communication medium for a single user (SU) transmission by the communication device, where using the one or more first channel access parameters is associated with a greater probability of obtaining access to the communication medium as compared to using the one or more second channel access parameters. Depending on the determination made, the communication device uses the one or more first channel access parameters, or the one or more second channel access parameters to attempt to access the communication medium. In response to accessing the communication medium, the communication device transmits the SU transmission via the communication medium.
