Abstract: Disclosed are methods, devices, and computer readable storage mediums for encoding and decoding messages for fast link adaptation. In one aspect, a method of a high efficiency (HE) station (STA) (HE STA) includes encoding an aggregated control subfield of a high throughput (HT) Control field to signal one or more of: a request to use dual carrier modulation (DCM), a request to use a particular resource unit, an uplink (UL) power headroom indication, and an indication that the HE STA is using a minimum transmit power for a current modulation and coding scheme (MCS). The method also includes configuring the HE STA to transmit a HE-PPDU including the HT control field.

Abstract: The disclosure provides some embodiments for securing long training field (LTF) sequence. A responding station (RSTA) configures a location management report (LMR) frame. The LMR frame is configured to include an LMR in respect of a previous measurement, and data to be used to generate a null data packet (NDP) for a current measurement that is to be performed following the previous measurement. The RSTA further encrypts the LMR frame using protected management frames (PMF) scheme, and transmits the encrypted LMR frame to an initiating station (ISTA) for generating an LTF sequence for the current measurement. In response to receiving an NDP announcement (NDPA) and an NDP for the current measurement from the ISTA, the RSTA generates an NDP for the current measurement based on the NDPA and the data using CCMP, and transmits the NDP to the ISTA.

Abstract: Methods, apparatuses, computer readable media for beamforming smoothing and indication in a wireless network are disclosed. An apparatus of a wireless device comprising processing circuitry is disclosed. The processing circuitry is configured to decode a null data packet (NDP). The processing circuitry is further configured to determine beamforming vectors or matrixes from a channel matrix estimate from the NDP, and smooth the beamforming vectors or matrixes. The processing circuitry is further configured to configure the station to transmit feedback, the feedback including the smooth beamforming vectors or matrixes, and decode a downlink (DL) physical layer convergence procedure (PLCP) protocol data unit (PPDU)(DL PPDU) from the access point where the DL PPDU beamformed based on the smooth beamforming vectors or matrixes.

Abstract: This disclosure describes systems, methods, and devices related to using enhanced high efficiency (HE) frames. A device may determine a high efficiency signal-B (HE-SIG-B) field for a high efficiency (HE) frame, the HE-SIG-B field comprising a common information field and a user information field. The device may determine a data portion of the HE frame, wherein the data portion includes one or more resource units (RUs) with a size equal to a number of tones. The device may determine a first resource allocation subfield and a second resource allocation subfield of the common information field based at least in part on the number of tones. The device may cause to send the HE frame.

Abstract: This disclosure describes systems, methods, and devices related to uplink location measurement report (LMR) feedback. A device may perform availability window negotiation during a negotiation phase of a location determination associated with a first initiating device of one or more initiating devices. The device may determine a status of a first LMR associated with the first initiating device. The device may cause to send a polling request to one more initiating devices during a first availability window. The device may identify a polling response from at least one of the one or more initiating devices. The device may perform one or more sounding measurements with the at least one of the one or more initiating devices during a measurement phase. The device may cause to send a trigger frame to the at least one of the one or more initiating devices.
