Abstract: Densely populated wireless local area networks (WLANs) can encounter issues with processing multiple user (MU) uplink (UL) transmissions sent from many stations (STAs) simultaneously. The access points (AP) or master stations in these densely populated WLANs must manage the UL MU transmissions. To accomplish the management of the UL MU transmissions, a system for dynamically setting UL MU parameters is provided that can modify or set one or more parameters that govern how each STA is to transmit data to the AP. The parameters may be sent to one or more of the STAs in one or more transmissions and may direct how the STAs are to transmit data for at least some portion of time.

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: 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.
