Abstract: An apparatus of a wireless communications device to transmit a sounding announcement frame (SAF) for use in a round-trip estimation to a receiving station, and associated method are provided. The apparatus is configured to encode an encoded field of the SAF that is one of a frame control field (FCF) or a sounding dialog token field (SDTF) of a null data packet announcement (NDPA) packet that forms the SAF to indicate to the receiving station that a communication different from a trigger frame may follow. The apparatus is also configured to configure the wireless device to transmit the NDPA packet to one or more stations.

Abstract: This disclosure describes systems, methods, and devices related to efficient poll response frame in wireless communications. A device may cause to send a multiuser location trigger frame of subtype poll to one or more initiating station devices (ISTAs) in a multi-user trigger-based range measurement during a polling phase. The device may identify a first clear to send (CTS) frame received from a first ISTA of the one or more ISTAs during the polling phase. The device may identify a second CTS frame received from a second ISTA of the one or more ISTAs during the polling phase. The device may determine the identity of a first ISTA based on information comprised in the first CTS frame received from the first ISTA. The device may determine the identity of the second ISTA based on information comprised in the second CTS frame received from the second ISTA.

Abstract: System and techniques for a multi-class Long Range Lower Power (LRLP) access point (AP) multifactor intelligent agent control are described herein. A station (STA) association at the AP is received. Here, the association includes Class Identifier (ID) information. The Class ID information encompasses a set of communication parameters. A schedule of LRLP and non-LRLP STAs with associations at the AP is maintained. A transceiver chain is modified based on the schedule and the set of communication parameters to complete a communication with the STA.
