Abstract: This disclosure provides systems, methods and apparatuses, including computer programs encoded on computer storage media, for performing a ranging operation with a responder device. In one aspect, an apparatus exchanges a number of measurement frames with the responder device. The apparatus captures a number of timestamps based on the exchanged measurement frames. The apparatus estimates a carrier frequency offset between the responder device and the apparatus, and reports information indicative of the captured timestamps to the responder device.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may communicate with a plurality of stations in a basic service set (BSS) according to a target wakeup time (TWT) slot duration. The AP may identify one or more congestion or interference factors for the BSS. In some cases, the AP may identify a congestion score based at least in part on at least one of the one or more congestion factors from one or more stations that can be part of its own BSS, and an interference score based at least in part on at least one of the one or more interference factors form one or more stations that are not part of AP's BSS. In some cases, the AP may modify the TWT slot duration based at least in part on the congestion score and the interference score.

Abstract: A method of communication includes generating a traffic advertisement at a particular device. The traffic advertisement indicates availability of data to be sent by the particular device to multiple devices. The method also includes sending, from the particular device, the traffic advertisement during a paging window. The method further includes receiving an unavailable message from a first device of the multiple devices during a data transmission window that is subsequent to the paging window. The method also includes, in response to receiving the unavailable message from the first device, refraining from sending first data from the particular device to the first device during the data transmission window.

Abstract: A method of operation of a mobile device includes tuning a transceiver of the mobile device to communicate using a low-power (e.g., NAN) network and receiving a discovery message via the low-power (e.g., NAN) network. The discovery message indicates one or more network parameters associated with a wireless local area network (WLAN) that is associated with an access point. The method further includes communicating with the access point using the WLAN based on the one or more network parameters.

Abstract: This disclosure provides systems, methods and apparatuses for dynamically changing one or more operating parameters of a wireless network. In some aspects, an AP may detect the presence of an overlapping BSS having the same color as its own BSS. Upon detecting a color collision, the AP may temporarily disable color-related features (such as intra-PPDU power save, multi-NAV operation, spatial reuse, and the like) of its associated STAs. If the color collision persists beyond a threshold duration, the AP may dynamically change the color of its own BSS to a different BSS color. In some other aspects, the AP may detect the presence of an overlapping BSS having the same TBTT as its own. Upon detecting a beacon collision, the AP may expedite or delay the timing of its own TBTT so that it does not interfere or overlap with the TBTT of another BSS.

Abstract: A method of communication includes generating a traffic advertisement. The traffic advertisement indicates availability of data to be sent to multiple devices of a set of devices. The data includes first data to be sent to a first device and second data to be sent to a second device. The method also includes sending the traffic advertisement during a paging window. The method further includes receiving a first acknowledgement (ACK) during the paging window from the first device. The method also includes receiving a trigger message from the second device. The method further includes sending the first data to the first device during a data transmission window. The method also includes, in response to detecting receipt of the trigger message from the second device, sending the second data to the second device during the data transmission window without receiving a second ACK during the paging window from the second device.
