    Abstract: This disclosure relates to methods for low latency orthogonal frequency division multiple access communication, according to some embodiments. A wireless device may determine to communicate with another wireless device on a frequency channel as a pair of wireless devices. The wireless device may coordinate with a set of wireless device pairs to share medium access on the frequency channel. The wireless device communicate with the paired wireless device on the frequency channel in a frequency division multiplexing configuration with the set of wireless device pairs.

    Abstract: Disclosed herein are system, method, and computer program product embodiments for indicating a preference to receive a single-user multiple input multiple output (SU-MIMO) or multi-user multiple input multiple output (MU-MIMO) transmission from an access point (AP). Embodiments include generating a standard action frame that contains an action field that species a preference to receive a SU-MIMO or MU-MIMO transmission from the AP. A station (STA) can transmit the generated action frame to the AP. The STA can receive an acknowledgement frame from the AP that indicates the AP is configured to use the requested transmission method. The STA can then receive data from the AP using the requested transmission method.

    Abstract: An interface circuit in an electronic device (such as an access point) may provide a targeted wake-up time (TWT) service period (SP) schedule to a recipient electronic device. During operation the interface circuit may receive a TWT setup request associated with the recipient electronic device, where the TWT setup request includes non-availability information specifying one or more times when the recipient electronic device will be unavailable. For example, the non-availability information may include one or more times when the recipient electronic device has limited ability to transmit and/or receive. The interface circuit may provide a TWT setup response for the recipient electronic device, where the TWT setup response includes information specifying the TWT SP schedule for the recipient electronic device that includes at least one of: a TWT SP start time, a TWT SP duration, or an interval between TWT SPs.

    Abstract: Embodiments of the present disclosure are directed to, among other things, improving data security with respect to data collection, verification, and authentication techniques associated with obtaining and transmitting identity information. For example, an identification credential may be received (e.g., via a short-range communications protocol such as iBeacon) by a first device from a second device. The credential may be associated with a second user of the second device. The first device may verify the credential and, if valid, an additional option to approve a secure communications channel may be presented at the first device. If the additional option is selected, a secure communications channel may be established between the first device and the second device.
