Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for an AP. The AP determines a time duration associated with a validity of a first broadcast TWT parameter set associated with a broadcast TWT schedule identified by a first ID. The AP generates the first broadcast TWT parameter set to identify the determined time duration. The first broadcast TWT parameter set includes at least four bits identifying the determined time duration. The AP transmits a management frame including the generated first broadcast TWT parameter set. The time duration may indicate a number of intervals for which the first broadcast TWT parameter set is valid. Each interval of the intervals may be a beacon interval corresponding to a beacon frame, or may be a DTIM interval corresponding to a beacon frame that includes a DTIM.

Abstract: This disclosure generally relates to systems, devices, apparatuses, and methods for providing adaptive discovery timing between wireless devices. A channel is identified for use by a wireless communication device. One or more channel conditions associated with the channel are determined. The system selects a value for a minimum wait time from multiple possible minimum time values based on the one or more channel conditions. In one example, the minimum wait time may represent the amount of time that the wireless communication device will wait before sending a probe request on the channel. In another example, the selected minimum wait time may represent the amount of time that the wireless communication device will remain on the channel after sending the probe request on the channel.

Abstract: This disclosure describes techniques for operating a client device to communicate with a wireless access point to validate data within a frame by comparing channel quality metrics and duration metrics to thresholds. Information received within a validity window may be treated as correctly received even if the frame fails a subsequent verification process or if reception of the frame is terminated prior to the end of the frame.

Abstract: Disclosed are systems, methods and devices for obtaining round trip time measurements for use in location based services. In particular implementations, a fine timing measurement request message wirelessly transmitted by a first transceiver device to a second transceiver device may permit additional processing features in computing or applying a signal round trip time measurement. Such a signal round trip time measurement may be used in positioning operations.
