Abstract
Embodiments of a communication station (STA) and method for time-of-flight (ToF) positioning in a wireless network are generally described herein. In some embodiments, an initiating station may transmit a message M1 carrying a high-throughput control (HTC) field that includes a reverse direction grant (RDG) bit. The RDG indication grants permission to a responding station to send information back to the initiating station. The message M1 may be a timing measurement action frame. An ACK frame may be received from the responding station to acknowledge receipt of the message M1. The ACK frame may optionally carry an HTC field that includes a more PPDU indication to indicate whether a PPDU (e.g., contained in message M2) is to follow the ACK frame. The message M2 may be received from the responding station and may include timing measurement information from a current and/or one or more previous ToF message exchanges.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
