FRAME PROTECTION IN WIRELESS COMMUNICATIONS

This abstract first appeared for US patent application 18465962 titled 'FRAME PROTECTION IN WIRELESS COMMUNICATIONS

Original Abstract Submitted

This disclosure provides methods, components, devices and systems for frame protection in wireless communications. Some aspects more specifically relate to a first wireless device (such as a STA or AP) that may transmit frames with a packet number (PN) that has a time-based portion and a counter value. In some examples, the time-based portion may include a truncated timing synchronization function (TSF) value that indicates a time at which the frame was transmitted from the first wireless device, and the counter value may be incremented for each frame that is transmitted with a same truncated TSF value. A second wireless device may receive the frame and compare the truncated TSF with a current local time based on a truncated local TSF. The second wireless device may process the frame or discard the frame based on the comparison.
