Abstract: The disclosure provides some embodiments for securing long training field (LTF) sequence. A responding station (RSTA) configures a location management report (LMR) frame. The LMR frame is configured to include an LMR in respect of a previous measurement, and data to be used to generate a null data packet (NDP) for a current measurement that is to be performed following the previous measurement. The RSTA further encrypts the LMR frame using protected management frames (PMF) scheme, and transmits the encrypted LMR frame to an initiating station (ISTA) for generating an LTF sequence for the current measurement. In response to receiving an NDP announcement (NDPA) and an NDP for the current measurement from the ISTA, the RSTA generates an NDP for the current measurement based on the NDPA and the data using CCMP, and transmits the NDP to the ISTA.

Abstract: In one example, a first wireless communication station (STA) may be configured to identify an estimated end of a frame transmitted from a second STA to an Access point (AP); and to transmit a transmission to the AP within a Short-Inter-Frame-Space (SIFS) beginning at the estimated end of the frame from the second STA.

In another example, an AP may be configured to process a frame from a first STA; and to process a transmission from a second STA, the transmission from the second STA received within a SIFS beginning at an end of the frame from the first STA.
