Abstract: An extremely high throughput (EHT) station (STA) configured for trigger based (TB) transmission may decode an trigger frame (TF) received from an access point (AP). The TF may include an assignment of resources comprising one or more 20 MHz channels. The EHT STA may determine which of the one or more assigned channels are available for transmission and which of the allocated channels are unavailable when the EHT STA is assigned more than one 20 MHz channel. The EHT STA may encode a EHT TB PPDU in response to the trigger frame. The EHT TB PPDU may be encoded to include an EHT preamble followed by a data field. The EHT preamble may be encoded to indicate channel availability. The EHT STA may generate signaling to cause the EHT STA to transmit the encoded EHT TB PPDU only on the assigned channels that have been determined to be available.

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: For example, a wireless communication device may be configured to disable a per-antenna Cyclic Shift Diversity (CSD) insertion for a Long Training Field (LTF) of a Physical Layer (PHY) Protocol Data Unit (PPDU), for example, based on a determination that the PPDU is to be configured for a predefined type of channel-sounding-based measurement. For example, the per-antenna CSD insertion may include insertion of a CSD between a plurality of transmit chains of the wireless communication device. For example, the wireless communication device may be configured to transmit the LTF of the PPDU via the plurality of transmit chains with the per-antenna CSD insertion disabled.
