Abstract: This disclosure describes systems, methods, and devices related to scrambler initialization for multi-user (MU) clear to send (CTS) transmission. A first device may identify a MU request to send (RTS) frame received from a second device. The first device may determine an initial state of a scrambler based on the first 7 bits of a service field of the MU-RTS frame. The first device may cause first data to be scrambled, using the initial state of the scrambler, resulting in second data. The first device may cause to send a MU-CTS frame that comprises the second data to the second device.

Abstract: An interference-control based dynamic CCA scheme is described which will work in any compatible wireless system, including the 802.11 standards mentioned herein and in particular 802.11ac and 802.11ax. The interference control based dynamic CCA scheme can, for example, greatly improve overall wireless LAN system performance compared to other methods. The new scheme is based on interference control, by considering the possible interference to neighbouring devices, and improving overall system performance and inter-device “fairness” through this interference-based consideration technique.

Abstract: This disclosure describes systems, methods, and devices related to extremely high throughput (EHT) trigger based (TB) preamble. A device may receive a trigger frame from an associated access point (AP), wherein the trigger frame comprises one or more resource unit (RU) bandwidths (BWs) allocated to the device. The device may generate an EHT physical layer protocol data unit (PPDU) based on receiving the trigger frame from the access point, wherein the PPDU comprises an EHT preamble that includes a signaling (U-SIG) field. The device may encode the U-SIG field with an indication of one or more resource unit (RU) bandwidth (BW) allocations to be used for sending the PPDU to the AP, wherein the indication is a value associated with a first option of one or more options of selectable RU BWs. The device may cause to send the PPDU to the AP and an uplink data transmission direction.

Abstract: The disclosure provides techniques for a configuration of frequency domain aggregated (FA) physical layer protocol data unit (PPDU) for trigger based (TB) PPDUs. An apparatus for an access point (AP) includes a radio frequency (RF) interface; and processing circuitry coupled with the RF interface. The processing circuitry is configured to: encode a trigger frame to be transmitted via the RF interface to stations (STAs) communicatively connected with the AP, wherein the trigger frame includes signaling to indicate a configuration of frequency domain aggregated (FA) physical layer protocol data unit (PPDU) for at least two STAs; and decode an FA PPDU aggregated by composite trigger based (TB) PPDUs from the at least two STAs.

Abstract: This disclosure describes systems, and methods related to parallel transmission of high efficiency SIGNAL field in communication networks. A device may generate a high efficiency preamble in accordance with a high efficiency communication standard, the high efficiency preamble including, at least in part, one or more legacy SIGNAL fields, one or more high efficiency SIGNAL fields, and one or more channel training fields. The device may cause to send the one or more channel training fields to one or more first devices. The device may determine one or more spatial channel streams associated with at least one of the one or more first devices, the one or more spatial channel streams includes a first stream and a second stream. The device may partition the at least one of the one or more high efficiency SIGNAL fields into, at least in part, a common part and one or more user-specific parts, the one or more user-specific parts includes a first user-specific part and a second user-specific part. The device may cause to send at least one of the one or more user-specific parts using the one or more spatial channel streams.
