Abstract: Methods, apparatuses, and computer readable media include an apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a legacy preamble of a physical layer (PHY) protocol data unit (PPDU), determine whether the legacy preamble comprises an indication that the PPDU is an extremely-high throughput (EHT) PPDU, and in response to the determination indicating the PPDU is the EHT PPDU, decode the EHT PPDU. Some embodiments determine a spatial stream resource allocation based on a row of a spatial configuration table, a row of a frequency resource unit table, a number of stations, and location of the station relative to the number of stations in user fields of an EHT-signal (SIG) field. To accommodate 16 spatial streams, some embodiments extend the length of the packet extension field, extend signaling of a number of spatial streams, and/or extend a number of EHT-SIG symbols.

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.
