Abstract: Systems, methods, and devices related to an EHT multi-AP group are described. The coordinated APs of the EHT group are synchronized to the coordinator AP using a periodic or non-periodic frame. Each coordinated AP then synchronizes STAs associated with the coordinated AP. In response to an MPDU, either triggered by a trigger frame from the coordinator AP or initiated by the STA, an ACK frame or NDP response is sent by each AP receiving the MPDU. The response to the MPDU is dependent on whether frame aggregation is used, as well as whether the trigger frame triggers transmission of MPDUs from multiple STAs.

Abstract: Methods, apparatuses, and computer readable media for a common preamble for wireless local-area networks (WLANs). An apparatus of an access point (AP) or station (STA) comprising processing circuitry configured to decode a portion of a physical layer (PHY) protocol data unit (PPDU), the first portion of the PPDU including a physical universal signal field (U-SIG), the U-SIG comprising a version independent portion and a version dependent portion, the version independent portion including a version identifier field, the version identifier field indicating a standard version of the PPDU. The processing circuitry is further configured to refrain from decoding the version dependent portion when the standard version indicates a standard version of a later generation than a standard version of the AP or STA, and otherwise decode the version dependent portion in accordance with the standard version.

Abstract: Methods, devices, and systems for retransmission of wake-up signals from a first station to a second station over a wireless network are disclosed. In some aspects, a wake-up signal is encoded for transmission to the second station. While the first station is waiting for an acknowledgment of the wake-up signal from the second station, the second station may retransmit the wake up signal and/or encode a packet for transmission to a third station. In some aspects, whether the wake-up signal is retransmitted is based in part, on at least one of whether a number of timeout events for wake-up signals transmitted to the second station exceeds a maximum timeouts threshold, whether a number of wake-up signals transmitted to the second station exceeds a maximum wake-up signals threshold; or whether a maximum predetermined elapsed time since a first wake-up signal was transmitted to the second station is exceeded.
