Abstract: An access point (AP) station (STA) (AP STA) may be configured to operate as a multi-AP controller in a multi-AP network. A multi-AP group formation message is encoded for transmission to other APs in the multi-AP network. The multi-AP group formation message is encoded to notify the APs of the formation of an extremely-high throughput (EHT) multi-AP group, to designate whether an AP is a member of an EHT multi-AP group, and whether an AP can take the role of a coordinator AP or coordinated AP within the EHT multi-AP group. For multi-AP joint processing, the AP STA is further configured to encode an AP trigger frame for transmission to the APs in the multi-AP network. The AP trigger frame is to trigger physical layer (PHY) and medium-access control layer (MAC) parameter synchronization. The AP trigger frame is to trigger transmission of aggregated MAC protocol data units (A-MPDUs) by the APs that include MAC parameters and PHY parameters.

Abstract: Logic to place one or more protocol data units (PDUs) in a transmit queue for transmission. Logic to perform a directional clear channel assessment (CCA) for a first sector of a 60 gigahertz (GHz) link, the directional CCA to determine only if the first sector is busy or idle. Logic to determine the directional CCA indicates idle for the first sector. Logic to cause transmission of the first PDU to the STA via the first sector of the 60 GHz link based on the directional CCA. Logic to receive an acknowledgement (ACK) of receipt of the PDU from the STA. Logic to perform a directional CCA for a second sector of the 60 GHz link. And logic to communicate via the first sector and the second sector independently.

Abstract: This disclosure describes systems, methods, and devices related to an enhanced hybrid automatic repeat request (HARQ). A device may determine two or more HARQ medium access control (MAC) frames. The device may determine a difference between a first number of bits of a physical layer (PHY) codeword and a second number of bits of a first HARQ MAC frame of the two or more HARQ MAC frames. The device may generate, based on the difference, a third number of bits, wherein the first number of bits is equal to a sum of the second number of bits and the third number of bits. The device may generate an aggregated MAC frame comprising the first HARQ MAC frame, the third number of bits, and a second HARQ MAC frame of the two or more HARQ MAC frames. The device may send the aggregated MAC frame.
