Abstract: For example, a wireless communication station (STA) may be configured to generate a plurality of encoded-modulated data streams based on a data field of a PPDU to be transmitted over a channel BW. For example, the plurality of encoded-modulated data streams may be configured based on a plurality of channel BW segments in the channel BW. For example, the plurality of encoded-modulated data streams may include a first encoded-modulated data stream according to a first Modulation and Coding Scheme (MCS) corresponding to a first channel BW segment, and a second encoded-modulated data stream according to a second MCS, e.g., different from the first MCS, corresponding to a second channel BW segment. For example the STA may be configured to transmit a plurality of transmissions based on the plurality of encoded-modulated data streams over the plurality of channel BW segments.

Abstract: An access point (AP) may be configured by processing circuitry to operate as a coordinator AP for performing BSS channel level coordination. The coordinator AP is configured to assign non-overlapping channels to one or more coordinated APs of overlapping BSSs to schedule time-sensitive traffic to help ensure bounded latency, jitter and reliability per BSS. In some embodiments, the AP may be configured for performing transmission level coordination and may initiate a coordinated transmission opportunity (TXOP) for resource assignment to control contention access among managed BSSs. To perform the BSS channel level coordination, the coordinator AP is configured to encode a multi-AP trigger frame (M-TF) to initiate the coordinated TXOP. The M-TF may be encoded to include a time-sensitive operation IE indicating how each STA is to access the channel within the coordinated TXOP.

Abstract: Embodiments of an access point (AP), station (STA) and method of communication are generally described herein. The AP may be configurable to operate as a controlling AP of a multi-AP group. The controlling AP may establish the multi-AP group by: transmitting one or more messages to advertise the multi-AP group; and exchanging signaling with one or more of the other APs of the multi-AP group. The signaling may include at least one message related to one of the other APs joining the multi-AP group. The controlling AP may establish the multi-AP group to enable usage of AP Trigger Frames (AP TFs) for coordination of resources to be used for downlink transmissions of the APs of the multi-AP group.

For example, an apparatus may include logic and circuitry configured to cause a wireless communication Access Point (AP) to allocate at least one Time Sensitive Networking (TSN) enabled (TSN-enabled) Target Wakeup Time (TWT) Service Period (SP) based on one or more timing requirements of a TSN schedule of at least one TSN stream for at least one wireless communication station (STA); to transmit a TWT scheduling message to schedule the TSN-enabled TWT SP, the TWT scheduling message including an indication that the TSN-enabled TWT SP is restricted to only TSN communications; and, during the TSN-enabled TWT SP, to communicate one or more frames of the at least one TSN stream with the at least one STA.

Abstract: Embodiments of a multi-link access point (AP) device, station (STA) and method of communication are generally described herein. The multi-link AP device may comprise multiple APs. The multi-link AP device may encode a frame for transmission by one of the APs of the multi-link AP device. The multi-link AP device may encode the frame to include signaling to enable multi-link discovery of the APs of the multi-link AP device. The multi-link AP device may encode the signaling to include: a reduced neighbor report (RNR) element that identifies the APs of the multi-link AP device, and a multiple AP element. The multiple AP element may be configurable to include: common information for the APs of the multi-link AP device, and per-AP sub-elements that include per-AP information related to the APs of the multi-link AP device.

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: Apparatuses, computer readable media, and methods for received signal strength indicator (RSSI) thresholds for transitions are disclosed. An apparatus comprising processing circuitry is disclosed, where the processing circuitry is configured to associate with a first access point (AP), the first AP being part of an extended service set (ESS), decode a frame from the first AP, the frame including an ESS report element, the ESS report element including a recommended basic service set (BSS) transition threshold within the ESS field, and decode a beacon frame from the first AP. The processing circuitry may be further configured to respond to a measured RSSI of the beacon frame being below a value indicated by the recommended BSS transition threshold within the ESS field, by initiating a transition to a second AP.
