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: An access point (AP) may operate as a master AP (AP1) to perform multi-AP coordinated beamforming (CBF). The AP1 may to initiate a first sounding sequence with one or more STAs associated with the AP1 (BSS STAs) and the one or more STAs associated with a second AP (AP2) (OBSS STAs). In these embodiments, initiation of the first sounding sequence triggers the AP2 to join the sounding sequence to initiate a second sound sequence with the BSS STAs and the OBSS STAs.

Abstract: This disclosure describes systems, methods, and devices related to multi-link operation. A device may configure a single N×N transmit (TX)/receive (RX) radio to a plurality of 1×1 TX/RX radios, where N is a positive integer. The device may monitor a first channel of a plurality of channels to determine its availability. The device may monitor a second channel of the plurality of channels to determine its availability. The device may identify a first control frame received from an access point (AP) multi-link device (MLD) on the second channel. The device may cause to send a second control frame to the AP MLD on the second channel. The device may configure back to a single N×N TX/RX radio to receive a data frame.

Abstract: Methods, apparatuses, and computer readable media for report identification and power control for ranging in a wireless network are disclosed. An apparatus of a responding station (RSTA) is disclosed, where the apparatus comprises processing circuitry configured to perform ranging with a initiating stations (ISTAs) and maintain a separate sounding dialogue token for each of the ISTAs and transmit a corresponding sounding dialogue token for a ISTA in a trigger frame for ranging and sounding or a null data packet announcement (NDPA) frame, and in a responding to initiating location measurement report. Apparatuses of RSTAs and ISTAS are disclosed that perform power control management during non-trigger-based ranging.

Abstract: This disclosure describes systems, methods, and devices related to efficient poll response frame in wireless communications. A device may cause to send a multiuser location trigger frame of subtype poll to one or more initiating station devices (ISTAs) in a multi-user trigger-based range measurement during a polling phase. The device may identify a first clear to send (CTS) frame received from a first ISTA of the one or more ISTAs during the polling phase. The device may identify a second CTS frame received from a second ISTA of the one or more ISTAs during the polling phase. The device may determine the identity of a first ISTA based on information comprised in the first CTS frame received from the first ISTA. The device may determine the identity of the second ISTA based on information comprised in the second CTS frame received from the second ISTA.
