Abstract: Methods, apparatuses, and computer readable media for channel state information for multiple access points are disclosed. Channel station information (CSI) may be coordinated for multiple access points (APs) where one AP may act as a master AP with other AP acting as slave APs. The channel station information may be based on information from null data packets received by stations from multiple-APs, which may enable a multi-AP coordinated beamforming (CBF) to be determined based on the received first CSI reports. New frame formats are disclosed that include fields for including APs. Overlapping basic service set (OBSS) stations may respond to APs that are not within their BSS. Some embodiments relate to passive range finding in a multi-AP sounding where location configuration information (LCI) changes for one of the APs.

Abstract: An access point (AP) configured for multi-AP coordinated beamforming (CBF) and multi-AP joint transmission (JT) in an Extremely High Throughput (EHT) wireless local area network (WLAN), when operating as a master AP (AP1) in a multi-AP network, is configured to encode a null data packet announcement (NDPA) frame for multi-AP channel sounding. The NDPA is configured for transmission to a second AP (AP2) and a plurality of stations (STAs) of an EHT group. The NDPA may be encoded to have an information field indicating whether a sounding sequence type is for JT channel sounding or CBF channel sounding. The NDPA may further be encoded to include fields identifying the APs participating in the channel sounding. In these embodiments, the channel sounding sequence for JT can be reused for the channel sounding on CBF.

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.

Abstract: An apparatus for a station (STA) configured for operating in a next-generation (NG) wireless local area network (WLAN) comprises the processing circuitry configured to modify probabilities of constellation points to generate a more Gaussian distribution. In these embodiments, for LDPC framing and OFDM packing, the transmitter circuitry may be configured to compute a number of output bits (bout) to be transmitted based on a number of payload bits (bin) at an output of a shaping encoder, a shaping rate (rshaping), and an overhead percent (Boverhead). A shaping gain of up to 1.53 dB may be achieved. A new shaping encoder is provided to address the issue that the number of bits is not fixed.

Abstract: This disclosure describes systems, methods, and devices related to adaptation of secure sounding signal. A device may determine a negotiated bandwidth to be used when communicating with a first station device. The device may determine a first bit stream used to generate a cyclic shift diversity (CSD) value based on the negotiated bandwidth, wherein a first number of bits is used for the first bit stream when a first negotiated bandwidth is used, and wherein a second number of bits is used for the first bit stream when a second negotiated bandwidth is used. The device may determine a second bit stream used to generate a random phase. The device may determine a secure a long training field (LTF) based on a combination of the first bit stream and the second bit stream. The device may cause to send a frame to the first station device, wherein the frame comprises the secure LTF.

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.

A device may determine one or more medium access control (MAC) protocol data unit (MPDUs) to be sent to a first station device of one or more station devices, wherein the one or more MAC protocol data units (MPDUs) comprise a first MPDU. The device may segment the first MPDU into a plurality of segments, wherein the one or more segments include a first segment and a second segment. The device may cause to send the plurality of segments to the first station device. The device may identify a feedback frame received from the first station device, wherein the feedback frame comprises error information associated with the plurality of segments. The device may cause to retransmit at least one of the plurality of segments based on the error information.
