Abstract: Dynamic puncturing in a wireless local area network (WLAN) supporting 320 MHz bandwidths is disclosed. In one example, a method includes a first station (STA1) transmitting a null data packet announcement (NDPA) frame including an indicator of an orthogonal frequency division multiple access (OFDMA) subchannel puncturing over a wireless medium and subsequently transmitting a null data packet (NDP) having a U-SIG field specifying an OFDMA puncturing pattern. The NDPA may indicate that the subsequent NDP, which preferably occupies an 80 MHz channel, includes the OFDMA puncturing pattern in its U-SIG field. The method may further include transmitting a beamforming report poll (BFRP) soliciting measurement by the receiving station (STA2) on active resources, e.g., subchannels which have not been punctured.

Abstract: A sensing receiver may be configured for wireless local area network (WLAN) sensing, The sensing receiver may be configured to receive, from a sensing transmitter, a packet, perform measurements on the received packet, and prepare a sensing measurement report, which may comprise at least a measurement report control field and a measurement report field. A measurement type dependent parameters subfield of the measurement report control field may be based on a measurement type. The sensing receiver may be configured to send, to the sensing transmitter, the sensing measurement report. Contents of the measurement report field may be based on the measurement type. The measurement type may comprise at least one of: a channel state information (CSI) type, a channel impulse response (CIR) type, or a directional multi-gigabit (DMG)/enhanced DMG (EDM) type. The packet may be a null data packet (NDP) or a physical layer protocol data unit (PPDU).

Abstract: A method performed by a first station (STA) may compromise: receiving, from an access point (AP) that has an established transmission opportunity (TXOP) with a second STA, a multi-user request-to-send (MU-RTS) transmission opportunity (TXOP) sharing (TXS) trigger frame, wherein the MU-RTS TXS trigger frame includes: (i) an indication that the AP is sharing the TXOP established with the second STA with the first STA, and (ii) an indication of a duration of the shared TXOP; and transmitting, in response to the MU-RTS TXS trigger frame, one or more uplink (UL) frames within the duration of the shared TXOP indicated by the MU-RTS TXS trigger frame.

Abstract: Systems and methods are described for interference awareness in wireless communication systems. A wireless station (STA) may detect an interference event comprising a transmission that will interfere or is interfering with a communication session of the STA with a second device, such as an access point (AP). The first device may transmit, to the second device, an identification of the interference event. The first device may receive, from the second device, a selection of an operation mode of a plurality of modes, transmitted responsive to receipt of the identification of the interference event. The first device may continue the communication session, with the second device, utilizing the selected operation mode.

Abstract: A federated learning (FL) and/or a distributed machine learning (ML) model sharing process may be implemented in a wireless network. An access point (AP), station (STA), or the like may provide a FL announcement message indicating that a FL or ML process is in being utilized. A STA receiving the announcement message may provide a FL/ML support frame indicating its participation in FL model sharing. The STA may comprise a local FL model executable on the STA. The STA may update its local FL model based on information in the FL announcement message. The STA may update its local FL model based on information received from other STAs in the network. The FL announcement message may comprise a schedule, and the STA may be configured to train its local FL model in accordance with the schedule. The sharing model process may be implemented in a wireless local area network.

Abstract: Methods and apparatuses for Subchannel Selective Transmission (SST) in a Wireless Local Area Network (WLAN) are provided herein. A station (STA) may receive a trigger frame from an access point (AP). The trigger frame may indicate a range of association identifiers (AIDs) and/or subchannel information. The subchannel information may identify one or more secondary subchannels for an SST. The STA may determine that the AID of the STA is within the range of AIDs indicted in the trigger frame. The STA may send feedback to the AP that indicates that the STA will monitor one or more of the secondary subchannels. The STA may receive the SST from the AP on a secondary subchannel of the one or more secondary subchannels. The STA may send an acknowledgment (ACK) to the AP on the secondary subchannel in response to receipt of the SST.

Abstract: Methods and apparatuses are described herein for configuring multiple station (multi-STA) sensing-specific feedback. For example, a sensing initiator station (STA) may transmit, to first and second sensing responder STAs, a null data packet (NDP) announcement (NDPA) frame indicating one or more sensing feedback types that the first and second sensing responder STAs are to respond. The sensing initiator STA may transmit, to the first and second sensing responder STAs, an NDP frame. The sensing initiator STA may transmit, to the first and second sensing responder STAs, a trigger frame indicating one or more resources allocated for sensing measurement reports from the first and second sensing responder STAs. The sensing initiator STA may receive, from the first and second sensing responder STAs, using the one or more resources, the sensing measurement reports determined based on the one or more sensing feedback types.

Abstract: Methods and apparatuses for channel sounding reports may be used in wireless local area network (WLAN) systems. A station (STA) may receive, from an access point (AP), a beacon frame. The STA may receive, from the AP, a null data packet (NDP) announcement (NDPA) frame including an indication of subchannels for measuring channel characteristics. The STA may receive, from the AP, an NDP frame. The STA may transmit, to the AP, a feedback report frame including channel state information (CSI) feedback, wherein the CSI feedback is based on measurements that the STA performed on the received NDP frame using the indicated subchannels for measuring channel characteristics. The beacon frame may include indications of punctured subchannel(s) and subchannel(s) that is not punctured, which may be indicated as a disabled subchannel bitmap. The subchannels for measuring channel characteristics may be equal to or a subset of the subchannel(s) that is not punctured.
