    Abstract: A method and apparatus may be configured to support coordinated orthogonal block-based resource allocation (COBRA) operations. An access point (AP) may be configured to indicate to a plurality of stations (STA)s that it may support COBRA. Each WTRU may be configured to indicate to the AP that it can support COBRA as well. The AP may be configured to transmit a COBRA controller information element (IE) comprising a plurality of fields to each of the WTRUs. Each WTRU may be configured to transmit a COBRA controllee IE comprising a plurality of fields. STA grouping management, group maintenance, channel access, beamforming, sounding and frequency and synchronization procedures are also described.

    Abstract: Methods and apparatuses are described herein for HARQ signaling and communications in wireless networks. For example, a method implemented in a STA comprises receiving a first MU transmission including a first set of HARQ bits, a first set of user data for STAs including the STA, a preamble including information indicating that the MU transmission includes the first set of HARQ bits, and a first set of HARQ Process IDs associated with the first set of HARQ bits; determining a subset of HARQ bits of the first set of HARQ bits; transmitting a response message indicating a reception status of the subset of HARQ bits; and receiving a second MU transmission including a second set of HARQ bits, a second set of user data for the plurality of STAs, and a second set of HARQ Process IDs associated with the second set of HARQ bits.

    Abstract: Methods, devices, and systems for resource allocation are disclosed herein. Specifically, a wireless transmit receive unit (WTRU) may measure a reference signal received power (RSRP) level and a received signal strength indicator (RSSI) value of one or more resources in each of a plurality of patterns. The WTRU may exclude, from the selection, each pattern for which at least one resource in the pattern is reserved by another WTRU and has an RSRP greater than a threshold. On a condition that at least one of the plurality of patterns is not excluded, the WTRU may select a pattern with a lowest pattern RSSI value and a one or more resources satisfying a quality of service (QoS) requirement of data of the WTRU. The WTRU may then transmit the data of the WTRU using the selected pattern.

    Abstract: A STA may comprise a receiver configured to receive, from an AP, a first polling frame addressed to a broadcast address and sent to a plurality of STAs. The first polling frame may indicate a plurality of sub-channels. The STA may further comprise a transmitter configured to transmit, to the AP, a first PPDU indicating SNR information, on one or more sub-channels of the plurality of sub-channels, a SIFS after the first polling frame is received. The transmitter may be configured to transmit the first PPDU while a second PPDU is transmitted to the AP by another STA of the plurality of STAs, wherein the second PPDU is transmitted on one or more other sub-channels of the plurality of sub-channels.

    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 are described herein for network discovery. A wireless transmit/receive unit (WTRU) may transmit, to a first access point (AP), via a Primary Connectivity Radio (PCR), a request indicating that on a condition that the WTRU is disassociated from the first AP, the WTRU will enter a wake-up radio (WUR) only discovery mode. The WTRU may receive, from the first AP, via the PCR, a management frame that has WUR discovery elements including an indication of at least one channel used by a second AP. The WTRU may perform disassociation from the first AP. The WTRU may activate a WUR and deactivate the PCR. On a condition that the WTRU is disassociated from the first AP, the WTRU may receive, from the second AP, via the WUR, a WUR frame over the at least one channel to enable the WTRU to activate the PCR to initiate association.
