    Abstract: Methods and apparatus for interference discovery for simultaneous transmission and reception are provided. In an embodiment, a station (STA) receives a STR request message from an access point (AP). The STA transmits a first STR response message to the AP based on the received STR request message. The STA receives a second STR response message transmitted from a second STA to the AP. The STA determines a received power of the received second STR response message. The STA receives a first trigger message from the AP. The first trigger message indicates a STA role field. The STA transmits interference information to the AP. The interference information is based on the determined received power. The STA role field comprises an indication of at least one or more of a primary STA and a secondary STA. The STA aggregates the interference report with a data transmission to the AP in response to the first trigger message.

    Abstract: Methods, apparatus, systems, architectures and interfaces for compressing hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback bits performed by a wireless transmit/receive unit (WTRU) receiving a transmit block (TB) including code block group (CBG) data are provided. The method includes receiving, by the WTRU, information associated with transmitting compressed HARQ-ACK feedback information, receiving, by the WTRU, a TB; determining, by the WTRU, a countdown downlink assignment index (CD_DAI) associated with the received TB; generating, by the WTRU, the compressed HARQ-ACK feedback information by compressing HARQ-ACK feedback bits associated with the received TB; and on condition that: (1) the CD_DAI is equal to zero or (2) the WTRU determines to provide feedback information, transmitting the compressed HARQ-ACK feedback information.

    Abstract: Methods and apparatus for multi-link (ML) steering and control in wireless local area network (WLAN) are disclosed. A station (STA) multi-link device (MLD) may communicate over a plurality of links. The STA MLD may receive, from an access point (AP) MLD, on a first link of the plurality of links, a first frame comprising a ML element, where the ML element includes pausing information indicating a period of time during which the STA MLD will pause transmission and reception on the first link. The STA MLD may send, to the AP MLD, on a second link of the plurality of links and during the indicated period of time, uplink (UL) traffic, wherein the first link and the second link are multi-directional links. The STA MLD may be non-simultaneous transmit and receive (non-STR), and the AP MLD may be capable of STR.

    Abstract: Methods and apparatuses are described herein for multiple access schemes for Wireless Local Area Network (WLAN) with full-duplex radios. For example, an access point (AP), in response to receiving a request to send (RTS) from a first station (STA), may transmit a full-duplex clear to send (FD CTS) to the first STA and a full-duplex request to send (FD RTS) to a second STA. In response to transmitting the FD RTS to the second STA, the AP may receive a clear to send (CTS) from the second STA. The AP may transmit, to both the first STA and the second STA, a FD trigger frame that includes scheduling information to enables FD communication with the first STA for uplink (UL) data and the second STA for downlink (DL) data at a same time. The scheduling information may include timing information and channel information for the FD communication.
