Methods and system may be used for collision detection for orthogonal frequency division multiple access (OFDMA)-based random access. A wireless transmit/receive unit (WTRU) may receive, from an access point (AP), a first trigger frame triggering random access using OFDMA. The WTRU may transmit, to the AP, in response to the first trigger frame a trigger-based frame including user specific control information in a signal (SIG) field. The WTRU may receive an acknowledgment/negative acknowledgment (ACK/NAK) message indicating that the trigger-based frame was successfully detected at the AP or that the trigger-based frame was not successfully detected at the AP. The WTRU receive, from the AP, a scheduling retransmission frame including rescheduling information for STAs with corrupted UL transmissions. On a condition that the scheduling retransmission frame indicates that a collision of the trigger-based frame was detected, the WTRU may retransmit the trigger-based frame

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.

Methods and an apparatus are disclosed for orthogonal frequency division multiplexing (OFDM) and/or single carrier (SC) based multiple input multiple output (MIMO) hybrid beamforming (HBF) including determining the capabilities of a station (STA) such as the capability for hybrid beamforming, single user MIMO (SU-MIMO), and multi user MIMO (MU-MIMO). An announcement frame with a control trailer may be transmitted to signal a transmission configuration. The announcement frame may be a grant frame or a request to send (RTS) frame if the STA is SU-MIMO capable or a RTS frame or a DMG clear to send (CTS)-self frame if the STA is MU-MIMO capable. One or more directional multi-gigabit (DMG) antennas may be configured based on the announcement frame. One or more sounding symbols may be transmitted and feedback may be provided based on the sounding symbols. An HBF signal may be transmitted based on the sounding symbol(s) and/or feedback.

Methods, systems, and apparatuses are disclosed for operating a wireless transmit/receive unit (WTRU) in a wake-up radio (WUR) state and receiving a (WUR) frame from an access point (AP). A WUR frame may include a multicast counter (MC) field. A determination may be made whether a received MC value in a received MC field is a same value as a stored MC value. Where a received MC value is the same value as a stored MC value, the WTRU may operate in the WUR state. Where a received MC value is not the same value as a stored MC value, the WTRU may operate in a primary connectivity radio (PCR) state.
