Abstract: 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.

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: A wireless transmit/receive unit (WTRU) or access point (AP) may generate a protocol data unit (PDU) of a first 802.11 protocol and a preamble and data of a second 802.11 protocol. The preamble and data of the second 802.11 protocol may be arranged on resources of the PDU of the first 802.11 protocol with shaping sequences for concurrent transmission.

Abstract: An access point (AP) that supports the IEEE 802.11ba protocol may transmit a frame including a physical layer (PHY) preamble to one or more stations (STAs) over a channel. The PHY preamble may include a plurality of repeated modulated legacy signal (L-SIG) fields to spoof a recipient of the frame and protect a wake up signal (WUS) to be subsequently transmitted by the AP. The AP may transmit the WUS to at least a first STA of the one or more STAs, wherein the at least the first STA is a IEEE 802.11ba compliant STA.
