    Abstract: Techniques, devices and systems are disclosed for generating a resource request poll comprising at least one response criteria, transmitting the resource request poll, receiving a resource request report from STAs that meet at least one response criteria. A trigger frame may be transmitted to the at least one STA based on the resource request report from the at least one STA. The response criteria may include at least one of a NFRP, a UL access type, a delay bound, an NDP feedback report AC, a number of indicated AID bits, an AID range, an information requested, a number of bits to be included in NDP feedback report or preamble, number of LTFs to be included in the NDP feedback report or preamble, and a number of bits to be included in NDP feedback report or preamble per LTF or per N LTF symbol.

    Abstract: Methods for transmitting and receiving enhanced broadcast transmissions are provided herein. A method performed by a receiving station (STA) may include receiving, from a transmitting STA, a frame including a broadcast service element The broadcast service element includes one or more fields associated with enhanced broadcast service (eBCS) traffic streams that may be provided by the STA. At least one of the fields comprises an identifier associated with eBCS traffic streams, a field indicating whether negotiation with the transmitting STA is required to receive data of the eBCS traffic streams, and scheduling information for receiving a broadcast transmission including the data of the eBCS traffic streams. The method includes receiving, based on the scheduling information, the broadcast transmission including the identifier associated with the eBCS traffic streams and data of the eBCS traffic streams.

    Abstract: Methods and apparatuses are described herein for rediscovery and medium access for wake-up radios. For example, a wireless transmit receive unit (WTRU) may receive, via a first transceiver, a frame that includes a wake-up radio (WUR) operation element having a first counter value. The WTRU may deactivate the first transceiver and activate a second transceiver, wherein the first transceiver enters into a doze state and the second transceiver is in an awake state. The WTRU may then receive, via the second transceiver in the awake state, a WUR frame that includes a second counter value indicating an update of a plurality of basic sewer set (BSS) parameters associated with the first transceiver. On a condition that the second counter value is different than the first counter value, the WTRU may activate the first transceiver to update the plurality of BSS parameters, wherein the first transceiver enters into an awake state.
