Methods, devices and systems are provided for performing for multi-user (MU) transmission. A wireless transmit/receive unit (WTRU) may be configured to receive a frame, decode the received frame and determine whether the received frame is a null data packet (NDP) multi-user (MU) media access control (MAC) physical layer convergence protocol (PLCP) protocol data unit (PPDU) (NDP MU MAC PPDU) based on meeting an NDP condition. The NDP MU MAC PPDU may correspond to an MU transmission and may include a PLCP header which includes an NDP signal (SIG) field having MU control information. Based on the received frame meeting the NDP condition, the WTRU may be further configured to process the NDP SIG field, generate a response based on the NDP SIG field and the MU control information, and transmit the response.

A method for concurrent execution of multiple protocols using a single radio of a wireless communication device is provided that includes receiving, in a radio command scheduler, a first radio command from a first protocol stack of a plurality of protocol states executing on the wireless communication device, determining a scheduling policy for the first radio command based on a current state of each protocol stack of the plurality of protocol stacks, and scheduling the first radio command in a radio command queue for the radio based on the scheduling policy, wherein the radio command scheduler uses the radio command queue to schedule radio commands received from the plurality of protocol stacks.

In one embodiment, a method is provided for customization of a mobile communications device's data session retry mechanism in a wireless packet data service network. The mobile communication device requests activation of a data session with a node via the wireless network and receives a reject message via the wireless network in response to the request for activation of the data session, the reject message including a cause code. If the cause code corresponds to a no-retry behavior of the data session retry mechanism of the mobile communication device, the mobile communications device no longer requesting activation of a data session with the node.

Adaptive scanning is described. The adaptive scanning may include performing a passive scan of communications associated with a device, where the passive scan comprises observing one or more communications of the device over a network. One or more attributes associated with the device based on the passive scan are determined and an active scan of the device is performed based on the one or more attributes based on the passive scan. The active scan is customized for the device based on the one or more attributes determined based on the passive scan and the active scan comprises sending one or more requests to the device. One or more attributes associated with the device may be determined based on the active scan. The one or more attributes based on the passive scan and the one or more results based on the active scan associated with the device are stored.

Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive signaling indicating a set of multicast configurations for a set of multicast modes supported by the UE. Each multicast mode of the set of multicast modes may be associated with one or more radio resource control (RRC) states. The UE may determine a multicast configuration of the set of multicast configurations based on an RRC state according to which the UE is operating. The UE may receive, while operating according to the RRC state, multicast data according to the determined multicast configuration.

A method including entering, by machine, a first field defined by first field boundaries; and automatically associating the machine with a first wireless network defined by the first field boundaries, the first wireless network comprising a secured data communications network.

The present disclosure describes methods and apparatus for supporting QoS and media flow mapping over simultaneous connection for a user equipment (UE), when the simultaneous connections are established over heterogeneous systems having different QoS models, such as 3GPP LTE (4G) QoS model and 3GPP 5G QoS model. The 4G and 5G networks may share the user plane and/or share a policy server. In one aspect, methods for consolidating and distributing the QoS for the NGBR flow and bearer across simultaneous PDN connection over 4G and PDU session over 5G to the same data network (DN) or different DNs are provided. In another aspect, methods are provided for mapping one or more media flows of a multimedia session, such as an IMS session, over simultaneous 4G and 5G connections for a UE are provided, where the 4G connection and the 5G connection for the UE may or may not share the assigned IP address for the UE.

According to various embodiments, a receiving station (STA) may receive a physical layer protocol data unit (PPDU). The PPDU may include a first signal field and a second signal field. The first signal field may include 3-bit information. The receiving STA may determine whether the PPDU is related to single user (SU) transmission or multiple user (MU) transmission, whether the PPDU is related to orthogonal frequency division multiple access (OFDMA), whether the PPDU is related to multi-user multiple input multiple output (MU-MIMO), and whether the PPDU is related to a trigger-based (TB) PPDU, based on the 3-bit information.
