Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques at a network provide for efficiently considering parameters of a network slice when determining whether to provide access to the network slice, allow the establishment of a session via the network slice, or grant access to resources for communications via the network slice. Further, the described techniques at a user equipment (UE) provide for efficiently determining when or whether to retry to access a network slice, retry to establish a session via the network slice, or retry to access resources for communicating via the network slice.

Abstract: One aspect relates to initiating, by a device, a connection with an application server associated with one or more application services. A gateway derives an uplink network token and/or a downlink network token. The tokens are provisioned to the device and/or an application server over the user-plane. The tokens are included with uplink and/or downlink packets, respectively. Another aspect relates to receiving a data packet at a gateway. The gateway determines a requirement for a network token from the packet. The gateway derives the network token based on a device subscription profile maintained by a network. The network token may be sent with the packet to a destination address associated with the packet. A packet including a network token may be received at a gateway. The gateway may verify the network token and send the data packet to an application server or a device if the verifying is successful.

Abstract: Methods, systems, and devices for wireless communications are described. A public land mobile network (PLMN) may indicate to a user equipment (UE) which network slices are supported by available non-Third Generation Partnership Program (3GPP) interworking functions (N3IWF). The PLMN may provide, to the UE, non-3GPP access node (N3AN) selection information that indicates a set of N3IWFs and a set of supported network slices. The network slices may be indicated via Network Slice Simultaneous Registration Group (NSSRGs) associated with each N3IWF. If a UE is not configured to support NSSRGs, the PLMN may indicate network slices that may be used concurrently and may indicate one or more N3IWFs that support the indicated network slices. The UE may select an N3IWF based on one or more selected network slices. The UE may register with the N3IWF and connect to the N3AN based on an internet protocol address associated with the N3IWF.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive a broadcast remote identification (BRID) message from a unmanned aerial vehicle (UAV), where the BRID message may include an identity of the UAV. The wireless device may identify UAV information associated with the UAV based on the UAV ID. In some cases, the wireless device may be configured with information that enables the identification of the UAV information. In other cases, the wireless device may request the UAV information from a network entity, such as a UAV flight management system (UFMS), which provides the requested UAV information. In some examples, the UFMS may request the UAV information from an unmanned aerial system (UAS) service supplier (USS) based on the BRID information. Upon identifying the UAV information, the wireless device may broadcast the UAV information to manned aerial vehicles, thereby indicating a presence of the UAV.
