Abstract: Systems and methods of protecting an initial NAS message are described. The NAS message is encrypted using the home PLMN public key during initial registration with the network using a registration request message. An AMF of the serving PLMN sends a serving PLMN public key which is then used to encrypt information including an S-NSSAI of later initial NAS messages after initial registration is completed. The S-NSSAI may not be sent in the later initial NAS message if the S-NSSAI is provided at an access stratum level. The RRC message may contain an indication that the S-NSSAI is encrypted using the serving PLMN public key.

Abstract: Systems and methods of providing UE capability are described. A capability ID is associated with the same Radio Capability information for multiple UEs. If the capability ID is validated at a network node, the UE provides the capability ID to a RAN node, which obtains the capability information from the network node after providing the received capability ID to the RAN node. The capability ID is received in an RRC Setup Complete. Security Mode Complete or Reconfiguration Complete message. The network node, if the Radio Capability information is not available, requests and receives the Radio Capability information and associates it with the capability ID, and marks that the capability ID as not validated until a threshold number of the UEs have provided the same Radio Capability information. The capability ID is based on a UE device type, manufacturer and software version.

Abstract: Embodiments of an integrated access and backhaul (IAB) donor, IAB node, and methods of communication are generally described herein. An IAB network may comprise a plurality of IAB nodes to operate as relays between the IAB donor and one or more User Equipment (UE). The IAB donor may, for each of the IAB nodes, allocate a plurality of subframes to the IAB node. Each allocated subframe may have a subframe type that is one of: a downlink subframe, an uplink subframe, a flexible subframe or a not available subframe. The IAB donor may transmit, from a central unit (CU) of the IAB donor to a distributed unit (DU) an IAB node over an F1 interface, a resource coordination request message that indicates the subframe types of the plurality of subframes.

Abstract: Systems and methods of reducing control plane latency in a 5G IAB network are described. SRs transmitted between nodes indicate that a control plane PDU is to be transmitted. The SRs use periodic resources or OCCs reserved for control plane signaling and are initiated by an RRC message or RACH from the UE. The SRs are initiated if the LCD field in the MAC sub header of the RRC message indicates the CCCH or the DCCH logical channel. If the PDU is available after the original resource, a resource is used that is provided via another grant, which is periodically provided or automatically initiated due to failure to transmit on the original grant. The SR or RRC message can also specify a delayed timeslot for the grant. For contention-based procedures the RACH preamble is randomly selected or selected from among a set of RACH preambles assigned for RRC procedures.

Abstract: Systems and methods of providing uplink in-order packet delivery of a QoS flow offloaded in a 5G network are described. An uplink forwarding tunnel is established between a source and target node after a determination is made to offload a QoS flow of a UE to the target node. The source node receives a SDAP PDU from the UE that contains an end marker and, in response, sends a GTP-U end marker packet to the target node via the uplink forwarding tunnel. The target node buffer packets associated with the QoS flow received from the UE after establishment of the uplink forwarding tunnel until the GTP-U end marker packet is received from the target node via the uplink forwarding tunnel and, in response, sends the buffered packets to the 5GC.
