Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for determining whether a user equipment (UE) and a base station of a radio access network (RAN) configured to operate according to compatible variants of a standardized radio access technology (RAT). In some cases, a standard development organization for a geographic territory may modify a standardized RAT in a way that creates a new variant (also referred to as a forked deviation) of the RAT. Depending on what changes are made, the new variant may be compatible or incompatible with the original standardized RAT. This disclosure enables the UE to determine according to which variant of the RAT the RAN is configured to operate and manage connections to the RAN based whether the UE and the RAN are configured to operate according to compatible variants of the RAT.

Abstract: Aspects relate to location services in a wireless communication network. A first wireless communication device may send capability information to the network indicating that the first wireless communication device supports a location services protocol but does not support location services notifications. Upon receiving this capability information, the network may refrain from performing a privacy check procedure directed to the first wireless communication device. As another example, the network may refrain from performing a privacy check procedure directed to the first wireless communication device based on a determination that the first wireless communication device performs a relay function (or otherwise does not support location services notifications or user interaction). As yet another example, the network may determine, based on a privacy profile of the first wireless communication device, that the first wireless communication device is a type of device that is not associated with privacy checks.

Abstract: Methods, systems, and devices for wireless communications are described. An integrated access and backhaul (IAB) node may have a radio resource control (RRC) connection with a first central unit of a first network node. The IAB node may receive an indication that the IAB node is to establish an IAB node-to-central unit connection (e.g., a F1 detour connection) with a second central unit of a second network node via the RRC connection between the IAB node and the first network node. The indication may be associated with a handover between the first network node to the second network node, where the first network node may the source node and the second network node may be the target node, or vice versa. The IAB node may communicate, with the second network node, via the IAB node-to-central unit connection using the RRC connection between the IAB node and the first network node.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a source node may forward a first message between a user equipment (UE) and a core node via a distributed node, wherein the first message is a non-access stratum message. The source node may transmit, to a target node, a second message associated with a migration of the distributed node from the source node to the target node, wherein the second message identifies the forwarding of the first message. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may establish a PC5 unicast link with a second UE. The UE may transmit, to a second UE in a PC5 radio resource control (RRC) message, capability information that includes an indication that the first UE is an unmanned aerial vehicle (UAV). Numerous other aspects are described.

Abstract: Example implementations include a method, apparatus, and computer-readable medium of wireless communication for a network node to transport signaling used to coordinate management of a RAN for local traffic between a first node and a UE across a wireless connection. The network node may establish a first wireless signaling connection between a first node and a second node. The network node may encapsulate or decapsulate traffic associated with a second wireless signaling connection within the first wireless signaling connection. The second wireless signaling connection corresponds to a non-F1 interface of a control plane or user plane network function that terminates at the first node. For instance, the network node may be a consumer premises equipment (CPE) serving a UE, a base station wirelessly serving the CPE, or a core network node providing control for the UE.

Abstract: A method of wireless communication by a user equipment (UE) includes determining whether the UE transitioned between an international area and a national area. The method also includes triggering a public land mobile network (PLMN) selection of a network for receiving service, in response to the UE having transitioned between the international area and the national area. A method of wireless communication by a UE includes performing a PLMN search for a higher priority PLMN. The method also includes determining a list of candidate PLMNs based on the search. The method further includes selecting a PLMN from among the list of candidate PLMNs in response to an identity of a serving PLMN not being a shared mobile country code (MCC). The candidate PLMNs have either an MCC the same as an identity of the serving PLMN or a shared MCC. The selected PLMN has a higher priority than the serving PLMN.

Abstract: Example implementations include a method, apparatus, and computer-readable medium of wireless communication for backhaul transport of non-F1 traffic between an integrated access and backhaul (IAB) node and a. IAB-donor-central unit (CU). The IAB-node may have a connection with the IAB-donor-CU. The IAB-node may provide the IAB-donor-CU with an indication of a non-F1 type of traffic for backhauling between the IAB-node and the IAB-donor-central unit. The IAB-node may receive, from the IAB-donor-CU, a configuration that maps the non-F1 type of traffic to an uplink transport channel at the IAB-node. The IAB-node may transmit uplink non-F1 traffic to the IAB-donor-CU over the uplink transport channel based on the configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may identify a marking of one or more packets, of a quality of service (QoS) flow, with a transport layer identifier associated with a QoS of the QoS flow, wherein the transport layer identifier persists between a user plane function (UPF) and a user equipment (UE). The network node may provide the one or more packets via one or more tunnels with the QoS of the QoS flow. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide techniques that allow the user equipment (UE) that initiated single radio voice call continuity (SRVCC) handover during an active voice session from 5G new radio (NR) to 3G legacy system to effectively transition back from 3G legacy systems to 5G NR systems after conclusion of the active voice session. In one example, the UE may override radio resource control (RRC) connection release with evolved universal terrestrial radio access network (E-UTRAN) frequency information that may direct the UE to camp in E-UTRAN cell (LTE cell). In another example, the UE, as a local policy or configuration, may override the UTRAN cell information when the UE is registered in next generation radio access network (NR) cell as 5G capable UE.

In one embodiment of a method of wireless communication, a mobile device may determine that Radio Access Network (RAN) assistance information is unavailable, the RAN assistance information including a first set of thresholds for switching a Packet Data Network (PDN) connection of the mobile device from a WLAN to a Wireless Wide Area Network (WWAN). The mobile device may further access a second set of thresholds based at least in part on the determining, and the mobile device may determine to switch the PDN connection from the WLAN to the WWAN based at least in part on the second set of thresholds.

Abstract: Systems, methods, and apparatuses for improved traffic management in wireless communications are disclosed. Aspects of the present disclosure provide real-time assessments to a network by leveraging measurement reports from user equipment (UE). In some aspects, the network utilizes channel quality indicator (CQI) information from each of a serving cell and a neighboring cell to identify UE capabilities and expected UE performance prior to either offloading or rerouting traffic to the UE. Accordingly, based on the received CQI information and a greater understanding of the anticipated UE performance, the radio network controller (RNC) may be better equipped to determine whether to offload and/or reroute the traffic scheduled for transmission to the UE via the neighboring cell or the serving cell.

Abstract: Systems and methodologies are described that facilitate communicating PSC split information regarding neighboring cells. The PSC split information can be transmitted in one or more overhead messages selected based on network deployment. Where macro cells and femto cells provide PSC split information, which can be a PSC range for related cells, PSC list, etc., the information can be transmitted in a low priority overhead message since it can be obtained at a source cell. Where only femto cells or closed subscriber group (CSG) cells provide PSC split information, the information can be transmitted in a higher priority more frequently transmitted message. In this regard, the information is available at target cells since not all devices can access CSG cells. Thus, by providing the PSC split information in a more frequently transmitted message, devices can retrieve the PSC split information early on in communications to lower power consumption.
