Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for wireless communication by a user equipment (UE). In one aspect, the UE is configured to generate a handover request related to a wireless communication session between the UE and a wireless local area network (WLAN) device, and establish, independent of an access check, a radio resource control (RRC) connection with a base station. In another aspect, the UE is configured to perform an access check based on a bias value, and establish an RRC connection with a base station based on a result of the access check. The access check performed based on a communication indicator related to a wireless communication session between the UE and a WLAN device.

Abstract: Methods, systems, and devices for wireless communication are described. In one example, an aerial user equipment (UE) may receive an indication of a priority for cell selection for aerial UEs from each cell in a set of cells and may select a cell from the set of cells based on the priority of each cell in the set of cells. In another example, an aerial UE may connect to a network available to aerial UEs and non-aerial UEs for auxiliary communications, when appropriate. In yet another example, when an aerial UE transitions to a new mission status, the aerial UE may transmit a tracking area update (TAU) if the aerial UE is connected to a cell in a tracking area that does not support the new mission status. In yet another example, a base station may page an aerial UE based on a mission status of the aerial UE.

Abstract: Aspects described herein relate to enabling data network devices to communicate using wireless network nodes, including user equipment (UE) and/or core network nodes, in a wireless network. The data network devices can have associated mechanisms for interfacing with the wireless network nodes, and the wireless network functions can facilitate transparent transfer of control information for the associated mechanisms.

Abstract: Methods, systems, and devices for wireless communications are described that provide for truncated identification indicators. A user equipment (UE) may receive control signaling indicating a truncating configuration for an identification indicator. The truncating configuration may indicate a set of bits within an initial identification indicator to remove to generate a truncated identification indicator. The UE may remove the indicated set of bits and transmit the truncated identification indicator to a base station. The base station may receive the truncated identification indicator and reconstruct the initial identification indicator according to the truncating configuration. The base station may reconstruct the initial identification indicator by adding the set of bits (e.g., removed by the UE to generate the truncated identification indicator) to the truncated identification indicator.

Abstract: Certain aspects of the present disclosure provide techniques for selecting policies for routing of data traffic. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes selecting at least one policy for routing of data traffic to a network, wherein the policy comprise an access network discovery and selection policy (ANDSP) if the UE has the ANDSP provisioned regardless of whether the UE is registered to evolved packet core (EPC) or fifth-generation core network (5GCN), and communicating the data traffic to the network based on the selection.

Abstract: Aspects directed towards steering of roaming (SoR) are disclosed. In one example, a communication from a public land mobile network (PLMN) is received by a user equipment (UE) in which the communication indicates an acceptance of a UE registration with the PLMN. This example further includes performing a determination of whether an SoR indicator associated with a home PLMN (HPLMN) is embedded within the communication. The UE then manages PLMN selection according to the determination. In another example, a UE is configured to operate according to an SoR configuration in which the UE is configured to ascertain whether an SoR indicator is embedded within a communication from a PLMN. An SoR indicator associated with an HPLMN is then generated and subsequently transmitted from the HPLMN to the UE via the PLMN.

The apparatus receives a network slice-specific authentication command for a network slice that is currently allowed. The apparatus determines that the network slice is being authenticated based on the received network slice-specific authentication command. The apparatus blocks session management procedures associated with the network slice based on the determination that the network slice is being authenticated.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may determine whether the UE is inside or outside of a vehicle with a relay device. Techniques for determining whether the UE is inside or outside of the vehicle are described herein. The UE may determine whether to camp on a cell of the relay device based on whether the UE is inside or outside the vehicle. The base station may perform connected mode mobility for the UE based on whether the UE is inside or outside the vehicle.

Abstract: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by a user equipment (UE). The method generally includes registering with a first public land mobile network (PLMN) of a first network operator in response to detection of an interruption event associated with a second PLMN of a second network operator; determining that the interruption event has ended; and taking one or more actions to communicate with the second PLMN in response to the ending of the interruption event, wherein taking the one or more actions to communicate with the second PLMN is based on a constraint associated with access attempts to the second PLMN.

Abstract: A method of wireless communication performs a public land mobile network (PLMN) search for a higher priority PLMN. The PLMN search includes a candidate PLMN having a different mobile country code (MCC) than a serving PLMN. The method switches to the higher priority PLMN when the PLMN search locates the higher priority PLMN. A method determines whether a user equipment (UE) has transitioned between an international area and a national area. The method triggers PLMN selection in response to the UE having transitioned between the international area and the national area.

Abstract: Aspects of the present disclosure provide for a security model for enabling multiple connectivity and service contexts while sharing a single connectivity context to establish a network connection. A context (e.g., connectivity context, service context, security context) is a set of information describing the connectivity, service, or security established between two or more entities. The connectivity context and service context may be established at different network nodes or entities. In one aspect of the disclosure, a connectivity context includes an Evolved Packet System (EPS) Mobility Management (EMM) context or both an EMM context and an EPS Session Management (ESM) context.

Abstract: Certain aspects of the present disclosure provide techniques for performing a public land mobile network (PLMN) selection procedure based on allowed PLMN(s) in a particular country of a user equipment (UE). An example method generally includes determining a country in which the UE is located, creating a list of available PLMNs, that are allowed to be selected in the country in which the UE is located, for access to a non-terrestrial network (NTN), and performing a PLMN selection procedure for access to the NTN based on the list of available PLMNs and the country in which the UE is located.

In some aspects, a network node may determine at least one parameter associated with use of a relay device to forward data between the network node and one or more wireless devices, the at least one parameter including a use time associated with the relay device, an amount of data associated with the relay device, or a combination thereof. The network node may transmit, to a central network node, the at least one parameter. Accordingly, the network node and/or the central network node may determine a payment amount associated with the relay device based at least in part on the at least one parameter. Numerous other aspects are provided.
