Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications system may utilize an inter-system information report message (e.g., a self-organizing network (SON) information report message) to support inter-system mobility load balancing (MLB). For example, a first node, operating in accordance with a first radio access technology (RAT), may receive an information report message from a second node operating in accordance with a second RAT. The information report message may include a periodic load reporting request information element (IE) or an event-triggered load reporting request IE. In response, the first node may determine a traffic load based on the load reporting request and transmit, to the second node, an information report message which includes one or more IEs for reporting the determined traffic load. The exchange of the load information via the IEs may enable for MLB between nodes of different RAT.

Abstract: Wireless communication systems and methods related to enhancing initial access for multi-beam operations. A user equipment (UE) selects a synchronization signal block (SSB) that corresponds to a beam and has a reference signal received power (RSRP) above a threshold. The UE receives a system information block (SIB) that includes a plurality of SSB and beam-specific system information pairs. The UE selects beam-specific system information by matching the selected SSB to one of SSBs in the multiple SSB and beam-specific system information pairs. The UE establishes a connection with a base station (BS) using the beam-specific system information.

A user equipment (UE) may measure quality of experience (QoE) metrics and transmit a QoE report that is formatted to be readable by a base station, such that a base station may receive the QoE report and independently perform adjustments associated with the service being utilized by the UE. A UE may receive a configuration message that includes a first configuration for reporting QoE measurements to a base station and a second configuration for reporting QoE measurements to a QoE server.

Abstract: Inform a master node about the feasible of secondary node cells during resumption of dual connectivity may require a large message. Additionally, the message may need to be encrypted. A solution to overcome the size and security limitation is to report a short identifier (or index) which is only shared between the UE and the MN. Accordingly, an apparatus, e.g., a UE, may be configured to receive, from a master node, a configuration comprising a mapping of cell identities for a plurality of secondary cells for reporting SN measurements and transmitting an SN report comprising measurements for at least a subset of the plurality of secondary cells using the mapping of cell identities. The apparatus may be configured to receive, from a first master node, a configuration for MN-DC, enter an inactive state or an idle state, and resume a connected state with a second master node.

Abstract: Man-in-the-middle attacks on reference signals used for positioning a mobile device in a wireless network can be detected through time and/or angle consistency checks. Time consistency checks may be based on a consistency of peak location and/or power delay profile across multiple reference signals and/or across different signal types, for example. Angle consistency checks may be based on a consistency of an angle at which a reference signal is received across multiple reference signals and/or in comparison with an expected angle, for example. Embodiments may further include reporting detected attacks.

Abstract: Methods, systems, and devices for wireless communications are described. A server (e.g., a network entity, a model repository) may select user equipment (UEs) to participate in a federated learning procedure for training a predictive model. Based on selecting the UEs, the server may determine a set of training parameters for a training configuration for the federated learning procedure. The server may transmit an indication of the training configuration to the UEs. The server may activate the federated learning procedure by transmitting an activation indication to the UEs. Each UE may locally train the predictive model according to the training configuration, and may report the model parameters to the server. The server may aggregate the reported model parameters into an updated model parameter set. The server may assign an updated parameter set identifier (PS ID) to the updated model parameter set and may inform the UEs of the updated PS ID.

Abstract: Methods, systems, and devices for wireless communications are described. In the context of a service-based wireless system, a user equipment (UE) may communicate with one or more core network services offered by a service-based network, where respective core network services are in one of an active, inactive, or unconnected state at the UE. The UE may be configured to maintain service contexts for communicating with core network services that are in an active or an inactive state at the UE, where signaling between the UE and each respective core network service may be used to activate or deactivate the respective core network services at the UE between the active and inactive states. By maintaining service contexts for inactive core network services, the UE may be able to quickly and efficiently resume communications with a core network service in accordance with the stored service context upon activating the core network service.

Abstract: In a wireless access network, a false base station (FBS) may imitate a legitimate base station by repeating the transmissions of the legitimate base station at a higher power level such that one or more user equipment (UEs) synchronize with the FBS instead of the legitimate base station. The present disclosure provides a UE that detects an FBS. The UE may estimate a time of arrival of different multipath components of a downlink signal corresponding to a physical cell identity. The UE may determine an existence of FBS based on a difference between the times of arrival of two of the different multipath components exceeding a threshold amount of time. The UE may perform a mitigation operation in response to determining the existence of the FBS.

Abstract: Methods, systems, and devices for wireless communications are described. An end-to-end routing layer may address packets between a user equipment (UE) and core network services offered by a service-based network on a per-core network service basis. A UE may communicate directly with a core network service (e.g., based on a network address associated with the core network service) or indirectly (e.g., through a proxy service). The UE may select access stratum (AS) resources over which to transmit an uplink packet data unit based on the target core network service. The UE may receive control signaling from a distributed unit, a system information block (SIB), or point-to-point signaling from the core network services indicating specific AS resources for each core network service. The UE may select logical channels for transmitting the uplink packet data units to specific core network services based on the AS resources associated with each service.

Abstract: Methods, systems, and devices for wireless communications are described. In a service-based network, groups of core network services may share a user equipment (UE) credential or network subscription. Signaling between a UE and a service-based network (e.g., via a distributed unit) enables the UE to establish a service context for communications with multiple core network services in a same service group. A UE may receive control signaling from the network indicating service groups offered by the service-based network. The control signaling may indicate the services included in each service group and how to access the service group. The UE may transmit an access request indicating a selected service group to the network, and in response, the network may indicate a service context for communicating with the services included in the service group. The UE may use the same service context to access the different services in the service group.

Abstract: Methods, systems, and devices for wireless communications are described. A communication link between the UE and a serving base station may be established. The UE may measure, at an application layer of the UE, a set of quality of experience variables associated with different service types. The UE may measure, at an access stratum of the UE, a set of radio resource management variables associated with the communication link between the UE and the serving base station and a communication link between the UE and a corresponding set of one or more neighboring base stations associated with the communication links. The UE may transmit a measurement report to the serving base station indicating information associated with the quality of experience variables and the radio resource management variables in a multi-layer readable format.

Abstract: Methods, systems, and devices for wireless communications are described. In the context of a service-based wireless system, a user equipment (UE) may identify (e.g., via signaling from the network or based on a subscriber identity module (SIM)) a set of core network services offered by a service-based network that interfaces with a radio access network (RAN) associated with the network entity. Each of the respective core network services may be associated with a corresponding network address. The UE may transmit a service request to a network address associated with a core network service included within the set of offered core network services, and may receive a service context for communicating with the core network service in response to the service request. The UE may then communicate service messages with the core network service (via the network entity) in accordance with the received service context.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a measurement configuration including trigger conditions for performance of handover procedures within a service-based wireless system. The UE may transmit a message indicating a satisfaction of a trigger condition to a source network entity, a mobility service offered by a service-based network, or both. After performance of a handover decision by the source network entity, the mobility service, or both, the mobility service may select a target network entity for the handover procedure. The mobility service may select a target network entity that supports at least one active core network service at the UE. The UE may then receive a handover command from the mobility service, and may perform a handover procedure to the target network entity.
