Abstract: Systems, devices and methods for a user equipment (UE) to perform public land mobile network (PLMN) selection with a non-terrestrial network (NTN) dedicated to an international area. The UE receives a downlink message from the NTN, where the downlink message includes a public land mobile network (PLMN) identifier of a first PLMN of the NTN including an information element (IE). The IE indicates that the NTN is dedicated to an international area. Responsive to receiving the downlink message, the UE determines a current location of the UE and determines whether the current location is in the international area. The UE provides an international area notification to an access and mobility management function (AMF) servicing the UE to forward to a home PLMN (HPLMN) of the UE indicating whether the current location is in the international area.

Abstract: Described is a user equipment (UE) that is connected to a network component, the user equipment and the network component configured with a carrier aggregation functionality. The UE performs a method that includes determining a primary component carrier and at least one secondary component carrier associated with the carrier aggregation functionality of the user equipment, determining a component carrier quality measurement (CQM) metric for each of the component carriers, when an uplink data packet is capable of being transmitted over the secondary component carrier, selecting one of the primary component carrier and the at least one secondary component carrier based on the CQM metrics, generating measurement data indicative of the selected component carrier to increase a probability to transmit the uplink data packet over the selected component carrier and transmitting the measurement data to the network component.

Abstract: Described herein are apparatus, systems and methods for adaptive segment size for data transmissions. A method may comprise, at a user equipment (“UE”), identifying a current size setting of a data segment (e.g., a transmission control protocol (“TCP”) maximum segment size (“MSS”)) for communication over a network, receiving current physical layer conditions, receiving historical data, and adjusting the current size setting based on at least one of the current physical layer conditions and the historical data.

Abstract: A device and method performs a handover. The method includes establishing a connection to a cellular network. The method includes determining whether a WiFi network is available for connection. The method includes determining performance data of the WiFi network based upon network metrics. The method includes determining a quality of service (QoS) parameter associated with a currently executed application, the QoS parameter being indicative of whether a handover from the cellular network to the WiFi network is permitted. The method includes performing the handover from the cellular network to the WiFi network when the performance data of the WiFi network satisfies a set of predetermined criteria for the network metrics and the QoS parameter indicates the handover is permitted.
