  • Publication number: 20220070749
    Abstract: Methods, systems, and devices for wireless communications are described that support techniques for handover in non-terrestrial networks. The described techniques provide for handovers such that a user equipment (UE) may be provided information prior to handover to facilitate rapid handover and rapid recover if handover fails. The information is based on predicted handovers due to motion of non-terestrial network devices (e.g, satellites).

  • Publication number: 20220058494
    Abstract: In an approach for a hybrid ensemble model leveraging edge and server side inference, a processor receives data on an edge device. A processor sends the data to a server. A processor performs, in parallel, inference on the data using a first model on the edge device and a second model on the server. A processor returns a result of the second model to the edge device. A processor ensembles, on the edge device, a result of the first model and the result of the second model based on a set of weights to produce an ensembled result. A processor outputs the ensemble result for a user to view through a user interface of the edge device.

  • Publication number: 20220038168
    Abstract: Methods, systems, and devices for wireless communications are described. In some networks, a user equipment (UE) may switch between serving beams of a transmitting device that are associated with different bandwidth parts of a radio frequency spectrum. To improve aspects of beam measurement and selection, a UE may be configured to support various techniques for beam measurement according to the different bandwidth parts. For example, a UE may receive a beam measurement configuration associated with one or more beams, and may monitor for reference signals associated with the beams using the different bandwidth parts. The UE may determine a channel quality of one or more of the beams based on the monitoring, and transmit a beam measurement report to the network in accordance with the beam measurement configuration. In some examples, such a report may be transmitted based on the UE determining that an event condition is satisfied.
