Abstract

The present application relates to coordination between a UE and a network for collection of data by the UE and use of the data by a model hosted by the network. In an example, the network configures the UE to perform and log MDT measurements for the model. The UE can be configured to do so across all RRC states, including an RRC_CONNECTED state. The UE can also be configured to report such logged MDT measurements in more than one state, such as in an RRC_INACTIVE state in addition to the RRC_CONNECTED state.

The same reference numbers may be used in different drawings to identify the same or similar elements. In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular structures, architectures, interfaces, and techniques in order to provide a thorough understanding of the various aspects of various embodiments. However, it will be apparent to those skilled in the art having the benefit of the present disclosure that the various aspects of the various embodiments may be practiced in other examples that depart from these specific details. In certain instances, descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the various embodiments with unnecessary detail. For the purposes of the present document, the phrases “A/B” and “A or B” mean (A) , (B) , or (A and B) ; and the phrase “based on A” means “based at least in part on A, ” for example, it could be “based solely on A” or it could be “based in part on A. ” Embodiments of the present disclosure relate to coordination between a user equipment (UE) and a network for collection of data by the UE and use of the data by a model hosted by the network. The model can be an artificial intelligence (AI) model (in one example, the AI model can be a machine learning (ML) model) that provides a network function (e.g., channel state information (CSI) feedback, beam management, positioning, etc. ) . In an example, the data includes minimization of drive test (MDT) data. The coordination can include the network configuring the UE to perform measurements and log the related measurements data across different radio resource control (RRC) states, including an RRC_CONNECTED state. The configuration can indicate a timing to start measurement for logging and/or a measurement event for doing so. The configuration can also indicate particular measurement quantities to perform (e.g., a per beam measurement) and/or can enable the UE to report unspecified measurements or data in a transparent container. Further, the UE can log the measurements in a memory buffer (e.g., an access stratum (AS) buffer and/or an application buffer) . If the size of the memory buffer exceeds a threshold, the UE can be enabled to send the logged measurements even when the UE is in an RRC_INACTIVE state (e.g., by using a measurement object short data transmission (MO-SDT) ) . These and other features are further described herein below. Embodiments of the present disclosure provide various technical advantages. Fo
