  • Publication number: 20250330373
    Abstract: Methods and systems are described for indicating and configuring machine learning (ML) model support in a user equipment (UE) in a network. A UE can provide model support information to a node, including a ML type and/or version information of at least one model associated with a certain functionality. A network node uses the support information, and optionally previous model ID allocation information in current or other nodes, to determine at least one model ID, and signals it to the UE. The model ID refers to the model in subsequent model handling-related signaling between the UE and the node. The node assigns the model ID such that the UE and the node are aware that a given model ID refers to a given model or model version (e.g., the mapping is unique for the UE). The model ID can also be unique within a functional area, for example CSI reporting.

  • Patent number: 12452870
    Abstract: Radio communication systems, devices and methods for enabling variable subband configuration of one or more search spaces. In a first time interval, a UE attempts to decode one or more control channels on downlink or sidelink resources of a first sub band configuration. In a second time interval, the UE attempts to decode one or more control channels on downlink or sidelink resources of a second sub band configuration. The first subband configuration spans a first frequency range and the second subband configuration spans a second frequency range different from the first frequency range.

  • Patent number: 12381671
    Abstract: Limited uplink bandwidth radio network devices are supported on wide bandwidth uplink carriers by configuring and controlling the use of multiple control regions within the uplink carrier bandwidth. In some embodiments, the total bandwidth of the uplink carrier is divided into a plurality of sub-band portions, wherein each sub-band portion includes at least one control region nominally dedicated to the transmission of uplink control signaling. Radio network devices are configured with a specified portion of the uplink carrier bandwidth for use for uplink transmission, which includes at least one control region. Radio network devices may be provisioned or provided with information regarding control regions reserved for control signaling by other radio network devices. The radio network devices may be dynamically configured to allow or suppress uplink data signaling in specified control regions, or portions thereof.
