  • Method and radio node for handling CSI reporting
    Patent number: 11659428
    Abstract: A radio node and a UE are described, and methods and computer programs therein to handle separate aperiodic CSI reports for one or more static subframes, in which the direction of signal transmission is fixed, and one or more flexible subframes, in which the direction of signal transmission is variable. The method performed by a UE comprises receiving a trigger for an aperiodic CSI report as part of an uplink grant from a radio node in a static downlink subframe, said trigger indicating a CSI subframe set related to the one or more static subframes. The method further comprises reporting to the radio node, in a CSI reporting subframe, a result of an aperiodic CSI measurement for a CSI reference in the CSI subframe set. The method further comprises receiving a second trigger that relates to the one or more flexible subframes and reporting the results to the radio node.

  • RLM and Beam Failure Detection based on a Mix of Different Reference Signals
    Publication number: 20230105488
    Abstract: A user equipment, UE, performs measurements based on a plurality of RLM sources received in beam-formed downlink signals, where the measurements indicate a quality of a given cell or beam. The plurality of sources comprises two or more of: first reference signals (RSs), second RSs of a different type than the first RSs, and one or more physical channel quality indicators obtained from non-reference-signal data in the beam-formed downlink signals. For each of the plurality of sources used to perform measurements, the UE determines whether a measurement for the respective source indicates an out-of-sync event in response to the measurement being below a first threshold. The UE then performs an RLM action based on determined occurrences of out-of-sync events.
