    Publication number: 20240413959
    Abstract: A base station, a wireless device and methods therein for supporting radio communication, wherein the base station employs carrier aggregation with multiple carriers serving a primary cell, PCell, and at least one secondary cell, SCell. The base station signals (3:3) an SCell status to the wireless device, the SCell status indicating whether the at least one SCell will be in active state where the base station transmits downlink signals on a carrier serving the at least one SCell, or in inactive state where the base station does not transmit downlink signals on the carrier serving the at least one SCell. Thereby, the wireless device can adapt its behaviour depending on the signalled SCell status, e.g. by turning off its receiver and not perform any signal measurements when the SCell is in inactive state.

  • RLM and beam failure detection based on a mix of different reference signals
    Patent number: 12156243
    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.
