    Abstract: There is provided a method performed by a user equipment (UE). The method comprises: receiving one or more inter-cell multiple Transmission Reception Point (mTRP) configurations; initiating a re-establishment procedure with a network node; and in response to initiating the re-establishment procedure, releasing at least one of the one or more inter-cell mTRP configurations. There is another method performed by a UE. The method comprises: receiving one or more inter-cell mTRP configurations; obtaining an indication for performing at least one of: releasing at least one of the one or more inter-cell mTRP configurations and storing at least one of the one or more inter-cell mTRP configurations, for a re-establishment procedure; initiating a re-establishment procedure with a network node; and performing one of: releasing at least one of the one or more inter-cell mTRP configurations and storing at least one of the one or more inter-cell mTRP configurations, according to the obtained indication.

    Abstract: A method performed by a first network node operating as a Master Node (MN) for a user equipment (UE) configured with Multi-Radio Dual Connectivity, includes receiving a first request for conditional PSCell change (CPC) for the UE from a source secondary node (S-SN), the first request indicating a plurality of candidate cells for PSCell configuration, and transmitting a second request for CPC to a candidate target secondary node (T-SN), the second request indicating one or more candidate cells of the plurality of candidate cells for PSCell configuration that are served by the T-SN. The method further includes receiving a response from the T-SN indicating that a subset of the identified candidate cells were accepted by the T-SN and/or identifying a new candidate cell for CPC for the UE, and determining whether or not to configure the UE with CPC based on the response from the T-SN.

    Abstract: A method performed by a source Master Node, MN, includes transmitting a request for handover for a user equipment, UE, with deactivated secondary cell group, SCG, to a target MN, wherein the request is transmitted with user plane traffic load information. The method includes receiving, from the target MN, a response including a Handover Command including a reconfiguration message containing reconfigurationWithSync with the UE target configuration and an indication of activated or deactivated SCG. The method includes transmitting the reconfiguration message containing the reconfigurationWithSync to the UE with the UE target configuration.

    Abstract: A method (200) performed by a UE (102). The method includes receiving (s202) one or more messages for activating at least i) a first set of configured TCI states and ii) a second set of configured TCI states, wherein the first set of activated TCI states is associated with a first PCI and indicates a first set of reference signals, and the second set of activated TCI states is associated with a second PCI and indicates a second set of reference signals. The method also includes performing (s204) beam failure detection, BFD, monitoring. Performing the BFD monitoring comprises: determining (s206) whether a beam failure with respect to the first PCI has occurred based on the first set of reference signals; and determining (s208) whether a beam failure with respect to the second PCI has occurred based on the second set of reference signals.

    Abstract: A method of operating a master node includes determining to configure conditional PSCell addition or change (CPAC). A request is transmitted to a SN to prepare a conditional SN addition, a response therefrom confirms that a UE may be accepted unless a canceling message is later received. A RRC message is transmitted to the UE containing CPAC configurations for candidate target cell(s), where the RRC message contains condition(s) which the UE should monitor and message to be applied when condition fulfilled. Multiple MN or MCG related configurations are monitored for reception of messages from the UE. A message is received from the UE on one of the multiple MN or MCG related configurations monitored. The method detects which one of the multiple MN or MCG related configurations the UE has applied and responsively reconfigures the MN based on the detected one of the multiple MN or MCG related configurations.

    Abstract: There is provided a method in a wireless device configured with multiple Physical Cell Identities (PCIs) for a mobility procedure, wherein the wireless device is configured with one or more cells operating in a same serving frequency, each cell associated with one or more PCIs. The method comprises: selecting a PCI among the multiple PCIs; determining cell measurement results based on cell measurements performed on the selected PCI, wherein the cell measurements represent measurements of a serving cell; and determining whether or not to trigger an event for measurement reporting, based on the cell measurement results. The wireless device may also select a subset of PCIs among the multiples PCIs and determine cell measurement results based on cell measurements performed based on the selected subset of PCIs.
