  • Publication number: 20240129983
    Abstract: Systems, methods and apparatus are disclosed for user equipment and network nodes. An example method performed by a user equipment (UE) includes the UE detecting a failure relating to a connection between the UE and a Master Cell Group (MCG). The UE provides, to a master node via a Secondary Cell Group, SCG, a first message relating to the detected failure. The UE receives, from the master node via the SCG, a second message indicating to the UE to perform a connection reconfiguration. An example method performed by the master node includes the master node receiving, from the UE via the SCG, the first message including information relating to the detected failure of the connection between the UE and the MCG. The master node determines, based on the first message and a user equipment context, to perform a connection reconfiguration. The master node provides, to the UE via the SCG, the second message indicating to perform the connection reconfiguration.

  • Patent number: 11743908
    Abstract: A communication device receives an uplink grant from a node of a cellular network. The uplink grant indicates uplink radio resources allocated to the communication device in reoccurring time intervals. For each of these time intervals, the communication device selects between an active mode and an inactive mode. In the active mode the communication device performs an uplink transmission in the allocated uplink radio resources. In the inactive mode the communication device performs no uplink transmission in the allocated uplink radio resources.
