  • Publication number: 20210212109
    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.

  • Patent number: 11039354
    Abstract: A User Equipment context is transferred from a source secondary network node to a target secondary network node. The UE is served by a master network node and the source secondary network node. The source secondary network node transmits, to the target secondary network node, a first message comprising a handover request, and receives a second message comprising configuration data of the target secondary network. After receiving the second message, the source secondary network node transmits, to the master network node, a third message comprising the configuration data of the target secondary network node.
