  • Mobility robustness in a cellular network
    Patent number: 11005704
    Abstract: A user equipment starts a first timer in response to detecting a physical layer problem with a radio link between the user equipment and a node of a cellular network. Responsive to detecting a handover measurement event, the user equipment also starts a second timer and sends a measurement report to the node. The starting of the first and second timers causes the first and second timers to simultaneously elapse. Responsive to one of the simultaneously elapsing timers expiring, the user equipment sends a radio link failure report, to the node, indicating which of the simultaneously elapsing timers expired.

  • Methods and operations by network nodes and user equipments
    Patent number: 10966263
    Abstract: A UE operating in a RAN may be configured to receive new radio, NR, radio resource control, RRC, messages from a secondary network node. The NR RRC messages may each contain a number that the secondary network node added to the NR RRC messages to indicate their respective order in a sequence which the NR RRC messages were sent by the secondary network node. The NR RRC messages may each contain parameters that the UE uses to configure its communications through a NR interface with the secondary network node. The UE may send NR RRC complete messages toward the secondary network node responsive to receipt of the NR RRC messages, wherein the NR RRC complete messages each contain an indication of the NR RRC message that was received. The UE may control the sending of the NR RRC complete messages to indicate to the secondary network node whether the NR RRC messages are received in an order that is the same as the sequence.
