Abstract: A method for transmission reliability comprises receiving, from a first network node at a second network node, a message indicating that a first connection between the first network node and a terminal device has failed. The message comprises an indication to initiate a second connection with the terminal device from the second network node. The method further comprises establishing, at the second network node, the second connection with the terminal device based on the message. The second network node comprises a third connection established before the first connection failed. The first connection carries data transmitted in the third connection before the first connection failed, and the second connection carries data transmitted in the third connection after the first connection failed. The method for interference coordination utilizes duplicated transmissions to secure data transmission and to prevent data loss in an unexpected system failure.

Abstract: A method of operating a UE to provide feedback on a streaming session. The method includes determining when a streaming session used by an application layer of the UE is being started and/or ended. Responsive to the determination, the method transmits an indication to a RAN that the streaming session is being started and/or ended. A corresponding method of operating a network node is provided to control reporting relating to streaming sessions of UEs. The method by the network node receives an indication from an UE that a streaming session is being started and/or ended, and controls whether a Quality of Experience (QoE) configuration file is sent to the UE responsive to the indication.
