  • Patent number: 11968385
    Abstract: An object of the embodiments is to achieve an improved reference picture handling. That is achieved by taking into account whether the reference pictures in the decoded picture buffer are long-term reference pictures or short-term reference pictures when determining how they should be marked when the information of the reference picture set is received. The reference pictures are marked as “used for short-term reference” or “used for long-term reference” in the Decoded Picture Buffer (DPB) depending on whether they are included as short-term pictures or long-term pictures in the RPS of a current picture.

  • Patent number: 11968571
    Abstract: A method performed by a target node (111) in a communications network (100). The method is for handling reconfigurations of a User Equipment (UE) (120) during a conditional handover. The target node (111) has received a conditional handover request for the UE (120) from a source node (110) and has sent a handover request acknowledgement to the source node (110) based on a current configuration of the UE (120). The target node (111) performs (401) synchronization and random access with the UE (120) based on the UE configuration used for the handover request acknowledgement. The target node (111) obtains (403), after performing (401) the synchronization, information regarding an updated configuration of the UE (120). The updated configuration has taken place since the handover request acknowledgement was sent to the source node (110).

  • Patent number: 11968586
    Abstract: A network node of a wireless communication network provides information to a User Equipment (UE) that allows the UE to adapt it radio measurements with respect to the network, to account for “link changes.” Link changes are service-link and/or feeder-link changes arising from motion by the satellite(s) included in the Radio Access Network (RAN) portion of the network. The UE uses the provided information to adapt its radio measurements in conjunction with the link changes. Among the several advantages of accounting for satellite link changes in the manner contemplated are any one or more of reduced signaling going between the UE and the network, reduced battery consumption at the UE, mitigation of the effects of the link changes on the radio measurements, avoidance of spurious measurements, and an effective “automation” of the timed changeover by the UE to new measurement configurations, coincident with the occurrence of link changes.
