Abstract: A method (400) for dynamic RL. The method includes using an RL algorithm to select a first action and triggering performance of the selected first action. The method also includes after the first action is performed, obtaining a first reward value (R1) associated with the first action. The method also includes using R1 and/or a performance indicator (P1) to determine whether an algorithm modification condition is satisfied. The method further includes, as a result of determining that the algorithm modification condition is satisfied, modifying the RL algorithm to produce a modified RL algorithm. In this way, the RL algorithm adapts to changes in the environment.

Abstract: According to some embodiments, a method performed by a wireless device for handover in a non-terrestrial network (NTN) from a source cell to a target cell comprises receiving a conditional handover configuration for one or more potential target cells. The conditional handover configuration comprises a condition for handover comprising a timing advance threshold value for each of the one or more potential target cells. The method further comprises determining that a timing advance between the wireless device and one of the one or more potential target cells is less than or equal to the timing advance threshold and based on the determination, performing a handover to the target cell.

Abstract: A method for updating a tracking area in a non-terrestrial network comprises determining, at a network node, that a current tracking area in a non-terrestrial network is expiring; determining, at the network node, at least one target tracking area in the non-terrestrial network; and broadcasting, to at least one user equipment in the at least one target tracking area, system information comprising information of the at least one target tracking area. The target tracking area is determined based on a preconfigured mapping which comprises at least one target tracking area code corresponding to a cell identity of a target network node within a period of time or based on a movement of a satellite.

Abstract: A system, method and non-transitory computer readable media for facilitating reduced signaling load with respect to UE location reporting in a non-terrestrial network (NTN) environment (100) interoperable with one or more terrestrial cellular communications networks. In one embodiment of an index-based location reporting scheme, a UE (105, 1200) may receive (402) a list of reference locations from a network node (1000, 1100), each identified with an index. Responsive to receiving the list of reference locations, the UE (105, 1200) may report to the network node (1000, 1100) an index or a subset of indices of one or more reference locations that match a specific reporting criterion. In an example implementation, reporting of index-based location information by the UE (105, 1200) may be configurably triggered, e.g., periodically or in response to the occurrence of a particular event, condition, etc.

Abstract: A method for a user equipment, a method for a network equipment, a user equipment and a network equipment is disclosed. The network equipment transmits a signal pertaining to if control information is present in a first time period while the user equipment determines if a signal pertaining to control information is present in a first time period. The network equipment transmits control information to a UE in accordance with the transmitted signal while the user equipment decides whether to attempt to decode the control information depending on the determination.
