摘要： A method performed by a network node operating as an Integrated Access Backhaul (IAB) node includes determining at least two parent nodes within a multi-hop IAB network. The IAB node receives an uplink routing configuration associated with a cell group configuration that identifies a selected one of the parent nodes. Based on the uplink routing configuration associated with the cell group configuration, packets are sent to at least one of the at least two parent nodes.

摘要： A method performed by a Central Unit (CU) for assist in routing a data packet towards a UE is provided. The CU and the UE are operating in an Integrated Access 5Backhaul (IAB) communications network. Based on topology information for the IAB communications network, the CU determines (801) routes, between one or more IAB nodes and/or one or more Distributed Units (DUs) operating in the IAB communications network. The CU transmits (802) route information of the determined routes to the one or more IAB nodes and/or the one or more DUs. Each respective route information 10comprises a route identity and a respective node identity of the one or more IAB nodes and/or DUs comprised in the respective route.

摘要： A method (80) of performing transfer of data packets requiring a specified Quality of Service, QoS, by a User Equipment, UE, in an end-to-end, E2E, multi-hop sidelink radio communication (81). The UE comprises a processor operated protocol stack arranged for providing Physical, PHY, layer functionality, Media Access Control, MAC, layer functionality, Radio Link Control, RLC, layer functionality, and Adaptation, Adapt, layer functionality. The RLC layer functionality providing a plurality of ingress and egress RLC channels for transferring data packets. The method comprising receiving (83), by the RLC layer functionality, data packets a tan ingress RLC channel, mapping (84), by the Adapt layer functionality, data packets received at the ingress RLC channel to an egress RLC channel in accordance with a mapping rule for destining the data packets while maintaining the specified QoS, and transferring (86), by the RLC layer functionality, the mapped data packets at the egress RLC channel.

摘要： Embodiments herein relate to, for example, a method performed by a source radio network node (140), for handling communication in a wireless communications network, wherein the source radio network node is adapted to relay data packets between a first radio network node and a UE in the wireless communications network. The source radio network node (140) transmits to a target radio network node (150,12,15) a message relating to a cell selection and/or a handover for the UE, wherein the message comprises a first user plane indication, and wherein the first user plane indication is an indication of setting up a user plane communication or not for the UE.

摘要： Embodiments include methods for a source donor centralized unit (CU) in an integrated access backhaul (IAB) wireless network. Such methods include determining that traffic between the source donor CU and a top-level IAB node in the wireless network needs to be offloaded to a target donor CU in the wireless network. Such methods include sending, to one or more descendant nodes of the source donor CU, a first indication that at least one configuration for traffic between the source donor CU and at least one IAB node is suspended, in association with migration of the top-level IAB node from the source donor CU to the target donor CU. Other embodiments include complementary methods for a target donor CU and for an IAB node, as well as CUs and IAB nodes configured to perform such methods.
