Abstract: Methods and apparatuses for handover between different radio access technologies (RATs) are disclosed. According to an embodiment, an access network node receives, from a mobility management entity (MME), information indicating that one or more bearers for a terminal device cannot be handed over to one or more RATs different than long term evolution (LTE). The access network node determines whether to perform a packet switched (PS) handover for the terminal device based on the information.

Abstract: A method, system and apparatus are disclosed for handling Quality-of-Service (QoS) updating during handover (HO). In one embodiment, a network node is configured to during a handover, HO, procedure associated with a wireless device, WD, receive a path switch request acknowledgement message comprising at least one first Quality-of-Service, QoS, parameter value associated with the WD; and as a result of the received path switch request acknowledgement message comprising the at least one first QoS parameter value, use at least one second QoS parameter value associated with the WD and send a notification, the notification indicating at least one of: that the at least one first QoS parameter value is not fulfilled, that a QoS parameter updating is not supported by the network node and that the QoS parameter updating failed.

Abstract: Methods and apparatuses are disclosed for location reporting. A mobility management node determines to establish a connection between the mobility management node and a terminal device for which location reporting is required. The mobility management node sends, to a base station, a request for establishing the connection. The request is configured to request the base station to report location information of the terminal device.

Abstract: A method for interference coordination comprises receiving, from a first network node, a reference signal indicating that one or more second network nodes are experiencing interference. The reference signal indicates at least one identifier for the first network node and for the second network nodes. The method further comprises preparing a remote interference management (RIM) coordination message based on the reference signal, and sending, to the first network node, the RIM coordination message to be forwarded to the second network nodes. The method provides a communication between a central aggressor network node and a central victim network node to exchange reference signal and RIM coordination information. Furthermore, the central victim network node may pass the RIM coordination message to a group of victim network nodes indicated in the RIM coordination message.

Abstract: Embodiments include methods performed by a source node for handover of a user equipment (UE) from a source cell served by the source node in a wireless network. Such methods include transmitting, in the source cell according to a reference time delivery configuration, one or more messages that include respective reference times in relation to corresponding source cell transmission events. Such methods also include transmitting, to a target node in the wireless network, the reference time delivery configuration in relation to a request to handover the UE from the source cell to a target cell served by the target node. Other embodiments include complementary methods performed by the target node, as well as network nodes configured to perform such methods.

Abstract: Embodiments herein relate to e.g. a radio network node (12) for handling an update of a protocol data unit, PDU, session, for a wireless device (10) in a wireless communication network (1). The radio network node (12) is configured to transmit to a network node (13), an indication indicating one or more quality of service, QoS, flows or PDU sessions to be released. The radio network node (12) is further configured to receive a confirmation indication from the network node (13), wherein the confirmation indication indicates one or more QoS flows or PDU sessions released and/or not released; and to handle the update of the PDU session based on the received confirmation indication.

Abstract: A method of operating a network node to provide dual connectivity in a new radio telecommunications system. The method allocates two tunnel endpoint identifiers (TEIDs). The method sends the allocated TEIDs to at least one other network node for transporting a Protocol Data Unit (PDU) session that can be split. The method receives two TEIDs for a master node and a secondary node (SN). A related method of operating a master node provides dual connectivity. The method sends a SN addition request message to a SN. The method sends a SN add/modify completion indication to the SN that informs the SN that the operations to add/modify are complete.

Abstract: Disclosed herein is a method for interference coordination in a split gNB architecture. The method includes receiving at a central unit gNB one or more messages from one or more distributed units. Each message that is received comprises an identification of the distributed unit that sent the message and an identification of a victim distributed unit that experienced interference. The method further includes merging the one or more messages into single merged message. The method additionally includes sending the merged message to at least the victim distributed unit.

Abstract: Systems, methods, and apparatus for reporting a Downlink Data Delivery Status (DDDS) are disclosed herein. An example method includes a network node generating a DDDS frame including an indicator that a highest transmitted Packet Data Convergence Protocol (PDCP) Packet Data Unit (PDU) sequence number is present in the DDDS frame, an indicator that a highest successfully delivered PDCP PDU sequence number delivered is present in the DDDS frame, a desired buffer size for a data bearer, the highest transmitted PDCP PDU sequence number, and the highest successfully delivered PDCP PDU sequence number. The network node provides the DDDS frame to a second network node.
