摘要： A method performed by a first node (1811), for handling transmission of one or more packets from a sending node (1801) to a receiving node (1802) in a communications network (1800). The communications network (1800) comprises at least one intermediate node (1803) between the sending node (1801) and the receiving node (1802). The first node (1811) sends (1902) an indication to a second node (1812) in the communications network (1800). The indication explicitly indicates whether or not at least one of: a) to duplicate the one or more packets, and b) duplication of the one or more packets is supported and/or activated, over at least one of: i) a GTP layer, ii) one or more GTP tunnels, iii) a BAP layer and iv) over one or more Backhaul Radio Link Channels, between the first node (1811), and/or the second node (1812), and one or more next hop nodes (1804, 1805).

摘要： A method performed by a wireless terminal operating in Multi-Radio Dual Connectivity (MR-DC) and configured with a first cell group associated with a first network node and a second cell group associated with a second network node and a wireless terminal is provided. The method includes monitoring conditions and events for indicating that an operating mode of the second cell group should be modified. The method includes transmitting an indication to a network requesting a modification for the operating mode of the second cell group responsive to the monitoring indicating the operating mode of the second cell group should be modified. The method includes receiving a command from the network to change the operating mode of the second cell group. The method includes responsive to receiving the command, applying the command and start operating the second cell group in the indicated operating mode.

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： Systems and methods are disclosed herein that provide reporting of early measurements in a cellular communications system. Embodiments of a method performed by a wireless device are disclosed. Early measurements are also referred to herein as dormant mode measurements. In some embodiments, a method performed by a wireless device includes performing one or more dormant mode measurements, where the one or more dormant mode measurements are one or more measurements performed by the wireless device while the wireless device is in a dormant mode. The method further includes storing the one or more dormant mode measurements, identifying a reporting scheme to be used by the wireless device to report dormant mode measurements, and reporting at least one of the stored dormant mode measurements in accordance with the identified reporting scheme. Corresponding embodiments of a wireless device are also disclosed.

摘要： A method and apparatus for a first IAB node for securely communicating with at least one second IAB node is provided. A secure connection with a node of a network is established. A message is received, from the node, indicating a secure messaging protocol to use to communicate with the at least one second IAB node, the message including one of at least one nonce or a key. A control message to be sent to the at least one second IAB node is transformed into a secure control message using the secure messaging protocol. The secure control message is transmitted to the at least one second IAB node.

摘要： A method, system and apparatus are disclosed. According to one or more embodiments, a child IAB node is configured to communicate with a first parent IAB node and a descendant IAB node over a backhaul network. The child IAB node includes processing circuitry configured to: detect a backhaul link failure between the child IAB node and the first parent IAB node; in response to the detected backhaul link failure, cause transmission of a radio link failure indication to the descendant IAB node; receive signaling indicating for the child IAB node to connect to a second parent IAB node; and modify network topology at least in part by connecting to the second parent IAB node.

摘要： A method for inter-Radio Access Technology (RAT) handover comprises preparing, at a target node, a reconfiguration message based on that the target node is inter-RAT and intra-system to a source node, and sending, to the source node, the reconfiguration message for forwarding the reconfiguration message to a user equipment (UE). The reconfiguration message comprises configuration for reconfiguring lower layer at the UE and further keeps the UE from reconfiguring upper-layer configuration. The target node disclosed in the method prepares a reconfiguration message specific to different types of RAT combination and system between the source node and the target node to provide loss-less and in-order data delivery during and after the handover.

摘要： A method performed by a User Equipment (UE) for handing a Radio Link Failure (RLF) on a first group of cells in a wireless communication network is provided. The UE is engaged in an ongoing communication with the wireless communication network via a first group of cells and a second group of cells. The UE detects (501) that an RLF is on one or more out of the first group of cells. The further UE sends (502) a report to a network node in the wireless communication network. The report is sent via one or more out of the second group of cells while continuing the communication with the wireless communication network. The report comprises radio link information about the RLF on one or more out of the first group of cells.

摘要： Embodiments presented in this disclosure relate to methods and apparatuses (such as Access Points (AP's), evolved NodeB's (eNB's), etc.) for use in aggregation, or integration, between a Wireless Wide Area Network (WWAN) and a Wireless Local Area Network (WLAN). In one embodiment, an eNB decides that an aggregation between the WWAN and the WLAN is to be performed for at least one bearer of one or more bearers associated with a specific UE. Next, the eNB identifies which one(s) of the at least one bearer of the specific UE that is/are to be aggregated between the WWAN and the WLAN. Also, the eNB schedules each one of the at least one bearer identified to be aggregated between the WWAN and the WLAN.

摘要： Methods performed by wireless device for filtering relevant early measurement results are provided. Operations of such methods include obtaining multiple idle/inactive measurement results while the wireless device is in an idle/inactive state and transitioning from the idle/inactive state to an active state. Operations may include, responsive to transitioning from the idle/inactive state to the active state, selecting a subset of the idle/inactive measurement results based on capabilities of frequencies associated with idle/inactive measurement results to be used by the wireless device. Operations may further include transmitting the subset of the idle/inactive measurement results to a network node in a wireless communication network.
