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 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： When a node in a cellular communications network is serving a first User Equipment, it obtains information about a second UE that may be used as a relay by the first UE. It obtains information in the event that there is data to be sent to the first UE, and sends a request to a node serving the second UE.

摘要： Embodiments herein relate, e.g., to a method performed by a wireless device for handling communication in a wireless communication network. The wireless device transmits to a radio network node, a first preamble associated with a selected downlink beam. The wireless device further monitors for a random access response, RAR, in a first RAR reception window and when the RAR is not received in the first RAR reception window, monitors for the RAR in a second RAR reception window of a different beam or to transmit, to the radio network node, a second preamble associated with a second beam wherein the first preamble is associated with a channel state information reference signal and the second preamble is associated with a synchronization signal block.

摘要： According to certain embodiments, a target network node for communicating with a user equipment (UE) that was previously in communication with a source network node, comprises an interface operably coupled to processing circuitry. The interface is configured to receive a connection resume request from the user equipment, wherein the connection resume request comprises a resume identification associated with the source network node. The processing circuitry is configured to determine that the UE was previously in communication with the source network node. The interface is further configured to transmit the connection resume request to the source network node, receive a radio resource control (RRC) response from the source network node, and forward the RRC response to the UE.

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.

摘要： Embodiments include methods for a target node to establish a connection with a user equipment (UE) operating in dual connectivity (DC) with a PCell utilizing a first radio access technology (RAT) and with a PSCell utilizing a second RAT. Embodiments include receiving, from the UE, a re-establishment request message comprising parameters associated with the PSCell, a first message authentication code (MAC), and an indication of the UE's selection of a target cell served by the target node as a replacement for the PCell. The target cell utilizes the second RAT. Embodiments include verifying the message integrity based on the first MAC, and determining a full UE context based on the plurality of parameters associated with the PSCell and on a successful verification of the message integrity. Embodiments include establishing a connection with the UE based on the full UE context, whereby the target cell serves as a PCell for DC.

摘要： Systems, methods and apparatus are disclosed for user equipment and network nodes.An example method performed by a user equipment (UE) includes the UE detecting a failure relating to a connection between the UE and a Master Cell Group (MCG). The UE provides, to a master node via a Secondary Cell Group, SCG, a first message relating to the detected failure. The UE receives, from the master node via the SCG, a second message indicating to the UE to perform a connection reconfiguration.An example method performed by the master node includes the master node receiving, from the UE via the SCG, the first message including information relating to the detected failure of the connection between the UE and the MCG. The master node determines, based on the first message and a user equipment context, to perform a connection reconfiguration. The master node provides, to the UE via the SCG, the second message indicating to perform the connection reconfiguration.

摘要： A method and a wireless device (100) for handling handover in a wireless network (102) from a source cell (104) to a target cell when the device has obtained and stored a handover configuration for at least one target cell X (106A-C). Upon detecting a communication failure, the wireless device (100) performs cell selection and initiates handover to one of the target cell(s) X when that cell was selected, by applying the stored handover configuration of the selected cell. When none of the target cell(s) X was selected in the cell selection, the wireless device (100) initiates an RRC re-establishment procedure.
