摘要： According to an aspect, a network node operating in a first RAN according to a first RAT receives a handover request for a user equipment from a cell in a second RAN operating according to a second RAT. After handover of the user equipment to a cell in the first RAN is completed, the network node configures the user equipment to measure frequencies corresponding to the second RAN. Based on measurements reported by the user equipment for the frequencies, the network node identifies detected cells exceeding a measurement threshold, and sends a handover report towards the second RAN. The handover report includes, for at least one detected cell exceeding the measurement threshold, a physical cell identifier and a frequency identifier for the detected cell. The network node obtains configuration information for the detected cell, from another node, and uses the obtained configuration information for subsequent mobility procedures.

摘要： A network node and a method performed by a network node for protecting control channels of a neighbouring RBS, the network node and the RBS being operable in an OFDM based radio communication network are provided. An RBS and a method performed by an RBS for transmitting control channels to UEs currently being associated with the RBS in an OFDM based radio communication network are also provided. The method in the network node comprises determining at least one subframe out of a predetermined number of subframes in which control channels are to be transmitted with reduced transmission power in relation to a nominal transmission power; and informing the RBS which subframe(s) out of the predetermined number of subframes in which control channels are to be transmitted with reduced transmission power.

摘要： In one aspect, a first device inserts, in a time synchronization Information Element (IE), location information for a transmitter associated with one or more cells, the location information indicating two or more transmitter locations for the transmitter. The first device transmits the time synchronization IE to a second device. The second device receives the location information in the IE indicating a location for the transmission point. The second device determines the two or more transmitter locations from the location information, determines an estimated location for the transmitter and an accuracy for the estimated location based on the two or more transmitter locations, and determines synchronization timing for transmissions based on a synchronization signal received from the transmitter, the estimated location, and the accuracy.

摘要： A node of a radio access network, RAN, receives (402), from a WLAN Termination, WT, an Extended Service Set Identifier, ESSID, and/or a Basic Service Set Identifier, BSSID, for one or more WLAN access points controlled by the WT. The node maintains (404) a mapping between the ESSIDs and/or the BSSIDs and corresponding WLAN access points of the WT. Responsive to receiving a measurement report from a UE, the measurement report indicating an ESSID and/or a BSSID, the node associates (406) the UE with a WLAN access point, based on said mapping. An interface may be established (408) between the node and the WT.

摘要： A wireless device, a network node, a core node and methods therein, for managing reachability of the wireless device. The wireless device starts an AS (Access Stratum) reachable timer when entering an inactive state. If the AS reachable timer expires while still in the inactive state, the wireless device sends to the network node a reachable notification indicating that the wireless device is reachable. If entering a connected state before the AS reachable timer expires, the wireless device stops the AS reachable timer when changing from the inactive state to a connected state. If the core node receives from the network node a not reachable notification indicating that the wireless device is not reachable, the wireless device can be marked as not reachable via paging.

摘要： Systems and methods for inhomogeneous slice support are provided. In some embodiments, a wireless device: signals an indication that it supports non-uniform slice availability and receives an information on how it may act based on the indicated slice support. In this way, some embodiments allow the Radio Access Network (RAN) and/or CN to correctly handle legacy and new UE types in a system where new UEs may be able to support non uniform slice availability. These may enable the CN to manage the legacy UEs in a way that their legacy behavior does not create unnecessary slice requests, e.g., for slices that are not available in a given cell. These systems and methods may allow new UEs to be configured with information for allowed slices that are not uniformly available, and that the UE may access upon detection of information expressing availability of such slices in a given cell/Tracking Area.

摘要： Systems and methods for handling of heterogeneous support for Slice Maximum Bit Rate (S-MBR) enforcement are disclosed. In one embodiment, a method performed in a core network of a cellular communications system comprises, at an Access and Mobility Management Function (AMF), obtaining information about whether a Radio Access Network (RAN) node supports S-MBR enforcement and sending, to a Session Management Function (SMF), a message that comprises an indication of whether the RAN node supports S-MBR enforcement. The method further comprises, at the SMF, sending, to a Policy and Control Function (PCF), a message that comprises an indication of whether the RAN node supports S-MBR enforcement. The method further comprises, at the PCF, making a determination of whether to apply a mechanism to enforce S-MBR for Protocol Data Unit (PDU) session of a wireless communication device on a network slice based on the received indication, and operating accordingly.

摘要： Embodiments include methods for beam-level mobility load balancing, MLB, in a radio access network, RAN. Optionally, such methods include receiving (1810) measurement reports from a plurality of user equipment, each measurement report comprising radio measurements related to a source beam associated with a source node and target beams associated with one or more target nodes. Such methods include exchanging (1820) beam-level load information with the target nodes and, based on the beam-level load information and (optionally) the reports, selecting (1830) one or more target beams, associated with a particular target node, for MLB operations with the source beam. Such methods include transmitting (1840), to the particular target node, a request including one or more handover offsets to be applied during MLB operations between a group of source beams associated with the source node, including the source beam, and a group of target beams associated with the particular target node, including the selected target beams.
