摘要： A method performed by a network node for preventing a release of a connection from a User Equipment, UE, to the network node, which connection uses a Real Time Protocol, RTP, for media transfer. The network node operates in a wireless communication network and serves the UE. The network node detects a gap in a packet- flow of the connection. When the network node has detected a gap in the packet flow, the network node prevents the UE from initiating a release of the connection caused by the gap in the packet flow, by sending a message to the UE, which message forces the UE into a failure. The failure triggers the UE to initiate a Radio Resource Control, RRC, Connection Reestablishment procedure.

摘要： A method for evaluating a connection between a first network node and a User Equipment, UE, via a Second Cell is provided. The first network node serves a first cell. A sending of a first message is initiated (302). The first message is sent from the first network node to the UE via the second cell. The first message comprises a trigger for the UE to respond by sending a second message comprising feedback relating to the connection to the second cell. A time value difference between the sending of said first message and receiving (304) of said second message in the first network node is obtained (305). The second message comprises the feedback relating to the connection sent from the UE in response to the first message. Then it is evaluated (306) how the connection shall be used based on the obtained time value difference and the received feedback.

摘要： There is provided mechanisms for CSI reporting on protocol layer 2. A method is performed by a wireless device. The wireless device is served by an access network node on a serving beam. The wireless device is configured with event conditions as to when to provide the CSI reporting to the access network node and with reporting configuration as to how to provide the CSI reporting to the access network node. The method comprises obtaining CSI values by monitoring candidate beams in which reference signals are transmitted by the access network node. The method comprises determining, based on comparing the CSI values to the event conditions, that at least one of the event conditions for CSI reporting is fulfilled. The method comprises sending the CSI reporting to the access network node as a protocol layer 2 CSI report and in accordance with the reporting configuration.

摘要： Embodiments include methods for determining a movement state of a user equipment (UE)operating in a radio access network (RAN). Such methods include performing positioning measurements on signals received from a plurality of transmission points (TPs) in the RAN, including first measurements of Doppler shift of signals from a first TP, second measurements of Doppler shift of signals from a second TP that is spatially separated from the first TP, and third measurements of signals from a third TP. The third TP can be the same as the first or second TP, or spatially separated from both. Such methods include determining a UE movement state based on the positioning measurements and an interacting multiple-model (IMM) that includes a first almost-constant velocity model, a second maneuver velocity model, and a Doppler shift bias state common to the first and second models. Other embodiments include complementary methods for a RAN node.

摘要： A method for arranging transmission of SSBs comprises transmitting (S1), from a first TRXP of a cellular telecommunication system, of first SSBs at a carrier. The first SSBs define a first cell. The first cell is unique for the first 5TRXP. The method further comprises transmitting (S2), from the first TRXP, of second SSBs at the carrier. The second SSBs define a second cell. The second cell is a combined cell of the first TRXP and at least one neighbouring, second TRXP. A method for cell assignment based on multiple SSBs is also disclosed, as well as TRXPs and network nodes for implementing the methods.

摘要： In some embodiments, a network node (e.g., a base station) collects information pertaining to components that form a Maximum Received Timing Difference (MRTD). For instance, the network node determines TAE. The network node then evaluates, for a particular UE, whether a certain MRTD requirement (MRTDR) for a specific coordinated service (CS) can be fulfilled. If the requirement can be met, then the network node may initiate the specific CS for the UE (or continue providing the CS), and if the requirement cannot be met, then the network node may stop or modify the CS for the UE.

摘要： Methods and related wireless device and radio network node, which enable the handling of Quality of Experience, QoE, measurements during handover, are described. In some aspects, the wireless device may determine whether to report QoE measurements and whether to start new QoE measurements, in a cell served by a target radio network node, based, at least in part, on the presence or absence of QoE-measurement related indications in the handover command message received from the target radio network node.
