摘要： A method performed by a first network node for uplink congestion control in a radio network is provided. The first network node is operable to handle one or more first layers of a protocol stack for an uplink connection between a wireless device and the radio network and is communicatively coupled to a second network node handling one or more second, lower layers of the protocol stack. The method comprises obtaining an indication of a proportion of packets within an uplink user plane flow that are to be marked with a congestion indicator, in which the proportion is based on a delay experienced by packets of the uplink user plane flow sent by the wireless device to the second network node. The method further comprises marking the proportion of packets with the congestion indicator and transmitting packets for the uplink user plane flow towards a core network of the radio network.

摘要： A method performed by a first network node includes generating a data volume report based on one or more characteristics associated with data communicated between the first network node and a user equipment. The one or more characteristics identify that the data volume report is to be generated on at least one of a per Data Radio Bearer basis and a per Quality of Service basis. The data volume report is transmitted to a second network node. The data volume report further includes an indication of a radio access technology type associated with the data volume report.

摘要： The proposed technology generally relates to a method for controlling multi-point data transmission between a primary node (100) and a User Equipment, UE, via secondary nodes (101, 102). The method comprises the steps of obtaining (S1) Round-Trip Time, RTT, values ( T RTT, backhaul,i ) between a primary node (100) and two or more secondary nodes (101, 102). The method further comprises determining (S2) a time value relationship ( α i ) between uplink and downlink for each of the obtained RTT values; determining (S3) a first queue dwell time ( T ref, queue, 1 ) in a first secondary node (101 ) of the two or more secondary nodes (101, 102); and determining (S4) a second queue dwell time ( T ref, queue,2 ) in a second secondary node (102) of the two or more secondary nodes (101, 102), the second queue dwell time ( T ref, queue,2 ) being determined at least partly based on the RTT values ( T RTT, backhaul,i ), the time value relationship ( α i ) and the determined first queue dwell time ( T ref, queue, 1 ). The method further comprises initiating control (S5) of the first and second queue dwell times for synchronized data arrival in the UE.

摘要： A method performed by a first network node for downlink congestion control in a radio network. The first network node handles one or more first layers of a protocol stack for a downlink connection between the radio network and a wireless device, and is communicatively coupled to a second network node handling one or more second layers of the protocol stack for the downlink connection. The one or more second layers are lower than the one or more first layers. The method comprises: obtaining an indication of a proportion of packets within a downlink user plane flow over the downlink connection that are to be marked with a congestion indicator, wherein the proportion is based on a delay experienced by packets of the downlink user plane flow sent by the second network node to the wireless device; marking the proportion of packets with the congestion indicator; and transmitting packets for the downlink user plane flow to the second network node for onward transmission to the wireless device.

摘要： A method for transmission control in a multi-connectivity communication system comprises obtaining (S1) of an indication of decreased data rate through a first transmitting node of a multi-connectivity communication system. At least a subset of packets, originally scheduled for, and buffered in, the first transmitting node is rescheduled (S2) to at least one second transmitting node, different from the first transmitting node, of the multi- connectivity communication system, in response to the obtaining of the indication. A network node for transmission control is also disclosed.

摘要： The present disclosure relates to a method performed by a radio device. The method comprises receiving a plurality of Protocol Data Units (PDU) 41 of a PDU sequence 40 over a radio interface. The method also comprises detecting that a PDU 41b of the sequence of the received PDUs is missing. The method also comprises, for each of the received PDUs, identifying which Service Data Unit(s) (SDU) 51 it relates to. The method also comprises, based on said identifying, determining that a complete SDU 51b is obtainable from one or several PDUs of the received PDUs, which one or several PDUs are later in the sequence of the received PDUs than the missing PDU. The method also comprises obtaining the complete SDU from said one or several PDUs. The method also comprises performing a packet inspection of the obtained complete SDU to determine the type of data it carries. The method also comprises, based on the performed packet inspection, determining that the complete SDU fulfils a predetermined criterion. The method also comprises delivering the complete SDU which fulfils the predetermined criterion to a higher layer in the radio device, before receiving a retransmission of the PDU which is missing.

摘要： The invention discloses a method (400) for use in a wireless access network (100) with a number of cells (110), each cell being able to accommodate a number of user terminals (114), UE, the traffic to and from the UEs in a cell 5 being controlled by a node (112) in the system. Data packets can be exchanged between the UEs in a cell and the controlling node of the cell. The UEs can assume different states (210, 220, 230, 240) which have different capabilities such as data transfer speed, and according to the method of the invention, data packets which are sent to or from a UE (114) are analyzed 0 (410) in order to see if the UE should be transferred from one state to another, and in the UE may be instructed to change state as a result of the analysis.

摘要： Methods for dynamically triggering a Flow Control, FC, configuration change. The methods, which can be performed by a wireless device and/or a base station, involve determining whether there is a need to trigger the FC configuration change and triggering the FC configuration change in response to determining that the FC configuration change is needed. The FC configuration change includes switching between an FC activated state, in which FC and aggregation are enabled and Active Queue Management (AQM) is configured for a Packet Data Convergence Protocol (PDCP) Service Data Unit (SDU) buffer, and an FC deactivated state, in which FC and aggregation are disabled and AQM is configured for a Radio Link Control (RLC) SDU buffer. By dynamically triggering the FC configuration change, it is possible to enable FC and aggregation based on traffic volume on a Radio Bearer (RB) such that the benefit of aggregation can be realized when needed.

摘要： A method is provided by a central-unit-control plane (CU-CP) of a network node for exchanging information with a central-unit user plane (CU-UP) of the network node to manage Quality of Service (QoS) flows for the optimization of radio resources. The method includes transmitting, to the CU-UP, a request for flow information for at least one QoS flow and receiving, from the CU-UP of the network node, the flow information for the at least one QoS flow. Based on the flow information for the at least one QoS flow, at least one action is taken.
