    Abstract: Small base station, micro, femto or pico BTS (PBS) are connected via Un interface to a donor eNB DeNB. In case of a handover from that PBS packets that had not been acknowledged by a UE need to be forwarded to the target base station. Forwarding them via Un and DeNB to the target eNB causes latency and wast radio resources on Un. Thus, the DeNB uses information about the handover to buffer packets and, after being informed by PBS, forward those packets that had not been acknowledged by the UE. This procedure, therefore, saves resources on Un interface and reduces latency. No forwarding of those packets from PBS to DeNB is required. There is provided a method for forwarding data to a wireless terminal. The method is performed by a proxy node. The method comprises receiving data on a link between a core network and a backhaul hub node. The data is addressed to a wireless terminal served by, or handed over from, a serving network node. The method comprises receiving a first indication to forward the data to a target network node of the wireless terminal. The method comprises forwarding the data towards the target network node in response thereto. There is also provided a computer program for such a method and a proxy node configured to perform such a method.

    Abstract: The disclosure relates to a method in a wireless device for transmitting an uplink signalling message in a wireless communication network. The wireless device is connected to a first network element over at least a first and a second wireless link. The method comprises determining a transmission mode among alternative transmission modes for transmitting the uplink signalling message. The alternative transmission modes comprise: transmitting on the first wireless link; transmitting on the second wireless link; and transmitting on both the first and the second wireless links. The method also comprises transmitting the uplink signalling message according to the determined transmission mode. The disclosure also relates to a corresponding method performed in the network element, and to the corresponding apparatus.

    Abstract: The disclosure relates to reporting measurements and in particular to relaxed measurement reporting when the wireless device is using multiple radio links for the control plane. The disclosure relates to methods of reporting measurement and of controlling reporting of measurements, as well as to devices and computer programs configured thereto. According to some aspects the disclosure relates to a method, performed in a wireless device in a wireless communication system, for reporting measurements. The method comprising receiving S1, from a radio network node, information defining at least one further measurement report setting for measurement reporting in a control plane multi connectivity mode; wherein the at least one further measurement report setting corresponds to a more relaxed measurement reporting than a first measurement report setting for measurement reporting in a control plane single connectivity mode, which is available to the wireless device, selecting S2 one of the first and further measurement report settings based on a determination of a control plane connectivity mode of the wireless device; wherein the wireless device is in the control plane multi connectivity mode when the wireless device is using multiple radio links for the control plane and reporting S4, to the radio network node, measurements in accordance with the selected measurement report setting.

    Abstract: There is provided means for connecting a client node to a hub node in a wireless backhaul network. Network related operations, administration, and maintenance (OAM) system information is acquired by the client node. A wireless connection is established by the client node to a hub node. The hub node is selected based on the acquired OAM system information. A start up procedure for connecting the client node to the hub node is thereby provided.
