US Patent 10111123 Relaxed measurement reporting with control plane dual connectivity

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.
