Abstract: There are provided measures for improvement of coverage hole analysis. Such measures exemplarily include detecting a radio link failure, producing a failure report including information indicative of a radio condition during a time period between said radio link failure and a successful establishment of a radio link, detecting said successful establishment of said radio link, and transmitting, after detection of said successful establishment of said radio link, said failure report.

Abstract: There are provided measures for uplink power control in heterogeneous network scenarios. Such measures exemplarily comprise include obtaining an upper limit value for a network configuration parameter, determining said network configuration parameter for said first cell on the basis of performance data of said first cell and said upper limit value such that said network configuration parameter does not exceed said upper limit value, and signaling said network configuration parameter for said first cell.

Abstract: There is provided a method and an apparatus for determining an adjustment of a tilt angle (α1, α2) for a beam emitted from an antenna (130) of a base station (100) which is serving a vertically sectorized cell (150) of a cellular radio telecommunication network. The method comprises (a) configuring user equipments (162, 164) being located in the vertically sectorized cell (150) with dedicated measurements, (b) collecting the dedicated measurements for a specific time interval, (c) obtaining a spatial user equipment distribution among a first sector (152) of the cell (150) and a second sector (154) of the cell (150) based on the collected dedicated measurements, (d) ascertaining an optimized spatial overlap region between the first sector (152) and the second sector (154) based on the obtained spatial user equipment distribution, and (e) determining the adjustment of the tilt angle (α1, α2) based on the ascertained optimized spatial overlap region.
