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.

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: The present invention provides apparatuses, methods, computer programs, computer program products and computer-readable media regarding signaling physical cell identifier problems. Certain aspects of the present invention include receiving, at a network node, information regarding a suspected identifier problem from a first base station, the information indicating the suspected identifier problem between the first base station and a second base station, and analyzing the suspected identifier problem based on the received information.

Abstract: Systems and techniques for antenna optimization are described. Information such as statistics relating to conditions are collected, and evaluated against specified criteria in an iterative process. An antenna tilt decision is made based on the evaluation and validated to determine if it should be retained or repeated, or if the tilt should be returned to a previous state.
