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: 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: Methods, apparatus and computer program products are disclosed for enhancing mobility robustness optimization in self optimizing networks. Neighbor relation information indicating relations between a handover source cell and candidate handover target cell(s), each including a first counter indicating events of an unsuccessful handover of a user equipment from the handover source cell to one candidate handover target cell, and a second counter indicating events of connection re-establishment attempt of the user equipment to the candidate handover target cell after an unsuccessful handover to another cell. A first candidate handover target cell to which handover of the user equipment was unsuccessful and a second candidate handover target cell to which the user equipment has re-established a connection, out of the candidate handover target cells, are determined. The first counter and/or the second counter of the neighbor relation information concerning the determined first and second candidate handover target cells is updated.
