Patent ID: 8094579

Claim:
A controlling node for a cell in a cellular communications system, the controlling node comprising: a measurer, implemented by a central processing unit executing computer-readable instructions stored on a non-transitory computer-readable storage medium, for measuring, to measure a performance indicator of the communication between the node and at least one user in the cell, wherein the performance indicator is measured as the amount of data bits successfully transferred in data blocks in at least one direction, uplink and/or downlink, between the controlling node and at least one user during said defined amount of time, divided by the number of smallest physical resources in the system in terms of time and frequency which have been used for said successful transfer of the data bits during said defined amount of time; an aggregator, implemented by the central processing unit executing computer-readable instructions stored on the non-transitory computer-readable storage medium, to aggregate the measured performance indicator for said at least one user over a defined amount of time; and an excluder, implemented by the central processing unit executing computer-readable instructions stored on the non-transitory computer-readable storage medium, to exclude from said aggregated measurement one or more predefined combinations of one or more data blocks and one or more said smallest physical resources in the system.
