ABSTRACT:
The present invention relates to a method and an arrangement in a mobile telecommunication network for detection of a UE transmitted signal. The arrangement comprises means for detecting the signal during the time ttot, wherein said means comprises a correlator adapted for combined coherent and non-coherent correlation, wherein the length of the coherent correlation interval is L signal samples, the number of coherent correlation intervals is M and the coherent correlation results in a coherent correlation result for each of the coherent detection intervals M, and means for adding the coherent correlation results non-coherently. Further, the arrangement comprises means for selecting one of the length L of coherent detection interval and the total detection interval ttotbased on at least one of the parameters cell size, UE speed and acceleration, number of participating Location Measurements Units and a desired total false alarm rate.
