Abstract
The exemplary embodiments of the present invention relate to methods and apparatuses enabling reduction of interference in a wireless system in order to assist a user equipment in performing positioning measurements. According to exemplary embodiments of the present invention, a radio network node is configured to: receive a measurement report from the UE comprising signal quality measurements related to interfering cells; to select a set of most interfering cells and to determine a level of reduction of transmission activity to be executed at specific time for a determined duration.

1-28. (canceled)
A method in a user equipment, for performing positioning measurements on at least three interfering cells, the method comprising:
- measuring a reference signal from the interfering cells;
- and, for each interfering cell
- detecting an absence of a positioning reference signal, PRS, indicative of a reduction in transmission activity from the interfering cells and
- switching from measuring positioning measurements on a positioning reference signal, PRS, to measuring on a cell-specific reference signal, CRS.
A user equipment, configured to perform positioning measurements on a at least three interfering cells, comprising:
- a measuring circuit, configured to measure a reference signal from the interfering cells;
- a detection circuit configured to detect, for each interfering cell, an absence of a positioning reference signal, PRS, indicative of a reduction in transmission activity from the interfering cells;
- the user equipment further comprising:
- a switching circuit configured to switch from measuring positioning measurements on a positioning reference signal, PRS, to measure on a cell specific reference signal, CRS, for each interfering cell;
- and
- the measuring circuit is configured to measure on a cell specific reference signal, CRS, for each interfering cell.
