Methods and apparatuses for reduction of interference during positioning measurements

摘要

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.

主权项

1. A method in a radio network node, enabling reduction of interference in a wireless communications system in order to assist a user equipment in performing positioning measurements, the method comprising: receiving information comprising a set of signal quality measurements related to at least one signal of at least one interfering cell, from the user equipment being served by the radio network node; selecting a set of most interfering cells; and determining, for each interfering cell in the set of most interfering cells, a level of reduction of transmission activity of downlink signals, to be executed at a specific time and for a determined duration by a radio network node serving said at least one interfering cell; and before selecting the set of most interfering cells, rating the set of most interfering cells by their importance with respect to accuracy of the positioning measurements performed by the user equipment, based on the set of signal quality measurements related to each interfering cell.
