FIELD: radio engineering, communication.
SUBSTANCE: invention provides methods and apparatus for scheduling positioning subframes, i.e. low interference subframes, to allow aligning of positioning subframes across multiple cells in order to reduce interference from data symbols of cells in the neighbourhood of a cell serving the UE that is performing positioning measurements. A time instance during which transmission of the positioning subframes is to occur in a wireless communication network is selected. The base stations in the wireless communication network are informed about the selected time instance, after which the base stations schedule and transmit the positioning subframes based on the selected time instance, whereby the positioning subframes are aligned throughout the network.
EFFECT: high accuracy of positioning.
