发明名称 Method and Arrangement for DL-OTDOA (Downlink Observed Time Difference of Arrival) Positioning in a LTE (Long Term Evolution) Wireless Communications System
摘要 The present invention relates generally to methods and arrangements for positioning in a wireless communications system, such as LTE. In particular, the present invention relates to improving positioning accuracy. The invention provides methods and arrangements for scheduling positioning subframes, i.e. low interference subframes, for allowing aligning of positioning subframes across a number of cells in order to reduce the interference from data symbols of cells in the neighborhood 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 communications network is selected. The base stations in the wireless communications network are informed about the selected time instance, whereupon the base stations schedule and transmit the positioning subframes based on the selected time instance, whereby the positioning subframes are aligned throughout the network.
