Abstract:
1. A method in a network node with positioning functionality in a wireless communications network in a multi-carrier system with carrier aggregation, each aggregated carrier corresponding to a component carrier, to enable UTDOA, Uplink Time Difference of Arrival, positioning measurements for a wireless device in the multi-carrier system, the method comprising the steps: obtaining multi-carrier capability of a radio node capable of performing UTDOA positioning measurements, receiving interference or load related information for multiple component carriers at the radio node performing UTDOA positioning measurements in the multi-carrier system that are supported for UTDOA positioning measurements; and selecting at least one of the multiple component carriers for UTDOA positioning measurements on radio signals transmitted by the wireless device based on said interference or load related information.
