INTER-FREQUENCY MEASUREMENTS FOR OBSERVED TIME DIFFERENCE OF ARRIVAL

摘要

Aspects of this invention include a method, system and computer program to perform mobile node measurements. In a method there are steps of receiving from a location server at a mobile user node a request to perform inter-frequency reference signal time difference measurements; receiving from a serving access node a measurement gap configuration; performing the requested inter-frequency reference signal time difference measurements during the assigned measurement gaps; and reporting the results of the inter-frequency reference signal time difference measurements to the location server.
