Abstract:
The present invention introduces methods and devices for provision of position determination assisting data as well as methods, devices and systems for performing position determinations based on this assisting data. The position determination assisting data comprises area definitions, each of which being related at least to a respective quantized path loss measurement index vector. Preferably, the vector is also dependent on relative radio conditions between different cells and/or transmission mode.
