摘要
A method performed by an apparatus is disclosed. The method comprises obtaining position information on a position and received signal strength information representative of a strength of a signal from a communication node receivable at the position. The method further comprises generating or updating a 3D sectorized path-loss model associated with the communication node at least based on the position information and the received signal strength information, wherein the position information and the received signal strength information are used to generate or update one or more path-loss parameters for a 3D sector of a set of one or more 3D sectors of the 3D sectorized path-loss model in which 3D sector the position is located. Furthermore, a method performed by an apparatus is disclosed, the method comprising, at least one of storing, providing or obtaining information on or derived from a 3D sectorized path-loss model associated with a communication node, the 3D sectorized path-loss model comprising one or more 3D sectors with one or more respective path-loss parameters, the information on or derived from the 3D sectorized path-loss model useable, together with received signal strength information representative of a strength of a signal received from the communication node by a device, in a process of determining an estimate of a position of the device. According apparatuses, computer programs and computer readable media storing such computer programs are disclosed.
