Abstract:
1. A method in a base station, for sending a value of a propagation delay of a signal sent to the base station from a user equipment that is associated with a location point, the base station and the user equipment are comprised within a wireless communication system and are adapted to exchange wireless signals, the method comprising the steps of: receiving a signal sent from the user equipment, associated with the location point; measuring the value of the signal propagation delay of the received signal; determining magnitude of a position change of the user equipment and/or speed of the user equipment; and sending the measured value of the signal propagation delay from the base station to the user equipment and/or to a positioning node comprised within the wireless communication system, wherein the step of sending the measured value of the signal propagation delay from the base station to the user equipment and/or to the positioning node is performed at a periodicity which is determined based on the determined magnitude of the position change of the user equipment and/or speed of the user equipment, wherein the received signal comprises a first received signal, wherein the measured value of the signal propagation delay comprises a first measured value of a first signal propagation delay, and wherein the method further comprises:
