Abstract (en)
[origin: WO2022157462A1] The invention relates to a method for transmitting a downlink reference signal (PRS1, PRS2) from a network entity (DU) to a mobile terminal (1) via a radio unit (RU) connected to an antenna, used to geolocate the mobile terminal (1), the method being implemented by the radio unit (RU) and comprising: - receiving the reference signal (PRS1, PRS2) from the network entity (DU) and destined for the mobile terminal (1), and - transmitting the reference signal (PRS1, PRS2) to the mobile terminal (1) upon expiry of what is termed a delay period with respect to the transmission time of the reference signal by the network entity (DU), the delay period having a value greater than a transmission travel time of a signal termed a comparison signal (S1, S2) between the network entity (DU) and the radio unit (RU).
