Abstract
Method and an apparatus for determining the pathloss between a base transceiver station (BTS) and a mobile station (MS) in a mobile radio network. In detail, a signal carrier (BCCH) having a transmitting power (PTXAV) is transmitted by a first base transceiver station (BTS-1). Thereafter, said signal carrier (BCCH) transmitted by said first base transceiver station (BTS-1) is received by a mobile station (MS) spatially separated from said first base transceiver station (BTS-1), and the signal level (PTXAV) of the received signal carrier (BCCH) is detected by said mobile station (MS). Furthermore, the detected signal level (PTXAV) of said received signal carrier (BCCH) is transmitted to a second base transceiver station (BTS-2) of a neighboring cell. In addition, the detected signal level (PTXAV) of said signal carrier (BCCH) received by said mobile station (MS) is compared with the transmitting power (PTXAV) of said signal carrier (BCCH) transmitted by said first base transceiver station (BTS-1). A signal is then output which indicates the difference between these two signal levels, this difference being a measure of the pathloss, L, between said first base transceiver station (BTS…
