Abstract:
A method for determining the pathloss between a first base transceiver station (BTS-1) and a mobile station (MS) in a mobile radio network, said mobile station (MS) being spatially separated from said first base transceiver station (BTS-1) and a second neighboring base transceiver station (BTS-2); said method comprising the steps of:a) transmitting a signal carrier (BCCH) having a transmitting power (PTXAV) from said first base transceiver station (BTS-1); b) detecting the signal level (PRXAV) of said signal carrier (BCCH) transmitted by said first base transceiver station (BTS-1) after having been received by said mobile station (MS); c) transmitting the signal level (PRXAV) detected by said mobile station (MS) from said mobile station (MS) to said second base transceiver station (BTS-2); d) receiving the signal level (PRXAV) transmitted by said mobile station (MS) in said second base transceiver station (BTS-2); and e) comparing the transmitting power (PTXAV) of the signal carrier (BCCH) transmitted by said first base transceiver station (BTS-1) and the received signal level (PRXAV) transmitted from said mobile station (MS) with each other, thereby obtaining the pathloss between said first base transceiver station (BTS-1) and said mobile station (MS), wherein said pathloss measurement result is used to control the power of the BCCH carrier.
