Abstract

In order to control the transmitting power provided for point-to-multipoint telecommunications links in a telecommunications system with wireless telecommunication and uncoordinated unlicensed system operation, without significant restriction of the transmitting range, use is made of the fact that the maximum number of mobile stations (MS1 . . . MSn) registered in a base station (BS1) is known. Thus, the base station knows at any time how many and which mobile stations are registered. If all mobile stations are registered (NACT=NSCHED), the base station can match the transmitting power to the mobile station received as the “weakest one”. In other cases, if not all mobile stations are registered (NACT≠NSCHED), the base station will alternately transmit with the maximum transmitting. power for a predetermined first period of time and then with the reduced transmitting power, which matches the mobile station received as the “weakest one”, for a predetermined second period of time.
