Abstract
The invention relates to an improved method for dividing capable of listening broadcast control channel in wireless system of each channel of the base station (BTS1 to BTS3) according to the TDMA/FD-MA principle in one of the transceiver units the base station (BTS1 to BTS3) comprises establishing the wireless connection of the wireless unit in the wireless coverage range (MS1 MS2) of the device and device for transmitting broadcast control channel the system comprising at least two use the same predetermined frequency channel (F1) base station (BTS1 to BTS3) of the broadcast control channel. In order to reduce interference the base station (F1) of the predetermined frequency channel emitting power in the non-transmitted broadcast control channel time slot is adjusted to obtain than in transmitting the broadcast control channel time slot to be low. The invention also relates to a cellular radio system.
This invention relates to a method for improving the audibility of a broadcast control channel of a base station (BTS1 to BTS3) in a radio system in which transceiver units have been divided on the TDMA/FDMA principle into channels the base stations (BTS1 to BTS3) comprising means for establishing a radio connection to radio units (MS1 MS2) in their radio coverage area and means for transmitting a broadcast control channel whereby the system includes at least two base stations (BTS1 to BTS3) that have been arranged to transmit the broadcast control channel by utilizing the same predetermined frequency channel (F1). In order to reduce interference the transmission power of said predetermined frequency channel (F1) of the base station is adjusted lower in those time slots in which the broadcast control channel is not transmitted than it is in that or those time slots in which the broadcast control channel is transmitted. The invention also relates to a cellular radio system.
