The invention relates to a method of implementing transceiver operation at a base station. In the method, at least two transmitter units ( ) in different sectors transmit signals at different frequencies to the same multifrequency amplifier ( ), and the signals amplified by the multifrequency amplifier ( ) are transmitted to a filter structure ( ), which filters signals to be transmitted at different frequencies. In the method sector-specific antennas ( ) transmit and receive the signals at different frequencies and the filter structure ( ) filters the at least two signals received at different frequencies. The filtered signals are transmitted via the filter unit ( ) to the receiver amplifier ( ), whereupon the signals received from the different sectors are transmitted to sector-specific receiver amplifiers ( ).

Transceiver operation in radio system

A method for controlling a base station (,), used in a cellular radio system employing a TDMA multiple access method and having terminals (,), sectors (,) and at least one base station (,) which transmits one or more carriers, and which has a number of baseband parts (,), and at least one transmitter/receiver unit (,), and which is connected to the rest of the system by a digital transmission line (,) in which information is transmitted in timeslots. The timeslots are allocated as required to different carriers, the baseband parts (,) are allocated as required to different sectors (,) and the timeslots are allocated to different carriers so that one carrier will have no more than 16 timeslots.

Method for controlling a base station, and base station

A method of combining signals to a base station and combining signals in a radio network. The base station including an antenna, a modulating mechanism for generating and modulating carrier waves, and transmitters for generating signals that are modulated by the generated carrier waves. The signals are transmitted using an antenna. The modulating mechanism modulates two or more signals per generated carrier wave. The base station includes an amplification mechanism for amplifying the signals modulated by the carrier waves, and a mechanism configured to passively combine the signals modulated by the carrier waves to the same antenna after amplification.
