| 摘要 |
The invention relates to a method of implementing transceiver operation at a base station. In the method, at least two transmitter units (300, 302) in different sectors transmit signals at different frequencies to the same multifrequency amplifier (306), and the signals amplified by the multifrequency amplifier (306) are transmitted to a filter structure (500), which filters signals to be transmitted at different frequencies. In the method sector-specific antennas (418, 420) transmit and receive the signals at different frequencies and the filter structure (500) filters the at least two signals received at different frequencies. The filtered signals are transmitted via the filter unit (400) to the receiver amplifier (404), whereupon the signals received from the different sectors are transmitted to sector-specific receiver amplifiers (406, 408). |
