Abstract
An apparatus, method, system and computer program product is configured for avoiding base station self-interference due to transmit intermodulation in carrier aggregated communication systems. Physical downlink communication channels are allocated to respective component carriers per time interval according to a communication service in which communication is performed on an aggregation of component carriers of one or more frequency band such that component carriers to be used for transmission are separated from component carriers to be used for receiving by a transmit-receive-frequency gap band. However, not all available component carriers to be used for transmission are allocated in the same time interval. Rather, in each time interval, the physical downlink communication channels to be allocated for transmission are allocated to the available component carriers to be used for transmission such that, in each frequency band, the overall emission spectrum does not reach beyond the transmit-receive-frequency gap band.
