Carrier aggregation may be effected for a mobile terminal (50) in a cellular network environment between a carrier of a Frequency Division Duplex (FDD) system and a carrier of a Time Division Duplex (TDD) system. A receiver for one type of carrier will be susceptible to interference from a transmitter for the other type of carrier, but a parameter of the receiver of the one system and/or the transmitter of the other system may be set such that a non-zero throughput is achieved by communication of both the FDD and the TDD carriers. Base Station (10): Controller (15); FDD uplink receiver (21); FDD downlink transmitter (22); TDD uplink receiver (31); TDD downlink transmitter (32). Mobile Terminal (User Equipment) (50): Controller (55); FDD transmitter (61); FDD receiver (62); TDD transmitter (71); TDD receiver (72). FDD uplink signal (101); FDD downlink signal (102); TDD uplink signal (111); TDD downlink signal (112). Base station interference (122, 132); mobile terminal interference (121, 131). |
