摘要： There is provided a method of handling interference caused by inter-modulation in a network node. The method comprises detecting an interference level on an uplink carrier frequency band for stations, and determining whether the interference level indicates probable inter-modulation interference. If the interference level indicates probable inter-modulation interference, the method proceeds with scheduling an uplink transmission grant for at least one of the stations. The uplink transmission grant is valid for a first transmission time interval. The uplink transmission grant is transmitted to the station. A transmit level on the downlink carrier frequency band is assigned at the first transmission time interval such that inter-modulation interference is reduced on the uplink carrier frequency band at the first transmission time interval. An uplink transmission from the station is received at the first transmission time interval. Further methods, computer programs, a network node and a network node site are also disclosed.

摘要： A down-conversion circuit for a receiver circuit is disclosed. It comprises a first mixer arranged to down-convert an RF signal with a first LO signal (LO1), thereby generating a first down-converted signal. It further comprises a second mixer arranged to down-convert the RF signal with a second LO signal (LO2) having the same LO frequency as the first LO signal (LO1), but a different and a second duty cycle, thereby generating a second down-converted signal. The second mixer has an enabled and a disabled mode. The down-conversion circuit also comprises a third mixer arranged to down-convert the RF signal with the second LO signal (LO2), thereby generating a third down-converted signal. A passive output combiner network is used to combine the first and the second down-converted signals such that harmonically down-converted signal content present in the first down-converted signal and harmonically down-converted signal content present in the second down-converted signal cancel in a combined output signal of the down-conversion circuit. The down-conversion circuit further comprises a detection unit adapted to detect interference based on the first and third down-converted signals and to selectively set the second passive switching mixer in the enabled mode, for counteracting the interference, or in the disabled mode, for saving power compared with the enabled mode, based on the detection. A corresponding receiver circuit, a corresponding communication device, and a corresponding method are also disclosed.
