摘要
An approach of handling interference caused by inter-modulation in a network node for wireless communication capable of communication with a set of stations for wireless communication is disclosed. The stations are wireless transceiver devices and communication from the network node to any of the stations is considered to be downlink communication performed on a downlink carrier in a downlink carrier frequency band and communication from any of the stations is considered to be uplink communication performed on an uplink carrier in an uplink carrier frequency band. The method comprises, when an interference level indicates probable inter-modulation interference, scheduling uplink transmission grants for a plurality of stations of a subset of the stations within a time interval, such that scheduling outside the time interval is reduced. The uplink transmission grants are valid for the time interval, wherein the scheduling uplink transmission grants is performed by adapting a schedule for at least one station of the plurality of stations of the subset of the stations to fall within the time interval. The method further comprises transmitting the uplink transmission grant to the plurality of stations of the subset of stations, assigning limited transmissions on the downlink carrier frequency band at the time interval such that inter-modulation interference is reduced on the uplink carrier frequency band during the time interval, and assigning transmissions on the downlink carrier frequency band outside the time interval with less limitations than during the time interval. The approach comprises methods, network nodes, computer programs and network node sites.
