There is provided a method of handling interference caused by inter-modulation in a network node site comprising a set of network nodes for wireless communication capable of communication with a set of stations for wireless communication. The stations are wireless transceiver devices and communication from the network node to any of the stations is considered to be downlink communication and communication from any of the stations is considered to be uplink communication. The method comprises detecting likely passive intermodulation, determining at least one station having an uplink resource being a likely to be affected by the detected likely passive intermodulation, and limiting downlink transmission, when the determined at least one station is scheduled or expected to transmit on the uplink resource, on a downlink resource likely to be affecting the uplink resource by the detected likely passive intermodulation. A computer program, a controller and a network node site are also disclosed.

Method and apparatus for handling interference caused by inter-modulation

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.

The present application relates to methods and devices for handling a link in a cellular network environment. A method for handling a link between a network and a mobile terminal is provided. The network comprises a first base station serving the terminal and a second base station. The method comprises the steps: determining a mobility of the terminal; determining location information of the second base station; on the basis of the determined mobility and the location information, selecting a procedure to handle the link; and initiating to perform the selected procedure. One aim is to improve the quality of the link. A corresponding apparatus is also provided.
