Method and apparatus for handling interference caused by inter-modulation

A non-transitory computer readable medium comprising a computer program comprising instructions which, when executed on a processor of a controller at a network node site, cause the controller to perform a method of handling interference caused by inter-modulation in the network node site, wherein the network node site comprises a set of network nodes for wireless communication with a set of stations, and wherein the set of stations are wireless transceiver devices and communication from a network node of the set of network nodes to any of the set of stations is considered to be downlink communication and communication from said any of the set of stations is considered to be uplink communication, the method comprising:

• detecting likely passive intermodulation;
• determining at least one station of the set of stations having an uplink resource being 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, wherein limiting the downlink transmission comprises adapting any one or more of:
• scheduled content to transmit;
• and resource block assignment for the downlink transmission.

A controller arranged to operate with a network node site comprising a set of network nodes for wireless communication with a set of stations, wherein the set of stations are wireless transceiver devices and communication from a network node of the set of network nodes to any of the set of stations is considered to be downlink communication and communication from said any of the set of stations is considered to be uplink communication, and wherein the controller comprises a processor configured to:

• detect likely passive intermodulation;
• determine at least one station of the set of stations having an uplink resource being likely to be affected by the detected likely passive intermodulation;
• and
• limit 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, wherein, to limit the downlink transmission, the processor is configured to adapt any one or more of:
• scheduled content to transmit;
• and resource block assignment for the downlink transmission.
