A method for managing interference between i) a fixed wireless link, FL, formed by at least a first FL node and a second FL node which are configured to communicate wirelessly with each other at a first frequency and ii) a radio access network, RAN, node serving wireless communication devices, WCDs, the RAN node being able to use different beamforming configurations in transmitting different signals, and the RAN node being communicatively coupled to the first FL node through a communication channel, the method comprising: a) the first FL node monitoring radio link quality, Q L, of fixed wireless link signals received by the first FL node at the first frequency; b) the first FL node determining whether Q L is worse than a predetermined radio link quality threshold; in response to determining that Q L is worse than the predetermined radio link quality threshold: c1) the first FL node transmitting, to the RAN node over the communication channel, a request for the RAN node to transmit one or more signals in a silent period in which the second FL node is not transmitting any signal to the first FL node at the first frequency, the request identifying which one or more beamforming configurations the RAN node should use in transmitting the one or more signals; c2) the first FL node measuring, during the silent period, how much the one or more signals transmitted from the RAN node using the one or more beamforming configurations identified in the request interferes with the first FL node at the first frequency; and d) the first FL node providing interference measurement information to a controller (130a/130b/130c/130d/130e) configured to manage interference mitigation, wherein the interference measurement information indicates how much the one or more signals from the RAN node interferes with the first FL node at the first frequency, and the controller is configured to manage interference mitigation between the fixed wireless link and the RAN node based on the interference measurement information. a) the first FL node monitoring radio link quality, Q L, of fixed wireless link signals received by the first FL node at the first frequency; b) the first FL node determining whether Q L is worse than a predetermined radio link quality threshold; c1) the first FL node transmitting, to the RAN node over the communication channel, a request for the RAN node to transmit one or more signals in a silent period in which the second FL node is not transmitting any signal to the first FL node at the first frequency, the request identifying which one or more beamforming configurations the RAN node should use in transmitting the one or more signals; c2) the first FL node measuring, during the silent period, how much the one or more signals transmitted from the RAN node using the one or more beamforming configurations identified in the request interferes with the first FL node at the first frequency; and d) the first FL node providing interference measurement information to a controller (130a/130b/130c/130d/130e) configured to manage interference mitigation, wherein the interference measurement information indicates how much the one or more signals from the RAN node interferes with the first FL node at the first frequency, and the controller is configured to manage interference mitigation between the fixed wireless link and the RAN node based on the interference measurement information.
