1. A method performed by a network node, comprising:
selecting a serving beam for a terminal device from candidate beams reported to the network node by the terminal device, based at least in part on inter-cell interference information of the candidate beams; and
informing the terminal device of the selected serving beam, and
wherein the inter-cell interference information of the candidate beams is based on an evaluation of inter-cell beam interference for the network node, wherein the evaluation of the inter-cell beam interference for the network node comprises:
performing measurement configuration for one or more reference devices which are potentially subject to inter-cell beam interference, wherein the measurement configuration instructs the one or more reference devices to report neighboring cell measurement information to the network node in response to a trigger event;
receiving the neighboring cell measurement information reported by the one or more reference devices in response to the trigger event, wherein the neighboring cell measurement information indicates potential inter-cell interferers of beams reported to the network node by serving cell measurement information of the one or more reference devices; and
evaluating the inter-cell beam interference, based at least in part on the neighboring cell measurement information reported by the one or more reference devices.
