The method comprises acquiring a speed category for a user device of the plurality of user devices and controlling the MU-MIMO operation in relation to the user device based on the speed category. In some embodiments, controlling the MU-MIMO operation in relation to the user device based on the speed category comprises one or more of: controlling reference signal transmission for the user device based on the speed category and controlling MU-MIMO group affiliation of the user device based on the speed category. In some embodiments, controlling reference signal transmission for the user device based on the speed category comprises controlling a duration of a time interval between subsequent reference signal transmissions for the user device based on the speed category. Corresponding apparatus and network node are also disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"MU-MIMO operation control","description":"A method is disclosed for multi-user multiple-input multiple-output (MU-MIMO) operation of an access node serving a plurality of user devices.
