The central network node receives a first Channel Quality Indicator, CQI, and a third CQI sent by the first wireless device. The first CQI has been computed by the first wireless device based on a first unique signal transmitted by the first network node. The third CQI has been computed by the first wireless device based on a second unique signal transmitted by the second network node. The central network node identifies the one of the first and the second network nodes having a better channel quality, based on the received first CQI and the third CQI. The central network node sends a first message to the identified network node, instructing it to transmit to the first wireless device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Central network node, first network node, first wireless device, controller network node, and methods therein, of instructing the first network node to transmit to the first wireless device","description":"A method performed by a central network node includes instructing one of a first network node and a second network node to transmit to a first wireless device.
