The method comprises applying an open-loop multi-stream transmission technique during an initial part of a transmission burst. In another step of the method, detailed channel state information is received (54). The detailed channel state information indicates transmission pre-coding to be used during the transmission burst when applying a closed-loop multi-stream transmission technique. The method further includes switching (55) from the open-loop multi-stream transmission technique to the closed-loop multi-stream transmission technique during the transmission burst, in response to receiving the detailed channel state information. The method is applicable to both uplink and downlink transmission bursts."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching between open and closed loop multi-stream transmission","description":"The present invention relates to a method and apparatus for multi-stream wireless communication between a transmitter node and a receiver node.
