Switching between open and closed loop multi-stream transmission |
摘要 |
The present invention relates to a method and apparatus for multi-stream wireless communication between a transmitter node and a receiver node. 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.
