METHODS AND DEVICES TO TRANSMIT CHANNEL STATE INFORMATION IN A MULTI-POINT WIRELESS COMMUNICATION SYSTEM

摘要

There is provided a method performed in a first network node, the first network node controlling at least one HSDPA radio link in a cellular communications network and the cellular network supporting HSDPA multiflow operation, the method comprises receiving CSI feedback at a receiving time instance and decoding the CSI feedback only if the receiving time instance and a first configured time instance coincide. The first configured time instance is based on a first cell specific parameter. The method finally determines whether the received CSI feedback is composite or non-composite.
