Channel state information feedback frame format and feedback rules for very high throughput wireless systems

摘要: Certain aspects of the present disclosure provide techniques and apparatus for generating a unified format channel state information (CSI) feedback Very High Throughput (VHT) wireless systems. One example method generally includes generating, at first apparatus, frame comprising relating to SNR if second is communicating with using single-user MIMO (SU-MIMO) or multi-user (MU-MIMO) transmitting signal based on generated apparatus. Another an structure CSI, wherein CSI one matrix estimates associated obtained singular value decomposition (SVD) further comprises indication which matrices included in CSI; over channel.
