Channel state information (csi) feedback protocol for multiuser multiple input, multiple output (mu-mimo)

摘要: Certain aspects of the present disclosure provide techniques and apparatus for using channel state information (CSI) feedback multiuser multiple-input multiple-output (MU-MIMO) transmission. For certain aspects, a method wireless communications generally includes generating training frame transmitting generated frame. The typically first identifying group one or more apparatuses second indicating whether each in is to determine at least characteristic channel. other receiving request an transmitting, response received request, packet aggregation, wherein two frames are transmitted single transmission header.
