| titleOfInvention | Channel information feedback method and device in mobile communication system |
| abstract | The invention provides a method for feeding back channel state information in a large-scale multi-input multi-output system. In one embodiment, the method comprises: the UE detects a plurality of downlink reference signal ports, and the feedback part feeds back the indexes of the reference signal ports with better channel quality to assist the uplink receiving precoding operation. By using the technical scheme provided by the invention, the problem of CSI feedback in a Massive MIMO system is solved, the problem of pilot pollution is avoided by supporting uplink receiving precoding, in addition, the calculation complexity required by uplink channel estimation is greatly reduced, and simultaneously, the compatibility with the existing system is maintained to the greatest extent. |
