Abstract:
The present disclosure relates to the field of communication technology, and provides an information feedback method, an information feedback device and a UE. The information feedback method includes steps of: acquiring PMIs of multiple-level component precoding matrices of a precoding matrix for downlink data transmission; and feeding back the PMI of each of the multiple-level component precoding matrices of the precoding matrix to a base station individually, or feeding back the jointly encoded PMIs, each of which is the PMI of each of the multiple-level component precoding matrices of the precoding matrix, to the base station.

Claim (Index 30):
The information feedback device according to  claim 26 , wherein in the case that an identical User Equipment (UE) needs to feed back information to two base stations simultaneously, a first RI fed back to a first base station has a feedback priority level greater than a second RI fed back to a second base station, the second RI has a feedback priority level greater than the PMI 1  fed back to the first base station, the PMI 1  fed back to the first base station has a feedback priority level greater than the PMI 1  fed back to the second base station, the PMI 1  fed back to the second base station has a feedback priority level greater than the PMI 2  fed back to the first base station and a first CQI fed back to the first base station, the V-PMI 1  fed back to the second base station has a feedback priority level greater than the PMI 1  fed back to the first base station, and the PMI fed back to the first base station has a feedback priority level greater than the H-PMI 1  fed back to the second base station and the PMI 2  fed back to the second base station,\n wherein the first base station is a base station having a Multiple-Input Multiple-Output (MIMO) antenna array with controllable horizontal dimension antennas, and the second base station is a base station having an MIMO antenna array with both controllable horizontal and vertical antennas.
