Abstract
Method and user equipment (UE) are provided for CSI compression based on multi-dimensional MIO RF signature. In one novel aspect, the UE receives CSI-RS, estimates a basis matrix and a coefficient matrix of a downlink channel matrix based on the at least one CSI-RS, wherein the basis matrix is an N-dimensional non-orthogonal matrix, with N greater than two, and the coefficient matrix is a linear combination coefficient matrix for the basis matrix, and transmits to the network at least one feedback comprising feeding back the basis matrix in a first periodicity and feeding back the coefficient matrix in a second periodicity. In one embodiment, the UE compresses the basis matrix and the coefficient matrix to a feedback basis matrix and a feedback coefficient matrix before transmitting.
