Abstract

See full text

Channel quality indicator (CQI) and precoding feedback from a user equipment includes reporting of at least a first and a second precoding matrix indicator (PMI). First, second and third indices are determined based upon the first and the second PMI and third and fourth PMI and are employed to select the precoding matrix. The selected precoding matrix includes a first column comprising a first row partition and a second row partition, where the first row partition is a Kronecker product of at least first and second precoding vectors and the second row partition is a Kronecker product of a first term and a second term. The first term is a product of a co-phasing factor and the first precoding vector and the second term is the second precoding vector. The first precoding vector is selected from a first codebook and the second precoding vector is selected from a second codebook.
