| Abstract | A method for operating user equipment (UE) in an advanced wireless communication network. The method comprises receiving, from an eNodeB (eNB), downlink signals indicating precoder codebook parameters that include a first number of antenna ports (N1) for a first dimension, a second number of antenna ports (N2) for a second dimension, and a codebook configuration, swapping precoder matrix indicator (PMI) expressions based on the N1 and N2, and the codebook configuration in order to derive a first PMI pair (i1,1, i1,2), and a second PMI (i2) using a single precoder codebook, and transmitting, to the eNB, channel state information (CSI) including the first PMI pair and the second PMI. |
