Abstract
A user equipment (UE) receives a first channel state information reference signal (CSI-RS) on a first set of beams and receives a second CSI-RS on a second set of beams. The apparatus determines a channel quality indicator (CQI), a rank indicator (RI), and a precoding matrix indicator (PMI) based on the first CSI-RS. The apparatus reports the CQI and RI using an uplink control channel and indicates the PMI using a precoded SRS transmission. The precoded SRS transmission may be precoded based on a dissimilarity between the first CSI-RS and the second CSI-RS. The first CSI-RS may include a defined precoder, and the second CSI-RS may include a precoder based on an uplink channel estimate of a non-precoded SRS from the UE.
