Abstract:
An evolved Node B (eNB) and method for coherent coordinated multipoint transmission with per CSI-RS feedback are generally described herein. The eNB may configure a first cooperating point and a second cooperating point to jointly transmit a multi-node channel-state information (CSI) reference signal (RS) (CSI-RS) in predetermined resource elements of a resource block. The eNB may receive CSI reports as feedback from user equipment (UE). The CSI reports may include a precoding matrix indicator (PMI) indicating relative phase information between the cooperating points based on the multi-node CSI-RS. The CSI reports for the multi-node CSI-RS may be restricted to a PMI of rank-1. The eNB may configure the cooperating points for a coherent joint transmission to the UE based at least on the relative phase information. The coherent joint transmission may also be jointly beamformed based on single-node PMIs.
