Abstract
Embodiments of an enhanced Node-B (eNB) configured to operate as a serving eNB in a coordinated multi-point (CoMP) communication network and method are generally described herein. The serving eNB precodes signals for transmission to user equipment (UE) using a precoding matrix that is selected based on a reference PMI for a beamformed transmission in accordance with a modulation and coding scheme (MCS) that is selected from a modified CQI. When operating in coordination mode, on more cooperating eNBs are configured to suppress interference to the UE using coordination PMIs during the resource block allocated for the beamformed transmission.
