Abstract: This invention is a technique for coordinate multi-point wireless transmission between a plurality of geographically separated transmission points (TP) and at least one user equipment (UE). For coordinated multi-point communication (CoMP), UE measures the downlink wireless propagation channel corresponding to multiple geographically separated transmission points.

Each CSI report is defined as a “CSI-process”, where a CSI-process with a lower CSI-process-index has a higher priority. Multiple CSI-processes can be reported periodically. Each periodic CSI feedback comprises a single CSI-process.
