METHOD AND APPARATUS FOR CHANNEL MEASUREMENTS FOR COORDINATED MULTIPOINT TRANSMISSION

摘要

The present invention relates to a method for configuring reference signals and measurement sets to support coordinated multipoint transmission with distributed antennas. A first set of reference signal patterns is used for measuring and reporting received signal power from different transmission points, and a second set of reference signal patterns is used for measuring and reporting channel state information from different transmission points. The method allows to minimize power consumption and feedback overhead, while still being flexible in the configuration and re-configuration of the measurement sets.
