Channel measurements supporting coordinated multi-point operation

摘要

An aspect of this invention is a definition of a set of reused channel state information reference signal (CSI-RS) resources among transmission points, which can be lower power nodes, for intra- cell coordinated multi-point (CoMP) operation. Separate CSI-RS resources are defined for each transmission point for sporadic separate measurements to be made by user equipment. The sporadic measurements may be implemented with low additional overhead, and are used for generating potentially simplified CSI feedback to an evolved NodeB that enables adapting shared channel reuse and also potentially making related channel quality indicator (CQI) compensation.
