Multi-cell cooperative RS in CoMP
The DL RS, including UE-specific demodulation RS (DM-RS) and cell-specific measurement RS (CSI-RS), has been discussed extensively in the past RAN1 meetings. The way forward on high-level design principles of DM-RS and CSI-RS were proposed by many companies and agreed on previous two meetings [1][2]. Based on the agreements therein, this paper presents our further considerations on CSI-RS design, with special attentions and considerations on improving multi-point channel measurement quality, which can facilitate the channel measurements in DL CoMP transmissions.
