Abstract
The present disclosure provides a communication method that a base station configures different CSI-RS ports with different periodicity based on UE requirement (e.g. mobility) to reduce CSI-RS overhead. And another method is to transmit partial CSI-RS ports in a cyclic shifted manner to further reduce the overhead. In addition, cyclic shifted transmission of split CSI-RS port groups are proposed to reduce the potential big difference of interference onto different CSI-RS port groups.
