Abstract
The present disclosure provides a method and base station for Multiple User-Multiple Input Multiple Output (MU-MIMO) transmission in a wireless communication system. The base station re-allocates frequency resources of a DMRS port which are allocated to N first data flows to M second data flows, wherein M is greater than N, and N first data flows may be used by N first UEs or less than N first UEs. The base station designates a DMRS port for K second UEs involved in joint scheduling according to the re-allocation result of frequency resources of a DMRS port, and sends information of the designated DMRS port via a downlink control signaling to the K second UEs, where K is lower than M or equal to M.
