PROBLEM TO BE SOLVED: To provide an MU-MIMO (Multi-User Multiple Input Multiple Output) method and a base station, providing a demodulation reference signal (DMRS) port to integrally schedule a plurality of users.SOLUTION: The base station uses a demodulation reference signal port frequency-domain resource allocated for N first data streams, by reallocating into N second data streams 101. Here, M is greater than N. The N first data streams are used by first user terminals (UE) smaller than N in number. Based on the reallocation result of the DMRS port frequency-domain resource, the base station designates a DMRS port to K second UE participating in integral scheduling, to transmit the designated DMRS port information to the K second UE by downlink control signaling 102. Here, K is smaller than and including M.SELECTED DRAWING: Figure 1 |
