<p>A method and device for measuring channel state information and for transmitting reference signals. The method comprises: receiving reference signal configuration information transmitted by a transmitter device and reference signals of an N-number of reference signal ports configured, and measuring channel state information (CSI) on the basis of the reference signals of the N-number of reference signal ports configured, where N ≥ 6, the N-number of reference signal ports consist of an M-set of reference signal ports, and M ≥ 1. The measurement of the CSI on the basis of the reference signals of the N-number of reference signal ports configured comprises: respectively measuring CSI for the reference signal of each port among the M-sets of reference signal ports, acquiring an M-number of first precoding matrices, that is, Wi, where i = 1, 2,…, M; acquiring, on the basis of the first precoding matrices, a second precoding matrix W, where W = W1 ⊗ W2 ⊗…⊗ WM; and, acquiring a channel quality indicator (CQI) on the basis of the second precoding matrix. The solution implements measurement of CSI.</p> |
