Embodiment 1
[0211] Embodiment 1: The horizontal-dimension reference signal and the vertical-dimension reference signal are configured in different subframes, and both adopt periodic configuration, and reuse the CSI-RS reference signal (that is, adopt the CSI-RS configuration information defined in the 3GPP standard, such as transmitting Period, subframe offset and other configuration information) to configure the horizontal dimension reference signal and the vertical dimension reference signal, the horizontal dimension reference signal and the vertical dimension reference signal can be mapped to the same or different frequency domain resources; assuming that the horizontal dimension reference signal and The vertical dimension reference signal is configured with the same transmission period P and different subframe offsets Δ H (the subframe offset of the horizontal dimension reference signal), Δ V (the subframe offset of the vertical dimension reference signal);
[0212] Then the n+Δ H T...
Embodiment 2
[0215]Embodiment 2: The horizontal-dimensional reference signal and the vertical-dimensional reference signal adopt periodic configuration, reuse the CSI-RS reference signal, and the horizontal-dimensional reference signal and the vertical-dimensional reference signal use the same or different frequency domain resources; assuming that the horizontal-dimensional reference signal and the vertical Dimensional reference signals are configured with different transmission periods and the same subframe offset, that is, the transmission period of the horizontal dimension reference signal is P H , and the sending period of the vertical dimension reference signal is P V , and the subframe offset is Δ, where P V =KP H , K is a positive integer;
[0216] Then configure the horizontal dimension reference signal in the n+Δth subframe, and the n+Pth subframe H The +Δ subframe configures the horizontal dimension reference signal, ..., the n+KP H +Δ subframes are configured with horizontal...
Embodiment 3
[0219] Embodiment 3: The horizontal dimension reference signal and the vertical dimension reference signal are configured in different subframes, and both adopt periodic configuration, reuse the CSI-RS reference signal, and the horizontal dimension reference signal and the vertical dimension reference signal use the same or different frequency domain resources ; Assume that the horizontal dimension reference signal and the vertical dimension reference signal are configured with different transmission periods and different subframe offsets, that is, the transmission period of the horizontal dimension reference signal is P H , and the transmission period of the vertical dimension reference signal is P V , and the subframe offset of the horizontal dimension reference signal is Δ H , and the subframe offset of the vertical dimension reference signal is Δ V , where P V =KP H , K is a positive integer;
[0220] Then the n+Δ H The horizontal dimension reference signal is configu...
