Title: METHOD FOR TRANSMITTING AND RECEIVING REFERENCE SIGNAL, NETWORK DEVICE AND TERMINAL DEVICE
Abstract:
Provided in the present application are a method for transmitting and receiving a reference signal, a network device and a terminal device, so as to increase the length of a pilot frequency sequence and to reduce correlation between the pilot frequency sequences. The method comprises: a network device determines a plurality of resource elements (REs) for carrying a first CSI-RS, the plurality of REs distributed across multiple resource units, wherein in each resource unit, the plurality of REs for carrying the first CSI-RS are located on multiple subcarriers of a same symbol, and at least two of the REs carrying the first CSI-RS have different values, and the values of the first CSI-RS are uploaded on the plurality of REs within each of the resource units by means of a first multiplexing code; and the network device sends to a terminal device the first CSI-RS by means of the plurality of REs.
