Title: SENDING METHOD, RECEIVING METHOD AND APPARATUS FOR CHANNEL STATE INFORMATION REFERENCE SIGNAL
Abstract:
Provided by the present application are a sending method, receiving method and apparatus for a channel state information reference signal. The sending method for a channel state information reference signal comprises: a network device determining the number of antenna ports corresponding to a channel state information reference signal (CSI-RS) resource; dividing the antenna ports into at least two antenna port sets; determining a code division multiplexing (CDM) type corresponding to each antenna port set; sending CSI-RS resource configuration information to a terminal device, the CSI-RS resource configuration information being used to indicate a CSI-RS resource and a CDM type corresponding to the antenna ports in each antenna port set; and sending a CSI-RS of the antenna ports in the antenna port set according to the CDM type and the CSI-RS resource corresponding to each antenna port. Using the method and apparatus provided by the present application, it is possible to reduce the effect of configuring a uniform CDM type on a result of channel estimation or channel measurement performed by a CSI-RS.
