  • Patent number: 10979187
    Abstract: This application provides a reference signal transmission method and an apparatus, to resolve a prior-art problem of relatively high overheads of resources occupied by transmitted reference signals in a communications system. The method includes: configuring, by a transmitting device, one reference signal group corresponding to one port in the first time symbol, and configuring one reference signal corresponding to the port in each of time symbols except the first time symbol. This reduces overheads of resources occupied by transmitted reference signals in the communications system and improves service data transmission efficiency while ensuring that a receiving device can obtain a channel parameter of the port.
