Abstract: A communication method and apparatus are provided. The method includes: A terminal device receives a first downlink reference signal from a first network device, and the terminal device receives a second downlink reference signal from a second network device. The terminal device determines channel state information. The channel state information is determined based on a ratio of a first channel estimation value to a second channel estimation value. The first channel estimation value is determined based on the first downlink reference signal, and the second channel estimation value is determined based on the second downlink reference signal. The terminal device sends the channel state information.
