Abstract
A signal sending method and a related apparatus are disclosed. In the signal sending method, an access network device obtains a channel information sample, determines M' frequency domain units in M frequency domain units in an (x+T)time unit based on the channel information sample, and sends one or more measurement pilots to a terminal in the M′ frequency domain units. The one or more measurement pilots are used to measure CSI, and the channel information sample includes channel information in an xtime unit to an (x+T−1)time unit, where M′<M. In the method, the access network device may determine the M′ frequency domain units in the M frequency domain units in the (x+T)time unit to send the one or more measurement pilots, to implement frequency-domain dimension reduction of the one or more measurement pilots.
