Abstract: This application provides a communication method and apparatus in a high-frequency scenario. The method includes: A transmit-end device may modulate S bitstreams according to a mapping rule corresponding to a first modulation scheme for a higher-order modulation signal to be received by a receive-end device, to generate M lower-order modulation signals, where S is equal to 1 or M, and M is an integer greater than or equal to 2; and then send the M lower-order modulation signals through a line of sight LOS channel, so that a modulation order of a signal transmitted by a transmit end can be reduced.
