Abstract
A communication method and apparatus in a high-frequency scenario are provided. 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, wherein 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.

A communication method in a high-frequency scenario, wherein the method is applied to a transmit-end device, and the method comprises:
- modulating, by the transmit-end device, 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 which is a terminal device, to generate M lower-order modulation signals, wherein M is an integer greater than or equal to 2, and S is equal to 1 or M;
- and
- sending, by the transmit-end device, the higher-order modulation signal formed by the M lower-order modulation signals, which are generated by the transmit-end device, through a line of sight (LOS) channel, wherein
- the M lower-order modulation signals are superposed based on the mapping rule to obtain the higher-order modulation signal to be received by the receive-end device.
A communication method in a high-frequency scenario, wherein the method is applied to a receive-end device which is a terminal device, and the method comprises:
- receiving, by the receive-end device, a higher-order modulation signal from a transmit-end device through a line of sight (LOS) channel, wherein the higher-order modulation signal is obtained by superposing, based on a mapping rule, M lower-order modulation signals generated by the transmit-end device by modulating S bitstreams according to the mapping rule, and M is an integer greater than or equal to 2, and S is equal to 1 or M;
- and
- performing, by the receive-end device, channel estimation by utilizing a demodulation reference signal (DMRS) port, and performing, by the receive-end device, post-equalization on the higher-order modulation signal based on a channel matrix obtained through estimation.
