Title:
SIGNAL TRANSMISSION METHOD AND DEVICE, REFLECTOR, AND RECEIVER
Document Type and Number:
WIPO Patent Application WO/2021/097597
Kind Code:
A1
Abstract:
The present application provides a signal transmission method and device, a reflector and a receiver. Said method may comprise: a reflector receiving W excitation signals, wherein W exciters can be used to carry data and reference signals reflected by the reflector; and the reflector reflecting data and L reference signals to a receiver, the L reference signals being respectively carried in L excitation signals among the W excitation signals, W and L both being integers greater than 1 or equal to 1, and L being less than or equal to W. On the basis of the present application, channel estimation and data demodulation performance of a receiving end can be improved.
