Methods and systems of signal transmission

Abstract

Life is a medium for developing methods of signal transmission and signal transmission systems. The method includes: receiving the first reference signal; receiving the demodulation reference signal (DMRS); determining the received parameters of the first signal based on the channel characteristics of the first reference signal and / or performing channel estimation for the first signal based on the channel characteristics of the first reference signal; In this system, each layer of the first signal is linked to N DMRS gates corresponding to the DMRS, and N DMRS gates are linked to a layer of the first signal that has a close isotopic relationship (Quasi Co-Location, QCL) with the N first reference signals.
