description The invention discloses an NOMA wireless transmission method based on a reflection and transmission metasurface, and the method comprises the steps: firstly setting an initial value of a reflection and transmission phase shift matrix of the reflection and transmission metasurface as a random diagonal matrix, and dividing a terminal into a reflection terminal and a transmission terminal according to different transmission modes; then respectively designing sending beam matrixes of the reflection terminal and the transmission terminal, and obtaining an optimal power distribution factor; designing an optimal reflection and transmission phase shift matrix of the reflection and transmission metasurface by using the obtained result, and carrying out iterative optimization again according to the optimized phase shift matrix until the traversal and rate convergence of the system; and obtaining a global optimal solution of a reflection and transmission phase shift matrix, a sending beam matrix and a power distribution
