A precoding method, performed by a reconfigurable intelligent surface (RIS) array, includes determining a phase shift list corresponding to the RIS array, in which the phase shift list includes at least one row of phase shift sequence, the phase shift sequence includes a phase shift of each RIS array element in the RIS array, each row of phase shift sequence is configured to cause the RIS array to reflect an incident signal along a pair of reflection angles, and each row of phase shift sequence corresponds to one index value; acquiring a first index value from a user equipment (UE); determining a first phase shift sequence corresponding to the first index value from the phase shift list; and precoding the RIS array by configuring the phase shift of each RIS array element in the RIS array according to the first phase shift sequence.
