A method for determining a precoding matrix of OAM and an apparatus thereof, which can be used in communication systems. The method comprises: on the basis of target antenna array units among antenna array units on a uniform circular array, independently sending respective reference signals to a second communication device (S201); receiving a precoding matrix indication index (PMI) of each target antenna array unit, which is determined on the basis of a reference signal and sent by the second communication device (S202); and according to the PMI of the target antenna array unit, determining a precoding matrix of each antenna array unit on the uniform circular array (S203). By means of the method for determining the precoding matrix of OAM and the apparatus thereof, beamforming can be separately performed on the antenna array units, thus suppressing the divergence angle of an OAM beam, and increasing the transmission distance of an OAM communication system.
