1. A method, comprising:
configuring at least two virtual antenna mapping matrices, wherein each of the at least two virtual antenna mapping matrices indicates a respective mapping relationship between four antenna ports and N physical channels, and N is an integer greater than 4, and wherein different ones of the at least two virtual antennal mapping matrices indicate a different mapping of the four antenna ports to the N physical channels;
obtaining channel state information of a target terminal device in a target cell;
selecting, based on the channel state information, a target virtual antenna mapping matrix from the at least two virtual antenna mapping matrices, wherein the target virtual antenna mapping matrix indicates a first mapping relationship between the four antenna ports and the N physical channels; and
performing wireless communication with the target terminal device based on the target virtual antenna mapping matrix.
