Abstract: The present disclosure relates to precoding matrix determining methods, devices, and systems. In one example method, a receive end device obtains channel state information (CSI) of a first channel and information about P antenna port groups of a transmit end device. The receive end device determines V orbital angular momentum (OAM) mode groups based on the CSI of the first channel and first OAM modes, determines a first precoding matrix based on the P antenna port groups of the transmit end device and the V OAM mode groups, and sends, to the transmit end device, first indication information indicating the first precoding matrix. The transmit end device receives the first indication information, and determines the first precoding matrix based on the first indication information.

Abstract: An antenna includes: a dielectric plate provided with a first surface and a second surface; a ground plane located on the first surface; and an antenna unit. A size of the antenna unit is a preset length, the antenna unit includes at least three antenna elements in a ring arrangement, and each antenna element includes a first patch, a second patch, and a third patch that are located on the second surface, and three conductive portions that penetrate through the first surface and the second surface. A first conductive portion is electrically connected between a feeding portion and the first patch to form a monopole, a second conductive portion is electrically connected between the ground plane and the second patch to form a first parasitic body, a third conductive portion is electrically connected between the ground plane and the third patch to form a second parasitic body, and the first parasitic body and the second parasitic body are located on both sides of the monopole and are configured to isolate adjacent antenna elements in the ring arrangement.
