1. A radio resource identification method, comprising:
obtaining orbital angular momentum (OAM) mode domain information, wherein the OAM mode domain information comprises a first OAM mode domain identifier, the first OAM mode domain identifier corresponds to a first transmission parameter of a vortex electromagnetic wave in a first OAM physical mode, or the first OAM mode domain identifier corresponds to a first ratio between the first transmission parameter and a reference value, and the reference value comprises a transmission parameter of a plane electromagnetic wave or a transmission parameter of a vortex electromagnetic wave in a specified OAM physical mode in a plurality of OAM physical modes; and any plurality of waveform symbols pass through a same vortex electromagnetic wave channel when being transmitted over resources identified by a same OAM mode domain; and
determining, based on the OAM mode domain information, a radio resource used for uplink transmission or downlink transmission.
