Embodiments of the present application provide a wireless communication method, a terminal device, and a network device. A codebook supporting more than four antenna ports is designed. The wireless communication method comprises: the terminal device obtains first information, the first information being used for determining a precoding matrix for uplink information transmission; the terminal device pre-codes uplink information by using the precoding matrix; and the terminal device sends pre-coded uplink information, the first information being determined according to at least one of codebook subset configuration information, antenna port number information, maximum number of transmission layers of uplink information, waveform used by uplink transmission, and first indication information, the codebook subset configuration information being used for indicating a codebook subset to which the precoding matrix belongs, the antenna port number information being used for indicating the number of antenna ports used by the terminal device to send the uplink information, the number of antenna ports being greater than 4, the number of antenna ports being a multiple of 2, and the first indication information being used for indicating a precoding matrix index.
