1. A method, comprising:
receiving downlink control information (DCI) from a network device, wherein the DCI schedules data, and indicates a modulation scheme of the data, the modulation scheme of the data is 16 quadrature amplitude modulation (16QAM) or quadrature phase shift keying (QPSK), and a modulation order corresponding to 16QAM is greater than 2, wherein the DCI includes a modulation and coding scheme (MCS) field having 4 bits, the 4 bits in the MCS field indicates MCS indication information; wherein when the 4 bits in the MCS field is equal to 15, the modulation scheme of the data is 16QAM; when the 4 bits in the MCS field is less than 15, the modulation scheme of the data is QPSK; and
receiving or sending the data based on the modulation scheme.
