Abstract
This application discloses a wireless communication method, a wireless communications apparatus, and a wireless communications system. An example wireless communication method includes: receiving, by a terminal, indication information of uplink data transmission from a base station; determining, by the terminal, a base sequence configuration of a reference signal sequence corresponding to the modulation scheme of the uplink data transmission, and generating a dedicated demodulation reference signal based on the determined base sequence configuration of the reference signal sequence, where the modulation scheme of the uplink data transmission is one of a plurality of modulation schemes supported by the terminal, the plurality of modulation schemes include at least π/2 binary phase shift keying (BPSK), and a base sequence configuration of a reference signal sequence corresponding to the π/2 BPSK is different from a base sequence configuration of a reference signal sequence corresponding to another modulation scheme in the plurality of modulation schemes.
