1. A method performed by a terminal device, the method comprising:
generating a demodulation reference signal (DMRS) sequence based on a sequence group,
wherein the sequence group is determined by a first parameter,
wherein the first parameter equals a second parameter in a case where a first condition is satisfied,
wherein the first condition comprises:
the second parameter is configured by a higher layer parameter nPUSCH-Identity, a physical uplink shared channel (PUSCH) is neither scheduled by random access response (RAR) uplink (UL) grant nor scheduled by downlink control information (DCI) format 0_0 with cyclic redundancy check (CRC) scrambled by temporary cell-radio network temporary identifier (TC-RNTI), and a first higher layer parameter related to transform precoding of the DMRS sequence is not configured;
wherein the first parameter equals a third parameter regardless of the second parameter in a case where a second condition is satisfied,
wherein the second condition comprises:
the first higher layer parameter is configured, π/2-BPSK modulation is used for the PUSCH, and the PUSCH transmission is not a msg3 transmission, and
wherein the first parameter equals a fourth parameter in a case where neither the first condition nor the second condition is satisfied, the fourth parameter being related to a cell identity; and
transmitting the DMRS sequence to a network device.
