1. A method for determining an uplink transmission resource for a demodulation reference signal, comprising:
determining symbols occupied by a physical uplink control channel (PUCCH) in N consecutive time slots, N being a positive integer; and
determining a second symbol set of symbols occupied by the demodulation reference signal (DMRS) from the symbols occupied by the PUCCH, a number of the symbols in the second symbol set being less than a number of symbols in a first symbol set, and the first symbol set being determined according to a format of the PUCCH, a number of the symbols occupied by the PUCCH, and a distribution mode of the symbols occupied by the DMRS corresponding to the format of the PUCCH;
wherein the determining a second symbol set of symbols occupied by the DMRS from the symbols occupied by the PUCCH comprises:
determining a number of symbols in a second symbol subset of the second symbol set according to a number of symbols in a first symbol subset of the first symbol set and an adjustment factor, the first symbol subset and the second symbol subset corresponding to any one of the N consecutive time slots; and
determining positions of the symbols occupied by the DMRS in a time slot corresponding to the second symbol subset, according to the number of the symbols in the second symbol subset.
