Claim 3:
4. A method, comprising:
determining a demodulation reference signal sequence corresponding to position offset information, wherein the position offset information comprises a first position and a first offset, wherein the first position is a quantity of subcarriers by which a center subcarrier of a reference point of a first broadcast channel is offset from a center subcarrier of a reference point of a second broadcast channel carrying a master information block (MIB), and wherein the first offset comprises a quantity of subcarriers by which a smallest subcarrier of a control channel resource set is offset from the smallest subcarrier in a bandwidth part of the second broadcast channel, and a quantity of subcarriers by which the smallest subcarrier in the bandwidth part of the second broadcast channel is offset from the center subcarrier of a resource on which the reference point of the second broadcast channel; and
mapping the demodulation reference signal sequence to at least one resource element in the control channel resource set, wherein the at least one resource element is used for transmitting a demodulation reference signal corresponding to the demodulation reference signal sequence.
