Claim 0:
1. A method, comprising:
obtaining 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;
obtaining a demodulation reference signal sequence based on the position offset information; and
demodulating, by using the demodulation reference signal sequence, a control channel in the control channel resource set, to obtain downlink control information.
