1. A method comprising:
receiving a master information block, wherein the master information block comprises first information indicating a first offset between a first location in frequency domain and a frequency domain reference location, and wherein the first location is associated with a first resource block index;
receiving a first demodulation reference signal based on the first resource block index, wherein the first demodulation reference signal is usable for demodulating a first downlink control channel, wherein a physical downlink control channel (PDCCH) resource associated with the first downlink control channel is configured by a physical broadcast channel (PBCH); and
receiving a second demodulation reference signal based on a second resource block index, wherein the second resource block index is associated with a second location in frequency domain, and the second demodulation reference signal is usable for demodulating a second downlink control channel other than the first downlink control channel; and wherein,
the first location is subcarrier 0 of a resource block, the resource block is a lowest numbered resource block of the PDCCH resource, and the frequency domain reference location is associated with a frequency domain location of a synchronization signal block.
