In another possible implementation, if a CRC of the control channel is scrambled by using a C-RNTI and/or a CS-RNTI, a start resource block of the data channel scheduled through the control channel is a start resource block in a bandwidth part (BWP), and the bandwidth part is a bandwidth part indicated by a first candidate control channel.
