Example control channel resource indication methods, user equipment, and network devices are described. One example method includes sending a preamble signal sequence by a user equipment. The user equipment receives higher layer signaling corresponding to the preamble signal sequence. The higher layer signaling is indicated by downlink control information carried in a common search space. A time-frequency resource detected by the user equipment when determining a control channel includes the common search space and user equipment-dedicated search space. The user equipment determines frequency domain resource location information of the user equipment-dedicated search space based on the higher layer signaling. The frequency domain resource location information includes a quantity of frequency domain resource units occupied by the user equipment-dedicated search space in frequency domain and a location of the frequency domain resource unit.
