a first obtaining module configured to obtain a third frequency domain position for determining a downlink control channel resource set corresponding to the user equipment, based upon preset information of the first frequency domain position of a predefined first downlink control channel resource set, and/or based upon received first information, transmitted by a base station, including indication information of the second frequency domain position of the first downlink control channel resource set;
a second obtaining module configured to obtain a third time domain position for determining the downlink control channel resource set corresponding to the user equipment, based upon preset information of the first time domain position of the predefined first downlink control channel resource set, and/or based upon the received first information, transmitted by the base station, including indication information of the second time domain position of the first downlink control channel resource set; and
a first determining module configured to determine the downlink control channel resource set corresponding to the user equipment as a third downlink control channel resource set based upon the third frequency domain position and the third time domain position.
Optionally the first information is MIB information or SI; and
the first downlink control channel resource set is configured for transmitting a common downlink control channel, and/or the first downlink control channel resource set is configured for transmitting a UE-specific downlink control channel when the user equipment accesses a mobile communication network for the first time.
Optionally the first obtaining module includes:
