A second obtaining module 102 is 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.
A first determining module 103 is 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.
For example, the preset information of the first frequency domain position of the predefined first downlink control channel resource set, and the preset information of the first time domain position of the predefined first downlink control channel resource set has been specified in a communication protocol, and shall be complied by both the base station and the user equipment, so the base station has determined a resource set to be occupied by the base station for transmitting a downlink control channel, for example, in the following three instances without any limitation thereto (only by way of an example), before the user determine determines the downlink control channel resource set corresponding to the user equipment.
