A method for mapping a control channel, a method for detecting the control channel and devices thereof are disclosed. The method for mapping the control channel includes: for the same aggregation level, according to a signaling length of the control channel corresponding to a component carrier, a corresponding searching space is determined for at least two control channels with the same signaling length, so as to enable at least two control channels with the same signaling length to use the same searching space (11), at least two control channels with the same signaling length are mapped to the determined corresponding searching space (12); and/or, corresponding searching spaces are determined for at least two control channels with the different signaling length, respectively, so as to enable at least two control channels with the different signaling length in at least one time transmission unit to use different searching spaces, at least two control channels with the different signaling length are mapped to the determined corresponding searching spaces, respectively. It not only can reduce the conflict of the control channel, but also can reduce the number of the blind detection of the control channel by using the method for mapping a control channel, the method for detecting the control channel and the devices thereof.
