Abstract
A method and apparatus for mapping and detecting control channel are provided. The method for mapping a control channel includes: for the same aggregation level according to a signaling length of a control channel corresponding to a component carrier determining a corresponding search space for at least two control channels that have the same signaling length so as to enable the at least two control channels that have the same signaling length to use the same search space and mapping the at least two control channels that have the same signaling length to the determined corresponding search space. Therefore conflicts between the control channels are reduced and the number of times of blind detection of the control channels is also reduced.
