A method for reusing control channel resources in a wireless system includes selecting a subset of control channel resources from a specified set of control channel resources in a search space of the wireless system. The subset is smaller than the set. In addition, the method includes transmitting a first control channel using only the subset of control channel resources. Further, the method includes selecting at least one of the control channel resources not transmitted in the first control channel. Furthermore, the method includes transmitting a different control channel using at least one of the control channel resources specified for but not scheduled in the first control channel.
