Blind decoding of control information is used in some wireless multiple access systems such as LTE to achieve adaptive modulation and coding, as well as to address the multiple access problem on the control channel. Blind decoding incurs high computational complexity in mobile terminals. In this paper, we describe a scheme to reduce the computational complexity associated with the blind decoding. The main idea is to broadcast a "please-decode-blindly" message to all terminals that are eligible for scheduling, to instruct a subset of the terminals to perform the blind search. We propose two schemes to implement our idea and we investigate their performances via system simulations.
