%X <p>In order to maximize the spectrum utilization, the optimal transmission time of secondary user is derived according to primary user and secondary user's data transmission characteristics. An auto-adaptive spectrum sensing time allocation scheme based on partially observed Markov decision process (POMDP) was proposed. Execution of the best action based on the energy detection results and the belief state in the last decision slot was decided. Simulation claims that the proposed scheme can maximize spectrum utilization according to different collision probability constrain between primary users and secondary users.</p>
