In this paper, a two-way cooperative spectrum access strategy is proposed to optimize the performance of secondary user (SU), which is based on joint allocation of time and bandwidth. In the strategy, the unit transmission time is divided into three time slots. Primary users (PU) communicate with each other in the first two time slots with the help of secondary user. Thus the secondary user can access the spectrum to transmit its own signal in the third time slot. Besides, through joint optimization of time and bandwidth, the transmission rate of secondary user can reach the maximum when the target rate of primary user is guaranteed.
