To support dynamic traffic-asymmetry property in future wireless communication systems, the authors propose a hybrid-TDD scheme, combination of static-TDD and dynamic-TDD. By using adaptive power control, inner/outer scheduling and hybrid-link for guaranteeing safe downlink/uplink time-slots, they can effectively solve the interference problems of the dynamic-TDD scheme. Especially, an adaptive downlink power control strategy in hybrid-link region can efficiently reduce severe BSBS interference compared with other conventional schemes. Through numerical analysis and simulation results, they prove that their proposed scheme has the best performance compared with other conventional schemes in view of spectral efficiency and downlink/uplink outage probability.
