摘要：
According to the spectrum partitioning decisions of Wi-Fi and LTE respectively depended on global channel state infor-mation (CSI) and local CSI, an online two-timescale iteration algorithm was developed. The Wi-Fi spectrum was partitioned at the large timescale according to the global CSI whereas the LTE spectrum was partitioned according to the fast-changing local CSI. Then, the adaptive compensation mechanism was designed for improving the tracking performance of the two-timescale algorithm. Moreover, the sufficient condition was derived for the two-timescale algorithm tracking the moving equilibrium point without errors. Finally, the simulation results show that the proposed two-timescale algorithm achieves excellent system performance at very low overhead. © 2021, Editorial Board of Journal on Communications.
