METHOD AND APPARATUS FOR SYNCHRONIZATION IN COGNITIVE RADIO NETWORKS

摘要

to share a frequency band in the first and second flexible wireless system 200 including a wireless network, devices of self- coexistence method for enabling (300 ) is provided. The method comprises the steps of finding a second device operable in a second wireless network which overlaps with the first wireless network (S310); The second device is found in the first step to report the first device capable of operating in a wireless network (S320); Determining a need for adjustment between the second beacon period of the first beacon period of the first device and the second device (S330); And if necessary, adjusted , and a first beacon period start time of the first device (BPST) to the step (S370) for adjusting according to claim 2 BPST of the second device . ;
