Self-coexistence of devices in a flexible wireless system including two or more wireless networks that share a frequency band

A network device (510) operable in self-coexistence with network devices in a flexible wireless system (200) that includes first and second wireless networks sharing a frequency band, the network device comprising:

• a detection unit (510) for discovering a second device operable in the second wireless network that overlaps with the first wireless network;
• an information element generator (520) for reporting the discovered second device to other network devices operable in the first wireless network;
• a decision unit (530) for determining if an adjustment is needed between a beacon period of the network device and a second beacon period of the second device;
• and
• a beacon period start time (BPST) adjustment unit (540) for adjusting a BPST of the network device with a second BPST of the second device, if the adjustment is needed.
