ABSTRACT:
A communications system may include a first wireless communications device communicating based upon a first wireless communications protocol, a second wireless communications device communicating based upon a second wireless communications protocol different from the first wireless communications protocol, and a wireless base station. The wireless base station may communicate with the first wireless communications device and the second wireless communications device based upon a frame structure. The frame structure may be defined by sub-carriers at respective different frequencies and symbols at respective different times. The frame structure may include a frame control header, a first frame portion for communicating with the first wireless communications device based upon the first wireless communications protocol, and a second frame portion for communicating with the second wireless communications device based upon the second wireless communications protocol.
