Super-frame structure for dynamic spectrum sharing in wireless networks

A coexistence communications method for use between wireless networks comprising:

• adopting a super-frame structure for use in a wireless network comprising a plurality of frames, wherein a first frame includes a super-frame preamble, a super-frame control header, a data portion, and a regular self-coexistence window, a plurality of intermediate frames include an OFDM symbol, a data portion, and a regular self-coexistence window, and a last frame includes an OFDM symbol, a data portion, and a joining self-coexistence window;
• using the self-coexistence windows to exchange inter-wireless network co-existence messages;
• and
• using a last reserved self-coexistence window to announce intra-wireless network negotiation decisions.

A coexistence communications method for use between wireless networks comprising:

• adopting a super-frame structure for use in a wireless network comprising a plurality of frames, wherein a first frame includes a super-frame preamble, a super-frame control header, a data portion, and a regular self-coexistence window, a plurality of intermediate frames include an OFDM symbol, a data portion, and a regular self-coexistence window, and a last frame includes an OFDM symbol, a data portion, and a joining self-coexistence window;
• discovering the self-coexistence reservation pattern on an out-of-band or in-band RF channel;
• identifying the reserved self-coexistence windows of source wireless networks on the out-of band or in-band RF channel from the discovered self-coexistence window pattern;
• and
• receiving coexistence beaconing protocol packets during the reserved self-coexistence windows of the source wireless networks on the out-of band RF channel.

A cross-channel coexistence communications method comprising:

• a wireless system on a first channel discovers an SCW reservation pattern on an in-band or out-of-band second channel using the SCI information or through constant monitoring of the second channel;
• the wireless system on the first channel identifies reserved SCWs of source wireless networks on the second channel from the discovered SCW pattern;
• and
• the wireless system on the first channel receives CBP PDU packets during the reserved SCWs of the source wireless networks on the second channel, or during a J-SCW of the second channel in which the source wireless network could also transmit CBP packets.
