Abstract
The invention relates to systems and methods for spectrum sharing and communication among several wireless communication networks with overlapping service areas (or cells); especially to Wireless Regional Area Networks (WRANs). Particular embodiments of the invention disclose using a conference channel to communicate between base stations. Other embodiments use slotted coexistence windows within frames to transmit and receive information, including for reserving transmission times within subsequent frames.
Claims18
A multi-channel inter-base station (BS) communication system, comprising:
- a plurality of wireless communication networks with overlapping service areas;
- and
- a plurality of wireless communication channels that can be used by the wireless communication networks;
- wherein each wireless communication network comprises a BS and a plurality of consumer premise equipment (CPE) transceivers;
- wherein communication both within and between the wireless communication networks uses synchronized frames;
- wherein one of the wireless communication channels is selected as a conference channel on which the base stations exchange information, including coexistence information;
- and
- wherein at the end of each frame is a slotted co-existence window comprising a hosting slot known to other wireless communication networks.
A method of communicating among a plurality of wireless communication networks, each comprising a base station (BS) and a plurality of consumer premise equipment (CPE) transceivers, having overlapping service areas and a plurality of wireless communication channels available for use, the method comprising:
- using synchronized frames to communicate both within and between wireless communication networks;
- selecting and using one of the wireless communication channels as a conference channel on which the base stations exchange information, including coexistence information;
- and
- including a slotted coexistence window at the end of each frame, wherein the slotted coexistence window comprises a hosting slot known to the other wireless communication networks.
A multi-channel inter-base station (BS) communication system, comprising:
- a plurality of wireless communication networks with overlapping service areas;
- and
- a plurality of wireless communication channels that can be used by the wireless communication networks;
- wherein each wireless communication network comprises a BS and a plurality of consumer premise equipment (CPE) transceivers;
- wherein communication both within and between the wireless communication networks uses synchronized frames;
- wherein one of the wireless communication channels is selected as a conference channel on which the base stations exchange information, including coexistence information;
- and
- wherein at the end of each frame is a slotted co-existence window, wherein the slotted co-existence window comprises a hosting slot for transmitting a hosting message and two discussion slots for transmitting and receiving data, and
- wherein the hosting message is in a first hosting slot position in a first data frame and the hosting message is in a second hosting slot position in a second subsequent data frame and the second hosting slot position is incremented from the first hosting slot position by a modulo factor to the second hosting slot position.
