Multi-channel inter base-station communication
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.
1. A wireless communication network comprising a base station (BS) and a plurality of consumer premise equipment (CPE) transceivers;
wherein communication within the wireless communication network uses synchronized frames;
wherein a wireless communication channel is selected as a conference channel;
wherein at the end of each frame is a slotted co-existence window comprising a hosting slot;
wherein the slotted co-existence window comprises the 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.
2. A method of communicating between a base station (BS) and a plurality of consumer premise equipment (CPE) transceivers, the method comprising:
using synchronized frames to communicate between the BS and the CPE transceivers;
selecting and using a wireless communication channel as a conference channel; and
including a slotted coexistence window at the end of each frame, wherein the slotted coexistence window comprises a hosting slot,
wherein the slotted co-existence window comprises 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.
3. A communication system, comprising:
a plurality of WRAN cells;
wherein communication between the WRAN cells uses synchronized frames;
wherein a wireless communication channel is selected as a conference channel; 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.
4. The system of claim 3 , further comprising a co-existence beacon (CB) frame comprising a plurality of co-existence window slots over at least two frames and including a hosting message, wherein the hosting message includes mapping and payload information for the CB frame.
5. The system of claim 4 , wherein the CB frame is a super-frame.
