摘要：A method for communications between neighboring wireless cells such as wireless regional area networks operating according to IEEE 802.22 specifications. The method involves scheduling inter-base station communications for over-the-air connections to allow neighboring base stations to communicate in environments where a single available channel is shared between the neighboring cells or where two or more channels used by two or more neighboring cells. In some embodiments, a bridge system, such as a bridge consumer premise equipment (CPE), positioned in an area of coverage overlap between two cells is used for inter-base station communications, and allocation and scheduling of bandwidth on the utilized channels is performed to provide interference free communications between the base stations. Existence announcements are provided in coexistence time slots and requests for bandwidth such as reserved and additional time slots are transmitted between the base stations using the coexistence time slots.
