ABSTRACT:
A method for creating and maintaining semi-dynamic frequency hopping communities. Each community is a set of neighboring cells, such as wireless regional area networks (WRANs) according to IEEE 802.22, that follow a protocol defining coordinated frequency hopping operations, e.g., hopping is performed by community members according to a leader-defined hopping pattern rather than to channels selected in the prior operation period. Each community has one leader base station and one or more community member base stations. The leader determines membership, calculates hopping patterns for all members, and distributes the hopping information to the community members. Members provide their neighborhood and channel availability information, e.g., information about their sensing results and channel usage of neighboring WRANs. In exemplary communities, the community members are one-hop neighbors, each community member is configured to perform sensing concurrently with data transmissions, and the number of available channels is greater than the number of members.
