Abstract: A compressed header format is used for messages transmitted in a wireless network. The compressed header includes a first address field and a frame control field including at least one bit specifying whether the first address is for an access point of the wireless communications network. The frame control field may further include at least one additional bit identifying whether the frame is being relayed by a relay node positioned between the access point and a wireless station. The frame control field may further include at least one further bit identifying whether AID is used for the first address field.

Abstract: A Dynamic Frequency Hopping Community (DFH Community) is formed from a plurality of Wireless Regional Area Network (WRAN) cells wherein each of the plurality of WRAN cells within the DFH Community is a one-hop neighbor of the leader cell. The leader cell sets and distributes a hopping pattern for use among the WRAN cells based on, in part, the number of usable channels and whether a WRAN cell is shared by two groups in the DFH Community.

Abstract: A first base station is associated with a first quiet period, and a second base station is associated with a second quiet period. The quiet periods are coordinated so that an amount of overlap between the quiet periods is acceptable. For example, the quiet periods could be coordinated so that no overlap exists between the quiet periods. During the first quiet period, the first base station and/or an associated device (such as a CPE served by the first base station) performs in-band sensing to detect wireless devices that use a first frequency or channel also used by the first base station. During the second quiet period, the first base station and/or a coordinate device (such as a CPE served by the first base station and assisting the second base station) performs out-band sensing to detect wireless devices that use a second frequency or channel also used by the second base station.

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.
