    Abstract: Methods and apparatus are described for mitigating intercell interference in wireless communication systems utilizing substantially the same operating frequency band across multiple neighboring coverage areas. The operating frequency band may be shared across multiple neighboring or otherwise adjacent cells, such as in a frequency reuse one configuration. The wireless communication system can synchronize one or more resource allocation regions or zones across the multiple base stations, and can coordinate a permutation type within each resource allocation zone. The base stations can coordinate a pilot configuration in each of a plurality of coordinated resource allocation regions. Subscriber stations can be assigned resources in a coordinated resource allocation region based on interference levels. A subscriber station can determine a channel estimate for each of multiple base stations in the coordinated resource allocation region to mitigate interference.

    Abstract: Methods and apparatus are described to facilitate co-channel co-existence in a wireless communication environment. First information and second information related to a shared channel may be transmitted. The first information may be transmitted across a plurality of subcarriers over a first symbol set of a subframe and the second information may be transmitted within a subset of the plurality of subcarriers over a second symbol set of the subframe. The second information may include channel-sharing information regarding the wireless communication environment. The channel-sharing information may reduce intercell interference with at least one other base station.

    Abstract: A method of wireless communication including a base station transmitting a preamble including information indicating a sector identifier and an antenna port value. The base station further transmits a pilot sequence, wherein the pilot sequence and the location of the pilot sequence are based on the sector identifier and on the antenna port value. A base station configured to perform the method is also disclosed. A corresponding subscriber station configured to receive the preamble and pilot sequence is also disclosed, as well as a subscriber station method.
