    摘要： The subject matter disclosed herein provides methods and apparatus for closed loop operation of a wireless system implementing multiple input multiple output (MIMO). In one aspect, there is provided a method. The method may include receiving a payload including channel estimation information. Moreover, one or more bits of the payload may be inserted into a subset of the tiles of a slot. The slot including the subset of the tiles carrying the one or more bits of the payload may be provided as part of a closed loop MIMO-based system. Related systems, apparatus, methods, and/or articles are also described.

    摘要： 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.

    摘要： In an orthogonal frequency division multiplex (OFDM) communication network, a node transmits an echo profile probe to other nodes in the network. The echo profile probe is a message that allows characterization of the unique echo profile through the communication channel between each node pair. The echo profile is used to calculate the cyclic prefix length needed for optimum communication from one node to the other.
