  • Base station and method for reducing asynchronous interference in a multi-tier OFDMA overlay network
    Patent number: 8630229
    Abstract: Embodiments of a base station and method for reducing asynchronous interference in a multi-tier OFDMA overlay network are generally described herein. In some embodiments, a lower-tier base station is configured to adjust OFDMA frame boundaries to cause frames communicated by a higher-tier to arrive within a cyclic prefix at the lower-tier base station. The lower-tier base station may also be configured to adjust OFDMA frame boundaries to cause frames communicated by a lower-tier of the network to arrive within a cyclic prefix at a higher-tier mobile station. Accordingly, frames from one tier may arrive within the cyclic prefix of another thereby reducing asynchronous interference.
