Abstract  Abstract

The invention mainly claims for reducing multiple OFDMA overlay embodiment of asynchronous interference and method of base station in the network. In some embodiments the lower layer base station configured to adjust OFDMA frame boundary so that frames transmitted by a higher layer of cyclic prefix at the lower layer in the base station is reached. the lower layer base station may also be configured to adjust the OFDMA frame boundary so that frames transmitted by the lower layer of network of cyclic prefix at a higher layer in the mobile station is reached. Therefore the frame from one layer can arrive within the cyclic prefix of another layer so as to reduce the asynchronous interference.

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.
