Abstract
A method and system for providing multilingual wireless communications network are disclosed. The present invention discloses a mechanism of receiving and/or transmitting an OFDM data stream using IEEE 802.16-2004 standard and an OFDMA data stream using IEEE 802.16e standard. A timing division duplexing ('TDD') frame is configured to contain data that has different standards. At least a portion of OFDM data is allocated in a portion of the TDD frame while a portion of OFDMA data is allocated in another portion of the TDD frame. The TDD frame is subsequently transmitted to both OFDM subscriber stations and OFDMA subscriber stations.
