I want to implement OFDMA Network on OMNET++ and for that i need to generate OFDM frames from Transmitter. How should i generate OFDM frames containing OFDM symbols on MAC level as OFDM symbol require operations (i.e QAM and IFFT ) which are most associated with the Physical Layer.

Thanks alot for the links and references, its quite helpful to my related work
Dear Pir,
The OFDM symbols are generated in the physical layer under the control of the mac layer which is responsible for building frames of transmitted signals. In fact the two layers can be merged to build one layer that is implemented using hardware or firm ware. So, you can generate the ofdm symbols also in the mac layer and consider that you merged the two layers in one layer. The division into layers is a matter of dividing functions and responsibility of the communication network.
Best wishes
