TDD- Simulatneous transmission and reception of data in same frequency

Hello,

Is there any implementation done with respect to TDD. Currently we would
like to send data and receive in the same frequency. And it should
switch after every transmission like i send TX1 data RX1 receives, and
then send TX2 information RX2 receives…Could you please give me some
information on how can we proceed with implementation. and share some
examples if there are any

Thanks
Regards,
Asha
