Simultaneous transmission and reception

I am interested to know if its possible to have Tx and Rx enabled simultaneously but in a TDD application.

The Tx channel will be briefly enabled to send a short burst of data, then it can be disabled to reduce noise coupling. So that we can process the response  immediately, we would like to keep the Rx on and monitor the data stream.

I accept that the Rx may briefly be saturated by leakage of the Tx signal through the duplexer. We would include protection to avoid damage.

We expect that we may need to use an external RF oscillator instead of internal VCO. Would this mitigate risk of VCO pulling?
