Is this possible both TDD-LTE and 5G NR work in the same band?

Hello Experts.

We are going to test Ericsson Spectrum Sharing (ESS) in B40 (2300-2400 MHz).
Our radio is RRU4418.
And solution is based on NSA.

I think ESS can’t work in TDD, it works only in FDD.

It is not defined in 3GPP only.
How spectrum will be shared in TDD?

In FDD it can be shared in time and frequency domain.

Ericsson ESS not possible in TDD.

Thanks all.

Just want to know is this possible or not.

In 3UK network also, DSS is implemented in 700Mhz and 2100Mhz FDD bands.

In FDD we also already trialed but in B40 ESS is not possible.

I echo that ESS do not work with TDD.
