In full duplex applications, it's very likely that you're interfering
with yourself. Some sort of filter may be required on the receiver to
attenuate the transmitter signal.
What kind of filter depends on the size of the duplex gap (the frequency
span between transmit and receive). If the gap is large, then you can
just use a high or low pass filter. For example:

Hi Muller/All,
Just a quick question.
During our 5G-NR integration with USRP B210, we observe very high noise
power at receiver.
Is it expected behavior ?
PBCH rsrp: -13.775554 dBm, SNR: -12.942591 dB, NOISE_POWER: -0.832963 dBm,
rssi: 1.643662dBm.
Applied gain in USRP:
Tx Gain: 45
Rx Gain: 45
Transmit power:- 0dBm.
Regards,
Prasad.
