FD Challenges in the Context of Modern Base Station Transceivers

The new 6G communication standard is in favor of full-duplex (FD) or sub-band FD (SBFD) to meet latency and coverage requirements or allow even new sensing functionalities. Practical challenges for modern base stations are addressed to balance FD/SBFD expectations, practical design options and costs for different frequency bands and deployments. Latest isolation results of a digital and analogue FIR cancellation approach are highlighted.
