Hello 5G Experts. I’ve found a nice article, and I think you may like…
When an airplane moves through the air, drag is an inevitable obstacle that grows as speeds increase. Similarly, radio signals travel through a challenging environment of distortions and self-interference that increase exponentially with network density and complexity.
Self-interference occurs when a transmitter jams its own receiver. Over the last century, two different methods for getting around self-interference have seen wide adoption - Frequency Division Duplex (FDD) and Time Division Duplex (TDD). In FDD, different frequency channels separated by a substantial distance in frequency are allocated to transmit and receive so that RF filters can be used to reduce self-interference. In TDD, transmit and receive happen in non-overlapping time slots across a time synchronized network so that only the transmitter OR the receiver is active at any given time. In both methods, there is substantial wastage of valuable spectrum resources.
