5G Sub-band Full Duplex: 3GPP Standardization Progress and Performance Analysis

Sub-band full duplex (SBFD) is a novel form of full duplexing that enables the simultaneous transmission of uplink (UL) and downlink (DL) signals on with non-overlapping frequency resources within the confines of the same unpaired time division duplexing (TDD) carrier. The latest advancements within the realm of the standard development of the third generation partnership project (3GPP) have driven this dynamic domain. An in-depth simulation and analysis are conducted to evaluate the performance metrics associated with SBFD, highlighting the substantial gains achieved in comparison to legacy TDD schemes, particularly in the context of UL transmissions. This comprehensive investigation and analysis underscore the potential advantages and implications of adopting SBFD in modern communication networks.
