Subband full duplex (SBFD) increases uplink duty cycles, reduces uplink and downlink communication latency and improves user-perceived throughput and coverage. Looking ahead to 6G, Giga-MIMO pushes this evolution further by incorporating thousands of antennas alongside advanced signal processing techniques. Subband Full Duplex (SBFD) constrains full duplex to distinct downlink and uplink subbands within a single time division duplex (TDD) carrier. SBFD base stations avoid CLI with adjacent TDD operators by introducing uplink subbands to downlink time slots. Rely on field-proven techniquesOver-the-air measurements at 3.5 GHz with two commercial devices showed that advanced mitigation restored uplink throughput otherwise lost to self-interference.
