Study on evolution of NR duplex operation
The present document captures the results and findings from the study item "Study on Evolution of NR Duplex Operation " [2]. The purpose of this TR is to document the follows for evolution of NR duplex operation:
- applicable and relevant deployment scenarios.
- evaluation methodology and assumptions.
- possible schemes/enhancements, feasibility and performance evaluation results of subband non-overlapping full duplex and dynamic/flexible TDD.
- summary of the regulatory aspects that have to be considered for deploying the identified duplex enhancements in TDD unpaired spectrum.
This activity involves the Radio Access work area of the 3GPP studies and has potential impacts both on the Mobile Equipment and Access Network of the 3GPP systems.
