Question: In the context of evolving NR (New Radio) duplex operation for unpaired spectrum, what is a key assumption regarding device capability during this study?
Option 1: Full duplex operation at both gNB (next-generation Node Base) and UE (User Equipment) sides
Option 2: Half duplex operation at the gNB side and full duplex at the UE side
Option 3: No restriction on duplex modes for either gNB or UE
Option 4: Half duplex operation at the UE side with duplex enhancement at the gNB side
Explanation: This answer reflects a nuanced understanding of balancing device limitations with potential network upgrades. It assumes half duplex at the UE side, focusing instead on gNB advancements for broader network efficiency and performance gains in NR TDD for unpaired spectrum, without overhauling existing UE capabilities.
