In NSA networking, which of the following modes is used to anchor 5G NR?
- A . OGSM
- B . WCDMA
- C . CDMA
- D . LTE
D
Explanation:
The non-standalone (NSA) mode of 5G NR refers to an option of 5G NR deployment that depends on the control plane of an existing 4G LTE network for control functions, while 5G NR is exclusively focused on the user plane.[7][8] This is reported to speed up 5G adoption, however some operators and vendors have criticized prioritizing the introduction of 5G NR NSA on the grounds that it could hinder the implementation of the standalone mode of the network

- C . The number of symbols in one slot is fixed to 14 regardless of the subcarrier spacing configuration.
- D . The symbols in a slot can be classified as downlink, uplink, or flexible.
