Most markets still rely on 5G Non-Standalone (NSA) as the main approach for commercial 5G. This setup allows operators to activate new radio (NR) capacity over an existing LTE core, […]
Addressing the uplink challenge of 5G NSA requires more than adding spectrum
Why Does 5G NR Support Two Uplink Waveforms? Understanding CP-OFDM and DFT-s-OFDM
The design question 3GPP actually faced LTE’s uplink was a single, non-negotiable decision: every PUSCH transmission uses SC-FDMA. 5G NR does not make that same trade-off unconditionally — it exposes […]
