Why 5G Stand-alone offers better UL Coverage and performance compared with 5G NSA?

In 5G NSA: in 5G non-standalone, the UE utilizes one TX branch for each leg, one TX branch for 4G, and one TX branch for 5G.

Accordingly, Due to dual connectivity, UE will lose 3dB Tx power and 1 Tx transmission channel in NSA architecture.

In 5G SA: 5G SA Fully utilizes 2 UE TX for 5G, which will add up the power when using the two TX branches; accordingly, it offers better coverage by 3dB and better UL speed due to fully utilizing 2 UE TX for SA.

That’s for sharing @Mohamedeladawi!!

Just wondering, is there any mention of this in the 3GPP specs? If so, where can I check it out? Or any other source about this…


This information shared based on pervious experience but still you can find related information for the same subject in section 7.6, “Dual connectivity” in 3GPP TS 38.213 V16
