this paper researches on the uplink interference risk of 5G NR at both 2.6 GHz and 4.9 GHz frequency range. Then based on the outdoor interference test
the relationship between 5G NR network performance and interference level is clarified and the proposed interference threshold of 5G NR and LTE anchor are given. This paper proposes an interference analysis method adapting to both SA and NSA
which could guide the interference analysis and optimization of 5G NR.
