Research on 2.1GHz 4/5G Cooperative Networking Scheme and Interference
3GPP release 16 had frozen the 2.1GHz FDD NR enhanced 40m bandwidth standard in July 2020. China Telecom and China Unicom will jointly use this frequency band to balance the growth of 4G capacity and realize the wide coverage of 5G network at the same time. 2.1GHz has the following networking options: 20M LTE + 20M LTE, 20M DSS + 20M DSS, 20M LTE + 20M NR, 40M DSS and 40M NR. In order to give consideration to the two communication systems, various networking schemes will also introduce interference between different systems. This paper analyzes various networking technical schemes of 2.1GHz, gives theoretical evaluation of performance interference, and verifies the impact of interference on performance in typical 4/5G cooperative networking scenario through driving test of field trial. At present, there is no literature on the performance analysis and experimental verification of various 4/5G cooperative networking schemes under 2.1GHz 40M large bandwidth. This paper has important reference significance for operators to deploy 4/5G cooperative network to realize the smooth evolution from 4G to 5G.
