摘　　要：通过链路预算与理论计算对比了2.1 GHz FDD NR与3.5 GHz TDD NR 2种NR网络制式的覆盖能力与容量;通过单站拉远实验对比了2种制式上下行的覆盖能力;通过DT测试对比分析了2种制式同站址部署时,不同终端发射天线数和不同发射功率情况下的上下行组网能力,对运营商协同部署2.1 GHz+3.5 GHz网络有重要参考意义。It compares the coverage and capacity of 2.1 GHz FDD NR and 3.5GHz TDD NR through link budget and theoretical calculation,and compares the uplink and downlink coverage of the two systems through single station pull-out experiment.Through DT test,the uplink and downlink networking capabilities of the two systems under different terminal transmit antennas and different transmit power are compared and analyzed,which has important reference significance for operators to deploy 2.1 GHz+3.5 GHz network.
