Research on Coverage and Networking Capability of 5G 40M FDD Bandwidth Enhancement Compared with 100M TDD
Abstract
3GPP Release 16 will freeze the 2.1GHz FDD NR enhanced 40M large bandwidth standard in July 2020. At present, a small number of terminals have experimental capability. In the 3.5GHz TDD NR network with 100M bandwidth, how to use 2.1GHz FDD NR has become a hot issue in the industry. This paper compares the coverage and capacity of 2.1GHz FDD NR and 3.5GHz TDD NR through link budget and theoretical calculation; compares the uplink and downlink coverage of the two systems through single station pull-out experiment; selects the existing network with 2.1GHz FDD NR and 3.5GHz TDD NR deployed at the same site as the experimental site, and analyzes the uplink and downlink networking capacity of the two systems through Driving Test (DT). Considering the influence of the number of transmitting antennas of existing terminals and the transmitting power of network equipment on the network planning, the network capacity of this experiment includes 2.1GHz 4T4R and 3.5G 64TR, the terminal capacity includes 2.1GHz 1T4R, 2.1GHz 2T4R and 3.5GHz 2T4R, and the power consumption of network equipment involves 2.1GHz: 4×40W and 4×60W; 3.5GHz: 160W and 200W. At present, there is no literature about the existing network experiment of multi-power consumption and multiterminal type, so this paper has important reference significance for operators to deploy 2.1GHz+3.5GHz network.
