Performance evaluation on key techniques for 5G enhanced mobile broadband by Longchang ZHU, Xiaodong JI, Xinran ZHANG, Quxin LI

“…The 5G eMBB scenario puts high requirements on performance such as spectrum efficiency and system capacity.It was proposed to introduce technologies such as massive MIMO and millimeter-wave communication,and combine heterogeneous networks to improve system performance,because traditional technologies cannot bring about corresponding performance improvement.At the same time,there are few simulation evaluation results for the key technologies of the eMBB scenario,and the performance advantages of each technology cannot be explained from the perspective of simulation.The performance of massive MIMO with different antenna numbers by building a system-level simulation platform were evaluated,and the impact of the density and bias of micro BS in the mmWave frequency to the performance based on the results in the heterogeneous networks was summarized.It has great refer-ence value for parameter configuration and network construction of 5G network.…”

An approach of LTE measurement report based 2.1 GHz and 3.5 GHz 5G SA coverage evaluation by Jianxian LU, Jiqiu HUANG, Mingxing HU, Henghua LIN

“…2.1 GHz refarming is a key issue for the evolution of 5G network.Limitations of network simulation were analyzed.Since most of 5G sites were co-sited with LTE and adopted the same or similar engineering parameters, an approach of 2.1 GHz and 3.5 GHz 5G SA network coverage evaluation was proposed.A co-site coverage differential model between 2.1 GHz and 3.5 GHz 5G SA was given and its accuracy was verified by field trial.Then the coverage of two frequencies were predicted based on LTE MR, the differential model and the uplink rate curve relative to link loss.The evaluation instance indicates only 1.3～5.2 pp coverage gain is achieved at uplink rate between 1 Mbit/s and 10 Mbit/s by refarming 2.1 GHz within 20 MHz bandwidth, because of the 10 dB margin of LTE coverage.…”
