Abstract
With the advancement of 5G network construction,the number of scenarios where 5G networks using the 2.6 GHz and 700 MHz frequency bands share physical sites is increasing.TDD 2.6 GHz with a bandwidth of 100 Mbit/s has the advantages of large bandwidth and high speed.However,compared with FDD 700 MHz,TDD 2.6 GHz has problems of insufficient in-depth coverage and limited uplink coverage.The FDD 700 MHz with a bandwidth of 30 Mbit/s has a low propagation loss and a strong penetration capability,and it is more suitable for deep coverage and uplink coverage.But the speed at near-end area is much lower than that of the 2.6 GHz with a bandwidth of 100 Mbit/s.In order to maximize the advantages of each frequency band and then improve users'perception through proper interoperability policies in FDD 700 MHz/TDD 2.6 GHz hybrid networking sites,this paper provides a switch solution of adding frequency-priority-based from 700 MHz to 2.6 GHz based on covering the switch of different frequencies.After this solution is implemented,the uplink and downlink speed of 2.6 GHz and 700 MHz for users increase by 5%to 8%,which significantly improves users'perception.关键词
