With the development of 5 G construction

the use of part of 4 G as 5 G has reduced the available frequency bands for 4 G. At the same time

users’ demand for high-speed mobile data services continues to grow

and the limited spectrum resources are increasingly severe. In combination with network development trends

FDD900 M

as a long-term use of 4 G frequency band in the future

needs to focus on improving its service carrying capacity. This article explores the overall processing flow of FDD900 M bearer enhancement

focusing on parameter optimization and interference optimization

and proposes personalized optimization strategies to effectively solve 4 G network coverage and capacity issues

thereby improving 4 G network service quality.
