| Summary: | With the rapid growth of large traffic demand services such as AR/VR, it is imperative to increase the peak rate of single user.The basic principles of multi-band joint transmission technology in different protocol versions were mainly studied, such as carrier aggregation, supplementary uplink and dual connectivity, which could improve the performance of single user peak rate.Then the deployment requirements of different technologies to the network were analyzed, especially for the non-co-BBU or non-co-RRU scenarios to do qualitative performance analysis, subsequent quantitative analysis or test verification will further verify the accuracy of qualitative analysis.After that, the upstream and downstream peak rate and edge rate corresponding to different technologies were calculated, including performance comparison of different protocol versions.At last, the industry status quo of different technologies was introduced. |
