In this paper, we investigate the coverage performance and energy efficiency of multi-tier
heterogeneous cellular networks (HetNets) which are composed of macrocells and different …

The roll-out phase of the next generation of mobile networks (5G) has started and operators
are required to devise deployment solutions while pursuing localization accuracy …

Small heterogeneous cells have been introduced to improve the system capacity and
provide the ubiquitous service requirements. In order to make flexible deployment and …

As upcoming, beyond-5G (B5G) wireless network generations are expected to deliver much
better performance than existing solutions, Reconfigurable intelligent surfaces (RISs) are …

在現今的網路中, 對於高傳輸率以及低延遲的需求不斷增加, 為了滿足這些需求,
第五代行動通訊(5G) 使用3 到100 GHz 的頻帶進行傳輸. 更大的頻寬解決了高傳輸率以及低 …

隨著科技突飛猛進的發展, 網路不只是人類生活密不可分, 連裝置對裝置之間也需要透過網路來
做通訊. 在未來的二十年裡, 這些通訊需求的爆炸性成長, 讓現今的網路技術無法負擔, 5G …

In this thesis, the study of small cell deployment in heterogeneous networks is presented.
The research work can be divided into three aspects. The first part is user data traffic …
