| description | The ultra-dense network (UDN) has been identified as an appealing solution to address the huge service demands in future 5G and beyond. In this paper, we propose an optimization design of UDN balancing user mobility and network densification, where the massive users are divided into different groups according to their moving speeds, and different groups are served by different subnets. This way, the UDN can adjust subnet parameters to meet the service demands using minimum resource. Specifically, we first present the objective of the UDN optimization, then look at the area spectral efficiency of each individual subnet if selected to serve users within a speed range, and finally carry out the joint optimization across multiple subnets. Numerical examples demonstrate that the proposed approach is effective and practical, meeting the service demands with the least bandwidth resource consumption. |
