Abstract:

The use of very high frequencies (e.g., THz) in cellular mobile communications results in smaller cell sizes due to significant radio propagation loss, ultimately leading to the formation of ultra-dense networks (UDN). Additionally, due to their ultra-wideband nature, these frequencies are divided into multiple component carriers (CCs) to efficiently utilize the available radio resources. Applying carrier aggregation (CA) technology to these CCs enables high-capacity data transmission. However, the performance at the cell edge can be severely degraded or subject to significant variations. To address this issue, technologies such as coordinated multi-point (CoMP) or dual active protocol stack (DAPS) have been introduced, enabling some improvements in user plane (UP) performance. Nevertheless, when considering ultra-high-speed user equipment (UE) or UDN environments, it is still essential to consider cell-edge performance improvements not only on the UP side but also on the control plane (CP) side. In this paper, we assume an overlaid cell structure (OCS) environment where individual layer cell groups are established, allowing ensuring that cell edges between layers do not overlap and specific master nodes (MNs) to move within specific layers. Additionally, we propose the multiple control plane joint operation (MCPJO) method, which utilizes two or more control planes and wireless connectivity with two or more master nodes. This environment and method offer significant improvements in cell-edge performance by reducing fluctuations in user capacity and enhancing handover movement stability.
