Architecture and features for 5G mobile personal cell

The next generation (5G) mobile communication systems are targeting 1000× growth in aggregate data rate. To achieve that data rate, 5G mobile personal cell (mPC) is an emerging technology to provide ubiquitous connectivity to the users according to the traffic load and situations. In this paper, we provide a brief survey on the architecture and features for the 5G mobile personal cell in the context of the 3GPP LTE-A. More specifically, this paper highlights the key differences in the mPC architecture from the existing 3GPP LTE-A architecture. In mPC architecture, there is an additional personalized cell domain that helps users to ubiquitously connect with less transmission delay by supporting high mobility and data rate. Moreover, the key features of mPC such as its load balancing capability, capacity boosting, capability to cope with the disasters situations, and seamless mobility support regardless of the cell types and radio access technologies (RATs) are discussed. In addition, the suitable deployment scenario for the mPC is also discussed. Finally, we present possible challenges and point out the directions for mPC research.
