Macro-assisted data-only carrier for 5G green cellular systems


As the industrial operation of 4G systems is speeding up worldwide to fulfill the increasingly explosive growth of mobile Internet within the 20twenty era, a great many R&D efforts targeting the following generation wireless systems (5G) have been launched. With densely deployed tiny cells in an exceedingly heterogeneous network, the excessive signaling overhead of conventional carrier style greatly degrades system performance. A brand new carrier designed for little cells in the next generation system can be highly useful toward a inexperienced communication network. In this text, we tend to propose a macro-assisted information-only carrier for future 5G networks from a inexperienced prospective. With the help of macro base stations, control channel overhead, and cell-specific reference signals for small cells will be minimized to achieve a pure-knowledge carrier. Under this design, key procedures are designed as well as tiny cell identification and access, synchronization, hand over, and tiny cell sleeping. Furthermore, to evaluate the potential of our proposed scheme, an entire system and link-level simulation platform in keeping with the present 3GPP LTE normal is constructed. The simulation results show that our proposed systems, achieving significant performance enhancement of signaling overhead, can cause additional than 17 percent throughput improvement and ninety % energy potency gain over the current LTE HetNet with on-off strategy implemented. The proposed scheme seems to be highly engaging as half of the longer term 5G inexperienced mobile networks.
