Deskripsi
Abstract Coordinated Multi‐Point (CoMP) transmission in Cloud Radio Access Network (CRAN) requires a large amount of data transmission and processing within a coherence time window. Hence, CoMP transmission puts a lot of burden on the central processor and back‐haul unit. Also, establishing CoMP for high‐mobility users is challenging due to small coherence window and large beamforming overhead over mm‐Wave transmission. This paper proposes a two‐layer CRAN architecture with intelligent mm‐Wave and micro‐Wave allocation. A dual connectivity framework has been introduced to increase the coverage of high‐mobility users. Further, it is shown that the proposed scenario reduces the load on the central processor and central back‐haul. To avoid unnecessary handoffs, a mobility management algorithm is also proposed, which can provide seamless connectivity to the users irrespective of their velocity. Further, through simulation results, it is shown that the proposed network outperforms the existing CRAN framework.
