CoMP Transmission Approach for Seamless Connectivity in Vehicular Network through CRAN Architecture

Cloud Radio Access Network (CRAN) is considered the most preferable architecture for higher frequencies (especially for mm-Wave scenarios) due to Coordinated Multi-Point (CoMP) transmission facilities. However, its potential still needs to be explored, specifically in vehicular communication. The need for extensive pre-transmission processing in a CoMP-enabled framework may become outdated for highly mobile scenarios. To address this issue, we introduce a modified integrated CRAN architecture, offering several benefits. The proposed architecture leverages both micro-wave and mm-wave technologies collaboratively to enhance the coverage of running vehicles. Furthermore, this architecture serves vehicles according to their road type, which includes: i.) Urban Areas i.e., high-traffic scenario, where the vehicles are slow-moving, and ii.) Highway, i.e., light-traffic scenario, where the vehicles are moving at high speed. Through simulation results, we demonstrate the significant performance improvements of the proposed architecture compared to traditional CRAN-based transmission.
