“…In terms of field experiments, observations of CoMP implementation within C-RAN demonstrate UL CoMP gain between 50% and 100% in [27]. A field trial experiment of UL intra-site CoMP in one of the business district of Belgrade, Serbia is given in [28] where an improvement in terms of UL data throughput is demonstrated. In our recent work of [29], we have investigated the performance improvement of SFN deployment using C-RAN in one of the real-world experimental test site of a MNO in Istanbul, Turkey.…”

According to International Mobile Telecommunication's requirements for 2020, next generation cellular networks such as 5G need to meet certain Key Performance Indicator (KPI) targets. Centralized-Radio Access Networks (C-RAN) is a novel technique that can address growing capacity needs of Mobile Network Operators (MNOs) due to ever increasing demands of their users. In order to meet stringent requirements of next generation cellular networks, C-RAN enabled techniques have attracted a lot attention due to their efficient spectrum (band, bandwidth) utilization (e.g. via carrier aggregation (CA)), spectrum efficiency (e.g. via Inter-Cell Interference Coordination and cancellation using Coordinated MultiPoint (CoMP) Transmission/Reception). In this paper, we investigate three different CA scenarios along with their benefits and limitations from the perspective of MNO. Additionally, we analyze inter-Baseband Unit (BBU) uplink (UL) CoMP feature as a real-world experimental C-RAN implementation in an operational suburban site of Istanbul in Turkey. Quantitative CA performance measurements demonstrate performance comparison of the considered three CA scenarios, and depending on each MNO's strategy, different CA gains are observed (e.g. LTE 1800 Mhz
