“…In [180], the authors focused on the interference between the mobile satellite service and the fixed service in a maritime environment in the Ku band, and analysed the mobile earth station's transmit power, antenna gain, speed, and the propagation environment. More recently, the authors in [212] and [213] analysed the co-channel interference from maritime mobile earth station to 5G mobile service and suggested that a separation distance should be set to guarantee the QoS for 5G outdoor environments. Due to the long distance required to cover the sea surface, the propagation path needs to take into account the influence of the curvature of the earth.…”

As the fifth-generation (5G) mobile communication service is expected to operate in one of the 11 candidate frequency bands of 24.25-27.5 GHz, compatibility and coexistence with other adjacent wireless applications must be evaluated. In this paper, the adjacent channel interference (ACI) between Land-Earth Station in Motion (L-ESIM), 5G base station (BS), and user equipment (UE) operating in the adjacent frequency bands is assessed. The minimum coupling loss (MCL) method is used by considering the worst-case scenario to evaluate the effect of geostationary orbit-fixed satellite service's (GSO-FSS) frequency band of 27.5-29.5 GHz on the 5G radio access network (BS and UE) from L-ESIM. From the numerical simulations, minimum separation distances of 35 km and 12 km were recorded for the BS and UE to meet the maximum acceptable interference of -147 dBW/MHz. The obtained results will protect the 5G RAN from harmful interference by ensuring adjacent channel compatibility and coexistence with L-ESIM in their future deployment.

“…Several studies regarding the interfering link (a) have been conducted [17] [18] [19]. The authors of [17] presented a minimum separation distance between the M-ESIM and IMT-2020 by applying the MCL method. The analysis assumed that the M-ESIM is located on the East and West Sea of South Korea, which communicates with the FSS satellite.…”

The millimeter wave band is becoming popular for mobile broadband usage such as fifthgeneration (5G) mobile and mobile satellite services utilizing earth stations in motion (ESIM). According to the 2019 World Radiocommunication Conference (WRC-19), the 5G and ESIM systems will operate in adjacent frequency bands bounded by 27.5 GHz; therefore, the adjacent channel compatibility between ESIM and 5G should be verified. Both, the minimum coupling loss (MCL) and Monte-Carlo (MC) methods are applied to assess the worst and most practical interference effects, respectively, for all types of ESIM including the following: maritime ESIM (M-ESIM), land ESIM (L-ESIM), and aeronautical ESIM (A-ESIM). The distance and guard band between the two systems are indicated by the compatibility conditions. In addition to the conventional interference-to-noise ratio (I/N), the throughput loss of a 5G system is proposed to assess the performance degradation caused by the ESIM interference. Two orthogonal frequency division multiplexing (OFDM) waveforms are proposed to suppress ESIM power leakage into an adjacent channel. A mathematical expression regarding the power spectral density (PSD) and frequency dependent rejection (FDR) is derived for these waveforms, suggesting that the interference can be alleviated. A measured single carrier waveform of a commercial ESIM equipment is used as the benchmark against the proposed OFDM waveforms. The windowed OFDM is able to reduce the guard band by 50-77%. The results obtained for various elevation angles of the ESIM antenna are determined to be applicable to various regions globally.
