“…Hence, the TRP ACLR (or absolute ACP (Adjacent Channel Power) is independent on the intended transmission direction. However, as it has been shown and discussed in [5], [8]- [12], the ACP may, in some cases, experience the array response differently than the fundamental signal. Such behavior can appear when multiple parallel nonlinear array elements (e.g.…”

Large antenna arrays used for compensating the millimeter wave (mmW) path loss gives interesting perspectives for considering out-of-band emissions and reception signals to be direction dependent. In addition, coexistence of lower frequency and mmW systems set special requirements for both conventional cellular and mmW systems. This paper presents discussion on these two cases as the most important out-of-band interference scenarios in fifth generation systems. Effects of intermodulation and adjacent channel leakage are discussed in both mmW beamforming transceiver and receiver, respectively. It is concluded that distortion is behaving differently in multi-antenna transmitter than at the receiver. Over-the-Air (OTA) measured and simulated examples of the nonlinear behavior of an array are given for receiver and transmitter, respectively. Furthermore, smart array linearization scheme given as a reference provides new perspective to consider the direction dependent out-of-band distortion as a part of the future cellular standards.

“…is paper, however, varies from previous studies in many ways. First, the results obtained by some previous researchers [7][8][9] focused on the relationship between the advanced IMTsystem, also called the 4G system, and FSS; the target frequency was mainly from a 3.5 GHz, non-mmWave band, which is obviously different from the current research goals. Second, unlike the study undertaken in the current work, other previous research [10][11][12][13] has primarily considered the 5G scenario to be a traditional enhanced mobile broadband (eMBB) scenario rather than a 5G IoT scenario, such as ultrareliable and low latency (URLLC) and massive machine-type communications (mMTC).…”

It is a promising way to successfully operate the fifth generation (5G) system with Internet of Things (IoT) in potential mmWave spectrum bands. This paper investigates the intelligent co-channel coexistence between the 5G IoT system and the fixed-satellite service (FSS) system at 40 GHz. The key issue, as identified, is the accurate estimation of interference based on mmWave propagation characteristics. Our simulation results reveal that interference from the 5G IoT system into the FSS ground stations can be kept below the protection threshold by considering different deployment parameters, such as antenna patterns, height of Earth station (ES), and separation distance.

“…An SDR architecture for next-generation satellite networks, further including the software-defined networking (SDN) and network function virtualization (NFV) paradigms, has been described in [13], together with a possible roadmap for its deployment and integration with the 5G infrastructure. The co-channel interference at 28 and 70 GHz between 5G systems and mmWave fixed satellite services (FSSs) has been studied in [14], showing that protection mechanisms may be introduced in the 5G devices to mitigate the interference towards the FSS without significantly affecting the 5G network performance.…”

This paper presents a novel network architecture for an integrated nanosatellite (nSAT)-5G system operating in the millimeter-wave (mmWave) domain. The architecture is realized adopting a delay/disruption tolerant networking (DTN) approach allowing end users to adopt standard devices. A buffer aware contact graph routing algorithm is designed to account for the buffer occupancy of the nSATs and for the connection planning derived from their visibility periods. At the terrestrial uplink, a coded random access is employed to realize a high-capacity interface for the typically irregular traffic of 5G users, while, at the space uplink, the DTN architecture is combined with the contention resolution diversity slotted Aloha protocol to match the recent update of the DVB-RCS2 standard. To achieve a reliable testing of the introduced functionalities, an accurate analysis of the statistic of the signal to interference-plus-noise ratio and of the capture probability at each mmWave link is developed by including interference, shadowing, fading, and noise. The application of the designed architecture to data transfer services in conjunction with possible delay reduction strategies, and an extension to inter-satellite communication, are finally presented by estimating the resulting loss/delay performance through a discrete-time discrete-event platform based on the integration of Matlab with Network Simulator 3.
