“…The mm-wave transmission is highly directional and sensitive to the misalignment of beams. Therefore, the researchers and standardization industries flourished new approaches such as Beamforming and Beamsteering [237,238],. The proposed techniques helped avoid the interference phenomenon in the massive MIMO system and provide dedicated narrow beams to each user yet regular large multiple beams from the antennas produce IBI.…”

In the modern technological world, wireless communication has taken a massive leap from the conventional communication system to a new radio communication network. The novel concept of Fifth Generation (5G) cellular networks brings a combination of a diversified set of devices and machines with great improvement in a unique way compared to previous technologies. To broaden the user's experience, 5G technology provides the opportunity to meet the people's potential necessities for efficient communication. Specifically, researchers have designed a network of small cells with unfamiliar technologies that have never been introduced before. The new network design is an amalgamation of various schemes such as Heterogeneous Network (HetNet), Device-to-Device (D2D) communication, Internet of Things (IoT), Relay Node (RN), Beamforming, Massive Multiple Input Multiple Output (M-MIMO), millimeter-wave (mm-wave), and so on. Also, enhancement in predecessor's techniques is required so that new radio is compatible with a traditional network. However, the disparate technological models' design and concurrent practice have created an unacceptable intervention in each other's signals. These vulnerable interferences have significantly degraded the overall network performance. This review article scrutinizes the issues of interferences observed and studied in different structures and techniques of the 5G and beyond network. The study focuses on the various interference effect in HetNet, RN, D2D, and IoT. Furthermore, as an in-depth literature review, we discuss various types of interferences related to each method by studying the state-of-the-art relevant research in the literature. To provide new insight into interference issue management for the next-generation network, we address and explore various relevant topics in each section that help make the system more robust. Overall, this review article's goal is to guide all the stakeholders, including students, operators, engineers, and researchers, aiming to explore this promising research theme, comprehend interferences and their types, and related techniques to mitigate them. We also state methodologies proposed by the 3 rd Generation Partnership Project (3GPP) and present the promising and feasible research directions toward this challenging topic for the realization of 5G and beyond network.

“…However, windowing increases the beamwidth [7] and ultra-low sidelobes requires precise control of the power applied to each antenna element. Moreover, the amplitude control deteriorates the power amplifier (PA) efficiency and limits the achievable effective isotropic radiated power (EIRP) in the [24] transmitter (Tx) while it also affects to the overall noise figure of the receiver (Rx) [25].…”

Large-scale phased arrays need to combine weighted signals from multiple sub-arrays either in analog or in digital domain. Sub-arrays are preferably implemented modularly with integrated circuits placed next to the associated antennas. In order to enable flexible and scalable combining networks of several mmWave sub-arrays, this paper presents a wideband receiver module that provides the cartesian combining of beamforming weights for one sub-array at IF. Furthermore, it allows interference cancellation between subarrays or combining multiple sub-arrays. It also provides filtering before ADCs to support current and foreseeable 5G channel bandwidths up to 800MHz. The receiver is operating at 2-4GHz IF frequency range and has more than 400MHz baseband bandwidth, a noise-figure of 5.5dB,-6dBm 1dB compression point and +3dBm in-band IIP3. In addition, overthe-air measurements are performed, showing 26dB of interference cancellation between the sub-arrays. The prototype is implemented using 45nm CMOS PDSOI.
