“…In order to establish a stable link between the BS and the MT, the channel estimation, and hence the beam alignment, must be completed or joined with a beam tracking scheme in order to track the variations in AoDs/AoAs at the receiver. Despite the efforts deployed in this area [205], [206], some extensive research is needed to develop practical and fast estimation/tracking algorithms for mmWave channels. • Quantization errors: In the literature, the beam steering directions are assumed to be quantized, i.e.…”

The fifth-generation (5G) of cellular networks and beyond requires massive connectivity, high data rates, and low latency. Millimeter-wave (mmWave) communications is a key 5G enabling technology to meet these requirements thanks to its technical potentials that can be integrated with other 5G enablers such as ultra-dense networks (UDNs) and massive multiple-input-multiple-output (massive MIMO) systems. However, some technical challenges, which are mainly related to specific characteristics of mmWave propagation, must be addressed. All the aforementioned points will be discussed in this paper before presenting the different existing architectures of massive MIMO mmWave systems. This survey mainly aims at presenting a comprehensive state-of-the-art review of the channel estimation techniques associated with the different mmWave system architectures. Subsequently, we will provide a comparison among existing solutions in terms of their respective benefits and shortcomings. Finally, some open directions of research are discussed, and challenges that wait to be met are pointed out.

“…It has been shown that by using the previously estimated beams as the prior information, the number of pilots required can be minimized to an acceptable level. This technique, commonly referred to as beam tracking, has recently raised huge research interests in mobile mmWave communications [4], [9]. As shown in Fig.…”

“…The motivation for integrating radar sensing and communication naturally arises in the vehicular network, which not only enhances the efficient utilization of both the spectral and signalling resources, but also enables the beneficial cooperation between the two functionalities. In particular, with the aid of the radar sensing, the pilots and the feedback loop required in the conventional mmWave beam tracking schemes [4], [5] are no longer needed, thus reducing the processing latency, which is key to vehicular network operated in the high-mobility environment.…”

In Part I of this three-part tutorial on dualfunctional radar-communication (DFRC), we overviewed the fundamental elements of DFRC. As Part II of the tutorial, this letter overviews the state-of-the-art (SoA) in DFRC, with a particular emphasis on the use of the technique for seamless connectivity in the vehicular network. We commence by introducing the conventional beam tracking approaches for millimeter wave (mmWave) communication systems, based exclusively on communication signalling and feedback, followed by the DFRC based schemes tailored for the vehicular network. Finally, we evaluate a number of SoA DFRC schemes through comparative simulations.

“…Fortunately, the shorter wavelength in the mmWave band allows the deployment of a larger antenna array, providing a considerable beamforming gain to compensate for the path loss [2]- [6]. For a hybrid or analog beamforming (ABF) system as cost-efficient ways to obtain this array gain, misalignment of beam direction may not only degrade the effective receiving power, increasing mutual interference, but also lead to the loss of beam observations due to the users' mobility, especially in fast-varying environments [7], [8]. Therefore, accurate beam tracking is crucial for serving fast-moving users in mmWave mobile communication system.…”

The sparsity and the severe attenuation of millimeter-wave (mmWave) channel imply that highly directional communication is needed. The narrow beam produced by large array requires accurate alignment, which is difficult to achieve when serving fast-moving users. In this paper, we focus on accurate two-dimensional (2D) beam and channel tracking problem aiming at minimizing exploration overhead and tracking error. Using a typical frame structure with periodic exploration and communication, a proven minimum overhead of exploration is provided first. Then tracking algorithms are designed for three types of channels with different dynamic properties. It is proved that the algorithms for quasi-static channels and channels in Dynamic Case I are optimal in approaching the minimum Cramér-Rao lower bound (CRLB). The computational complexity of our algorithms is analyzed showing their efficiency, and simulation results verify their advantages in both tracking error and tracking speed. INDEX TERMS Millimeter-wave mobile communication, beam and channel tracking, 2D phased antenna array, optimal exploring beam, Cramér-Rao lower bound.
