In millimeter wave (mmWave) communication systems, existing hybrid beamforming solutions generally require a large number of high-resolution phase shifters (PSs) to realize analog beamformers, which still suffer from high hardware complexity and power consumption. Targeting at this problem, this article introduces a novel hardware-efficient hybrid precoding/combining architecture, which only employs a limited number of simple phase over-samplers (POSs) and a switch (SW) network to achieve maximu...

It is widely acknowledged that the development of traditional terrestrial communication technologies cannot provide all users with fair and high quality services due to the scarce network resource and limited coverage areas. To complement the terrestrial connection, especially for users in rural, disaster-stricken, or other difficult-to-serve areas, satellites, unmanned aerial vehicles (UAVs), and balloons have been utilized to relay the communication signals. On the basis, Space-Air-Ground Inte...

While enjoying the convenience brought by the Internet of Things (IoT), people also encounter many problems with wireless sensor networks (WSNs), the foundation of IoT. Security problems are especially of concern. In this article, we focus on location privacy, which is a major security issue in WSNs, and propose a k-means cluster-based location privacy (KCLP) protection scheme for IoT. To protect the source location, fake source nodes are used to simulate the function of the real sources. Then, ...

Wireless communications with UAVs offer a promising solution to provide cost-effective wireless connectivity and extend coverage. In recent years, the area of wireless communications for UAV system design and optimization has been receiving enormous attention from the research community. However, there are still existing challenges that are far from solved. To cope with those challenges, researchers have been exploring the applicability of game-theoretic approaches. This article surveys the exis...

The explosive growth of mobile devices and the rapid increase of wideband wireless services call for advanced communication techniques that can achieve high spectral efficiency and meet the massive connectivity requirement. CR and NOMA are envisioned to be important solutions for fifth generation wireless networks. Integrating NOMA techniques into CRNs has tremendous potential to improve spectral efficiency and increase system capacity. However, there are many technical challenges due to the sev...

MmWave and VLC are two promising technologies for future 5G indoor communications to enable gigabit-per-second data transmission and to meet the ever increasing capacity requirements. Only with a solid understanding of the channels on mmWave and VLC can researchers and industry practitioners further explore the appropriate architectures and efficient communication schemes. In this article we focus on two recent indoor channels in future 5G networks based on mmWave and VLC. The article first disc...

Driven by a massive surge in digitization and customization, so-called vertical industries are expected to be a major beneficiary of the 5G of mobile networks. The use cases of such vertical industries define qualitative and quantitative requirements unprecedented in the history of mobile network development. Autonomous vehicles, traffic light control, video surveillance, and IIoT, to only name a few, introduce challenging requirements regarding both conventional performance metrics, such as thr...

Mobile data traffic has dramatically increased by a factor of around 100 over the last five years, while it is still expected to grow exponentially in the near future. Evidence indicates that the repetitive downloading of popular contents accounts for the increase in wireless traffic. This has consequently led to the development of edge caching technology for efficiently mitigating redundant transmissions from backbone networks by pre-caching frequently requested data at radio access networks. A...

Full-duplex radios have become a topic of increased interest in the wireless communications community. As part of this development, many efforts were directed to passively decrease the self-interference level at the antenna outputs. However, in many proposed solutions transmission and reception occur through different propagation channels. This article demonstrates and quantifies the negative impact of channel differentiation on pivotal applications of full-duplex radio, such as cognitive radio....

A range of efficient wireless processes and enabling techniques are put under a magnifier glass in the quest for exploring different manifestations of correlated processes, where sub-Nyquist sampling may be invoked as an explicit benefit of having a sparse transform-domain representation. For example, wide-band next-generation systems require a high Nyquist-sampling rate, but the channel impulse response (CIR) will be very sparse at the high Nyquist frequency, given the low number of reflected p...
