“…of 5G wireless technology, various efficient antennas have been reported. High gain can be achieved by using antenna array techniques to overcome signal fading issue due to poor weather condition in both line-of-sight (LOS) and non-line-ofsight (NLOS) communication [50]. Wideband and multiband operation can be achieved by frequency reconfiguration mechanism.…”

With the supersonic growth of mobile data demand, the fifth generation (5G) mobile network would exploit the extensive amount of spectrum in the millimeter-wave (mm-Wave) bands to tremendously increase communication capacity. There are conceptual differences between mm-Wave communications and other existing communication systems, in terms of high propagation loss, directivity, and sensitivity to blockage. These characteristics of mm-Wave communications present several challenges to completely exploit the potential of mm-Wave communications, including integrated circuits and system design, interference management, spatial reuse, anti-blockage, and dynamics control. 5G mobile communication systems with sub-6 GHz and millimeter-wave bands are already replacing 4G and 4.5G systems as an evolution towards higher-speed mobile communication and wider bandwidth. From the hardware perspective, the 5G-band causes the miniaturization of RF components including the antennas. In this article, an overview of recent research is presented that discusses design challenges and measurement considerations for various types of compact 5G antennas.

“…Generally, the transmission power of macro BSs is much larger than that of pico BSs, and as a result, many users will still receive the strongest signal from the macro BS even in hotspots. The RE scheme is to favor the selection of low power BSs by introducing a bias to the association threshold for low power BSs [23]. Due to the smaller coverage, lower power BSs can provide more resource blocks to each user than macro BSs.…”

“…Due to the smaller coverage, lower power BSs can provide more resource blocks to each user than macro BSs. References [23][24][25] have shown that RE can achieve load balancing and enhance performances of networks without a loss of average user throughput. For example, in a two-tier HetNet, due to the bias, users are more likely to connect to the pico BSs than the macro BSs even if p 1 h 1 r −α 1 1 > p 2 h 2 r −α 2 2 .…”

Heterogeneous cellular networks (HetNets) consist of different tiers of base stations (BSs) to meet the ever-increasing mobile traffic demand. Due to the random deployment of BSs, Poisson point process (PPP) is often used to model the BS distribution. However, low power small cells are usually clustered around the popular areas, and PPP can not reflect such a feature. To this end, we in this paper consider base station (BS) cooperation and analyze user rate and energy efficiency of HetNets based on a Poisson cluster process (PCP). A calculable formula for the average data rate (or spectral efficiency) and its approximated closed form are derived. Based on this closed form, a power minimization solution with certain spectral efficiency constraint is proposed, and the optimal cooperation radii are derived. Furthermore, we analyze spectral efficiency under a limited number of cooperative BSs in a two-tier network. Finally, we propose a range expansion (RE) scheme and examine the impact of this scheme. The theoretical analyses are verified by simulation results.
