“…Millimeter-wave communications [18][19][20][21][22] are gaining increasing interest in 5G as the largest chunks of spectra are available at the bands above 30 GHz. Due to broader contiguous bands the link level design can be somewhat relaxed and yet very high data rates are achievable.…”

5G system design is a complex process due to a great variety of applications and their diverse requirements. This article describes our experiences in developing a centimeter waves mobile broadband concept satisfying future capacity requirements. The first step in the process was the radio channel measurement campaign and statistical modeling. Then the link level design was performed tightly together with the radio frequency (RF) implementation requirements to allow as large scalability of the air interface as possible. We started the concept development at 10 GHz frequency band and during the project World Radiocommunication Conference 2015 selected somewhat higher frequencies as new candidates for 5G. Thus, the main learning was to gain insight of interdependencies of different phenomena and find feasible combinations of techniques and parameter combinations that might actually work in practice, not only in theory.

This letter presents an injection-locked 36 GHz frequency tripler (ILFT) for 5G applications. With the high order transformer based LC tank, over the target operating frequency range its phase response is flat at around 0 degree, and the injection-current is enhanced with a 3 rd harmonic LC tail filter, thereby achieving a wide locking range. Fabricated in a 65nm CMOS process, the ILFT consumes about 7.2 mW from a 0.6 V supply, and its core area without the output buffer and input matching network is only 0.25×0.4 mm 2 . With 0 dBm input injection power, the proposed ILFT achieves a locking range from 31.5 to 40.5 GHz (25%).

“…Recently, mobile communication has witnessed rapid developments, and 5G as well as multiple-input and multiple-output (MIMO) antenna technology have received considerable attention from researchers [1][2][3]. Moreover, accurate location-based services (LBS), such as emergency road assistance, location-based advertisements, location-based messaging and route navigation [4,5], have become popular topics of research.…”

Recently, positioning services have received considerable attention. The primary source of the positioning error is non-line-of-sight (NLOS) propagation. To address this problem, we propose a novel NLOS mitigation scheme, in which the geometric relationship between a base station and a mobile station is used. This makes it possible to identify range measurements corrupted by NLOS errors, and the mobile station can then estimate its position through line-of-sight (LOS) measurements. Moreover, the threshold of the NLOS detector is derived via a hybrid method using both the analytical derivation and computer simulation, which significantly reduces the difficulty of identifying thresholds. After identifying the NLOS measurements, a two-step weighted-least-squares algorithm is used to obtain the localization, in which both range and angle measurements are considered. The simulation results reveal that the proposed algorithm yields a high identification probability of NLOS measurements, which results in improved localization performance.
