Previous Next Millimeter waves: How we got here, the physical challenges, and 5G opportunities In modern day engineering, the best solution for a challenge is usually considered to be one that is both economically viable and time-saving. In this communication age, smartphones are basically small handheld computers and our household electronics are starting to communicate both with them and between themselves. Spectrum sensing consists of finding instantaneous holes in the spectrum so different devices can share and use it according to the real, immediate availability. Government policies around the world regarding EM spectrum are now actively being revised in order to let researchers and industry players adapt new solutions and technologies to our modern world needs. The technology has evolved; antenna gain capabilities have dramatically improved with the arrival of semiconductor technology along with other improvements. But the available usable spectrum has remained the same… or has it? In the roughly years of wireless telecommunications history, the exploration of new frequency regions has always led to technological advances. Today, research based in the EHF band or millimeter wave band is focused in finding its advantages and exploitability for radio communications. High frequencies are very interesting compared to the traditional lower bands for two reasons[3]: 1. Larger bandwidth availability 2. Smaller antenna dimensions for a fixed gain, or higher gain for a given antenna size. Larger bandwidth is directly proportional to higher data transfer rates. Additionally, a larger bandwidth enables capabilities like wideband spread-spectrum systems for reduced multipath and clutter and systems with a high immunity to jamming and interference. Obstacles Millimeter waves open up more spectrum but until recently few electronic components were able to generate or receive millimeter waves, so the spectrum remained unused.

D2D communications should be enabled in the mmWave cellular systems to support the applications that involve discovering and provide communication with nearby devices.

Smaller antenna dimensions for a fixed gain, or higher gain for a given antenna size. Larger bandwidth is directly proportional to higher data transfer rates.

Additionally, a larger bandwidth enables capabilities like wideband spread-spectrum systems for reduced multipath and clutter and systems with a high immunity to jamming and interference.

Obstacles Millimeter waves open up more spectrum but until recently few electronic components were able to generate or receive millimeter waves, so the spectrum remained unused.

Generating and receiving millimeter waves is a challenge, but the biggest and most challenging factor with these high frequencies is the travelling media. Poor foliage penetration has been observed but the biggest challenges are atmospheric and free-space path loss. Millimeter waves are governed by the same physics as the rest of the radio spectrum and as such, they have limitations related to their wavelength. The shorter the wavelength, the shorter the transmission range for a given power.

Rain, fog, and moisture in the air make the signal attenuation very high. However, for the operators, the capital and operational expenditures increase significantly as the base station BS density increases. In this regard, a cost-effective 5G radio access network RAN solution is of great interest.

In this thesis, Device-to-Device D2D relaying and low-complexity mmWave system architectures are considered to fulfill this objective. The main goal of D2D relaying is to create a new type of network connectivity to carry mobile traffic, so that user experience consistency is improved without a need of ultra-dense BS deployment.

The D2D relaying connectivity is extremely useful in mmWave bands as mmWave signals can be easily blocked by various obstacles.

D2D relaying should be subject to network control by a RAN controller. We consider a hierarchical control framework to perform D2D discovery, relay selection, mmWave beam selection, resource allocation and interference management.

With this framework, D2D relaying in four practical network scenarios is considered, and low-complexity algorithms are developed to manage D2D relaying. In addition to D2D relaying, we also consider developing low-cost mmWave BSs for ultra-dense mmWave network deployments.
