While there is clarity on the wide range of applications that are to be supported by 5G cellular communications, and standardization of 5G has now started in 3GPP, there is no conclusion yet on the detailed design of the overall 5G RAN. This article provides a comprehensive overview of the 5G RAN design guidelines, key design considerations, and functional innovations as identified and developed by key players in the field. 1 It depicts the air interface landscape that is envisioned for 5G, and elaborates on how this will likely be harmonized and integrated into an overall 5G RAN, in the form of concrete control and user plane design considerations and architectural enablers for network slicing, supporting independent business-driven logical networks on a common infrastructure. The article also explains key functional design considerations for the 5G RAN, highlighting the difference to legacy systems such as LTE-A and the implications of the overall RAN design.

Beamforming Design for Network Multiple-Input Multiple-Output (MIMO) Systems with Multiple Cooperating Base Stations
Kadan, Fehmi Emre; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2021-9-15)
New generation cellular systems are required to support high data rates. The performance of conventional systems with a single central base station is limited by inter-cell interference. Furthermore, the network densities grow exponentially and it is not cost-effective for operators to use a large number of fully equipped base stations in small areas. Using multiple cooperating base stations, each equipped with multiple antennas, inter-cell interference can be eliminated by a proper beamforming design. In t...
Analysis and design of dual-polarized wideband patch antennas electromagnetically excited with elevated wide strips /
Yılmaz, Adil Fırat; Alatan, Lale; Department of Electrical and Electronics Engineering (2015)
In communication systems like WiMAX, WLAN, 3G, 4G and LTE, design of wideband and dual polarized antennas are required. It is known that bandwidth of patch antennas can be broaden by using thick air substrates. The bandwidth can be further improved by using three dimensional feed strucutures that are electromagnetically coupled to the patch. In this thesis, microstrip patch antennas that are excited by elevated wide strips are studied. First, a linearly polarized antenna is considered and the effects of ant...
Differential K-band vector modulator IC design at 180 NM CMOS SOI process
Güngör, Ömer Fevzi; Aydın Çivi, Hatice Özlem; Koçer, Fatih; Department of Electrical and Electronics Engineering (2019)
Massive MIMO and beamforming are technologies that may enable ultrafast 5G network. They are predicted to be used widely in next-generation high capacity communication systems. In the implementation of beamforming and MIMO, the large number of antennas and RF control components are utilized. However; some challenges related to power consumption, control complexity, cost, and size of transceiver have arisen. Vector Modulator (VM) may be one possible effective solution to these challenges because it merges th...
Usage of device-to-device communication with multiple antennas at the cell edges Çoklu antenli cihazdan cihaza haberleşme yönteminin hücre kenarindaki alanlarda kullanimi
Erkan, Kerem; Yılmaz, Ali Özgür (2018-07-05)
5G technology is considered to bring dramatic improvements from the large scale data transmission to latency, from reliable data trasmission to energy efficiency. One significant improvement is expected in the communication rates between the mobile users at cell edges. Device-to-device (D2D) communication is an important technique to meet the higher data rates between the mobile users at cell edges compared to standard base station communication. In this paper, important decrease in the outage probability i...
User association and routing in UAV-supported HetNets
Tezergil, Berke; Onur, Ertan; Department of Computer Engineering (2022-1-24)
With the introduction of millimeter waves in 5G, using wireless backhaul has become feasible with higher performance comparable to that of fiber cables. Using unmanned aerial vehicles as small cells enabled many use-cases by reducing the average link length and increasing the line-of-sight probability. In this work, a heterogeneous network with users, flying small cells on unmanned aerial vehicles, and macro base stations are considered. We introduce two main problems: establishing backhaul routes for small...
