The objective of this tutorial is to provide a comprehensive guide on the emerging trends in mobile applications, and the challenges of supporting such applications with 4G technologies. We will describe requirements for 5G systems on data rate, capacity, latency, power, etc., and explore candidate technologies currently being considered to meet 5G requirements.

T-02: Massive MIMO for 5G: Fundamentals and Recent Theory
Room: ICC Capital Suite12
- Massive MIMO for 5G: Fundamentals and Recent Theory
-
The next generation wireless networks need to accommodate 1000x more data traffic than contemporary networks. Since the spectrum is scarce in bands suitable for coverage, the main improvements need to come from spatial reuse of spectrum; many concurrent transmissions per area unit. This is achieved by massive MIMO technology, where the access points are equipped with hundreds of antennas. These antennas are phase-synchronized and can thus radiate the data signals to multiple users such that each signal only adds up coherently at its intended user. In recent years, massive MIMO has gone from a theoretical concept to one of the most promising 5G-enabling technologies, because it can achieve 5G-like throughput by upgrading existing sites—instead of installing orders of magnitude more access points. This tutorial introduces the basic communication theory and motivation behind massive MIMO, as well as recent theoretical results on power control, energy efficiency, and impact of hardware impairments.pp. 9421-9425

T-13: Emerging Concepts and Technologies Toward 5G Wireless Networks
Room: ICC Capital Suite17
- Emerging Concepts and Technologies Toward 5G Wireless Networks
-
Despite the recent advances in wireless technologies, the wireless community faces the challenge of enabling a further traffic increase of around 1,000 times, latency reduction of around 100 times, device increase of around 100 times in the next 15 years or so, while no customer is willing to pay more for the wireless pipe itself: the so called "traffic-revenue decoupling". Moreover, many experts warn that the low-hanging fruit in wireless research (especially in information theory, communications theory, and signal processing) have already been collected. While the research community is full of ideas (as usual), many of these ideas are either not-too-relevant (i.e., not in the bottleneck areas) or they are in areas in which progress toward a tangible implementation is too slow.pp. 9472-9476

T-17: Cloud Radio Access Networks: Principles, Challenges, and Technologies
Room: ICC Capital Suite17
- Cloud Radio Access Networks: Principles, Challenges, and Technologies
-
Radio access network (RAN) is the key segment of the mobile operators that provides over-the-air packet services to mobile users. Recently, cloud RAN (C-RAN) is emerged as a new architecture to meet the cost, energy, and bit rate concerns for mobile operators and users. Unlike typical RANs, the C-RAN decouples the baseband unit (BBUs) from the radio units by locating the BBUs at the high performance cloud infrastructure. The key insight is that if the network capacity is limited by the interference and its workload is changing over time and space, then centralizing radio processing can dramatically increase the network capacity and reduce the overall energy consumption. This tutorial aims at providing a complete C-RAN picture, a well-balanced state-of-the-art research topics and advances, and the role of C-RAN in 5G systems. It is organized in four technical parts covering principles, challenges, key technologies, proof-of-concept prototypes and field trials in C-RAN.pp. 9490-9494
