Almost all cellular mobile communications including first generation analog systems, second generation digital systems, third generation WCDMA systems, and fourth generation OFDMA systems use Ultra High Frequency (UHF) band of radio spectrum with frequencies in the range of 300MHz-3GHz. This band of spectrum is becoming increasingly crowded due to spectacular growth in mobile data services. The portion of the RF spectrum above 3GHz has been largely uxexploited for commercial mobile applications. In this tutorial, we discuss propagation and device technology challenges associated with this band as well as its unique advantages such as spectrum availability and small component sizes for mobile applications. We also present a practical millimeter-wave mobile broadband (MMB) system that can achieve multi-Gbps data communications in an urban environment.

T2: Cooperative Wireless Communications

Instructor: Lajos Hanzo, University of Southampton, UK

 

This course reviews the current state-of-the-art and proposes a number of novel relaying and cooperation techniques. An important related issue is the availability or the absence of accurate channel information. This design dilemma leads to the concept of coherent versus non-coherent detection at both the relays and at the destination. Similarly, the related initial synchronization issues also have to be considered. Naturally, when using hard-decisions in the transmission chain, we discard valuable soft-information, which results in an eroded performance, albeit also reduces the complexity imposed. Hence the hard- versus soft-decoding performance trade-off will also be explored in the course, along with the benefits of interleaved random space-time coding invoked for multi-source cooperation.

As mobile networks continue to grow and converge with the Internet, new wireless devices and their use are outnumbering the use of fixed network. Mobility management needs to meet the requirements of existing and emerging network technologies. It may be supported in different layers of the network protocol stack. At the IP layer, Mobile IP, an IP-based mobility management, has the advantage of being applicable in any IP-based network, but is faced with many deployment challenges. Numerous variants of Mobile IP have been proposed to address these challenges in different network environments. The real test however is in deployment. Both 3GPP and WiMAX have adopted only network-based mobility management, which does not require changes to the IP stack of the mobile hosts. Reasearch in mobility management has become more active, especially with the mobile networks continuing to evolve from hierarchical towards more flattened network. This tutorial presents the basics, recent advances, and future directions for mobility protocols at various layers (e.g., network, transport and application). It provides a taxonomy of mobility protocols. It illustrates a few scenarios to describe applicability of mobility protocols to various network environments. It goes through the best practices, and then provides the research directions.

The 3rd Generation Partnership Project (3GPP) is currently working on the standardization of the next evolution of LTE, known as LTE-Advanced (also referred to as LTE release 10). In order to fulfill the demanding requirements of LTE-Advanced (which include features such as peak data rates of 1 Gbps in the downlink and 500Mbps in the uplink, low latency, support for mobility up to 350km/h, and good throughput guarantee even to cell edge users), several technological enhancements are proposed. Relaying is one of these key technological enhancements, along with carrier aggregation, improved multiple input multiple output (MIMO) antenna schemes, and coordinated transmission and reception between different base stations. The tutorial starts with a general introduction on LTE-advanced and relaying. The different types of relaying, the possible deployment scenarios and performance results illustrating the coverage/capacity as well as cost benefits of relaying are then discussed. After that, the main focus will be put on the architectural and protocol aspects for realizing relaying in LTE-advanced networks. The chosen architecture for LTE-advanced release 10 is then described along with the reasons behind the choice based on several issues such as support for QoS, mobility, complexity, standardization impact, scalability, and security. The tutorial concludes by summarizing the current status of relaying standardization in 3GPP LTE-advanced release 10 and the open issues that are expected to be addressed in future releases.

The tutorial addresses strategies and principles of PHY layer coding and signal processing fully respecting and utilizing knowledge of the network structure. This technique substantially increases the overall network throughput, efficiency and reliability. Wireless Network Coding (WNC) is a general framework for PHY layer coding and processing strategies in which PHY behavior at a given node depends on its position in the network topology, and the signal-level processing/decoding uses multiple paths between source and destination. The decoding and relaying strategies utilize their knowledge of the contents and structure of the complementary side-information (“friendly interference”) available at various nodes. The tutorial will address the fundamental principles of WNC put into a context of network information theory with a comprehensive classification of the strategies. A section on advanced design and techniques will cover particular coding and processing designs and their respective properties. We will also address selected hot research topics and open problems
