In the past decade, the mobile communications industry in China has developed rapidly with strong growth in mobile subscribers. China has the largest number of mobile subscribers (over 950 million in October 2012) in the world. In 2012, mobile industry revenue in China is expected to be over US$200 billion and accounts for about 75% of revenue of China's telecommunication sector as a whole. There is a huge demand for high data rate mobile services in China. On the other hand, the investment by China government and industry in the research and development for future mobile communication technologies has been increased significantly in recent years. For example, the five-year research budget in so-called “National Key Integrated Project in Future Broadband Mobile Communications” is over US$10 billion.

This Panel will bring together five prestigious speakers who will present their views as to what challenges and technologies in R&D are and how they are to be solved.

In the past few years, C-RAN has been generating increasing heated interest from both industry and academia. Featuring Centralized processing, Cooperative radio, Cloud computing and Clean RAN system, C-RAN claims such advantages as fast network deployment, reduction of TCO cost and improved network performance and efficiency. While the success has been quite phenomenal up to date, the new paradigm still faces a plethora of challenges to be solved before it can be deployed in large scale, which requires exploiting the synergy from industry and academia.
With the contribution of key luminaries, the specific C-RAN panel aims to provide a unique platform to share the latest progress, to exchange their viewpoints on technology innovation, future application and so forth in the C-RAN paradigm. The topics of interest to be discussed include but are not limited to:
  • Flexible, scalable and reliable large-scale BBU pool design
  • Efficient fronthaul solutions
  • Integration of virtualization with C-RAN
  • Cloud computing technology in C-RAN
  • Large-scale cooperative communication

The provision of smartphones and tablets caused paradigm shift on user experiences.  Simultaneously, it is driving the drastic growth of mobile data traffic. It is predicted that there will be 500 times amount of mobile traffic by the year of 2020. Facing the challenge of big gap between increasing traffic growth and saturation of user’s charge (operator revenue), WiFi offloading is widely used by operators now.  Recently, 3GPP starts the discussion of Relese12, and small cell and heterogeneous network are expected as a potential solution to achieve both capacity increase and cost reduction. In this industry panel, we invited experts from operators, NW and terminal vendors to discuss the current status and necessary technologies towards WiFi enhancement, future small cell and heterogeneous networks.

In recent years the rapidly growing smart-phone and tablet-computer population resulted in substantial tele-traffic growth. It is anticipated that this trend will continue throughout this decade until 2020, since wireless data-communications has become the fabric of wealth-creation. Its fiscal value is estimated by economists on the basis of predicting, how much the economy as a whole would stand to lose in the absence for mobile communications. Given the current level of growth, the data-traffic carried by the mobile network in 2020 might be 1000 times higher than that in 2010. As a further challenge, the bandwidth-efficiency can only be improved at the
cost of reduced power-efficiency and vice versa...
Casting our eyes back by three decades, since the conception of the second-generation Pan-European GSM system known as the Global System of Mobile Communications in excess of three orders of magnitude bit rate improvements were achieved. This impressive development corresponds to more than an order of magnitude throughput improvement for each of the past three decades, because GSM had a data rate of 9.6 Kbps, while the High-Speed Packet Access (HSPA) system is capable of communicating at 13.7 Mbps.Without the dramatic advances in both signal processing and the achievable signal processing speed this dramatic performance improvement would have been impossible to achieve. It is important to note however that if the energy required for the transmission of a single bit is assumed to be fixed, then the above-mentioned throughput improvement would require a 1000-fold transmit power increase, which is clearly unrealistic.
Thanks to the advances of science and technology, fortunately the bit-energy required for high integrity communications has been substantially reduced, but clearly not by a factor of 1000. In
other words, the possible transmit power reductions remained more limited, even when using the most advanced multi-stage iterative receivers - the required received signal power has not been reduced by as much as a factor of 1000 or 30 dB.
This plausible observation motivates the further research of advanced wireless access.

Traffic in cellular communications systems is expected to increase by some 3 orders of magnitude within the next decade, due mainly to the rapidly growing penetration of devices with high-resolution displays and built-in cameras, such as smartphones and tablets. These tempt users to access graphics-heavy content on the Internet, and also to upload graphics-heavy content to the Internet. Growth at this rate cannot be sustained using the cellular architecture that we have depended on to date, in which geographical areas are carved up into non-overlapping cells, each served by only one base station that is connected to the backbone network through high-speed radio or optical backhaul links. Ideas for new network architectures that may provide the necessary higher data throughput have been raised recently – these include cloud RAN (radio access network), small cells such as femto-cells and pico-cells, and cooperative multi-point (CoMP) transmission.
While traffic growth drives the search for new ideas to support the increased throughput anticipated, it is equally clear that any new system architecture must be more energy efficient than current systems. After all, increasing the energy consumption of a cellular system by 3 orders of magnitude would create an unacceptable increase in energy consumption by wireless service providers, leading to higher user charges and reduced profit margins, besides being out of step with the heightened environmental awareness of the 21st century.
IEEE WCNC is the premier international forum for wireless communication researchers, and is therefore the ideal venue for a discussion of the key technical challenges facing cellular networks of the future. This proposed panel is organized by the newly created Special Interest Group on Green Cellular Networks (SIGGCN), which has attracted members from all around the globe (see Questions to be examined will include:
  • How important is energy efficiency relative to bandwidth efficiency?
  • Does the freeing up of TV bands provide sufficient capacity to satisfy most future needs?
  • How should renewable energy be incorporated into cellular networks?
  • Is it more “green” to perform joint processing in the cloud i.e. cloud-RAN, or distributed processing at base stations?
  • Do small cells in a heterogeneous network operate at a higher energy efficiency than micro-cells in a flat network architecture? 
Given the open nature of these questions, we can look forward to the most interesting debate that will make a positive and deep impression on the audience.
