The article provides information on the activities and achievements of the 2007 IEEE Wireless Communications and Networking Conference (WCNC) held from March 11 to 15, 2007 in Hong Kong, China. The theme of the conference was Wireless Gateway, given Hong Kong's special position within the fast growing vibrant economies and excitement of China and Asia. Hong Kong is well known for its advances in information and communications technology. Furthermore, WCNC 2007 was a resounding success. It broke every record there was to be broken. It had an overwhelming number of paper submissions, truly exceeding all expectations.

When research on beyond third generation (B3G) mobile communications had just stepped into its startup period, a project called Future Technologies for a Universal Radio Environment (FuTURE) was launched in China. The goal of the project is to support theoretical research and applicable evaluation of the pro- posed technologies for B30 mobile communications. In this article the application requirements, technological challenges, and some potential solutions of B3G are discussed, and some key technologies employed in the FuTURE demonstration system are introduced.

In future public mobile access with high data rates, one of the main challenges we face is spectral efficiency. In this article we will focus on the following new spectrally efficient downlink multiple access techniques that may be essential parts of China's Beyond 3G system development: dynamic code-division multiplexing, an adaptive multi-input multi-output technique in distributed wireless communications systems, and interleaver pattern division multi-access.
