The problem of providing acceptable quality-of-service (QoS) to users will become a central problem in future wireless network design. In addition to the desperate shortage of wireless spectrum, a wireless communications channel distorts transmitted signals in a way that can vary with time and system conditions. Still worse, wireless links share the available wireless channel, which makes each link prone to interference from other links. As a consequence, the capacity of a wireless link exhibits an ephemeral and dynamic nature, depending on both wireless channel conditions and transmit powers of all interfering links. At the same time, future generations of wireless networks will have to support a wide range of applications, where the number of transmission links with high QoS requirements (in terms of data rate, delay and/or bit loss) is expected to surpass traditional voice connections. This tutorial gives a compact overview of important theoretical results from network information theory, MIMO signal processing, network stability theory, power control theory, and some other related research fields. In this tutorial participants will learn how to properly assess and use these results when developing practical medium access control (MAC) strategies for different air interfaces including MIMO, CDMA and OFDMA. The tutorial will help participants better understand important theoretical concepts and their impact on practical network design.
