简介: |
Over the past decade, wireless communications has seen an exponential growth and will certainly continue to witness spectacular developments due to the emergence of new interactive multimedia applications and highly integrated systems driven by the rapid growth in information services and microelectronic devices. To support such applications under limited radio resources and harsh wireless channel conditions, dynamic resource allocation, which achieves both higher system spectral efficiency and better Quality of Service (QoS), has been identified as one of the key and promising techniques. In particular, jointly optimizing resource allocation across adjacent and even non-adjacent layers of the protocol stack leads to a dramatic improvement in the overall system performance. In this talk, we will discuss the challenges facing the next-Gen ubiquitous broadband systems. In particular, we shall provide an overview of recent research on dynamic resource allocation, especially for MIMO and OFDM systems. Open issues on cross-layer design, dynamic resource allocation, and adaptation techniques for increasing system capacity and spectral efficiency while meeting the stringent requirements of future networks will also be discussed. |
