As the high speed bandwidth demand grows, 4G wireless networks are also emerging. This talk will briefly review the vision of 4G networks which are expected to be based on MIMO/OFDMA and all-IP technologies. Then I will present the research results for cross layer design issues. Especially, cross layer scheduling and channel feedback and random access techniques that have been researched recently from Network Laboratory at Seoul National University will be covered.
