Abstract
This paper considers localized packet assignments and distributed packet assignments as joined in the transmission time interval (TTI) for downlink in multi-user OFDM systems. To enhance throughput, we propose an adaptive packet assignment using mode selection between the localized packet assignment and the distributed packet assignment. Moreover, we compare three types of localized packet assignment schemes and show the performance of GPA approaches to optimum performance by improving the spectral efficiency.
