Delay Weighted Dynamic Subcarrier Allocation Algorithm for OFDMA Downlink

XU Guo-xin,ZHANG Jian-hua,LUO Qiang,ZHANG Ping(School of Telecommunication Engineering,Beijing University of Posts and Telecommunications,Beijing 100876,China)  
The dynamic subcarrier allocation algorithm was studied.A novel algorithm for subcarrier allocation called delay weighted dynamic subcarrier assignment(DWDSA) was proposed.DWDSA was composed of inner and outer loop control structure.The function of inner loop was to allocate the subcarrier with the given power allocation scheme.And that of out loop was to adjust the delay weighted parameters.The performance of the queuing delay and buffer occupancy are improved according the simulation results.Moreover,in this algorithm the queuing delay and channel condition were consi-(dered) to improve the resources utility and to satisfy the requirement of quality of service(QoS).
