Abstract EN
This paper aims at the frequency-domain packet scheduling (FDPS) problem in orthogonal frequency division multiple access (OFDMA) system.
Under users’ data queue size constraints, a new swap-based FDPS algorithm is proposed to achieve further improvement in system throughput.
In this algorithm, the swap of physical resource blocks (PRBs) between different users is introduced to give a comprehensive view of the overall scheduling process.
Moreover, the proposed algorithm optimizes the choosing method of swap candidates and always tries to select the user who can maximize the throughput improvement.
Simulation results demonstrate that this new algorithm can improve the system throughput significantly as well as reduce the resource waste effectively.
