Resource allocation and scheduling for real-time traffic in OFDMA
Author(s): 
Pages: 1353-1358
Year: Issue:  12
Journal: Journal of University of Science and Technology of China

Keyword:  正交频分复用接入分组调度子载波分配实时业务;
Abstract: 提出了一种适合于OFDMA系统中实时业务传输的资源分配与调度算法,该算法利用物理层的信道信息和MAC层的业务信息,采取分组调度与子载波分配交替进行的资源分配方式,在满足数据包传输时延要求的同时,最大化系统的吞吐量.仿真结果表明,该算法无论是在系统的吞吐量、丢包率,还是数据包等待时延方面,都具有良好的性能.
