OFDMA无线协同网络中混合业务的资源调度
Resource Allocation for Heterogeneous Services in OFDMA Systems
本文主要研究了OFDMA无线协同网络中混合业务传输的资源调度分配问题。其中混合业务包括硬服务质量(Hard Quality of Service,硬QoS)业务、尽力而为(Best Effort)业务,软服务质量(Soft Quality of Service,软QoS)业务。由于业务的效用可以比服务比特速率更能反映用户对于所请求业务的满意程度,我们利用效用来衡量资源调度策略的优劣,即满足业务的服务质量需求的前提下,尽量提高各类业务用户的总效用。我们首先分析了上述各类业务的效用和硬中断特征,然后引入软中断的概念来进一步提升软QoS业务用户的性能;随后,我们提出两种资源分配方案,硬中断分配方案与软中断分配方案,对应于上述中的硬中断和软中断。仿真结果表明,上述两种分配方案可以有效提升各业务用户的总效用性能。
his paper mainly investigates the problem of radio resource allocation for heterogeneous services transmission in OFDMA wireless networks, where the Soft QoS traffic is involved. As utility is a good scaler of the satisfaction of service, our objective is to improve the total utility of the system users, and guarantee their quality of service(QoS). Three types of services are involved, including the Hard QoS (HQ), the Best Effort (BE) and the soft QoS (SQ) traffic. At first, we analyze the utility and hard outage characteristics of the service types, and then introduce a new concept, i.e. soft outage to improve the SQ users\
