摘要
调度是LTE(长期演进)系统中基站为用户分配资源的重要环节和关键技术。UE(用户终端)一般通过BSR(缓存状态报告)和SR(调度请求)获得无线资源。文章针对BSR和SR同时存在时造成资源浪费的问题,通过不同的参数设置设计了解决方案,并且提出了一种在半静态调度下判断触发BSR和SR的方法以及解决填充BSR和其他BSR冲突的方法,有效地提高了资源利用率和系统稳定性。
Scheduling is an important link and key technology for resource assignment by basic stations to users in Long Term Evolution (LTE) systems. The User Equipment (UE) usually obtains radio resource by delivering Buffer Status Report (BSR) and Schedule Request (SR). As the simultaneous existence of BSR and SR results in the waste of the resources, this paper de-signs a solution on the basis of different parameters and presents an approach for triggering BSR and SR in Semi-Persistent Scheduling (SPS) and removing the conflicts between the padding BSR and other BSRs, effectively improving the resource utili-zation efficiency and system stability.
