    • Uplink transmission scheduling requests (SRs) may be prohibited for a lower priority data flow, logical channel group (e.g., VoIP configured with semi-persistent resource allocation), or other grouping but may still be triggered for higher priority traffic (e.g., data connected to a signaling radio bearer (SRB)). More efficient scheduling is also achieved by allowing an uplink transmission scheduler to distinguish between different priority flows or groups (e.g., LCGs) without a buffer status report (BSR), As a result, when a semi-persistent resource is scheduled for the lower priority data, there is less delay for high priority data while eliminating uplink and downlink control signaling, i.e., fewer scheduling requests (SRs) and uplink grants, for the lower priority data.
    • 对于较低优先级的数据流,逻辑信道组(例如,配置有半持久资源分配的VoIP)或其他分组,上行链路传输调度请求(SR)可能被禁止,但是对于较高优先级的业务(例如,数据连接 到信令无线电承载(SRB))。 通过允许上行链路传输调度器在没有缓冲器状态报告(BSR)的情况下区分不同的优先权流或组(例如,LCG)也可实现更有效的调度。结果,当半持久资源被调度为较低优先级时 数据,高优先级数据的延迟较少,同时消除了较低优先级数据的上行链路和下行链路控制信令,即更少的调度请求(SR)和上行链路授权。
