Title
(EN) Downlink transmission coordinated scheduling
(ZH) 下行链路传输协调调度
Abstract
(EN)
The present disclosure relates to a method of coordinated scheduling of a downlink transmission flow from a first radio network node (such as a radio network controller RNC) to a user equipment UE in a second radio network node (such as a Node B, an eNode B, a base station BS), the method comprising a step of : scheduling the downlink transmission flow so that the in-sequence delivery of the received data blocks can be kept in an acceptable level in the UE by adjusting a scheduling priority of the downlink transmission flow in the second radio network node. The method may further comprise steps of: estimating one or more buffer-related parameters based on buffered data for the downlink transmission flow from the first radio network node; and determining, based on the estimated one or more buffer-related parameter and/or one or more parameters associated with the operation status of the second radio network node, if the in-sequence delivery of the received data blocks to higher layers can be in an acceptable level in the UE.

本公开涉及一种在第二无线电网络节点(诸如节点B、eNodeB、基站BS)中协调调度从第一无线电网络节点(例如无线电网络控制器RNC)到用户设备UE的下行链路传输流的方法,该方法包括下列步骤:通过在第二无线电网络节点中调整下行链路传输流的调度优先级来调度下行链路传输流,使得所接收数据块的按序传递能够在UE中保持在可接受等级。该方法还可包括下列步骤:基于来自第一无线电网络节点的下行链路传输流的所缓冲数据来估计一个或多个缓冲器相关参数;以及基于所估计的一个或多个缓冲器相关参数和/或与第二无线电网络节点的操作状态关联的一个或多个参数来确定所接收数据块向更高层的按序传递是否能够在UE中处于可接受等级。
