首先对以下内容进行介绍:
扩展现实(eXtened Reality,XR)和云游戏(Cloud Game,CG)作为最重要的5G媒体应用之一,具有低时延、高吞吐量和高可靠性的要求,要求短时间内进行较大数据的传输,这意味着在短时间内其突发吞吐量可能远高于平均吞吐量。例如,平均吞吐量为100Mbps的XR业务在短测量窗口上的突发吞吐量可达300Mbps,且同时还需保证高可靠性。XR是不同类型的现实的总称,指的是由计算机技术和设备产生的所有真实和虚拟相结合的环境和人机交互。它包括增强现实(Augmented Reality,AR)、混合现实(Mixed Reality,MR)和虚拟现实(Virtual Reality,VR)等代表形式。
图1是相关技术提供的XR业务按照数据帧的建模示意图,图2是相关技术提供的扩展现实(eXtened Reality,XR)业务帧和分组数据单元(Packet Data Unit,PDU)(用于指示高层业务数据包)的关系的示意图,如图1和图2所示,每个数据帧对应一个XR视频帧,同一视频帧可分割为多个分组数据PDU。
XR业务中,业务特性要求是针对数据帧的,例如针对场景、视频混合流,业务特性需求为:周期60fps(frame per second,帧每秒);数据速率10Mbps/20Mbps;分组时延预算可以包括分组时延预算(packet delay budget,PDB)30ms,还可以包括10/15/60ms。
XR业务具有三个特性:周期性;数据帧很大且单个帧大小变化很大;帧到达时间具有不可预期的抖动(jitter)。
图3是相关技术提供的上行预配置资源的示意图,如图3所示,在通信系统中,对于时延要求高的周期性业务采用半持续调度。基站按照业务周期 和业务数据包大小为终端预配置周期性资源,上行预配置资源称为预配置资源(configured grant,CG),在一个周期内,可以连续分配多个上行资源。半持续调度机制对于语音(VoIP)等数据包大小固定的业务很适用,但对于XR业务这种周期性到达的数据帧变化很大的业务,如果预配置资源分配过多,会造成资源浪费;如果预配置资源少于当前到达帧的数据量,终端只能等待基站分配动态调度资源,但基站在不确定终端数据量时,是不会分配动态调度资源的。
相关技术中有上行缓存上报机制,当基站接收到终端上报的BSR,可以根据终端的BSR上报,分配相应大小的上行资源。现有BSR有三种类型:regular BSR、periodic BSR和padding BSR。
相关技术中BSR的触发机制如下:
常规BSR(Regular BSR):(1)当有比当前buffer中的数据更高优先级的数据到达或原本为空的buffer中有数据到达时触发;(2)retxBSR-Timer超时且缓存中有数据时触发。
周期性BSR(Periodic BSR):periodicBSR-Timer超时时触发Periodic BSR。
捎带BSR(Padding BSR):如果UE在组织媒体接入控制(Medium Access Control,MAC)PDU的时候,上行授权(grant)中除了需要传输的数据外还可以容纳有资源可用更多比特位(Padding),可以触发Padding BSR。
显然,XR分组数据发送过程中不会触发BSR。
本公开实施例提供了BSR触发和上报方法及装置,用以保障数据传输的可靠性,节省资源。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。

具体来说,终端为了保证数据的传输,可以在上行传输资源不够导致待发送的PDU集中部分PDU暂时无法传输时,向网络侧设备发送BSR,向网络侧设备上报还未传输的剩余数据量,以使网络侧设备在获取剩余数据量后,可以及时为终端分配上行传输资源,以保证暂时无法传输的部分PDU可以及时传输,增加数据传输的可靠性,减小时延,且也不需要为了适配偶尔的较大数据而分配过多资源,可以有效节省资源。
可选地,包含PDU集中未传输的剩余数据量的BSR还可以称为PDU set BSR。
