Description

一种缓冲区状态上报BSR触发方法及装置
本申请要求在2014年3月31日提交中国专利局、申请号为201410125864.6、发明名称为“一种缓冲区状态上报BSR触发方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及无线通信领域,尤其涉及一种缓冲区状态上报BSR触发方法及装置。
背景技术
在未来移动通信系统发展中,为了更好的满足用户需求、提升设备之间信息交互的效率,引入了设备到设备发现(Device to Device Discovery,D2D Discovery)以及设备到设备通信(Device to Device Communication,D2D Communication)的机制。
在长期演进(Long Term Evolution,LTE)系统中,通信采取的是网络集中控制的方式,即设备到网络(Device to Network,D2N)传输方式,图1示出了D2N传输方式的系统架构图。如图1所示,用户设备(User’s Equipment,UE,即终端)的上下行数据都是在演进节点B(evolve NodeB,eNodeB,即基站)的控制下进行发送和接收的,UE和UE之间的通信是由eNodeB进行转发和控制的,因此,UE和UE之间不存在直接的通信链路。
在LTE Rel-11之前版本中,D2N系统架构下的缓冲区状态上报(Buffer State Reporting,BSR)触发机制分为:常规BSR(Regular BSR)、周期性BSR(Periodic BSR)和捎带BSR(Padding BSR)。
基站在给UE分配上行资源后,如果该上行资源的大小恰好足够用于传输上行数据,则不触发BSR,UE利用该上行资源发送上行数据;如果该上行资源不够发送所有的上行数据,则优先上报Regular BSR或者Periodic BSR,基 站再根据BSR中携带的UE所需上行数据量进行后续传输调度。UE在组织媒体接入控制(Media Access Control,MAC)协议数据单元(Protocol Data Unit,PDU)时,一个MAC PDU中最多包含一个BSR,如果多个BSR同时触发,则只上报优先级最高的BSR,其中,Regular BSR的优先级=Periodic BSR的优先级>Padding BSR的优先级。
在LTE系统中,相互靠近的设备和设备之间允许直接进行D2D Communication传输,图2示出了D2D传输方式的系统架构图。如图2所示,UE与UE之间的通信链路为设备到设备链路(Device to Device Link,D2D Link),UE与eNodeB之间的蜂窝通信链路为设备到网络蜂窝链路(Device to Network Link,D2N Link)。D2D Communication的资源分配方式为:由基站分配用于承载D2D Communication调度信令的资源和用于承载D2D Communication数据的资源。因此,UE需要通过D2N蜂窝链路向eNodeB请求用于D2D的传输资源,D2D资源请求过程通过D2N BSR过程实现,且D2D资源请求过程独立于D2N BSR过程。
D2D BSR的触发机制包括:D2D Regular BSR、D2D Periodic BSR和D2D Padding BSR。对于D2D Regular BSR和D2D Periodic BSR,其触发机制可以沿用D2N Regular BSR和D2N Periodic BSR的触发机制,但是对于D2D Padding BSR,其触发机制不同于D2N Padding BSR,需要引入新的触发机制。

除用于承载D2N Padding BSR以外的其他D2N MAC CE占用的资源,其中,D2N MAC CE占用的资源包括MAC子头和净荷所占用的资源;以及,
除UL-CCCH以外,D2N链路上的逻辑信道数据占用的资源,其中,D2N链路上的逻辑信道数据占用的资源包括MAC子头和净荷占用的资源;以及,
除用于承载D2D Padding BSR以外的其他D2D MAC CE占用的资源,其中,D2D MAC CE占用的资源包括MAC子头和净荷占用的资源。
进一步地,从用户设备在D2N MAC PDU所在子帧的上行资源中按照如下第一优先级顺序或第二优先级顺序减去以下资源,得到所述Padding资源大小。
第一优先级顺序中按照优先级从高到低包括:除用于承载D2N Padding BSR以外的其他D2N MAC CE占用的资源,除UL-CCCH以外D2N链路上的逻辑信道数据占用的资源,除用于承载D2D Padding BSR以外的其他D2D MAC CE占用的资源。
第二优先级顺序中按照优先级从高到低的顺序包括:除用于承载D2N Padding BSR以外的其他D2N MAC CE占用的资源,除用于承载D2D Padding BSR以外的其他D2D MAC CE占用的资源,除UL-CCCH以外D2N链路上的逻辑信道数据占用的资源。
具体实施时,若基站在上行子帧内为该用户设备分配的资源大小大于该用户设备在该子帧上需要传输的D2N数据(包括对应的MAC子头和净荷)和控制信息(D2N Padding BSR除外)占用的资源大小,则该用户设备此时确定存在Padding资源,且Padding资源大小为基站在该子帧分配的上行资源减去除用于承载D2N Padding BSR以外的其他D2N MAC CE占用的资源、除UL-CCCH以外,D2N链路上的逻辑信道数据占用的资源、以及除用于承载D2D Padding BSR以外的其他D2D MAC CE占用的资源以外的剩余资源。
步骤32:用户设备根据Padding资源大小,以及D2D Padding BSR MAC CE的优先级,对是否触发D2D Padding BSR进行判决。其中,D2D Padding BSR MAC CE为用于承载设备到设备通信的捎带缓冲区状态上报的媒体接入控制层控制单元,D2D Padding BSR为设备到设备通信的捎带缓冲区状态上报,D2N Padding BSR为设备到网络链路的捎带缓冲区状态上报。
优选地,在D2D Padding BSR MAC CE的优先级低于D2N Padding BSR MAC CE的优先级的情况下,若通过上述步骤31确定得到的Padding资源足够承载D2D Padding BSR与D2N Padding BSR,则确定触发D2D Padding BSR和D2N Padding BSR;若通过上述步骤31确定得到的Padding资源在承载D2N  Padding BSR后的剩余资源不够承载D2D Padding BSR,则确定触发D2N Padding BSR但不触发D2N Padding BSR。
举例来说,如图4所示,如果Padding资源只能足够承载D2N Padding BSR(包括MAC子头和净荷),则确定触发D2N Padding BSR,不会触发D2D Padding BSR。如图5所示,如果Padding资源足够同时承载D2D Padding BSR(包括MAC子头和净荷)和D2N Padding BSR(包括MAC子头和净荷),则确定同时触发D2D Padding BSR和D2N Padding BSR。
在D2D Padding BSR MAC CE的优先级高于D2N Padding BSR MAC CE的优先级的情况下,若通过上述步骤31确定得到的Padding资源足够承载D2D Padding BSR(包括MAC子头和净荷),则确定触发D2D Padding BSR。
进一步地,若通过上述步骤31确定得到的Padding资源在承载D2D Padding BSR后的剩余资源不够承载D2N Padding BSR,则确定触发D2D Padding BSR但不触发D2N Padding BSR;若通过上述步骤31确定得到的Padding资源足够承载D2D Padding BSR(包括MAC子头和净荷)和D2N Padding BSR(包括MAC子头和净荷),则确定触发D2D Padding BSR和D2N Padding BSR。
举例来说,在D2D Padding BSR MAC CE的优先级高于D2N Padding BSR MAC CE的优先级的情况下,如图6所示,如果Padding资源只能足够承载D2D Padding BSR(包括MAC子头和净荷),则确定触发D2D Padding BSR,不会触发D2N Padding BSR。如图7所示,如果Padding资源足够同时承载D2D Padding BSR(包括MAC子头和净荷)和D2N Padding BSR(包括MAC子头和净荷),则确定同时触发D2D Padding BSR和D2N Padding BSR。
在步骤32之后,用户设备需要将上行数据组织成MAC PDU,并递交MAC层以下的协议层进行传输。用户设备在组织MAC PDU时,D2N MAC PDU中包含的MAC CE对应的MAC子头均放置在包含的数据单元对应的MAC子头之前;D2N MAC PDU中,MAC CE和数据单元在MAC PDU净荷中的放置顺序与对应的MAC子头的放置顺序相匹配。
比如,以MAC PDU子头包含除用于承载D2N Padding BSR以外的其他D2N MAC CE占用的资源、除用于承载D2D Padding BSR以外的其他D2D MAC CE占用的资源、D2N Padding BSR MAC CE、D2D Padding BSR MAC CE以及D2N数据对应的MAC子头为例,MAC子头的一种可能的格式可以如图8所示,其中,按照如下顺序进行放置:除用于承载D2N Padding BSR以外的其他D2N MAC CE子头、除用于承载D2D Padding BSR以外的其他D2DMAC CE子头、D2N Padding BSR MAC CE子头、D2D Padding BSR MAC CE子头、D2N数据对应的MAC子头。
本发明的上述实施例中,用户设备组织D2N MAC PDU时确定Padding资源大小,并根据Padding资源大小、D2D Padding BSR MAC CE的优先级,对是否触发D2D Padding BSR进行判决,实现了D2D Padding BSR触发机制。

优选地,所述判决单元92具体用于,若所述Padding资源在承载D2D Padding BSR后的剩余资源不够承载D2N Padding BSR,则确定触发D2D Padding BSR但不触发D2N Padding BSR;若所述Padding资源足够承载D2D Padding BSR和D2N Padding BSR,则确定触发D2D Padding BSR和D2N Padding BSR。
优选地,所述确定单元91具体用于,从所述用户设备在所述D2N MAC PDU所在子帧的上行资源中减去以下资源,得到所述Padding资源大小:除用于承载D2N Padding BSR以外的其他D2N MAC CE占用的资源,所述占用的资源包括MAC子头和净荷所占用的资源;以及,除上行公共控制信道UL-CCCH以外,D2N链路上的逻辑信道数据占用的资源,所述占用的资源包括MAC子头和净荷占用的资源;以及,除用于承载D2D Padding BSR以外的其他D2D MAC CE占用的资源,所述占用的资源包括MAC子头和净荷占用的资源。
