Description

BSR触发方法及装置、存储介质、用户设备
本申请要求于2019年1月31日提交中国专利局、申请号为201910098408.X、发明名称为“BSR触发方法及装置、存储介质、用户设备”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
本发明涉及通信技术领域，尤其涉及一种BSR触发方法及装置、存储介质、用户设备。
背景技术
一个时延敏感网络(Time-Sensitive Networking,TSN)数据流(flow)中的数据包到达时间具有固定的时间偏移量(offset)以及周期。预配置授权(Configured grant)可以用来支持确定性的周期业务。RAN1#95会议已经同意，支持在一个服务小区(serving cell)上的一个给定的带宽部分(Band Width Part,BWP)上配置并激活多套预配置授权的资源配置(configurations of configured grant)，用以支持多种不同的services/traffic types(具有不同特性的多个工业/TSN流multiple Industrial/TSN streams with different characteristic)，也可以用以增强传输的可靠性减小传输时延。
另外，用户设备(User Equipment,UE)或者核心网可以将上行TSN flow的一些业务传输模式(traffic pattern)相关信息通知给基站，有助于基站准确地为UE配置上行预配置(configured)/半静态调度(Semi-Persistent Scheduling,SPS)资源。
每一个逻辑信道(Logical Channel,LCH)都可能会被配置到一个 逻辑信道组(Logical Channel Group,LCG)中，通过IE LogicalChannelConfig中的logicalChannelGroup字段来配置，此字段为可选字段(optional)，若该字段存在，那么该LCH就被配置到了所指示的LCG中，反之，该LCH就没有被配置到任何LCG。当前协议中，LCG的最大个数为8个。媒体接入控制(Media Access Control,MAC)实体会基于TSs 38.322和38.323中的数据量计算步骤确定一个LCH的上行待传输数据的数据量，缓冲状态报告(Buffer State Report,BSR)上报时，以LCG为单位对上行待传输数据量进行上报，一个LCG的待传输数据量为该LCG所包含的各个LCH的待传输数据量的总和。
下述任意一项事件发生，都会触发一个BSR:MAC实体中，属于某一LCG的一个LCH有上行新数据到达；并且所述到达的上行新数据属于一个LCH，且该LCH的优先级高于任意一个属于某一LCG且存在上行待传输数据的LCH的优先级；或者配置了LCG的所有LCHs都没有上行待传输数据。这种情况下触发(trigger)的BSR叫做'常规(Regular)BSR'；上行资源被分配且剩余位元(padding bits)的大小大于或等于BSR MAC CE和它的子头的大小，这种情况要trigger BSR，且这种情况下trigger的BSR叫做'位元(Padding)BSR'；BSR重传定时器(retxBSR-Timer)超时，并且至少有一个配置了LCG的LCH有上行待传输数据，这种情况要trigger BSR，且这种情况下trigger的BSR叫做'Regular BSR'；BSR周期上报定时器(periodicBSR-Timer)超时，这种情况要trigger BSR，且这种情况下trigger的BSR叫做'周期(Periodic)BSR'。
上述周期性业务中某些数据流可能会有抖动，也就是说，一次到达的数据量超过了或小于所述固定大小，或者数据到达的时间点与固定offset和周期所确定的该flow数据到达的固定时间点有所偏差。
但是，通过现有技术，若将该flow所对应的LCH配置到某个LCG中，那么该flow所对应的LCH就需要根据现有的BSR trigger 条件在每次到达新数据时就去判断是否要触发BSR以将待传输数据量告知基站，并且由其他条件满足所trigger的BSR在上报时也要包含该LCH的待传输数据量，若基站已经知道了该flow的traffic pattern相关信息，那么BSR的上报是不需要的，也就会造成上行资源的浪费。若不为该flow所对应的LCH配置任何LCG，那么该flow所对应的LCH就不会根据现有的BSR trigger条件在每次到达新数据时就去判断是否要触发BSR以将待传输数据量告知基站，并且由其他条件满足所trigger的BSR在上报时也不会包含该LCH的待传输数据量，那么在flow发生抖动时，也不会上报BSR，导致一部分基站未知的数据量不能及时通知给基站，进而导致基站不能及时地为UE分配资源，造成数据不能及时传输，对于一些对传输时延要求较高的业务来说，可能无法满足其时延需求，降低通信质量。

具体实施方式
如背景技术中所述，若将该flow所对应的LCH配置到某个LCG中，那么该flow所对应的LCH就需要根据现有的BSR trigger条件在每次到达新数据时就去判断是否要触发BSR以将待传输数据量告知基站，并且由其他条件满足所trigger的BSR在上报时也要包含该LCH的待传输数据量，若基站已经知道了该flow的traffic pattern相关信息，那么BSR的上报是不需要的，也就会造成上行资源的浪费。若不为该flow所对应的LCH配置任何LCG，那么该flow所对应的LCH就不会根据现有的BSR trigger条件在每次到达新数据时就去判断是否要触发BSR以将待传输数据量告知基站，并且由其他条件满足所trigger的BSR在上报时也不会包含该LCH的待传输数据量，那么在flow发生抖动时，也不会上报BSR，导致一部分基站未知的数据量不能及时通知给基站，进而导致数据不能及时传输，对于一些对传输时延要求较高的业务来说，可能无法满足其时延需求，降低通信质量。
具体地，本申请发明人发现，对于某个LCH不触发BSR且该LCH的待传输数据量不上报给网络，现有技术是通过如下方式实现的：通过不为某个LCH配置任何LCG来实现；
-该LCH没有BSR trigger功能；
-并且当其他某个LCH有新数据到达并将自己的优先级与其他所有配置了LCG且有待传输数据的LCHs的优先级进行比较以判断自己是否触发BSR时，忽略该LCH；
-并且由于BSR是以LCG为单位上报的，该LCH不属于任何LCG，那么该LCH的待传输数据量也不会上报给网络。
-并且当BSR重传定时器(retxBSR-Timer)超时，检查是否至少有一个配置了LCG的LCH有上行待传输数据以判断这种情况是否要trigger BSR时，忽略该LCH。
也就是说，通过现有技术，只能实现某个LCH一直具有BSR触发功能或者一直不具有BSR触发功能。
本申请发明人还发现，对于既具有周期性又具有抖动特性的数据流：对于周期性来说，若UE或者核心网将一些traffic pattern相关信息(如固定偏移量、周期、数据包大小)通知给了基站，那么基站就知道了在所述固定偏移量和周期所确定的的固定时间点会有所述固定大小的数据量到达，那么该flow所对应的LCH就不需要根据现有的BSR trigger条件在每次到达新数据时就去判断是否要触发BSR以将待传输数据量告知基站，并且由其他条件满足所触发的BSR在上报时不需要包含该LCH的待传输数据量；对于抖动性来说，如果一次到达的数据量超过所述固定大小的量大于预定的阈值时，或者数据到达的时间点与固定偏移量和周期所确定的该flow数据到达的固定时间点的偏差大于预定的阈值时，需要上报该LCH的待传输数据量。
本发明技术方案中，对于既具有周期性又具有抖动特性的上行数据，只有在抖动发生(也即一次性到达的上行数据的数据量超过所述 固定值的部分的大小达到第一预设门限，或者上行数据到达的时间点与位于所述到达的时间点之后下一个周期时间点的时间差达到第二预设门限)时，才会触发第一BSR，避免了在抖动未发生时占用上行资源发送没有必要的BSR导致上行资源的浪费；通过第一BSR将上行数据的数据量进行上报，以使得基站能够获取到抖动发生时产生的基站未知数据量，进而能够为该上行数据配置相应的上行资源，保证上行数据的及时有效传输，减小数据传输时延。
为使本发明的上述目的、特征和优点能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。
图1是本发明实施例一种BSR触发方法的流程图。
图1所示BSR触发方法可以包括以下步骤：
步骤S101：确定MAC实体中一次性到达的上行数据，所述上行数据对应逻辑信道，且所述逻辑信道隶属于逻辑信道组；
步骤S102：确定所述周期性业务中每次到达的数据量对应的固定值，以及所述逻辑信道所承载的业务的传输周期和时间偏移量；
步骤S103：如果所述上行数据的数据量超过所述固定值的部分的大小达到第一预设门限，或者，根据所述传输周期和所述时间偏移量确定各个周期时间点，如果所述上行数据到达的时间点与位于所述到达的时间点之后下一个周期时间点的时间差达到第二预设门限，则触发第一BSR，所述第一BSR包括所述上行数据的数据量。
需要指出的是，本实施例中各个步骤的序号并不代表对各个步骤的执行顺序的限定。
在步骤S101的具体实施中，在MAC实体中，属于某一逻辑信道组的逻辑信道有上行数据到达，该上行数据为新的待传输数据。具体地，该逻辑信道属于逻辑信道组，也就是说，该逻辑信道被配置到了上述逻辑信道组，逻辑信道组的具体信息本发明实施例对此不作限制。
具体地，MAC实体中一次性到达的上行数据可以是指在同一时刻或者一定时间范围内到达MAC实体的所有上行数据。
具体实现中，可以通过IE LogicalChannelConfig中的logicalChannelGroup字段来配置，若该字段存在，那么该LCH就被配置到了所指示的LCG中，反之，该LCH就没有被配置到任何LCG。
在步骤S102的具体实施中，如果逻辑信道所承载的业务属于周期性业务，则可以确定所述周期性业务中每次到达的数据量对应的固定值，以及所述逻辑信道所承载的业务的传输周期和时间偏移量。其中，根据传输周期和所述时间偏移量可以确定各个周期时间点。
具体地，数据量对应的固定值表示周期性业务中每次应到达的数据量大小，时间偏移量表示数据到达(例如，可以为第一次数据到达)的时间点与参考时间的偏移量，参考时间例如可以是系统帧0的子帧0，也可以是其他任意可实施的时间位置，本发明实施例对此不作限制。
关于周期性业务，请参照图2。数据流flow1和数据流flow2均属于周期性业务。其中，数据流flow1具有时间偏移量offset1、周期T1以及固定值S1(图中未标示)。数据流flow2具有时间偏移量offset2、周期T2以及固定值S2(图中未标示)。具体地，根据时间偏移量offset1以及周期T1可以确定数据流flow1的各个周期时间点t1、t3、t5….。根据时间偏移量offset2以及周期T2可以确定数据流flow2的各个周期时间点t2、t4….。
在步骤S103的具体实施中，第一BSR的触发条件为：上行数据的数据量超过所述固定值的部分的大小达到第一预设门限，或者上行数据到达的时间点与位于所述到达的时间点之后下一个周期时间点的时间差达到第二预设门限。
需要说明的是，第一预设门限和第二预设门限可以根据实际的应用场景进行适应性的配置，本发明实施例对此不作限制。
在一个具体的例子中，请继续参照图2，对于数据流flow1的各个周期时间点t1、t3、t5，如果上行数据到达的时间点t处于t1和t3之间，则判断到达的时间点t与周期时间点t3之间的时间差是否达到第二预设门限。
本实施例中，上报给基站的第一BSR包括所述上行数据的数据量，也即包括发生抖动的逻辑信道中待传输的数据量。在一个具体的例子中，第一BSR包括所述逻辑信道隶属的逻辑信道组中各个逻辑信道的待传输数据量的总和。
本发明一个非限制性的实施例中，所述逻辑信道的业务传输模式(traffic pattern)预先发送至基站并被所述基站接收成功。
本实施例中，业务传输模式可以是由用户设备发送给基站的，业务传输模式也可以由核心网发送给基站。
逻辑信道的业务传输模式包括所述逻辑信道所承载的周期性业务中每次到达的数据量对应的固定值，以及所述逻辑信道所承载的业务的传输周期和时间偏移量。
也就是说，当基站成功获取到逻辑信道的业务传输模式相关信息(如周期、时间偏移量和固定值)之后，在该逻辑信道没有发生抖动的情况下，其业务传输模式相关信息也未发生变化，由此，该逻辑信道不需要再触发BSR。只有逻辑信道发生抖动时，将导致基站按照原有业务传输模式调度无法满足UE的时延需求，才需要触发BSR来上报准确的待传输数据量。
本发明实施例中，对于既具有周期性又具有抖动特性的上行数据，只有在抖动发生(也即上行数据的数据量超过所述固定值的部分的大小达到第一预设门限，或者上行数据到达的时间点与位于所述到达的时间点之后下一个周期时间点的时间差达到第二预设门限)时，才会触发第一BSR，避免了在抖动未发生时占用上行资源发送没有必要的BSR导致上行资源的浪费；通过第一BSR将上行数据的数据量 进行上报，以使得基站能够获取到抖动发生时产生的基站未知数据量，进而能够为该上行数据配置相应的上行资源，保证上行数据的及时有效传输，减小数据传输时延。
在本发明一个非限制性的实施例中，请参照图3，图1所示步骤S103可以包括以下步骤：
步骤S1031：接收所述逻辑信道所对应的信令；
步骤S1032：响应于所述信令中包含触发条件指示，判断所述上行数据的数据量超过所述固定值的部分的大小是否达到第一预设门限，所述触发条件指示包括所述第一预设门限；
步骤S1033：如果所述上行数据的数据量超过所述固定值的大小达到第一预设门限，则触发所述第一BSR。
具体实施中，每一逻辑信道配置有相对应的信令，可以是已有的逻辑信道配置信令，逻辑信道配置信元IE LogicalChannelConfig配置有逻辑信道的相关参数；也可以是新增的RRC信令、MAC信令、物理层信令。
逻辑信道所对应的信令可以包含条件触发指示。所述条件触发指示可以携带于新增信令中，也可以携带于已有的逻辑信道配置信令中。在一个具体的例子中，可以在已有的逻辑信道配置信令中或者新增信令中配置字段dataVolume以指示第一预设门限。
在信令中包含触发条件指示时，执行判断操作，也即判断所述上行数据的数据量超过所述固定值的部分的大小是否达到第一预设门限，以决定是否触发第一BSR。
在本发明另一个非限制性的实施例中，请参照图4，图1所示步骤S103可以包括以下步骤：
步骤S1034：接收所述逻辑信道所对应的信令；
步骤S1035：响应于所述信令中包含触发条件指示，根据所述传 输周期和所述时间偏移量确定各个周期时间点，并判断所述上行数据的到达的时间点与位于所述到达的时间点之后下一个周期时间点的时间差是否达到第二预设门限，所述触发条件指示包括所述第二预设门限；
步骤S1036：如果所述上行数据的到达的时间点与位于所述到达的时间点之后下一个周期时间点的时间差达到第二预设门限，则触发所述第一BSR。
本实施例中，逻辑信道所对应的信令可以包含条件触发指示。所述条件触发指示可以携带于新增信令中，也可以携带于已有的逻辑信道配置信令中。在一个具体的例子中，可以在已有的逻辑信道配置信令中或者新增信令中配置字段timeGap以指示第二预设门限。
与前述实施例不同的是，在信令中包含触发条件指示时，执行判断操作，也即判断所述上行数据的到达的时间点与位于所述到达的时间点之后下一个周期时间点的时间差是否达到第二预设门限，以决定是否触发第一BSR。
前述实施例中，逻辑信道所对应的信令中包含触发条件指示，这种情况下的逻辑信道所承载的业务通常属于周期性业务。下述实施例中，逻辑信道所对应的信令中未包含触发条件指示，这种情况下的逻辑信道所承载的业务通常属于非周期性业务，或者该逻辑信道所承载的业务属于周期性业务且其业务传输模式没有被基站接收成功。
在本发明一个非限制性的实施例中，请参照图5，BSR触发方法除了包括图1所示各个步骤之外，还可以包括以下步骤：
步骤S501：接收所述逻辑信道所对应的信令，所述逻辑信道所承载的业务属于周期性业务或非周期性业务；
步骤S502：响应于所述信令中未包含触发条件指示，判断所述逻辑信道的优先级是否高于隶属于逻辑信道组且有待传输数据的其他逻辑信道的优先级，所述其他逻辑信道所对应的信令中均未包含所 述触发条件指示，或者，所述其他逻辑信道的数量为多个时，部分其他逻辑信道所对应的信令中包含所述触发条件指示，剩余其他逻辑信道所对应的信令中未包含所述触发条件指示；
步骤S503：如果所述逻辑信道的优先级高于所述隶属于逻辑信道组且有待传输数据的其他逻辑信道的优先级，则触发第二BSR，所述第二BSR不包括或包括所对应的信令中包含所述触发条件指示的逻辑信道的数据量。
本实施例中，逻辑信道可以属于周期性业务，也可以属于非周期性业务。逻辑信道预先配置有优先级。
在信令中未包含触发条件指示的情况下，可以将逻辑信道的优先级与隶属于逻辑信道组且有待传输数据的其他逻辑信道的优先级进行比较。其他逻辑信道所对应的信令中可以未包含触发条件指示，也可以包含所述触发条件指示。
可以理解的是，所述其他逻辑信道的数量可以是一个或多个。所述其他逻辑信道的数量为多个时，将所述逻辑信道的优先级与多个其他逻辑信道的优先级均进行比较。
在所述逻辑信道的优先级高于所述隶属于逻辑信道组且有待传输数据的其他逻辑信道的优先级的情况下，触发第二BSR。具体地，第二BSR包括所述逻辑信道所属的逻辑信道组的待传输数据量，，也可以包含其他逻辑信道组的待传输数据量，其中每个逻辑信道组的待传输数据量为组内各个逻辑信道的待传输数据量的总和。可选地，第二BSR可以不包括所对应的信令中包含所述触发条件指示的逻辑信道的数据量，也就是说，对于每一个逻辑信道组，第二BSR包括所述逻辑信道组中除了所对应的信令中包含所述触发条件指示的逻辑信道之外，其他各个逻辑信道的待传输数据量的总和。例如，对于逻辑信道1，其属于逻辑信道组1，逻辑信道组1还包括逻辑信道2、逻辑信道3和逻辑信道4；其中，逻辑信道2所对应的信令中包含触发条件指示、逻辑信道3和逻辑信道4所对应的信令中均未包含触发 条件指示；逻辑信道1符合触发第二BSR的条件时，触发第二BSR，第二BSR可以包括逻辑信道1、逻辑信道3和逻辑信道4中待传输数据量之和。
本实施例中，对于基站没有预先配置上行资源且优先级较高的逻辑信道，可以在其满足上述条件的情况下触发第二BSR，以保证该逻辑信道中的待传输数据能够及时通过BSR上报给基站，使得基站可以及时分配上行资源，减小该逻辑信道的上行数据的传输时延。
在本发明一个非限制性的实施例中，请参照图6，BSR触发方法除了包括图1所示各个步骤之外，还可以包括以下步骤：
步骤S601：接收逻辑信道所对应的信令，所述逻辑信道所承载的业务属于周期性业务或非周期性业务；
步骤S602：响应于所述信令中未包含触发条件指示，判断隶属于逻辑信道组的其他逻辑信道是否均未有上行数据到达，所述其他逻辑信道接收到所对应的信令中均未包含所述触发条件指示，或者，所述其他逻辑信道的数量为多个时，部分其他逻辑信道所对应的信令中包含所述触发条件指示，剩余其他逻辑信道所对应的信令中未包含所述触发条件指示；
步骤S603：如果所述隶属于逻辑信道组的其他逻辑信道均未有上行数据到达，则触发第三BSR，所述第三BSR不包括或包括所对应的信令中包含所述触发条件指示的逻辑信道的数据量。
与前述实施例不同的是，本实施例可以判断所述隶属于逻辑信道组的其他逻辑信道是否均未有上行数据到达。如果是，则触发第三BSR，第三BSR可以包括所对应的信令中包含所述触发条件指示的逻辑信道的数据量，或者可以未包括所对应的信令中包含所述触发条件指示的逻辑信道的数据量。
在本发明一个非限制性的实施例中，请参照图7，BSR触发方法除了包括图1所示各个步骤之外，还可以包括以下步骤：
步骤S701：接收所有逻辑信道所对应的信令；
步骤S702：判断当前用户设备是否存在可用的上行资源并且剩余位元的大小是否达到BSR的MAC控制元素及其子头的大小；
步骤S703：如果当前用户设备存在可用的上行资源并且剩余位元的大小达到所述BSR的MAC控制元素及其子头的大小，则触发第四BSR，所述第四BSR不包括或包括所对应的信令中包含所述触发条件指示的逻辑信道的数据量。
本实施例中，其中，所述剩余位元是指当前用户设备在将上行资源分配给本次待传输的数据之后所剩余的上行资源。剩余位元的大小达到所述BSR的MAC控制元素及其子头的大小表示，剩余位元的大小足以承载所述BSR及其子头，因而可以触发第四BSR。
在本发明一个非限制性的实施例中，请参照图8，BSR触发方法除了包括图1所示各个步骤之外，还可以包括以下步骤：
步骤S801：接收所有逻辑信道所对应的信令；
步骤S802：如果BSR重传定时器超时，并且至少有一个隶属于逻辑信道组且所对应的信令中未包含所述触发条件指示的逻辑信道有待传输数据，则触发第五BSR，所述第五BSR不包括或包括所对应的信令中包含所述触发条件指示的逻辑信道的数据量。
步骤S803：如果BSR重传定时器超时，并且至少有一个隶属于逻辑信道组的逻辑信道有待传输数据，则触发所述第五BSR，所述第五BSR不包括或包括所对应的信令中包含所述触发条件指示的逻辑信道的数据量。
需要说明的是，具体实施中，步骤S802和步骤S803选择其一进行执行。
具体地，在步骤S803的具体实施中，如果BSR重传定时器超时，并且至少有一个隶属于逻辑信道组且所对应的信令中包含或未包含 触发条件指示的逻辑信道有待传输数据，则触发第五BSR。
本实施例中，对于BSR重传定时器超时的情况，只要至少有一个隶属于逻辑信道组且所对应的信令中未包含所述触发条件指示的逻辑信道有待传输数据，则触发第五BSR，以保证待传输数据的相关信息能够通过第五BSR及时上报给基站。
在本发明一个非限制性的实施例中，请参照图9，BSR触发方法除了包括图1所示各个步骤之外，还可以包括以下步骤：
步骤S901：接收所有逻辑信道所对应的信令；
步骤S902：如果BSR周期上报定时器超时，则触发第六BSR，所述第六BSR不包括或包括所对应的信令中包含所述触发条件指示的逻辑信道的数据量。
本实施例中，BSR周期上报定时器超时，则触发第六BSR，以保证相关上行数据的相关信息能够通过第六BSR及时上报给基站。第六BSR可以不包括所对应的信令中包含所述触发条件指示的逻辑信道的数据量，也可以包括所对应的信令中包含所述触发条件指示的逻辑信道的数据量。
在本发明一个具体的应用场景中，下述任意一项事件发生，都会触发一个BSR：MAC实体中，属于某一LCG的一个LCH有上行新数据到达；并且
1、所述到达的上行新数据属于一个配置了dataVolume字段的LCH，且一次到达的数据量超过固定值的部分的大小大于第一预设门限(也即dataVolume的值)，这种情况下要触发BSR，且该BSR在上报时要包含该LCH的待传输数据量；
2、所述到达的上行新数据属于一个没有配置dataVolume字段的LCH，且该LCH的优先级高于任意一个属于某一LCG且存在上行待传输数据且没有配置dataVolume字段的LCH的优先级，这种情况下要触发BSR，且该BSR在上报时不包含或包含配置了dataVolume 字段的LCH的待传输数据量；
3、所述到达的上行新数据属于一个没有配置dataVolume字段的LCH，且配置了LCG且没有配置dataVolume字段的所有LCHs都没有上行待传输数据，这种情况下要触发BSR，且该BSR在上报时不包含或包含配置了dataVolume字段的LCH的待传输数据量。
4、存在剩余的上行资源且剩余位元(padding bits)的大小大于或等于BSR MAC CE和它的子头的大小，这种情况要触发BSR，且该BSR在上报时不包含或包含配置了dataVolume字段的LCH的待传输数据量；
5、BSR重传定时器(retxBSR-Timer)超时，并且至少有一个配置了LCG且没有配置dataVolume字段的LCH有上行待传输数据，这种情况要触发BSR，且该BSR在上报时不包含或包含配置了dataVolume字段的LCH的待传输数据量；
6、BSR周期上报定时器(periodicBSR-Timer)超时，这种情况要触发BSR，且该BSR在上报时不包含或包含配置了dataVolume字段的LCH的待传输数据量。
在本发明另一个具体的应用场景中，下述任意一项事件发生，都会触发一个BSR:MAC实体中，属于某一LCG的一个LCH有上行新数据到达；并且
1、所述到达的上行新数据属于一个配置了timeGap字段的LCH，且数据到达的时间点与时间偏移量和周期所确定的该flow数据到达的周期时间点的偏差，例如数据到达的时间点与位于所述到达的时间点之后下一个周期时间点的时间差大于第二预设门限(timeGap的值)，这种情况下要触发BSR，且该BSR在上报时要包含该LCH的待传输数据量。
2、所述到达的上行新数据属于一个没有配置timeGap字段的LCH，且该LCH的优先级高于任意一个属于某一LCG且存在上行待 传输数据且没有配置timeGap字段的LCH的优先级，这种情况下要触发BSR，且该BSR在上报时不包含或包含配置了timeGap字段的LCH的待传输数据量；或者
3、所述到达的上行新数据属于一个没有配置timeGap字段的LCH，且配置了LCG且没有配置timeGap字段的所有LCHs都没有上行待传输数据，这种情况下要触发BSR，且该BSR在上报时不包含或包含配置了timeGap字段的LCH的待传输数据量。
4、存在剩余的上行资源且剩余位元(padding bits)的大小大于或等于BSR MAC CE和它的子头的大小，这种情况要触发BSR，且该BSR在上报时不包含或包含配置了timeGap字段的LCH的待传输数据量；
5、BSR重传定时器(retxBSR-Timer)超时，并且至少有一个配置了LCG且没有配置timeGap字段的LCH有上行待传输数据，这种情况要触发BSR，且该BSR在上报时不包含或包含配置了timeGap字段的LCH的待传输数据量；

其中，上行数据确定模块1001，适于确定MAC实体中一次性到达的上行数据，所述上行数据对应逻辑信道，所述上行数据属于周期性业务，所述周期性业务中每次到达的数据量大小为固定值，所述周期性业务具备传输周期和偏移量；参数确定模块1002适于确定所述逻辑信道中每次到达的数据量对应的固定值，以及所述逻辑信道所承载的业务的传输周期和时间偏移量；BSR触发模块1003适于在所述 上行数据的数据量超过所述固定值的部分的大小达到第一预设门限时，或者，根据所述传输周期和所述偏移量确定各个周期时间点，所述上行数据到达的时间点与位于所述到达的时间点之后下一个周期时间点的时间差达到第二预设门限时，触发第一BSR，所述第一BSR包括所述上行数据的数据量。
本发明实施例对于既具有周期性又具有抖动特性的上行数据，只有在抖动发生(也即上行数据的数据量超过所述固定值的部分的大小达到第一预设门限，或者上行数据到达的时间点与位于所述到达的时间点之后下一个周期时间点的时间差达到第二预设门限)时，才会触发第一BSR，避免了在抖动未发生时占用上行资源发送没有必要的BSR导致上行资源的浪费；通过第一BSR将上行数据的数据量进行上报，以使得基站能够获取到抖动发生时产生的基站未知数据量，进而能够为该上行数据配置相应的上行资源，保证上行数据的及时有效传输，减小数据传输时延。
关于所述BSR触发装置100的工作原理、工作方式的更多内容，可以参照图1至图9中的相关描述，这里不再赘述。
