具体实施方式
下面结合附图及实施例对本公开再作进一步详细的描述。
相关技术中，终端可以在接收到基站(比如下一代基站(the next Generation Node B，gNB))发送的上行授权(UL Grant)后在物理上行共享信道(Physical Uplink Shared Channel，PUSCH)上发送数据。在PUSCH上发送数据时，终端需要先在物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)上向基站发送调度请求(Schedule Request，SR)来请求上行资源。然而，SR只能指示是否有上行数据，无法向网络侧传送上行数据的优先级、所属逻辑信道、缓存大小等信息，因此，基站接收到SR后，会为终端分配上行资源以供终端发送BSR MAC CE，BSR MAC CE的作用是将终端当前缓存区内待发送数据的情况通知给基站，后续基站可以根据终端上报的BSR MAC CE中携带的LCG缓存信息为终端分配PUSCH资源。
其中，非自回传节点(Integrated Access and Backhaul，IAB)终端可以使用图1和图2所示的格式向网络侧上报BSR MAC CE，相关技术规定当终端仅配置了一个LCG或仅有一个LCG的缓存区内存在待发送数据时只能向网络侧发送图1所示的缓存大小(Buffer Size)字段为5比特(bit)的Short类型的BSR MAC CE，只有当终端有大于一个LCG的缓存区内存在待发送数据时才可以向网络侧发送图2所示的Buffer Size字段为8bit的Long类型的BSR MAC CE，Short BSR MAC CE对应的缓存大小的上报颗粒度大于Long BSR MAC CE对应的缓存大小的上报颗粒度。由于Short BSR MAC CE的Buffer Size字段所对应的缓存数据的最大非上限值为150千字节(KB)，且该字段长度最大为5bit，所以Short BSR MAC CE的Buffer Size字段对应32个颗粒度较大的缓存大小区间，即32个缓存大小的上报等级，上报等级之间的差距(即上报颗粒度)较大。
另外，如图1和图2所示，传统的BSR MAC CE仅包含LCG标识符(Identifier，ID)字段和Buffer Size字段，虽然LCG ID字段可以反映缓存区内待发送数据的优先级和所属逻辑信道，Buffer Size字段可以反映缓存区内待发送数据的大小区间，但网络侧无法从BSR MAC CE中获得缓存区内待发送数据的延迟要求等能够表征待发送数据的精细化的传输需求的信息；换句 话说，BSR MAC CE中携带的缓存信息较少，网络侧根据BSR MAC CE为终端分配的传输资源可能无法满足终端缓存的待发送数据的精细化的传输需求。
基于此，在本公开的各种实施例中，BSR MAC CE携带至少表征终端的待发送数据的传输需求且至少用于辅助网络侧分配传输资源的第一信息，如此，网络侧根据BSR MAC CE为终端分配传输资源时能够考虑到终端缓存的待发送数据的精细化的传输需求，比如待发送数据的延迟要求等；换句话说，网络侧至少能够基于所述第一信息为终端分配传输资源，从而使得网络侧为终端分配的传输资源能够满足终端缓存的待发送数据的精细化的传输需求，进而能够提高上行数据传输的效率。
本公开实施例提供了一种信息传输方法，应用于终端，该方法包括：
向网络侧发送BSR MAC CE，所述BSR MAC CE包含第一信息，所述第一信息至少表征所述终端的待发送数据的传输需求，所述第一信息至少用于辅助所述网络侧分配传输资源。
这里，可以理解，所述BSR MAC CE用于将所述终端当前缓存区内待发送数据的情况通知给所述网络侧，以供所述网络侧为所述终端分配传输资源，本公开实施例对所述BSR MAC CE的名称不作限定，只要实现其功能即可。
实际应用时，所述终端可以包括非IAB终端。另外，所述终端可以称为用户设备(User Equipment，UE)，还可以称为用户。
实际应用时，所述第一信息也可以称为辅助信息等，本公开实施例对所述第一信息的名称不作限定，只要实现其功能即可。
实际应用时，所述第一信息可以是LCG级的信息，即一个LCG可以对应一个第一信息。相应地，在所述终端仅配置了一个LCG或仅有一个LCG的缓存区内存在待发送数据的情况下，所述BSR MAC CE包含一个第一信息；在所述终端有多个(即至少两个)LCG的缓存区内存在待发送数据的情况下，所述BSR MAC CE包含多个(即至少两个)第一信息；换句话说，所述BSR MAC CE可以包含一个或多个第一信息，即包含至少一个第一信息，一个第一信息对应一个LCG。
实际应用时，所述终端与所述网络侧建立无线承载后，所述网络侧可以根据无线承载对应的业务类型和/或服务质量(Quality of Service，QoS)参数 (比如包延迟预算、最大突发数据容量等)等信息为所述终端的每个LCG配置相同或不同类型的第一信息。在每个LCG对应的第一信息的类型相同的情况下，所述BSR MAC CE可以包含第一字段，所述第一字段可以包含所述第一信息。在存在不同类型的第一信息的情况下，所述BSR MAC CE还可以包含第二字段，所述第二字段可以指示所述第一信息的类型，即所述BSR MAC CE可以包含所述第一字段和第二字段。
实际应用时，所述第一字段也可以称为值(Value)字段等，所述第二字段也可以称为类型(Type)字段等，所述第一字段和第二字段可以统称为辅助信息字段等，本公开实施例对所述第一字段和第二字段的名称不作限定，只要实现其功能即可。
实际应用时，所述第一信息可以理解为本次上报的对应LCG的缓存信息(即传统的LCG ID字段和Buffer Size字段)的补充内容或增强内容，即所述第一信息用于在传统的LCG ID字段和Buffer Size字段的基础上反映所述待发送数据的精细化的传输需求；换句话说，除所述第一字段、第二字段外，所述BSR MAC CE还可以包含传统的LCG ID字段和Buffer Size字段。另外，由于Short格式和Long格式的BSR MAC CE的长度不一致，所述第一字段、第二字段的长度也可以根据需求设置。示例性地，在所述终端仅配置了一个LCG或仅有一个LCG的缓存区内存在待发送数据的情况下，所述BSR MAC CE为Short类型的BSR MAC CE，该Short类型的BSR MAC CE的结构可以如图3所示，Buffer Size字段的长度变为8bit，辅助信息字段的长度为5bit，其中Type字段(即第二字段)的长度为2bit，Value字段(即第一字段)的长度为3bit；或者Value字段的长度为5bit，不包含Type字段。在所述终端有多个(即至少两个)LCG的缓存区内存在待发送数据的情况下，所述BSR MAC CE为Long类型的BSR MAC CE，该Long类型的BSR MAC CE的结构可以如图4所示，辅助信息字段的长度为8bit，其中Type字段(即第二字段)的长度为3bit，Value字段(即第一字段)的长度为5bit；或者Value字段的长度为8bit，不包含Type字段。
其中，在缓存数据的最大非上限值不变(比如150KB)的情况下，与图1所示的Short类型的BSR MAC CE中能够指示32个颗粒度较大的缓存大小 区间的、5bit的Buffer Size字段相比，由于图3所示的Short类型的BSR MAC CE中Buffer Size字段的长度变为8bit，所以图3中的Buffer Size字段能够指示28个精细化的缓存大小区间，从而能够实现更细颗粒度的、更精准的缓存大小信息上报，进而使得所述网络侧后续能够更精准地为所述终端分配传输资源。
另外，需要说明的是，在图4所示的Long类型的BSR MAC CE结构中，Buffer Size字段和辅助信息字段的顺序可以调换，即Oct 2对应LCG0缓存大小、Oct 3对应LCG0辅助信息、…Oct 2m对应LCGm缓存大小、Oct 2m+1对应LCGm辅助信息，但一个BSR MAC CE中不可以同时存在两种Buffer Size字段和辅助信息字段的排列顺序。其中，Oct即OCT。
在一实施例中，所述第一信息(即所述第一信息的类型、也即所述第二字段的类型)可以包括表1所示的一项或多项内容，所述网络侧接收到所述第一信息后，至少可以根据所述第一信息为所述终端分配传输资源，或者可以结合所述第一信息、所述BSR MAC CE中的LCG ID字段、Buffer Size字段包含的信息为所述终端分配传输资源。其中，所述为所述终端分配传输资源，可以理解为进行所述待发送数据的相关调度。
表1

其中，所述待发送数据对应的最早生成时间可由所述终端的MAC层自 身感知，即由所述MAC层感知对应LCG的缓存区距离上一次清空到发送所述BSR MAC CE空口的时间间隔。该信息可以用于指示对应缓存区内的最早数据，从而供对端调度器(即所述网络侧的调度器)优化调度，示例性地，所述第一字段与所述待发送数据对应的最早生成时间之间的关联关系可以如表2所示，所述网络侧接收到所述第一信息后，可以根据所述待发送数据对应的最早生成时间，判断所述待发送数据在终端侧的积压时间(即时长)是否大于预设的积压时间门限值，并可以根据判断结果确定所述待发送数据对应的调度优先级。
表2
实际应用时，在所述第一信息对应LCG的缓存区内存在多个待发送的数据包的情况下，可以将这些数据包对应的最短的延迟预算确定为所述待发送数据的延迟预算。所述待发送数据的延迟预算可以用于指示对应业务对所述待发送数据的需求的时间紧迫程度，从而供对端调度器(即所述网络侧的调度器)优化调度，示例性地，所述第一字段与所述待发送数据的延迟预算之间的关联关系可以如表3所示，所述网络侧接收到所述第一信息后，可以根据所述待发送数据的延迟预算确定所述待发送数据对应的调度优先级，比如当延迟预算接近过期但还未过期时，所述待发送数据对应的调度优先级较高，当延迟预算充裕或过期很久时，所述待发送数据对应的调度优先级较低；这里，判断延迟预算是否接近过期、延迟预算是否充裕、延迟预算是否过期很久的门限可以根据需求来设置，本公开实施例对此不作限定。
表3
实际应用时，所述网络侧可以根据所述待发送数据对应的最早生成时间和/或所述待发送数据的延迟预算，确定所述待发送数据的时间有效性，并基于所述待发送数据的时间有效性，进行所述待发送数据的相关调度，从而能够使所述网络侧为所述终端分配的传输资源能够满足所述待发送数据的精细化的传输需求。示例性地，在根据所述待发送数据对应的最早生成时间确定所述待发送数据在终端侧的积压时间大于预设的积压时间门限值的情况下，和/或，在延迟预算接近过期但还未过期的情况下，所述网络侧可以确定所述待发送数据具备时间有效性，并可以优先进行所述待发送数据的相关调度；在根据所述待发送数据对应的最早生成时间确定所述待发送数据在终端侧的积压时间小于或等于预设的积压时间门限值的情况下，和/或，在延迟预算充裕或过期很久的情况下，所述网络侧可以确定所述待发送数据不具备时间有效性，并可以优先进行除所述待发送数据的相关调度外的其他调度。这里，所述积压时间门限值、判断延迟预算是否接近过期、延迟预算是否充裕、延迟预算是否过期很久的门限均可以根据需求来设置，本公开实施例对此不作限定。
实际应用时，与传统BSR MAC CE仅包含LCG ID字段的上报方式相比，所述终端向所述网络侧上报所述待发送数据对应的逻辑信道标识，能够使BSR MAC CE的上报颗粒度更为精细。所述待发送数据对应的逻辑信道标识用于指明所述待发送数据对应的逻辑信道，且隐含了优先级、QoS需求等信息，对端调度器(即所述网络侧的调度器)可以根据优先级、QoS需求等信息确定所述待发送数据对应的调度优先级和调度参数(比如码率、调制阶数、 是否重传等)。
实际应用时，所述网络侧可以根据所述待发送数据的类型确定所述待发送数据对应的调度优先级和调度参数。另外，在所述待发送数据的类型为视频数据的情况下，所述终端的MAC层可以从应用层内的视频编码器获取所述待发送数据的类型。
实际应用时，可以理解，所述第四信息所指示的区间是所述第一缓存大小范围被划分的N个区间中的一个区间，N的大小与所述第四信息的长度(即所述第四信息对应的bit数)相关，示例性地，在所述第四信息的长度为3bit的情况下，N＝23＝8。
另外，所述BSR MAC CE包含的Buffer Size字段可以通过缓存大小范围Index指示所述待发送数据实际的缓存大小范围，缓存大小范围Index与实际的缓存大小范围之间的关联关系可以如表4所示，表4可以预先配置在所述网络侧和所述终端，或者由所述网络侧配置给所述终端。示例性地，假设所述第四信息的长度为3bit，并假设所述BSR MAC CE包含的Buffer Size字段对应的缓存大小范围Index为16，即所述BSR MAC CE包含的Buffer Size字段所指示的缓存大小范围为[1446，2014)，也即所述第一缓存大小范围为[1446，2014)；则所述第一缓存大小范围可以被均匀地划分为8个区间(即8个缓存大小的上报等级)，换句话说，可以按粒度71(即(2014-1446)/8＝71)对所述第一缓存大小范围[1446，2014)进行均匀划分，得到[1446，1517)、[1517，1588)、[1588，1659)、[1659，1730)、[1730，1801)、[1801，1872)、[1872，1943)、[1943，2014)共8个区间，所述第四信息可以指示这8个区间中的一个区间，从而能够实现更细颗粒度的、更精准的缓存大小信息上报，进而使得所述网络侧后续能够更精准地为所述终端分配传输资源。这里，可以理解，所述第四信息能够结合所述BSR MAC CE包含的Buffer Size字段精细化地指示所述待发送数据的大小在第一缓存大小范围的区间，所述第四信息也可以称为扩展bit、扩展缓存信息、扩展信息、扩展缓存字段等，本公开实施例对所述第四信息的名称不作限定，只要实现其功能即可。
表4
实际应用时，所述网络侧根据所述待发送数据的TBS需求，能够在对应LCG的缓存区内具有多种不同重要性和/或优先级的待发送数据时，为所述终端调度最符合所述待发送数据需求的最小的TBS，以避免影响数据传输效率进而造成卡顿等问题从而影响用户体验。比如，在所述终端的缓存区内缓存大量视频帧的情况下，所述网络侧需要调度I帧大小的TBS；在所述终端使用分层视频编码的情况下，所述网络侧需要调度基础层的视频帧大小的TBS；在所述终端缓存区内，延迟预算将在未来N次调度中被完全消耗的数据包大小的TBS。
实际应用时，所述终端通过所述待发送数据对应的数据包相关性信息，能够向所述网络侧指示调度器对应的TBS与其他已发送和/或未发送的TBS的之间的对应关系，在一些特定情况下，具有关联的TBS的信息即使传递失败也可能被其他手段恢复；换句话说，所述网络侧可以根据所述待发送数据对应的数据包相关性信息恢复丢失的数据包，从而精准地为所述终端分配传输资源。
实际应用时，为了减少所述BSR MAC CE的开销，可以根据所述待发送数据的传输需求的优先级(也可以理解为重要性)，将所述第一信息划分为两类：需要向所述网络侧频繁上报的第一信息(后续描述中记作第二信息)和不需要向所述网络侧频繁上报的第一信息(后续描述中记作第三信息)。
基于此，在一实施例中，所述第一信息可以包含第二信息和/或第三信息，所述第二信息至少表征所述待发送数据的第一传输需求，所述第三信息至少 表征所述待发送数据的第二传输需求，所述第一传输需求的优先级高于所述第二传输需求的优先级。
实际应用时，所述第二信息也可以称为主辅助信息等，所述第三信息也可以称为辅辅助信息等，本公开实施例对所述第二信息和第三信息的名称不作限定，只要实现其功能即可。
实际应用时，可以理解，所述第二信息、第三信息的类型均可以包含表1所示的一项或多项内容，且所述第二信息和第三信息均为LCG级的信息，不同LCG对应的第二信息及第三信息可以相同或不同。具体地，在与所述终端开始建立无线承载后，所述网络侧可以根据无线承载对应的业务类型和/或QoS参数(比如包延迟预算、最大突发数据容量等)等信息为所述终端的每个LCG确定所述第二信息和第三信息的类型。示例性地，针对语音、直播、虚拟现实(Virtual Reality，VR)、增强现实(Augmented Reality，AR)、扩展现实(eXtended Reality，XR)等业务以及数据包延迟预算(Packet Delay Budget，PDB)较低的业务，所述网络侧可以为对应的LCG配置第二信息的类型包含所述待发送数据的延迟预算；针对数据突发性比较强的数据，所述网络侧可以为对应的LCG配置第二信息的类型包含所述第四信息；针对当前LCG中资源块(Resource Block，RB)数量超过预设RB门限的情况，所述网络侧可以为该LCG配置第二信息的类型包含所述待发送数据对应的逻辑信道标识；针对LCG中混合多种重要性不同的数据的情况，所述网络侧可以为该LCG配置第二信息的类型包含所述待发送数据的类型；为一个LCG配置第二信息后，所述网络侧可以从表1所示的多项内容中选择除配置的第二信息外的一项或多项作为该LCG的第三信息。
实际应用时，所述网络侧配置的第二信息、第三信息的类型数不应超过所述第二字段能够指示的类型数。示例性地，针对图3所示的Short类型的BSR MAC CE，由于所述第二字段的最大长度为2bit，所述网络侧可以配置一种第二信息和不超过三种的第二信息；针对图4所示的Long类型的BSR MAC CE，由于所述第二字段的最大长度为3bit，所述网络侧可以配置一种第二信息和不超过七种的第二信息。
实际应用时，所述网络侧向所述终端配置每个LCG对应的第二信息的类 型和/或第三信息的类型时，如果没有配置一个LCG对应的第二信息和第三信息的类型，即没有为该LCG配置第一信息的类型，则所述终端可以不向所述网络侧上报该LCG对应的第一信息，即向所述网络侧发送传统格式的BSR MAC CE；或者，所述终端可以自动设置该LCG对应的第一信息包含所述第四信息，以实现更细颗粒度的、更精准的缓存大小信息上报。
实际应用时，所述网络侧向所述终端配置每个LCG对应的第二信息的类型和/或第三信息的类型时，还需要向所述终端配置对应的第二信息和/或第三信息的上报条件。具体地，所述网络侧可以向所述终端发送第六信息，所述第六信息可以指示所述第一信息的类型与LCG之间的关联关系；向所述终端发送所述第六信息时，所述网络侧还可以向所述终端发送第五信息，所述第五信息可以指示所述第一信息的上报条件。
基于此，在一实施例中，该方法还可以包括：
接收所述网络侧发送的第六信息，所述第六信息指示所述第一信息的类型与LCG之间的关联关系。
其中，所述第六信息具体可以指示所述第二信息和/或第三信息的类型与LCG之间的关联关系。
在一实施例中，接收所述网络侧发送的第六信息时，该方法还可以包括：
接收所述网络侧发送的第五信息，所述第五信息指示所述第一信息的上报条件。
其中，所述第一信息的上报条件(即所述第二信息和/或第三信息的上报条件)包括以下至少之一：
时间触发上报的条件；
事件触发上报的条件；
禁止触发上报的条件；
禁止上报的时长。
实际应用时，所述终端可以基于所述第五信息和第六信息，向所述网络侧发送所述BSR MAC CE。
实际应用时，所述网络侧可以根据需求(比如负载情况等)来配置所述第二信息和/或第三信息的上报条件。示例性地，所述第二信息和第三信息的 上报条件可以如表5所示，针对表5所示的配置，第二信息为未触发第三信息上报时BSR MAC CE默认携带的辅助信息，所述网络侧可以为第二信息配置禁止触发上报的门限，第二信息对应的测量值满足禁止触发上报的门限时所述终端可以不向所述网络侧发送携带第二信息的BSR MAC CE；如果所述网络侧没有为第二信息配置禁止触发上报的门限，则所述终端上报的BSR MAC CE默认携带第二信息。第三信息是需要满足特定触发条件才允许触发上报的辅助信息，可独立于第二信息触发上报，即触发上报的条件可以与第二信息不同。并且，可以通过禁止定时器实现在当前类型的第三信息触发上报后的一段时间内不允许上报同类型的第三信息以避免干扰第二信息的上报。
表5

实际应用时，针对第二信息，如表5所示，所述网络侧还可以配置触发上报BSR MAC CE的门限，即在第二信息对应的测量值满足该门限的情况下主动触发所述终端向所述网络侧发送包含第二信息的BSR MAC CE。这里，可以配置第三信息仅能够被已触发的BSR MAC CE携带，不能单独触发BSR MAC CE的上报。
实际应用时，如表5所示，第三信息的触发方式包括时间触发方式和事件触发方式，不同类型的第三信息可以对应不同的配置(即上报条件)。所述网络侧配置时间触发上报的条件时，可以配置上报周期；所述终端可以在超过上报周期时向所述网络侧上报携带对应第三信息的BSR MAC CE。所述网络侧配置事件触发上报的条件时，可以配置事件触发上报的门限、禁止触发上报的门限和禁止定时器，当第三信息对应的测量值满足事件触发上报的门限时，所述终端可以向所述网络侧发送携带对应第三信息的BSR MAC CE， 并启动对应第三信息的禁止定时器，在该禁止定时器过期之前禁止再次向所述网络侧携带同类型的第三信息；所述终端每上报一次第三信息，可以启动对应的禁止定时器。当第三信息的测量值满足禁止触发上报的门限时，所述终端可以停止上报对应的第三信息，并删除对应的禁止定时器。
实际应用时，在所述终端自身的配置不支持向所述网络侧上报除所述第四信息外的其他类型的第一信息、但所述网络侧配置所述终端上报除所述第四信息外的其他类型的第一信息的情况下，所述终端可以仅向所述网络侧上报包含所述第四信息的BSR MAC CE，即所述终端向所述网络侧发送的BSR MAC CE默认携带所述第四信息。此时，在所述BSR MAC CE包含所述第二字段的情况下，所述第二字段对应的bit也可以用于扩展所述第一字段携带信息(即所述第四信息)的颗粒度，换句话说，所述第四信息也可以包含所述第二字段对应的内容，所述第二字段可以与所述第一字段结合并指示所述待发送数据的大小在所述第一缓存大小范围的区间，从而能够实现更细颗粒度的、更精准的缓存大小信息上报。
实际应用时，如图5所示，基站(比如gNB)与终端建立无线承载后，可以根据业务类型和/或QoS参数(比如包延迟预算、最大突发数据容量等)等信息确定主辅助信息(即第二信息)的种类和上报条件，并确定辅辅助信息(即第三信息)的种类和上报条件；之后，基站可以向终端配置主辅助和辅辅助信息的种类和上报条件。终端可以根据基站的配置，向基站上报携带主辅助信息的BSR MAC CE；在满足辅辅助信息1的触发门限时向基站上报携带辅辅助信息1的BSR MAC CE，并启动辅助信息1的禁止定时器；在该禁止定时器未到期、且满足辅辅助信息2的触发门限时向基站上报携带辅辅助信息2的BSR MAC CE，不再向基站上报携带辅辅助信息1的BSR MAC CE；在该禁止定时器到期后，向基站上报携带辅辅助信息1的BSR MAC CE；在满足辅辅助信息1的禁止触发门限时删除该禁止定时器。
相应地，本公开实施例还提供了一种信息传输方法，应用于网络设备(具体可以包括基站，比如gNB)，该方法包括：
接收终端发送的BSR MAC CE，所述BSR MAC CE包含第一信息，所述第一信息至少表征所述终端的待发送数据的传输需求，所述第一信息至少用 于辅助网络侧分配传输资源。
其中，在一实施例中，该方法还可以包括：
向所述终端发送第五信息，所述第五信息指示所述第一信息的上报条件。
相应地，本公开实施例还提供一种信息传输方法，如图6所示，该方法包括：
步骤601：终端向网络侧发送BSR MAC CE，所述BSR MAC CE包含第一信息，所述第一信息至少表征所述终端的待发送数据的传输需求，所述第一信息至少用于辅助所述网络侧分配传输资源；
步骤602：所述网络侧接收所述终端发送的所述BSR MAC CE。
本公开实施例提供的信息传输方法，终端向网络侧发送BSR MAC CE，所述BSR MAC CE包含第一信息，所述第一信息至少表征所述终端的待发送数据的传输需求，所述第一信息至少用于辅助所述网络侧分配传输资源；所述网络侧接收所述终端发送的所述BSR MAC CE。本公开实施例提供的方案，由于BSR MAC CE携带了至少表征终端的待发送数据的传输需求且至少用于辅助网络侧分配传输资源的第一信息，所以网络侧根据BSR MAC CE为终端分配传输资源时能够考虑到终端缓存的待发送数据的精细化的传输需求，比如待发送数据的延迟要求等；换句话说，网络侧至少能够基于所述第一信息为终端分配传输资源，从而使得网络侧为终端分配的传输资源能够满足终端缓存的待发送数据的精细化的传输需求，进而能够提高上行数据传输的效率。
另外，在本公开的各种实施例中，BSR MAC CE可以携带多种类型的辅助信息(即第一信息)，从而至少能够解决BSR MAC CE携带信息过少和缓存大小颗粒度较大的问题，并且，所述网络侧后续能够利用多种类型的辅助信息辅助调度传输资源，从而能够提升网络效能。
为了实现本公开实施例终端侧的方法，本公开实施例还提供了一种信息传输装置，设置在终端上，如图7所示，该装置包括：
第一发送单元701，用于向网络侧发送BSR MAC CE，所述BSR MAC CE包含第一信息，所述第一信息至少表征所述终端的待发送数据的传输需求，所述第一信息至少用于辅助所述网络侧分配传输资源。
其中，在一实施例中，如图7所示，该装置还可以包括第一接收单元702， 用于接收所述网络侧发送的第五信息，所述第五信息指示所述第一信息的上报条件。
实际应用时，所述第一发送单元701和第一接收单元702可由所述终端中的通信接口实现。

实际应用时，所述第二接收单元801和第二发送单元802可由所述网络设备中的通信接口实现。
