Therefore, the long BSR format can report the Buffer Sizes of 8 LCGs to the base station together.

Logical channels with high priority) need to be transmitted, and the terminal will trigger the BSR to report. This BSR is called "Regular BSR".
  • Event 3 The terminal periodically updates its buffer status to the base station: the base station configures a periodic BSR timer (also called periodicBSR-timer) for the terminal. If the periodicBSR-timer times out, the terminal will trigger a BSR report. For example: when the terminal needs to upload a large file, the time when the data reaches the terminal transmission buffer is not synchronized with the time when the terminal receives the uplink authorization. Fill data into the uplink transmission buffer, so the terminal needs to constantly update the amount of uplink data to be transmitted.

Rather than being used as a padding bit, it is better to use it to transmit useful data such as BSR. So when the number of padding bits is equal to or greater than the size of "BSR MAC CE + corresponding subheader", the terminal will use these bits to send BSR.

Description

一种缓存状态报告发送方法及通信装置
本申请要求于2021年12月25日提交于中国专利局、申请号为202111605541.3、申请名称为“一种缓存状态报告发送方法及通信装置”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
本申请涉及通信技术领域，尤其涉及一种缓存状态报告发送方法及通信装置。
背景技术
在上行传输过程中，用户设备(user equipment，UE)有上行数据需要传输时，UE需要通过上行调度请求(scheduling request，SR)请求基站进行上行资源调度，并通过缓存状态报告(buffer state report，BSR)上报逻辑信道组(logical channel group，LCG)待传输上行数据的数据量，以便基站为每个LCG分配足够的上行资源进行上行数据的传输。
UE借助BSR进行上报LCG的待传输上行数据的数据量的具体过程可以理解为：终端将LCG的待传输上行数据的数据量进行量化，以确定该LCG的待传输上行数据的数据量对应的缓存状态(buffer state，BS)区间的索引值，并上报该LCG的待传输上行数据的数据量对应的BS区间的索引值。基站会根据该索引值对应的量化区间的最大值为终端分配上行传输资源。
通常BSR会有比特长度限制，所能划分的BS区间个数是有限的。对于扩展现实(extended reality，XR)等强交互类媒体业务，存在着主动丢包机制，即在用户缓存中等待时间超过一定阈值的包会进行丢弃，因此这类业务的缓存区中通常具有一定数量的待传数据，而BS区间的涵盖范围可能远超过待传数据量的大小，导致BSR上报不准确，基站分配的资源可能会远大于终端实际需要的资源，从而造成传输资源的浪费。
发明内容

(无线)接入网((radio)access network，(R)AN)用于将终端设备接入到无线网络。需要知晓的是，为了方便描述在后文中将(R)AN描述为RAN。RAN中可以包括一个或多个RAN设备(或者说接入网设备)，即接入网设备可以理解为将终端接入到无线网络的节点或设备。
接入网设备与终端之间的接口可以为Uu接口(或称为空口)。当然，在未来通信中，这些接口的名称可以不变，或者也可以用其它名称代替，本申请对此不限定。接入网设备可以是任意一种具有无线收发功能的设备，包括但不限于：LTE中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，NR中的基站(gNodeB或gNB)或传输接收点(transmissionreception point，TRP)，第三代合作伙伴项目(the 3rd generation partner project，3GPP)后续演进的基站，WiFi系统中的接入节点，无线中继节点，无线回传节点等。基站可以是：宏基站，微基站，微微基站，小站，中继站，或，气球站等。多个基站可以支持上述提及的同一种技术的网络，也可以支持上述提及的不同技术的网络。基站可以包含一个或多个共站或非共站的TRP。接入网设备还可以是云无线接入网(cloud radio access network，CRAN)场景下的无线控制器、集中单元(central unit，CU)，和/或分布单元(distributed unit，DU)。接入网设备还可以是服务器，可穿戴设备，或车载设备等。以下以接入网设备为基站为例进行说明。所述多个接入网设备可以为同一类型的基站，也可以为不同类型的基站。基站可以与终端进行通信，也可以通过中继站与终端进行通信。终端可以与不同技术的多个基站进行通信，例如，终端可以与支持LTE网络的基站通信，也可以与支持5G网络的基站通信，还可以支持与LTE网络的基站以及5G网络的基站的双连接。可以理解，本申请中的接入网设备的全部或部分功能也可以通过在硬件上运行的软件功能来实现，或者通过平台(例如云平 台)上实例化的虚拟化功能来实现。
需要知晓的是，接入网设备和终端之间的通信遵循一定的协议层结构。例如请参见图2a所示，接入网设备和终端之间遵循用户面协议层结构可以包括无线资源控制(radio resource control，RRC)层、分组数据汇聚层协议(packet data convergence protocol，PDCP)层、无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层、物理层(physical layer，PHY层)和业务数据适配(service data adaptation protocol，SDAP)层；控制面协议层结构可以包括PDCP层、RLC层、MAC层和物理层。
请参见图2b，图2b为本申请提供的一种各协议层之间映射关系的示意图。从图2b中可见，PHY层为MAC层提供传输信道(transportchannel)；MAC为RLC提供逻辑信道(logicalchannel，LC)；RLC层为PDCP层提供RLC信道(RLCchannel)；PDCP层为SDAP层提供无线承载(radiobear，RB)；SDAP层负责上行(uplink，UL)/下行(downlink，DL)服务质量流(quality of service flow，QoSFlow)与RB之间的映射。
示例性地，请参见图2c，图2c为本申请提供的一种用户面数据流映射关系的示意图。在图2c中业务数据在网络传输层分成多个的网际协议(internet protocol，IP)包，每个UL/DL的IP包中标记着该IP包对应QoSFlow的标识(QoS Flow ID，QFI)。SDAP层根据每个IP包的QFI，得到多个UL/DL QoSFlow，进一步地，SDAP层将多个UL/DL QoSFlow映射于至少一个RB上，其中一个RB可以映射一个或多个QoSFlow，而一个QoS Flow每次只能映射到一个RB上。PDCP层负责将RB上的数据包映射于RLC信道中，每个RLC信道对应一个RB。RLC层负责RLC信道到逻辑信道的映射，每个逻辑信道对应一个RLC信道，也对应一个RB。MAC层负责逻辑信道的调度和复用，根据优先级对逻辑信道进行调度，并且可以将多个逻辑信道复用到同一个传输信道上，递交给PHY层进行传输。
为了便于对本方案技术方案的理解，下面对本申请中所涉及到的部分术语进行解释说明。
1、扩展现实(extended reality，XR)
XR是指通过计算机将真实与虚拟相结合，打造一个可人机交互的虚拟环境。XR包括VR和AR，通常XR业务具有低丢包率和低时延的传输需求。
2、主动超时丢包机制
由于XR业务具有低时延的传输需求，则XR业务的视频帧需要在一定的时间内(即时延预算)从服务器传输到终端(或从终端传输到服务器)。以上行数据从终端传输至服务器为例，若在空口传输的过程中出现拥堵，当XR业务的视频帧在终端的缓存(buffer)中的等待时间超过时延预算的情况下，终端会将超时的XR数据包进行丢弃，从而节省出传输资源，保证后续视频帧的成功传输。
3、缓存状态报告
若终端没有待上传的上行数据，接入网设备却为终端分配了传输上行数据的上行传输资源，将会造成传输资源浪费。为了避免这种传输资源浪费的情况，长期演进(long term evolution，LTE)技术和新空口(new radio，NR)技术提供了SR机制。在SR机制中，终端向基站发送SR，该SR用于通知终端需要上行传输资源用于传输上行数据；终端向基站上报BSR，该BSR用于指示终端待传输的上行数据的数据量大小；进一步地，基站根据BSR为终端配置传输上行数据的上行传输资源。
在LTE和NR系统中，通常终端以LCG对应的待传输数据为上报粒度，向接入网设备发送BSR。关于LCG的划分，通常取决于接入网设备的算法实现，例如接入网设备可以将相同QoS需求的逻辑信道划分为同一LCG，或者，将相同优先级(priority)的逻辑信道划分为同 一LCG。由于终端的LCG和逻辑信道的配置是由基站控制的，所以基站知道每个LCG包含哪些逻辑信道以及这些逻辑信道的优先级。虽然基站无法知道一个单独的逻辑信道的缓存状态，但由于同一LCG中的逻辑信道有着类似的QoS/priority需求，所以基于LCG来上报缓存状态也可以使得上行调度提供合适的调度结果。下面以NR系统为例，终端向接入网设备上报BSR进行示意性说明。
在NR系统中，BSR通过MAC层的BSR MAC控制单元(control element，CE)上报，上报的BSR包含2中格式：短BSR(又称short BSR)格式、长BSR(又称long BSR)格式。
3.1、short BSR
short BSR也可称为截短BSR(Truncated BSR)。在short BSR中只上报一个LCG的待传输数据量，该short BSR格式BSR的示意图可参见图3a所示，在图3a中该short BSR格式BSR由一个LCG ID域和一个缓存大小(buffer size)域组成。在short BSR格式中，用5位比特(bit)位来指示BS中的数值大小(即用5位bit来上报BS区间的索引值(index)，short BSR格式中有32个BS区间)。short BSR的buffer size域与BS中的数值(value)对应关系如表1所示。
表1

1 ≤10 9 ≤142 17 ≤2014 25 ≤28581

7 ≤74 15 ≤1038 23 ≤14726 31 >150000
例如，基于表1中buffer size域与BS中的数值对应关系，当该LCG的缓存数量小于等于10Bytes时，图3a中buffer size域的索引值为1；当该LCG中的缓存数量大于276Bytes并且小于等于384Bytes，buffer size域的索引值为12。
3.2、long BSR
long BSR格式BSR的示意图可参见图3b所示，在图3b中该long BSR格式BSR中由8个LCG ID域(即图3b中LCG0～LCG7)和m个缓存大小(即图3b中的buffer size)域组成。若LCG i为该8个LCG ID域中的任一个，当LCG i为1时，则表示对第i个LCG的BS进行了上报；否则(当LCG i不为1时)，则表示对第i个LCG的BS未进行上报。因此，该long BSR格式可以将8个LCG的Buffer Size一起上报给基站。在long BSR格式中，用8位bit位来指示BS中的数值大小(即用8位bit来上报BS区间的索引值(index)，long BSR格式中有256个BS区间)。long BSR的buffer size域与BS中的数值对应关系如表2所示。

当如下任一项事件发生时，终端侧将会触发以long BSR格式向接入网设备上报BSR：
事件1、终端的上行数据buffer为空且有新数据到达：当所有LCG的所有逻辑信道都没有可发送的上行数据时，如果此时属于任意一个LCG的任意一个逻辑信道有数据变得可以发送，则终端会触发BSR上报。例如：终端第一次发送上行数据。该BSR被称为常规BSR(又称Regular BSR)。
事件2、高优先级的数据到达：如果终端已经发送了一个BSR，并且正在等待上行授权(uplink grant)，此时有更高优先级的数据(即该数据所属的逻辑信道比任意一个LCG的逻辑信道的优先级都要高)需要传输，则终端会触发BSR上报。该BSR被称为“Regular BSR”。
事件3、终端周期性地向基站更新自己的buffer状态：基站为终端配置了一个周期性BSR定时器(又称periodicBSR-timer)，如果该periodicBSR-timer超时，终端会触发BSR上报。例如：当终端需要上传一个大文件时，数据到达终端传输buffer的时间与终端收到上行授权的时间是不同步的，也就是说终端在发送BSR和接收上行授权的同时，还在不停地往上行传输buffer里填数据，因此终端需要不停地更新需要传输的上行数据量。该BSR被称为周期性BSR(又称Periodic BSR)。
事件4、为提高BSR的健壮性，LTE和NR都提供了一个重传BSR的机制：这是为了避免终端发送了BSR却一直没有收到上行授权的情况。基站为终端配置了一个重传BSR定时器(又称retxBSR-timer)，当该retxBSR-timer超时且终端的任意一个LCG的任意一个逻辑信道里有数据可以发送时，将会触发BSR。该BSR被称为“Regular BSR”。当终端收到一个新传数据的上行授权时，都会重启retxBSR-timer。
事件5、废物再利用：当终端有上行资源且发现需要发送的数据不足以填满该资源时，多余出来的比特会作为padding bit而被填充一些无关紧要的值。与其用作padding bit，还不如用来传BSR这些有用的数据。所以当padding bit的数量等于或大于“BSR MAC CE+对应的subheader”的大小时，终端会使用这些比特来发送BSR。该BSR被称为填充BSR(又称Padding BSR)。
对于Regular BSR和Periodic BSR而言，如果在该时隙(slot)内有多于1个LCG中有数据需要发送，则上报Long BSR；否则上报Short BSR。对于Padding BSR而言，当padding bit的数量等于或大于“Short BSR+对应的subheader”的大小但小于“Long BSR+对应的subheader”的大小时，如果在该slot内有多于1个LCG中有数据需要发送，则将有数据要发送且优先级最高的逻辑信道所在的LCG的BSR上报给基站，该BSR格式为Truncated BSR；如果该slot内只有1个LCG有数据需要发送，则发送Short BSR。对于Padding BSR而言，当padding bit的数量等于或大于“Long BSR+对应的subheader”的大小时，发送Long BSR。即使有多个事件触发了BSR，一个MAC协议数据单元(protocol data unit，PDU)至多也只能包含一个MAC BSR CE，其中Regular BSR和Periodic BSR的优先级要高于Padding BSR，即优先传输Regular/Periodic BSR。
4、接入网设备根据BSR为终端传输资源
当LCG具有待传输上行数据时，终端根据前述表1(或表2)确定该LCG的待传输上行数据的数据量对应的BS区间的索引值；终端向接入网设备上报该LCG的待传输上行数据的数据量对应的BS区间的索引值。进一步地接入网设备会根据该索引值，在前述表1(或表2)中确定该LCG对应的BS区间，并根据该BS区间的最大值为终端分配上行传输资源。例如，在表1中BSR表格中包括BS区间，该BS区间的数值范围为：大于38字节(Bytes)小于等于53Bytes，该BS区间的索引值为6。假设LCG1中待传输的上行数据的数据量为40Bytes，终端基于表1确定该LCG的待传输上行数据的数据量(即40Bytes)对应的BS区间索引值为6。终端向接入网设备发送BSR，该BSR中指示LCG1中待传输的上行数据的数据量对应的BS区间索引值为6。基站确定该索引值6对应BS区间的数值范围为：大于38Bytes小于等于53Bytes，并根据该BS区间中的最大值53Bytes向终端分配上行传输资源，即分配了能传输53Bytes的传输资源。
可见，通过这样的BSR发送方法请求上行传输资源时，若BS区间的涵盖范围远超过LCG中待传输数据的数据量，则接入网设备分配的资源可能会远大于终端实际需要的资源，从而造成传输资源的浪费。
本申请通过接入网设备为终端配置更加贴合终端实际需求的BS区间的方式，使得终端发送BSR请求的传输资源可以更加贴合该终端需求，从而减少传输资源的浪费。
下面结合附图对本申请提供的BSR发送方法及通信装置进行进一步介绍：
请参见图4，图4是本申请实施例提供的一种BSR发送方法的流程示意图。图4中以接入网设备和终端作为该交互示意的执行主体为例来示意该方法，但本申请并不限制该交互示意的执行主体。例如，图4中的接入网设备也可以是支持该接入网设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分接入网设备功能的逻辑模块或软件；图4中的终端也可以是支持该终端实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分终端功能的逻辑模块或软件。其中：
S401、终端接收来自接入网设备的第一配置消息，该第一配置消息配置多个缓存状态BS区间和多个索引值的一一对应关系。
需要理解的是，多个BS区间和多个索引值的一一对应关系，是指BS区间的数量和索引值的数量相同，并且一个索引值对应一个BS区间(或理解为索引值和BS区间具有一一对应关系)。
终端接收接入网设备发送的第一配置消息，该第一配置消息用于配置多个BS区间、多个索引值、以及每个索引值与BS区间之间的对应关系。其中，该第一配置消息可以为无线资源控制(radio resource control，RRC)消息。
在一个可能的实现中，该多个BS区间包括长BSR对应的BS区间和/或短BSR对应的BS区间。需要理解的是，长BSR对应的BS区间即是指long BSR格式对应的缓存大小(buffer size)表格中的BS区间，短BSR对应的BS区间即是指short BSR格式对应的缓存大小(buffer size)表格中的BS区间。换言之，第一配置消息配置的多个BS区间可以为以下三种情况的任一种。
情况一、第一配置消息配置的多个BS区间，全都为long BSR格式对应的缓存大小(buffer size)表格中的BS区间。
在这种情况下，可以认为第一配置消息只配置了发送long BSR格式的BSR时，多个BS区间与多个索引值的一一对应关系。而发送short BSR格式的BSR时，所依据的BS区间与索引值的对应关系保持不变(或理解为沿用默认的short BSR格式中BS区间与索引值的对应关系)。
情况二、第一配置消息配置的多个BS区间，全都为short BSR格式对应的缓存大小(buffer size)表格中的BS区间。
在这种情况下，可以认为第一配置消息只配置了发送short BSR格式的BSR时，多个BS区间与多个索引值的一一对应关系。而发送long BSR格式的BSR时，所依据的BS区间与索引值的对应关系保持不变(或理解为沿用默认的long BSR格式中BS区间与索引值的对应关系)。
情况三、第一配置消息配置的多个BS区间，即包括long BSR格式对应的缓存大小(buffer size)表格中的BS区间，也包括short BSR格式对应的缓存大小(buffer size)表格中的BS区间。
在这种情况下，可以认为第一配置消息不仅配置了发送long BSR格式的BSR时，多个BS区间与多个索引值的一一对应关系，也配置了发送short BSR格式的BSR时，多个BS区间与多个索引值的一一对应关系。
在另一个可能的实现中，前述对应关系(即第一配置消息配置的多个BS区间和多个索引值的一一对应关系)包括于长BSR对应的缓存大小表格中和/或短BSR对应的缓存大小表格中。
换言之，该多个BS区间和多个索引值的一一对应关系包括于长BSR对应的缓存大小表格中，即是指该第一配置消息用于配置长BSR对应的缓存大小表格，例如，该第一配置消息可以携带该长BSR对应的缓存大小表格对应的标识。
或者，该多个BS区间和多个索引值的一一对应关系包括于短BSR对应的缓存大小表格中，即是指该第一配置消息用于配置短BSR对应的缓存大小表格，例如，该第一配置消息可以携带该短BSR对应的缓存大小表格对应的标识。
或者，该多个BS区间和多个索引值的一一对应关系，包括于长BSR对应的缓存大小表 格中和短BSR对应的缓存大小表格中，即是指该第一配置消息用于配置缓存大小表格组，该第一配置消息可以携带该缓存大小表格组的标识，其中，该缓存大小表格组包括长BSR对应的缓存大小表格和短BSR对应的缓存大小表格。
在一个场景中，由于缓存中待上传的上行数据具有与业务数据相关的传输指标，因此根据不同业务数据相关的传输指标(例如，服务质量(quality of service，QoS)信息)确定第一配置消息中多个BS区间和多个索引值的一一对应关系，可以进一步地提升终端通过BSR请求的传输资源与终端实际需求资源的适配性，其中，该传输指标包括但不限于传输速率、帧率、数据帧大小相对波动范围、数据帧大小绝对波动范围中的一种或多种。需要理解的是，根据帧大小相对波动和其他传输指标(例如传输速率、帧率等)可以计算出数据帧大小绝对波动范围。例如，XR业务数据的速率为80Mbps，帧率为60FPS，数据帧大小相对波动范围为大于数据帧大小均值的80％，且小于数据帧大小均值的120％。在这种情况下，通过XR业务数据的速率和帧率可计算出该XR业务数据的数据帧大小均值为166666.7Bytes，该XR业务数据的数据帧大小的最大值为200000Bytes，该XR业务数据的数据帧大小的最小值约为133333Bytes，即数据帧大小绝对波动范围为大于133333Bytes小于200000Bytes。需要声明的是，在本申请中除非特别说明，否则本申请中所提及的帧大小波动范围均为帧大小绝对波动范围。
在这种场景的一个可能的实现中，在终端接收来自接入网设备的第一配置消息之前，终端向接入网发送上报消息，该上报消息指示数据帧大小波动范围，该数据帧大小波动范围用于对应关系的确定。其中，该上报消息为RRC消息的一种，例如该上报消息可以为用户辅助信息(user assistance information，UAI)信令。
示例性地，终端与接入网设备之间的通信协议中预先定义了2个缓存大小表格组：缓存大小表格组1和缓存大小表格组2。缓存大小表格组1包括长BSR对应的缓存大小表格1-1和短BSR对应的缓存大小表格1-2；缓存大小表格组2包括长BSR对应的缓存大小表格2-1和短BSR对应的缓存大小表格2-2。其中，缓存大小表格1-1包括255个BS区间(该255个BS区间的数值总范围为：大于等于0Bytes且小于等于100000Bytes)和1个预留BS区间(该预留BS区间的范围为：大于100000Bytes)；缓存大小表格1-2包括31个BS区间(该31个BS区间的数值总范围为：大于等于0Bytes且小于等于100000Bytes)和1个预留BS区间(该预留BS区间的范围为：大于100000Bytes)；缓存大小表格2-1包括255个BS区间(该255个BS区间的数值总范围为：大于等于0Bytes且小于等于200000Bytes)和1个预留BS区间(该预留BS区间的范围为：大于200000Bytes)；缓存大小表格2-2包括31个BS区间(该31个BS区间的数值总范围为：大于等于0Bytes且小于等于200000Bytes)和1个预留BS区间(该预留BS区间的范围为：大于200000Bytes)。在这种情况下，终端向接入网设备发送UAI信令，该UAI信令用于指示终端缓存中待传输的上行数据(例如XR业务数据)的数据帧大小波动范围为：大于等于150000Bytes小于等于200000Bytes。进一步地，接入网设备从通信协议中预先定义了2个缓存大小表格组中确定出目标缓存大小表格组，并基于该目标缓存大小表格组中包含的多个BS区间与多个索引值的一一对应关系，向终端发送第一配置消息。例如，接入网设备根据数据帧大小波动范围为大于等于150000Bytes小于等于200000Bytes，可知终端缓存中待传输的上行数据(例如XR业务数据)的数据帧的最大值为200000Bytes，则接入网设备将前述缓存大小表格组2确定为目标缓存大小表格组，并基于该缓存大小表格组2包含的多个BS区间与多个索引值的一一对应关系，向终端发送第一配置消息。
S402、终端基于该对应关系，向接入网设备发送BSR，该BSR包括目标索引值，该多个 索引值包括目标索引值。
在终端存在待发送的上行数据时，终端基于第一配置消息配置的多个BS区间与多个索引值的一一对应关系，从该多个BS区间中确定目标BS区间，并将该目标BS区间对应的索引值确定为目标索引值。进一步地，终端向接入网设备发送BSR以请求接入网设备为该待发送的上行数据配置相应的上行传输资源，终端基于该上行传输资源向接入网设备发送上行数据。
通过图4所描述的BSR发送方法，在通信协议中预先定义BS区间与索引值的多套对应关系的情况下，接入网设备可以通过向终端发送配置消息的方式，配置与终端实际需要资源更贴合的BS区间与索引值的对应关系，从而使得终端请求的传输资源更贴合终端实际需求资源，减少传输资源的浪费。
在一个场景中，由于终端的业务数据通过LCG承载，考虑到承载不同业务数据的LCG具有不同的传输指标(例如传输速率、数据帧大小波动不同)，在本申请图4所提供的BSR发送方法中，通过前述S401中第一配置消息配置的多个BS区间与多个索引值的一一对应关系可以与LCG相关联。即可以理解为，当指定LCG具有待上传的数据时，终端才会根据第一配置消息配置的多个BS区间与多个索引值的一一对应关系，向接入网设备发送BSR。
在这种场景下的一个可能实施方式中，前述S401的第一配置消息还包括LCG的标识信息。即该第一配置消息用于配置多个BS区间与多个索引值的一一对应关系、以及指定与该对应关系关联的LCG。在这种情况下，第一配置消息可以包括字段1和字段2，其中，字段1用于指示LCG标识(或字段1的数值为LCG ID)，字段2用于指示多个BS区间与多个索引值的一一对应关系。
通过实施该可能的实施方式，接入网设备可以根据不同LCG配置不同的对应关系。例如，当LCG0用于承载业务1的数据，LCG2用于承载业务2的数据的情况下，接入网设备可以向终端发送第一配置消息，第一配置消息用于配置与LCG0关联的多个BS区间与多个索引值的一一对应关系；或者，接入网设备可以向终端发送第一配置消息，第一配置消息用于配置与LCG2关联的多个BS区间与多个索引值的一一对应关系。使得终端发送BSR请求的传输资源更贴合于LCG实际需要资源，从而减少传输资源的浪费。
进一步地，在另一个可能的实现中，终端向接入网发送上行数据，该上行数据由LCG承载，该LCG与上述对应关系(即第一配置信息配置的对应关系)相关联。即可以理解为，接入网设备接收终端上报的BSR之后，根据BSR中目标索引值获得目标BS区间，并根据该目标BS区间的数值为指定LCG配置上行传输资源。进一步地，终端基于该上行传输资源，向接入网设备发送由该指定LCG承载的上行数据。
请参见图5，图5是本申请实施例提供的另一种BSR发送方法的流程示意图。图5中以接入网设备和终端作为该交互示意的执行主体为例来示意该方法，但本申请并不限制该交互示意的执行主体。例如，图5中的接入网设备也可以是支持该接入网设备实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分接入网设备功能的逻辑模块或软件；图5中的终端也可以是支持该终端实现该方法的芯片、芯片系统、或处理器，还可以是能实现全部或部分终端功能的逻辑模块或软件。其中：
S501、终端接收来自接入网设备的第一配置消息，该第一配置消息配置BS区间量化参数集合，该BS区间量化参数集合用于指示至少两类BS区间的量化粒度。
需要理解的是，长BSR格式中用8位bit指示多个BS区间的索引值，因此长BSR格式对应256个BS区间；短BSR格式中用5位bit指示多个BS区间的索引值，因此短BSR格式对应32个BS区间。第一配置消息配置的BS区间量化参数集合，该BS区间量化参数集合用于指示将长BSR格式对应的区间(即256个BS区间)分为至少两类；和/或，该BS区间量化参数集合用于指示将短BSR格式对应的区间(即32个BS区间)分为至少两类。一类BS区间的量化粒度即是指该类BS区间中每个BS区间的大小。在一个可能的实现中，第一类BS区间和第二类BS区间是该至少两类BS区间中的任意两类BS区间，其中，第一类BS区间的量化粒度不同于第二类BS区间的量化粒度。即可以理解为该至少两类BS区间采用非均匀量化的方式进行BS区间划分。通过实施该可能的实施方式，可以提升BS区间的多样性，从而提升BS区间与终端需求的适配性。
终端接收接入网设备发送的第一配置消息，该第一配置消息配置用于配置至少两类BS区间、以及每类BS区间的量化粒度(或称为每类BS区间中每个BS区间的大小)。其中，该第一配置消息可以为RRC消息。
在一个可能的实现中，该BS区间量化参数集合包括该至少两类BS区间中每类BS区间的量化粒度、以及每类BS区间在该至少两类BS区间中的比例。换言之，该BS区间量化参数集合中用于将BS区间总量划分为至少两类BS区间，每类BS区间的量化粒度，以及每类BS区间在BS区间总量中的占比。
需要声明的是，本申请所提及的BS区间总量为除去预留BS区间之外的BS区间总量，该预留BS区间可以为一个或多个，预留BS区间对应的数值范围为，大于前述BS区间总量中的最大数值的开区间。例如，预留BS区间为1个，则在长BSR格式中该BS区间总量是指除预留BS区间之外的其他255个BS区间(如索引值为0～254的BS区间)，在短BSR格式中该BS区间总量是指除预留BS区间之外的其他31个BS区间(如索引值为0～30的BS区间)。在本申请的示例中，以预留BS区间数量为1个进行示例性说明，并不能视为对本申请中预留BS区间数量的一个具体限定。
下面以预留BS区间数量为1个，该BS区间量化参数集合将长BSR格式对应的256个BS区间划分为至少两类BS区间和1个预留BS区间，进行示例性说明。
示例性地，请参见图6所示，图6为根据BS区间量化参数集合得到的BS区间的示意图。在图6中第一配置消息中的BS区间量化参数集合用于将长BSR格式对应的256个BS区间划分为两部分(即两类BS区间)和一个预留BS区间：第一部分(也可称为第一类BS区间)包括该256个BS区间的前100个BS区间(即索引值为0～99的BS区间)，第二部分(也可称为第二类BS区间)包括该255个BS区间的后155个BS区间(即索引值为100～254的BS区间)，将索引值为255的BS区间确定为预留BS区间。该BS区间量化参数集合指示了第一类BS区间的量化粒度为500Bytes，第二类BS区间的量化粒度为2000Bytes，即可以理解为第一部分BS区间中每个BS区间的大小(或称为每个BS区间的长度)为500Bytes，第二部分BS区间中每个BS区间的大小(或称为每个BS区间的长度)为2000Bytes。其中，索引值为254的BS区间的范围为：大于358000Bytes小于等于360000Bytes，该预留BS区间对应的数值范围为：大于360000Bytes。
在一个可能的实现中，该BS区间量化参数集合包括长BSR对应的BS区间量化参数集合，和/或，短BSR对应的BS区间量化参数集合。换言之，第一配置消息配置中的BS区间量化参数可以为以下三种情形的任一种。
情形一、第一配置消息配置的BS区间量化参数集合为长BSR对应的BS区间量化参数 集合。
在这种情形中，可以认为第一配置消息只配置了BSR为long BSR格式时，至少两类BS区间中每类BS区间的量化粒度，以及每类BS区间在该256个BS区间中的占比。
情形二、第一配置消息配置的BS区间量化参数集合为短BSR对应的BS区间量化参数集合。
在这种情形中，可以认为第一配置消息只配置了BSR为short BSR格式时，至少两类BS区间中每类BS区间的量化粒度，以及每类BS区间在该32个BS区间中的占比。
情形三、第一配置消息配置的BS区间量化参数集合，既包括长BSR对应的BS区间量化参数集合，也包括短BSR对应的BS区间量化参数集合。
在这种情形下，可以认为第一配置消息既配置了BSR为long BSR格式时，长BSR对应的每类BS区间的量化粒度，以及该每类BS区间在该256个BS区间中的占比；也配置了BSR为short BSR格式时，短BSR对应的每类BS区间的量化粒度，以及该每类BS区间在该32个BS区间中的占比。
在一个场景中，由于缓存中待上传的上行数据具有与业务数据对应的数据帧统计信息，因此根据不同业务数据对应的数据帧统计信息确定第一配置消息中的BS区间量化参数集合，可以进一步地提升终端通过BSR请求的传输资源与终端实际需求资源的适配性。其中，该数据帧统计信息包括但不限于数据帧大小的均值、数据帧大小的标准差、数据帧大小的最大值或数据帧大小的最小值中的一种或多种。
在这种场景的一个可能的实施方式中，在终端接收来自接入网设备的第一配置消息之前，终端向接入网设备发送上报消息，该上报消息包括数据帧统计信息，该数据统计信息用于BS区间量化参数集合的确定。其中，该上报消息为RRC消息的一种，例如该上报消息可以为UAI信令。
示例性地，终端向接入网设备发送UAI信令，该UAI信令用于指示终端缓存中待传输的上行数据(例如XR业务数据)的数据帧统计信息：该XR数据帧大小分布为服从均值为500000Bytes，标准差52500Bytes，最大值750000Bytes，最小值为250000Bytes的截断高斯分布。进一步地，接入网设备基于该XR业务数据的数据帧统计信息，确定该XR业务中数据帧大于560000Bytes的概率约小于14％。基于此，接入网设备向终端发送第一配置消息，该第一配置消息包括BS区间量化参数集合，该BS区间量化参数集合配置的BS区间包括long BSR格式对应的BS区间和short BSR格式对应的BS区间。对于long BSR格式对应的BS区间而言，接入网设备可以将除一个预留BS区间外的其他255个区间划分为两部分(或理解为划分为两类BS区间)，其中，第一类BS区间(即第一部分)占224个BS区间(即索引值为0～223的BS区间)，第一类BS区间的量化粒度(即每个第一类BS区间的大小)为2500Bytes，第二类BS区间(即第二部分)占31个BS区间(即索引值为224～254的BS区间)，第二类BS区间的量化粒度(即每个第二类BS区间的大小)为6000Bytes。对于short BS格式对应的BS区间而言，接入网设备可以将除一个预留BS区间外的其他31个区间划分为两部分(或理解为划分为两类BS区间)，其中，第一类BS区间(即第一部分)占25个区间(即索引值为0～24的BS区间)，第一类BS区间的量化粒度(即每个第一类BS区间的大小)为10000Bytes，第二类BS区间(即第二部分)占6个BS区间(即索引值为25～30的BS区间)，第二类BS区间的量化粒度(即每个第二类BS区间的大小)为50000Bytes。
S502、终端基于该BS量化参数集合，向接入网设备发送BSR，该BSR包括目标BS区间对应的索引值，该至少两类BS区间包括目标BS区间。
在终端存在待发送的上行数据时，终端基于第一配置消息中BS量化参数集合配置的至少两类BS区间，从该至少两类BS区间中确定目标BS区间，并基于该目标BS区间对应的索引值，向接入网设备发送BSR，以请求接入网设备为该待发送的上行数据配置相应的上行传输资源，终端基于该上行传输资源向接入网设备发送上行数据。
通过图5所描述的BSR发送方法，接入网设备可以通过向终端发送配置消息的方式，配置与终端实际需要资源更贴合的BS区间与索引值的对应关系，从而使得终端请求的传输资源更贴合终端实际需求资源，减少传输资源的浪费。
在一个场景中，由于终端的业务数据通过LCG承载，考虑到不同LCG承载的业务数据可能具有不同的数据帧统计信息，在本申请图5所提供的BSR发送方法中，通过前述S501中第一配置消息配置的BS区间量化参数集合可以与LCG相关联。即可以理解为，当指定LCG具有待上传的数据时，终端才会根据第一配置消息配置的BS区间量化参数集合，向接入网设备发送BSR。通过该可能的实施方式，终端不同的LCG可以关联不同的BS区间量化参数集合，可以提升终端LCG传输需求与BS区间之间的匹配度。
在这种场景下的一个可能的实施方式中，前述S501的第一配置消息还包括LCG的标识信息。即该第一配置消息用于配置BS区间量化参数集合、以及指定与该BS区间量化参数集合关联的LCG。在这种情况下，该第一配置信息可以包括字段3、字段4和字段5，其中，字段3用于指示LCG标识(或字段3的数值为LCG ID)，字段4用于指示至少两类BS区间中每类BS区间的量化粒度，字段5用于指示每类BS区间在该至少两类BS区间中的占比。
进一步地，在另一个可能的实现中，终端向接入网设备发送上行数据，该上行数据由LCG承载，该LCG与该BS区间量化参数集合相关联。即可以理解为，接入网设备接收终端上报的BSR之后，根据BSR中索引值获的目标BS区间，并根据该目标BS区间的数值为指定LCG配置上行传输资源。进一步地，终端基于该上行传输资源，向接入网设备发送由该指定LCG承载的上行数据。
