具体实施方式
下面结合附图及实施例对本申请再作进一步详细的描述。
为实现非5G设备接入5G网络，相关技术中提供两种方式，包括：客户终端设备(CPE，Customer Premise Equipment)实现方案和第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)与非3GPP(Non-3GPP)融合网络(3GPP and non-3GPP network convergence)实现方案，其中3GPP&Non-3GPP融合网络实现方案在3GPP R15版本开始已经进行了标准化研究。
CPE是一款无线宽带接入设备，可将5G信号转换成4G信号、NB-IoT信 号，供物联网设备或4G终端接入；或者，转换成WiFi、蓝牙、ZigBee等信号，供平板电脑、智能手机等移动终端接入；或者转光纤、网线信号，供台式机等终端通过有线接入。CPE也是一种数据回传设备，将用户视频数据通过5G信号回传到公网或者专网再传输到客户数据处理中心。CPE在面向行业的服务过程中，作为固定无线接入(FWA，Fixed Wireless Access)接入方式之一的5G CPE，面向个人市场，5G CPE可以作为移动热点设备，为手机、电脑等WiFi设备提供5G移动网络接入；面向家庭市场，5G CPE作为FWA的终端设备，可为家庭上网设备提供5G移动网络接入；面向企业市场，5G CPE可以为垂直行业部分场景下的WiFi设备提供5G网络接入服务。
当前，为了推动CPE在行业市场上的快速发展，中国通信标准化协会(CCSA)也在推进CPE在信号制式转换、CPE防水防尘等级、CPE上下行射频通道规格、无线通信功能支持特性等方面面向行业增强。比如现在CCSA的无线通信技术工作委员会TC5(Technical Committee 5，第五技术工作委员会)里的《5G移动通信网用户驻地设备(CPE)技术要求》，该技术要求中指出5G CPE设备是指交直流电源供电，采用5G无线接入技术，承担将5G无线通信数据与其他非蜂窝通信(如以太网、WLAN、蓝牙、ZigBee、NFC、红外、行业用通信接口等)数据之间的转换功能，以支持仅具备其他非蜂窝通信能力的设备连接到5G无线通信网的用户驻地设备；主要解决两个问题：第一，在3GPP所定义的CPE技术框架下，为面向行业选取必要的功能特性组合；第二，制定CPE所支持的物联网接入协议及方法，比如是否需要支持WiFi、蓝牙、NB-IoT等通信方式，以及不同通信制式的接入认证方式等。因此，基于现有3GPP终端(UE)协议实现的5G CPE，对接入到CPE的业务系统或者网络制式的上行数据调度方式依然遵循当前标准所定义的流程，如图1所述。
5G CPE连接多个仅具备其他非蜂窝通信能力的终端，用于将该终端的数据发送到基站。每当该仅具备其他非蜂窝通信能力的终端需要发送数据时，该终端通过5G CPE向基站发送调度请求(SR，Scheduling Request)，以向5G基站侧询问上行链路授权(UL Grant，Uplink Grant)，并上报缓存状态报告(BSR， Buffer Status Report)。基站侧通过DCI 0_0或DCI 0_1消息中向终端回复上行链路授权。此后，终端开始发送上行数据。根据业务信道的不同，终端可能建立大量的无线承载，如果为每一个逻辑信道上报一个缓存状态报告(BSR)，会带来大量的信令开销。为了避免这种开销，通过引入了逻辑通道组(LCG，Logical Channel Group)的概念，并将每个逻辑信道放入一个LCG(共8个)中。终端基于LCG来上报BSR，而不是为每个逻辑信道上报一个BSR。
BSR通过MAC层的BSR媒体接入控制(MAC，Medium Access Control)控制单元(CE，Control Element)上报，主要包含短(Short)BSR格式(固定大小)、长(Long)BSR格式(可变大小)、短截(Short Truncated)BSR格式(固定大小)、长截(Long Truncated)BSR格式(可变大小)；同时，BSR包含LCG身份标识号(ID，Identity document)(采用Short BSR和Short Truncated BSR)或者LCGi(采用Long BSR和Long Truncated BSR)、缓冲区大小两部分信息，其中，LCG ID表示逻辑信道组ID字段，长度为3位；LCGi该字段指示逻辑信道组i的缓冲区是否存在数据；缓冲区大小字段标识逻辑信道组LCG ID或者LCGi可用的数据总量，其中Short BSR格式和Short Truncated BSR格式的该字段的长度是5比特；Long BSR格式和Long Truncated BSR格式的该字段的长度是8比特。对于Long BSR格式和Long Truncated BSR格式，缓冲区大小字段按升序包含在LCGi中。
从上述的上行调度流程可知，针对每一个所定义的逻辑信道(广播控制信道(BCCH，Broadcast Control Channel)、寻呼控制信道(PCCH，Paging Control Channel)、公共控制信道(CCCH，Common Control Channel)、专用控制信道(DCCH，Dedicated Control Channel)、专用业务信道(DTCH，Dedicated Transmission Channel))最多只有一个BSR上报给基站，基站收到BSR后，通过缓存大小(Buffer Size)域得到一个索引(index)，再用这个index映射得到终端在该逻辑信道上真正需要发送的“近似”上行数据量。因此在此机制下，对于某一个终端的上行数据传输逻辑信道DTCH而言，实际上只能上报一个Buffer数据到基站侧。

在当前CPE普遍存在的行业应用场景中，CPE被用作5G信号到其他信号制式(WiFi、光纤、有线、HDMI、蓝牙等)的转换网关，以满足不支持5G接入的行业设备能够接入到5G网络中，以及接入到基于网络切片技术构建的、行业专属服务的专用网络中；但在实际的业务匹配过程中，接入到CPE的网络呈现多样化和复杂化(WiFi、光纤、有线、HDMI、蓝牙等)、业务端到端QoS保障的差异化需求等特点，如下图3所示，提供几种业务场景：
业务场景1：通过WiFi接入CPE的业务，普遍承载的是对网络质量(吞吐量、端到端时延、服务级别协议(SLA，Service Level Agreement)保障等)要求不高的业务，比如办公自动化(OA，Office Automation)类应用、公众类应用等。
业务场景2：通过光纤或者有线接入CPE的业务，通常是对网络质量(吞吐量、端到端时延、SLA保障等)要求较高的业务，比如医疗影像设备、医疗超声设备以及其他医学检测或监控类设备等。
业务场景3：通过蓝牙、罗拉(LORA)等接入CPE的业务，是对时延要求很高但对吞吐量要求不高的业务，比如定位类业务、设备管控类业务等。这类业务需要实时更新位置信息或者接受指令，以保障业务执行的准确性与快速性。
为了使能CPE可以有效支持上述所提及的三种场景(业务场景1、业务场景2、业务场景3)，需要让基站侧能够识别接入到CPE的不同业务类型或者接入网络类型，以及所接入的业务或者网络对端到端传输质量的要求(传输吞吐量、传输时延、传输SLA等)；从而保障在上行数据的传输过程中，保障所接 入到CPE的业务或者网络性能的差异化要求。而基于现有3GPP终端(UE)协议实现的5G CPE而言，从技术上存在以下两个问题：
1、基站无法识别到CPE后端接入的网络类型或者业务类型：如上所述，基站从CPE上报的一个Buffer信息，无法从该Buffer信息判断出该CPE所接入的网络类型或者业务类型，以及传输性能的差异化要求。
2、CPE上报的Buffer信息没有反映其后端接入网络类型或者业务类型的传输性能差异化需求：在现有的CPE数据转发实现机制中，接入到CPE后端的多类型业务或者网络所承载的数据，无差异化或者无序的填入CPE上报的Buffer信息中。
上述问题会导致CPE后端接入的多制式网络或者业务类型的差异化网络能力传输要求无法有效传递到基站侧，最终导致业务端到端性能无法保障。比如，医疗影像设备通过光纤接入到CPE，同时有视频娱乐类业务通过WiFi网络接入到CPE，并且医疗影像设备与娱乐类业务均处于满负荷传输阶段，在该种场景下，如果采用3GPP现有定义的上行调度Buffer传输机制，该Buffer会同时且无序的接收来自医疗影像设备和娱乐类业务的数据(比如先到先填满)，从而导致基站对这两种业务的调度无任何差异化的对待，最终可能由于在上行信道中传输了大量的娱乐类业务数据(来自于WiFi连接)，导致医疗影像云的传输质量严重下降，无法满足其诊疗的需求等。

通过不同的指示，业务数据可以包括：一个或多个第一数据。
不同第一数据设定不同优先级是考虑到业务需求，例如，对于时延要求低的业务的第一数据(如常规管理数据，可以每隔一段时间更新)，优先级可以设定比较低，而对于时延要求高的业务的第一数据(如远程手术的第一数据)，优先级应设定高。
在一些实施例中，所述第三指示通过组合索引的形式表示；

其中，不同编号可以对应不同的业务类型和/或网络类型，也即，第二设备可以根据不同的编号了解每种第一数据对应的业务类型和/或网络类型，如此，第二设备针对不同的第一数据进行调度，实现了在上行的数据传输过程中，有效保障CPE后端接入的(即CPE与终端之间的)网络和/或业务的传输性能差异化需求。
具体来说，第二设备已知第一设备上的多个第一数据的编号，获取方式可能为：第一设备给第二设备上报，或在第一设备和第二设备双方都遵循的规范(协议)中已明确定义编号规则；

半静态配置：适用于业务比较稳定、第一数据规律性强的场景，比如办公场景，在此类场景下，第二设备不需要针对每次上传的第一数据调度下发第二信息，半静态配置方式下第二信息可通过RRC信令携带；
动态配置：适用于业务场景动态变化、第一数据规律性差的场景，比如物 联网场景，在此类场景下，第二设备需要频繁调整第二信息并下发甚至针对每次上传的第一数据调度下发第二信息，动态配置方式下第二信息可通过MAC-CE信令或者DCI信令携带。
在一些实施例中，所述接收来自所述第二设备的RRC信令，包括：

本申请实施例对所述第一设备、所述第二设备的名称不作限定，只要能实现所述第一设备、所述第二设备的功能即可。

向所述第一设备发送第二信息；所述第二信息用于指示所述第一设备发送所述至少一个第一数据的第一发送策略。
其中，所述第一数据可以理解为一种第一设备侧的缓存数据(Buffer)，所述第一数据的缓存状态也可以描述为缓存状态报告(BSR，Buffer Status Report)；
所述第一信息包括至少一个第一数据的缓存状态，所述第一信息也可以描述为多缓存状态报告(M-BSR，Multiple Buffer Status Report)。
所述第一设备(如CPE)可以向第二设备(如基站)上报所述第一设备所连接的多个网络和/或多个业务的第一数据的缓存状态(即Buffer Status Report，包含每个第一数据的可传输到第二设备的数据量信息)，以帮助基站根据所述第一设备所连接的网络的能力完成发送策略的制定，并下发到第一设备。
其中，所述第二信息由第二设备确定并发送给第一设备；所述第二信息用于指示所述第一设备发送第一数据的第一发送策略，也即，第二设备指示第一设备发送第一数据的顺序和/或方式。
所述第二信息用于针对多个第一数据的调度，所述第二信息也可也描述为多缓存调度指示(M-BSI，Multiple Buffer Scheduling Index)。在第二设备向第一设备的下行信令中，第二设备可以通过第二信息指示第一设备对多个第一数据或者通道的调度策略，以保障接入到第一设备的多个网络或者业务的端到端性能满足SLA要求。
在一些实施例中，所述第二信息，包括以下其中之一：
第一指示；所述第一指示用于指示传输所述至少一个第一数据，及单次传输单个第一数据；
第二指示；所述第二指示用于指示所述至少一个第一数据中每个所述第一数据的传输优先级，及单次传输单个第一数据；
第三指示；所述第三指示用于指示传输所述至少一个第一数据，及单次传 输的多个第一数据的组合；
第四指示；所述第四指示用于指示所述至少一个第一数据中每个所述第一数据的传输比例，及单次传输的多个第一数据。
这里，第二信息可以指示多种发送策略，即第一指示、第二指示、第三指示、第四指示。
第一指示可以理解为一种直接指示方式，直接指示第一设备在上行数据传输过程中，调度哪一个待传第一数据进行传输；在该种模式下，第一设备一次只传输一个第一数据。
第二指示可以理解为一种优先权指示方式，指示第一设备在上行数据传输过程中，多个待传第一数据的传输优先级；在该种模式下，第一设备一次只传输一个第一数据，同时只有当高优先级的第一数据传输完成或者为空的时候，才能传输低优先级的第一数据。

在一些实施例中，每个所述第一数据对应不同的业务类型和/或不同的网络类型。
第二设备针对第一数据对应的不同的业务类型和/或网络类型进行调度，可以满足不同网络的第一数据的差异化需求。
实际应用时，为了实现针对第一设备上第一数据的调度，第一设备可以预 先将第一数据的信息(如编号、传输优先级等)发送给第二设备。
对于第一指示、第三指示、第四指示，第一设备、第二设备可以预先知道第一数据的编号、传输优先级；因此，只需指示每次传输一个第一数据、每次传输多个第一数据的组合、或者每次传输第一数据的数据量的传输比例，第一设备可以根据自身已知的优先级，结合指示内容进行传输。
对于第二指示，第二设备可以预先知道第一数据的编号、传输优先级，但第一设备自身不知道各第一数据的传输优先级；因此，第二指示需要指示各第一数据的传输优先级，即传输优先级由第二设备配置并告知第一设备。
实际应用时，对于第一指示、第三指示、第四指示的实现，第一设备、第二设备需要预先知晓传输优先级；即第二设备已知第一设备上的多个第一数据的传输优先级，获取方式可能为：第一设备给第二设备上报，或在第一设备和第二设备双方都遵循的规范(协议)中明确定义。
基于此，在一些实施例中，所述方法还包括以下至少之一：
基于预设的协议确定每个所述第一数据的传输优先级；
接收所述第一设备发送的每个所述第一数据的传输优先级。
实际应用时，对于每个第一数据的业务类型和/或网络类型可以预先告知第二设备侧，以使第二设备保障接入到第一设备的多个业务类型和/或网络类型的端到端性能满足SLA要求。

基于预设的协议确定每个所述第一数据的编号。
这里，不同编号可以对应不同的业务类型和/或网络类型，也即，第二设备可以根据不同的编号了解每种第一数据对应的业务类型和/或网络类型，如此，第二设备针对不同的第一数据进行调度，实现了在上行的数据传输过程中，有效保障CPE后端接入的(即CPE与终端之间的)网络和/或业务的传输性能差异化需求。
具体来说，第二设备已知第一设备上的多个第一数据的编号，获取方式可 能为：第一设备给第二设备上报，或在第一设备和第二设备双方都遵循的规范(协议)中已明确定义编号规则。
在一些实施例中，所述第一设备连接至少一个终端；
每个所述终端通过相同或不同的网络连接所述第一设备；
每个所述终端向所述第一设备发送相同或不同的业务类型的第一数据。
所述网络的网络类型可以包括：无线通信技术(Wi-Fi，Wireless Fidelity)、蓝牙(Buletooth)、紫蜂(Zigbee)、红外网络、窄带物联网(NB-IoT，Narrow Band Internet of Things)、远距离无线电(LoRa,Long Range Radio)、以太网(Ethernet)。

需要说明的是，每个第一数据携带对应的编号，每个编号对应不同的业务类型和/或网络类型。也即第二设备可以根据编号确定第一数据的业务类型和/或网络类型。
对于第二设备已知第一设备侧的各第一数据的传输优先级的情况，第二设备可以根据每个所述第一数据的缓存状态、传输优先级、业务类型和/或网络类型，结合所述网络状态，确定传输多个第一数据的组合方式和/或第一数据的传输比例等(如得到第三指示和第四指示)，即确定第二信息。
需要说明的是，对于具体按照哪种规则进行第一数据的组合、传输比例的划分、传输优先级的设定等可以基于实际应用的情况进行确定，对于其具体采用的规则不做限定。
在一些实施例中，所述第一信息的字节长度低于第一阈值；
所述第二信息的字节长度低于第二阈值。
具体来说，本申请实施例中可以对第一信息、第二信息的字节长度进行限定，如可以是2bit、4bit、6bit等，具体根据实际应用需求设定，也即根据实际应用需求设定第一阈值、第二阈值，以提高传输效率。
在一些实施例中，所述第二信息的配置方式包括以下至少之一：半静态方式、动态方式。
具体来说，第二信息的传输方式可以分为半静态配置、动态配置方式两种：
半静态配置：适用于业务比较稳定、第一数据规律性强的场景，比如办公场景，在此类场景下，第二设备不需要针对每次上传的第一数据调度下发第二信息，半静态配置方式下第二信息可通过RRC信令携带；

具体地，半静态配置方式下，第二信息的下发触发方式可以为固定时间下发、周期性下发、非周期性下发等几种：
固定时间下发：指在固定时间点下发，比如在每天的9:00和18:00分别下发不同的第二信息进行调度指示；
周期性下发：指按照预设的固定周期下发，该周期可由第二设备决定或由网络配置；
非周期性下发：指根据业务需求触发的非周期性下发，比如针对突发的业务场景临时下发特定的第二信息进行调度指示。
以下几种应用实施例对第一信息、第二信息、第一设备、第二设备、第一 数据进一步说明。其中，第一信息可以描述为M-BSR，第二信息可以描述为M-BSI，第一设备可以为CPE，第二设备可以为基站，第一数据可以为Buffer。
一种应用实施例，采用一种直接指示(相当于上述第一指示)方式，直接指示第一设备在上行数据传输过程中，调度哪一个待传第一数据进行传输；在该种模式下，第一设备一次只传输一个第一数据。即第二信息包括第一指示。
直接指示方式的实现的预置条件可以如下：
1)、基站已知CPE上多个第一数据(第一数据为CPE侧的Buffer)的编号，获取方式可能为：CPE给基站上报，或在CPE和基站双方都遵循的规范(3GPP标准协议等)中已明确定义编号规则，或由网络管理员在基站侧配置；
2)、CPE已知自身多Buffer的传输优先级；且基站也已知CPE上多Buffer的业务优先级，获取方式可能为：CPE给基站上报，或在CPE和基站双方都遵循的规范或协议(如3GPP标准协议等)中已明确定义，或由网络管理员在基站侧配置；
这里，CPE相当于一个中间人、网关，用于对不同网络连接到CPE的信号统一转为5G信号给基站。
3)、基站与CPE之间的信令(如第一信息、第二信息)长度要求较严格，需采用占用信令长度较短的信令格式；
4)、基站与CPE之间的业务数据通道资源受限，一次只能上传一个第一数据。
在该种模式下，M-BSI的实现方式可以采用Buffer ID(即第一数据的标识)指示、Buffer Bitamp(位图)指示等多种实现方案。举例说明，假设当前CPE端有4个待传第一数据(Buffer)，分别为Buffer A、Buffer B、Buffer C、Buffer D。两种技术方案实现如下：
当采用Buffer ID指示方法时，M-BSI需要2bit来指示CPE调度哪一个Buffer，如果M-BSI＝“00”则表示调度Buffer A；如果M-BSI＝“01”则表示调度Buffer B；如果M-BSI＝“10”则表示调度Buffer C；如果M-BSI＝“11”则表示调度Buffer D。
以下表1所示为CPE侧有4个Buffer场景下，采用基于Buffer ID的指示方式。
Figure PCTCN2022134770-appb-000001
表1
当采用Buffer Bitmap指示时，在假设当前CPE端有4个待传Buffer的情况下，需要4bit来进行表示，其中，每一bit对应一个Buffer是否被调度。当该Buffer对应的bit为1时，表示该buffer被调度进行数据传输；当该Buffer对应的bit为0时，表示该buffer不被调度。比如如果M-BSI＝“0001”，则表示调度Buffer A；如果M-BSI＝“0010”，则表示调度Buffer B；如果M-BSI＝“0100”，则表示调度Buffer C；如果M-BSI＝“1000”，则表示调度Buffer D；
表2所示为CPE侧有4个Buffer场景下，采用基于Buffer bitmap的指示方法。
Figure PCTCN2022134770-appb-000002
表2
另一种应用实施例，采用一种优先权指示(相当于上述第二指示)方式，指示第一设备在上行数据传输过程中，多个待传第一数据的传输优先级；在该种模式下，第一设备一次只传输一个第一数据，同时只有当高优先级的第一数据传输完成或者为空的时候，才能传输低优先级的第一数据。即第二信息包括第二指示。
优先权指示方式下，基站向CPE配置多Buffer的传输优先级，CPE根据各Buffer的传输优先级，决定上行业务数据信道上传输的Buffer。在该种指示方式下，可以采用：Buffer优先级直接指示方式、Buffer优先级间接指示方式。
A)、Buffer优先级直接指示方式。
Buffer优先级直接指示方式的预置条件可以如下：
1)、基站已知CPE上多Buffer的编号，获取方式可能为：CPE给基站上报，或在CPE和基站双方都遵循的规范中已明确定义编号规则，或由网络管理员在基站侧配置；
2)、基站已知CPE上多Buffer的传输优先级，但CPE本身不知其Buffer的传输优先级，需要基站为CPE下发优先级信息；或者，CPE上多Buffer的优先级动态变化，需要基站为CPE动态下发优先级信息；
3)、基站与CPE之间的信令长度要求较宽松；
4)、基站与CPE之间的业务数据通道资源受限，一次只能上传一个Buffer的数据。
举例说明，假设当前CPE端有4个待传Buffer，分别为Buffer A、Buffer B、Buffer C、Buffer D，在下行信令中会直接指示Buffer描述信息与该Buffer对应的优先级。如表3所述，第二信息(M-BSI)包括：Buffer描述信息和Buffer优先级。其中，Buffer描述信息可以为Buffer ID、Buffer字符串表述等多种方式；Buffer优先级可以为数字描述、可以为字符串描述等多种表述方式。比如在下行的信令中，M-BSI为“0,1；1,2；2,3；3,4”则表示Buffer A具有最高优先级，Buffer D具备最低优先级；同理M-BSI指示信息为“Buffer A,1；Buffer B,2；Buffer C,3；Buffer D,4”。
表3所示为CPE侧有4个Buffer场景下，采用基于Buffer优先级直接指示的指示方法的表格。

Figure PCTCN2022134770-appb-000004
表3
B)、Buffer优先级间接指示方式。
Buffer优先级间接指示方式的预置条件可以如下：
1)、基站已知CPE上多Buffer的编号，获取方式可能为：CPE给基站上报，或在CPE和基站双方都遵循的规范中已明确定义编号规则，或由网络管理员在基站侧配置；
2)、基站已知CPE上多Buffer的传输优先级，但CPE本身不知其Buffer的传输优先级，需要基站为CPE下发优先级信息；或者，CPE上多Buffer的优先级动态变化，需要基站为CPE动态下发优先级信息；
3)、基站与CPE之间的信令长度要求较严格，需采用占用信令长度较短的信令格式；
4)、基站与CPE之间的业务数据通道资源受限，一次只能上传一个Buffer的数据。
举例说明，假设当前CPE端有4个待传Buffer，分别为Buffer A、Buffer B、Buffer C、Buffer D。在下行信令中会间接指示Buffer描述信息与该Buffer对应 的优先级。如表4所述，M-BSI只包含Buffer描述信息，其中Buffer描述信息的先后顺序决定了buffer被调度的优先级。比如在下行的信令中，M-BSI为“0,1,2,3”则表示Buffer A具有最高优先级，Buffer D具备最低优先级；同理M-BSI指示信息为“Buffer A,Buffer B,Buffer C,Buffer D”。
表4所示为CPE侧有4个Buffer场景下，采用基于Buffer优先级间接指示的指示方法。
Figure PCTCN2022134770-appb-000005
表4
再一种应用实施例，采用一种多Buffer组合指示(相当于上述第三指示)方式，指示第一设备在上行数据传输过程中，调度哪几个待传第一数据进行传输；在该种模式下，第一设备一次可以传输多个第一数据，同时只有当高优先级的第一数据传输完成或者为空的时候，才能传输低优先级第一数据。即第二信息包括第三指示。
多Buffer组合指示方式的预置条件可以如下：
1)、基站与CPE之间有由共同遵循的规范定义的指示多Buffer组合信息的列表信息；
2)、CPE已知自身多Buffer的传输优先级；且基站也已知CPE上多Buffer的业务优先级，获取方式可能为：CPE给基站上报，或在CPE和基站双方都遵循的规范或协议(如3GPP标准协议等)中已明确定义，或由网络管理员在基站侧配置；
3)、基站与CPE之间的信令长度要求较严格，需采用占用信令长度较短的信令格式；
4)、基站与CPE之间的业务数据通道资源较宽裕，一次可上传多个Buffer的数据。
在该模式下，CPE已知多个Buffer的传输优先级，基站通过下行信令(M-BSI)间接指示组合描述信息，以指示CPE需要上报的哪几个Buffer数据，并按照Buffer已知的传输优先级上报数据。
如表5所示，M-BSI包含Buffer组合描述信息，用ID表述，指示Buffer排列组合号，所有排列组合形成基站与CPE都遵循的一个列表。例如，当前CPE有4个待传Buffer，分别为Buffer A、Buffer B、Buffer C、Buffer D，对应组合有15种，长度占据4bit，如表6所示，当M-BSI＝0，表示发送Buffer组合为{Buffer A}的数据；当M-BSI＝5，表示发送Buffer组合为{Buffer A、Buffer C}的数据；当M-BSI＝14，表示发送Buffer组合为{Buffer A、Buffer B、Buffer C、Buffer D}的数据。

还一种应用实施例，采用一种多Buffer合并指示(相当于上述第四指示)方式，指示第一设备在上行数据传输过程中，每个待传第一数据Buffer的数据量占比或数量；在该种模式下，第一设备一次可以传输多个第一数据。即第二信息包括第四指示。
多Buffer合并指示方式包括：多Buffer合并直接指示、多Buffer合并间接指示。
A)、多Buffer合并直接指示方式。
多Buffer合并直接指示方式的预置条件可以如下：
1)、CPE已知自身多Buffer的传输优先级；且基站已知CPE上多Buffer的传输优先级，获取方式可能为：CPE给基站上报，或在CPE和基站双方都遵循的规范或协议(如3GPP标准协议等)中明确定义，或由网络管理员在基站侧配置；
2)、基站与CPE之间的信令长度要求较宽松；
3)、基站与CPE之间的业务数据通道资源受限，每次可上传约1个Buffer或由基站指定的数据量。
该模式下，基站向CPE配置上行多Buffer的传输数据量。在该种指示方式下，M-BSI包括Buffer描述信息和Buffer数据量。其中Buffer描述信息可以为Buffer ID、Buffer字符串表述等多种方式；Buffer数据量可以为绝对值、百分比等多种表述方式。比如，CPE侧有4个Buffer(分别为Buffer A、Buffer B、Buffer C、Buffer D)场景下，在下行的信令中，M-BSI为“0,10％；1,20％；2,30％； 3,40％”则表示Buffer A传输10％数据量，Buffer B传输20％数据量，Buffer C传输30％数据量，Buffer D传输40％数据量；同理M-BSI指示信息为“Buffer A,10％；Buffer B,20％；Buffer C,30％；Buffer D,40％”。
表7所示为基于多Buffer合并直接指示的指示方法。
Figure PCTCN2022134770-appb-000007
表7
B)、多Buffer合并间接指示方式。
多Buffer合并间接指示方式的预置条件如下：
1)、CPE已知自身多Buffer的传输优先级；且基站已知CPE上多Buffer的传输优先级，获取方式可能为：CPE给基站上报，或在CPE和基站双方都遵循的规范或协议(如3GPP标准协议等)中已明确定义，或由网络管理员在基站侧配置；
2)、基站与CPE之间有由共同遵循的规范定义的指示多Buffer数据量占比的码本信息；
3)、基站与CPE之间的信令长度要求较严格，需采用占用信令长度较短的 信令格式；
4)、基站与CPE之间的业务数据通道资源受限，每次可上传约1个Buffer或由基站指定的数据量。
在该模式下，基站通过码本的方式向CPE配置上行多业务数据buffer的传输数据量。该指示方式下，一个M-BSI ID即可表示多个Buffer在上行数据传输过程中的数据量占比与分配情况，如下式(1)所示：
M-BSI＝index{P 1,P 2,......,P N}       式(1)
上述(1)中，P n,n∈{1,2,...,N}表示多个Buffer的预分配比例，N表示具备N个码本组合，且P n具备以下属性，如下式(2)所示：
Figure PCTCN2022134770-appb-000008
上式(2)中，P n表述M个buffer所对应的分配比例，例如P n,1表示Buffer A所对应的上传数量百分比，P n,2表示Buffer B所对应的上传数量百分比，P n,M表述Buffer M所对应的上传数量百分比。
例如，比如当CPE上支持3个buffer分别是Buffer A、Buffer B、Buffer C，同时假设码本集合为8，按照式(1)与式(2)可构造出的码本集合如下表所示，特别注意的是本专利不对如何生成该码本做进一步的说明。
表8为基于多Buffer合并间接指示的信息表
  P0 P1 P2 P3 P4 P5 P6 P7 P8
对应Buffer A的分配比例 1 0 0 1/3 0.2 0.7 0.34 0.4 0.5
对应Buffer B的分配比例 0 1 0 1/3 0.5 0.1 0.53 0.4 0.2
对应Buffer C的分配比例 0 0 1 1/3 0.3 0.2 0.13 0.2 0.3
表8
表8中，每列代表每个Buffer的上传数据比例。举例说明，从表1中可以看出，当M-BSI＝0时，Buffer编码码本为[1 0 0]，则表示只发送Buffer A的数据；当M-BSI＝3时，Buffer编码码本为[1/3 1/3 1/3],则表示Buffer A/B/C各占发送数据的1/3；当M-BSI＝5时，Buffer编码码本为[0.7 0.1 0.2]，表示Buffer A发送数据占70％，Buffer B发送数据占10％，buffer C发送数据占20％。
在具体的实现过程中，基站通过在下行信令中传输Buffer编码的索引给CPE，CPE侧根据预先配置或者内置的码本集合，并结合基站传输的码本索引获取多个上行业务Buffer的数据分配比例，从而实现最小开销情况下的最优Buffer数据调度方法。
图7为本申请应用实施例提供的一种通信方法的示意图；如图7所示，所述方法包括：
步骤701、CPE向基站发送第一信息；
所述第一信息也即多Buffer状态信息(M-BSR)，这里，CPE向基站上报的M-BSR包括：CPE所连接的多个网络或者业务的上行数据的缓存状态，以帮助基站根据所连接网络的能力快速完成调度策略的制定，并下发到CPE。
步骤702、基站向CPE发送第二信息；
所述第二信息也即多Buffer调度指示(M-BSI)，在下行信令中，通过M-BSI指示CPE上的多Buffer或者通道的调度策略，以保障接入到CPE的多个网络或者业务的端到端性能满足SLA要求。
步骤703、CPE传输上行业务数据；
应用时CPE根据第二信息确定第二跳网络的数据的调度策略，CPE完成第二跳网络数据的组装与合并，将合并后的业务数据按照资源调度指示，完成从CPE到基站的数据传输过程。
这里，所述合并后的业务数据，包括：至少一个Buffer。其中，业务数据可以包括一个Buffer，即可以是一次上传一个Buffer；也可以是对多个Buffer进行组装和合并，即业务数据包括多个Buffer。
