  • some unicast services have relatively small data packets. When scheduling such smaller data packets, fewer resources are used and the transmission blocks are small. Sometimes, the minimum resource unit allocated by the network cannot be fully utilized, resulting in a waste of resources. In addition, due to the small size of the data packets, on the one hand, their corresponding encoding and decoding capabilities are poor, and they are easily affected by surrounding interference factors (for example, channel conditions, or interference from larger data packets), thereby affecting transmission reliability. On the other hand, smaller data packets make the proportion of control signaling larger, and the proportion of effective data transmission is relatively low, thus affecting transmission efficiency. In some scenarios, the proportion of relatively small data packets will be relatively large, usually exceeding 50%. At this time, if If network devices use the traditional unicast method to transmit these smaller data packets, as the proportion of smaller data packets increases, the transmission efficiency and reliability of data packets will be more seriously affected.

Description

一种数据包传输的方法及装置
本申请要求于2022年11月30日提交国家知识产权局、申请号为202211527018.8、申请名称为“一种数据包传输的方法及装置”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
本申请涉及通信技术领域，尤其涉及一种数据包传输的方法及装置。
背景技术
目前，无线通信系统广泛部署，以提供各种类型的通信，例如语音业务，数据业务等。该通信系统中包括一个或多个终端设备，通过接入网连接到核心网，以实现多个通信设备之间的通信。在一些场景中，例如，新空口(new radio,NR)组播广播场景，对数据业务传输有了更高的需求。
现有技术中，网络设备可以通过单播方式向终端设备发送数据包。在执行单播通信时，网络设备可以针对每个终端设备独立调度数据包，例如根据每个终端设备的信道情况确定调制编码方式。当网络设备发送的数据包较小时，其调度该较小的数据包所需的无线资源少，如果该较小的数据包不能填满网络设备调度的最小粒度的资源，网络设备可能会通过填充一些比特来实现填满最小粒度的资源，发送不必要的填充比特会带来资源浪费和能量消耗。
因而，如何提升较小数据包的传输效率是一个值得关心的问题。
发明内容
本申请提供了一种数据包传输的方法及装置，网络设备可以将同一终端设备组的多个终端设备的数据包聚合到一个数据包中传输，然后将聚合的数据包发给终端设备，从而降低网络设备向多个终端设备中的每一个终端分别发送数据包所带来的信令开销和资源浪费，从而提升空口传输效率和传输可靠性。
第一方面，本申请提供了一种数据包传输的方法，该方法包括：确定N个终端设备中每一个终端设备的数据包，该N个终端设备为第一终端设备组中的N个终端设备，N为大于1的整数；向第一终端设备发送聚合数据包，该聚合数据包包括该N个终端设备的标识信息，以及该N个终端设备中每一个终端设备的数据包，该第一终端设备为该N个终端设备中的一个终端设备。
通过实施第一方面所描述的方法，可以实现将N个终端设备的数据包放到一个聚合数据包中进行发送，并将聚合后的数据包发送给N个终端设备，如此，可以降低向多个终端设备中的每一个终端分别发送数据包所带来的信令开销和资源浪费，从而提升空口传输效率；此外，相比单独向每个终端设备发送数据包，较大的聚合数据包的发送可以提高编码增益，从而提升空口传输可靠性。

在一种可能的实现方式中，该终端设备的标识为逻辑信道标识的全部或部分，该方法还包括：网络设备发送逻辑信道标识的全部或部分与第一终端设备的对应关系。
如此，可以在不增加终端设备实现的复杂度和额外开销的前提下，实现网络设备灵活指示终端设备的标识的目的，换句话说，可以实现网络设备指示出哪个终端设备的数据。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。
首先，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
图1为本申请实施例适用的一种通信系统示意图。如图1所示，通信系统10包括一个或多个通信装置30(例如，终端设备)经由一个或多个接入网设备20连接到一个或多个核心网设备，以实现多个通信设备之间的通信。所述通信系统例如可以支持2G,3G,4G,或5G(有时也称为new radio，NR)接入技术的通信系统，无线保真(wireless fidelity，WiFi)系统，第三代合作伙伴计划(3rd generation partnership project，3GPP)相关的蜂窝系统，支持多种无线技术融合的通信系统，或者是面向未来的演进系统。
(1)终端设备：终端设备是一种具有无线收发功能的设备，可以是固定设备，移动设备、手持设备(例如手机)、穿戴设备、车载设备，或内置于上述设备中的无线装置(例如，通信模块，调制解调器，或芯片系统等)。所述终端设备用于连接人，物，机器等，可广泛用于各种场景，例如包括但不限于以下场景：蜂窝通信、设备到设备通信(device-to-device，D2D)、车到一切(vehicle to everything，V2X)、机器到机器/机器类通信(machine-to-machine/machine-type communications，M2M/MTC)、物联网(internet of things，IoT)、虚拟现实(virtual reality，VR)、增强现实(augmented reality，AR)、工业控制(industrial control)、无人驾驶(self driving)、远程医疗(remote medical)、智能电网(smart grid)、智能家具、智能办公、智能穿戴、智能交通，智慧城市(smart city)、无人机、机器人等场景的终端设备。所述终端设备有时可称为用户设备(user equipment，UE)、终端、接入站、UE站、远方站、无线通信设备、或用户装置等等，为描述方便，本申请中将终端设备以UE为例进行说明。
(2)网络设备：例如包括接入网设备，和/或核心网设备。所述接入网设备为具有无线收发功能的设备，用于与所述终端设备进行通信。所述接入网设备包括但不限于上述通信系统中的基站(BTS,Node B,eNodeB/eNB，或gNodeB/gNB)、收发点(transmission reception point,TRP)，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。所述基站可以是：宏基站，微基站，微微基站，小站，中继站等。多个基站可以支持上述提及的同一种接入技术的网络，也可以支持上述提及的不同接入技术的网络。基站可以包含一个或多个共站或非共站的传输接收点。网络设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器、集中单元(centralized unit，CU)，分布单元(distributed unit，DU)，CU-控制面(control plane,CP),CU-用户面(user plane,UP),或者无线单元(radio unit，RU)等。CU和DU可以单独设置，或者也可以包括在同一个网元中，例如基带单元(baseband unit，BBU)中。RU可以包括在射频设备或者射频单元中，例如包括在射频拉远单元(remote radio unit，RRU)或有源天线处理单元(active antenna unit，AAU)中。
在不同系统中，CU(或CU-CP和CU-UP)、DU或RU也可以有不同的名称，但是本领域的技术人员可以理解其含义。例如，在ORAN系统中，CU也可以称为O-CU(开放式CU)，DU也可以称为O-DU，CU-CP也可以称为O-CU-CP，CU-UP也可以称为O-CU-UP，RU也可以称为O-RU。为描述方便，本申请中以CU，CU-CP，CU-UP、DU和RU为例进行描述。本申请中的CU(或CU-CP、CU-UP)、DU和RU中的任一单元，可以是通过软件模块、硬件模块、或者软件模块与硬件模块结合来实现。
网络设备还可以是服务器，可穿戴设备，或车载设备等。例如，V2X技术中的网络设备可以为路侧单元(road side unit，RSU)。以下对接入网设备以为基站为例进行说明。所述通信系统中的多个网络设备可以为同一类型的基站，也可以为不同类型的基站。基站可以与终端设备进行通信，也可以通过中继站与终 端设备进行通信。终端设备可以与不同接入技术中的多个基站进行通信。所述核心网设备用于实现移动管理，数据处理，会话管理，策略和计费等功能。不同接入技术的系统中实现核心网功能的设备名称可以不同，本申请并不对此进行限定。以5G系统为例，所述核心网设备包括：访问和移动管理功能(access and mobility management function，AMF)、会话管理功能(session management function，SMF)、或用户面功能(user plane function，UPF)等。
(3)在本申请实施例中，终端设备或网络设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。
另外，本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
(4)本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A、同时存在A和B、单独存在B的情况，其中A，B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如“A，B和C中的至少一个”包括A，B，C，AB，AC，BC或ABC。
以及，除非有特别说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一SN和第二SN，只是为了区分不同的SN，而并不是表示这两种SN的优先级或者重要程度等的不同。
(5)多播广播业务(multicast and broadcast service，MBS)是同时面向多个终端的业务，采用多播或者广播传输方式可以通过较少的资源为大量具有相同需求的用户同时提供MBS业务，例如直播业务、公共安全业务、批量软件更新业务等。
MBS的数据来自数据服务器，经由核心网设备发送到接入网设备，再由接入网设备发送给接收MBS数据的至少一个终端设备。在接入网设备向终端设备发送时，数据包通过MBS无线承载传输。一个MBS无线承载可以包括点到多点(point to multi-point，PTM)传输方式和/或点到点(point to point，PTP)传输方式。PTM传输方式是指网络设备同时向多个终端设备发送相同的数据，在采用PTM传输方式时，针对同一数据，网络设备(例如基站)发送的过程中有多个终端设备采用相同的方式对该数据进行接收。PTP传输方式是指针对某一数据，一个网络设备分别向不同的终端设备独立进行发送。
图2是本申请实施例提供的方法的系统架构的示意图，如图2所示，多播广播业务的数据可以从5G CN发送至UE1、UE2、UE3和UE4。其中，5G CN到5G RAN的传输路径可以是多播广播会话隧道。例如， 5G CN向UE1和UE2发送多播广播业务的数据，UE1和UE2的多播广播会话隧道是共享的。在空口上，RAN可以通过点到多点PTM方式向UE1、和UE2发送上述多播广播数据，即发送一份数据，两个UE均可接收。RAN也可以通过PTP方式分别向UE1和UE2发送上述多播广播数据。5G CN发送的多播广播数据也可以通过UE各自对应的协议数据单元(protocol data unit，PDU)会话发送给UE，即通过单播会话隧道的形式。例如，5G CN向UE3和UE4发送多播广播业务的数据，不同的PDU会话具有不同的PDU会话隧道。在空口上，RAN可以以单播的方式分别向UE3和UE4发送业务数据。在图2所示的架构中，5G CN到5G无线接入网(Radio Access Network，RAN)的多播广播会话也可以称为共享传送PDU会话或MBS会话(session)，包括多播会话和广播会话，传输通道可以称为共享隧道。
(6)协议栈架构：相互通信的网络设备和终端设备(例如，图1中的110和任一个终端设备、图2中的5G RAN和任一个UE)具有一定的协议层结构。例如，如图3所示的协议层架构。该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)层和物理(physics，PHY)层等协议层。其中，物理层位于最低层(层一)，MAC层、RLC以及PDCP属于第二层(层二)，RRC属于第三层(层三)。在一种实现中，PDCP层之上还可以包括业务数据适配(service data adaptation protocol，SDAP)层。
这些协议层的功能可以由一个节点实现，或者可以由多个节点实现；例如，在一种演进结构中，无线接入网设备可以包括集中单元(centralized unit，CU)和分布单元(distributed unit，DU)，多个DU可以由一个CU集中控制。CU和DU可以根据无线网络的协议层划分，例如，PDCP层及以上协议层的功能设置在CU，PDCP以下的协议层，RLC层和MAC层等的功能设置在DU等。
应该理解的是，这种协议层的划分仅仅是一种举例，还可以在其它协议层划分，例如在RLC层划分，将RLC层及以上协议层的功能设置在CU，RLC层以下协议层的功能设置在DU；或者，在某个协议层中划分，例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外，也可以按其它方式划分，例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。
(7)协议栈各层对数据包的处理：在网络设备和终端设备进行数据传输时，数据需要依次经过网络设备和终端设备上的各个层并在各个层进行相应的处理。以MBS业务的数据传输为例，如图3所示，数据首先到网络设备的SDAP层，经过PDCP层的处理以后传输到RLC层和MAC层，在MAC层经过处理之后，通过物理层发送出去，通过空口传输给终端设备。终端设备接收数据时，依次经过物理层、MAC层、RLC层、PDCP层和SDAP层对数据包依次进行对应的处理。可以将网络设备和终端设备各层对数据包的处理结合起来称为无线承载，对于每个无线承载中的每个数据，都需要经过各个层的处理。每个层都有相应的功能实体来执行相应的功能，例如，PDCP层对应PDCP实体，RLC层对应RLC实体，MAC层对应MAC实体等。其中，每个无线承载包含一个PDCP实体以及一个或者多个RLC实体，每个RLC实体对应一个逻辑信道。
需要说明的是，在本申请实施例中，数据包聚合，也可以理解为数据包级联或数据包拼接，换句话说，“聚合”、“级联”或“拼接”三者相互替换，“聚合的数据包”、“级联的数据包”和“拼接的数据包”三者可以相互替换，对此不做限制。
在一些单播应用场景中，有的单播业务的数据包较小，调度该较小的数据包时使用的资源少，传输块小，有时不能完全利用网络分配的最小资源单元，从而造成资源浪费。另外，由于数据包较小，一方面其对应的编译码能力差，容易受到周边干扰因素(例如，信道条件、或来自较大数据包的干扰)的影响，从而影响传输可靠性；另一方面，较小的数据包使得控制信令所占比例会比较大，有效数据传输比例会比较低，从而影响传输效率。在某些场景中，比较小的数据包占的比例会比较大，通常可能会超过50％，此时，如 果网络设备使用传统的单播方式来传输这些较小的数据包，随着比较小的数据包所占比例增加，数据包的传输效率和可靠性所受的影响会愈加严重。
因而，如何提升数据包较小的数据传输的效率和可靠性是一个值得关心的问题。
本申请提供一种数据包传输的方法和装置，网络设备可以对N个终端设备的数据包放到一个聚合数据包中进行发送，并将聚合后的数据包发送给N个终端设备，如此，可以降低网络设备向多个终端设备中的每一个终端分别发送数据包所带来的信令开销和资源浪费，从而提升空口传输效率；此外，通过增加确定编码方式前的数据包大小，提高编码增益，从而提升空口传输可靠性。
实施例一
图4是本申请实施例提供的一种通信方法的示意图。图4所示的方法可以由图1至图3中所示的网络设备和终端设备执行。

可选地，该N个终端设备中每一个终端设备的数据包满足至少一项：该N个终端设备为第一终端设备组中的终端设备；该N个终端设备中每一个终端设备的数据包的大小不超过第一阈值；或该N小于或等于第二阈值。应理解，每一个终端设备的数据包为网络设备发给该终端设备的数据包，即下行数据包。可选地，该数据包可以是来自其他网络设备的数据包，经由该网络设备转发给终端设备；或者，该数据包是该网络设备自己生成并发给终端设备的。这里，其他网络设备可以是核心网设备也可以是接入网设备，本申请对此不做限制。
可选地，网络设备通过执行聚合传输功能的判断，确定N个终端设备中每一个终端设备的数据包；这里，聚合传输功能的判断可以包括如下至少一项：
1)判断某一待发送数据包对应的终端设备与另一个待聚合数据包对应的终端设备是否为同一终端设备组；
2)某一待发送数据包的大小是否超过第一阈值；
3)待聚合数据包的个数是否超过第二阈值；
4)某一待发送数据包是否满足第一服务质量QoS(Quality of Service)要求；
5)判断某一待发送数据包对应的终端设备的能力信息，例如，终端设备是否支持聚合数据包的传输功能；或；
6)判断是否有对于待发送数据包进行聚合的指示信息。
可选地，第一终端设备组可以是网络设备根据某一规则进行分组的，例如，网络设备可以根据终端设备的位置，UE能力，UE的业务情况，UE版本中一种或多种来进行分组，但具体的分组方式，本申请对此不做限定。
可选地，第一阈值为协议规定或网络设备设置；可选地，第二阈值为协议规定或网络设备设置的。进一步地，若第一阈值和/或第二阈值是网络设备设置，可以是网络设备根据自身资源情况或调度能力等来设置，本申请对此不做限制。
可选地，第一服务质量QoS指标包括如下一种或多种：时延、可靠性或丢包率。可以理解，如果第一QoS指标为时延，则判断某一待发送数据包能否聚合可以是根据该待发送数据包的时延要求是否大于时延阈值；如果该待发送数据包的时延大于时延阈值，则该待发送数据包可以被聚合，反之。
可选地第一无线承载被配置了聚合功能；或者，可以是判断该数据包对应的终端设备是否支持聚合数据包传输的功能。
可选地，第一终端设备可以向网络设备发送其支持聚合数据包传输的能力；进一步地，第一终端设备可以自主向网络设备发送其支持聚合数据包传输的能力、或者可以是根据网络设备的指示或请求，向网络设备发送其支持聚合数据包传输的能力。
可选地，对于待发送数据包进行聚合的指示信息是由较高协议层(或称上层)指示给包括聚合传输功能的协议层；或者，该指示信息承载在待发送数据包的包头中。
可选地，上述N个终端设备中每一个终端设备的数据包满足以下至少一项：该N个终端设备为第一终端设备组中的终端设备；数据包的大小不超过第一阈值；该N小于或等于第二阈值；或某一待发送数据包是否满足第一服务质量QoS要求或该N个终端设备支持聚合数据包的传输功能；或有针对每一个终端设备的数据包进行聚合的指示信息。
当网络设备根据如上至少一项进行判断时，对于如上1)-6)因素的考虑先后在本申请不做限制。为便于说明聚合传输功能判断，如下以示例a和示例b进行说明：
示例a，网络设备根据1)和2)来进行判断，且对于1)网络设备根据数据包对应的终端设备组与待聚合数据包对应的终端设备是否是同一终端设备组进行判断，可以理解，网络设备根据待发送的数据包的终端设备是否是同一终端设备组和待发送给终端设备的数据包的大小是否超过第一阈值来判断；
具体地，网络设备有数据包分别发给终端设备A、终端设备B和终端设备C，发送给这三个终端设备的数据包大小依次为a、b和c，如果终端设备A和终端设备B是同一终端设备组，但与终端设备C不是一个终端设备组，第一阈值为X。此时，网络设备根据终端设备A和终端设备B是同一终端设备组可判断满足1)，网络设备需进一步判断发给终端设备A和终端设备的具体数据包是否可以聚合，如果数据包a小于第一阈值，且数据包b小于第一阈值，则网络设备可确定数据包a和数据包b可以聚合在一起；如果数据包a小于第一阈值，但数据包b大于第一阈值，则网络设备确定数据包a和数据包b不能聚合在一起。
示例b，网络设备根据1)和4)来进行判断，且对于1)网络设备根据数据包对应的终端设备组与待聚合数据包对应的终端设备是否是同一终端设备组、以及数据包是否满足第一QoS要求来进行判断；
具体地，网络设备有数据包分别发给终端设备A、终端设备B，且这两个终端设备对应于同一终端设备组，发送给这三个终端设备的数据包大小依次为a、b，且第一阈值为X。此时，一种情况下，如果数据包a和b都满足第一QoS要求：则进一步判断数据包a、b和第一阈值的关系，如果数据包a和b的大小都小于第一阈值，则网络设备可确定数据包a和b可以聚合在一起；反之，如果数据包a和b中有一个大于第一阈值，则网络设备可确定数据包a和b不可以聚合在一起。在另一种情况下，如果数据包a和b中有一个在聚合发送模式下不能满足第一QoS要求，此时，网络设备可确定数据包a和b不可以聚合在一起。
可选地，由网络设备的无线链路控制RLC层或分组数据汇聚层协议PDCP层确定N个终端设备中每一个终端设备的数据包；相应地，可以理解，如上聚合传输功能的判断可以由RLC层或PDCP层来执行，换句话说，聚合传输功能位于RLC实体或PDCP实体中。可选地，N个终端设备中每个终端设备的数据包为无线链路控制RLC层的数据包、或为分组数据汇聚层协议PDCP层的数据包。
进一步地，如果聚合传输功能位于RLC实体，对于上述6)，待发送数据包进行聚合的指示信息可以由PDCP层指示给RLC层，或者，该指示信息承载在待发送的PDCP数据包的包头中；如果聚合传输功能位于PDCP实体，对于上述6)，待发送数据包进行聚合的指示信息可以由上层指示给PDCP层，或者，该指示信息承载在待发送的上层数据包的包头中。
为便于说明聚合传输功能的执行，如下结合图5A和图5B两种协议架构示意图来说明。
图5A为本申请实施例提供的一种网络架构示意图，如图5A所示，对于终端设备UE2的一个PDCP PDU，网络设备判断是否进行聚合传输，对于不需要聚合传输的数据包，网络设备将该PDCP PDU发给对应的RLC实体处理，然后通过对应的逻辑信道，使用终端设备专用的RNTI调度进行传输；对于需要聚合传输的数据包，网络设备将该UE2的PDCP PDU发给对应的RLC实体处理，将该RLC实体处理的UE2PDCP PDU和终端设备UE1的PDCP PDU聚合到一个聚合包内，并通过公共RNTI进行调度。需要说明的是，对于UE1的PDCP PDU能否被聚合，是采用与UE2的PDCP PDU判断是否进行聚合传输相同的判断 方法，在此不再赘述。相应地，当UE2接收到数据包后，可以将用组调度接收的数据包和通过终端设备专用的RNTI调度收到的数据包在PDCP层进行去重、排序等操作。对于UE收到的聚合数据包，UE可在MAC层处理将其他终端设备的数据包丢弃，具体地，可以根据聚合数据包中包括的终端设备的标识，确定是保留自己的数据包并递交上层；或者丢弃不属于自己的数据包,针对数据包丢弃的相关处理，会在下文具体介绍，这里不再赘述。
图5B为本申请实施例提供的另一种网络架构示意图，如图5B所示，对于终端设备UE2的一个RLC PDU，网络设备判断是否进行聚合传输，对于不需要聚合传输的数据包，网络设备将该RLC PDU发给对应的实体处理，然后通过对应的逻辑信道，使用终端设备专用的RNTI调度进行传输；对于需要聚合传输的数据包，网络设备将该UE2的RLC PDU发给对应的实体处理，将处理后的UE2RLC PDU和终端设备UE1的RLC PDU级联到一个聚合包内，并通过公共RNTI进行调度。需要说明的是，对于UE1的RLC PDU能否被聚合，是采用与UE2的RLC PDU判断是否进行聚合传输相同的判断方法，在此不再赘述。相应地，当UE2接收到数据包后，可以将用组调度接收的数据包和通过终端设备专用的RNTI调度收到的数据包在RLC层进行相应操作。对于UE收到的聚合数据包，UE可在MAC层处理将其他终端设备的数据包丢弃，针对数据包丢弃的相关处理，会在下文具体介绍，这里不再赘述。

可选的，所述方法还包括：网络设备向第一终端设备发送下行控制信息，该下行控制信息用于调度该聚合数据包；进一步的，该下行控制信息承载于一个新的下行控制信息DCI格式中，例如，该DCI格式是新设计的；和/或该DCI格式是通过一个专门的无线网络临时标识RNTI加扰的。
可选的，所述聚合数据包对应的数据包包头中包括第五指示信息，该第五指示信息用于指示与该数据包包头对应的数据包为聚合数据包。
可选地，聚合数据包为媒体接入控制MAC层的数据包；进一步地，聚合数据包可以为媒体接入控制协议数据单元MAC PDU。
可选地，聚合数据包头中指示的终端设备的标识信息可以为小区无线网络临时标识、或逻辑信道标识的全部或部分、或者是网络配置的临时标识。进一步地，聚合数据包的格式可以有多种，本申请结合图6A～图6F提供的一些聚合数据包的格式的示意图来进行说明。
图6A给出了一种可能的聚合数据包的格式，如图6A所示，此聚合数据包包括第一终端设备的标识信息、第一终端设备的数据包、第k终端设备的标识信息、第k终端设备的数据包、第N终端设备的标识信息和第N终端设备的数据包；且在此聚合数据包内如上内容依次级联；需要说明的是，如果聚合数据包对应的终端个数为2，即N＝2，则此聚合数据包包括第一终端设备的标识信息、第一终端设备的数据包、第二终端设备的标识信息、第二终端设备的数据包，且在此聚合数据包内第一终端设备的标识信息、第一 终端设备的数据包、第二终端设备的标识信息、第二终端设备的数据包依次级联。
图6B给出了一种可能的聚合数据包的格式，如图6B所示，聚合数据包包括N个聚合数据单元，该N个聚合数据单元对应N个终端设备，该N个聚合数据单元中每一个聚合数据单元包括聚合数据包头和聚合数据域，其中，聚合数据包头指示N个终端设备中一个终端设备的标识信息，聚合数据域指示上述N个终端设备中一个终端设备的数据包。

可选地，如果同一个终端设备有多个数据包要放到一个聚合数据包中发送，同一终端设备对应的多个聚合数据单元可以放在一起(依次级联)，也可以不放在一起；进一步地，如果同一终端设备对应的聚合数据单元放在一起，则对应于同一终端设备的多个聚合数据单元可以共用一个聚合数据包头，换句话说，如果同一终端设备有多个数据包要放在一个聚合数据包中发送，只需在一个聚合数据包头中携带该终端设备的标识，从而节省了在聚合数据包中针对每个聚合数据包都携带终端设备的标识而带来的信令开销。进一步地，如果同一终端设备对应的聚合数据单元不放到一起发送，则各终端设备对应的聚合数据单元在聚合数据包中的位置取决于基站的实现，本申请不做限制。

图6E给出了一种可能的聚合数据包的格式，如图6E所示，聚合数据包包括N个聚合数据单元，该N个聚合数据单元对应N个终端设备，该P个聚合数据单元中每一个聚合数据单元包括聚合数据包头和一个或多个聚合数据域，其中，聚合数据包头指示N个终端设备中一个终端设备的标识信息，每个聚合数据域指示一个终端设备的一个数据包，可以理解，一个终端设备的多个数据包可以共享一个聚合数据包头。
图6F给出了一种可能的数据包的格式，如图6F所示，聚合数据包包括P个聚合数据单元，该P个聚合数据单元对应N个终端设备，该P个聚合数据单元中每一个聚合数据单元包括聚合数据包头和聚合数据域，其中，聚合数据包头指示N个终端设备中一个终端设备的标识信息，聚合数据域指示上述一个终端设备中一个数据包，可以理解，该P个聚合单元可能有多个聚合数据单元对应一个终端设备，且对应于同一终端设备的多个聚合数据单元没有放在一起发送，换句话说，图6F提供了一种聚合数据包的格式，在该格式中每个终端设备对应聚合数据单元的位置随机，具体位置取决于网络设备调度，本申请不做限制。
进一步地，聚合数据包头中指示的终端设备的标识信息为逻辑信道标识的方式有多种，如下结合方式1～方式3进行说明：
方式1：终端设备的标识信息可以通过扩展逻辑信道标识eLCH ID来指示
通过方式1指示终端设备的标识信息的方法有很多种，如下结合图7A～图7B进行说明：
如图7A所示，在此方式中，可以是使用一个预留的LCID取值(例如，35或36)来指示eLCID中包含UE标识信息，相应地，终端设备可以根据预先终端设备的标识(用一部分eLCID作为标识)，以及聚合数据包头中携带的eLCH ID域中包含的信息来确定是否有发给自己的数据包；可选地，预先获取的终端设备的标识可以是网络设备为终端设备配置。可选地，eLCH ID占用长度可为1字节或2字节。
可选地，终端设备的标识信息的长度可以小于或等于eLCID的长度；进一步地，如果终端设备的标识 信息的长度可以小于eLCID的长度，协议定好的LSB读到MSB，比如从右往左读取。
如图7B所示，在此方式中，可以是使用一个预留的LCID取值(例如，35或36)指示LCID之后包含UE标识信息，或者指示此聚合数据包头中包括UE标识信息，相应地，终端设备可以根据预留的LCID取值，以及聚合数据包头中携带的UE标识信息来确定是否有发给自己的数据包；可选地，UE标识信息可以是网络设备为终端设备配置。
方式2：可以放置在一个数据包中与所有的数据包进行级联用于指示出后续的MAC SDU分别对应哪个UE的。比如次此数据包中包含的信息可以是：UE1，UE2，UE2，UE1，UE3，分别代表后续级联的数据包分别对应UE1，2,2,1,3。此方式相比较于是方式1中复用eLCID的优势是不限制聚合的数据包使用的逻辑信道号不能使用2字节的eCLID。可选地，此数据包可以是MAC层数据包，例如MAC CE。
方式3：协议规定不同的终端设备对于需要聚合的数据包的数据无线承载使用的LCID均不同，例如通过eLCID或LCID来实现不同UE使用的LCID不同。
比如使用eLCID保证不同的UE配置的LCID都不同。UE只需要在数据包头中找到自己的eLCID就认为是自己的数据。隐式的通过eLCID体现UE信息，与方式1的区别是方式1实际用的LCID是短的LCID，方式3实际用的LCID是长的。举个例子，如果一个终端设备组中只有UE1和UE2，网络设备可以配置UE1使用的LCID为1-16，UE2使用的CID为17-32。
可选地，网络设备通过单播或组播方式，向第一终端设备发送聚合数据包。相应地，第一终端设备通过单播或组播方式，接收来自网络设备的聚合数据包。
可选地，该方法还包括如下至少一种：如果该N个终端设备的标识信息包括未知的终端设备的标识信息，第一终端设备丢弃与该未知的终端设备的标识信息对应的数据包；如果该N个终端设备的标识信息包括与第一终端设备的标识信息不匹配的第三终端标识信息，第一终端设备丢弃与该第三终端设备的标识信息对应的数据包；或如果该N个终端设备的标识信息包括第一终端设备的标识信息，第一终端设备获取该第一终端设备的标识信息对应的数据包。

可选地，动态信令中包括指示使能或去使能聚合数据包的传输的信息；进一步地，该指示使能或去使能聚合数据包的传输的信息可以是通过1比特来进行指示。例如，该信息通过1比特来进行指示，当该比特的取值被设置为“1”时，该信息指示使能聚合数据包的传输，如果该比特的取值被设置为“0”时，该信息指示去使能聚合数据包的传输；反之。再进一步地，

可选地，终端设备对应的比特位在第二指示信息中的位置可以是网络设备通过高层信令配置的，其中，高层信令包括RRC消息、DCI或MAC CE，本申请对此不做限制。可选地，该终端设备对应的比特位在第二指示信息中的位置是通过起始位置和终止位置来指示；或者是通过起始位置和占用比特数来指示。
