为了便于理解本申请实施例,下面对本申请实施例所涉及到的基本流程以及基本概念进行简单说明。应理解,下文所介绍的基本流程以及基本概念并不对本申请实施例产生限定。
5G的主要应用场景为:增强移动超宽带(eMBB,Enhanced Mobile Broadband)、低时延高可靠通信(URLLC,Ultra Reliable Low Latency Communications)、大规模机器类通信(mMTC,massive Machine Type Communications)。其中,eMBB以用户获得多媒体内容、服务和数据为目标,其需求增长十分迅速;由于eMBB可能部署在不同的场景中,便如室内,市区,农村等,其能力和需求的差别也比较大,所以必须结合具体的部署场景详细分析。URLLC的典型应用包括:工业自动化,电力自动化,远程医疗操作(手术),交通安全保障等。mMTC的典型特点包括:高连接密度、小数据量、时延不敏感业务、低成本和长使用寿命等。
网络编码是一种融合了路由和编码的信息交换技术,它的核心思想是在网络中的各个节点上对各条数据流上收到的信息进行线性或者非线性的处理,然后转发给下游节点,中间节点扮演着编码器或信号处理器的角色
具体地,中间节点可以将多条路径上的数据位组(x,y)通过逻辑运算处理(如异或处理)合成一组数据位组(xXORy)进行发送,接收端终端在提前获知到x和/或y的前提下,都可以通过逻辑运算处理解出(xXORy)内的各路数据位组(x,y)。此处,支持的NC的数据流数目或数据包处理数目为2.
网络编码作为一种可达网络容量的新技术,在项目关注的两种场景均可能存在较大增益:
(1)针对点对点多路复制传输,现有的分路单独传输增益受限于最坏路径情况,而网络编码传输可以适配调整数据流向,使得传输主要取决于最好路径情况。
(2)针对多跳网络传输,简单转发策略会使传输速率随着丢包率的升高指数下降,网络编码基本可达网络容量。
为了保障传输速率,就需要5GS的QoS(Quality of Service,服务质量)机制。如图2所示,在移动通信网络中,为了能够传输用户面数据(即应用/服务层),需要建立一个或多个QoS Flow(数据流),而不同的数据流对应不同的QoS参数,如图2所示,可以基于QoS规则进行上行(UL)数据包到QoS流的映射,并标记为QoS流,对每个数据流中的数据包标记对应的QoS流ID。作为通信质量(Communication quality)的重要衡量标准,通常使用QoS参数来指示QoS Flow的特征,QoS参数可以包括但不限于:5QI(5G QoS Identifier,5G QoS指示符)、ARP(Address Resolution Protocol,地址解析协议)、GFBR(Guaranteed Flow Bit Rate,保证流比特率)、MFBR、Maximum Packet Loss Rate(最 大丢包率)(UL,DL)、端到端PDB(Private DataBase专用数据库)、AN-PDB、Packet Error Rate(包错误率)、Priority Level(优先级)、Averaging Window(平均窗口)、Resource Type(资源类型)、Maximum Data Burst Volume(最大数据突发量)、UE-AMBR(Aggregate Maximum Bit Rate,总计最大比特率)、Session(会话)-AMBR等。而Filter(过滤器)(或称为SDF模板)包含描述数据包的特征的参数,并用于过滤出特定的数据包已绑定到特定的QoS Flow上。这里,最常用的Filter(过滤器)就是IP(互联网协议,Internet Protocol)五元组,即源和目标IP地址、源和目标端口号、协议类型。
应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种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这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
应理解,在本申请的实施例中提到的“指示”可以是直接指示,也可以是间接指示,还可以是表示具有关联关系。举例说明,A指示B,可以表示A直接指示B,例如B可以通过A获取;也可以表示A间接指示B,例如A指示C,B可以通过C获取;还可以表示A和B之间具有关联关系。
在本申请实施例的描述中,术语“对应”可表示两者之间具有直接对应或间接对应的关系,也可以表示两者之间具有关联关系,也可以是指示与被指示、配置与被配置等关系。
为便于理解本申请实施例的技术方案,以下对本申请实施例的相关技术进行说明,以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。
图3是根据本申请一实施例的数据处理方法的示意性流程图。该方法可选地可以应用于图1所示的系统,但并不仅限于此。该方法包括以下内容的至少部分内容。
S310、终端设备的第一协议实体对数据包进行处理,得到处理后的数据包;其中,所述第一协议实体中包含网络编码(NC,Network Coding)协议。
在执行上述S310之前,所述方法还可以包括:
所述终端设备接收NC配置信息(NC config,Network Coding config);
其中,所述NC配置信息中包括以下至少之一:
所述NC使能的标识;
所述NC协议采用的编码方式的标识;
所述NC协议支持分段的最大长度L,L为大于等于2的整数;
所述NC协议支持的最大分段个数;
所述NC协议支持的数据流数量;
所述NC协议支持的数据包处理数量N,N为大于等于2的整数;
所述NC协议支持的NC算法。
上述NC使能的标识可以包括第一标识或第二标识;所述第一标识可以表示NC使能或者开启NC协议,或者使用NC协议功能;第二标识可以表示不使用NC功能,或者不使用NC协议功能,或不使用NC协议等等。其中,所述第一标识可以为1,第二标识可以为0;或者所述第一标识为“enable”,第二表示为“disable”,这里不对其进行穷举。
所述NC协议采用的编码方式的标识(比如表示为coding profile id),还可以称为NC协议采用的编码协议的标识。具体的,所述编码方式的标识(或编码协议的标识)可以用于表示NC协议使用的NC算法所对应的标识。举例来说,NC算法-1对应的编码方式的标识(或编码协议的标识)为01,NC算法-2对应的编码方式的标识(或编码协议的标识)为02等等。
所述NC协议支持分段(segment)的最大长度L,L为大于等于2的整数,其中,所述NC协议支持分段的最大长度指的是:NC协议支持分段且每个分段的长度均为L。L的单位可以是bit或者byte等等。对分段的最大长度进行配置是由于需要NC协议处理的比特流的长度要求一致。
所述NC协议支持的最大分段个数,指的是:NC协议支持分段且分段的数量不可超过上述最大分段个数。
所述NC协议支持的数据流数量,也就是说,NC协议支持的数据流的数量可以是一个或多个。
所述NC协议支持的数据包处理数量N,这里N可以根据实际情况设置,比如可以为大于等于2的整数,假设N等于2,也就是说每次针对2个数据包进行NC处理,若支持的数据流的数量为1个,则可以针对该数据流中的每两个数据包进行NC;若支持的数据流数量为2个或更多,可以是将每两个数据流分别包含的数据包进行NC。
所述NC协议支持的NC算法具体可以为所述NC协议支持的NC算法的名称,比如,喷泉码,当然所述NC算法还可以有其他算法,只是本实施例不对其进行穷举。
应理解,上述NC配置信息可以包含以上内容中可以仅包含部分内容,也可以包含全部内容。示例性的,在NC配置信息中可以仅包括:NC协议采用的编码方式的标识、NC协议支持分段的最大长度L; 这种情况下,其他的NC配置可以采用默认配置,比如终端设备预先配置了NC协议支持的数据包处理数量N,以及终端设备预先配置NC使能,并且终端设备还预先配置了编码方式的标识与NC算法之间的对应关系,此时,所述终端设备可以基于上述NC配置信息配置的部分内容执行NC处理。需要指出这里仅为示例性说明,不代表NC配置信息中仅可以包含上述内容,实际处理中可以根据实际情况对NC配置信息的具体内容进行配置,只是本实施例不对其进行穷举。
所述NC配置信息由以下至少之一携带:无线资源控制(RRC,Radio Resource Control)配置、小区配置、分组数据汇聚协议(PDCP,Packet Data Convergence Protocol)配置、无线承载配置、无线链路控制(RLC,Radio Link Control)配置、介质访问控制(MAC,Medium Access Control)配置、逻辑信道配置。
需要指出的是,上述NC配置信息可以是在上述信息任意之一中携带,比如,在RRC配置中携带;并且若在其中任意之一携带的情况下,可以在其他信息中不携带,也就是说NC配置信息仅需要通过上述信息任意之一传输一次即可。
还需要指出,若NC配置信息需要更改,比如,网络设备需要终端设备采用新的NC编码方式进行NC处理,此时可以发送更新后的新的NC配置信息,该新的NC配置信息可以与上一次发送的NC配置信息分别采用不同的信息携带,比如,上一次发送的NC配置信息由MAC配置携带,新的NC配置信息可以由PDCP配置携带,可以由网络设备根据实际情况来确定,这里不对其进行限定。
所述NC配置信息为目标粒度下的至少部分对象的配置;其中,所述目标粒度为以下至少之一:承载、PDCP实体、RLC实体、NC实体、终端设备、小区、MAC实体。
其中,所述目标粒度下的至少部分对象中,所述对象可以与所述目标粒度相关,比如,所述目标粒度为承载,相应的,所述目标粒度下的至少部分对象可以指的是承载粒度下的一个或多个承载;再比如,所述目标粒度为终端设备,相应的,所述目标粒度下的至少部分对象指的是一个或多个终端设备。
上述目标粒度可以是一个或多个,比如,目标粒度为承载和小区,相应的,目标粒度下的至少部分对象可以指的是一个或多个小区下的一个或多个承载。
还需要指出,所述NC配置信息中还可以包含所述目标粒度以及所述目标粒度下的至少部分对象;比如,在所述NC配置信息中可以指示目标粒度为承载,目标粒度下的至少部分对象为承载的编号(或称为序号或索引号),比如在所述NC配置信息中包含:NC协议的目标粒度为承载,NC协议应用于承载-1、承载-2;或者,对应这个承载1和承载2的配置来配置NC协议;再比如,在所述NC配置信息中可以指示目标粒度为承载和终端设备,目标粒度下的至少部分对象为承载的编号(或称为序号或索引号)以及终端设备的标识(比如终端设备的IMSI),比如在所述NC配置信息中包含:NC协议的目标粒度为承载和终端设备,NC协议应用于终端设备A和终端设备B,以及承载-1和承载-2。
上述仅以目标粒度为承载、终端设备、小区中至少之一做了示例性说明,不作为所述NC配置信息的目标粒度及其对应的至少部分对象的限定,实际处理中可以设置其他目标粒度及其对应的至少部分对象,只是这里不做穷举。
进一步地,所述第一协议实体在与目标粒度下至少部分对象的所述NC配置信息对应的情况下,存在所述NC协议。
前述已经说明NC配置信息可以是针对目标粒度下的至少部分对象的配置,相应的,所述终端设备可以基于接收到的NC配置信息来确定是否在第一协议实体中增加所述NC协议,或者,所述终端设备可以基于所述NC配置信息,确定所述第一协议实体中是否包含NC协议。
具体的,所述终端设备可以包含一个或多个第一协议实体,其中不同的第一协议实体可以对应不同的目标粒度下的不同对象;所述终端设备在接收到所述NC配置信息之后,可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的第一协议实体中增加NC协议,而其他第一协议实体中不增加NC协议。
举例来说,终端设备可以有2个第一协议实体,其中,第一协议实体1对应了承载作为目标粒度下的承载1,第一协议实体2对应了以承载作为目标粒度下的承载2;若所述NC配置信息是针对承载作为目标粒度下的承载1的配置,则所述终端设备可以确定在承载1所对应的第一协议实体1中包含NC协议,而在第一协议实体2中则不包含所述NC协议。
再举例来说,终端设备可以有2个第一协议实体,其中,第一协议实体1对应了RLC实体作为目标粒度下的RLC实体1,第一协议实体2对应了以RLC实体作为目标粒度下的RLC实体2;若所述NC配置信息是针对RLC实体作为目标粒度下的RLC实体1的配置,则所述终端设备可以确定在RLC实体1所对应的第一协议实体1中包含NC协议,而在第一协议实体2中则不包含所述NC协议。
上述仅为示例性说明,实际NC配置信息可以对应的目标粒度不限于上述几种,只是这里不做穷举。
另外,所述NC配置信息还可以为针对全部小区下的全部终端设备的配置,也就是可以不划分目标 粒度,此时,接收到该NC配置的终端设备可以在全部第一协议实体中均增加NC协议。
上述NC协议用于执行NC发送功能和/或NC接收功能;和/或,所述NC协议用于执行网络编码功能和/或网络解码功能。
具体来说,所述NC协议用于执行NC发送功能,与所述NC协议在所述第一协议实体中的位置相关。若所述NC协议为所述第一协议实体中间层的协议,则所述NC协议用于执行NC发送功能具体可以指的是:所述NC协议向所述第一协议实体中位于NC协议的下一层协议发送数据的功能。若所述NC协议为所述第一协议实体中的最后一层协议,则所述NC协议用于执行NC发送功能具体可以指的是:所述NC协议在所述第一协议实体中,向位于第一协议实体之后的下一个协议实体发送数据的功能。
所述NC协议用于执行NC接收功能,与所述NC协议在所述第一协议实体中的位置相关。若所述NC协议为所述第一协议实体中间层的协议,则所述NC协议用于执行NC接收功能具体可以指的是:所述NC协议从所述第一协议实体中位于NC协议的上一层协议接收数据的功能。若所述NC协议为所述第一协议实体中的第一层协议,则所述NC协议用于执行NC接收功能具体可以指的是:所述NC协议在所述第一协议实体中,从位于第一协议实体之前的上一个协议实体接收数据的功能。
所述NC协议用于执行网络编码功能,可以为:所述NC协议位于发送端的情况下,所述NC协议用于执行网络编码功能。
所述NC协议用于执行网络解码功能,可以为:所述NC协议位于接收端的情况下,所述NC协议用于执行网络解码功能。
上述发送端或接收端是针对数据流向或走向而言的,所述终端设备可以即为发送端也为接收端,比如所述终端设备在向网络设备发送上行数据的时候,该终端设备可以为发送端;所述终端设备接收网络设备的下行数据的时候,该终端设备可以为接收端。
需要指出若终端设备为发送端的情况下,所述NC协议可以执行NC接收功能、网络编码功能以及NC发送功能;所述终端设备为接收端的情况下,所述NC协议可以执行NC接收功能、网络解码功能以及NC发送功能。
再进一步地,所述NC协议对应第一NC实体;所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理。

或者,所述NC协议对应第二NC实体和第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。
具体的,所述第二NC实体可以指的是具备上述NC发送功能、NC接收功能、网络解码功能中全部功能的实体;所述第三NC实体可以具备上述NC发送功能、NC接收功能、网络编码功能全部功能的实体。
也就是说,NC协议可以对应一个收发共用的第一NC实体,或者NC协议可以对应一个第二NC实体以及一个第三NC实体,该第二NC实体用于对接收到的数据包进行处理,该第三NC实体用于对待传输数据包进行处理。
上述第一NC实体可以称为第一NC instance;所述第二NC实体可以称为第二NC instance;所述第三NC实体可以称为第三NC instance。
上述S310中,所述终端设备的第一协议实体对数据进行处理,得到处理后的数据,可以将所述终端设备作为接收端或发送端分别来进行说明,具体如下:

应理解,若所述第一协议实体中NC协议位于中间层,则所述第二待传输数据包具体可以指的是:所述第一输入信息至少包含所述待传输数据包在所述NC协议之前的其他协议处理后的第一待传输数据包。或者,若所述第一协议实体中NC协议位于第一层,则所述第二待传输数据包可以指的是:所述 第一输入信息包含上一个协议实体发来的所述第一待传输数据包。

上述第一协议实体中的所述NC协议执行分段处理为预定义的,或网络设备配置的;和/或,所述第一协议实体中的所述NC协议执行填充处理为预定义的,或网络设备配置的。
也就是说,所述NC协议中是否执行所述分段处理,可以是预定义的,比如所述终端设备可以默认针对每个待传输数据包均执行分段处理或均不执行分段处理。或者,所述NC协议中是否执行所述分段处理也可以为网络设备配置的,比如所述网络设备在发来的所述NC配置信息中包含了NC协议支持的分段的最大长度L的情况下,所述终端设备基于所述NC配置信息执行分段处理。
所述NC协议中是否执行所述填充处理,可以是预定义的,比如所述终端设备可以默认针对每个待传输数据包均执行填充处理或均不执行填充处理。或者,所述NC协议中是否执行所述填充处理也可以为网络设备配置的,比如所述网络设备在发来的所述NC配置信息中包含了填充指示的情况下,所述终端设备基于所述NC配置信息执行填充处理。
本情况中所述终端设备为发送端,相应的,所述NC协议执行的NC算法处理具体可以为网络编码处理。
所述NC协议还用于接收所述第一协议实体中位于所述NC协议之前的协议发来的处理后的第一待传输数据包,将所述处理后的第一待传输数据包作为所述第二待传输数据包;以及将所述第一输出结果递交至所述第一协议实体中的下一层协议。也就是说,所述NC协议位于所述第一协议实体的中间的情况下,所述NC协议接收到的是其在所述第一协议实体中的前一层或前多层协议处理后的第一待传输数据包,将所述处理后的第一待传输数据包作为所述第二待传输数据包;通过所述NC协议执行前述处理至少之一之后,得到所述第一输出结果;将该第一输出结果递交至所述第一协议实体的下一层协议。
或者,所述NC协议还用于接收位于所述第一协议实体之前的实体发来的第一待传输数据包,将所述第一待传输数据包作为所述第二待传输数据包;以及将所述第一输出结果递交至所述第一协议实体中的下一层协议。也就是说,所述NC协议位于所述第一协议实体的第一层的情况下,所述NC协议接收到的是所述第一协议实体之前的实体发来的第一待传输数据包,将所述第一待传输数据包作为所述第二待传输数据包;通过所述NC协议执行前述处理至少之一之后,得到所述第一输出结果;将该第一输出结果递交至所述第一协议实体的下一层协议。

进一步地,在基于上述NC协议对第一输入信息执行处理得到第一输出结果之后,所述第一协议实体还可以在最终得到的第一数据包中携带第一指示信息。
具体的,所述第一数据包中携带第一指示信息;所述第一指示信息中包括以下至少之一:

其中,所述是否执行NC的指示可以包含第一指示值或第二指示值,所述第一指示值可以用于表示所述第一数据包未执行NC处理,第二指示值可以用于表示所述第一数据包执行NC处理。进一步地,若所述第一数据包是否执行NC的指示表示所述第一数据包未执行NC,则所述第一指示信息中可以不包含其他信息。若所述第一数据包是否执行NC的指示表示所述第一数据包执行NC,则所述第一指示信息中可以包含其他信息。
所述NC协议采用的编码方式的标识可以是所述终端设备本次进行NC处理所采用的编码方式的标识,比如所述终端设备可以支持3种编码方式,本次使用了编码方式2,则所述NC协议采用的编码方式的标识具体为编码方式2。
所述NC协议支持的NC算法可以是所述终端设备本次进行NC处理所采用的NC算法,比如所述终端设备可以支持3种NC算法,本次使用了NC算法1,则所述NC协议采用的NC算法具体可以为NC算法1的具体名称。
所述NC协议支持分段的最大长度L,可以指的是所述NC配置信息中携带的NC协议支持分段的最大长度L。

所述NC协议支持的数据包处理数量N可以是所述NC配置信息中携带的NC协议支持的数据包处理数量N。
所述是否执行分段的指示用于表示本次NC处理是否执行分段,比如,可以采用指示值的方式来表示,若指示为1则可以表示本次NC处理执行分段,否则表示本次NC处理未执行分段。
所述分段的实际长度,可以指的是所述终端设备本次进行NC处理进行分段的长度,该分段的长度可以是小于或等于所述NC配置信息中携带的NC协议支持分段的最大长度L。
所述分段的实际个数,可以指的是所述终端设备本次进行NC处理分段的个数,可以小于或等于所述NC配置信息中携带的NC协议支持的最大分段个数,比如NC配置信息中携带的NC协议支持的最大分段个数为20,则所述分段的实际个数可以为10个。
所述是否为NC的首个分段的指示,也就是说,在前述是否执行分段的指示中若表征本次执行分段的情况下,可以在所述第一数据包中携带其是否为NC的第一个分段的指示;比如,具体可以为一个标志值,若为1可以表示该第一数据包为NC的首个分段数据包。
所述是否为NC的最后一个分段的指示,也就是说,在前述是否执行分段的指示中若表征本次执行分段的情况下,可以在所述第一数据包中携带其是否为NC的最后一个分段数据包的指示;比如,具体可以为一个标志值,若为1可以表示该第一数据包为NC的最后一个分段。
所述是否携带填充的指示可以为一个指示值,比如若为1可以表示第一数据包携带填充,否则表示第一数据包不携带填充;或者,还可以为其他指示方式,比如可以直接写入“padding”这样的指示信息来表示第一数据包携带填充,当然还可能有其他指示方式,只是这里不进行穷举。
所述填充的长度,可以是在前述第一数据包是否携带填充的指示表征所述第一数据包携带填充的情况下存在的内容,所述第一数据包填充的长度具体可以为bit值,比如包含了8bit的填充,或32bit的填充等等。
所述是否执行重组的指示可以用于指示接收端在接收到该第一数据包的情况下是否对所述第一数据包及其他分段数据包进行重组;具体可以为一个指示值,比如若为1的情况下,用于指示接收端在接收到该第一数据包的情况下对所述第一数据包及其他分段数据包进行重组,否则不进行重组;又或者,可以为一个具体的指示信息比如“reassembly”来指示接收端在接收到该第一数据包的情况下对所述第一数据包及其他分段数据包进行重组。
所述是否执行去填充的指示以用于指示接收端在接收到该第一数据包的情况下是否对所述第一数据包进行去填充处理;具体可以为一个指示值,比如若为1的情况下,用于指示接收端在接收到该第一数据包的情况下对所述第一数据包进行去填充处理,否则不进行去填充处理;又或者,可以为一个具体的指示信息比如“去填充”来指示接收端在接收到该第一数据包进行去填充处理。
应理解,在实际发送的第一指示信息中可以包含上述全部内容,又或者可以仅包含其中一个或多个内容。另外,上述接收端可以指的是网络设备;所述第一待传输数据包或第二待传输数据包可以指的是所述终端设备待传输的上行数据包。
举例来说,上述第一数据包是否为NC的首个分段的指示、所述第一数据包是否为NC的最后一个分段的指示、分段的实际个数可以仅包含其中两个,比如,在所述第一数据包中可以携带上述第一数据包是否为NC的首个分段的指示、所述第一数据包是否为NC的最后一个分段的指示,相应的,在接收端可以根据该第一数据包是否为NC的首个分段的指示、所述第一数据包是否为NC的最后一个分段的指示,来确定是否接收到全部NC处理的数据包。
又比如,在所述第一数据包中可以携带上述第一数据包是否为NC的首个分段的指示、分段的实际个数,相应的,在接收端可以根据该第一数据包是否为NC的首个分段的指示、分段的实际个数,来确定是否接收到全部NC处理的数据包。
再比如,在前述是否执行分段的指示中若表征本次执行分段的情况下,可以在所述第一数据包中携带其是否为NC的最后一个分段数据包的指示;若是否执行分段的指示中若表征本次没有执行分段的情况下,可以在所述第一数据包中可以不携带其是否为NC的最后一个分段数据包的指示。
上述仅为示例性说明,实际处理中所述第一指示信息所包含的内容可以有其他的组合形式,这里不进行穷举。
所述第一指示信息在所述第一数据包的以下部分之一携带:所述第一数据包的包头、所述第一数据包的有效载荷部分、所述第一数据包的新包头。
其中,所述第一数据包的包头与所述第一数据包的新包头不同之处在于,所述第一数据包的新包头可以为新构建的一个包头的格式(format),而所述第一数据包的包头则可以指的是第一数据包原格式下的包头中的某一个字段中携带所述第一指示信息。
所述第一数据包具体为哪种类型的数据包与所述第一协议实体相关,比如第一协议实体为PDCP实体,则所述第一数据包可以为PDCP PDU,该PDCP PDU通过以下之一携带上述第一指示信息:所述PDCP PDU的包头、所述PDCP PDU的有效载荷(payload)部分、所述PDCP PDU的新包头。比如第一协议实体为RLC实体,则所述第一数据包可以为RLC PDU,该RLC PDU通过以下之一携带上述第一指示信息:所述RLC PDU的包头、所述RLC PDU的有效载荷(payload)部分、所述RLC PDU的新包头。比如,第一协议实体为SDAP实体,则所述第一数据包可以为SDAP PDU,该SDAP PDU通过以下之一携带上述第一指示信息:所述SDAP PDU的包头、所述SDAP PDU的有效载荷(payload)部分、所述SDAP PDU的新包头。再比如,第一协议实体为MAC实体,则所述第一数据包可以为MAC PDU,该MAC PDU通过以下之一携带上述第一指示信息:所述MAC PDU的包头、所述MAC PDU的有效载荷(payload)部分、所述MAC PDU的新包头。以上仅为示例性说明,本实施例不做穷举。
应理解,上述第一协议实体具体可以为PDCP实体、RLC实体、SDAP实体、MAC实体中任意之一。还应理解的是,在本情况一中所述NC协议中执行的NC算法处理具体指的是网络编码处理。
针对上述情况一,下面分别结合所述第一协议实体为不同类型的实体的处理方式进行说明:
方式1、所述第一协议实体为第一PDCP实体。
具体的,所述终端设备可以包含一个或多个PDCP实体,其中不同的PDCP实体可以对应不同的目标粒度下的不同对象;所述终端设备在接收到所述NC配置信息之后,可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的PDCP实体中增加NC协议,而其他PDCP实体中不增加NC协议。
举例来说,终端设备可以有2个PDCP实体,其中,PDCP实体1对应了承载作为目标粒度下的承 载1,PDCP实体2对应了以承载作为目标粒度下的承载2;若所述NC配置信息是针对承载作为目标粒度下的承载1的配置,则所述终端设备可以确定在承载1所对应的PDCP实体1中包含NC协议,而在PDCP实体2中则不包含所述NC协议。
也就是根据NC配置信息确定执行NC的一个或多个PDCP实体中的任意之一称为第一PDCP实体进行后续说明,应理解,若存在执行NC的多个PDCP实体都可以执行NC,则所述执行NC的多个PDCP实体中不同PDCP实体的处理可以为相同的,只是这里不做重复说明。
上述第一PDCP实体还可以替换称为第一PDCP层(layer)或者第一PDCP entity。上述NC协议还可以替换性的称为NC功能、NC功能模块等等,本实施例不对其进行穷举。
基于前述说明,所述第一PDCP实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第一PDCP实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第三NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
其中,所述NC协议子层的功能应用于目标数据承载DRB的所述第二待传输数据包和/或目标信令承载SRB的所述第二待传输数据包。
前述已经说明所述第一协议实体在与目标粒度下至少部分对象的所述NC配置信息对应的情况下,存在所述NC协议子层;也就是说,在第一PDCP实体中的NC协议可以是基于NC配置信息的目标粒度下的至少部分对象所配置的。所述目标粒度若为承载,该目标粒度下的至少部分对象为目标DRB和/或目标SRB;该目标DRB可以为一个或多个,目标SRB也可以为一个或多个。比如,一个DRB1(即目标DRB)对应所述第一PDCP实体,所述第一PDCP实体中的NC协议会对该DRB1的第二待传输数据包进行NC处理。比如,一个SRB1(即目标SRB)对应所述第一PDCP实体,所述第一PDCP实体中的NC协议会对该SRB1的第二待传输数据包进行NC处理。处理后的数据再发送至下一个实体或该实体的NC子层的下一子层。
在所述第一协议实体为所述第一PDCP实体的情况下,所述第一数据包为PDCP协议数据单元(PDU,Protocol Data Unit);所述第二待传输数据包可以为:PDCP SDU或PDCP PDU的数据部分。相应的,所述NC协议的功能应用于所述PDCP PDU的数据部分,或者,所述NC协议子层的功能应用于所述PDCP PDU的PDCP SDU。也就是说,在所述第一PDCP实体中NC协议用于对所述PDCP PDU的数据部分进行处理,或者,在所述第一PDCP实体中的NC协议用于对PDCP PDU的PDCP SDU进行处理。
其中,所述PDCP SDU为所述第二待传输数据包,而经过所述第一PDCP实体的NC协议对该PDCP SDU即第二待传输数据包进行处理之后,在所述第一PDCP实体发出的所述第一数据包即为PDCP PDU。所述PDCP PDU可以是在所述PDCP SDU的基础上封装得到的。
所述PDCP PDU还可以分为PDCP数据PDU或PDCP控制PDU。一种优选示例中,本实施例提供的方案尤其适用于所述PDCP PDU为PDCP数据PDU。当然,本实施例提供的方案并不排除可以应用于PDCP控制PDU中,只是这里不进行穷举。
或者,所述NC协议的功能应用于以下数据单元之外的其他数据单元:服务数据适配协议SDAP控制PDU和/或SDAP包头。也就是说,本实施例提供的方案中,对上述数据单元不执行NC处理。若第二待传输数据包包含除上述数据单元之外的数据单元的情况下,则可以执行NC处理,比如,第二待传输数据包为SDAP的数据PDU的情况下,可以对其执行NC处理。当然,还可以包含其他情况,这里不进行穷举。
所述第一数据包中还携带所述第一数据包的序列号(SN,Sequence Number)。该SN号可以适用于对端能够得知所述第一数据包为执行NC操作的第几个分段数据包,或者,适用于对端能够得知所述第一数据包是哪个原数据包的分段和/或是不是原数据包的分段,进而可以便于接收端(即对端,即网络设备)能够进行级联或重组处理。
比如,在所述第一数据包也就是PDCP PDU中携带的第一指示信息可以指示所述第一数据包是否为NC的首个分段数据包的指示,若该指示为否,则所述第一数据包为NC的多个分段数据包中之一;相应的,对端可以基于该第一数据包的序列号以及缓存/当前缓存的全部分段数据包进行重组处理。
比如,在所述第一数据包也就是PDCP PDU中携带的第一指示信息可以指示所述第一数据包是否为NC分段的数据包的指示,若该指示为是,则所述第一数据包为SN为特定值的NC的多个分段数据包中之一;相应的,对端可以基于该第一数据包的序列号以及缓存/当前缓存的全部分段数据包进行重组处理。
本处理方式中,所述NC协议在所述第一PDCP实体中的位置也可以是根据实际情况进行设置的,分别来说:
所述NC协议位于所述第一PDCP实体中的第一协议之后;其中,所述第一协议为以下之一:头压缩协议、完整性保护协议、加密协议。
和/或,所述NC协议位于所述第一PDCP实体中的第二协议之前;其中,所述第二协议为以下之一:头压缩协议、完整性保护协议、加密协议、加PDCP头协议。
可选的,NC协议位于所述第一PDCP实体中的加PDCP头协议之后。此时,需要重新执行生成PDCP包头、分段等处理至少之一。
结合图4-图7进行示例性说明,在图4-图7中,发送PDCP实体为前述第一PDCP实体;网络编码(NC)即前述NC协议,头压缩即前述头压缩协议(或可以称为头压缩实体、头压缩协议子层、头压缩层等等这里不做穷举),完整性保护即前述完整性保护协议(或可以称为完整性保护实体、完整性保护协议子层、完整性保护层等等这里不做穷举),加密即前述加密协议(或可以称为加密实体、加密协议子层、加密层等等这里不做穷举),加PDCP头即前述加PDCP头协议(或可以称为加PDCP头实体、加PDCP头协议子层、加PDCP头层等等这里不做穷举)。
参见图4,NC即NC协议,该NC协议位于第二协议之前,所述第二协议为图4中的头压缩。参见图5和图6,第二协议为图5中的完整性保护,所述NC协议位于所述完整性保护协议之前,或者第一协议为图5或图6中的头压缩,所述NC协议位于头压缩协议之后。参见图7,第二协议为图7中的加密,所述NC协议位于所述加密协议之前,或者第一协议为图7中的完整性保护,则所述NC协议位于完整性保护协议之后。
所述第一PDCP实体中对所述NC协议得到的所述第一输出结果不执行的处理包括以下至少之一:头压缩、完整性保护、加密。其中,所述第一PDCP实体中对所述NC协议处理得到的所述第一输出结果不执行的处理,与所述NC协议在所述第一PDCP实体中的位置相关。
也就是说,所述NC协议在所述第一PDCP实体中所处的位置,会对所述NC协议的第一输出结果所执行的处理相关,比如,所述NC协议位于完整性保护协议之前、且位于头压缩协议之后,则NC协议收到的第二待传输数据包为头压缩处理后的第一待传输数据包,因此针对所述第一输出结果不再执行头压缩处理。比如,所述NC协议位于完整性保护协议之后、且位于加密协议之前,则NC协议收到的第二待传输数据包为头压缩以及完整性保护处理后的第一待传输数据包,因此针对所述第一输出结果不再执行头压缩处理以及完整性保护处理。再比如,所述NC协议位于加密协议之后、且添加PDCP包头协议之前,则NC协议收到的第二待传输数据包为头压缩、完整性保护、加密处理后的第一待传输数据包,因此针对所述第一输出结果不再执行头压缩、完整性保护、加密处理。
方式2、所述第一协议实体为第一RLC实体。
具体的,所述终端设备可以包含一个或多个RLC实体,其中不同的RLC实体可以对应不同的目标粒度下的不同对象;所述终端设备在接收到所述NC配置信息之后,可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的RLC实体中增加NC协议,而其他RLC实体中不增加NC协议。
举例来说,终端设备可以有4个RLC实体,其中,RLC实体1和RLC实体2对应了以PDCP实体作为目标粒度下的PDCP1,RLC实体3和RLC实体4对应了以PDCP实体作为目标粒度下的PDCP2;若所述NC配置信息是针对PDCP实体作为目标粒度下的PDCP1的配置,则所述终端设备可以确定在PDCP1所对应的RLC实体1和RLC实体2中包含NC协议,而在PDCP2中所对应的RLC实体3和RLC实体4中不包含所述NC协议。
也就是根据NC配置信息确定执行NC的一个或多个RLC实体中的任意之一称为第一RLC实体进行后续说明,应理解,若存在多个RLC实体都可以执行NC,则所述执行NC的多个RLC实体中不同RLC实体的处理可以为相同的,只是这里不做重复说明。
上述第一RLC实体还可以替换称为第一RLC层(layer)或者第一RLC entity。
基于前述说明,所述第一RLC实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第一RLC实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第三NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
所述RLC可以存在UM(非确认,Un-Acknowledged mode)、AM(确认,Acknowledged mode)以 及TM(transport mode,透传模式)三种传输模式,比如,所述NC协议的功能应用于RLC非确认模式UM传输的所述第二待传输数据包和/或RLC确认模式AM传输的所述第二待传输数据包。其中,所述NC协议针对RLC的哪种模式传输的第二待传输数据包进行处理,可以是预定义的,或网络设备配置的(比如通过NC配置信息中携带,或其他信息中携带)。
所述第一RLC实体为双向(bi-directional)RLC实体或单向(unidirectional)RLC实体。也就是说,所述NC协议针对哪种类型的RLC实体中传输的待传输数据包进行处理,可以是预定义的,或网络设备配置的(比如通过NC配置信息中携带,或其他信息中携带)。应理解上述仅为示例性说明,实际可以针对全部RLC实体类型均进行处理,只是不做穷举。
在所述第一协议实体为所述第一RLC实体的情况下,所述第一数据包为RLC协议数据单元PDU。
所述NC协议的功能应用于所述RLC PDU的数据部分,或RLC SDU,或RLC SDU的数据部分。也就是说,所述第二待传输数据包具体为RLC PDU的数据部分,或者,RLC SDU,或者,RLC SDU的数据部分。
其中,所述RLC PDU的RLC SDU可以理解为所述RLC SDU为所述待传输数据包,而经过所述第一RLC实体的NC协议对该RLC SDU处理之后,在所述第一PDCP实体发出的所述第一数据包即为RLC PDU。所述RLC PDU可以是在所述RLC SDU的基础上封装得到的。
其中,所述第一数据包中还携带所述第一数据包的序列号(SN,Sequence Number)。也就是说,在所述RLC PDU中还可以携带SN号。该SN号可以适用于对端能够得知所述第一数据包为执行NC操作的第几个数据包,进而可以便于接收端(即对端)能够进行级联或重组处理。比如,在所述第一数据包也就是RLC PDU中携带的第一指示信息可以指示所述第一数据包是否为NC的首个分段的指示,若该指示为否,则所述第一数据包为NC的多个分段中之一;相应的,对端可以基于该第一数据包的序列号以及当前缓存的从NC首个分段数据包进行重组处理。
本处理方式中,所述NC协议在所述第一RLC实体中的位置也可以是根据实际情况进行设置的,比如:
所述NC协议位于所述第一RLC实体中的第三协议之前;所述第三协议包括以下之一:生成RLC包头并存储在待传输缓存协议,分段和修改RLC包头协议,添加RLC包头协议。
和/或,所述NC协议位于所述第一RLC实体中的第四协议之后;所述第四协议包括以下之一:生成RLC包头并存储在待传输缓存协议,分段和修改RLC包头协议。
可选的,NC协议位于所述第一RLC实体中的添加RLC头协议之后。此时,需要重新执行生成RLC包头、分段等处理至少之一。
具体的可以为:
所述NC协议位于所述第一RLC实体中的生成RLC包头并存储在待传输缓存协议之前;
或者,
所述NC协议位于所述第一RLC实体中的生成RLC包头并存储在待传输缓存协议之后,以及分段和修改RLC包头协议之前;
或者,
所述NC协议位于分段和修改RLC包头协议之后,以及添加RLC包头协议之前。
结合图8-图9进行示例性说明,图8-图9中发送UM-RLC实体(entity)即前述第一RLC实体;NC即NC协议,生成RLC包头并存储在待传输缓存即前述生成RLC包头并存储在待传输缓存协议,分段和修改RLC包头即前述分段和修改RLC包头协议,添加RLC包头即前述添加RLC包头协议。参见图8,NC协议位于生成RLC包头并存储在待传输缓存之前。参见图9,所述NC协议位于生成RLC包头并存储在待传输缓存之后,以及分段和修改RLC包头之前。
结合图10进行示例性说明,图10中对应了RLC为AM传输模式,其中左侧为第一RLC实体,NC即NC协议,生成RLC包头并存储在待传输缓存即前述生成RLC包头并存储在待传输缓存协议,分段和修改RLC包头即前述分段和修改RLC包头协议,添加RLC包头即前述添加RLC包头协议。参见图10,NC协议位于生成RLC包头并存储在待传输缓存之前。
应理解,上述仅为示例性说明,不作为限定。
所述第一RLC实体中对所述NC协议得到的所述第一输出结果不执行的处理包括以下至少之一:生成RLC包头并存储在待传输缓存、分段和修改RLC包头、添加RLC包头。其中,所述第一RLC实体中对所述NC协议处理得到的所述第一输出结果不执行的处理,与所述NC协议在所述第一RLC实体中的位置相关。
也就是说,所述NC协议在所述第一RLC实体中所处的位置,会对所述NC协议的第一输出结果所执行的处理相关,比如,所述NC协议位于分段和修改RLC包头之前、且位于生成RLC包头并存储 在待传输缓存协议之后,则NC协议收到的第二待传输数据包为生成RLC包头并存储在待传输缓存处理后的第一待传输数据包,因此针对所述第一输出结果不再执行生成RLC包头并存储在待传输缓存处理。
或者,需要重新执行生成RLC包头和/或并存储在待传输缓存处理。比如,所述NC协议位于分段和修改RLC包头之后、且位于添加RLC包头之前,则NC协议收到的第二待传输数据包为生成RLC包头并存储在待传输缓存、分段和修改RLC包头处理后的第一待传输数据包,因此针对所述第一输出结果不再执行生成RLC包头并存储在待传输缓存、分段和修改RLC包头处理。
或者,针对所述第一输出结果还需执行生成RLC包头并存储在待传输缓存、分段和修改RLC包头处理至少之一的操作(例如若由于NC需要执行分段和修改RLC包头的操作)。比如,所述NC协议位于添加RLC包头之后,则NC协议收到的第二待传输数据包为生成RLC包头并存储在待传输缓存、分段和修改RLC包头、添加RLC包头处理后的第一待传输数据包,因此针对所述第一输出结果不再执行生成RLC包头并存储在待传输缓存、分段和修改RLC包头、添加RLC包头处理,并且该第一输出结果直接输入到下一级实体中。
或者,针对所述第一输出结果还需执行生成修改存储在待传输缓存、分段和修改RLC包头、添加RLC包头处理至少之一的操作(例如若由于NC需要执行分段和修改RLC包头的操作)。
方式3、所述第一协议实体为第一SDAP实体。
具体的,所述终端设备可以包含一个或多个SDAP实体,其中不同的SDAP实体可以对应不同的目标粒度下的不同对象;所述终端设备在接收到所述NC配置信息之后,可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的RLC实体中增加NC协议,而其他RLC实体中不增加NC协议。
举例来说,终端设备可以有4个SDAP实体,其中,SDAP实体1对应了以承载作为目标粒度下的承载1,和SDAP实体2对应了以承载作为目标粒度下的承载2;若所述NC配置信息是针对承载作为目标粒度下的承载1的配置,则所述终端设备可以确定在承载1所对应的SDAP实体1中包含NC协议,而其他SDAP实体中不包含所述NC协议。
也就是根据NC配置信息确定执行NC的一个或多个SDAP实体中的任意之一称为第一SDAP实体进行后续说明,应理解,若存在执行NC的多个SDAP实体都可以执行NC,则所述执行NC的多个SDAP实体中不同SDAP实体的处理可以为相同的,只是这里不做重复说明。
上述第一SDAP实体还可以替换称为第一SDAP层(layer)或者第一SDAP entity。
基于前述说明,所述第一SDAP实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第一SDAP实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第三NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
在所述第一协议实体为所述第一SDAP实体的情况下,所述第一数据包为SDAP协议数据单元PDU。
在一种实施方式中,所述NC协议的功能应用于所述SDAP SDU的数据部分,或SDAP SDU,或SDAP PDU的数据部分。也就是说,在所述第一SDAP实体中NC协议用于对所述SDAP PDU的数据部分进行处理,或者,在所述第一SDAP实体中的NC协议用于对SDAP PDU的SDAP SDU进行处理,或者,在所述第一SDAP实体中的NC协议用于对SDAP SDU的数据部分进行处理。
其中,所述SDAP SDU可以为所述待传输数据包,而经过所述第一SDAP实体的NC协议对该SDAP SDU(或者对SDAP SDU的数据部分)处理之后,在所述第一SDAP实体发出的所述第一数据包即为SDAP PDU。所述SDAP PDU可以是在所述SDAP SDU的基础上封装得到的。或者,所述SDAP PDU为所述待传输数据包,经过所述第一SDAP实体的NC协议对该SDAP PDU的数据部分处理之后,在所述第一SDAP实体发出的所述第一数据包即为处理后的SDAP PDU。
在另一实施方式中,所述NC协议的功能应用于有SDAP包头的SDAP PDU。也就是说,待传输数据包可以为原SDAP PDU,若该原SDAP PDU中包含SDAP包头,则所述终端设备的第一SDAP实体中包含的NC协议可以对其进行NC处理;若该原SDAP PDU中不包含SDAP包头,则所述终端设备的第一SDAP实体中包含的NC协议可以不对其进行NC处理。
应理解,上述两种实施方式可以结合使用,比如,所述NC协议的功能应用于有SDAP包头的SDAP PDU的数据部分。
本处理方式中,所述NC协议在所述第一SDAP实体中的位置也可以是根据实际情况进行设置的, 比如,所述NC协议位于所述第一SDAP实体中的映射服务质量数据流QoS flow到DRB的协议之后,或,添加SDAP包头协议之前。比如,参见图11,NC协议即图11中的NC,发送SDAP实体即本实施例中的第一SDAP实体,该NC协议在图11示意出的位置为添加SDAP包头(即添加SDAP包头协议)之前,或映射服务质量数据流QoS flow到DRB(即映射服务质量数据流QoS flow到DRB)之后。
所述NC协议在所述第一SDAP实体中所处的位置,会对所述NC协议的第一输出结果所执行的处理相关,比如,所述NC协议位于映射服务质量数据流QoS flow到DRB的协议之后,则NC协议收到的第二待传输数据包为映射服务质量数据流QoS flow到DRB处理后的第一待传输数据包,因此所述第一SDAP实体中针对所述第一输出结果不再执行映射服务质量数据流QoS flow到DRB的处理。比如,所述NC协议位于添加SDAP包头之后,则NC协议收到的第二待传输数据包为映射服务质量数据流QoS flow到DRB、添加SDAP包头处理后的第一待传输数据包,因此所述第一SDAP实体中针对所述第一输出结果不再执行映射服务质量数据流QoS flow到DRB、添加SDAP包头的处理;并且该第一输出结果可以直接输入到该第一SDAP实体的下一个实体。
或者,在另一种实现方式中,需要重新执行生成SDAP包头、分段等处理至少之一,相应的第一SDAP实体中针对所述第一输出结果还需执行分段、修改SDAP包头、添加SDAP包头至少之一的处理,并将结果输出到该第一SDAP实体的下一个实体。
方式4、所述第一协议实体为第一MAC实体。
具体的,所述终端设备可以包含一个或多个MAC实体,其中不同的MAC实体可以对应不同的目标粒度下的不同对象;所述终端设备在接收到所述NC配置信息之后,可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的MAC实体中增加NC协议,而其他MAC实体中不增加NC协议。
举例来说,终端设备可以有4个MAC实体,所述NC配置信息为针对MAC实体为目标粒度下的MAC实体1的配置,则所述终端设备可以MAC实体1中包含NC协议,而其他MAC实体中不包含所述NC协议。
也就是根据NC配置信息确定执行NC的一个或多个MAC实体中的任意之一称为第一MAC实体进行后续说明,应理解,若存在执行NC的多个MAC实体都可以执行NC,则所述执行NC的多个MAC实体中不同MAC实体的处理可以为相同的,只是这里不做重复说明。
上述第一MAC实体还可以替换称为第一MAC层(layer)或者第一MAC entity。
基于前述说明,所述第一MAC实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第一MAC实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第三NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
在所述第一协议实体为所述第一MAC实体的情况下,所述第一数据包为MAC PDU。
在一种实施方式中,所述NC协议的功能应用于所述MAC SDU的数据部分,或MAC SDU,或MAC PDU的数据部分。也就是说,在所述第一MAC实体中NC协议用于对所述SDAP PDU的数据部分进行处理,或者,在所述第一MAC实体中的NC协议用于对MAC SDU进行处理,或者,在所述第一MAC实体中的NC协议用于对MAC SDU的数据部分进行处理。
本处理方式中,所述NC协议在所述第一MAC实体中的位置也可以是根据实际情况进行设置的,比如,所述NC协议位于所述第一MAC实体中的以下子层之一的之前或之后:逻辑信道优先级协议、复用协议、HARQ进程协议。比如,参见图12,图12中左侧为上述第一MAC实体,NC协议即图12中的NC,该NC协议在图12示意出的位置为HARQ进程(即HARQ进程协议)之前,复用(即复用协议)之后。
可选的,NC协议位于所述第一MAC实体中的生成MAC PDU或加MAC头协议之后。此时,需要重新执行生成MAC包头、分段、重新生成MAC PDU等处理至少之一。
所述第一MAC实体中对所述NC协议处理得到的所述第一输出结果不执行的处理,与所述NC协议在所述第一MAC实体中的位置相关。比如,所述NC协议位于复用协议之后,则NC协议收到的第二待传输数据包为逻辑信道优先级、复用处理后的第一待传输数据包,因此所述第一MAC实体中针对所述第一输出结果不再执行复用的处理。
比如,所述NC协议位于逻辑信道优先级之前,则NC协议收到的第二待传输数据包为从上一个实体直接传输来的第一待传输数据包,因此所述第一MAC实体中针对所述第一输出结果需要执行逻辑信 道优先级、复用以及HARQ处理。
比如,所述NC协议位于HARQ之后,则NC协议收到的第二待传输数据包为逻辑信道优先级、复用以及HARQ处理后的第一待传输数据包,因此所述第一MAC实体中针对所述第一输出结果不再执行逻辑信道优先级、复用以及HARQ处理;并且该第一输出结果直接输入到第一MAC实体的下一个实体。
情况二、所述终端设备为接收端。
所述终端设备的第一协议实体对数据包进行处理,得到处理后的数据包,可以包括:所述终端设备的第一协议实体对接收到的第一接收数据包进行处理,得到第二数据包;其中,所述第一协议实体中的所述NC协议用于对第二输入信息执行以下处理至少之一得到第二输出结果:重组处理、去填充处理、NC算法处理、NC数据缓存、NC分段冗余检测、NC分段删除;其中,所述第二输入信息至少包含第二接收数据包,所述第二接收数据包为所述第一接收数据包或处理后的所述第一接收数据包。
所述第二输入信息中包含的信息可以包含所述第二接收数据包;在此基础上,所述第二输入信息还可以包含以下信息中至少之一:NC算法的名称、每个分段的最大长度L、数据包处理数量N等等。或者,所述第一输入信息还可以包含以下信息中至少之一:编码方式(或编码协议)的标识、每个分段的最大长度L、数据包处理数量N等等。
应理解,若所述第一协议实体中NC协议位于中间层,则所述第二接收数据包具体可以指的是:所述第二输入信息至少包含所述第二数据包在所述NC协议前一层或前多层协议处理后的第一接收数据包。
或者,若所述第一协议实体中NC协议位于第一层,则所述第二输入信息至少包含所述第二数据包的相关信息具体可以指的是:所述第一输入信息包含上一个协议实体发来的所述第一接收数据包。
其中,所述第二输入信息中包含的至少部分信息的确定方式为以下之一:所述NC协议确定的、网络设备配置的、预定义的。
具体的,所述网络设备可以配置所述终端设备需要的第二输入信息的信息。
或者,所述终端设备可以预先定义自身进行NC协议的处理时需要在所述第二输入信息中包含的信息。
又或者,所述终端设备直接根据所述NC协议自身的需求确定所述第二输入信息中需要包含的信息。
再或者,所述终端设备可以基于所述网络设备的配置,和/或协议预定义,和/或自身的预定义确定所述第二输入信息中包含的至少部分信息之后,根据所述NC协议自身的需求增加、调整或更改所述第二输入信息中包含的全部信息;举例来说,所述终端设备可以基于所述网络设备的配置确定所述第二输入信息需要包含分段的最大长度L;进一步地,所述终端设备根据自身的NC协议需求确定所述第二输入信息中还需要包括第二接收数据包,分段的数量、编码方式的标识。
所述第二输入信息与所述NC配置信息所对应的所述目标粒度下的至少部分对象相关。也就是说,所述第二输入信息可以对应于目标粒度下的至少部分对象。前述已经说明所述NC配置信息可以为目标粒度下的至少部分对象的配置;相应的,在所述第二输入信息中也可以是对应了目标粒度下的至少部分对象。
比如,目标粒度为承载,目标粒度下的至少部分对象包含了承载1和承载2,则所述第二输入信息中包含的第二接收数据包具体为承载1以及承载2的第一接收数据包或处理后的第一接收数据包。再比如,目标粒度为RLC实体,目标粒度下的至少部分对象包含RLC实体1,则所述第二输入信息中包含的第二接收数据包具体为对应RLC实体1的第一接收数据包或处理后的第一接收数据包。这里不再进行穷举。
所述方法还包括:所述终端设备的第一协议实体对第一接收数据包进行缓存。也就是说,所述终端设备的所述第一协议实体对从上一个实体中接收到的所述第一接收数据包进行缓存。
所述方法还包括以下至少之一:所述终端设备的第一协议实体的所述NC协议对所述第二接收数据包执行分段丢失检测;所述终端设备的第一协议实体的所述NC协议对所述第二接收数据包执行针对分段的冗余检测。
分别来说,所述终端设备的第一协议实体的所述NC协议对所述第二接收数据包执行针对分段的冗余检测具体可以是:在所述第一协议实体中NC协议之前的其他协议将所述第一接收数据包进行处理,将得到的所述第二接收数据包发送至NC协议之后,所述NC协议可以对所述第二接收数据包执行针对分段的冗余检测。
比如,基于所述第二接收数据包中携带的SN以及当前缓存的其他分段数据包的SN来判断在所述第二接收数据包之前是否存在分段的冗余。举例来说,若所述第二接收数据包中携带的SN为005,在所述第二接收数据包之前缓存的首个分段数据包的SN为003,以及非首个分段数据包的SN为004, 则可以确定当前不存在分段的冗余。若所述第二接收数据包中携带的SN为005,在所述第二接收数据包之前缓存的首个分段数据包的SN为003,以及当前缓存的还有另外一个非首个分段数据包的SN为005,则可以确定当前存在分段的冗余。
进一步地,在确定存在分段的冗余的情况下,可以将当前冗余的分段进行删除。
所述终端设备的第一协议实体的所述NC协议对所述第二接收数据包执行分段丢失检测,可以是:在所述第一协议实体中NC协议之前的其他协议将所述第一接收数据包进行处理,将得到的所述第二接收数据包发送至NC协议之后,所述NC协议可以根据该第二接收数据包执行分段丢失检测。比如,基于所述第二接收数据包中携带的SN以及当前缓存的其他分段数据包的SN来判断在第二数据包之前是否存在丢失的数据包。举例来说,若第二接收数据包中携带的SN为005,在第二数据包之前缓存的首个分段数据包的SN为003,以及非首个分段数据包的SN为004,则可以确定当前不存在分段丢失。若第二数据包中携带的SN为005,在第二数据包之前缓存的首个分段数据包的SN为001,以及当前缓存的还有另外一个非首个分段数据包的SN为002,则可以确定当前存在分段丢失。
进一步地,所述方法还包括以下至少之一:

其中,在所述第二接收数据包之前存在丢失的分段数据包情况下,所述终端设备的所述第一协议实体中的所述NC协议删除所述第二接收数据包和/或在接收到所述第二接收数据包之前缓存的分段数据包,具体可以包括:基于所述NC协议执行分段丢失检测的检测结果,确定接收并缓存的首个分段数据包之后至所述第二接收数据包之间,存在丢失的分段数据包情况下,所述终端设备的所述第一协议实体中的所述NC协议删除所述第二接收数据包和在接收到所述第二接收数据包之前缓存的分段数据包。其中,所述在接收到所述第二接收数据包之前缓存的分段数据包具体为从首个分段数据包之后至接收到所述第二接收数据包前缓存的全部分段数据包。

其中,所述对所述第二接收数据包及所述至少一个分段数据包进行重组处理,得到重组处理后的数据包的处理中还可以包括:判断所述第二接收数据包是否为最后一个分段数据包,若不是,则基于等待接收下一个分段数据包;若是,则对所述第二接收数据包及所述至少一个分段数据包进行重组处理,得到重组处理后的数据包。
在所述终端设备的所述第一协议实体中的所述NC协议对所述第二接收数据包及所述至少一个分段数据包进行重组处理,得到重组处理后的数据包之后,所述方法包括:
对重组处理后的数据包执行去填充处理,得到去填充处理后的数据包。
也就是说,可以先对接收到的全部分段数据包进行重组,得到重组处理后的数据包后,进行去填充处理,得到去填充处理后的数据包作为所述NC协议的第二输出信息。
在得到上述重组处理后的数据包之后,还可以包括:向高层递交该重组后的数据包。
所述方法还包括以下至少之一:

在所述终端设备的所述第一协议实体中的所述NC协议对所述第二接收数据包执行去填充处理,得到去填充处理后的第二接收数据包。
也就是说,在针对所述第二数据包进行去填充处理之前,可以先进行缓存;在确定开始对该第二数据包进行去填充处理的时候,所述NC协议对该第二数据包进行去填充处理得到去填充处理后的数据包。
在所述终端设备的所述第一协议实体中的所述NC协议对所述第二接收数据包执行去填充处理,得到去填充处理后的数据包之后,所述方法包括:对去填充处理后的所述第二接收数据包及缓存的至少一个分段数据包进行重组处理,得到重组处理后的数据包。比如,可以判断所述第二接收数据包是否为最后一个分段数据包,若是,则将所述去填充处理后的所述第二接收数据包以及缓存的至少一个分段数据包进行重组处理,得到重组处理后的数据包;若不是,则继续等待接收下一个第二接收数据包。其中,所述缓存的至少一个分段数据包可以为之前已经完成去填充处理后的数据包。
应理解,上述NC协议所执行的去填充处理以及重组处理的先后顺序本实施例不做限定,可以是先执行重组处理再执行去填充处理;或者,可以是先执行去填充处理再执行重组处理。
所述第一协议实体中的所述NC协议执行重组处理为基于第三指示信息确定的,或预定义的,或网络设备配置的;
和/或,

应理解,在实际发送的第三指示信息中可以包含上述全部内容,又或者可以仅包含其中一个或多个内容。
所述第三指示信息在所述第一接收数据包的以下部分之一携带:所述第一接收数据包的包头、所述第一接收数据包的有效载荷部分、所述第一接收数据包的新包头。
其中,所述第一接收数据包的包头与所述第一接收数据包的新包头不同之处在于,所述第一接收数据包的新包头可以为新构建的一个包头的格式(format),而所述第一接收数据包的包头则可以指的是第一接收数据包原格式下的包头中的某一个字段中携带所述第一指示信息。
应理解,上述第一协议实体具体可以为PDCP实体、RLC实体、SDAP实体、MAC实体中任意之一。还应理解的是,在本情况二中所述NC协议中执行的NC算法处理具体指的是网络解码处理。本情况二中第一接收数据包可以为基于网络设备发送的下行数据包处理得到的数据包。
针对上述情况二,下面分别结合所述第一协议实体为不同类型的实体的处理方式进行说明:
方式1、所述第一协议实体为第二PDCP实体。
具体的,所述终端设备可以包含一个或多个PDCP实体,其中不同的PDCP实体可以对应不同的目标粒度下的不同对象;所述终端设备在接收到所述NC配置信息之后,可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的PDCP实体中增加NC协议,而其他PDCP实体中不增加NC协议。本方式中的第二PDCP实体与前述情况一的第一PDCP实体可以相同也可以不同,这里不对其进行限定。
举例来说,终端设备可以有2个PDCP实体,其中,PDCP实体1对应了承载作为目标粒度下的承载1,PDCP实体2对应了以承载作为目标粒度下的承载2;若所述NC配置信息是针对承载作为目标粒度下的承载1的配置,则所述终端设备可以确定在承载1所对应的PDCP实体1中包含NC协议,而在PDCP实体2中则不包含所述NC协议。
也就是根据NC配置信息确定执行NC的一个或多个PDCP实体中的任意之一称为第一PDCP实体进行后续说明,应理解,若存在执行NC的多个PDCP实体都可以执行NC,则所述执行NC的多个PDCP实体中不同PDCP实体的处理可以为相同的,只是这里不做重复说明。
上述第二PDCP实体还可以替换称为第二PDCP层(layer)或者第二PDCP entity。
基于前述说明,所述第二PDCP实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第二PDCP实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第二NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
其中,所述NC协议的功能应用于数据承载DRB承载的所述第二接收数据包和/或信令承载SRB中承载的所述第二接收数据包。
前述已经说明所述第一协议实体在与目标粒度下至少部分对象的所述NC配置信息对应的情况下,存在所述NC协议子层;也就是说,在第二PDCP实体中的NC协议可以是基于NC配置信息的目标粒度下的至少部分对象所配置的。所述目标粒度若为承载,该目标粒度下的至少部分对象为目标DRB和 /或目标SRB;该目标DRB可以为一个或多个,目标SRB也可以为一个或多个。比如,一个DRB1(即目标DRB)对应所述第二PDCP实体,所述第二PDCP实体中的NC协议会对该DRB1的第二接收数据包进行NC处理。
在所述第一协议实体为所述第二PDCP实体的情况下,所述第一接收数据包为PDCP协议数据单元PDU;第二接收数据包可以为PDCP PDU的数据部分,或PDCP SDU。相应的,所述NC协议的功能应用于所述PDCP PDU的数据部分,或者,所述NC协议子层的功能应用于所述PDCP PDU的PDCP SDU。
也就是说,所述第一接收数据包具体为PDCP PDU;在所述第二PDCP实体中NC协议用于对所述PDCP PDU的数据部分进行处理,或者,在所述第二PDCP实体中的NC协议用于对PDCP PDU的PDCP SDU进行处理。
所述PDCP PDU还可以分为PDCP数据PDU或PDCP控制PDU。一种优选示例中,本实施例提供的方案尤其适用于所述PDCP PDU为PDCP数据PDU。当然,本实施例提供的方案并不排除可以应用于PDCP控制PDU中,只是这里不进行穷举。
或者,所述NC协议的功能应用于以下数据单元之外的其他数据单元:服务数据适配协议SDAP控制PDU和/或SDAP包头。也就是说,本实施例提供的方案中,对上述数据单元不执行NC处理。若第二接收数据包包含除上述数据单元之外的数据单元的情况下,则可以执行NC处理,比如,第二接收数据包为SDAP的数据PDU的情况下,可以对其执行NC处理。当然,还可以包含其他情况,这里不进行穷举。
所述第一接收数据包中还携带所述第一接收数据包的SN。也就是说,在所述第二PDCP实体接收到的所述PDCP PDU中还可以携带SN。
本处理方式中,所述NC协议在所述第二PDCP实体中的位置也可以是根据实际情况进行设置的,分别来说:
所述NC协议位于所述第二PDCP实体中的第五协议之前;其中,所述第五协议为以下之一:解头压缩协议、完整性验证协议、解密协议、重排序协议。
和/或,所述NC协议位于所述第二PDCP实体中的第六协议之后;其中,所述第六协议为以下之一:解头压缩协议、完整性验证协议、解密协议、去PDCP头协议、重排序协议。
结合图4-图7进行示例性说明,在图4-图7中,接收PDCP实体为本情况中的第二PDCP实体;网络编码(NC)即前述NC协议,解头压缩即前述解头压缩协议(或可以称为解头压缩实体、解头压缩协议子层、解头压缩层等等这里不做穷举),完整性保护即前述完整性验证协议(或可以称为完整性验证实体、完整性验证协议子层、完整性验证层等等这里不做穷举),解密即前述解密协议(或可以称为解密实体、解密协议子层、解密层等等这里不做穷举),去PDCP头即前述去PDCP头协议(或可以称为去PDCP头实体、去PDCP头协议子层、去PDCP头层等等这里不做穷举)。
参见图4,NC即NC协议,该NC协议位于解头压缩之后。参见图5和图6,所述NC协议位于解头压缩之前,所述完整性验证之后。参见图7,所述NC协议位于所述解密之后,完整性验证之前。
所述第二PDCP实体中对所述NC协议得到的所述第二输出结果不执行的处理包括以下至少之一:解头压缩、完整性验证、解密。其中,所述第二PDCP实体中对所述NC协议处理得到的所述第二输出结果不执行的处理,与所述NC协议在所述第二PDCP实体中的位置相关。
比如,所述NC协议位于完整性验证协议之前、且位于解密协议之后,则NC协议收到的第二接收数据包为解密处理后的第一接收数据包,因此针对所述第二输出结果不再执行解密处理。比如,所述NC协议位于完整性验证协议之后、且位于头压缩之前,则NC协议收到的第二接收数据包为解密、完整性验证处理后的第一接收数据包,因此针对所述第二输出结果不再执行解密以及完整性验证处理。
方式2、所述第一协议实体为第二RLC实体。
具体的,所述终端设备可以包含一个或多个RLC实体,其中不同的RLC实体可以对应不同的目标粒度下的不同对象;所述终端设备在接收到所述NC配置信息之后,可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的RLC实体中增加NC协议,而其他RLC实体中不增加NC协议。应理解,本方式中的第二RLC实体与前述情况一的第一RLC实体可以相同也可以不同,本实施例不做限定。
举例来说,终端设备可以有4个RLC实体,其中,RLC实体1和RLC实体2对应了以PDCP实体作为目标粒度下的PDCP1,RLC实体3和RLC实体4对应了以PDCP实体作为目标粒度下的PDCP2;若所述NC配置信息是针对PDCP实体作为目标粒度下的PDCP1的配置,则所述终端设备可以确定在PDCP1所对应的RLC实体1和RLC实体2中包含NC协议,而在PDCP2中所对应的RLC实体3和RLC实体4中不包含所述NC协议。
也就是根据NC配置信息确定执行NC的一个或多个RLC实体中的任意之一称为第二RLC实体进 行后续说明,应理解,若存在执行NC的多个PDCP实体都可以执行NC,则所述执行NC的多个RLC实体中不同RLC实体的处理可以为相同的,只是这里不做重复说明。
上述第二RLC实体还可以替换称为第二RLC层(layer)或者第二RLC entity。
基于前述说明,所述第二RLC实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第二RLC实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第二NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
所述RLC可以存在UM(非确认,Un-Acknowledged mode)、AM(确认,Acknowledged mode)以及TM(transport mode,透传模式)三种传输模式,比如,所述NC协议的功能应用于RLC非确认UM模式传输的所述第二接收数据包和/或RLC确认模式AM传输的所述第二接收数据包。其中,所述NC协议针对RLC的哪种模式传输的第二接收数据包进行处理,可以是预定义的,或网络设备配置的(比如通过NC配置信息中携带,或其他信息中携带)。
所述第二RLC实体为双向(bi-directional)RLC实体或单向(unidirectional)RLC实体。也就是说,所述NC协议针对哪种类型的RLC实体中传输的待传输数据包进行处理,可以是预定义的,或网络设备配置的(比如通过NC配置信息中携带,或其他信息中携带)。应理解上述仅为示例性说明,实际可以针对全部RLC实体类型均进行处理,只是不做穷举。
在所述第一协议实体为所述第二RLC实体的情况下,所述第一数据包为RLC协议数据单元PDU。
所述NC协议的功能应用于所述RLC PDU的数据部分,或RLC SDU,或RLC SDU的数据部分。也就是说,所述第二接收数据包具体为RLC PDU的数据部分,或者,RLC SDU,或者,RLC SDU的数据部分。
其中,所述RLC PDU可以是在所述RLC SDU的基础上封装得到的。
其中,所述第一接收数据包中还携带所述第一接收数据包的序列号(SN,Sequence Number)。也就是说,在所述RLC PDU中还可以携带SN号。
本处理方式中,所述NC协议在所述第二RLC实体中的位置也可以是根据实际情况进行设置的,下面分以下几种位置来进行说明:
所述NC协议位于所述第二RLC实体中的第七协议之前或之后;
所述第七协议包括以下之一:去RLC包头协议,SDU重组协议。
结合图8-图9进行示例性说明,图8-图9中接收UM-RLC实体(entity)即前述第二RLC实体;NC即NC协议,去RLC包头即前述去RLC包头协议,SDU重组即前述SDU重组协议。参见图8,NC协议位于SDU重组之后。参见图9,所述NC协议位于去RLC包头之后,以及SDU重组之前。
结合图10进行示例性说明,图10中对应了RLC为AM传输模式,其中右侧为第二RLC实体,NC即NC协议,NC协议位于SDU重组之后。
所述第二RLC实体中对所述NC协议得到的所述第二输出结果不执行的处理包括以下至少之一:SDU重组、去RLC包头。其中,所述第二RLC实体中对所述NC协议处理得到的所述第二输出结果不执行的处理,与所述NC协议在所述第二RLC实体中的位置相关。
也就是说,所述NC协议在所述第二RLC实体中所处的位置,会对所述NC协议的第二输出结果所执行的处理有影响,比如,所述NC协议位于去RLC包头之后,则NC协议收到的第二接收数据包为去RLC包头处理后的第一接收数据包,因此针对所述第二输出结果不再执行去RLC包头处理。比如,所述NC协议位于去RLC包头、重组之后,则NC协议收到的第二接收数据包为去RLC包头、重组处理后的第一接收数据包,因此针对所述第二输出结果不再执行去RLC包头、重组处理,并且该第二输出结果直接输入到下一级实体中。
方式3、所述第一协议实体为第二SDAP实体。
具体的,所述终端设备可以包含一个或多个SDAP实体,其中不同的SDAP实体可以对应不同的目标粒度下的不同对象;所述终端设备在接收到所述NC配置信息之后,可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的RLC实体中增加NC协议,而其他RLC实体中不增加NC协议。应理解,本方式中的第二SDAP实体与前述情况一的第一SDAP实体可以相同也可以不同,本实施例不做限定。
举例来说,终端设备可以有4个SDAP实体,其中,SDAP实体1对应了以承载作为目标粒度下的承载1,和SDAP实体2对应了以承载作为目标粒度下的承载2;若所述NC配置信息是针对承载作为 目标粒度下的承载1的配置,则所述终端设备可以确定在承载1所对应的SDAP实体1中包含NC协议,而其他SDAP实体中不包含所述NC协议。
也就是根据NC配置信息确定执行NC的一个或多个SDAP实体中的任意之一称为第二SDAP实体进行后续说明,应理解,若存在执行NC的多个SDAP实体都可以执行NC,则所述执行NC的多个SDAP实体中不同SDAP实体的处理可以为相同的,只是这里不做重复说明。
上述第二SDAP实体还可以替换称为第二SDAP层(layer)或者第二SDAP entity。
基于前述说明,所述第二SDAP实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第二SDAP实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第二NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
在所述第一协议实体为所述第二SDAP实体的情况下,所述第一接收数据包为SDAP协议数据单元PDU。所述NC协议的功能应用于所述SDAP SDU的数据部分,或SDAP SDU,或SDAP PDU的数据部分。也就是说,所述第一接收数据包具体为SDAP SDU的数据部分,或SDAP SDU,或SDAP PDU的数据部分。
和/或,所述NC协议的功能应用于有SDAP包头的SDAP PDU。也就是说,第一接收数据包即所述SDAP PDU为有SDAP包头的SDAP PDU,若该原SDAP PDU中包含SDAP包头,则所述终端设备的第二SDAP实体中包含的NC协议可以对其进行NC处理;若该原SDAP PDU中不包含SDAP包头,则所述终端设备的第二SDAP实体中包含的NC协议可以不对其进行NC处理。
应理解,上述两种实施方式可以结合使用,比如,所述NC协议的功能应用于有SDAP包头的SDAP PDU的数据部分。
本处理方式中,所述NC协议在所述第二SDAP实体中的位置也可以是根据实际情况进行设置的,比如,所述NC协议位于所述第二SDAP实体中的映射服务质量数据流QoS flow到DRB的协议之后,或,移除SDAP包头的协议之后。比如,参见图11,NC协议即图11中的NC,发送SDAP实体即本实施例中的第二SDAP实体,该NC协议在图11示意出的位置为移除SDAP包头之后。
所述NC协议在所述第二SDAP实体中所处的位置,会对所述NC协议的第二输出结果所执行的处理相关,比如,所述NC协议位于映射服务质量数据流QoS flow到DRB的协议之后,则NC协议收到的第二接收数据包为映射服务质量数据流QoS flow到DRB处理后的第一接收数据包,所述第二SDAP实体中针对所述第二输出结果不再执行映射服务质量数据流QoS flow到DRB的处理。比如,所述NC协议位于移除DSAP包头之后,则NC协议收到的第二接收数据包为映射服务质量数据流QoS flow到DRB、移除DSAP包头处理后的第一接收数据包,因此所述第二SDAP实体中针对所述第二输出结果不再执行映射服务质量数据流QoS flow到DRB、移除DSAP包头的处理;并且该第二输出结果可以直接输入到该第二SDAP实体的下一个实体。
方式4、所述第一协议实体为第二MAC实体。
具体的,所述终端设备可以包含一个或多个MAC实体,其中不同的MAC实体可以对应不同的目标粒度下的不同对象;所述终端设备在接收到所述NC配置信息之后,可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的MAC实体中增加NC协议,而其他MAC实体中不增加NC协议。应理解,本方式中的第二MAC实体与前述情况一的第一MAC实体可以相同也可以不同,本实施例不做限定。
举例来说,终端设备可以有4个MAC实体,所述NC配置信息为针对MAC实体为目标粒度下的MAC实体1的配置,则所述终端设备可以MAC实体1中包含NC协议,而其他MAC实体中不包含所述NC协议。
也就是根据NC配置信息确定执行NC的一个或多个MAC实体中的任意之一称为第二MAC实体进行后续说明,应理解,若存在执行NC的多个MAC实体都可以执行NC,则所述执行NC的多个MAC实体中不同MAC实体的处理可以为相同的,只是这里不做重复说明。
上述第二MAC实体还可以替换称为第二MAC层(layer)或者第二MAC entity。
基于前述说明,所述第二MAC实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第二MAC实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实 体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第二NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
在所述第一协议实体为所述第二MAC实体的情况下,所述第一接收数据包为MAC PDU。
在一种实施方式中,所述NC协议的功能应用于所述MAC SDU的数据部分,或MAC SDU,或MAC PDU的数据部分。也就是说,在所述第二MAC实体中NC协议用于对所述SDAP PDU的数据部分进行处理,或者,在所述第二MAC实体中的NC协议用于对MAC SDU进行处理,或者,在所述第二MAC实体中的NC协议用于对MAC SDU的数据部分进行处理。
本处理方式中,所述NC协议在所述第二MAC实体中的位置也可以是根据实际情况进行设置的,比如,所述NC协议位于所述第二MAC实体中的以下子层之一的之前或之后:逻辑信道优先级协议、解复用协议,HARQ进程协议。比如,比如,参见图12,图12中右侧为上述第二MAC实体,NC协议即图12中的NC,该NC协议在图12示意出的位置为HARQ进程(即HARQ进程协议)之后,复用(即复用协议)之前。
所述第二MAC实体中对所述NC协议处理得到的所述第一输出结果不执行的处理,与所述NC协议在所述第二MAC实体中的位置相关。比如,所述NC协议位于解复用协议之后,则NC协议收到的第二接收数据包为HARQ、复用处理后的第一接收数据包,因此所述第二MAC实体中针对所述第二输出结果不再执行HARQ和解复用的处理。比如,所述NC协议位于HARQ之前,则NC协议收到的第二接收数据包为从上一个实体直接传输来的第一接收数据包,因此所述第二MAC实体中针对所述第二输出结果需要执行逻辑信道优先级、解复用以及HARQ处理。比如,所述NC协议位于逻辑信道优先级之后,则NC协议收到的第二接收数据包为逻辑信道优先级、解复用以及HARQ处理后的第一接收数据包,因此所述第二MAC实体中针对所述第二输出结果不再执行逻辑信道优先级、解复用以及HARQ处理;并且该第二输出结果直接输入到第二MAC实体的下一个实体。
可见,通过采用上述方案,就可以在第一协议实体中添加网络编码协议,如此可以使得在通信网络的协议层的任意一个协议实体中支持网络编码功能,从而通过在协议实体中增加网络编码功能,可以在利用更少的传输资源的情况下,提升数据传输的可靠性,保证整体的处理效率。
图13是根据本申请一实施例的数据处理方法的示意性流程图。该方法可选地可以应用于图1所示的系统,但并不仅限于此。该方法包括以下内容的至少部分内容。
S1310、网络设备的第二协议实体对数据包进行处理,得到处理后的数据包;其中,所述第二协议实体中包含网络编码(NC,Network Coding)协议。

上述NC使能的标识可以包括第一标识或第二标识;所述第一标识可以表示NC使能或者开启NC协议,或者使用NC协议功能;第二标识可以表示不使用NC功能,或者不使用NC协议功能,或不使用NC协议等等。其中,所述第一标识可以为1,第二标识可以为0;或者所述第一标识为“enable”,第二表示为“disable”,这里不对其进行穷举。
所述NC协议采用的编码方式的标识(比如表示为coding profile id),还可以称为NC协议采用的编码协议的标识。具体的,所述编码方式的标识(或编码协议的标识)可以用于表示NC协议使用的NC算法所对应的标识。举例来说,NC算法-1对应的编码方式的标识(或编码协议的标识)为01,NC算法-2对应的编码方式的标识(或编码协议的标识)为02等等。
所述NC协议支持分段(segment)的最大长度L,L为大于等于2的整数,其中,所述NC协议支持分段的最大长度指的是:NC协议支持分段且每个分段的长度均为L。L的单位可以是bit或者byte等等。对分段的最大长度进行配置是由于需要NC协议处理的比特流的长度要求一致。
所述NC协议支持的最大分段个数,指的是:NC协议支持分段且分段的数量不可超过上述最大分段个数。
所述NC协议支持的数据流数量,也就是说,NC协议支持的数据流的数量可以是一个或多个。
所述NC协议支持的数据包处理数量N,这里N可以根据实际情况设置,比如可以为大于等于2的整数,假设N等于2,也就是说每次针对2个数据包进行NC处理,若支持的数据流的数量为1个,则可以针对该数据流中的每两个数据包进行NC;若支持的数据流数量为2个或更多,可以是将每两个数据流分别包含的数据包进行NC。
所述NC协议支持的NC算法具体可以为所述NC协议支持的NC算法的名称,比如,喷泉码,当然所述NC算法还可以有其他算法,只是本实施例不对其进行穷举。
应理解,上述NC配置信息可以包含以上内容中可以仅包含部分内容,也可以包含全部内容。示例性的,在NC配置信息中可以仅包括:NC协议采用的编码方式的标识、NC协议支持分段的最大长度L;这种情况下,其他的NC配置可以采用默认配置。
所述NC配置信息由以下至少之一携带:无线资源控制(RRC,Radio Resource Control)配置、小区配置、分组数据汇聚协议(PDCP,Packet Data Convergence Protocol)配置、无线承载配置、无线链路控制(RLC,Radio Link Control)配置、介质访问控制(MAC,Medium Access Control)配置、逻辑信道配置。
需要指出的是,上述NC配置信息可以是在上述信息任意之一中携带,比如,在RRC配置中携带;并且若在其中任意之一携带的情况下,可以在其他信息中不携带,也就是说NC配置信息仅需要通过上述信息任意之一传输一次即可。
还需要指出,若NC配置信息需要更改,比如,网络设备需要采用新的NC编码方式进行NC处理,此时可以发送更新后的新的NC配置信息,该新的NC配置信息可以与上一次发送的NC配置信息分别采用不同的信息携带,比如,上一次发送的NC配置信息由MAC配置携带,新的NC配置信息可以由PDCP配置携带,可以由网络设备根据实际情况来确定,这里不对其进行限定。
所述NC配置信息为目标粒度下的至少部分对象的配置;其中,所述目标粒度为以下至少之一:承载、PDCP实体、RLC实体、NC实体、、小区、MAC实体。
其中,所述目标粒度下的至少部分对象中,所述对象可以与所述目标粒度相关,比如,所述目标粒度为承载,相应的,所述目标粒度下的至少部分对象可以指的是承载粒度下的一个或多个承载;再比如,所述目标粒度为,相应的,所述目标粒度下的至少部分对象指的是一个或多个。
上述目标粒度可以是一个或多个,比如,目标粒度为承载和小区,相应的,目标粒度下的至少部分对象可以指的是一个或多个小区下的一个或多个承载。
还需要指出,所述NC配置信息中还可以包含所述目标粒度以及所述目标粒度下的至少部分对象;比如,在所述NC配置信息中可以指示目标粒度为承载,目标粒度下的至少部分对象为承载的编号(或称为序号或索引号),比如在所述NC配置信息中包含:NC协议的目标粒度为承载,NC协议应用于承载-1、承载-2;再比如,在所述NC配置信息中可以指示目标粒度为承载和,目标粒度下的至少部分对象为承载的编号(或称为序号或索引号)以及的标识(比如的IMSI),比如在所述NC配置信息中包含:NC协议的目标粒度为承载和,NC协议应用于A和B,以及承载-1和承载-2。
上述仅以目标粒度为承载、、小区中至少之一做了示例性说明,不作为所述NC配置信息的目标粒度及其对应的至少部分对象的限定,实际处理中可以设置其他目标粒度及其对应的至少部分对象,只是这里不做穷举。
进一步地,所述第二协议实体在与目标粒度下至少部分对象的所述NC配置信息对应的情况下,存在所述NC协议。
前述已经说明NC配置信息可以是针对目标粒度下的至少部分对象的配置。
具体的,所述网络设备可以包含一个或多个第二协议实体,其中不同的第二协议实体可以对应不同的目标粒度下的不同对象;可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的第二协议实体中增加NC协议,而其他第二协议实体中不增加NC协议。
另外,所述NC配置信息还可以为针对全部小区下的全部的配置,也就是可以不划分目标粒度,此时,接收到该NC配置的可以在全部第二协议实体中均增加NC协议。
上述NC协议用于执行NC发送功能和/或NC接收功能;和/或,所述NC协议用于执行网络编码功能和/或网络解码功能。
具体来说,所述NC协议用于执行NC发送功能,与所述NC协议在所述第二协议实体中的位置相关。若所述NC协议为所述第二协议实体中间层的协议,则所述NC协议用于执行NC发送功能具体可以指的是:所述NC协议向所述第二协议实体中位于NC协议的下一层协议发送数据的功能。若所述NC协议为所述第二协议实体中的最后一层协议,则所述NC协议用于执行NC发送功能具体可以指的 是:所述NC协议在所述第二协议实体中,向位于第二协议实体之后的下一个协议实体发送数据的功能。
所述NC协议用于执行NC接收功能,与所述NC协议在所述第二协议实体中的位置相关。若所述NC协议为所述第二协议实体中间层的协议,则所述NC协议用于执行NC接收功能具体可以指的是:所述NC协议从所述第二协议实体中位于NC协议的上一层协议接收数据的功能。若所述NC协议为所述第二协议实体中的第一层协议,则所述NC协议用于执行NC接收功能具体可以指的是:所述NC协议在所述第二协议实体中,从位于第二协议实体之前的上一个协议实体接收数据的功能。
所述NC协议用于执行网络编码功能,可以为:所述NC协议位于发送端的情况下,所述NC协议用于执行网络编码功能。
所述NC协议用于执行网络解码功能,可以为:所述NC协议位于接收端的情况下,所述NC协议用于执行网络解码功能。
上述发送端或接收端是针对数据流向或走向而言的,所述网络设备可以即为发送端也为接收端,比如所述网络设备发送下行数据的时候可以为发送端;所述网络设备接收上行数据为接收端。
需要指出若网络设备为发送端的情况下,所述NC协议可以执行NC接收功能、网络编码功能以及NC发送功能;所述网络设备为接收端的情况下,所述NC协议可以执行NC接收功能、网络解码功能以及NC发送功能。
再进一步地,所述NC协议对应第一NC实体;所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理。
具体的,所述第一NC实体可以具备上述NC发送功能、NC接收功能、网络编码功能、网络解码功能中全部功能的实体。
或者,所述NC协议对应第二NC实体和第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。
具体的,所述第二NC实体可以指的是具备上述NC发送功能、NC接收功能、网络解码功能中全部功能的实体;所述第三NC实体可以具备上述NC发送功能、NC接收功能、网络编码功能全部功能的实体。
也就是说,NC协议可以对应一个收发共用的第一NC实体,或者NC协议可以对应一个第二NC实体以及一个第三NC实体,该第二NC实体用于对接收到的数据包进行处理,该第三NC实体用于对待传输数据包进行处理。
上述第一NC实体可以称为第一NC instance;所述第二NC实体可以称为第二NC instance;所述第三NC实体可以称为第三NC instance。
上述S1310中,所述网络设备的第二协议实体对数据包进行处理,得到处理后的数据包,以将网络设备作为接收端或发送端分别来进行说明,具体如下:

应理解,若所述第二协议实体中NC协议位于中间层,则所述第四待传输数据包具体可以指的是:所述第三输入信息至少包含所述待传输数据包在所述NC协议之前的其他协议处理后的第三待传输数据包。或者,若所述第二协议实体中NC协议位于第一层,则所述第四待传输数据包可以指的是:所述第三输入信息包含上一个协议实体发来的所述第三待传输数据包。

所述第三输入信息与所述NC配置信息所对应的所述目标粒度下的至少部分对象相关。也就是说,所述第三输入信息可以对应于目标粒度下的至少部分对象。前述已经说明所述NC配置信息可以为目标粒度下的至少部分对象的配置;相应的,在所述第三输入信息中也可以是对应了目标粒度下的至少部分 对象。
比如,目标粒度为承载,目标粒度下的至少部分对象包含了承载1和承载2,则所述第三输入信息中包含的第四待传输数据包具体为承载1以及承载2的第三待传输数据包或处理后的第三待传输数据包。再比如,目标粒度为RLC实体,目标粒度下的至少部分对象包含RLC实体1,则所述第三输入信息中包含的第四待传输数据包具体为对应RLC实体1的第三待传输数据包或处理后的第三待传输数据包。
上述第二协议实体中的所述NC协议执行分段处理为预定义的;和/或,所述第二协议实体中的所述NC协议执行填充处理为预定义的。
也就是说,所述NC协议中是否执行所述分段处理,可以是预定义的,比如可以默认针对每个待传输数据包均执行分段处理或均不执行分段处理。
所述NC协议中是否执行所述填充处理,可以是预定义的,比如可以默认针对每个待传输数据包均执行填充处理或均不执行填充处理。
本情况中所述网络设备为发送端,相应的,所述NC协议执行的NC算法处理具体可以为网络编码处理。
所述NC协议还用于接收所述第二协议实体中位于所述NC协议之前的协议发来的处理后的第三待传输数据包,将所述处理后的第三待传输数据包作为所述第四待传输数据包;以及将所述第三输出结果递交至所述第二协议实体中的下一层协议。也就是说,所述NC协议位于所述第二协议实体的中间的情况下,所述NC协议接收到的是其在所述第二协议实体中的前一层或前多层协议处理后的第三待传输数据包,将所述处理后的第三待传输数据包作为所述第四待传输数据包;通过所述NC协议执行前述处理至少之一之后,得到所述第三输出结果;将该第三输出结果递交至所述第二协议实体的下一层协议。
或者,所述NC协议还用于接收位于所述第二协议实体之前的实体发来的第三待传输数据包,将所述第三待传输数据包作为所述第四待传输数据包;以及将所述第三输出结果递交至所述第二协议实体中的下一层协议。也就是说,所述NC协议位于所述第二协议实体的第一层的情况下,所述NC协议接收到的是所述第二协议实体之前的实体发来的第三待传输数据包,将所述第三待传输数据包作为所述第四待传输数据包;通过所述NC协议执行前述处理至少之一之后,得到所述第三输出结果;将该第三输出结果递交至所述第二协议实体的下一层协议。
或者,所述NC协议还用于接收所述第二协议实体中位于所述NC协议之前的协议发来的处理后的第三待传输数据包,将所述处理后的第三待传输数据包作为所述第四待传输数据包;以及将所述第三输出结果递交至所述第二协议实体的下一个实体。也就是说,所述NC协议位于所述第二协议实体的中间的情况下,所述NC协议接收到的是其在所述第二协议实体中的前一层或前多层协议处理后的第三待传输数据包,将所述处理后的第三待传输数据包作为所述第四待传输数据包;通过所述NC协议执行前述处理至少之一之后,得到所述第三输出结果;将该第三输出结果递交至所述第二协议实体的下一个实体。
进一步地,在基于上述NC协议对第三输入信息执行处理得到第三输出结果之后,所述第二协议实体还可以在最终得到的第三数据包中携带第一指示信息。
具体的,所述第三数据包中携带第一指示信息;所述第一指示信息中包括以下至少之一:

其中,所述是否执行NC的指示可以包含第一指示值或第二指示值,所述第一指示值可以用于表示所述第三数据包未执行NC处理,第二指示值可以用于表示所述第三数据包执行NC处理。进一步地, 若所述第三数据包是否执行NC的指示表示所述第三数据包未执行NC,则所述第一指示信息中可以不包含其他信息。若所述第三数据包是否执行NC的指示表示所述第三数据包执行NC,则所述第一指示信息中可以包含其他信息。
所述NC协议采用的编码方式的标识可以是本次进行NC处理所采用的编码方式的标识,比如可以支持3种编码方式,本次使用了编码方式2,则所述NC协议采用的编码方式的标识具体为编码方式2。
所述NC协议支持的NC算法可以是本次进行NC处理所采用的NC算法,比如可以支持3种NC算法,本次使用了NC算法1,则所述NC协议采用的NC算法具体可以为NC算法1的具体名称。
所述NC协议支持分段的最大长度L,可以指的是所述NC配置信息中携带的NC协议支持分段的最大长度L。
所述NC协议支持的最大分段个数,可以指的是所述NC配置信息中携带的NC协议支持的最大分段个数。
所述NC协议支持的数据流数量可以是本次对几个数据流进行了NC处理,比如所述NC协议对2个数据流的待传输数据包进行NC处理。
所述NC协议支持的数据包处理数量N可以是所述NC配置信息中携带的NC协议支持的数据包处理数量N。
所述是否执行分段的指示用于表示本次NC处理是否执行分段,比如,可以采用指示值的方式来表示,若指示为1则可以表示本次NC处理执行分段,否则表示本次NC处理未执行分段。
所述分段的实际长度,可以指的是本次进行NC处理进行分段的长度,该分段的长度可以是小于或等于所述NC配置信息中携带的NC协议支持分段的最大长度L。
所述分段的实际个数,可以指的是本次进行NC处理分段的个数,可以小于或等于所述NC配置信息中携带的NC协议支持的最大分段个数,比如NC配置信息中携带的NC协议支持的最大分段个数为20,则所述分段的实际个数可以为10个。
所述第三数据包是否为NC的首个分段的指示,也就是说,在前述是否执行分段的指示中若表征本次执行分段的情况下,可以在所述第三数据包中携带其是否为NC的第一个分段的指示;比如,具体可以为一个标志值,若为1可以表示该第三数据包为NC的首个分段数据包。
所述第三数据包是否为NC的最后一个分段的指示,也就是说,在前述是否执行分段的指示中若表征本次执行分段的情况下,可以在所述第三数据包中携带其是否为NC的最后一个分段数据包的指示;比如,具体可以为一个标志值,若为1可以表示该第三数据包为NC的最后一个分段。
所述第三数据包是否携带填充的指示可以为一个指示值,比如若为1可以表示第三数据包携带填充,否则表示第三数据包不携带填充;或者,还可以为其他指示方式,比如可以直接写入“padding”这样的指示信息来表示第三数据包携带填充,当然还可能有其他指示方式,只是这里不进行穷举。
所述第三数据包填充的长度,可以是在前述第三数据包是否携带填充的指示表征所述第三数据包携带填充的情况下存在的内容,所述第三数据包填充的长度具体可以为bit或byte值,比如包含了8bit的填充,或32bit的填充等等。
所述是否执行重组的指示可以用于指示接收端(比如终端设备)在接收到该第三数据包的情况下是否对所述第三数据包及其他分段数据包进行重组;具体可以为一个指示值,比如若为1的情况下,用于指示接收端在接收到该第三数据包的情况下对所述第三数据包及其他分段数据包进行重组,否则不进行重组;又或者,可以为一个具体的指示信息比如“reassembly”来指示接收端(比如终端设备)在接收到该第三数据包的情况下对所述第三数据包及其他分段数据包进行重组。
所述是否执行去填充的指示以用于指示接收端(比如终端设备)在接收到该第三数据包的情况下是否对所述第三数据包进行去填充处理;具体可以为一个指示值,比如若为1的情况下,用于指示接收端在接收到该第三数据包的情况下对所述第三数据包进行去填充处理,否则不进行去填充处理;又或者,可以为一个具体的指示信息比如“去填充”来指示接收端在接收到该第三数据包进行去填充处理。
应理解,在实际发送的第一指示信息中可以包含上述全部内容,又或者可以仅包含其中一个或多个内容。
所述第一指示信息在所述第三数据包的以下部分之一携带:所述第三数据包的包头、所述第三数据包的有效载荷部分、所述第三数据包的新包头。
其中,所述第三数据包的包头与所述第三数据包的新包头不同之处在于,所述第三数据包的新包头可以为新构建的一个包头的格式(format),而所述第三数据包的包头则可以指的是第三数据包原格式下的包头中的某一个字段中携带所述第一指示信息。
所述第三数据包具体为哪种类型的数据包与所述第二协议实体相关,比如第二协议实体为PDCP实体,则所述第三数据包可以为PDCP PDU,该PDCP PDU通过以下之一携带上述第一指示信息:所 述PDCP PDU的包头、所述PDCP PDU的有效载荷(payload)部分、所述PDCP PDU的新包头。比如第二协议实体为RLC实体,则所述第三数据包可以为RLC PDU,该RLC PDU通过以下之一携带上述第一指示信息:所述RLC PDU的包头、所述RLC PDU的有效载荷(payload)部分、所述RLC PDU的新包头。比如,第二协议实体为SDAP实体,则所述第三数据包可以为SDAP PDU,该SDAP PDU通过以下之一携带上述第一指示信息:所述SDAP PDU的包头、所述SDAP PDU的有效载荷(payload)部分、所述SDAP PDU的新包头。再比如,第二协议实体为MAC实体,则所述第三数据包可以为MAC PDU,该MAC PDU通过以下之一携带上述第一指示信息:所述MAC PDU的包头、所述MAC PDU的有效载荷(payload)部分、所述MAC PDU的新包头。以上仅为示例性说明,本实施例不做穷举。
应理解,上述第二协议实体具体可以为PDCP实体、RLC实体、SDAP实体、MAC实体中任意之一。还应理解的是,在本情况一中所述NC协议中执行的NC算法处理具体指的是网络编码处理。本情况中,所述第三待传输数据包可以指的为所述网络设备待传输的下行数据包。
针对上述情况一,下面分别结合所述第二协议实体为不同类型的实体的处理方式进行说明:
方式1、所述第二协议实体为第三PDCP实体。
具体的,可以包含一个或多个PDCP实体,其中不同的PDCP实体可以对应不同的目标粒度下的不同对象;可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的PDCP实体中增加NC协议,而其他PDCP实体中不增加NC协议。
也就是根据NC配置信息确定执行NC的一个或多个PDCP实体中的任意之一称为第三PDCP实体进行后续说明,应理解,若存在执行NC的多个PDCP实体都可以执行NC,则所述执行NC的多个PDCP实体中不同PDCP实体的处理可以为相同的,只是这里不做重复说明。
上述第三PDCP实体还可以替换称为第三PDCP层(layer)或者第三PDCP entity。上述NC协议还可以替换性的称为NC功能、NC功能模块等等,本实施例不对其进行穷举。
基于前述说明,所述第三PDCP实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第三PDCP实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第三NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
其中,所述NC协议子层的功能应用于目标数据承载DRB的所述第四待传输数据包和/或目标信令承载SRB的所述第四待传输数据包。
前述已经说明所述第二协议实体在与目标粒度下至少部分对象的所述NC配置信息对应的情况下,存在所述NC协议子层;也就是说,在第三PDCP实体中的NC协议可以是基于NC配置信息的目标粒度下的至少部分对象所配置的。所述目标粒度若为承载,该目标粒度下的至少部分对象为目标DRB和/或目标SRB;该目标DRB可以为一个或多个,目标SRB也可以为一个或多个。比如,一个DRB1(即目标DRB)对应所述第三PDCP实体,所述第三PDCP实体中的NC协议会对该DRB1的第四待传输数据包进行NC处理。
在所述第二协议实体为所述第三PDCP实体的情况下,所述第三数据包为PDCP协议数据单元(PDU,Protocol Data Unit);所述第四待传输数据包可以为:PDCP SDU或PDCP PDU的数据部分。相应的,所述NC协议的功能应用于所述PDCP PDU的数据部分,或者,所述NC协议子层的功能应用于所述PDCP PDU的PDCP SDU。也就是说,在所述第三PDCP实体中NC协议用于对所述PDCP PDU的数据部分进行处理,或者,在所述第三PDCP实体中的NC协议用于对PDCP PDU的PDCP SDU进行处理。
其中,所述PDCP SDU为所述第四待传输数据包,而经过所述第三PDCP实体的NC协议对该PDCP SDU即第四待传输数据包进行处理之后,在所述第三PDCP实体发出的所述第三数据包即为PDCP PDU。所述PDCP PDU可以是在所述PDCP SDU的基础上封装得到的。
所述PDCP PDU还可以分为PDCP数据PDU或PDCP控制PDU。一种优选示例中,本实施例提供的方案尤其适用于所述PDCP PDU为PDCP数据PDU。当然,本实施例提供的方案并不排除可以应用于PDCP控制PDU中,只是这里不进行穷举。
或者,所述NC协议的功能应用于以下数据单元之外的其他数据单元:服务数据适配协议SDAP控制PDU和/或SDAP包头。也就是说,本实施例提供的方案中,对上述数据单元不执行NC处理。若第四待传输数据包包含除上述数据单元之外的数据单元的情况下,则可以执行NC处理,比如,第四待传输数据包为SDAP的数据PDU的情况下,可以对其执行NC处理。当然,还可以包含其他情况,这里不进行穷举。
所述第三数据包中还携带所述第三数据包的序列号(SN,Sequence Number)。该SN号可以适用于对端能够得知所述第三数据包为执行NC操作的第几个分段数据包,或者,适用于对端能够得知所述第三数据包是哪个原数据包的分段和/或是不是原数据包的分段,进而可以便于接收端(即对端,也就是终端设备)能够进行级联或重组处理。
本处理方式中,所述NC协议在所述第三PDCP实体中的位置也可以是根据实际情况进行设置的,分别来说:
所述NC协议位于所述第三PDCP实体中的第一协议之后;其中,所述第一协议为以下之一:头压缩协议、完整性保护协议、加密协议。
和/或,所述NC协议位于所述第三PDCP实体中的第二协议之前;其中,所述第二协议为以下之一:头压缩协议、完整性保护协议、加密协议、加PDCP头协议。
可选的,NC协议位于所述第三PDCP实体中的加PDCP头协议之后。此时,需要重新执行生成PDCP包头、分段等处理至少之一。
结合图4-图7进行示例性说明,在图4-图7中,发送PDCP实体为前述第三PDCP实体;网络编码(NC)即前述NC协议,头压缩即前述头压缩协议(或可以称为头压缩实体、头压缩协议子层、头压缩层等等这里不做穷举),完整性保护即前述完整性保护协议(或可以称为完整性保护实体、完整性保护协议子层、完整性保护层等等这里不做穷举),加密即前述加密协议(或可以称为加密实体、加密协议子层、加密层等等这里不做穷举),加PDCP头即前述加PDCP头协议(或可以称为加PDCP头实体、加PDCP头协议子层、加PDCP头层等等这里不做穷举)。
参见图4,NC即NC协议,该NC协议位于第二协议之前,所述第二协议为图4中的头压缩。参见图5和图6,第二协议为图5中的完整性保护,所述NC协议位于所述完整性保护协议之前,或者第一协议为图5或图6中的头压缩,所述NC协议位于头压缩协议之后。参见图7,第二协议为图7中的加密,所述NC协议位于所述加密协议之前,或者第一协议为图7中的完整性保护,则所述NC协议位于完整性保护协议之后。
所述第三PDCP实体中对所述NC协议得到的所述第三输出结果不执行的处理包括以下至少之一:头压缩、完整性保护、加密。其中,所述第三PDCP实体中对所述NC协议处理得到的所述第三输出结果不执行的处理,与所述NC协议在所述第三PDCP实体中的位置相关。
也就是说,所述NC协议在所述第三PDCP实体中所处的位置,会对所述NC协议的第三输出结果所执行的处理相关,比如,所述NC协议位于完整性保护协议之前、且位于头压缩协议之后,则NC协议收到的第四待传输数据包为头压缩处理后的第三待传输数据包,因此针对所述第三输出结果不再执行头压缩处理。比如,所述NC协议位于完整性保护协议之后、且位于加密协议之前,则NC协议收到的第四待传输数据包为头压缩以及完整性保护处理后的第三待传输数据包,因此针对所述第三输出结果不再执行头压缩处理以及完整性保护处理。再比如,所述NC协议位于加密协议之后、且添加PDCP包头协议之前,则NC协议收到的第四待传输数据包为头压缩、完整性保护、加密处理后的第三待传输数据包,因此针对所述第三输出结果不再执行头压缩、完整性保护、加密处理。
方式2、所述第二协议实体为第三RLC实体。
具体的,可以包含一个或多个RLC实体,其中不同的RLC实体可以对应不同的目标粒度下的不同对象;可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的RLC实体中增加NC协议,而其他RLC实体中不增加NC协议。
也就是根据NC配置信息确定执行NC的一个或多个RLC实体中的任意之一称为第三RLC实体进行后续说明,应理解,若存在多个RLC实体都可以执行NC,则所述执行NC的多个RLC实体中不同RLC实体的处理可以为相同的,只是这里不做重复说明。
上述第三RLC实体还可以替换称为第三RLC层(layer)或者第三RLC entity。
基于前述说明,所述第三RLC实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第三RLC实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第三NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
所述RLC可以存在UM(非确认,Un-Acknowledged mode)、AM(确认,Acknowledged mode)以及TM(transport mode,透传模式)三种传输模式,比如,所述NC协议的功能应用于RLC非确认模式UM传输的所述第四待传输数据包和/或RLC确认模式AM传输的所述第四待传输数据包。其中,所 述NC协议针对RLC的哪种模式传输的第四待传输数据包进行处理,可以是预定义的,或网络设备配置的(比如通过NC配置信息中携带,或其他信息中携带)。
所述第三RLC实体为双向(bi-directional)RLC实体或单向(unidirectional)RLC实体。也就是说,所述NC协议针对哪种类型的RLC实体中传输的待传输数据包进行处理,可以是预定义的,或网络设备配置的(比如通过NC配置信息中携带,或其他信息中携带)。应理解上述仅为示例性说明,实际可以针对全部RLC实体类型均进行处理,只是不做穷举。
在所述第二协议实体为所述第三RLC实体的情况下,所述第三数据包为RLC协议数据单元PDU。
所述NC协议的功能应用于所述RLC PDU的数据部分,或RLC SDU,或RLC SDU的数据部分。也就是说,所述第四待传输数据包具体为RLC PDU的数据部分,或者,RLC SDU,或者,RLC SDU的数据部分。
其中,所述RLC PDU的RLC SDU可以理解为所述RLC SDU为所述待传输数据包,而经过所述第三RLC实体的NC协议对该RLC SDU处理之后,在所述第三RLC实体发出的所述第三数据包即为RLC PDU。所述RLC PDU可以是在所述RLC SDU的基础上封装得到的。
其中,所述第三数据包中还携带所述第三数据包的序列号(SN,Sequence Number)。也就是说,在所述RLC PDU中还可以携带SN号。该SN号可以适用于对端能够得知所述第三数据包为执行NC操作的第几个数据包,进而可以便于接收端(即对端)能够进行级联或重组处理。比如,在所述第三数据包也就是RLC PDU中携带的第一指示信息可以指示所述第三数据包是否为NC的首个分段的指示,若该指示为否,则所述第三数据包为NC的多个分段中之一;相应的,对端可以基于该第三数据包的序列号以及当前缓存的从NC首个分段数据包进行重组处理。
本处理方式中,所述NC协议在所述第三RLC实体中的位置也可以是根据实际情况进行设置的,比如:
所述NC协议位于所述第三RLC实体中的第三协议之前;所述第三协议包括以下之一:生成RLC包头并存储在待传输缓存协议,分段和修改RLC包头协议,添加RLC包头协议。
和/或,所述NC协议位于所述第三RLC实体中的第四协议之后;所述第四协议包括以下之一:生成RLC包头并存储在待传输缓存协议,分段和修改RLC包头协议。
可选的,NC协议位于所述第三RLC实体中的添加RLC头协议之后。此时,需要重新执行生成RLC包头、分段等处理至少之一。
具体的可以为:
所述NC协议位于所述第三RLC实体中的生成RLC包头并存储在待传输缓存协议之前;
或者,
所述NC协议位于所述第三RLC实体中的生成RLC包头并存储在待传输缓存协议之后,以及分段和修改RLC包头协议之前;
或者,
所述NC协议位于分段和修改RLC包头协议之后,以及添加RLC包头协议之前。
结合图8-图9进行示例性说明,图8-图9中发送UM-RLC实体(entity)即前述第三RLC实体;NC即NC协议,生成RLC包头并存储在待传输缓存即前述生成RLC包头并存储在待传输缓存协议,分段和修改RLC包头即前述分段和修改RLC包头协议,添加RLC包头即前述添加RLC包头协议。参见图8,NC协议位于生成RLC包头并存储在待传输缓存之前。参见图9,所述NC协议位于生成RLC包头并存储在待传输缓存之后,以及分段和修改RLC包头之前。
结合图10进行示例性说明,图10中对应了RLC为AM传输模式,其中左侧为第三RLC实体,NC即NC协议,生成RLC包头并存储在待传输缓存即前述生成RLC包头并存储在待传输缓存协议,分段和修改RLC包头即前述分段和修改RLC包头协议,添加RLC包头即前述添加RLC包头协议。参见图10,NC协议位于生成RLC包头并存储在待传输缓存之前。
应理解,上述仅为示例性说明,不作为限定。
所述第三RLC实体中对所述NC协议得到的所述第三输出结果不执行的处理包括以下至少之一:生成RLC包头并存储在待传输缓存、分段和修改RLC包头、添加RLC包头。其中,所述第三RLC实体中对所述NC协议处理得到的所述第三输出结果不执行的处理,与所述NC协议在所述第三RLC实体中的位置相关。
也就是说,所述NC协议在所述第三RLC实体中所处的位置,会对所述NC协议的第三输出结果所执行的处理相关,比如,所述NC协议位于分段和修改RLC包头之前、且位于生成RLC包头并存储在待传输缓存协议之后,则NC协议收到的第四待传输数据包为生成RLC包头并存储在待传输缓存处理后的第三待传输数据包,因此针对所述第三输出结果不再执行生成RLC包头并存储在待传输缓存处 理。
或者,需要重新执行生成RLC包头和/或并存储在待传输缓存处理。比如,所述NC协议位于分段和修改RLC包头之后、且位于添加RLC包头之前,则NC协议收到的第四待传输数据包为生成RLC包头并存储在待传输缓存、分段和修改RLC包头处理后的第三待传输数据包,因此针对所述第三输出结果不再执行生成RLC包头并存储在待传输缓存、分段和修改RLC包头处理。
或者,针对所述第三输出结果还需执行生成RLC包头并存储在待传输缓存、分段和修改RLC包头处理至少之一的操作(例如若由于NC需要执行分段和修改RLC包头的操作)。比如,所述NC协议位于添加RLC包头之后,则NC协议收到的第四待传输数据包为生成RLC包头并存储在待传输缓存、分段和修改RLC包头、添加RLC包头处理后的第三待传输数据包,因此针对所述第三输出结果不再执行生成RLC包头并存储在待传输缓存、分段和修改RLC包头、添加RLC包头处理,并且该第三输出结果直接输入到下一级实体中。
或者,针对所述第三输出结果还需执行生成修改存储在待传输缓存、分段和修改RLC包头、添加RLC包头处理至少之一的操作(例如若由于NC需要执行分段和修改RLC包头的操作)。
方式3、所述第二协议实体为第三SDAP实体。
具体的,可以包含一个或多个SDAP实体,其中不同的SDAP实体可以对应不同的目标粒度下的不同对象;根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的RLC实体中增加NC协议,而其他RLC实体中不增加NC协议。
也就是根据NC配置信息确定执行NC的一个或多个SDAP实体中的任意之一称为第三SDAP实体进行后续说明,应理解,若存在执行NC的多个SDAP实体都可以执行NC,则所述执行NC的多个SDAP实体中不同SDAP实体的处理可以为相同的,只是这里不做重复说明。
上述第三SDAP实体还可以替换称为第三SDAP层(layer)或者第三SDAP entity。
基于前述说明,所述第三SDAP实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第三SDAP实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第三NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
在所述第二协议实体为所述第三SDAP实体的情况下,所述第三数据包为SDAP协议数据单元PDU。
在一种实施方式中,所述NC协议的功能应用于所述SDAP SDU的数据部分,或SDAP SDU,或SDAP PDU的数据部分。也就是说,在所述第三SDAP实体中NC协议用于对所述SDAP PDU的数据部分进行处理,或者,在所述第三SDAP实体中的NC协议用于对SDAP PDU的SDAP SDU进行处理,或者,在所述第三SDAP实体中的NC协议用于对SDAP SDU的数据部分进行处理。
其中,所述SDAP SDU可以为所述第四待传输数据包,而经过所述第三SDAP实体的NC协议对该SDAP SDU(或者对SDAP SDU的数据部分)处理之后,在所述第三SDAP实体发出的所述第三数据包即为SDAP PDU。所述SDAP PDU可以是在所述SDAP SDU的基础上封装得到的。或者,所述SDAP PDU为所述待传输数据包,经过所述第三SDAP实体的NC协议对该SDAP PDU的数据部分处理之后,在所述第三SDAP实体发出的所述第三数据包即为处理后的SDAP PDU。
在另一实施方式中,所述NC协议的功能应用于有SDAP包头的SDAP PDU。也就是说,待传输数据包可以为原SDAP PDU,若该原SDAP PDU中包含SDAP包头,则的第三SDAP实体中包含的NC协议可以对其进行NC处理;若该原SDAP PDU中不包含SDAP包头,则的第三SDAP实体中包含的NC协议可以不对其进行NC处理。
应理解,上述两种实施方式可以结合使用,比如,所述NC协议的功能应用于有SDAP包头的SDAP PDU的数据部分。
本处理方式中,所述NC协议在所述第三SDAP实体中的位置也可以是根据实际情况进行设置的,比如,所述NC协议位于所述第三SDAP实体中的映射服务质量数据流QoS flow到DRB的协议之后,或,添加SDAP包头协议之前。比如,参见图11,NC协议即图11中的NC,发送SDAP实体即本实施例中的第三SDAP实体,该NC协议在图11示意出的位置为添加SDAP包头(即添加SDAP包头协议)之前,或映射服务质量数据流QoS flow到DRB(即映射服务质量数据流QoS flow到DRB)之后。
所述NC协议在所述第三SDAP实体中所处的位置,会对所述NC协议的第三输出结果所执行的处理相关,比如,所述NC协议位于映射服务质量数据流QoS flow到DRB的协议之后,则NC协议收到的第四待传输数据包为映射服务质量数据流QoS flow到DRB处理后的第三待传输数据包,因此所述第 三SDAP实体中针对所述第三输出结果不再执行映射服务质量数据流QoS flow到DRB的处理。比如,所述NC协议位于添加SDAP包头之后,则NC协议收到的第四待传输数据包为映射服务质量数据流QoS flow到DRB、添加SDAP包头处理后的第三待传输数据包,因此所述第三SDAP实体中针对所述第三输出结果不再执行映射服务质量数据流QoS flow到DRB、添加SDAP包头的处理;并且该第三输出结果可以直接输入到该第三SDAP实体的下一个实体。
或者,在另一种实现方式中,需要重新执行生成SDAP包头、分段等处理至少之一,相应的第三SDAP实体中针对所述第一输出结果还需执行分段、修改SDAP包头、添加SDAP包头至少之一的处理,并将结果输出到该第三SDAP实体的下一个实体。
方式4、所述第二协议实体为第三MAC实体。
具体的,可以包含一个或多个MAC实体,其中不同的MAC实体可以对应不同的目标粒度下的不同对象;根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的MAC实体中增加NC协议,而其他MAC实体中不增加NC协议。
应理解,若存在执行NC的多个MAC实体都可以执行NC,则所述执行NC的多个MAC实体中不同MAC实体的处理可以为相同的,只是这里不做重复说明。
上述第三MAC实体还可以替换称为第三MAC层(layer)或者第三MAC entity。
基于前述说明,所述第三MAC实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第三MAC实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第三NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
在所述第二协议实体为所述第三MAC实体的情况下,所述第三数据包为MAC PDU。
在一种实施方式中,所述NC协议的功能应用于所述MAC SDU的数据部分,或MAC SDU,或MAC PDU的数据部分。也就是说,在所述第三MAC实体中NC协议用于对所述SDAP PDU的数据部分进行处理,或者,在所述第三MAC实体中的NC协议用于对MAC SDU进行处理,或者,在所述第三MAC实体中的NC协议用于对MAC SDU的数据部分进行处理。
本处理方式中,所述NC协议在所述第三MAC实体中的位置也可以是根据实际情况进行设置的,比如,所述NC协议位于所述第三MAC实体中的以下子层之一的之前或之后:逻辑信道优先级协议、复用协议、HARQ进程协议。比如,参见图12,图12中左侧为上述第三MAC实体,NC协议即图12中的NC,该NC协议在图12示意出的位置为HARQ进程(即HARQ进程协议)之前,复用(即复用协议)之后。
可选的,NC协议位于所述第三MAC实体中的生成MAC PDU或加MAC头协议之后。此时,需要重新执行生成MAC包头、分段、重新生成MAC PDU等处理至少之一。
所述第三MAC实体中对所述NC协议处理得到的所述第三输出结果不执行的处理,与所述NC协议在所述第三MAC实体中的位置相关。比如,所述NC协议位于复用协议之后,则NC协议收到的第四待传输数据包为逻辑信道优先级、复用处理后的第三待传输数据包,因此所述第三MAC实体中针对所述第三输出结果不再执行复用的处理。比如,所述NC协议位于逻辑信道优先级之前,则NC协议收到的第四待传输数据包为从上一个实体直接传输来的第三待传输数据包,因此所述第三MAC实体中针对所述第三输出结果需要执行逻辑信道优先级、复用以及HARQ处理。比如,所述NC协议位于HARQ之后,则NC协议收到的第四待传输数据包为逻辑信道优先级、复用以及HARQ处理后的第三待传输数据包,因此所述第三MAC实体中针对所述第三输出结果不再执行逻辑信道优先级、复用以及HARQ处理;并且该第三输出结果直接输入到第三MAC实体的下一个实体。
情况二、网络设备为接收端。
网络设备的第二协议实体对数据包进行处理,得到处理后的数据包,可以包括:网络设备的第二协议实体对接收到的第三接收数据包进行处理,得到第四数据包;其中,所述第二协议实体中的所述NC协议用于对第四输入信息执行以下处理至少之一得到第四输出结果:NC数据缓存、NC分段冗余检测、NC分段删除、重组处理、去填充处理、NC算法处理;其中,所述第四输入信息至少包含第四接收数据包,所述第四接收数据包为所述第三接收数据包或处理后的所述第三接收数据包。

应理解,若所述第二协议实体中NC协议位于中间层,则所述第四接收数据包具体可以指的是:所述第四输入信息至少包含所述第四数据包在所述NC协议前一层或前多层协议处理后的第三接收数据包。
或者,若所述第二协议实体中NC协议位于第一层,则所述第四输入信息至少包含所述第四数据包的相关信息具体可以指的是:所述第三输入信息包含上一个协议实体发来的所述第三接收数据包。

其中,所述第三接收数据包的包头与所述第三接收数据包的新包头不同之处在于,所述第三接收数据包的新包头可以为新构建的一个包头的格式(format),而所述第三接收数据包的包头则可以指的是第三接收数据包原格式下的包头中的某一个字段中携带所述第一指示信息。
应理解,上述第二协议实体具体可以为PDCP实体、RLC实体、SDAP实体、MAC实体中任意之一。还应理解的是,在本情况二中所述NC协议中执行的NC算法处理具体指的是网络解码处理。本情况二中第三接收数据包可以为基于网络设备接收的上行数据包处理得到的数据包。
针对上述情况二,下面分别结合所述第二协议实体为不同类型的实体的处理方式进行说明:
方式1、所述第二协议实体为第四PDCP实体。
具体的,可以包含一个或多个PDCP实体,其中不同的PDCP实体可以对应不同的目标粒度下的不同对象;在接收到所述NC配置信息之后,可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的PDCP实体中增加NC协议,而其他PDCP实体中不增加NC协议。本方式中的第四PDCP实体与前述情况一种的第三PDCP实体可以相同也可以不同。
应理解,若存在执行NC的多个PDCP实体都可以执行NC,则所述执行NC的多个PDCP实体中不同PDCP实体的处理可以为相同的,只是这里不做重复说明。
上述第四PDCP实体还可以替换称为第四PDCP层(layer)或者第四PDCP entity。
基于前述说明,所述第四PDCP实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第四PDCP实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第二NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
其中,所述NC协议的功能应用于数据承载DRB承载的所述第四接收数据包和/或信令承载SRB中承载的所述第四接收数据包。
在第四PDCP实体中的NC协议可以是基于NC配置信息的目标粒度下的至少部分对象所配置的。所述目标粒度若为承载,该目标粒度下的至少部分对象为目标DRB和/或目标SRB;该目标DRB可以为一个或多个,目标SRB也可以为一个或多个。比如,一个DRB1(即目标DRB)对应所述第四PDCP实体,所述第四PDCP实体中的NC协议会对该DRB1的第四接收数据包进行NC处理。
在所述第二协议实体为所述第四PDCP实体的情况下,所述第三接收数据包为PDCP协议数据单元PDU;第四接收数据包可以为PDCP PDU的数据部分,或PDCP SDU。相应的,所述NC协议的功能应用于所述PDCP PDU的数据部分,或者,所述NC协议子层的功能应用于所述PDCP PDU的PDCP SDU。
也就是说,所述第三接收数据包具体为PDCP PDU;在所述第四PDCP实体中NC协议用于对所述PDCP PDU的数据部分进行处理,或者,在所述第四PDCP实体中的NC协议用于对PDCP PDU的PDCP SDU进行处理。
所述PDCP PDU还可以分为PDCP数据PDU或PDCP控制PDU。一种优选示例中,本实施例提供的方案尤其适用于所述PDCP PDU为PDCP数据PDU。当然,本实施例提供的方案并不排除可以应用于PDCP控制PDU中,只是这里不进行穷举。
或者,所述NC协议的功能应用于以下数据单元之外的其他数据单元:服务数据适配协议SDAP控制PDU和/或SDAP包头。也就是说,本实施例提供的方案中,对上述数据单元不执行NC处理。若第四接收数据包包含除上述数据单元之外的数据单元的情况下,则可以执行NC处理,比如,第四接收数据包为SDAP的数据PDU的情况下,可以对其执行NC处理。当然,还可以包含其他情况,这里不进行穷举。
所述第三接收数据包中还携带所述第三接收数据包的SN。也就是说,在所述第四PDCP实体接收到的所述PDCP PDU中还可以携带SN。
本处理方式中,所述NC协议在所述第四PDCP实体中的位置也可以是根据实际情况进行设置的,分别来说:
所述NC协议位于所述第四PDCP实体中的第五协议之前;其中,所述第五协议为以下之一:解头压缩协议、完整性验证协议、解密协议、重排序协议。
和/或,所述NC协议位于所述第四PDCP实体中的第六协议之后;其中,所述第六协议为以下之一:解头压缩协议、完整性验证协议、解密协议、去PDCP头协议、重排序协议。
结合图4-图7进行示例性说明,在图4-图7中,接收PDCP实体为本情况中的第四PDCP实体;网络编码(NC)即前述NC协议,解头压缩即前述解头压缩协议(或可以称为解头压缩实体、解头压缩协议子层、解头压缩层等等这里不做穷举),完整性保护即前述完整性验证协议(或可以称为完整性验证实体、完整性验证协议子层、完整性验证层等等这里不做穷举),解密即前述解密协议(或可以称为解密实体、解密协议子层、解密层等等这里不做穷举),去PDCP头即前述去PDCP头协议(或可以称为去PDCP头实体、去PDCP头协议子层、去PDCP头层等等这里不做穷举)。
参见图4,NC即NC协议,该NC协议位于解头压缩之后。参见图5和图6,所述NC协议位于解头压缩之前,所述完整性验证之后。参见图7,所述NC协议位于所述解密之后,完整性验证之前。
所述第四PDCP实体中对所述NC协议得到的所述第四输出结果不执行的处理包括以下至少之一:解头压缩、完整性验证、解密。其中,所述第四PDCP实体中对所述NC协议处理得到的所述第四输出结果不执行的处理,与所述NC协议在所述第四PDCP实体中的位置相关。
比如,所述NC协议位于完整性验证协议之前、且位于解密协议之后,则NC协议收到的第四接收数据包为解密处理后的第三接收数据包,因此针对所述第四输出结果不再执行解密处理。比如,所述NC协议位于完整性验证协议之后、且位于头压缩之前,则NC协议收到的第四接收数据包为解密、完整性验证处理后的第三接收数据包,因此针对所述第四输出结果不再执行解密以及完整性验证处理。
方式2、所述第二协议实体为第四RLC实体。
具体的,可以包含一个或多个RLC实体,其中不同的RLC实体可以对应不同的目标粒度下的不同对象;在接收到所述NC配置信息之后,可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的RLC实体中增加NC协议,而其他RLC实体中不增加NC协议。本方式中的第四RLC实体与前述情况一种的第三RLC实体可以相同也可以不同。
应理解,若存在执行NC的多个PDCP实体都可以执行NC,则所述执行NC的多个RLC实体中不同RLC实体的处理可以为相同的,只是这里不做重复说明。
上述第四RLC实体还可以替换称为第四RLC层(layer)或者第四RLC entity。
基于前述说明,所述第四RLC实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第四RLC实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实 体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第二NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
所述RLC可以存在UM(非确认,Un-Acknowledged mode)、AM(确认,Acknowledged mode)以及TM(transport mode,透传模式)三种传输模式,比如,所述NC协议的功能应用于RLC非确认UM模式传输的所述第四接收数据包和/或RLC确认模式AM传输的所述第四接收数据包。其中,所述NC协议针对RLC的哪种模式传输的第四接收数据包进行处理,可以是预定义的。
所述第四RLC实体为双向(bi-directional)RLC实体或单向(unidirectional)RLC实体。也就是说,所述NC协议针对哪种类型的RLC实体中传输的待传输数据包进行处理,可以是预定义的。应理解上述仅为示例性说明,实际可以针对全部RLC实体类型均进行处理,只是不做穷举。
在所述第二协议实体为所述第四RLC实体的情况下,所述第三数据包为RLC协议数据单元PDU。
所述NC协议的功能应用于所述RLC PDU的数据部分,或RLC SDU,或RLC SDU的数据部分。也就是说,所述第四接收数据包具体为RLC PDU的数据部分,或者,RLC SDU,或者,RLC SDU的数据部分。
其中,所述RLC PDU可以是在所述RLC SDU的基础上封装得到的。
其中,所述第三接收数据包中还携带所述第三接收数据包的序列号(SN,Sequence Number)。也就是说,在所述RLC PDU中还可以携带SN号。
本处理方式中,所述NC协议在所述第四RLC实体中的位置也可以是根据实际情况进行设置的,下面分以下几种位置来进行说明:
所述NC协议位于所述第四RLC实体中的第七协议之前或之后;
所述第七协议包括以下之一:去RLC包头协议,SDU重组协议。
结合图8-图9进行示例性说明,图8-图9中接收UM-RLC实体(entity)即前述第四RLC实体;NC即NC协议,去RLC包头即前述去RLC包头协议,SDU重组即前述SDU重组协议。参见图8,NC协议位于SDU重组之后。参见图9,所述NC协议位于去RLC包头之后,以及SDU重组之前。
结合图10进行示例性说明,图10中对应了RLC为AM传输模式,其中右侧为第四RLC实体,NC即NC协议,NC协议位于SDU重组之后。
所述第四RLC实体中对所述NC协议得到的所述第四输出结果不执行的处理包括以下至少之一:SDU重组、去RLC包头。其中,所述第四RLC实体中对所述NC协议处理得到的所述第四输出结果不执行的处理,与所述NC协议在所述第四RLC实体中的位置相关。
也就是说,所述NC协议在所述第四RLC实体中所处的位置,会对所述NC协议的第二输出结果所执行的处理有影响,比如,所述NC协议位于去RLC包头之后,则NC协议收到的第四接收数据包为去RLC包头处理后的第三接收数据包,因此针对所述第四输出结果不再执行去RLC包头处理。比如,所述NC协议位于去RLC包头、重组之后,则NC协议收到的第四接收数据包为去RLC包头、重组处理后的第三接收数据包,因此针对所述第速输出结果不再执行去RLC包头、重组处理,并且该第四输出结果直接输入到下一级实体中。
方式3、所述第二协议实体为第四SDAP实体。
具体的,可以包含一个或多个SDAP实体,其中不同的SDAP实体可以对应不同的目标粒度下的不同对象;在接收到所述NC配置信息之后,可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的RLC实体中增加NC协议,而其他RLC实体中不增加NC协议。本方式中的第四SDAP实体与前述情况一种的第三SDAP实体可以相同也可以不同。
应理解,若存在执行NC的多个SDAP实体都可以执行NC,则所述执行NC的多个SDAP实体中不同SDAP实体的处理可以为相同的,只是这里不做重复说明。
上述第四SDAP实体还可以替换称为第四SDAP层(layer)或者第四SDAP entity。
基于前述说明,所述第四SDAP实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第四SDAP实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第二NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
在所述第二协议实体为所述第四SDAP实体的情况下,所述第三接收数据包为SDAP协议数据单元PDU。所述NC协议的功能应用于所述SDAP SDU的数据部分,或SDAP SDU,或SDAP PDU的数据部分。也就是说,所述第三接收数据包具体为SDAP SDU的数据部分,或SDAP SDU,或SDAP PDU的数据部分。
和/或,所述NC协议的功能应用于有SDAP包头的SDAP PDU。也就是说,第三接收数据包即所述SDAP PDU为有SDAP包头的SDAP PDU,若该原SDAP PDU中包含SDAP包头,则的第四SDAP实体中包含的NC协议可以对其进行NC处理;若该原SDAP PDU中不包含SDAP包头,则的第四SDAP实体中包含的NC协议可以不对其进行NC处理。
应理解,上述两种实施方式可以结合使用,比如,所述NC协议的功能应用于有SDAP包头的SDAP PDU的数据部分。
本处理方式中,所述NC协议在所述第四SDAP实体中的位置也可以是根据实际情况进行设置的,比如,所述NC协议位于所述第四SDAP实体中的映射服务质量数据流QoS flow到DRB的协议之后,或,移除SDAP包头的协议之后。比如,参见图11,NC协议即图11中的NC,发送SDAP实体即本实施例中的第四SDAP实体,该NC协议在图11示意出的位置为移除SDAP包头之后。
所述NC协议在所述第四SDAP实体中所处的位置,会对所述NC协议的第四输出结果所执行的处理相关,比如,所述NC协议位于映射服务质量数据流QoS flow到DRB的协议之后,则所述第四SDAP实体中针对所述第四输出结果不再执行映射服务质量数据流QoS flow到DRB的处理。比如,所述NC协议位于映射服务质量数据流QoS flow到DRB的协议之后,则NC协议收到的第四接收数据包为映射服务质量数据流QoS flow到DRB处理后的第三接收数据包,所述第四SDAP实体中针对所述第四输出结果不再执行映射服务质量数据流QoS flow到DRB的处理。比如,所述NC协议位于移除DSAP包头之后,则NC协议收到的第四接收数据包为映射服务质量数据流QoS flow到DRB、移除DSAP包头处理后的第三接收数据包,因此所述第四SDAP实体中针对所述第四输出结果不再执行映射服务质量数据流QoS flow到DRB、移除DSAP包头的处理;并且该第四输出结果可以直接输入到该第四SDAP实体的下一个实体。
方式4、所述第二协议实体为第四MAC实体。
具体的,可以包含一个或多个MAC实体,其中不同的MAC实体可以对应不同的目标粒度下的不同对象;在接收到所述NC配置信息之后,可以根据所述NC配置信息为针对目标粒度下的一个或多个对象的配置,来确定将该目标粒度下的一个或多个对象所对应的MAC实体中增加NC协议,而其他MAC实体中不增加NC协议。本方式中的第四MAC实体与前述情况一种的第三MAC实体可以相同也可以不同。
应理解,若存在执行NC的多个MAC实体都可以执行NC,则所述执行NC的多个MAC实体中不同MAC实体的处理可以为相同的,只是这里不做重复说明。
上述第四MAC实体还可以替换称为第四MAC层(layer)或者第四MAC entity。
基于前述说明,所述第四MAC实体中可以包括一个第一NC实体,所述第一NC实体用于对接收到的数据包进行处理以及对待传输数据包进行处理;上述第一NC实体还可以替换性的称为第一NC instance。或者所述第四MAC实体中可以包括一个第二NC实体和一个第三NC实体;所述第二NC实体用于对接收到的数据包进行处理;所述第三NC实体用于对待传输数据包进行处理。上述第二NC实体还可以替换性的称为第二NC instance;上述第三NC实体还可以替换性的称为第三NC instance。
在本处理方式中下述若无特殊说明,NC协议可以替换性描述为第一NC实体,或者NC协议可以替换性描述为第二NC实体。只是为了描述方便下文统一采用NC协议的描述方式而不作为限定。
在所述第二协议实体为所述第四MAC实体的情况下,所述第三接收数据包为MAC PDU。
在一种实施方式中,所述NC协议的功能应用于所述MAC SDU的数据部分,或MAC SDU,或MAC PDU的数据部分。也就是说,在所述第四MAC实体中NC协议用于对所述SDAP PDU的数据部分进行处理,或者,在所述第四MAC实体中的NC协议用于对MAC SDU进行处理,或者,在所述第四MAC实体中的NC协议用于对MAC SDU的数据部分进行处理。
本处理方式中,所述NC协议在所述第四MAC实体中的位置也可以是根据实际情况进行设置的,比如,所述NC协议位于所述第四MAC实体中的以下子层之一的之前或之后:逻辑信道优先级协议、解复用协议,HARQ进程协议。比如,参见图12,图12中右侧为上述第四MAC实体,NC协议即图12中的NC,该NC协议在图12示意出的位置为HARQ进程(即HARQ进程协议)之后,复用(即复用协议)之前。
所述第四MAC实体中对所述NC协议得到的所述第三输出结果不执行的处理包括映射服务质量数据流QoS flow到DRB。其中,所述第四MAC实体中对所述NC协议处理得到的所述第三输出结果不 执行的处理,与所述NC协议在所述第四MAC实体中的位置相关。比如,所述NC协议位于复用协议之后,则所述第二SDAP实体中针对所述第三输出结果不再执行复用的处理。比如,所述NC协议位于解复用协议之后,则NC协议收到的第四接收数据包为HARQ、复用处理后的第三接收数据包,因此所述第四MAC实体中针对所述第四输出结果不再执行HARQ和解复用的处理。比如,所述NC协议位于HARQ之前,则NC协议收到的第四接收数据包为从上一个实体直接传输来的第三接收数据包,因此所述第四MAC实体中针对所述第二输出结果需要执行逻辑信道优先级、解复用以及HARQ处理。比如,所述NC协议位于逻辑信道优先级之后,则NC协议收到的第二接收数据包为逻辑信道优先级、解复用以及HARQ处理后的第一接收数据包,因此所述第四MAC实体中针对所述第二输出结果不再执行逻辑信道优先级、解复用以及HARQ处理;且该第二输出结果直接输入到第四MAC实体的下一个实体。
可见,通过采用上述方案,就可以在第二协议实体中添加网络编码协议,如此可以使得在通信网络的协议层的任意一个协议实体中支持网络编码功能,从而通过在协议实体中增加网络编码功能,可以在利用更少的传输资源的情况下,提升数据传输的可靠性,保证整体的处理效率。
以下对本公开前述第一方面实施例和/或第二方面实施例进行示例性说明:
