Description

一种通信方法及相关产品
本申请要求于2021年10月09日提交中国专利局、申请号为202111176882.3、申请名称为“一种通信方法及相关产品”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
本申请涉及电子技术领域,具体涉及一种通信方法及相关产品。
背景技术
随着科技的发展和社会的进步,为了提供更高的业务速率,第三代合作伙伴计划3GPP(3 rdGenerationPartnershipProject)引入载波聚合(CarrierAggregation,简称CA)功能,将多个连续或非连续的分量载波(ComponentCarrier,简称CC)聚合成更大的带宽,以及双连接(DualConnectivity)功能,充分利用不同载波、不同制式的资源和优势,提升用户的上下行峰值速率体验。
而在现有的网络架构中,在CA场景下,控制面和用户面都承载在主载波小区PCC上,然后再通过PCC的RLC层将用户面的数据分流到辅载波小区SCC上发送。同样地,在CA场景下,上行和下行也是都承载在同一个载波小区上(PCC或SCC)。同时在双连接DC(DualConnectivity)场景下,上行和下行也是都承载在同一个载波小组上(主载波小组MCG或辅载波小组SCG)。
而在这样多载波的场景下(CA或DC),控制面和用户面、上行和下行的强耦合(承载在同一个载波上),会导致在载波能力差异大时,比如SCC的载波能力远大于PCC的载波能力时,这时SCC可以承载大部分流量,所以承载在PCC的用户面的流量需要经过PCC的RLC层分流到SCC上,分流的过程不仅增加了额外的路径造成路径时延,而且该路径也会限制分流过来的流量,从而无法根据业务诉求最大化地利用资源。
发明内容
本申请提供了一种通信方法及相关产品,以降低通信资源的浪费,提升通信资源的利用率。
第一方面,本申请实施例提供了一种通信方法,其特征在于,应用于网络设备,所述方法包括:通过主载波小区PCC进行第一类型数据的传输,以及通过辅载波小区SCC进行第二类型数据的传输;其中,所述第一类型数据包括控制面数据、所述第二类型数据包括用户面数据,或者所述第一类型数据包括上行数据、所述第二类型数据包括下行数据,或者所述第一类型数据包括下行数据、所述第二类型数据包括上行数据。
本申请实施例,应用于载波聚合CA场景,采用用户面和控制面、上行和下行分离的架构,将原本的控制面和用户面、上行和下行只可承载在同一载波上,变成控制面在PCC上、用户面在SCC上,或者上行在PCC上、下行在SCC上,或者下行在PCC上、上行在SCC上。区别于现有技术中的架构,控制面和用户面、或者上行和下行只可承载在同一载波上,而本申请实施例不仅可以将用户面和控制面分别承载在不同的载波上,例如控制面在PCC上, 用户面在SCC上,这样当SCC的载波能力大于PCC的载波能力时,超过PCC能力之外的数据需要由PCC的RLC层发送、经过传输通道、再通过SCC的MAC层发送给终端,引入了额外的路径时延;此外,若传输通道受限,SCC的能力也无法得到充分利用,浪费了资源;而且可以将上下行分离部署,这样上下行可以分别选择性能最优的载波部署。例如业务量大的下行需要部署在大带宽的SCC上,但是SCC的上行能力较弱,但PCC的上行能力较强,下行能力较弱,这时候如果还是采用上下行部署的强耦合就会导致总有一方的性能受损。所以利用本申请实施例提供的分离架构,上下行可以分别选择性能更优的载波部署。综上,通过本申请实施例所提供的通信方法,可以将用户面和控制面、或者上行和下行分别部署在不同的载波上,从而可以充分利用不同载波的资源和优势,使资源得到最大化地利用,提高业务速率。
在一种可能的实现方式中,所述第一类型数据包括控制面数据、所述第二类型数据包括用户面数据;所述通过主载波小区PCC进行第一类型数据的传输,包括:通过PCC的分组数据汇聚协议PDCP层生成第一消息,并发送给所述PCC的无线链路控制RLC层;通过所述PCC的所述RLC层接收所述第一消息,利用所述第一消息生成第二消息,并发送给所述PCC的媒体接入控制MAC层。

在一种可能的实现方式中,所述第一类型数据包括上行数据、所述第二类型数据包括下行数据;所述通过主载波小区PCC进行第一类型数据的传输,包括:通过PCC的MAC层生成第一消息或者通过所述PCC的所述MAC层生成一部分所述第一消息,再通过所述SCC的 MAC层生成另一部分所述第一消息,并发送给所述PCC的RLC层;通过所述PCC的所述RLC层接收所述第一消息,利用所述第一消息生成第二消息,并发送给所述PCC的PDCP层。本申请实施例,通过将上行数据部署在PCC上,下行数据部署在SCC上的分离架构提高上下行峰值速率。通过PCC的MAC层生成第一消息或者通过所述PCC的所述MAC层生成一部分所述第一消息,再通过所述SCC的MAC层生成另一部分所述第一消息,并发送给所述PCC的RLC层;通过所述PCC的所述RLC层接收所述第一消息,利用所述第一消息生成第二消息,并发送给所述PCC的PDCP层。这种分离的架构可以使得,下行的数据从核心网直接到达SCC,由SCC空口直接发送,避免了路径迂回,减少了数据传输时延;同时,即使超出SCC能力的数据需要发往PCC,PCC能力较小,所需的传输带宽也小,这样便减少了传输受限的场景。

具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例进行描述。
本申请的说明书和权利要求书及所述附图中的术语“第一”、“第二”、“第三”和“第四”等是用于区别不同对象,而不是用于描述特定顺序。此外,术语“包括”和“具有”以及它们任何变形,意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元,而是可选地还包括没有列出的步骤或单元,或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着,结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例,也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是,本文所描述的实施例可以与其它实施例相结合。
在本说明书中使用的术语“部件”、“模块”、“系统”等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如,部件可以是但不限于,在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。通过图示,在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程和/或执行线程中,部件可位于一个计算机上和/或分布在2个或更多个计算机之间。此外,这些部件可从在上面存储有各种数据结构的各种计算机可读介质执行。部件可例如根据具有一个或多个数据分组(例如来自与本地系统、分布式系统和/或网络间的另一部件交互的二个部件的数据,例如通过信号与其它系统交互的互联网)的信号通过本地和/或远程进程来通信。
首先,分析并提出本申请所具体要解决的技术问题。随着科技的发展和社会的进步,为了提供更高的业务速率,3GPP引入CA功能,将多个连续或非连续的分量载波聚合成更大的带宽,以及DC功能,充分利用不同载波、不同制式的资源和优势,提升用户的上下行峰值速率体验。而在现有的网络架构中,在CA场景下,控制面和用户面都承载在主载波小区PCC上,然后再通过PCC的RLC层将用户面的数据分流到辅载波小区SCC上发送。同样地,在CA场景下,上行和下行也是都承载在同一个载波小区上(PCC或SCC)。同时在DC场景下,上行和下行也是都承载在同一个载波小组上(主载波小组MCG或辅载波小组SCG)。
而在这样多载波的场景下(CA或DC),控制面和用户面、上行和下行的强耦合(承载在同一个载波上),会导致在载波能力差异大时,比如SCC的载波能力远大于PCC的载波能力时,这时SCC可以承载大部分流量,所以承载在PCC的用户面的流量需要经过PCC的RLC层分流到SCC上,分流的过程不仅增加了额外的路径造成路径时延,而且该路径也会限制分流过来的流量,从而无法根据业务诉求最大化地利用资源。
综上所述,现有的通信方法无法满足用户对上下行峰值速率的需求,并且造成了大量资源的浪费。因此,在本申请提供的通信方法用于解决上述技术问题。
为了便于理解本申请实施例,以下示例性列举本申请中通信方法所应用的场景,可以包括如下两个场景:
场景一,应用于载波聚合CA场景:
载波聚合CA是在3GPP在Release10阶段引入,通过将多个连续或非连续的载波(ComponentCarrier,简称CC)聚合成更大的带宽,以满足3GPP的要求。详细请参见图1,图1是本申请实施例提供的一种载波聚合的系统架构示意图,如图1所示,该系统架构可以包括终端设备100、网络设备110、多个不同的载波F1、F2、F3等、NR。新空口NR(New Radio)是表示终端设备与网络设备建立无线连接的通道。F1、F2、F3等代表的是不同的载波。终端设备100与网络设备110通过NR中的多个连续或非连续的载波(F1、F2、F3等)聚合成更大的带宽进行数据的传输就叫做载波聚合的过程。
场景二,应用于双连接DC场景:
双连接的场景表示,一个终端设备与两个网络设备保持连接。详见图2,图2为本申请实施例提供的一种双连接的系统架构示意图,如图2所示,该系统架构可以包括终端设备200、网络设备210、网络设备220。终端设备200分别与网络设备210和网络设备220建立连接。
可以理解的是,上述两种应用场景的只是本申请实施例中的几种示例性的实施方式,本申请实施例中的应用场景包括但不仅限于以上应用场景。
基于上述提出的技术问题以及本申请中对应的应用场景,也为了便于理解本申请实施例,下面先对本申请实施例所基于的其中一种网络架构进行描述。请参阅图3,图3本申请实施例提供的一种通信方法的架构图。本申请实施例的技术方法可以在图3举例所示的系统架构或类似的系统架构中具体实施。如图3所示,该系统架构可以包括核心网设备和网络设备,如图3所示,该方法可应用于上述图1中所述的系统架构中,其中的图1中的架构可以用于支持并执行图3中所示的方法流程步骤S301。下面将结合附图3从网络设备侧进行描述。该方法可以包括以下步骤S301。
步骤S301:通过主载波小区PCC进行第一类型数据的传输,以及通过辅载波小区SCC 进行第二类型数据的传输。
具体地,所述第一类型数据包括控制面数据、所述第二类型数据包括用户面数据,或者所述第一类型数据包括上行数据、所述第二类型数据包括下行数据,或者所述第一类型数据包括下行数据、所述第二类型数据包括上行数据。
例如,所述第一类型数据包括控制面的数据、所述第二类型数据包括用户面数据的具体过程可以包括如下步骤:
请参阅图4,图4本申请实施例提供的一种用户面和控制面分离的流程示意图。首先通过PCC的PDCP层401接收到核心网的控制面传来的数据,然后经过PCC的PDCP层生成第一消息,然后将生成的所述第一消息发送给PCC的RLC层402。所述PCC的RLC层接收到所述第一消息后,利用所述第一消息生成第二消息,并将所述第二消息发送给PCC的MAC层403。最终由MAC层将所述第三消息发送给终端设备。同时,通过SCC的PDCP层404生成第三消息,并发送给所述SCC的RLC层405。然后通过所述SCC的所述RLC层接收所述第三消息,利用所述第三消息生成第四消息,并发送给所述SCC的MAC层406。或者通过所述SCC的所述RLC层接收所述第三消息,并利用所述第三消息生成第四消息,将所述第四消息的一部分发送给所述SCC的MAC层406,将所述第四消息的另一部分发送给所述PCC的MAC层403。可选的,上述步骤也可应用于图3a,图3a是本申请实施例提供的一种通信方法的流程示意图。上述流程也适用于该系统架构。
采用上述传输路径的技术效果可以参见图5a和图5b,图5a是本申请实施例提供的一种用户面和控制面都在PCC上部署的架构图,图5a是现有的架构,来自核心网503的控制面CP和用户面UP都部署在PCC501上,这样用户面只能通过PCC的RLC层将数据分流到SCC502上发送到终端设备500上。这样就导致了当SCC可承载大部分流量的时候,但是数据还要经过PCC分流就会引入路径时延,而且容易受传输管道限制,从而导致CA的增益损失。但是当采用本申请实施例提供的架构就可以得到如图5b的部署。图5b是本申请实施例提供的一种控制面在PCC,用户面在SCC上部署的架构图。图5b中来自核心网503的控制面CP部署在PCC501上,用户面UP部署在SCC502上。
而采用传统的CA架构如图5a,控制面和用户面承载只能部署在PCC上,数据由PCC的RLC分流到SCCMAC。若SCC载波能力大于PCC载波能力,超过PCC能力之外的数据需要由PCCRLC发送、经过传输通道、再通过SCCMAC发送给终端,引入了额外的路径时延;此外,若传输通道受限,SCC的能力也无法得到充分利用,影响用户体验。采用本申请中的分离架构如图5b之后,用户面可承载在SCC上,数据从核心网直接到达SCC,由SCC空口直接发送,避免了路径迂回,减少了数据传输时延;同时,即使超出SCC能力的数据需要发往PCC,PCC能力较小,所需的传输带宽也小,减少了传输受限的场景;
当所述第一类型数据包上行的数据、所述第二类型数据包括下行的数据的具体过程可以包括如下步骤:
请参见图6,图6是本申请实施例提供的一种上行在PCC,下行在SCC上部署的架构图。首先通过PCC的MAC层601生成第一消息或者通过所述PCC的所述MAC层601生成一部分所述第一消息,再通过所述SCC的MAC层606生成另一部分所述第一消息,并发送给所述PCC的RLC层602;通过所述PCC的所述RLC层接收所述第一消息,利用所述第一消息生成第二消息,并发送给所述PCC的PDCP层603。可选的然后,首先通过SCC的PDCP层 604生成第三消息,并发送给所述SCC的RLC层605;通过所述SCC的所述RLC层接收所述第三消息,利用所述第三消息生成第四消息,并发送给所述SCC的MAC层606;或者通过所述SCC的所述RLC层605接收所述第三消息,并利用所述第三消息生成第四消息,将所述第四消息的一部分发送给所述SCC的MAC层601,将所述第四消息的另一部分发送给所述PCC的MAC层606。
当所述第一类型数据包下行的数据、所述第二类型数据包括上行的数据的具体过程可以包括如下步骤:
请参见图7,图7是本申请实施例提供的一种下行在PCC,上行在SCC上部署的架构图。首先是通过PCC的PDCP层701生成第一消息,并发送给所述PCC的RLC层702;通过所述PCC的所述RLC层接收所述第一消息,利用所述第一消息生成第二消息,并发送给所述PCC的MAC层703。或者通过所述PCC的所述RLC层702接收所述第一消息,并利用所述第一消息生成第二消息,将所述第二消息的一部分发送给所述PCC的MAC层703,将所述第二消息的另一部分发送给所述SCC的MAC层704。可选的然后通过SCC的MAC层704生成第三消息或者通过所述SCC的所述MAC层生成一部分所述第三消息,再通过所述PCC的MAC层703生成另一部分所述第三消息,并发送给所述SCC的RLC层705;通过所述SCC的所述RLC层接收所述第三消息,利用所述第三消息生成第四消息,并发送给所述SCC的PDCP层706。
采用上述传输路径的技术效果可以参见图8a-图8d,图8a是本申请实施例提供的一种下行上行都在PCC/MCG上承载的架构图,图8a是现有的架构,终端设备800的上行和下行任务都部署在PCC/MCG801上。图8b是本申请实施例提供的一种下行上行都在SCC/SCG上承载的架构图。图8b是现有的架构,终端设备800的上行和下行任务都部署在SCC/SCG802上。图8c是本申请实施例提供的一种上行在PCC/MCG,下行在SCC/SCG上承载的架构图。图8c是本申请实施例提供的架构,终端设备800的上行部署在PCC/MCG801,下行部署在SCC/SCG802上。图8d是本申请实施例提供的一种下行在PCC/MCG,上行在SCC/SCG上承载的架构图。图8d是本申请实施例提供的架构,终端设备800的下行部署在PCC/MCG801,上行部署在SCC/SCG802上。
而上图可以看出传统的CA/DC架构,上下行只能统一部署在一个载波上,当载波的上下行能力不相当,且上下行业务诉求不一致时,会导致上下行部署冲突,无法同时获得性能最优。比如在FDD和TDD组合场景,业务量大的下行需要部署在大带宽的TDD上,但TDD上行能力较弱,上行业务需要部署在FDD上,上下行部署的强耦合会导致总有一方性能受损。本申请采用上下行分离部署,上下行可分别选择性能最优的载波部署。
综上,将上述步骤应用于载波聚合CA场景,采用用户面和控制面、上行和下行分离的架构,将原本的控制面和用户面、上行和下行只可承载在同一载波上,变成控制面在PCC上、用户面在SCC上,或者上行在PCC上、下行在SCC上,或者下行在PCC上、上行在SCC上。区别于现有技术中的架构,控制面和用户面、或者上行和下行只可承载在同一载波上,而本申请实施例不仅可以将用户面和控制面分别承载在不同的载波上,例如控制面在PCC上,用户面在SCC上,这样当SCC的载波能力大于PCC的载波能力时,超过PCC能力之外的数据需要由PCC的RLC层发送、经过传输通道、再通过SCC的MAC层发送给终端,引入了额外的路径时延;此外,若传输通道受限,SCC的能力也无法得到充分利用,浪费了资源;而且可以将上下行分离部署,这样上下行可以分别选择性能最优的载波部署。例如业务量大 的下行需要部署在大带宽的SCC上,但是SCC的上行能力较弱,但PCC的上行能力较强,下行能力较弱,这时候如果还是采用上下行部署的强耦合就会导致总有一方的性能受损。所以利用本申请实施例提供的分离架构,上下行可以分别选择性能更优的载波部署。综上,通过本申请实施例所提供的通信方法,可以将用户面和控制面、或者上行和下行分别部署在不同的载波上,从而可以充分利用不同载波的资源和优势,使资源得到最大化地利用,提高业务速率。

可选的,网络设备在发送上述消息的同时,还通过在SCG的PDCP层904生成第七消息,并发送给SCG的RLC层905;所述SCG的RLC层接收所述第七消息,利用所述第七消息生成第八消息,并发送给SCG的MAC层906;或者网络设备通过在SCG的PDCP层904生成第七消息,将所述第七消息的一部分发送给所述SCG的RLC层905,将所述第七消息的另一部分发送给所述MCG的RLC层902;所述SCG的RLC层接收所述第七消息的一部分,利用所述第七消息的一部分生成第八消息,并发送给SCG的MAC层906;所述MCG的RLC层接收第七消息的另一部分,利用所述第七消息的另一部分生成第九消息,并发送给MCG的MAC层901。
例如,所述第三类型数据包括下行数据、所述第四类型数据包括上行数据的具体过程可以包括如下步骤:
参见图9b,图9b是本申请实施例提供的一种下行在MCG,上行在SCG上部署的架构图。首先通过在MCG的PDCP层903生成第五消息,并发送给MCG的RLC层902;所述MCG的RLC层接收所述第五消息,利用所述第五消息生成第六消息,并发送给MCG的MAC 层901;或者通过在MCG的PDCP层903生成第五消息,将所述第五消息的一部分发送给所述MCG的RLC层902,将所述第五消息的另一部分发送给所述SCG的RLC层905;所述MCG的RLC层接收所述第五消息的一部分,利用所述第五消息的一部分生成第六消息,并发送给MCG的MAC层901;所述SCG的RLC层接收第五消息的另一部分,利用所述第五消息的另一部分生成第六消息,并发送给SCG的MAC层906。
可选的然后,通过在SCG的MAC层906生成第七消息,并发送给SCG的RLC层905;所述SCG的RLC层接收所述第七消息,利用所述第七消息生成第八消息,并发送给SCG的PDCP层904。或者,通过SCG的MAC层906生成一部分第七消息和MCG的MAC层901生成另一部分第七消息,并将所述一部分第七消息发送给SCG的RLC层905,所述另一部分第七消息发送给MCG的RLC层902;所述SCG的RLC层接收所述一部分第七消息,利用所述一部分第七消息生成第八消息,并发送给SCG的PDCP层904;所述MCG的RLC层接收另一部分第七消息,利用所述另一部分第七消息生成第八消息,并发送给SCG的PDCP层904。可选的,上述流程步骤也可用于图9c的系统架构,图9c是本申请实施例提供的又一种通信方法的流程示意图。
而上图可以看出传统的CA/DC架构,上下行只能统一部署在一个载波上,当载波的上下行能力不相当,且上下行业务诉求不一致时,会导致上下行部署冲突,无法同时获得性能最优。比如在FDD和TDD组合场景,业务量大的下行需要部署在大带宽的TDD上,但TDD上行能力较弱,上行业务需要部署在FDD上,上下行部署的强耦合会导致总有一方性能受损。本申请采用上下行分离部署,上下行可分别选择性能最优的载波部署。
综上,将本申请实施例应用于双连接DC场景,采用上行和下行分离的架构,将原本的上行和下行只可承载在同一载波上,变成上行在MCG上,下行在SCG上,或下行在SCG上,上行在MCG上。区别于现有技术中的架构,上行和下行只可承载在同一载波上,而本申请实施例可以将上下行分离部署,这样上下行可以分别选择性能最优的载波部署。例如业务量大的下行需要部署在大带宽的SCG上,但是SCG的上行能力较弱,但MCG的上行能力较强,下行能力较弱,这时候如果还是采用上下行部署的强耦合就会导致总有一方的性能受损。所以就需要本申请实施例提供的分离架构,上下行可以分别选择性能最优的载波部署。综上,为了提更高的业务速率,可以通过本申请实施例所提供的通信方法,可以将上行和下行分别部署在不同的载波上,从而可以充分利用不同载波的资源和优势,使资源得到最大化地利用。
