Description

一种确定复制传输资源的方法、终端设备和网络设备 技术领域
本发明涉及通信技术领域,尤其涉及一种确定复制传输资源的方法、终端设备和网络设备。
背景技术
目前,为了保证数据传输的可靠性,降低数据传输的时延,对于可以采用数据复制传输的方式传输数据,复制传输通常是通过多个传输路径在发送端与接收端之间进行传输的,也就是说,发送端(如终端设备)可以通过多个无线链路控制(radio link control,RLC)实体,将复制的多份数据传输至媒体访问控制(media access control,MAC)实体,并由这些MAC实体通过空口将数据传输至接收端(如,网络设备)。
在新无线非授权(new radio unlicensed,NR-U)频谱中,进行数据传输之前需要通过LBT机制,先侦听载波是否空闲,在侦听到载波空闲的情况下,才可以通过该载波传输数据,若侦听到载波被占用,则需要等待一段时间继续侦听,直到侦听到载波空闲才可以发送数据。
上述NR-U频谱中,即使采用复制传输的方式传输数据,在传输数据之前,也需要对载波进行侦听,在载波被占用的情况下可能需要等待一段时间,或者仅有部分复制传输路径可用于传输数据,甚至在载波的信号质量较差的情况下可能导致数据无法传输至接收端,因此仍然会存在数据传输的时延较大,数据传输的可靠性较低的问题。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
在本发明实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本发明实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
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。本文中符号“/”表示关联对象是或者的关系,例如A/B表示A或者B。
在本发明的描述中,除非另有说明,“多个”的含义是指两个或两个以上。例如,多个传输路径是指两个或两个以上的传输路径。
本发明提供的技术方案可以应用于各种通信系统,例如,5G通信系统,未来演进系统或者多种通信融合系统等等。可以包括多种应用场景,例如,机器对机器(machine to machine,M2M)、D2M、宏微通信、增强型移动互联网(enhance mobile broadband,eMBB)、超高可靠性与超低时延通信(ultra reliable&low latency communication,uRLLC)以及海量物联网通信(massive machine type communication,mMTC)等场景。例如:本发明实施例可以应用于与5G通信系统的NR-U中网络设备与终端设备之间的通信。
5G通信系统的工业互联网(industrial interest of Things,IIoT)场景中支持工业自动化(factory automation),传输自动化(transport industry),智能电力(electrical power distribution)等业务在5G通信系统的传输。为了保证这些业务的可靠性,在IIoT场景中支持增强的数据复制传输和多连接。
增强的复制传输方式,以R15的双链接(dual connectivity,DC)复制传输和载波聚合(carrier aggregation,CA)复制传输为基础,考虑了多于2个腿(legs)的复制传输场景。其中,数据复制传输时一个分组数据汇聚协议(packet data cnvergence protocol,PDCP)实体的数据包可以由对应的多个RLC实体或逻辑信道进行传输,一个对应的RLC实体或逻辑信道即可称为一个leg。也就是说,对一个PDCP实体,可以配置多个leg(即RLC实体或者逻辑信道)对多份复制好的数据进行复制传输,其中,每个leg可以承载一份数据。例如,对于配置了4个legs的,相应的可以支持最多4份数据的 复制传输。
相应的,R16中,基于DC场景和CA场景的复制传输中,一个PDCP实体对应最多4个RLC实体;基于CA场景,一个PDCP实体对应最多4个RLC实体。
上述在IIoT场景中,传输数据时采用的复制传输方案目前还未引入至NR-U场景中。
在Rel-17中超可靠和低时延通信(ultra reliability and low iatency communication,URLLC)场景中,将考虑如何将IIOT场景中的复制传输的方案使用在NR-U场景下,以提高数据传输的可靠性,以及降低数据传输的时延。
3GPP RAN工作组在2018年12月份同意了新无线(new radio,NR)非授权频谱工作方式的立项(项目的标号为:WID RP-182878),该项目的目标是使得NR工作在非授权频谱,其中,包括如下几种工作场景:
场景A:载波聚合场景,主小区(primary cell,PCell)工作在授权频段,通过载波聚合方式聚合工作在非授权频谱上的辅小区(secondary cell,SCell);
场景B:双连接工作场景,PCell工作在长期演进(long-term evolution,LTE)系统中的授权频段,主辅小区(primary secondary cell,PSCell)工作在NR非授权频谱;
场景C:独立工作场景,NR作为一个独立小区工作在非授权频谱;
场景D:NR单小区场景,上行工作在授权频段,下行工作在非授权频谱;
场景E:双连接工作场景,PCell为NR授权频段,PScell为NR非授权频谱。
一般来说,NR-U的工作频带(band)为5GHz非授权频谱和6GHz非授权频谱。在非授权频谱上,NR-U的设计应该保证与其他已经工作在这些非授权频谱上的系统(比如WiFi)之间的公平性等。公平性的原则是,NR-U对于已经部署在非授权频谱上的系统的影响不能超过这些系统之间的影响。
为了保证在非授权频谱上各系统之间的公平性共存,能量检测已经被同意作为一个基本的共存机制。一般的能量检测机制为LBT机制,该机制的基本原理为:基站或者终端(发送端)在非授权频谱上传输数据之前,需要先按照规定侦听一段时间。如果侦听的结果表示载波(或信道)为空闲状态,则发送端可以通过该载波给接收端传输数据。如果侦听的结果表示载波为占用状态,则发送端需要根据等待一段时间再继续侦听载波,知道载波侦听结果为空闲状态,才能向接收端传输数据。
在新无线非授权(new radio unlicensed,NR-U)频谱中,进行数据传输之前需要通过LBT机制,先侦听载波是否空闲,在侦听到载波空闲的情况下,才可以通过该载波传输数据,若侦听到载波被占用,则需要等待一段时间继续侦听,直到侦听到载波空闲才可以发送数据。
上述NR-U频谱中,即使采用复制传输的方式传输数据,在传输数据之前,也需要对载波进行侦听,在载波被占用的情况下可能需要等待一段时间,或者仅有部分复制传输路径可用于传输数据,甚至在载波的信号质量较差的情况下可能导致数据无法传输至接收端,因此仍然会存在数据传输的时延较大,数据传输的可靠性较低的问题。
为了解决上述问题,本发明实施例提供一种确定复制传输资源的方法、终端设备和网络设备,该方法在NR-U中,引入了复制传输的方式传输数据,并且可以通过LBT结果,灵活的确定复制传输资源,从而可以降低数据传输的时延,提高数据传输的可靠性。
本发明实施例提供的确定复制传输资源的方法,可以应用于无线通信系统。示例性的,如图1所示,为本发明实施例提供的一种无线通信系统的系统架构示意图。在图1中,该无线通信系统包括终端设备和网络设备。在实际应用中上述终端设备与网络设备之间的连接可以为无线连接。
在本发明实施例提供的确定复制传输资源的方法应用在图1所示的无线通信系统之中时,图1中的终端设备可以对非授权频谱中的载波进行LBT检测,得到LBT结果,然后终端设备可以根据LBT结果,选择进行复制传输的资源,或者,终端设备将LBT结果发送给图1中所示的网络设备,以使得网络设备通过接收到的LBT结果,为终端设备选择复制传输资源,并将选择的复制传输资源指示给终端设备,这样终端设备在非授权频谱中可以针对LBT成功的载波,确定一个或多个数据传输路径(即leg),如此在采用非授权频谱传输数据时,可以实现将复制后的多份数据通过多个传输路径进行传输。
本发明实施例中的终端设备可以称之为用户设备(user equipment,UE)。该终端设备可以为个人通信业务(personal communication service,PCS)电话、无绳电话、会话发起协议(session initiation protocol,SIP)话机、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)等设备,该终端设备也可以为手机、移动台(mobile station,MS)、移动终端(mobile terminal)和笔记本电脑等,该终端设备可以经无线接入网(radio access network,RAN)与一个或多个核心网进行通信。例如,终端设备可以是移动电话(或称为“蜂窝”电话)或具有移动终端的计算机等,例如,终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语音和/或数据。终端设备还可以为有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的网络中的终端设备等。上述仅仅是一种示例,实际应用中不限于此。
本发明实施例中的网络设备可以是LTE系统、NR通信系统或者授权辅助接入长期演进(authorized auxiliary access long-term evolution,LAA-LTE)系统中的演进型基站(evolutional node B,简称可以为eNB或e-NodeB)宏基站、微基站(也称为“小基站”)、微微基站、接入站点(access point,AP)、传输站点(transmission point,TP)或新一代基站(new generation Node B,gNodeB)等。上述网络设备还可以是未来5G通信系统或未来演进网络中的其他类网络设备。
本发明实施例提供的确定复制传输资源的方法,可以应用于确定上行(如,终端设备向网络设备传输数据)的复制传输资源,也可以应用于确定下行(如,网络设备向终端设备传输数据)的复制传输资源。
需要说明的是,本发明实施例提供的确定复制传输资源的方法,其可以应用在多种涉及确定复制传输资源的场景。示例性的可以包括以下几种:
场景1、已经为终端设备或网络设备确定或指示了复制传输资源,通过考虑LBT结果,更新复制传输资源(如,修改RLC实体)。例如,网络设备通过复制传输激活去激活MAC CE为终端设备指示了激活的复制传输资源。当然,在此之前,网络也可已经通过无线资源控制(radio resource control,RRC)重配置消息为终端设备配置了复制传输的初始模式。
场景2、未为终端设备或网络设备确定或指示复制传输资源,通过考虑LBT结果,确定或指示复制传输资源。例如,网络设备通过复制传输激活去激活MAC控制单元(MAC control element,MAC CE)为终端设备指示了激活的复制传输资源。
场景3、预先仅为终端设备或网络设备配置了复制传输的初始模式(其中可能包括激活的leg),通过考虑LBT结果,确定或指示复制传输资源(可以是修改初始模式中的复制传输资源,也可以是重新确定或指示复制传输资源)。例如,网络设备通过RRC重配置消息为终端设备配置了初始的复制传输资源。
应理解上述3种具体场景仅为示例性的说明,本发明实施例提供的确定复制传输资源的方法还可以应用在其他涉及确定复制传输资源的场景中。
首先针对应用于确定上行(如,终端设备向网络设备传输数据)的复制传输资源的方法进行介绍。
本发明实施例中提供的确定复制传输资源的方法,通过终端设备与网络设备之间的信息交互实现。可选的,该方法具体可以包括两种不同的实现方式:
第一种实现方式:由网络设备确定复制传输的资源;第二种实施方式:由终端设备确定复制传输的资源。
以下分别针对上述两种实施方式进行详细的说明。
第一种实施方式:由网络设备确定复制传输的资源
如图2所示,本发明实施例提供一种确定复制传输资源的方法,该方法包括:
101、网络设备确定复制传输的配置信息。
本发明实施例中,网络设备确定复制传输的配置信息可以包括:网络设备确定并配置对应的无线承载(resource bearer,RB),以及配置在采用数据复制传输时每个RB相关的至少一个复制传输路径(相当于leg,下文中均采用leg进行表述)。也就是说网络设备可以配置RB,以及RB与leg的对应关系, 其中,一个RB可以与至少一个leg对应。
示例性的,假设网络设备配置了3个RB,分别表示为RB1、RB2和RB3,那么可以为RB1配置leg1和leg2,为RB2配置leg3、leg4、leg5和leg6,为RB3配置leg7和leg8,其得到的配置信息具体可以如下表1所示的RB与leg的对应关系。

其中,表1中是以3组RB与leg的对应关系为例所作的示例性的说明,应理解本发明实施例中网路设备可以设置至少一组RB与leg的对应关系,其具体数量可以根据实际情况进行设置,本发明实施例不作限定。
网络设备确定并配置RB,以及配置RB所对应的leg可以有以下两种可选的实现方式:
一种可选的实现方式为:网络设备可以为所有的RB均配置对应的复制传输路径。
另一种可选的实现方式为:网络设备也可以针对部分RB配置复制传输路径。由于可能存在有一些RB是用来承载专用数据的,因此针对这种情况,可以针对除这些用来承载专用数据的RB之外的其他RB配置对应的复制传输路径。
其中,上述RB可以为数据无线承载(data resource bearer,DRB),上述RB还可以为信令无线承载(Signal resource bearer,SRB)。
其中,配置leg具体可以通过配置RLC实体或者逻辑信道来实现。
本发明实施例中,可配置的RLC实体或者逻辑信道的数量可以为至少一个。可选的,配置的RLC实体和逻辑信道的总数量可以不超过4个。
需要说明的是,本发明实施例中,配置的RCL实体和逻辑信道的具体数量不作限定,以实际进行数据复制传输时的需求进行确定,本发明实施例不作限定。
进一步的,网络设备确定复制传输的配置信息还可以包括:为每个leg配置对应的至少一个第二载波,即配置leg与第二载波的对应关系。
示例性的,结合上述表1,具体可以为leg1配置载波A,为leg2配置载波B和载波C,为leg3配置载波D和载波E,为leg4配置载波F,为leg5配置载波G,为leg6配置载波H,为leg7配置载波I,以及为leg8配置载波J,则可以得到如下表2所示的leg与第二载波的对应关系:
Leg 第二载波
leg1 载波A
leg2 载波B和载波C
leg3 载波D和载波E
leg4 载波F
leg5 载波G
leg6 载波H
leg7 载波I
leg8 载波J
表2
需要说明的是,上述表2仅为示例性的说明,具体的,网络设备确定复制传输的配置信息时配置的 第二载波的数量可以根据实际情况确定,本发明实施例不作限定。
102、网络设备向终端设备发送第四指示信息。
其中,第四指示信息用于指示上述101中所确定的复制传输的配置信息。
本发明实施例中,在上述101之后,网络设备可以先根据其确定的复制传输的配置信息,生成第四指示信息,然后可以将第四指示信息发送至网络设备。
其中,第四指示信息可以包括:至少一个RB的标识,以及每个RB的标识对应的至少一个复制传输路径的标识。
进一步的,第四指示信息中还可以包括:每个复制传输路径的标识对应的至少一个第二载波的标识。
可选的,网络设备可以通过专用信息将第四指示信息发送给终端设备。其中,该专用信息可以为RRC重配置消息、MAC CE等。例如,可以通过RRC重配置消息中的PDCP-config通知上述复制传输的配置信息。
103、终端设备配置复制传输路径,以及复制传输路径与RB的对应关系。
终端设备接收上述第四指示信息之后,可以根据第四指示信息中指示的复制传输的配置信息,配置复制传输路径,以及复制传输路径与RB的对应关系。
需要说明的是,上述101至103为可选的步骤,也就是说,本发明实施例提供的确定复制传输资源的方法也可以不执行上述101至103。
104、终端设备对非授权频谱中的目标载波进行LBT检测,得到目标载波的LBT结果。
可选的,上述非授权频谱可以为NR-U中的非授权频谱。
可选的,上述目标载波可以为以下任意一种载波。
第一种:目标载波为非授权频谱中的所有载波。
上述第一种情况可以存在两种可能:
一种可能为:目标载波为终端设备所支持的非授权频谱中的所有载波。
另一种可能为:目标载波为终端设备所支持的非授权频谱中,与上述复制传输的配置信息中配置的所有RB存在对应关系的载波。例如,根据上述表1和表2可知,与RB1对应的为载波A、载波B和载波C;与RB2对应的为载波D、载波E、载波F、载波G和载波H;与RB3对应的为载波I和载波J,因此,载波A、载波B、载波C、载波E、载波F、载波G和载波H为目标载波。
第二种:目标载波为至少一个第二载波中的载波。
也就是说,目标载波为所有第二载波中的至少一个载波。
第三种:目标载波为非授权频谱中处于激活状态的载波。
可选的,目标载波可以为终端设备所支持的非授权频谱中的所有载波中处于激活状态的载波。其中,处于激活状态的载波可以是指该载波对应的RB处于激活状态。
可选的,目标载波为终端设备所支持的非授权频谱中,与上述复制传输的配置信息中配置的所有RB存在对应关系的载波中处于激活状态的载波。
第四种:目标载波为至少一个第二载波中处于激活状态的载波。
可选的,除了上述四种以外,还可以包括以下第五种和第六种情况。由于leg和载波均与RB存在对应关系(如,上述表1和表2中所示),因此可以将某个复制传输的RB对应的至少一个第二载波中的载波作为上述目标载波。
第五种:目标载波为与某个复制传输的RB对应的至少第二载波中的载波。
第六种:目标载波为某个复制传输的RB对应的至少一个第二载波中处于激活状态的载波。
105、终端设备向网络设备发送LBT结果。
第一种可选的情况,上述LBT结果包括以下至少一种:LBT成功的指示、LBT失败的指示。
第二种可选的情况,上述LBT结果包括以下至少一种:信道占用时间(channel occupy time,COT)、载波标识、和部分带宽(band width part,BWP)标识。
需要说明的是,LBT结果在实际应用中可以将第一种可选的情况中所包括的全部参数或者部分参数 与第二种可选的情况中所包括的参数中的全部或者部分结合,具体可以将LBT成功的指示、LBT失败的指示、COT、载波标识、和BWP标识中的哪些参数进行结合,可以根据实际情况确定,本发明实施例中不再一一列举。
可选的,在LBT结果包括载波标识,以及LBT成功/失败的指示的情况下,载波标识可以为与LBT成功/失败的指示对应的载波标识。如:载波1LBT成功。
可选的,在LBT结果包括BWP标识,以及LBT成功/失败的指示的情况下,BWP标识可以为与LBT成功/失败的指示对应的BWP标识。如BWP1LBT成功。
可选的,在RB与载波存在对应关系的情况下,还可以通过RB标识来替换上述载波标识或BWP标识。
可选的,上述COT包括以下至少两种:
信道占用的起始时间、信道占用的终止时间和信道占用的持续时间。
也就是说,COT可以为以下(1)(2)和(3)三种情况:
(1)信道占用的起始时间和信道占用的终止时间。
(2)信道占用的起始时间和信道占用的持续时间。
(3)信道占用的终止时间和信道占用的持续时间。
106、网络设备根据LBT结果和复制传输的配置信息,确定复制传输资源。
其中,上述确定的复制传输资源可以包括以下至少一项:
至少一个复制传输路径、复制传输的数据份数(即copies),以及至少一个第一载波。其中,第一载波为目标载波中LBT结果为LBT成功的载波。
可选的,上述确定复制传输资源可以满足以下两个条件:
条件1:上述至少一个复制传输路径可以与上述至少一个第一载波对应,其中,每个复制传输路径对应至少一个第一载波。
条件2:上述至少一个复制传输路径可以为从上述101中配置的复制传输路径中选择的。
本发明实施例中,可以是根据LBT结果获知哪些载波LBT成功(即处于空闲状态),并从这些LBT成功的载波中选择用于复制传输的载波(记为载波1),进一步的,还可以结合复制传输的配置信息中RB、leg和载波之间的对应关系,确定与载波1对应的leg和RB;进一步的,还可以根据可以用来传输数据的leg的数量的限制,和对数据传输可靠性的要求来综合确定copies数,如此可以实现根据LBT结果和复制传输的配置信息,确定复制传输资源。
示例性的,假设配置信息如上述表1和表2所示,LBT结果显示载波A至载波J中侦听成功的载波为:载波A、载波B、载波C、载波D、载波E、载波F、载波G和载波H。那么在确定复制传输资源时,可以从载波A、载波B、载波C、载波D、载波E、载波F、载波G和载波H中选择载波,并选择对应的leg1、leg2和leg3这3条传输路径,然后可以进一步确定copies数小于或等于3。
需要说明的是,在本发明实施例提供的确定复制传输资源的方法中不执行上述101至103的情况下,上述106可以替换为下述106a。
106a、网络设备根据LBT结果,确定复制传输资源。
针对上述场景1或场景3的情况,网络设备可能已经为终端设备配置过复制传输资源,此时执行106a可以是结合终端设备上报的LBT结果,更新配置过的复制传输资源。
示例性的,假设之前为终端设备配置有复制传输资源:RLC实体1,RLC实体2,其中,RLC实体1对应载波A,RLC实体2对应载波B,若LBT结果为载波A和载波C处于空闲状态、载波B处于被占用的状态,那么此时网络设备可以根据LBT结果,确定复制传输资源为:RLC实体1,RLC实体3,其中,RLC实体1对应载波A,RLC实体3对应载波C。
示例性的,针对上述场景1或场景3的情况,网络设备可能已经为终端设备配置过复制传输资源,此时执行106a可以是结合终端设备上报的LBT结果,修改配置过的复制传输资源,例如在已经激活的leg中根据LBT结果,删除LBT结果不满足(如LBT失败)的leg,最终仅LBT成功的leg作为最终的复制传输资源。
107、网络设备向终端设备发送第一指示信息。
其中,第一指示信息用于指示复制传输资源,第一指示信息包括以下至少一种:至少一个RB标识、至少一个复制传输路径的标识、复制传输的数据份数、至少一个第一载波的标识,以及激活/去激活复制传输路径的指示。
可选的,每个复制传输路径的标识包括以下至少一种:RLC实体标识、逻辑信道标识和小区组标识。
由于DC场景内,需要区分不同小区组,有些RLC实体或者逻辑信道无法通过RLC实体标识或逻辑信道标识唯一指示,此时可以通过小区组标识与RLC实体标识,来唯一指示某个RLC实体,以及可以通过小区组标识与逻辑信道标识,来唯一指示某个逻辑信道。
进一步的,在一个小区组中仅包括一个RLC实体或者一个逻辑信道的情况下,也可以仅通过一个小区组标识来标识该一个RLC实体或该一个逻辑信道。
基于上述DC场景的特点,针对除DC场景之外的其他场景(如,CA场景),每个复制传输路径的标识可以包括:RLC实体标识和逻辑信道标识中的至少一个。
针对DC场景,或者DC+CA的场景,每个复制传输路径的标识可以包括:RLC实体标识、逻辑信道标识和小区组标识中的至少一个。
此外,针对DC场景,或者DC+CA的场景,每个复制传输路径的标识可以包括:RLC实体标识、逻辑信道标识中的至少一个。比如不同小区组的标识不同,或者,一个基站仅指示该基站下的复制传输路径。
可选的,每个第一载波的标识为以下标识中的至少一种:载波标识和部分带宽BWP标识。
108、终端设备根据第一指示信息,确定复制传输资源。
其中,网络设备可以将第一指示信息所指示的资源,确定为终端设备的复制传输资源。
本发明实施例提供中,终端设备可以将该LBT结果发送给网络设备,以使得网络设备通过接收到的LBT结果,为终端设备选择复制传输资源,并将选择的复制传输资源指示给终端设备。通过该方案,终端设备可以针对LBT成功的载波,确定一个或多个数据传输路径,如此在采用非授权频谱传输数据时,可以实现将复制后的多份数据通过多个传输路径进行传输。
进一步的,由于NR-U独有的特性,仅在LBT成功时才能在对应的载波上传输数据,因此上述确定复制传输资源的方法中,基于LBT结果,灵活的确定复制传输资源,保证了资源传输的可靠性需求,提高了NR-U系统中的数据传输性能和终端设备的传输性能。
可选的,结合图2,如图3所示,在上述108之后,本发明实施例提供的确定复制传输路径的方法还可以包括下述109和110。
109、终端设备激活至少一个复制传输路径中的目标复制传输路径,和/或,激活至少一个第一载波中的第一目标载波。
110、终端设备激活与目标复制传输路径对应的时频资源,和/或,激活与第一目标载波对应的时频资源。
其中,上述时频资源可以为上行传输的时频资源,例如,可以为配置授权(confige grant,CG)的时频资源,或者动态授权(dynamic grant,DG)的时频资源。
本发明实施例中,在进行数据的复制传输时,可以在上述激活的时频资源上发送上行数据。
可选的,结合图3,如图4所示,在上述107之后,109之前,本发明实施例提供的确定复制传输路径的方法还可以包括:
111、网络设备向终端设备发送第三指示信息。
其中,第三指示信息用于指示激活目标复制传输路径,和/或,指示激活第一目标载波。
可选的,在上述109之后,在上述110之前,终端设备还可以将激活的目标复制传输路径,以及激活的第一目标载波的信息发送给网络设备,而网络设备还可以通过指示信息来指示终端设备激活与目标复制传输路径对应的时频资源,和/或,激活与第一目标载波对应的时频资源。
可选的,结合图4,如图5所示,在上述104之前,还可以包括:
112、网络设备向终端设备发送第五指示信息。
其中,该第五指示信息用于指示复制传输的初始模式。网络设备也可以将该第五指示信息与上述第四指示信息携带在同一个消息中发送给终端设备。
本发明实施例中,指示复制传输的初始模式时,可以指示激活的复制传输路径(即,指示激活的RLC实体或者逻辑信道)。
可选的,在第五信息中还可以指示其他用于复制传输的复制传输资源,本发明实施例不作限定,可以根据实际情况设置。
相应的,在终端设备接收到第五指示信息之后,可以从第五指示信息中获取初始用于复制传输的复制传输资源(例如,激活使用的RLC实体),从而可以激活对应的RLC实体,并通过这些RLC实体进行数据复制传输。
可选的,结合图5,如图6所示,在上述108之后,还可以包括:
113、网络设备向终端设备发送第六指示信息。
其中,第六指示信息用于指示更新复制传输资源。
本发明实施例中,网络设备可以根据不同时段的载波占用情况,重新为终端设备确定复制传输资源,并通过指示信息指示终端设备更新复制传输资源。
可选的,网络设备可以将第六指示信息通过MAC CE发送给终端设备,其中可以指示变更的leg的信息(如,RLC实体标识,或者逻辑信道标识)。
可选的,网络设备还可以发送用于指示终端设备上报LBT结果的指示信息,然后再执行上述113。即,此时可以根据终端设备实时上报的LBT结果,确定需要更新的复制传输资源。
第二种实施方式:由终端设备确定复制传输的资源
如图7所示,提供一种确定复制传输资源的方法,该方法包括:
201、网络设备确定复制传输的配置信息。
202、网络设备向终端设备发送第四指示信息。
203、终端设备配置复制传输路径,以及复制传输路径与RB的对应关系。
204、终端设备对非授权频谱中的目标载波进行LBT检测,得到目标载波的LBT结果。
对于上述201至204的描述,可以参照上述第一种实施方式中对101至104的描述,此处不再赘述。
205、终端设备根据LBT结果和第四指示信息中指示的复制传输的配置信息,确定复制传输资源。
终端设备可以基于检测得到的LBT结果,以及网络设备所指示的复制传输的配置信息,自己确定复制传输资源。
对于205中终端设备确定的复制传输资源的描述,可以参照上述106中确定的复制传输资源的描述,此处不再赘述。
本发明实施例提供中,终端设备可以对非授权频谱中的载波进行LBT检测得到LBT结果,然后终端设备可以根据该LBT结果,选择进行复制传输的资源。通过该方案,非授权频谱中可以针对LBT成功的载波,确定一个或多个数据传输路径,如此在采用非授权频谱传输数据时,可以实现将复制后的多份数据通过多个传输路径进行传输。
上述图7所示的方法,相比于图2所示的方法,给予了终端设备灵活度,减少了由网络设备确定复制传输资源所带来的时延。
可选的,结合图7,如图8所示,在上述205之后,还可以包括下述206。
206、终端设备向网络设备发送LBT结果和复制传输资源的信息。

本发明实施例中,终端设备将复制传输资源的信息发送给网络设备,可以使得网络设备获知终端设备确定的复制传输资源。
可选的,终端设备将LBT结果和复制传输资源的信息发送给网络设备,一方面可以使得网络设备获 知终端设备确定的复制传输资源;另一方面可以使得网络设备在获知终端设备确定的复制传输资源后,根据LBT结果,为终端设备重新指示复制传输资源。
206b、终端设备向网络设备发送LBT结果。
本发明实施例中,终端设备仅将发送LBT结果发送给网络设备,可以使得网络设备获知LBT结果,隐式确定终端设备最终确定的复制传输资源。
可选的,结合图8,如图9所示,在上述205之前,本发明实施例提供的确定复制传输资源的方法还可以包括:
207、网络设备向终端设备发送第二指示信息。
其中,第二指示信息用于指示允许终端设备确定复制传输资源。
在终端设备接收到第二指示信息之后,可以获知网络设备允许终端设备自己确定复制传输资源,此时终端设备可以继续执行上述205。
如图9中所示,在上述205之后,本发明实施例提供的确定复制传输资源的方法还可以包括:
208、网络设备向终端设备发送第三指示信息。
209、终端设备激活至少一个复制传输路径中的目标复制传输路径,和/或,激活至少一个第一载波中的第一目标载波。
210、终端设备激活与目标复制传输路径对应的时频资源,和/或,激活与第一目标载波对应的时频资源。
针对上述208至210的描述,可以参照上述对上述111、109和110的描述,此处不再赘述。
可选的,结合图9,如图10所示,在上述204之前,还可以包括:
211、网络设备向终端设备发送第五指示信息。
针对上述211的描述,可以参照上述对112的描述,此处不再赘述。
可选的,结合图10,如图11所示,在上述205之后,还可以包括:
212、网络设备向终端设备发送第六指示信息。
针对上述212的描述,可以参照上述对113的描述,此处不再赘述。
可选的,在终端设备已经确定复制传输资源之后,此时终端设备可以采用确定出的复制传输资源,向网络设备传输数据。
可选的,网络设备还可以发送用于指示终端设备上报LBT结果的指示信息,然后在执行上述212。即,此时可以根据终端设备实时上报的LBT结果,确定需要更新的复制传输资源。
本发明实施例中,终端设备除了可以自己确定上述复制传输资源之外,还可以自己确定上述的复制配置信息、以及为自己确定复制传输的初始模式等。
在终端设备确定了复制传输资源之后,终端设备可以根据确定的复制传输资源传输数据。
下面具体对分别对DC和CA两种场景下的复制传输方式进行说明。
1、DC场景
DC场景下的复制传输方的协议架构如下图12中的DRB ID 2所示。终端设备中的PDCP实体下面关联着两个不同的RLC实体,两个关联的不同RLC实体关联到不同的MAC实体,一个MAC实体对应主小区组(Master Cell group,MCG),一个MAC实体对应辅小区组(Secondary Cell group,SCG)。对于上下行来说,PDCP将PDCP PDU(协议数据单元)复制为相同的两份,两个PDCP经过不同CG的RLC实体,传输至MAC实体,再经过空口到达基站(上行)相应的MAC实体,然后通过该MAC实体传输至相应的RLC实体,最后再汇聚到PDCP,PDCP层检测到两个PDCP PDU为相同的复制版本(比如,通过这两个PDCP PDU具有相同的SN来判断其为相同的复制版本)时,可以丢弃其中一个,再将另外一个递交到高层(需要注意的是,复制PDCP PDU不一定同时到达PDCP层)。
2、CA场景
CA场景下的复制传输方式的协议架构如下图12中的DRB ID 1或者DRB ID 3所示。终端设备中的一个PDCP实体下面关联着两个不同的RLC实体,两个关联的不同RLC实体关联到同一个MAC实体。对 于上下行来说,将PDCP PDU复制为相同的两份,两个PDCP经过不同的RLC实体传输至同一个MAC实体,再经过空口到达基站(上行)相应的MAC实体,RLC实体,最后再汇聚到PDCP。PDCP层检测到两个PDCP PDU为相同的复制版本(比如,通过这两个PDCP PDU具有相同的SN来判断其为相同的复制版本)时,可以丢弃其中一个,再将另外一个递交到高层(需要注意的是,复制PDCP PDU不一定同时到达PDCP层)。
本发明实施例中,针对应用于确定下行(如,网络设备向终端设备传输数据)的复制传输资源的方法,与上述确定上行的复制传输资源的方法类似。网络设备可以对载波进行LBT侦听,并根据得到的LBT结果,确定网络设备与用于复制传输的复制传输资源。
