具体实施方式
为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案,并不构成对本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
请参考图1,其示出了本申请一个实施例提供的网络架构的示意图。该网络架构可以包括:核心网11、接入网12和终端设备13。
核心网11中包括若干核心网设备。核心网设备的功能主要是提供用户连接、对用户的管理以及对业务完成承载,作为承载网络提供到外部网络的接口。例如,5G(5th Generation,第五代移动通信技术)NR(New Radio,新空口)系统的核心网中可以包括AMF(Access and Mobility Management Function,接入和移动性管理功能)实体、UPF(User Plane Function,用户平面功能)实体和SMF(Session Management Function,会话管理功能)实体等设备。
接入网12中包括若干接入网设备14。5G NR系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network,新一代无线接入网)。接入网设备14是一种部署在接入网12中用以为终端设备13提供无线通信功能的装置。接入网设备14可以包括各种形式的宏基站,微基站,中继站,接入点等等。在采用不同的无线接入技术的系统中,具备接入网设备功能的设备的名称可能会有所不同,例如在5G NR系统中,称为gNodeB或者gNB。随着通信技术的演进,“接入网设备”这一名称可能会变化。为方便描述,本申请实施例中,上述为终端设备13提供无线通信功能的装置统称为接入网设备。
终端设备13的数量通常为多个,每一个接入网设备14所管理的小区内可以分布一个或多个终端设备13。终端设备13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备,以及各种形式的用户设备、移动台(Mobile Station,MS)等等。为方便描述,上面提到的设备统称为终端设备。接入网设备14与核心网设备之间通过某种空中技术相互通信,例如5G NR系统中的NG接口。接入网设备14与终端设备13之间通过某种空中技术互相通信,例如Uu接口。
终端设备13和终端设备13(例如车载设备与其它设备(如其它车载设备、手机、RSU(Road Side Unit,路侧单元)等))之间可以通过直连通信接口(如PC5接口)互相通信,相应地,该基于直连通信接口建立的通信链路可以称为直连链路或SL。SL传输即为终端设备与终端设备之间通过侧行链路直接进行通信数据传输,不同于传统的蜂窝系统中通信数据通过接入网设备接收或者发送,SL传输具有时延短、开销小等特点,适合用于地理位置接近的两个终端设备(如车载设备和地理位置接近的其它周边设备)之间的通信。需要说明的是,在图1中,仅以V2X(vehicle to everything,车联网)场景下的车对车通信为示例,SL技术可以应用于各种终端设备之间直接进行通信的场景。或者说,本申请中的终端设备是指任意一种利用SL技术通信的设备。
本申请实施例中的“5G NR系统”也可以称为5G系统或者NR系统,但本领域技术人员可以理解其含义。本申请实施例描述的技术方案可以适用于5G NR系统,也可以适用于5G NR系统后续的演进系统。
请参考图2,其示出了U2U中继传输场景(或者说端到端中继业务)的网络架构的示意图。在U2U中继传输场景下,包括第一远端终端设备21、中继终端设备22和第二远端终端设备23。第一远端终端设备21和第二远端终端设备23通过中继终端设备22进行端到端的业务传输。第一远端终端设备21和中继终端设备22之间可以通过基于直连通信接口(如PC5接口)建立的侧行链路直接进行通信。第二远端终端设备23和中继终端设备22之间也可以通过基于直连通信接口(如PC5接口)建立的侧行链路直接进行通信。
在U2U中继传输场景下,涉及如下几个概念:
1.源远端终端设备:是指第一远端终端设备和第二远端终端设备中,发送直接通信请求消息的终端设备;
2.目标远端终端设备:是指第一远端终端设备和第二远端终端设备中,接收直接通信请求消息的终端设备;
3.发送端终端设备:是指第一远端终端设备和第二远端终端设备中发送业务数据的终端设备;
4.接收端终端设备:是指第一远端终端设备和第二远端终端设备中接收业务数据的终端设备。
示例性地,假设在图2所示的U2U中继传输场景中,由第一远端终端设备21向第二远端终端设备23 发送直接通信请求消息,该直接通信请求消息用于请求建立端到端的直连链路;相应地,第二远端终端设备23接收来自第一远端终端设备21的直接通信请求消息。那么,第一远端终端设备21为源远端终端设备,第二远端终端设备23为目标远端终端设备。
示例性地,假设在图2所示的U2U中继传输场景中,由第二远端终端设备23向第一远端终端设备21发送直接通信请求消息,该直接通信请求消息用于请求建立端到端的直连链路;相应地,第一远端终端设备21接收来自第二远端终端设备23的直接通信请求消息。那么,第一远端终端设备21为目标远端终端设备,第二远端终端设备23为源远端终端设备。
示例性地,假设在图2所示的U2U中继传输场景中,由第一远端终端设备21向第二远端终端设备23发送业务数据,相应地,第二远端终端设备23接收来自第一远端终端设备21的业务数据。那么,第一远端终端设备21为发送端终端设备,第二远端终端设备23为接收端终端设备。
示例性地,假设在图2所示的U2U中继传输场景中,由第二远端终端设备23向第一远端终端设备21发送业务数据,相应地,第一远端终端设备21接收来自第二远端终端设备23的业务数据。那么,第一远端终端设备21为接收端终端设备,第二远端终端设备23为发送端终端设备。
另外,源远端终端设备可以作为发送端终端设备,也可以作为接收端终端设备;同样地,目标远端终端设备可以作为发送端终端设备,也可以作为接收端终端设备。对于第一远端终端设备和第二远端终端设备中的任意一个远端终端设备来说,其可以在发送端终端设备和接收端终端设备这两个角色之间进行切换,或者同时具备发送端终端设备和接收端终端设备这两个角色。
请参考图3,其示出了本申请一个实施例提供的通信方法的流程图。该方法可应用于图1和图2所示的网络架构中。该方法可以包括如下步骤310:
步骤310,端到端中继业务中的第一设备,将端到端中继业务相关的第一配置参数,发送给端到端中继业务中的第二设备。
相应地,端到端中继业务中的第二设备,接收来自端到端中继业务中的第一设备的,上述端到端中继业务相关的第一配置参数。
也就是说,第一设备将第一业务相关的第一配置参数发送给第二设备,第一业务为第一远端终端设备、中继终端设备和第二远端终端设备之间的端到端中继业务。相应地,第二设备接收第一设备发送的第一业务相关的第一配置参数。
端到端中继业务包括第一远端终端设备、中继终端设备和第二远端终端设备参与。在一些实施例中,第一设备为第一远端终端设备、中继终端设备和第二远端终端设备中的其中之一。在一些实施例中,第二设备为第一远端终端设备、中继终端设备和第二远端终端设备中不同于第一设备的终端设备。
示例性地,第一设备为第一远端终端设备,第二设备为中继终端设备和/或第二远端终端设备。
示例性地,第一设备为中继终端设备,第二设备为第一远端终端设备和/或第二远端终端设备。
示例性地,第一设备为第二远端终端设备,第二设备为中继终端设备和/或第一远端终端设备。
在本申请实施例中,第一配置参数是指端到端中继业务相关的配置参数,如QoS(Quality of Service,服务质量)参数或者其他参数,具体可参见下文实施例中的介绍说明。第一配置参数由参与该端到端中继业务的某一终端设备或该终端设备的网络设备配置,并由该终端设备发送给参与该端到端中继业务的其他终端设备,从而实现该第一配置参数在参与该端到端中继业务的多个终端设备之间进行协商同步。

在一些实施例中,第一配置参数由第一设备确定。也即,由第一设备配置该第一配置参数。
在一些实施例中,第一配置参数由第一设备的网络设备确定。也即,由第一设备的网络设备配置该第一配置参数。例如,第一配置参数由第一设备的接入网设备(如基站)确定。第一设备的网络设备可以将第一配置参数发送给第一设备,而后由第一设备将第一配置参数发送给第二设备。例如,第一设备的网络设备通过RRC(Radio Resource Control,无线资源控制)消息或系统广播消息,将第一配置参数发送给第一设备。
在一些实施例中,在第一设备处于RRC连接态的情况下,第一配置参数可以由第一设备的网络设备确定,或者也可以由第一设备确定。
在一些实施例中,在第一设备处于非连接态的情况下,如第一设备处于RRC空闲态或RRC非激活态的情况下,第一配置参数可以由第一设备确定。
在一些实施例中,远端终端设备(包括第一远端终端设备和/或第二远端终端设备)和中继终端设备之间,可以通过基于直连通信接口建立的侧行链路进行通信。第一远端终端设备和第二远端终端设备之间所需要传输的信息,可以通过中继终端设备进行中转转发。

在一些实施例中,在接受第一配置参数的情况下,第二设备向第一设备发送第一反馈消息,该第一反馈消息用于指示第二设备接受第一配置参数。相应地,第一设备接收第二设备发送的第一反馈消息。
在一些实施例中,在拒绝(或者说不接受)第一配置参数的情况下,第二设备向第一设备发送第二反馈消息,该第二反馈消息用于指示第二设备拒绝第一配置参数。相应地,第一设备接收第二设备发送的第二反馈消息。
在一些实施例中,如图4所示,上述步骤310之后还包括如下步骤320:在拒绝(或者说不接受)第一配置参数的情况下,第二设备向第一设备发送重配置请求消息,该重配置请求消息用于请求对第一配置参数进行重配置。相应地,第一设备接收第二设备在拒绝第一配置参数的情况下发送的重配置请求消息。
在一些实施例中,重配置请求消息中包括端到端中继业务相关的第二配置参数。第二配置参数是与第一配置参数对应的配置项相同,但参数值不同的参数。例如,第一配置参数包括QoS参数,假设第一配置参数中的QoS参数的参数值为A,则第二配置参数也可以包括QoS参数,且第二配置参数中的QoS参数 的参数值为B,B不同于A。也就是说,在第二设备或第二设备的网络设备确定拒绝第一配置参数的情况下,在一些实施例中,还可以向第一设备反馈第二配置参数,该第二配置参数是第二设备可接受的配置参数,从而使得第一设备能够根据该第二配置参数明确获知第二设备所期望或支持的配置参数,据此对第一配置参数进行重配置,有助于提升参数配置的准确性,且简化设备间的协商流程,提升参数配置的效率。
在一些实施例中,上述第一反馈消息、第二反馈消息、重配置请求消息中的至少之一,可以是PC5-S消息,或者PC5-RRC消息,本申请对此不作限定。
在一些实施例中,第二设备的网络设备可以通过RRC消息,或下行MAC CE(Medium Access Control Control Element,媒体接入层控制单元)消息,或者DCI(Downlink Control Information,下行控制信息)向第二设备发送用于指示接受或拒绝第一配置参数的响应消息和/或第二配置参数。另外,上述第二配置参数可以和用于指示接受或拒绝第一配置参数的响应消息在同一消息中一起发送,也可以在两条消息中分别发送,本申请对此不作限定。
在一些实施例中,第二配置参数由第二设备确定。也即,由第二设备配置该第二配置参数。
在一些实施例中,第二配置参数由第二设备的网络设备确定。也即,由第二设备的网络设备配置该第二配置参数。例如,第二配置参数由第二设备的接入网设备(如基站)确定。第二设备的网络设备可以将第二配置参数发送给第二设备,而后由第二设备将第二配置参数发送给第一设备。例如,第二设备的网络设备通过RRC消息,将第二配置参数发送给第二设备。
在一些实施例中,在第二设备处于RRC连接态的情况下,第二配置参数可以由第二设备的网络设备确定,或者也可以由第二设备确定。
在一些实施例中,在第二设备处于非连接态的情况下,如第二设备处于RRC空闲态或RRC非激活态的情况下,第二配置参数可以由第二设备确定。
在一些实施例中,第一设备接收到重配置请求消息之后,第一设备向第二设备发送重配置后的第一配置参数。可选地,如果第一设备接收到第二配置参数,第一设备可以根据第二配置参数,确定重配置后的第一配置参数。例如,第一设备直接将第二配置参数确定为重配置后的第一配置参数,或者,第一设备也可以根据第二配置参数并结合自身的能力信息,确定重配置后的第一配置参数。
在一些实施例中,第一设备根据第一定时器,确定端到端中继业务相关的配置参数是否配置成功。第一设备侧可以维护第一定时器,依据该第一定时器确定端到端中继业务相关的配置参数是否配置成功。例如,第一设备在向第二设备发送第一配置参数的同时或者之后,启动第一定时器,如果在第一定时器超时之前接收到来自第二设备的第一反馈消息,或者未接收到来自第二设备的第二反馈消息,则第一设备确定端到端中继业务相关的配置参数配置成功;否则,如果在第一定时器超时的时候仍未接收到第一反馈消息,或者在第一定时器超时之前接收到来自第二设备的第二反馈消息,则第一设备确定端到端中继业务相关的配置参数配置失败。
在一些实施例中,第二设备根据第二定时器,确定端到端中继业务相关的配置参数是否配置成功。第二设备侧可以维护第二定时器,依据该第二定时器确定端到端中继业务相关的配置参数是否配置成功。例如,第二设备向第一设备发送重配置请求消息的同时或者之后,启动第二定时器,如果在第二定时器超时之前接收到来自第一设备的重配置后的第一配置参数,则第二设备确定端到端中继业务相关的配置参数配置成功;否则,如果在第一定时器超时的时候仍未接收到来自第一设备的重配置后的第一配置参数,则第二设备确定端到端中继业务相关的配置参数配置失败。
在本实施例中,针对端到端中继业务,由其中一方的终端设备将业务相关的配置参数,发送给参与端到端中继的其他终端设备,实现了配置参数在业务的各个参与方之间的同步协商,从而有助于提升端到端中继业务的稳定性和可靠性。
另外,第二设备在接收到第一设备发来的第一配置参数之后,若拒绝该第一配置参数,可以向第一设备发送重配置请求消息,以触发第一设备进行参数的重配置,以达到协商的效果。另外,重配置请求消息中可以携带第二设备所期望或支持的第二配置参数,这样使得第一设备可以据此对第一配置参数进行重配置,有助于提升参数配置的准确性,且简化设备间的协商流程,提升参数配置的效率。

通过上述方式,针对端到端中继场景,远端终端设备和中继终端设备之间的侧行链路的单跳RLC配置参数,可以由当前侧行链路的发送端配置,也可以由另一侧行链路的发送端配置,实现了RLC配置的灵活性。
在一些实施例中,第一配置参数包括第一QoS参数,第一QoS参数包括第一远端终端设备和第二远端终端设备之间的端到端QoS参数。第二设备在接收到上述第一配置参数之后,可以向第一设备发送单跳QoS参数;相应地,第一设备接收第二设备发送的单跳QoS参数。单跳QoS参数包括第二QoS参数和/或第三QoS参数;其中,第二QoS参数包括第一远端终端设备和中继终端设备之间的QoS参数,第三QoS参数包括第二远端终端设备和中继终端设备之间的QoS参数。

另外,第一设备和第二设备可以是如上情况1~5中的任意一种。
在一些实施例中,单跳QoS参数由第二设备确定。也即,由第二设备配置该单跳QoS参数。
在一些实施例中,单跳QoS参数由第二设备的网络设备确定。也即,由第二设备的网络设备配置该单跳QoS参数。例如,单跳QoS参数由第二设备的接入网设备(如基站)确定。第二设备的网络设备可以将单跳QoS参数发送给第二设备,而后由第二设备将单跳QoS参数发送给第一设备。例如,第二设备的网络设备通过RRC消息,将单跳QoS参数发送给第二设备。
在一些实施例中,在第二设备处于RRC连接态的情况下,单跳QoS参数可以由第二设备的网络设备确定,或者也可以由第二设备确定。
在一些实施例中,在第二设备处于非连接态的情况下,如第二设备处于RRC空闲态或RRC非激活态的情况下,单跳QoS参数可以由第二设备确定。
在一些实施例中,第一设备接收第二设备发送的单跳QoS参数之后,还包括:第一设备确定是否接受单跳QoS参数。
在一些实施例中,第一设备接收第二设备发送的单跳QoS参数之后,还包括:第一设备向第一设备的网络设备发送请求消息,该请求消息用于请求确认是否接受单跳QoS参数;第一设备接收第一设备的网络设备发送的响应消息,该响应消息用于指示接受或拒绝单跳QoS参数。
在一些实施例中,在第一设备处于RRC连接态的情况下,是否接受第二设备提供的单跳QoS参数可以由第一设备的网络设备确定,或者也可以由第一设备确定。
在一些实施例中,在第一设备处于非连接态的情况下,如第一设备处于RRC空闲态或RRC非激活态的情况下,是否接受第二设备提供的单跳QoS参数可以由第一设备确定。
在一些实施例中,在接受第二设备提供的单跳QoS参数的情况下,第一设备可以向第二设备发送用于指示接受该单跳QoS参数的反馈消息;在拒绝第二设备提供的单跳QoS参数的情况下,第一设备可以向第二设备发送用于指示拒绝或重配置该单跳QoS参数的反馈消息。
在一些实施例中,在拒绝第二设备提供的单跳QoS参数的情况下,第一设备还可以向第二设备发送建议的单跳QoS参数,以便第二设备能够基于该建议的单跳QoS参数进行重配置,从而有助于提升单跳QoS参数的协商效率。
通过上述方式,针对端到端中继业务,由端到端QoS参数的接收端执行QoS切分,对单跳QoS参数进行配置。并且,实现了单跳QoS参数在参与端到端中继业务的各个终端设备之间的协商同步。
在一些实施例中,在第一设备为中继终端设备,且第一设备处于网络覆盖外的情况下,上述方法还包括:在同一承载对应多组QoS参数,且每一组QoS参数对应于一组配置信息的情况下,第一设备根据各组配置信息的选择优先级,选择承载对应的配置信息。其中,配置信息包括以下至少之一:SRAP配置参数、RLC配置参数;选择优先级与以下至少之一有关:QoS参数中的PQI(PC5 5G QoS Identifier,PC5接口上的5G服务质量标识)、QoS参数中的PDB(Packet Delay Budget,包时延预算)、显式的优先级信息。
若SRAP和/或RLC配置参数是根据端到端QoS参数为粒度进行配置的,则会存在虽然QoS参数与SRAP和/或RLC配置参数是一对一映射的,但是与承载配置是多对一映射的。也即,同一承载可以对应多组QoS参数,同一承载可以对应多组SRAP和/或RLC配置参数。因此,若中继终端设备根据承载ID(Identifier,标识符)选择SRAP和/或RLC配置参数时,则会有多组SRAP和/或RLC配置参数可供选择,则此时需要有额外准则辅助中继终端设备选择对应此承载合适的SRAP和/或RLC配置参数。可选地,所述准则可以是以下方法至少之一:
(1)根据QoS参数中的PQI进行选择,即PQI数值越低则认为对应SRAP和/或RLC配置参数的优先级越高,则需要优先选择对应的SRAP和/或RLC配置参数;
(2)根据QoS参数中的PDB进行选择,即PDB数值越低则认为对应SRAP和/或RLC配置参数的优先级越高,则需要优先选择对应的SRAP和/或RLC配置参数;
(3)增加显式的优先级信息,所述优先级信息可以反映出对应SRAP和/或RLC配置参数的优先级,需要选择优先级更高的SRAP和/或RLC配置参数。
在一些实施例中,若通过上述准则仍然选择出多组SRAP和/或RLC配置参数,则根据终端实现选择出一组SRAP和/或RLC配置参数。
通过上述方法,明确了覆盖外中继中端设备如何根据端到端QoS信息推导SRAP和/或RLC配置参数的方式。
在一些实施例中,不同的PDB等级对应于不同的配置信息,每个PDB等级对应于一个PDB取值范围。
针对QoS切分影响较大的参数为PDB,PDB会影响相关SRAP和/或RLC配置参数的配置,但目前PDB的取值范围是从0-1023,若针对1024个PDB值分别配置SRAP和/或RLC配置参数则粒度过于精细,因此,可以考虑以下方式为不同等级的PDB进行SRAP和/或RLC相关参数的配置。
在一些实施例中,将1024个PDB取值进行等级划分,所述等级划分中包含第一数目的PDB等级,所述等级与PDB真实取值的对应关系为一对多对应。进一步地,针对PDB等级配置对应的SRAP和/或RLC配置参数,具体地在相关SRAP和/或RLC配置参数中携带PDB等级信息。则中继终端设备可以根据所述PDB取值信息判断出对应的PDB等级,从而选择出对应的SRAP和/或RLC配置参数。
通过上述方法,明确了覆盖外中继终端设备如何根据QoS切分信息推导出相关SRAP和/或RLC配置参数的方式。
