本申请要求于2021年07月28日提交的申请号为2021108600441,发明名称为“QoS参数配置方法、设备、装置及存储介质”的中国专利申请的优先权,其通过引用方式全部并入本文。
技术领域
本公开涉及无线通信技术领域,尤其涉及一种QoS参数配置方法、设备、装置及存储介质。
背景技术
传统的无线通信采用蜂窝网络通信方式,即终端(也称用户设备,User Equipment,UE)和网络设备(例如下一代基站(next generation NodeB,gNB))通过Uu接口进行上下行数据/控制信息的传输。为了扩展网络覆盖,一种解决方案就是引入终端到网络中继(UE-to-Network Relay)。UE-to-Network Relay可以是一个具有中继功能的终端,对于UE-to-Network Relay,中继终端和网络设备之间的接口使用Uu接口,和被中继终端(可称为远端终端或Remote UE)之间使用直接通信接口(也称为Sidelink接口或接近通信端口5(Proximity Communication Port 5,PC5)接口),中继终端和网络设备之间的链路对远端终端而言可以称为回程链路(Backhaul link,BH),而中继终端和远端终端之间可通过直接通信链路(也称为Sidelink或者PC5)进行数据传输。
对于L2 UE-to-Network Relay场景,其承载或数据无线承载(Data Radio Bearer,DRB)是端到端的(即远端终端和网络设备之间直接建立),而低层(比如无线链路控制层(Radio Link Control,RLC)、媒体访问控制层(Media Access Control,MAC)或物理层(Physical,PHY))则是hop by hop的,所述hop by hop也就是基于每一跳的,具体的网络设备和中继终端之间的链路为一跳,中继终端和远端终端之间是另一跳。由于远端终端和网络设备之间存在两段链路即Sidelink和Backhaul link(即中继终端和网络设备之间的Uu  link),这种场景下如何保证远端终端和网络设备端到端承载/DRB的服务质量(Quality of Service,QoS)是目前亟需解决的技术问题。

为了便于更加清晰地理解本公开各实施例,首先对一些相关的背景知识进行如下介绍。
(1)蜂窝网络通信
图1为现有技术提供的传统无线通信方式示意图,如图1所示,传统的无线通信采用蜂窝网络通信方式,即终端和网络设备通过Uu接口进行上下行数据/控制信息的传输。
(2)直接通信
图2为现有技术提供的设备到设备直接通信方式示意图,如图2所示,直接通信是指邻近的终端可以在近距离范围内通过直接通信链路(也称为 Sidelink或者PC5)进行数据传输的方式。Sidelink链路对应的无线接口称为直接通信接口(也称为Sidelink接口或者PC5接口)。
(3)中继
图3为现有技术提供的UE-to-Network Relay示意图,如图3所示,为了扩展网络覆盖,可以考虑引入UE-to-Network Relay(终端到网络设备中继)。中继本身可以是具有中继功能的终端(也称为sidelink Relay),对于UE-to-Network Relay,中继终端和网络设备之间的接口使用Uu接口,和被中继终端(可称为远端终端)之间使用Sidelink接口(也称为直接通信接口,或者旁路接口或者PC5接口),中继终端和网络设备之间的链路(Uu link)对远端终端而言可以称为回程链路。
UE-to-Network Relay根据协议栈架构的不同,又分为L2 UE-to-Network Relay和L3 UE-to-Network Relay。图4为现有技术提供的L2 UE-to-Network Relay用户面协议栈示意图,如图4所示,在L2 UE-to-Network Relay场景下承载或DRB是端到端的(即Remote UE和gNB之间直接建立),而低层(比如RLC、MAC或PHY)则是hop by hop的。
对于L2 UE-to-Network Relay场景,远端终端和网络设备之间由于存在两段链路:Sidelink和Uu link(也称为backhaul link或者Uu backhaul link),这种场景下如何保证远端终端和网络设备端到端承载/DRB的QoS是亟需解决的问题。对于L2 UE-to-UE Relay场景,也存在同样的问题。
针对上述问题,本公开各实施例提供一种中继场景QoS管理方案,可以保证L2 sidelink Relay场景下的端到端承载/DRB的QoS。
图5为本公开实施例提供的QoS参数配置方法的流程示意图之一,该方法应用于QoS管理节点,如图5所示,该方法包括如下步骤:
步骤500、确定中继终端和QoS管理节点的目标通信对端之间目标传输方向上的直接通信链路接口使用的QoS参数。
具体地,本公开实施例中,QoS管理节点,也可以称为端到端QoS管理节点,是对QoS参数进行管理配置的网络节点,可以是UE-to-Network Relay场景中的网络设备(例如基站);也可以是UE-to-UE Relay场景中每个传输 方向上的发送终端或任一远端终端。
为保证L2 sidelink Relay场景下的端到端承载/DRB的QoS,QoS管理节点需要确定中继终端和QoS管理节点的目标通信对端之间目标传输方向上的sidelink接口使用的QoS参数,具体确定方式可以取决于QoS管理节点的实现,在此不做限制。
其中,目标传输方向可以是指中继终端至QoS管理节点的目标通信对端的传输方向,也可以是指QoS管理节点的目标通信对端至中继终端的传输方向,还可以包括中继终端和QoS管理节点的目标通信对端之间的每个传输方向。
以UE-to-Network Relay场景为例,上述目标传输方向,可以是指中继终端至远端终端的传输方向(即下行传输方向),也可以是指远端终端至中继终端的传输方向(即上行传输方向),还可以是指下行和上行传输方向。
可选地,所述QoS参数可以包括但不限于以下任一项或其组合:

步骤501、向中继终端和/或目标通信对端发送QoS参数。
具体地,QoS管理节点确定中继终端和QoS管理节点的目标通信对端之间目标传输方向上的sidelink接口使用的QoS参数后,可以将该QoS参数发送至中继终端和/或QoS管理节点的目标通信对端,从而中继终端和/或QoS管理节点的目标通信对端可以根据接收到的QoS参数,进行中继终端和QoS管理节点的目标通信对端之间目标传输方向上的sidelink接口的数据传输。
以UE-to-Network Relay场景为例,如果仅有下行数据传输需求,则网络设备确定中继终端和远端终端之间下行传输方向上的sidelink接口使用的QoS参数后,可以将该QoS参数发送至中继终端,从而中继终端接收到该QoS参数后,可以基于该QoS参数进行中继终端和远端终端之间的下行数据传输;如果仅有上行数据传输需求,则网络设备确定中继终端和远端终端之间上行 传输方向上的sidelink接口使用的QoS参数后,可以将该QoS参数发送至远端终端,从而远端终端接收到该QoS参数后,可以基于该QoS参数进行远端终端和中继终端之间的上行数据传输;如果既有下行数据传输需求又有上行数据传输需求,则网络设备确定中继终端和远端终端之间下行和上行传输方向上的sidelink接口使用的QoS参数后,可以将QoS参数分别发送至中继终端和远端终端。
本公开实施例提供的QoS参数配置方法,由端到端QoS管理节点确定sidelink接口使用的QoS参数,并将该QoS参数发送至中继终端和/或QoS管理节点的目标通信对端,从而中继终端和/或QoS管理节点的目标通信对端可以基于该QoS参数进行sidelink接口的数据传输,保证了L2 sidelink Relay场景下的端到端承载/DRB的QoS。
