具体实施方式
为易于理解本申请的实施例,对本申请实施例所涉及的部分术语或概念作简要说明。
1、传输优先级:主要是指分配给一个消息单元的等级。示例性的,传输优先级决定了该消息单元被路径控制组件选择的优先级,以便转发到路由中的下一个节点。示例性的,该传输优先级的取值包括:低、中、高和网络。
2、中继侧行链路(relay sidelink,relay SL)主要是指传输中继业务(如数据或信令等)的侧行链路。其中,中继业务可以理解为中继设备为远端设备向网络设备转发的业务,或者可以是中继设备为网络设备向远端设备转发的业务。
3、普通侧行链路(normal sidelink,normal SL)或者称为非中继侧行链路主要是指传输正常或者非中继业务的侧行链路。
4、中继上行链路(relay uplink,relay UL)主要是指传输中继业务的上行通信链路。
5、普通上行链路(normal uplink,normal UL)主要是指传输正常或者非中继业务的上行通信链路。
6、目的地址(destination)
在单播通信中,目的地址可用于标识一个接收终端;在组播通信中,目的地址可用于标识一个组;在广播通信中,目的地址可用于标识一个业务。可以理解,目的地址可以是目的层2标识(destination L2 ID)。或者说,目的层2标识是目的地址的一例。
7、Sidelink上支持广播通信、单播通信和组播通信。
广播通信类似于基站广播系统信息,即终端不做加密对外发送广播业务的数据,任何在有效接收范围内的其他终端,如果对该广播业务感兴趣都可以接收该广播业务的数据。
单播通信类似于终端与基站之间建立RRC连接之后进行的数据通信,需要终端之间在先建立单播连接。在建立单播连接之后,上述终端可以基于协商的标识进行数据通信,该数据可以是加密的,也可以是不加密的。相比于广播通信,在单播通信中,一般是建立了单播连接的终端之间进行单播通信。
组播通信是指通信组内所有终端之间的通信,组内任一终端都可以收发该组播业务的数据。
为了更清楚、完整介绍本申请的技术方案,以下结合附图对本申请部分实施例进行说明。
图1A为本申请实施例适用的一种网络架构100示意图。如图1A所示,远端设备(图中示出远端设备110)可接入到无线网络,以通过无线网络获取外网(例如因特网)的服务,或者通过中继设备(图中示出中继设备130)与无线网络进行通信。该无线网络包括网络设备(或者说无线接入网(radio access network,RAN)设备,图中示出网络设备140),其中网络设备140用于将远端设备110和中继设备130接入到无线网络。可选的,中继设备130可以通过无线接口(如Uu口)与网络设备140进行通信,远端设备110可以通过无线接口(如PC5口)与中继设备130进行通信。远端设备110可以通过多个中继设备(例如中继设备120和中继设备130)的中继接入到网络设备140。
应理解,图1A所示的通信系统中各个设备的数量仅作为示意,本申请实施例并不限于此,实际应用中在通信系统中还可以包括更多的远端终端110、更多的RAN设备,还可以包括其它设备。例如,虽然未示出,但除图1A所示网络功能实体外,图1A所示的网络架构100还可以包括其他功能实体,如:核心网网元等,不予限制。示例性的,图1A可以应用于层2(layer 2)的终端到网络中继(UE to network relay),也可以应用于层3的终端到网络中继(UE to network relay)。
示例性的,图1A中的远端设备可以为远端用户设备(remote user equipment,remote UE)或者称为远端终端,如:可以为可穿戴设备(智能手表、智能手环等),还可以为智能家具(或家电)、车联网中的汽车、工业互联网中的机械手臂、智能加油设备等其他距离无线接入网设备较远、需要通过中继设备与无线接入网设备连接的设备。
图1A中的中继设备可以为中继用户设备(relay user equipment,relay UE)或者称为中继终端,如:可以是能够接收网络设备调度和指示信息的无线终端设备,无线终端设备可以是指向用户提供语音和/或数据连通性的设备,或具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。终端设备可以经无线接入网(如,radio access network,RAN)与一个或多个核心网或者互联网进行通信,终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话,手机(mobile phone))、计算机和数据卡,例如,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言和/或数据。无线终端设备也可以称为系统、移动站(mobile station)、移动台(mobile station,MS)、远程站(remote station)、接入点(access point,AP)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户站(subscriber station,SS)、用户端设备(customer premises equipment,CPE)、终端(terminal)、用户设备(user equipment,UE)、移动终端(mobile terminal,MT)等。终端设备也可以是 可穿戴设备(智能手表、智能手环等),还可以为智能家具(或家电)、车联网中的汽车、工业互联网中的机械手臂、智能加油设备等以及下一代通信系统,例如,第五代(5th generation,5G)通信系统中的终端设备或者未来演进的公共陆地移动网络(public land mobile network,PLMN)中的终端设备等。中继设备也可以是路边的基础设施。
图1A中的网络设备可以是无线网络中的设备,例如网络设备可以为将终端接入到无线网络的无线接入网(radio access network,RAN)节点(或设备),又可以称为基站。目前,一些RAN设备的举例为:5G通信系统中的新一代基站(generation Node B,gNodeB)、传输接收点(transmission reception point,TRP)、演进型节点B(evolved Node B,eNB)、节点B(Node B,NB)、家庭基站(例如,home evolved NodeB,或home Node B,HNB)、基带单元(base band unit,BBU),或无线保真(wireless fidelity,Wi-Fi)接入点(access point,AP)等。另外,在一种网络结构中,网络设备可以包括集中单元(centralized unit,CU)节点、或分布单元(distributed unit,DU)节点、或包括CU节点和DU节点的RAN设备。此外,在其它可能的情况下,网络设备可以是其它为终端设备提供无线通信功能的装置。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。为方便描述,本申请实施例中,为终端设备提供无线通信功能的装置称为网络设备或接入网设备。
上述图1A所示意的网络架构可以适用于各种无线接入技术的通信系统中,例如可以是长期演进(long term evolution,LTE)通信系统,也可以是5G(或者称为新无线(new radio,NR)通信系统,也可以是LTE通信系统与5G通信系统之间的过渡系统,该过渡系统也可以称为4.5G通信系统,当然也可以是未来的通信系统。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的说明本申请实施例的技术方案,并不构成对于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,随着通信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。
需要说明的是,上述图1A架构中的网元、各个网元之间的接口名字以及各个协议栈的命名只是一个示例,具体实现中网元、网元之间的接口名字以及协议栈能为其他名字,本申请实施例对此不作具体限定。
终端与无线接入网设备之间通过无线通信接口(如Uu接口)进行通信时,由于网络覆盖有限以及终端的硬件能力不足等原因,通信距离会受到限制,因此引入了中继技术。举例而言,在中继技术中,规定远端设备(例如第二终端)可以通过中继设备(例如第一终端)与网络设备(例如基站)通信。例如,当远端设备需要向基站传输业务(如数据、信令)时,远端设备可以通过远端设备与中继设备间的无线通信接口(如PC5接口)向中继设备发送数据,中继设备可以通过中继设备与基站间的无线通信接口(如Uu接口)向基站发送远端设备的数据。相对应的,当基站需要向远端设备发送数据时,基站也可以通过中继设备将数据发送给远端设备。
当具有多个或者多个种类的传输业务时(例如存在多个侧行传输业务,或者存在侧行传输业务和上行业务),确定出传输优先级有利于提升Sidelink的传输效率,如何确定终端(如远端设备或中继设备)的传输优先级,是当前亟需解决的问题。
图1A为一种中继场景的传输示意图,在图1A中远端设备可以通过中继设备与网络设备通信,示例性的,传输方法100包括:
S110:网络设备向远端终端指示传输资源,可选的,该传输资源为上行链路资源或者侧 行链路资源。容易理解的,S110为远端终端获取传输资源的一种方式,本申请实施例并不限定。
远端终端可以与中继终端之间进行侧行链路通信或者称为两者之间直连通信,也可以通过中继终端与网络设备进行通信,也就是说,远端终端可以具有多个业务待传输,例如与中继终端进行侧行通信相关的normal SL业务和/或与中继通信相关的relay SL业务,其中业务可以包括信令或数据,业务可以是与链路对应的。示例性的,在传输资源有限,或者存在多个传输业务待传输的情况下,方法100还包括:
S120:远端终端确定传输优先级。也就是说,远端终端确定将在步骤S110中获取的传输资源用于哪个传输业务。
一种可能的方式中,方法100包括:S130:远端终端传输relay SL业务,其中,relay SL具有较高的传输优先级。可以理解为,步骤S120中确定relay SL业务的优先级较高,传输资源优先用于传输relay SL业务。
又一种可能的方式中,方法100包括:S140:远端终端传输normal SL业务,其中,normal SL具有较高的传输优先级。可以理解为,步骤S120中确定normal SL业务的优先级较高,传输资源优先用于传输normal SL业务。
类似的,中继终端可以与远端终端之间进行侧行链路通信,也可以为远端终端通过通信服务,也就是说,远端终端也可以具有多个业务待传输,例如与远端终端进行侧行通信相关的normal SL业务、与中继通信相关的relay SL业务、或与网络设备通信相关的上行业务。
S150:网络设备向远端终端指示传输资源,可选的,该传输资源为上行链路资源或者侧行链路资源。
示例性的,在传输资源有限,或者存在多个传输业务待传输的情况下,方法100还包括:
S160:中继终端确定传输优先级。也就是说,中继终端确定将在步骤S150中获取的传输资源用于哪个传输业务。
一种可能的方式中,方法100包括:S170:中继终端传输relay SL业务,其中,relay SL具有较高的传输优先级。可以理解为,步骤S150中确定relay SL业务的优先级较高,传输资源优先用于传输relay SL业务。
又一种可能的方式中,方法100包括:S180:中继终端传输normal SL业务,其中,normal SL具有较高的传输优先级。可以理解为,步骤S150中确定normal SL业务的优先级较高,传输资源优先用于传输normal SL业务。
又一种可能的方式中,方法100包括:S190:中继终端传输上行业务,其中,上行业务具有较高的传输优先级。可以理解为,步骤S150中确定上行业务的优先级较高,传输资源优先用于传输上行业务。
容易理解的,步骤S110-S140可以与S150-S190耦合或解耦执行,本申请实施例并不限定。步骤之间也可以是耦合的,例如确定传输优先级的步骤可以与传输业务的步骤耦合,例如,步骤S150与步骤S170-S190耦合。
容易理解的,优先级确定对于传输资源的有效使用和传输效率的改善具有较大的影响,因此如何通过优化传输优先级确定的方法,提升通信传输效率是亟需解决的问题。
图2A为本申请实施例提供的一种传输的方法200,用于实现确定传输优先级,改善通信质量。该方法的执行主体可以是终端(例如中继终端或者远端终端),也可以是支持终端 实现该方法的芯片、芯片系统、或处理器等。为了便于介绍,在下文中,以该方法由终端执行为例,如图2A所示,该方法200可以包括如下步骤:
S210:获取侧行链路资源。
步骤S210可以理解为接收、发现,检测或请求用于传输侧行链路对应的业务的资源。可选的,获取的方式可以是通过消息或信令进行。
在一种可能的实施方式中,获取侧行链路资源可以具体实施为:接收来自网络设备的侧行链路资源。例如,该侧行链路资源为侧行链路授权(sidelink grant,SL grant)。
在另一种可能的实施方式中,获取侧行链路资源可以具体实施为:通过感知(sensing)竞争选择资源获取侧行链路资源。例如,该侧行链路资源为侧行链路授权。
S220:从N个目的地址中确定第一目的地址,该N个目的地址对应于从第一类型侧行链路和第二类型侧行链路中确定的一种类型链路;侧行链路资源用于进行第一目的地址对应的传输,其中,N为大于等于1的整数。
其中,N个目的地址(destination)对应于从第一类型侧行链路和第二类型侧行链路中确定的一种类型链路可以理解为,N个目的地址对应于从第一类型SL和第二类型SL中确定的第一类型SL或第二类型SL。可选的,确定可以称为选择、筛选或提取,本申请实施例并不限定。例如,当第一类型侧行链路的业务和第二类型侧行链路的业务都待传输时,从第一类型侧行链路和第二类型侧行链路中确定出一种类型的链路,从该一种类型的链路对应的N个目的地址中选择第一目的地址。示例性的,S220中的一种类型链路可以称为一个类型链路、一种链路、一类链路或者目标类型链路。
本申请实施例中,N个目的地址对应于一种类型链路(如第一类型SL)主要指该N个目的地址为该第一类型SL关联或对应的目的地址。例如,N个目的地址对应于relay SL,可以理解为是relay SL对应的N个目的地址,或者relay SL对应的目的地址,该目的地址可以是一个或多个。其中,relay SL对应的目的地址主要是指该目的地址对应的链路用来传输中继的业务(如数据、信令等)。
步骤S220可以理解为,从第一类型侧行链路和第二类型侧行链路中确定的一种类型链路对应的N个目的地址中确定(或选择)第一目的地址,使用侧行链路资源传输第一目的地址对应的业务。也就是说,为步骤S210中获取的SL传输资源从目标类型链路中选择或确定目的地址。可选的,在传输冲突或者传输资源有限时,在多个类型的侧行链路中确定与传输资源对应的类型的侧行链路,有利于使得不同类型的侧行链路的传输优先级的处理更加灵活,提升通信质量。
可选的,从第一类型侧行链路和第二类型侧行链路中确定的一种类型链路,其中,该一种类型链路满足条件或规则,可以理解的,该条件或规则包括有利于优先传输优先级的相关信息,例如该条件或规则包括优先级相关的条件,业务关联的条件,制式条件(例如,第一制式对应的链路优先于第二制式对应的链路)或具体场景的需求中的一种或多种。例如,工业侧行链路传输中,该条件可以优先考虑传输的时延需求。示例性的,以该一种类型链路满足优先级条件为例。也就是说,从第一类型侧行链路和第二类型侧行链路中确定满足优先级条件的一种类型链路,也可以称为,根据优先级条件从第一类型侧行链路和第二类型侧行链路中确定一种类型链路。
可选的,该优先级条件与SL对应的优先级信息有关,例如,该优先级条件与第一类型 SL对应的优先级信息和/或第二类型SL对应的优先级信息有关。容易理解的,SL对应的优先级信息包括但不限定,SL对应的逻辑信道关联的优先级,SL对应的媒体访问控制(media access control element,MAC CE)关联的优先级等。
一种可能的实现方式中,N个目的地址对应于从第一类型侧行链路和第二类型侧行链路中确定的一种类型链路包括:
N个目的地址对应于第一类型侧行链路,其中,第一类型侧行链路对应的优先级信息满足第一条件,或者,第一类型侧行链路对应的优先级信息不满足第一条件和第二类型对应的优先级信息不满足第二条件。
一种可能的实现方式中,N个目的地址对应于从第一类型侧行链路和第二类型侧行链路中确定的一种类型链路包括:
N个目的地址对应于第二类型侧行链路,其中,第一类型侧行链路对应的优先级信息不满足第一条件和第二类型对应的优先级信息满足第二条件。
示例性的,第一条件包括:第一类型侧行链路对应的至少一个目的地址中包括关联的优先级值小于第一阈值或者属于第一列表的目的地址。可选的,第一条件也可以理解为第一类型侧行链路对应的destination存在关联的LCH或者SL MAC CE对应的最小优先级值小于第一阈值或者属于第一列表。一种可能的实现方式中,第一条件中的小于阈值也可以是小于等于阈值。
示例性的,第二条件包括:第二类型侧行链路对应的至少一个目的地址中包括关联的优先级值小于第二阈值或者属于第二列表的目的地址。可选的,第二条件也可以理解为第二类型侧行链路对应的destination存在关联的LCH或者SL MAC CE对应的最小优先级值小于第二阈值或者属于第二列表。
可选的,关联的优先级值包括以下至少一项:关联的侧行逻辑信道对应的优先级值、关联的侧行媒体接入控制控制元素SL MAC CE对应的优先级值、关联的侧行逻辑信道对应的逻辑信道对应的优先级值、关联的侧行SL MAC CE关联的逻辑信道对应的优先级值。示例性的,关联的侧行逻辑信道对应的优先级值主要是指该类型SL对应的目的地址关联的侧行逻辑信道对应的优先级值。关联的SL MAC CE对应的优先级值主要是指该类型SL对应的目的地址关联的SL MAC CE对应的优先级值。容易理解的,在一些场景中(如终端到网络中继(UE to network relay)场景),一个侧行中继链路的逻辑信道会有相关联的逻辑信道(如上行逻辑信道(uplink logical channel,UL LCH))。目的地址所关联的SL LCH或者SL MAC CE的优先级值可以代替为目的地址所关联的SL LCH或者SL MAC CE所关联的UL LCH的优先级值。也就是说可以用SL LCH或者SL MAC CE关联的UL LCH的优先级值来进行优先级比较。容易理解的,优先级值可以指最小优先级值。优先级值与优先级有关联关系,优先级值小对应的优先级高,示例性的,A的优先级值为0.1,B的优先级值为0.2,则A的优先级高于B的优先级。典型的示例,最小优先级值可以表示最高优先级。
可选的,第一阈值、第二阈值、第一列表或者第二列表是网络设备配置的、预配置的或者预定义的。示例性的,第一阈值或第二阈值可以复用现有的阈值,或者是新定义的阈值。本申请不限定阈值的配置形式,第一阈值或第二阈值可以是列表的形式,例如,小于第一阈值可以代替为属于第一列表。可选的,第一阈值或第二阈值可以是目的地址级的配置(或者称为目的地址粒度的配置),当然,第一阈值或第二阈值也可以是链路类型级别的配置,本 申请实施例并不限定。示例性的,配置阈值或列表的消息或信令为高层消息,比如为广播消息,系统消息,接入过程中的下行消息,无线资源控制(radio resource control,RRC)信令,媒体访问控制(media access control element,MAC CE),或者物理层控制信令等。或者,该消息或信令还可以为物理层下行控制信息(downlink control information,DCI),等等,本申请不做限定。
一种可能的方式中,第一类型侧行链路为中继侧行链路,第二类型侧行链路为普通侧行链路。
示例性的,步骤S220的一种可能的实现方式中,
从第一类型侧行链路或第二类型侧行链路对应的N个目的地址中确定第一目的地址;侧行链路资源用于进行所述第一目的地址对应的传输;其中,第一类型侧行链路的业务和第二类型侧行链路的业务都待传输,N为大于等于1的整数。
其中,第一类型侧行链路的业务和第二类型侧行链路的业务都待传输可以理解为,存在第一类型侧行链路的业务和第二类型侧行链路的业务待传输。可选的,存在可以理解为在传输时刻或传输时间窗内存在,或者同时存在。
一种可能的方式中,从第一类型侧行链路或第二类型侧行链路对应的N个目的地址中确定第一目的地址包括:从第一类型侧行链路对应的N个目的地址中确定第一目的地址,其中,第一类型侧行链路对应的优先级信息满足第一条件,或者,第一类型侧行链路对应的优先级信息不满足第一条件和第二类型侧行链路对应的优先级信息不满足第二条件。
一种可能的方式中,从第一类型侧行链路或第二类型侧行链路对应的N个目的地址中确定第一目的地址包括:
从第二类型侧行链路对应的N个目的地址中确定第一目的地址,其中,第一类型侧行链路对应的优先级信息不满足第一条件和第二类型对应的优先级信息满足第二条件。
从N个目的地址中确定第一目的地址的一种可能的实现方式中,根据N个目的地址分别对应的优先级信息选择第一目的地址。示例性的,N个目的地址分别对应的优先级信息包括但不限定于目的地址对应的SL逻辑信道的优先级信息,和/或目的地址对应的SL MAC CE关联的优先级信息。一种可能的举例中,按照SL逻辑信道优先级确定第一目的地址,具体的,在单播、组播、广播关联的SL逻辑信道或者SL MAC CE中选择最高优先级同时满足附加条件的SL LCHs或SL MAC CE对应的目的地址(比如附加条件可以是:有有效的SL传输数据、SBj大于零、允许使用的资源类型信息(例如SL grant是configured grant type1)等)。容易理解的,在选择了第一目的地址之后,选择与第一目的地址关联的满足条件的SL逻辑信道,例如,该条件可以与以下信息相关:有有效的SL传输数据、允许使用的资源类型信息、和混合自动重传请求(hybrid automatic repeat request,HARQ)属性信息等。
容易理解的,为避免重复描述,该实现方式下第一条件和第二条件相关的描述可以参考步骤S220中的描述。
本申请实施例中,第一类型SL和第二类型SL可以理解为对SL分类或区分,本申请实施例并不限定对SL进行分类的方式,例如,可以按照该SL传输的业务的类型来分类,示例性的SL类型可以包括但不限于用于传输中继业务的relay SL和用于传输非中继业务(或者也可以称为正常侧行业务)的normal SL。当然,也可以按照其他的方式对SL进行分类,也可以包括除示例的这几种类型的SL之外的其他类型的侧行链路,本申请实施例并 不限定。
例如,当第一类型SL为relay SL,第二类型SL为normal SL时,N个目的地址对应于从relay SL和normal SL中确定的一种类型链路,也就是说,N个目的地址对应于从relay SL和normal SL中确定的relay SL,或者,N个目的地址对应于从relay SL和normal SL中确定的normal SL。一种示例中,当relay SL对应的传输优先级较高或者满足第一条件时,则优先传输relay SL对应的传输。在第一条件不满足时,再去判断normal SL对应的传输的优先级是否较高或者是否满足第二条件,也就是说,根据第一条件和/或第二条件可以优先传输relay SL对应的业务。
示例性的,使用侧行链路资源传输第一目的地址对应的业务可以理解为,为该侧行链路资源选择目的地址,或者,该侧行链路资源用于传输第一目的地址关联的逻辑信道对应的业务。
一种可能的方式中,步骤S220由远端终端执行时,步骤S220可以理解为图1B的步骤S120与S130-S140之间的耦合;又一种可能的方式中,步骤S220由中继终端执行时,步骤S220可以理解为图1B的步骤S160与S170-S180之间的耦合,步骤S220中具体优化了确定传输优先级的方法,改善了通信质量。
作为步骤S220的一种可选的实现方式,如图2B所示,S220包括:
S221:确定(或判断)第一条件是否满足,如果第一条件满足则从第一类型SL对应的N个目的地址中选择第一目的地址;如果第一条件不满足,执行步骤S222。
S222:确定第二条件是否满足,如果第二条件满足从第二类型SL对应的N个目的地址中选择第一目的地址;如果第二条件不满足,从第一类型SL对应的N个目的地址中选择第一目的地址。
容易理解的,关于第一条件和第二条件相关的介绍可以参考步骤S220中的相关描述,不再赘述。示例性的,第一条件可以是第一类型SL对应的destination存在关联的SL LCH或者SL MAC CE对应的最小优先级值小于第一阈值。第二条件可以是第二类型SL对应的destination存在关联的SL LCH或者SL MAC CE对应的最小优先级值小于第二阈值。本申请实施例中的条件(如第一条件)中的小于阈值可以替换为小于等于阈值。类似的,条件中的大于等于阈值可以替换为大于阈值。
通过步骤S220,可以确定获取的SL资源用来传输哪个类型的SL对应的业务,提升了通信质量。
一种可能的方式中,该方法适用于远端设备或者适用于中继设备,例如,该方法由远端终端执行,或者该方法由中继终端执行。
上述方法中,通过获取侧行传输资源,并在目的类型侧行链路中为该侧行传输资源选取目的地址,其中,可选的,可以根据条件或规则在多个侧行链路类型中选择目的类型侧行链路,可以使得优先传输目的类型侧行链路对应的传输,或者在满足一定条件时,优先从目的类型侧行链路对应的至少一个目的地址中进行目的地址的选择。上述方法还介绍了多维度的条件或规则,以及条件的组合方式用于灵活的实现传输资源对应哪种类型的侧行链路,例如,可以根据链路的传输业务类型,链路的传输需求和制式信息等信息为传输资源确定目的地址,提升通信质量。示例性的,考虑relay SL承载的Uu相关业务相比于normal SL承载的非中继业务的优先级需求可能较高,可以通过本申请实施例的方法优先传输relay SL对 应的传输,有利于提升中继的通信质量。
在一些场景中,需要考虑侧行链路和上行链路传输优先级的比较,图3为本申请实施例提供的一种传输的方法300,用于实现确定传输优先级。该方法的执行主体可以是终端(例如中继终端或者远端终端),也可以是支持终端实现该方法的芯片、芯片系统、或处理器等。为了便于介绍,在下文中,以该方法由终端执行为例,如图3所示,该方法300可以包括如下步骤:
S310:获取传输资源。

其中,侧行链路资源与上行链路资源存在重叠,侧行链路对应的优先级信息和上行链路对应的优先级信息满足第三条件。可选的,侧行链路资源与上行链路资源存在重叠可以理解为侧行链路对应的业务与上行链路对应的业务都待传输。

一种可能的实现中,侧行链路为中继侧行链路。
上述可能的方式中,通过判断第三条件是否满足,确定是否将传输资源用于上行链路。在侧行链路对应的优先级信息和上行链路对应的优先级信息都满足一定条件时,确定在传输资源上进行上行链路传输,在确定传输优先级时,增加了侧行链路传输的优先级信息的比重,提升了侧行链路通信的质量。特别的,在侧行链路是中继SL时,考虑relay SL承载上行链路承载和都可能是Uu相关业务,在UL传输和SL传输优先级比较中,同等考虑relay SL优先级和UL传输的优先级。
再一种可能的实现方式中,方法还包括S330:在传输资源上进行侧行链路传输。

上述可能的方式中,在确定传输优先级时,增加了侧行链路传输的优先级信息的比重,提升了侧行链路通信的质量。特别的,在侧行链路是中继SL时,考虑relay SL承载上行链路承载和都可能是终端与网络设备之间(如Uu)相关业务,在UL传输和SL传输优先级比较中,同等考虑relay SL优先级和UL传输的优先级,提升了中继的通信质量。
又一种可能的实现方式中,方法还包括S340:基于终端实现确定在传输资源上进行侧行链路传输或上行链路传输。
其中,侧行链路资源与上行链路资源存在重叠,侧行链路对应的优先级信息和上行链路对应的优先级信息满足第五条件。基于终端实现可以理解为,由终端确定或者由终端选择,也就是说,终端可以根据当前传输的相关信息灵活确定上行链路和侧行链路的传输优先级。

一种可能的方式中,方法300由中继终端执行时,步骤S320和S330可以理解为分别与图1B的步骤S180和S190对应,方法300中具体优化了确定传输优先级的方法,改善了通信质量。
上述可能的方式中,通过判断第五条件是否满足,在侧行链路对应的优先级信息和上行链路对应的优先级信息都满足一定条件时,基于终端的实现来确定上行链路或侧行链路使用传输资源。在确定传输优先级时,增加了侧行链路传输的优先级信息的比重,提升了侧行链路通信的质量。特别的,在侧行链路是中继SL时,考虑relay SL承载上行链路承载和都可能是Uu相关业务,在UL传输和SL传输优先级比较中,同等考虑relay SL优先级和UL传输的优先级。
