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，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
应理解，本申请实施例的技术方案可以应用于各种通信系统，例如：LTE sidelink系统、NR sidelink系统，或者后续演进通信系统。
在本申请实施例中，终端设备可以包括但不限于移动台(Mobile Station，MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment，UE)、手机(handset)及便携设备(portable equipment)、车辆(vehicle)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)、具有无线通信功能的计算机等，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。
本申请实施例中，网络设备是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。所述网络设备可以为基站，所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等。在采用不同的无线接入技术的系统中，具有基站功能的设备的名称可 能会有所不同。例如在LTE网络中，称为演进的节点B(Evolved NodeB，eNB或eNodeB)，在第三代(3rd Generation，3G)网络中，称为节点B(Node B)，在5G系统中称为下一代节点B(gNB)，或者后续演进通信系统中的网络设备等等，然用词并不构成限制。
如图1所示，本申请的一个实施例提供一种优先级确定方法100，该方法可以由终端设备执行，换言之，该方法可以由安装在终端设备的软件或硬件来执行，该方法包括如下步骤。
S102：确定第一消息的优先级，其中，所述第一消息包括中继终端或远端终端传输的消息。
S104：根据所述优先级进行所述第一消息的传输。
本申请实施例中，终端设备可以根据预设规则来确定第一消息的优先级，该预设规则可以由网络设备配置、协议约定或终端设备实现。可选地，S102之前，终端设备可以接收来自于网络设备的指示信息，该指示信息用于指示终端设备根据预设规则来确定第一消息的优先级。
本申请实施例通过S102确定出第一消息的优先级后，还可以与其它消息的优先级进行对比。这样，S104中提到的根据所述优先级进行所述第一消息的传输例如包括：在确定出第一消息的优先级高于其它消息的优先级的情况下，优先传输第一消息，后续再传输或直接丢弃其它消息；或者是，在确定出其它消息的优先级高于第一消息的优先级的情况下，优先传输其它消息，后续再传输或直接丢弃第一消息，或者是在当前资源不足的情况下，取消第一消息在当前资源的传输，通过后续调度的资源传输第一消息。
本申请实施例可以应用在副链路中继架构中，如图2和图3所示，图2和图3示出了两种典型副链路中继架构示意图。
在图2所示的副链路中继架构下，中继终端起到数据中转作用，可以将来自于远端终端的数据和信令转发给网络设备，还可以将来自于网络设备的数据和信令转发给远端终端。图2只是中继架构的简单示例，实际上，远端终端和网络设备之间的中继终端的数量还可以为多个。

需要说明是的是，本说明书各个实施例中提到的中继终端(relay UE)，一般是指作为远端终端与其他UE/网络设备通信的中继的UE，因此，还可以用其他的技术术语来描述中继终端，如中继，中继节点、中转节点等等。本说明书各个实施例中提到的远端终端(remote UE)，一般是指需要通过中继与其他UE/网络设备进行通信的UE，因此，还可以用其他的技术术语来描述远端终端，如远程终端，等等。
本申请各个实施例中提到的relay UE，可以指图2所示的UE-to-network relay，也可以扩展为图3所示的UE-to-UE relay。前者指relay UE一端连接remote UE一端连接网络设备，后者指relay UE两端都连接remote UE。
另外，本申请各个实施例中提到的relay UE和remote UE的名称可能用其他的术语来替代。原则上，remote UE指的是需要通过中继与其他UE/网络设备侧进行通信的UE；relay UE指的是作为remote UE与其他UE/基站通信的中继的UE。
还需要说明的是，本说明书各个实施例中提到的“第一消息”以及“消息”，具体可以包括业务数据和/或信令。
其中，副链路(sidelink，SL)上传输的信令可以包括以下至少之一：PC5-S消息；PC5-无线资源控制(Radio Resource Control，RRC)消息；SL媒体接入控制(Media Access Control，MAC)控制单元(Control Element，CE)，即SL MAC CE；物理副链路反馈信道(Physical  Sidelink Feedback Channel，PSFCH)消息；或其他可能在物理信道上传输的消息，如副链路控制信息(sidelink Control Information，SCI)，副链路同步信号块(Sidelink Synchronization Signal and PBCH block，SL-SSB)等。

本申请实施例的执行主体可以是副链路中继架构中的远端终端，还可以是中继终端。在执行主体是远端终端的情况下，第一消息是远端终端传输的消息；在执行主体是中继终端的情况下，第一消息是中继终端传输的消息。
在一个例子中，在执行主体是中继终端的情况下，第一消息是中继终端传输的消息，第一消息包括如下之一：
情况一：第一消息是中继终端通过上行链路(UpLink，UL)传输的，第一消息是中继终端为远端终端中转的消息。情况一适用于图2所示的中继架构下，中继终端可以将来自于远端终端的第一消息转发给网络设备。
情况二：第一消息是中继终端通过UL传输的，第一消息是中继终端自身的消息。情况二适用于图2所示的中继架构下，中继终端将自身的消息发送给网络设备。

在另一个例子中，在执行主体是远端终端的情况下，第一消息是远端终端传输的消息，第一消息包括如下之一：
情况五：第一消息是远端终端通过SL传输的，第一消息需要中继终端为该远端终端进行中转。
情况五不仅适用于图2所示的中继架构，同时还适用于图3所示的中继架构。在图2所示的中继架构下，远端终端可以通过SL将第一消息发送给中继终端，中继终端可以该第一消息转发给网络设备。在图3所示的中继架构下，远端终端通过SL将第一消息发送给中继终端，中继终端可以该第一消息转发给另一个远端终端。
情况六：第一消息是远端终端通过SL传输的，该第一消息不需要中继终端进行中转。

情况七：第一消息是远端终端通过UL传输的，第一消息是远端终端自身的消息。
情况七可以用于图2和图3所示的中继架构下，在图2和图3所示的中继架构下，远端终端还可以通过UL与网络设备进行第一消息的交互。

本申请实施例提供的优先级确定方法，中继终端或远端终端可以确定第一消息的优先级，并按照确定出的优先级进行第一消息的传输，避免第一消息的传输出现顺序混乱的问题，提升通信效率。
为详细说明实施例100中提到的第一消息的优先级的确定方法，以下将分情况一至情况七这七种情况，对第一消息的优先级的确定方法进行详细介绍。
情况一：
第一消息是中继终端通过上行链路(UpLink，UL)传输的，第一消息是中继终端为远端终端中转的消息，实施例100中提到的确定第一消息的优先级包括：根据如下至少之一确定第一消息的优先级：
1)固定值，其中，第一消息的优先级是该固定值。
该例子中，第一消息可以是中继终端为远端终端中转的业务数据或信令(发送给网络设备)，该例子可以将该第一消息的优先级设定为一个固定优先级，即固定值，该固定值可以由网络设备配置、对端UE配置或协议约定。一种可选的方式是，将该固定值设置为最大优先级或最小优先级的数值。另一种可选的方式是，可以将该类传输(即第一消息)在特定的数据承载上来进行传输，对于此特定的数据承载，由协议约定一个固定的优先级。
2)第一消息对应的服务质量(Quality of Service，QoS)参数。
该例子中，第一消息可以是中继终端为远端终端进行中转的业务数据(发送给网络设备)，该业务数据的优先级基于该业务数据对应的QoS参数确定。
该QoS参数例如包括：PC5服务质量流标识(PC5 QoS Flow Identifier，PFI)，PC5服务质量标识(PC5 QoS Identifier，PQI)，PQI中的默认优先级等级(Default Priority Level)、优先级等级(priority level)，应用层指示的优先级(priority)等。例如，第一消息的优先级直接等于PFI或PQI或Default Priority Level或priority level；可选的，该第一消息的优先级，由该第一消息对应的QoS参数进行映射后得到的一个优先级确定，例如，PQI＝x，映射后的优先级为1，PQI＝y时，映射后的优先级为3；又例如，应用层指示的优先级(priority)较高的，映射后的优先级也较高。
3)在sidelink上传输第一消息的逻辑信道的优先级。
该例子中，第一消息可以是中继终端为远端终端中转的业务数据或信令(发送给网络设备)，第一消息的优先级可以基于sidelink上传输该业务数据的逻辑信道的优先级确定。例如，中继终端收到远端终端的第一消息后，将第一消息中的逻辑信道的优先级(或者是进行映射处理后得到的优先级)作为：①后续UL传输该第一消息时的优先级，或者②和其他消息的优先级或优先级相关门限进行对比时使用的优先级。
可选地，当该业务数据所在的MAC协议数据单元(Protocol Data Unit，PDU)中有多个逻辑信道时，该第一消息的优先级由这多个逻辑信道中最高的优先级所确定。例如，该第一消息的优先级等于上述最高的优先级，或者是，该第一消息的优先级根据上述最高的优先级进行映射处理后得到。
4)副链路控制信息(sidelink Control Information，SCI)中指示的优先级，该SCI来自于上述远端终端。
该例子中，第一消息可以是中继终端为远端终端中转的业务数据或信令(发送给网络设备)，第一消息的优先级可以基于sidelink上传输该业务数据时(由remote UE到relay UE) SCI中指示的优先级确定。例如，中继终端收到远端终端的第一消息后，(1)第一消息的优先级直接等于SCI中指示的优先级；或者是(2)第一消息的优先级是对SCI中指示的优先级进行映射处理后得到的优先级。
5)远端终端的标识。
该例子中，第一消息可以是中继终端为远端终端中转的业务数据或信令(发送给网络设备)，第一消息的优先级可以基于remote UE的标识来确定。例如，remote UE ID＝A时，第一消息的优先级为1；remote UE ID＝B,C,D时，第一消息的优先级为8。
6)在第一消息是远端终端的紧急(emergency)包数据网络(Packet Data Network，PDN)连接(connection)上的传输的情况下，第一消息的优先级最高。
该例子中，第一消息可以是中继终端为remote UE进行中转的业务数据，且对应的是Remote UE的emergency PDN connection上的传输，那么该传输(即第一消息)始终优先，即，默认优先级为最高。
7)触发第一消息的逻辑信道的优先级，第一消息是SR。
该例子中，第一消息可以是中继终端为remote UE进行中转的业务数据所触发的SR，那么该SR的优先级基于触发该SR的逻辑信道的优先级确定。例如，第一消息的优先级等于触发该第一消息的逻辑信道的优先级。
8)触发第一消息的逻辑信道的优先级，第一消息是缓存状态报告BSR。
该例子中，第一消息可以是中继终端为remote UE进行中转的业务数据所触发的BSR，那么该第一消息的优先级基于触发该BSR的逻辑信道的优先级确定。例如，第一消息的优先级等于触发该第一消息的逻辑信道的优先级。
9)中转第一消息时的QoS预算。
该例子中，第一消息可以是中继终端为remote UE进行中转的业务数据(发送给网络设备)，该传输(即第一消息)的优先级基于中转第一消息时的QoS预算来确定。例如，QoS预算处于第一取值区间内时，优先级为1，QoS预算处于第二取值区间内时，优先级为8。
该例子中提到的QoS预算可以为每一跳进行保证时，例如，整体要求QoS的时延为10ms，当第一消息从远端终端到中继终端时花费6ms，那么，中转时的QoS预算就是4ms。或者，一开始就规定整体时延和每一部分的时延，那么规定从中继终端到网络设备侧的时延为5ms，那么中转第一消息时的QoS预算就是5ms。
10)中转第一消息时的跳数。
该例子中，第一消息可以是中继终端为remote UE进行中转的业务数据或信令(发送给网络设备)，该传输(即第一消息)的优先级基于中转时的跳数来决定。例如，第一消息从远端终端经过了两个中继终端后到达目前的中继终端，跳数可以为2或者3(具体取决于已中转的中继终端的个数计算或者是以传输路径数量计算)；又例如，第一消息从远端经过了3个中继终端后到达目前的中继终端，跳数为3或者4。
该例子例如，跳数为2时，第一消息的优先级为6；跳数为3时，第一消息的优先级为4；跳数为4时，第一消息的优先级为1等等。
需要说明的是，上述1)至10)提到的根据如下至少之一(后文用XXX代替，XXX可以是上述1)至10)中的之一)确定第一消息的优先级，可以代表该优先级等于XXX，也可以代表该优先级与XXX有一定的映射关系，由XXX经过某种映射而来，该映射关系可以由协议约定、网络设备配置或对端UE配置或UE实现等。
具体例如，对于QoS参数(如PFI，PQI，PQI中的Default Priority Level、priority level，应用层指示的priority等)或者逻辑信道优先级或固定值或SCI中指示的优先级，这一类参数本身有优先级的含义，那么基于这些参数来确定第一消息的优先级，可能就直接等于 这些参数对应的优先级，如优先级值＝PQI、优先级值＝逻辑信道优先级等。
另外，对于上述1)至10)列出的这些子项，除了优先级可以直接等于的，还可以基于所有这些子项进行映射后得到新的优先级，如逻辑信道优先级高的，映射到高的优先级；远端终端标识为特定终端标识时，映射到高的优先级或低的优先级；中转时的QoS预算要求更高的，映射到更高的优先级；中转时的跳数更大的，映射到更高的优先级等等。
还需要说明的是，本申请实施例还可以根据上述1)至10)的至少两者确定第一消息的优先级，例如，基于1)中的固定值以及2)中的QoS参数进行映射处理后得到第一消息的优先级等等。
情况二
第一消息是中继终端通过UL传输的，第一消息是中继终端自身的消息，实施例100中提到的确定第一消息的优先级包括如下之一：
1)根据传输第一消息的逻辑信道的优先级，确定第一消息的优先级。
在第一消息是业务数据的情况下，第一消息的优先级可以基于传输该业务数据的逻辑信道的优先级确定。当该业务数据所在的MAC PDU中有多个逻辑信道时，第一消息的优先级由这多个逻辑信道中最高的优先级所确定。例如，该第一消息的优先级等于上述最高的优先级，或者是，该第一消息的优先级根据上述最高的优先级进行映射处理后得到。
2)根据第一消息对应的QoS参数，确定第一消息的优先级。
在第一消息是业务数据的情况下，第一消息的优先级可以基于该业务数据对应的QoS参数确定，如QFI(这里对应的是UL上的业务的QoS参数，和SL上的名称不同)，5QI，5QI中的Default Priority Level、priority level，应用层指示的priority等；例如，第一消息的优先级直接等于QFI或5QI或Default Priority Level或priority level；可选的，该第一消息的优先级，由该第一消息对应的QoS参数进行映射后得到的一个优先级确定，例如，5PQI＝x，映射后的优先级为1，5QI＝y时，映射后的优先级为3；又例如，应用层指示的优先级(priority)较高的，映射后的优先级也较高。
3)根据协议约定、网络设备配置或对端终端配置，确定第一消息的优先级。
在第一消息是信令的情况下，如MAC CE或SRB上的消息，第一消息的优先级可以由协议约定、网络设备配置或对端UE配置。
情况三
基于图2和图3所示的两种不同架构，情况三又可以分为两种不同的子情况，以下称作是子情况3.1和子情况3.2。
子情况3.1
第一消息是中继终端通过SL传输的，第一消息是中继终端为远端终端中转的消息，例如，在图2中，中继终端将来自于网络设备的第一消息转发给远端终端。这样，实施例100提到的确定第一消息的优先级包括：根据如下至少之一确定第一消息的优先级：
1)固定值，第一消息的优先级是该固定值。
该例子中，第一消息可以是中继终端为远端终端中转的业务数据或信令，该例子可以将该第一消息的优先级设定为一个固定优先级，即固定值，该固定值可以由网络设备配置、对端UE配置或协议约定。一种可选的方式是，将该固定值设置为最大优先级或最小优先级的数值。另一种可选的方式是，可以将该类传输(即第一消息)在特定的数据承载上来进行传输，对于此特定的数据承载，由协议约定一个固定的优先级。
2)第一消息对应的QoS参数。
该例子中，第一消息可以是中继终端为远端终端进行中转的业务数据，该业务数据的优先级基于该业务数据对应的QoS参数确定，
该QoS参数例如包括：PFI，PQI，PQI中的默认优先级等级(Default Priority Level)、 优先级等级(priority level)，应用层指示的优先级(priority)等。例如，第一消息的优先级直接等于PFI或PQI或Default Priority Level或priority level；可选的，该第一消息的优先级，由该第一消息对应的QoS参数进行映射后得到的一个优先级确定，例如，PQI＝x，映射后的优先级为1，PQI＝y时，映射后的优先级为3；又例如，应用层指示的优先级(priority)较高的，映射后的优先级也较高。
3)在副链路上传输第一消息的逻辑信道的优先级。
该例子中，第一消息可以是中继终端为远端终端中转的业务数据或信令，第一消息的优先级可以基于sidelink上传输该业务数据的逻辑信道的优先级确定。例如，中继终端收到来自于网络设备的第一消息后，将第一消息中的逻辑信道的优先级(或者是进行映射处理后得到的优先级)作为：①后续SL传输该第一消息时的优先级，或者②和其他消息的优先级或优先级相关门限进行对比时使用的优先级。
可选地，当该业务数据所在的MAC协议数据单元(Protocol Data Unit，PDU)中有多个逻辑信道时，该第一消息的优先级由这多个逻辑信道中最高的优先级所确定。例如，该第一消息的优先级等于上述最高的优先级，或者是，该第一消息的优先级根据上述最高的优先级进行映射处理后得到。
4)中转第一消息时的QoS预算。
该例子中，第一消息可以是中继终端为remote UE进行中转的业务数据，该传输(即第一消息)的优先级基于中转第一消息时的QoS预算来确定。例如，QoS预算处于第一取值区间内时，优先级为1，QoS预算处于第二取值区间内时，优先级为8。
该例子中提到的QoS预算可以为每一跳进行保证时，例如，整体要求QoS的时延为10ms，当第一消息从网络设备到中继终端时花费6ms，那么，中转时的QoS预算就是4ms。或者，一开始就规定整体时延和每一部分的时延，那么规定从中继终端到远端终端侧的时延为5ms，那么中转第一消息时的QoS预算就是5ms。
5)SCI中指示的优先级，该SCI来自于所述远端终端。
该例子中，第一消息可以是中继终端为远端终端中转的业务数据或信令，第一消息的优先级可以基于sidelink上传输该业务数据时(由remote UE到relay UE)SCI中指示的优先级确定。例如，(1)第一消息的优先级直接等于SCI中指示的优先级，或者是，(2)第一消息的优先级是对SCI中指示的优先级进行映射处理后得到的优先级。
需要说明的是，子情况3.1虽然是中继终端向远端终端传输第一消息，例如业务数据，在此之前，远端终端很可能也向中继终端传输过具有相似QoS需求的业务数据，远端终端可以通过SCI向中继终端指示这类具有相似QoS需求的业务数据的优先级。
