下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述，显然，所描述的实施例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术语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，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。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。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系 统包括终端11和网络侧设备12。其中，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装、游戏机等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网设备，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(Evolved Node B，eNB)、家用B节点、家用演进型B节点、无线局域网(Wireless Local Area Network，WLAN)接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
为了方便理解，以下对本申请实施例涉及的一些内容进行说明：
一、SL介绍
LTE系统支持SL，用于终端之间不通过网络侧设备进行直接数据传输。SL链路接口又可以称作PC5接口。
LTE sidelink的设计适用于特定的公共安全事务(如火灾场所或地震等灾难场所进行紧急通讯)或车联网(vehicle to everything，V2X)通信等。车联网通信包括各种业务，例如，基本安全类通信，高级(自动)驾驶，编队以及传感器扩展等等。由于LTE sidelink只支持广播通信，因此主要用于基本安全类通信，其他在时延、可靠性等方面具有严格服务质量(Quality of Service， QoS)需求的高级V2X业务将通过NR sidelink支持。
5G NR系统可用于LTE所不支持的6GHz以上工作频段，支持更大的工作带宽，目前NR sidelink传输除了支持广播(broadcast)，还可以支持组播(groupcast)和单播(unicast)的传输形式。单播顾名思义就是一对一(one to one)的传输。组播为一对多(one to many)的传输。广播也是one to many的传输，但是广播并没有UE属于同一个组的概念。
相较于LTE/NR Sidelink广播通信，NR Sidelink单播和组播通信引入支持了物理层混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)反馈机制。
二、资源分配模式
Sidelink UE的资源分配模式总共分为两类：
1、基站调度模式(Mode 1)：基站调度SL资源以供UE用于SL传输，由网络侧设备(基站)控制并为每个UE分配资源。
2、终端自主模式(Mode 2)：终端确定，即基站不调度由基站/网络侧设备配置的SL资源或预配置的SL资源内的SL传输资源，由每个终端自主选择资源。
三、非授权频段NR
在未来通信系统中，非授权频段(Unlicensed Band)可以作为授权频段(Licensed Band)的补充帮助运营商对服务进行扩容。为了与NR部署保持一致并尽可能的最大化基于NR的非授权接入，非授权频段可以工作在5GHz，37GHz和60GHz频段。由于非授权频段由多种无线接入技术(radio access technology，RAT)共用，例如WiFi，雷达，LTE辅助授权接入(LTE-Licensed-assisted Access，LTE-LAA)等，因此在某些国家或者区域，非授权频段在使用时必须符合规范以保证所有设备可以公平的使用该资源，例如先听后说(Listen Before Talk，LBT)，最大信道占用时间(Maximum Channel Occupancy Time，MCOT)等规则。
四、LBT
工作于非授权的频段的发送端在发送信号之前需要监听该频带(可以由中心频点+带宽标识)是否被占用，如果没有被占用，则发送端可以在该频带 进行信号的发送。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的SL业务传输处理方法进行详细地说明。
请参见图2，图2是本申请实施例提供的一种SL业务传输处理方法的流程图，如图2所示，包括以下步骤：
步骤201，终端根据SL业务对应的传输信息确定至少一个载波；
本申请实施例中，上述SL业务可以理解为待传输的业务，例如，UE上层有SL业务达到，上层提供了所述SL业务对应的传输信息，从而可以根据上层提供的传输信息确定至少一个载波。其中上层可以称之为upper layers，例如，接入层(Access Stratum layer)以上统称为上层。
应理解，上述SL业务可以理解一个新的SL业务，也可以理解为一个重新传输的SL业务。
步骤202，所述终端根据所述至少一个载波中的可用载波确定候选载波；
其中，所述至少一个载波包括第一载波和/或第二载波，所述第一载波为非授权频段的SL载波，所述第二载波为授权频段的SL载波。
本申请实施例中，上述非授权频段可以理解为unlicensed spectrum，也可以称之为共享频段。与wifi类似的短距离无线传输频段。上述第一载波还可以包括或者替换为智能交通运输频段(Intelligent transportation spectrum)。
本申请实施例通过终端根据SL业务对应的传输信息确定至少一个载波；所述终端根据所述至少一个载波中的可用载波确定候选载波；其中，所述至少一个载波包括第一载波和/或第二载波，所述第一载波为非授权频段的SL载波，所述第二载波为授权频段的SL载波。这样，由于明确了针对非授权频段的SL载波和授权频段的SL载波的波束选择机制，从而可以使得终端可以在合适的载波进行通信，保证通信性能。
可选地，在一些实施例中，所述传输信息包括载波列表和传输模式中的至少一项。
本申请实施例中，上述载波列表可以包括至少一个载波频点，上述传输模式可以理解或者替换为传输类型或传输格式。其中，传输模式可以包括授权频段的旁链路传输和非授权频段的旁链路传输中的至少一项。
可选地，所述传输模式满足以下至少一项：
不同的传输模式通过终端上层提供的发送配置(TX profile)携带；
不同的传输模式与至少一个载波频点关联；
不同的传输模式与至少一个业务类型关联；
不同的传输模式与至少一个应用标识关联；
不同的传输模式与至少一个目的层二标识(Destination L2 ID)关联；
不同的传输模式与至少一套服务质量参数关联。
本申请实施中，不同的传输模式与至少一个载波频点关联可以理解为包括以下至少一项关联关系：
一种传输模式与一个频点载波关联；
一种传输模式与至少两个频点载波关联；
至少两种传输模式与一个频点载波关联。
此外，对于传输模式与业务类型、应用标识、目的层二标识和服务质量参数之间的关联关系与上述传输模式与载波频点关联关系类似，具体可以参照传输模式与载波频点关联关系的描述，在此不再赘述。
应理解，业务类型或应用标识是上层概念，SL业务在上层通过不同的业务类型(service type)或应用标识(application identifier)来区分。目的层二标识是接入层的概念，SL业务在接入层通过不同的Destination L2 ID来表征。上述服务质量参数可以包括时延、可靠性和优先级等一个或多个维度的QoS参数。换句话说，服务质量参数可以是某个维度的QoS参数，也可以是多个维度的QoS参数组合。
需要说明的是，上述可用载波可以为至少一个载波中的部分或全部载波，例如，可用载波可以包括以下至少一项：N1个第一载波，N2个第二载波。在不同的场景下，对应的确定候选载波的方式不同，以下对此进行详细说明。
在一些实施例中，在所述可用载波为N1个第一载波的情况下，所述终端根据所述至少一个载波中的可用载波确定候选载波包括：
所述终端确定目标阈值；
所述终端将所述N1个第一载波中信道占用时间大于或等于所述目标阈值的第一载波确定为候选载波；
其中，N1为正整数。
可选地，本申请实施例中，所述终端确定目标阈值包括：
所述终端获取至少一个信道占用时间阈值(COT_Thres)，每个信道占用时间阈值对应至少一个SL逻辑信道优先级值；
所述终端将目标逻辑信道的SL逻辑信道优先级值对应的信道占用时间阈值确定为所述目标阈值，所述目标逻辑信道由所述SL业务对应的SL逻辑信道确定。
应理解，上述至少一个信道占用时间阈值可以为控制节点配置或预配置的，例如可以包括2ms和8ms等不同的阈值。上述SL逻辑信道优先级值越大表示对应的优先级越高，或者SL逻辑信道优先级值越小表示对应的优先级越低。其中，控制节点可以为网络侧设备或者终端，在此不做进一步的限定。
可选地，在一些实施例中，在所述可用载波为N1个第一载波的情况下，所述终端根据所述至少一个载波中的可用载波确定候选载波包括：
所述终端确定目标阈值；
所述终端将所述N1个第一载波中先听后说LBT成功率大于或等于所述目标阈值的第一载波确定为候选载波；
其中，N1为正整数。
应理解，LBT成功率的计算定义为(成功的LBT次数除以总LBT次数)；进一步的，还可以限定计算的时间窗，例如从当前时刻回溯到过去的1s内；或者从第一次LBT开始到当前时刻等等
可选地，本申请实施例中，所述终端确定目标阈值包括：
所述终端获取至少一个LBT阈值，每个LBT阈值对应至少一个SL逻辑信道优先级值；
所述终端将目标逻辑信道的SL逻辑信道优先级值对应的LBT阈值确定为所述目标阈值，所述目标逻辑信道由所述SL业务对应的SL逻辑信道确定。
需要说明的是，在一些实施例中，所述目标逻辑信道满足以下任一项：
所述目标逻辑信道为所述SL业务对应的所有SL逻辑信道中SL逻辑信道优先级最高的SL逻辑信道；
所述目标逻辑信道为M个SL逻辑信道中SL逻辑信道优先级最高的SL 逻辑信道，所述M为正整数，所述M个SL逻辑信道为所述SL业务对应的所有SL逻辑信道中仅用于非授权频段的SL逻辑信道。
应理解，本申请实施例中，目标逻辑信道为所述SL业务对应的所有SL逻辑信道中SL逻辑信道优先级最高的SL逻辑信道可以理解为：目标逻辑信道的确定不基于SL逻辑信道限制信息确定。所述目标逻辑信道为M个SL逻辑信道中SL逻辑信道优先级最高的SL逻辑信道可以理解为：目标逻辑信道的确定基于SL逻辑信道限制信息确定。该SL逻辑信道限制信息可以由控制节点配置或预配置。
进一步的，在一些实施例中，所述方法还包括：
所述终端基于控制节点配置或预配置的目标配置信息确定SL逻辑信道的类型，所述SL逻辑信道的类型包括仅用于非授权频段的SL逻辑信道和仅用于授权频段的SL逻辑信道中的至少一项。
其中，仅用于非授权频段可以表示为SL-U only，仅用于授权频段可以表示为SL only。
可选地，在一些实施例中，所述可用载波为所述至少一个载波中被包含在控制节点配置或预配置的SL资源的载波。
本申请实施例中，至少一个第一载波的部分或所有第一载波被包含在配置或预配置的SL资源中，则将所述被包含的部分或所有第一载波确定为可用的至少一个第一载波，即N1个第一载波。至少一个第二载波的部分或所有第二载波被包含在配置或预配置的SL资源中，则将所述被包含的部分或所有第二载波确定为可用的至少一个第二载波，即N2个第二载波。
可选地，在所述可用载波包括N1个第一载波和N2个第二载波的情况下，所述终端根据所述至少一个载波中的可用载波确定候选载波包括以下至少一项：
在所述终端不支持所述第一载波和所述第二载波同时工作的情况下，所述终端按照预设规则确定所述候选载波；
在所述终端支持所述第一载波和所述第二载波同时工作，所述终端将所述N1个第一载波和所述N2个第二载波确定为候选载波；
其中，N1和N2均为正整数。
本申请实施例中，中终端支持或者不支持所述第一载波和所述第二载波同时工作可以理解为终端的能力是否支持第一载波和第二载波同时工作，或者控制节点根据通信的场景确定是否支持第一载波和第二载波同时工作，或者控制节点指示终端是否支持第一载波和第二载波同时工作。
应理解，当可用载波仅包括N2个第二载波的情况下，可以参照相关技术确定候选载波，在此不再赘述。
可选地，在一些实施例中，所述预设规则包括以下至少一项：
规则1，根据控制节点发送的指示信息确定基于所述N1个第一载波或者所述N2个第二载波选择候选载波；
规则2，协议约定优先第一载波或第二载波的情况下，确定基于目标对象选择候选载波，在优先第一载波的情况下，目标对象为所述N1个第一载波，在优先第二载波的情况下，所述目标对象为所述N2个第二载波；
规则3，在所述N1个第一载波中的所有第一载波的测量结果均不满足第一测量条件的情况下，确定基于所述N2个第二载波选择候选载波；
规则4，所述SL业务对应的SL逻辑信道中第一逻辑信道的优先级高于或等于所述SL业务对应的SL逻辑信道中第二逻辑信道的优先级的情况下，确定基于所述N1个第一载波选择候选载波；
规则5，在第一目标载波的测量结果大于或等于第一预设值，且第二目标载波的测量结果小于或等于第二预设值的情况下，确定基于所述N1个第一载波选择候选载波，否则确定基于所述N2个第二载波选择候选载波；
规则6，在所述N2个第二载波中所有第二载波的测量结果均不满足第二测量条件的情况下，确定基于所述N1个第一载波选择候选载波；
规则7，所述SL业务对应的SL逻辑信道中第一逻辑信道的优先级高于或等于所述SL业务对应的SL逻辑信道中第二逻辑信道的优先级的情况下，确定基于所述N2个第二载波选择候选载波；
规则8，在第一目标载波的测量结果小于或等于第三预设值，且第二目标载波的测量结果大于或等于第四预设值的情况下，基于所述N2个第二载波选择候选载波，否则基于所述N1个第一载波选择候选载波；
其中，所述第一目标载波为所述N1个第一载波中测量结果最好的载波， 所述第二目标载波为所述N2个第二载波中测量结果最好的载波，所述第一逻辑信道为仅用于非授权频段的所有逻辑信道中优先级最高的逻辑信道，所述第二逻辑信道为仅用于授权频段的所有逻辑信道中优先级最高的逻辑信道。
本申请实施例中，测量结果通常包括一个或者多个维度的测量结果，例如可以包括信道忙碌比率(Channel Busy Rate，CBR)和旁链路参考信号接收功率(Sidelink Reference Signal Received Power，SL-RSRP)。其中，测量结果最好可以理解为某一维度的测量结果最好，例如，针对CBR，CBR的值越小越好；针对SL-RSRP，SL-RSRP的值越大越好。
针对规则1，如果指示信息指示了第一载波，则N1个第一载波可以纳入候选载波。如果指示信息指示了第二载波，则N2个第二载波可以纳入候选载波
针对规则2，可以理解为总是目标对象优先，例如，如果协议规定了第一载波优先，则N1个第一载波可以纳入候选载波；协议规定了第二载波优先，则N1个第二载波可以纳入候选载波。
可选地，上述规则4和规则7同时存在的情况下，针对所述SL业务对应的SL逻辑信道中第一逻辑信道的优先级等于所述SL业务对应的SL逻辑信道中第二逻辑信道的优先级的情况，可以基于所述N1个第一载波选择候选载波，也可以基于所述N2个第二载波选择候选载波。即规则4和规则7中仅一个规则中保留等于的情况。
需要说明的是，上述规则1至规则8仅说明了优先选择基于第一载波确定候选载波还是优先基于第二载波选择候选载波。进一步地，在确定基于第一载波或第二载波选择候选载波后，进一步地，针对具体选择候选载波的方式可以根据实际需要进行设置。例如，在一些实施例中，所述预设规则还包括以下至少一项：
若基于所述N1个第一载波选择候选载波，则在所述N1个第一载波中的至少一个第一载波的测量结果满足第一测量条件的情况下，确定测量结果满足所述第一测量条件的第一载波为候选载波；
若基于所述N2个第二载波选择候选载波，则在所述N2个第一载波中的至少一个第二载波的测量结果满足第二测量条件的情况下，确定测量结果满 足所述第二测量条件的第二载波为候选载波。
本申请实施例中，上述第一测量条件可以理解为第一载波的测量结果大于或小于某一预设阈值，上述第二测量条件可以理解为第二载波的测量结果大于或小于某一预设阈值。具体地，预设阈值的大小可以根据实际情况进行设置，在此不做进一步的限定。由于选择满足第一测量条件的第一载波或者满足第二测量条件的第二载波作为候选载波，从而可以提高传输的可靠性。
可选地，在所述终端支持所述第一载波和所述第二载波同时工作，且所述第一载波上授权的第一资源与所述第二载波上授权的第二资源在时域发生重叠的情况下，所述终端的传输行为满足以下任一项：
所述第一资源优先或所述第二资源优先；
基于至少一个第三逻辑信道的SL逻辑信道优先级与至少一个第四逻辑信道的SL逻辑信道优先级确定所述第一资源优先或所述第二资源优先；
其中，所述至少一个第三逻辑信道包括所述SL业务中与仅用于非授权频段的SL逻辑信道；所述至少一个第四逻辑信道包括所述SL业务中与仅用于授权频段的SL逻辑信道。
可选地，基于至少一个第三逻辑信道的SL逻辑信道优先级与至少一个第四逻辑信道的SL逻辑信道优先级确定所述第一资源优先或所述第二资源优先包括以下至少一项：
在所述至少一个第三逻辑信道的最高SL逻辑信道优先级高于或等于所述至少一个第四逻辑信道的最高SL逻辑信道优先级的情况下，所述第一资源优先；
在所述至少一个第四逻辑信道的最高SL逻辑信道优先级高于或等于所述至少一个第三逻辑信道的最高SL逻辑信道优先级的情况下，所述第二资源优先。
可选地，针对所述至少一个第四逻辑信道的最高SL逻辑信道优先级等于所述至少一个第三逻辑信道的最高SL逻辑信道优先级的情况，可以是第一资源优先，也可以是第二资源优先。也就是说，在同时包括以上两项时，基于至少一个第三逻辑信道的SL逻辑信道优先级与至少一个第四逻辑信道的SL逻辑信道优先级确定所述第一资源优先或所述第二资源优先包括：
在所述至少一个第三逻辑信道的最高SL逻辑信道优先级高于或等于所述至少一个第四逻辑信道的最高SL逻辑信道优先级的情况下，所述第一资源优先；
在所述至少一个第四逻辑信道的最高SL逻辑信道优先级高于所述至少一个第三逻辑信道的最高SL逻辑信道优先级的情况下，所述第二资源优先。
或者，基于至少一个第三逻辑信道的SL逻辑信道优先级与至少一个第四逻辑信道的SL逻辑信道优先级确定所述第一资源优先或所述第二资源优先包括：
在所述至少一个第三逻辑信道的最高SL逻辑信道优先级高于所述至少一个第四逻辑信道的最高SL逻辑信道优先级的情况下，所述第一资源优先；
在所述至少一个第四逻辑信道的最高SL逻辑信道优先级高于或等于所述至少一个第三逻辑信道的最高SL逻辑信道优先级的情况下，所述第二资源优先。
可选地，所述终端的传输行为还满足以下至少一项：
在所述第一资源优先的情况下，执行第一操作，所述第一操作包括以下至少一项：选择所述至少一个第三逻辑信道执行逻辑信道优先(Logical channel priority，LCP)流程；丢弃所述第二资源；
在所述第二资源优先的情况下，执行第二操作，所述第二操作包括以下至少一项：选择所述至少一个第四逻辑信道执行逻辑信道优先LCP流程，丢弃所述第一资源。
本申请实施例中，选择所述至少一个第三逻辑信道执行LCP流程可以理解为：选择至少一个第三逻辑信道复用发送SL媒体接入控制(Media Access Control，MAC)协议数据单元(Protocol Data Unit，PDU)；选择所述至少一个第三逻辑信道执行LCP流程可以理解为：选择至少一个第四逻辑信道复用发送SL MAC PDU。
可选地，在一些实施例中，若所述终端的资源分配模式为终端自主选择模式，所述终端的传输行为还满足：
在丢弃所述第一资源的情况下，触发第一资源重选；
在丢弃所述第二资源的情况下，触发第二资源重选。
本申请实施例中，由于在丢弃相应的资源后，再次触发相应的资源重选，从而可以提高传输的可靠性。
为了更好的理解本申请，以下同一些具体实例进行详细说明。
实施例一：仅有至少一个第一载波的多载波场景。
步骤1，UE上层有SL业务到达，上层提供了所述SL业务对应的传输信息。该传输信息包括以下至少一项：
载波列表，所述载波列表包括至少一个载波频点；
传输模式，也可以称之为传输类型或传输格式。
其中，传输模式包括授权频段的旁链路传输(也可以称之为SL-U模式)和非授权频段的旁链路传输(也可以称之为SL模式)中的至少一项。
可选地，不同的传输模式满足以下至少一项：
不同的传输模式通过终端上层提供的发送配置(TX profile)携带；
不同的传输模式与至少一个载波频点关联；
不同的传输模式与至少一个业务类型关联；
不同的传输模式与至少一个应用标识关联；
不同的传输模式与至少一个目的层二标识关联；
不同的传输模式与至少一套服务质量参数关联。
步骤2：若根据步骤1的传输信息确定的是“至少一个第一载波”，且“至少一个第一载波”的部分或所有第一载波被包含在基站配置或预配置的SL资源中，则将所述被包含的部分或所有第一载波确定为“可用的至少一个第一载波”。
可选地，终端可以根据以下规则至少之一确定候选载波：
规则A：结合A-1和A-2，UE确定唯一的COT_Thres(k)。如果“可用的至少一个第一载波”中某一个载波的COT大于或等于COT_Thres(k)，则将相应载波纳入候选载波。
A-1：UE获取基站配置或预配置的一个或多个COT_Thres(1,2,3,...k,...N)，其中每个COT_Thres(k)关联一个或多个SL逻辑信道优先级值Priority(1,2,3,...j,...8)。
A-2：UE确定其中最高的SL逻辑信道优先级值，包括以下方法之一：
根据所述SL业务对应的所有SL逻辑信道中取其中最高优先级值；
UE获取基站配置或预配置的SL逻辑信道限制信息，根据所述SL业务对应的所有SL逻辑信道中，先选出其中SL逻辑信道限制为“SL-U only”的逻辑信道，取其中最高优先级值。一个特例，假设此时先选出其中SL逻辑信道限制为“SL-U only”的逻辑信道为0个，则意味着“可用的至少一个第一载波”均不能成为候选载波。
规则B：结合B-1，B-2和B-3,UE确定唯一的LBT_Thres(k)。如果“可用的至少一个第一载波”中某一个载波的LBT测量结果大于或等于LBT_Thres(k)，则将相应载波纳入候选载波。
B-1：UE获取基站配置或预配置的一个或多个LBT_Thres(1,2,3,...k,...N)，其中每个LBT_Thres(k)关联一个或多个SL逻辑信道优先级值Priority(1,2,3,...j,...8)。
B-2：LBT成功率的计算定义为(成功的LBT次数除以总LBT次数)；进一步的，还可以限定计算的时间窗，例如从当前时刻回溯到过去的1s内；或者从第一次LBT开始到当前时刻等等。
B-3：UE确定其中最高的SL逻辑信道优先级值，包括以下方法之一：
根据所述SL业务对应的所有SL逻辑信道中取其中最高优先级值；
UE获取基站配置或预配置的SL逻辑信道限制信息，根据所述SL业务对应的所有SL逻辑信道中，先选出其中SL逻辑信道限制为“SL-U only”的逻辑信道，取其中最高优先级值。一个特例，假设此时先选出其中SL逻辑信道限制为“SL-U only”的逻辑信道为0个，则意味着“可用的至少一个第一载波”均不能成为候选载波。
实施例二：有至少一个第一载波和至少一个第二载波共存的多载波场景。
步骤1，UE上层有SL业务到达，上层提供了所述SL业务对应的传输信息。该传输信息包括以下至少一项：

可选地，不同的传输模式满足以下至少一项：
不同的传输模式通过终端上层提供的发送配置(TX profile)携带；
不同的传输模式与至少一个载波频点关联；
不同的传输模式与至少一个业务类型关联；
不同的传输模式与至少一个应用标识关联；
不同的传输模式与至少一个目的层二标识关联；
不同的传输模式与至少一套服务质量参数关联。
步骤2：若根据步骤1的传输信息确定的是“至少一个第一载波和至少一个第二载波”，则存在以下情况：
情况1：如果仅满足条件：“至少一个第一载波”的部分或所有第一载波被包含在基站配置或预配置的SL资源中，则将所述被包含的部分或所有第一载波确定为“可用的至少一个第一载波”，此时候选载波的确定方式可以参照上述实施例一，再次不再赘述。
情况2：如果仅满足条件：“至少一个第二载波”的部分或所有第二载波被包含在基站配置或预配置的SL资源中，则将所述被包含的部分或所有第二载波确定为“可用的至少一个第二载波”，此时候选载波的确定方式可以参照现有的相关机制，在此不再赘述。
情况3：如果满足两个条件：“至少一个第一载波”的部分或所有斗殴载波被包含在基站配置或预配置的SL资源中，且“至少一个第二载波”的部分或所有第二载波被包含在基站配置或预配置的SL资源中，则将所述被包含的部分或所有第一载波以及第二载波确定为“可用的至少一个第一载波和至少一个第二载波”。
针对情况3，假设终端内部第一载波和第二载波不允许同时工作，则继续根据以下规则至少之一确定候选载波：
规则C：控制节点配置或预配置指示工作在SL-U模式或工作在SL模式。如果指示为SL-U模式，则“至少一个第一载波”可纳入候选载波；如果指示为SL模式，则“至少一个第二载波”可纳入候选载波。
规则D：总是优先第一载波或总是优先第二载波。如果规定优先第一载波，则“至少一个第一载波”可纳入候选载波；如果规定优先第二载波，则 “至少一个第二载波”可纳入候选载波。
规则E：在一定条件下优先第一载波，包括以下至少之一：
规则E-1：如果“可用的至少一个第一载波”中的某个第一载波测量结果满足阈值条件(使用规则A或B)，则将相应载波纳入候选载波；只有当“可用的至少一个第一载波”中的所有第一载波测量结果均不满足阈值条件(使用规则A或B)，才将“可用的至少一个第二载波”纳入候选载波；
规则E-2：UE获取基站配置或预配置的SL逻辑信道限制信息，根据逻辑信道限制信息确定当待传SL业务中逻辑信道限制为“SL-U only”中的所有逻辑信道的最高优先级高于或等于待传SL业务中逻辑信道限制为“SL only”中的所有逻辑信道的最高优先级，则“至少一个第一载波”可纳入候选载波。
规则E-3：选出“可用的至少一个SL-U载波”中测量结果最好的载波1，以及“可用的至少一个第二载波”中测量结果最好的载波2；当载波1测量结果大于预设阈值1且载波2小于预设阈值2，则优先第一载波；否则优先第二载波。
规则F：在一定条件下优先第二载波，包括以下至少之一：
规则F-1：如果“可用的至少一个第二载波”中的某个第二载波测量结果满足阈值条件(现有测量量，例如CBR，SL-RSRP)，则将相应载波纳入候选载波；只有当“可用的至少一个第二载波”中的所有第二载波测量结果均不满足阈值条件(使用规则A或B)，才将“至少一个第一载波”纳入候选载波；
规则F-2：UE获取基站配置或预配置的SL逻辑信道限制信息，根据逻辑信道限制信息确定当待传SL业务中逻辑信道限制为“SL only”中的所有逻辑信道的最高优先级高于或等于待传SL业务中逻辑信道限制为“SL-U only”中的所有逻辑信道的最高优先级，则“至少一个第二载波”可纳入候选载波
规则F-3：选出“可用的至少一个第一载波”中测量结果最好的载波1，以及“可用的至少一个第二载波”中测量结果最好的载波2；当载波1测量结果小于预设阈值1且载波2大于预设阈值2，则优先第二载波；否则优先第一载波。
针对情况3，假设UE内部第一载波和第二载波可以同时工作，则定义 SL-U和SL资源冲突的解决机制以及SL MAC PDU发送优先机制，包括以下至少之一：
规则G：总是优先第一载波的授权资源(以下称之为第一资源)或第二载波的授权资源(以下称之为第二资源)。
规则G-1：总是优先第一资源，并将其用于“SL-U类型”关联的至少一个逻辑信道复用发送的SL MAC PDU，丢弃所述第二资源，如果UE工作在SL mode 2，则触发SL mode 2资源重选。
规则G-2：总是优先第二资源，并将其用于“SL类型”关联的至少一个逻辑信道复用发送的SL MAC PDU，丢弃所述第一资源。
规则H：根据待传SL业务中“SL-U类型”关联的至少一个逻辑信道优先级与“SL类型”关联的至少一个逻辑信道优先级进行比较，基于比较结果确定传输行为。
规则H-1：如果待传SL业务中“SL-U类型”关联的至少一个逻辑信道中的最高优先级高于或等于待传SL业务中“SL类型”关联的至少一个逻辑信道中的最高优先级，则优先第一资源，并将其用于“SL-U类型”关联的至少一个逻辑信道复用发送的SL MAC PDU，丢弃所述第二资源；如果UE工作在SL mode 2，则触发资源重选。
规则H-2:如果待传SL业务中“SL类型”关联的至少一个逻辑信道中的最高优先级高于或等于待传SL业务中“SL-U类型”关联的至少一个逻辑信道中的最高优先级，则优先第二资源，并将其用于“SL类型”关联的至少一个逻辑信道复用发送的SL MAC PDU，丢弃所述第一资源；如果UE工作在SL mode 2，则触发资源重选。
可选地，“SL-U类型”关联的至少一个逻辑信道可以理解为非授权频段关联的逻辑信道，也可以理解为仅用于非授权频段的逻辑信道；“SL类型”关联的至少一个逻辑信道可以理解为授权频段关联的逻辑信道，也可以理解为仅用于授权频段的逻辑信道。
需要说明的是，本申请实施例提供的SL业务传输处理方法，执行主体可以为SL业务传输处理装置，或者，该SL业务传输处理装置中的用于执行SL业务传输处理方法的控制模块。本申请实施例中以SL业务传输处理装置执行 SL业务传输处理方法为例，说明本申请实施例提供的SL业务传输处理装置。
