Description

数据传输方法、装置及存储介质
本申请要求在2019年08月08日提交中国专利局、申请号为201910731645.5的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信网络，例如涉及一种数据传输方法、装置及存储介质。
背景技术
在车联网系统中，基于无线通信的对象可以将车联网通信划分为三种不同的类型：车辆与车辆之间通信(Vehicle-to-Vehicle，V2V)，车辆与路边设备/网络基础设施之间通信(Vehicle-to-Infrastructure/Vehicle-to-Network，V2I/V2N)，以及车辆与行人之间通信(Vehicle-to-Pedestrian，V2P)，这三种通信方式统称为V2X通信。
在3GPP(3rd Generation Partnership Project)组织的基于长期演进(Long Term Evolution，LTE)的V2X通信研究中，基于用户设备(User Equipment，UE)之间的V2X通信是V2X标准实现的方式之一。如图1所示，这种通过直通链路/旁链链路(Sidelink)直接由源UE通过空口传输给目标UE的通信方式称为PC5-based V2X通信或Sidelink V2X通信。
但是对于一个具备Sidelink通信能力的UE而言，在同一时刻可能需要同时发送上行数据和Sidelink数据。若UE能力有限或者UE受到同频干扰等原因，则导致UE不能同时发送这两类数据。
发明内容
本申请提供一种数据传输方法、装置及存储介质，能够解决UE传输业务时的冲突问题。
本申请实施例提供了一种数据传输方法，包括：

本申请实施例提供了一种数据传输装置，包括：
确定模块，设置为确定数据传输装置不能同时传输UL业务和SL业务；
比较模块，设置为比较UL通道和SL通道的优先级；
通信模块，设置为根据比较结果传输业务。
本申请实施例提供了一种数据传输装置，包括：
确定模块，设置为确定至少一个SL BSR被触发且未被取消；

具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不 冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
另外，在本申请实施例中，“可选地”或者“示例性地”等词用于表示作例子、例证或说明。确切而言，使用“可选地”或者“示例性地”等词旨在以具体方式呈现相关概念。
本申请实施例可以应用于Sidelink通信场景下，具体地，可以应用于Sidelink单播、Sidelink组播以及Sidelink广播，能够实现当设备传输业务时，若存在资源冲突的情况下，即设备不能同时传输所有业务时，以合理的资源分配方案来确定业务的传输顺序。
图2为一实施例提供的一种数据传输方法的流程图，如图2所示，本实施例提供的方法包括如下步骤：
S201、若UE确定不能同时传输UL业务和SL业务时，比较UL通道和SL通道的优先级。
示例性地，当多个业务在不同的频点传输并且需要共用UE的发送链路，或者，多个业务在相同频点传输时，若UE由于能力限制或数据传输会受到同频干扰等原因不能同时发送多个业务，则UE确定在该时刻，其自身不能同时传输UL业务和SL业务。
进而，UE比较UL通道和SL通道的优先级，以优先传输优先级较高的通道上所承载的业务。
S202、UE根据比较结果传输业务。
当UE确定的比较结果为SL通道的优先级高于UL通道的优先级，则UE优先传输SL业务。
可选地，本申请实施例提供一种确定SL通道的优先级高于UL通道的优先级的实现方式为，SL通道的逻辑信道优先级高于UL通道的逻辑信道优先级。
示例性地，确定SL通道的逻辑信道优先级高于UL通道的逻辑信道优先级可以采用以下几种判断方式：
方式一、SL通道的逻辑信道优先级值小于UL通道的逻辑信道优先级值。
本领域技术人员可以理解的是，优先级值越小，表示优先级排名越靠前，即优先级越高。
需要说明的是，在本申请实施例中，描述的逻辑信道优先级值可以为逻辑信道的最高优先级值。
方式二、SL通道的逻辑信道优先级值小于第一门限，并且，SL通道的逻辑信道优先级值小于UL通道的逻辑信道优先级值。
在一实施例中，获取第一门限的方式可以为，网络侧通过系统消息或者无线资源控制(Radio Resource Control，RRC)消息将第一门限下发至UE。
方式三、UL通道的逻辑信道优先级值大于第二门限，且所述SL通道的逻辑信道的优先级值小于第一门限。
当UL通道的逻辑信道优先级值大于第二门限，以及，SL通道的逻辑信道的优先级值小于第一门限这两个条件均满足时，确认SL通道的逻辑信道优先级高于UL通道的逻辑信道优先级，UE优先传输SL通道上的SL业务。
同样地，本申请实施例中涉及的第二门限也可以为网络侧通过系统消息或者RRC消息下发至UE。
方式四、UL通道的逻辑信道优先级值大于第二门限，且SL数据包的时延参数小于第一时延门限。
当UL通道的逻辑信道优先级值大于第二门限，表示UL通道的逻辑信道优先级排名靠后，优先级较低。同时，当SL数据包的时延参数小于第一时延门限时，表示该SL数据包的时延较小。因此，可以优先传输SL数据包。而由于SL数据包在SL通道上传输，因此，可以认为，SL通道的逻辑信道优先级高于UL通道的逻辑信道优先级。
其中，获取第一时延门限的方式可以为，网络侧通过系统消息或者RRC消息将第一时延门限下发至UE。
方式五、SL通道的逻辑信道优先级值小于UL通道的逻辑信道优先级值和媒体访问控制层(Media Access Control，MAC)控制单元(Control Element，CE)的优先级值。
当SL通道的逻辑信道优先级值同时小于UL通道的逻辑信道优先级值和MAC CE的优先级值时，表示SL通道的逻辑信道优先级排名在UL通道的逻辑信道优先级和MAC CE的优先级之前，即SL通道的逻辑信道优先级较高。
在本申请实施例中，获取MAC CE的优先级值的实现方式可以为，UE接收网络侧通过系统消息或者RRC消息发送的MAC CE的优先级值。
其中，MAC CE的优先级值包括N个MAC CE中每个MAC CE的优先级值，或者，网络侧为N个MAC CE统一配置的优先级值，或者，网络侧为非填充字段non padding MAC CE配置的优先级值，或者，网络侧为填充字段padding MAC CE配置的优先级值。其中，N为自然数。
方式六、SL数据包的时延参数小于第一时延门限，且SL通道的逻辑信道优先级值小于UL通道的逻辑信道优先级值。
当SL数据包的时延参数小于第一时延门限时，表示该SL数据包的时延较小。在一实施例中，若SL通道的逻辑信道优先级值小于UL通道的逻辑信道优先级值，则表示SL通道的逻辑信道优先级高于UL通道的逻辑信道优先级，UE可以优先传输SL通道上的SL数据包。
方式七、SL通道的逻辑信道优先级值小于第一门限。
可选地，当UE的MAC协议数据单元(Protocol Data Unit，PDU)中未包括MAC CE时，确定SL通道的逻辑信道优先级高于UL通道的逻辑信道优先级可以采用以下两种方式实现：
第一种实现方式：SL通道的逻辑信道的优先级值大于第一门限，且SL通道的逻辑信道优先级值小于UL通道的逻辑信道优先级值。
当SL通道的逻辑信道的优先级值大于第一门限时，若SL通道的逻辑信道优先级值小于UL通道的逻辑信道优先级值，则可以确定SL通道的逻辑信道优先级高于UL通道的逻辑信道优先级。
第二种实现方式：SL数据包的时延参数大于第一时延阈值，且SL通道的逻辑信道优先级值小于UL通道的逻辑信道优先级值。
当SL数据包的时延参数大于第一时延阈值，即SL数据包的时延较大时，若SL通道的逻辑信道优先级值小于UL通道的逻辑信道优先级值，则可以确定SL通道的逻辑信道优先级高于UL通道的逻辑信道优先级。
可选地，当SL通道上配置的为多次重传的数据包时，本申请实施例提供一种确定SL通道的优先级高于UL通道的优先级的实现方式为，SL MAC PDU重传业务优先级高于UL MAC PDU首传业务的优先级，其中，SL MAC PDU重传业务在SL通道上传输，UL MAC PDU首传业务在UL通道上传输。
需要说明的是，上述重传包括不基于反馈的重传以及基于反馈的重传两种情形。
示例性地，确定SL MAC PDU重传业务优先级高于UL MAC PDU首传业务的优先级可以采用以下几种方式实现：
方式一、SL通道的逻辑信道优先级值小于第一门限，且UL通道的逻辑信道优先级值大于第三门限。
在同时满足SL通道的逻辑信道优先级值小于第一门限和UL通道的逻辑信道优先级值大于第三门限这两种情况时，确定SL MAC PDU重传业务优先级高于UL MAC PDU首传业务的优先级，也即SL通道的优先级高于UL通道的优先级。
同样地，上述第三门限的获取方式也可以为网络侧通过系统消息或者RRC消息下发至UE。
方式二、SL MAC PDU重传业务的优先级值小于第四门限。
当SL MAC PDU重传业务的优先级值小于第四门限时，表示SL MAC PDU重传业务的优先级满足“SL MAC PDU重传业务优先级高于UL MAC PDU首传业务的优先级”这一条件，也即传输SL MAC PDU重传业务的SL通道的优先级高于传输UL MAC PDU首传业务的UL通道的优先级。
类似地，在本申请实施例中，可以由网络侧通过系统消息或者RRC消息下发第四门限至UE。
方式三、UE接收网络侧通过系统消息或者RRC消息发送的指示消息，该指示消息用于指示SL MAC PDU重传业务优先级高于所述UL MAC PDU首传业务优先级。
在一实施例中，当UE上未配置SL通道的逻辑信道优先级时，本申请实施例还提供一种实现方式为，UE接收网络侧通系统消息或者RRC消息发送的直通链路接口服务质量流标识/PC5接口上的第五代移动通信技术服务质量标识(PC5QoS flow identifier/PC5 5G QoS identifier，PFI/PQI)与逻辑信道优先级之间的对应关系，以使得UE根据该对应关系确定SL通道的逻辑信道优先级。
当UE确定的比较结果为UL通道的优先级高于SL通道的优先级时，UE优先传输UL业务。
可选地，本申请实施例提供一种确定UL通道的优先级高于SL通道的优先级的实现方式为：
UL通道的逻辑信道优先级值小于第二门限。
当UL通道的逻辑信道优先级值小于第二门限时，可以确定该UL通道的逻辑信道优先级高于SL通道的逻辑信道优先级，也即UL通道的优先级高于SL通道的优先级。此时，UE优先传输UL通道上的UL业务。
或者，UL数据包的时延参数小于第一时延门限。
当UL数据包的时延参数小于第一时延门限时，表示该UL数据包的时延较小，可以优先传输UL数据包。也即UL通道的优先级高于SL通道的优先级。
可选地，当SL通道上配置的为多次重传的数据包时，本申请实施例提供一种确定UL通道的优先级高于SL通道的优先级的实现方式为，UE接收网络侧通过系统消息或者RRC消息下发的指示消息，该指示消息用于指示UL MAC PDU首传业务优先级高于SL MAC PDU重传业务优先级，其中，SL MAC PDU 重传业务在SL通道上传输，UL MAC PDU首传业务在UL通道上传输。
需要说明的是，上述重传包括不基于反馈的重传以及基于反馈的重传两种情形。
当UE确定的比较结果为SL通道的优先级等于UL通道的优先级时，本申请实施例提供以下两种确定传输业务的实现方式：
方式一、UE选择SL通道和UL通道中的任意一个通道传输业务。
方式二、UE基于资源类型、数据包误码率、数据包延时参数中的至少一项比较SL通道和UL通道的优先级，并优先传输优先级高的通道上的业务。
例如，在SL通道和UL通道中，数据包时延参数小的通道，其优先级更高。
但对于PC5信令承载(Signaling Radio Bearer，SRB)而言，若SRB和数据承载(Data Radio Bearer，DRB)的时延参数相同时，可以由UE选择SL通道和UL通道中的任意一个通道传输业务，或者，默认SRB的优先级高于DRB的优先级，即传输SRB的通道具有更高的优先级。
其中，本领域技术人员熟知的是，PC5是在Sidelink上定义的接口，本申请实施例对此不作详细说明。
当SL业务包括长期演进技术(Long Term Evolution，LTE)SL业务和新空口(New Radio，NR)SL业务时，若UE不能同时传输LTE SL业务和NR SL业务，本申请实施例提供了一种可选的实现方式为，若LTE SL MAC PDU中逻辑信道的优先级值小于NR SL MAC PDU中逻辑信道的优先级值，则UE优先传输LTE SL业务。
反之，若LTE SL MAC PDU中逻辑信道的优先级值大于NR SL MAC PDU中逻辑信道的优先级值，则UE优先传输NR SL业务。
当UE以多连接方式接入多个小区时，UE需要同时发送NR SL、LTE SL、NR UL以及LTE UL，若UE不能同时传输所有的SL业务(例如，NR SL业务和LTE SL业务)和所有的UL业务(例如，NR UL业务和LTE UL业务)，本申请实施例提供了一种可选的实现方式为：
UE比较NR SL逻辑信道、LTE SL近距离通信数据分组优先级(ProSe Per-Packet Priority，PPPP)、NR UL逻辑信道以及LTE UL逻辑信道之间的优先级，并优先传输优先级较高的业务。
或者，UE比较LTE SL MAC PDU中逻辑信道的优先级值与LTE阈值，若LTE SL MAC PDU中逻辑信道的优先级值小于LTE阈值，则LTE SL业务的优先级高于LTE UL业务的优先级，UE优先传输LTE SL业务。
或者，UE比较NR SL MAC PDU中逻辑信道的优先级值与NR阈值，若NR SL MAC PDU中逻辑信道的优先级值小于NR阈值，则NR SL业务的优先级高于NR UL业务的优先级，UE优先传输NR SL业务。
其中，LTE阈值和NR阈值由网络侧通过系统消息或者RRC消息发送至UE。
当UE接入某个小区时，UE需要同时传输NR SL业务、LTE SL业务以及UL数据业务，若UE不能同时传输SL业务和UL业务时，本申请实施例提供一种可选地实现方式为，UE比较UL通道的逻辑信道、NR SL逻辑信道以及LTE SL PPPP之间的优先级，并优先传输优先级较高的业务。
当UE接入某个基站时，UE需要同时传输NR SL业务、LTE SL业务以及UL数据业务，若UE不能同时传输SL业务和UL业务时，本申请实施例提供一种可选地实现方式为：
若NR SL逻辑信道优先级值小于预设阈值，LTE SL逻辑信道优先级值大于预设阈值，则确认NR SL业务的优先级较高，UE优先传输NR SL业务，其次传输LTE SL业务，并当UE有传输能力或传输资源时，再传输UL数据业务。
或者，若LTE SL逻辑信道的优先级值小于预设阈值，NR SL逻辑信道优先级值大于预设阈值，则确认LTE SL业务的优先级较高，UE优先传输LTE SL业务，其次传输UL SL业务，并当UE有传输能力或传输资源时，再传输UL数据业务。
或者，若NR SL逻辑信道优先级值和LTE SL逻辑信道的优先级值均小于预设阈值，则UE比较NR SL逻辑信道优先级和LTE SL PPPP的优先级，并优先传输优先级较高的SL业务。当UE有传输能力或传输资源时，再依次传输另外一个优先级较低的SL业务和UL数据业务。
或者，若NR SL逻辑信道优先级值和LTE SL逻辑信道的优先级值均小于预设阈值，则UE比较NR SL逻辑信道优先级和LTE SL PPPP的优先级，并优先传输UL数据业务。当UE有传输能力或传输资源时，再按照优先级高低的顺序，依次传输两个SL业务。
本申请实施例提供的数据传输方法，在UE确定不能同时传输UL业务和SL业务时，对UL通道和SL通道的优先级进行比较，并根据比较结果传输业务。这样能够在UE不能同时传输所有的UL业务和SL业务时，以合理的资源分配方案确定业务的传输顺序，避免业务传输过程中的冲突问题。
图3为一实施例提供的一种数据传输方法的流程图，如图3所示，本实施例提供的方法包括如下步骤：
S301、至少一个单边通信缓存状态报告SL BSR被触发且未被取消。
示例性地，在本申请实施例中，可以为UE的MAC实体确定至少一个单边通信缓存状态报告SL BSR被触发且未被取消。
S302、若用户设备UE在传输时间间隔TTI分配了上行通信UL资源，并且UL资源可以容纳SL BSR以及SL BSR的子头，则UE生成SL BSR MAC控制单元。
可选地，在上述条件“UE在TTI分配了UL资源，并且UL资源可以容纳SL BSR以及SL BSR的字头”满足的情况下，本申请实施例中还提供了以下步骤：
若所有产生的SL BSR都不是截断(Truncated)SL BSR，则UE开启或者重启周期SL BSR定时器；
开启或者重启重传SL BSR定时器。
反之，如果不满足“UE在TTI分配了UL资源，并且该UL资源可以容纳SL BSR以及SL BSR的子头”这一条件，但是Regular Sidelink BSR被触发了，那么，进一步地：

图4为一实施例提供的一种数据传输装置的结构示意图，如图4所示，本实施例提供的装置包括：确定模块401、比较模块402和通信模块403。
其中，确定模块401，设置为确定数据传输装置不能同时传输UL业务和SL业务；
比较模块402，设置为比较UL通道和SL通道的优先级；
通信模块403，设置为根据比较结果传输业务。
在一实施例中，通信模块403是设置为当比较结果为SL通道的优先级高于UL通道的优先级，传输SL业务。
其中，SL通道的优先级高于UL通道的优先级的一种可能实现方式为：
SL通道的逻辑信道优先级高于UL通道的逻辑信道优先级。
在一实施例中，确定SL通道的逻辑信道优先级高于所述UL通道的逻辑信道优先级，可以采用以下几种实现方式：
方式一、SL通道的逻辑信道优先级值小于UL通道的逻辑信道优先级值；
方式二、SL通道的逻辑信道优先级值小于第一门限，且SL通道的逻辑信道优先级值小于UL通道的逻辑信道优先级值；
方式三、UL通道的逻辑信道优先级值大于第二门限，且SL通道的逻辑信道的优先级值小于第一门限；
方式四、UL通道的逻辑信道优先级值大于第二门限，且SL数据包的时延参数小于第一时延门限；
方式五、SL通道的逻辑信道优先级值小于UL通道的逻辑信道优先级值和MAC CE的优先级值；
方式六、SL数据包的时延参数小于第一时延门限，且SL通道的逻辑信道优先级值小于UL通道的逻辑信道优先级值。
方式七、SL通道的逻辑信道优先级值小于第一门限。
在一实施例中，通信模块403设置为接收网络侧通过系统消息或者RRC消息发送的MAC CE的优先级值；
其中，MAC CE的优先级值包括N个MAC CE中每个MAC CE的优先级值，或者，网络侧为N个MAC CE统一配置的优先级值，或者，网络侧为非填充字段non padding MAC CE配置的优先级值，或者，网络侧为填充字段padding MAC CE配置的优先级值，N为自然数。
通信模块还设置为接收网络侧通过系统消息或者RRC消息发送的第一时延门限。
当数据传输装置的MAC PDU中未包括有MAC CE时，SL通道的逻辑信道优先级高于UL通道的逻辑信道优先级，可以采用以下方式判断：
第一种实现方式，SL通道的逻辑信道的优先级值大于第一门限，且SL通 道的逻辑信道优先级值小于UL通道的逻辑信道优先级值；
第二种实现方式，SL数据包的时延参数大于第一时延阈值，且SL通道的逻辑信道优先级值小于UL通道的逻辑信道优先级值。
在一实施例中，当SL通道上配置的为多次重传数据包时，SL通道的优先级高于UL通道的优先级的另一种实现方式为：
SL MAC PDU重传业务优先级高于UL MAC PDU首传业务优先级；
其中，SL MAC PDU重传业务在SL通道上传输，UL MAC PDU首传业务在UL通道上传输。
其中，SL MAC PDU重传业务优先级高于UL MAC PDU首传业务优先级，可以采用以下方式实现：
方式一、SL通道的逻辑信道优先级值小于第一门限，且UL通道的逻辑信道优先级值大于第三门限；
方式二、SL MAC PDU重传业务的优先级值小于第四门限；
方式三、通信模块403接收网络侧通过系统消息或者RRC消息发送的指示消息，指示消息指示SL MAC PDU重传业务优先级高于UL MAC PDU首传业务优先级。
需要说明的是，上述重传包括不基于反馈的重传以及基于反馈的重传两种情形。
在一实施例中，通信模块403设置为接收网络侧通过系统消息或者RRC消息发送的第一门限、第二门限、第三门限、第四门限。
当确定模块401确定的比较结果为UL通道的优先级高于SL通道的优先级时，通信模块403优先传输UL业务。
可选地，本申请实施例提供一种确定UL通道的优先级高于SL通道的优先级的实现方式为：
UL通道的逻辑信道优先级值小于第二门限。
当UL通道的逻辑信道优先级值小于第二门限时，确定模块401确定该UL通道的逻辑信道优先级高于SL通道的逻辑信道优先级，也即UL通道的优先级高于SL通道的优先级。此时，通信模块403优先传输UL通道上的UL业务。
或者，UL数据包的时延参数小于第一时延门限。
当UL数据包的时延参数小于第一时延门限时，表示该UL数据包的时延较小，可以优先传输UL数据包。也即UL通道的优先级高于SL通道的优先级。
可选地，当SL通道上配置的为多次重传的数据包时，本申请实施例提供一种确定UL通道的优先级高于SL通道的优先级的实现方式为，通信模块403接收网络侧通过系统消息或者RRC消息下发的指示消息，该指示消息用于指示UL MAC PDU首传业务优先级高于SL MAC PDU重传业务优先级，其中，SL MAC PDU重传业务在SL通道上传输，UL MAC PDU首传业务在UL通道上传输。
需要说明的是，上述重传包括不基于反馈的重传以及基于反馈的重传两种情形。
若比较结果为SL通道的优先级等于UL通道的优先级，则数据传输装置选择SL通道和UL通道中的任意一个通道传输业务；
或者，数据传输装置基于资源类型、数据包误码率、数据包延时参数中的至少一项比较SL通道和所述UL通道的优先级。
另外，当SL业务包括LTE SL业务和NR SL业务时，若LTE SL MAC PDU中逻辑信道的优先级值小于NR SL MAC PDU中逻辑信道的优先级值，则通信模块403优先传输LTE SL业务。
当数据传输装置以多连接方式接入多个小区时，若确定模块401确认LTE SL MAC PDU中逻辑信道的优先级值小于LTE阈值，则通信模块403优先传输LTE SL业务；
若确认模块401确认NR SL MAC PDU中逻辑信道的优先级值小于NR阈值，则通信模块403优先传输NR SL业务；
其中，LTE阈值和NR阈值由网络侧通过系统消息或者RRC消息发送至通信模块。
当数据传输装置未配置SL通道的逻辑信道优先级时，通信模块403设置为接收网络侧通过系统消息或者RRC消息发送的PFI/PQI与逻辑信道优先级的对应关系；
确定模块401根据对应关系确定SL通道的逻辑信道优先级。
当SL业务包括LTE SL业务和NR SL业务时，若数据传输装置不能同时传输LTE SL业务和NR SL业务，本申请实施例提供了一种可选的实现方式为，若LTE SL MAC PDU中逻辑信道的优先级值小于NR SL MAC PDU中逻辑信道的优先级值，则通信模块403优先传输LTE SL业务。
反之，若LTE SL MAC PDU中逻辑信道的优先级值大于NR SL MAC PDU中逻辑信道的优先级值，则通信模块403优先传输NR SL业务。
当数据传输装置以多连接方式接入多个小区时，需要同时发送NR SL、LTE SL、NR UL以及LTE UL，若确定模块401确定数据传输装置不能同时传输所有的SL业务(例如，NR SL业务和LTE SL业务)和所有的UL业务(例如，NR UL业务和LTE UL业务)，本申请实施例提供了一种可选的实现方式为：
比较模块402比较NR SL逻辑信道、LTE SL PPPP、NR UL逻辑信道以及LTE UL逻辑信道之间的优先级，并由通信模块403基于比较结果优先传输优先级较高的业务。
或者，比较模块402比较LTE SL MAC PDU中逻辑信道的优先级值与LTE阈值，若LTE SL MAC PDU中逻辑信道的优先级值小于LTE阈值，则LTE SL业务的优先级高于LTE UL业务的优先级，通信模块403优先传输LTE SL业务。
或者，比较模块402比较NR SL MAC PDU中逻辑信道的优先级值与NR阈值，若NR SL MAC PDU中逻辑信道的优先级值小于NR阈值，则NR SL业务的优先级高于NR UL业务的优先级，通信模块403优先传输NR SL业务。
其中，LTE阈值和NR阈值由网络侧通过系统消息或者RRC消息发送至数据传输装置。
当数据传输装置接入某个小区时，需要同时传输NR SL业务、LTE SL业务以及UL数据业务，若确定模块401确定数据传输装置不能同时传输SL业务和UL业务时，本申请实施例提供一种可选地实现方式为，比较模块402比较UL通道的逻辑信道、NR SL逻辑信道以及LTE SL PPPP之间的优先级，并由通信模块403优先传输优先级较高的业务。
当数据传输装置接入某个基站时，需要同时传输NR SL业务、LTE SL业务以及UL数据业务，若确定模块401确定数据传输装置不能同时传输SL业务和UL业务时，本申请实施例提供一种可选地实现方式为：
若NR SL逻辑信道优先级值小于预设阈值，LTE SL逻辑信道优先级值大于预设阈值，则确认NR SL业务的优先级较高，通信模块403优先传输NR SL业务，其次传输LTE SL业务，并当通信模块403有传输能力或传输资源时，再传输UL数据业务。
或者，若LTE SL逻辑信道的优先级值小于预设阈值，NR SL逻辑信道优先级值大于预设阈值，则确认LTE SL业务的优先级较高，通信模块403优先传输LTE SL业务，其次传输UL SL业务，并当通信模块403有传输能力或传输资源时，再传输UL数据业务。
或者，若NR SL逻辑信道优先级值和LTE SL逻辑信道的优先级值均小于预设阈值，则比较模块402比较NR SL逻辑信道优先级和LTE SL PPPP的优先 级，并由通信模块403优先传输优先级较高的SL业务。当通信模块403有传输能力或传输资源时，再依次传输另外一个优先级较低的SL业务和UL数据业务。
或者，若NR SL逻辑信道优先级值和LTE SL逻辑信道的优先级值均小于预设阈值，则比较模块402比较NR SL逻辑信道优先级和LTE SL PPPP的优先级，并由通信模块403优先传输UL数据业务。当通信模块403有传输能力或传输资源时，再按照优先级高低的顺序，依次传输两个SL业务。
