具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
本公开的以下实施例中，逻辑信道配置中用于QoS保障的参数包括：
Priority，参数值越低优先级越高；
allowedServingCells，该逻辑信道数据传输允许使用的小区；
allowedSCS-List，该逻辑信道数据传输允许使用的子载波间隔；
maxPUSCH-Duration，该逻辑信道数据传输可使用的最大PUSCH长度，基站分配的上行PUSCH资源时间长度不大于该参数时终端才可以把该逻辑信道的数据映射到该PUSCH上；
configuredGrantType1Allowed，是否允许使用配置资源类型1的预配置资源；
allowedCG-List：允许使用的预配置资源组列表。
UE内优先级，当终端获取到两个或更多个时域上有交叠的上行传输资源时(即上行资源冲突)，终端只能在其中一个上行资源上发送上行数据，因此，UE内优先级可以保障高优先级业务的传输。
UE内优先级包括MAC层优先级和物理层优先级两方面。
MAC层优先级基本思想是指，当基站为终端配置了基于逻辑信道的优先级(lch-BasedPrioritization)时，当两个上行资源冲突时，终端比较映射到两个上行资源的数据的逻辑信道优先级，优先传输包含更高优先级逻辑信道数据的上行资源。
物理层优先级是指，对于预配置资源：基站为终端在预配置资源CG中配置(ConfiguredGrantConfig)中配置该预配置资源的物理层优先级phy-PriorityIndex为p0或p1，p0表示低优先级、p1表示高优先级；对于动态调度资源，基站在逻辑信道配置(LogicalChannelConfig)中配置对应上行资源的优先级allowedPHY-PriorityIndex，基站调度上行资源的动态调度命令中 包含该动态调度资源的优先级指示p0或者p1，逻辑信道数据只允许映射到对应优先级的上行动态调度资源上。基站在动态调度命令中携带优先级指示，如果两个上行资源冲突，只允许在优先级高的上行资源上发送上行传输。
上述逻辑信道优先级，传输优先级对于确定的业务是配置好的，对于一种业务的数据，只要不对上述参数进行重新配置，每个业务数据包的QoS保障力度都是一样的，即具有相同的时延、可靠性等性能参数预算。
工业互联网中引入了存活时间(survival time)的概念，该参数用于表征业务的可用性。工业互联网中，部分周期性确定性通信业务的业务需求参数如下表，除了传输间隔、消息大小、时延等传统参数外，还引入了survival time。
表1:周期性确定性通信业务的性能需求(Periodic deterministic communication service performance requirements)
Figure PCTCN2021123042-appb-000001
Survival time的定义如图1，当数据传输错误，启动survival time，如果survival time有效期间后续数据可以正确传输，则认为该业务传输是可用的(availability)，如果survival time超时，数据仍不能正确传输，则认为源设备和目标设备之间的传输是不可用的。
如图2所示，本公开的实施例提供一种数据传输方法，应用于终端，所述方法包括：
步骤21，在发生业务数据传输错误时，根据触发条件，提高业务数据传输优先级；
步骤22，按照提高后的业务数据传输优先级，进行所述业务数据的传输。
本公开的该实施例中，终端在发生业务数据传输错误时，提高该业务数据的传输优先级，以降低发生传输链路不可用的概率，从而提高工业互联网中整体业务数据传输可行性。

本公开的一可选的实施例中，所述触发条件根据以下至少一种情况确定：
协议约定的方式；
终端自行决策的方式；
网络侧配置的方式。
其中，所述触发条件根据网络侧配置的方式确定时，所述网络侧配置的参数包括以下至少一项：

没有成功接收的无线链路控制服务数据单元RLC SDU的个数或者在配置时间段内没有成功接收到的RLC SDU个数；
分组数据汇聚协议PDCP重排序后出现间隔gap的个数；
配置触发定时器，所述定时器在发生业务数据传输错误后启动，如果所述定时器超时后仍存在数据传输错误，则认为满足提高业务数据传输优先级的触发条件。
本公开的一可选的实施例中，提高业务数据传输优先级，包括以下至少一项：
(1)终端接收网络侧发送的第一配置信息，按照所述第一配置信息提高业务数据传输优先级，所述第一配置信息用于配置允许提高业务数据传输优先级的服务质量流QoS flow、承载RB或逻辑信道；
该实施例中，网络侧(如基站)配置允许终端针对特定业务(针对QoS flow或RB或逻辑信道配置)提高传输优先级(如boostPriorityAllowed)。
一种实现实例中，基站允许提高优先级，终端自行实现：
基站配置允许提高优先级级参数(如boostPriorityAllowed)，针对QoS flow或RB或逻辑信道配置；可选的，基站配置发生业务数据传输错误的触发条件。
终端接收基站关于业务优先级提升的配置参数；根据基站配置或协议规定或自行决策，判断发生传输错误；优先传输该QoS flow或RB或逻辑信道的后续数据，具体如何传取决于终端实现，基站不做规定。
(2)终端接收网络侧发送的第二配置信息，按照所述第二配置信息提高业务数据传输优先级，所述第二配置信息允许终端在指定的逻辑信道发生业务数据传输错误时，提高所述逻辑信道配置中的优先级参数到最高优先级或指定优先级；
该实施例中，网络侧(如基站)配置允许终端在发生传输错误时，提高逻辑信道配置中的priority参数到最高优先级或指定优先级，终端在进行数据映射到MAC PDU时，按照新的优先级进行映射。
一种实现实例中，提高逻辑信道优先级，优先映射该逻辑信道数据到上行资源：
基站配置针对特定逻辑信道允许提高逻辑信道优先级，可选的，指定提升到的逻辑信道优先级，如原逻辑信道优先级为3，提升为2；如不指定，可直接提升到最高逻辑信道优先级1；可选的，基站配置发生业务数据传输错误的触发条件。
终端接收基站关于提高逻辑信道优先级的配置；根据基站配置或协议规定或自行决策，判断发生传输错误；提高发生传输错误的逻辑信道的优先级，在MAC PDU组织时，使用更新的逻辑信道优先级执行数据映射到上行资源的过程。
(3)终端接收网络侧发送的第三配置信息，按照所述第三配置信息提高业务数据传输优先级，所述第三配置信息允许终端在指定的逻辑信道发生业务数据传输错误时，忽略所述逻辑信道的逻辑信道优先级配置中逻辑信道限制中的至少一个；
该实施例中，网络侧(如基站)配置终端在发生传输错误时，允许忽略逻辑信道限制中的一个或多个或全部，这些逻辑信道限制包括：allowedServingCells，allowedSCS-List，maxPUSCH-Duration，configuredGrantType1Allowed，allowedCG-List。其中，忽略逻辑信道限制即这些限制条件不生效(即失效)；
例如，allowedServingCells失效表示这个逻辑信道可以在终端的所有可用小区下传输；allowedSCS-List失效表示不限制可用的SCS，该逻辑信道的数据可以在任意子载波间隔的资源分配上传输；maxPUSCH-Duration失效表示该逻辑信道数据可以在任何长度的PUSCH资源上传输；configuredGrantType1Allowed失效表示表示该逻辑信道可以使用预配置资源类型1配置的资源；allowedCG-List失效表示该逻辑信道可以使用任何预配置资源。
一种实现实例中，放松逻辑信道限制：
基站配置终端在发生传输错误时，允许忽略逻辑信道限制中的一个或多个或全部，这些逻辑信道限制包括：allowedServingCells，allowedSCS-List， maxPUSCH-Duration，configuredGrantType1Allowed，allowedCG-List；可选的，基站配置发生业务数据传输错误的触发条件。
终端接收基站关于放松逻辑信道限制的配置；根据基站配置或协议规定或自行决策，判断发生传输错误；在MAC PDU组织时，不考虑基站配置确定放松的限制条件，执行数据映射到上行资源的过程。
(4)终端接收网络侧发送的第四配置信息，按照所述第四配置信息提高业务数据传输优先级，所述第四配置信息允许终端在指定的逻辑信道发生业务数据传输错误时，在后续传输中，如果发生上行传输资源冲突，提高所述逻辑信道数据映射到的媒体访问控制分组数据单元MAC PDU的优先级到最高级或指定等级；
该实施例中，针对MAC层UE内优先级方案，基站配置允许终端发生传输错误时，可以提高对应逻辑信道的优先级到最高级(例如priority＝3提高到1)或指定等级(例如priority＝3提高到2)，作为冲突上行资源的传输判断准则，这里不改变终端将逻辑信道数据映射到MAC PDU时的逻辑信道优先级。
一种实现实例中，提高上行资源冲突时的MAC层优先级：
基站配置针对特定逻辑信道，允许提高UE内优先级判决时的逻辑信道优先级，可选的，指定提升到的逻辑信道优先级，如原逻辑信道优先级为3，提升为2；如不指定，可直接提升到最高逻辑信道优先级1；可选的，基站配置发生业务数据传输错误的触发条件。
终端接收基站关于UE内优先级判决时提高逻辑信道优先级的配置；根据基站配置或协议规定或自行决策，判断发生传输错误；在发生上行资源冲突时，将映射了该逻辑信道数据的MAC PDU对应上行资源的优先级按提升的优先级进行判决，以优先传输该MAC PDU。
(5)终端接收网络侧发送的第五配置信息，按照所述第五配置信息提高业务数据传输优先级，所述第五配置信息针对指定的配置资源CG，在终端在发生业务数据传输错误时，将承载在所述CG对应的物理层优先级设置为高优先级；
该实施例中，后续当发生多个上行资源冲突时，优先传包含该逻辑信道数据的上行资源。针对物理层UE内优先级方案，基站配置针对指定的CG， 在终端发生传输错误时，可以提高优先级参数phy-PriorityIndex(将p0提升为p1)。这样，可以提高承载在该CG上的业务的传输优先级。应用于两个或多个上行传输资源冲突时，通过提高预配置资源CG的物理层优先级，可以优先传该预配置资源。
一种实现实例中，提高CG优先级：
基站针对特定CG，配置可提升物理层优先级，即将allowedPHY-PriorityIndex提升为p1；可选的，基站配置发生业务数据传输错误的触发条件。
终端接收基站关于CG物理层优先级提升的配置；根据基站配置或协议规定或自行决策，判断发生传输错误；在发生上行资源冲突时，优先传输该CG资源上的传输。
(6)终端接收网络侧发送的第六配置信息，按照所述第六配置信息提高业务数据传输优先级，所述第六配置信息允许终端在指定的逻辑信道发生业务数据传输错误时，提高所述逻辑信道对应的物理层优先级为高优先级，所述物理层优先级用于指定在上行传输资源发送冲突时，优先传高优先级的传输；
该实施例中，针对逻辑信道配置，在终端发生传输错误时，提高该逻辑信道的物理优先级allowedPHY-PriorityIndex，将p0提升为p1。应用于当两个或多个上行传输资源冲突时，优先传包含该逻辑信道数据的动态调度资源。
一种实现实例中，放松逻辑信道到物理层动态调度资源的映射：
基站针对逻辑信道配置，在终端发生传输错误时，提高该逻辑信道的物理优先级allowedPHY-PriorityIndex，将p0提升为p1，或规定可以映射到任意物理层调度信令指示的动态调度资源上(即只要有动态调度资源就映射，不区分p0还是p1指示)；可选的，基站配置发生业务数据传输错误的触发条件。
终端接收基站关于放松逻辑信道到动态调度资源映射的配置；根据基站配置或协议规定或自行决策，判断发生传输错误；
将该逻辑信道的数据优先在高优先级动态调度资源上传输，可选的，根据基站配置，如果当前时刻基站只分配了低优先级动态调度资源且没有上行 资源冲突，该逻辑信道数据可以映射到该低优先级动态调度资源上。
(7)终端接收网络侧为预设逻辑信道配置的至少两套逻辑信道参数，未发生传输错误时，使用所述至少两套逻辑信道参数中的优先级更低的逻辑信道配置参数；当终端发生业务数据传输错误时，使用所述至少两套逻辑信道参数中的优先级更高的逻辑信道配置参数进行传输。
该实施例中，基站为特定逻辑信道配置两套逻辑信道参数，当终端发生传输错误时，后续传输使用优先级更高的逻辑信道配置参数。
一种实现实例中，配置两套逻辑信道参数：
基站针对特定逻辑信道，配置两套逻辑信道参数；可选的，基站配置发生业务数据传输错误的判断标准。
终端接收基站针对特定逻辑信道的两套逻辑信道参数；根据基站配置或协议规定或自行决策，判断发生传输错误；采用基站配置的更高优先级的逻辑信道参数进行后续数据传输。
