Abstract

本申请实施例提供一种通知发送时间信息的方法及其装置，所述方法包括：终端设备在高层确定业务数据或控制信息的传输所对应的发送时间信息；所述终端设备从所述高层向物理层(PHY)发送所述发送时间信息。

Description

通知发送时间信息的方法以及装置 技术领域
本申请实施例涉及通信技术领域。
背景技术
汽车通信业务，以V2X(车对万物，Vehicle-to-Everything)业务表示，可以包括多种类型：V2V(车对车通信，Vehicle-to-Vehicle)、V2I(车对基础设施通信，Vehicle-to-Infrastructure)和V2P(车对人通信，Vehicle-to-Pedestrian)。V2X业务可以通过PC5接口和/或Uu接口提供。对通过PC5接口传输的V2X业务，由V2X sidelink通信提供，它是一种终端能直接通过PC5接口彼此通信的通信模式。LTE(长期演进，Long Term Evolution)或NR(新无线，New Radio)中，终端在网络的覆盖之内或覆盖之外时，都支持这个通信模式。
V2X中有两种资源分配方式，分别为模式1(mode-1)和模式2(mode-2)。其中mode-1是指网络设备调度边链路资源的资源分配方式，mode-2是指终端设备自主选择资源的资源分配方式。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现，在3GPP(第三代合作伙伴计划，3rd Generation Partnership Project)中同意，在sidelink资源分配mode-2中，对于终端而言，高层可以请求物理层确定一个子集的资源，高层将从中选择用于PSSCH(物理边链路共享信道，Physical Sidelink Shared Channel)或PSCCH(物理边链路控制信道，Physical Sidelink Control Channel)的传输(transmission)的资源，其中PSSCH信道承载业务数据，PSSCH的传输为业务数据的传输，PSCCH信道承载控制信息，PSCCH的传输为控制信息的传输。为了触发这个过程，在某一时间单元(例如时隙(slot)n)中，高层为此PSSCH/PSCCH的传输提供一些参数给物理层，其中包括发送时间信息，例如剩余的分组包延迟预算 (the remaining packet delay budget，the remaining PDB)。然而，高层如何确定并向物理层提供上述参数，目前还没有解决方法。
针对上述问题的至少之一，本申请实施例提供一种通知发送时间信息的方法以及装置。
根据本申请实施例的一方面，提供一种通知发送时间信息的方法，包括：
终端设备在高层确定业务数据或控制信息的传输(transmission)所对应的发送时间信息；
所述终端设备从所述高层向物理层(PHY)发送所述发送时间信息。
根据本申请实施例的另一方面，提供一种通知发送时间信息的装置，配置于终端设备，其中，所述装置包括：
确定单元，其在所述终端设备的高层确定业务数据或控制信息的传输所对应的发送时间信息；
发送单元，其从所述终端设备的所述高层向物理层(PHY)发送所述发送时间信息。
根据本申请实施例的再一方面，提供一种配置方法，包括：
网络设备生成配置信息，所述配置信息指示逻辑信道对应的第一时间信息和/或MAC CE对应的第二时间信息；
所述网络设备向终端设备发送所述配置信息，所述终端设备根据所述配置信息确定业务数据或控制信息的传输对应的发送时间信息，从而从高层向物理层指示所述发送时间信息。
根据本申请实施例的又一方面，提供一种配置装置，配置于网络设备，所述配置装置包括：
生成单元，其生成配置信息，所述配置信息指示逻辑信道对应的第一时间信息和/或MAC CE对应的第二时间信息；
发送单元，其向终端设备发送所述配置信息，所述终端设备根据所述配置信息确定业务数据或控制信息的传输对应的发送时间信息，从而从高层向物理层指示所述发送时间信息。
根据本申请实施例的又一方面，提供一种配置方法，包括：
第二终端设备生成配置信息或指示信息，所述配置信息或指示信息指示逻辑信道 对应的第一时间信息和/或MAC CE对应的第二时间信息；
所述第二终端设备向与其进行边链路通信的第一终端设备发送所述配置信息或指示信息，所述第一终端设备根据所述配置信息或指示信息确定业务数据或控制信息的传输对应的发送时间信息，从而从高层向物理层指示所述发送时间信息。
根据本申请实施例的又一方面，提供一种配置装置，配置于第二终端设备，所述配置装置包括：
生成单元，其生成配置信息或指示信息，所述配置信息或指示信息指示逻辑信道对应的第一时间信息和/或MAC CE对应的第二时间信息；
发送单元，其向与所述第二终端设备进行边链路通信的第一终端设备发送所述配置信息或指示信息，所述第一终端设备根据所述配置信息或指示信息确定业务数据或控制信息的传输对应的发送时间信息，从而从高层向物理层指示所述发送时间信息。
本申请实施例的有益效果之一在于：根据本申请实施例，能够实现高层对物理层通知PSSCH/PSCCH的传输对应的发送时间(例如剩余时延预算)的要求，有助于物理层进行合适的候选资源选择，以满足业务数据和/或控制信息对应的时延要求，此外对现有LTE和NR规范影响较小，实现复杂度低。

下面结合附图对本申请实施例的各个实施方式进行说明。
第一方面的实施例
本申请实施例提供一种通知发送时间信息的方法，从终端设备侧进行说明。图2是本申请实施例的通知发送时间信息的方法的一个示意图，如图2所示，该方法包括：
201，终端设备在高层确定业务数据或控制信息的传输(transmission)所对应的发送时间信息；

根据本申请实施例，能够实现高层对物理层通知PSSCH/PSCCH的传输对应的发送时间的要求，例如剩余时延预算的要求，有助于物理层进行合适的候选资源选择，以满足业务数据和/或控制信息对应的时延要求，此外对现有LTE和NR规范影响较小，实现复杂度低。
在一些实施例中，高层可以是终端设备的介质访问控制(MAC)层，也可以是终端设备的无线资源控制(RRC)层。
在一些实施例中，业务数据例如为PSSCH信道承载的数据，业务数据的传输所对应的发送时间信息是指：该PSSCH信道承载的数据的传输(transmission)所对应的发送时间信息，可以是介质访问控制协议数据单元(MAC PDU)或传输块(TB)或边链路共享信道(SL-SCH)对应的发送时间信息；控制信息例如为PSCCH信道承载的控制信息，例如边链路控制信息SCI(sidelink control information)，控制信息的传输所对应的发送时间信息是指：该PSCCH信道承载的控制信息对应的MAC PDU或TB或SL-SCH对应的发送时间信息，例如PSCCH中承载的SCI指示对应的PSSCH的时频资源和参数信息等，该PSSCH信道承载MAC PDU或TB或SL-SCH数据，通过此方式，控制信息与MAC PDU或TB或SL-SCH对应。
在一些实施例中，业务数据例如为PSSCH信道将要承载的数据，业务数据的传输所对应的发送时间信息是指：该PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息，可以是逻辑信道的数据对应的时间信息(称为第一时间信息)或MAC CE对应的时间信息(称为第二时间信息)。
在一些实施例中，上述发送时间信息或第一时间信息或第二时间信息例如为分组包延迟预算(Packet Delay Budget，PDB)，或者剩余的分组包延迟预算(the remaining PDB)，或者时延信息(latency information)，或者以上任意组合。并且，这里的PDB或剩余的PDB的单位可以是毫秒，时延信息例如为时延上限或者时间窗或者定时器 等，单位可以是毫秒或子帧或时隙，本申请不限于此。
以业务数据为PSSCH信道将要承载的数据为例。
在一些实施例中，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是：逻辑信道对应的第一时间信息和/或MAC CE对应的第二时间信息中值最小的时间。
在一些实施例中，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是：逻辑信道对应的第一时间信息和/或MAC CE对应的第二时间信息中，优先级最高的逻辑信道对应的第一时间信息，或优先级最高的MAC CE对应的第二时间信息，这里，逻辑信道的优先级为网络设备配置的逻辑信道优先级，优先级的值越低表示优先级越高，MAC CE的优先级为资源分配的优先级(例如是逻辑信道优先级处理过程中的优先级)，可以是预定义的或网络设备配置的。
在一些实施例中，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是：逻辑信道对应的第一时间信息和/或MAC CE对应的第二时间信息中，优先级最高的逻辑信道对应的第一时间信息，或优先级最高的MAC CE对应的第二时间信息，这里，逻辑信道的优先级为网络设备配置的逻辑信道优先级，优先级的值越低表示优先级越高，MAC CE的优先级为高层指示给物理层的优先级或者物理层中的处理所使用的优先级，可以是预定义的或网络设备配置的，也可以是一个固定值，优先级的值越高表示优先级越低或者优先级的值越低表示优先级越低。
在一些实施例中，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是：逻辑信道对应的第一时间信息和/或MAC CE对应的第二时间信息中值最大的时间，或者还可以是逻辑信道对应的第一时间信息和/或MAC CE对应的第二时间信息的平均时间。
在一些实施例中，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是逻辑信道对应的第一时间信息。即，可以不考虑MAC CE对应的第二时间信息。
在一些实施例中，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是MAC CE对应的第二时间信息。即，可以不考虑逻辑信道对应的第一时间信息。
在一些实施例中，上述逻辑信道可以是V2X载波上允许的逻辑信道。例如，一 个逻辑信道或者该逻辑信道对应的业务或业务类型与载波之间的对应关系可以由网络配置(例如通过系统信息或专用RRC信令)或者被预配置或者被PC5对端UE配置(例如通过PC5-RRC消息配置)。
在一些实施例中，上述逻辑信道可以是有数据待发送的逻辑信道和/或令牌桶(Bj)的值大于0的逻辑信道，上述MAC CE可以是被触发的MAC CE或者等待发送的MAC CE，也即，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息，可以是有数据待发送的逻辑信道和/或Bj(令牌桶)值大于0的逻辑信道对应的第一时间信息或者是被触发或等待发送的MAC CE对应的第二时间信息。
在这些实施例中，可能没有或者有一个或多于一个逻辑信道有边链路数据待发送(sidelink data available)和/或对应的Bj值大于0，也可能没有或者有一个或多于一个MAC CE(例如CSI report MAC CE)被触发或等待发送，也可能既有一个或多于一个逻辑信道有边链路数据待发送和/或对应的Bj值大于0，又有一个或多于一个MAC CE(例如CSI report MAC CE)被触发或等待发送。
以上述逻辑信道是有数据待发送的逻辑信道，上述MAC CE是被触发的MAC CE为例。
例如，如果仅有一个逻辑信道有数据待发送(且没有MAC CE被触发)，则上述PSSCH信道将要承载的数据传输所对应的发送时间信息是该逻辑信道对应的第一时间信息；如果仅有一个MAC CE被触发(且没有逻辑信道有数据待发送)，则上述PSSCH信道将要承载的数据传输所对应的发送时间信息是这个MAC CE对应的第二时间信息。

如果有多于一个逻辑信道有数据待发送，则上述PSSCH信道将要承载的数据传输所对应的发送时间信息是这些逻辑信道对应的第一时间信息中值最小的时间；如果有多于一个MAC CE被触发，则上述PSSCH信道将要承载的数据传输所对应的发送时间信息是这些MAC CE对应的第二时间信息中值最小的时间；如果既有逻辑信道有数据待发送，也有MAC CE被触发，则上述PSSCH信道将要承载的数据传输所对应的发送时间信息是该一个或多于一个逻辑信道对应的第一时间信息和该一个或多 于一个MAC CE对应的第二时间信息中值最小的时间。
再例如，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是：有数据待发送的逻辑信道对应的第一时间信息和/或触发的MAC CE对应的第二时间信息中，优先级最高的逻辑信道对应的第一时间信息，或优先级最高的MAC CE对应的第二时间信息，这里，逻辑信道的优先级为网络设备配置的逻辑信道优先级，优先级的值越低表示优先级越高，MAC CE的优先级为资源分配的优先级(例如是逻辑信道优先级处理过程中的优先级，例如MAC CE的优先级高于边链路数据逻辑信道的优先级且低于PC5-RRC/Signalling对应的逻辑信道的优先级)，可以是预定义的或网络设备配置的。
如果有多于一个逻辑信道有数据待发送，则上述PSSCH信道将要承载的数据传输所对应的发送时间信息是这些逻辑信道中优先级最高的逻辑信道对应的第一时间信息中值最小的时间；如果有多于一个MAC CE被触发，则上述PSSCH信道将要承载的数据传输所对应的发送时间信息是这些MAC CE中优先级最高的MAC CE对应的第二时间信息中值最小的时间；如果既有逻辑信道有数据待发送，也有MAC CE被触发，如果一个逻辑信道的优先级高于其他逻辑信道的优先级和MAC CE的优先级，则上述PSSCH信道将要承载的数据传输所对应的发送时间信息是该优先级最高的逻辑信道对应的第一时间信息，如果一个MAC CE的优先级高于逻辑信道的优先级或者如果一个MAC CE的优先级高于其他MAC CE和逻辑信道的优先级，则上述PSSCH信道将要承载的数据传输所对应的发送时间信息是该优先级最高的MAC CE对应的第二时间信息。
如果多于一个逻辑信道具有相同的最高优先级或者多于一个MAC CE具有相同的最高优先级或者逻辑信道与MAC CE具有相同的最高优先级，则上述PSSCH信道将要承载的数据传输所对应的发送时间信息可以是优先级最高的其中一个逻辑信道对应的第一时间信息或优先级最高的其中一个MAC CE对应的第二时间信息。
再例如，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是：有数据待发送的逻辑信道对应的第一时间信息和/或触发的MAC CE对应的第二时间信息中，优先级最高的逻辑信道对应的第一时间信息，或优先级最高的MAC CE对应的第二时间信息，这里，逻辑信道的优先级为网络设备配置的逻辑信道优先级，优先级的值越低表示优先级越高，MAC CE的优先级为高层指示给 物理层的优先级或者物理层中的处理所使用的优先级，可以是预定义的或网络设备配置的，也可以是一个固定值，优先级的值越高表示优先级越低或者优先级的值越低表示优先级越低。
如果有多于一个逻辑信道有数据待发送，则上述PSSCH信道将要承载的数据传输所对应的发送时间信息是这些逻辑信道中优先级最高的逻辑信道对应的第一时间信息中值最小的时间；如果有多于一个MAC CE被触发，则上述PSSCH信道将要承载的数据传输所对应的发送时间信息是这些MAC CE中优先级最高的MAC CE对应的第二时间信息中值最小的时间；如果既有逻辑信道有数据待发送，也有MAC CE被触发，如果一个逻辑信道的优先级高于其他逻辑信道的优先级和MAC CE的优先级，则上述PSSCH信道将要承载的数据传输所对应的发送时间信息是该优先级最高的逻辑信道对应的第一时间信息，如果一个MAC CE的优先级高于逻辑信道的优先级或者如果一个MAC CE的优先级高于其他MAC CE和逻辑信道的优先级，则上述PSSCH信道将要承载的数据传输所对应的发送时间信息是该优先级最高的MAC CE对应的第二时间信息。

再例如，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是：有数据待发送的逻辑信道对应的第一时间信息和/或触发的MAC CE对应的第二时间信息中值最大的时间，或者还可以是有数据待发送的逻辑信道对应的第一时间信息和/或触发的MAC CE对应的第二时间信息的平均时间，等等。
在一些实施例中，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是有数据待发送的逻辑信道对应的第一时间信息。即，可以不考虑MAC CE对应的第二时间信息。
在一些实施例中，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是被触发的MAC CE对应的第二时间信息。即，可以不考虑逻辑信道对应的第一时间信息。
在一些实施例中，上述PSSCH信道将要承载的数据的传输(transmission)所对 应的发送时间信息可以是有数据待发送的逻辑信道中待发送的数据量最多的逻辑信道对应的第一时间信息。
在一些实施例中，不同的逻辑信道或MAC CE可能对应一个或多于一个的目的地址(destination ID或destination L2 ID或destination L1 ID)，则上述逻辑信道或MAC CE可以是某个目的地址(称为第一目的地址)对应的逻辑信道或MAC CE，也即，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是，第一目的地址对应的逻辑信道对应的第一时间信息或MAC CE对应的第二时间信息。
上述第一目的地址可以是：具有最高优先级的逻辑信道或MAC CE对应的目的地址，或者是具有最高优先级的逻辑信道的目的地址(不考虑MAC CE的优先级)，或者是一个逻辑信道对应的目的地址，或者是一个MAC CE对应的目的地址，或者是第一时间信息中值最小的第一时间信息对应的逻辑信道对应的目的地址，或者是第二时间信息中值最小的第二时间信息对应的MAC CE对应的目的地址，或者是第一时间信息和第二时间信息中值最小的第一时间信息对应的逻辑信道对应的目的地址或第二时间信息对应的MAC CE对应的的目的地址，等等。
在这些实施例中，逻辑信道还可以是有数据待发送和/或Bj值大于0的逻辑信道，MAC CE还可以是触发的或等待发送的MAC CE。
在这些实施例中，逻辑信道的优先级可以是网络配置的逻辑信道优先级，MAC CE的优先级可以是逻辑信道优先级处理过程中资源分配中的优先级，例如MAC CE的优先级高于边链路数据逻辑信道的优先级且低于PC5-RRC/Signalling对应的逻辑信道的优先级，MAC CE的优先级也可以是网络配置的或预定义的优先级。
图3是目的地址和逻辑信道或MAC CE之间的对应关系的一个示意图，示出了上述第一目的地址是最高优先级的逻辑信道或MAC CE对应的目的地址的情况，下面结合图3对该情况进行说明。
终端设备可能进行针对多于一个目的地址(destination ID或destination L2 ID或destination L1 ID等)的边链路数据传输，如图3所示，终端设备具有4个逻辑信道LCH1-LCH4，其中LCH1和LCH2对应于目的地址1，LCH3和LCH4对应于目的地址2，LCH1的优先级值为4，LCH2的优先级值为0，LCH3的优先级值为1，LCH4的优先级值为2，MAC CE1的优先级值为1，MAC CE2的优先级值为1，假设优先 级的值越低代表优先级越高。
其中，终端设备首先选择具有最高优先级的逻辑信道或MAC CE的目的地址，在图3中，LCH2的优先级最高(优先级值0)，LCH2所在的目的地址是destination ID1；由于destination ID1对应的LCH和MAC CE为LCH1、LCH2和MAC CE1，因此PSSCH信道将要承载的数据的传输所对应的发送时间信息是LCH1或LCH2对应的第一时间信息或MAC CE1对应的第二时间信息。
图4是目的地址和逻辑信道或MAC CE之间的对应关系的另一个示意图，示出了上述第一目的地址是最高优先级的逻辑信道对应的目的地址的情况，也即不考虑MAC CE，下面结合图4对该情况进行说明。
终端设备首先选择具有最高优先级的逻辑信道的目的地址，在图4中，假设不考虑MAC CE的优先级，具有最高优先级的逻辑信道为LCH3(优先级值为2)。LCH3所在的目的地址为destination ID2，destination ID2对应的逻辑信道和MAC CE为LCH3、LCH4和MAC CE2。因此PSSCH信道将要承载的数据的传输所对应的发送时间信息是LCH3或LCH4对应的第一时间信息或MAC CE2对应的第二时间信息。
例如，上述PSSCH信道将要承载的数据的传输所对应的发送时间信息可以是第一目的地址对应的逻辑信道对应的第一时间信息和/或MAC CE对应的第二时间信息中值最小的时间。
以图3为例，LCH2的优先级最高(优先级值0)，LCH2所在的目的地址是destination ID1，destination ID1对应的LCH和MAC CE为LCH1、LCH2和MAC CE1，其中MAC CE1对应的第二时间信息(时延信息为2ms)值最小，因此PSSCH信道将要承载的数据的传输所对应的发送时间信息是MAC CE1对应的第二时间信息，即2ms。
再例如，上述PSSCH信道将要承载的数据的传输所对应的发送时间信息可以是：第一目的地址对应的逻辑信道对应的第一时间信息和/或MAC CE对应的第二时间信息中，优先级最高的逻辑信道对应的第一时间信息，或优先级最高的MAC CE对应的第二时间信息，这里，逻辑信道的优先级为网络设备配置的逻辑信道优先级，优先级的值越低表示优先级越高，MAC CE的优先级为资源分配的优先级(例如是逻辑信道优先级处理过程中的优先级)，可以是预定义的或网络设备配置的。
以图3为例，LCH2的优先级最高(优先级值0)，LCH2所在的目的地址是 destination ID1，destination ID1对应的LCH和MAC CE为LCH1、LCH2和MAC CE1，其中LCH2的优先级最高(优先级值为0)，因此PSSCH信道将要承载的数据的传输所对应的发送时间信息是LCH2对应的第一时间信息，即20ms。
再例如，上述PSSCH信道将要承载的数据的传输所对应的发送时间信息可以是：第一目的地址对应的逻辑信道对应的第一时间信息和/或MAC CE对应的第二时间信息中，优先级最高的逻辑信道对应的第一时间信息，或优先级最高的MAC CE对应的第二时间信息，这里，逻辑信道的优先级为网络设备配置的逻辑信道优先级，优先级的值越低表示优先级越高，MAC CE的优先级为高层指示给物理层的优先级或者物理层中的处理所使用的优先级，可以是预定义的或网络设备配置的，也可以是一个固定值，优先级的值越高表示优先级越低或者优先级的值越低表示优先级越低。
再例如，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是：第一目的地址对应的逻辑信道对应的第一时间信息和/或MAC CE对应的第二时间信息中值最大的时间，或者还可以是第一目的地址对应的逻辑信道对应的第一时间信息和/或MAC CE对应的第二时间信息的平均时间。
再例如，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是第一目的地址对应的逻辑信道对应的第一时间信息。即，可以不考虑第一目的地址对应的MAC CE对应的第二时间信息。
再例如，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是第一目的地址对应的MAC CE对应的第二时间信息。即，可以不考虑第一目的地址对应的逻辑信道对应的第一时间信息。
再例如，上述PSSCH信道将要承载的数据的传输(transmission)所对应的发送时间信息可以是第一目的地址对应的有数据待发送的逻辑信道中待发送的数据量最多的逻辑信道对应的第一时间信息。
以业务数据为PSSCH信道承载的数据，而控制信息为PSCCH信道承载的控制信息为例。
在一些实施例中，上述MAC PDU或TB或SL-SCH对应的发送时间信息是该MAC PDU或TB或SL-SCH中包括的逻辑信道(LCH)对应的时间信息(称为第一时间信息)或MAC CE对应的时间信息(称为第二时间信息)。也即，上述MAC PDU或TB或SL-SCH对应的发送时间信息即为这里的第一时间信息或第二时间信息。关 于第一时间信息和第二时间信息的含义已经在前面做了说明，此处省略说明。
在这些实施例中，该MAC PDU或TB或SL-SCH中可能不包含逻辑信道数据或包括一个逻辑信道的数据或包括多于一个逻辑信道的数据，可能不包含MAC CE或包含一个或多于一个MAC CE，也就是说，该MAC PDU或TB或SL-SCH可能仅包含一个或多于一个逻辑信道的数据，或者仅包含一个或多于一个MAC CE，或者既包含一个或多于一个逻辑信道的数据也包含一个或多于一个MAC CE。
例如，上述MAC PDU或TB或SL-SCH对应的发送时间信息可以是：该MAC PDU或TB或SL-SCH中包括的逻辑信道对应的第一时间信息和/或MAC CE对应的第二时间信息中值最小的时间。
以MAC PDU为例，如果该MAC PDU仅包含一个逻辑信道的数据，则该MAC PDU对应的发送时间信息是该MAC PDU中包括的这个逻辑信道对应的第一时间信息；如果该MAC PDU仅包含多于一个逻辑信道的数据，则该MAC PDU对应的发送时间信息是该MAC PDU中包括的多于一个逻辑信道对应的第一时间信息中值最小的时间；如果该MAC PDU仅包含一个MAC CE，则该MAC PDU对应的发送时间信息是该MAC PDU中包括该MAC CE对应的第二时间信息；如果该MAC PDU仅包含多于一个MAC CE，则该MAC PDU对应的发送时间信息是该MAC PDU中包括的多于一个MAC CE对应的第二时间信息中值最小的时间；如果该MAC PDU既包含一个或多于一个逻辑信道的数据也包含一个或多于一个MAC CE，则该MAC PDU对应的发送时间信息是该MAC PDU中包括的一个或多于一个逻辑信道对应的第一时间信息和一个或多于一个MAC CE对应的第二时间信息中值最小的时间。
再例如，上述MAC PDU或TB或SL-SCH对应的发送时间信息可以是：该MAC PDU或TB或SL-SCH中包括的逻辑信道和/或MAC CE中，优先级最高的逻辑信道对应的第一时间信息，或优先级最高的MAC CE对应的第二时间信息，这里，逻辑信道的优先级为网络设备配置的逻辑信道优先级，优先级的值越低表示优先级越高，MAC CE的优先级为资源分配的优先级，可以是预定义的或网络设备配置的。
