Abstract

本申请实施例提供一种数据发送方法，资源配置方法以及装置；该方法包括：高层确定触发资源选择或资源重选时，从所述高层向物理层提供指示信息，所述指示信息用于指示与HARQ传输相关的信息；至少根据所述指示信息选择用于发送边链路数据的资源；在选择的资源上发送所述边链路数据。

Description

数据发送方法，资源配置方法以及装置 技术领域
本申请实施例涉及通信技术领域。
背景技术
在Rel-15以及之前版本的车联网(V2X)通信中，支持边链路(Sidelink)资源的两种分配方式：Mode 1和Mode 2。对于Mode 1，边链路资源由网络设备(例如基站)进行分配而获得；对于Mode 2，终端设备自主地选择发送资源，即发送资源通过感知(sensing)或检测-资源选择过程获得。
另一方面，新无线(NR，New Radio)V2X是目前Rel-16标准化的研究项目之一，相比于长期演进(LTE，Long Term Evolution)V2X，NR V2X需要支持诸多新场景和新业务(例如远程驾驶、自动驾驶和车队行驶等)，需要满足更高的技术指标(高可靠、低时延、高数据速率等)。
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：相比于LTE V2X，在NR V2X中需要支持更多的重传次数，即重传次数可能大于一次，总的发送(初传加上重传)次数可能大于2(例如最大可以配置为32)。此外，NR V2X相比于LTE V2X，需要额外地支持混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)确认(ACK)反馈机制，因此在资源选择过程中会有额外的时间限制，如果仍然使用现有的资源选择方法，则可能会导致选择出的资源无法满足一个传输块的目标发送次数的问题。
针对上述问题的至少之一，本申请实施例提供一种数据发方法，资源配置方法及装置。
根据本申请实施例的一个方面，提供一种数据发送方法，应用于终端设备，包括：
终端设备在高层确定触发资源选择或资源重选时，从该高层向物理层提供指示信 息，该指示信息用于指示与HARQ传输相关的信息；
该终端设备至少根据该指示信息选择用于发送边链路数据的资源；
该终端设备在选择的资源上发送该边链路数据。
根据本申请实施例的另一个方面，提供一种数据发送装置，应用于终端设备，包括：
处理单元，其用于在高层确定触发资源选择或资源重选时，从该高层向物理层提供指示信息，该指示信息用于指示与HARQ传输相关的信息；
选择单元，其用于至少根据该指示信息选择用于发送边链路数据的资源；
发送单元，其用于在该选择单元选择的资源上发送该边链路数据。
根据本申请实施例的另一个方面，提供一种数据发送方法，应用于终端设备，包括：
终端设备获取资源池配置信息，该资源池配置信息包括候选时间资源单位数量的最小值参数信息，该最小值参数信息包括至少一个与HARQ传输相关的信息对应的最小值；
该终端设备至少根据该最小值参数信息选择候选时域资源，该候选时域资源包括第一数量个时间资源单位，并从该候选时域资源中选择资源用于边链路数据发送；
该终端设备在选择的资源上发送该边链路数据。
根据本申请实施例的另一个方面，提供一种数据发送装置，应用于终端设备，包括：
获取单元，其用于获取资源池配置信息，该资源池配置信息包括候选时间资源单位数量的最小值参数信息，该最小值参数信息包括至少一个与HARQ传输相关的信息对应的最小值；
选择单元，其用于至少根据该最小值参数信息选择候选时域资源，该候选时域资源包括第一数量个时间资源单位，并从该候选时域资源中选择资源用于边链路数据发送；
发送单元，其用于在该选择单元选择的资源上发送该边链路数据。
根据本申请实施例的另一个方面，提供一种资源配置方法，应用于网络设备，包括：
网络设备配置资源池配置信息，该资源池配置信息包括候选时间资源单位数量的 最小值参数信息，该最小值参数信息包括至少一个与HARQ传输相关的信息对应的最小值；
该网络设备将该资源池配置信息发送给终端设备。
根据本申请实施例的另一个方面，提供一种资源配置装置，应用于网络设备，包括：
配置单元，其用于配置资源池配置信息，该资源池配置信息包括候选时间资源单位数量的最小值参数信息，该最小值参数信息包括至少一个与HARQ传输相关的信息对应的最小值；
发送单元，其用于将该资源池配置信息发送给终端设备。
本申请实施例的有益效果之一在于：高层向物理层指示与HARQ传输有关的信息或终端设备获取候选时间资源单位数量的最小值参数信息，该最小值参数信息包括至少一个与HARQ传输相关的信息对应的最小值；以便物理层根据上述信息选择发送边链路数据的资源，由此使得选择出的资源满足待发数据目标发送次数的需求，保证待发数据的可靠性需求。

以下通过示例对本申请实施例的场景进行说明，但本申请不限于此。
图1是本申请实施例的通信系统的示意图，示意性说明了以终端设备和网络设备为例的情况，如图1所示，通信系统100可以包括网络设备101和终端设备102、103。为简单起见，图1仅以两个终端设备和一个网络设备为例进行说明，但本申请实施例不限于此。
在本申请实施例中，网络设备101和终端设备102、103之间可以进行现有的业务或者未来可实施的业务发送。例如，这些业务可以包括但不限于：增强的移动宽带(eMBB，enhanced Mobile Broadband)、大规模机器类型通信(mMTC，massive Machine Type Communication)和高可靠低时延通信(URLLC，Ultra-Reliable and Low-Latency Communication)，等等。
值得注意的是，图1示出了两个终端设备102、103均处于网络设备101的覆盖范围内，但本申请不限于此。两个终端设备102、103可以均不在网络设备101的覆盖范围内，或者一个终端设备102在网络设备101的覆盖范围之内而另一个终端设备103在网络设备101的覆盖范围之外。
在本申请实施例中，两个终端设备102、103之间可以进行边链路发送。例如，两个终端设备102、103可以都在网络设备101的覆盖范围之内进行边链路发送以实现V2X通信，也可以都在网络设备101的覆盖范围之外进行边链路发送以实现V2X通信，还可以一个终端设备102在网络设备101的覆盖范围之内而另一个终端设备103在网络设备101的覆盖范围之外进行边链路发送以实现V2X通信。
在本申请实施例中，终端设备102和/或103可以自主选择边链路资源(即采用Mode 2)，在这种情况下边链路发送可以与网络设备101无关，即网络设备101是可选的。当然，本申请实施例也可以将自主选择边链路资源(即采用Mode 2)和由网 络设备分配边链路资源(即采用Mode 1)结合起来；本申请实施例不对此进行限制。
在LTE V2X中，终端设备能够通过感知检测+资源选择的过程来获得边链路发送资源，其中可以持续不断地进行感知(sensing)来获得资源池内资源的占用情况。例如，终端设备可以根据前一段时间内(称为感知窗)的资源占用情况来估计后一段时间内(称为选择窗)的资源占用情况。
图2是终端设备进行边链路资源选择的一示意图，如图2所示，终端设备例如通过第(n-1000)至第(n-1)个子帧或时隙(即感知窗，sensing window)内的边链路控制信息(SCI，Sidelink Control Information)和对不同位置时频资源参考信号的检测，可以获得该感知窗的资源占用情况，进而可以估计出第(n+T1)至第(n+T2)个子帧或时隙(即选择窗，selection window)的资源占用情况。
例如，步骤1-物理层获得候选资源集合：
当有待发送的边链路数据时，终端设备的物理层从高层(例如介质访问控制(MAC，Media Access Control)层)获得资源选择的粒度R x,y；该粒度可以表示一个子帧内的一系列连续的子信道，每个子信道包括多于一个的连续物理资源块(PRB，Physical Resource Block)，PRB个数可以由资源池决定，资源池由网络设备(例如基站)配置或预配置；整个选择窗中的所有子帧内R x,y大小的资源(以下简称为R x,y候选资源)的集合被初始化定义为Set A。
终端设备可以根据在待发送数据到达之前在该感知窗内进行检测的结果，排除Set A中的部分候选资源。例如，以下的R x,y候选资源需要被排除：
——终端设备在感知窗内的发送子帧所对应的在选择窗中可能被进行资源预留的子帧内的所有R x,y候选资源；
——终端设备在感知窗内进行检测的子帧中的某个R x,y候选资源，其中在该R x,y候选资源上检测到SCI预留了当前选择窗内对应的子帧，且指示的频域资源与这个R x,y候选资源在频域上有重合，且该SCI对应的物理边链路共享信道(PSSCH，Physical Sidelink Shared Channel)的参考信号接收功率(RSRP，Reference Signal Receiving Power)的检测结果大于一个门限值(以下称为RSRP门限值)；或者，该SCI预留了选择窗之后的子帧，且该子帧与当前选择窗内子帧可能预留的后续子帧中的一个子帧在时域是同一个子帧，且频域资源与该R x,y候选资源在频域上有重合，且该SCI对应的PSSCH的RSRP的检测结果大于RSRP门限值。
如果经过了上面的资源排除之后，Set A中所剩余的R x,y候选资源个数不足初始总数的20％，则将该RSRP门限值增大3dB，从初始的Set A中重新进行排除，直到Set A中剩余的R x,y候选资源个数大于或等于初始总数的20％为止。
将Set A中的R x,y候选资源按照S-RSSI由小到大的顺序放入Set B，直到Set B中的R x,y候选资源的个数大于或等于Set A中的R x,y候选资源初始总数的20％；其中，Set B是一个初始为空的集合，S-RSSI表示R x,y候选资源中所有子信道的信号强度的线性平均值。
步骤2-MAC层在候选资源集合中选择资源：
即终端设备的物理层可以将Set B上报给MAC层，MAC层在Set B中进行随机选择，选择一个候选资源进行数据发送。此外，在指示的资源中选择一个解调和编码方案(MCS，Modulation and Coding Scheme)进行数据发送。
如果在资源选择之前MAC层配置了重传，则MAC层在选择了一个资源后，再在剩余可用资源集合且满足初传SCI可指示的时域范围(例如[-15,15]个子帧)内包含的资源中，随机选择一个资源，并且在指示的资源中选择一个MCS进行数据重传。两个资源时间上在前的用来发初传资源，时间上在后的用来发重传资源。如果不存在这样的可用资源，则当前发送不支持重传，即发送次数变为1。
另外，在LTE中，还支持了一种部分感知(partial sensing)的资源选择机制，使得终端设备(例如P-UE)可以在部分子帧上进行感知，以达到省电目的，且在对应的选择窗中，基于终端设备实现，选择其中的部分子帧(以下称为Y个子帧)，从这Y个子帧中的候选资源中选择发送资源。Y的值需要大于或等于一个高层配置的最小值参数minNumCandidateSF。对应的，针对资源池(resource pool)高层配置的参数gapCandidateSensing对应的比特位图bitmap(指示Y个子帧对应的前k×100个子帧位置中哪些位置进行了感知sensing)中第k个比特被配置为1时，且如果一个子帧
Figure PCTCN2020090379-appb-000001
被包含在选择窗中所选择的Y个子帧集合当中，那么对应的子帧
Figure PCTCN2020090379-appb-000002
需要是在感知窗中对应进行了感知的子帧。换句话说只有在感知窗中进行了感知的部分子帧，其对应的选择窗中的子帧才可以被选择为Y个子帧集合中的子帧。
值得注意的是，以上仅对LTE V2X中感知检测+资源选择的过程进行了示意性说明。关于上述过程的具体内容，还可以参考3GPP TS 36.213V15.2.0中第14.1.1.6等 处的内容。
相比于LTE V2X，在NR V2X中需要支持更多的重传次数，即重传次数可能大于1，总的发送次数大于2(最大可以配置为32)。此外，NR V2X相比于LTE V2X，需要额外地支持混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)确认(ACK)反馈机制，因此，在现有的部分感知机制中会存在如下问题：
一方面，在当前的标准中，物理层进行候选资源集合选择时，高层(例如MAC层)会提供给物理层如下参数：
-the resource pool from which the resources are to be reported：资源池配置；
-L1priority,prio TX：待发数据的L1优先级；
-the remaining packet delay budget：待发数据的剩余时延预算；
-the number of sub-channels to be used for the PSSCH/PSCCH transmission in a slot,L subCH：资源选择的粒度大小
-optionally,the resource reservation interval,P rsvp_TX,in units of ms：可选的，周期业务对应的周期长度。
在NR V2X中，如果物理层仅根据上述信息在选择窗中选择Y个时间资源单位(以下在NR中以该时间资源单位是时隙为例)并进行部分感知时，所选的Y个时隙可能无法满足MAC层确定的待发数据需要进行的目标发送次数，以下结合附图3说明上述问题，如图3所示，物理层基于实现和Y的最小值参数minNumCandidateSlot配置的最小值5，选择了5个时隙作为Y个候选时隙集合，但由MAC决定的目标发送次数为6，则由于物理层不知道MAC层决定的目标发送次数信息，导致所选的Y个时隙无法满足目标发送次数的需求，无法保证待发数据的可靠性需求。
另一方面，在R-16的NR V2X中，RAN1还规定了对于多次发送的资源选择，所选择的相邻两个资源之间的间隔需要满足大于等于HARQ往返时间间隔HARQ RTT gap，其长度定义为z＝a+b，其中a等于相邻两个资源中的第一个资源的PSSCH的最后一个符号的结束时间到其对应的物理边链路反馈信道(PSFCH，Physical Sidelink Feedback Channel)接收的首个符号的开始时间(根据K和N确定，K和N的含义见第一方面实施例)；b为基于终端设备实现的一个时间段，用于PSFCH的接收和处理，以及对应PSSCH重传的准备时间(包括对应信道和生成时间和Tx-Rx/Rx-tx switching gap)。则仅根据以上信息，对于HARQ ACK使能传输，终端设备在选择Y 个时隙时，由于需要满足上述HARQ RTT gap，导致所选的Y个时隙无法满足目标发送次数的需求。以下结合附图4说明上述问题，如图4所示，物理层仍选择了5个时隙作为Y个时隙集合，由MAC决定的目标发送次数为4，对于盲重传来说，如果每个时隙中都有可用资源，候选资源能够达到目标发送次数的需求；但对于HARQ ACK使能的重传来说，会有Y个时隙中的时隙由于在上述间隔内，而被排除掉，则导致不能满足目标发送次数的需求，无法保证待发数据的可靠性需求。
本申请的以下实施例针对上述问题的一个或多个提出相应解决方案。
在本申请实施例中，以V2X为例对边链路进行说明，但本申请不限于此，还可以适用于V2X以外的边链路发送场景。此外，边链路控制信息(SCI，Sidelink Control Information)由PSCCH承载，边链路数据由PSSCH承载，边链路反馈信息由物理边链路反馈信道(PSFCH，Physical Sidelink Feedback Channel)承载。
在以下的说明中，在不引起混淆的情况下，术语“边链路”和“V2X”可以互换，术语“PSFCH”和“边链路反馈信道”可以互换，术语“PSCCH”和“边链路控制信道”或“边链路控制信息”可以互换，术语“PSSCH”和“边链路数据信道”或“边链路数据”也可以互换。
另外，发送(transmitting)或接收(receiving)PSSCH可以理解为发送或接收由PSSCH承载的边链路数据；发送或接收PSFCH可以理解为发送或接收由PSFCH承载的边链路反馈信息。至少一次发送(transmission，也可称为传输)可以理解为至少一次PSSCH/PSCCH发送或者至少一次边链路数据/信息发送，当前发送可以理解为当前PSSCH/PSCCH发送或者当前边链路数据/信息发送。
在本申请实施例中，初始选择是相对于重选而言的，并不能理解为特定的哪次选择。例如可以将第1次选择称为初始选择，将第2次选择称为重选；也可以将第n次选择称为初始选择，将第n+1次选择称为重选；本申请实施例对此不进行限制。
第一方面的实施例
本申请实施例提供一种数据发送方法，从终端设备进行说明。其中该终端设备(可称为发送终端设备)作为业务数据的发送方，向一个或多个其他终端设备(可称为接收终端设备)发送边链路数据。
图5是本申请实施例的数据发送方法的一示意图，如图5所示，该方法包括：
501，在高层确定触发资源选择或资源重选时，从该高层向物理层提供指示信息，该指示信息用于指示与HARQ传输相关的信息；
502，至少根据该指示信息选择用于发送边链路数据的资源；
503，在选择的资源上发送该边链路数据。
在本申请实施例中，终端设备中的高层可以向物理层指示与HARQ传输有关的信息，由此使得选择出的资源满足待发数据目标发送次数的需求，保证待发数据的可靠性需求。
值得注意的是，以上附图5仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图5的记载。
在一些实施例中，终端设备的高层可以是MAC层，在满足预定条件下，MAC层可以触发资源选择或资源重选；满足预定条件包括：在MAC层被无线资源控制层配置成使用Mode 2模式选择资源，且MAC层已确定当前传输是发送或一个多个协议数据单元PDU，且边链路数据在逻辑信道中可用时，先执行资源选择或重选过程的检查，在检查过程中，满足以下至少一个情况时，即可以看作满足上述预定条件：
-边链路资源重选计数器SL_RESOURCE_RESELECTION_COUNTER到0且随机生成的数小于上层配置的门限sl-ProbResourceKeep；
-资源池被配置或重配置；
-没有配置边链路授权；
-过去1s内没有在配置的边链路授权指示的资源上有任何传输或重传；
-资源上没有使用的连续传输机会的数量达到这个配置sl-ReselectAfter的个数；
-即使配置了最大的MCS，获取的资源还是无法承载对应的PDU；
-当前授权无法满足任意一个逻辑信道的包时延预算要求(Packet Delay Budget，PDB)，此时是继续发送还是进行资源重选取决于终端设备的实现；
-资源重评估发生了资源重叠；
-资源抢占检测发生了重叠且检测到的优先级大于待发数据优先级，且检测的RSRP大于门限。
在一些实施例中，在高层确定触发资源选择或资源重选时，从该高层向物理层提 供指示信息用于此次PSCCH/PSSCH传输(例如用于待发送的传输块TB传输)，该指示信息用于指示与HARQ传输相关的信息，其中，该HARQ传输相关的信息包括：HARQ重传/发送次数相关的信息，和/或待发边链路数据反馈使能指示信息，即该指示信息用于指示待发送的传输块TB的重传/发送次数，和/或待发送的传输块TB是否是HARQ-ACK反馈使能，换句话说，高层以TB为指示粒度，针对各个TB，分别向物理层提供指示信息。
在一些实施例中，该HARQ重传次数相关的信息包括：重传次数，和/或重传次数的范围，该HARQ发送次数相关的信息包括发送次数，和/或发送次数的范围；例如可以将第1次发送称为初始发送，将第2次及以上的发送称为重传；即发送次数等于重选次数加1，换句话说，该次数相关的信息可以是一个数值，也可以是一个数值范围，本实施例并不以此作为限制。
在一些实施例中，该待发边链路数据反馈使能指示信息是待发边链路数据是否是HARQ-ACK反馈使能相关的信息，是HARQ-ACK反馈使能(enable)或HARQ-ACK反馈禁用(disable)，例如，MAC PDU中的一个或多个逻辑信道对应的“sl-HARQ-FeedbackEnabled”参数可以被设置为“enabled”还是“disabled”，MAC层可以将上述参数的设置结果提供给物理层。
在一些实施例中，MAC层可以通过显式指示的方式将上述HARQ传输相关的信息指示给物理层，例如该指示信息可以是除前述MAC层提供给物理层的参数：资源池配置，待发数据包的L1优先级，待发数据包的时延预算，资源选择的粒度大小，周期业务对应的周期长度外新增的参数，例如HARQ重传/发送次数相关的信息的参数字段，和/或待发边链路数据反馈使能指示信息的参数字段。
在一些实施例中，MAC层可以通过隐式指示的方式将上述HARQ传输相关的信息指示给物理层，即与前述显式指示不同的是，不新增参数，而是将上述与HARQ传输相关的信息与现有的参数关联，使用现有的参数间接指示与HARQ传输相关的信息，例如该指示信息是表示优先级的参数字段L1priority和/或表示剩余时延预算的参数字段the remaining packet delay budget。其中，该优先级与该HARQ重传/发送次数相关的信息有第一映射关系，和/或该优先级与该待发边链路数据反馈使能指示信息有第二映射关系，和/或该剩余时延预算与该HARQ重传/发送次数相关的信息有第三映射关系，和/或该剩余时延预算与该待发边链路数据反馈使能指示信息有第四映 射关系。物理层根据接收到的优先级参数和/或剩余时延预算参数，以及上述各个映射关系，即可以确定HARQ传输相关的信息。针对上述映射关系，例如，第一映射关系即针对各个L1优先级(或优先级范围)，分别对应(映射)相同或不同的重传/发送次数相关的信息，即针对各个L1优先级(或优先级范围)，分别对应相同或不同的重传/发送次数值，或者对应相同或不同的重传/发送次数的范围；第二映射关系即针对各个L1优先级(或优先级范围)，分别对应(映射)HARQ-ACK反馈使能(enable)或HARQ-ACK反馈禁用(disable)；例如第三映射关系即针对各个剩余时延预算(或预算范围)，分别对应(映射)相同或不同的重传/发送次数相关的信息，即针对各个剩余时延预算(或预算范围)，分别对应相同或不同的重传/发送次数值，或者对应相同或不同的重传/发送次数的范围；第四映射关系即针对各个剩余时延预算(或预算范围)，分别对应(映射)HARQ-ACK反馈使能(enable)或HARQ-ACK反馈禁用(disable)；以上仅为示例说明，本实施例并不以此作为限制，例如还可以使用其他现有的参数字段隐式指示上述HARQ传输相关的信息，此处不再一一举例。
在一些实施例中，上述各个参数字段使用信息元(information element)表示，各个信息元的值是N个比特，N的数量可以根据需要确定，例如HARQ重传/发送次数相关的信息的参数字段使用信息元Harqtx/rxnum表示，其值可以是5个比特，在该5个比特分别为00010时，表示重传/发送次数为3次等；例如待发边链路数据反馈使能指示信息参数字段使用信息元Harqackfeedback表示，其值可以是1个比特，在该比特值是1时，表示反馈使能，在该比特值是0时，表示反馈禁用，反之亦然；此处不再一一举例，需要说明的是，以上信息元的名称仅为示例说明，本实施例并不以此作为限制。
在一些实施例中，该终端设备可以至少根据该指示信息指示的HARQ传输相关的信息来选择用于发送边链路数据的资源，例如该终端设备的物理层在接收到高层提供的指示信息后，至少根据该指示信息(还可以结合前述其他高层提供的参数)选择候选时域资源，该候选时域资源包括第一数量Y个时间资源单位，并从该Y个时间资源单位中选择候选资源集合set B(具体选择方法如前步骤1所述，此处不再赘述)，物理层将该set B上报给MAC层，由MAC层在set B中选择用于发送边链路数据的资源(例如，MAC层根据发送次数从候选资源集合中逐次选择至少一个资源，具体选择方法如前步骤2所述，此处不再赘述)，其中，每个时间资源单位可以是子帧， 时隙(包括14个符号symbol)，也可以是由少于14个符号symbol组成的部分时隙，也可以是由多于14个符号symbol组成的时间资源单位，本实施例并不以此作为限制。
在一些实施例中，在资源池配置了PSFCH的情况下，在该指示信息指示了该待发边链路数据是HARQ-ACK反馈使能时，该物理层选择该候选时间资源单位的第一数量Y除了要满足现有的要求，即大于或等于最小值参数信息minNumCandidateSlot配置的最小值外，从选择窗中选择的候选时域资源(即选择该Y个时间资源单位)还要满足：不会出现每个时间资源单位内均存在至少一个候选资源集合中的资源(即经过步骤1后所选的Y个时间资源单位中每个时间资源单位内均有包含在候选资源集合set B中的资源)时，从该Y个时间资源单位中选择的用于发送边链路数据的资源无法满足RTT GAP的情况，由此，可以保证待发数据的可靠性需求。
例如在资源池配置了PSFCH的情况下，在该指示信息指示了该待发边链路数据是HARQ-ACK反馈使能时，该物理层选择该候选时间资源单位的第一数量Y大于或等于最小值参数信息minNumCandidateSlot配置的最小值外，且从选择窗中选择的候选时域资源(即选择该Y个时间资源单位)还要满足：选择的候选时间资源单位的第一数量Y大于或等于HARQ重传/发送次数，和/或；在物理层获得候选资源集合后(即经过步骤1后)，每个时间资源单位内均存在该候选资源集合中的至少一个资源的情况下，从选择窗中选择的候选时域资源(即选择该Y个时间资源单位)还要满足：从该候选时域资源(Y个时间资源单位)中选择的资源(步骤2选择的资源)中相邻所选资源的间距大于或等于HARQ往返时延间隙(RTT GAP)。以上，限定了选择的Y个时间资源单位需要满足的条件，至于具体选择哪些时间资源单位中的哪些资源可以根据终端设备实现，本实施例并不以此作为限制。
在一些实施例中，对每个选择的PSSCH资源位置，HARQ RTT GAP具体计算方法如下：其长度z＝a+b，其中a等于相邻两个资源中的第一个资源的PSSCH的最后一个符号的结束时间到其对应的PSFCH接收的首个符号的开始时间；b为基于终端设备实现的一个时间段，用于PSFCH的接收和处理，以及对应PSSCH重传的准备时间(包括对应信道和生成时间和重传-传输/传输重传的转换时间)，PSFCH接收的首个符号的开始时间可以根据K和N计算确定。其中，K表示PSSCH和对应的PSFCH之间最小时间间隔(例如间隔可以用时隙个数表示)MinTimeGapPSFCH，N表示PSFCH资源周期(例如每隔多少时隙在时隙中有PSFCH)periodPSFCHresource，该 K和N是在资源池配置中配置的。
图6是选择Y个时间资源单位(以时隙为例)的示意图，如图6所示，与附图4所示不同的是，选择的Y个时隙能够在满足HARQ RTT GAP的情况下可以达到目标发送次数，由此，保证了待发数据的可靠性需求。
在一些实施例中，在操作502中选择了资源后，可以在该选择的资源上发送边链路数据，针对待发的边链路数据的一个传输块(TB，Transmission Block)可以包括一次或至少两次发送，因此502中可以选择一个或至少两个资源。其中，将上述一次或至少两次发送中时间上最靠前的发送称为第一次发送(简称为初传)，此外还可以包括一次或至少两次重传，分别使用选择的一个或至少两个资源执行上述一次或至少两次发送(初传和重传)。
图7是本实施例数据发送方法一示意图，如图7所示，该方法包括：
701，在满足预定条件时，高层确定触发资源选择或资源重选；
702，在高层确定触发资源选择或资源重选时，从该高层向物理层提供指示信息，用于指示与HARQ传输相关的信息；
703，物理层至少根据该指示信息选择候选资源集合；
704，物理层将该候选资源集合上报给高层；
705，高层从该候选资源集合中选择用于发送边链路数据的资源；
706，该终端设备在选择的资源上发送该边链路数据至其他终端设备。以上701-706的具体实施方式如前所述，此处不再重复。
值得注意的是，以上附图5，7仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图5，7的记载。
以上各个实施例仅对本申请实施例进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
由上述实施例可知，高层向物理层指示与HARQ传输有关的信息，由此使得选择出的资源满足待发数据目标发送次数的需求，保证待发数据的可靠性需求。
在现有标准中，针对一个资源池配置，其包括一个候选时隙数量Y的最小值参数minNumCandidateSF，但由于NR V2X可以支持的发送次数为1～32，则对于较小发送次数的传输块传输，希望Y的值尽可能小以保证省电；而对于较大发送次数的传输块传输，选择的Y的值不能过小，否则会导致无法达到目标发送次数。基于此，本申请实施例中提出了终端设备获取候选时间资源单位数量的最小值参数信息，该最小值参数信息包括至少一个与HARQ传输相关的信息对应的最小值，以便物理层根据上述信息选择发送边链路数据的资源，由此在支持HARQ重传机制的情况下，使得选择出的资源满足待发数据目标发送次数的需求，保证待发数据的可靠性需求。以下结合第二方面的实施例进行说明。
第二方面的实施例
本申请实施例提供一种数据发送方法，从终端设备进行说明。其中该终端设备(可称为发送终端设备)作为业务数据的发送方，向一个或多个其他终端设备(可称为接收终端设备)发送边链路数据。
图8是本申请实施例的数据发送方法的一示意图，如图8所示，该方法包括：
801，获取资源池配置信息，该资源池配置信息包括候选时间资源单位数量的最小值参数信息，该最小值参数信息包括至少一个与HARQ传输相关的信息对应的最小值；
802，至少根据该最小值参数信息选择候选时域资源，该候选时域资源包括第一数量个时间资源单位，并从该候选时域资源中选择资源用于边链路数据发送；
803，在选择的资源上发送该边链路数据。
由上述实施例可知，终端设备获取候选时间资源单位数量的最小值参数信息，该最小值参数信息包括至少一个与HARQ传输相关的信息对应的最小值；以便物理层根据上述信息选择发送边链路数据的资源，由此在支持HARQ重传机制的情况下，使得选择出的资源满足待发数据目标发送次数的需求，保证待发数据的可靠性需求。
值得注意的是，以上附图8仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图8的记载。
如前所述，在LTE中，在支持部分感知机制的情况下，物理层可以在部分子帧上进行感知，以达到省电目的，且在对应的选择窗中，基于终端设备实现，选择其中的部分子帧(以下称为Y个子帧)，从这Y个子帧中的候选资源中选择发送资源。Y的值需要大于或等于一个高层配置的最小值参数minNumCandidateSF。在一些实施例中，在801中，终端设备可以在资源池配置信息中获取最小值参数信息，该最小值参数信息表示候选时间资源单位数量Y的最小值，包括至少一个与HARQ传输相关的信息对应的最小值，该时间资源单位可以是子帧，时隙(包括14个符号symbol)，也可以是由少于14个符号symbol组成的部分时隙，也可以是由多于14个符号symbol组成的时间资源单位，本实施例并不以此作为限制，以下以该时间资源单位是时隙为例进行说明，即可以用minNumCandidateSlot表示该最小值参数信息，但本实施例并不以此作为限制，例如，还可以使用其他信息元表示该最小值参数信息；或者，该时间资源单位是除时隙外的其他单位时，该最小值参数可以表示为其他形式，此处不再一一举例。
在一些实施例中，该HARQ重传次数相关的信息包括：重传次数，和/或重传次数的范围，该HARQ发送次数相关的信息包括发送次数，和/或发送次数的范围。该待发边链路数据反馈使能指示信息是待发边链路数据是否是HARQ-ACK反馈使能相关的信息，即是HARQ-ACK反馈使能(enable)或HARQ-ACK反馈禁用(disable)。
在一些实施例中，可以预配置多个资源池，终端设备的高层从中自主选择一个资源池，进而可以获取该选择的资源池预配置的资源池配置信息，或者，可以由网络设备为终端设备配置专用的资源池，该终端设备通过接收网络设备发送的资源池配置信息的方式获取资源池配置信息，例如使用无线资源控制RRC信令获取该资源池配置信息，或者，网络设备可以使用系统信息块向终端设备发送资源池列表，终端设备从该列表中选择一个资源池，进而可以获取该选择的资源池预配置的资源池配置信息，以上仅为示例说明，本实施例并不以此作为限制。
在一些实施例中，资源配置信息中包含的该最小值参数信息包括至少一个与HARQ传输相关的信息对应(corresponding)的最小值，即该最小值参数信息和与HARQ传输相关的信息相关联(associated)，例如至少两个不同的HARQ重传或发送次数对应不同的最小值，和/或，至少两个不同的HARQ重传或发送次数的范围对应不同的最小值，该最小值可以从一个候选最小值集合中的一个最小值中选择，其中与 不同HARQ重传或发送次数对应的最小值集合不同，最小值集合不同包括最小值集合中的最小值都不相同，或者部分不相同。
例如，在HARQ重传/发送次数(或范围)为第1值(或第1范围)时，其对应的最小值为第1'值，在HARQ重传/发送次数(或范围)为第2值(或第2范围)时，其对应的最小值为第2'值，其中，第1'值与第2'值相同或不同。其中，至少两个不同的HARQ重传/发送次数对应不同的最小值，或者，至少两个不同的HARQ重传/发送次数的范围对应不同的最小值。例如针对一个资源池配置信息，该最小值参数信息包括一个最小值参数，该最小值参数中包括与各个HARQ重传/发送次数(或次数范围)对应的最小值，最小值参数信息具体表示为：
例1：最小值参数minNumCandidateSlot-r17:
{HARQ重传/发送次数(或范围)1,最小值1'},
{HARQ重传/发送次数(或范围)2,最小值2'}…
{HARQ重传/发送次数(或范围)N,最小值N'}.
或者，例如针对一个资源池配置信息，该最小值参数信息包括N个最小值参数，该N个最小值参数中，每个最小值参数中包括与与至少一个HARQ重传/发送次数(或次数范围)对应的最小值，具体表示为：
例2：最小值参数minNumCandidateslot-r17-1:
{HARQ重传/发送次数(或范围)1,最小值1'},
最小值参数minNumCandidateslot-r17-2:
{HARQ重传/发送次数(或范围)2,最小值2'}…
最小值参数minNumCandidateslot-r17-N:
{HARQ重传/发送次数(或范围)N,最小值N'}.
在一些实施例中，该最小值参数中可以针对HARQ重传/发送次数配置最小值，也可以针对HARQ重传/发送次数的范围配置最小值，也可以两者相结合，本实施例并不以此作为限制。
在一些实施例中，所述待发边链路数据反馈使能指示信息是HARQ-ACK反馈使能或HARQ-ACK反馈禁用，所述最小值参数信息包括与HARQ-ACK反馈使能对应的至少一个最小值参数，和/或与HARQ-ACK反馈禁用对应的至少一个最小值参数，即分别为HARQ-ACK反馈使能和HARQ-ACK反馈禁用独立配置该最小值参数信息。 其中，在HARQ-ACK反馈使能时，其对应的最小值为第1'值，在HARQ-ACK反馈禁用时，其对应的最小值为第2'值，其中，第1'值与第2'值相同或不同。例如针对一个资源池配置信息，该最小值参数信息包括一个最小值参数，该最小值参数中，包含与HARQ-ACK反馈使能对应的最小值和与HARQ-ACK反馈禁用对应的最小值，该最小值参数具体表示为：
最小值参数minNumCandidateSlot-r17:
{HARQ-ACK反馈使能,最小值1},
{HARQ-ACK反馈禁用,最小值2}…
或者，例如针对一个资源池配置信息，该最小值参数信息包括2个最小值参数，该2个最小值参数分别是与HARQ-ACK反馈使能对应的最小值和与HARQ-ACK反馈禁用对应的最小值，具体表示为：
最小值参数minNumCandidateSlot-HARQenabled-r17:
{最小值1},
最小值参数minNumCandidateSlot-HARQdisabled-r17:
{最小值2}…
在一些实施例中，该最小值参数信息minNumCandidateSlot可以同时和HARQ重传或发送次数相关的信息以及待发边链路数据反馈使能指示信息对应；其具体实现方式可以结合以上实施方式，例如，针对HARQ-ACK反馈使能和HARQ-ACK反馈禁用对应各自的最小值参数minNumCandidateSlot-HARQenabled-r17和minNumCandidateSlot-HARQdisabled-r17，其中minNumCandidateSlot-HARQenabled-r17中包含如上述例1的配置内容，minNumCandidateSF-HARQdisabled-r17中包含如上述例1的配置内容。例如：
例3：最小值参数minNumCandidateSlot-HARQenabled-r17:
{HARQ重传/发送次数(或范围)1,最小值1a},
{HARQ重传/发送次数(或范围)2,最小值2a}…
{HARQ重传/发送次数(或范围)N,最小值Na}.
最小值参数minNumCandidateSlot-HARQdisabled-r17:
{HARQ重传/发送次数(或范围)1,最小值1b'},
{HARQ重传/发送次数(或范围)2,最小值2b}…
{HARQ重传/发送次数(或范围)N,最小值Nb}.
或者该最小值参数信息还可以表示为：
例4：最小值参数minNumCandidateSlot-HARQenabled-r17-1:
{HARQ重传/发送次数(或范围)1,最小值1a},
最小值参数minNumCandidateSlot-HARQenabled-r17-2:
{HARQ重传/发送次数(或范围)2,最小值2a}…
最小值参数minNumCandidateSlot-HARQenabled-r17-N:
{HARQ重传/发送次数(或范围)N,最小值Na}.
最小值参数minNumCandidateSlot-HARQdisabled-r17-1:
{HARQ重传/发送次数(或范围)1,最小值1b'},
最小值参数minNumCandidateSlot-HARQdisabled-r17-2:
{HARQ重传/发送次数(或范围)2,最小值2b}…
最小值参数minNumCandidateSlot-HARQdisabled-r17-N:
{HARQ重传/发送次数(或范围)N,最小值Nb}.
在一些实施例中，上述各个参数字段(例如minNumCandidateSlot)使用信息元(information element)表示，各个信息元的值(范围)用N个比特表示，N的数量可以根据需要确定，此处不再一一赘述，需要说明的是，以上信息元的名称仅为示例说明，本实施例并不以此作为限制。
在一些实施例中，HARQ重传/发送次数范围表示重传/发送次数的候选值集合，最小值范围表示最小值的候选值集合，前文所述的不同的范围可以是各个范围内的候选值完全不同，或部分不同，本实施例并不以此作为限制。
在一些实施例中，该方法还可以包括(未图示)：终端设备从高层(例如MAC层)向物理层提供该最小值参数信息，例如该最小值参数信息可以还是包含在资源池配置信息中提供给物理层。因此，
在一些实施例中，该方法还可以包括(未图示)：物理层根据高层向物理层指示的与HARQ传输相关的信息(具体请参考第一方面的实施例)以及该最小值参数信息确定使用的最小值参数；例如，物理层可以在上述例1～4中的最小值参数信息中找到与该与HARQ传输相关的信息对应的最小值参数，根据最小值参数确定使用的最小值，例如针对例1，在HARQ发送次数是1时，找到其对应的最小值参数是最小值 1'，或者发送次数1在HARQ发送次数范围1内，找到其对应的最小值参数是1'。
在一些实施例中，在802中，物理层至少根据该最小值参数信息选择候选时域资源，该候选时域资源包括第一数量个时间资源单位，并从该候选时域资源中选择资源用于边链路数据发送；例如，物理层在根据该最小值参数信息确定使用的最小值后，可以在选择窗内选择第一数量Y个时间资源单位，作为候选时域资源，其中，该候选时间资源单位的第一数量Y大于或等于该使用的最小值。另外一个时间资源单位
Figure PCTCN2020090379-appb-000003
被包含在选择窗中所选择的Y个候选时间资源单位集合当中，那么对应的子帧
Figure PCTCN2020090379-appb-000004
需要是在感知窗中对应进行了感知的子帧。
在一些实施例中，在802中，物理层从该Y个时间资源单位中选择候选资源集合set B(具体选择方法如前步骤1所述，此处不再赘述)，物理层将该set B上报给MAC层，由MAC层在set B中选择用于发送边链路数据的资源(例如，MAC层根据发送次数从候选资源集合中逐次选择至少一个资源，具体选择方法如前步骤2所述，此处不再赘述)，其中，每个时间资源单位可以是子帧，时隙(包括14个符号symbol)，也可以是由少于14个符号symbol组成的部分时隙，也可以是由多于14个符号symbol组成的时间资源单位，本实施例并不以此作为限制。
在一些实施例中，在资源池配置了PSFCH的情况下，在与HARQ传输相关的信息中指示该待发边链路数据是HARQ-ACK反馈使能时，在操作802中，该物理层选择该候选时间资源单位的第一数量Y除了要满足现有的要求，即大于或等于最小值参数信息minNumCandidateSlot配置的最小值外，从选择窗中选择的候选时域资源(即选择该Y个时间资源单位)还要满足：不会出现每个时间资源单位内均存在至少一个候选资源集合中的资源(即经过步骤1后所选的Y个时间资源单位中每个时间资源单位内均有包含在候选资源集合set B中的资源)时，从该Y个时间资源单位中选择的用于发送边链路数据的资源无法满足RTT GAP的情况，由此，可以保证待发数据的可靠性需求。
例如在资源池配置了PSFCH的情况下，在与HARQ传输相关的信息中指示该待发边链路数据是HARQ-ACK反馈使能时，在操作802中，该物理层选择该候选时间资源单位的第一数量Y大于或等于最小值参数信息minNumCandidateSlot配置的最小值外，且从选择窗中选择的候选时域资源(即选择该Y个时间资源单位)还要满足： 选择的候选时间资源单位的第一数量Y大于或等于HARQ重传/发送次数，和/或；在物理层获得候选资源集合后(即经过步骤1后)，每个时间资源单位内均存在该候选资源集合中的至少一个资源的情况下，从选择窗中选择的候选时域资源(即选择该Y个时间资源单位)还要满足：从该候选时域资源(Y个时间资源单位)中选择的资源(步骤2选择的资源)中相邻所选资源的间距大于或等于HARQ往返时延间隙(RTT GAP)。以上，限定了选择的Y个时间资源单位需要满足的条件，至于具体选择哪些时间资源单位中的哪些资源可以根据终端设备实现，本实施例并不以此作为限制。其具体实施方式可以参考第一方面的实施例，此处不再赘述。
在一些实施例中，该操作803的实施方式可以参考第一方面实施例中操作503，此处不再赘述。
