Description

旁链路信息的传输方法、终端和控制节点
相关申请的交叉引用
本申请主张在2019年7月24日在中国提交的中国专利申请号No.201910673801.7的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种旁链路信息的传输方法、终端和控制节点。
背景技术
在新空口(New Radio，NR)系统中，对于下行数据包的传输，终端可以根据自己的接收和解码状况，在物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)或者物理上行共享信道((Physical Uplink Shared Channel，PUSCH)上反馈混合自动重传请求应答(Hybrid Automatic Repeat reQuest-Acknowledgement，HARQ-ACK)信息(即非确认字符NACK或者确认字符ACK)来告知控制节点该下行数据包的传输是否成功，从而帮助控制节点决定是否需要重传。
在旁链路(sidelink)上，终端通过物理旁链路控制信道(Physical Sidelink Control Channel,PSCCH)发送旁链路控制信息(Sidelink Control Information，SCI)，调度物理旁链路共享信道(Physical Sidelink Shared Channel,PSSCH)的传输以发送sidelink数据。为了提高sidelink上数据传输的可靠度和资源利用率，在NR sidelink技术中也引入了HARQ反馈机制：sidelink接收终端收到sidelink数据后可以反馈sidelink HARQ-ACK信息来指示sidelink的传输是成功还是失败，该HARQ应答通过物理旁链路反馈信道(Physical Sidelink Feedback Channel，PSFCH)发送。
但是和NR Uu口下行数据包的HARQ反馈机制不同的是，sidelink传输可能并不是在控制节点和终端之间进行的，而是在终端和终端之间的sidelink上进行的，因此控制节点无法直接知道该sidelink数据包的传输是否成功，需 要由终端将Sidelink HARQ-ACK信息发送给控制节点，从而控制节点才可以进一步确定sidelink上的传输是否成功，并最终确定接下来是否需要调度发送终端在sidelink上进行重传。
sidelink终端如何将sidelink信息发出去的具体步骤和细节都还没有讨论。

下面结合附图介绍本公开的实施例。本公开的一些实施例提供的一种旁链路信息的传输方法、终端和控制节点可以应用于无线通信系统中。该无线通信系统可以为采用5G系统，或者演进型长期演进(Evolved Long Term Evolution，eLTE)系统，或者后续演进通信系统。
请参见图1a和图1b，图1a和图1b是本公开的一些实施例可应用的网络系统的结构图，如图1所示，包括第一终端11、第二终端12和控制节点13，其中，第一终端11和第二终端12可以是用户终端或者其他终端侧设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本公开的一些实施例中并不限定第一终端11和第二终端12的具体类型。上述控制节点13可以为网络设备，也可以中终端。该网络设备可以是5G基站，或者以后版本的基站，或者其他通信系统中的基站，或者称之为节点B，演进节点B，或者发送接收点(Transmission Reception Point，TRP)，或者接入点(Access Point，AP)，或者所述领域中其他词汇，只要达到相同的技术效果，所述网络设备不限于特定技术词汇。另外，上述网络设备可以是主节点(Master Node，MN)，或者辅节点(Secondary Node，SN)。需要说明的是，在本公开的一些实施例中仅以5G基站为例，但是并不限定网络设备的具体类型。
请参见图2，图2是本公开的一些实施例提供的一种旁链路信息的传输方法的流程图，该方法应用于终端，如图2所示，包括以下步骤：
步骤201，将旁链路信息映射为目标通知信息；
步骤202，在目标资源上发送所述目标通知信息。
在本公开的一些实施例中，上述终端为旁链路传输系统中除控制节点以外的终端，例如，可以为发送旁路传输的发送终端，也可以为接收旁链路传输的接收终端，还可以为中间终端，该中间终端为所述发送终端或者所述接 收终端传输数据到控制节点的中间传输节点，该中间传输节点不包括发送终端。以下各实施例中，以终端为旁路传输的发送终端和旁路传输的接收终端为例进行说明。此时，上述目标通知消息的接收方可以为控制节点，也可以为上述中间终端，以下各实施例中，以目标通知信息的接收方为控制节点为例进行说明。
可选的，上述终端为发送终端时，发送终端可以通过PSFCH或PSSCH接收旁链路信息。上述终端为接收终端时，可以根据旁链路传输的接收状态确定旁链路信息。为例方便理解，以下对发送终端接收旁链路信息以及接收终端确定旁链路信息统称为终端获取旁链路信息。
本实施例中，在终端获取旁链路信息后，可以将该旁链路信息映射为目标通知信息，并利用目标资源将该目标通知信息发送至控制节点。该旁链路信息包含对应一个或者多个sidelink传输的sidelink HARQ-ACK信息，旁链路调度请求(Scheduling request，SR)和信道状态信息(Channel State Information，CSI)等中的至少一项。上述控制节点可以支持sidelink链路和/或Uu链路，其中，终端将sidelink信息映射为目标通知信息，若通过sidelink链路发送至控制节点时，该控制节点可以称之为sidelink控制节点；若通过Uu链路发送至控制节点时，该控制节点可以称之为Uu控制节点。当控制节点为Uu控制节点时，上述目标资源可以为PUCCH或PUSCH。当控制节点为sidelink控制节点，目标资源可以为PSFCH或PSSCH。
本公开的一些实施例通过将旁链路信息映射为目标通知信息，这样可以帮助控制节点理解旁链路信息，实现了旁链路信息的传输。
应理解，将上述旁链路信息映射为目标通知信息的方式可以根据实际需要进行设置，以下对此进行详细说明。
在一可选实施例中，所述旁链路信息映射为所述目标通知信息的方式以下至少一项：
映射方式1：将N1个第一比特中的每一比特映射为1个第二比特；
映射方式2：将N2个第一比特映射为M1个第二比特；
映射方式3：按照预设方式，将N3个比特映射为W个第二比特；
映射方式4：将N4个第一比特形成的比特序列关联的第一比特序列，确 定为所述N4个第一比特对应的第二比特的指示信息；
其中，所述第一比特为所述旁链路信息中的比特，所述第二比特为所述目标通知信息中的比特；N1、N2和W均为正整数，N3和N4为大于1的整数，M1为大于N2的整数，N3大于W。
需要说明的是，所述将旁链路信息映射为目标通知信息包括至少两项映射方式时，不同的映射方式可以对应旁链路信息的不同部分,例如旁链路信息的前N bit和后M bit对应不同的映射方式；也可以是不同的信息类型对应不同的映射方式，例如CSI和HARQ-ACK对应不同的映射方式，具体在此不做进一步限定。
对应上述映射方式1，可以理解为：旁链路信息与目标通知信息中的比特为一一映射关系。第一比特所指示的状态和对应的第二比特所指示的状态相同。例如，当第一比特为HARQ-ACK信息的比特时，第一比特所指示的状态和对应的第二比特所指示的状态相同。例如对于HARQ-ACK比特，旁链路信息中的第一比特指示为ACK，对应的目标通知信息中的第二比特指示为ACK。旁链路信息中的第一比特指示为NACK，对应的目标通知信息中的第二比特指示为NACK。
对应上述映射方式2，可以理解为：对旁链路信息进行拓展，得到目标通知信息，例如可以通过进行重复和/或增加冗余bit实现拓展，从而可以提高可靠性。本实施例中，上述将N2个第一比特映射为M1个第二比特包括以下任一项：
方案1：将所述N2个第一比特映射为M2个第二比特后，在所述M2个第二比特中插入M3个比特的第二比特序列，得到所述M1个第二比特；
方案2：在所述N2个第一比特插入M4个比特的第三比特序列后，将N2个第一比特和所述第三比特序列的组合比特映射为所述M1个第二比特；
方案3：将所述N2个第一比特中每个比特重复至少1次后，进行级联得到所述M1个第二比特；
方案4：将所述N2个第一比特中每个比特重复至少1次后，进行级联并插入至少一个第四比特序列，得到所述M1个第二比特；
方案5：将至少两个目标对象进行级联，得到所述M1个第二比特；
方案6：将至少两个目标对象进行级联后，插入至少一个第四比特序列，得到所述M1个第二比特；
其中，所述目标对象为所述N2个第一比特，M2、M3和M4均为正整数。
本实施例中，上述第二比特序列可以为以下任一项：
M3个固定状态；
M3个冗余比特；
M3个校验位。
当第二比特序列为冗余比特时，可以提高旁链路信息传输的可靠性。
在方案1中，上述第二比特序列可以由网络侧配置、网络侧预配置、协议约定、终端间协商或其他终端指示等，在此不做进一步的限定。可选的，在所述M2个第二比特中插入一个或者多个第二比特序列，当第二比特序列的数量为1时，该第二比特序列可以位于M2个第二比特之前或者之后，还可以位于M2个第二比特中任意两个第二比特之间。例如，第二比特序列为11，M2个第二比特为0000，一个第二比特序列插入到M2个第二比特形成的M1个第二比特可能为110000、000011或001100等。进一步的，两个第二比特序列插入到M2个第二比特形成的M1个第二比特可能为11000011、00001111、01100110或00110011等。当然在其他实施例中，上述第二比特序列可以为1个或者多个比特，在此不做进一步的限定。
在方案2和方案6中，上述第三比特序列和第四比特序列可以与第二比特序列的形式一致，具体可以参照第二比特序列的描述在此不做再赘述。
在方案3至方案6中通过对第一比特重复，得到至少两个重复的第二比特。上述方案3和方案4是针对每一第一比特单独重复，例如，在方案3中，N2个第一比特为1100，且M1的值为8时，M1个第二比特为11110000。在方案4中，N2个第一比特为1100，且M1的值为10，第四比特序列为“X”时，M1个第二比特可能为11110000XX、X11110000X、X1111X0000或X1X1110000等。上述方案5和方案6是针对N2第一比特为整体进行复制，例如，在方案6中，上述N2个第一比特为1100，且M1为10时，M1个第二比特为11001100XX，其中M1个第二比特包含两个第四比特序列“X”，该 “X”可以为固定值。当然在其他实施例中第四比特序列还可以设置在其他位置，例如M1个第二比特为还可能为X11001100X、1100 X 1100X或X1X1001100等。
应理解，针对上述方案4和方案6，可以进一步的对重复之后的比特进行映射前或者映射后插入，当然也可以不做进一步的映射。
进一步的，在上述方案1中，将N2个第一比特映射为M2个第二比特包括：
将所述N2个第一比特中的每一个比特映射为1个第二比特；
按照预设方式，将所述N2个第一比特中的N3个比特映射为W个第二比特，N3和W为正整数，且N3大于W。
本实施例中，上述N2个第一比特可以包括一个或者多个映射单元，每一映射单元的比特数量可以相同也可以不同，上述N3的取值为映射单元的比特数量的最小值。
对应上述映射方式3，可以理解为，首先在N2个第一比特插入第三比特序列，然后进行映射。在一可选实施例中，上述将N2个第一比特和所述第三比特序列的组合比特映射为所述M1个第二比特包括：
将所述组合比特中的每一比特映射为1个第二比特；
按照预设方式，将所述组合比特中的N3个比特映射为W个第二比特，N3和W为正整数，且N3大于W。
本实施例中，上述N2个第一比特可以包括一个或者多个映射单元，每一映射单元的比特数量可以相同也可以不同，上述N3的取值为映射单元的比特数量的最小值。
进一步的，上述预设方式可以理解为一种压缩方式，具体的压缩计算方式可以根据实际需要进行设置，以下以四个第一比特映射为1个第二比特为例进行说明。例如在本公开的一些实施例中，上述预设方式包括以下至少一种压缩方式：
至少两个比特中包括至少一个比特指示第一值的情况下，所述至少两个比特对应的1个第二比特指示第一值，所述至少两个比特为所述N3个比特中的比特；该第一值的具体表现形式可以根据对应比特的信息类型确定，例 如对于sidelink HARQ-ACK信息，该第一值为非确认字符(例如可以使用0表示非确认字符，使用1表示确认字符；或者，使用1表示非确认字符，使用0表示确认字符)。
所述至少两个比特均指示第二值的情况下，所述至少两个比特对应的1个第二比特指示第二值；该第二值的具体表现形式可以根据对应比特的信息类型确定，例如对于sidelink HARQ-ACK信息，该第二值为确认字符。例如可以使用1指示确认字符,此时，若终端获取到的4个第一比特均指示确认字符，则该4个第一比特映射的第二比特指示确认字符。
所述至少两个比特中包括至少一个比特指示第二值的情况下，所述至少两个比特对应的1个第二比特指示第二值；例如对于sidelink HARQ-ACK信息，该第二值为确认字符。例如可以使用1指示确认字符，此时，若终端获取到的4个第一比特为0001，则该4个第一比特映射的第二比特指示确认字符。
所述至少两个比特均指示第一值的情况下，所述至少两个比特对应的1个第二比特指示第一值；例如对于sidelink HARQ-ACK信息，该第一值为非确认字符。例如可以使用0指示非确认字符，此时，若终端获取到的4个第一比特为0000，则该4个第一比特映射的第二比特指示非确认字符。
将所述至少两个比特进行与操作，得到所述至少两个比特对应的第二比特的指示信息；
将所述N3个比特求和后模P，得到所述W个第二比特的指示信息，P为大于1的整数；
将所述至少两个比特求或，得到所述至少两个比特对应的1个第二比特的指示信息；
将所述至少两个比特求异或，得到所述至少两个比特对应的1个第二比特的指示信息；
根据所述至少两个比特对应的值所属的区间范围，确定所述至少两个第一比特对应的1个第二比特的指示信息。该区间范围可以包括至少两个区间范围，且各区间范围不存在交集。上述至少两个比特对应的值可以为至少两个比特对应的和值，或者还可以为至少两个比特作为二进制编码所对应的十 进制值。例如上述区间范围包括第一范围(小于5)和第二范围(大于或等于5)，此时，若至少两个比特对应的值为4，则确定该至少两个比特对应的1个第二比特可以为第一值，该第一值为0；若至少两个比特对应的值为6，则确定该至少两个比特对应的1个第二比特可以为第二值，该第二值可以为1。当然在其他实施例中，该第一范围对应指示的值可以为第二值，第二范围对应指示的值可以为第一值，在此不做进一步的限定。
应理解，上述进行与操作可以包括求与和求位与两种方式，以求与为例，若对1100求与计算后，得到的1个第二比特，且该第二比特为0。
需要说明的是，上述N3个比特可以包括一个或者多个映射单元，每一映射单元的比特数量可以相同也可以不同，上述N3的取值为映射单元的比特数量的最小值。当包括多个映射单元时，需要对每一个映射单元映射的结果进行级联。例如，假设存在10bit的sidelink信息，若映射单元为10bit，此时将10bit的sidelink信息上述预设方式映射为1个第二比特，则无需进行级联；若映射单元为5bit，此时将每5bit的sidelink信息按照上述预设方式映射为1个第二比特，则最终将会级联得到2个第二比特。
进一步的以上述P的取值可以根据实际需要进行设置，在此不做进一步的限定。当P的取值为2时，对应的W为1；当P的取值为3或者4时，对应的W为2。
需要说明的是，对于同一sidelink信息，可以采用上述预设方式中的一种或者多种方式进行映射，当采用多种方式进行映射时，可以对不同部分或者不同类型的信息采用不同的方式进行映射，在此不做进一步的限定。
进一步的，本实施例中，上述方法还包括：
接收控制节点发送的调度信令，所述调度信令用于指示旁链路资源；
在所述旁链路资源进行上进行旁链路传输。
应理解，上述控制节点可以在上述调度信令中对指示的旁链路资源用于初传和重传进行区分。
可选的，上述调度信令还可以用于指示所述旁链路资源用于重传或者初传。
本实施例中，无论调度信令是否对重传进行区分，终端都可以根据 sidelink信息或者目标通知信息进行重传操作。此外，还可以对调度信令指示重传的sidelink传输进行重传。
其中，旁链路资源可以包括针对一个或者多个sidelink传输的资源，例如，当旁链路资源包含针对4个sidelink传输的资源时，可以通过一个DCI指示4个资源，也可以通过4个DCI指示4个资源，其中每一个DCI指示一个资源。本实施例中，当旁链路资源为4个资源时，可以根据网络设备指示进行重传的sidelink传输重传；也可以依据sidelink信息中sidelink HARQ-ACK信息进行重传；还可以依据目标通知信息中特定比特的指示状态进行重传，该特定比特是指sidelink HARQ-ACK信息映射为目标通知信息中的比特。
例如，在一可选实施例中，若依据目标通知信息中特定比特的指示状态进行重传的情况下，可以对指示状态为NACK的特定比特对应的sidelink传输进行重传。假如某一特定比特对应4个sidelink传输的sidelink HARQ-ACK信息，即该特定比特对应4 bit sidelink HARQ-ACK(如0011)，且该一特定比特为这4 bit sidelink HARQ-ACK求与的结果，从而得到该特定比特为0。此时，终端可以对该4 bit sidelink HARQ-ACK中指示为非确认字符对应的2个sidelink传输进行重传，也可以对该4 bit sidelink HARQ-ACK对应的4个sidelink传输进行重传。
在另一可选实施例中，依据sidelink信息中sidelink HARQ-ACK信息进行重传时，可以只对实际传输失败的sidelink传输进行重传，假如实际存在三个传输失败的sidelink传输，每个sidelink传输对应1个资源，此时可以在这三个传输失败的sidelink传输对应的资源上进行重传，在另一个资源上不传输，或者进行其他TB的初传。
调度信令在资源分配同时指示了该资源分配是否用于重传，此时在另一可选实施例中，终端可以根据调度信令的指示来进行重传。例如调度信令指示TB1重传，则无论目标通知信息和sidelink信息中对应TB1的比特指示的状态为NACK还是ACK，终端都重传TB1。
本实施例中，上述在所述旁链路资源进行上进行旁链路传输包括以下一项：
对第一旁路信息对应的旁链路数据进行旁链路重传，所述第一旁路信息为第一比特指示非确认字符的旁路信息；
对第二旁路信息对应的旁链路数据进行旁链路重传，所述第二旁路信息为第二比特指示非确认字符对应的旁路信息；
在控制节点指示旁链路数据进行重传的情况下，对指示进行重传的旁链路数据进行旁链路重传。
可选的，所述目标资源的数量为多个的情况下，所述在目标资源上发送所述目标通知信息包括：在多个所述目标资源上发送所述目标通知信息。本实施例中，在多个所述目标资源上发送所述目标通知信息可以理解为，重复发送目标通知信息，这样可以提高目标通知信息传输的可靠性，避免终端处于小区边缘时，或者突然遭信道恶化时，只向控制节点发送一次目标通知信息可能无法保证该目标通知信息一本会被控制节点检测和正确解码，导致sidelink的进程会被挂起，从而导致无法满足业务的时延要求。
为了更好的理解本公开，以下通过sidelink终端(以下简称终端)将sidelink信息(以sidelink HARQ-ACK信息为例进行说明)发送给控制节点为例，对本公开的实现过程进行详细说明。
其中，终端可以包括发送终端(发送sidelink传输的终端)和接收终端(接收sidelink传输的终端)。上述控制节点可以支持sidelink链路和/或Uu链路，其中，终端将sidelink信息映射为目标通知信息，若通过sidelink链路发送至控制节点时，该控制节点可以称之为sidelink控制节点，目标通知信息可以理解为sidelink HARQ-ACK信息；若通过Uu链路发送至控制节点时，该控制节点可以称之为Uu控制节点，目标通知信息可以理解为Uu HARQ-ACK信息。当然，sidelink HARQ-ACK信息和Uu HARQ-ACK信息仅用于对终端通过不同的链路传输的HARQ-ACK信息进行区分，并不用于限定传输的内容。也有可能sidelink HARQ-ACK信息与Uu HARQ-ACK信息统称为HARQ-ACK信息。
应理解，终端获取sidelink信息的情况包括：
情况1：发送终端发送sidelink传输，接收终端接收sidelink传输并确定对应的sidelink HARQ-ACK信息，接收终端通过PSFCH或者PSSCH将 sidelink HARQ-ACK信息反馈给发送终端，发送终端接收对应至少一个sidelink传输的sidelink HARQ-ACK信息或者接收来自至少一个接收终端的sidelink HARQ-ACK信息，这些信息为sidelink信息。此时由发送终端向控制节点报告。
情况2：接收终端接收至少一个sidelink传输并确定对应的sidelink HARQ-ACK信息，这些信息为sidelink信息，此时由RX UE向控制节点报告。
发送终端或者接收终端将sidelink信息映射为目标通知信息；当控制节点为Uu控制节点时，将映射后的信息通过目标资源(上行资源)报告给基站；当控制节点为sidelink控制节点时，将映射后的信息通过目标资源(sidelink资源)报告给sidelink控制节点。
在一实施方式中，以控制节点为Uu控制节点为例进行说明，具体终端将sidelink信息映射为目标通知信息并发送的步骤包括：
步骤1，获取sidelink HARQ-ACK信息后，终端按照如下方式中的至少一种方法将终端获取K比特的sidelink HARQ-ACK信息映射为Uu HARQ-ACK信息。
方法1(一一对应)：每个sidelink HARQ-ACK bit对应一个Uu HARQ-ACK bit；
注意这里不代表终端只收到1个sidelink HARQ-ACK bit或者终端只发送1个Uu HARQ-ACK bit，而且这不同的sidelink HARQ-ACK bit可能来自不同的反馈资源(例如PSFCH或PSSCH)或者对应不同的sidelink传输。
如果在收到的sidelink HARQ-ACK信息中一个sidelink HARQ-ACK bit指示ACK则认为对应一个Uu HARQ-ACK bit且该bit指示ACK；如果在sidelink收到的sidelink HARQ-ACK信息中一个sidelink HARQ-ACK bit指示NACK则认为对应一个Uu HARQ-ACK bit且该bit指示NACK。
本方法实施例中，终端收到N bit sidelink HARQ-ACK信息后，确定对应的N bit Uu HARQ-ACK信息，并在对应PUCCH资源上发给控制节点。
可选的一个例子是，一个PSFCH资源对应一个PUCCH资源，即终端在一个PSFCH资源上收到N bit sidelink HARQ-ACK信息后，确定对应的N  bit Uu HARQ-ACK信息，并在对应的PUCCH资源上发给控制节点。除了PSFCH之外，携带sidelink HARQ-ACK信息的还可能是PSSCH，除了PUCCH之外，携带UCI的还可以是PUSCH。可以任意组合，不做赘述。
方法2(压缩或者拓展)每K1个sidelink HARQ-ACK bit对应T1个Uu HARQ-ACK bit。
注意这里不代表终端只收到K1个sidelink HARQ-ACK bit或者终端只发送T1个Uu HARQ-ACK bit，而且这K1个bit可能来自不同的反馈资源(例如PSFCH或PSSCH)或者对应不同的sidelink传输。
方法2包括方法2.1和方法2.2；
方法2.1:对于K1>T1，K1个sidelink HARQ-ACK bit经过预设方式计算得到T1 bit结果，若该结果中一个bit指示ACK，则认为该bit对应一个Uu HARQ-ACK bit，且该bit指示ACK；若该结果指示NACK，则认为该bit对应一个Uu HARQ-ACK bit，且该bit指示NACK；基于该原则确定T1 bit的Uu HARQ-ACK信息。
例如，终端收到K1 bit sidelink HARQ-ACK信息后，确定对应的T1 bit Uu HARQ-ACK，并在对应PUCCH资源上发给控制节点，其中T1并不等于K1。此时每K1/T1个sidelink传输对应一个Uu HARQ-ACK bit。
控制节点收到该T1 bit Uu HARQ-ACK信息后，行为包含以下至少一项：对于指示为NACK的bit对应的K1/T1个sidelink传输，认为传输失败，控制节点可以通过发送调度信令调度该终端进行重传。
在一实施例中，T1＝1时，即终端收到K1 bit sidelink HARQ-ACK信息后，确定对应的1 bit Uu HARQ-ACK在对应PUCCH资源上发给控制节点，此时因为这每K1个sidelink传输对应一个Uu HARQ-ACK bit。控制节点收到该1 bit Uu HARQ-ACK信息后，行为包含以下至少一项：若该bit指示NACK，认为这K1个sidelink传输失败。进一步可选地，控制节点可以通过发送调度信令调度该终端重传这K1个sidelink传输。除了PSFCH之外，携带sidelink信息的还可能是PSSCH，除了PUCCH之外，携带UCI的还可以是PUSCH。可以任意组合，不做赘述。
当T1大于1时，上述预设方式可以包括以下至少一项：
当连续K1/T1个sidelink HARQ-ACK bit不全为ACK时，对应的1bit Uu HARQ-ACK bit指示NACK，当连续K1/T1个sidelink HARQ-ACK bit全为ACK时，对应的1bitUu HARQ-ACK bit指示ACK；
当连续K1/T1个sidelink HARQ-ACK bit不全为NACK时，对应的1bit Uu HARQ-ACK bit指示ACK，当连续K1/T1个sidelink HARQ-ACK bit全为NACK时，对应的1bit Uu HARQ-ACK bit指示NACK。
进行与操作，应理解，上述进行与操作可以包括求与和求位与两种方式，以求与为例，例如每连续K1/T1个sidelink HARQ-ACK bit求与，算出的结果对应一个Uu HARQ-ACK bit，将算出的所有bit进行级联，从而最终获得对应M bit的Uu HARQ-ACK；
求和后模2，例如每连续K1/T1个sidelink HARQ-ACK bit求位和后模2，算出的结果对应一个Uu HARQ-ACK bit，从而最终对应M bit的Uu HARQ-ACK；
求或，例如每连续K1/T1个sidelink HARQ-ACK bit求或，算出的结果对应一个Uu HARQ-ACK bit，从而最终对应M bit的Uu HARQ-ACK；
求异或，例如每连续K1/T1个sidelink HARQ-ACK bit求异或，算出的结果对应一个Uu HARQ-ACK bit，从而最终对应M bit的Uu HARQ-ACK；
取值对应的范围，例如K1/T1 bit取值为某一范围时，对应一个Uu HARQ-ACK bit指示ACK；例如K1/T1 bit取值为另一范围时，对应一个Uu HARQ-ACK bit指示NACK。
方法2.2：对于K1<T1，包括方法2.2.1和方法2.2.2。
方法2.2.1，对K1个sidelink HARQ-ACK bit填补O bit固定状态得到T1 bit结果，若该结果中一个bit指示ACK，则认为该bit对应一个Uu HARQ-ACK bit，且该bit指示ACK；若该结果指示NACK，则认为该bit对应一个Uu HARQ-ACK bit，且该bit指示NACK；基于该原则确定T1 bit的Uu HARQ-ACK信息；
在一可选实施例中，可以将K1个sidelink HARQ-ACK bit先按照方法1中的描述映射为K1 bit Uu HARQ-ACK信息,再填补O bit。
在一可选实施例中，可以将K1个sidelink HARQ-ACK bit先按照方法 2.1中的描述映射为1个或者多个bit Uu HARQ-ACK信息，再填补O bit。
在一可选实施例中，可以将先在K1个sidelink HARQ-ACK bit中填补O bit，然后再按照方法2.1中的描述映射为T1 bit的Uu HARQ-ACK信息。
可选的，填补的O bit为O bit的0或者Obit的NACK或者Obit的其他固定状态或者O bit冗余bit或者O bit校验位。
例如T1＝Q*K1，终端收到N bit sidelink HARQ-ACK信息后，确定对应的M bit Uu HARQ-ACK，并在对应PUCCH资源上发给控制节点，其中T1并不等于K1。此时每个sidelink传输对应T1/K1个Uu HARQ-ACK bit。
控制节点收到该T1 bit Uu HARQ-ACK信息后，行为包含以下至少一项：
若某个sidelink传输对应的T1/K1个Uu HARQ-ACK bit中控制节点解出来的bit(可能只解出部分)全部指示为NACK，认为该sidelink传输失败；或者，若某个sidelink传输对应的T1/K1个Uu HARQ-ACK bit必须全部被控制节点解出(要求全部解出来)且全部指示为NACK，认为该sidelink传输失败；
若某个sidelink传输对应的Q个Uu HARQ-ACK bit中至少一个bit解出来的指示为ACK，认为这个sidelink传输成功。
进一步可选地，控制节点可以通过发送调度信令调度该终端进行重传这个sidelink传输。
一种更优的例子是，Q＝1或2或4或8。
需要说明的是，上述实施例中，都是针对T1能被K1整除的情况下映射的方式说明，针对T1不能被K1整除的情况下，可以进一步通过插入bit的方式实现映射。
方法2.2.2，对K1个sidelink HARQ-ACK bit通过重复(repeat)方式得到T1 bit结果，若该结果中一个bit指示ACK，则认为该bit对应一个Uu HARQ-ACK bit，且该bit指示ACK；若该结果指示NACK，则认为该bit对应一个Uu HARQ-ACK bit，且该bit指示NACK；基于该原则确定T1 bit的Uu HARQ-ACK信息。
例如T1＝Q*K1，上述重复的方式可以包括以下两种：
1、K1个sidelink HARQ-ACK bit中每个bit重复T1/K1次，然后级联；例如K1＝4，T1＝8，4个sidelink HARQ-ACK bit为1100，则联后的bitmap为11110000；
2、K1个bit sidelink HARQ-ACK bit信息级联T1/K1次，例如K1＝4，T1＝8，4个sidelink HARQ-ACK bit为1100，则联后的bitmap为11001100。
方法2.3：将K1个sidelink HARQ-ACK bit形成的比特序列关联的第一比特序列，确定为所述K1个sidelink HARQ-ACK bit对应的Uu HARQ-ACK信息；
具体的，上述第一比特序列可以通过查表的形式获得。在该表中可以存储由第一比特序列与另一比特序列的映射关系，该映射关系可以为一一映射，也可以为一对多的映射关系，即一个第一比特序列对应多个第一比特序列，该另一比特序列可以看做为K1个sidelink HARQ-ACK bit形成的比特序列。其中将K1个sidelink HARQ-ACK bit形成的比特序列的比特数量与第一比特序列的比特数量之间的关系可以根据实际需要进行设置，在此不做进一步的限定，例如，当K1个sidelink HARQ-ACK bit形成的比特序列为01时，关联的第一比特序列为0000。
上述第一比特序列与另一比特序列的映射关系可以通过网络侧配置、网络侧预配置、协议约定、终端间协商或其他终端指示等方式获得。
步骤2，确定用于发送上述Uu HARQ-ACK信息的目标资源，该目标资源可以为一个或者多个。
步骤3，在确定的目标资源上发送Uu HARQ-ACK信息。
假设一个PSFCH资源对应L个PUCCH资源。终端在A个PSFCH上收到了sidelink HARQ-ACK bit信息后，确定对应的Uu HARQ-ACK bit信息和PUCCH资源，并在这A*L个PUCCH资源上发送该Uu HARQ-ACK bit信息。发送方式包含以下一种:
将Uu HARQ-ACK bit信息分为A*L份，在不同的PUCCH上发送Uu HARQ-ACK bit信息不同的部分；
在每个PUCCH上发送该Uu HARQ-ACK信息的全部bit，即重复在A*L个PUCCH上发送该Uu HARQ-ACK信息。
步骤4，终端收指示进行sidelink资源分配的调度信令。
该调度信令指示多个sidelink传输进行重传(此时调度信令除了分配资源，还会指示该资源用于初传还是重传)。
一实施例中，调度信令中至少包含新数据指示(new data indicator，NDI)，指示终端是否进行重传。终端可能的行为有：
行为1：终端基于之前获取的sidelink信息中的sidelink HARQ-ACK信息实际指示的情况进行重传，即对于调度信令指示重传但是对应的sidelink HARQ-ACK信息指示ACK的传输，不进行重传，对于调度信令指示重传且对应的sidelink HARQ-ACK信息指示NACK的传输，进行重传。
行为2：直接根据调度信令指示进行重传，即调度信令指示重传，则重传信令对应所有sidelink传输；
行为3：根据发送的Uu HARQ-ACK信息进行重传，即对Uu HARQ-ACK信息NACK的传输进行重传。
对于行为1，一种实现方式是，将确定的T1 bit Uu HARQ-ACK信息repeat K1/T1次，并将repeat后的bits和K1 bit sidelink HARQ-ACK信息按照对应位求异或，或者求或，或者求和。对于计算结果中为特定值的bit对应的SL传输，终端进行重传，否则不进行重传。
进一步可选地，调度信令中分配给非特定值bit对应的sidelink传输的资源，可以被终端用于其他传输块的传输，或者用于终端确定需要重传的sidelink传输的重传。
求异或举例：更具体地，T1＝1，K1＝4 bit，1 bit Uu HARQ-ACK指示NACK。假设0表示NACK，1表示ACK，则将该bit重复4次，得到0000。而终端实际收到的4bit sidelink HARQ-ACK信息为1101,4bit分别对应sidelink上的传输块(Transport Block，TB)1、TB2、TB3和TB4。此时1101和0000按位求异或，得到的结果为1101，假设特定值为0，此时终端重传TB3，对于调度信令指示重传的TB1、TB2和TB4不进行重传。进一步可选地，调度信令中分配给TB1、TB2和TB4也可以用于TB3的重传，或者可以用于新TB的传输。
求或举例：更具体地，T1＝1，K1＝4 bit，1 bit Uu HARQ-ACK指示NACK。 假设0表示NACK，1表示ACK，则将该bit重复4次，得到0000。而终端实际收到的4 bit sidelink HARQ-ACK信息为1101,4bit分别对应sidelink上的TB1、TB2、TB3和TB4。此时1101和0000按位求或，得到的结果为1101，假设特定值为0，此时终端重传TB3，对于调度信令指示重传的TB1、TB2和TB4不进行重传。进一步可选地，调度信令中分配给TB1、TB2和TB4也可以用于TB3的重传，或者可以用于新TB的传输。
求和举例：更具体地，T1＝1，K1＝4 bit，1 bit Uu HARQ-ACK指示NACK。假设0表示NACK，1表示ACK，则将该bit重复4次，得到0000。而终端实际收到的4 bit sidelink HARQ-ACK信息为1101,4bit分别对应sidelink上的TB1、TB2、TB3和TB4。此时1101和0000按位求和，得到的结果为1101，假设特定值为0，此时终端重传TB3，对于调度信令指示重传的TB1、TB2和TB4不进行重传。进一步可选地，调度信令中分配给TB1、TB2和TB4也可以用于TB3的重传，或者可以用于新TB的传输。
需要说明的是，sidelink传输包含实际发生和未发生的传输中的至少一项，该传输为发送或者接收。
应理解，对于sidelink控制节点，sidelink信息的映射和传输与Uu控制节点的映射和传输基本一致，只是采用的目标资源不同，同时Uu HARQ-ACK信息替换为sidelink HARQ-ACK信息即可，具体可以参照上述实例的描述，在此不再赘述。
