图1示出了本公开一个示意性实施例提供的通信系统的框图，该通信系统可以包括：接入网12和终端13。
接入网12中包括若干个接入网设备120。接入网设备120可以是基站，所述基站是一种部署在接入网中用以为终端提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在长期演进(Long Term Evolution，LTE)系统中，称为eNodeB或者eNB；在5G新空口(New Radio，NR)系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能描述，会变化。为方便本申请实施例中，上述为终端提供无线通信功能的装置统称为接入网设备。
终端13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的终端(User Equipment，UE)，移动台(Mobile Station，MS)，终端(terminal device)等等。为方便描述，上面提到的设备统称为终端。接入网设备120与终端13之间通过某种空口技术互相通信，例如Uu接口。
车用无线通信技术(Vehicle to Everything,V2X)是将车辆与一切事物相连接的新一代信息通信技术，其中V代表车辆，X代表任何与车交互信息的对象， 当前X主要包含车、人、交通路侧基础设施和网络。
在本申请实施例中，终端13包括：车辆131、其它车辆132、基础设施133和行人134。
车辆对车辆(Vehicle to Vehicle，V2V)是指车辆131与其它车辆132之间的通信，本方车辆将本方的相关信息发送给对方车辆，相关信息包括行驶速度、地理位置、行驶方向和行驶状态等。
车辆对基础设施(Vehicle to Infrastructure，V2I)是指车辆131与基础设施133之间的通信，基础设施133包括车辆行驶过程中遇到的所有基础设施，包括红绿灯、公交站、大楼和隧道等建筑设施。
车辆对行人(Vehicle to Pedestrian，V2P)是指车辆131与行人134之间的通信。行人(Pedestrian)泛指行人携带的具有移动通信能力的电子设备，比如，手机和可穿戴设备，其中，可穿戴设备包括智能手环、智能手表和智能戒指等。
在本申请实施例中，将车辆131称为第一终端，将其它车辆132、基础设施133和行人134称为第二终端来举例说明，但是两者也可以互换角色，对此不加以限定。
可选地，上述通信系统可以是NR系统及后续演进系统。
在NR系统中，上行控制信息(Uplink Control Information，UCI)为承载在物理上行控制信道(Physical Uplink Control Channel，PUCCH)或者物理上行共享信道(Physical Uplink Share Channel，PUSCH)上，由UE向基站发送的控制信息。其中，UCI中包含了下行数据的应答信息(Hybrid Automatic Repeat request Acknowledge character，HARQ-ACK)，用于向基站反馈接收到的下行数据是否已经正确接收的状态，包括确认应答(Acknowledge character，ACK)和否认应答(NACK)，其中，确认应答用于表示该UE正确接收到的下行数据，NACK用于表示该UE未能接收到的下行数据。
可选地，NR上行控制信道支持五种格式，其中PUCCH格式0承载1至2比特的UCI信息，传输时，频域上占用1个资源块(Resource Block，RB)的全部12个子载波，时域上占用1至2个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号。该PUCCH格式0通过序列选择的方式承载UCI信息，即通过2 n个候选序列承载n比特的UCI信息。
可选地，通过序列选择的方式承载UCI信息能够保证上行信息传输时的单 载波特性，从而降低峰值平均功率比(Peak to Average Power Ratio，PAPR)，提高PUCCH格式0的覆盖。该UCI信息的确定过程请参考图2，如图2所示，首先基序列生成201，以及确定循环移位202，根据基序列和循环移位生成待发送序列203后，对该待发送序列进行物理资源映射204。
在NR系统中，为了提高资源利用效率，该2 n个候选序列是基于长度为12的计算机生成序列的不同循环移位值生成的，该计算机生成序列的不同循环移位是正交的，也即不同UE根据要传输的UCI信息，从2 n个候选序列中选择需要发送的循环移位，并复用同一个RB，基站从候选序列中检测UE发送的序列，从而确定UE发送的UCI。
可选地，上述PUCCH格式0的序列产生公式如下：

其中，1为UCI对应的OFDM符号索引，n为UCI占用的OFDM符号所占用的子载波的索引，

中的α用来表示不同用户序列的循环移位，该α的计算方式为：
Figure PCTCN2019116045-appb-000008
n cs为占用的OFDM符号所占用的子载波的索引，l’为偏置值，
Figure PCTCN2019116045-appb-000009
为偏置后的索引，该α是由PUCCH资源的初始循环移位m 0与HARQ-ACK特定的循环移位m cs共同决定的，对于1比特的HARQ-ACK，m cs的取值如下表一所示：
表一
HARQ-ACK值 0 1
序列循环移位参数 m cs＝0 m cs＝6
对于2比特的HARQ-ACK，m cs的取值如下表二所示：
表二
HARQ-ACK值 {0，0} {0，1} {1，1} {1，0}
序列循环移位参数 m cs＝0 m cs＝3 m cs＝6 m cs＝9
相关技术中，在NR V2X系统中，在反馈HARQ-ACK时，设计物理直连反馈信道(Physical Sidelink Feedback Channel，PSFCH)承载反馈的ACK或者NACK信息，然而，V2X系统中没有功率控制机制，当多个反馈终端反馈的UCI达到接收终端的接收功率不同时，接收功率较小的序列可能被接收功率较大的序列淹没，从而导致无法解读出接收功率较小的反馈序列。
图3是本申请一个示例性实施例提供的反馈序列的传输方法的流程图，以该方法应用于反馈终端中为例进行说明，如图3所示，该方法包括：
步骤301，接收数据信道中的数据，该数据对应有接收功率和发送功率。
可选地，在接收到该数据信道中的数据后，判断该数据是否需要反馈，当该数据需要反馈时，确定该数据是需要正向反馈、反向反馈还是正向反馈和反向反馈。
可选地，该接收功率是指反馈终端接收到该数据信道中的数据时的功率，发送功率是指接收反馈的接收终端在通过数据信道发送该数据时的功率，其中，发送功率为接收终端中预先配置的，该接收终端可以通过向反馈终端发送通知信令的方式向反馈终端通知该发送功率，接收功率为反馈终端从该数据信道中接收数据时确定得到的。
通常，接收终端与反馈终端距离越远时，发送的数据在数据信道中的路损值越大，也即发送功率与接收功率之间的差值越大。
步骤302，根据接收功率和发送功率确定反馈序列的发送次数。
可选地，根据接收功率和发送功率确定路损值，并根据路损值确定对应的发送次数。
可选地，该路损值为将发送功率减去接收功率得到的差值。
可选地，根据路损值确定发送次数时，包括如下方式中的任意一种：
第一，将路损值与反馈门限进行比对，当路损值大于反馈门限时，将第一发送次数确定为反馈序列的发送次数，当路损值不大于反馈门限时，将第二发送次数确定为反馈序列的发送次数；其中，第一发送次数的至大于第二发送次数的值；
可选地，该反馈门限为预先配置在反馈终端中的门限值，并在接收到数据 信道中的数据时，由反馈终端根据预先配置确定该反馈门限，并对路损值与该反馈门限进行比对，可选地，该反馈门限为仿真得到的门限值。
第二，将路损值与路损范围进行比对，不同的路损范围对应不同的发送次数，如：第一路损范围对应发送次数为2，第二路损范围对应发送次数为3，第三路损范围对应发送次数为4，则将该路损值与路损范围进行比对，当该路损值属于第二路损范围时，则该路损值对应的发送次数为3次。其中，第一路损范围中的路损值小于第二路损范围中的路损值，第二路损范围内的路损值小于第三路损范围内的路损值。
步骤303，以该发送次数对反馈序列进行发送。
可选地，该发送次数用于指示该反馈序列的重复发送次数，也即，根据该发送次数对该反馈序列进行序列重传。
可选地，对该反馈序列进行发送时应用的物理资源位置为预先配置的。可选地，对该反馈序列进行发送时应用的物理资源位置可以是接入网设备向反馈终端配置的，也可以是接收终端向反馈终端配置的，该接收终端为接收反馈终端反馈的反馈序列的终端。示意性的，反馈终端接收接入网设备或接收终端发送的第一配置信令，该第一配置信令中包括用于对发送反馈序列时所应用的物理资源位置进行配置的信息字段，其中接收终端为反馈终端的对端，用于接收反馈终端发送的反馈序列，后续会对接收终端处的执行方法做具体介绍，此处不再赘述。可选地，当该第一配置信令为接收终端向反馈终端发送的配置信令时，接收终端可以根据反馈特征向反馈终端进行物理资源位置的配置，该反馈特征包括距离特征和/或字节数特征，其中，距离特征用于表示接收终端和反馈终端之间的距离关系，字节数特征用于表示反馈终端反馈的反馈序列的字节数。
可选地，反馈终端发送反馈序列时应用的物理资源位置还可以根据该反馈终端与接收终端之间的距离关系和/或该反馈终端反馈的反馈序列的字节数确定，该物理资源位置还可以通过如下方式中的至少一种进行配置：
第一，接收终端根据该反馈终端与接收终端之间的距离关系和/或该反馈终端反馈的反馈序列的字节数，确定该反馈终端发送反馈序列时所应用的物理资源位置，并向该反馈终端发送第一配置信令，该第一配置信令中包括用于指示发送反馈序列时所应用的物理资源位置的信息字段；
第二，接入网设备向接收终端和反馈终端发送第二配置信令，该第二配置信令中包括用于指示反馈特征与物理资源位置之间的对应关系的信息字段，反 馈终端根据反馈特征确定发送反馈序列的物理资源位置，其中，该反馈特征包括距离特征和/或字节数特征。也即，该第二配置信令中包括用于指示距离特征与物理资源位置之间的对应关系的第一信息字段，或，该第二配置信令中包括用于指示字节数特征与物理资源位置之间的对应关系的第二信息字段，或，该第二配置信令汇总包括用于指示距离特征、字节数特征以及物理资源位置之间的对应关系的第三信息字段。当该第二配置信令中包括上述第一信息字段时，反馈终端根据与接收终端之间的距离关系确定物理资源位置；当该第二配置信令中包括上述第二信息字段时，反馈终端根据发送的反馈序列的字节数确定物理资源位置；当该第二配置信令中包括上述第三信息字段时，反馈终端根据与接收终端之间的距离关系以及反馈序列的字节数确定物理资源位置。
综上所述，本实施例提供的反馈序列的传输方法，根据数据信道的发送功率和接收功率确定该反馈序列的发送次数，并通过该发送次数对该反馈序列进行重复发送，也即，当发送功率和接收功率表示该反馈序列在传输过程中的功率损耗较大时，对该反馈序列进行多次重复传输，避免接收功率较小的序列可能被接收功率较大的序列淹没，从而导致无法解读出接收功率较小的反馈序列的问题，提高了反馈序列发送的准确率。
在一个可选的实施例中，接收终端在接收上述反馈序列时，需要通过迭代的方式对反馈序列进行解读，图4是本申请一个示例性实施例提供的反馈序列的传输方法的流程图，以该方法应用于接收终端中为例进行说明，如图4所示，该方法包括：
步骤401，在反馈序列的物理资源位置上，对反馈序列进行接收。
可选地，该物理资源位置包括时域资源位置和频域资源位置，也即，在可能接收到该反馈序列的时域资源位置和频域资源位置上对反馈序列进行接收。可选地，同一个物理资源位置上可以承载多个反馈终端反馈的反馈序列数据。
示意性的，存在k个可能反馈有反馈序列的物理资源位置，则对该k个物理资源位置上的反馈序列进行接收，k＞1。
步骤402，根据激活门限对反馈序列进行筛选，得到反馈终端反馈的控制信息。
可选地，首先对第一个物理资源位置上接收到的n个第一反馈序列进行正相关运算，得到相关结果集合，每个第一反馈序列对应相关结果集合中的一个 第一相关值，n为正整数，对相关结果集合中的第一相关值与第一门限进行比对，对第一反馈序列进行筛选，得到第一个物理资源位置上被发送的第一反馈序列，可选地，当第一相关值大于第一门限时，则该第一相关值对应的第一反馈序列为在第一个物理资源位置上被发送的第一反馈序列。将第一个物理资源位置上的第一反馈序列与后续物理资源位置上的反馈序列进行迭代筛选，得到反馈终端反馈的控制信息。
可选地，在对反馈序列进行迭代筛选时，首先将第一个物理资源位置上的n个第一反馈序列与第二个物理资源位置上的n个第二反馈序列进行叠加，得到n个叠加序列；当第i个叠加小序列的功率值大于第二门限时，从第i个叠加序列中减去对应的第i个第一反馈序列，当第i个叠加序列的功率值不大于第二门限是，将第i个第一反馈序列对应的第一相关值和第i个第二反馈序列对应的第二相关值之和与第一门限进行比对，确定第一个物理资源位置和第二个物理资源位置上被发送的反馈序列。
可选地，当第i个第一反馈序列对应的第一相关值和第i个第二反馈序列对应的第二相关值之和大于第一门限时，则确定该第i个第一反馈序列和第i个第二反馈序列为被发送的反馈序列。
可选地，针对第m个物理资源位置上的反馈序列，将该第m个物理资源位置上的n个反馈序列，与第m-1次迭代中得到的叠加序列进行叠加，得到更新后的n个叠加序列，m＞1，且m小于或者等于物理资源位置的数量；当第i个叠加序列的功率值大于第二门限时，从第i个叠加序列中减去第m-1次迭代中的第i个叠加序列，当第i个叠加序列的功率值不大于第二门限时，将第m-1次迭代中的第i个叠加序列对应的第三相关值和第m个物理资源位置上第i个反馈序列对应的第四相关值之和，与第一门限进行比对，确定m个物理资源位置上被发送的反馈序列；可选地，当迭代完成时，根据叠加序列确定反馈终端反馈的控制信息。
示意性的，该筛选过程如下：
第一步，在第一个物理资源位置上，按可能的序列结合，将反馈序列依次与接收到的序列做正相关运算，得到相关结果集合{R 1，R 2，……，R n}，其中n代表第一个物理资源位置上序列的个数；
第二步，将第一个物理资源位置上接收到的第一反馈序列对应的相关值与对应的激活门限
Figure PCTCN2019116045-appb-000010
做对比，当该相关值大于第一门限
Figure PCTCN2019116045-appb-000011
时，则表示该序列被发送 了；
第三步，将第一个物理资源位置上的第一反馈序列和第二个物理资源位置上的第二反馈序列做叠加，得到叠加序列，判断叠加序列的功率值是否超过第二门限
Figure PCTCN2019116045-appb-000012
若超过了，则从叠加序列中减去第二步判断出的第一反馈序列后，更新序列W；若没超过，则不减去第二步判断出的第一反馈序列，并重复第二步的过程，判断第一反馈序列和第二反馈序列的相关值之和是否大于第一门限
Figure PCTCN2019116045-appb-000013
并第一反馈序列和第二反馈序列的相关值之和大于第一门限
Figure PCTCN2019116045-appb-000014
时，确定该第一反馈序列和第二反馈序列为被发送的序列；
第四步，将第三个物理资源位置上的第三反馈序列与W叠加，判断叠加后的W对应的功率是否超过第二门限
Figure PCTCN2019116045-appb-000015
若超过了，则从W中减去第三步判断出的序列后，更新序列W；若没超过，则不减去第三步判断出的序列，并重复第二步的过程，根据相关值之和判断未超出发送功率的位置是否发送有反馈序列；
第五步，重复上述操作，直到所有可能的传送反馈序列的物理资源位置都被遍历过；从而得到所有可能UE的反馈信息。
综上所述，本实施例提供的反馈序列的传输方法，通过迭代的方式对反馈序列进行解读，避免接收功率较小的序列可能被接收功率较大的序列淹没，从而导致无法解读出接收功率较小的反馈序列的问题，提高了反馈序列发送的准确率。
