具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图及具体实施例对本发明进行详细描述。
下面先对与本发明实施例中相关的一些概念进行说明如下。
1、旁链路(sidelink，译为副链路、侧链路，边链路、直接通信链路等，简称SL)混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)反馈
为了提高Sidelink传输的可靠性和有效性，新空口(New radio，NR)车到万物(Vehicle to everything，V2X)引入了SL HARQ。在SL上，发送节点向接收节点发送数据/传输块(transport block，TB)，接收节点判断数据接收是否成功，如果接收成功，接收节点向发送节点反馈确认应答(ACK)，反之，反馈非确认应答(NACK)。
SL支持单播(unicast)，组播(groupcast)和广播(broadcast)传输，其中unicast和groupcast传输需要支持SL HARQ反馈。对于unicast传输，接收终端(RX UE，也称接收端)在其物理旁链路反馈信道(Physical Sidelink Feedback Channel，PSFCH)资源上反馈ACK/NACK。对于groupcast传输，反馈形式至少有两种：情况1、RX UE分享PSFCH资源，且RX UE只反馈NACK，对于TB解调成功的情况，RX UE不做任何反馈；情况2、RX UE占用不同的PSFCH资源，RX UE在各自的资源上反馈ACK/NACK。
上述TB传输发生在物理旁链路共享信道(Physical Sidelink Shared Channel，PSSCH)资源上，ACK/NACK传输发生在相应的PSFCH资源上(即corresponding PSFCH)。
2、Sidelink物理旁链路控制信道(Physical Sidelink Control Channel，PSCCH)/PSSCH重传形式
Sidelink支持两种PSSCH重传形式，一种是基于HARQ反馈(feedback)的重传(HARQ feedback based retransmission)，一种是盲重传(blind retransmission)。其中，如果发送终端(TX UE，也称发送端)采用HARQ feedback based retransmission，RX UE需要对TX UE传输的PSSCH做HARQ feedback，TX UE根据HARQ feedback决定是否重传PSSCH；如果TX UE采用blind retransmission的重传方式，TX UE直接在重传资源上进行PSSCH传输。
3、Sidelink的资源选择
Sidelink的资源分配方式至少有模式一(mode 1)和模式二(mode 2)两种模式。针对mode 1模式，控制节点会为TX UE分配传输资源，针对mode2模式，TX UE进行自主选择传输资源。
至少针对mode 2，为了保证PSSCH重传的资源出现在TX UE解调反馈信息之后，规定任意两次选择的PSSCH传输资源间的时间间隔需要大于HARQ往返时间(Round-TripTime，RTT)(即下述Z＝a+b为所述HARQ RTT时间)。
其中，a是第一个资源的PSSCH传输的最后一个符号的结束与相应PSFCH接收的第一个符号的开始之间的时间间隔，由资源池配置的MinTimeGapPSFCH和periodPSFCHresource的更高层参数确定；b是PSFCH接收时间、PSFCH接收和处理时间或PSFCH接收和处理以及重传准备所需的时间，包括必要物理信道的多路复用和任何TX-RX/RX-TX切换时间，由UE实现确定。
这里还需要说明的是，若PSSCH传输资源没有相应的PSFCH，那么Z值可以假设0、无限小值或无限大值。
图1和2为a和b的示意图，其中，图1中b值较小，PSFCH接收和处理/重传的准备能够在PSFCH所在时隙(slot)内完成；图2中b值较大，PSFCH接收和处理时间/重传的准备时间需要跨slot。图1为常规情况，但不排除图2出现的可能。其中，图1和图2中的斜线填充框为PSCCH/PSSCH传输资源，横线填充框为PSFCH传输资源。
4、Sidelink的资源预留
TX UE会对其分配的资源进行资源预留(预留分为周期性预留和非周期性预留)，预留资源为以后的PSCCH和/或PSSCH传输所用。另外，对于周期性预留，每个周期的预留资源用于传输同一个TB。
虽然mode 2资源选择时，尽量避免所述问题出现。但是，TX UE进行资源预留时(例如，周期性资源预留)，难免造成相邻两次的PSSCH传输资源不满足HARQ RTT时间，如图3和图4所示(本发明中仅示例问题出现的部分情况，不排除其他问题出现的情况)。
对于图3所示的情况，相邻两次预留的PSSCH资源对应到同一个PSFCH  occasion。对于图4所示的情况，虽然相邻的两次预留对应到不同的PSFCH occasion，但是TX UE处理前一次PSSCH反馈的PSFCH所需时间较长，在下一次PSSCH传输资源到来时，无法为PSSCH重传做出准备。图3所示的情况为常规情况，但不排除图4所示的情况出现的可能。其中，图3和图4中的斜线填充框为PSCCH/PSSCH传输资源，横线填充框为PSFCH传输资源
本发明针对现有的SL传输，无法始终保持下一次PSSCH传输的资源出现在发送终端解调反馈信息之后，造成资源浪费，反馈信息冗余等的问题，提供一种资源确定、传输、反馈方法、发送端和接收端。
如图5所示，本发明实施例提供一种资源确定方法，应用于发送端，包括：
步骤501，确定第一传输块TB的第二目标资源的时域位置位于第一目标资源对应的反馈信息所在的时域位置之后；
其中，所述第一目标资源为物理旁链路共享信道(PSSCH)传输资源和/或物理旁链路控制信道(PSCCH)传输资源；所述第二目标资源为PSSCH传输资源和/或PSCCH传输资源；本发明实施例中所提到的第一目标资源对应的反馈信息指的是：第一目标资源上传输的数据所对应的PSFCH反馈，该第一目标资源上传输的数据指的是PSSCH信息和/或PSCCH信息。
需要说明的是，该发送端指的是在SL通信过程中，进行PSSCH和/或PSCCH发送的终端。
进一步需要说明的是，该第一TB指的是发送端在进行信息传输时，需要传输的任一TB，该第二目标资源以及第一目标资源均指的是第一TB位于不同传输时刻的资源。
需要说明的是，本发明实施例中所说的发送端确定第一TB的第二目标资源的时域位置位于第一目标资源对应的反馈信息所在的时域位置之后可以为：发送端从控制节点获取资源分配信息，得到第一TB的第二目标资源的时域位置位于第一目标资源对应的反馈信息所在的时域位置之后，也可以为：发送端自己进行资源分配，得到第一TB的第二目标资源的时域位置位于第一目标资源对应的反馈信息所在的时域位置之后。
具体地，本发明实施例中，步骤501可以采用如下至少一项实现方式：
A11、在进行资源分配时，分配第一TB的第一目标资源和第二目标资源的时间间隔至少大于或大于等于混合自动重传请求往返时间HARQ RTT、且对位于第一TB所在的时域资源之后周期性预留的其他TB的传输资源，每个周期内的预留传输资源之间的时间间隔均至少大于或大于等于HARQ RTT；
需要说明的是，此种实现方式中以及本发明实施例中后续所提到的HARQ RTT等于a+b，其中，a为第一目标资源的PSSCH传输和/或PSCCH传输的最后一个符号的结束时刻与相应的PSFCH接收的第一个符号的开始时刻之间的时间间隔；b为PSFCH接收时间、PSFCH接收和处理时间或PSFCH接收和处理以及重传准备所需的时间。
需要说明的是，此种情况中所说的资源分配主要指的是发送端进行资源选择。
也就是说，在此种方式下，发送端在进行资源选择时，需要保证任一TB的任意两次传输资源(即指的是PSSCH传输资源和/或PSCCH传输资源)的时间间隔至少要大于(本发明实施例中所说的大于代表的数据符号为＞)HARQ RTT，或者是说，发送端在进行资源选择时，需要保证任一TB的任意两次传输资源(即指的是PSSCH传输资源和/或PSCCH传输资源)的时间间隔至少要大于等于(本发明实施例中所说的大于等于指的是大于或等于，即≥)HARQ RTT；进一步地，对位于第一TB所在的时域资源之后周期性预留的其他TB的传输资源，每个周期内的预留传输资源也均需要满足上述的条件，而对于周期间的预留传输资源则无需满足上述的条件。
此种方式也可以理解为：获取控制节点为发送端进行资源分配时所分配的资源，所述发送端对所分配的资源的期待为任一TB的任意两次传输资源(即指的是PSSCH传输资源和/或PSCCH传输资源)的时间间隔至少要大于(本发明实施例中所说的大于代表的数据符号为＞)HARQ RTT，或者是说，获取控制节点为发送端进行资源分配时所分配的资源，所述发送端对所分配的资源的期待为任一TB的任意两次传输资源(即指的是PSSCH传输资源和/或PSCCH传输资源)的时间间隔至少要大于等于(本发明实施例中所说的大于等于指的是大于或等于，即≥)HARQ RTT；进一步地，对位于第一TB所在的时域资源之后周期性预留的其他TB的传输资源，每个周期内的预留 传输资源也均需要满足上述的条件，而对于周期间的预留传输资源则无需满足上述的条件。
需要说明的是，此种方式能够避免上述图3和图4中情况的出现。
A12、在进行资源分配时，分配第一TB的第一目标资源和第二目标资源的时间间隔至少大于或大于等于物理旁链路反馈信道(PSFCH)周期；
需要说明的是，此种情况中所说的资源分配主要指的是发送端进行资源选择。
也就是说，在此种方式下，发送端在进行资源选择时，需要保证任一TB的任意两次传输资源(即指的是PSSCH传输资源和/或PSCCH传输资源)的时间间隔至少要大于(本发明实施例中所说的大于代表的数据符号为＞)PSFCH周期，或者是说，发送端在进行资源选择时，需要保证任一TB的任意两次传输资源(即指的是PSSCH传输资源和/或PSCCH传输资源)的时间间隔至少要大于等于(本发明实施例中所说的大于等于指的是大于或等于，即≥)PSFCH周期。
此种方式也可以理解为：获取控制节点为发送端进行资源分配时所分配的资源，所述发送端对所分配的资源的期待为任一TB的任意两次传输资源(即指的是PSSCH传输资源和/或PSCCH传输资源)的时间间隔至少要大于(本发明实施例中所说的大于代表的数据符号为＞)PSFCH周期，或者是说，获取控制节点为发送端进行资源分配时所分配的资源，所述发送端对所分配的资源的期待为任一TB的任意两次传输资源(即指的是PSSCH传输资源和/或PSCCH传输资源)的时间间隔至少要大于等于(本发明实施例中所说的大于等于指的是大于或等于，即≥)PSFCH周期。
A13、在进行资源预留时，第一TB的第一目标资源和第二目标资源的时间间隔至少大于或大于等于HARQ RTT；
需要说明的是，此处的第一TB指的是未来某一次或多次TB(即待传输的TB)，发送端在之前TB传输时，预留资源给待传输的TB。
也就是说，在此种方式下，发送端在进行资源预留时，需要保证任一TB的任意两次传输资源(即指的是PSSCH传输资源和/或PSCCH传输资源)的时间间隔至少要大于HARQ RTT，或者是说，发送端在进行资源预留时，需 要保证任一TB的任意两次传输资源(即指的是PSSCH传输资源和/或PSCCH传输资源)的时间间隔至少要大于等于(本发明实施例中所说的大于等于指的是大于或等于，即≥)HARQ RTT。
此种方式也可以理解为：获取控制节点为发送端进行资源分配时所分配的资源，所述发送端对所分配的资源的期待为任一TB的任意两次传输资源(即指的是PSSCH传输资源和/或PSCCH传输资源)的时间间隔至少要大于HARQ RTT，或者是说，获取控制节点为发送端进行资源分配时所分配的资源，所述发送端对所分配的资源的期待为任一TB的任意两次传输资源(即指的是PSSCH传输资源和/或PSCCH传输资源)的时间间隔至少要大于等于(本发明实施例中所说的大于等于指的是大于或等于，即≥)HARQ RTT。
A14、在进行资源预留时，若第一TB所在的进程支持周期性预留，配置所述第一TB所在的进程的资源预留周期为PSFCH周期的整数倍，所述进程为旁链路进程(SL process)或旁链路预留进程(SL booking process)；
也就是说，在此种方式下，发送端在进行资源预留时，针对同一TB所在的进程的资源预留的周期为PSFCH周期的整数倍。
此种方式也可以理解为：获取控制节点为发送端进行资源分配时所分配的资源，所述发送端对所分配的资源的期待为针对同一TB所在的进程的资源预留的周期为PSFCH周期的整数倍。
A15、获取控制节点为发送端进行资源分配时所分配的资源，所述发送端对所分配的资源的期待为第一TB的第一目标资源和第二目标资源的时间间隔至少大于或大于等于HARQ RTT；
也就是说，在此种方式下，发送端需要获取控制节点为发送端进行资源分配时所分配的资源，所述发送端对所分配的资源的期待为第一TB的第一目标资源和第二目标资源的时间间隔至少大于HARQ RTT，或者是说，发送端需要获取控制节点为发送端进行资源分配时所分配的资源，所述发送端对所分配的资源的期待为第一TB的第一目标资源和第二目标资源的时间间隔至少大于等于(本发明实施例中所说的大于等于指的是大于或等于，即≥)HARQ RTT。
A16、在进行资源分配时，分配第一TB的第一目标资源和第二目标资源 的时间间隔至少大于或大于等于最大的HARQ RTT、且对位于第一TB所在的时域资源之后周期性预留的其他TB的传输资源，每个周期内的预留传输资源之间的时间间隔均至少大于或大于等于HARQ RTT；
需要说明的是，因HARQ RTT的取值为一个范围，在实际使用时，存在HARQ RTT的最大值和最小值，此处指的是发送端在进行资源分配时，需要保证第一TB的第一目标资源和第二目标资源的时间间隔至少大于最大的HARQ RTT(即大于HARQ RTT的最大取值)，或者是说，发送端在进行资源分配时，需要保证第一TB的第一目标资源和第二目标资源的时间间隔至少大于等于(本发明实施例中所说的大于等于指的是大于或等于，即≥)最大的HARQ RTT(即大于或等于HARQ RTT的最大取值)；进一步地，对位于第一TB所在的时域资源之后周期性预留的其他TB的传输资源，每个周期内的预留传输资源也均需要满足预留传输资源之间的时间间隔均至少大于或大于等于HARQ RTT，而对于周期间的预留传输资源则无需满足每个周期间的预留传输资源之间的时间间隔均至少大于或大于等于HARQ RTT。
需要说明的是，本发明实施例至少适用于基于HARQ反馈的PSSCH重传和/或PSCCH重传，也就是说，本发明实施例中的所述第二目标资源和所述第一目标资源用于进行基于HARQ反馈的PSSCH重传和/或PSCCH重传。
还需要说明的是，本发明实施例中的上述实现方式中，针对同一个旁链路进程或旁链路预留进程不能同时用于基于HARQ反馈的重传和盲重传；这个限制尤其针对于上述的实现方式A13和A14。
需要说明的是，本发明实施例，从发送端进行资源确定角度，对资源确定进行限定，以避免相邻PSSCH传输和/或PSCCH传输不满足HARQ RTT的时间限制，尽可能避免了资源的浪费。
如图6所示，本发明实施例提供一种发送端600，包括：
确定模块601，用于确定第一传输块TB的第二目标资源的时域位置位于第一目标资源对应的反馈信息所在的时域位置之后；
其中，所述第一目标资源为物理旁链路共享信道PSSCH传输资源和/或物理旁链路控制信道PSCCH传输资源；所述第二目标资源为PSSCH传输资源和/或PSCCH传输资源。
