下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供资源处理方法、装置、终端和存储介质进行详细地说明。
请参见图2，图2是本申请实施例提供的一种资源处理方法的流程图， 如图2所示，包括以下步骤：
步骤201、第一终端执行目标操作，其中，所述目标操作包括如下至少一项：
检测冲突资源；
针对冲突资源，执行冲突处理操作；
依据第二终端的资源进行SL资源选择，所述第二终端为所述第一终端的物理旁链路信道的对端。
上述第一终端可以是SL的发送端，又可以是SL的接收端。上述第二终端也可以是SL的发送端或者接收端(发送端或者接收端统称为对端)，且第一终端可以对应多个第二终端，例如：一个第二终端为SL的发送端，另一个第二终端为SL的接收端。上述物理旁链路信道可以是物理旁链路控制信道(physical sidelink control channel，PSCCH)、物理旁链路共享信道(physical sidelink shared channel，PSSCH)或者物理旁链路反馈信道(Physical Sidelink Feedback channel，PSFCH)。
上述检测冲突资源可以是，检测上述第一终端相关的资源是否存在冲突资源。例如：检测第一终端的用于SL发送的资源、第一终端的用于SL接收的资源和上行链路(uplink，UL)资源等中至少一项是否包括冲突资源。
本申请实施例中，上述冲突资源包括如下至少一项：
SL资源之间的冲突；
SL资源与非SL资源之间的冲突。
上述SL资源是指用于SL传输的资源，例如：PSCCH资源、PSSCH资源、PSFCH资源。
上述SL资源之间的冲突可以是，多个SL资源存在部分或者全部重叠。
上述非SL资源可以是第一终端与网络设备进行通信的资源，例如：上行发送资源(UL TX资源)或者下行接收资源(DL RX资源)。或者上述非SL资源可以是WIFI资源、蓝牙资源、紫峰(zigbee，一种低速短距离传输的无线网上协议)资源等。
上述SL资源与非SL资源之间的冲突可以是，SL资源与非SL资源存在部分或者全部重叠。
需要说明的是，本申请实施例中，冲突资源可以是指至少两个资源存在资源重叠或者潜在资源重叠。其中，潜在资源重叠是指在至少两个资源在某一时时刻检测是资源重叠，但在另一些时刻检测可能不存在资源重叠，例如：某一些终端对资源进行了重选，导致在重选之前是存在资源重叠，但重选后可能不存在资源重叠。另外，资源重叠或者潜在资源重叠可以是指在资源在时间上部分或者全部重叠，例如：存在相同的时隙/子时隙/符号/子帧；资源重叠也可以是频域资源重叠或者时频资源重叠。
另外，本申请实施例中，冲突资源也可以称作碰撞冲突资源。
上述针对冲突资源，执行冲突处理操作可以是，在检测到冲突资源，或者接收到通知冲突资源的信令的情况下，针对冲突资源执行冲突处理操作，例如：丢弃冲突资源、丢弃冲突资源对应的传输或者执行资源重选等等。
需要说明的是，本申请实施例中，上述冲突资源可以是通过检测确定的，也可以是第二终端的信令通知的。进一步，第一终端检测到冲突资源后，也可以向第二终端通知该冲突资源。
上述依据第二终端的资源进行SL资源选择可以是，选择与第二终端的资源不重叠的SL资源，或者选择与第二终端的资源对应的反馈资源不重叠的SL资源。
本申请实施例中，通过上述步骤可以实现检测冲突资源、针对冲突资源，执行冲突处理操作和依据第二终端的资源进行SL资源选择中的至少一项，这样可以提高终端的SL的能力。例如：通过检测冲突资源可以确定第一终端相关的冲突资源，从而提高第一终端的资源检测效果；由于依据第二终端的资源进行SL资源选择，这样可以降低或者避免资源冲突，以提高SL的传输可靠性；由于针对冲突资源执行冲突处理操作，从而可以提高SL的传输可靠性，以及还可以降低或者避免传输冲突发生，提高资源利用率。
作为一种可选的实施方式，所述检测冲突资源，包括：
所述第一终端依据资源信息，检测冲突资源；
其中，所述资源信息用于表示如下至少一项：
所述第一终端的资源、至少一个第二终端的资源。
其中，上述第一终端的资源可以是第一终端选择的资源或者第一终端预 留的资源，或者第一终端需要占用的资源，例如：第一终端选择的用于SL发送的资源。上述第二终端的资源可以是第二终端选择的资源或者第二终端预留的资源，或者第二终端需要占用的资源，例如：第二终端选择的用于SL发送的资源。
其中，至少一个第二终端的资源可以是第二终端通过信令通知的资源，例如：在第二终端在选择资源后，通过广播信令或者单播信令向第一终端通知第二终端选择的资源。
上述第一终端依据资源信息，检测冲突资源可以是，检测第一终端的资源中是否存在冲突资源，或者检测第一终端的资源和至少一个第二终端的资源之间是否存在冲突资源。
该实施方式中，依据资源信息可以准确地检测出是否存在冲突资源。
可选的，所述第一终端依据资源信息，检测冲突资源，包括：
所述第一终端依据所述资源信息和至少一个所述第二终端的标识，检测冲突资源。
上述至少一个所述第二终端的标识可以用于标识资源对应的第二终端，这样通过上述资源信息和至少一个第二终端的标识可以准确地确定与第一终端存在资源冲突的第二终端，以进一步提高检测效果。
可选的，所述至少一个第二终端的资源包括：
通过所述第一终端接收的SL控制信息确定的至少一个第二终端的资源，其中，所述SL控制信息包括如下至少一项：
资源预留信息、预留资源关联的终端标识。
其中，上述资源预留信息可以是PSCCH/PSSCH资源预留信息，上述预留资源关联的终端标识可以是，预留资源的目标标识(destination ID)或者预留资源的源标识(source ID)。上述预留资源可以包括非周期和/或周期预留的资源。
该实施方式中，通过上述SL控制信息可以准确地确定至少一个第二终端的资源。
另外，上述SL控制信息可以是通过解调PSCCH和PSSCH中的至少一项得到的SL控制信息。
例如：在上述第二终端为向第一终端发送PSCCH/PSSCH的发送端的情况下，第一终端对第二终端发送的SL控制信息解调获取PSCCH/PSSCH资源预留信息和PSCCH/PSSCH资源关联的目标标识，以判断PSCCH/PSSCH资源的PSCCH/PSSCH是否发送向第一终端。如第一终端解调SL控制信息(例如：PSCCH)中的第一个信道状态信息字段(1 st stage SCI)获取资源预留信息；解调PSSCH中的第二个信道状态信息字段(2 nd stage SCI)获取资源关联的目标标识，以判断资源是否向第一终端发送。
需要说明的是，本申请实施例中，非周期的预留资源可以与对应的终端关联，即通过非周期预留的资源可以判断出该资源传输的目标终端，从而在SL控制信息可以不携带的目标标识。当然，本申请实施例中，在一些场景中周期预留的资源也可以与对应的终端关系，即通过周期预留资源可以判断出该资源传输的目标终端。另外，本申请实施例中，通过目标标识可以获知非周期预留或者周期预留的资源上的信息发送是否向第一终端发送，当然，也不排除结合高层目标标识，进行联合判断，对此本申请实施例不作限定。
又例如：在上述第二终端为接收第一终端所发送的PSCCH/PSSCH的接收端的情况下，第一终端进行SL控制信息解调获取PSCCH/PSSCH资源预留信息和所述资源关联的源标识，以判断该PSCCH/PSSCH资源对应的PSCCH/PSSCH是否源自上述第二终端。例如：解调PSCCH中的第一个信道状态信息字段(1 st stage SCI)获取资源预留信息，其中，预留资源可以包括非周期和/或周期预留的资源，且至少对于非周期性预留的资源，可判断预留资源是否来自第一终端；以及还可以解调PSSCH中的第二个信道状态信息字段(2 nd stage SCI)获取预留资源关联的源标识，以判断预留资源是否来自第一终端。例如：至少可由源标识获知非周期预留的资源上的信息发送来自于第一终端，当然，也不排除结合高层源标识，进行联合判断，对此本申请实施例不作限定。
需要说明的是，本申请实施例中并不限定通过SL控制信息确定至少一个第二终端的资源，例如：在一些场景中，还可以通过高层信令获知至少一个第二终端的资源。

上述第一终端需要在所述冲突资源上接收TB可以是，上述第一终端在上述冲突资源前确定不能成功解调上述TB，因此，第一终端需要继续在冲突资源上进行接收，那么冲突实际存在，即存在上述传输冲突。或者，上述第一终端需要在所述冲突资源上接收TB可以是，第一终端在上述冲突资源前不能确定是否成功解调该TB(例如：仍有待使用的TB传输资源)，第一终端可能需要继续在冲突资源上进行接收，具体是否需要继续上冲突资源上进行接收决于协议约定/配置/预配置/第一终端自行判断。也就是说，第一终端在上述冲突资源前不能确定是否成功解调该TB的情况下，上述传输冲突是否存在取决于协议约定/配置/预配置/第一终端自行判断。
上述第一终端需要在所述冲突资源上发送TB可以是，第一终端在冲突资源之前不能成功发送上述TB，第一终端需要继续在冲突资源进行发送，导致存在传输冲突，例如：PSSCH发送(PSSCH TX)与PSSCH接收(PSSCH  RX)双工冲突，或者PSFCH发送(PSFCH TXs)与PSFCH接收(PSFCH RX)双工冲突实际存在。
或者，上述第一终端需要在所述冲突资源上发送TB可以是，第一终端在冲突资源之前不能确定是否成功发送上述TB(仍有待使用的TB传输资源)，第一终端根据协议约定/配置/预配置/自行判断确定继续在冲突资源进行发送，导致存在传输冲突。也就是说，第一终端在冲突资源之前不能确定是否成功发送上述TB的情况下，上述传输冲突是否存在取决于协议约定/配置/预配置/第一终端自行判断。
另外，第一终端可以通过HARQ反馈状态判断是否成功发送上述TB，例如：对于单播或者组播(unicast/groupcast)收到ACK，则确定TB发送成功，对于组播,在一些场景中没收到NACK可以确定TB发送成功。
上述第一终端需要在所述冲突资源上接收或者发送HARQ反馈可以是，对于PSFCH收发的双工冲突，第一终端判断该冲突的PSSCH资源上的TB传输是否使能了HARQ反馈，或者该TB是否需要反馈HARQ-ACK/NACK。如果使能了或者该TB需要反馈HARQ-ACK/NACK，则终端作为发送端的情况下，需要接收HARQ反馈，终端作为接收端的情况下，需要发送HARQ反馈。
可选的，在如下一项的情况下确定不存在所述传输冲突：
所述第一终端在所述冲突资源之前已经成功解调TB；
所述第一终端在所述冲突资源之前能成功发送TB；
所述第一终端在所述冲突资源上不需要接收HARQ反馈；
所述第一终端在所述冲突资源上不需要发送HARQ反馈；
其中，所述TB为所述冲突资源对应的TB，所述HARQ反馈为所述冲突资源对应的HARQ反馈。
该实施方式中，若第一终端在所述冲突资源之前已经成功解调TB，则确定实际冲突不存在，即不存在上述传输冲突。例如：第一终端进行TB接收时，多次TB传输中的某次TB传输在冲突的PSCCH/PSSCH资源上进行，或者在造成PSFCH冲突的PSCCH/PSSCH上进行。如果UE在所述冲突资源之前成功解调了该TB，则第一终端无需继续在冲突资源上进行接收，那么冲突 实际不存在。
该实施方式中，若第一终端在所述冲突资源之前能成功发送TB，则确定实际冲突不存在，即不存在上述传输冲突。例如：当第一终端进行TB发送时，多次TB传输中的某次TB传输会在冲突的资源上进行，或者在造成PSFCH冲突的PSCCH/PSSCH上进行。如果第一终端在冲突资源之前能成功发送该TB，则第一终端无需继续在冲突资源进行发送，那么冲突实际不存在。
上述第一终端在所述冲突资源上不需要接收或者发送HARQ反馈可以是，对于PSFCH收发的双工冲突，第一终端判断该冲突的PSSCH资源上的TB传输是否使能了HARQ反馈，或者该TB是否需要反馈HARQ-ACK/NACK，如果没有使能HARQ反馈/不允许反馈HARQ-ACK/NACK，那么该冲突实际不存在，即不存上述传输冲突。
上述实施方式中，可以实只有在存在传输冲突，即实际上存在冲突的情况下，才执行冲突处理操作，而对于存在冲突资源但不存在上述传输冲突，即实际上不存在冲突的情况下，不执行冲突处理操作，以节约终端的功耗。
作为一种可选的实施方式，所述目标操作还包括：
检测所述冲突资源前所述冲突资源对应的TB最后一次传输是否传输成功。
上述冲突资源对应的TB可以是，在上述冲突资源为PSCCH/PSSCH资源的情况下，上述TB为需要在该PSCCH/PSSCH资源上需要传输的TB，或者在上述冲突资源为PSFCH资源的情况下，上述TB为造成PSFCH资源冲突的PSCCH/PSSCH资源传输的TB。
上述最后一次传输可以是指在TB多次传输的情况下，判断在上述冲突资源之前上述TB最后一次传输是否传输成功。例如：配置TB传输3次，而上述冲突资源是TB的第3次传输，则上述是判断TB的第第2次传输是否传输成功。
该实施方式中，由于检测上述最后一次传输是否传输成功，这样更加有利用于终端对冲突资源的检测，以进一步提高终端的检测效果，例如：当上述最后一次传输成功时，可以直接认为上述冲突资源不存在传输冲突。
作为一种可选的实施方式，所述针对冲突资源，执行冲突处理操作，包 括：
满足如下至少一项的情况下，针对所述冲突资源，执行冲突处理操作：

上述冲突资源对应的传输信息可以是，冲突的PSCCH/PSSCH资源中的传输信息，或者造成PSFCH冲突的PSCCH/PSSCH资源上的传输信息。
例如：第一终端判断冲突的PSCCH/PSSCH资源上(或者造成PSFCH冲突的PSCCH/PSSCH资源上)的传输类型，当检测到第一终端/第二终端在PSCCH/PSSCH资源上传输的传输类型为目标传输类型时才执行冲突处理操作。
上述目标QoS可以是协议定义、预配置或者网络指示的。另外，本申请实施例中，QoS可以是优先级或者其他服务质量信息。下面为QoS为优先级进行举例说明：

第一终端检测到第一终端在冲突的PSCCH/PSSCH资源(或者造成PSFCH冲突的PSCCH/PSSCH资源)上的传输优先级高于/不低于(或者低于/不高于)预定义/配置/预配置的阈值，才执行冲突处理操作。
上述在所述冲突资源之后，所述冲突资源对应的TB不存在传输资源可以是，冲突的PSCCH/PSSCH资源后(或者造成PSFCH冲突的PSCCH/PSSCH资源后)检测是否仍存在该TB的传输资源，如果不存在，则执行冲突处理操作。
或者，上述在所述冲突资源之后，所述冲突资源对应的TB不存在传输资源可以是，第一终端检测到第二终端采用多个传输资源进行TB传输，如果第一终端检测到上述冲突资源之后仍存在TB的重传资源，则不执行冲突处理操作，如果第一终端检测到上述冲突资源之后不存在TB的重传资源，则执行冲突处理操作。
或者，上述在所述冲突资源之后，所述冲突资源对应的TB不存在传输资源可以是，第一终端采用多个传输资源进行TB传输，如果上述冲突资源之后仍存在TB的重传资源，则不执行冲突处理操作，如果上述冲突资源之后存在TB的重传资源，则执行冲突处理操作。
上述第一终端无法在所述冲突资源上发送多个物理旁链路反馈信道PSFCH可以是，对于PSFCH同发冲突，第一终端判断是否能够同时发送冲突的多个PSFCH，如果不能，则执行冲突处理操作，如果能，则不执行冲突处理操作。
上述第一终端在所述冲突资源上有至少一个PSFCH的发送功率低于或者等于门限值可以是，对于PSFCH同发冲突，如果第一终端发送某个PSFCH的功率低于(或者不高于)门限值，则执行冲突处理操作。
上述实施方式中，可以实现在满足上述至少一项的情况下，才执行冲突处理操作，以节约终端的功耗，提高终端的传输可靠性。如果上述至少一项不满足时，则不执行冲突处理操作。进一步的，上述实施方式还可以与上述 传输冲突的实施方式结合实现，例如：存在上述传输冲突，且满足上述至少一项的情况下，针对所述冲突资源，执行冲突处理操作，否则，不执行冲突处理操作。
作为一种可选的实施方式，所述针对冲突资源，执行冲突处理操作，包括：
在所述冲突资源为首次指示为所述第一终端的SL资源的情况下，在第一条件下针对冲突资源执行冲突处理操作；或者

下面通过6个场景对本申请实施例提供的冲突处理操作进行举例说明：
场景一
该场景图3所示，第一终端为UE1，UE0和UE2为第二终端，具体可以包括如下：
UE1检测到冲突资源后，采取如下冲突处理操作：
UE1通知目标对端(UE0或UE2)重选冲突的PSCCH/PSSCH资源，或通知目标对端UE(UE2)放弃所述PSCCH/PSSCH发送/采用其它非冲突资源进行发送，目标对端可执行相应行为。
其中，在存在多个满足条件的对端的情况下，UE1可以向部分对端发送触发信令。
例如，UE1向传输某种特定传输类型(如unicast)的对端发送触发信令；
例如，UE1向传输QoS要求高/低(优先级高于/不低于/低于/不高于某阈值)的对端发送触发信令；
例如，UE1向最近发送预留信令预留所述冲突资源的一个/多个对端UE发送触发信令；
例如，UE1向冲突较多的UE发送触发信令。UE0的当前TB传输跟UE2的传输冲突，而UE2的TB传输跟UE0、3、4、5的传输都冲突，可以向UE2 发送触发信令，从而减少通知重选次数；
例如，UE1向传输TB对应时延(PDB)较长的UE发送触发信令，保证时延较短的成功发送。
另外，还可以限定上述部分对端的个数，例如最大个数/最小个数/个数的范围等。
上述触发信令可以触发对端执行相应的冲突处理操作。
可选的，如果UE1判断对端对冲突资源又进行了资源重选(例如pre-emption等触发的重选)，则无需发送该通知，其中，UE1可以通过显式指示或者隐式的方式确定对端对冲突资源是否进行了资源重选。
场景二

UE1通知目标对端UE(UE2)重选造成PSFCH冲突的PSCCH/PSSCH资源，或通知目标对端UE(UE2)放弃PSCCH/PSSCH发送/采用其它非冲突资源进行发送，目标对端UE可执行相应行为。
在存在多个满足条件的对端的情况下，可以如下：
UE1向部分对端UE发送触发信令。例如，向传输某种特定传输类型的对端发送触发信令，向传输QoS要求高/低(优先级高于/不低于/低于/不高于某阈值)的UE发送触发信令
可以限定所述部分对端的个数，例如最大个数/最小个数/个数的范围等

若UE1放弃了PSCCH/PSSCH接收，UE1可继续执行上述1-2的操作；
若UE1放弃PSCCH/PSSCH接收，则可以按如下规则进行HARQ反馈，以便恢复对端的重传：

对于组播模式1(groupcast option 1)，反馈NACK
对于组播模式2(groupcast option 2)，反馈NACK，或者不反馈信息，如在DTX场景中不反馈信息。
1-4、对于图5所示的右边的场景，对于PSFCH冲突，UE1根据规则放弃冲突的PSFCH的发送/接收。例如，协议约定/控制节点配置/预配置放弃‘发送’/‘接收’，或根据优先级放弃‘发送’/‘接收’(例如放弃低优先级的收/发)

2-1、重选冲突的PSCCH/PSSCH资源(或者造成PSFCH冲突的PSCCH/PSSCH资源)，或放弃所述PSCCH/PSSCH发送/采用其它非冲突资源进行发送；
2-2、通知目标对端(UE1)重选冲突的PSCCH/PSSCH资源(或者造成PSFCH冲突的PSCCH/PSSCH资源)，或通知目标对端UE(UE1)放弃所述 PSCCH/PSSCH发送/采用其它非冲突资源进行发送，目标对端UE可执行相应行为。

1-2、UE1放弃冲突的UL发送或PSCCH/PSSCH接收，或者冲突的UL发送或造成PSFCH冲突的PSCCH/PSSCH接收。例如，协议约定/控制节点配置/预配置放弃发送/接收，或根据优先级放弃发送/接收(例如放弃低优先级的信息)；
其中，若UE1放弃了UL TX发送，UE1可继续执行该场景中的上述1-1；
若UE1放弃了PSCCH/PSSCH接收，UE1可继续执行该场景中的上述1-2；
若UE1放弃PSCCH/PSSCH接收，按如下规则进行HARQ反馈，以便恢复对端的重传；

针对上述传输冲突该场景可以执行如上述场景一至场景五中任一种冲突处理操作。
需要说明的是，上述6个场景中UL TX可替换成LTE SL TX/RX，或任意其他的技术的传输(例如WIFI，蓝牙，zigbee…)。另外，上述6个场景仅是对本申请实施例提供的冲突处理操作进行举例说明，本申请实施例中的冲突处理操作并不限定是上述6个场景中的冲突处理操作。

反复进行资源重选步骤直到排除所述第二终端的资源或排除所述第二终端的资源对应的PSFCH关联的资源。
所述第二终端的资源可以是第二终端占用的PSCCH/PSSCH时域资源，PSCCH/PSSCH频域资源，或者PSCCH/PSSCH时频资源；
