下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括第一终端11、第二终端12和网络设备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)、可穿戴式设备(Wearable Device)、车辆或路边单元(road side unit，RSU)等终端侧设备，需要说明的是，在本申请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，在本申请实施例中仅以5G基站为例，但是并不限定网络设备的具体类型。
可选的，在图1中，针对第一终端12到第二终端13的旁链路传输，上述第一终端11为旁链路传输的发送端或发送终端，上述第二终端12为旁链路传输的接收端或接收终端。当然在其他旁链路传输中，第一终端12还可以作为其他旁链路传输的接收端或接收终端。
为了方便理解，以下对本申请实施例涉及的一些内容进行说明：
一、长期演进(Long Term Evolution，LTE)SL资源池的时域资源
LTE SL支持15kHz。LTE SL可以使用Uu的资源进行传输，通常来说它可以使用在时分复用(Time Division Duplex，TDD)的载波上的上行(Uplink，UL)部分。LTE SL中使用参数SubframeBitmapSL-r14指示SL资源池的时域资源，该指示信息为一个位图，且位图的长度和当前使用的TDD配置有关。具体来说，大部分情况下，位图的长度和TDD配置中上行资源的数目成正比。
LTE中，一个帧为10ms，一个帧中包含10个子帧(subframe)。帧号为0-1023，理解为只会对最多1024个帧进行编号，大于1024的情况下进行编号上的环绕(wrap around)，即重新从0开始。
在确定资源池时域资源的过程中，用户会去除1024个帧用于SL同步信号的子帧、下行子帧以及特殊子帧。此时剩下子帧的数目如果不是位图长度的整数倍(例如余数N个)，那么余数部分会当做预留子帧并排除。160ms内用于SL同步信号的子帧为一个或两个或者三个。
在排除上述子帧之后的剩下子帧的数目将会是SubframeBitmapSL-r14位 图的长度的整数倍，随后对这些剩下的子帧应用该位图指示信息。具体地，每个比特和子帧一一对应。该位图指示信息在时间上不断重复。对应该位图中为1的bit的子帧属于资源池，对应0的子帧则认为不属于资源池。
二、新空口(New Radio，NR)TDD。
NR TDD配置非常灵活，一个TDD图样(pattern)中上行资源的数目可以为0个到80个。且TDD配置中可能包含1或者2个TDD pattern。一个TDD pattern的周期可能为9种。两个TDD pattern的周期(T1和T2)可能相同也可能不同。
三、旁链路混合自动重传请求(Sidelink Hybrid automatic repeat request，SL HARQ)反馈。
为了提高Sidelink传输的可靠性和有效性，NR V2X引入了SL HARQ。在SL上，发送端向接收端发送数据或TB，接收端判断数据接收是否成功，如果接收成功，接收端向发送端反馈肯定确认(Acknowledgement，ACK)，反之，反馈否定确认(Negative Acknowledgement，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，接收端(RX UE)在其PSFCH资源上反馈ACK/NACK。对于groupcast传输，反馈形式至少有两种：
选项1：RX UE只反馈NACK，对于TB解调成功的情况，RX UE不做任何反馈；选项1也可以称之为NACK only反馈机制；
选项2：RX UE在不同的资源上反馈ACK或NACK。选项2可以称为基于NACK/ACK反馈机制
上述TB传输发生在PSSCH资源上，ACK/NACK传输发生在相应的PSFCH资源上。
发送端在获取SL HARQ信息后还可以通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)或者物理上行共享信道(Physical Uplink Shared Channel，PUSCH)发送给网络设备。
四、NR SL PSFCH和物理旁链路控制通道(Physical Sidelink Control Channel，PSCCH)或PSSCH之间的对应关系。
PSFCH资源是周期性出现的，周期为periodPSFCHresource，periodPSFCHresource可以为1、2或4个SL slot。每个PSFCH时域机会(PSFCH occasion)会和periodPSFCHresource个SL slot对应，在这periodPSFCHresource个SL slot中进行的PSCCH/PSSCH传输对应的HARQ反馈会在该PSFCH occasion上的一个或者多个PSFCH资源上进行反馈，实际上就是构成了一个一对一，或多对一的PSCCH/PSSCH-PSFCH时域映射关系，从而无论是PSCCH/PSSCH发送用户还是PSCCH/PSSCH接收用户，可以知道去哪个PSFCH occasion收或发对应的SL HARQ。应理解，PSFCH occasion可以理解为PSFCH资源。
PSCCH/PSSCH slot和对应PSFCH occasion之间的间隔不小于K slots，K＝2或3。换句话说，PSCCH/PSSCH slot与对应PSFCH occasion的最小间隔为K。K的值可以通过参数MinTimeGapPSFCH指示。
PSFCH occasion可以按照周期1、2或4出现在某个slot的尾部，其中映射(mapping)的周期也为periodPSFCHresource。和位于slot m PSFCH occasion对应的slot位于slot m-K-N+1～m-K.其中N为PSFCH周期。因此对于给定K和N的PSCCH/PSSCH-PSFCH映射,互相关联的PSCCH/PSSCH slot和PSFCH slot之间间隔为K个slot到K+N-1个slot(表示为K～K+N-1)。
五、Sidelink PSCCH/PSSCH重传形式。
Sidelink支持两种PSSCH重传形式，一种是基于HARQ feedback的重传(HARQ feedback based retransmission)，一种是盲重传(blind retransmission)。其中，如果TX UE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。
六、Sidelink的资源选择。
Sidelink的资源分配方式至少有模式(mode)1和mode 2两种模式。针对mode 1，控制节点会为TX UE分配传输资源，针对mode 2，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往返时延(Round-Trip Time，RTT)时间。
七、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PSSCH传输所用。
PSFCH资源配置在SL资源池内，但是NR的上下行配置非常灵活，而且支持更多的子载波间隔(Subcarrier Spacing，SCS)，也很灵活，所以资源池配置会比LTE V2X复杂的多，那么在这种情况下一个SL资源池内SL slot数或SL资源池周期内SL slot数或者某个给定时间(例如10240ms)内SL slot数不是PSFCH周期N的整数倍。存在部分SL lot和对应的PSFCH资源之间的间隔不满足上述映射的要求。基于此提出了本申请旁链路资源处理方法和资源确定方法。
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的旁链路资源处理方法和资源确定方法进行详细地说明。
请参见图2，图2是本申请实施例提供的一种旁链路资源处理方法的流程图，该方法可以应用于发送端、接收端和网络设备，如图2所示，包括以下步骤：
步骤201，获取旁链路SL资源池配置；
步骤202，根据所述SL资源池配置，确定第一时间段内的SL资源和反馈资源；
步骤203，在所述SL资源包含满足第一条件的目标SL资源的情况下，确定操作行为；
其中，所述反馈资源包括周期为N的第一反馈资源；所述第一条件为：不存在与所述目标SL资源满足第一映射关系的第一反馈资源，或者，存在至少两个与所述目标SL资源满足第一映射关系的反馈资源，所述第一映射关系为所述第一反馈资源与所述SL资源之间的映射关系。
本实施例中，上述SL资源池配置可以由网络设备配置、协议约定或者预配置，在此不做进一步的限定，换句话说，上述获取SL资源池的配置可以理解为：接收网络设备发送的SL资源池配置、或者获取协议约定的SL资源池 配置，或者获取预配置的SL资源池配置。
根据上述第一资源池配置可以确定第一时间段内的SL资源和反馈资源，该反馈资源可以理解为PSFCH资源，在SL资源中可以设置上述反馈资源，基于该反馈资源可以传输SL资源传输的数据对应的反馈信息。
上述第一映射关系可以理解为可以用于传输PSCCH/PSSCH的slot，和，可以用于反馈这些PSCCH/PSSCH slot的反馈信息的PSFCH所在slot之间的映射关系，具体可以根据N和K的取值确定，K表示SL资源与对应反馈资源的最小间隔。应理解，可以用于传输不代表实际用于传输，即可以是候选的用于传输PSCCH/PSSCH和反馈的slot之间的映射关系，也可以是实际用于传输PSCCH/PSSCH和反馈的slot之间的映射关系。
应理解，本实施例中，发送端是指发送SL数据和/SL控制的终端，接收端是指接收SL数据和/SL控制的终端。上述第一时间段为一个周期，在实际传输时，可以包括多个的第一时间段。
可选地，不存在与所述目标SL资源满足第一映射关系的反馈资源，可以理解为在当前第一时间段内不存在与所述目标SL资源满足第一映射关系的反馈资源。也可以理解为在下一个第一时间段内不存在与所述目标SL资源满足第一映射关系的反馈资源，还可以理解为，在当前第一时间段以及下一个第一时间段内均不存在与所述目标SL资源满足第一映射关系的反馈资源。不存在与所述目标SL资源满足第一映射关系的反馈资源可以解释为：所述目标SL资源按照第一映射关系没有对应的所述第一反馈资源。
如图3所示，在一实施例中，按照K＝2，N＝2的映射，若仅在当前第一时间段内查找映射资源，则n+4、n+5和n+6均没有对应的第一反馈资源，其中n+4、n+5和n+6表示SL资源的索引。若在当前第一时间段和下一时间段查找对应的反馈资源，则n+4和n+5应该映射到n’，然而因为n’是一个新的周期(即下一个第一时间段)，其PSFCH会从n’+1开始出现，因此，此时n’上不会有PSFCH；n’+1的而PSFCH对应的SL资源在n+5和n+6，所以实际上n+5还可以对应在n’+1反馈，然而n+4依然没有对应的PSFCH。也就是说，n+4无论如何都无法找到对应的映射资源。
可选地，存在至少两个与所述目标SL资源满足第一映射关系的反馈资 源可以理解为，在当前第一时间段内存在与所述目标SL资源满足第一映射关系的反馈资源的数量大于1。也可以理解为在下一个第一时间段内存在与所述目标SL资源满足第一映射关系的反馈资源的数量大于1，还可以理解为，在当前第一时间段以及下一个第一时间段内存在与所述目标SL资源满足第一映射关系的反馈资源的数量总和大于1。本实施例中，在距离目标SL资源K～K+N-1个slot内有多个PSFCH资源，则可以认为包括至少两个对应的所述反馈资源。
如图4所示，在K＝2，N＝4，且在当前第一时间段和下一时间段查找对应的反馈资源的情况下，n+4～n+6可以找到两个符合第一映射关系的反馈资源。例如，与n+4～n+6满足第一映射关系的反馈资源包括n+8中的反馈资源和n’中的反馈资源。
上述操作行为可以理解为针对目标SL资源的处理行为，由于发送端和接收端首先确定在第一时间段内SL资源包含是否包含满足第一条件的目标SL资源，在确定第一时间段内SL资源包含满足第一条件的目标SL资源的情况下，确定操作行为，从而可以使得发送端和接收端保持理解一致。
本申请实施例通过获取SL资源池配置，根据所述SL资源池配置，确定第一时间段内的SL资源和反馈资源；在所述SL资源包含满足第一条件的目标SL资源的情况下，确定操作行为；所述反馈资源包括周期为N的第一反馈资源；所述第一条件为：所述目标SL资源按照第一映射关系没有对应的所述第一反馈资源或者至少包括两个对应的反馈资源，所述第一映射关系为所述第一反馈资源与所述SL资源之间的映射关系。这样在所述SL资源包含满足第一条件的目标SL资源的情况下，确定操作行为，从而可以使得发送端和接收端保持理解一致，避免部分SL资源没有满足第一映射关系的PSFCH，或者避免对传输对应的反馈资源理解不同，从而影响传输和/或反馈。因此，本申请实施例提高了SL传输的可靠性。
应理解，对于如何确定是否包含满足第一条件的目标SL资源的方式可以根据实际需要进行设置，例如，在一实施例中，在满足以下至少一项时，确定所述SL资源包含所述目标SL资源：
条件1，所述第一时间段内SL资源数目不为N的整数倍；
条件2，所述SL资源池配置的位图(bitmap)重复次数不为N的整数倍；
条件3，在所述第一时间段内存在第一SL资源，其中，所述第一SL资源按照所述第一映射关系对应的反馈资源位于第二SL资源，所述第二SL资源位于下一个第一时间段内，且所述第二SL资源与下一个第一时间段内第一个第一反馈资源所在的SL资源不同。
针对条件1，如图3假设第一时间段包括7个SL资源数目，且N＝2，此时，所述第一时间段内SL资源数目不为N的整数倍，从而可以确定该第一时间段内包括目标SL资源。应理解，该第一时间段包括7个SL资源数目可以理解为SL资源池配置的位图重复次数与SL资源池配置的位图对应的资源数的乘积。
针对条件2，上述SL资源池配置的位图用于确定上述SL资源，其中，位图重复次数可以理解为：在第一时间段内，位图重复的次数。例如，N＝2，位图用于配置10个SL资源，而第一时间段内对应的SL资源数目为100个，则位图的重复次数为10次，为N的整数倍；若SL资源数目为90个，则位图的重复次数为9次，不为N的整数倍，此时可以确定该第一时间段内包括目标SL资源。
针对条件3，所述第一SL资源按照所述第一映射关系对应的反馈资源可以理解为针对第一SL资源按照所述第一映射关系推导出来的虚拟反馈资源，该虚拟反馈资源所在的SL资源为第二SL资源，该第二SL资源与下一个第一时间段内第一个第一反馈资源所在的SL资源不同，即虚拟反馈资源与下一个第一时间段的第一个实际的第一反馈资源不在同一SL资源上，此时可以确定该第一时间段内包括目标SL资源。应理解，上述第二SL资源位于第一SL资源之后。
可选地，第一SL资源按照上述第一映射关系对应的反馈资源，可以理解为：第一SL资源按照上述第一映射关系推导的虚拟反馈资源所在的SL资源，该SL资源上可能实际并不包含PSFCH资源。
需要说明的是，上述SL资源可以理解为SL slot。
针对上述条件3，可以包括以下不同的理解方式：
一实施例中，针对第一SL资源按照所述第一映射关系确定的虚拟反馈 资源，该虚拟反馈资源所在的SL资源为第二SL资源，该第二SL资源位于某一SL资源之前或之后，则可以确定该第一时间段内包括目标SL资源。该某一SL资源为距离第一SL资源大于或等于K的最近一个实际的反馈资源。应理解，该第一SL资源可以理解为上述目标SL资源，或目标SL资源中的部分SL资源。
另一实施例中，针对第一SL资源，在第一SL资源之后，且距离第一SL资源大于或等于K的最近实际反馈资源与第一SL资源的距离大于N+K-1或大于N+K，则可以确定该第一时间段内包括目标SL资源。
又一实施例中，第一SL资源无法在当前第一时间段内或下一个第一时间段内找到满足第一映射关系的第一反馈资源。此时，可以确定该第一时间段内包括目标SL资源。
又一实施例中，第一SL资源基于第一映射关系与其对应的SL资源上没有第一反馈资源。此时，可以确定该第一时间段内包括目标SL资源。
又一实施例中，第一SL资源为没有完整PSCCH/PSSCH-PSFCH映射的SL资源，基于N和K的PSCCH/PSSCH-PSFCH映射无法找到对应的第一反馈资源。
进一步的，所述反馈资源还包括第二反馈资源，所述第二反馈资源用于传输所述目标SL资源对应的反馈信息，或者所述第二反馈资源用于传输上一个第一时间段内的目标SL资源对应的反馈信息。
应理解，每一个第一时间段内都设置有一个第二反馈资源。本实施例中，上述操作行为可以理解为：确定是否在第二反馈资源传输目标SL资源对应的反馈信息。
其中，上述第二反馈资源用于传输所述目标SL资源对应的反馈信息可以理解为：第二反馈资源用于反馈当前第一时间段内的目标SL资源对应的反馈信息，此时该第二反馈资源应靠近或者相对当前第一时间段的结束时间点设置。上述第二反馈资源用于传输上一个第一时间段内的目标SL资源对应的反馈信息可以理解为：前一个第一时间段内的目标SL资源的反馈信息在后一个第一时间段内进行反馈，此时，第二反馈资源应靠近或者相对第一时间段的起始时间点设置。
本实施例中，上述第二反馈资源除了可以传输目标SL资源对应的反馈信息之外，还可以传输除目标SL资源之外的其他SL资源对应的反馈信息，在此不做进一步的限定。
需要说明的是，上述第二反馈资源可以相对于第一反馈资源具有时域偏移和/或频域偏移。也就是说，所述第二反馈资源满足以下至少一项：
与所述第一反馈资源位于不同的所述SL资源；
与所述第一反馈资源具有频域偏移。
上述第二反馈资源可以为网络设备配置、协议定义或者预配置的PSFCH时域资源或者PSFCH频域资源。可选地，上述第二反馈资源可以位于当前第一时间段或者下一个第一时间段，或者位于每个第一时间段时段内。
在一实施例中，第二反馈资源与所述第一反馈资源位于不同的所述SL资源。可选地，该第二反馈资源位于所述第一时间段内的第i个SL资源，或者所述第二反馈资源位于所述第一时间段中的倒数第j个SL资源。
本实施例中，可选地，i小于或等于N-1，或者，i大于s+1且小于或等于s+N。可选地，j小于或等于N-1，或者，j大于s+1且小于或等于s+N。其中，s是第一时间段内第一个第一反馈资源的SL资源索引。
当N等于2时，倒数第j个SL资源可以理解为第一时间段的最后一个SL资源，具体如图5所示，在第一时间段内的倒数第j个SL资源为第一时间段的最后一个SL资源。第i个SL资源可以理解为第一时间段的第一个SL资源，如图6所示。
可选地，一实施例中，无论N的取值为多少，所述倒数第j个SL资源为所述第一时间段的最后一个SL资源。
进一步的，在所述第二反馈资源位于所述第一时间段中的倒数第j个SL资源的情况下，所述操作行为包括以下任一项：
所述目标SL资源对应的反馈信息在所述倒数第j个SL资源中的反馈资源上传输；
所述目标SL资源中第L个SL资源对应的反馈信息在第三SL资源中的反馈资源上传输，所述第三SL资源为：第一资源中第一个反馈资源所在的SL资源，所述第一资源与所述第L个SL资源的时域间隔大于或等于K个 SL资源，K为SL资源与对应反馈资源的最小间隔。
应理解，通常的，SL资源对应的反馈信息在该SL资源之后的SL资源中的反馈资源上传输。也就是说，所述倒数第j个SL资源位于所述目标SL资源之后。
上述目标SL资源可以包括一个或者多个SL资源，上述第L个SL资源可以理解为目标SL资源中的任一个。
本实施例中，在第一时间段内包括第一反馈资源和第二反馈资源，如图3所示，针对索引为n+5的SL资源，即可以在倒数第j个SL资源进行反馈，也可以在下一个时间段的反馈资源进行反馈，即在即SL资源(n’+1)对应的第一反馈资源传输SL资源(n+5)的反馈信息。通过定义目标SL资源中每一SL资源对应的反馈资源的位置，从而可以保证发送端和接收端对反馈资源的位置的理解保持一致。
另一实施例中，所述第一时间段的起始SL资源与下一个第一时间段的第i个SL资源之间的间隔为s+a*N个SL资源；
或者，所述第一时间段内的起始SL资源与所述第一时间段内的第i个SL资源之间的间隔为(s+a*N)mod T个SL资源；
其中，s表示所述第一时间段内第一个第一反馈资源所在的SL资源的索引，a表示所述第一时间段内第一反馈资源的数量，T表示第一时间段内SL资源数目。
本实施例中，上述i＝(s+(a)*N)mod T。可选地，在本实施例中，在第一时间段内SL资源的索引假设从0开始，若在第一时间段内SL资源的索引从1开始，则所有索引公式中的s都要加1，即s改为s+1。
可选地，在所述第二反馈资源位于所述第一时间段内的第i个SL资源的情况下，所述操作行为包括以下任一项：
所述目标SL资源中第L个SL资源对应的反馈信息在第四SL资源中的反馈资源上传输，所述第四SL资源为：第二资源中第一个反馈资源所在的SL资源，所述第二资源与所述第L个SL资源的时域间隔大于或等于K个SL资源；
所述目标SL资源中第L个SL资源对应的反馈信息在第五SL资源中的 反馈资源上传输，所述第五SL资源为：第三资源中最后一个反馈资源所在的SL资源，所述第三资源与所述第L个SL资源的时域间隔小于或等于N+K-Y个SL资源的资源中；
其中，K为SL资源与对应反馈资源的最小间隔，Y为整数。
可选地，Y的取值可以根据实际需要进行设置。在本申请各实施例中，Y可以为-1、0或1，例如，一可选方案中，Y的取值为1。
本实施例中，在下一个第一时间段内包括第一反馈资源和第二反馈资源，如图3所示，针对索引为n+5的SL资源，即可以在下一个第一时间段的第i个SL资源进行反馈，也可以在下一个时间段的第一个第一反馈资源进行反馈，即在即SL资源(n’+1)对应的第一反馈资源传输SL资源(n+5)的反馈信息。通过定义目标SL资源中每一SL资源对应的反馈资源的位置，从而可以保证发送端和接收端对反馈资源的位置的理解保持一致。
应理解，一实施例中，所述第二反馈资源与前一个第一反馈资源的时域间隔为m个SL资源，m为小于N的自然数。
本实施例中，上述m可以理解为反馈资源的密度，可选地，N＝2时，m-0或1；N＝4时，m＝0、1、2或3。其中m＝0表示对应该第二反馈资源的PSSCH和PSSCH没有对应的反馈资源。
可选地，在所述第二反馈资源与所述第一反馈资源具有频域偏移的情况下，所述第二反馈资源的频域位置包括以下至少一项：频域偏移(offset)、频域占据的资源块(Resource block，RB)和频域资源指示位图。
上述频域offset可以理解为相对于第一反馈资源配置的上边边界或者下边界或者中心的offset。频域资源指示位图中每一个比特(bit)对应一个RB，一实施例中，可以定义如果bit＝1表示该bit对应的RB属于第二反馈资源。另一实施例中，可以定义如果bit＝0表示该bit对应的RB属于第二反馈资源。
进一步的，所述第二反馈资源的时域位置为所述第一时间段的第一个第一反馈资源所在的SL资源。
可选地，在一实施例中，用户(发送端或接收端)不使用或者限制目标SL资源部分的使用，例如，所述操作行为包括以下至少一项：
在SL资源池内包含反馈资源或者启用混合自动重传请求HARQ反馈或 者指示了进行HARQ反馈的情况下，确定所述目标SL资源不属于SL资源池，或者将所述目标SL资源从所述SL资源池中排除；
确定所述目标SL资源不用于SL传输；
确定所述目标SL资源没有对应的反馈资源；
发送端不监听所述目标SL资源对应的反馈资源；
接收端不发送所述目标SL资源对应的反馈资源；
在第一传输启动或需要HARQ反馈的情况下，从所述第一传输对应的候选资源、预留资源或重选资源中排除所述目标SL资源；
在所述目标SL资源被抢占的情况下，确定所述目标SL资源优先级最低或者确定所述目标SL资源优先级最低于抢占方的优先级；
在所述目标SL资源被抢占的情况下，不比较优先级，或不触发资源重选；
确定所述目标SL资源没有对应的上报信息；
确定所述目标SL资源可用于广播传输、盲传输、盲重传或已禁用HARQ的传输。
本实施例中，确定所述目标SL资源不属于SL资源池可以理解为确定所述目标SL资源不属于SL资源，将所述目标SL资源从所述SL资源池中排除也可以理解为将所述目标SL资源从候选SL资源中排除。
可选地，一实施例中，可以认为这些目标SL资源属于预留(reserved)资源，从而将目标SL资源从SL资源池或者候选SL资源排除；另一实施例中，可以认为，这些目标SL资源和reserved资源一起排除。
可选地，从排除后的剩余资源中确定属于SL资源池的SL资源。
应理解，不比较优先级可以理解为，不比较抢占方与自己的优先级。由于不使用或者限制目标SL资源部分的使用，从而可以避免反馈出错。
需要说明的是，本申请实施例中，通过对操作行为进行定义，可以帮助对反馈资源和传输之间的理解一致，保证反馈可靠度。
一实施例中，在操作行为包括以下至少一项时，可以保证正常的SL资源的反馈：
在所述第一时间段内包含反馈资源或者启用混合自动重传请求HARQ反 馈或者指示了进行HARQ反馈的情况下，确定所述目标SL资源不属于SL资源池，或者将所述目标SL资源从所述SL资源池中排除。
另一实施例中，在操作行为包括以下至少一项时，可以保证目标SL资源的可用，提高资源的利用率：
确定所述目标SL资源不用于SL传输；
确定所述目标SL资源没有对应的反馈资源；
发送端不监听所述目标SL资源对应的反馈资源；

在所述目标SL资源被抢占的情况下，不比较优先级，或不触发资源重选。
另一实施例中，在操作行为包括确定所述目标SL资源没有对应的上报信息时，由于无需向网络设备发送上报信息，因此可以减少开销。
可选地，在一实施例中，所述操作行为包括：根据偏移配置确定所述第一反馈资源的位置。
本实施例中，对第一反馈资源的位置进行调整。上述偏移配置用于配置偏移量，该偏移配置可以理解为第一反馈资源的时域偏移。由于对第一反馈资源进行时域偏移，从而可以将目标SL资源挪到第一时间段的头部。
上述偏移配置可以是网络设备配置、预配置或协议定义的。可选地，可以基于偏移配置确定第一时间段内第一个第一反馈资源的位置，该位置可以理解为SL资源对应的索引，例如，索引为A+N*b的SL资源上设有第一反馈资源，A为偏移配置的偏移量，b为自然数。该b的取值小于或等于第一时间段除以N的值。换句话说，第一时段内第一反馈资源位于所述第一时间段 的索引为A+N*b的SL资源，A为偏移配置的偏移量，b为自然数。
可选地，上述A也可以理解为：偏移量A1+相对偏移的起始位置s1，其中s1≤N。这样，例如A1＝1,s1＝2，第一个第一反馈资源位于1+2＝3，即PSFCH位于第三个slot。
如图7所示，当A为2个SL资源，此时第一时间段内第一个第一反馈资源位于索引为2的SL资源上。上述A固定为0，即可以理解为无偏移，其中，A满足：(第一时间段SL资源数目-1)mod N+X≥A，或者min(0,((第一时间段内SL资源数mod N)-1))+X≥A，其中，X为0或者-1或者+1，mod是求余数。
可选地，所述操作行为还包括以下至少一项：
在所述第一时间段内包含反馈资源或者启用混合自动重传请求HARQ反馈或者指示了进行HARQ反馈的情况下，确定所述偏移配置对应的SL资源不属于SL资源池，或者将所述偏移配置对应的SL资源从所述SL资源池中排除；
确定所述偏移配置对应的SL资源不用于SL传输；
确定所述偏移配置对应的SL资源没有对应的反馈资源；
发送端不监听所述偏移配置对应的SL资源对应的反馈资源；
接收端不发送所述偏移配置对应的SL资源对应的反馈资源；
在第一传输启动HARQ反馈或需要HARQ反馈的情况下，从所述第一传输对应的候选资源、预留资源或重选资源中排除所述偏移配置对应的SL资源；
在所述偏移配置对应的SL资源被抢占的情况下，确定所述偏移配置对应的SL资源优先级最低或者确定所述偏移配置对应的SL资源优先级最低于抢占方的优先级；
在所述偏移配置对应的SL资源被抢占的情况下，不比较优先级，或不触发资源重选；
确定所述偏移配置对应的SL资源没有对应的上报信息；
确定所述偏移配置对应的SL资源可用于广播传输、盲重传或已禁用HARQ的传输。
本实施例中，上述偏移配置对应的SL资源可以理解为位于第一个第一反馈资源所在的SL资源以及第一时间段内在第一个第一反馈资源之前的SL资源。也可以理解为索引小于第一反馈资源所在的SL资源的前N-1个SL资源的索引对应的SL资源。
可选地，在一实施例中，用户(发送端或接收端)可以使用目标SL资源，例如，所述操作行为可以包括以下至少一项：
发送端假设目标SL资源对应的反馈信息为肯定确认ACK或否定确认NACK；
接收端不在所述目标SL资源对应的反馈资源上发送反馈信息；
确定所述目标SL资源对应的反馈资源的优先级最低或最高；
通过配置或者预配置获取所述目标SL资源对应的反馈资源的优先级；
确定所述目标SL资源对应的反馈资源无效、不存在、被丢弃或不传输；
确定所述目标SL资源对应的上报信息为ACK或NACK；
确定所述目标SL资源对应的上报信息优先级最低或最高；
通过配置或者预配置确定所述目标SL资源对应的上报信息优先级；
确定所述目标SL资源对应的上报信息的传输资源无效、不存在、被丢弃或不传输。
可选地，所述SL资源中任一个第六SL资源对应的反馈信息在第七SL资源中的反馈资源上传输；所述第七SL资源为以下任一项：
与第六SL资源的时域间隔大于或等于K个SL资源的资源中，第一个反馈资源所在的SL资源；
与第六SL资源的时域间隔小于或等于N+K-Y个SL资源的资源中，最后一个反馈资源所在的SL资源，K为SL资源与对应反馈资源的最小间隔，Y为整数。
应理解，本实施例的方案也适用于某个SL资源有一个对应的反馈资源的情况。
对于slot t，其对应的反馈资源满足以下任一项：
slot t后且距离不小于K’个slot的第一个PSFCH occasion slot，K’表示第二PSFCH资源和对应slot的最小间隔；
slot t后且距离不小于K的第一个PSFCH occasion slot。
一实施例中，如果某个或者每个第一时间段的第1个slot(即slot 0)为PSFCH occasion slot，则无论获取的SL资源配置是否满足上述整数倍或者整除要求，对于slot t，其对应的反馈资源满足以下任一项：
slot t后且距离不小于K’个slot的第一个PSFCH occasion slot，K’表示第二PSFCH资源和对应slot的最小间隔；
slot t后且距离不小于K的第一个PSFCH occasion slot。
对于slot t，其对应的反馈资源满足以下任一项：

slot t后且距离不大于N+K-1的最后一个PSFCH occasion slot。
可选地，在一实施例中，所述SL资源中任一个第六SL资源和传输所述第六SL资源的反馈信息的反馈资源之间的时域间隔小于或等于目标值，所述目标值为K+N+X或K+N-X，X为0或-1。
可选地，在一实施例中，目标反馈资源用于传输所述目标反馈资源之前的N1个SL资源对应的反馈信息；
其中，所述目标反馈资源为所述第一时间段内任一个反馈资源，所述N1个SL资源与所述目标反馈资源间隔距离大于或等于K、且小于或等于N+K-Y的SL资源中，前N1个SL资源或后N1个SL资源，Y为整数。
可选的，N1的取值等于N，其中N为PSFCH周期，例如periodPSFCHresource对应的值。应理解，本实施例的方案也适用于某个SL资源有一个对应的反馈资源的情况。
可选地，上述第一时间段，可以理解为以下任一项：10240ms、系统帧号(System frame number，SFN)周期、直接帧号(Direct frame number，DFN)周期、所述位图对应的时间段和SL资源池周期。
为了更好的理解本申请，以下结合具体实例进行详细说明。
如图3所示，按照K＝2，N＝2的映射，n+4和n+5应该映射到n’，然而因为n’是一个新的周期，其PSFCH会从n’+1开始出现，因此此时n’上不会有PSFCH，导致反馈机制出错。从而出现余数部分。该余数部分可以理解为上述目标SL资源，也可以理解为至少包括上述目标SL资源的SL资源。
对于余数部分的定义包括以下任一项：
若预设时间段内(例如10240ms或者SFN周期或者DFN周期或者SL资源池周期或者SL资源池配置对应的时间段)的(PSCCH/PSSCH)slot，无法在当前预设时间段或下一个预设时间段内找到满足第一映射关系的第一PSFCH，则存在余数部分，所述(PSCCH/PSSCH)slot属于余数部分，例如图中的n+4。
若某个预设时间段内(例如10240ms或者SFN周期或者DFN周期或者SL资源池周期或者SL资源池配置对应的时间段)的(PSCCH/PSSCH)slot，基于第一映射关系与其对应的slot上没有第一PSFCH，则存在余数部分，所述(PSCCH/PSSCH)slot属于余数部分，例如图中的n+4。
进一步可选地，在满足上述要求的第一个(PSCCH/PSSCH)slot之后N-1个(PSCCH/PSSCH)slot也认为属于余数部分(例如n+4～n+5)。
进一步可选地，位于所在预设时间段内，在满足上述要求的第一个(PSCCH/PSSCH)slot之后的(PSCCH/PSSCH)slot也认为属于余数部分(例如n+4～n+6)。
第一映射关系：基于K和N的PSCCH/PSSCH-PSFCH映射的映射关系
预设时间段内的第一PSFCH：根据N确定的PSFCH资源，具体的为PSFCH occasion(时域资源)，可以表示s+N*b，s＝0、1、···、N-1。所述预设时间段为SFN/DFN周期或者10240ms或者SL资源池bitmap配置对应的时间段。
方案1：网络设备配置或者协议定义或者厂商预配置SL资源时，包含以下至少一种情况，此时存在余数部分：
情况1，存在某个或者某些预设时间段内SL资源数目不是反馈资源周期的整数倍的情况。例如，10240ms内SL资源数目不是反馈资源周期的整数倍的情况，例如SL资源池配置对应的时间段内SL资源数目不是反馈资源周 期的整数倍的情况。
情况2，某个或者某些预设时间段内SL资源池配置bitmap重复(映射)次数不是反馈资源周期的整数倍的情况。例如，10240ms内SL资源池配置bitmap重复(映射)次数不是反馈资源周期的整数倍的情况。
情况3，某个或者某些第一预设时间段时长和第二预设时间段内SL资源池配置bitmap重复(映射)次数的乘积R*T不是反馈资源周期的整数倍的情况(或者说不可以被整除)。例如，SL资源池bitmap配置对应的时间段内的SL资源数目R和10240ms内SL资源池配置bitmap重复(映射)次数T的乘积不是反馈资源周期的整数倍的情况。
情况4，对于某个SL slot t，如果按照该资源池PSCCH/PSSCH-PSFCH mapping，其对应的‘可能’PSFCH occasion在相对slot t的L个SL slot后，且该‘可能’PSFCH的slot位于下一个预设时间段(例如下一个SFN/DFN周期)，且该‘可能’PSFCH的slot在其所属下一个预设时间段内的相对于该预设时间段起点的slot index小于s或者大于s，则说明存在余数部分，例如该SL slot t没有(满足PSCCH/PSSCH-PSFCH mapping)对应的PSFCH资源。
情况5，对于某个SL slot t，如果按照该资源池PSCCH/PSSCH-PSFCH mapping，其对应的‘可能’PSFCH occasion在相对slot t的L个SL slot后，然而在SL slot t后且和SL slot t距离大于等于K的最近一个实际的PSFCH occasion所在slot t’，‘可能’PSFCH occasion在slot t’之前或之后，则说明存在余数部分，例如该SL slot t没有(满足PSCCH/PSSCH-PSFCH mapping)对应的PSFCH资源。
情况6，对于某个SL slot t，如果按照该资源池PSCCH/PSSCH-PSFCH mapping，在SL slot t后且和SL slot t距离大于或等于K的最近一个实际的PSFCH occasion所在slot和slot t的距离大于N+K-1或大于N+K，则说明存在余数部分，例如该SL slot t没有(满足PSCCH/PSSCH-PSFCH mapping)对应的PSFCH资源。
情况7，若某个预设时间段内(例如10240ms或者SFN周期或者DFN周期或者SL资源池周期或者SL资源池配置对应的时间段)的(PSCCH/PSSCH)slot，无法在当前预设时间段或下一个预设时间段内找到满足第一mapping的 第一PSFCH，则存在余数部分。
情况8，若某个预设时间段内(例如10240ms或者SFN周期或者DFN周期或者SL资源池周期或者SL资源池配置对应的时间段)的(PSCCH/PSSCH)slot，基于第一mapping与其对应的slot上没有第一PSFCH，则存在余数部分。
可选地，(上述不满足整数倍或整除要求的)预设时间段中存在余数部分可以认为余数部分属于某个目标时间段，目标时间段具体包含以下任一项：
在预设时间段中，例如在某个或者每个给定时间段(例如10240ms)或SFN/DFN周期内，最后一个SL资源池周期；
在预设时间段中，例如在某个或者每个给定时间段(例如10240ms)或SFN/DFN周期或SL资源池周期内，最后一次SL资源池bitmap配置(例如SL resource pool bitmap configuration)映射时对应的逻辑或者物理时间；

某个或者每个DFN/SFN周期；
某个或者每个10240ms；
某个或者每个SL资源池bitmap配置(例如SL资源池位图配置)映射时对应的逻辑或者物理时间。
其中，某个可以理解为当前或者下一个，例如某个DFN周期，可以理解为当前DFN周期或者下一个DFN周期。
可选地，上述预设时间段无法完成完整PSCCH/PSSCH-PSFCH映射部分的slot称为余数部分，或者无法根据基于K和N的PSCCH/PSSCH-PSFCH mapping找到对应PSFCH的slot称为余数部分。也可以理解为，无法按照PSCCH/PSSCH-PSFCH映射找到PSFCH的slot称为余数部分，例如图3所示的slot n+4。或者理解为是无法按照PSCCH/PSSCH-PSFCH映射找到PSFCH的slot自身以及其之后的一个或者多个slot。例如可以理解为图3中的slot  n+4和slot n+5，或者理解为slot n+4到slot n+6。
为了处理余数部分，有如下方法。
方法1-1，为预设时间段内的余数部分引入第二PSFCH资源(时域PSFCH资源)。
可选地，网络设备配置或者协议定义或者厂商预配置上述预设时间段内(余数部分)的第二PSFCH资源时域位置t’，包含：
t’位于该预设时间段或者每个预设时段内的倒数第j个SL slot，i≤N-1；可选地，倒数第j个且不为第一PSFCH的SL slot为t’；可选地，倒数第一个SL slot，如图5所示。
t’位于下一个预设时间段或者每个预设时段内的SL slot i，i<N-1。例如，在i＝0时，如图6所示。
可选地，t’位于下一个预设时间段或者每个预设时段内的第b’个slot：
假设资源池中正常PSFCH的slot表示为s、s+N、s+2N···。如果s+a*N的位置超过预设时间段边界(例如超过了SFN/DFN边界)，且超过边界(即进入下一个预设时间段)的slot数量为b’个并且b’不为N，则在每个预设时间段内的第b’个slot为t’，即下一个预设时间段或者每个预设时段的第b’个slot包含第二PSFCH资源。从而对于某个预设时间段内的slot n(即第n-1个slot)。
公式可以表示为：b’＝(T-s-1)mod N或者b’＝(N-(T-s-1)mod N)或者编号为(T-s-1)mod N-1的slot为t’或者编号为(N-(T-s-1)mod N)-1的slot为t’。其中，T为预设时间段内SL资源数目。
可选地，PSFCH时域资源的密度m或m为余数部分的第二PSFCH资源和前一个PSFCH资源的时域间隔
可选地，0≤m<N，例如，N＝2时，m＝0或1；N＝4时，m＝0、1、2或3。如果m＝0表示对应该slot的PSSCH和PSSCH slot没有对应的反馈资源。
可选地，所述第二PSFCH资源和前一个第一PSFCH资源的距离为m；
第二PSFCH资源和对应slot的最小间隔K’。
可选地，K’＝min(K，m)。或者K’＝min(K，N)
可选地，K’≤K。
如图5所示，第二PSFCH资源可以放在slot n+6。此时slot n+5的反馈可以位于slot n+6对应的第二PSFCH资源，或者slot n’+1对应的第一PSFCH资源。对应于一个SL slot t，具体的可以满足如下规则之一：
如果SL slot t属于余数部分，则slot t在该预设时间段内的最后一个slot进行反馈；即slot n+6；
选择在slot t后且距离slot t不小于K’个slot的第一个PSFCH资源进行反馈；即slot n+6
选择在slot t后且距离slot t不小于K个slot的第一个PSFCH occasion进行反馈；即slot n’+1。
如图6所示，第二PSFCH资源可以放在slot n’。此时slot n+5的反馈可以位于slot n’对应的第二PSFCH资源，或者slot n’+1对应的第一PSFCH资源。对应于一个SL slot t，具体的可以满足如下规则之一：
选择slot t后且距离不小于K个slot的第一个PSFCH occasion进行反馈；即slot n’；
选择slot t后且距离不大于N+K-1的最后一个PSFCH资源进行反馈；即slot n’+1。
可选地，每个预设时间段的第1个slot(slot 0)为PSFCH occasion slot，则无论获取的SL资源配置是否满足上述整数倍或者整除要求。对于slot t,其对应的反馈资源位于slot t后且距离不小于K’个slot的第一个PSFCH occasion slot或者slot t后且距离不小于K的第一个PSFCH occasion slot。
方法1-2，为预设时间段内的余数部分引入第二PSFCH资源(频域PSFCH资源)。
网络设备配置或者协议定义或者厂商预配置上述预设时间段内(余数部分)的第二PSFCH资源，具体包含以下至少一项：
PSFCH频域位置f’，f’包括频域偏移、频域占据的资源块RB和频域资源指示位图中的至少一项；
PSFCH时域位置t’，t’为下一个预设时间段内的第一个PSFCH occasion所在的slot，如图8所示，在n’+1处配置第二PSFCH资源用于余数部分反馈。
由于通过频域偏移设置第二PSFCH资源，提高了资源利用率和灵活性，且不影响资源分配流程和HARQ反馈流程。
可选地，一实施例中，所述SL资源中任一个第六SL资源和传输所述第六SL资源的反馈信息的反馈资源之间的时域间隔小于或等于目标值，所述目标值为K+N+X或K+N-X，X为0或-1。
方法2：不使用或者限制余数部分的使用。可选地，余数部分对应的目标slot包含以下至少一项：
在SL资源池内包含反馈资源或者启用混合自动重传请求HARQ反馈或者指示了进行HARQ反馈的情况下，不属于SL资源池，或者所述目标slot从所述SL资源池中排除；
不用于SL传输；
没有对应的反馈资源；
发送端不监听目标slot对应的反馈资源；
接收端不发送目标slot对应的反馈资源；
在第一传输启动或需要HARQ反馈的情况下，从所述第一传输对应的候选资源、预留资源或重选资源中排除目标slot；
在所述目标SL资源被抢占的情况下，目标slot优先级最低或者确定目标slot优先级最低于抢占方的优先级；
在目标slot被抢占的情况下，不比较优先级，或不触发资源重选；
没有对应的上报信息；
可用于广播传输、盲传输、盲重传或已禁用HARQ(disabled)的传输。
方法2-1：通过增加PSFCH资源时域offset来将余数部分挪到预设时间段的头部。
网络设备配置或者协议定义或者厂商预配置PSFCH资源时，包含offset配置，基于offset确定PSFCH资源。
例如，所述PSFCH资源存在于offset+N*b的位置，b为自然数，且b小于或等于预设时间段时长除以N的取整值。该取整值可以理解为向上取整或向下取整获得的值。
可选地，还可以配置额外的K’，K’≥K，例如图7所示，K’＝K+offset。
可选地，offset对应的SL slot包含以下至少一项：不用于实际传输、没有对应的反馈资源、PSSCH发送用户不监听反馈、PSSCH接收用户不发送反馈、从需要HARQ的TB对应的候选资源或预留资源或重选资源中排除、被抢占时不比较优先级或不触发资源重选、没有对应的SL上报信息。
方法3，可以使用余数部分(例如，可以用于需要HARQ反馈的TB的传输)，例如可以包括以下至少一项：
PSSCH发送端不监听对应的‘反馈slot’；
PSSCH发送端假设余数部分PSSCH传输对应的反馈为ACK或NACK；
PSSCH接收端不在对应的‘反馈slot’上反馈；
余数部分对应的反馈资源的优先级最低或最高；
余数部分对应的反馈资源的优先级可以配置或者预配置；
所述余数部分对应的反馈资源无效、不存在、被丢弃或不传输；
余数部分对应的SL上报信息为ACK或NACK；
余数部分对应的SL上报信息优先级最低或最高；
余数部分对应的SL上报信息优先级可配置或者可以预配置；
余数部分对应的SL上报信息的传输资源(PUCCH和/或PUSCH)无效、不存在、被丢弃或不传输。例如，一个SL配置授权(SL configured grant)的某个周期的资源包含了余数部分中的至少一个资源，则该配置授权(Configured grant，CG)周期的PUCCH不传输。可选地，所述SL配置授权为SL configured grant type1。
可选地，一个预设时间段内的第一个反馈资源时域位置在该预设时间段的第一个时域资源，例如第一个PSFCH occasion在预设时间段的第一个SL slot，从而PSFCH occasion位于该预设时间段内的s+N*b slot,b＝0、1、2···取整值。该取整值为预设时间段时长除以N的取整值，其中，取整值可以为向上取整得到的值，或者向下取整得到的值。
可选地，根据PUSCH/PUCCH关联的PSFCH occasion slot推出和PSFCH occasion slot对应的PSSCH/PSCCH slot的位置。
假设所述PSFCH occasion slot位于slot s’，包括以下情况之一：
情况1，所述PSSCH/PSCCH slot位于距离s’之前且距离s’不少于K个 slot且不大于N+K-Y个slot的slot中最晚的N个slot。可选地，如果在根据PSSCH/PSCCH slot确定其对应的反馈slot时，如果对于PSSCH/PSCCH slot t，确定其对应的PSFCH occasion在slot t后且距离不小于K个slot的第一个PSFCH occasion时，适合使用该情况来通过PSFCH slot确定对应的PSSCH/PSCCH slot。
情况2，所述PSSCH/PSCCH slot位于距离s’之前且距离s’不少于K个slot且不大于N+K-Y个slot的slot中最早的N个slot。可选地，如果在根据PSSCH/PSCCH slot确定其对应的反馈slot时，如果对于PSSCH/PSCCH slot t，确定其对应的PSFCH occasion在slot t后且距离不大于N+K-Y的最后一个PSFCH资源时，此时适合使用该情况来通过PSFCH slot确定对应的PSSCH/PSCCH slot。
可选地，Y＝-1或者0或者1。
可选地，一种实现方式中，余数部分属于SL预留资源的部分，从而在排除SL预留资源时余数部分也被排除，或者被认为不属于SL资源。或者另外一种实现方式中，余数部分和或SL预留资源被排除，或者被认为不属于SL资源。
余数部分和或SL预留资源被排除的一种实施例通过如下步骤实现:
一、在SLSS信号占据的资源，没有包含满足预设要求的UL资源的资源，余数部分中的至少一项排除后剩下的资源中确定SL资源池的资源，例如排除SLSS信号占据的资源，没有包含满足预设要求的UL资源的资源，余数部分后的资源表示为
Figure PCTCN2021095720-appb-000001
其中N slss为预设时间内资源总数Q内SLSS的资源数目，N dssf为预设时间内资源总数Q内没有包含满足预设要求的UL资源的资源，N remainder是预设时间段内没有满足映射的反馈资源的SL资源数目。例如Q可以为10240ms内的slot数目，可选地，为物理slot数，进一步可选地，为采用SL SCS表示的物理slot数。包含满足预设要求的上行资源的资源指的是只包含上行符号的资源，或者包含足够上行符号的资源，或者包含上行符号且第一个上行符号不大于符号X 最后一个上行符号不小于符号X+Y的资源。
二、对于一个slot l r,其中l r(0≤r＜(Q-N slss-N dssf-N remainder))，如果这个slot满足
Figure PCTCN2021095720-appb-000002
其中m＝0,...,N reserved-1，N reserved＝(Q-N slss-N dssf-N remainder)mod L bitmap.其中L bitmap是资源池配置bitmap的长度，则它属于预留资源。
可选地，通过上述步骤排除了余数部分和预留资源，在剩余资源中确定SL资源。注意本方法是先排除余数资源再排除预留资源的一个示意，并不表示唯一顺序，其他顺序，例如先排除预留资源再排除余数资源或者同时排除都可以。
请参见图9，图9是本申请实施例提供的另一种资源确定方法的流程图，该方法可以应用于发送端、接收端和网络设备，如图9所示，包括以下步骤：
步骤901，获取旁链路SL资源池配置；
步骤902，根据所述SL资源池配置确定SL资源和周期性的反馈资源；其中，所述反馈资源用于反馈所述SL资源对应的反馈信息，所述SL资源池配置满足以下至少一项：
第二时间段内SL资源数目为所述反馈资源的周期N的整数倍；
第三时间段内所述SL资源池配置的位图重复次数为N的整数倍；
相邻的两个反馈资源的时域间隔小于或等于N；
相邻的两个反馈资源的时域间隔小于或等于K，K为SL资源与对应反馈资源的最小间隔；
所述反馈资源位于索引为s+N*b的SL资源的情况下，第四时间段内倒数第N-s个SL资源为反馈资源，s表示所述第四时间段内第一个第一反馈资源所在的SL资源的索引，b为自然数。
上述相邻的两个反馈资源可以理解为时域相邻的两个反馈资源。可选地，上述N小于或等于K。
本实施例中，上述SL资源池配置可以由网络设备配置、协议约定或者预配置，在此不做进一步的限定，换句话说，上述获取SL资源池的配置可以理 解为：接收网络设备发送的SL资源池配置、或者获取协议约定的SL资源池配置，或者获取预配置的SL资源池配置。
可选地，上述第二时间段与第一时间段可以为相同的时间定义，也可以为不同的时间定义，例如，一实施例中，所述第二时间段为以下任一项：10240ms、系统帧号SFN周期、直接帧号DFN周期、所述位图对应的时间段和SL资源池周期。所述第三时间段为以下任一项：10240ms、SFN周期、DFN周期和SL资源池周期。
其中，SL资源池的位图对应的时间段可以理解为：SL资源池bitmap对应的逻辑或者物理时长，SL资源池bitmap中置1的bit对应的逻辑或者物理时长，或者，SL资源池bitmap中置0的bit对应的逻辑或者物理时长。
SL资源池周期可以理解为：例如SL资源池的位图映射的周期，或，SL资源池的位图重复预设次数所对应的逻辑或者物理周期，SFN周期，或，SFN周期，或，10240ms，或，SL资源池的bitmap对应的逻辑或者物理周期，SL资源池的bitmap中置1的bit对应的逻辑或者物理周期，或者SL资源池的bitmap中置0的bit对应的逻辑或者物理周期。例如，一个SL资源池周期内SL资源数目为PSFCH周期的整数倍。例如，配置或者预配置或者定义SL资源池周期为P，则在某个或者每个P内进行SL资源池的位图的重复连续映射，每进入下一个P，重新开始映射SL资源池的位图。例如每进入一个新的周期，都从索引为0的SL资源开始映射。
SFN周期可以理解为：最小SFN到最大SFN之间的时间，例如10240ms。
DFN周期可以理解为：最小DFN到最大DFN之间的时间，例如10240ms。
例如，一个DFN或SFN周期内SL资源池bitmap配置重复映射次数为PSFCH周期的整数倍。
上述10240ms可以理解为给定的一段时间。
可选地，所述第二时间段为10240ms、SFN周期、DFN周期或所述SL资源池周期的情况下，所述第二时间段内SL资源数目反馈资源的周期的整数倍包括：
第二时间段内所述位图重复次数与所述位图对应的时间段内SL资源数目的乘积，为所述反馈资源的周期的整数倍。
例如，位图对应的时间段内SL资源数目为14个SL slot，第二时间段为10240ms，且第二时间段内SL资源池配置bitmap重复(映射)次数为98次，假设该资源池内PSFCH周期为4，显然第二时间段内所述位图重复次数与所述位图对应的时间段内SL资源数目的乘积为4的倍数。
可选地，对于所述反馈资源位于索引为s+N*b个SL资源的情况下，第四时间段内倒数第N-s个SL资源为反馈资源可以理解为，如果第四时间段内正常的PSFCH位于s+N*b，第四时间段内的倒数的N-s个slot是PSFCH slot。例如：
针对s＝0，倒数第N个slot是PSFCH slot；
针对s＝1，倒数第N-1个slot是PSFCH slot；
针对s＝N-2，倒数第2个slot是PSFCH slot；
针对s＝N-1，最后1个slot是PSFCH slot。
本申请实施例中，通过SL资源池配置确定SL资源和反馈资源，且SL资源池配置满足以下至少一项：第二时间段内SL资源数目为所述反馈资源的周期N的整数倍；第三时间段内所述SL资源池配置的位图重复次数为N的整数倍；相邻的两个反馈资源的时域间隔小于或等于N；相邻的两个反馈资源的时域间隔小于或等于K；所述反馈资源位于索引为s+N*b的SL资源的情况下，第四时间段内倒数第N-s个SL资源为反馈资源，s表示所述第四时间段内第一个第一反馈资源所在的SL资源的索引，b为自然数。这样可以保证所有的SL资源都存在满足第一映射关系的PSFCH，因此提高了SL传输的可靠性。
可选地，上述第二时间段内SL资源的数目，可以理解为第二时间段时长。也可以称之为，第二时间段内的SL slot数目，或者为第二时间段的物理时长，比如包含的ms数目，包含的s数目，包含的帧数等。换句话说，在本实施例中，所述SL资源数目为SL时隙数目或物理时间单元的数量。
具体地，第二时间段内的SL资源数目可以是第二时间段内SL资源池配置bitmap中为1的bit对应的资源数目，或者，第二时间段内的SL资源数目可以是第二时间段内SL资源池配置bitmap中为0的bit对应的资源数目。
进一步地，第二时间段内的SL资源数目是第二时间段内与PSFCH资源 所在的SL资源池的资源池配置bitmap中为1的bit对应的slot的数目。SL资源可以解释为SL slot。
例如，第二时间段为SL资源池周期或10240ms或DFN/SFN周期，存在资源池1和资源池2，资源池1的PSFCH周期为2，资源池2的PSFCH周期为4，则第二时间段内对应资源池1的资源池配置bitmap中为1的bit的slot数目为2的倍数，第二时间段内对应资源池2的资源池配置bitmap中为1的bit的slot数目为4的倍数。
可选地，所述SL资源中任一个第六SL资源和传输所述第六SL资源的反馈信息的反馈资源之间的时域间隔小于或等于目标值，所述目标值为K+N+X或K+N-X，X为0或-1。
可选地，目标反馈资源用于传输所述目标反馈资源之前的N1个SL资源对应的反馈信息；
其中，所述目标反馈资源为所述反馈资源中任一个反馈资源，所述N1个SL资源与所述目标反馈资源间隔距离大于或等于K、且小于或等于N+K-Y的SL资源中，前N1个SL资源或后N1个SL资源，Y为整数。
需要说明的是，第二时间段内SL资源数目是反馈资源周期的整数倍，用户的行为有以下至少一项：
用户期望或假设SL资源池bitmap配置对应的时间段内的SL资源数目R是反馈资源周期的整数倍；
更具体地，用户期望或假设第二时间段内SL资源数目是反馈资源周期的整数倍，用户期望或假设第二时间段内SL资源池配置bitmap重复(映射)次数T是反馈资源周期的整数倍；
