第二类是在sensing窗口中监听到了其他UE发送的SA(Scheduling Assignment，调度分配)，根据从SA中获知的周期和资源预约信息，如果预约的资源与候选资源交叠，或者与候选子帧之后的1，2，…，10*counter-1次发送资源交叠，且根据SA测量到的PSSCH-RSRP(物理直通链路共享信道-参考信号接收功率；PSSCH：Physical Sidelink Shared Channel，物理直通链路共享信道；RSRP：Reference Signal Received Power，参考信号接收功率)高于门限值，则相应的候选资源需要被排除；
如果经step2排除后，剩余资源比例低于20％，则将门限值提升3dB，重新执行排除过程，直至剩余资源比例达到或高于20％为止；
Step3：对候选资源进行S-RSSI(Sidelink-Received Signal Strength Indication，直通链路-接收的信号强度指示)测量和排序，选择出S-RSSI测量值最低的20％资源，由高层从上述20％候选资源中进行资源选择。
3GPP Release15的直通链路发送模式4在3GPP Release14的Sensing+SPS的资源选择机制基础上，增加了多载波资源选择的处理，即：
高层为物理层提供候选资源池，物理层按照3GPP Release14的Sensing机制的step1和step2的资源排除，对候选资源进行S-RSSI测量和排序，选择出S-RSSI测量值最低的20％资源上报给高层，高层对针对以下超出UE发送能力的子帧进行排除：
(a)TX chains(发送链路)的数量小于配置的发送载波数量；
(b)UE不能支持给定band(频带)的合并；
(c)TX chain切换时间。
之后，选择出发送资源。
如发送资源导致UE不能满足RF(Radio Frequency，射频)需求，例如 由于PSD imbalance(PSD不平衡；PSD：Power Spectral Density，功率谱密度)，UE对每个载波独立执行资源选择，如果资源选择的结果导致同时发送次数超过UE发送能力，则重新执行资源选择过程，直至资源选择结果可以被UE所支持。
3GPP RAN(Radio Access Network，无线接入网)#80会议通过了3GPP V2X第三阶段的NR(New Radio Access Technology，新空口技术)V2X SI(Study Item)的立项，在研究方向中包括新的物理层结构设计。潜在地，NR V2X中可支持灵活的参数集(numerology)，也就是支持时域上不同的时隙长度和频域上不同的SCS(Sub-carrier Spacing，子载波间隔)。
然而，在V2X直通链路通信方式下，同一频带内，由于半双工影响，其中一个载波上进行发送，其他载波上将无法进行接收，从而造成该时域资源上所有业务包均无法被接收，影响V2X通信可靠性。这种情况在NR V2X支持灵活参数集的情况下，以及考虑NR V2X和LTE V2X共存时，会显著加剧，也就是如图2所示，当载波2上的一个时隙上进行业务包的发送时，将造成载波1上的1个时隙、载波3上的2个时隙以及载波4上的4个时隙无法进行接收，显著影响系统性能。
另一方面，在同一频带内，对于受到半双工影响的相同时域上，由于NR V2X潜在地可支持灵活的参数集配置，因此当UE上具有数量有限的PA(power amplifier，功率放大器)时，则可能会在共享PA时造成相位不连续，导致发送功率波动，使系统性能显著下降。
因此在现有技术中，当NR V2X可以支持灵活的参数集配置时，会受到半双工的影响，以及PA数量有限时、在时隙不一致的情况共享PA造成PA相位不连续，而导致系统性能显著下降。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图本申请作进一步地详细描述，显然，所描述的实施例仅仅是本申请的一部分实施例，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做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。
实施例一：
为解决由于受到半双工的影响，当NR V2X可以支持灵活的参数集配置时，会因在业务包发送时，造成多个时隙无法接收，导致系统性能下降的问题，本申请实施例提供了一种资源选择方法，如图3所示，所述方法包括以下步骤：
步骤S301：当多个业务包到达，针对每个业务包，依次将每个业务包作为当前业务包，判断当前业务包获得的候选资源集合是否至少为2个。
步骤S302：如果当前业务包获得的候选资源集合为至少2个，则根据每个候选资源集合对应的参数集，将参数集中时隙长度最小的参数集对应的候选资源集合确定为该业务包的目标资源集合。
具体地，在本申请实施例中，候选资源集合包括为以下至少一种：载波；资源池；部分带宽。候选资源集合的可以是载波、资源池、部分带宽其中的至少一种或者各种组合方式；例如，如果每个载波上仅配置一个资源池，该资源池覆盖整个载波上的全部频域资源，则候选资源集合可以以载波为粒度或者以资源池为粒度；如果每个载波上配置多个资源池，则确定的候选资源集合以资源池为粒度；同理，如果每个载波上配置多个部分带宽，则确定的候选资源集合以部分带宽为粒度。资源池或者部分带宽相关的参数可通过网络侧配置或者预配置参数获得。
其中，由于在本申请实施例中，候选资源集合为UE根据网络侧的配置确定的或UE根据预配置参数确定的，因此UE可根据网络侧的配置或者自身预配置参数确定业务包能够获得的候选资源集合，所以当UE检测到有业务包到 达时，UE即可判断出针对该业务包的候选资源集合的数量是否为多个，如果是，为了最大程度地避免半双工的影响，那么在为该业务包进行资源选择时，则会优先为该业务包选择参数集中时隙长度最小的候选资源集合。
也就是如图4所示，假如针对某个业务包，如果网络侧的高层将载波1、载波2以及载波3作为该业务包的发送载波，其中如果载波1的参数集为子载波间隔15KHz，载波2的参数集为子载波间隔为30KHz，对应的时隙长度为0.5ms，载波3的子载波间隔为60KHz，对应的时隙长度为0.25ms。由于载波3的时隙长度最小，因此当在载波3上发送业务包时，对于载波1和载波2来说，均只有1个时隙会受到半双工的影响而无法进行数据接收，可以达到系统性能目的，因此UE则会将载波3最终确定为该业务包的发送载波。
因此，在本申请实施例中，在NR V2X引入灵活参数集，进行多载波/资源池/部分带宽发送时，通过采用在集中时隙上进行发送的方式，可大大降低半双工影响，从而提升系统性能。
实施例二：
由于针对当前业务包的候选资源集合可以为多个，那么该候选资源集合中则可能会存在参数集相同的候选资源集合，因此在针对当前业务包确定的目标资源集合的数量也可能是多个，所以在上述实施例的基础上，在本申请实施例中，根据每个候选资源集合对应的参数集，将参数集中时隙长度最小的参数集对应的候选资源集合确定为该业务包的目标资源集合之后，如果参数集中时隙长度最小的参数集存在多个，则按照以下方法中的至少一种从时隙长度最小的参数集对应的候选资源集合中进行目标集合的确定：
随机选择一个候选资源集合；
选择频点最低的候选资源集合；
选择优先级与业务包优先级对应的候选资源集合；
选择频域资源最大的候选资源集合；
选择负载最低的候选资源集合；
选择经占用资源排除后、剩余资源最多的候选资源集合。
也就是说，当针对当前业务包确定的目标资源集合为多个时，UE可根据自身需求进行随机选择，也可以根据预先设定的选择方式进行选择，其中，需要说明的是，在本申请实施例中，对于从多个目标资源集合为当前业务包选择发送资源的方式并不进行限定。
实施例三：
由于在业务包发送的过程中，也会受到半双工的影响，因此为了因避免占用较多时隙而导致UE不能接收，应尽可能地在较为集中的时域上进行业务包的发送。然而当业务包较多，而UE上的PA数量有限时，必然涉及到PA共享的问题，由于在进行PA共享时，所选择的时隙长度可能不同，因此则会导致共享PA时造成相位不连续，从而影响系统性能。因此依据本申请的另一个方面，还提供了一种资源选择方法，以克服在业务包发送过程中，共享PA时造成相位不连续，而导致的系统性能显著下降的问题，如图5所示，所述方法包括以下步骤：
步骤S501：当多个业务包到达，UE针对每个业务包依次在对应的目标候选资源集合中,进行占用资源排除和/或功率排序。
针对每个业务包，UE会对从该业务包的目标候选资源集合进行占用资源排除和/或功率排序，然后选择出一定比例的候选资源，作为该业务包的可用候选资源集合。其中进行目标候选资源集合进行占用资源排除和/或功率排序过程为现有技术，故在本申请实施例中，不再赘述。
步骤S502：在进行占用资源排除和/或功率排序可用候选资源集合中，根据自身具有的功率放大器PA的数量，从可用候选资源集合中，进行第一时隙资源的排除，然后进行发送资源的选择。
也就是说，当多个业务包到达时，在发送资源选择时刻，UE在依次为业务包选择发送资源时，需优先考虑UE的能力，其中所谓UE的能力包括UE当前能够支持的发送的链路的数量，以及UE具有的PA个数。
假如UE具有2个PA，并且前能够支持的发送的链路的数量为3个，那么针对第一个业务包，UE可以从第一个业务包对应的目标候选资源集合中选 择1个时隙资源，其中由于UE具有2个PA，因此为了避免占用较多时隙而导致UE不能接收，所以在为第二个业务包选择发送资源时，应该从第二个业务包对应的目标候选资源集合中再选择1个与为第一个业务包选择的时隙资源对应的时域交叠的时隙。也就是如图6所示，在根据PA数量进行发送资源的选择时，假如UE在载波1上为第一个业务包选择发送资源，UE在载波2上为第二个业务包选择发送资源，如果载波1上的时隙1已经被选择，那么在从载波2上为第二个业务包选择发送资源时，则应该在与时隙1的时域上交叠的资源中进行选择，那么此时针对第二个业务包可选的时隙有时隙1和时隙2，由于每个PA对应时域上不同的起始点，因此UE为第二个业务包选择时隙2。
具体地，在本申请实施例中，当多个业务包到达，UE针对每个业务包依次在对应的目标候选资源集合中进行发送资源选择，依据以下至少一种顺序：
按照所有目标候选资源集合的参数集中时隙长度从小到大的顺序；
按照所有目标候选资源集合的参数集中，相同时隙长度数量从多到少的顺序；
按照网络侧配置或者预配置的目标候选资源集合的编号顺序；
按照网络侧配置或者预配置的目标候选资源集合的优先级顺序；
按照目标候选资源集合对应的业务包的优先级顺序；
按照高层通知的目标候选资源集合的资源选择顺序。
也就是说，UE在为每个业务包选择资源时，可以根据以上规定顺序中的至少一种为每个业务包选择目标候选资源集合，在本申请实施例中，并不进行具体限定。
具体地，在本申请实施例中，候选资源集合包括为以下至少一种：载波；资源池；部分带宽。候选资源集合的可以是载波、资源池、部分带宽其中的至少一种或者各种组合方式；例如，如果每个载波上仅配置一个资源池，该资源池覆盖整个载波上的全部频域资源，则候选资源集合可以以载波为粒度或者以资源池为粒度；如果每个载波上配置多个资源池，则确定的候选资源 集合以资源池为粒度；同理，如果每个载波上配置多个部分带宽，则确定的候选资源集合以部分带宽为粒度。资源池或者部分带宽相关的参数可通过网络侧配置或者预配置参数获得。
其中，由于UE在选择出可用的候选资源之后，会进一步在可用的候选资源中排除进行共享PA时导致PA相位不连续的时隙资源，也就是第一时隙资源。因此通过对超出PA数量的业务包进行PA共享时，可以保证为进行共享PA的业务包选择的发送资源均为PA相位的时隙资源，从而可以避免在业务包发送过程中，因共享PA时相位不连续而导致的系统性能显著下降的问题。
其中，本申请实施例提供的资源选择方法适用于同一频带内，NR V2X直通链路上多载波发送场景，以及NR V2X和LTE V2X共存的场景。可结合考虑UE能力，如UE是否具备多个PA、是否能够满足同时在不同载波上、不同时域起始点的时隙上进行业务发送，进行相应的资源分配处理，从而避免PA数量有限时、在时隙不一致的情况共享PA造成PA相位不连续，而导致系统性能显著下降。
实施例四：
由上述实施例可知，UE在选择出可用的候选资源之后，会进一步在可用的候选资源中排除进行共享PA时导致PA相位不连续的时隙资源，也就是对上述第一时隙资源进行排除，因此，在本申请实施例中，排除所述第一时隙资源包括：
对可用候选资源集合中的所有时隙进行遍历，同时满足以下条件的第一目标时隙为第一时隙资源：
所述第一目标时隙相同的时域上，UE在其他候选资源集合上同时有业务包进行发送；
其他候选资源集合上同时进行业务包发送的时隙，与所述第一时隙的起点和终点均不相同；
其他候选资源集合上同时进行业务包发送的时隙，起点或终点不相同的时隙数量已与UE具有的PA数量相等。
在第一种场景下，如图7a所示，载波1为LTE V2X直通链路载波，载波2、3为NR V2X直连链路载波；载波1的子载波间隔15KHz，对应的时隙长度为1ms；载波2的子载波间隔为30KHz，对应的时隙长度为0.5ms；载波3的子载波间隔为60KHz，对应的时隙长度为0.25ms；UE在载波3上为业务包选择发送资源；载波1的时隙1已被选择，载波2上的时隙2已被选择；UE支持的发送链路数量为3；UE的PA数量为2。
针对载波3上的所有时隙依次根据上述条件进行判断，由于与载波3上的时隙1相同的时域上，载波1上的时隙1上同时有业务包发送，且载波3上的时隙1的起点和终点与载波1上的时隙1的起点和终点均相同，则将载波3上的时隙1排除；由于与载波3上的时隙2相同的时域上，载波1上的时隙1上同时有业务包发送，且载波3上的时隙2的起点和终点与载波1上的时隙1的起点和终点均相同，则将载波3上的时隙1排除；由于与载波3上的时隙3相同的时域上，载波1上的时隙1上同时有业务包发送，载波2上的时隙2上也同时有业务包发送，且载波3上的时隙3的起点和终点与载波1上的时隙1的起点和终点均相同，则将载波3上的时隙3排除；由于与载波3上的时隙4相同的时域上，载波1上的时隙1上同时有业务包发送，载波2上的时隙2上也同时有业务包发送，且载波3上的时隙4的起点和终点与载波1上的时隙1的起点和终点均相同，则将载波3上的时隙4排除；而与载波3上的时隙5-12相同的时域上，其他候选资源集合上没有业务包进行发送，因此不排除载波3上的时隙5-12。因此，由于载波3上的时隙1、2、3、4与载波1上的时隙1、载波2上的时隙2，均存在起点或者终点不一致的情况，其UE仅具有2个PA；所以载波3上的时隙1、2、3、4为第一时隙资源，且上述时隙上的候选资源均被排除。
如图7b所示，载波1、2、3均为NR V2X直连链路载波；载波1的子载波间隔15KHz，对应的时隙长度为1ms；载波2的子载波间隔为30KHz，对应的时隙长度为0.5ms；载波3的子载波间隔为60KHz，对应的时隙长度为0.25ms；UE在载波3上为业务包选择发送资源；载波1的时隙1已被选择， 载波2上的时隙2已被选择；UE支持的发送链路数量为3；UE的PA数量为2。
针对载波3上的所有时隙依次根据上述条件进行判断，由于与载波3上的时隙1相同的时域上，载波1上的时隙1上同时有业务包发送，且载波3上的时隙1的起点和终点与载波1上的时隙1的起点和终点均相同，则将载波3上的时隙1排除；由于与载波3上的时隙2相同的时域上，载波1上的时隙1上同时有业务包发送，且载波3上的时隙2的起点和终点与载波1上的时隙1的起点和终点均相同，则将载波3上的时隙1排除；由于与载波3上的时隙3相同的时域上，载波1上的时隙1上同时有业务包发送，载波2上的时隙2上也同时有业务包发送，且载波3上的时隙3的起点和终点与载波1上的时隙1的起点和终点均相同，则将载波3上的时隙3排除；由于与载波3上的时隙4相同的时域上，载波1上的时隙1上同时有业务包发送，载波2上的时隙2上也同时有业务包发送，且载波3上的时隙4的起点和终点与载波1上的时隙1的起点和终点均相同，则将载波3上的时隙4排除；而与载波3上的时隙5-12相同的时域上，其他候选资源集合上没有业务包进行发送，因此不排除载波3上的时隙5-12。因此，由于载波3上的时隙1、2、3、4与载波1上的时隙1、载波2上的时隙2，均存在起点和终点不一致的情况，其UE仅具有2个PA；所以载波3上的时隙1、2、3、4为第一时隙资源，且上述时隙上的候选资源均被排除。
在第二种场景下，如图8a所示，载波1为LTE V2X直通链路载波，载波2、3为NR V2X直连链路载波；载波1的子载波间隔15KHz，对应的时隙长度为1ms；载波2的子载波间隔为30KHz，对应的时隙长度为0.5ms；载波3的子载波间隔为30KHz，对应的时隙长度为0.5ms；UE在载波3上为业务包选择发送资源；载波1的时隙1已被选择，载波2上的时隙2已被选择；UE支持的发送链路数量为3；UE的PA数量为2。
针对载波3上的所有时隙依次根据上述条件进行判断，由于与载波3上的时隙1相同的时域上，载波1上的时隙1上同时有业务包发送，且载波3 上的时隙1的起点和终点与载波1上的时隙1的起点和终点均相同，则将载波3上的时隙1排除；由于与载波3上的时隙2相同的时域上，载波1上的时隙1上同时有业务包发送，载波2上的时隙2上也同时有业务包发送，但由于载波3上的时隙2的起点和终点与载波2上的时隙2的起点和终点均相同，因此载波3上的时隙2不排除，而与载波3上的时隙3-6相同的时域上，其他候选资源集合上没有业务包进行发送，因此不排除载波3上的时隙3-6。因此，由于载波3上的时隙1与载波1上的时隙1、载波2上的时隙2，均存在起点和终点不一致的情况，由于UE仅具有2个PA，而载波1上的时隙1、载波2上的时隙2分别被选择，且载波1上的时隙1、载波2上的时隙2的终端相同；所以载波3上的时隙1确定为第一时隙资源，且将载波3上的时隙1上的候选资源均被排除。
如图8b所示，载波1、2、3为NR V2X直连链路载波；载波1的子载波间隔15KHz，对应的时隙长度为1ms；载波2的子载波间隔为30KHz，对应的时隙长度为0.5ms；载波3的子载波间隔为30KHz，对应的时隙长度为0.5ms；UE在载波3上为业务包选择发送资源；载波1的时隙1已被选择，载波2上的时隙2已被选择；UE支持的发送链路数量为3；UE的PA数量为2。
针对载波3上的所有时隙依次根据上述条件进行判断，由于与载波3上的时隙1相同的时域上，载波1上的时隙1上同时有业务包发送，且载波3上的时隙1的起点和终点与载波1上的时隙1的起点和终点均相同，则将载波3上的时隙1排除；由于与载波3上的时隙2相同的时域上，载波1上的时隙1上同时有业务包发送，载波2上的时隙2上也同时有业务包发送，但由于载波3上的时隙2的起点和终点与载波2上的时隙2的起点和终点均相同，因此载波3上的时隙2不排除，而与载波3上的时隙3-6相同的时域上，其他候选资源集合上没有业务包进行发送，因此不排除载波3上的时隙3-6。因此，由于载波3上的时隙1与载波1上的时隙1、载波2上的时隙2，均存在起点和终点不一致的情况，由于UE仅具有2个PA，而载波1上的时隙1、载波2上的时隙2分别被选择，且载波1上的时隙1、载波2上的时隙2的终 端相同；所以载波3上的时隙1确定为第一时隙资源，且将载波3上的时隙1上的候选资源均被排除。
其中，由上述可知，由于已经排除了进行共享PA时导致PA相位不连续的时隙资源，因此当对超出PA数量的业务包进行PA共享时，可以保证为进行共享PA的业务包不选择的导致PA相位不连续的时隙资源，从而可以避免在业务包发送过程中，因共享PA时相位不连续而导致的系统性能显著下降的问题。
实施例五：
由于在业务包发送的过程中，会受到半双工的影响，因此为了因避免占用较多时隙而导致UE不能接收，应尽可能地在较为集中的时域上进行业务包的发送，所以可优先在排除第一时隙资源的可用候选集合中选择发送资源，因此在上述实施例的基础上，所述在排除第一时隙资源的可用候选集合中选择发送资源包括：
确定可用候选集合中的第二时隙资源，在所述第二时隙资源上的可用候选资源中，优先选择发送资源；所述第二时隙资源为在为其他业务包选择的其他候选资源上同时有业务包进行发送的时隙资源。
其中，所述确定可用候选集合中的第二时隙资源包括：
在排除第一时隙资源后剩余的可用候选资源集合中，遍历所述剩余的可用候选资源中所有的时隙，满足以下条件的第二目标时隙为第二时隙资源：
所述第二目标时隙相同的时域上，UE在其他候选资源集合上同时有业务包进行发送。
如图9a所示，载波1为LTE V2X直通链路载波，载波2、3为NR V2X直连链路载波；载波1的子载波间隔15KHz，对应的时隙长度为1ms；载波2的子载波间隔为30KHz，对应的时隙长度为0.5ms；载波3的子载波间隔为60KHz，对应的时隙长度为0.25ms；UE在载波3上为业务包选择发送资源；载波1的时隙1已被选择，载波2上的时隙2已被选择；UE支持的发送链路数量为3；UE的PA数量为2，其中，载波3上的时隙1上的候选资源，因为 会造成PA相位不连续，已被排除。
那么针对载波3来说，排除第一时隙资源之后的可用资源即为时隙2-时隙6，其中由于只有载波3上的时隙2，在载波1上和载波2上存在同时发送的业务包，因此则将载波3上的时隙2确定为第二时隙资源，并在载波3上的时隙2上优先选择发送资源。
如图9b所示，载波1、2、3为NR V2X直连链路载波；载波1的子载波间隔15KHz，对应的时隙长度为1ms；载波2的子载波间隔为30KHz，对应的时隙长度为0.5ms；载波3的子载波间隔为60KHz，对应的时隙长度为0.25ms；UE在载波3上为业务包选择发送资源；载波1的时隙1已被选择，载波2上的时隙2已被选择；UE支持的发送链路数量为3；UE的PA数量为2，其中，载波3上的时隙1上的候选资源，因为会造成PA相位不连续，已被排除。
那么针对载波3来说，排除第一时隙资源之后的可用资源即为时隙2-时隙6，其中由于只有载波3上的时隙2，在载波1上和载波2上存在同时发送的业务包，因此则将载波3上的时隙2确定为第二时隙资源，并在载波3上的时隙2上优先选择发送资源。
其中，由于确定出的第二时隙资源为从排除第一时隙资源后剩余的可用候选资源集合中进行确定的，且第二时隙资源的时域上，其他候选资源集合上同时有业务包进行发送，因此则说明确定出的第二时隙资源必定与任一个其他候选资源集合上同时进行发送的业务包的时隙的起点和终点相同。因此当在第二时隙资源上进行业务包的发送时，也必定会与任一个其他候选资源集合上同时进行发送的业务包共享PA，从而可以保证为进行共享PA的业务包选择的发送资源均为PA相位的时隙资源，从而可以避免在业务包发送过程中，因共享PA时相位不连续而导致的系统性能显著下降的问题。
实施例六：
在根据PA数量确定相应数量的时隙，以及确定能够共享PA的时隙之后，还应考虑业务包的发送次数，因此，在上述实施例的基础上，在本申请实施例中，所述方法还包括：
如果优先选择的发送资源数量不足当前业务包的发送次数，在优先选择的发送资源以外、排除所述第一时隙资源后的剩余可用候选资源集合中，选择相差数量的发送资源。
具体地，所述在优先选择的发送资源以外、排除所述第一时隙资源后的剩余可用候选资源集合中，选择相差数量的发送资源包括：
确定第三时隙资源，在第三时隙资源上的可用候选资源中优先选择相差数量的发送资源；第三时隙资源为可用候选资源所在时隙资源中，排除第一时隙资源和第二时隙资源后，与UE当前进行发送的其他候选资源集合中任一候选资源集合具有相同参数集的时隙资源。
如图10a所示，载波1为LTE V2X直通链路载波，载波2、3为NR V2X直连链路载波；载波1的子载波间隔15KHz，对应的时隙长度为1ms；载波2的子载波间隔为30KHz，对应的时隙长度为0.5ms；载波3的子载波间隔为30KHz，对应的时隙长度为0.5ms；UE在载波3上为业务包选择发送资源；载波1的时隙1和时隙4已被选择，载波2上的时隙2和7已被选择；UE支持的发送链路数量为3；UE的PA数量为2；载波3上的时隙1和时隙8上的候选资源，因为会造成PA相位不连续，均被排除；载波3上的时隙2和时隙7上的可用候选资源为优先选择的资源；如果发送业务包的发送次数为3。
由于载波3上的时隙2和时隙7上的可用候选资源为优先选择的资源，而此时业务包的发送数量为3个，因此则需要在优先选择的发送资源以外、排除所述第一时隙资源后的剩余可用候选资源集合再选择一个时隙。
由于载波3与载波2具有相同的参数集，那么可以优先在载波3上在优先选择的发送资源以外、排除所述第一时隙资源后的剩余可用候选资源中选择1个候选资源，其中载波3上在优先选择的发送资源以外、排除所述第一时隙资源后的剩余可用候选资源集合为时隙3-6，因此UE可以在载波3上的时隙3-6中任意选取一个时隙。
如图10b所示，载波1、2、3为NR V2X直连链路载波；载波1的子载波间隔15KHz，对应的时隙长度为1ms；载波2的子载波间隔为30KHz，对 应的时隙长度为0.5ms；载波3的子载波间隔为30KHz，对应的时隙长度为0.5ms；UE在载波3上为业务包选择发送资源；载波1的时隙1和时隙4已被选择，载波2上的时隙2和7已被选择；UE支持的发送链路数量为3；UE的PA数量为2；载波3上的时隙1和时隙8上的候选资源，因为会造成PA相位不连续，均被排除；载波3上的时隙2和时隙7上的可用候选资源为优先选择的资源；如果发送业务包的发送次数为3。
由于载波3上的时隙2和时隙7上的可用候选资源为优先选择的资源，而此时业务包的发送数量为3个，因此则需要在优先选择的发送资源以外、排除所述第一时隙资源后的剩余可用候选资源集合再选择一个时隙。
由于载波3与载波2具有相同的参数集，那么可以优先在载波3上在优先选择的发送资源以外、排除所述第一时隙资源后的剩余可用候选资源中选择1个候选资源，其中载波3上在优先选择的发送资源以外、排除所述第一时隙资源后的剩余可用候选资源集合为时隙3-6，因此UE可以在载波3上的时隙3-6中任意选取一个时隙。
由于在本申请实施例中，将UE当前进行发送的其他候选资源集合中任一候选资源集合具有相同参数集的时隙资源作为第三时隙资源，因此可以保证在参数集较为集中的时隙资源上发送业务包，从而在进行多载波发送时，针对不同时隙长度时的情况，结合考虑UE能力进行资源排除，保证PA共享时PA相位不连续，避免造成功率波动，提升系统性能。
