或者，
在根据接收的第一指示信息，确定所述第一终端的当前资源池与所述第一指示信息所指示的目标资源池相同的情况下，不对所述第一终端的当前资源池进行切换。
上述中，若第一终端不包括所述第一指示信息所指示的目标资源池，即第一终端的资源池集合中不包括目标资源池的情况下，或者，所述第一终端的当前资源池与所述第一指示信息所指示的目标资源池相同，则第一终端不对当前资源池进行切换。
上述中，在所述将所述第一终端的当前资源池切换为目标资源池之后，所述方法还包括：
采用所述目标资源池中的目标资源进行数据传输。其中，所述目标资源为所述多个资源池中除如下资源之外的资源：
其他终端的预留资源中参考信号接收功率(Reference Signal Received Power，RSRP)大于预设阈值的资源。其他终端不包括第一终端。第一指示信息与其他终端的资源预留信息联合编码。
预留资源通过所述第一终端在所述多个资源池中进行联合检测和/或资源排除确定。
第一终端在多个资源池中进行检测时，可对各资源池进行独立的检测(sensing)、资源排除等，然后(为了可以一个SCI调度多个资源池的资源或 方便其他形式的跨资源池传输)跨资源池联合进行资源选择，和/或，选择资源以进行跨资源池的传输。
例如：第一终端在第一资源池中进行检测，获取第一检测结果；在第二资源池中进行检测，获取第二检测结果，依次对各个资源池进行检测，获得对应的检测结果。根据各个资源池的检测结果和资源排除结果，在多个资源池中进行资源选择。
可选的，为了检测到跨资源池预留资源的情况，进行跨资源池联合检测、联合资源排除、联合候选资源集建立、联合进行资源选择和/或选择资源进行跨资源池的传输。第一终端对多个资源池中进行联合检测，排除同资源池和/或跨资源池的预留资源，和/或，根据资源池的检测结果和资源排除结果，在多个资源池(可以选择多个资源池中的部分或者全部)中进行资源选择。
当受到功率限制，和/或多个资源池传输数量的能力限制，和/或跨资源池传输能力限制，和/或射频(Radio Frequency，RF)链相关限制，对在某个资源池上传输资源所在的子帧上其他部分或全部资源池上的候选资源进行排除。
若多个资源池包括不同资源池上的预留资源，可在SCI中携带预留资源所在的一个或者多个资源池的资源信息。
上述中，所述预留资源包括其他终端在所述多个资源池中跨资源池预留的资源。
上述中，所述目标资源为所述多个资源池中当前时域资源中的资源；或者，所述目标资源为所述多个资源池中时域资源相同或重叠的资源。
上述中，所述目标资源池包括所述多个资源池中的N个资源池；
所述采用所述目标资源池中的目标资源进行数据传输，包括：
采用一个SCI调度的所述N个资源池中的目标资源进行数据传输；
或者，
采用N个SCI分别调度的所述N个资源池中的目标资源进行数据传输；
N为大于1的整数。
采用一个SCI调度的所述N个资源池中的目标资源进行数据传输时，可采用一个SCI调度的所述N个资源池中的目标资源对同一业务数据传输。同样的，采用N个SCI分别调度的所述N个资源池中的目标资源进行数据传输， 也可采用N个SCI分别调度的所述N个资源池中的目标资源对同一业务数据进行传输。
为了一个资源池的SCI可以调度多个资源池的资源(如图3a所示的实施例)，选择多个资源池(可以选择多个资源池中的部分或者全部)上具有相同时域的资源，或者存在时间重叠的时域资源；
若在多个资源池中同时传输数据，可以一个SCI同时调度多个资源池的资源进行传输，也可以在SCI指明相关关系的情况下多个SCI各自调度一个资源池的资源进行传输(如图3b所示的实施例，多个资源池传输属于一个业务的数据/TB)：上述中，在通过一个SCI调度的所述N个资源池中的目标资源进行数据传输的情况下，所述N个资源池中的第二资源池的物理副链路共享信道(Pysical Sidelink Share Channel，PSSCH)对应的SCI携带第三指示信息，所述第三指示信息用于指示利用所述N个资源池进行跨资源池传输。所述N个资源池中除所述第二资源池之外的其他资源池用于传输PSSCH，或者，用于传输PSSCH和所述SCI。也就是说，一个资源池上的PSSCH对应的SCI携带第三指示信息，指示其同时调度的多个资源池，进行跨资源池传输，被调度的其他资源池上可以只传输PSSCH，或传输SCI与PSSCH。上述中，在通过N个SCI分别调度的所述N个资源池中的目标资源进行数据传输的情况下，所述N个资源池中的各第三资源池的PSSCH对应的SCI携带第四指示信息，所述第四指示信息用于指示所述第三资源池上的传输属于跨资源池传输。
上述中，每个资源池的PSSCH对应的SCI携带第四指示信息，指明多个资源池上的传输相关，即指示此资源池上的传输同属于当前跨资源池传输；
上述中，在采用所述N个资源池中的目标资源进行数据传输的情况下，调整所述N个资源池中第四资源池的发送功率。
其中，所述第四资源池根据如下方式确定：
根据所述N个资源池中一个或多个资源池发送的数据包的优先级确定；或者，由所述第一终端确定。
在第一终端受到功率限制，无法在多个资源池上同时满功率发送时，可根据优先级大小先调整优先级较低的数据包(packets)所在的资源池上的发 送功率，使得总发送功率满足功率限制条件。即，第四资源池可为N个资源池中发送的数据包的优先级最小的资源池，或者，第四资源池可为N个资源池中发送的数据包的优先级小于预设优先级阈值的资源池。
若N个资源池中多个资源池发送的数据包的优先级相同，由第一终端自己决定先调整哪个资源池上的发送功率，使得总发送功率满足功率限制条件。以下对上述过程进行举例说明。
若UE A(即第一终端)与UE B(即第二终端)进行通信，UE B希望UE A切换资源池，例如，切换到一个可以高数据率通信的资源池，或者检测到第一终端的当前资源池可用资源不足时，UE B向UE A发送第一指示信息，以指示UE A进行资源池切换，第一指示信息可以携带在DCI、SCI或高层信令中。
UE A接收到第一指示信息后，开启切换激活定时器；
UE A将切换的目的资源池的标识，切换激活定时器的时间，正式切换的时间和切换等待定时器时间中的一项或多项的携带在SCI内，发送给UE B；
UE A不再在切换激活定时器到时之后的符号或时隙内继续执行接收操作，直到切换等待定时器失效和/或高层信令指示切换操作完成；
UE A直到切换等待定时器失效，和/或收到UE B的反馈后,才继续执行发送操作。
UE B在接收到UE A关于资源池切换的SCI后，UE B继续与UE A通信直到切换激活定时器的时间结束。
在UE A通知的正式切换时间或一段时间(假如UE A没有通知切换时间信息，UE B自己决定切换时间)之后，按照SCI中的指示信息调整与UE A通信的资源池，在切换等待定时器的时间后或者一段时间后，继续执行与UE A有关的发送和/或接收操作。另外，UE B还可向UE A发送关于资源池切换的反馈，告知UE A其已切换资源池。
上述中，UE A在收到第一指示信息，在时间t后，执行切换，时间t为切换激活定时器的时长，时长与当前数据包的处理时长和/或RF链处理时间有关。
第一终端可基于省电目的进行资源池切换。若第一终端的当前资源池为 P1，若第一终端需要省电，P1可以是一个周期较长，但是资源较稀疏的资源池。当第一终端在业务到来需要大量资源进行数据传输时，可根据DCI/SCI/高层信令指示，将P1切换到另一个可用资源较多的资源池P2。若业务结束，第一终端不再需要大量资源，为了减轻能量的消耗，需要切换到一个省电的资源池，可再次进行资源池切换。第一终端可根据接收到的DCI/SCI/高层信令，进行资源池切换，或第一终端自己决定从一个资源池切换到另一个资源池(此种情况下，第一终端根据预配置确定目标资源池)。
如图3a所示，当第一终端在t1时刻收到第一指示信息，或自己决定切换资源池后，开启切换激活定时器。在切换激活定时器到时后，即t2时刻正式执行切换动作，停止收发数据，并开启一个切换等待定时器。在切换等待定时器后或者收到高层信令指示终端切换动作完成后，视为切换到了目的资源池，此时为时刻t3。第一终端开始在新的资源池(即目标资源池)上进行收发数据等操作。
图3b所示为一个PSCCH调度多个资源池进行跨资源池传输。第一终端使用三个资源池对同一业务数据进行传输。第一终端在其多个资源池中进行跨资源池联合检测(sensing)，检测是否存在同资源池以及跨资源池的资源预留信息，得到一个联合的检测结果，然后统一进行已占用的资源排除，并获得一个总的候选资源集。三个资源池联合进行资源选择，选取三个资源池上相同或存在重叠的时域资源。
如图3b所示，进行传输时，P2中的PSSCH对应的SCI携带了调度其他两个P1和P3中的资源进行跨资源池传输。P1和P3中传输资源上时域资源和/或一些必要的配置与P2中的保持一致，P1和P3上的传输可以不携带PSCCH，由P2上的PSCCH统一指示调度。
图3c所示为多个PSCCH各自调度各资源池进行跨资源池传输。第一终端使用三个资源池对同一业务数据进行传输。第一终端在多个资源池中进行独立的检测(sensing)：第一终端在第一资源池中进行检测，获取第一检测结果，在第二资源池中进行检测，获取第二检测结果以及在第三资源池中进行检测，获取第三检测结果等，然后进行独立的资源排除，建立各自的候选资源集(这里同样可以进行联合的检测(sensing)、资源排除以及候选资源集建 立)，最后(为了方便SCI指示多个资源池上的传输具有相关关系和/或同一业务数据和/或同一TB等)跨资源池联合进行资源选择。
进行传输时，不限制三个资源池选取相同或重叠的时频资源，因此每个pool上的传输都需要携带SCI信息，对本资源池上的传输相关的资源选择以及配置进行单独指示，例如调制和编码方案(Modulation and coding scheme，MCS)，解调参考信号(Demodulation Reference Signal，DMRS)配置等。时间上后传输的两个资源池上的传输携带的SCI会携带额外的指示信息指向最早的传输，以指示此两个资源池上的传输同样属于此次的跨资源池传输，上述中，并不限制必须是时间上的相关指示，也可以是其他域上或者相关关系的指示。
图3d所示为第一终端在配置了多个资源池传输时，可以进行跨资源池的资源预留。第一终端可以在P2资源不足或节省另一个资源池上控制信令开销等情况下，通过SCI指示跨资源池预留资源池P1上的资源。此时SCI需要携带跨资源池预留资源的目的资源池的资源信息，例如资源池标识。
图3b、图3c中，n可理解为触发资源选择的时刻。
本申请中的资源池切换方法，第一终端可在不同资源池之间进行切换，可以期望终端在不同时刻获取最优性能。另外，由于第一终端在某一时刻可在多个资源池中进行发送，可以提高第一终端的峰值速率。
请参见图4，图4是本申请实施例提供的一种资源池切换方法的流程图，该资源池切换方法由第二终端、控制节点或网络侧设备执行，包括：
