可选地，本申请实施例中，根据所述预留资源，选择第一资源，包括：
根据N个第一发送波束或第一发送面板对应的监听结果，选择X个第一资源，X为正整数，且X小于或者等于N，N为正整数，每个所述第一资源对应至少一个监听结果。
本申请实施例中，如果发送终端和接收终端之间存在N个(潜在使用)的第一发送波束或第一发送面板，当发送终端为某一个传输块(Transport Block，TB)选择资源时，发送终端为N个第一发送波束或第一发送面板选择X个资源。
其中，X的值是协议约定的或者是或是预先配置的或者是终端确定的。
进一步地，根据N个第一发送波束或第一发送面板对应的监听结果，选择X个第一资源，包括：
根据每个所述第一发送波束或第一发送面板对应的监听结果，确定一个第一资源；
根据由N个所述第一发送波束或第一发送面板对应的监听结果确定的第一资源，确定所述X个第一资源。
这里，针对每个第一发送波束或第一发送面板对应监听结果，独立确定 一个第一资源，另，由于根据N个监听结果独立确定的N个第一资源中存在重叠的资源，所以X小于或者等于N。
另外，本申请实施例中，发送终端也可以结合多个第一发送波束或第一发送面板对应的监听结果，来确定一个第一资源，例如，有5个第一发送波束或第一发送面板，该5个第一发送波束或第一发送面板对应5个监听结果，发送终端针对其中的监听结果1和监听结果2确定一个第一资源，并针对其中的监听结果3和监听结果4确定一个第一资源，针对其中的监听结果5确定一个第一资源，最终确定三个第一资源。
在本申请的一具体实施例中，X的值为1，即针对某TB的一次传输，发送终端为根据N个第一发送波束或第一发送面板的监听结果，选择一个第一资源，以减少资源占用量。
可选地，根据所述预留资源，选择第一资源，包括：
根据所述监听结果和目标发送资源，选择用于发送目标传输块的第一资源；
其中，所述目标发送资源包括第一发送资源和第二发送资源中的至少一项；
所述第一发送资源为用于发送第一传输块的资源，所述第一传输块为所述第二目标发送波束或第二目标发送面板对应的传输块中除所述目标传输块之外的传输块，所述第二目标发送波束或第二目标发送面板为所述目标传输块对应的发送波束或发送面板；
所述第二发送资源为用于发送第二传输块的资源，所述第二传输块为第三目标发送波束或第三目标发送面板对应的传输块中除所述目标传输块之外的传输块，所述第三目标发送波束为所述发送终端对应的发送波束中除所述第二目标发送波束之外的发送波束，所述第三目标发送面板为所述发送终端对应的发送面板中除所述第二发送面板之外的发送面板。
本申请实施例中，如果接收终端和发送终端之间存在一个或多个(潜在可用)的第一接收波束或第一接收面板，当接收终端为多个传输块选择接收资源时，针对某一个TB的接收，发送终端为该TB对应的L个第一发送波束或第一发送面板选择对应的资源时，发送终端排除所述L个第一发送波束或 第一发送面板为其他TB选择的时频资源，和/或，排除除所述L个第一发送波束或第一发送面板之外的其他第一发送波束和其他第一发送面板为其他TB选择的时频资源。
进一步地，本申请实施例的方法，还包括：
确定所述第三目标发送波束(第三目标发送面板)与所述第二目标发送波束(第二目标发送面板)是否能够进行空分复用，在不能进行空分复用的情况下，执行根据所述监听结果和目标发送资源，选择用于发送目标传输块的第一资源的操作。
需要说明的是，上述资源排除可以发生在识别备选资源集合之前，或者，发生在从备选资源集合选择传输资源时，这样，可以减少多个TB传输间的干扰。关于备选资源集合先进行如下说明。
相关技术中NR SL资源分配方式有两种，一种基于基站调度(模式(mode)1)，另一种基于UE自主资源选择(mode 2)，对于mode 2，具体的工作方式如下：1)TX UE在资源选择被触发后，首先确定资源选择窗口，资源选择窗口的下边界在资源选择触发后的T1时间，资源选择的上边界在触发后的T2时间，其中T2是UE实现的方式在其TB传输的分组时延预算(Packet Delay Budget，PDB)内选择的值，T2不早于T1。2)UE在资源选择的之前，需要确定资源选择的备选资源结合(candidate resource set)，根据资源选择窗口内的资源上测量的参考信号接收功率(Reference Signal Received Power，RSRP)与相应的RSRP阈值(threshold)做对比，如果RSRP高于RSRP threhold，那么对该资源进行资源排除，不能纳入备选资源集合。进行资源排除后资源选择窗口内剩余的资源组成备选资源集合。备选资源集合中的资源在资源选择窗口中的资源的占比要不少于x％，如果少于x％，RSRP threshold需要按照步进值(3dB)进行增加，再进行所述资源排除操作，直到可以选出不少于所述x％的资源。备选资源集合确定后，UE随机在备选资源集合中选择传输资源。另外，UE在本次传输可以为接下来的传输预留传输资源。
可选地，在资源选择集合中排除目标预留资源，得到剩余资源，包括：
方式1：在资源选择集合中排除目标预留接收资源，得到第一资源集合；在资源选择集合中排除目标预留发送资源，得到第二资源集合，根据所述第 一资源集合和所述第二资源集合，得到所述剩余资源；
或者，方式2：在资源选择集合中同时排除所述目标预留接收资源和目标预留发送资源，得到所述剩余资源；
或者，方式3：在资源集合中排除目标预留接收资源，得到第一资源集合，在所述第一资源集合中排除所述目标预留发送资源，得到所述剩余资源；
或者，方式4：在资源集合中排除所述目标预留发送资源，得到第二资源集合，在所述第二资源集合中排除所述目标预留接收资源，得到所述剩余资源。
本申请实施例中，对于上述方式1，可基于上述第一资源集合和第二资源集合的合集或并集，来得到上述剩余资源。
对于上述方式2：同时执行目标预留发送资源和目标预留接收资源的资源排除，得到剩余资源，并从剩余资源中选择第一资源。例如，根据目标预留资源(目标预留发送资源和目标预留接收资源)关联的RSRP测量和目标预留资源上传输信息的优先级指示进行资源排除。具体的，当目标预留资源关联的RSRP测量值大于预设RSRP测量阈值(RSRP测量阈值与优先级相关)时，排除该目标预留资源。目标预留接收资源和目标预留发送资源对应的RSRP测量阈值相同或存在预设差值，这里，RSRP测量阈值存在预设差值能够控制优先排除目标预留发送资源或目标预留接收资源。
本申请实施例的资源选择方法，发送终端基于目标终端的预留接收资源，或者，基于目标终端的预留接收资源和预留发送资源进行资源选择，能够有效降低接收终端的接收干扰，避免出现隐藏终端的问题，进而能够有效保证传输的可靠性。
