需要说明的是，本公开实施例中所称的传输，可以包括发送和/或接收，Sidelink资源可以为Sidelink频带。
下面结合附图对本公开所提供的侧链路Sidelink通信方法、装置及存储介质进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种Sidelink通信方法的流程图。
如图2所示，本公开实施例提供的一种Sidelink通信方法，该方法由第一终端执行，该方法可以包括但不限于如下步骤：
S21：接收网络侧设备或第二终端发送的配置指示信息。
其中，响应于该配置指示信息为网络侧设备发送的，网络侧设备可以通过系统消息或者RRC(Radio Resource Control，无线资源控制)重配消息向第一终端发送配置指示信息。响应于该配置指示信息为第二终端发送的，第二终端可以通过PC5(接口)-RRC消息向第一终端发送配置指示信息。
S22：根据配置指示信息，确定多个候选Sidelink资源中Sidelink传输使用的目标Sidelink资源。
针对相关技术中，终端与终端之间仅支持在一个特定的Sidelink资源(例如频带)上进行信息的发送和接收，如果支持在多个Sidelink资源上进行信息的发送和接收，对于不同的Sidelink业务，存在无法确定如何使用多个Sidelink资源的问题。
本公开实施例中，第一终端能够从网络侧设备或者第二终端处接收配置指示信息，并且根据配置指示信息从两个或两个以上的候选Sidelink资源中确定Sidelink传输使用的目标Sidelink资源。在一种可能的应用场景中，该方案能够确定不同的Sidelink业务进行Sidelink传输时使用的目标Sidelink资源，从而，能够保证不同的Sidelink业务执行，避免数据丢失。本公开实施例中所称的传输，可以包括发送和/或接收。
其中，多个候选Sidelink资源为第一终端支持的与第二终端进行Sidelink传输使用的多个Sidelink资源。
本公开实施例中，在第一终端接收网络侧设备的发送的配置信息的情况下，网络侧设备发送的配置指示信息可以指示第一终端与第二终端进行Sidelink传输使用的目标Sidelink资源，其中，网络侧设备可以根据接收到第二终端发送的关于目标Sidelink资源的信息，确定第一终端与第二终端进行Sidelink传输使用的目标Sidelink资源，进一步的发送至第一终端。从而，第一终端与第二终端可以在相同的目标Sidelink资源上进行Sidelink传输，一方面能够保证不同的Sidelink业务执行，避免数据丢失，另一方面第一终端或第二终端可以在目标Sidelink资源接收第二终端或第一终端发送的信息，能够节省电能，避免资源浪费。
或者，网络侧设备可以根据其他信息确定第一终端与第二终端进行Sidelink传输使用的目标Sidelink资源，例如，网络侧设备在第一终端上报的第一终端支持与第二终端进行Sidelink传输使用的多个Sidelink资源中指定其中一个或多个Sidelink资源作为目标Sidelink资源，第一终端在确定目标Sidelink资源之后，可以发送至第二终端，或者，网络侧设备还可以将指定的目标Sidelink资源发送至第二终端。从而，第一终端与第二终端可以在相同的目标Sidelink资源上进行Sidelink传输，一方面能够保证不同的Sidelink业务执行，避免数据丢失，另一方面第一终端或第二终端可以在目标Sidelink资源接收第二终端或第一终端发送的信息，能够节省电能，避免资源浪费。
本公开实施例中，在第一终端接收第二终端的发送的配置指示信息的情况下，第二终端可以从第二终端支持的与第一终端进行Sidelink传输使用的多个候选Sidelink资源中，任选其中的一个或多个候选Sidelink资源确定为与第一终端进行Sidelink传输的目标Sidelink资源，之后，发送包含该信息的配置指示信息至第一终端，第一终端接收到第二终端发送的配置指示信息后，可以确定第一终端支持的与第二终端进行Sidelink传输使用的多个候选Sidelink资源中的目标Sidelink资源。从而，第一终端与第二终端可以在相同的目标Sidelink资源上进行Sidelink传输，一方面能够保证不同的Sidelink业务执行，避免数据丢失，另一方面第一终端或第二终端可以在目标Sidelink资源接收第二终端或第一终端发送的信息，能够节省电能，避免资源浪费。
或者，第二终端可以根据其他方式，确定为与第一终端进行Sidelink传输的目标Sidelink资源，例如，第二终端接收网络侧设备的相关信息，从第二终端支持的与第一终端进行Sidelink传输使用的多个候选Sidelink资源中，确定目标Sidelink资源，或者，第二终端接收第一终端的相关信息，从第二终端支持的与第一终端进行Sidelink传输使用的多个候选Sidelink资源中，确定目标Sidelink资源，之后，发送包含目标Sidelink资源的配置指示信息至第一终端。从而，第一终端与第二终端可以在相同的目标Sidelink资源上进行Sidelink传输，一方面能够保证不同的Sidelink业务执行，避免数据丢失，另一方面第一终端或第二终端可以在目标Sidelink资源接收第二终端或第一终端发送的信息，能够节省电能， 避免资源浪费。
本公开实施例中，目标Sidelink资源可以为多个候选Sidelink资源中的一个或多个，可以理解的是，在目标Sidelink资源为多个候选Sidelink资源中的一个的情况下，第一终端与第二终端可以在确定的这一个候选Sidelink资源上进行Sidelink传输，能够保证不同的Sidelink业务执行，节省电能，避免资源浪费。而在目标Sidelink资源为多个候选Sidelink资源中的多个的情况下，在多个候选Sidelink资源上进行Sidelink传输，一个候选Sidelink资源上传输失败，还有其他候选Sidelink资源传输，能够保证Sidelink业务执行，避免数据丢失。
在一些实施例中，本公开实施例中提供的Sidelink通信方法，还包括：在目标Sidelink资源上与第二终端进行通信。其中，本公开实施例中所称的通信可以包括发送和/或接收，即：在目标Sidelink资源上向第二终端发送待执行Sidelink业务对应的Sidelink信息；或者，在目标Sidelink资源上接收第二终端发送的待执行Sidelink业务对应的Sidelink信息。
本公开实施例中，第一终端接收到网络侧设备或第二终端的配置指示信息，确定sidelink传输使用的目标Sidelink资源，进而在目标Sidelink资源上进行Sidelink传输，包括在目标Sidelink资源上向第二终端发送待执行Sidelink业务对应的Sidelink信息，或在目标Sidelink资源上接收第二终端发送的待执行Sidelink业务对应的Sidelink信息。从而能够保证第一终端的待执行Sidelink业务对应的Sidelink信息能够准确接收和发送，避免数据丢失，并且，在接收待执行Sidelink业务对应的Sidelink信息时，能够在确定的目标Sidelink资源上进行接收，第一终端不需要在多个Sidelink资源上接收，能够节省第一终端的电能，避免资源浪费。
请参见图3，图3是本公开实施例提供的另一种Sidelink通信方法的流程图。
如图3所示，本公开实施例提供的另一种Sidelink通信方法，该方法由第一终端执行，该方法可以包括但不限于如下步骤：
S31：接收网络侧设备发送的第一配置指示信息；其中，第一配置指示信息用于指示Sidelink业务属性与多个候选Sidelink资源之间的对应关系。
其中，第一配置指示信息指示Sidelink业务属性与多个候选Sidelink资源之间的对应关系，在存在多个Sidelink业务属性的情况下，可以指示不同Sidelink业务属性分别对应不同的Sidelink资源，或者还可以指示不同Sidelink业务属性对应相同的Sidelink资源；在存在一个Sidelink业务属性的情况下，可以指示Sidelink业务属性对应多个Sidelink资源中一个或多个。
其中，Sidelink资源可以为Sidelink频带。
本公开实施例中，网络侧设备可以通过系统消息或者RRC重配消息，向第一终端发送指示Sidelink业务属性与多个候选Sidelink资源之间的对应关系的第一配置指示信息，第一终端接收到系统消息或者RRC重配消息之后，能够根据第一配置指示信息确定Sidelink业务属性与多个候选Sidelink资源之间的对应关系。
在一些实施例中，Sidelink业务属性以下至少一个：
服务质量QoS；
sidelink目的地址；
