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。
