210,第一节点设备根据配置信息,在第一时域资源上接收第二节点设备发送的第一消息,以及在第二时域资源上向第三节点设备发送第二消息,其中,该配置信息指示该第一时域资源和/或该第二时域资源,该第二节点设备为该第一节点设备的父节点,该第三节点设备为该第一节点设备的子节点。
具体地,该第一消息可以是下行数据,也可以是寻呼消息,也可以是系统消息,也可以是下行参考信号,还可以是一些控制信令消息,本申请实施例对此不作限定。
具体地,该第二消息可以是下行数据,也可以是寻呼消息,也可以是系统消息,也可以是下行参考信号,还可以是一些控制信令消息,本申请实施例对此不作限定。
第一节点设备可以同时在第一时域资源上接收第二节点设备发送的第一消息,以及在第二时域资源上向第三节点设备发送第二消息。
该第一时域资源和/或该第二时域资源为下行时域资源。

可选地,该第一时域资源与该第二时域资源互不重叠。
可选地,该第二时域资源为第三时域资源的部分或者全部,其中,该第三时域资源为除该第一时域资源之外的下行时域资源。
例如,如图3所示,第一时域资源与第二时域资源互不重叠,第二时域资源为第三时域资源的部分,第一时域资源与第三时域资源构成所有的下行时域资源。
因此,第一时域资源可以与第二时域资源互不重叠,从而,第一节点设备可以同时在第一时域资源上接收其父节点设备发送的消息,以及在第二时域资源向其子节点设备发送消息。
可选地,该第一时域资源与该第二时域资源部分或者全部重叠。
例如,如图4所示,该第一时域资源与该第二时域资源部分重叠。
具体地,在该第一时域资源与该第二时域资源部分或者全部重叠时,该第一节点设备优先在该第一时域资源上接收该第二节点设备发送的该第一消息。
因此,第一时域资源可以与第二时域资源部分或者全部重叠,此时,第一节点设备优先在第一时域资源上接收其父节点设备发送的消息,从而,第一节点设备可以优先调度资源进行消息接收。
可选地,该第一节点设备在该第一时域资源上接收该第二节点设备发送的该第一消息的同时,该第三节点设备可以处于接收状态,例如,该第三节点设备接收除该第一节点设备之外的父节点发送的消息。
具体地,在该第一时域资源与该第二时域资源部分或者全部重叠时,该第一节点设备优先在该第二时域资源中与该第一时域资源的非重叠区域向第三节点设备发送该第二消息。
因此,第一时域资源可以与第二时域资源部分或者全部重叠,此时,第一节点设备优先在第二时域资源中与第一时域资源的非重叠区域向其子节点设备发送消息,从而,第一节点设备可以优先调度非重叠区域的下行时域资源进行消息发送。
可选地,若该DRX配置信息指示不需要在该第一时域资源上接收该第二节点设备发送的该第一消息时,该第一节点设备在该第二时域资源上向该第三节点设备发送该第二消息。
可选地,在该第一时域资源与该第二时域资源部分或者全部重叠时,该配置信息包括第一配置信息和第二配置信息,该第一配置信息指示该第一时域资源,该第二配置信息指示该第二时域资源。
可选地,该第一时域资源与该第二时域资源部分或者全部重叠,若该第一消息和/或该第二消息为下行参考信号或者系统消息,该第一节点设备在该第一时域资源中与该第二时域资源的非重叠区域接收该第二节点设备发送 的该第一消息,和/或,在该第二时域资源中与该第一时域资源的非重叠区域向第三节点设备发送该第二消息。
因此,第一节点设备在第一时域资源中与第二时域资源的非重叠区域接收其父节点设备发送的下行参考信号或者系统消息,以及在第二时域资源中与第一时域资源的非重叠区域向其子节点设备发送下行参考信号或者系统消息,从而,可以保证下行参考信号或者系统消息的可靠传输。
可选地,该第一节点设备向该第三节点设备发送该第一时域资源,和/或,该第二时域资源,和/或,该第一时域资源与该第二时域资源的重叠区域,和/或,该第一时域资源与该第二时域资源的非重叠区域。
若该第一节点设备向该第三节点设备发送该第一时域资源,该第三节点设备在除该第一时域资源之外的时域资源上接收该第一节点设备发送的消息。
若该第一节点设备向该第三节点设备发送该第一时域资源,和/或,该第二时域资源,该第三节点设备在该第二时域资源上接收该第一节点设备发送的消息。
若该第一节点设备向该第三节点设备发送该第一时域资源,和/或,该第二时域资源,和/或,该第一时域资源与该第二时域资源的重叠区域,该第三节点设备优先在第三时域资源上接收该第一节点设备发送的消息,其中,该第三时域资源为该第二时域资源中除该第一时域资源与该第二时域资源的重叠区域之外的时域资源。
若该第一节点设备向该第三节点设备发送该第一时域资源,和/或,该第二时域资源,和/或,该第一时域资源与该第二时域资源的重叠区域,和/或,该第一时域资源与该第二时域资源的非重叠区域,该第三节点设备优先在该第二时域资源中与该第一时域资源的非重叠区域上接收该第一节点设备发送的消息。
因此,第一节点设备向其子节点设备发送时域资源,从而,其子节点设备可以确定接收第一节点设备发送的消息的时域资源,进而,保证可靠传输。
可选地,该第一节点设备根据配置信息和DRX配置信息,在该第一时域资源上接收该第二节点设备发送的该第一消息,以及在该第二时域资源上向该第三节点设备发送该第二消息。
该第一节点设备在除该第一时域资源之外的下行时域资源上忽略指示该第一节点设备接收该第一消息的该DRX配置信息,以及拒绝接收该第一消息。
该DRX配置信息指示该第一节点设备在非激活定时器(inativitytimer)运行时间内或者连续定时器(ondurationtimer)运行时间内接收消息,以及在非激活定时器超时后或者连续定时器超时后拒绝接收消息。
具体地,若该第一节点设备根据该DRX配置信息确定在该第一时域资源上需要接收该第二节点设备的该第一消息,且该配置信息指示无针对该第一消息的时域资源时,该第一节点设备拒绝接收该第一消息。
可选地,该配置信息的优先级大于该DRX配置信息。
因此,第一节点设备在接收消息时,优先考虑配置信息所指示的时域资源,其次考虑DRX配置信息,从而,在配置信息与DRX配置信息发生冲突时,可以解决冲突。
可选地,该第一节点设备接收第四节点设备发送的该配置信息,该第四节点设备为该第二节点设备,或者,锚定节点设备,或者,接入网设备,或者,核心网设备。
可选地,该第一节点设备接收该第四节点设备通过RRC,或者,MAC CE,或者,DCI发送的该配置信息。
可选地,该方法200还包括:
该第一节点设备在第五时域资源上与第五节点设备进行D2D通信,其中,该第五时域资源为第六节点设备配置的,该第六节点设备为该第二节点设备,或者,锚定节点设备,或者,接入网设备,或者,核心网设备。
第一节点设备与第五节点设备为同一优先级的节点设备。
可选地,该第五时域资源可以是侧行时域资源。
因此,在本申请实施例的中继网络双工协调的方法中,第一节点设备可以根据动态配置信息,在第一时域资源上接收其父节点设备发送的消息,以及在第二时域资源向其子节点设备发送消息,从而,可以满足5G NR对backhaul link通信的需求。
