Description

一种传输时间处理方法及相关设备 技术领域
本申请涉及通信技术领域，尤其涉及一种传输时间处理方法及相关设备。
背景技术
目前，授权频段的使用已经不能够满足急剧增长的移动数据流量，因此，除了提高授权频段传输数据的能力外，还需要充分利用非授权频段。非授权频段是一种任何人都可以用来部署无线通信的频段，例如无线电话、蓝牙以及遥控器等都可以在满足监管要求的条件下使用该非授权频段来传输数据。
但是，终端在使用该非授权频段时，需要采用竞争的方式来获取该非授权频段的传输资源，如传输时间和频点等。然而，针对无线网状网络来说，中继节点需要进行两次竞争才能将父节点的数据传输给子节点，例如，中继节点首先需要竞争到资源，利用该资源获取子节点的数据；再次竞争到资源时，将获取的数据传输给父节点，这样，不利于提高信道利用率。
发明内容
本申请提供一种传输时间处理方法及相关设备，能够采用传输时间共享的方式使用信道资源，提高信道利用率。
第一方面，本申请提供一种传输时间处理方法，该方法中，第一设备确定配置给第二设备的传输时间单元，所述第二设备为所述第一设备的传输时间授予节点；所述第一设备根据所述配置给所述第二设备的传输时间单元，向所述第二设备发送传输时间授予消息；所述传输时间授予消息中包括单元指示消息，所述单元指示信息用于指示配置给所述第二设备的传输时间单元，所述配置给所述第二设备的传输时间单元用于传输所述第二设备与其子节点之间的数据。可见，本申请与现有技术中采用竞争方式获得传输时间的方法相比，可以使得第二设备直接使用分配的传输时间单元，避免竞争导致的信道利用率较低的问题。
在一种可能的实现方式中，第一设备接收第二设备发送的时间需求消息，所述时间需求消息用于请求所述第一设备为所述第二设备配置传输时间单元；所述第一设备确定配置给第二设备的传输时间单元，包括：所述第一设备根据所述时间需求消息确定配置给第二设备的传输时间单元。
本申请中，时间需求消息用于请求第二设备的传输时间单元，第二设备为第一设备的传输时间授予节点，也就是说，第一设备可以为第二设备授予传输时间，相应的，第一设备也可以称为传输时间共享节点，也就是说，第一设备可以将自身获取的传输时间共享给其他设备；也可以说，第一设备为第二设备的父节点；其中，第二设备的传输时间单元用于传输第二设备与第二设备的子节点之间的待传输数据。
另外，该传输时间授予消息中包括单元指示信息，该单元指示信息用于指示配置给第二设备的传输时间单元。其中，该传输时间授予消息可以以广播或单播的形式发送，当采用广播的形式发送时，各第二设备接收到的传输时间授予消息相同，但可以根据该传输时 间授予消息中的单元指示信息来识别出配置给自身的传输时间单元。
在一种可能的实现方式中，第一设备向所述第二设备发送上行调度信息，所述上行调度信息用于指示所述第二设备上行传输的时频资源；所述第一设备接收第二设备发送的时间需求消息，包括：所述第一设备接收所述第二设备在所述时频资源上发送的时间需求信息。例如，当第二设备接收到第一设备发送该上行调度信息后，第二设备可以在该上行调度信息指示的时频资源上发送时间需求消息，可以认为该上行调度信息为第二设备发送时间需求消息的触发消息，即该上行调度信息具有分配上行传输的时频资源以及触发第二设备发送时间需求消息的功能。
在一种可能的实现方式中，第一设备可以向第二设备发送触发配置消息，该触发配置消息中包括周期指示信息和/或事件指示信息，所述周期指示信息用于指示所述第二设备发送所述时间需求消息的时间周期；所述事件指示信息用于指示所述第二设备发送所述时间需求消息的触发事件，如第二设备待传输数据超过某个门限；相应的，所述时间需求消息是所述第二设备根据所述周期指示信息指示的时间周期和/或所述事件指示信息指示的触发事件发送的。这样，第二设备周期性的或者产生触发事件时向第一设备上报时间需求消息，可以使得第一设备清楚各第二设备的时间需求情况，从而及时为各第二设备分配传输时间单元。
在一种可能的实现方式中，第二设备可以根据周期指示信息指示的时间周期或者事件指示信息指示的时间与上行调度信息相结合来发送时间需求消息。例如，当周期指示信息指示的时间周期或者事件指示信息指示的事件未到或未出现时，第二设备只要接收到该上行调度信息，就可以向第一设备上报该时间需求消息。再例如，第二设备可以在周期指示信息指示的时间周期到达时或即将到达时，向第一设备发送上行调度信息请求消息来请求上行调度信息，以便于在该上行调度信息指示的时频资源上发送时间需求消息；相应的，第二设备也可以在事件指示信息指示的事件发生时，向第一设备发送上行调度信息请求消息来请求上行调度信息，以便于在该上行调度信息指示的时频资源上发送时间需求消息。本申请不做限定。
在一种可能的实现方式中，第一设备获取第一传输时长后，可以先确定第一设备与第二设备之间进行数据传输所需的第二传输时长，第一设备可以根据第一传输时长和第二传输时长来判断是否执行传输时间共享功能，若执行，则可以向第二设备发送触发消息，该触发消息可以触发第二设备发送时间需求消息，从而为第二设备分配传输时间单元。该实现方式在能够进行传输时间共享功能时，才触发第二设备发送时间需求消息，从而节省信令的开销。
在另一种可能的实现方式中,第一设备可以确定配置给第二设备的传输时间单元后,再获取第一传输时长,第一设备根据该第一传输时长和配置给第二设备的传输时间单元确定第一传输时长中分配给第二设备的传输时间单元,这样,第一设备向第二设备发送的传输时间授予消息中携带第一传输时长中分配给第二设备的传输时间单元。
其中，第一设备获取第一传输时长的方式可以为竞争获得，也可以由第一设备的父节点，如第一设备的传输时间共享节点共享的方式获得的。其中，第一设备确定第一设备与第二设备之间进行数据传输所需的第二传输时长可以为：第一设备根据与第二设备之间的 链路质量以及待传输数据量估算所需的第二传输时长。
其中，第一设备可以通过判断第一传输时长是否大于第二传输时长来确定是否执行传输时间共享功能。
在一种可能的实现方式中，所述配置给所述第二设备的传输时间单元为第一传输时长的子集，所述第一传输时长为所述第一设备获取的传输时长。例如，所述第一设备获取第一传输时长；所述第一设备根据所述时间需求消息确定配置给第二设备的传输时间单元，包括：所述第一设备根据所述第一传输时长和所述时间需求消息确定配置给第二设备的传输时间单元；所述配置给所述第二设备的传输时间单元为所述第一传输时长的子集。
在一种可能的实施方式中，所述第一传输时长至少包括第一传输时间单元和第二传输时间单元，所述第一传输时间单元用于由所述第一设备传输与所述第二设备之间的数据；所述配置给所述第二设备的传输时间单元为所述第二传输时间单元的子集。
例如，所述第一设备利用获取的第一传输时间单元传输与所述第二设备之间的待传输数据；所述第一设备根据所述时间需求消息确定别配置给第二设备的传输时间单元，包括：所述第一设备根据第二传输时间单元和所述时间需求消息确定分配给所述第二设备的传输时间单元。也就是说，第一设备接收到第二设备发送的时间需求消息之后，可以先利用获取的第一传输时间单元来传输自身所需传输的上下行数据，根据第二设备发送的时间需求消息将第二传输时间单元的部分或全部分配给第二设备，这样，避免第一设备采用传输时间共享功能所导致的自身所需传输的上下行数据无法传输的问题。
在一种可能的实现方式中，所述时间需求消息中包括所述第二设备所需的第三传输时长，所述第一设备根据所述时间需求消息确定分配给所述第二设备的传输时间单元，包括：所述第一设备根据所述第二设备所需的第三传输时长，将所述第二传输时间单元的全部或者部分配置给所述第二设备，获得配置给所述第二设备的传输时间单元。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
为了解决现有技术中非授权频段的信道利用率较低以及传输延迟大的问题，本发明实施例基于图1所示的无线网状网络提出了一种解决方案，用以提高非授权频段的信道利用率以及降低传输延迟。如图1所示，第一设备以基站NB0为例，至少一个第二设备以基站(Node Base,NB)1和NB2为例，第二设备的子节点以用户终端(User Equipment,UE)为例，如基站1的子节点分别为UE11和UE12，基站2的子节点为UE21。本发明实施例可以使得分别NB0分别为NB1和NB2分配传输时间单元，NB1可以基于分配的传输时间单元传输NB1与UE11、UE12之间的待传输数据，NB2可以基于分配的传输时间单元传输NB2与UE21之间的待传输数据。
也就是说，NB0可以称为传输时间共享节点，即可以将自身获取的传输时间共享给其他节点的设备；NB1和NB2可以称为传输时间授予节点，即能够从其父节点NBO处获得所分配的传输时间单元。
可选的，本发明实施例提供的无线网状网络可以包括至少一个第一设备和至少一个第二设备，其中，每个第一设备可以为至少一个第二设备分别提供传输时间单元，第二设备可以利用第一设备所提供的该传输时间单元来传输自身的上下行数据，其中，上下行数据为第二设备与第二设备的子节点之间进行上行或下行传输的数据。
本发明实施例中，传输时间单元为时域上的时间单元，可包含整数个符号，可以是指子帧，也可以是指时隙(slot)，还可是指无线帧、微时隙(mini slot或sub slot)、多个聚合的时隙、多个聚合的子帧、符号等等，还可以是指传输时间间隔(Transmission Time Interval， TTI)。其中，一种传输时间单元在时域内可包含整数个另一种传输时间单元，或者，一种传输时间单元在时域内的时长等于整数个另一种传输时间单元在时域内的时长，例如，一个微时隙/时隙/子帧/无线帧内包含整数个符号，一个时隙/子帧/无线帧内包含整数个微时隙，一个子帧/无线帧内包含整数个时隙，一个无线帧包含整数个子帧等，也可以存在其余包含举例，本发明实施例不做限定。
本发明实施例中第一设备和第二设备可以为相同的设备，也可以为不同的设备。第一设备为第二设备的父节点；或者，第一设备称为传输机会共享节点，第二设备称为传输机会授予节点，另外，若第二设备也有下级节点，则第二设备相对于其下级节点也可以称为传输机会共享节点；也就是说，第一设备相对于其下级节点，如至少一个第二设备，为父节点或传输机会共享节点；第一设备相对于其上级节点，为子节点或传输机会授予节点，即第一设备与至少一个第二设备之间上下行传输的时间可以由第一设备竞争获得，也可以如本发明实施例所述的传输时间分配方法，由上级节点授予。本发明实施例以第一设备为父节点或传输机会共享节点，至少一个第二设备为第一设备的子节点或传输机会授予节点，并且每个第二设备还有其下级节点，第二设备与其下级节点之间上下行传输所需的时间由第一设备分配为例进行阐述。其中，第二设备的下级节点可以为用户终端，也可以为传感器节点等。本发明实施例不做限定。
本发明实施例中，第一设备、第二设备或第二设备的下级节点可以为无线终端，该无线终端可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备，其可以经无线接入网(如RAN，radio access network)与一个或多个核心网进行通信。例如，该用户设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，如个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(Session InitiationProtocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal DigitalAssistant，PDA)等，它们与无线接入网交换语言和/或数据。可选的，该用户设备还可以称为移动台(Mobile Station，MS)、移动终端(mobile terminal)、订户单元(Subscriber Unit，SU)、订户站(Subscriber Station，SS)，移动站(Mobile Station，MB)、远程站(Remote Station，RS)、接入点(Access Point，AP)、远程终端(Remote Terminal，RT)、接入终端(Access Terminal，AT)、用户终端(User Terminal；UT)、用户代理(UserAgent，UA)、终端设备(User Device，UD)等，本申请不做限定。
本发明实施例中，第一设备、第二设备或第二设备的下级节点也可以为基站、发送接收点(TransmissionReceptionPoint，TRP)或者射频拉远单元(Radio Remote Unit，RRU)。基站可以是指接入网中在空中接口上通过一个或多个扇区与终端通信的设备，其可协调对空中接口的属性管理。例如，该基站可以是GSM或CDMA中的基站，如基站收发台(base transceiver station，BTS)，也可以是WCDMA中的基站，如NodeB，还可以是LTE中的演进型基站，如eNB或e-NodeB(evolutional Node B)，还可以是5G系统中的基站，或未来网络中的基站，等等，本申请不做限定。可选的，该基站还可以是中继设备，或者具备基站功能的其他网元设备。其中，第二设备的下级节点还可以为一些传感器节点等，本发明 实施例不做限定。
需要说明的是，图1中所包含的第一设备、第二设备的数量和类型仅仅是一种例举，本发明实施例并不限制于此。比如，还可以包括一个或多个与第一设备进行通信的第二设备，或者第二设备可以包括一个或多个与第二设备进行通信的用户终端，为简明描述，不在附图中一一描述。如图1所示，尽管图1示出了第一设备、第二设备为基站，第二设备的多个下级节点为用户终端，如手机，但本发明实施例所述的通信系统可以并不限于包括基站和手机，譬如还可以包括用于承载某些网络功能或数据处理功能的设备等，这些对于本领域普通技术人员而言是显而易见的，在此不一一详述。
由于在现有技术中，第一设备与第二设备之间的传输时间以及第二设备与其子节点之间的传输时间都是通过竞争获得的，导致子节点需要发送到网络侧的数据，需要经过两次竞争获得数据后才能达到网络侧的第一设备，因此，导致非授权频段的信道利用率较低以及延时较大。
本申请提供一种资源分配方法，使得第一设备可以根据第二设备与其子节点之间的时间需求情况将自身获得的非授权频段的传输时间分享给第二设备，以使第二设备与其子节点之间进行上下行数据的传输，从而，可以提高非授权频段的信道利用率以及缩短第二设备与其子节点之间的传输时延。
以下对本发明实施例进行详细阐述，其中，本发明实施例以一个第一设备与一个第二设备之间的交互为例进行阐述。
请参阅图2a，图2a是本发明实施例提供的一种传输时间处理方法的流程示意图，如图2a所示，该传输时间处理方法可以包括：
101、第一设备确定配置给第二设备的传输时间单元；
102、第一设备向第二设备发送传输时间授予消息，该传输时间授予消息中包括单元指示信息，该单元指示信息用于指示配置给第二设备的传输时间单元。
103、第二设备接收第一设备发送的传输时间授予消息，根据单元指示信息确定配置给自身的传输时间单元；
104、第二设备在配置给自身的传输时间单元上传输与其子节点之间的数据。
可见，本发明实施例针对非授权频段，可以通过传输时间共享节点，即第一设备，为传输时间授予节点，即第二设备，分配传输时间单元，与现有技术中采用竞争方式获得传输机会或传输时间相比，可以提高信道的利用率。
在另一种可能的实现方式中，如图2b所示，该传输时间处理方法中，步骤101之前，第一设备还可以接收第二设备发送的时间需求消息，该时间需求消息用于请求所述第一设备为所述第二设备配置传输时间单元。
也就是说，图2b所示的传输时间处理方法中，在步骤101之前，还可以包括：
105、第二设备向第一设备发送时间需求消息；
相应的，步骤101可以为：第一设备根据所述时间需求消息确定配置给第二设备的传输时间单元。
在另一种实现方式中，如图2b所示，步骤105中第二设备向第一设备发送时间需求消息之前，还可以包括：
106、第一设备向第二设备发送上行调度信息；
其中，该上行调度信息用于触发第二设备发送时间需求消息，另外，该上行调度信息用于指示所述第二设备上行传输的时频资源。相应的，步骤104中，第二设备向第一设备发送时间需求消息可以为：第二设备在上行调度信息指示的时频资源上发送时间需求消息；相应的，步骤106中，第一设备接收第二设备发送的时间需求消息，可以为：第一设备接收所述第二设备在所述时频资源上发送的时间需求信息。
其中，该时间需求消息用于请求第一设备为第二设备配置传输时间单元，所述第二设备为所述第一设备的传输时间授予节点，第二设备的传输时间单元用于传输第二设备与其子节点之间的待传输数据；该待传输数据包括第二设备要发送给子节点的下行数据以及子节点要发送给第二设备的上行数据。
在又一种可能的实现方式中，所述第一传输时长至少包括第一传输时间单元和第二传输时间单元，所述第一传输时间单元用于由所述第一设备传输与所述第二设备之间的数据；所述配置给所述第二设备的传输时间单元为所述第二传输时间单元的子集。例如，第一设备根据第一传输时间单元传输与第二设备之间的待传输数据；相应的，第一设备根据时间需求消息确定分配给第二设备的传输时间单元，包括：第一设备根据第二设备发送的时间需求消息，将所述第二传输时间单元的全部或者部分分配给第二设备。
在又一种可能的实现方式中，所述配置给所述第二设备的传输时间单元为第一传输时长的子集，所述第一传输时长为所述第一设备获取的传输时长。例如，第一设备根据所述时间需求消息确定配置给第二设备的传输时间单元之前，第一设备还需要获取第一传输时长，该第一传输时长可以为非授权频段或授权频段上的传输时间单元；第一设备根据时间需求消息确定配置给第二设备的传输时间单元，包括：所述第一设备根据所述第一传输时长和所述时间需求消息确定配置给第二设备的传输时间单元；所述配置给所述第二设备的传输时间单元为所述第一传输时长的子集。具体的，该第一传输时长除了一部分传输时间单元用于传输第一设备与第二设备之间的数据之外，还需要一部分来传输时间授予消息，这样，第一传输时长中除了这两部分外的剩余的传输时间单元可以配置给第二设备，由第二设备使用传输第二设备与其子节点之间的数据。例如，所述第一传输时长至少包括第一传输时间单元和第二传输时间单元，所述第一传输时间单元用于由所述第一设备传输与所述第二设备之间的数据；所述配置给所述第二设备的传输时间单元为所述第二传输时间单元的子集。其中，该数据可以包括用户面数据和控制面数据，用户面数据也可以称为业务数据，控制面数据一般指控制信令等。其中，时间需求消息中包括第二设备所需的第三传输时长，该第三传输时长是第二设备根据第二设备与其子节点之间的链路质量和所需传输的数据量确定的。
在另一种实施方式中，时间需求消息还可以包括第二设备所需传输的业务类型和/或业务优先级，相应的，第一设备根据所述第二设备所需的第三传输时长，确定配置给所述第二设备的传输时间单元，包括：所述第一设备根据所述第二设备所需的第三传输时长以及所述第二设备所需传输的业务类型和/或业务优先级，将所述第二传输时间单元的全部或者部分配置给所述第二设备，获得配置给所述第二设备的传输时间单元。其中，业务类型也可以称为数据类型，业务优先级也可以称为数据优先级。这样，针对多个第二设备，第一 设备可以根据业务类型和/或业务优先级来为第二设备分配传输时间单元，从而，改善用户的操作体验，如待传输数据为语音、视频业务或者业务优先级高的第二设备可以优先分配传输时间单元，或者尽可能的满足传输所需的传输时间单元。
请参阅图3，图3是本发明实施例提供的另一种传输时间处理方法的流程示意图，其中，图3所示的传输时间处理方法与图2b所示的传输时间处理方法不同之处在于，在101中第二设备向第一设备发送时间需求消息之前，还可以包括以下步骤:
201、第一设备向第二设备发送触发配置消息；
该触发配置消息中包括周期指示信息和/或事件指示信息，所述周期指示信息用于指示所述第二设备发送所述时间需求消息的时间周期；所述事件指示信息用于指示所述第二设备发送所述时间需求消息的触发事件。
相应的，105中第二设备向第一设备发送时间需求消息，包括：
第二设备接收该触发配置消息，根据周期指示信息指示的时间周期和/或事件指示信息指示的触发事件向第一设备发送时间需求消息。
相应的，101中第一设备确定配置给第二设备的传输时间单元，包括：
第一设备根据时间需求消息确定配置给第二设备的传输时间单元。
例如，触发事件为第二设备所需的第三传输时长大于某一阈值时，则第二设备可以向第一设备发送时间需求消息，以请求第一设备给该第二设备分配传输时间单元。其中，第三传输时长为第二设备与其子节点之间传输数据所需的时长；再例如，触发事件为第二设备与其子节点之间的待传输数据达到一定门限。
可见，本发明实施例中，第二设备可以根据时间周期和/或触发事件向第一设备发送时间需求消息，以便于第一设备可以及时了解第二设备的传输时间需求情况，从而及时为第二设备分配传输时间单元，来传输待传输的数据。
请参阅图4，图4是本发明实施例提供的又一种传输时间处理方法的流程示意图，其中，图4所示的传输时间处理方法与图2a所示的传输时间处理方法不同之处在于，101之前，图4所示的传输时间处理方法还可以包括以下步骤：
301、所述第一设备获取第一传输时长；
302、第一设备确定所述第一设备与所述第二设备之间进行数据传输所需的第二传输时长；
303、第一设备根据所述第一传输时长和所述第二传输时长，判断是否执行传输时间共享功能；若执行所述传输时间共享功能，则执行步骤304，否则结束本流程；
在另一种可能的实现方式中,第一设备可以确定配置给第二设备的传输时间单元后,再获取第一传输时长,第一设备根据该第一传输时长和配置给第二设备的传输时间单元确定第一传输时长中分配给第二设备的传输时间单元,这样,第一设备向第二设备发送的传输时间授予消息中携带第一传输时长中分配给第二设备的传输时间单元。
可选的，若不执行传输时间共享功能，则第一设备可以继续执行步骤301，获取第一传输时长，直至判断执行传输时间共享功能时为止。其中，第一设备根据第一传输时长和 第二传输时长，判断是否执行传输时间共享功能，具体为：第一设备判断第一传输时长是否大于第二传输时长，若大于，则执行传输时间共享功能，以便于根据未使用的剩余的传输时间单元确定分配给第二设备的传输时间单元。例如，第一传输时长至少包括第一传输时间单元和第二传输时间单元，所述第一传输时间单元用于由所述第一设备传输与所述第二设备之间的数据；所述配置给所述第二设备的传输时间单元为所述第二传输时间单元的子集。
304、第一设备向所述第二设备发送触发消息。
其中，所述触发消息用于触发所述第二设备发送所述时间需求消息；也就是说，101具体为：第二设备接收到该触发消息时，向第一设备发送时间需求消息。
可见，本发明实施例可以在第一设备能够进行传输时间共享时，才触发第二设备发送时间需求消息，从而节省第一设备与第二设备之间的信令开销。
可选的，图4所示的传输时间处理方法中，可以不执行304，而是直接执行101确定配置给第二设备的传输时间单元，也就是说，该实施方式可以不必第二设备上报时间需求消息就可以下发传输时间授予消息，也就是说，该实施方式可以在第一设备确定能够执行传输时间共享功能，就可以为第二设备配置共享的传输时间单元。故该实施方式中，101还执行图2a所示的101步骤，即第一设备确定配置给第二设备的传输时间单元。
本发明实施例中，图2a、图2b至图4所示的传输时间单元处理方法可以适应于图1所示的网状网络的第一设备和第二设备。另外，第一设备和第二设备所执行的相关操作可以应用到同一个设备中，即第一设备的上级父节点可以执行图2a、图2b至图4中第一设备的相关功能，第一设备执行图2a、图2b至图4中第二设备的相关功能；第二设备也可以执行图2a、图2b至图4中第一设备的相关功能，第二设备的下级节点也可以执行图2a、图2b至图4中第二设备的相关功能。这样，第一设备和第二设备可以同时具有本发明实施例中第一设备和第二设备的功能，在不同的场景中执行相应的操作。另外，图2a、图2b至图4中，第一设备获取的第一传输时长可以为第一设备通过竞争所获取的非授权频段的传输时长，也可以为第一设备通过第一设备的父节点执行传输时间共享功能而被授予的传输时间单元，本发明实施例不做限定；相应的，第二设备获取的第一设备授予的传输时间单元可以进一步采用本发明实施例所述的传输时间单元处理方法，将传输时间单元再次分配给其子节点，使得子节点利用该传输时间单元传输该子节点与其下一级子节点之间的数据传输，本发明实施例也不做限定。
请参阅图5，图5是本发明实施例提供的一种传输单元处理装置的结构示意图，其中，该传输单元处理装置可以设置在第一设备中，第二设备为第一设备的子节点，相应的，第一设备为第二设备的父节点。如图5所示，该传输单元处理装置可以包括以下单元：
接收单元501，用于接收第二设备发送的时间需求消息，所述时间需求消息用于请求第二设备的传输时间单元，所述第二设备为所述第一设备的传输时间授予节点，所述第二设备的传输时间单元用于传输所述第二设备与其子节点之间的待传输数据；
配置单元502，用于根据所述时间需求消息确定配置给所述第二设备的传输时间单元；
发送单元503，用于向所述第二设备发送传输时间授予消息，所述传输时间授予消息中包括单元指示信息，所述单元指示信息用于指示所述配置给所述第二设备的传输时间单元。
在另一种实施方式中，配置单元502，用于确定配置给第二设备的传输时间单元；发送单元503，用于根据配置给第二设备的传输时间单元，向第二设备发送传输时间授予消息。也就是说，该实施方式中可以不包括接收单元501，即无论是否接收到时间需求消息，第一设备都可以根据自身的状况为第二设备共享传输时间单元。
在又一种实施方式中，发送单元503可以向第二设备发送上行调度信息，该上行调度信息用于指示第二设备上行传输的时频资源；接收单元501接收第二设备的时间需求消息可以具体为：接收单元501接收第二设备在该时频资源上发送的时间需求消息。
在一种可能的实施方式中，所述发送单元503，还用于向所述第二设备发送触发配置消息，所述触发配置消息中包括周期指示信息和/或事件指示信息，所述周期指示信息用于指示所述第二设备发送所述时间需求消息的时间周期；所述事件指示信息用于指示所述第二设备发送所述时间需求消息的触发事件；所述时间需求消息是所述第二设备根据所述周期指示信息指示的时间周期和/或所述事件指示信息指示的触发事件发送的。
在一种可能的实施方式中，所述设备还包括获取单元504和确定单元505，其中：
获取单元504，用于获取第一传输时长；
确定单元505，用于确定所述第一设备与所述第二设备之间进行数据传输所需的第二传输时长；

在另一种可能的实施方式中，所述配置给所述第二设备的传输时间单元为第一传输时长的子集，所述第一传输时长为所述第一设备获取的传输时长。例如，获取单元504获取第一传输时长后，配置单元502可以根据时间需求消息确定配置给第二设备的传输时间单元，具体为：根据第一传输时长和时间需求消息确定配置给第二设备的传输时间单元，其中，该配置给第二设备的传输时间单元为第一传输时长的子集。其中，发送单元503在发送传输时间授予消息时也可以占用该第一传输时长中的一部分传输时间单元。

在一种可能的实施方式中，所述时间需求消息中包括所述第二设备所需的第三传输时长，确定单元505根据所述时间需求消息确定分配给所述第二设备的传输时间单元，具体 为：根据所述第二设备所需的第三传输时长，将所述第二传输时间单元的全部或者部分配置给所述第二设备，获得配置给所述第二设备的传输时间单元。

确定单元603，用于根据所述单元指示信息确定配置给自身的传输时间单元，并在所述配置给自身的传输时间单元上传输与其子节点之间的待传输数据。
在另一种可能的实施方式中，该传输时间处理装置可以不包括发送单元601，即设置有该传输时间处理装置的第二设备可以在不发送时间需求消息时，就可以获得第一设备发送的传输时间授予消息。也就是说，第一设备可以根据自身的状态，如是否有多余的传输时间单元或要发送给第二设备的子节点的数据量等，来确定是否发送传输时间授予消息。也就是说，时间需求消息不是第一设备发送传输时间授予消息的唯一触发条件。
在又一种可能的实施方式中，接收单元602可以接收第一设备发送的上行调度信息；发送单元可以在该上行调度信息指示的时频资源上发送时间需求消息，进而由第一设备发送传输单元授予消息。也就是说，上行调度信息可以用于触发第二设备发送时间需求消息。
在一种可能的实现方式中，接收单元602，还用于接收所述第一设备发送的触发配置消息，所述触发配置消息中包括周期指示信息和/或事件指示信息，所述周期指示信息用于指示所述第二设备发送所述时间需求消息的时间周期；所述事件指示信息用于指示所述第二设备发送所述时间需求消息的触发事件；相应的，发送单元601向第一设备发送时间需求消息，具体为：根据所述周期指示信息指示的时间周期和/或所述事件指示信息指示的触发事件向第一设备发送所述时间需求消息。
在一种可能的实施方式中，接收单元602，还用于接收所述第一设备发送的触发消息，所述触发消息用于触发所述第二设备发送所述时间需求消息；相应的，发送单元601向第 一设备发送时间需求消息，具体为：在接收到所述触发消息时，向第一设备发送所述时间需求消息。
其中，所述时间需求消息中包括所述第二设备所需的第三传输时长；也就是说，发送单元601向第一设备发送时间需求之前，确定单元603还需要确定第二设备所需的第三传输时长，即第二设备与其子节点之间传输数据所需的时长。其中，第三传输时长是根据所述第二设备与其子节点之间的链路质量和所需传输的数据量确定的。
可选的，所述时间需求消息中还包括所述第二设备所需传输的业务类型和/或业务优先级。
