中继设备接收到发送侧UE发送的数据后再请求资源对该数据进行转发会存在时延较大的问题。为了克服该问题，NR R16引入提前缓存状态报告(pre-emptive bufferstatus report，pre-emptive BSR)机制解决该问题，即，用户设备可以发送pre-emptive BSR来指示待传输数据的数据量，用以提前请求传输资源，从而减小中继转发时延。但是，在V2X通信架构中，UE不能通过PC5通信接口向中继UE(具有中继功能的UE)指示待传输数据的数据量，故中继UE无法提前获取传输资源用以传输待传输数据。并且，中继UE通过pre-emptive BSR获取到的传输资源为Uu传输资源，但在UE与UE之间的侧行链路通信场景中，中继UE仅能通过侧行链路传输资源对UE的待传输资源进行转发。
可见，在侧行链路通信场景中，中继转发时延较大的问题仍然存在，而如何在侧行链路的通信场景中减小中继转发时延，是一个亟待解决的问题。
发明内容
本申请提供了一种资源调度方法、通信装置及系统，有利于实现中继设备基于待接收的数据量信息预先获取传输资源，从而在侧行链路的通信场景中减小中继转发时延。
第一方面，本申请提供一种资源调度方法，该方法可以应用于第一终端设备，也可以应用于第一终端设备的部件(芯片、处理器等)，以该方法应用于第一终端设备为示例，该方法包括：第一终端设备向第二设备发送指示信息，其中，该指示信息包括侧行链路的待传输数据的数据量信息，该待传输数据的数据量信息用于第二设备获取目标资源，该目标资源用于第二设备向第三通信设备转发该第二设备从侧行链路接收到的数据。其中，第一终端设备与第二设备之间存在侧行链路，第二设备与第三通信设备之间存在连接。
基于第一方面所描述的方法，第一终端设备向第二设备发送指示信息，第二设备可以根据该指示信息中包括的侧行链路的待传输数据的数据量信息提前获取传输该待传输数据的目标资源，可以减小第二设备对第一终端设备发送的待传输数据的转发时延。
在一种可能的实现中，第一终端设备向第二设备发送指示信息之前，第一终端设备还可以接收第一配置消息，并根据该第一配置消息确定向第二设备发送的指示信息。通过实施该可能的实现方式，第一终端设备在获取该第一配置消息之后，就可以根据该第一配置消息配置(或激活)自身发送指示信息的功能，进而使得第二设备根据该指示信息中的待传输数据的数据量信息提前获取目标资源。
在一种可能的实现中，第一配置消息包括逻辑信道LCH和逻辑信道组LCG之间的对应关系、LCH标识、承载标识、LCG标识、数据量门限和定时器时长中的一种或多种。通过实施该可能的实现方式，第一终端设备在接收该第一配置消息之后，可根据第一配置消息中的具体内容配置(或激活)自身发送指示信息的功能，并确定该指示信息包括的内容，进而使得第二设备根据该指示信息中的具体内容较精确地提前获取目标资源。
在一种可能的实现中，第一终端设备接收第一配置消息，具体的实现方式为：第一终端设备接收第三通信设备发送的第一配置消息。通过实施该可能的实现方式，第三通信设备是网络设备，第一终端设备处于第三通信设备的网络覆盖范围时，第三通信设备可以直接向第一终端设备发送第一配置消息，提高第一终端设备的配置效率。
在一种可能的实现中，第一终端设备接收第一配置消息之后，第一终端设备还可以根据该第一配置消息确定第二配置消息，并向第二设备发送该第二配置消息，其中，该第二配置消息包括LCH和LCG之间的对应关系、LCH标识、承载标识、LCG标识、数据量门限和定时器时长中的一种或多种。通过实施该可能的实现方式，可以保证第一终端设备和第二设备对该指示信息的内容达成共识，保持对指示信息功能认知的一致性。
在一个可能的实现中，第一终端设备接收第一配置消息，具体的实现方式为：第一终端设备接收第二设备发送的第一配置消息。通过实施该可能的实现方式，在第三通信设备是网络设备，第一终端设备不处于第三通信设备的网络覆盖范围时，可以由第二设备向第一终端设备转发该第一配置消息，以保证第一终端设备依然可以根据该第一配置消息配置(或激活)自身发送指示信息的功能。或，第三通信设备无法向第一终端设备发送第一配置消息时，第二设备可以向第一终端设备发送第一配置消息，以保证第一终端设备可以根据该第一配置消息配置(或激活)自身发送指示信息的功能。或，第三通信设备为远端设备时，第一终端设备接收的第一配置消息来源于第二设备，即，第一配置消息可以由第二设备根据侧行链路逻辑信道之间的映射关系来确定，以此保证第一终端设备可以根据该第一配置消息配置(或激活)自身通过侧行链路的PC5通信接口向中继设备发送指示信息的功能。
在一个可能的实现中，第一终端设备接收第二设备发送的第一配置消息之前，第一终端设备还可以向第二设备发送LCH之间的映射关系和/或LCH的服务质量信息，其中，该LCH之间的映射关系和/或LCH的服务质量信息用于第二设备确定第一配置消息。通过该可能的实现方式，可以使第三通信设备无法向第一终端设备发送第一配置消息时，第二设备可以根据第一终端设备发送的LCH之间的映射关系和/或LCH的服务质量信息确定第一配置消息，从而，第一终端设备可以根据该第一配置消息配置(或激活)自身发送指示信息的功能，同时，也使得第二设备和第一终端设备对该指示信息的内容达成共识，保持对指示信息功能认知的一致性。
在一个可能的实现中，第一终端设备根据第一配置消息确定向第二设备发送指示信息的具体实现方式为：第一终端设备确定满足触发条件，该触发条件与LCH标识、LCG标 识、承载标识、数据量门限和定时器时长中的一种或多种关联，进一步地，第一终端设备可以向第二设备发送该指示信息。通过该可能的实现方式，第一终端设备可以通过检测待传输数据是否满足触发条件，确定向第二设备发送该指示消息的具体时机。
在一个可能的实现中，第一终端设备接收第一配置消息之前，第一终端设备还可以向第三通信设备或第二设备发送第一信息，其中，该第一信息包括第一终端设备支持发送该指示信息的能力的信息。通过该可能的实现方式，第三通信设备或第二设备可以根据该第一信息判定第一终端设备具有发送指示信息的能力时，才会向第一终端设备发送第一配置消息，可以使得第一终端设备根据该第一配置消息配置(或激活)自身发送指示信息的功能。
在一个可能的实现中，指示信息中还包括侧行链路的物理信道的负载状态信息、待传输数据对应的传输时间信息和待传输数据对应的时延预算中的一种或多种。通过该可能的实现方式，第二设备可以确定获取目标资源的时间，进而避免了第二设备未接收到待传输数据时，过早地获取传输资源，造成对传输资源的浪费。
在一个可能的实现中，第三通信设备为网络设备或第三终端设备。通过实施该可能的实现方式，第二设备可以根据该第三通信设备的具体情景，获取针对待传输数据的目标资源。
第二方面，本申请提供一种资源调度方法，该方法可以应用于第二设备，也可以应用于第二设备的部件(芯片、处理器等)，以该方法应用于第二设备为示例，该方法包括：第二设备接收第一终端设备发送的指示信息，其中该指示信息包括侧行链路的待传输数据的数据量信息；第二设备根据待传输数据的数据量信息获取目标资源，其中，该目标资源用于第二设备向第三通信设备转发该第二设备从侧行链路接收到的数据。其中，第一终端设备与第二设备之间存在侧行链路，第二设备与第三通信设备之间存在连接。
基于第二方面所描述的方法，第二终端可以根据第一终端设备发送的指示信息中包括的侧行链路的待传输数据的数据量信息提前获取转发该待传输数据的所需的资源(即目标资源)，从而缩短第二设备接收第一终端设备的待传输数据与第二设备利用目标资源转发该待传输数据之间的时间差，即减小第二设备对第一终端设备发送的待传输数据的转发时延。
在一个可行的实现中，第二设备接收第一终端设备发送的指示信息之前，第二设备还可以接收第二配置消息，其中，该第二配置消息包括逻辑信道LCH和逻辑信道组LCG之间的对应关系、LCH标识、承载标识、LCG标识、数据量门限和定时器时长中的一种或多种。通过实施该可能的实现方式，可以保证第二设备针对该指示信息的内容与第一终端设备达成共识，保持对指示信息功能认知的一致性。

在一个可行的实现中，第二设备接收第一终端设备发送的指示信息之前，第二设备还可以接收第一终端设备发送的LCH的服务质量信息和/或LCH之间的映射关系；第二设备根据LCH的传输质量信息和/或LCH之间的映射关系确定第一配置消息；第二设备向第一终端设备发送第一配置消息，第一配置消息用于第一终端设备确定向第二设备发送的指示信息。通过实施该可能的实现方式，在第三通信设备是网络设备，而第三通信设备无法向第一终端设备发送第一配置消息时(例如，中继设备为利用层三中继的中继设备)，第二设备可以根据LCH的服务质量信息确定第一配置消息，并向第一终端设备发送第一配置消息，以保证第一终端设备可以根据该第一配置消息配置(或激活)自身发送指示信息的功能，削弱了侧行链路场景对中继设备的限定，扩大了中继设备的应用场景。或，在第三通信设备是为远端设备时，第二设备根据侧行链路LCH之间的映射关系来确定第一配置消息，并向第一终端设备发送该第一配置消息，以此保证第一终端设备可以根据该第一配置消息配置(或激活)自身通过侧行链路的PC5通信接口向中继设备发送指示信息的功能。
在一个可行的实现中，第二设备接收第二配置消息的具体实现方式为：第二设备接收第一终端设备发送的第二配置消息。通过实施该可能的实现方式，第二设备可以与第一终端设备保持对该指示信息内容和指示信息功能认知的一致性。
在一个可行的实现中，第二设备接收第二配置消息的具体实现方式为：第二设备接收第三通信设备发送的第二配置消息。通过实施该可能的实现方式，由第三通信设备直接向第二设备发送配置消息，提升第三通信设备对指示信息功能的配置效率。
在一个可行的实现中，第二设备根据待传输数据的数据量信息获取目标资源的具体实现方式为：第二设备根据待传输数据的数据量信息向第三通信设备发送提前缓存状态报告，其中，该提前缓存状态报告包括待传输数据的数据量信息，待传输数据的数据量信息用于第三通信设备为第二设备分配目标资源，目标资源用于向第三通信设备转发第二设备从侧行链路接收到的数据。通过实施该可能的实现方式，第二设备可以根据待传输数据的数据量信息提前向第三终端设备获取目标资源，从而保证第二设备从侧行链路中接收到第一终端设备发送的数据后，可以及时地利用目标资源对该数据进行转发，从而减小中继转发时延。
在一个可行的实现中，指示信息中还包括侧行链路的物理信道的负载状态信息、待传输数据对应的传输时间信息和待传输数据对应的时延预算中的一种或多种。通过实施该可能的实现方式，第二设备可以利用指示信息中的侧行链路的物理信道的负载状态信息、待传输数据对应的传输时间信息和待传输数据对应的时延预算的一种或多种确定获取目标资源的具体时间，进而避免第二设备未接收到待传输数据时，过早地获取传输资源，造成对传输资源的浪费。
在一个可行的实现中，第二设备向第一终端设备发送第一配置消息之前，第二设备接收第一终端设备发送的第一信息，该第一信息包括第一终端设备支持发送指示信息的能力的信息；其中，第二设备向第一终端设备发送第一配置消息的具体实现方式为：第二设备在根据第一信息确定第一终端设备有支持发送指示信息的能力时，向第一终端设备发送第一配置消息。通过该可能的实现方式，由第二设备向第一终端设备发送第一配置消息时，只有第二设备根据该第一信息确定第一终端设备具有发送指示信息的能力时，才会向第一终端设备发送第一配置消息，从而减少不必要的信令开销。
第三方面，本申请提供一种资源调度方法，该方法可以应用于第三通信设备，也可以 应用于第三通信设备的部件(芯片、处理器等)，以该方法应用于第三通信设备为示例，该方法包括：第三通信设备接收第二设备发送的提前缓存状态报告，其中，提前缓存状态报告由第二设备接收到第一终端设备发送的指示信息后生成，该提前缓存状态报告包括侧行链路的待传输数据的数据量信息；第三通信设备根据侧行链路的待传输数据的数据量信息为第二设备分配目标资源，该目标资源用于第二设备向第三通信设备转发该第二设备从侧行链路接收到的数据。其中，第一终端设备与第二设备之间存在侧行链路，第二设备与第三通信设备之间存在连接。
基于第三方面所描述的方法，第三通信设备根据第二设备发送的提前缓存状态报告中的侧行链路的待传输数据的数据量信息，提前为第二设备分配目标资源，使得第二设备可以利用该目标资源转发第二设备从侧行链路中接收到的数据，从而使得第三通信设备尽快地接收到第一终端设备发送的数据，提升了数据转发效率，降低了中继转发时延。

为了更好地理解本申请提供的方案，下面先对本申请的系统架构进行介绍：
本申请实施例提供的方法可以应用于各类通信系统中，例如，可以是物联网(internet of things，IoT)系统、窄带物联网(narrow band internet of things，NB-IoT)系统、长期演进(long term evolution，LTE)系统，也可以是第五代(5th-generation，5G)通信系统，还可以是LTE与5G混合架构、也可以是5G新无线(new radio，NR)系统，以及未来通信发展中出现的新的通信系统等。
请参见图1，图1是本申请实施例提供的一种资源调度系统架构的示意图。如图1所示，该系统架构包括第一终端设备101、第二设备102和第三通信设备103，其中，第一终端设备101与第二设备102之间存在侧行链路，第二设备102与第三通信设备103之间存在连接；第三通信设备103可以为网络设备1031或第三终端设备1032。需要了解的是，当第三通信设备为第三终端设备1032时，第二设备102与第三终端设备1032之间存在侧行链路连接；当第三通信设备103为网络设备1031时，第二设备102与网络设备1031之间存在Uu接口连接。

为了更好地理解本申请提供的方案，下面对本申请实施例涉及的相关术语进行介绍：
侧行链路(sidelink，SL)：请参见图2提供的NR V2X通信架构，其中，V2X用户设备(user equipment，UE)与另一个V2X UE之间的直连通信链路被定义为侧行链路或简称侧链。
PC5接口：请参见图2提供的NR V2X通信架构，V2X UE(即图中用户设备)之间进行通信的直连通信链路对应的通信接口被定义为PC5接口，V2X UE可以通过PC5接口传输V2X数据至另一个V2X UE。
Uu接口：请参见图2提供的NR V2X通信架构，V2X UE(即图中用户设备)和网络设备之间链路的通信接口被定义为Uu接口。在图2的通信场景中V2X UE之间进行通信可以为两种情形。情形1，V2X UE可以通过Uu接口将V2X数据发送至网络设备，网络设备将该V2X数据发送至网络设备对应的V2X应用服务器，进而，V2X应用服务器对V2X数据进行处理后发送至网络设备，再由网络设备通过Uu接口将V2X数据发送至另一V2X UE。情形2，V2X UE通过侧行链路的PC5接口直接将V2X数据发送至另一V2X UE。
Mode1：发送侧用户设备(transmission user equipment，Tx UE)处于连接态(即，Tx UE与网络设备连接)时，Tx UE向网络设备发送侧行链路缓存状态报告(sidelinkbufferstatus report，SL-BSR)，以使网络设备为发送侧用户设备分配侧行链路传输资源，这样的获取传输资源的方式被称为Mode1。
Mode2：Tx UE可以处于空闲态(即，Tx UE与网络设备未连接)/连接态/非激活态(Inactive态)，Tx UE从自身配置的资源池中选择(确定)传输资源用以传输逻辑信道中的待传输的侧行链路数据，这样的获取传输资源的方式被称为Mode2。
中继设备(relay user equipment，Relay UE)：在V2X通信网络架构中，用于将从Remote UE接收到的数据中继转发至接收侧用户设备(receptionuser equipment，Rx UE)，从而保证Remote UE与Rx UE进行通信的设备被称为中继设备，即中继设备是具有中继功能的通信设备，包括但不限于具有中继功能的用户设备。
远端设备(remote user equipment，Remote UE)：在V2X通信网络架构中，不能与Rx UE直接通信，仅能通过具有中继设备转发数据来与Rx UE进行间接通信的用户设备。
逻辑信道(logical channel，LCH)：是在物理信道上传递不同信息种类构成的信道。逻辑信道可以分为控制信道和业务信道，其中，控制信道用于传输控制平面信息，业务信道用于传输用户平面信息，即，控制信道用于传输信令或同步数据，业务信道用于传输编码及加密后的业务数据。
逻辑信道组(logical channel group，LCG)：一个逻辑信道组可以包含多个逻辑信道。通常可以按逻辑信道的服务质量等级将不同的逻辑信道划分至一个或多个逻辑信道组。
层二中继(layer 2 relay，L2R)：中继设备为层二中继时通常包含媒体访问控制(medium access control，MAC)层功能和无线链路控制(radio link control，RLC)层功能，有时在RLC层之上还可以包括其他层，如带宽分配协议(bandwidth allocationprotocol，BAP)层等进行转发控制的协议层，Remote UE发送的数据通常在RLC层或其他协议层进行转发处理。在这种采取层二中继的情况下，网络设备通常可以对中继设备和远端设备进行下发配置参数进行控制。

下面对本申请实施例提供的资源调度方法进一步进行详细描述：
请参见图3，图3是本申请实施例提供的一种资源调度方法的流程示意图。如图3所示，该资源调度方法的包括如下步骤301～步骤302。图3所示的方法执行主体可以为第一终端设备和第二设备，或主体可以为第一终端设备中的芯片和第二设备中的芯片。图3以第一终端设备和第二设备为方法的执行主体为例进行说明。其中：
301、第一终端设备向第二设备发送指示信息，其中，该指示信息包括侧行链路的待传输数据的数据量信息，该待传输数据的数据量信息用于第二设备获取目标资源，该目标资源用于第二设备向第三通信设备传输(或转发)从该侧行链路接收到的数据。
其中，第一终端设备是远端设备，第二设备是中继设备。第一终端设备和第二设备之间存在侧行链路，第二设备与第三通信设备之间存在连接，需要知晓的是，第二设备与第三通信设备之间存在的连接为通信连接。
第一终端设备和第二设备之间的侧行链路对应的逻辑信道中有待传输数据时，第一终端设备可以获取该待传输数据的数据量信息，并根据该待传输数据的数据量信息向第二设备发送指示信息，例如，该指示信息可以称之为侧行链路缓存状态指示(sidelinkbuffer status indication，SL-BSI)。该指示信息中包括的待传输数据的数据量信息可以是数据量的大小，例如可以是以比特或字节为单位的数值，或者可以是数据量范围的一个索引值，在索引值为1时表示数据量大小在1字节到10字节之间；具体实施时，对指示信息中包括的待传输数据的数据量信息的表现形式不做限定。
302、第二设备接收第一终端设备发送的指示信息，并根据该待传输数据的数据量信息获取目标资源。
本步骤以接收第一终端设备发送的指示信息为SL-BSI为示例，第二设备接收第一终端设备发送的SL-BSI，进一步地，可以从SL-BSI中获取侧行链路中待传输数据的数据量信息，进而，根据该待传输数据的数据量信息获取目标资源。其中，第三通信设备为网络设备时，第二设备获取的目标资源为Uu传输资源；第三通信设备为第三终端设备(即另一Remote UE)时，第二设备获取的目标资源为侧行链路传输资源。
可见，通过实施图3所描述的资源调度方法，第一终端设备可以通过发送指示信息至第二设备，使第二设备预先知晓即将接收到的侧行链路的待传输数据的数据量信息，进而，第二设备可以根据该侧行链路的待传输数据的数据量信息提前获取传输资源，避免了第一终端设备将侧行链路的待传输数据传输至第二设备，第二设备再根据该待传输数据的数据量信息获取传输资源的情况，从而减小了第二设备转发待传输数据的时延，即降低中继转发时延，提升了第二设备对数据的转发效率。
请参见图4，图4是本申请实施例提供的另一种资源调度方法的流程示意图。如图4所示，该资源调度方法包括如下步骤。其中：
401、第一终端设备接收第一配置消息，并根据该第一配置消息确定向第二设备发送指示信息。
第一终端设备接收第一配置消息，其中，第一配置消息中可以包含有触发第一终端设备发送该指示信息的触发条件或该指示信息的数据内容，进而，第一终端设备可以根据该第一配置消息中的触发第一终端设备发送该指示信息的触发条件确定向第二设备发送指示信息。即第一终端设备接收第一配置消息之后，可以根据第一配置消息确定何时向第二设备发送指示信息，和/或第一终端设备可以根据第一配置消息确定向第二设备发送包含哪些数据内容的指示信息。其中，指示信息的触发条件是指触发第一终端设备向第二设备发送指示信息的触发条件，指示信息的数据内容为指示信息中携带的数据内容。
在一个可能的实现中，第一配置消息包括LCH和LCG之间的对应关系、LCH标识、承载标识、LCG标识、数据量门限和定时器时长中的一种或多种。在这种情况下，触发条件与LCH标识、承载标识、LCG标识、数据量门限和定时器时长中的一种或多种相关联。
其中，LCH标识可以是LCH编码或名称等字符串，LCH标识对应唯一LCH。LCG标识可以是LCG编码或名称等字符串，LCG标识对应唯一LCG。承载标识为承载编码或名称等字符串，承载标识对应唯一承载。LCH和LCG之间的对应关系可以是指LCG标识与LCH标识的对应关系，例如Remote UE(即前述第一终端设备)被配置有LCH1、LCH2、LCH3、LCH4、LCH5、LCH6，而第一配置消息中包含有将LCH1、LCH2、LCH3分配至LCG1(即 LCH1、LCH2、LCH3对应于LCG1)，将LCH4、LCH5、LCH6分配至LCG2(即LCH4、LCH5、LCH6对应于LCG2)。数据量门限是指LCH或LCG的数据量对应的数值，例如，LCG1对应的数据量门限为X字节，则当LCG1的数据量超过或等于X字节时，第一终端设备向第二设备发送指示信息，其中X为大于等于1的正整数。
示例性地，在一个示例中，第一配置消息包括LCH标识：LCH1和LCH2，在这种情况下，触发条件为LCH1/LCH2中存在待传输数据，即第一终端设备接收第一配置消息后，当LCH1和/或LCH2有待传输数据时，第一终端设备向第二设备发送指示信息，该指示消息中携带有LCH1和/或LCH2中待传输数据的数据量信息。通过这样的方法，提升了部分LCH的优先级，当该LCH具有待传输数据时，可以根据该LCH的待传输数据的数据量信息优先获取目标数据，以达到优先传输该LCH的待传输数据的目的。
示例性地，在另一个示例中，第一配置消息包括LCG标识：LCG1和LCG2，在这种情况下，触发条件为LCG1/LCG2中存在待传输数据，即第一终端设备接收第一配置消息后，当LCG1和/或LCG2有待传输数据时，则第一终端设备向第二设备发送指示信息，该指示消息中携带有LCG1和/或LCG2中待传输数据的数据量信息。通过这样的方法，提升了部分LCG的优先级，当该LCG具有待传输数据时，可以根据该LCG的待传输数据的数据量信息优先获取目标数据，以达到优先传输该LCG的待传输数据的目的。
示例性地，在又一个示例中，第一配置消息中包括LCH和LCG之间的对应关系，如LCG1对应有LCH1、LCH2和LCH3，在这种情况下，第一终端设备接收第一配置消息后，第一终端设备根据第一配置消息将LCH1、LCH2和LCH3分配至LCG1中，第一终端设备向第二设备发送指示信息，该指示消息中携带有LCG1(即LCH1、LCH2和/或LCH3)的待传输数据的数据量信息。通过这样的方法，可以将LCH按照实际应用场景中的情形进行分组得到LCG，以提升在实际应用场景中指示信息的适应性。
示例性地，在又一个示例中，第一配置消息包括承载标识：承载1和承载2，在这种情况下，触发条件为承载1/承载2中存在待传输数据，即第一终端设备接收第一配置消息后，当承载1或承载2有待传输数据时，第一终端设备向第二设备发送指示信息，该指示消息中携带有承载1和承载2的待传输数据的数据量信息。通过这样的方法，提升了部分承载的优先级，当该承载具有待传输数据时，可以根据该承载的待传输数据的数据量信息优先获取目标数据，以达到优先传输该承载的待传输数据的目的。
示例性地，在又一个示例中，第一配置消息包括数据量门限X字节和LCH1标识或LCG1标识，在这种情况下，触发条件为LCH1中有大于等于X字节的待传输数据或LCG1中有大于等于X字节的待传输数据，即第一终端设备接收第一配置消息之后，第一终端设备在LCH1或LCG1的待传输数据量大于或等于X字节时，第一终端设备向第二设备发送指示信息，该指示消息中携带有LCH1或LCG1的待传输数据的数据量信息。通过这样的方法，当LCH/LCG中的待传输数据的数据量超过数据量门限时，才发送指示信息指示第二设备获取目标资源，避免了LCH/LCG中有数据就会发送的指示信息导致指示信息发送频繁，造成传输资源浪费的情况。
示例性地，在又一个示例中，第一配置消息包括定时器时长T，在这种情况下，触发条件为第二指示信息与第一指示信息之间的时间间隔大于或等于定时器时长T，即第一终端设备向第二设备发送第一指示信息后，第一终端设备在定时器时长T内不会再向第二设备发送第二指示信息，换而言之，第一终端设备向第二设备发送的第一指示信息和第二指 示信息之间的间隔时长大于或等于定时器时长T。其中，定时器时长T的具体数值可以由开发人员根据实验场景测算得到，后期根据具体应用场景进行相应的调整，也可以是有第一终端设备根据LCH或LCG的服务质量信息或负载情况(如信道忙碌比信息)等进行动态调整，对此本申请不做具体限定。通过这样的方法，可以避免第一终端设备频繁向第二设备发送指示信息而造成资源浪费的情况。
在一个应用场景中，如图5a所示为远端设备与网络设备通信的场景示意图，其中，第三通信设备为网络设备503，第一终端设备是远端设备501，第二设备是中继设备502。远端设备501和中继设备502之间存在侧行链路，中继设备502与网络设备503之间存在连接。在这种情况下，若中继设备502为使用层二中继的中继设备，在这种情况下，网络设备可向第一终端设备和第二设备发送配置消息。即，第一终端设备接收的第一配置消息可以由第三通信设备(网络设备503)发送，还可以由第三通信设备(网络设备503)指示第二设备根据第二配置消息确定并发送。若中继设备502为使用层三中继的中继设备，此时第一终端设备接收的第一配置消息可以由第二设备(中继设备502)根据远端设备501与中继设备502之间的侧行链路中LCH的服务质量信息确定。其中，LCH的服务质量信息(quality of service，QoS)是指该逻辑信道所承载的业务数据所需要保障的服务质量要求，对应有包括优先级、业务可用性、延迟、延迟抖动、吞吐量、误码和丢包率等一个或多个因素的一套度量指标，可量化为等级。
在另一个场景中，如图5b所示为远端设备与远端设备通信的场景示意图，其中，第三通信设备为远端设备506，第一终端设备是远端设备504，第二设备是中继设备505。远端设备504和中继设备505之间存在侧行链路，中继设备505与远端设备506之间存在连接，且中继设备505处于连接态(即与网络设备相连接)。在这种情况下，此时第一终端设备接收的第一配置消息由第二设备(中继设备505)根据侧行链路1(远端设备506和中继设备505之间侧行链路)的LCH与侧行链路2(远端设备504和中继设备505之间侧行链路)的LCH之间的映射关系确定。
在又一个场景中，如图5c所示为远端设备与远端设备通信的场景示意图，其中，第三通信设备为远端设备509，第一终端设备是远端设备507，第二设备是中继设备508。远端设备507和中继设备508之间存在侧行链路，中继设备508与远端设备509之间存在连接，且中继设备508处于空闲态(即未连接网络设备)。在这种情况下，此时第一终端设备接收的第一配置消息由第二设备(中继设备508)根据侧行链路1(远端设备507和中继设备508之间侧行链路)的LCH与侧行链路2(远端设备509和中继设备508之间侧行链路)的LCH之间的映射关系确定的。
402、第二设备接收第二配置消息。
其中，第二配置消息包括LCH和LCG之间的对应关系、LCH标识、承载标识、LCG标识、数据量门限和定时器时长中的一种或多种。
第二设备接收第二配置消息，根据该第二配置消息与第一终端设备就前述指示信息的数据格式内容达成统一共识。换而言之，第二设备知晓自身接收到的指示信息中应该包含何种数据内容，例如，第二配置消息中包括LCH1标识，在这种情况下，第一终端设备发送的指示信息中携带有LCH1的待传输数据的数据量信息，第二设备可以接收携带有LCH1的待传输数据的数据量信息的指示信息。
在一个应用场景中，如图5a所示为远端设备与网络设备通信的场景示意图，其中，第 三通信设备为网络设备503。在这种情况下，若中继设备502为使用层二中继的中继设备，第二设备接收的第二配置消息可以由第三通信设备(网络设备503)发送；还可以由第三通信设备(网络设备503)指示第一终端设备根据第一配置消息确定并发送的。
应知晓的是，步骤402和步骤401的执行顺序不分先后，在本实施例中仅为示意，对此不做具体限定。换而言之，执行顺序还可以为先执行步骤402再执行步骤401，或同时执行步骤401和步骤402。
在一个可能的实现中，第二设备接收第三配置消息，其中，该第三配置消息包括针对pre-emptive BSR机制和/或提前侧行链路缓存状态报告(pre-emptive sidelink bufferstatus report，pre-emptive SL-BSR)机制的激活参数，例如usePreBSR参数和/或use SL-BSR参数。其中，第二设备可以根据第三配置消息中的use PreBSR参数激活自身的pre-emptive BSR机制，和/或，根据第三配置消息中的use SL-BSR参数激活自身的pre-emptive SL-BSR机制。需要知晓的是，第三配置消息可以是前述第二配置消息，也可以是除前述第二配置消息的其他配置消息，对此本申请不做具体限定。其中，pre-emptive BSR机制为：UE向网络设备发送pre-emptive BSR以获取Uu传输资源的机制。pre-emptive SL-BSR机制为第二设备向网络设备发送pre-emptive SL-BSR以提前侧行链路传输资源的机制。
403、第一终端设备向第二设备发送指示信息，其中，该指示信息包括侧行链路的待传输数据的数据量信息。
第一终端设备根据步骤401的具体实现方式确定指示信息，并将该指示信息发送至第二设备，其发送指示信息的具体实现方式可参见前述实施例步骤301的具体实现方式，此处不再进行过多赘述。
404、第二设备接收第一终端设备发送的指示信息，并根据该待传输数据的数据量信息获取目标资源，该目标资源用于第二设备向第三通信设备传输从该侧行链路接收到的数据。
第二设备接收第一终端设备发送的指示信息后，从该指示信息中获取第一终端设备的待传输数据的数据量信息，并获取能够向第三通信设备传输该待传输数据的目标资源。其中，第三通信设备为网络设备时，目标资源为Uu传输资源；第三通信设备为第三终端设备(另一远端设备)时，目标资源为侧行链路传输资源。
在一个应用场景中，如图5a所示为远端设备与网络设备通信的场景示意图，其中，第三通信设备为网络设备503，第一终端设备是远端设备501，第二设备是中继设备502。远端设备501和中继设备502之间存在侧行链路，中继设备502与网络设备503之间存在连接。在这种情况下，第二设备根据前述第三配置消息激活自身的pre-emptive BSR机制。进而，第二设备在接收第一终端设备发送的SL-BSI后，可以根据SL-BSI中的侧行链路的待传输数据的数据量信息向第三通信设备(网络设备503)发送pre-emptive BSR，以获取第三通信设备(网络设备503)分配的目标资源。
在另一个场景中，如图5b所示为远端设备与远端设备通信的场景示意图，其中，第三通信设备为远端设备506，第一终端设备是远端设备504，第二设备是中继设备505。远端设备504和中继设备505之间存在侧行链路，中继设备505与远端设备506之间存在连接，且中继设备505处于连接状态(即与网络设备相连接)。在这种情况下，第二设备根据前述第三配置消息激活自身的pre-emptive SL-BSR机制。进而，第二设备在接收第一终端设备发送的SL-BSI后，可以根据SL-BSI中的侧行链路的待传输数据的数据量信息向网络设备发送 pre-emptive SL-BSR，以获取传输该侧行链路的待传输数据的目标资源。即，此种情况下，中继设备通过Mode1方式获取传输资源，并利用该传输资源向远端设备506转发从侧行链路接收到的数据。
在又一个场景中，如图5c所示为远端设备与远端设备通信的场景示意图，其中，第三通信设备为远端设备509，第一终端设备是远端设备507，第二设备是中继设备508。远端设备507和中继设备508之间存在侧行链路，中继设备508与远端设备509之间存在连接，且中继设备508处于空闲态(即未连接网络设备)。在这种情况下，第二设备在接收第一终端设备发送的SL-BSI后，可以根据SL-BSI中的侧行链路的待传输数据的数据量信息从自身资源池中确定出传输该侧行链路的待传输数据的目标资源。即，此种情况下，中继设备通过Mode2方式获取传输资源，并利用该传输资源向远端设备509转发从侧行链路接收到的数据。
可见，通过实施图4所描述的资源调度方法，第一终端设备接收第一配置消息，并根据该第一配置消息确定向第二设备发送指示信息，即第一终端设备可以通过第一配置消息激活向中继设备发送SL-BSI的功能，并确定SL-BSI的内容。第二设备接收第二配置信息，以达成第一终端设备对SL-BSI包含数据内容的共识。进而，第二设备接收到第一终端设备发送的SL-BSI后，可以根据该待传输数据的数据量信息更精确地获取目标资源，并利用该目标资源向第三通信设备转发第二设备从该侧行链路接收到的数据。
请参见图6，图6是本申请实施例提供的远端设备与网络设备通信场景下的一种资源调度方法的流程示意图。该远端设备与网络设备通信场景如图5a所示，第三通信设备为网络设备503，第一终端设备是远端设备501，第二设备是中继设备502。远端设备501和中继设备502之间存在侧行链路，中继设备502与网络设备503之间存在连接。该资源调度方法包括如下如图6所示的如下步骤。其中：
601、第一终端设备接收第三通信设备发送的第一配置消息。
其中，该第一配置消息用于第一终端设备确定向第二设备发送指示信息，该第一配置消息包括LCH和LCG之间的对应关系、LCH标识、承载标识、LCG标识、数据量门限和定时器时长中的一种或多种。
在一个可能的实现方式中，在第一终端设备接收第三通信设备发送的第一配置消息之前，第一终端设备向第三通信设备发送第一信息，该第一信息包括第一终端设备支持发送指示信息的能力的信息。第三通信设备接收第一终端设备发送的第一信息，并在根据该第一信息确定第一终端设备有支持发送指示信息的能力时，第三通信设备向第一终端设备发送第一配置消息。示例性地，该第一信息中携带有第一参数，例如第一信息中携带有参数supportSL-BSI，则表示第一终端设备支持发送指示信息。在这种情况下，第一终端设备向第三通信设备发送第一信息，若第三通信设备接收该第一信息后，检测到第一信息中携带第一参数，可确定该第一终端设备具有发送指示信息的能力，进而，可以向第一终端设备发送第一配置消息。若第三通信设备接收该第一消息后，检测到第一信息中未携带第一参数，则可确定该第一终端设备不具有发送指示信息的能力，进而不会发送第一配置消息至第一终端设备。
在一个可能的实现中，第二设备接收第三配置消息，其中，该第三配置消息包括针对pre-emptive BSR机制的激活参数，例如use PreBSR参数。其中，第二设备可以根据第三配置消息中的use PreBSR参数激活自身的pre-emptive BSR机制。其中，pre-emptive BSR机制 为：UE向网络设备发送pre-emptive BSR以获取Uu传输资源的机制。
602、第一终端设备根据该第一配置消息确定第二配置消息。
第一终端设备从第一配置消息包括的LCH和LCG之间的对应关系、LCH标识、承载标识、LCG标识、数据量门限和定时器时长中的一种或多种中确定出第二配置消息包括的内容。其中，该第二配置消息包括LCH和LCG之间的对应关系、LCH标识、承载标识、LCG标识中的一种或多种。
示例性地，若第一配置消息包括LCH和LCG之间的对应关系和LCG标识时，则确定第二配置消息包括LCH和LCG之间的对应关系和LCG标识。若第一配置消息包括LCH和LCG之间的对应关系和LCG标识，还包括数据量门限和/或定时器时长，则确定第二配置消息包括LCH和LCG之间的对应关系和LCG标识。若第一配置消息中包括LCH标识，则确定第二配置消息包括LCH标识。若第二配置消息包括LCH标识，还包括数据量门限和/或定时器时长，则确定第二配置消息包括LCH标识。
603、第一终端设备向第二设备发送第二配置消息。
604、第一终端设备根据该第一配置消息确定向第二设备发送指示信息，其中，该指示信息包括侧行链路的待传输数据的数据量信息。
第一终端根据第一配置消息确定向第二设备发送指示信息，示例性地，在一个示例中，第一配置消息包括LCH标识，表示指示信息中可以包括哪些LCH的数据量信息。例如第一配置消息包括：LCH1和LCH2，在这种情况下，当第一终端设备向第二设备发送指示信息时，该指示消息中携带有LCH1和LCH2中待传输数据的数据量信息。
在另一个示例中，第一配置消息包括LCG标识，表示指示信息中可以包括哪些LCG的信息。例如第一配置消息包括：LCG1和LCG2，在这种情况下，当第一终端设备向第二设备发送指示信息时，该指示消息中携带有LCG1和LCG2中待传输数据的数据量信息。
在又一个示例中，第一配置消息中包括LCH和LCG之间的对应关系，如LCG1对应有LCH1、LCH2和LCH3，在这种情况下，第一终端设备接收第一配置消息后，第一终端设备根据第一配置消息将LCH1、LCH2和LCH3分配至LCG1中，当第一终端设备向第二设备发送指示信息，如果LCH1/LCH2/LCH3中有待传输数据，则该指示消息中携带有LCG1的待传输数据的数据量信息。
在又一个示例中，第一配置消息包括可以触发第一终端设备发送指示信息的LCH/LCG/承载的标识。例如第一配置消息包括：LCH1和LCH2，在这种情况下，则第一终端设备接收第一配置消息后，当LCH1或LCH2有待传输数据时，第一终端设备触发向第二设备发送指示信息，需要注意的是，该第一终端设备触发向第二设备发送指示信息是指第一终端设备可以或需要向第二设备发送指示信息，而不是第一终端设备向第二设备发送指示信息，具体第一终端设备还需要在有可用传输资源(即将该指示信息传输至第二设备的传输资源)时才能生成指示信息并向第二设备发送。
在又一个示例中，第一配置消息包括数据量门限和LCH/LCG/承载的标识，表示当该LCH标识指示的LCH/该LCG标识指示的LCG/该承载标识指示的承载中待传输数据量超过所指示数据量门限时，第一终端设备可以触发向第二设备发送指示信息。例如第一配置信息中包括数据量门限X字节和LCH1/LCG1的标识，则当第一终端设备在LCH1或LCG1的待传输数据量大于或等于X字节时，第一终端设备触发向第二设备发送指示信息。
在又一个示例中，第一配置消息包括定时器时长T，在这种情况下，第一终端设备向 第二设备发送第一指示信息后，会启动一个定时器，在定时器运行时，第一终端设备不会再向第二设备发送第二指示信息，定时器超时后才可以向第二设备发送指示信息，换而言之，第一终端设备向第二设备发送的第一指示信息和第二指示信息之间的间隔时长大于或等于定时器时长T。其中，定时器时长T的具体数值可以由开发人员根据实验场景测算得到，后期根据具体应用场景进行相应的调整，也可以是有第一终端设备根据LCH或LCG的服务质量信息或负载情况(如信道忙碌比信息)等进行动态调整，对此本申请不做具体限定。
在又一个示例中，第一终端设备可以重用现有的SL-BSR的触发条件作为触发向第二设备发送指示信息，比如重用regular SL-BSR和/或periodic SL-BSR的触发条件，即，当第一终端设备有新数据到达，该新数据所属LCH的优先级高于其他有待传输数据的LCH的优先级，或当前没有其他LCH有待传输数据时，则触发该第一终端设备向第二设备发送指示信息，该指示信息中包括前述新数据的数据量信息。
605、第一终端设备向第二设备发送指示信息。
第一终端设备向第二设备发送根据第一配置消息确定出的指示信息。
在一个应用场景中，当第一终端设备已经生成或发送了该指示信息后，可以取消已经触发了的指示信息。示例性地，当第一终端设备将待传输数据量利用传输资源将待传输数据发送至第二设备时，第一终端设备可以取消自身已经触发了的指示信息，换而言之，第一终端设备在传输该指示信息中的数据量信息对应的待传输数据时，不会再次触发向第二设备发送指示信息。
606、第二设备接收第一终端设备发送的指示信息，并向第三通信设备发送提前缓存状态报告，该提前缓存状态报告包括该待传输数据的数据量信息。
第二设备接收第一终端设备发送的指示信息之后，第二设备根据该指示信息中的待传输数据的数据量信息向第三通信设备发送pre-emptive BSR，即该pre-emptive BSR携带有待传输数据的数据量信息。
607、第三通信设备接收该提前缓存状态报告，并根据该待传输数据的数据量信息为第二设备分配目标资源(即Uu接口对应的Uu传输资源)。
第三通信设备接收该pre-emptive BSR之后，根据pre-emptive BSR携带的待传输数据的数据量信息为第二设备分配目标资源(即Uu接口对应的Uu传输资源)。
608、第二设备接收第一终端设备发送的待传输数据。
第一终端设备向第二设备发送指示消息后，则第一终端设备向第二设备发送待传输数据。第三通信设备接收第二设备发送的pre-emptive BSR之后，根据pre-emptive BSR携带的待传输数据的数据量信息为第二设备分配目标资源。第二设备接收到待传输数据的时间与目标资源的时间之间的先后顺序不做具体限定。
在一个可能的实现中，前述指示信息中还包括辅助信息，该辅助信息包括该侧行链路的物理信道的负载状态信息、待传输数据对应的传输时间信息和待传输数据对应的时延预算中的一种或多种。例如，该辅助信息可被第二设备用于确定获取目标资源的时间。
其中，物理信道的负载状态信息可以为：若第一终端设备检测传输信道的负载超过过载门限，则确定物理信道的负载状态信息为信道拥塞；若第一终端设备检测物理信道的负载小于或等于过载门限，则确定该物理信道的负载状态信息为信道畅通。或者物理信道的负载状态信息可以为信道忙碌情况，如为信道忙碌比(channel busy ratio，CBR)。待传输数据对应的传输时间信息可以是以ms/us/时隙/符号为单位的时间值，例如可以由第一终端 设备根据待传输数据的数据量信息和物理信道的传输速率计算得到，例如，可以用待传输数据的数据量信息与物理信道传输速率的比值表示，或者当第一终端设备采用mode 2方式获取资源时，待传输数据对应的传输时间信息可以为第一终端设备预留到传输资源所用的时间，或从第一终端设备生成数据包到利用预留资源开始或完成数据传输所需的时间等。时延预算：待传输数据的数据包的总时延预算，如数据包从第一终端设备传输到第三通信设备之间的时延需求，或待传输数据包的剩余时间信息。
在本实施例中，由于第三通信设备为网络设备(或接入网设备)，第一终端向第二终端发送指示信息，第二设备根据指示信息中的辅助信息确定获取目标资源的时间，即，第二设备可以根据指示信息中的辅助信息确定向第三通信设备触发和/或发送pre-emptive BSR的时间。
示例性地，指示信息中包括物理信道的负载状态信息，其中，负载状态信息包括信道拥塞或信道畅通，或信道忙碌比信息等。其中，信道拥塞时，对应预设获取目标资源的时长为100ms；信道畅通时，对应预设获取目标资源的时长为50ms。在这种情况下，若该物理信道的负载状态信息为信道拥塞，则第二设备接收到第一终端设备发送的指示信息后开启计时，当100ms到达时，第二终端向第三通信设备发送pre-emptive BSR以获取目标资源。若该物理信道的负载状态信息为信道畅通，则第二设备接收到第一终端设备发送的指示信息后开启计时，当50ms到达时，第二终端向第三通信设备发送pre-emptive BSR以获取目标资源。
示例性地，指示信息中包括待传输数据对应的传输时间信息。假设开发人员通过实验数据测算可得第三通信设备接收pre-emptive BSR后为第二设备分配目标资源的时长为30ms，第一终端设备向第二设备发送指示信息，该指示信息包括的待传输数据对应的传输时间信息为100ms，则第二设备可以在接收到第一终端设备发送的指示信息后开启计时，当70ms到达时，第二终端向第三通信设备发送pre-emptive BSR以获取目标资源。
示例性地，指示信息中包括时延预算。假设开发人员通过实验数据测算可得第三通信设备接收pre-emptive BSR后为第二设备分配目标资源的时长为30ms，第一终端设备向第二设备发送指示信息，该指示信息包括的时延预算为80ms，则第二设备可以在接收到第一终端设备发送的指示信息后，至少在50ms以内，第二终端需向第三通信设备发送pre-emptive BSR以获取目标资源。
609、第二设备利用该目标资源向第三通信设备(网络设备)传输从所述侧行链路上接收到的数据(即前述待传输数据)。

在一个可能的实现方式中，在第一终端设备接收第二设备发送的第一配置消息之前，第一终端设备向第二设备发送第一信息，该第一信息包括第一终端设备支持发送指示信息的能力的信息。第二设备接收第一终端设备发送的第一信息，并在根据该第一信息确定第一终端设备有支持发送指示信息的能力时，第二设备向第一终端设备发送第二配置消息。示例性地，该第一信息中携带有第一参数，例如第一信息中携带有参数supportSL-BSI，则表示第一终端设备支持发送指示信息。在这种情况下，第一终端设备向第二设备发送第一信息，若第二设备接收该第一信息后，检测到第一信息中携带有第一参数，可确定该第一终端设备具有发送指示信息的能力，进而，可以向第一终端设备发送第一配置消息。若第二设备接收该第一消息后，检测到第一信息中未携带第一参数，可确定该第一终端设备不具有发送指示信息的能力，则不会发送第一配置消息至第一终端设备，节省通信传输资源。
在一个可行的实现方式中，第二设备接收第三配置消息，其中，该第三配置消息包括针对pre-emptive SL-BSR机制的激活参数，例如use SL-BSR参数。其中，第二设备可以根据第三配置消息中的use SL-BSR参数激活自身的pre-emptive SL-BSR机制。该pre-emptive SL-BSR机制为第二设备向网络设备发送pre-emptive SL-BSR以提前侧行链路传输资源的机 制。

1004、第二设备接收第一终端设备发送的指示信息，并向网络设备发送提前侧行链路缓存状态报告，该提前侧行链路缓存状态报告包括该侧行链路的待传输数据的数据量信息。
第二设备接收第一终端设备发送的指示信息之后，第二设备根据该指示信息中的待传输数据的数据量信息向网络设备发送提前侧行链路缓存状态报告(pre-emptive SL-BSR)，即该pre-emptive SL-BSR携带有待传输数据的数据量信息。

在本实施例中，第二设备可以根据指示信息中的辅助信息确定向网络设备发送pre-emptive SL-BSR的时间。
示例性地，指示信息中包括物理信道的负载状态信息，其中，负载状态信息包括信道拥塞或信道畅通，或信道忙碌比信息。其中，信道拥塞时，对应预设获取目标资源的时长为100ms；信道畅通时，对应预设获取目标资源的时长为50ms。在这种情况下，若物理信道的负载状态信息为信道拥塞，则第二设备接收到第一终端设备发送的指示信息后开启计时，当100ms到达时，第二设备向网络设备发送pre-emptive SL-BSR以获取目标资源。若物理信道的负载状态信息为信道畅通，则第二设备接收到第一终端设备发送的指示信息后开启计时，当50ms到达时，第二终端向网络设备发送pre-emptive SL-BSR以获取目标资源。
示例性地，指示信息中包括待传输数据对应的传输时间信息。假设开发人员通过实验 数据测算得到网络设备接收pre-emptive SL-BSR后为第二设备分配目标资源的时长为30ms，第一终端设备向第二设备发送指示信息，该指示信息包括的待传输数据对应的传输时间信息为100ms，则第二设备可以在接收到第一终端设备发送的指示信息后开启计时，当70ms到达时，第二设备向网络设备发送pre-emptive SL-BSR以获取目标资源。
示例性地，指示信息中包括时延预算。假设开发人员通过实验数据测算可得网络设备接收pre-emptive SL-BSR后为第二设备分配目标资源的时长为30ms，第一终端设备向第二设备发送指示信息，该指示信息包括的时延预算为80ms，则第二设备可以在接收到第一终端设备发送的指示信息后开启计时，当50ms到达时，第二终端向网络设备发送pre-emptive SL-BSR以获取目标资源。
1005、第二设备接收网络设备根据该侧行链路的待传输数据的数据量信息分配的目标资源(即侧行链路传输资源)。
网络设备根据pre-emptive SL-BSR中携带的待传输数据的数据量信息为第二设备分配目标资源。
1006、第二设备接收第一终端设备发送的待传输数据。
第一终端设备向第二设备发送指示消息后，则第一终端设备向第二设备发送待传输数据。网络设备接收第二设备发送的pre-emptive SL-BSR之后，根据pre-emptive SL-BSR携带的待传输数据的数据量信息为第二设备分配目标资源(即侧行链路传输资源)。第二设备接收到待传输数据的时间与目标资源的时间之间的先后顺序不做具体限定。
1007、第二设备利用该目标资源向第三通信设备(另一个远端设备)传输待传输数据(即第二设备从侧行链路中接收到的数据)。
第二终端在获取到目标资源和待传输数据之后，利用该目标资源向第三通信设备(网络设备)传输待传输数据。
可见，通过实施例图10所描述的资源调度方法，第三通信设备为远端设备，在第二设备(中继设备)处于连接态时，第二设备通过发送pre-emptive SL-BSR以使网络设备为第二设备分配侧行链路传输资源，进而在侧行链路通信场景中减小中继转发时延。
请参见图11，图11是本申请实施例提供的远端设备与远端设备通信场景下的另一种资源调度方法的流程示意图。该远端设备与远端设备通信场景如图5c所示，第三通信设备为远端设备509，第一终端设备是远端设备507，第二设备是中继设备508。远端设备507和中继设备508之间存在侧行链路，中继设备508与远端设备509之间存在连接，且中继设备508采用mode 2方式获取传输资源。该资源调度方法包括如下如图11所示的如下步骤。其中：
1101、第一终端设备接收第二设备发送的第一配置消息。
1102、第一终端设备根据该第一配置消息确定向第二设备发送指示信息，其中，该指示信息包括侧行链路的待传输数据的数据量信息。
1103、第一终端设备向第二设备发送指示信息。
其中，步骤1101-步骤1102的具体实施方式可参见前述实施例步骤1001-步骤1003的具体实施方式，在此不再进行过对赘述。
1104、第二设备接收第一终端设备发送的指示信息，并根据该侧行链路的待传输数据的数据量信息从可用侧行链路资源池中确定出目标资源(即侧行链路资源)。
第二设备接收第一终端设备发送的指示信息之后，第二设备根据该指示信息中的待传 输数据的数据量信息，可以触发进行资源选择或资源重选过程，例如从自身配置的资源池中预留传输该待传输数据的目标资源(即侧行链路资源)。
示例性的，第二设备在成功解析到第一终端设备发送的指示信息，触发第二设备预留目标资源。应知晓的是，即使此刻第二设备针对远端设备还没有待传输的数据(即，远端设备还未将待传输数据传输至第二设备，仅向第二设备发送指示待传输数据的数据量信息的指示信息)时，或者当第二设备接收到指示信息，根据指示信息中的数据量信息判定当前第二设备预留的资源已经足够传输当前已接收到的待转发数据(即待传输数据)，第二设备也会触发去预留目标资源。
在又一个示例中，当第二设备在成功解析到第一终端设备发送的指示信息，根据指示信息中的数据量信息发现(或判定)当前第二设备已经预留的传输资源无法满足第一终端设备待传输数据的时延预算时，第二设备可以触发进行资源重选过程(即重新确定目标资源)。
在一个可能的实现中，前述指示信息中还包括辅助信息，其中，该辅助信息包括物理信道的负载状态信息、待传输数据对应的传输时间信息和待传输数据对应的时延预算中的一种或多种。示例性的，该辅助信息可被第二设备用于确定获取目标传输资源的时间。
其中，物理信道的负载状态信息可以为：若第一终端设备检测传输信道的负载超过过载门限，则确定物理信道的负载状态信息为信道拥塞；若第一终端设备检测信道的负载小于或等于过载门限，则确定该物理信道的负载状态信息为信道畅通。或者物理信道的负载状态信息可以为信道忙碌情况，如为信道忙碌比(channel busy ratio，CBR)。待传输数据对应的传输时间信息可以是以ms/us/时隙/符号为单位的时间值，例如可以由第一终端设备根据待传输数据的数据量信息和信道的传输速率计算得到，例如，可以用待传输数据的数据量信息与信道传输速率的比值表示，或者当第一终端设备采用mode 2方式获取资源时，待传输数据对应的传输时间信息可以为第一终端设备对目标资源确定预留到利用该目标资源进行数据转发(或传输)所用的时间，或从第一终端设备生成数据包到利用预留目标资源开始或完成数据传输所需的时间等。时延预算：待传输数据的数据包的总时延预算，如数据包从第一终端设备传输到第三通信设备之间的时延需求，或待传输数据包的剩余时间信息。
在本实施例中，第二设备可以根据指示信息中辅助信息确定从资源池中获取目标资源的时间。
示例性地，指示信息中包括物理信道的负载状态信息，其中，负载状态信息包括信道拥塞，或信道畅通，或信道忙碌比信息等。其中，信道拥塞时，对应获取目标资源的时间为70ms；信道畅通时，对应获取目标资源的时间为30ms。在这种情况下，若该物理信道的负载状态信息为信道拥塞，则第二设备接收到第一终端设备发送的指示信息后开启计时，当70ms到达时，第二设备从资源池中获取目标资源。若该物理信道的负载状态信息为信道畅通，则第二设备接收到第一终端设备发送的指示信息后开启计时，当30ms到达时，第二终端从资源池中获取目标资源。
示例性地，指示信息中包括待传输数据对应的传输时间信息。假设开发人员通过实验数据测算得到第二设备接收指示消息后从资源池中获取目标资源的时长为20ms，第一终端设备向第二设备发送指示信息，该指示信息包括的待传输数据对应的传输时间信息为100ms，则第二设备可以在接收到第一终端设备发送的指示信息后开启计时，当80ms到达 时，第二设备从资源池中获取目标资源。
示例性地，指示信息中包括时延预算。假设开发人员通过实验数据测算得到第二设备接收指示消息后从资源池中获取目标资源的时长为20ms，第一终端设备向第二设备发送指示信息，该指示信息包括的时延预算为80ms，则第二设备可以在接收到第一终端设备发送的指示信息后，至少在60ms以内，第二设备需要从资源池中获取目标资源。
1105、第二设备接收第一终端设备发送的待传输数据。
第一终端设备向第二设备发送指示消息后，则第一终端设备向第二设备发送待传输数据。
1106、第二设备利用该目标资源向第三通信设备(另一个远端设备)传输待传输数据(即第二设备从侧行链路中接收到的数据)。
第二终端在获取到目标资源和待传输数据之后，利用该目标资源向第三通信设备(网络设备)传输带传输数据。
可见，通过实施例图11所描述的资源调度方法，当第三通信设备为远端设备(第三终端设备)时，由第二设备根据第一终端设备发送的第一信息确定第一配置消息。第一终端设备根据该第一配置消息确定向第二设备发送指示信息，第二设备根据该指示信息中待传输数据的数据量信息从资源池中获取目标资源，进而利用该目标资源向第三通信设备传输待传输数据，降低了中继设备(第二设备)转发数据时的中继延时。
