下面对本申请实施例中所涉及到的名词进行介绍说明：
侧行链路(Sidelink，SL)：是针对终端和终端之间直接通信定义的，即终端和终端之间不通过网络设备转发而直接通信的链路。通常，一个侧行链路可以包括一个或者多个侧行链路逻辑信道组(Logical Channel Group，LCG)，一个侧行链路逻辑信道组可以包括一个或者多个侧行链路逻辑信道(Logical Channel，LCH)。
侧行链路资源：是指终端与终端之间直接进行信息传输时所使用的时频资源，还可以指终端与终端之间直接进行信息传输时所使用的空域资源等。
Uu缓存状态报告(Buffer Status Report，BSR)：是终端发送给接入网设备的一种信息，可用于请求接入网设备为终端分配上行链路资源。其中，Uu BSR中通常可以包括该上行链路上需要传输的数据量。接入网设备可以根据该数据量分配对应大小的上行链路资源。
侧行链路缓存状态报告(Sidelink Buffer Status Report，SL BSR)：是终端发送给接入网设备的一种信息，可用于请求接入网设备为终端分配侧行链路资源。其中，侧行链路的BSR中通常可以包括该侧行链路上需要传输的数据量。接入网设备可以根据该数据量分配对应大小的侧行链路资源。
调度请求(Scheduling Request，SR)：是终端发送给接入网设备的另一种信息，可用于请求接入网设备为终端分配用于传输BSR的上行资源。
在本申请实施例中，V2X业务在侧行链路对应的侧行链路资源上传输，Uu业务在Uu链路对应的Uu资源上传输。在V2X通信中，该终端获取侧行链路资源可以通过如下方式：
方式一：终端基于调度模式获取侧行链路资源。即当进行V2X通信的连接态终端需要在侧行链路上向另一个终端传输信息时，该终端需要首先向接入网设备发送侧行链路缓存状态报告(Sidelink Buffer Status Report，SL BSR)。该SL BSR用于报告该终端当前需要在侧行链路上传输的数据量，以便接入网设备根据该数据量分配适当大小的侧行链路资源。通常情况下，终端可以在上行资源上向网络设备发送SL BSR。如果该终端当前没有上行资源上报SL BSR，则可能触发调度请求(Scheduling Request，SR)，SR用于请求接入网设备为该终端分配发送SL BSR的上行资源。当接入网设备接收到该SR后，根据调度结果，为该终端分配上行资源授权，用于该终端发送SL BSR。
方式二：终端基于自主模式获取侧行链路资源。即当进行侧行链路通信的终端需要在侧行链路上向另一个或多个终端传输信息时，该终端可以在接入网设备配置或预配置的资源池中自主选择资源，以利用自主选择的侧行链路资源向另一个或多个终端传输信息。其中，接入网设备配置的资源池可以通过系统信息来配置，也可以在接收到该终端要进行侧行链路通信的请求后通过专用信令来配置，或者采用预配置的方式。
方式三：终端基于调度及自主联合模式获取侧行链路资源。即当进行侧行链路通信的终端需要在侧行链路上向至少一个终端传输信息时，该终端可以同时采样上述方式一和上述方式二所提供的方法获取侧行链路资源。示例性地，终端通过调度模式请求用于业务1的资源，用自主模式为业务2选择资源。
需要说明的是，在本申请实施例中，一个终端的侧行链路可以用于传输一个或者多个业务的数据，且一个业务的数据可以在一个或者多个侧行链路逻辑信道上传输。基于此，本申请实施例中的调度及自主联合模式可以是终端粒度的，也可以是业务粒度的，或者是侧行链路逻辑信道粒度的，或者是侧行链路逻辑信道组粒度的。终端粒度的调度及自主联合模式可以是以该终端为单位进行描述的，若该终端支持调度及自主联合模式，则该终端的侧行链路资源可以通过调度模式和/或自主模式获取，即可以通过调度模式获取，或者通过自主模式获取，或者同时通过调度模式和自主模式获取。业务粒度的调度及自主联合模式可以是以业务为单位进行描述的，若该终端的侧行链路上某一业务支持调度及自主联合模式，则用于传输该业务既可以利用调度模式的资源进行传输，也可以用资源模式选择的资源进行传输。侧行链路逻辑信道粒度的调度及自主联合模式可以是以侧行链路逻辑信道为单位进行描述的，若该终端的某一侧行链路逻辑信道支持调度及自主联合模式，则该侧行链路逻辑信道中的数据既可以利用调度模式分配的资源，也可以利用自主模式选择得到的资源。侧行链路逻辑信道组粒度的调度及自主联合模式可以是以侧行链路逻辑信道组为单位进行描述的，若该终端的某一侧行链路逻辑信道组支持调度及自主联合模式，则该侧行链路逻辑信道组中的数据既可以利用调度模式分配的资源，也可以利用自主模式选择得到的资源。
在本申请实施例中，若终端或者该终端的侧行链路业务工作于自主模式，通过模式重配可以将该终端或者该终端的侧行链路业务的工作模式从自主模式切换为调度模式或者调度及自主联合模式；若终端或者该终端的侧行链路业务工作于调度模式，通过模式重配可以将该终端或者该终端的侧行链路业务的工作模式从调度模式切换为自主模式或者调度及自主联合模式；若终端或者该终端的侧行链路业务工作于调度及自主联合模式，通过模式重配可以将该终端或者该终端的侧行链路业务的工作模式从调度及自主联合模式切换为自主模式或者调度模式。
其中，当该终端或者该终端的侧行链路业务的工作模式从自主模式切换为调度模式或者调度及自主联合模式、从调度模式切换为自主模式、或者从调度及自主联合模式切换为自主模式时，该终端均可以按照上述方式一、方式二或方式三所提供的方式，获取侧行链路资源。当该终端或者该终端的侧行链路业务的工作模式从调度模式切换为调度及自主联合模式、或者从调度及自主联合模式切换为调度模式时，该终端可以通过下文中图2至图6任一图示所提供的方法来获取侧行链路资源。
图2为本申请实施例提供的一种资源调度方法的流程示意图，该方法可应用于图 1所示的通信系统。参见图2，该方法包括以下几个步骤。
S201：终端满足第一触发条件，该终端触发资源调度请求，该资源调度请求用于请求接入网设备为该终端分配上行资源或者侧行链路资源。
在本申请实施例中，第一触发条件包括：该终端或者该终端的侧行链路业务的工作模式从第一模式切换为第二模式。其中，第一模式和第二模式不同，且第一模式和第二模式为以下模式中的一种：调度模式，调度及自主联合模式。
其中，该终端或者该终端的侧行链路业务在模式切换之前工作于第一模式，该接入网设备可以通过模式重配将该终端或者该终端的侧行链路业务的工作模式从第一模式切换为第二模式，具体可以为：将该终端或者该终端的侧行链路业务的工作模式从调度模式切换为调度及自主联合模式，或者从调度及自主联合模式切换为调度模式。
另外，侧行链路业务包括以下任一个或多个：侧行链路服务质量流(Sidelink QoS flow)、侧行链路逻辑信道(Sidelink Logical Channel，Sidelink LCH)、侧行链路数据无线承载(Sidelink Data Radio Bear，Sidelink DRB)、侧行链路逻辑信道组(Sidelink Logical Channel Group，Sidelink LCG)、侧行链路业务目标标识、侧行链路分组数据单元会话(Sidelink Packet Data Unit，Sidelink PDU)。该业务目标标识可以为destination ID，业务目标标识通常指示某种特定的业务消息或业务数据的类型、或者指示接收终端或接收终端组。
具体的，当第一触发条件仅包括该终端或者该终端的侧行链路业务的工作模式从第一模式切换为第二模式时，该终端可以触发资源调度请求。或者，当第一触发条件除了包括该终端或者该终端的侧行链路业务的工作模式从第一模式切换为第二模式之外，还同时包括其他条件时，该终端也可以触发资源调度请求，具体参见如下第一种至第三种所述的情况。
第一种：第一触发条件具体可以为：该终端或者该终端的侧行链路业务的工作模式从第一模式切换为第二模式，且该终端没有新数据。其中，新数据可以是指该终端或者该终端的侧行链路业务的工作模式从第一模式切换为第二模式之后该终端产生的需要在侧行链路上传输的数据(Data)。该终端没有新数据可以理解为：该终端没有产生需要在侧行链路上传输的新数据，或者，模式重配前后该终端的可用数据量没有增加。该可用数据可以是指该终端产生的，需要在侧行链路上传输的所有数据，即包括工作在第一模式下时该终端产生的需要在侧行链路上传输的数据，也包括从第一模式切换为第二模式后该终端产生的需要在侧行链路上传输的新数据。该可用数据也可以称为有效(available)数据。
第二种：第一触发条件具体可以为：该终端或者该终端的侧行链路业务的工作模式从第一模式切换为第二模式，且该终端有对应第一侧行链路逻辑信道的新数据，第一侧行链路逻辑信道的优先级低于或等于第二侧行链路逻辑信道的优先级，第二侧行链路逻辑信道为该终端的可用数据中第一数据对应的侧行链路逻辑信道。
其中，该终端有对应第一侧行链路逻辑信道的新数据可以理解为：该终端产生了需要在第一侧行链路信道上传输的新数据。另外，该可用数据可以是指该终端产生的，需要在侧行链路上传输的所有数据，即包括工作在第一模式下时该终端产生的需要在侧行链路上传输的数据，也包括从第一模式切换为第二模式后该终端产生的需要在侧 行链路上传输的新数据。该可用数据也可以称为有效(available)数据。
在一种可能的实施例中，第一数据可以为该可用数据中除该新数据之外的其他数据。比如，该可用数据包括5个数据包，分别表示为D1、D2、D3、D4和D5，该新数据对应的数据包为D1，则除该新数据之外的其他数据对应的数据包为D2、D3、D4和D5。
在另一种可能的实施例中，第一数据可以为该可用数据中除该新数据之外且与该新数据对应同一目标标识的其他数据。其中，该目标标识可以是指目的地的标识，比如，该目标标识可以是接收终端的层2目标标识，或者一组接收终端共用的群组特定的层2目标标识，或者服务特定的层2目标标识。其中，一个目标标识可以对应多个SL LCH，每个SL LCH的缓存器中可能有数据。
或者，第一侧行链路逻辑信道的优先级低于或等于与该侧行链路逻辑信道同属于同一目标标识的所有逻辑信道组中的有可用数据的侧行链路逻辑信道的优先级；或者，第一侧行链路逻辑信道的优先级低于或者等于与该侧行链路逻辑信道同属于同一侧行链路逻辑信道组的其他有可用数据的侧行链路逻辑信道的优先级。
第三种：第一触发条件具体为：该终端或者该终端的侧行链路业务的工作模式从第一模式切换为第二模式，且该终端的可用数据对应的侧行链路逻辑信道中存在支持调度模式的侧行链路逻辑信道，或者该终端的可用数据对应的业务支持调度模式。
其中，该可用数据可以对应多个侧行链路逻辑信道。所述存在支持调度模式的侧行链路逻辑信道，可以是指该多个侧行链路逻辑信道中存在至少一个侧行链路逻辑信道支持调度模式，即该至少一个侧行链路逻辑信道中的数据可以复用(即装载)在通过调度模式获取的侧行链路资源上，或者该至少一个侧行链路逻辑信道可以触发侧行链路缓存状态报告。该可用数据对应的业务支持调度模式，可以是指该多个侧行链路逻辑信道中用于传输该业务的数据的一个或者多个侧行链路逻辑信道对应的资源可以通过调度模式的方式获取。
可选的，在第三种情况下，第一触发条件还可以包括上述第一种或第二种所述的部分条件，具体的：第一触发条件还包括该终端没有新数据；或者，第一触发条件还包括该终端有对应第一侧行链路逻辑信道的新数据，第一侧行链路逻辑信道的优先级低于或等于第二侧行链路逻辑信道的优先级，第二侧行链路逻辑信道为该终端的可用数据中第一数据对应的侧行链路逻辑信道。
S202a：该终端向该接入网设备发送该资源调度请求。其中，当该终端有可用于发送该资源调度请求的资源时，该终端向该接入网设备发送该资源调度请求。
S202b：该接入网设备向该终端发送资源指示信息，该资源指示信息用于指示上行资源或者侧行链路资源。
当该接入网设备接收到该资源调度请求时，该接入网设备可以根据该资源调度请求，为该终端分配上行资源或者侧行链路资源，并通过该资源指示信息将该上行资源或者该侧行链路资源通知给该终端。
在本申请实施例中，该终端向接入网设备触发的资源调度请求可以为侧行链路缓存状态报告SL BSR或者调度请求SR两种不同的情况，下面分别对这两种情况进行介绍说明。
第I种、如图3所示，该资源调度请求为SL BSR，该SL BSR用于请求该接入网设备为该终端分配侧行链路资源。相应的，S201具体可以为：该终端满足第一触发条件，该终端触发SL BSR；S202a具体可以为：当有可用于发送该SL BSR的上行资源时，向接入网设备发送该SL BSR；S202b具体可以为：该接入网设备向该终端发送资源指示信息，该资源指示信息用于指示侧行链路资源。
其中，该SL BSR可以由可用数据对应的多个侧行链路逻辑信道中满足第一预设条件的第三侧行链路逻辑信道触发，即当该终端满足第一触发条件(比如，该终端的工作模式从第一模式切换为第二模式)时，该终端触发SL BSR，该SL BSR是由第三侧行链路逻辑信道触发的。
可选的，第三侧行链路逻辑信道可以为该多个侧行链路逻辑信道中支持调度模式的逻辑信道中优先级最高的侧行链路逻辑信道。比如，该多个侧行链路逻辑信道包括三个侧行链路逻辑信道，分别表示为LCH1、LCH2和LCH3，LCH1和LCH2均支持调度模式，且LCH1的优先级高于LCH2的优先级，则第三侧行链路逻辑信道即为LCH1。
或者，第三侧行链路逻辑信道可以为该多个侧行链路逻辑信道中工作模式从第一模式切换为第二模式的侧行链路逻辑信道。比如，该多个侧行链路逻辑信道包括三个侧行链路逻辑信道，分别表示为LCH1、LCH2和LCH3，LCH1和LCH2的工作模式从第一模式切换为第二模式，则第三侧行链路逻辑信道可以为LCH1或者LCH2。
或者，第三侧行链路逻辑信道可以为该多个侧行链路逻辑信道中工作模式从第一模式切换为第二模式的侧行链路逻辑信道中优先级最高的侧行链路逻辑信道。比如，该多个侧行链路逻辑信道包括三个侧行链路逻辑信道，分别表示为LCH1、LCH2和LCH3，LCH1、LCH2和LCH3的工作模式从第一模式切换为第二模式，且LCH1的优先级最高，则第三侧行链路逻辑信道可以为LCH1。
或者，第三侧行链路逻辑信道可以为该多个侧行链路逻辑信道中支持调度模式的侧行链路逻辑信道。比如，该多个侧行链路逻辑信道包括三个侧行链路逻辑信道，分别表示为LCH1、LCH2和LCH3，LCH1支持调度模式，则第三侧行链路逻辑信道即为LCH1。
另外，该SL BSR的类型可以为常规(regular)SL BSR。在本申请实施例中，当该BSR的类型为常规BSR时，参见图3，在该终端发送资源调度请求之前，该方法还可以包括：S203a-S203c。
S203a：该终端触发第一SR，第一SR用于请求该接入网设备为该终端分配用于发送该BSR的上行资源。
S203b：该终端向该接入网设备发送第一SR。
具体的，当该终端满足第一触发条件，但是该终端没有用于发送该SL BSR的上行资源时，该终端可以触发第一SR，并当SR资源可用时，向该接入网设备发送第一SR，以请求接入网设备分配用于发送该BSR的上行资源，该SR资源是指用于发送第一SR的资源。
S203c：当该接入网设备接收到第一SR时，该接入网设备向该终端发送第一资源指示信息，第一资源指示信息用于指示该上行资源。
当该接入网设备接收到第一SR时，该接入网设备可以为该终端分配用于发送该 SL BSR的上行资源，并通过第一资源指示信息将该上行资源通知给该终端。进而，当该终端接收到第一资源指示信息时，该终端可以通过S201在第一资源指示信息所指示的上行资源向该接入网设备发送该BSR。
第II种、如图4所示，该资源调度请求为第二SR，第二SR用于请求该接入网设备为该终端分配上行资源，该上行资源用于发送SL BSR。
相应的，S201具体可以为：该终端满足第一触发条件，该终端触发第二SR；S202a具体为：当SR资源可用时，该终端向该接入网设备发送第二SR；S202b具体可以为：该接入网设备向该终端发送资源指示信息，该资源指示信息用于指示上行资源。
具体的，当该终端满足第一触发条件时，该终端可以触发第二SR，并在有可用的SR资源时，该终端向该接入网设备发送第二SR。当该接入网设备接收到第二SR时，该接入网设备可以为该终端分别上行资源，并通过该资源指示信息将该上行资源通知给该终端。之后，该终端可以在该上行资源上向该接入网设备发送SL BSR；该接入网设备在接收到该SL BSR时，可以向该终端发送侧行链路资源的指示信息，以使该终端根据该指示信息确定该侧行链路资源。
其中，第二SR可以关联于多个侧行链路逻辑信道中的第四侧行链路逻辑信道，即当该终端满足第一触发条件(比如，该终端的工作模式从第一模式切换为第二模式)时，该终端触发第二SR，该第二SR关联于第四侧行链路逻辑信道，即第二SR采用第四侧行链路逻辑信道所关联的SR配置和SR资源。可选的，第四侧行链路逻辑信道可以为该多个侧行链路逻辑信道中支持调度模式的逻辑信道中且关联有SR配置的优先级最高的侧行链路逻辑信道。比如，该多个侧行链路逻辑信道包括三个且关联有SR配置的侧行链路逻辑信道，分别表示为LCH1、LCH2和LCH3，LCH1和LCH2均支持调度模式，且LCH1的优先级高于LCH2的优先级，则第四侧行链路逻辑信道即为LCH1。
或者，第四侧行链路逻辑信道可以为该多个侧行链路逻辑信道中支持调度模式的优先级最高的侧行链路逻辑信道。比如，该多个侧行链路逻辑信道包括三个侧行链路逻辑信道，分别表示为LCH1、LCH2和LCH3，LCH1和LCH2均支持调度模式，且LCH1的优先级高于LCH2的优先级，则第四侧行链路逻辑信道即为LCH1；若LCH1关联有SR配置，则触发第二SR；若LCH1没有关联SR配置，则发起随机接入。
或者，第四侧行链路逻辑信道可以为该多个侧行链路逻辑信道中工作模式从第一模式切换为第二模式且关联有SR配置的侧行链路逻辑信道。比如，该多个侧行链路逻辑信道包括三个侧行链路逻辑信道，分别表示为LCH1、LCH2和LCH3，LCH1和LCH2的工作模式从第一模式切换为第二模式，则第四侧行链路逻辑信道可以为LCH1或者LCH2。
或者，第四侧行链路逻辑信道可以为该多个侧行链路逻辑信道中工作模式从第一模式切换为第二模式的侧行链路逻辑信道。比如，该多个侧行链路逻辑信道包括三个侧行链路逻辑信道，分别表示为LCH1、LCH2和LCH3，LCH1和LCH2的工作模式从第一模式切换为第二模式，则第四侧行链路逻辑信道可以为LCH1或者LCH2；若第四侧行链路逻辑信道关联有SR配置，则触发第二SR；若第四侧行链路逻辑信道没有关联SR配置，则发起随机接入。
或者，第四侧行链路逻辑信道可以为该多个侧行链路逻辑信道中工作模式从第一模式切换为第二模式的侧行链路逻辑信道中关联有SR配置的优先级最高的侧行链路逻辑信道。比如，该多个侧行链路逻辑信道包括三个关联有SR配置的侧行链路逻辑信道，分别表示为LCH1、LCH2和LCH3，LCH1、LCH2和LCH3的工作模式从第一模式切换为第二模式，且LCH1的优先级最高，则第四侧行链路逻辑信道可以为LCH1。
或者，第四侧行链路逻辑信道可以为该多个侧行链路逻辑信道中工作模式从第一模式切换为第二模式的侧行链路逻辑信道的优先级最高的侧行链路逻辑信道。比如，该多个侧行链路逻辑信道包括三个关联有SR配置的侧行链路逻辑信道，分别表示为LCH1、LCH2和LCH3，LCH1、LCH2和LCH3的工作模式从第一模式切换为第二模式，且LCH1的优先级最高，则第四侧行链路逻辑信道可以为LCH1。若第四侧行链路逻辑信道关联有SR配置，则触发第二SR；若第四侧行链路逻辑信道没有关联SR配置，则发起随机接入。
本申请实施例提供的资源调度方法中，当该终端满足第一触发条件时，该终端触发资源调度请求，并在有可用的上行资源或SR资源时，该终端向该接入网设备发送资源调度请求，即将自身的资源调度需求发送给该接入网设备，该接入网设备可以根据该资源调度请求为该终端合理地分配用于请求侧行链路资源的上行资源或者侧行链路资源，从而解决了该终端在发生模式重配时，如何获取侧行链路资源的问题。此外，该终端在获取该侧行链路资源后，可以通过使用该侧行链路资源传输侧行链路数据，从而减小了该侧行链路上业务的传输时延。
