Description

SR配置的确定方法、装置及存储介质 技术领域
本公开实施例涉及通信技术领域，特别涉及一种SR(Schedule Request，调度请求)配置的确定方法、装置及存储介质。
背景技术
在5G NR(New Radio，新空口)系统中，决定引入多SR配置，也即可以为终端提供多个SR配置，并且使用哪个SR配置取决于触发SR的逻辑信道(logical channel)。
在Uu接口上，基站通过向终端发送RRC(Radio Resource Control，无线资源控制)连接重配置消息，其中携带逻辑信道与SR配置之间的对应关系，以此向终端指示各个逻辑信道对应的SR配置。终端在需要使用某一逻辑信道向基站发送数据时，如果触发SR，则可以根据该逻辑信道对应的SR配置向基站发送SR。
对于终端和终端之间建立的用于传输侧链路(sidelink)数据流的逻辑信道，由于侧链路数据流与逻辑信道之间的映射关系是由终端自己决定的，基站无法获知各个逻辑信道所用于传输的侧链路数据流的相关信息，从而导致基站在确定逻辑信道的SR配置时，不够合理准确。

如图2所示，在5G NR系统中，AS(Access Stratum，接入层)最小的数据传输粒度是QoS流(QoS flow)。QoS流是PDU(Protocol Data Unit，协议 数据单元)会话(session)中最精细的QoS区分粒度，这就是说两个PDU会话的区别就在于它们的QoS流不一样(具体一般就是QoS流的TFT(Traffic Flow Template，业务流模板)参数不同)。在5G NR系统中一个QoS流的标识信息采用QFI(QoS Flow ID)表示，用于标识一条QoS流。PDU会话中具有相同QFI的用户平面数据会获得相同的转发处理(如相同的调度、相同的准入门限等)。QFI在一个PDU会话内要唯一，也就是说一个PDU会话可以有多条(如最多64条)QoS流，但每条QoS流的QFI都是不同的(取值范围0～63)，终端的两条PDU会话的QFI是可能会重复的。QFI可以动态配置或等于5QI(5-Generation QoS Indicator，5G服务质量指示)。AS收到QoS流后，需要完成QoS流到逻辑信道的映射，可以将一个或多个QoS流映射到一个逻辑信道上。在Uu接口上，这个映射关系是由基站控制的。
另外，如图3所示，终端13和终端13(例如车载设备与其它设备(如其它车载设备、手机、RSU(Road Side Unit，路侧单元)等))之间可以通过直连通信接口(如PC5接口)互相通信，相应地，该基于直连通信接口建立的通信链路可以称为直连链路或侧链路(sidelink)。与基于Uu接口通信相比，基于直连通信接口通信具有时延短、开销小等特点，适合用于地理位置接近的两个终端(如车载设备和地理位置接近的其它周边设备)之间的通信。侧链路上最小的数据传输粒度也是QoS流。侧链路上的QoS流的QoS通过VQI(Vehicle QoS Indicator，车辆服务质量指示)来指示，VQI为一个数值，每个数值指示了一套侧链路上的QoS流的服务质量，包括速率、时延、可靠性和传输距离等信息。
本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
在本公开实施例中，针对背景技术中提及的技术问题，通过向基站提供侧链路上传输的QoS流的QoS参数，使得基站能够根据该QoS流的QoS参数，合理、准确地确定出用于传输该QoS流的逻辑信道的SR配置。
下面，通过几个示例性实施例对本公开技术方案进行介绍说明。
图4是根据一示例性实施例示出的一种SR配置的确定方法的流程图。该方法可应用于图1所示的网络架构中。该方法可以包括如下几个步骤 (401～404)。
在步骤401中，终端向基站发送侧链路信息，该侧链路信息包括用于传输第一侧链路数据流的第一逻辑信道对应的QoS参数。
第一侧链路数据流可以是任意一个通过侧链路传输的QoS流。在本公开实施例中，第一侧链路数据流和第一逻辑信道之间存在映射关系，也即由第一逻辑信道来传输该第一侧链路数据流。第一逻辑信道可以是任意一个侧链路逻辑信道。另外，第一侧链路数据流和第一逻辑信道之间的映射关系，可以由终端配置，也可以由基站配置。
第一逻辑信道上可以仅映射一个侧链路数据流，如第一侧链路数据流；或者，第一逻辑信道上也可以映射多个侧链路数据流，如包括第一侧链路数据流和至少一个其它侧链路数据流。
QoS参数用于指示第一侧链路数据流的QoS要求，如包括对速率、时延、可靠性和传输距离等的要求。QoS参数可以采用VQI来表示。
在本公开实施例中，通过终端向基站发送侧链路信息，由于该侧链路信息中包括了第一逻辑信道对应的QoS参数，使得基站能够获知该第一逻辑信道所用于传输的QoS流的QoS要求。
另外，侧链路信息可以通过侧链路终端信息(SidelinkUEInformation)发送给基站，也可以通过其它消息发送给基站，本公开实施例对此不作限定。
在步骤402中，基站根据侧链路信息生成SR配置信息，该SR配置信息用于指示第一逻辑信道的SR配置。
基站在获取到第一逻辑信道上传输的第一侧链路数据流的QoS参数之后，根据该QoS参数为该第一逻辑信道配置相应的SR配置。可选地，SR配置包括但不限于以下至少一项：SR禁止定时器、SR最大传输次数、可用于SR发送的时频资源位置。
另外，基站可以在SR配置信息中显性地指示第一逻辑信道的SR配置，例如SR配置信息中包括第一逻辑信道的标识信息与第一逻辑信道的SR配置之间的对应关系；或者，基站也可以在SR配置信息中隐性地指示第一逻辑信道的SR配置，例如SR配置信息中并不直接包括第一逻辑信道的标识信息与第一逻辑信道的SR配置之间的对应关系，而是包括其它信息，终端根据该其它信息确定出第一逻辑信道的SR配置。有关SR配置信息中包括的具体内容，可以有多种可能的实现方式，具体参见下文实施例中的介绍说明。
在步骤403中，基站向终端发送SR配置信息。
可选地，SR配置信息通过RRC连接重配置消息(RRCConnectionReconfiguration消息)发送给终端，也可以通过其它消息发送给终端，本公开实施例对此不作限定。
在步骤404中，终端根据SR配置信息，确定第一逻辑信道的SR配置。
终端在接收到SR配置信息之后，读取该SR配置信息中包含的内容，据此确定出第一逻辑信道的SR配置。
另外，当逻辑信道中的侧链路数据流的QoS要求发生变化时，终端可以重复执行上述步骤401～404的流程，对逻辑信道的SR配置进行更新，以适应新的QoS要求。
综上所述，本公开实施例提供的技术方案中，通过向基站提供侧链路上传输的QoS流的QoS参数，使得基站能够根据该QoS流的QoS参数，合理、准确地确定出用于传输该QoS流的逻辑信道的SR配置。
在基于图4实施例提供的一个可选实施例中，如图5所示，该方法可以包括如下几个步骤(501～504)。
在步骤501中，终端向基站发送侧链路信息，该侧链路信息包括第一侧链路数据流的VQI。
在本实施例中，侧链路信息包括终端需要传输的至少一个侧链路数据流的VQI，该至少一个侧链路数据流包括第一侧链路数据流。可选地，侧链路信息包括终端需要传输的所有侧链路数据流的VQI。
例如，终端需要传输的侧链路数据流有4个QoS流，这4个QoS流的标识信息(即QFI)分别为1、2、3和4。并且，假设这4个QoS流的VQI分别为1、2、3和4，则终端向基站发送的侧链路信息包括一个VQI列表，该VQI列表中包含终端需要传输的所有QoS流的VQI，也即该VQI列表中包含1、2、3和4共4个VQI。
在本实施例中，侧链路数据流和逻辑信道之间的映射关系，由终端配置。例如，终端配置QFI为1和2的QoS流映射到逻辑信道1，QFI为3的QoS流映射到逻辑信道2，QFI为4的QoS流映射到逻辑信道3。另外，终端可以将具有相同或类似QoS要求的QoS流映射到同一逻辑信道上。
在一种可能的实现方式中，终端先完成侧链路数据流到逻辑信道的映射， 然后终端向基站发送侧链路终端信息，其中携带所有逻辑信道中侧链路数据流的VQI。
在步骤502中，基站根据侧链路信息生成SR配置信息，该SR配置信息包括第一侧链路数据流的VQI与SR配置之间的对应关系。
基站在接收到侧链路信息之后，根据该侧链路信息中包含的VQI列表，为该VQI列表中的每一个VQI配置对应的SR配置。在本公开实施例中，对基站为VQI配置对应的SR配置的具体方式不作限定，例如基站可以为不同的VQI配置不同的SR配置，也可以为多个VQI(如相近的VQI)配置相同的SR配置，本公开实施例对此不作限定。
在步骤503中，基站向终端发送SR配置信息。
可选地，基站向终端发送RRC连接重配置消息，其中携带至少一组SR配置，每一组SR配置与一个VQI列表相对应。
示例性地，RRC连接重配置消息中携带SR参数A、SR参数B和SR参数C，其中SR参数A对应的VQI为1，SR参数B对应的VQI为2，SR参数C对应的VQI为3和4。
在步骤504中，终端根据SR配置信息，确定第一逻辑信道的SR配置。
终端在接收到SR配置信息之后，根据该SR配置信息中包含的第一侧链路数据流的VQI与SR配置之间的对应关系，以及第一侧链路数据流与第一逻辑信道之间的映射关系，将该第一侧链路数据流的VQI对应的SR配置，确定为第一逻辑信道的SR配置。结合上述示例，由于逻辑信道2上映射QFI为3的QoS流，而该QFI为3的QoS流对应的VQI为3，对应SR参数C，因此终端将逻辑信道2对应的SR参数设定为C。
可选地，若第一逻辑信道除了用于传输第一侧链路数据流之外，还用于传输至少一个其它侧链路数据流，则终端根据SR配置信息中包括的第一侧链路数据流的VQI与SR配置之间的对应关系，以及其它侧链路数据流的VQI与SR配置之间的对应关系，选择VQI最大值对应的SR配置确定为第一逻辑信道的SR配置。结合上述示例，由于逻辑信道1上映射QFI为1和2的QoS流，而该QFI为1的QoS流对应的VQI为1，对应SR参数A，QFI为2的QoS流对应的VQI为2，对应SR参数B，因此终端选择VQI最大值对应的SR配置，也即VQI 2对应的SR参数B确定为逻辑信道1的SR配置。通过上述方式，当某一逻辑信道映射有多个不同QoS要求的QoS流时，通过选择VQI最 大值对应的SR配置，作为该逻辑信道的SR配置，能够满足最高的QoS要求，确保该逻辑信道的SR配置的可靠性。
另外，当逻辑信道中的侧链路数据流的QoS要求发生变化时，终端可以重复执行上述步骤501～504的流程，对逻辑信道的SR配置进行更新，以适应新的QoS要求。
在基于图4实施例提供的另一个可选实施例中，如图6所示，该方法可以包括如下几个步骤(601～604)。
在步骤601中，终端向基站发送侧链路信息，该侧链路信息包括第一逻辑信道的标识信息与第一侧链路数据流的VQI之间的对应关系。
在本实施例中，侧链路信息包括VQI和逻辑信道之间的对应关系。例如，侧链路信息包括终端创建的用于传输侧链路数据流的至少一个逻辑信道的标识信息，该至少一个逻辑信道包括第一逻辑信道；并且，侧链路信息还包括每个逻辑信道对应的VQI，也即每个逻辑信道映射的侧链路数据流的VQI。
例如，终端需要传输的侧链路数据流有4个QoS流，这4个QoS流的标识信息(即QFI)分别为1、2、3和4。并且，假设这4个QoS流的VQI分别为1、2、3和4。在本实施例中，侧链路数据流和逻辑信道之间的映射关系，由终端配置。例如，终端配置QFI为1和2的QoS流映射到逻辑信道1，QFI为3的QoS流映射到逻辑信道2，QFI为4的QoS流映射到逻辑信道3。另外，终端可以将具有相同或类似QoS要求的QoS流映射到同一逻辑信道上。这样，终端向基站发送的侧链路信息包括逻辑信道1与VQI 1和VQI 2之间的对应关系、逻辑信道2与VQI 3之间的对应关系，以及逻辑信道3与VQI 4之间的对应关系。
在步骤602中，基站根据侧链路信息生成SR配置信息，该SR配置信息包括第一逻辑信道的标识信息与第一逻辑信道的SR配置之间的对应关系。
基站在接收到侧链路信息之后，根据该侧链路信息中包含的逻辑信道与VQI之间的对应关系，为各个逻辑信道配置对应的SR配置。在本公开实施例中，对基站为逻辑信道配置对应的SR配置的具体方式不作限定，例如当某一逻辑信道对应多个VQI时，基站根据该多个VQI中的VQI最大值确定该逻辑信道的SR配置，从而满足最高的QoS要求，确保该逻辑信道的SR配置的可靠性。另外，基站可以为不同的逻辑信道配置不同的SR配置，也可以为不同 的逻辑信道配置相同的SR配置，本公开实施例对此不作限定。
仍然结合上述例子，基站生成的SR配置信息可以包括：逻辑信道1与SR参数B之间的对应关系，逻辑信道2和3与SR参数C之间的对应关系。
在步骤603中，基站向终端发送SR配置信息。
SR配置信息可以通过RRC连接重配置消息发送给终端，也可以通过其它消息发送给终端，本公开实施例对此不作限定。
在步骤604中，终端根据SR配置信息，确定第一逻辑信道的SR配置。
终端在接收到SR配置信息之后，读取该SR配置信息中包含的逻辑信道与SR配置之间的对应关系，以此确定出各个逻辑信道的SR配置。
仍然结合上述例子，终端将逻辑信道1对应的SR参数设定为B，将逻辑信道2和3对应的SR参数均设定为C。
另外，当逻辑信道中的侧链路数据流的QoS要求发生变化时，终端可以重复执行上述步骤601～604的流程，对逻辑信道的SR配置进行更新，以适应新的QoS要求。
在基于图4实施例提供的另一个可选实施例中，如图7所示，该方法可以包括如下几个步骤(701～704)。
在步骤701中，终端向基站发送侧链路信息，该侧链路信息包括第一侧链路数据流的标识信息与第一侧链路数据流的VQI之间的对应关系。
在本实施例中，侧链路信息包括侧链路数据流和VQI之间的对应关系。例如，侧链路信息包括终端需要传输的至少一个侧链路数据流的标识信息与VQI之间的对应关系，该至少一个侧链路数据流包括第一侧链路数据流。可选地，侧链路信息包括终端需要传输的所有侧链路数据流的标识信息与VQI之间的对应关系。
例如，终端需要传输的侧链路数据流有4个QoS流，这4个QoS流的标识信息(即QFI)分别为1、2、3和4，则终端向基站发送的侧链路信息包括一个QFI列表，该QFI列表中包含终端需要传输的所有QoS流的QFI，也即该QFI列表中包含1、2、3和4共4个QFI；并且，终端在侧链路信息中指示上述4个QFI各自对应的VQI分别为1、2、3和4。
在步骤702中，基站根据侧链路信息生成SR配置信息，该SR配置信息包括第一侧链路数据流的标识信息与第一逻辑信道的标识信息之间的对应关 系，以及第一逻辑信道的标识信息与第一逻辑信道的SR配置之间的对应关系。
在本实施例中，侧链路数据流和逻辑信道之间的映射关系，由基站配置。例如，基站配置QFI为1和2的QoS流映射到逻辑信道1，QFI为3的QoS流映射到逻辑信道2，QFI为4的QoS流映射到逻辑信道3。另外，基站可以将具有相同或类似QoS要求的QoS流映射到同一逻辑信道上。
另外，基站在配置完成侧链路数据流和逻辑信道之间的映射关系之后，根据各个逻辑信道对应的侧链路数据流的QoS要求，为各个逻辑信道配置对应的SR配置。在本公开实施例中，对基站为逻辑信道配置对应的SR配置的具体方式不作限定，例如当某一逻辑信道对应多个VQI时，基站根据该多个VQI中的VQI最大值确定该逻辑信道的SR配置，从而满足最高的QoS要求，确保该逻辑信道的SR配置的可靠性。另外，基站可以为不同的逻辑信道配置不同的SR配置，也可以为不同的逻辑信道配置相同的SR配置，本公开实施例对此不作限定。
仍然结合上述例子，基站生成的SR配置信息可以包括：QFI 1和QFI 2与逻辑信道1之间的对应关系，QFI 3与逻辑信道2之间的对应关系，以及QFI4与逻辑信道3之间的对应关系；另外，该SR配置信息还包括逻辑信道1与SR参数B之间的对应关系，以及逻辑信道2和3与SR参数C之间的对应关系。
在步骤703中，基站向终端发送SR配置信息。
SR配置信息可以通过RRC连接重配置消息发送给终端，也可以通过其它消息发送给终端，本公开实施例对此不作限定。
在步骤704中，终端根据SR配置信息，确定第一逻辑信道的SR配置。
终端在接收到SR配置信息之后，读取该SR配置信息中包含的侧链路数据流与逻辑信道之间的对应关系，以及逻辑信道与SR配置之间的对应关系，以此完成侧链路数据流与逻辑信道之间的映射，以及确定出各个逻辑信道的SR配置。
仍然结合上述例子，终端将QFI为1和2的QoS流映射到逻辑信道1，QFI为3的QoS流映射到逻辑信道2，QFI为4的QoS流映射到逻辑信道3。另外，终端将逻辑信道1对应的SR参数设定为B，将逻辑信道2和3对应的SR参数均设定为C。
另外，当逻辑信道中的侧链路数据流的QoS要求发生变化时，终端可以重 复执行上述步骤701～704的流程，对逻辑信道的SR配置进行更新，以适应新的QoS要求。
在上述图5、图6和图7实施例中，提供了为侧链路逻辑信道配置SR配置的3种不同实现方式，这3种实现方式均可以实现向基站提供侧链路上传输的QoS流的QoS参数，使得基站能够根据该QoS流的QoS参数，合理、准确地确定出用于传输该QoS流的逻辑信道的SR配置。在这3种实现方式中，基站的控制能力逐渐提升，相应地终端和基站之间交互的信令也会增多。在实际应用中，可以结合实际需求，选择合适的实现方式。
还需要说明的一点是，在上述方法实施例中，仅从终端和基站交互的角度对本公开技术方案进行了介绍说明。上述有关终端执行的步骤，可以单独实现成为终端侧的SR配置的确定方法；上述有关基站执行的步骤，可以单独实现成为基站侧的SR配置的确定方法。

图10是根据一示例性实施例示出的一种终端的结构示意图。
