Description

资源碰撞解决方法、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V2X(Vehicle to Everything，车联网)直连通信场景下的资源碰撞解决方法、装置及存储介质。
背景技术
在V2X技术中，车载设备与其它设备(如其它车载设备、路侧基础设施等)之间可以通过侧链路(sidelink)进行直连通信。直连通信具有时延短、开销小等特点。
LTE(Long Term Evolution，长期演进)V2X技术中的直连通信场景，不支持单播和组播通信，仅支持广播通信。对于5G NR(New Radio，新空口)V2X技术中的直连通信场景，随着新业务需求的出现，需要支持单播和组播通信。由于有了单播和组播的功能，且直连通信场景下的资源分配可以由设备各自独立分配，因此出现资源碰撞的概率也就大大增加。例如，当两个发送设备需要占用相同的资源向同一接收设备发送信息时，就会出现资源碰撞。
目前，解决资源碰撞的主要方法是监听(sensing)，即发送设备在发送信息之前，先监听各个资源块上的接收信号强度，若某一资源块上的接收信号强度高于一个预定义的阈值，则表示该资源块已经被占用，发送设备就不再占用该资源块发送信息，避免出现资源碰撞。
上述方式只能够检测出当前正在被占用的资源块，但未来需要被占用的资源块是否出现资源碰撞则无法被检测出来。比如，第一发送设备已经计划在未来的目标时刻占用目标资源块向接收设备发送信息，而第二发送设备在当前时刻监听时，监听到该目标资源块空闲，所以第二发送设备也计划在目标时刻占用该目标资源块向接收设备发送信息，此时这两个发送设备就会占用同一资源块向同一接收设备发送信息，出现资源碰撞。
因此，上述相关技术提供的方法，仍然无法彻底解决资源碰撞的问题。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施 方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
本公开实施例描述的网络架构以及业务场景是为了更加清楚地说明本公开实施例的技术方案，并不构成对本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
图1示出了本公开实施例可能适用的一种网络架构的示意图。该网络架构可以是一种C-V2X系统的网络架构。其中，C是指蜂窝(Cellular)，C-V2X系统是基于3G、4G或5G等蜂窝网通信系统演进形成的车载无线通信系统。该网络架构可以包括：核心网11、接入网12、终端13和车辆14。
核心网11中包括若干核心网设备。核心网设备的功能主要是提供用户连接、对用户的管理以及对业务完成承载，作为承载网络提供到外部网络的接口。例如，LTE(Long Term Evolution，长期演进)系统的核心网中可以包括MME(Mobility Management Entity，移动管理节点)、S-GW(Serving Gateway，服务网关)、P-GW(PDN Gateway，PDN网关)等设备。5G NR系统的核心网中可以包括AMF(Access and Mobility Management Function，接入和移动性管理功能)实体、UPF(User Plane Function，用户平面功能)实体和SMF(Session Management Function，会话管理功能)实体等设备。
接入网12中包括若干接入网设备120。接入网设备120与核心网设备110之间通过某种空口技术互相通信，例如LTE系统中的S1接口，5G NR系统中的NG接口。接入网设备120可以是基站(Base Station，BS)，所述基站是一种部署在接入网中用以为终端提供无线通信功能的装置。所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE系统中，称为eNodeB或者eNB；在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能会变化。为方便描述，本公开实施例中，上述为终端提供无线通信功能的装置统称为接入网设备。
终端13可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，上面提到的设备统称为终端。接入网设备120与 终端13之间通过某种空口技术互相通信，例如Uu接口。
车辆14可以是自动驾驶车辆，也可以是非自动驾驶车辆。车辆14具备一车载设备，车辆14通过车载设备实现和其它车辆、终端13或者其它设备的通信，例如RSU(Road Side Unit，路侧单元)。该车载设备也可以称为车载终端、车载通信装置或其它名称，本公开实施例对此不作限定。车载设备可以是一集成在车载通信盒(Telematics BOX，T-BOX)里的装置，也可以是一跟车体分离的装置。此外，车载设备可以在车辆14出厂前装配在车辆14中，也可以在车辆14出厂后装配在车辆14中。
车辆14的车载设备与其它设备(如其它车载设备、终端13、RSU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)。此外，车辆14的车载设备与其它设备之间还可以通过接入网12以及核心网11进行中转，即利用原有的蜂窝网络中终端13与接入网设备120之间的通信链路进行通信。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，适合用于车载设备和地理位置接近的其它周边设备之间的通信。
上述图1所示的网络架构可以实现V2X业务场景，上述网络架构中还可以包括RSU、V2X应用服务器、V2X控制功能节点等设备，本公开实施例对此不作限定。另外，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，针对上述V2X业务场景中的直连通信场景，提供了一种资源碰撞解决方法，以解决资源碰撞的问题。
在本公开实施例中，第一设备和第二设备是V2X业务场景中，进行直连通信的两端设备，第一设备和第二设备之间可以通过直连通信接口(如PC5接口)建立侧链路，然后通过该侧链路进行用户面数据和控制面信令的交互。例如，第一设备可以是图1所示网络架构中的车辆14的车载设备，第二设备可以是其它车辆的车载设备，也可以是终端13或者RSU等。又例如，第一设备可以是图1所示网络架构中的终端13，第二设备可以是其它终端，也可以是车辆14的车载设备或者RSU等。在一些实施例中，对于同一设备(如同一车载设备或同一终端)来讲，其在某些场景下可以作为第一设备，在另一些场景下也可以作为第二设备。
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2是根据一示例性实施例示出的一种V2X直连通信场景下的资源碰撞解决方法的流程图。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(201～203)。
在步骤201中，第一设备接收n个第二设备各自发送的资源分配信息，n为大于1的整数。
资源分配信息用于指示第二设备为其与第一设备之间传输的直连通信信息所分配的资源。
在一个示例中，直连通信信息包括第二设备通过侧链路向第一设备发送的信息。例如，第二设备在需要通过侧链路向第一设备发送信息之前，第二设备先为该信息分配资源，然后向第一设备发送资源分配信息，以此告知第一设备，该第二设备计划占用哪个资源向第一设备发送信息。
在另一个示例中，直连通信信息包括第一设备通过侧链路向第二设备发送的信息。例如，第一设备在需要通过侧链路向第二设备发送信息之前，第二设备先为该信息分配资源，然后向第一设备发送资源分配信息，以此告知第一设备，该第二设备为第一设备分配的用于发送上述信息的资源。
在本公开实施例中，上述为直连通信信息所分配的资源是指在发送该直连通信信息时所使用的无线资源。可选地，该资源包括以下任意一种或多种的组合：时域资源、频域资源、码域资源、空域资源。空域资源可以是指波束方向。
另外，上述直连通信信息可以包括控制面信令和/或用户面数据。
可选地，资源分配信息中包括发送端设备的标识信息和/或接收端设备的标识信息。其中，发送端设备是指发送该资源分配信息的设备，也即第二设备；接收端设备是指接收该资源分配信息的设备，也即第一设备。
在本公开实施例中，设备的标识信息是用于唯一标识该设备的信息，不同的设备具有不同的标识信息。例如，第一设备的标识信息用于唯一标识该第一设备，第二设备的标识信息用于唯一标识该第二设备，第一设备的标识信息与第二设备的标识信息不同。
可选地，第一设备在接收到资源分配信息时，检测该资源分配信息中是否包括第一设备的标识信息；如果该资源分配信息中包括第一设备的标识信息，则第一设备确认该资源分配信息是发送给自己的，第一设备对该资源分配信息执行后续处理；如果该资源分配信息中不包括第一设备的标识信息，则第一设 备确认该资源分配信息并不是发送给自己的，第一设备不对该资源分配信息执行后续处理，如丢弃该资源分配信息。另外，第一设备在接收到资源分配信息之后，还可以根据该资源分配信息中携带的发送端设备的标识信息，确定该资源分配信息是由哪一个发送端设备发送的。
可选地，资源分配信息以SCI(Sidelink Control Information，侧链路控制信息)的形式发送。
在步骤202中，第一设备根据第二设备发送的资源分配信息，确定第二设备分配的资源。
以上述n个第二设备中的目标第二设备为例，第一设备根据该目标第二设备发送的资源分配信息，确定该目标第二设备为其与第一设备之间传输的直连通信信息所分配的资源。目标第二设备可以是上述n个第二设备中的任意一个第二设备。
可选地，对于上述n个第二设备中的每一个第二设备，第一设备分别根据每一个第二设备发送的资源分配信息，确定该第二设备分配的资源。
在步骤203中，若n个第二设备中的目标第二设备分配的资源满足资源碰撞条件，则第一设备执行资源碰撞解决流程。
资源碰撞条件是指预先设定的确定为发生资源碰撞的条件。可选地，资源碰撞条件包括：目标第二设备分配的资源与其它第二设备分配的资源之间存在重叠资源。重叠资源是指相同的资源。
例如，当资源包括时域资源和频域资源时，如果目标第二设备分配的时域资源与另一第二设备分配的时域资源之间存在相同的时域资源，且目标第二设备分配的频域资源与该另一第二设备分配的频域资源之间存在相同的频域资源，则说明存在重叠资源，满足资源碰撞条件。
又例如，当资源包括时频码空域(也即上文介绍的时域资源、频域资源、码域资源和空域资源)时，如果目标第二设备分配的时频码空域资源与另一第二设备分配的时频码空域资源之间存在相同的时频码空域资源，则说明存在重叠资源，满足资源碰撞条件。上述相同的时频码空域资源是指时域资源、频域资源、码域资源和空域资源均相同，只要有一项不相同，则不重叠。
可选地，资源碰撞条件还包括：重叠资源在目标第二设备分配的资源中的占比和/或重叠资源在其它第二设备分配的资源中的占比大于阈值。该阈值可以在标准或协议中预先规定，或者由基站指示。在本公开实施例中，对该阈值的 取值不作限定，示例性地，该阈值为5％、10％或15％。
示例性地，结合参考图3和图4，假设设备A和设备B分配的资源中，时域资源完全相同，频域资源存在重叠。如图3所示，频域资源仅重叠了一小部分，例如重叠资源在设备A和设备B分配的资源中的占比均为10％，而阈值为15％，则确定该设备A和设备B不满足资源碰撞条件。如图4所示，频域资源存在较大部分重叠，例如重叠资源在设备A和设备B分配的资源中的占比均为50％，而阈值为15％，则确定该设备A和设备B满足资源碰撞条件。
在目标第二设备分配的资源满足资源碰撞条件时，第一设备执行资源碰撞解决流程。资源碰撞解决流程是指解决该资源碰撞问题，避免出现资源碰撞的操作流程。在本公开实施例中，提供了多种资源碰撞解决流程，具体可参见下文实施例中的介绍说明。
另外，若目标第二设备分配的资源不满足资源碰撞条件，则仍然按照该目标第二设备分配的资源传输上述直连通信信息。
需要说明的一点是，只要目标第二设备与n个第二设备中的任意一个其它第二设备之间满足资源碰撞条件，第一设备就需执行资源碰撞解决流程，以解决该资源碰撞问题。
还需要说明的一点是，在目标第二设备与其它第二设备仅存在一小部分重叠资源的情况下，可以不必执行资源碰撞解决流程，仍然按照该目标第二设备分配的资源传输上述直连通信信息，因为即便这小部分重叠资源上传输的直连通信信息无法被成功接收，但根据其它未重叠的资源上传输的直连通信信息，也可以对这部分重叠资源上传输的直连通信信息进行正确解码。
综上所述，本公开实施例提供的技术方案中，通过第一设备接收各个第二设备发送的资源分配信息，根据该资源分配信息，检测出是否存在目标第二设备满足资源碰撞条件，如果存在目标第二设备满足资源碰撞条件，则第一设备执行资源碰撞解决流程，以解决资源碰撞问题；通过上述方式，对于V2X直连通信场景中未来计划占用的资源，也能够检测出是否会出现资源碰撞，提高了资源碰撞问题的解决概率，最大程度上避免资源碰撞发生，充分确保了V2X直连通信场景中信息收发的成功率，且有助于提高频谱效率。
图5是根据另一示例性实施例示出的一种V2X直连通信场景下的资源碰撞解决方法的流程图。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(501～503)。
在步骤501中，第一设备接收n个第二设备各自发送的资源分配信息，n为大于1的整数。
在步骤502中，第一设备根据第二设备发送的资源分配信息，确定第二设备分配的资源。
上述步骤501-502与图2实施例中的步骤201-202相同，参见图2实施例中的介绍说明，本实施例对此不再赘述。
在步骤503中，若n个第二设备中的目标第二设备分配的资源满足资源碰撞条件，则第一设备向目标第二设备发送资源重分配信息。
资源重分配信息用于指示目标第二设备重新分配资源。可选地，资源重分配信息以SCI的形式在PSCCH(Pysical Sidelink Control Channel，物理侧链路控制信道)上发送，或以SFCI(Sidelink Feedback Control Information，侧链路反馈控制信息)的形式在PSFCH(Pysical Sidelink Feedback Channel，物理侧链路反馈信道)上发送。
可选地，资源重分配信息包括：重叠资源的标识信息。重叠资源的标识信息用于唯一指示该重叠资源。重叠资源的标识信息可以采用为资源分配的标识来表示，也可以采用为该重叠资源用于传输的信息所分配的标识来表示。示例性地，如果重叠资源用于传输的是数据，则重叠资源的标识信息可以是该数据所占用的时频资源块的ID(Identity，标识)；如果重叠资源用于传输的是参考信号，则重叠资源的标识信息可以是该参考信号的ID；如果重叠资源用于传输的是PSCCH或PSFCH资源，则重叠资源的标识信息可以是该PSCCH或PSFCH资源所占用的时频资源块的ID，也可以是该PSCCH或PSFCH资源的ID。
另外，目标第二设备接收到第一设备发送的资源重分配信息之后，为其与第一设备之间传输的直连通信信息重新分配资源。目标第二设备可以为之前分配的全部资源所用于传输的直连通信信息，重新分配资源；或者，目标第二设备也可以根据资源重分配信息中包含的重叠资源的标识信息，确定出之前分配的全部资源中的重叠资源，并为该重叠资源所用于传输的直连通信信息重新分配资源。目标第二设备还可以将重新分配的资源通过资源分配信息告知给第一设备。
可选地，上述步骤503之前还包括如下步骤：若目标第二设备分配的资源 满足资源碰撞条件，则第一设备检测目标第二设备是否满足资源重分配条件；若目标第二设备满足资源重分配条件，则第一设备执行上述步骤503，向目标第二设备发送资源重分配信息。其中，资源重分配条件是指预先设定的需要重新分配资源的条件。
可选地，资源重分配条件包括但不限于以下任意一种或多种的组合：
1、重叠资源在目标第二设备分配的资源中的占比，大于重叠资源在其它第二设备分配的资源中的占比；
也即，重叠资源在第二设备分配的资源中的占比越大，越优先向该第二设备发送资源重分配信息。例如，设备A和设备B存在重叠资源，该重叠资源在设备A分配的资源中的占比为50％，在设备B分配的资源中的占比为20％，则优先向设备A发送资源重分配信息。
2、目标第二设备分配的时域资源的起始时刻，晚于其它第二设备分配的时域资源的起始时刻；
也即，第二设备分配的资源中的时域资源的起始时刻越靠后，越优先向该第二设备发送资源重分配信息。例如，设备A为与第一设备之间的通信分配的时域资源为t～t+3，设备B为与第一设备之间的通信分配的时域资源为t+2～t+4，而频域资源一样，所以设备A和设备B存在重叠资源。因为设备A分配的时域资源的起始时刻为t，设备B分配的时域资源的起始时刻为t+2，则第一设备优先向设备B发送资源重分配信息。
需要说明的一点是，第一设备在向目标第二设备发送资源重分配信息之前，可以先检测目标第二设备分配的时域资源的起始时刻与当前时刻之间的时间间隔是否大于预设时长，若大于预设时长，则执行向目标第二设备发送资源重分配信息的步骤，若小于预设时长，则不执行向目标第二设备发送资源重分配信息的步骤。上述预设时长可以在标准或协议中预先规定，或者由基站指示。如果上述时间间隔过短，即便第一设备向目标第二设备发送了资源重分配信息，目标第二设备在向第一设备发送直连通信信息之前也无法成功接收到该资源重分配信息。因此，为了避免执行非必要的操作，可以在发送资源重分配信息之前，先执行上述检测机制。
3、目标第二设备分配的资源所用于传输的直连通信信息的优先级，低于其它第二设备分配的资源所用于传输的直连通信信息的优先级。
也即，第二设备分配的资源所用于传输的直连通信信息的优先级越低，越 优先向该第二设备发送资源重分配信息。直连通信信息的优先级可以根据该直连通信信息的时延要求进行设定，例如直连通信信息的时延要求越高，则优先级越高；反之，直连通信信息的时延要求越低，则优先级越低。例如，设备A分配的资源所用于传输的直连通信信息A的时延要求为5ms以内，设备B分配的资源所用于传输的直连通信信息B的时延要求为10ms以内，则直连通信信息A的时延要求更高，该直连通信信息A的优先级更高，优先向设备B发送资源重分配信息。
需要说明的一点是，当资源分配信息是第二设备为其向第一设备发送的信息分配的资源时，或者当资源分配信息是第二设备为第一设备向其发送的信息分配的资源时，本实施例提供的技术方案均可适用。
综上所述，本实施例提供的技术方案中，通过第一设备在检测到目标第二设备分配的资源满足资源碰撞条件时，向该目标第二设备发送资源重分配信息，以便目标第二设备根据该资源重分配信息重新分配资源，从而避免资源碰撞发生。
另外，当资源分配信息是第二设备为第一设备向其发送的信息所分配的资源时，第一设备还可以采用下述方式执行资源碰撞解决流程，以解决资源碰撞问题。
在一种可能的实施方式中，若第一设备需要向目标第二设备发送的目标直连通信信息的优先级，高于第一设备需要向其它第二设备发送的其它直连通信信息的优先级，则第一设备在重叠资源上仅向目标第二设备发送的目标直连通信信息。
例如，当两个第二设备为第一设备调度了相同的资源用于传输直连通信信息时，第一设备比较在重叠资源上向这两个第二设备发送的直连通信信息的优先级，第一设备在重叠资源上仅向其中一个第二设备(也即直连通信信息的优先级较高的第二设备)发送直连通信信息，而不再在该重叠资源上向另一个第二设备(也即直连通信信息的优先级较低的第二设备)发送直连通信信息。
直连通信信息的优先级可以根据该直连通信信息的时延要求进行设定，例如直连通信信息的时延要求越高，则优先级越高；反之，直连通信信息的时延要求越低，则优先级越低。例如，HARQ(Hybrid Automatic Repeat reQuest，混合自动重传请求)反馈的优先级高于CSI(Channel State Information，信道 状态信息)反馈的优先级，非周期性的CSI反馈的优先级高于周期性的CSI反馈的优先级，等等。或者根据车载通信的不同的信息的时延优先级来设定，比如安全相关的信息的时延优先级，高于交通效率相关的信息的时延优先级，高于娱乐相关的信息的时延优先级。
在另一种可能的实施方式中，第一设备发送合并信息；其中，合并信息包括：第一设备需要向目标第二设备发送的目标直连通信信息、第一设备需要向其它第二设备发送的其它直连通信，以及目标第二设备和其它第二设备的标识信息。
例如，当两个第二设备为第一设备调度了相同的资源用于传输直连通信信息时，第一设备将在重叠资源上向这两个第二设备发送的直连通信信息进行合并(multiplexing)，生成合并信息，然后在该重叠资源上将合并信息发送出去。例如，当第一设备没有充足的时间向这两个第二设备发送资源重分配信息时，第一设备可以采用这种方式，在重叠资源上将合并信息发送出去。由于合并信息中包括各个接收端设备的标识信息，因此某一设备在接收到合并信息之后，可以检测该合并信息中是否包括自身的标识信息，如果合并信息中包括自身的标识信息，则从中解码获取发送给自身的信息。
需要说明的一点是，第二设备为第一设备调度的资源所用于传输的直连通信信息，可以是通过PSCCH或PSFCH传输的直连通信信息，如CSI反馈、HARQ反馈等，也可以是通过PSSCH(Pysical Sidelink Share Channel，物理侧链路共享信道)传输的直连通信信息，如CSI反馈、HARQ反馈、数据等。
综上所述，本实施例提供的两种方式，同样可以解决资源碰撞问题。
图6是根据另一示例性实施例示出的一种V2X直连通信场景下的资源碰撞解决方法的流程图。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(601～602)。
在步骤601中，第二设备向第一设备发送资源分配信息。
资源分配信息用于指示第二设备为其与第一设备之间传输的直连通信信息所分配的资源。
可选地，该直连通信信息包括第二设备通过侧链路向第一设备发送的信息；或者，该直连通信信息包括第一设备通过侧链路向第二设备发送的信息。
在步骤602中，第二设备接收第一设备执行资源碰撞解决流程时发送的信 息。
资源碰撞解决流程是在第二设备分配的资源满足资源碰撞条件的情况下执行的。资源碰撞条件包括：第二设备分配的资源与其它设备分配的资源之间存在重叠资源。可选地，资源碰撞条件还包括：重叠资源在第二设备分配的资源中的占比和/或重叠资源在其它设备分配的资源中的占比大于阈值。
