为了更清楚地说明本公开实施例的技术方案，下面将对本公开实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
如图1所示，为相关技术中V2X(Vehicle to Everything)通信示意图。设备和设备之间允许直接进行设备之间的直接通信。为了便于描述，定义设备和设备之间的直接通信链路为Sidelink(直通)链路，其对应的无线接口称为直接通信接口(也称为Sidelink接口)；网络与直接通信设备之间的蜂窝通信链路称之为Uu link，其对应的接口称为Uu接口。
直接通信的设备也可以均是在网的，或者均是脱网的，还可以是部分设备在网，部分设备脱网。所谓在网即参与直接通信的设备位于3GPP基站通信载波覆盖范围内，所谓脱网即参与直接通信的设备不在3GPP基站通信载波覆盖范围内。
典型的直接通信通信场景包括如下三种：直接通信终端之间一对一通信(单播)；一个设备一次可以给一个通信群组里的所有设备发送相同数据(组播)；一个设备一次可以给所有附近的设备发送相同数据(广播)。
LTE***中直接通信接口支持两种资源分配方式：
网络调度的资源分配模式：即由网络根据终端上报的Sidelink BSR(Buffer status reporting，缓冲区状态上报)为终端分配资源的方式(也称为Mode 3)。
终端自主选择的资源分配模式：即终端自行从预配置或者网络广播的发送资源中选择一个资源进行直接通信链路的发送(也称为Mode 4)。
NR***中直连通信中的网络调度的资源分配模式称为Mode 1,终端自选 的资源分配模式称为Mode 2。对于Mode2，又细分为4种子模式：
Mode 2a：终端自选的资源分配模式；
Mode2b：终端辅助其他终端选择资源分配模式；
Mode2c：基于网络配置授权的终端资源分配模式；
Mode2d：终端调度其他终端的资源分配模式。
因此，由以上可以看出，对于NR，直接通信接口的业务相对LTE会更加丰富，引入了Mode2d终端调度其他终端的资源分配模式。而相关技术中并没有关于如何确定调度终端等的方案。
为解决上述问题，本公开实施例提供了一种信息处理方法及装置。以下，结合具体的实施例详细描述一下具体的实现方案。
参见图2，图2是本公开实施例提供的信息处理方法的流程图，应用于第一终端。如图2所示，包括以下步骤：
步骤201、接收第二终端发送的第一指示信息，所述第一指示信息用于指示所述第二终端可以调度侧行链路资源；所述第二终端的数量大于或等于1个。
其中，在本公开实施例中，第二终端可以调度侧行链路资源，也即，第二终端是具有调度侧行链路资源能力的终端。
在实际应用中，为便于第一终端获得该指示信息，此步骤可具体为：接收所述第二终端发送的广播信号，在所述广播信号中携带所述第一指示信息；和/或，接收所述第二终端发送的同步信号，在所述同步信号中携带所述第一指示信息。
所述第一指示信息包括：终端类型和/或终端标识，所述终端类型用于表示所述第二终端为可以调度侧行链路资源的终端。
若所述第一指示信息中只包括终端标识，那么第一终端可根据预先约定或者网络配置，根据终端标识确定第二终端是否可以调度侧行链路资源。例如，组播场景中，一个终端组中的组头(管理该组中终端的终端)即为可以调度侧行链路资源的第二终端；又例如，单播场景中，发送终端(或者发起建立单播连接的终端)即为可以调度侧行链路资源的第二终端。
所述第一指示信息可以显示的包含在所述广播信号和/或同步信号中，例 如，广播信号中的M比特为第一指示信息，M为大于0的正整数。
所述第一指示信息也可以隐式的包含在所述广播信号和/或同步信号中，例如，第一指示信息可以为特定的序列或者生成特定序列的特定种子，可以调度侧行链路资源的第二终端使用该特定的序列加扰其发送的广播信号和/或同步信号，从而表示该所述第二终端为可以调度侧行链路资源的终端。
此外，为了便于第一终端选择第二终端发送侧行链路资源，所述广播信号中还包括以下至少一项信息：所述第二终端可分配的资源所在的频带(band)；所述第二终端可分配的资源的图样，如半静态调度图样(SPS pattern)或配置授权图样(configured grant pattern)。
本公开实施例中，第一终端可根据第二终端发送的第一指示信息确定第二终端是可以调度侧行链路资源，从而实现了在NR Mode2中确定调度终端。
在上述实施例的基础上，为便于获得侧行链路资源，所述方法还可包括：
从所述第二终端中选择目标第二终端；
其中，所述目标第二终端的数量为整数，且所述目标第二终端的数量小于或等于所述第二终端的数量。
具体地，可以将发送的广播信号和/或同步信号的接收功率超过第一预设值的第二终端，作为所述目标第二终端。其中，该第一预设值可任意设置，可以是标准规定的，或者网络设备配置的，或者预配置的。
在实际应用中，根据广播信号和/或同步信号中包括的信息，可以将发送的广播信号和/或同步信号的接收功率超过第一预设值且可分配的资源所在的频带为所述第一终端支持的频带的第二终端，作为所述目标第二终端；或者，还可将发送的广播信号和/或同步信号的接收功率超过第一预设值且可分配的资源的图样满足所述第一终端支持的业务的需求的第二终端，作为所述目标第二终端。
若当前选择的目标第二终端无法满足需求，那么，还可在满足触发条件的情况下，触发所述第一终端重新选择目标第二终端。
其中，所述触发条件可以是以下任意一项：
(1)所述目标第二终端的广播信号和/或同步信号的接收功率小于第二预设值；该第二预设值可任意设置，可以是标准规定的，或者网络设备配置 的，或者预配置的。
(2)所述目标第二终端的可分配的资源所在的频带无法满足所述第一终端的业务发送需求。可选地，第二终端不能调整可分配资源的频带。
(3)所述目标第二终端的可分配的资源无法满足所述第一终端的业务量需求。可选地，第二终端不能调整可分配的资源。
(4)所述第一终端向所述目标第二终端发送的用于申请资源的信令的次数大于第三预设值，且未收到所述目标第二终端分配的资源。该第三预设值可任意设置，可以是标准规定的，或者网络设备配置的，或者预配置的。
(5)所述目标第二终端分配的资源无法满足所述第一终端的发送时延或者可靠性要求。可选地，第二终端不能调整可分配的资源。
为避免误触发重选，所述第二预设值包括第四预设值和第五预设值，其中，所述第四预设值大于所述第五预设值。那么，此步骤具体为：在所述目标第二终端的广播信号和/或同步信号的接收功率小于所述第四预设值且大于所述第五预设值的情况下，触发所述第一终端重新选择目标第二终端，其中，所述第一终端不切换目标第二终端；在所述目标第二终端的广播信号和/或同步信号的接收功率小于所述第五预设值的情况下，所述第一终端切换目标第二终端。该第四预设值和第五预设值可任意设置，可以是标准规定的，或者网络设备配置的，或者预配置的。
那么，在选择了目标第二终端后，若选择的目标第二终端的数量大于0，则可接收选择的目标第二终端分配的侧行链路资源。若未选择出目标第二终端，那么，则可通过除Mode2d之外的任意模式获取侧行链路资源，例如，Mode1，Mode 2a，Mode 2b，Mode 2c等等。
参见图3，图3是本公开实施例提供的信息处理方法的流程图，应用于第二终端。如图3所示，包括以下步骤：
步骤301、向第一终端发送第一指示信息，所述第一指示信息用于指示所述第二终端可以调度侧行链路资源；所述第二终端的数量大于或等于1个。

向所述第一终端发送广播信号，在所述广播信号中携带所述第一指示信息；和/或，向所述第一终端发送同步信号，在所述同步信号中携带所述第一 指示信息。
其中，所述第一指示信息包括：终端类型和/或终端标识，所述终端类型用于表示所述第二终端为可以调度侧行链路资源的终端。
若所述第一指示信息中只包括终端标识，那么第一终端可根据预先约定或者网络配置，根据终端标识确定第二终端是否可以调度侧行链路资源。例如，组播场景中，一个终端组中的组头(管理该组中终端的终端)即为可以调度侧行链路资源的第二终端；又例如，单播场景中，发送终端(或者发起建立单播连接的终端)即为可以调度侧行链路资源的第二终端。
所述第一指示信息可以显示的包含在所述广播信号和/或同步信号中，例如，广播信号中的M比特为第一指示信息，M为大于0的正整数。
所述第一指示信息也可以隐式的包含在所述广播信号和/或同步信号中，例如，第一指示信息可以为特定的序列或者生成特定序列的特定种子，可以调度侧行链路资源的第二终端使用该特定的序列加扰其发送的广播信号和/或同步信号，从而表示该所述第二终端为可以调度侧行链路资源的终端。
为便于第一终端选择第二终端，所述广播信号中还包括以下至少一项信息：所述第二终端可分配的资源所在的频带；所述第二终端可分配的资源的图样。
本公开实施例中，第一终端可根据第二终端发送的第一指示信息确定第二终端是可以调度侧行链路资源，从而实现了在NR Mode2中确定调度终端。
为使得第一终端获得侧行链路资源，在上述实施例的基础上，所述方法还可包括：在所述第二终端为目标第二终端的情况下，向所述第一终端发送侧行链路资源。

具体地，可将广播信号和/或同步信号的接收功率超过第一预设值且可分配的资源所在的频带为所述第一终端支持的频带的第二终端，作为所述目标第二终端；或者，可将广播信号和/或同步信号的接收功率超过第一预设值且可分配的资源的图样满足所述第一终端支持的业务的需求的第二终端，作为所述目标第二终端。其中，该第一预设值可任意设置，可以是标准规定的，或者网络设备配置的，或者预配置的。
为便于第一终端选择目标第二终端，所述广播信号中携带第一指示信息，和/或，在所述同步信号中携带第一指示信息；所述第一指示信息用于指示所述第二终端可以调度侧行链路资源。所述第一指示信息包括：终端类型和/或终端标识，所述终端类型用于表示所述第二终端为可以调度侧行链路资源的终端。

步骤501、向第一终端发送广播信号和/或同步信号，以使所述第一终端根据所述广播信号和/或同步信号，从所述第二终端中选择目标第二终端。
其中，所述第二终端可以调度侧行链路资源，所述第二终端的数量大于或等于1个，所述目标第二终端的数量为整数，且所述目标第二终端的数量小于或等于所述第二终端的数量。
为便于第一终端选择目标第二终端，所述广播信号中携带第一指示信息；和/或，在所述同步信号中携带第一指示信息；所述第一指示信息用于指示所述第二终端可以调度侧行链路资源。所述第一指示信息包括：终端类型和/或终端标识，所述终端类型用于表示所述第二终端为可以调度侧行链路资源的终端。
若所述第一指示信息中只包括终端标识，那么第一终端可根据预先约定或者网络配置，根据终端标识确定第二终端是否可以调度侧行链路资源。例如，组播场景中，一个终端组中的组头(管理该组中终端的终端)即为可以调度侧行链路资源的第二终端；又例如，单播场景中，发送终端(或者发起建立单播连接的终端)即为可以调度侧行链路资源的第二终端。
所述第一指示信息可以显示的包含在所述广播信号和/或同步信号中，例如，广播信号中的M比特为第一指示信息，M为大于0的正整数。
所述第一指示信息也可以隐式的包含在所述广播信号和/或同步信号中，例如，第一指示信息可以为特定的序列或者生成特定序列的特定种子，可以调度侧行链路资源的第二终端使用该特定的序列加扰其发送的广播信号和/或同步信号，从而表示该所述第二终端为可以调度侧行链路资源的终端。
此外，所述广播信号中还包括以下至少一项信息：所述第二终端可分配的资源所在的频带；所述第二终端可分配的资源的图样，如半静态调度图样或配置授权图样等。
本公开实施例中，第一终端可根据第二终端发送的广播信号和/或同步信号，从所述第二终端中选择目标第二终端，从而实现了在NR Mode2中选择调度终端。
下面实施例以NR的直连***中单播业务为例进行说明。组播业务时类 似，区别在于有多个接收终端。
如图6所示，第一终端初始选择目标第二终端的过程包括：
步骤601、第一终端接收第二终端发送的广播信号或同步信号。
其中，第二终端发送的广播信号是周期性广播的，其中包括：
(1)终端类型指示信息：例如，使用M比特指示其为调度终端，M为大于零的正整数，例如M＝3，为“000”时，表示该终端为可以调度侧行链路资源的调度终端；又例如，终端类型指示信息为序列N，或者为生成序列N的种子，使用序列N对广播信息进行加扰；
(2)可选地，终端可分配的资源所在的频带(band)；
(3)可选地，终端可分配的资源的图样(pattern)，例如SPS pattern或configured grant pattern等；
(4)终端ID。
此时，可设置备选集合为空。该备选集合用于存储可供第一终端选择的第二终端的信息。
步骤602、第一终端判断第二终端的广播信号或同步信号接收功率是否超过预设值。
其中，该预设值可以由标准规定，或***配置，或预配置。如果接收功率超过了该预设值，则该第二终端为备选终端，放到备选集合中。如果接收功率低于门限，说明第一终端距离该第二终端较远，则排除该第二终端。
步骤603、第一终端判断第二终端支持的可分配的资源所在的频段是否满足需求。
具体地，第一终端根据第二终端的广播消息中携带的可分配的资源所在的频带信息，判断第二终端支持的可分配的资源所在的频段是否满足需求。如果满足需求，则该第二终端为备选终端，放到备选集合中；如果不满足需求，则从备选集合中排除该第二终端。
步骤604、第一终端判断第二终端支持的可分配的资源是否满足业务需求。
其中，业务需求包括：时延需求、可靠性需求或者业务量需求等。第一终端根据第二终端的广播消息中携带的可分配的资源的图样，例如SPS pattern 或configured grant pattern等，判断第二终端支持的可分配的资源是否满足业务需求。如果满足需求，则该第二终端为备选终端，放到备选集合中；如果不满足需求，则从备选集合中排除该第二终端。
其中，步骤603和步骤604是可选的步骤。且，步骤603和步骤604之间并无先后关系。也即，还可在步骤602的基础上先进行步骤604的判断，然后，再在步骤604的基础上进行步骤603的判断。
步骤605、确定备选集合中是否有合适终端。
步骤606、若该备选集合中为空，则第一终端通过其他模式(例如，mode1或mode2a或mode2c等)获得侧行链路资源。
步骤607、第一终端选择第二终端。
若该备选集合中有且仅有一个第二终端，则第一终端选择该第二终端，并从该第二终端获得侧行链路资源。若该备选集合中有大于一个第二终端，则第一终端在该备选集合中选择一个或多个第二终端，并从该一个或多个第二终端获得侧行链路资源。
具体第一终端如何在该备选集合中选择一个或多个第二终端，属于终端实现。例如第一终端可以随机选择一个或多个第二终端，或者按照第二终端的可分配的资源选择可以分配时延更短或者可靠性更高的资源的第二终端。
如图7所示，第一终端重选第二终端的过程包括：
步骤701、第一终端接收第二终端发送的广播信号或同步信号。
其中，第二终端发送的广播信号是周期性广播的，其中包括：
(1)终端类型指示信息：例如，使用M比特指示其为调度终端，M为大于零的正整数，例如M＝3，为“000”时，表示该终端为调度终端；又例如，终端类型指示信息为序列N，或者为生成序列N的种子，使用序列N对广播信息进行加扰；
(2)可选地，终端可分配的资源所在的频带；
(3)可选地，终端可分配的资源的图样，例如SPS pattern或configured grant pattern等；
(4)终端ID。
步骤702、第一终端判断第二终端的广播信号或同步信号接收功率是否 低于门限1。
其中，该门限1可以由标准规定，或***配置，或预配置。如果接收功率低于门限1，则触发第一终端搜索并接收其他第二终端的广播信号或同步信号；如果不低于门限1，则继续从该第二终端获得侧行链路资源。第一终端进行搜索并接收其他第二终端的广播信号或同步信号的步骤同图6所示的实施例，这里不再赘述。
步骤703、第一终端判断第二终端的广播信号或同步信号接收功率是否低于门限2。
其中，该门限2可以由标准规定，或***配置，或预配置。如果低于门限2，则触发第一终端选择/切换到其他第二终端或其他资源分配模式，具体的选择步骤同图6所示的实施例，这里不再赘述。如果不低于门限2，则返回步骤702判断是否低于门限1。
也即，在此实施例中，配置2个门限：门限1和门限2，门限1的功率大于门限2的功率。当第二终端的广播信号和/或同步信号接收功率低于门限1但高于门限2时，触发重选，第一终端搜索并选择其他备选第二终端，但并不实际发生切换。只有当第二终端的广播信号和/或同步信号接收功率低于门限2时，才发生切换，第一终端从该第二终端切换到之前选好的其他第二终端。这样设置的好处是为了避免虚警，比如低于门限1只是暂时现象，可能一段时间又高于门限1。
之后，第一终端选择第二终端。具体包括：
步骤704、确定备选集合中是否有合适终端。
步骤705、若该备选集合中为空，则第一终端通过其他模式(例如，mode1或mode2a或mode2c等)获得侧行链路资源。
步骤706、第一终端选择第二终端。
若该备选集合中有且仅有一个第二终端，则第一终端选择该第二终端，并从该第二终端获得侧行链路资源。若该备选集合中有大于一个第二终端，则第一终端在该备选集合中选择一个或多个第二终端，并从该一个或多个第二终端获得侧行链路资源。
具体第一终端如何在该备选集合中选择一个或多个第二终端，属于终端 实现。例如第一终端可以随机选择一个或多个第二终端，或者按照第二终端的可分配的资源选择可以分配时延更短或者可靠性更高的资源的第二终端。
如图8所示，第一终端重选第二终端的过程包括：
步骤801、第一终端接收第二终端发送的广播信号或同步信号。
其中，第二终端发送的广播信号是周期性广播的，其中包括：
(1)终端类型指示信息：例如，使用M比特指示其为调度终端，M为大于零的正整数，例如M＝3，为“000”时，表示该终端为调度终端；又例如，终端类型指示信息为序列N，或者为生成序列N的种子，使用序列N对广播信息进行加扰；
(2)可选地，终端可分配的资源所在的频带；
(3)可选地，终端可分配的资源的图样，例如SPS pattern或configured grant pattern等；
(4)终端ID。
步骤802、第一终端判断第二终端的广播信号或同步信号接收功率是否低于门限3。
其中，该门限3可以由标准规定，或***配置，或预配置。如果接收功率低于门限3，则触发第一终端搜索并接收其他第二终端的广播信号或同步信号，并选择合适的其他第二终端。如果不低于门限3，则继续从该第二终端获得侧行链路资源。
第一终端进行搜索并接收其他第二终端的广播信号或同步信号的步骤，以及选择合适的其他第二终端的步骤同图6所示的实施例，这里不再赘述。
第一终端选择第二终端，具体包括：
步骤803、确定备选集合中是否有合适终端。
步骤804、若该备选集合中为空，则第一终端通过其他模式(例如，mode1或mode2a或mode2c等)获得侧行链路资源。
步骤805、第一终端选择第二终端。
若该备选集合中有且仅有一个第二终端，则第一终端选择该第二终端，并从该第二终端获得侧行链路资源。若该备选集合中有大于一个第二终端，则第一终端在该备选集合中选择一个或多个第二终端，并从该一个或多个第 二终端获得侧行链路资源。
具体第一终端如何在该备选集合中选择一个或多个第二终端，属于终端实现。例如第一终端可以随机选择一个或多个第二终端，或者按照第二终端的可分配的资源选择可以分配时延更短或者可靠性更高的资源的第二终端。
也即，在此实施例中，只配置1个门限3，只要广播信号和/或同步信号的接收功率低于该门限3，就触发重选。
除了以上实施例中描述的触发重选的条件，在本公开实施例中，触发重选的条件还可包括：
(1)当第二终端支持的可分配资源的band不能满足第一终端的业务发送需求时，并且可选地，第二终端不能调整可分配资源的band时，则触发重选。
(2)当第一终端向第二终端发送了K次申请资源信令，K为大于0的正整数，都没有接收到第二终端分配的资源，则触发重选。
(3)当第二终端可分配的资源不足以满足第一终端的业务量需求，并且可选地，第二终端不能调整可分配的资源时，触发重选。
例如，第一终端的业务量较大，需要传输的信息较多，或者同时和多个终端发送不同的侧行链路信息，此时，如果第二终端可分配的资源较少，则会造成业务延时较大，或者可靠性降低，则第一终端会触发重选。
第一终端触发重选时，可以保留当前第二终端，并选择其他第二终端用于补充可分配的资源，也可以不保留当前第二终端，直接选择其他满足资源需求的第二终端。
(4)当第二终端分配的资源不能满足第一终端的业务的发送时延或业务的可靠性要求时，并且可选地，第二终端不能调整可分配的资源时，则触发重选。
由上可以看出，利用本公开实施例的方案，可解决mode 2d模式中被调度终端选择或重选调度终端的问题，使得被调度终端可以选择合适的调度终端。
