Description

信息传输方法、资源配置方法及设备 技术领域
本发明涉及通信技术领域，尤其涉及信息传输方法、资源配置方法及设备。
背景技术
车与外界(英文：vehicle-to-X，简称：V2X)的信息交换，是指车辆与车辆(英文：vehicle-to-vehicle，简称：V2V)、车辆与基础设施(英文：vehicle-to-infrastructure，简称：V2I)、以及车辆与行人(英文：vehicle-to-pedestrian，简称：V2P)等之间的通信。通过V2X通信可以实现提高道路安全、提高交通效率、以及为用户提供丰富的流媒体服务的目的。
目前，在基于V2X通信场景中，终端设备可以使用基站为终端设备配置的资源池、或者终端设备的预配置资源池中的资源进行信息传输。该终端设备可以是车辆、基础设施、以及行人的手持设备等。在进行信息传输时，终端设备可以随机的从该资源池中选取部分资源，然后利用选取的资源进行信息传输，这种方式称为随机选择方式。但是，在使用随机选择方式时，若多个终端设备选择了相同的资源，则会导致多个终端设备之间的信息传输发生冲突。进而，为了解决该冲突问题，提出了一种侦听选择方式，即终端设备对资源池中的资源先侦听一段时间，得到资源池中未被使用的资源，再从这些未被使用的资源中选择部分或者全部资源来进行信息传输。
但是，在使用侦听选择方式时，终端设备进行侦听时需要消耗大量的功率，特别是对于主要能量来自像电池等能量储存较少的终端设备来说，大大增加了终端设备的能量消耗，进而降低了用户体验。

图4为本发明实施例提供的一种信息传输方法的流程示意图，参见图4，该方法包括以下几个步骤。
步骤201：终端设备从候选资源池中选择目标资源池；其中，候选资 源池包括基于随机选择方式的第一类资源池和基于侦听选择方式的第二类资源池。
其中，该终端设备可以为上述图1中的第一终端设备或第二终端设备，且该终端设备可以为车辆。
另外，第一类资源池包括至少一个资源池，随机选择方式是指终端设备可以从第一类资源池包括的至少一个资源池中随机地选择资源池中的部分资源。第二类资源池包括至少一个资源池，侦听选择方式是指终端设备可以对第二类资源池包括的至少一个资源池中的资源进行侦听，从而可以得到至少一个资源池中未被占用的资源。
当终端设备从候选资源池中选择目标资源池时，终端设备可以随机的或者按照预设的选择规则等，从第一类资源池或者第二类资源池中选择目标资源池。
可选的，当终端设备从候选资源池中选择目标资源池时，可以按照终端设备的类型进行选择，具体为：若终端设备为第一类型的终端设备，则从候选资源中选择第一类资源池作为目标资源池；若终端设备为第二类型的终端设备，则从候选资源中选择第一类资源池或第二类资源池作为目标资源池。
其中，第一类型和第二类型的终端设备根据资源选择方式来划分；其中不支持侦听选择方式的终端，即仅支持随机选择方式的终端划分为第一类型终端；支持侦听选择方式的终端划分为第二类型终端。
另外，当终端设备从候选资源池中选择目标资源池时，还可以按照基站的指示信息，从候选资源池中选择目标资源池，具体为：终端设备接收基站发送的指示信息，若该指示信息用于指示终端设备选择第一类资源池或者以随机选择方式进行选择，则终端设备可以将第一类资源池作为目标资源池。若该指示信息用于指示终端设备选择第二类资源池或者以侦听选择方式进行选择，则终端设备可以将第二类资源池作为目标资源池。若该指示信息不限定终端设备的目标资源池或者选择方式，则终端设备可以将第一类资源池作为目标资源池，也可以将第二类资源池作为目标资源池。
进一步的，在终端设备接收基站发送的指示信息之前，还可以包括：终端设备向基站发送设备参数信息和/或资源请求信息。该设备参数信息 包括终端设备的电源供电类型、设备能力、设备剩余能量信息、设备倾向的资源选择方式中的一项或者多项。资源请求信息包括终端设备进行V2X业务或P2X业务的指示信息。当基站接收到该设备参数信息和/或资源请求信息时，基站可以向终端设备发送指示信息，以使终端设备根据该指示信息从候选资源池中选择目标资源池。
其中，终端设备的电源供电类型可以是像电池等能量储存较少的设备供电类型，也可以是能量主要来自像车辆发动机等设备供电类型。
终端设备的设备能力可以包含以下能力的中的一种或者多种：终端设备支持随机选择资源或基于侦听的资源选择的能力、终端设备在多个载波组合上同时发送和/或接收侧向链路的能力。
设备剩余能量信息可以是设备剩余能量值和/或剩余能量占总能量的百分比。
设备本身倾向采用的资源选择方式包括基于随机选择方式和基于侦听选择方式。
步骤202：若目标资源池为第一类资源池，终端设备按照随机选择方式使用第一类资源池中的资源进行信息传输；若目标资源池为第二类资源池，终端设备按照侦听选择方式使用第二类资源池中的资源进行信息传输。
当终端设备选择的目标资源池为第一类资源池时，终端设备可以随机从第一类资源池中选取部分资源，并利用选取的部分资源与基站或者其他终端设备进行信息传输。可选的，在第一类资源池包括至少一个资源池时，终端设备可以随机地从至少一个资源池中选择一个资源池，或者按照预设顺序从至少一个资源池中选择一个资源池，之后从选择的资源池中随机选取部分资源。
当终端设备选择的目标资源池为第二类资源池时，终端设备可以对第二类资源池中的资源进行侦听，得到第二类资源池中未被占用的资源，并选取未被占用的资源中的一部分资源或者全部资源与基站或者其他终端设备进行信息传输。可选的，在第二类资源池包括至少一个资源池，且终端设备对第二类资源池进行侦听时，终端设备可以随机地或者按照预设顺序选择第二类资源池中的一个或者多个资源池进行侦听，得到该一个或者多 个资源池中未被占用的资源。或者，终端设备对第二类资源池包括的至少一个资源池中的每个资源池都进行侦听，得到每个资源池中未被占用的资源。之后，从未被占用的资源中选取进行信息传输的资源。
其中，图4中以终端设备与基站进行信息传输为例说明。
进一步的，参见图5，在步骤201之前，该方法还包括步骤203。
步骤203：基站向终端设备发送配置信息，该配置信息包括候选资源池的信息和资源指示信息，资源指示信息用于指示第一类资源池和第二类资源池的资源选择方式。
其中，基站可以通过广播消息或者通过无线资源控制消息RRC向终端设备发送配置信息。该候选资源池的信息可以是指候选资源池包括的第一类资源池和第二类资源池的频域信息和/或时域信息。比如，该频域信息可以是第一类资源池和第二类资源池所包括的物理资源块的频域范围，或者子载波位置和宽度、以及子载波间隔等。时域信息可以是对应的子帧信息等。资源指示信息用于指示第一类资源池的资源选择方式为随机选择方式，第二类资源池的选择方式为侦听选择方式。
另外，基站还可以确定候选资源池，具体可以为：基站从频域资源中随机地或者按照一定的规则等选取第一类资源池和第二类资源池。之后，基站可以通过广播消息或者无线资源控制消息等将候选资源池的信息发送给终端设备。当终端设备接收候选资源池的信息时，终端设备可以按照上述步骤201-202所述的方法进行信息传输。
进一步的，该配置信息还包括用于指示第一类资源池支持第二类型的终端设备使用的信息，从而步骤201中终端设备从候选资源池中选择目标资源池，包括：若终端设备为第二类型的终端设备，终端设备从候选资源中选择第一类资源池作为目标资源池。
具体的，当第一类资源池支持第二类型的终端设备使用时，第二类型的终端设备也可以选择第一类资源池作为目标资源池。之后，第二类型的终端设备可以按照随机选择方式通过第一类资源池中的资源进行信息传输。
进一步的，参见图6，该方法还包括步骤204。其中，步骤204与步骤201和步骤202不分先后顺序。
步骤204：若终端设备的全球导航卫星***(英文：global navigation satellite system，简称：GNSS)信号丢失或者终端设备的GNSS信号不可靠时，终端设备确定同步基准时间，并按照确定的同步基准时间使用目标资源池进行信息传输。
可选的，终端设备根据基站同步时间和偏差时间，确定一个同步基准时间；其中，该同步基准时间可以作为终端设备进行通信的时间基准；偏差时间是指基站时间基站同步时间与GNSS时间之差，偏差时间由基站配置或者终端设备预配置。
进一步的，参见图7，该方法还包括步骤205。其中，步骤204与步骤201和步骤202不分先后顺序，且步骤205与步骤204是终端设备在两种不同情况下选择目标资源池并进行信息传输的方法。
步骤205：若终端设备的位置信息丢失，终端设备从特殊资源池中选择目标资源池，或者随机的选择一个或者多个区域对应的资源池为目标资源池，或者，选择所有区域对应的资源池中拥塞程度(英文：channel busy ratio，简称：CBR)最小的一个或者多个资源池为目标资源池，并按照目标资源池对应的资源选择方式使用目标资源池进行信息传输。
其中，特殊资源池的信息用于指示特殊资源池和特殊资源池对应的资源选择方式。特殊资源池的信息可以是基站发送给终端设备的，基站可以通过广播消息或者RRC消息为终端设备发送配置信息的方式向终端设备发送包含特殊资源池的信息，也可以是终端设备侧预配置的资源池和资源池上的资源选择方式。图7中以基站通过配置信息向终端设备发送包含特殊资源池的信息为例进行说明。
另外，特殊资源池包括基于随机选择方式的资源池和/或基于侦听选择方式的资源池。特殊资源池是专用于终端设备的位置信息丢失时选择信息传输资源的资源池。该特殊资源池的频域位置与候选资源池的频域位置不同。特殊资源池可以包括至少一个基于随机选择方式的资源池，和/或至少一个基于侦听选择方式的资源池。
当终端设备的位置信息丢失，且从特殊资源池中选择目标资源池之后，若终端设备选择的目标资源池是基于随机选择方式的资源池，终端设备可以按照随机选择方式使用基于随机选择方式的资源池中的资源进行 信息传输。若选择的目标资源池是基于侦听选择方式的资源池，终端设备可以按照侦听选择方式使用基于侦听选择方式的资源池中的资源进行信息传输。
可选的，若终端设备的位置信息丢失，且不存在特殊资源池时，终端设备可以随机的选择一个或者多个区域对应的资源池为目标资源池，并按照所述目标资源池对应的资源选择方式使用所述目标资源池进行信息传输。其中，该多个区域可以为3GPP中定义的区域(zone)，且***为每个区域配置了相应的资源池，相邻的两个区域配置不同的资源池，从而该多个区域对应的资源池即为***为每个区域配置的资源池。
可选的，若终端设备的位置信息丢失，且不存在特殊资源池时，终端设备可以对所有区域对应的资源池进行测量，得到每个资源池的拥塞程度，该拥塞程度可以以信道繁忙率CBR进行衡量，选择所有区域对应的资源池中拥塞程度最小的一个或者多个资源池为目标资源池，并按照目标资源池对应的资源选择方式使用目标资源池进行信息传输。其中，该多个区域可以为3GPP中定义的区域(zone)，且***为每个区域配置了相应的资源池，相邻的两个区域配置不同的资源池，从而该多个区域对应的资源池即为***为每个区域配置的资源池。
可选的，在多个区域对应的资源池上使用的资源选择方式可以随机资源选择也可以使侦听资源选择。可选的，在多个区域对应的资源池上使用的资源选择方式可以是预配置的。
本发明实施例提供的信息传输方法中，终端设备通过从候选资源池包括的第一类资源池或者第二类资源池中选择目标资源池，并基于相应的资源选择方式使用选择的资源池中的资源进行信息传输，从而使不同的终端设备在不同的资源上进行信息传输，进而在避免终端设备之间发生冲突的同时，减小终端设备的消耗功率，提高了用户体验。另外，终端设备还可以在位置信息等丢失的情况下，从特殊资源池选择信息传输的资源，避免了大量终端设备在相同区域丢失位置信息时使用相同资源池造成信息传输冲突的问题。
