具体实施方式
本申请说明书和权利要求书及附图说明中的术语“第一”、“第二”和“第三”等是用于区别不同对象，而不是用于限定特定顺序。
在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
为了下述各实施例的描述清楚简洁，首先给出相关技术的简要介绍：
本申请实施例提供一种确定辅助信息资源块的方法及装置，该方法可以应用于车联网，例如V2X通信和车间通信长期演进技术(long term evolution-vehicle，LTE-V)等，或可以用于智能驾驶和智能网联车等领域。
参见图1所示的场景示意图，V2X通信包含车辆与多种事物的通信，比如车与车的之间通信(vehicle to vehicle，V2V)、车与行人的通信(vehicle to pedestrian，V2P)、车与基础设施的通信(vehicle to infrastructure，V2I)、车与网络设备的通信(vehicle to network，V2N)。其中，该车辆为车联网中具备通信能力的车辆。
在一种可行的实现方式中，车联网内的终端设备包括所述车辆。或者，所述终端设备包括车载通信模块或其它嵌入式通信模块。或者，所述终端设备还可以包括其他类型的通信设备，例如手机、平板电脑或智能穿戴设备等。
另外，终端设备可通过V2X通信技术，与网络设备进行通信。该网络设备可包括多种类型。可选的，在通用移动通信系统/长期演进(universal mobile telecommunications system/long term evolution，UMTS/LTE)中，该网络设备可为传统的宏基站(evolved node B，eNB)；在异构网络(heterogeneous network，HetNet)场景下，该网络设备可为微基站eNB；在分布式基站场景下，该网络设备可为基带处理单元(Base Band Unit，BBU)或射频单元(Remote Radio Unit，RRU)；在云无线接入网(Cloud Radio Access Netowrk，CRAN)场景下，该网络设备可为基带池BBU pool或射频单元RRU；在未来无线通信系统中，所述网络设备可以是gNB。
V2X通信技术定义了两种空口，一种为陆地无线接入网络和用户设备(utran ue，Uu)空口，该空口用于实现终端设备与网络设备之间的通信，例如，终端设备可通过Uu空口，与gNB之间进行通信；另一种为侧行链路空口(sidelink空口，SL空口)，该空口用于实现不同终端设备之间的通信，即终端设备之间通过SL空口进行通信。
另外，在V2X通信的通信场景包括单播(unicast)、组播(groucast)和广播(broadcast)三种类型。其中，组播为“一对一组”的通信模式，在组播场景下，多个终端设备可加入一个相同的组，这一组终端设备共享同一数据流，从而能够节省网络资源。
为了明确组播的通信场景，本申请提供一个示例。参见图2所示的组播场景示意图，该示例呈现的是“一对四”的通信模式，即一个终端设备向四个终端设备发送信息，这四个终端设备即为一组。
进一步的，V2X通信技术还定义两种为终端设备分配资源的模式，在第一种模式(即Mode 1模式)中，网络设备实时动态调度终端设备在SL空口上的资源；在第二种模式(即Mode 2模式)中，网络设备为终端设备配置在SL空口上的资源池，终端设备通过感知V2X网络中各个终端设备的资源占用情况，确定所述资源池中可占用的资源。
其中，所述资源池中包括SL空口在进行通信时，可占用的资源的集合。在一种可行的实现方式中，该资源的集合通常为时域上的多个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号以及频域上多个连续的物理资源块(physical resource block，PRB)对应的集合，其中单个PRB在频域中通常包括12个子载波(即sub-carrier)。
具体的，V2X通信技术为第二种模式定义有感知窗口和选择窗口。在第二种模式中，当终端设备需要在时间单元n传输数据时，终端设备可根据时间单元n确定感知窗口和选择窗口，在感知窗口内，所述终端设备感知V2X网络中各个终端设备的资源占用情况。然后，所述终端设备根据所述感应窗口内的感应结果，确定所述选择窗口 中可占用的资源，并可根据所述可占用的资源进行数据传输，其中，所述选择窗口为所述资源池的子集。
进一步的，设定第一终端设备需要向多个第二终端设备传输数据，在V2X通信技术中，参见图3所示的数据交互示意图，所述第一终端设备会向第二终端设备发送触发信息；所述第二终端设备在接收到触发信息之后，向所述第一终端设备反馈辅助信息，所述辅助信息中包括所述第二终端设备所确定的适合自身应用的资源；所述第一终端设备接收到所述辅助信息之后，会结合所述辅助信息以及自身在感知窗口的感知结果等信息，确定在进行SL空口通信时自身可占用的资源，并可通过该资源向所述第二终端设备进行数据传输。也就是说，在组播场景中，多个第二终端设备向第一终端设备反馈辅助信息。
另外，所述多个第二终端设备向第一终端设备反馈辅助信息时，所述辅助信息所占用的资源块通常由第二终端设备自身确定。这种情况下，不同的第二终端设备反馈的辅助信息之间往往存在干扰，从而导致第一终端设备无法获取正确的辅助信息。
进一步的，第一终端设备需要根据所述辅助信息确定自身进行数据传输的资源，当第一终端设备无法获取正确的辅助信息时，相应的，所述第一终端设备通过所述辅助信息为自身确定资源的准确性降低
为了解决在V2X通信过程中，不同第二终端设备反馈的辅助信息存在干扰，需要确定资源的第一终端设备无法获取正确的辅助信息，进一步导致所述第一终端设备为自身确定资源的准确性降低的问题，本申请实施例提供一种确定辅助信息资源块的方法及装置。
下面将具体结合附图阐述本申请的实施例，以明确本申请提供的确定辅助信息资源块的方法及装置。
在本申请实施例中，提供一种确定辅助信息资源块的方法。参见图4所示的工作流程示意图，所示确定辅助信息资源块的方法包括以下步骤：
步骤S11、第一终端设备确定至少一个第二终端设备发送辅助信息占用的资源块，所述辅助信息用于确定进行数据传输的资源。
其中，所述第一终端设备为向所述至少一个第二终端设备发送数据的终端设备，而所述至少一个第二终端设备为接收所述数据的终端设备，第一终端设备和所述至少一个第二终端设备之间为组播的通信形式。
另外，所述资源块通常为资源池的子集。
步骤S12、所述第一终端设备通过组播发送指示信息，所述指示信息用于指示所述辅助信息占用的资源块。
由于所述第一终端设备需要向所述至少一个第二终端设备发送数据，因此，所述第一终端设备需要确定自身在传输数据时占用的资源，进一步的，所述第一终端设备需要获取所述至少一个第二终端设备的辅助信息，以便通过所述辅助信息以及结合自身感知的资源占用情况，联合确定自身进行数据传输的资源。
这种情况下，所述第一终端设备通过组播发送指示信息。所述至少一个第二终端设备在接收到所述指示信息之后，根据所述指示信息的指示，即可确定自身在发送辅助信息时占用的资源块，并通过该资源块发送辅助信息。所述第一终端设备在接收到 所述辅助信息之后，能够根据所述辅助信息，确定自身进行数据传输时占用的资源块。
在本申请实施例中，提供一种确定辅助信息资源块的方法，应用该方法的网络中包括第一终端设备和至少一个第二终端设备，所述第一终端设备通过组播方式与所述至少一个第二终端设备进行通信。在该方法中，所述第一终端设备确定至少一个第二终端设备发送辅助信息占用的资源块；然后，所述第一终端设备传输指示信息，所述指示信息用于指示所述辅助信息占用的资源块。所述第二终端设备在接收到所述指示信息之后，根据所述指示信息的指示，确定自身在发送辅助信息时占用的资源块，并通过该资源块反馈自身的辅助信息。
当所述至少一个第二终端设备为自身确定辅助信息占用的资源块时，不同第二终端设备的辅助信息在传输过程中往往出现干扰。而通过本申请实施例提供的方案，第一终端设备能够为至少一个第二终端设备确定发送辅助信息时占用的资源块，并且所述至少一个第二终端设备根据所述第一终端设备所确定的资源块发送辅助信息。因此，本申请的方案能够减少不同的第二终端设备反馈的辅助信息之间的干扰，从而能够使第一终端设备获取准确的辅助信息。
进一步的，第一终端设备利用所述辅助信息确定自身进行数据传输时占用的资源，而本申请实施例的方案提高了第一终端设备获取辅助信息的准确性，因此本申请实施例的方案还能够提高第一终端设备为自身确定资源的准确性。
在本申请实施例公开的方案中，第一终端设备确定至少一个第二终端设备发送辅助信息占用的资源块，并向所述至少一个第二终端设备发送用于指示所述辅助信息占用的资源块的指示信息。
其中，所述指示信息与所述第一终端设备向所述至少一个第二终端设备发送的触发信息可为同一信息，即在触发信息中添加用于指示所述辅助信息占用的资源块的内容。这种情况下，参照图3所示的数据交互示意图，所述第一终端设备通过组播向所述至少一个第二终端设备发送指示信息，接收到所述指示信息的第二终端设备根据所述指示信息确定自身发送辅助信息占用的资源块，再通过这一资源块向所述第一终端设备反馈辅助信息。所述第一终端设备在接收到所述辅助信息之后，结合所述辅助信息以及自身感知的资源占用情况，确定自身进行数据传输时占用的资源，并通过该资源向所述至少一个第二终端设备进行数据传输。
另外，所述指示信息与所述第一终端设备向所述至少一个第二终端设备发送的触发信息可为不同的信息。这种情况下，所述第一终端设备可同时向所述至少一个第二终端设备发送所述指示信息与所述触发信息，或者，所述第一终端设备在一段时间范围内先后发送所述指示信息与所述触发信息，该时间范围可由所述第一终端设备确定，并且所述指示信息与所述触发信息的发送时间先后顺序不受限制。并且，所述第二终端设备根据所述指示信息确定自身发送辅助信息的资源块，并在接收到触发信息之后，通过确定的资源块发送辅助信息。
另外，在本申请实施例中，所述资源块可以表达为多种类型，例如可以为资源块(resource block，RB)、资源单元(resource element，RE)或物理资源块(Physical RB，PRB)等，本申请对此不做限定。
在本申请实施例中，所述第一终端设备确定至少一个第二终端设备发送辅助信息 占用的资源块，该操作可包括以下步骤：
所述第一终端设备根据预设规则，在P个资源块中确定所述至少一个第二终端设备发送辅助信息占用的资源块，其中P为所述第二终端设备的数量，并且P为正整数，所述P个资源块包含在资源池确定的资源集合中。
也就是说，在本申请实施例中，当第二终端设备的数量为P时，所述第一终端设备确定P个资源块，其中，每一个资源块用于满足一条辅助信息的发送需求。并且，所述第一终端设备根据预设规则，将所述P个资源块分别分配至P个第二终端设备，即所述第一终端设备为每一个第二终端设备分配一个辅助信息占用的资源块。
其中，所述P个资源块中的每个资源块包括的子信道的数量不小于所述辅助信息占用的子信道的数量，所述P个资源块中不同的资源块包括的子信道不同。
由于每一个资源块满足一条辅助信息的发送需求，因此，每个资源块包括的子信道的数量不小于所述辅助信息占用的子信道的数量。例如，如果一条辅助信息占用2个子信道的长度，则每个资源块中包括的子信道不少于2个。
另外，所述P个资源块中不同的资源块包括的子信道不同，指的是所述P个资源块中不同的资源块在频域上没有重合的子信道，即所述P个资源块不存在重合的现象。
一个第二终端设备反馈的辅助信息占用的资源块往往包括多个子信道。当第二终端设备确定自身反馈的辅助信息所占用的资源块时，多个第二终端设备在反馈辅助信息时，所占用的资源块包括的子信道可能存在重合，从而导致不同的第二终端设备反馈的辅助信息之间存在干扰。
为了明确该干扰产生的原因，本申请提供一个示例。在该示例中，参见图5所示的一个时间单元的示意图，该时间单元包括8个子信道，可记为N subCH＝8，其中N subCH表示一个时间单元所包括的子信道的数量。并且，在该示例中，假定每一辅助信息占据L subCH个子信道，且L subCH＝2，即每一辅助信息占据某一时间单元中2个子信道的资源。这种情况下，一个时间单元最多可由4个第二终端设备的辅助信息占用。
但是，不同终端设备的辅助信息占用的资源块可能存在重合。在该示例中，参见图5，有五个第二终端设备在反馈辅助信息时占用该时间单元，这五个第二终端设备分别为设备A、设备B、设备C、设备D和设备E，其中，设备A占用的子信道分别为子信道0和子信道1，设备B占用的子信道分别为子信道2和子信道3，设备C占用的子信道分别为子信道4和子信道5，设备D占用的子信道分别为子信道5和子信道6，而设备E占用的子信道分别为子信道6和子信道7。也就是说，设备C和设备D共同占用了子信道5，设备D和设备E共同占用了子信道6。因此，设备C和设备D的辅助信息之间会由于子信道的重合出现干扰，以及设备D和设备E的辅助信息之间也会由于子信道的重合出现干扰。
当不同的终端设备反馈的辅助信息之间存在干扰时，将导致第一终端设备无法获取准确的辅助信息。进一步的，第一终端设备需要利用所述辅助信息，以及结合自身感知的资源占用情况，联合确定自身可占用的资源，因此，当所述第一终端设备无法获取准确的辅助信息时，则所述第一终端设备为自身确定可占用的资源的准确性降低。
也就是说，在V2X通信过程中，不同第二终端设备反馈的辅助信息之间往往存在干扰，而该干扰通常由辅助信息占用的资源块存在重合所导致。
因此，在本申请实施例中，第一终端设备确定的所述P个资源块中不同的资源块包括的子信道不同，即所述P个资源块之间不存在重合现象。
示例性的，参见图6(a)，在图6(a)中所示的一个时间单元占用8个子信道的长度，而一个辅助信息占用2个子信道的长度，为了保障各个资源块之间不存在重合，则该时间单元最多可划分为4个资源块，每一个资源块用于发送一条辅助信息。
在另一个示例中，参见图6(b)，该示意图表示一个时间单元占用8个子信道，而一个辅助信息占用4个子信道，为了保障各个资源块之间不存在重合，则该时间单元最多可划分为2个资源块，每一个资源块用于发送一条辅助信息。
这种情况下，由于第一终端设备为不同的第二终端设备所确定的资源块之间不存在重合，因此，所述第二终端设备在通过该资源块反馈辅助信息时，辅助信息之间不存在资源块重合所导致的干扰，从而解决了不同终端设备反馈辅助信息时，占用的资源之间存在重合所导致的干扰问题，即本申请实施例的方案能够使第一终端设备获取准确的辅助信息。
另外，由于本申请实施例的方案使第一终端设备能够获取准确的辅助信息，相应的还能够提高所述第一终端设备为自身确定可占用的资源的准确性。
进一步的，在本申请实施例中，参见图7所示的工作流程示意图，还包括以下步骤：
步骤S21、所述第一终端设备确定在感知窗口内感知到的资源的占用情况。
这一步骤中，所述第一终端设备通过在感知窗口内感知各资源是否被占用，或者是否被预约占用等。
步骤S22、所述第一终端设备根据所述资源的占用情况，确定选择窗口内可占用的目标资源。
其中，所述选择窗口为资源池的子集。
在本申请实施例中，网络设备会为V2X网络内各个终端设备配置资源池，所述第一终端设备与第二终端设备进行通信时，从所述资源池中选择可占用的资源，并通过选择的资源进行通信。这种情况下，所述第二终端设备发送辅助信息时所占用的资源，也为所述资源池中包含的资源。其中，网络设备可根据Mode 2模式的定义配置所述资源池。
其中，在确定所述选择窗口内可占用的目标资源时，通常排除所述选择窗口内的部分资源，剩余的资源即为所述目标资源。被排除的所述资源通常包括所述V2X网络中各个终端设备占用的资源，以及各个终端设备预约占用的资源，或者，所述部分资源还可以包括在感知窗口内未感应到的资源。进一步的，被排除的所述部分资源还可以包括由于其他原因，导致不可占用的资源，本申请实施例对此不做限定。
在V2X通信技术的Mode 2模式中，定义了感知窗口与选择窗口的概念。其中，当所述第一终端设备在时间单元n确定需要进行数据传输时，所述第一终端设备根据时间单元n确定相应的感知窗口与选择窗口，并根据所述感知窗口与选择窗口确定所述目标资源。
具体的，根据Mode 2模式的定义，当所述第一终端设备在时间单元n确定进行数据传输时，所述感知窗口可设置为[n–T 0,n–T proc,0]，并且所述选择窗口可设置为 [n+T 1,n+T 2]。
其中，T 0通常根据第一终端设备的高层参数确定，所述高层参数通常包括所述资源池的标识、本次进行数据传输的优先级和传输一次数据所占用的子信道的个数等；T proc,0通常根据V2X通信的相关标准确定，或者根据第一终端设备的能力确定，或者根据所述第一终端设备的高层参数确定。
另外，所述选择窗口中的T 1和T 2通常根据所述第一终端设备的高层参数确定，或者由第一终端设备根据其他方式确定。
确定所述感知窗口之后，所述第一终端设备在所述感知窗口[n–T 0,n–T proc,0]内感知V2X网络内各个终端设备对资源的占用情况。然后，所述第一终端设备根据在感应窗口的感应结果，确定所述选择窗口[n+T 1,n+T 2]内的可占用的目标资源。
步骤S23、所述第一终端设备从所述目标资源中确定参考信号接收功率RSRP最小的时间单元，所述时间单元为所述资源集合。
其中，所述时间单元为时隙或者微时隙，或者，所述时间单元还可以为其他形式，本申请实施例对此不作限定。另外，当一个时间单元包括多个RB时，这一时间单元的RSRP指的是所述时间单元内包括的多个RB的RSRP的平均值。
在上述实现方式中，所述资源集合包括至少一个RSRP最小的时间单元，所述至少一个RSRP最小的时间单元包括的可用于发送辅助信息的资源块的数量不少于所述第二终端设备的数量P，并且每个可由辅助信息占用的资源块包括的子信道的数量不少于所述辅助信息包括的子信道的数量。
例如，所述时间单元如图6(a)所示，即一个时间单元包括8个子信道，而一条辅助信息占用2个子信道，这种情况下，如果所述第二终端设备的数量大于4，则所述资源集合中包括两个或更多个的时间单元；如果所述第二终端设备的数量小于或等于4，则所述资源集合中可只包括一个时间单元。
其中，所述第一终端设备在感应窗口感应资源的占用情况时，可确定各个时间单元的RSRP。因此，在上述步骤中，所述第一终端设备可确定所述目标资源中各个时间单元的RSRP的大小的排序，从而从中选择RSRP最小的时间单元。
如果检测到某一个时间单元的RSRP较小，通过该时间单元传输信息，则该信息可受到的干扰较小。因此，在本申请实施例中，从目标资源中选择RSRP最小的时间单元作为资源集合，有助于保障发送辅助信息的可靠性。
或者，所述第一终端设备还可通过其他方式确定资源集合。当通过时域位置确定所述资源集合时，参见图8所示的工作流程示意图，本申请实施例还包括以下步骤：
步骤S31、所述第一终端设备确定在感知窗口内感知到的资源的占用情况；
步骤S32、所述第一终端设备根据所述资源的占用情况，确定选择窗口内可占用的目标资源。
其中，步骤S31至步骤S32的执行过程与步骤S21至步骤S22的执行过程相同，可相互参照，此处不再赘述。
步骤S33、所述第一终端设备从所述目标资源中确定时域位置最靠前的时间单元，所述时间单元为所述资源集合。
在上述实现方式中，所述资源集合中包括的时间单元的时域位置较靠前，则第二 终端设备在发送辅助信息时，占用的资源块的时域位置较靠前，从而能够减少辅助信息的发送时延。
或者，所述第一终端设备可在所述目标资源中，任意选择至少一个时间单元作为所述资源集合，该至少一个时间单元中包括的资源块的数量不少于第二终端设备的数量P，并且，每个资源块包括的子信道的数量不小于所述辅助信息占用的子信道的数量。
当然，所述第一终端设备还可通过其他方式确定所述资源集合，本申请实施例对此不作限定。
另外，所述资源集合中最少包括一个时间单元。当一个时间单元不能满足第二终端设备发送辅助信息的需求时，所述资源集合中还可包括更多数量的时间单元。
其中，当所述资源集合中包括一个时间单元时，所述第一终端设备确定的所述资源集合的示意图可如图9(a)所示。图9(a)表示在时间单元n确定需要传输数据，通过感知窗口[n–T 0,n–T proc,0]确定资源的占用情况，并根据感知窗口的感知结果，确定选择窗口内可占用的目标资源，再从所述目标资源中选择资源集合。在该示例中，所述资源集合中包括一个时间单元，在图9(a)中，这一个时间单元为时间单元m。在确定时间单元m之后，所述第一终端设备可将时间单元m划分为P个资源块，再从所述P个资源块确定各个第二终端设备占用的资源块。
另外，当所述资源集合中包括两个或更多的时间单元时，第一终端设备确定的所述资源集合的示意图可如图9(b)所示。图9(b)表示从所述目标资源中，选择了四个时间单元，所述四个时间单元在所述选择窗口中通过长方形的阴影表示，并且由于不同的时间单元中包含的可占用的子信道的数量不同，则长方形的阴影的长度不同。在确定所述四个时间单元之后，所述第一终端设备可将这四个时间单元划分为P个资源块，再从所述P个资源块确定各个第二终端设备占用的资源块。
在本申请实施例中，所述第一终端设备根据预设规则，在P个资源块中确定所述至少一个第二终端设备发送辅助信息占用的资源块。
其中，所述预设规则可为多种形式。在其中一种形式中，所述预设规则包括所述至少一个第二终端设备的标识号的变化规则，其中，所述变化规则包括所述至少一个第二终端设备的标识号由小变大或由大变小。
这种情况下，所述第一终端设备根据预设规则，在P个资源块中确定所述至少一个第二终端设备发送辅助信息占用的资源块，包括：
所述第一终端设备根据所述P个资源块的位置信息，确定所述P个资源块的排序；以及，所述第一终端设备根据所述P个资源块的排序和所述预设规则，在所述P个资源块中确定所述至少一个第二终端设备发送辅助信息占用的资源块。
在这一实现方式中，所述第一终端设备根据所述P个资源块的位置信息对所述P个资源块进行排序，然后在对所述P个资源块排序之后，所述第一终端设备可根据各个第二终端设备的标识号由小到大的顺序或由大到小的顺序，按照资源块的排序依次为第二终端设备确定相应的资源块。
另外，所述第一终端设备根据所述P个资源块的位置信息，确定所述P个资源块的排序时，可确定时域位置较早的资源块的排序位置较靠前，以及确定频域位置靠前 的资源块的排序位置较靠前。
例如，当所述P个资源块如图6(a)所示，则该P个资源块的排序依次为：包括子信道0和子信道1的资源块、包括子信道2和子信道3的资源块、包括子信道4和子信道5的资源块和包括子信道6和子信道7的资源块。
当然，所述第一终端设备还可以确定时域位置较早的资源块的排序位置较靠后，以及确定频域位置靠前的资源块的排序位置较靠后，本申请实施例对此不做限定。
在另外一种形式中，所述预设规则包括所述P个资源块的资源块号与第二终端设备的标识号之间的映射关系。
这种情况下，所述第一终端设备根据预设规则，在P个资源块中确定所述至少一个第二终端设备发送辅助信息占用的资源块，包括以下步骤：
所述第一终端设备根据所述P个资源块的位置信息，确定所述P个资源块的资源块号；
所述第一终端设备根据所述P个资源块的资源块号和所述预设规则，在所述P个资源块中确定所述至少一个第二终端设备发送辅助信息占用的资源块。
示例性的，所述P个资源块的资源块号包括：RB1、RB2和RB3，所述至少一个第二终端设备的标识号包括：00、01和10，而该映射关系表示资源块RB1与第二终端设备00相对应，资源块RB2与第二终端设备01相对应，以及资源块RB3与第二终端设备10相对应，则第一终端设备确定资源块RB1为所述第二终端设备00发送辅助信息占用的资源块，资源块RB2为所述第二终端设备01发送辅助信息占用的资源块，以及资源块RB3为所述第二终端设备10发送辅助信息占用的资源块。
在本申请实施例中，可预先设定所述P个资源块的资源块号与第二终端设备的标识号之间的映射关系，并将该映射关系存储至V2X网络中的各个终端设备中。
另外，所述第一终端设备根据所述P个资源块的位置信息，确定所述P个资源块的资源块号，这一步骤中，通常确定时域位置较早的资源块的资源块号较小，以及确定频域位置靠前的资源块的资源块号较小。
例如，当所述P个资源块如图6(a)所示，则该P个资源块的资源块号的大小排序依次为：包括子信道0和子信道1的资源块、包括子信道2和子信道3的资源块、包括子信道4和子信道5的资源块和包括子信道6和子信道7的资源块，并据此确定各个资源块的资源块号。
当然，还可以确定时域位置较早的资源块的资源块号较小，以及确定频域位置靠前的资源块的资源块号较小，本申请实施例对此不做限定。
在确定各个第二终端设备发送辅助信息占用的资源块之后，第一终端设备会传输指示信息。其中，所述指示信息包括：所述P个资源块的位置信息。
通过所述指示信息，所述至少一个第二终端设备可确定所述P个资源块的位置信息。另外，所述至少一个第二终端设备可预先通过与所述第一终端设备的协议，确定所述预设规则，这种情况下，所述至少一个第二终端设备根据所述预设规则，可确定所述P个资源块中，自身在发送辅助信息时占用的资源块。
进一步的，当所述至少一个第二终端设备并未确定所述第一终端设备采用的所述预设规则时，所述指示信息还包括所述预设规则的索引编号。这种情况下，在接收到 所述指示信息之后，所述至少一个第二终端设备科根据所述预设规则的索引编号确定所述预设规则，并根据所述预设规则确定所述P个资源块中，自身在发送辅助信息时占用的资源块。
或者，所述指示信息不仅包括所述P个资源块的位置信息，并且还包括所述P个资源块的资源块号，以及所述P个资源块中每个资源块的资源块号对应的第二终端设备的标识号。
这种情况下，第二终端设备在接收到所述指示信息之后，根据自身的标识号，确定与自身的标识号相对应的资源块号，再根据该资源块号对应的资源块的位置信息，确定自身在发送辅助信息时占用的资源块。
当然，所述指示信息还可以包括其他信息，本申请实施例对此不做限定。
在所述指示信息中，包括P个资源块的位置信息，其中，所述P个资源块的位置信息包括以下一种：所述P个资源块的时域位置和频域位置；以及比特地图，所述比特地图用于指示所述P个资源块是否可用。

在这一种设计方式中，通过比特地图指示各个资源块是否可用，从而无需在指示信息中添加各个资源块的时域位置和频域位置，减少了指示信息中包含的字符量，节省了传输指示信息所需的网络资源。其中，P的值越大，即第二终端设备的数量越多时，所减少的指示信息中的字符量越多。
进一步的，有些情况下，所述资源集合为一个时间单元，即一个时间单元包括的资源块可满足所述至少一个第二终端设备发送辅助信息的需求。这种情况下，所述P个资源块的时域位置为所述一个时间单元的编号。通过所述时间单元的编号，所述至少一个第二终端设备可确定所述P个资源块所在的时间单元，进而通过所述P个资源块所在的时间单元的时域位置确定所述P个资源块的时域位置。并且，所述P个资源 块的时域位置通过一个时间单元的编号表征，能够有效减少指示信息中包括的字符量，并且能够节省传输指示信息所需的网络资源。
