在对本发明实施例进行详细描述之前，首先对车联网***进行简要说明。
车联网***是基于终端到终端(Device to Device，D2D)通信的一种侧行链路(Side Link，SL)传输技术，与传统的LTE***中通信数据通过基站接收或者发送的方式不同，车联网***中通信数据采用终端到终端直接通信的方式，因此具有更高的频谱效率以及更低的传输时延。
在3GPP Rel-14中对V2X进行了标准化，定义了两种传输模式：模式3和模式4。
针对模式3，数据传输的流程，如图2所示，车载终端的侧行链路传输资源是由基站分配的，车载终端根据基站分配的资源在侧行链路上进行数据的发送；基站可以为终端分配单次传输的资源，也可以为终端分配半静态传输的资源。
针对模式4，数据传输的流程，如图3所示，车载终端采用侦听(sensing)和预留(reservation)的传输方式。车载终端在资源池中通过侦听的方式获取可用的传输资源集合，终端从该集合中随机选取一个资源进行侧行链路数据的传输。由于车联网***中的业务具有周期性特征，因此终端通常采用半静态传输的方式，即终端选取一个传输资源后，就会在多个传输周期中持续的使用该资源，从而降低资源重选以及资源冲突的概率。终端会在本次传输的控制信息中携带预留下次传输资源的信息，从而使得其他终端可以通过检测该用户的控制信息判断这块资源是否被该用户预留和使用，达到降低资源冲突的目的。
在NR-V2X中，需要支持自动驾驶，因此对车辆之间数据交互提出了更高的要求，如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在NR-V2X中，还需要支持多种传输方式，如单播(unicast)、组播(groupcast)、广播(broadcast)。在单播传输时需要数据接收终端设备向数据发送终端设备发送的反馈信息，如确认/不确认(ACK/NACK)信息、信道状态指示(Channel State Indicator，CSI)信息等，数据发送终端设备根据数据接收终端设备的反馈信息可以调整调制与编码策略(Modulation and Coding Scheme，MCS)等级以及判断是否需要进行重传等。
在NR-V2X中，侧行链路的传输资源可以是由网络设备分配的；在侧行链路上，数据接收终端设备向数据发送终端设备发送了反馈信息，反馈信息包括：ACK/NACK、CQI、信道状态信息(Channel State Information，CSI)、功率调整信息等，发送终端设备需要将所述反馈信息发送给网络设备，从而辅助网络设备的资源调度以及传输参数配置。网络设备根据数据发送终端设备反馈的信息，判断侧行链路上的数据是否被数据接收终端设备正确接收，从而为数据发送终端设备分配资源用于新数据传输或者重传，或者，数据发送终端设备将CSI/CQI等信息发送给网络设备，辅助网络设备进行传输参数配置，例如，配置侧行链路使用的MCS等。但是，数据发送终端设备如何将反馈信息发送给网络设备，目前尚无有效解决方案。
基于上述问题，本发明实施例提供的应用于终端设备的信息传输方法的可选处理流程，如图4所示，包括以下步骤：
步骤S201，第一终端设备向网络设备发送第一指示信息。
在一些实施例中，所述第一指示信息携带第一信息，所述第一信息至 少包括下述中的至少一种：
1)ACK/NACK信息，用于指示所述第一终端设备向第二终端设备发送的侧行数据是否被所述第二终端设备正确接收；
2)波束索引信息，用于指示所述第一终端设备向所述第二终端设备发送侧行数据使用的波束；
3)CQI信息，用于指示所述第一终端设备和所述第二终端设备之间的信道质量；
4)CSI信息，用于指示所述第一终端设备和所述第二终端设备之间的信道状态；
5)预编码矩阵指示(Precoding Matrix Indicator，PMI)信息，用于指示所述第一终端设备向所述第二终端设备发送侧行数据使用的预编码信息；
6)秩指示信息，用于指示所述第一终端设备向所述第二终端设备发送侧行数据使用的秩信息；
7)功率指示信息，用于指示提高或降低功率，或用于指示功率余量信息；
8)候选资源集合，所述候选资源集合是所述第一终端设备在侧行链路上通过侦听获得的可用传输资源集合。举例来说，网络设备为第一终端设备在第一资源池中分配侧行链路传输资源，在网络设备为所述第一终端设备分配传输资源之前，所述第一终端设备在所述第一资源池中通过侦听的方式确定所述候选资源集合，所述候选资源集合中的每一个资源都是可以用于所述第一终端设备传输侧行链路数据的传输资源；例如，所述候选资源集合是在一个资源选择窗内的能量最低的N个传输资源构成的集合。所述第一终端设备将所述候选资源集合发送给网络设备，以辅助网络设备的资源调度。
所述第一终端设备向网络设备发送第一指示信息的具体实现方式至少包括：
所述第一终端设备向所述网络设备发送上行控制信道，所述上行控制信道中携带所述第一指示信息。或者，所述第一终端设备向所述网络设备发送上行数据信道，所述上行数据信道中携带所述第一指示信息。或者，所述第一终端设备向所述网络设备发送上行无线资源控制(Radio Resource Control，RRC)信令，所述RRC信令承载所述第一信息。或者，所述第一终端设备向网络设备发送调度请求(Scheduling Request，SR)，所述SR携带所述第一指示信息。或者，所述第一终端设备向网络设备发送缓冲状态报告(Buffer Status Report，BSR)，所述BSR携带所述第一指示信息。
在所述第一指示信息由所述第一终端设备通过发送上行控制信道发送至所述网络设备时，可以通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)承载所述第一指示信息；并且，不同的PUCCH格式可 以传输的信息的比特数目不同；因此，针对第一指示信息包括的不同内容，可以采用相应的PUCCH格式来承载。
举例来说，如果所述第一指示信息包括的比特数小于或等于2比特，可以通过第一PUCCH格式承载所述第一指示信息；如果所述第一指示信息包括的比特数大于2比特时，可以通过第二PUCCH格式承载所述第一指示信息。
可选的，在所述第一指示信息由所述第一终端设备通过发送上行控制信道发送至所述网络设备时，所述第一终端设备还接收所述网络设备发送的下行控制信息(Downlink Control Information，DCI)，所述下行控制信息用于为所述第一终端设备分配侧行链路传输资源；所述下行控制信息携带第二指示信息，所述第二指示信息用于确定所述上行控制信道的传输资源。
举例来说，网络设备向第一终端设备发送配置信息，所述配置信息用于配置PUCCH的传输资源集合。网络设备通过DCI为第一终端设备分配侧行链路的传输资源，在该DCI中可以携带第二指示信息，所述第二指示信息用于结合上述配置信息确定PUCCH的传输资源。具体的，例如，所述第二指示信息包括一个索引信息，用于在网络配置的多个PUCCH传输资源中确定一个传输资源。或者所述第二指示信息用于指示PUCCH与该DCI的时间间隔，进一步的，可以指示PUCCH的频域资源，因此可以确定传输反馈信息用的PUCCH的传输资源。
上面以配置信息用于配置PUCCH的传输资源集合为例进行说明，在具体实施时，配置信息还可以用于配置PUSCH的传输资源集合。具体的，网络设备通过DCI为第一终端设备分配侧行链路的传输资源，在该DCI中可以携带第二指示信息，所述第二指示信息用于结合上述配置信息确定PUSCH的传输资源。具体的，例如，所述第二指示信息包括一个索引信息，用于在网络配置的多个PUSCH传输资源中确定一个传输资源。或者所述第二指示信息用于指示PUSCH与该DCI的时间间隔，进一步的，可以指示PUSCH的频域资源，因此可以确定传输反馈信息用的PUSCH的传输资源。
可选的，在所述第一指示信息由所述第一终端设备通过发送上行数据信道发送至所述网络设备时，所述第一指示信息通过对所述上行数据信道打孔(puncturing)的方式，承载在所述上行数据信道上。以所述第一指示信息包括ACK/NACK信息为例，可以对需要发送至网络设备的ACK/NACK信息进行编码，编码后的比特对PUSCH信道的资源进行打孔；即用ACK/NACK编码后的符号替代PUSCH的数据符号。
举个例子，在LTE***中，PUSCH的帧结构为在子帧中的第4个和第11个时域符号用于传输解调参考信号(demodulation reference signal，DMRS)，除第4个和第11个时域符号以外的其他时域符号可以用于传输PUSCH。如果网络为第一终端设备分配的用于传输PUSCH的频域资源为4个物理资源块(physical resource block，PRB)，该第一终端设备首先将 PUSCH的数据映射到除了DMRS符号之外的所有传输资源上，然后利用ACK/NACK编码后的符号替换PUSCH的数据符号，即利用ACK/NACK符号对PUSCH数据进行打孔。例如，将编码后的ACK/NACK符号替换掉第一个DMRS时域符号的下一个符号(即第5个时域符号)上的PUSCH数据。
可选的，在所述第一指示信息由所述第一终端设备通过发送上行数据信道发送至所述网络设备时，所述第一指示信息通过速率匹配的方式承载在所述上行数据信道上。
举例来说，终端设备根据参数配置(如MCS等)确定待反馈的信息所占用的资源数量，将编码后的反馈信息映射到相应的传输资源上，将PUSCH的数据和参考信号映射到其他资源上。其中，PUSCH的数据能够使用的资源是网络分配的传输资源去除反馈信息占用的资源以及导频信号等占用的资源之后，所剩余的传输资源。
可选的，在所述第一指示信息由所述第一终端设备通过发送SR发送至所述网络设备时，以第一指示信息为ACK/NACK信息为例，网络设备为第一终端设备配置两套SR的资源，如果第一终端设备在第一套SR的资源上发送SR，则表示第一终端设备发送的是ACK信息；如果第一终端设备在第二套SR的资源上发送SR，则表示第一终端设备发送的是NACK信息。通过上述实施方式，第一终端设备能够隐式的向网络设备发送ACK信息或NACK信息。
在又一实施例中，第一终端设备在执行步骤S201之前，所述方法还包括：
步骤S200，第一终端设备接收第二终端设备发送的第一侧行信道，所述第一侧行信道携带第一指示信息。
其中，所述第一侧行信道可以是PSCCH、PSSCH、或者侧行反馈信道等。
举例来说，第二终端设备接收到第一终端设备发送的侧行链路数据，向所述第一终端设备发送反馈信息，如，ACK/NACK信息，或者CSI/CQI信息等。
在另一实施例中，第一终端设备在执行步骤S201之前，所述方法还包括：
步骤S200’，第一终端设备接收所述第二终端设备发送的第二侧行信道，所述第一终端设备根据所述第二侧行信道获得所述第一指示信息。
其中，所述第一侧行信道可以是用于传输物理侧行控制信道(Physical Sidelink Control Channel，PSCCH)、或者物理侧行共享信道(Physical Sidelink Shared Channel，PSSCH)、或者侧行反馈信道、或者物理侧行发现信道(Physical Sidelink Discovery Channel，PSDCH)、或者参考信号；所述参考信号可以是信道状态指示参考Channel State Information Reference Signal， CSI-RS、或者侦听参考信号(Sounding Reference Signal，SRS)等。
