背景技术
长期演进(Long Term Evolution，LTE)Rel-14的车辆到万物(Vehicle-to-Everything，V2X)技术中，车辆到车辆(Vehicle to Vehicle，V2V)发送数据占用的资源在时间上的粒度是一个LTE传统子帧(normal subframe)，一个子帧为1ms。LTE-based V2V技术是基于LTE设备到设备(Device to Device，D2D)方式上的改进，其中，调度分配(Scheduling Assignment，SA)信息通过物理侧链控制信道(Physical Sidelink Control Channel，PSCCH)，数据(Data)是通过物理侧链路共享信道(Physical Sidelink Shared Channel，PSSCH)进行传输。接收端通过检测控制信道中携带的SA信息，根据接收到的SA信息接收数据。

具体实施方式
在LTE Rel-14V2V技术中，同一个UE的SA信息以及SA信息关联的数据在同一个子帧中发送，SA信息和SA信息关联的数据可通过以下两种频分复用方式传输：方式一、SA信息和SA信息关联的数据在一个子帧中采用邻频的方式传输，该子帧的时频资源配置 如图2a所示，一个SA信息占用的频率资源与该SA关联的数据所占用的频率资源是相邻的；方式二、SA信息和SA信息关联的数据在一个子帧中采用非邻频的方式传输，该子帧的时频资源配置如图2b所示，一个SA信息占用的频域资源位置和该SA关联的数据占用的频域资源的起点位置对应。在这两种方式中，一个SA信息在频域上固定占用2个物理资源块(Physical Resource Block，PRB)，且一个SA信息可以调度多个子信道进行数据传输。
LTE based V2V技术中，车辆与车辆之间进行数据传输时通过以下两种方式选择资源：方式一、UE自发选择资源，如图1a所示，UE根据资源占用情况，从UE中预先配置的V2X资源池(resource pool)或基站配置的V2X资源池中自主选择资源；方式二、基站辅助选择资源，如图1b所示，当UE处于网络覆盖范围内时，基站通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)或增强物理下行控制信道(Enhanced Physical Downlink Control Channel，EPDCCH)发送V2V准许(grant)消息，对V2V通信进行资源调度，其中，V2V grant消息用于指示发送数据的UE发送SA信息和数据的时频资源。
并且，一个数据最多可以传输两次(数据传输次数是可配置的)，如果一个数据传输两次，那么第一次为该数据的初传，第二次为该数据的重传，且初传时该数据关联的SA信息和重传时该数据关联的SA信息中都携带这两次传输的数据的资源指示信息，如图3所示。如果初传时数据关联的SA信息接收错误，而重传时数据关联的SA信息接收正确，则UE不需要根据重传时数据关联的SA的信息中的初传时数据的资源指示信息，对初传的数据进行检测。
为了满足V2X技术的演进要求，本申请实施例新定义了一种SA信息以及用于传输SA信息的物理层格式。为了与原有的SA信息进行区分，在本申请实施例中，将新定义的SA信息称为第一类SA信息，将原有的SA信息称为第二类SA信息。第一类SA信息占用的时域长度小于一个传统子帧的时域长度，第二类SA信息占用的时域长度为一个传统子帧的时域长度。支持第一类SA信息检测的终端或支持第二类SA信息采用多天线方式传输的终端称为新终端(new UE)，不支持第一类SA信息检测但支持第二类SA信息的终端称为传统终端(legacy UE)。
本申请实施例中第一终端(即new UE)向其他终端发送数据的流程如图4所示，包括以下步骤：
步骤401：第一终端从调度分配SA信息的时频资源集合中，选择至少一个第一类SA信息的时频资源。
实施中，第一终端中预先配置有SA信息的时频资源集合，或者，第一终端在发送至少一个第一类SA信息之前，接收基站发送的SA信息的时频资源集合，其中，该SA信息的时频资源集合中包括多个第一类SA信息的时频资源。
步骤402：第一终端按照第一物理层格式在该至少一个第一类SA信息的时频资源上发送至少一个第一类SA信息，并根据该至少一个第一类SA信息的指示，按照第二物理层格式发送该至少一个第一类SA信息关联的数据，其中，第一类SA信息中至少包含该第一类SA信息关联的数据的时频资源指示信息。
实施中，第一终端可通过广播、组播等方式将第一类SA信息和第一类SA信息关联的数据同时发送给多个终端。
具体地，一个第一类SA信息在时域上占用一个时隙(slot)，或者，一个第一类SA信息在时域上占用多个符号。当一个第一类SA信息在时域上占用一个时隙时，在一个传统normal子帧中，第一类SA信息以及第一类SA信息关联的数据占用的时频资源如图5所示。一个normal子帧所在的资源池(resource pool)中一个子信道(subchannel)包括两个第一类SA信息和这两个第一类SA信息所关联的数据，一个第一类SA信息和该第一类SA信息所关联的数据采用频分复用的方式传输。当一个第一类SA信息在时域上占用多个符号时，在一个normal子帧中，第一类SA信息以及第一类SA信息关联的数据占用的时频资源如图6所示，normal子帧所在的资源池的一个子信道中包括四个第一类SA信息和这四个第一类SA信息所关联的数据，一个第一类SA信息和该第一类SA信息所关联的数据采用频分复用的方式传输。可选地，上述符号可以是正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号。
实施中，第一终端传输的第一类SA信息占用的时域长度小于一个normal子帧占用的时域长度，减少了数据传输的时延。
实施中，第一物理层格式与第二物理层格式可以相同，也可以不同。第一物理层格式与第二物理层格式相同时，第一物理层格式中一个第一类SA信息占用的时域长度与第二物理层格式中该第一类SA信息关联的数据占用的时域长度相同，第一物理层格式中一个第一类SA信息与第二物理层格式中该第一类SA信息关联的数据采用相同的传输模式。
第一物理层格式与第二物理层格式不同时，第一物理层格式中一个第一类SA信息占用的时域长度与第二物理层格式中该第一类SA信息关联的数据占用的时域长度相同，第一物理层格式中一个第一类SA信息与第二物理层格式中该第一类SA信息关联的数据采用不同的传输模式。
其中，第一类SA信息的传输模式和第一类SA信息关联的数据的传输模式包括单天线传输模式或多天线传输模式，多天线传输模式包括多天线多端口的发射分集模式，多天线单端口的发射分集模式或多天线多端口的空间复用模式等。具体地，第一物理层格式与第二物理层格式不同时，若第一物理层格式中一个第一类SA信息采用单天线传输模式，则第二物理层格式中一个该第一类SA信息关联的数据采用多天线传输模式，若第一物理层格式中一个第一类SA信息采用多天线传输模式，则第二物理层格式中一个该第一类SA 信息关联的数据采用单天线传输模式。
具体地，第一类SA信息包括以下信息中的一个或任意组合：该第一类SA信息关联的数据的调制与编码策略MCS指示信息，解调参考信号(Demodulation Reference Signal，DMRS)序列的指示信息数据传输模式的指示信息，冗余版本指示信息，资源预约周期指示周期以及业务优先级指示信息。DMRS序列的指示信息包括DMRS初始化标识(Identification，ID)和/或DMRS循环移位指示信息。
可选地，第一终端在发送第一类SA信息和该第一类SA信息关联的数据时，还从SA信息的时频资源集合中，选择至少一个第二类SA信息的时频资源，在该至少一个第二类SA资源上按照第三物理格式发送至少一个第二类SA信息。其中，第三物层理格式中一个第二类SA信息占用一个子帧的时域长度，该第二类SA信息采用单天线传输模式，使得新终端和传统终端均能够检测第二类SA信息。若检测到第二类SA信息的终端为传统终端，则传统终端能够根据该第二类SA信息确定该第二类SA信息指示的数据的时频资源被第一终端占用，使得传统终端在发送数据时能够避开第一终端所占用的时频资源，避免发生资源冲突。
其中，第二类SA信息主要包括以下信息：(1)优先级(8种)，占用3比特(bits)；(2)资源预约周期，表示当前第二类SA指示的资源会在下一个预约周期时继续使用，占用4bits；(3)另一次传输的频域资源位置(起点或长度)，用于指示当前第二类SA信息指示的初传和重传的数据占用的频率资源，占用的比特数小于等于8bits；(4)初传/重传的时间间隔，占用4bits，若只有一次传输，该信息比特位全部为0；(5)调制与编码策略，占用5bits；(6)重传指示，用于指示与当前第一类SA信息关联的数据是初传还是重传，占用1bit；(7)预留/填充padding比特，占用的比特数大于等于7bits。
可选地，第二类SA信息中包括指示信息，该指示信息用于指示是否需要根据第二物理层格式对该第二类SA信息指示的数据进行检测，使得新终端接收到第二类SA信息后，可以不对该第二类SA信息所指示的数据进行检测，降低新终端的处理复杂度。一个具体的实现方式中，通过第二类SA信息中预留比特中的一个比特指示接收该第二类SA信息的终端是否需要根据第三物理层格式对该第二类SA信息指示的数据进行检测，若该比特置为0，则表示接收该第二类SA信息的终端需要按照第三物理层格式对该第二类SA信息指示的数据进行检测，若该比特置为1，则表示接收该第二类SA信息的终端不需要按照第三物理层格式对该第二类SA信息指示的数据进行检测。
可选地，一个第二类SA信息所指示的数据的时频资源中，包括至少一个第一类SA信息所占用的时频资源和至少一个第一类SA信息关联的数据所占用的时频资源。一个具体的实现方式中，当一个第二类SA信息所指示的数据的时频资源中包括一个第一类SA信息所占用的时频资源和该第一类SA信息关联的数据所占用的时频资源时，一个normal 子帧的时频资源配置如图7所示，该第一类SA信息和该第一类SA信息关联的数据在时域上占用一个时隙。
可选地，一个第一类SA信息所占用的频率资源为一个第二类SA信息指示的数据的频率资源中频率小于第一阈值的区域，或为该第二类SA信息指示的数据的频率资源中频率大于第二阈值的区域，第二阈值大于第一阈值。以第一类SA信息和第一类SA信息关联的数据在时域上占用一个时隙为例，当一个第一类SA信息所占用的频率资源为一个第二类SA信息指示的数据的频率资源中频率小于第一阈值的区域时，一个normal子帧中第一类SA信息、第一类SA信息关联的数据以及第二类SA信息的时频资源配置如图8a所示，当一个第一类SA信息所占用的频率资源为一个第二类SA信息指示的数据的频率资源中频率大于第二阈值的区域时，一个normal子帧中第一类SA信息、第一类SA信息关联的数据以及第二类SA信息的时频资源配置如图8b所示。
可选地，若一个第二类SA信息所指示的数据的时频资源中包括多个第一类SA信息所占用的时频资源和该多个第一类SA信息关联的数据所占用的时频资源，则该多个第一类SA信息所占用的时频资源和该多个第一类SA信息关联的数据所占用的时频资源用于传输同一个终端的数据，或者不同终端的数据。
具体地，若一个第二类SA信息所指示的数据的时频资源中包括的多个第一类SA信息所占用的时频资源和该多个第一类SA信息关联的数据所占用的时频资源用于传输同一个终端的数据，该多个第一类SA信息所占用的时频资源和该多个第一类SA信息关联的数据所占用的时频资源用于传输相同的数据或不同的数据，这两种方式可以由基站通过网络的配置、终端的预配置、或者通过一个群group内部的终端确定，此时，一个normal子帧的结构如图9所示，其中一个第一类SA信息和该第一类SA信息占用一个时隙。若该多个第一类SA信息所占用的时频资源和该多个第一类SA信息关联的数据所占用的时频资源用于传输同一个终端的同一个数据，则一个该多个第一类SA信息关联的数据之间相当于初传和重传的关系，能够提高数据传输的可靠性，并且接收该多个第一类SA信息和该多个第一类SA信息关联的数据的终端可以对该多个第一类SA信息和该多个第一类SA信息关联的数据进行混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)合并处理，减少了重传次数，进而减少了时延。
若一个第二类SA信息所指示的数据的时频资源中包括的多个第一类SA信息所占用的时频资源和该多个第一类SA信息关联的数据所占用的时频资源用于传输不同终端的数据，由于在一个normal子帧中，发送第二类SA信息的终端无法接收该子帧中其他终端发送的第一类SA信息和该第一类SA信息关联的数据，其中，其他终端发送的第一类SA信息和该第一类SA信息关联的数据的目标终端是发送第二类SA信息的终端，因此需要通过配对子帧进行数据传输，重传其他终端发送的数据，使得发送第二类SA信息的终端能 够接收到该子帧中其他终端发送的第一类SA信息和该第一类SA信息关联的数据。其中，在配对的子帧中，第二类SA信息的发送终端不同。
一个具体的实现方式中，当一个第二类SA信息所指示的数据的时频资源中包括的两个第一类SA信息所占用的时频资源和这两个第一类SA信息关联的数据所占用的时频资源时，配对子帧的结构如图10所示，第一子帧中第二类SA信息，以及密集的黑点填充区域表示的第一类SA信息和第一类SA信息关联的数据是UE1发送的，白色填充区域表示的第一类SA信息和第一类SA信息关联的数据是UE2发送的。当UE2发送的第一类SA信息和第一类SA信息关联的数据的目标终端是UE1时，UE1无法通过第一子帧接收UE2发送的数据，因此UE2还需要向UE1发送与第一子帧配对的第二子帧，重传U2发送给UE1的数据，第二子帧中第二类SA信息，以及白色区域表示的第一类SA信息和第一类SA信息关联的数据是UE2发送的，密集的黑点填充区域表示的是UE1发送的第一类SA信息和第一类SA信息关联的数据，第一子帧和第二子帧中UE2发送的第一类SA信息和第一类SA信息关联的数据相同。
实施中，在同一个子帧中，第二类SA信息、第一类SA信息和第一类SA信息关联的数据根据第二类SA信息指示的数据的时频资源与该第二类SA信息所占用的时频资源是否相邻，分为采用邻频传输方式和非邻频传输方式。具体地，当一个第一类SA信息和该第一类SA信息关联的数据占用一个时隙时，采用邻频方式传输的子帧的结构如图11a所示，一个子信道中包括一个第二类SA信息、两个第一类SA信息以及这两个第一类SA信息指示的数据，这两个第一类SA信息以及这两个第一类SA信息指示的数据占用该第二类SA信息所指示的数据的时频资源，一个第二类SA信息占用的时频资源与该第二类SA信息所指示的数据的时频资源相邻。采用非邻频方式传输的子帧的结构如图11b所示，一个子信道中包括一个第二类SA信息对应一个子信道，一个子信道中包括两个第一类SA信息以及这两个第一类SA信息指示的数据，这两个第一类SA信息以及这两个第一类SA信息指示的数据占用该第二类SA信息所指示的数据的时频资源(该第二类SA信息对应的子信道)，一个第二类SA信息占用的时频资源与该第二类SA信息所指示的数据的时频资源不相邻。
本申请提供的另一个实施例中，第一终端从调度分配SA信息的时频资源集合中，选择至少一个第二类SA信息的时频资源，终端采用多天线传输模式在至少一个第二类SA信息的时频资源上发送至少一个第二类SA信息，并根据至少一个第二类SA信息的指示，采用多天线传输模式或单天线传输模式发送第一类SA信息关联的数据，用于传输至少一个第二类SA信息和至少一个第二类SA信息的子帧的结构如图12所示。
第二终端接收第一终端发送的至少一个第一类SA信息和至少一个第一类SA信息关联的数据的流程如图13所示，包括以下步骤：
