参见图1，图1是本公开实施例可应用的网络结构示意图，如图1所示， 包括多个终端11和网络设备12，其中，终端11可以是用户终端(User Equipment，UE)或者其他终端设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)、机器人、车载终端、车辆等终端侧设备，需要说明的是，在本公开实施例中并不限定终端的具体类型。终端11之间可以直接通信的直通链路称为Sidelink(翻译为直接通信链路或者旁路，也称为直接通信接口或者直通链路接口)，即终端之间可以通过Sidelink进行直接通信。直接通信的终端可以均是在网的，或者均是脱网的，还可以是部分设备在网，部分设备脱网。网络设备12可以是基站，例如：宏站、长期演进(Long Term Evolution，LTE)演进型基站(evolved node base station，eNB)、第五代(5th generation，5G)NR基站(node base station，NB)等；网络设备也可以是小站，如低功率节点(Low Power Node，LPN)、微微基站(pico)、毫微微基站(femto)等小站，或者网络设备可以是接入点(Access Point，AP)；基站也可以是中央单元(Central Unit，CU)与其管理和控制的多个传输接收点(Transmission Reception Point，TRP)共同组成的网络节点，网络设备与直接通信的终端侧设备之间的蜂窝通信链路称之为设备到网络(Device to Network，D2N)链路，或称Uu接口。需要说明的是，在本公开实施例中并不限定网络设备的具体类型。
需要说明的是，本公开实施例中可以应用于NR V2X网络，也可以应用于其他采用直通链路进行通信的网络，对此本公开实施例不作限定。
请参见图2，图2是本公开实施例提供的一种直通链路传输方法的流程图，如图2所示，包括以下步骤：
201、第一终端根据配置信息，确定第一信息进行1或者N次传输，其中，N为大于1的正整数。
202、若确定所述第一信息进行N次数传输，则所述第一终端在直通链路上向第二终端传输N次所述第一信息。
203、若确定所述第一信息进行1次数传输，则所述第一终端在所述直通链路上向所述第二终端传输1次所述第一信息。
其中，上述配置信息可以为网络配置信息，或者预配置信息。上述网络配置信息可以为所述网络设备通过广播消息或者RRC信令发送的配置信息；而上述预配置信息可以为网络设备或者所述第一终端预先为所述第一终端配置的信息，或者，所述预配置信息为协议约定信息。
另外，上述第一终端根据配置信息，确定第一信息进行1或者N次传输可以是，根据配置信息确定第一信息是进行1次传输还是进行N次传输。其中，上述配置信息可以包括重复传输次数配置信息，重复传输次数配置信息用于配置是进行1次传输，还是N次传输，例如：该重复传输次数配置信息指示了重复传输次数(1或N)，进一步还可以包括上述N的取值，也就是说，上述N的取值可以是网络设备配置或预配置的。另外，上述配置信息也可以包括用于确定第一信息是进行1次传输还是进行N次传输的门限信息等，或者上述配置信息可以包括第一信息进行N次传输的条件信息等，对此不作限定。
另外，上述第一信息进行1或者N次传输可以是在一次传输过程中第一信息进行1或者N次传输，或者上述第一信息进行1或者N次传输可以是第一信息总共进行传输的次数，例如：当确定进行1次传输时，意味着只传输1次第一信息，即不启动重复传输，当确定进行N次传输时，即除了初始传输1次外，重复传输N-1次。
需要说明的是，上述第二终端可以是一个或者多个终端，也就是说，本公开实施例可以应用于单播、组播和广播场景，对于广播和组播场景，第二终端为多个接收终端，对于单播场景，第二终端为一个接收终端。
本公开实施例中，通过上述步骤可以实现支持第一信息进行N次传输，从而可以提高直通链路的传输可靠性。
作为一种可选的实施方式，上述在所述第一终端确定所述第一信息进行N次传输的情况下，所述第一终端或者网络设备向所述第二终端指示如下至少一项：
所述N的取值；
所述第一信息传输N次所占用的资源位置。
例如：在上述N的取值为协议约定、网络设备配置给所述第二终端或者 所述第二终端预配置，则第一终端或者网络设备可以只将上述资源位置指示给所述第二终端。
其中，第一终端可以通过直通链路信令进行指示，例如：通过SCI或者直通链路RRC信令进行指示，以指示第一信息的传输次数N和/或所述第一信息的N次传输所占用的资源位置，以便于第二终端接收第一信息。
而网络设备可以通过广播消息(System Information Block，SIB)或者RRC信令进行指示，例如：通过终端专属RRC信令向所述第二终端指示第一信息的传输次数N和/或所述第一信息的N次传输所占用的资源位置，以便于第二终端接收第一信息。
其中，配置给第一终端的第一信息重复传输次数和指示给第二终端的第一信息重复传输次数可以是在一个信息中一起配置给第一终端和第二终端，例如SIB广播消息，也可以是在不同的信息中分别配置给第一终端和第二终端，例如RRC消息。
进一步的，上述广播消息还可以用于所述第一终端确定所述第一信息进行1或者N次数传输。也就是说，上述步骤201中的配置信息为网络配置信息的情况下，该网络配置信息即可以用于第一终端确定所述第一信息进行1或者N次数传输，还可以向第二终端指示上述N的取值和上述资源位置中的至少一项，以节约传输开销。
该实施方式中，所述第一终端或网络设备可以指示所述第二终端第一信息的传输次数N或所述第一信息的N次传输所占用的资源位置，以方便第二终端接收第一信息，提高第一信息接收成功的概率。
需要说明的是，当确定第一信息传输1次的情况下，也可以通过上述指示方式，指示第一信息传输1次和所占用的资源位置中的至少一项。
作为一种可选的实施方式，在所述第一终端启用HARQ反馈的情况下，在一次传输过程中，所述第一信息只传输1次；和/或
在所述第一终端停止HARQ反馈的情况下，所述第一终端根据配置信息，确定第一信息进行1或者N次传输。
其中，上述第一终端可以根据如下至少一项确定启用或者停止HARQ反馈：
网络配置信息、预配置信息、信道状态、业务特征和业务QoS。
其中，这里的网络配置信息和预配置信息可以是步骤201中的配置信息，例如：上述网络配置信息还可以用于所述第一终端确定第一信息进行1或者N次数传输；或者，上述预配置信息还可以用于所述第一终端确定第一信息进行1或者N次数传输。当然，这里的网络配置信息也可以与步骤201中的配置信息为不同的配置信息。例如：上述预配置信息不用于所述第一终端确定第一信息进行1或者N次数传输，这样第一终端可以根据其他预配置信息，或者协议约定的重复传输次数，确定第一信息传输1次或者N次。
上述根据信道状态启用或者停止HARQ反馈可以是，不同的信道状态对应启用或者停止HARQ反馈，例如：信道状态较好的情况下，可以停止HARQ反馈，在信道状态较差的情况下，可以启用HARQ反馈等，对此不作限定。
而上述根据业务特征启用或者停止HARQ反馈可以是，根据业务特征与HARQ反馈的关系确定启用或者停止HARQ反馈等，对此不作限定。
而上述根据业务QoS启用或者停止HARQ反馈可以是，例如，根据业务QoS，该直通链路业务的可靠性需求高于业务可靠性门限则启用HARQ反馈，反之，则停用HARQ反馈，又例如，根据业务QoS，该直通链路业务的时延需求低于业务时延门限则启用HARQ反馈，反之，则停用HARQ反馈等，对此不作限定。
该实施方式中，可以实现当第一终端在直通链路传输中启用HARQ反馈时，停止重复传输第一信息，即只传输1次第一信息；当第一终端在直通链路传输中停止HARQ反馈时，启用重复传输第一信息，并根据配置信息确定第一信息进行1或者N次传输，从而可以提高接收成功率。
本公开实施例中，第一终端还可以根据直通链路信道状态、直通链路信道拥塞程度和直通链路业务信息中的至少一项，以及上述配置信息，确定第一信息进行1或者N次传输。
作为一种可选的实施方式，在所述直通链路的链路信息满足预设条件的情况下，所述第一终端根据配置信息，确定第一信息传输N次；和/或
在所述直通链路的链路信息不满足预设条件的情况下，在一次传输过程中，所述第一信息只传输1次；
其中，所述链路信息包括链路状态和/或链路业务信息。
其中，上述预设条件可以是与直通链路信道状态、直通链路信道拥塞程度和直通链路业务信息中至少一项对应，当然，上述预设条件也可以是与其他信息对应，对此不作限定。
例如：在所述第二终端为一个终端的情况下，上述直通链路的链路信息满足预设条件可以是指如下至少一项：
直通链路信道状态低于信道状态门限；
直通链路信道拥塞程度低于信道拥塞门限；
直通链路业务服务质量QoS高于业务QoS门限。
需要说明的是，上述满足预设条件是指如上至少一项可以理解为，在一种情况下，若上述三项任意一项满足，则认为满足上述预设条件，在另一种情况下，若上述三项至少两项满足，则才认为满足上述预设条件，或者，当直通链路信道状态等于信道状态门限、直通链路信道拥塞程度等于信道拥塞门限、通链路业务服务质量QoS等于业务QoS门限中的至少一项满足时，也可以认为满足上述预设条件，这里并不做限定。
例如：在所述第二终端为一个终端的情况下，上述直通链路的链路信息满足预设条件可以是指：
直通链路业务QoS高于业务QoS门限；或者
在所述直通链路业务QoS不高于业务QoS门限情况下，直通链路信道拥塞程度低于信道拥塞门限。
即在QoS高于业务QoS门限的情况下，不考虑直通链路信道拥塞程度，但在直通链路业务QoS不高于业务QoS门限情况下，如果直通链路信道拥塞程度低于信道拥塞门限满足上述预设条件，以确定进行N次传输。
另外，在一种情况下，上述不满足上述预设条件可以是，直通链路信道状态不低于信道状态门限，或者，直通链路信道拥塞程度不低于信道拥塞门限，或者，直通链路业务服务质量QoS不高于业务QoS门限。在另一种情况下，上述不满足上述预设条件可以是，直通链路信道状态不低于信道状态门限、或者通链路信道拥塞程度不低于信道拥塞门限且业务QoS不高于业务QoS门限。或者在另一种情况下，不满足预设条件可以是指直通链路信道状 态不低于信道状态门限、直通链路信道拥塞程度不低于信道拥塞门限、业务QoS不高于业务QoS门限中的至少两项成立。
需要说明的是，上述三项并不限定需要同时存在，例如，在一些方案中只考虑直通链路信道状态、直通链路信道拥塞程度或者直通链路业务QoS。
其中，上述直通链路信道状态可以是信道状态信息(Channel State Information，CSI)、秩指示(Rand Indication，RI)、信道质量指示(Channel Quality Indicator，CQI)、信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)或参考信号接收功率(Reference Signal Receiving Power，RSRP)等信道状态。
而上述信道状态门限则可以是CSI门限、RI门限、CQI门限、SINR门限或RSRP门限等信道状态门限。
该实施方式中，可以实现若直通链路信道状态高于相应门限，表明信道状态较好，则停止重复传输第一信息，即只传输1次第一信息；若直通链路信道状态低于对应门限，表明信道状态较差，则启用重复传输第一信息，并根据配置信息，确定第一信息传输N次，从而提高接收成功率。
进一步的，所述信道状态门限可以包括第一信道状态门限和第二信道状态门限，其中，所述第一信道状态门限大于所述第二信道状态门限；在根据所述配置信息，确定所述第一信息进行N次传输的情况下，所述N的取值范围为N1和N2，且N2为大于或者等于N1的正整数，所述N1为大于1的整数，在所述直通链路信道状态低于所述第二信道状态门限的情况下，所述N的取值为N2，在所述直通链路信道状态低于所述第一信道状态门限，且高于所述第二信道状态门限的情况下，所述N的取值为N1。
这样可以在直通链路信道状态越低，第一信息重复传输的次数越高，以进一步提高接收成功率。
上述直通链路信道拥塞程度可以是信道忙碌比率(Channel Busy Ratio，CBR)门限或信道占用率(Channel occupancy ratio，CR)等，那么，上述信道拥塞门限可以是CBR门限或者CR门限。
该实施方式中，可以实现若直通链路信道拥塞程度高于对应门限，表明信道较为拥塞，则停止重复传输第一信息，即只传输1次第一信息；因为信 道已经较为拥塞了，可用的资源不多，避免更多的占用发送资源，从而避免有可能选不到发送资源或者与其他终端发送信息冲突的情况；若直通链路信道拥塞程度低于对应门限，表明信道不拥塞，即信道资源比较充裕，则启用重复传输第一信息，并根据网络设备配置或预配置的重复传输次数，确定第一信息传输N次，从而提高接收成功率。
进一步的，所述信道拥塞门限可以包括第一信道拥塞门限和第二信道拥塞门限，其中，所述第一信道拥塞门限大于所述第二信道拥塞门限；在根据所述配置信息，确定所述第一信息进行N次传输的情况下，所述N的取值范围为N3和N4，且N4为大于或者等于N3的正整数，所述N3为大于1的整数，在所述直通链路信道拥塞程度低于所述第二信道拥塞门限的情况下，所述N的取值为N4，在所述直通链路信道拥塞程度低于所述第一信道拥塞门限，且高于所述第二信道拥塞门限的情况下，所述N的取值为N3。
这样可以在直通链路信道拥塞程度越低，第一信息重复传输的次数越高，以进一步提高接收成功率。
其中，上述QoS可以包括如下至少一项：
可靠性、时延、优先级和通信范围。
而上述业务QoS门限可以是可靠性门限、时延门限、优先级门限和通信范围门限中至少一项。
该实施方式中，可以实现若直通链路业务QoS，例如可靠性高于可靠性门限，表明业务要求的可靠性较高，或时延高于时延门限，表明业务要求时延较高，或优先级高于优先级门限，表明业务要求优先级较高，或通信范围高于通信范围门限，表明需求的通信范围较远，需要传输多次才能达到传输距离，则启用重复传输第一信息，并根据配置信息，确定第一信息传输N次，从而提高接收成功率，避免重传，降低传输时延；又例如：若直通链路业务QoS，例如可靠性低于可靠性门限，表明业务要求的可靠性不高，或时延低于时延门限，表明业务要求时延较低，或通信范围低于通信范围门限，表明需求的通信范围较近，1次传输就能达到传输距离，则停止重复传输第一信息，即只传输1次第一信息，从而降低传输开销。
进一步的，所述业务QoS门限可以包括第一业务QoS门限和第二业务 QoS门限，其中，所述第一业务QoS门限大于所述第二业务QoS门限；在根据所述配置信息，确定所述第一信息进行N次传输的情况下，所述N的取值范围为N5和N6，且N6为大于或者等于N5的正整数，所述N5为大于1的整数，在所述直通链路业务QoS高于所述第一业务QoS门限的情况下，所述N的取值为N6，在所述直通链路业务QoS高于所述第一业务QoS门限，且低于所述第二业务QoS门限的情况下，所述N的取值为N5。
这样可以在直通链路QoS越高，第一信息重复传输的次数越高，以进一步提高接收成功率。
可选的，在所述第二终端为多个终端的情况下，所述直通链路的链路信息满足预设条件是指如下至少一项：
直通链路信道状态低于信道状态门限的比例高于第一比例门限；
直通链路信道拥塞程度低于信道拥塞门限的比例高于第二比例门限；
直通链路业务QoS高于业务QoS门限。
其中，上述直通链路信道状态、直通链路信道拥塞程度、直通链路业务QoS以及相应的门限可以参见上述实施方式的相关描述，此处不作赘述。
上述直通链路信道状态低于信道状态门限的比例高于第一比例门限可以是，上述多个终端中直通链路信道状态低于信道状态门限的终端在这多个终端所占的比例高于第一比例门限，上述直通链路信道拥塞程度低于信道拥塞门限的比例高于第二比例门限可以是，上述多个终端中直通链路信道拥塞程度低于信道拥塞门限的终端在这多个终端所占的比例高于第二比例门限。
另外，在一种情况下，上述不满足上述预设条件可以是，直通链路信道状态低于信道状态门限的比例不高于第一比例门限，或者，直通链路信道拥塞程度低于信道拥塞门限的比例不高于第二比例门限，或者，直通链路业务服务质量QoS不高于业务QoS门限。在另一种情况下，上述不满足上述预设条件可以是，直通链路信道状态低于信道状态门限的比例不高于第一比例门限、或直通链路信道拥塞程度低于信道拥塞门限的比例不高于第二比例门限且业务QoS不高于业务QoS门限。或者在另一种情况下，不满足预设条件可以是直通链路信道状态低于信道状态门限的比例不高于第一比例门限、直通链路信道拥塞程度低于信道拥塞门限的比例不高于第二比例门限且业务QoS 不高于业务QoS门限中的至少两项成立。
需要说明的是，上述三项并不限定需要同时存在，例如，在一些方案中只考虑直通链路信道状态、直通链路信道拥塞程度或者直通链路业务QoS。
该实施方式中，可以实现当直通链路信道状态低于信道状态门限的比例(即，终端之间的直通链路信道状态低于信道状态门限的数目/多个终端的终端数目)高于第一比例门限时，启用重复传输第一信息，并根据配置信息，确定第一信息传输N次；反之，则停止重复传输第一信息，即只传输1次第一信息。
以及还可以实现当直通链路信道拥塞程度低于信道拥塞门限的比例(即，终端之间的直通链路信道拥塞程度低于信道拥塞门限的数目/多个终端的终端数目)高于第二比例门限时，启用重复传输第一信息，并根据配置信息，确定第一信息传输N次；反之，则停止重复传输第一信息，即只传输1次第一信息。
需要说明的是，上述信道状态门限、信道拥塞门限、业务QoS门限、第一比例门限和第二比例门限中的至少一项为网络配置信息或者预配置信息配置的。
同理，上述网络配置信息还用于所述第一终端确定第一信息进行1或者N次数传输；例如：该网络配置信息可以包括直通链路上述门限的配置信息和重复传输次数配置信息，也就是说，该网络配置信息可以是步骤201中的配置信息。其中，上述门限的配置信息和重复传输次数配置信息可以是在一个信息中一起配置给第一终端，也可以是在不同的信息中分别配置给第一终端。
另外，上述预配置信息还用于所述第一终端确定第一信息进行1或者N次数传输。例如：该预配置信息可以包括直通链路上述门限的配置信息和重复传输次数配置信息，也就是说，该预配置信息可以是步骤201中的配置信息。当然，也可以不包括上述重复传输次数配置信息，当网络设备没有配置重复传输次数时，第一终端可以根据预配置信息，或者协议约定的重复传输次数，确定第一信息传输N次。
进一步的，在所述第二终端为多个终端的情况下，上述直通链路的链路 状态满足预设条件可以是指：
直通链路业务QoS高于业务QoS门限；或者
在所述直通链路业务QoS不高于业务QoS门限情况下，直通链路信道拥塞程度低于信道拥塞门限的比例高于第二比例门限。
即在QoS高于业务QoS门限的情况下，不考虑直通链路信道拥塞程度，但在直通链路业务QoS不高于业务QoS门限情况下，如果直通链路信道拥塞程度低于信道拥塞门限的比例满足上述预设条件，以确定进行N次传输。
其中，上述直通链路业务QoS高于业务QoS门限，以及直通链路信道拥塞程度低于信道拥塞门限的比例的相关说明，可以参见上述相关说明，例如：可以配置两个业务QoS门限。
同样的，上述信道拥塞门限、业务QoS门限、第一比例门限和第二比例门限中的至少一项为网络配置信息或者预配置信息配置的。
例如：该网络配置信息可以包括信道拥塞门限、业务QoS门限、第一比例门限、第二比例门限和重复传输次数配置信息，也就是说，该网络配置信息可以是步骤201中的配置信息。其中，上述信道拥塞门限、业务QoS门限和重复传输次数配置信息可以是在一个信息中一起配置给第一终端，也可以是在不同的信息中分别配置给第一终端。
又例如：该预配置信息可以包括信道拥塞门限、业务QoS门限、第一比例门限、第二比例门限和重复传输次数配置信息，也就是说，该预配置信息可以是步骤201中的配置信息。当然，也可以不包括上述重复传输次数配置信息，当网络设备没有配置重复传输次数时，第一终端可以根据预配置信息，或者协议约定的重复传输次数，确定第一信息传输N次。
进一步的，所述第一比例门限可以包括第一信道状态比例门限和第二信道状态比例门限，其中，所述第一信道状态比例门限大于所述第二信道状态比例门限；在根据所述配置信息，确定所述第一信息进行N次传输的情况下，所述N的取值范围为N6和N7，且N7为大于或者等于N6的正整数，所述N6为大于1的整数，在所述直通链路信道状态低于信道状态门限的比例高于所述第一信道状态比例门限的情况下，所述N的取值为N7，在所述直通链路信道状态低于信道状态门限的比例高于所述第二信道状态比例门限，且低于 所述第一信道状态比例门限的情况下，所述N的取值为N6。
这样可以在直通链路信道状态低于信道状态门限的比例越高，第一信息重复传输的次数越高，以进一步提高接收成功率。
进一步的，所述第二比例门限可以包括第一信道拥塞比例门限和第二信道拥塞比例门限，其中，所述第一信道拥塞比例门限大于所述第二信道拥塞比例门限；在根据所述配置信息，确定所述第一信息进行N次传输的情况下，所述N的取值范围为N8和N9，且N9为大于或者等于N8的正整数，所述N8为大于1的整数，在所述直通链路信道拥塞程度低于信道拥塞门限的比例高于所述第一信道拥塞比例门限的情况下，所述N的取值为N9，在所述直通链路信道拥塞程度低于信道拥塞门限的比例高于所述第二信道拥塞比例门限，且低于所述第一信道拥塞比例门限的情况下，所述N的取值为N8
这样可以在直通链路信道拥塞程度低于信道拥塞门限的比例越高，第一信息重复传输的次数越高，以进一步提高接收成功率。
需要说明的是，在第二终端为多个终端的情况下，业务QoS门限也可以设置两个，具体可以参见上述相关描述，此处不作赘述。
作为一种可选的实施方式，上述传输N次所述第一信息中每次传输第一信息的冗余版本(Redundancy version，RV)号相同或者不同；或者
所述传输N次所述第一信息中每次传输第一信息的RV号为协议约定或者网络设备配置或者预配置。
其中，上述协议约定或者网络设备配置或者预配置可以是指：
每次传输第一信息均使用协议约定的版本号；或者
N次重复传输，按照协议约定的版本号顺序循环使用；或者
N次重复传输都使用该次HARQ重传应该使用的版本号；或者
N次重复传输按照协议约定的顺序，从该次HARQ重传应该使用的版本号开始循环使用版本号。
作为一种可选的实施方式，所述第一终端通过SCI或直通链路RRC信令向所述第二终端指示当前传输的信息的RV版本号，这样可以提高第二终端成功接收到第一信息的概率。
本公开实施例中，第一终端根据配置信息，确定第一信息进行1或者N 次传输，其中，N为大于1的正整数；若确定所述第一信息进行N次数传输，则所述第一终端在直通链路上向第二终端传输N次所述第一信息；若确定所述第一信息进行1次数传输，则所述第一终端在所述直通链路上向所述第二终端传输1次所述第一信息。这样由于可以支持N次传输，从而可以提高直通链路的传输可靠性。

若直通链路信道状态(CSI，CQI或RSRP)高于对应门限，表明信道状态较好，则停止重复传输第一信息，即只传输1次第一信息；
若直通链路信道状态(CSI，CQI或RSRP)，低于该门限，表明信道状 态较差，则启用重复传输第一信息，并根据配置信息，确定第一信息传输N次，从而提高接收成功率；
也可以配置多个信道状态门限，例如门限1和门限2，其中门限1大于门限2，当直通链路信道状态(CSI，CQI或RSRP)，低于门限1且高于门限2，则启用重复传输第一信息，第一信息的传输次数N1；当直通链路信道状态(CSI，CQI或RSRP)，低于门限2，则重复传输第一信息的传输次数N2，其中N2大于等于N1，N1和N2均为网络配置或预配置。

具体流程图如图6所示：
网络设备配置或预配置直通链路信道拥塞门限，例如CBR门限或者CR 门限等。
若直通链路信道拥塞程度高于对应门限，表明信道较为拥塞，则停止重复传输第一信息，即只传输1次第一信息；因为信道已经较为拥塞了，可用的资源不多，避免更多的占用发送资源，从而避免有可能选不到发送资源或者与其他终端发送冲突的情况；
若直通链路信道拥塞程度低于对应门限，表明信道不拥塞，即信道资源比较充裕，则启用重复传输第一信息，并根据网络设备配置或预配置的重复传输次数，确定第一信息传输N次，从而提高接收成功率；
也可以配置多个信道拥塞门限，例如门限1和门限2，其中门限1大于门限2，当直通链路信道拥塞CBR或CR，低于门限1且高于门限2，则启用重复传输第一信息，第一信息的传输次数N3；当直通链路信道拥塞CBR或CR，低于门限2，则重复传输第一信息的传输次数N4，其中N4大于等于N3，N3和N4均为网络配置或预配置。
其中，上述网络配置信息和预配置信息，以及指示N和资源位置可以参见上面实施例的相应描述，此处不作赘述。
实施例5：第一终端在直通链路上的业务QoS
具体流程图如图7所示：
网络设备配置或预配置直通链路业务QoS门限，例如可靠性门限、时延门限、优先级门限和通信范围门限等。
若直通链路业务QoS，例如可靠性高于可靠性门限，表明业务要求的可靠性较高，或时延高于时延门限，表明业务要求时延较高，或优先级高于优先级门限，表明业务要求优先级较高，或通信范围高于通信范围门限，表明需求的通信范围较远，需要传输多次才能达到传输距离，则启用重复传输第一信息，并根据配置信息，确定第一信息传输N次，从而提高接收成功率，避免重传，降低传输时延；
若直通链路业务QoS，例如可靠性低于可靠性门限，表明业务要求的可靠性不高，或时延低于时延门限，表明业务要求时延较低，或通信范围低于通信范围门限，表明需求的通信范围较近，1次传输就能达到传输距离，则停止重复传输第一信息，即只传输1次第一信息，从而降低传输开销；
也可以配置多个QoS门限，例如门限1和门限2，其中门限1大于门限2，当业务QoS，高于门限2且低于门限1，则启用重复传输第一信息，第一信息的传输次数N5；当业务QoS，高于门限2，则重复传输第一信息的传输次数N6，其中N6大于等于N5，N6和N5均为网络配置或预配置。
其中，上述网络配置信息和预配置信息，以及指示N和资源位置可以参见上面实施例的相应描述，此处不作赘述。
实施例6：第一终端在直通链路上的业务QoS和信道拥塞情况

若直通链路业务QoS，例如可靠性高于可靠性门限，表明业务要求的可靠性较高，或时延高于时延门限，表明业务要求时延较高，或优先级高于优先级门限，表明业务要求优先级较高，或通信范围高于通信范围门限，表明需求的通信范围较远，需要传输多次才能达到传输距离，则启用重复传输第一信息，并根据配置信息，确定第一信息传输N次，从而提高接收成功率，避免重传，降低传输时延；
也可以配置多个QoS门限，例如门限1和门限2，其中门限1大于门限2，当业务QoS，高于门限2且低于门限1，则启用重复传输第一信息，第一信息的传输次数N5；当业务QoS，高于门限2，则重复传输第一信息的传输次数N6，其中N6大于等于N5，N6和N5均为网络配置或预配置。
若直通链路业务QoS，例如可靠性低于可靠性门限，表明业务要求的可靠性不高，或时延低于时延门限，表明业务要求时延较低，或通信范围低于通信范围门限，表明需求的通信范围较近，1次传输就能达到传输距离，则根据直通链路信道拥塞情况判断，例如：
若直通链路信道拥塞程度，高于对应门限，表明信道较为拥塞，则停止重复传输第一信息，即只传输1次第一信息；
若直通链路信道拥塞程度，低于对应门限，表明信道不拥塞，即信道资源比较充裕，则启用重复传输第一信息，并根据配置信息，确定第一信息传 输N次。
其中，上述网络配置信息和预配置信息，以及指示N和资源位置可以参见上面实施例的相应描述，此处不作赘述。
