下面结合附图对本公开所提供的信息传输方法和装置进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种信息传输方法的流程图。
如图2所示，该方法由第一终端执行，该方法可以包括但不限于如下步骤：
S1：在第一终端在非授权频段传输物理直连反馈信道PSFCH的情况下，进行第一类型的信道接入方式接入信道监听信道或第二类型的信道接入方式接入信道监听信道。
车联网(vehicle to everything，V2X)通信***中，终端与终端之间可以通过直连链路(如：直连链路(sidelink，SL))进行直连通信。为了提高直连通信的可靠性，第三代合作伙伴计划(3rd generation partnership project，3GPP)针对直连链路定义了PSFCH，PSFCH可以用于发送直连反馈控制信息(sidelink feedback control information，SFCI)，SFCI至少可以包括接收端向发送端反馈是否成功接收数据的信息。
示例性实施例中，发送端(例如：第一终端外的其他终端)可以将数据包括在物理直连共享信道(physical sidelink shared channel，PSSCH)中发送给接收端(例如：第一终端)，接收端(例如：第一终端)接收到发送端(例如：第一终端外的其他终端)发送的数据后，可以根据数据的接收情况在PSFCH信道上向发送端(例如：第一终端外的其他终端)发送SFCI，接收端(例如：第一终端外的其他终端)接收到SFCI后，可以根据SFCI选择合适的资源重新调度数据，以提高数据发送成功率，进而提高直连通信的可靠性。
其中，在第一终端在非授权频段中传输PSFCH的情况下，需要按照竞争的方式接入信道，即接入信道前需要进行LBT(listen before talk，对话前监听)。只有在信道空闲时，第一终端才可以接入信道传输PSFCH，相比授权频段，在非授权频段中进行通信具有一定的不确定性，其不确定性由信道的空闲状态导致的，通过竞争的方式可以保证使用该频段中的第一终端接入信道的公平性。
在信道接入过程中，第一终端可以感测信道，例如：使用LBT方式，以评估信道用于PSFCH传输的可用性。信道接入方式，例如可以包括：第一类型的信道接入方式和第二类型的信道接入方式。
其中，第一类型的信道接入方式可以为Type1信道接入方式，第二类型的信道接入方式可以为Type2信道接入方式。
通过实时本公开实施例，在第一终端在非授权频段传输物理直连反馈信道PSFCH的情况下，可以进行第一类型的信道接入方式接入信道监听信道或第二类型的信道接入方式接入信道监听信道。通过这种方式，可以实现第一终端在非授权频段传输PSFCH进行第一类型的信道接入方式接入信道监听信道或第二类型的信道接入方式接入信道监听信道，实现传输PSFCH，以提高直连通信的可靠性。
在一些实施例中，第一终端使用第一信道接入优先级进行第一类型的信道接入方式接入信道监听信道，包括：在第一终端仅传输PSFCH的情况下，第一终端使用网络设备配置的第一信道接入优先级进行第一类型的信道接入方式接入信道监听信道，或者第一终端使用与PSFCH对应的物理直连共享信道 PSSCH上承载的数据的信道接入优先级相同的第一信道接入优先级进行第一类型的信道接入方式接入信道监听信道。
可以理解的是，第一终端在接收另一终端的PSSCH之后，会传输PSFCH至另一终端，在第一终端仅传输PSFCH的情况下，第一终端使用网络设备配置的第一信道接入优先级进行第一类型的信道接入方式接入信道监听信道，或者第一终端使用与PSFCH对应的物理直连共享信道PSSCH上承载的数据的信道接入优先级相同的第一信道接入优先级进行第一类型的信道接入方式接入信道监听信道。
在一些实施例中，根据PSSCH上承载的数据的服务质量流标识，确定PSSCH上承载的数据的信道接入优先级。
本公开实施例中，PSFCH对应的PSSCH上承载的数据的信道接入优先级，根据PSSCH上承载的数据的服务质量流标识进行确定。
在一些实施例中，网络设备配置的第一信道接入优先级，包括：网络设备基于小区特定cell-specific或者终端特定UE-specific配置的第一信道接入优先级。
可以理解的是，网络设备基于小区特定cell-specific配置第一信道接入优先级，可以为网络设备为小区内的终端配置相同的第一信道接入优先级，位于同一小区内的不同终端的信道接入优先级相同；网络设备基于终端特定UE-specific配置的第一信道接入优先级，可以为网络设备为小区内的终端分别配置第一信道接入优先级，位于同一小区内的不同终端的信道接入优先级可以不相同。
在一些实施例中，网络设备配置的第一信道接入优先级，包括：网络设备配置的为最高信道接入优先级的第一信道接入优先级，或者网络设备配置的为非最高信道接入优先级的第一信道接入优先级。
本公开实施例中，把PSFCH作为一种控制信息，例如NR-U(new radio in unlicensed spectrum，新空口-非授权频谱)中的控制信息，例如：DCI(downlink control information，下行控制信息)和UCI(uplink control information，上行控制信息)，网络设备配置的DCI和UCI为最高信道接入优先级P＝1，本公开实施例中，第一终端传输PSFCH的信道接入优先级为网络设备配置的为最高信道接入优先级的第一信道接入优先级，也即第一信道接入优先级P＝1。
本公开实施例中，网络设备配置的为非最高信道接入优先级的第一信道接入优先级，可以理解为，第一终端传输PSFCH的信道接入优先级P还可以为不等于1。
在一些实施例中，第一终端使用第一信道接入优先级进行第一类型的信道接入方式监听信道，包括：在第一终端传输PSFCH之后，还传输PSSCH的情况下，在PSFCH之后传输的PSSCH上承载的数据的信道接入优先级为第二信道接入优先级的情况下，第一终端使用与第二信道接入优先级相同的第一信道接入优先级进行第一类型的信道接入方式监听信道。
可以理解的是，其他终端向第一终端发送某一信息之后，第一终端传输PSFCH至其他终端，以告知其他终端该信息是否成功接收，之后，第一终端还会传输PSSCH至其他终端，第一终端还有其他数据需要新发给其他终端。
其中，第一终端传输PSSCH上承载的数据的信道接入优先级为已知的，例如：第二信道接入优先级，在此情况下，第一终端使用与第二信道接入优先级相同的第一信道接入优先级进行第一类型的信道接入方式监听信道。
在一些实施例中，根据PSSCH上承载的数据的服务质量流标识，确定PSSCH上承载的数据的信 道接入优先级。
本公开实施例中，PSSCH上承载的数据的信道接入优先级根据PSSCH上承载的数据的服务质量流标识进行确定。
在一些实施例中，第一终端使用第一信道接入优先级进行第一类型的信道接入方式监听信道，包括：在第一终端传输PSFCH之后，还传输PSSCH的情况下，在预配置第一终端使用第三信道接入优先级进行第一类型的信道接入方式监听信道，以及PSFCH之后传输的PSSCH上承载的数据的信道接入优先级为第二信道接入优先级的情况下，第一信道接入优先级与第三信道接入优先级和第二信道接入优先级中较低者相同，第一终端使用第一信道接入优先级进行第一类型的信道接入方式监听信道。
本公开实施例中，在预配置第一终端使用第三信道接入优先级进行第一类型的信道接入方式监听信道的情况下，且存在PSFCH之后传输的PSSCH上承载的数据的信道接入优先级为第二信道接入优先级的情况下，在第一终端进行传输PSFCH进行信道接入过程时，对第三信道接入优先级和第二信道接入优先级的大小进行比较，第以信道接入优先级为其中的较低者，第一终端使用第一信道接入优先级进行第一类型的信道接入方式监听信道。
在一些实施例中，预配置第一终端使用第三信道接入优先级进行第一类型的信道接入方式监听信道，还包括：预配置第一终端使用网络设备配置的第三信道接入优先级进行第一类型的信道接入方式监听信道，或者预配置第一终端使用与PSFCH对应的PSSCH上承载的数据的信道接入优先级相同的所述第三信道接入优先级进行第一类型的信道接入方式监听信道。
在一些实施例中，根据PSSCH上承载的数据的服务质量流标识，确定PSSCH上承载的数据的信道接入优先级。

可以理解的是，网络设备基于小区特定cell-specific配置第三信道接入优先级，可以为网络设备为小区内的终端配置相同的第三信道接入优先级，位于同一小区内的不同终端的信道接入优先级相同；网络设备基于终端特定UE-specific配置的第三信道接入优先级，可以为网络设备为小区内的终端分别配置第三信道接入优先级，位于同一小区的不同终端的信道接入优先级可以不同。
在一些实施例中，网络设备配置的第三信道接入优先级，包括：网络设备配置的为最高信道接入优先级的第三信道接入优先级，或者网络设备配置的为非最高信道接入优先级的第三信道接入优先级。
本公开实施例中，把PSFCH作为一种控制信息，例如NR-U(new radio in unlicensed spectrum，新空口-非授权频谱)中的控制信息，例如：DCI(downlink control information，下行控制信息)和UCI(uplink control information，上行控制信息)，网络设备配置的DCI和UCI为最高信道接入优先级P＝1，本公开实施例中，第一终端传输PSFCH的信道接入优先级为网络设备配置的为最高信道接入优先级的第三信道接入优先级，也即第三信道接入优先级P＝1。
本公开实施例中，网络设备配置的为非最高信道接入优先级的第三信道接入优先级，可以理解为，第一终端传输PSFCH的信道接入优先级P还可以为不等于1。
在一些实施例中，第二类型的信道接入方式，包括：Type2A信道接入方式、Type2B信道接入方式和Type2C信道接入方式；该方法，还包括：获取网络设备配置的第一指示信息；根据第一指示信息，第一终端进行Type2A信道接入方式监听信道或Type2B信道接入方式监听信道或Type2C信道接入方式监听信道。
本公开实施例中，第二类型的信道接入方式Type2信道接入方式包括具有不同感测间隔的多个子类型，例如：Type2A信道接入方式、Type2B信道接入方式和Type2C信道接入方式。
对于Type 2A信道接入方式(Cat.2LBT)，第一终端可以在至少感测间隔(例如，25us)感测到信道为空闲之后立即传输PSFCH。
对于Type 2B信道接入过程(Cat.2LBT)，第一终端可以在特定的持续时间(例如，16us)内感测到信道为空闲之后立即传输PSFCH。
对于Type2C信道接入过程(Cat.1LBT)，第一终端可以在不感测信道的情况下传输PSFCH。
示例性实施例中，Type2A信道接入方式，可以为25us的信道的单时隙的检测，开始前25us开始信道检测的。1个16us的检测和1个9us的检测，如果都是空闲，则认为是空闲的。
示例性实施例中，Type2B信道接入方式，可以为固定长度为16微秒的单检测时隙的信道检测，检测在最后的9us的，有4us以上就认为信道是空闲的。(short LBT的方式)
示例性实施例中，Type2C信道接入方式，可以为不进行信道检测，直接传输的，因为本次传输距离上一次传输之间时间差小于16us，则认为是同一次的传输的，传输长度不超过584微秒。
