下面结合附图对本公开所提供的反馈信息传输方法、装置及存储介质进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种反馈信息传输方法的流程图。
目前，多种新业务新应用的需求的持续产生，终端直连通信(sidelink)对传输带宽、通信速率、通信时延、可靠性、可扩展性等性能要求会越来越高，如果仅仅依靠运营商有限的授权频谱，将无法满足未来潜在的多样化应用场景和需求，所以需要研究设计能应用在非授权频段上的终端直连通信(sidelink-unlicensed)技术。
针对相关技术中提出的，需要一种解决Sidelink在非授权频段中的PSFCH的LBT失败导致HARQ信息不能被反馈的方法的技术问题，本公开实施例提供一种信息传输方法，以至少解决上述技术问题。
如图2所示，本公开实施例提供的一种反馈信息传输方法，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：
S21：确定物理共享信道PSSCH对应的M个物理反馈信道PSFCH的时频域资源，M为大于1的整数；确定用于发送PSSCH对应的混合自动重传请求HARQ信息的PSFCH；在确定的PSFCH上发送HARQ信息。
目前，根据现有Release 16的PSSCH和PSFCH之间的映射关系，一个时隙slot上传输的PSSCH只有一个反馈资源的位置，第一终端在PSSCH对应的PSFCH上发送混合自动重传请求HARQ信息之前，需要进行对话前监听LBT，只有在LBT成功的情况下，才能够在PSSCH对应的PSFCH上发送混合自动重传请求HARQ信息。
但是，现有的PSSCH和PSFCH之间的映射关系，一个时隙slot上传输的PSSCH仅有一个反馈资源的位置，一旦LBT失败，将会导致第一终端在PSSCH对应的PSFCH上无法发送混合自动重传请求HARQ信息，第二终端无法接收HARQ信息。
基于此，本公开实施例中，确定PSSCH时频域资源对应的M个物理反馈信道PSFCH时频域资源，M为大于1的整数，进一步的，确定用于发送PSSCH对应的混合自动重传请求HARQ信息的PSFCH，进而在确定的PFSCH上发送HARQ信息。
需要说明的是，确定用于发送PSSCH对应的HARQ信息的PSFCH，第一终端在PSFCH上传输PSSCH对应的HARQ信息之前需要进行LBT，本公开实施例中，确定用于发送PSSCH对应的HARQ信息的PSFCH，即该确定的PSFCH已经完成LBT，能够发送PSSCH对应的HARQ信息。
可以理解的是，第一终端本身具有在对话前监听LBT成功的一个PSFCH上发送PSSCH的HARQ信息的能力，或者，在一个PSFCH上LBT失败后，在PSSCH对应的M个PSFCH中该LBT失败的PSFCH之后的PSFCH上发送PSSCH的HARQ信息的能力。
示例性实施例中，M为2，确定PSSCH时频域资源对应的2个PSFCH时频域资源，进一步确定用于发送PSSCH对应的混合自动重传请求HARQ信息的PSFCH为第1个PSFCH，那么，在确定的第1个PSFCH 上发送HARQ信息。
另一示例性实施例中，M为3，确定PSSCH时频域资源对应的3个PSFCH时频域资源，进一步确定用于发送PSSCH对应的混合自动重传请求HARQ信息的PSFCH为第2个PSFCH，那么，在确定的第2个PSFCH上发送HARQ信息。
需要说明的是，上述示例仅作为示意，本公开实施例中M还可以为4或者4以上，上述示例并不作为对本公开实施例的限制，本公开实施例对此不作具体限制。
可以理解的是，PSFCH时频域资源，包括PSFCH时域资源和PSFCH频域资源等。HARQ信息也可以成为HARQ码本等。
基于此，本公开实施例中，确定物理共享信道PSSCH对应的M个物理反馈信道PSFCH的时频域资源，M为大于1的整数；确定用于发送PSSCH对应的混合自动重传请求HARQ信息的PSFCH；在确定的PSFCH上发送HARQ信息。从而，第一终端能够在一个PSFCH的时频域资源上进行LBT失败发送HARQ信息失败后，在M个PSFCH时频域资源中除失败的PSFCH时频域资源外的其他PSFCH时频域资源上进行LBT，并在LBT成功后发送HARQ信息，以提高信息传输的稳定性，提高通信效率。
如图3所示，本公开实施例提供的另一种反馈信息传输方法，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：
S31：根据PSSCH的子信道编号、时间单元编号以及PSSCH与PSFCH之间的映射参数，确定PSSCH对应的M个PSFCH时频域资源，其中，映射参数为M；确定用于发送PSSCH对应的HARQ信息的PSFCH；在确定的PSFCH上发送HARQ信息。
在本公开的实施例中，映射参数为M可以为网络侧设备配置或预配置给第一终端，或者可以通过协议约定，或者从其他设备接收到映射参数为M，本公开实施例对此不作具体限制。
本公开实施例中，根据PSSCH的子信道编号、时隙编号以及与PSFCH的映射参数，能够得到PSSCH与PSFCH具有一对M的映射关系，从而能够确定PSSCH对应的M个PSFCH时频域资源。
示例性的，映射参数为M，M为2，第一个slot的PSSCH根据1对M的映射关系，对应的PSFCH的时频域资源为位于第3个slot的PSFCH资源和第4个slot上的PSFCH资源，在第一个slot的PSSCH对应在第三个slot的PSFCH处LBT失败的情况下，可以使用第四个slot的PSFCH资源，LBT成功后，可以发送HARQ信息，能够提高信息传输的稳定性，提高通信效率。
需要说明的是，上述示例仅作为示意，不作为对本公开实施例的限制，映射参数为M，M还可以为3或者3以上，本公开对此不作具体限制。
在本公开一可选方式中，时间单元可以是帧、或者子帧、或者时隙、迷你时隙、TTI或者符号等。在本公开另一可选方式中，时间单元可以是秒、或者毫秒、或者微秒等。
在一些实施例中，时间单元为时隙slot。
如图4所示，本公开实施例提供的又一种反馈信息传输方法，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：
S41：确定预设时长；确定PSSCH对应的PSFCH时频域资源的数量为M个；确定用于发送PSSCH对应的HARQ信息的PSFCH；在确定的PSFCH上发送HARQ信息。
其中，预设时长的单位可以为时隙slot，确定预设时长可以为网络侧设备配置或预配置给第一终端， 或者可以通过协议约定，或者从其他设备接收到预设时长，本公开实施例对此不作具体限制。
本公开实施例中，确定PSSCH对应的PSFCH时频域资源的数量为M个，可以为网络侧设备配置或预配置给第一终端，或者可以通过协议约定，或者从其他设备接收到相应的配置，本公开实施例对此不作具体限制。
需要说明的是，确定用于发送PSSCH对应的HARQ信息的PSFCH，第一终端在PSFCH上传输PSSCH对应的HARQ信息之前需要进行LBT，本公开实施例中，确定用于发送PSSCH对应的HARQ信息的PSFCH，即该确定的PSFCH已经完成LBT，能够发送PSSCH对应的HARQ信息。
本公开实施例中，在确定预设时长以及PSSCH对应的PFSCH时频域资源的数量为M个，确定用于发送PSSCH对应的HARQ信息的PSFCH，进而在确定的PSFCH上发送HARQ信息。从而，第一终端能够在一个PSFCH的时频域资源上进行LBT失败发送HARQ信息失败后，在M个PSFCH的时频域资源中除失败的PSFCH的时频域资源外的其他PSFCH的时频域资源上进行LBT，并在LBT成功后发送HARQ信息，以提高信息传输的稳定性，提高通信效率。
如图5所示，本公开实施例提供的又一种反馈信息传输方法，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：
S51：确定PSSCH对应的第一个PSFCH时频域资源的位置；根据第一个PSFCH时频域资源的位置、预设时长以及数量为M个，确定PSSCH对应的M个PSFCH时频域资源；其中，预设时长为M个PSFCH时频域资源中相邻两个PSFCH时频域资源之间的时间间隔。
本公开实施例中，确定PSSCH对应的第一个PSFCH时频域资源的位置slotn；确定预设时长sl-PSFCHTimeInterval，确定PSSCH对应的PSFCH时频域资源的数量为M个，确定用于发送PSSCH对应的M个的PSFCH时频域资源；在确定的PSFCH上发送HARQ信息；其中，预设时长为M个PSFCH时频域资源中相邻两个PSFCH时频域资源之间的时间间隔。
其中，预设时长的单位可以为时隙slot，预设时长可以由系统配置与预配置，配置可以基于终端特定ue specific或者小区特定cell specific或者是资源池；或者还可以通过协议约定，或者从其他设备接收到预设时长，本公开实施例对此不作具体限制。
本公开实施例中，确定PSSCH对应的第一个PSFCH时频域资源的位置，可以为根据协议现有的PSSCH与PSFCH之间的映射关系确定的一个PSFCH时频域资源的位置，或者可以通过协议约定，或者从其他设备接收到相应的配置，本公开实施例对此不作具体限制。
示例性的，增加的M个PSFCH资源位置：第一个PSFCH资源时域位置为slot n，第二个增加的PSFCH资源时域位置为slot(n+sl-PSFCH-TimeInterval-r16)，依次计算，直到增加的第M个PSFCH资源时域位置为slot[n+sl-PSFCH-TimeInterval-r16×(M-1)]。
需要说明的是，确定用于发送PSSCH对应的HARQ信息的PSFCH，第一终端在PSFCH上传输PSSCH对应的HARQ信息之前需要进行LBT，本公开实施例中，确定用于发送PSSCH对应的HARQ信息的PSFCH，即该确定的PSFCH已经完成LBT，能够发送PSSCH对应的HARQ信息。
本公开实施例中，在确定PSSCH对应的第一个PSFCH时频域资源的位置，每两个PSFCH时频域资源之间的时间间隔，以及确定PSSCH对应的PSFCH时频域资源的数量为M个，能够确定PSSCH对应的M个PSFCH时频域资源。从而，第一终端能够在一个PSFCH的时频域资源上进行LBT失败发 送HARQ信息失败后，在M个PSFCH的时频域资源中除失败的PSFCH的时频域资源外的其他PSFCH的时频域资源上进行LBT，并在LBT成功后发送HARQ信息，以提高信息传输的稳定性，提高通信效率。
示例性的，根据协议现有的PSSCH和PSFCH之间的映射关系，确定PSSCH对应的一个PSFCH为位于第三个slot的PSFCH资源，进一步的，确定PSSCH对应的PSFCH时频域资源的数量在时域上增加为2个，确定相邻两个PSFCH时域资源之间的时间间隔的预设时长为1个slot，那么，可以确定PSSCH对应的2个PSFCH为位于第3个slot上的PSFCH资源和第4个slot上的PSFCH资源。
在一些实施例中，预设时长为PSFCH的资源周期periodPSFCHresource的整数倍。
如图6所示，本公开实施例提供的又一种反馈信息传输方法，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：
S61：依次在M个PSFCH上进行对话前监听LBT；在第N个PSFCH进行LBT成功的情况下，确定第N个PSFCH为用于发送PSSCH对应的HARQ信息的PSFCH；其中，N为大于1的整数且小于等于M。
本公开实施例中，在确定PSSCH对应的M个PSFCH时频域资源的情况下，确定用于发送PSSCH对应的HARQ信息的PSFCH，第一终端可以通过依次在M个PSFCH上进行对话前监听LBT，在第N个PSFCH进行LBT成功的情况下，确定第N个PSFCH为用于发送PSSCH对应的HARQ信息的PSFCH；其中，N为大于1的整数且小于等于M。
示例性的，N为2，M为3，在确定PSSCH对应的3个PSFCH时频域资源的情况下，确定用于发送PSSCH对应的HARQ信息的PSFCH，第一终端可以通过依次在3个PSFCH上进行对话前监听LBT，在第一个PSFCH上进行LBT失败之后，可以在第2个PSFCH进行LBT，并在第2个PSFCH上进行LBT成功的情况下，确定第2个PSFCH为用于发送PSSCH对应的HARQ信息的PSFCH。
需要说明的是，上述S61可以单独被实施，还可以结合本公开中的任何一个其他步骤一起被实施，例如：本公开实施例中的S21和/或S31和/或S41和/或S51一起被实施，本公开实施例对此不作具体限制。
在一些实施例中，同一个slot的PSFCH，可能存在多个PSSCH的HARQ信息需要传输，从而，需要对不同PSSCH的HARQ信息进行区分。
基于此，如图7所示，本公开实施例提供的又一种反馈信息传输方法，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：
S71：通过频分复用FDM确定在同一时隙上不同的PSSCH对应的不同的PSFCH的频域资源，在频域上采用物理资源块PRB集合的方式指示不同PSSCH对应的不同的PSFCH的频域资源，PRB集合是位图指示的。
本公开实施例中，PSFCH采用频分复用FDM(frequency division multiplexing，频分复用)方式，在频域上采用位图指示的PRB(physical resource block物理资源块)集合的方式区分在相同的slot上不同的PSSCH对应的PSFCH的频域资源，PRB集合1指示第1个PSSCH在相同的slot的PSFCH频域资源的位置，PRB集合M指示第M个PSSCH在同一个的slot的PSFCH频域资源的位置，PRB集合是位图指示的。
示例性的，M为2的情况下，在频域上采用位图指示的两个PRB集合的方式区分在相同的slot上不同的PSSCH对应的PSFCH的频域资源，其中，PRB集合1指示第1个PSSCH在相同的slot的PSFCH频域资源 的位置，PRB集合2指示第2个PSSCH在相同的slot的PSFCH频域资源的位置。

如图8所示，本公开实施例提供的又一种反馈信息传输方法，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：
S81：PSFCH传输的基序列采用循环移位区分相同的PSFCH时频域资源上支持传输的多个PSSCH的HARQ信息，不同的循环移位值对应多个不同PSSCH的HARQ信息。
本公开实施例中，复用PSFCH资源，在相同的时频域PSFCH资源上，同时支持M比特的HARQ反馈,对应M个PSSCH的HARQ反馈结果，但通过循环移位的方法来区分M个PSSCH的反馈，不同的循环移位值表示多个不同的HARQ反馈信息。
示例性的，假设传输是2比特的，即在PSFCH上传输的基序列，基序列经过循环移位携带HARQ信息，循环移位的相位值共有4个值，分别是0，π/2,π，3π/2,表示2比特的HARQ信息所有的可能，即NACK ACK，NACK NACK,ACK NACK,NACK ACK,当相位值为0时，表示是NACK，ACK，即第一个slot的PSSCH的HARQ的结果是NACK，在第二个slot的PSSCH的HARQ的结果是ACK的。

本公开实施例中，设计新的码本，该码本表示多个PSSCH的反馈结果，码本高位到低位分别对应于时隙在从前到后顺序的PSSCH的HARQ信息。
示例性的，第一个slot的PSSCH在第三个slot的PSFCH时，LBT失败，不能使用第三个slot的PSFCH资源来传输HARQ信息，假设在第四个slot上，LBT成功，将对应着第一个slot和第二个slot上的PSSCH的HARQ信息，这时PSFCH可以反馈M比特，如M＝2时，码本设计为10，高位1对应时隙在前的第一个slot的PSSCH的HARQ信息，低位0对应着后面的第二个slot的PSSCH的HARQ信息。
需要说明的是，上述S91可以单独被实施，还可以结合本公开中的任何一个其他步骤一起被实施，例如：本公开实施例中的S21和/或S31和/或S41和/或S51和/或S61一起被实施，本公开实施例对此不作具体限制。

需要说明的是，在PSFCH上传输PSSCH对应的HARQ信息之前需要进行LBT，本公开实施例中，第二终端监听M个PSFCH时频域资源，在LBT成功的PSFCH上接收PSSCH对应的HARQ信息。
可以理解的是，PSFCH时频域资源，包括PSFCH时域资源和PSFCH频域资源等。HARQ信息也可以成为HARQ码本等。

示例性的，在第四个slot的PSFCH的资源上要反馈第一个slot和第二个slot的PSSCH的HARQ信息，配置了PRB集合1为第一个slot的PSSCH在第四个slot的PSFCH的频域资源，PRB集合2为第二个slot的PSSCH在第四个slot的PSFCH的频域资源。
需要说明的是，上述S111可以单独被实施，还可以结合本公开中的任何一个其他步骤一起被实施，例如：本公开实施例中的S101一起被实施，本公开实施例对此不作具体限制。
如图12所示，本公开实施例提供的又一种反馈信息传输方法，该方法由第二终端执行，该方法可以包括但不限于如下步骤：
S121：PSFCH传输的基序列采用循环移位区分相同的PSFCH时频域资源上支持传输的多个PSSCH的HARQ信息，不同的循环移位值对应多个不同PSSCH的HARQ信息。
本公开实施例中，复用PSFCH资源，在相同的时频域PSFCH资源上，同时支持M比特的HARQ反馈,对应M个PSSCH的HARQ反馈结果，但通过循环移位的方法来区分M个PSSCH的反馈，不同的循环移位值表示多个不同的HARQ反馈信息。

示例性的，第一个slot的PSSCH在第三个slot的PSFCH时，LBT失败，不能使用第三个slot的PSFCH资源来传输HARQ信息，假设在第四个slot上，LBT成功，将对应着第一个slot和第二个slot上的PSSCH的HARQ信息，这时PSFCH可以反馈M比特，如M＝2时，码本设计为10，高位1对应时隙在前的第一个slot的PSSCH的HARQ信息，低位0对应着后面的第二个slot的PSSCH的HARQ信息。
需要说明的是，上述S131可以单独被实施，还可以结合本公开中的任何一个其他步骤一起被实施，例如：本公开实施例中的S101一起被实施，本公开实施例对此不作具体限制。
