所述PDSCH传输为使用PDSCH资源传输的下行数据。
DCI中包含有K1信息域，该K1信息域内携带的取值可分为两种，一种是所述第一取值，另一种是所述第二取值。此处的第一取值和所述第二取值的个数都可以一个或多个。例如，所述第一取值可为K1信息域可携带取值中的一个。例如，所述K1信息域包括：3个二进制比特，则K1信息域携带的取值为从0到7。此时，所述第一取值可为0到7中的任意一个。例如，所述第一取值可为0，而第二取值可为1到7中的任意一个。
若第一取值为1个，KI信息域的其他取值均为第二取值，可以使得第二取值具有更大的取值范围，如此使得基站基于K1信息域调度PUCCH资源上传HARQ-ACK信息时的调度灵活性维持最大化。
若K1信息域携带的是第一取值，所述第一取值表示不触发 HARQ-ACK信息的发送。该HARQ-ACK信息可以为基于一次性(one shot)HARQ-ACK反馈机制发送的HARQ-ACK信息。此处的一次性HARQ-ACK反馈机制为：一次性将所有HARQ进程的HARQ-ACK全部发送的一种HARQ-ACK发送机制。当然在本申请实施例中，UE上报的HARQ-ACK信息也可以非一次性HARQ-ACK反馈机制的反馈方式，例如，仅上报当前已经传输的下行数据对应的HARQ进程的HARQ-ACK信息。
若K1信息域携带的是第二取值，则表示触发HARQ-ACK的发送。
在一些实施例中，所述第二取值为所述第一取值不同。
在本申请实施例中，UE接收的第一DCI为K1信息域具有第一取值的DCI，而在第一DCI之后接收的第二DCI为K1信息域具有第二取值的DCI。
由于第二DCI的K1信息域携带有第二取值，会出发UE上报第一DCI所调度PDSCH传输的HARQ-ACK信息。基站可能会下发多个第二DCI。由于基站给一个UE在时间顺序上先后发了多个携带第二取值K1的第二DCI，UE漏检基站发的第一个第二DCI或者漏检了包括第一个第二DCI在内的多个第二DCI,导致UE将自己接收到的第一个DCI误以为是基站发的第一个的第二DCI。在相关技术中，UE将会按照自己收到的第一个DCI的指示的HARQ-ACK资源位置来发送HARQ-ACK信息，基站将接收不到这个HARQ-ACK信息。因为基站用于指示HARQ-ACK传输资源的是其发送的第一个DCI(已经被UE漏检了)。另外，UE实际发送HARQ-ACK的PUCCH资源可能实际上是基站准备用于给别的UE发送上行信息(包括控制信息和数据信息)的。那么这个UE错误的占用了资源将会影响别的UE的上行发送。而使用本申请实施例提供的方法，至少可以减少上述问题的发生，进而减少一个UE占用其他UE传输 HARQ-ACK信息的PUCCH资源的现象，及这种现象导致的基站对其他UE的HARQ-ACK信息的干扰大的现象。
在本申请实施例中，为了确保UE被基站下发给自己的第二DCI触发上报HARQ-ACK信息，减少由于遗漏基站下发给自己的第二DCI导致的占用其他UE上报HARQ-ACK信息的PUCCH资源的情况。在本申请实施例的S130中会根据第一DCI和第二DCI的DAI域携带的取值是否满足预设条件来确定。
例如，第一DCI的DAI携带的取值和第二DCI的DAI携带的取值的差值为预设值，例如，该预设值为1或者DAI可携带最大值减去1等。
当然此处仅是第一DCI的DAI的取值与第二DCI的DAI的取值满足预设条件的一种举例，具体还可以是其他实现方式，在此就不做进一步限定了。
在本申请实施例中，所述DAI可用于对在同一个HARQ-ACK码本中反馈HARQ-ACK信息的PDSCH传输的计数值。
例如，在一些实施例中，所述DAI可包含S个比特；这S个比特共有2 S次方个取值。例如，当所述S等于2时，所述DAI可携带4个取值，且分别是0、1、2及3。
若UE当前接收到的第一DCI的DAI域携带的“0”，若UE当前接收到的第二DCI的DAI域携带的是“2”，若采用第一DCI和第二DCI的DAI域的取值只差为1或3是满足所述预设条件时，则UE可知道当前接收到的第二DCI并非是为自身调度第一DCI所指示PDSCH传输的PUCCH资源的DCI，自己可能漏检了某一个第二DCI。如此，UE并不采用当前DAI域为“2”的第二DCI所调度的PUCCH资源传输第一DCI所调度PDSCH传输的HARQ-ACK信息；从而减少对其他UE的HARQ-ACK信息上报的干扰，提升其他UE上报HARQ-ACK信息的上 报成功率。
所述S130可包括：
根据第二DCI的K1信息域携带的第二取值，确定PDSCH传输所在时隙与PDSCH传输的HARQ-ACK信息传输所在时隙之间的时隙偏移量；
根据第二DCI携带的PUCCH资源指示(PUCCH resource indicator，PRI)信息域的取值确定承载所述HARQ-ACK信息的PUCCH资源。例如，该PRI信息域指示了PUCCH资源的资源索引。
根据需要反馈的HARQ-ACK信息所以占用的比特，确定出包含承载所述HARQ-ACK信息的PUCCH资源集合。
如此，在S130中可以结合第二DCI的K1信息域和PRI信息域及带传输的HARQ-ACK信息所包含的比特数，确定出传输第一DCI所调度PDSCH传输的HARQ-ACK信息的PUCCH资源；并在确定的PUCCH资源上发送所述HARQ-ACK信息。
在一些实施例中，所述第一DCI所包含DAI域的取值为M1；所述第二DCI所包含DAI域的取值为M2，其中，所述M1和所述M2均为自然数。此处的自然数包括：0或正整数。
所述第二DCI所包含下行链路分配索引DAI域的取值与所述第一DCI所包含DAI域的取值满足预设条件，包括：
当M2＝(M1+1)mod N时，确定所述第二DCI所包含DAI域的取值与所述第一DCI所包含DAI域的取值满足预设条件；其中，所述N为所述DAI域能够指示的取值的个数。
此处的mod表示取模。
如此，UE在接收到第二DCI时，可以根据第一DCI和当前接收到的第二DCI中DAI域的取值，确定当前第二DCI是否是调度UE传输第 一DCI所调度的PDSCH的HARQ-ACK信息的DCI，如果是，则根据该第二DCI上报第一DCI所调度PDSCH传输的HARQ-ACK信息。由于基站给一个UE在时间顺序上先后发了多个携带第二取值K1的第二DCI，UE漏检基站发的第一个第二DCI或者漏检了包括第一个第二DCI在内的多个第二DCI,导致UE将自己接收到的第一个DCI误以为是基站发的第一个的第二DCI。在相关技术中，UE将会按照自己收到的第一个DCI的指示的HARQ-ACK资源位置来发送HARQ-ACK信息，基站将接收不到这个HARQ-ACK信息。因为基站用于指示HARQ-ACK传输资源的是其发送的第一个DCI(已经被UE漏检了)。另外，UE实际发送HARQ-ACK的PUCCH资源可能实际上是基站准备用于给别的UE发送上行信息(包括控制信息和数据信息)的。那么这个UE错误的占用了资源将会影响别的UE的上行发送。而使用本申请实施例提供的方法，至少可以减少上述问题的发生，进而减少一个UE占用其他UE传输HARQ-ACK信息的PUCCH资源的现象，及这种现象导致的基站对其他UE的HARQ-ACK信息的干扰大的现象。
在一些实施例中，如图3所示，所述方法还包括：
S140：当所述第二DCI所包含DAI域的取值与所述第一DCI所包含DAI域的取值不满足预设条件时，放弃传输所述第一DCI所调度所述PDSCH传输的HARQ-ACK信息。
此处的，所述放弃传输所述第一DCI所调度所述PDSCH传输的HARQ-ACK信息，包括：
放弃在与所述第一DCI的DAI域的取值不满足预设条件的第二DCI所调度的PUCCH资源上传输所述HARQ-ACK信息。
若本申请实施例提供的方法，应用于在非授权场景下，则在基站占用的一个信道占用时间(Channel Occupied Time，COT)内，下发了一个 或多个K1信息域为第一取值的第一DCI之后，UE会在该COT内继续监听PDCCH信道，UE通常默认为接收到的第一个K1信息域为第一取值的DCI(也即上述第二DCI)为调度自身传输HARQ-ACK信息的DCI，但是在本申请实施例中会进一步核实，即根据两个DCI的DAI域的取值来确定，当前接收的第二DCI是否为调度UE上传第一DCI调度的PDSCH的HARQ-ACK信息的DCI，减少上传HARQ-ACK信息的PUCCH资源的错误占用。故在一些实施例中，若一个UE发现自己接收到的第二DCI的DAI域的取值与第一DCI的DAI域的取值不满足上述预设条件，若想要进一步上传自身的HARQ-ACK信息，则可能会通过非授权频谱信道的占用等告知基站，从而使得基站重新调度传输HARQ-ACK信息的PUCCH资源。或者，UE接收到与第一DCI不满足上述预设条件的第二DCI之后，认为当前还未接收到调度自身传输HARQ-ACK信息的第二DCI，UE会进一步监听非授权频谱信道的PDCCH，直到基站占用非授权频谱信道的COT结束为止。
例如，UE可以根据自身对PDSCH传输的接收情况，例如，发现接收都正确，无需重新接收，则即便错过了调度HARQ-ACK信息反馈的第二DCI，UE认为没有必要再上报了HARQ-ACK信息了，可以不额外请求重传。若UE根据自身对PDSCH传输的接收情况，确认需要重传一个或多个PDSCH传输时，发送额外的触发重传的HARQ-ACK信息。
在本申请实施例中，若UE确定完全放弃第一DCI所调度PDSCH传输的HARQ-ACK信息传输，可以丢弃掉HARQ-ACK信息，例如，释放存储第一DCI所调度PDSCH传输的HARQ-ACK信息的存储空间。
如图4所示，本申请实施例提供一种HARQ-ACK信息传输方法，其中，包括：
S210：下发第一DCI，其中，所述第一DCI所包含时隙偏移量信息 域具有第一取值；
S220：下发第二DCI，其中，所述第二DCI所包含时隙偏移量信息域具有第二取值；若所述第二DCI用于所述第一DCI所调度PDSCH传输的HARQ-ACK信息传输时，所述第二DCI所包含DAI域的取值与所述第一DCI所包含DAI域的取值满足预设条件；
S230：在所述第二DCI所包含DAI域的取值与所述第一DCI所包含DAI域的取值满足预设条件时，根据所述第二DCI，接收所述第一DCI所调度PDSCH传输的HARQ-ACK信息。
该HARQ-ACK信息传输方法可应用于基站中，该基站可为各种类型的基站，例如，eNB或gNB等。
基站会下发第一DCI和第二DCI。一般情况下，第一DCI的下发时间早于第二DCI的下发时间。
若当前下发的第二DCI是调度所述第一DCI所触发PDSCH传输的HARQ-ACK信息传输的DCI，则第二DCI的DAI域的取值会根据第一DCI的DAI域的取值进行确定，以使得第一DCI的DAI域的取值和第二DCI的DAI域的取值满足所述预设条件，以辅助UE确定当前接收的第二DCI是否为自身上传HARQ-ACK信息的PUCCH资源的调度DCI，减少UE错误占用资源的现象，减少错误占用导致的HARQ-ACK信息传输质量差的现象。
在一些实施例中，所述第一DCI所包含DAI域的取值为M1；所述第二DCI所包含DAI域的取值为M2，其中，所述M1和所述M2均为自然数。
所述第二DCI所包含DAI域的取值与所述第一DCI所包含DAI域的取值满足预设条件，包括：
当M2＝(M1+1)mod N时，确定所述第二DCI所包含DAI域的取 值与所述第一DCI所包含DAI域的取值满足预设条件；其中，所述N为所述DAI域能够指示的取值的个数。
例如，若DAI域为2个比特，则DAI能够指示的取值为4个。此时，第一DCI所包含DAI域的取值和第二DCI所包含DAI域的取值需要满足模4加1的上述函数关系式。
在一些实施例中，所述方法还包括：
在所述第二DCI所包含DAI域的取值与所述第一DCI所包含DAI域的取值满足预设条件时，且根据所述第二DCI接收所述第一DCI所调度PDSCH传输的HARQ-ACK信息失败时，确定所述第一DCI所调度PDSCH传输的HARQ-ACK信息传输失败。
例如，确定了HARQ-ACK信息传输失败，基站在间隔配置用于对应HARQ-ACK信息传输的PUCCH资源一段时间后依然没有收到HARQ-ACK信息或者请求调度HARQ-ACK信息传输资源的请求，则基站可以默认UE对第一DCI所调度PDSCH传输接收正确。

在一些实施例中，所述第二取值为所述第一取值不同。
在一些实施例中，所述第二接收模块620和所述第二送模块可均为程序模块；所述程序模块被处理器执行后，能够实现前述第一DCI和第二DCI的下发和HARQ-ACK信息的接收。

以下结合上述任意实施例提供一个个具体示例：
在5G NR中，基站在调度PDSCH传输时，需要为该PDSCH传输指示其对应的HARQ-ACK信息传输的反馈资源。调度该PDSCH传输中的DCI中包含一个K1信息域和PRI信息域，该K1值指示了HARQ-ACK所在的时隙(slot)与PDSCH所在的时隙之间的间隔，该PRI(PUCCH resource indicator)信息域指示了承载该HARQ-ACK信息的PUCCH资源标识(Identification，ID)。根据该DCI中的K1指示可以确定承载HARQ-ACK信息的PUCCH资源所在的时隙。
根据需要反馈HARQ-ACK信息比特数的多少可以确定PUCCH资源集合的索引(即PUCCH资源集合ID)。
由于HARQ-ACK比特数的多少是基站和UE都已经知道的共同信息，因而不需要在DCI中指示。
UE根据DCI中的PRI信息域携带的取值，可以确定在PUCCH资源集合中使用的PUCCH资源的索引(也即PUCCH资源ID)。在一些特定情况下，有时也要联合承载该DCI的控制信道资源来一起判断PUCCH资源ID。
如果使用动态HARQ-ACK码本反馈的方式，则在调度PDSCH的DCI中还包含DAI域。该DAI用于对在同一个HARQ-ACK码本中反馈HARQ-ACK信息的PDSCH进行计数。目前协议中DCI里的DAI域有2bit，以模4计数，如图7所示。
在图1中，DAI域为2个比特，2个比特携带取值有4种，分别是“00”、“01”、“10”及“11”。在图7中的PDSCH1、PDSCH2、PDSCH3、PDSCH4是PDSCH传输的调度编号。
在5G非授权频谱信道(NR-Unlicense，NR-U)中，发送端需要先进行信道监听，监听发现信道中没有干扰时，才能占用信道发送数据，而且 其占用信道的时长不得超过最大占用时长，例如8ms等。对于在信道占用时段(Channel Occupied Time，COT.)的快要结束的位置进行PDSCH传输。由于在COT内，基站已经不能调度UE反馈HARQ-ACK信息。因为PDSCH的解调需要一定的时间，等PDSCH解调完，已经超出信道的最大占用时长了。基站通常会为该PDSCH传输对应的DCI中设置一个非数值(non-numerical value)K1值，以表示在该DCI中没有指示该PDSCH的HARQ-ACK的反馈资源的位置。该非数值即为前述的第一取值。
该PDSCH传输的反馈资源将由基站在下一次进行信道占用时，由第一个指示了正常数值K1的调度DCI来确定。当然，即使在一个COT内，基站也可以在DCI中设置非数值K1，再在本COT内后续的DCI上设置正常数值K1的DCI用来指示HARQ-ACK反馈的资源位置。
上述非数值K1是K1的一个特定的码点(code point)，例如K1总共3比特(bit)，可以表示0-7的数值范围，可以约定K1＝0时，表示non-numerical value，在K1＝1-7时表示正常的K1数值，即PDSCH传输所在时隙与HARQ-ACK信息传输所在之间的间隔时隙的数量，具体可参见如图8所示。
如图9所示，如果UE漏检了上述第一个携带正常数值K1的DCI(也即PDSCH4所对应的DCI，相应的PDSCH4也漏检了)，UE将会以基站发送的第二个携带正常数值K1的DCI(也即PDSCH5所对应的DCI)中指示的HARQ-ACK反馈资源作为发送HARQ-ACK信息的资源。但由于基站并不知道UE发生了漏检，则基站将无法在自己预期的资源位置上接收到HARQ-ACK信息。且，由于UE错误的占用了HARQ-ACK传输资源，可能导致该UE占用了本来是分给其他UE的上行资源，导致其他UE的上行发送出现错误。
当UE接收到了基站使用携带非数值K1的一个或者多个DCI，以及这些DCI调度的一个或者多个PDSCH传输之后，如果UE收到了一个紧邻的 携带正常数值K1的DCI，该DCI调度了发给该UE的PDSCH传输，且该DCI中的DAI域是上一个携带非数值K1的DCI中的DAI域的循环加1，则表明没有发生DCI漏检，该携带正常数值的DCI中指示的HARQ-ACK信息的传输资源就可以用于UE反馈前述多个PDSCH传输的HARQ-ACK信息。如果两个DCI所包含DAI域不满足上述条件，则说明发生了DCI漏检。UE将不反馈前述非数值K1的一个或者多个DCI所调度的一个或者多个PDSCH所对应的HARQ-ACK信息，具体可如图10所示。这样就不会出现UE错误占用上行传输资源的情况。
