本公开实施例涉及通信技术领域，具体涉及一种混合自动重传请求应答(Hybrid automatic repeat request acknowledgement，HARQ-ACK)反馈时序的确定方法及设备。
背景技术
为了增加调度的效率，节省下行控制信息(Downlink Control Information，DCI)开销，新空口(New Radio，NR)版本17(Rel-17)中可能需要考虑采用一个DCI调度多个载波的方式，即一个DCI同时调度在多个载波上进行物理下行共享信道(Physical Downlink Shared Channel，PDSCH)传输。考虑到多个载波可能具有不同的基带参数(numerology，如子载波间隔(Sub-Carrier Spacing，SCS)等)，不同载波上的PDSCH在使用DCI中通知的同一个反馈时序(即K1)值确定传输其HARQ-ACK的时隙或子时隙时，可能无法对应到同一个时隙或子时隙进行HARQ-ACK反馈，但在采用动态(dynamic)HARQ-ACK码本(codebook)时，由于多个载波上的PDSCH是由DCI中的下行分配索引(Downlink Assignment Index，DAI)共同计数的，如果多个载波上的PDSCH在不同的时隙或子时隙进行HARQ-ACK反馈，将导致终端和基站对HARQ-ACK反馈比特数的理解不一致，导致HARQ-ACK传输错误。
当一个DCI可以调度多个载波上的PDSCH进行传输时，如何使用动态HARQ-ACK码本进行多个载波的HARQ-ACK反馈还没有明确的方案。

具体实施方式
新的无线通信系统(5Generation New RAT，5G NR)中支持灵活的定时关系。对于物理下行共享信道(Physical Downlink Shared CHannel，PDSCH)，承载其调度信息的物理下行控制信道(Physical Downlink Control Channel，PDCCH)指示PDSCH与PDCCH之间的调度时序(Scheduling timing)关系(即K0)以及PDSCH到其对应的HARQ-ACK之间的反馈时序(HARQ-ACK timing)关系(即K1)。具体地，PDCCH所使用的DCI格式中的时域资源分配(Time Domain Resource Assignment，TDRA)指示域指示PDSCH所在时隙与PDCCH(也可以说DCI，因为DCI是PDCCH的具体传输格式，两者从描述调度和反馈关系上认为等价)所在时隙的时隙偏移K0。DCI格式中的PDSCH到HARQ-ACK反馈定时(PDSCH-to-HARQ_feedback timing)指示域指示PDSCH结束到HARQ-ACK开始之间的时隙个数K1，即时隙n中传输的PDSCH在时隙n+K1中进行HARQ-ACK传输。
如图1所示，K1的全集为{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}，通常会配置给终端最多8个值。在Rel-15中，K1的值是以时隙(slot)为单位的，即K1＝1表示间隔1个时隙。在Rel-16中，K1的值可以是以时隙或者子时隙(sub-slot)为单位，其中子时隙可以预先配置为2个符号长度(即一个时隙中顺序存在7个子时隙)，或者7个符号长度(即一个时隙中顺序存在2个子时隙)。
具体的，在时隙n中传输的PDSCH或指示半持续调度(Semi-Persistent Scheduling，SPS)资源释放的PDCCH(也成SPS PDSCH release)，先找到与这个PDSCH或SPS PDSCH release的结束位置重叠的最后一个PUCCH时隙(即PUCCH传输所在载波上的SCS确定的时隙)作为参考，以这个参考时隙作为K1＝0时的参考点，进一步根据K1值确定HARQ-ACK传输所在的PUCCH时隙。如图2和图3所示。
5G NR系统中支持半静态(semi-static)和动态(dynamic)两种HARQ-ACK码本(codebook)产生方式。所谓HARQ-ACK codebook即针对在同一个时域位置或上行信道上进行HARQ-ACK反馈的下行传输产生的HARQ-ACK反馈序列。
Dynamic HARQ-ACK codebook是根据下行链路(Down Link，DL)DCI(即调度下行传输的DCI)中的累计下行分配索引(Counter-Downlink Assignment Index，C-DAI)域的指示来进行HARQ-ACK排序、并根据总计DAI(Total-DAI，T-DAI)域来确定HARQ-ACK codebook的总比特数的，因此，可以在不同的反馈时刻根据实际的调度来调整HARQ-ACK codebook的大小，实现动态的改变codebook大小，从而节省HARQ-ACK反馈开销。
具体的，首选需要根据K1、K0以及配置的重复传输次数(如果配置了)，确定一个载波上的激活带宽部分(Band Width Part，BWP)对应的PDCCH检测机会(monitoring occasion)。
如图4所示，假设不进行重复传输，即可以根据n-K1找到一个下行传输机会，进而根据这个下行传输机会的调度关系找到对应的PDCCH monitoring occasion，如果重复次数大于1，则重复传输的PDSCH的K0基于PDSCH重复传输所占用的多个时隙中的第一个时隙确定，重复传输的PDSCH的K1时基于PDSCH重复传输所占用的多个时隙中的最后一个时隙确定的，意味着以下行时隙n-K1到n-K1-N中的N个时隙为PDSCH重复传输的一组时隙，对于该组时隙，其基于K0确定的PDCCH monitoring occasion为时隙n-K1-N对应的PDCCH monitoring occasion，假定K0总是为0，实际K0可以是多个值，如果为多个值，则对应n-K1的一个下行时隙可以确定多个PDCCH monitoring occasion，每个时隙中也可以包含多个PDCCH monitoring occasion。在载波聚合的情况下， 基于每个载波对应的PDCCH monitoring occasion得到所有载波的PDCCH monitoring occasion全集，其中，不同载波上的PDCCH monitoring occasion可能是在时间上不对齐的，则按照先时间(时间前后顺序)后频域(即载波编号从小到大)的方式进行排序。终端在确定的PDCCH monitoring occasion集合中检测使用某种DCI格式(例如格式1-0、格式1-1、格式1-2中的一种或多种)的PDCCH，并根据接收到的PDCCH中的DAI信息(包括C-DAI和T-DAI)产生HARQ-ACK codebook，假设DCI中的C-DAI和T-DAI是基于PDCCH monitoring occasion集合进行设置。C-DAI按照先频域后时域的顺序指示到当前载波上当前PDCCH monitoring occasion已经传输的PDSCH或者指示SPS PDSCH释放的PDCCH的累计个数。T-DAI指示到当前PDCCH monitoring occasion总计在所有载波上传输的PDSCH或者指示SPS PDSCH释放的PDCCH的个数。多个载波上时域对齐的PDCCH monitoring occasion中的DCI中的T-DAI相同，具体如图5所示，其中，C-DAI和T-DAI以各2比特为例，超过4的值用模的方式通过同一个DAI状态来表达，例如2比特DAI“00”状态可以表示1\5\9等数值。
当一个DCI可以调度多个载波上的PDSCH进行传输时，当DCI中的DAI累计了被调度的多个载波上的PDSCH时，需要保证多个载波上的PDSCH在同一个时隙或子时隙进行HARQ-ACK反馈才能保证网络设备和终端根据DCI中的DAI确定的HARQ-ACK序列的大小是理解一致的。而当DCI中对多个被调度的载波上的PDSCH指示同一个K1值时，按照相关技术，如果多个载波的SCS不同，不能保证多个载波上的PDSCH在同一个时隙或子时隙进行HARQ-ACK反馈，此时，如何使用动态HARQ-ACK码本进行多个载波的HARQ-ACK反馈还没有明确的方案。
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。

下面结合实施例1和实施例2介绍本公开的实施方式。
实施例1：如图12和图13所示，根据载波1和载波2上由同一个DCI调度的2个PDSCH中最晚的PDSCH即PDSCH2来确定PDSCH1和PDSCH2共同的HARQ-ACK反馈时隙：
方式1：找到与PDSCH2重叠的最晚一个PUCCH时隙(即载波1上的UL时隙)，即载波1上行时隙2n+2，当DCI中指示的K1＝1时，以2n+2作为参考点(即K0＝0时的时隙是这个时隙)，则K1＝1指示HARQ-ACK的反馈时隙为载波1上的时隙2n+3，即确定在时隙2n+3中传输PDSCH1和PDSCH2的HARQ-ACK；如图12所示；
方式2：找到与PDSCH2所在时隙(即PDSCH2所在载波2上的时隙n+1)重叠的最晚一个PUCCH时隙(即载波1上的UL时隙)，即载波1上行时隙2n+3，当DCI中指示的K1＝1时，以2n+3作为K1的参考时隙，则K1＝1指示HARQ-ACK的反馈时隙为载波1上的时隙2n+4，即确定在时隙2n+4中传输PDSCH1和PDSCH2的HARQ-ACK，如图13所示。
终端在上述确定的反馈时隙中通过PUCCH(当然也可以是通过PUSCH，不影响上述时间(timing)设计)发送包含PDSCH1和PDSCH2的HARQ-ACK的反馈序列，基站在这个时隙中通过PUCCH接收包含PDSCH1和PDSCH2的HARQ-ACK的反馈序列。
本实施例的有益效果：在相关技术中，如果分别对每个PDSCH根据其对应的参考PUCCH时隙以及K1，则会确定与PDSCH1重叠的最晚的一个PUCCH时隙是时隙2n+1，以2n+1为参考，根据K1＝1，则会得到PDSCH1在时隙2n+2反馈HARQ-ACK，从而导致与PDSCH2的HARQ-ACK在不同 的时隙反馈。
实施例2：如图14和15所示，根据参考SCS确定载波1和载波2上由同一个DCI调度的2个PDSCH共同的HARQ-ACK反馈时隙：
方式1：以DCI的SCS(即DCI传输所在的载波的下行SCS)作为参考SCS，即载波1的下行SCS即30kHz作为参考SCS，根据参考SCS的时隙划分即载波1上的时隙划分，则基于载波1上的时隙划分，确定PDSCH1的参考时隙即为载波1上的时隙2n，确定PDSCH2的参考时隙为载波1上的时隙2n+1，两个参考时隙中的最晚一个是时隙2n+1，则以时隙2n+1作为第一参考时隙，找到PUCCH载波上与这个第一参考时隙重叠的最后一个PUCCH时隙(即PUCCH载波上的每一个时隙都认为是可以传输PUCCH的时隙)，即载波1上的UL时隙2n+1。
以载波1上的UL时隙2n+1为参考点(即K0＝0时的时隙是这个时隙)，当DCI中指示的K1＝1时，确定HARQ-ACK的反馈时隙为载波1上的时隙2n+2，即确定在时隙2n+2中传输PDSCH1和PDSCH2的HARQ-ACK；如图14所示。
方式2：以DCI所调度的多个载波的SCS(即下行SCS)中的最小的SCS作为参考SCS，即载波2的15kHz作为参考SCS，根据参考SCS的时隙划分即载波2上的时隙划分，则基于载波2上的时隙划分，确定PDSCH1的参考时隙即为载波2上的时隙n，确定PDSCH2的参考时隙为载波2上的时隙n，仅一个参考时隙，则这个参考时隙即为第一参考时隙，找到PUCCH载波上与这个第一参考时隙重叠的最后一个PUCCH时隙(即PUCCH载波上的每一个时隙都认为是可以传输PUCCH的时隙)，即载波1上的UL时隙2n+1，以载波1上的UL时隙2n+1为参考点(即K0＝0时的时隙是这个时隙)，当DCI中指示的K1＝1时，确定HARQ-ACK的反馈时隙为载波1上的时隙2n+2，即确定在时隙2n+2中传输PDSCH1和PDSCH2的HARQ-ACK，如图15所示。
方式3：以PUCCH的SCS(即PUCCH传输所在载波的上行SCS)为参考，则由于PUCCH与DCI在同一个载波，且PUCCH的SCS与DCI的SCS相同。
可以理解的是，方式3中的基于参考SCS进行处理的过程与方式1相同，不再赘述。
方式4：以DCI所调度的多个载波的SCS(即下行SCS)中的最大的SCS作为参考SCS，即载波1的30kHz作为参考SCS，具体执行过程与方式1类似，不再赘述；
上述方式以与PDSCH本身重叠的规则来寻找PDSCH的参考时隙，如果以与PDSCH传输所在的时隙重叠来寻找PDSCH的参考时隙，同样可以沿用上述方式，本实施例中，得到的结果是相同的，则不再赘述。
可以理解的是，终端在上述确定的时隙中通过PUCCH(当然也可以是通过PUSCH，不影响上述timing设计)发送包含PDSCH1和PDSCH2的HARQ-ACK的反馈序列，基站在这个时隙中通过PUCCH接收包含PDSCH1和PDSCH2的HARQ-ACK的反馈序列。
需要说明的，上述实施例中，仅以基于时隙的HARQ-ACK反馈为例(即K1的单位是时隙)，对于基于子时隙的HARQ-ACK反馈(即K1的单位是子时隙)，上述方式同样适用。
上述实施例中，载波1和2的SCS仅为示例，还可以是其他的SCS组合，载波1上的DCI同时调度载波1和载波2上的PDSCH也为示例，还可以是一个载波上的DCI调度更多个载波，被调度的载波可以包含本载波或者不包含本载波(即如果是载波1发送DCI，DCI调度的载波可以包含或者不包含载波1)，这些情况中上述方式同样适用。
上述以频分双工(Frequency Division Duplexing，FDD)为例，如果是TDD在同一个载波上下行和上行时隙TDM交替，上述方式同样适用。
