用户设备(user equipment，UE)接收到PDSCH后，根据PDSCH上承载的数据的译码结果，则在物理上行控制信道(physical uplink control channel，PUCCH)上或物理上行共享信道(physical uplink shared channel)上向网络设备反馈肯定应答(acknowledgement，ACK)或否定应答(negative acknowledgement，NACK)。这种数据传输机制也称为混合自动重传请求确认(hybrid automatic repeat request-acknowledgment，HARQ-ACK)机制。为了提高HARQ-ACK反馈的灵活性，5G新空口(new radio，NR)中引入了HARQ-ACK半静态码本反馈机制，即将不同接收时机接收到的PDSCH对应的HARQ-ACK反馈信息映射到同一个HARQ-ACK码本上同时反馈给网络设备。现有的HARQ-ACK半静态码本反馈机制中，一个下行接收时机至少对应HARQ-ACK码本中的一个比特位置，并没有考虑下行采用时隙聚合的传输方式，从而导致HARQ-ACK半静态码本中存在较多的冗余比特。

如背景技术中所述，NR中引入了HARQ-ACK半静态码本(semi-static codebook)反馈机制，在第三代合作伙伴计划(Third Generation Partnership Project，3GPP)协议中HARQ-ACK半静态码本也称为类型1(Type-1)HARQ-ACK码本。下面对当前协议中的HARQ-ACK半静态码本反馈机制的原理做一个简单的介绍。
网络设备通过无线资源控制(radio resource control，RRC)信令给终端设备配置一个时隙定时值(slot timing values)集合，或者协议预定义一个时隙定时值集合，该时隙定时值集合包括至少一个时隙定时值，其中，每个时隙定时值对应至少一个下行接收时机，每一个接收时机对应HARQ-ACK半静态码本中的一个HARQ反馈位置。这里的接收时机可以用于接收PDSCH中的数据，也可以用于接收PDCCH中的控制信令，如半静态调度(semi-persistent scheduling，SPS)的激活或去激活信令。例如，网络设备可以通过RRC信令给终端设备配置时隙定时值集合为{0,1,4,8,2,3}，该时隙定时值集合中的时隙定时值对应的索引号分别为0,1,2,3,4和5。在本申请中，索引号和索引的含义是相同的，可以互换。
当网络设备和终端设备进行下行信息传输时，可以通过PDCCH在下行控制信息(downlink control information，DCI)中携带一个时隙定时值索引，该索引对应上述时隙定时值集合中的某一个时隙定时值，用于指示本次下行信息传输所在的时隙与承载HARQ-ACK半静态码本的上行信道所在时隙之间距离的时隙个数，具体的，这里的下行信息传输所在的时隙可以是下行信息传输的最后一个符号所在的时隙。例如，PDCCH的DCI中携带的时隙定时值索引可以为3，对应指示的时隙定时值为8。时隙定时值为p表示：如果终端设备检测到一个PDCCH，该PDCCH调度或指示一个下行信息传输，该下行信息传输的最后一个符号位于时隙

那么终端设备应该在时隙n上反馈HARQ-ACK信息，其中，n和p为非负整数，mod表示取模操作，
Figure PCTCN2019081237-appb-000002
为μ所指示的子载波间隔对应的一个无线帧中的时隙总数。本申请中的符号也称为时域符号，可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，也可以是单载波频分多址(single carrier frequency division multiple access，SC-FDMA)符号，其中SC-FDMA又称为带有转换预编码的正交频分复用(orthogonal frequency division multiplexing with transform precoding，OFDM with TP)。
如图2所示，当PDCCH指示的时隙5中的下行信息传输的时隙定时值为8的时候，表示该下行信息传输对应的HARQ反馈信息在时隙13上通过PUCCH或PUSCH反馈给网络设备，即HARQ反馈信息所在的时隙与下行信息传输所在的时隙之间的距离等于8个时隙。由于时隙定时值集合被配置为{0,1,4,8,2,3}，因此，终端设备接收到一个时隙定时值为8的下行信息传输之后，可以根据时隙定时值集合中的其它元素{0,1,4,2,3}的取值确定另外的下行接收时机分别对应时隙9、时隙10、时隙11、时隙12和时隙13。终端设备将在这5个下行时隙上接收到的下行信息对应的HARQ反馈信息可以与时隙5中传输的下行信息对应的HARQ反馈信息一起组成一个HARQ-ACK码本、在时隙13上反馈给网络设备。在时隙9、时隙10、时隙11、时隙12和时隙13上是否有下行信息传输，以及这些下行信息传输中网络设备指示的时隙定时值是否与图2中所示的时隙定时值一致，与业务需求以及网络设备的调度算法相关。当在时隙9、时隙10、时隙11、时隙12和时隙13上没有下行信息传输，那么终端设备会在时隙9、时隙10、时隙11、时隙12和时隙13对应的接收时机对应HARQ-ACK码本中的位置上发送NACK。当在时隙9、时隙10、时隙11、时隙12和时隙13上至少一个有下行信息传输，那么终端设备会根据至少一个下行信息的译码结果，在所述至少一个下行信息所在的时隙对应的接收时机对应HARQ-ACK码本中的位置上发送HARQ反馈信息。如果译码正确，则反馈ACK。如果译码错误，则反馈NACK。
对于数据传输，NR系统支持两种HARQ反馈方式，一种是基于传输块(transport block，TB)的HARQ反馈，即一个TB反馈一比特ACK/NACK信息；另一种是基于码块组(code block group，CBG)的HARQ反馈，即一个TB反馈多个比特的ACK/NACK信息，具体需要反馈多少比特，取决于一个TB被分割成了多少个CBG。与长期演进(long term evolution，LTE)系统一样，NR系统也支持单码字(codeword)和双码字传输。单码字传输在一次数据传输过程中只传输一个TB；双码字传输在一次数据传输过程中传输两个TB。为了描述简洁起见，在本申请中，仅以单码字传输且基于TB的HARQ反馈为例进行描述，即一个HARQ反馈位置只反馈一比特ACK/NACK信息。但可以理解的是，本申请的实施例也可以应用于双码字传输场景以及基于CBG的HARQ反馈场景。
根据上面对HARQ-ACK半静态码本的原理介绍可知，HARQ-ACK半静态码本包括的比特数由时隙定时值集合中的时隙定时值的个数决定，也可以理解为是由时隙定时值集合中的时隙定时值对应的下行接收时机的个数决定。根据时隙定时值集合中的时隙定时值确定的下行接收时机所对应的HARQ反馈信息按照一定的顺序组合成的比特流，构成HARQ-ACK半静态码本，该码本承载在PUCCH或PUSCH上由终端设备发送给网络设备。此顺序为时隙定时值集合中的时隙定时值对应的索引从小到大的顺序。图2所示的HARQ-ACK半静态码本的长度为6比特。
NR中为了提高下行信息传输的可靠性，引入了时隙聚合的传输方式，即一个PDCCH调度多个时隙资源用于传输PDSCH。为了支持时隙聚合的传输方式，网络设备通过RRC信令给终端设备配置聚合因子。以聚合因子等于4为例，终端设备会在PDCCH所指示的4个时隙上接收PDSCH，传输块(transport block，TB)在这四个时隙上使用相同的时域资源重复传输四次。
如图3所示，假设在PDSCH4上，传输块TB4采用时隙聚合的传输方式，在时隙6 到时隙9的时频资源上重复传输了四次，调度TB4的PDCCH上指示的时隙定时值为4，那么在网络设备配置给该终端设备的时隙定时值集合{0,1,4,8,2,3}中的时隙定时值3、2和1对应的时隙上，该终端设备将不再会接收其它PDSCH，或不会再在与PDSCH4相同的时域资源上接收PDSCH，这里的PDSCH4对应时隙内的一组时域符号资源。对于基于时隙的调度，也称为类型A(type A)PDSCH，一个终端设备在一个时隙上只会接收一个PDSCH。对于基于非时隙的调度，也称为类型B(type B)PDSCH，调度的时域长度可以为一个或多个符号，一个终端设备在一个时隙内可以接收一个或多个PDSCH，但在一个时隙的一个符号上最多只能接收一个PDSCH。在这种场景下，时隙定时值3、2和1对应的HARQ-ACK码本中的反馈比特是冗余的。由于时隙聚合的传输方式的引入，导致了HARQ-ACK半静态码本存在冗余比特。如果能将这些冗余比特去掉，可以提升上行HARQ-ACK反馈信息的传输可靠性。
对于下行数据传输，包括Type A PDSCH和Type B PDSCH，由于数据传输所使用的时域符号的位置是灵活可变的，为了降低控制信道的开销，可以预先定义一个下行符号配置列表，调度数据传输的控制信道只需要指示下行符号配置索引就可以确定数据传输所使用的时域符号资源。该下行符号配置列表中的每一个下行符号配置包括起始下行符号的索引信息、下行符号的持续符号数信息以及时隙偏移值信息，时隙偏移值信息用于指示控制信道所在的时隙和与控制信道对应的数据信道所在的时隙之间距离的时隙个数。该下行符号配置列表可以是协议预定义的，也可以是网络设备确定后通过RRC信令配置给终端设备。可选的，该下行符号配置列表可以通过RRC信令中的PDSCH配置列表(pdsch-AllocationList)信元配置给终端设备的，该PDSCH配置列表中的一行是通过RRC信令中的PDSCH时域资源配置(PDSCH-TimeDomainResourceAllocation)信元配置的。在具体实现时，起始下行符号的索引信息和下行符号的持续符号数信息可以通过起始和长度指示(start and length indicator value，SLIV)信息确定。
表1和表2为下行符号配置列表的两个例子。本申请并不限定下行符号配置列表的实现方法，也不限定下行符号配置列表中包含的信息数量。在具体实现时，起始下行符号的索引信息和下行符号的持续符号数信息也可以通过SLIV字段指示，如表2所示。在本申请中，一个下行符号配置对应下行符号配置列表中的一行。可选的，SLIV字段的比特长度为7比特,在RRC信令中，SLIV字段也称为startSymbolAndLength字段。
可选的，SLIV与起始下行符号的索引信息S和下行符号的持续符号数信息L的具体对应关系为：
若(L-1)<＝7，那么SLIV＝14*(L-1)+S；否则，SLIV＝14*(14-L+1)+14-1-S。这里0<L<14-S。

如图4所示，本申请提供了一种反馈信息的传输方法,用于提升上行HARQ-ACK半静态码本的传输可靠性。
S410，网络设备向终端设备发送下行信息，对应的，终端设备接收来自网络设备的下行信息。这里的下行信息可以为下行控制信息也可以为下行数据信息。下行控制信息可以承载在下行控制信道上，下行数据信息可以承载在下行数据信道上。在本申请中，下行控制信道以PDCCH为例，下行数据信道以PDSCH为例。
下行信息的传输对应时隙定时值集合中的第一时隙定时值，第一时隙定时值用于指示该下行信息的传输所在的时隙与承载码本的上行信道所在时隙之间距离的时隙个数。这里所说的码本可以为上述HARQ-ACK半静态码本，该码本中包括该下行信息对应的反馈信息。
需要说明的是，在本申请的实施例中的时隙定时值集合，可以是协议预定义的或网络设备确定后通过RRC信令配置的终端设备的时隙定时值集合K1，也可以是K1的子集，还可以是基于时隙定时值集合K1扩展得到的，例如，根据时隙定时值集合K1和聚合因子扩展得到的新的时隙定时值集合。
可选的，该下行信息的传输所在的时隙与承载码本的上行信道所在时隙之间距离的时隙个数可以是以下中的一种：
a、下行信息的传输的最后一个符号所在的时隙与承载码本的上行信道所在时隙之间距离的时隙个数；
b、下行信息的传输的第一个符号所在的时隙与承载码本的上行信道所在时隙之间距离的时隙个数；
c、下行信息的传输对应的PDCCH的最后一个符号所在的时隙与承载码本的上行信道所在时隙之间距离的时隙个数；
b、下行信息的传输对应的PDCCH的第一个符号所在的时隙与承载码本的上行信道所在时隙之间距离的时隙个数。
S420，终端设备生成码本，在该码本中承载上述下行信息对应的反馈信息。该反馈信息可以根据终端设备接收到的下行信息的译码结果决定，如果译码成功则反馈ACK，如果译码失败则反馈NACK。
下行信息对应的反馈信息在码本中的位置与下行信息传输对应的接收时机相关，接收时机与第一时隙定时值和聚合因子相关，聚合因子为下行信息被重复传输的次数。换句话说，下行信息对应的反馈信息在码本中的位置与第一时隙定时值和聚合因子相关。
S430，终端设备向网络设备发送码本，对应的，网络设备接收来自终端设备的码本。网络设备对接收到的码本进行解调译码。进一步的，网络设备可以根据码本的译码结果确定上述下行信息是否被终端设备正确接收。这里的对接收到的码本进行解调译码，也可以理解为是对承载该码本的上行PUCCH或PUSCH进行解调译码。可以理解的是，解调译码在某些场景下可以只包括解调，而不包括译码。例如，某些场景下可以根据解调结果就直接判断出终端设备是否正确接收了上述下行信息。
在本申请中，聚合因子可以由网络设备通过高层信令或动态信令通知给终端设备的。高层信令，可以是指高层协议层发出的信令，高层协议层为物理层以上的至少一个协议层。其中，高层协议层具体可以包括以下协议层中的至少一个：媒体接入控制(medium access control，MAC)层、无线链路控制(radio link control，RLC)层、分组数据会聚协议(packet data convergence protocol，PDCP)层、无线资源控制(radio resource control，RRC)层和非接入层(non access stratum，NAS)。动态信令，可以是指物理层发出的信令，例如通过下行控制信息DCI发送的信令或信息。下行信息被重复传输的次数，可以理解为下行信息对应的下行信道被传输的最大次数，这些下行信道承载该下行信息。可选的，这些下行信道被同一个DCI指示的。例如，聚合因子为4，下行信息对应的下行信道为PDSCH，那么PDSCH信道被传输的最大次数为4次，这几个PDSCH均承载此下行信息，这几个PDSCH是被一个DCI调度的。例如，聚合因子为4，下行信息对应的下行信道为PDCCH，那么PDCCH信道被传输的最大次数为4次，这几个PDCCH均承载此下行信息。聚合因子可以是针对多个时隙间的下行信息被重复传输的次数。下行信息对应的多个下行信道，是分别在不同时隙上的下行信道。
如步骤S420所述，接收时机与时隙定时值和聚合因子相关。具体的，当时隙定时值集合还包括第二时隙定时值时，当第一时隙定时值和第二时隙定时值的差值的绝对值小于第一门限值时，第一时隙定时值和第二时隙定时值对应的接收时机相同。其中，第一门限值与聚合因子F a相关，例如，第一门限值等于聚合因子F a；或者，第一门限值等于F a+Δ，Δ取值可以为整数，例如为1或-1；或者，第一门限值等于μ·F a，μ取值可以为正实数；或者，第一门限值为以F a为变量的函数。上述接收时机与时隙定时值和聚合因子之间的关系还可以描述为：当第一时隙定时值和第二时隙定时值的差值的绝对值大于或等于第一门限值时，第一时隙定时值和第二时隙定时值对应的接收时机不相同。例如第一时隙定时值为0，第二时隙定时值为2，第一门限值为4，第一时隙定时值和第二时隙定时值的差值的绝对值为2,2小于第一门限值4，第一时隙定时值和第二时隙定 时值对应的接收时机相同。例如第一时隙定时值为0，第二时隙定时值为4，第一门限值为4，第一时隙定时值和第二时隙定时值的差值的绝对值为4,4等于第一门限值4，第一时隙定时值和第二时隙定时值对应的接收时机不同。
当第一门限取值不同，上述判断条件也可能不同，例如，当第一门限取值为F a-1时，上述接收时机与时隙定时值和聚合因子之间的关系可以描述为：当第一时隙定时值和第二时隙定时值的差值的绝对值小于或等于第一门限值时，第一时隙定时值和第二时隙定时值对应的接收时机相同。这时，接收时机与时隙定时值和聚合因子之间的关系还可以描述为：当第一时隙定时值和第二时隙定时值的差值的绝对值大于第一门限值时，第一时隙定时值和第二时隙定时值对应的接收时机不相同。
第一时隙定时值和第二时隙定时值的差值的绝对值，等于第一时隙定时值和第二时隙定时值中的较大值减去第一时隙定时值和第二时隙定时值中的较小值的值。可以理解的是，上述判断条件，可以有多种实现方式，第一时隙定时值和第二时隙定时值的差值可以取绝对值也可以不取绝对值。
上述第一时隙定时值和第二时隙定时值对应的接收时机相同，也可以理解为将满足条件的第一时隙定时值和第二时隙定时值划分到同一个时隙定时值子集中。
第一时隙定时值为第一时隙定时值子集中的一个时隙定时值，第一时隙定时值子集中的每一个时隙定时值均为上述时隙定时值集合中的时隙定时值；第一时隙定时值子集包括至少两个不同的时隙定时值，第一时隙定时值子集中的任意两个不同的时隙定时值之间的差值的绝对值小于第一门限值，第一门限值与聚合因子相关，聚合因子大于1。可选的，第一时隙定时值子集中包括的时隙定时值的个数小于等于聚合因子。通过将差值的绝对值小于一个门限的两个时隙定时值的下行接收时机映射到同一个接收时机或多个相同的接收时机，进一步映射到HARQ-ACK码本中的同一个或相同的多个反馈位置，从而可以有效地减少HARQ-ACK码本中的冗余比特，从而提高HARQ-ACK码本的传输可靠性。
下面对网络设备和终端设备的时隙定时值到接收时机的映射方法进行描述。
一种是从时隙定时值集合中取值最小的时隙定时值开始映射，如图5所示。
S510，根据时隙定时值集合中取值最小的时隙定时值和聚合因子确定时隙定时值对应的接收时机。
一种可选的映射方法：第一时隙定时值对应的接收时机为第一接收时机，第一时隙定时值为时隙定时值集合中大于等于第一数值且小于第二数值的时隙定时值。上述映射方法也可以理解为：当第一时隙定时值满足第一条件时，第一时隙定时值对应的接收时机为第一接收时机；和/或，当第一时隙定时值不满足第一条件时，第一时隙定时值对应的接收时机为不同于第一接收时机的其它接收时机。其中，第一条件为大于等于第一数值且小于第二数值，第一数值等于时隙定时值集合中取值最小的时隙定时值，第二数值等于第一数值与聚合因子之和。该映射方法也可以理解为，第一时隙定时值为第一时隙定时值子集中的一个时隙定时值，第一时隙定时值子集由时隙定时值集合中大于等于第一数值且小于第二数值的时隙定时值组成。
另一种可选的映射方法：第一时隙定时值对应的接收时机为第一接收时机，第一时隙定时值为时隙定时值集合中小于第二数值的时隙定时值。上述映射方法也可以理解 为：当第一时隙定时值小于第二数值时，第一时隙定时值对应的接收时机为第一接收时机；和/或，当第一时隙定时值大于或等于第二数值时，第一时隙定时值对应的接收时机为不同于第一接收时机的其它接收时机。该映射方法也可以理解为，第一时隙定时值为第一时隙定时值子集中的一个时隙定时值，第一时隙定时值子集由时隙定时值集合中小于第二数值的时隙定时值组成。
通过上述接收时机的映射方法，可以将时隙定时值集合K 1中大于等于K 1,m且小于K 1,m+F a的时隙定时值对应到同一个接收时机或多个相同的接收时机；或，可以将时隙定时值集合K 1中小于K 1,m+F a的时隙定时值对应到同一个接收时机或多个相同的接收时机，从而减少了HARQ-ACK码本中的比特数，提高了码本的传输可靠性，其中，m为时隙定时值集合K 1中取值最小的时隙定时值在集合K 1中的索引，F a为聚合因子。
第一接收时机可以是一个接收时机，也可以是多个接收时机。例如，如果是基于1个TB的HARQ反馈且在1个时隙中只能接收一个PDSCH时，那么第一接收时机是一个接收时机。如果是基于2个TB的HARQ反馈，或在一个时隙中接收多于一个PDSCH，或基于CBG的HARQ反馈时，那么第一接收时机可以是多于一个接收时机。
S520，更新时隙定时值集合。
具体的，网络设备和终端设备可以对时隙定时值集合K 1进行更新，将时隙定时值集合中大于等于第一数值且小于第二数值的时隙定时值的元素从时隙定时值集合中去掉；或，将时隙定时值集合中小于第二数值的时隙定时值的元素从时隙定时值集合中去掉。通过对时隙定时值集合K 1的更新，将时隙定时值集合K 1中大于等于K 1,m且小于K 1,m+F a的时隙定时值从时隙定时值集合K 1中去掉；或，将时隙定时值集合K 1中小于K 1,m+F a的时隙定时值从时隙定时值集合K 1中去掉。将时隙定时值集合更新后，可以再循环执行上述S510中的映射过程，直到更新后的时隙定时值集合为空集。可以理解的是，这样就将时隙定时值集合中包括的时隙定时值划分为至少一个时隙定时值子集，每个时隙定时值子集中的元素为时隙定时值集合中的时隙定时值，任意两个时隙定时值子集中的元素没有交集。
基于与S510相同的映射思路，可以得到：第一时隙定时值对应的接收时机为第二接收时机，第一时隙定时值为时隙定时值集合中大于等于第三数值且小于第四数值的时隙定时值；或，第一时隙定时值对应的接收时机为第二接收时机，第一时隙定时值为时隙定时值集合中小于第四数值的时隙定时值。上述映射方法等同于：当第一时隙定时值大于等于第三数值且小于第四数值时，第一时隙时值对应的接收时机为第二接收时机；或，第一时隙定时值小于第四数值时，第一时隙时值对应的接收时机为第二接收时机。其中，第三数值等于时隙定时值集合中大于等于第二数值且取值最小的时隙定时值，第四数值等于第三数值与聚合因子之和。该映射方法也可以理解为，第一时隙定时值为第一时隙定时值子集中的一个时隙定时值，第一时隙定时值子集由时隙定时值集合中大于等于第三数值且小于第四数值的时隙定时值组成，或，第一时隙定时值子集由时隙定时值集合中小于第四数值的时隙定时值组成。
对如图3所示的时隙定时值集合，应用如图5所示的映射方法，可以得到如图6所示的结果，即时隙定时值0、1、2和3对应同一个接收时机或多个相同的接收时机，对 应码本中的同一个反馈位置，即在码本的该反馈位置上只能反馈时隙定时值0、1、2和3中的一个对应的反馈信息。反馈信息包含至少一个比特。可以理解的是，当在时隙定时值0、1、2和3对应的时隙上没有下行信息传输，那么终端设备会在该反馈位置发送反馈信息，反馈信息包括至少一个NACK。当在时隙定时值0、1、2或3对应的时隙上有一个下行信息传输，那么终端设备会根据该下行信息的译码结果，在该反馈位置上发送反馈信息。反馈信息包含至少一个比特。如果译码正确，则在该反馈位置反馈ACK。如果译码错误，则在该反馈位置反馈NACK。
另一种是从时隙定时值集合中取值最大的时隙定时值开始映射，如图7所示。
S710，根据时隙定时值集合中取值最大的时隙定时值和聚合因子确定时隙定时值对应的接收时机。
一种可选的映射方法：第一时隙定时值对应的接收时机为第一接收时机，第一时隙定时值为时隙定时值集合中大于第二数值且小于等于第一数值的时隙定时值。上述映射方法也可以理解为：当第一时隙定时值满足第二条件时，第一时隙定时值对应的接收时机为第一接收时机；和/或，当第一时隙定时值不满足第二条件时，第一时隙定时值对应的接收时机为不同于第一接收时机的其它接收时机。其中，第二条件为大于第二数值且小于等于第一数值,第一数值等于时隙定时值集合中取值最大的时隙定时值，第二数值等于第一数值与聚合因子之差。该映射方法也可以理解为，第一时隙定时值为第一时隙定时值子集中的一个时隙定时值，第一时隙定时值子集由时隙定时值集合中大于第二数值且小于等于第一数值的时隙定时值组成。
另一种可选的映射方法：第一时隙定时值对应的接收时机为第一接收时机，第一时隙定时值为时隙定时值集合中大于第二数值的时隙定时值。上述映射方法也可以理解为：当第一时隙定时值大于第二数值时，第一时隙定时值对应的接收时机为第一接收时机；和/或，当第一时隙定时值小于或等于第二数值时，第一时隙定时值对应的接收时机为不同于第一接收时机的其它接收时机。该映射方法也可以理解为，第一时隙定时值为第一时隙定时值子集中的一个时隙定时值，第一时隙定时值子集由时隙定时值集合中大于第二数值的时隙定时值组成。
通过上述接收时机的映射方法，可以将时隙定时值集合K 1中大于K 1,m-F a且小于等于K 1,m的时隙定时值对应到同一个接收时机或多个相同的接收时机；或，可以将时隙定时值集合K 1中大于K 1,m-F a的时隙定时值对应到同一个接收时机或多个相同的接收时机从而减少了HARQ-ACK码本中的比特数，提高了码本的传输可靠性，其中，m为时隙定时值集合K 1中取值最大的时隙定时值在集合K 1中的索引，F a为聚合因子。
S720，更新时隙定时值集合。
具体的，网络设备和终端设备可以对时隙定时值集合K 1进行更新。例如，将时隙定时值集合中大于第二数值且小于等于第一数值的时隙定时值的元素从时隙定时值集合中去掉；或，将时隙定时值集合中大于第二数值的时隙定时值的元素从时隙定时值集合中去掉。通过对时隙定时值集合K 1的更新，将时隙定时值集合K 1中大于K 1,m-F a且小于等于K 1,m的时隙定时值从时隙定时值集合K 1中去掉；或，将时隙定时值集合K 1中大于K 1,m-F a的时隙定时值从时隙定时值集合K 1中去掉。将时隙定时值集合更新后，可 以再循环执行上述S710中的映射过程，直到更新后的时隙定时值集合为空集。可以理解的是，这样就将时隙定时值集合中包括的时隙定时值划分为至少一个时隙定时值子集，每个时隙定时值子集中的元素为时隙定时值集合中的时隙定时值，任意两个时隙定时值子集中的元素没有交集。
基于与S710相同的映射思路，可以得到：第一时隙定时值对应的接收时机为第二接收时机，第一时隙定时值为时隙定时值集合中大于第四数值且小于等于第三数值的时隙定时值；或，第一时隙定时值对应的接收时机为第二接收时机，第一时隙定时值为时隙定时值集合中大于第四数值的时隙定时值。上述映射方法等同于：当第一时隙定时值大于第四数值且小于等于第三数值时，第一时隙时值对应的接收时机为第二接收时机；或，第一时隙定时值大于第四数值时，第一时隙时值对应的接收时机为第二接收时机。其中，第三数值等于时隙定时值集合中小于等于第二数值且取值最大的时隙定时值，第四数值等于第三数值与聚合因子之差。该映射方法也可以理解为，第一时隙定时值为第一时隙定时值子集中的一个时隙定时值，第一时隙定时值子集由时隙定时值集合中大于第四数值且小于等于第三数值的时隙定时值组成，或，第一时隙定时值子集由时隙定时值集合中大于第四数值的时隙定时值组成。
对如图3所示的时隙定时值集合，应用如图7所示的映射方法，可以得到如图8所示的结果，即时隙定时值1、2、3和4对应同一个接收时机或多个相同的接收时机，对应码本中的同一个反馈位置，即在码本的该反馈位置上只能反馈时隙定时值1、2、3和4中的一个对应的反馈信息。反馈信息包含至少一个比特。可以理解的是，当在时隙定时值0、1、2和3对应的时隙上没有下行信息传输，那么终端设备会在该反馈位置发送反馈信息，反馈信息包括至少一个NACK。当在时隙定时值0、1、2或3对应的时隙上有一个下行信息传输，那么终端设备会根据该下行信息的译码结果，在该反馈位置上发送反馈信息。反馈信息包含至少一个比特。如果译码正确，则在该反馈位置反馈ACK。如果译码错误，则在该反馈位置反馈NACK。
下面描述终端设备如何确定下行接收时机，以便终端根据接收时机确定HARQ-ACK码本的长度以及下行信息对应的反馈信息在码本中的位置，从而减少HARQ-ACK码本的比特长度，提高HARQ-ACK码本的传输可靠性。可以理解的是，网络设备也可以采用相同的确定下行接收时机的过程，以便进一步确定下行信息对应的反馈信息在码本中的位置，从而使得网络设备对HARQ-ACK码本的理解与终端设备保持一致。
如果终端设备需要监测DCI格式1_0的PDCCH但不需要监测DCI格式1_1的PDCCH，则该终端设备的时隙定时值集合K 1固定为{1,2,3,4,5,6,7,8}。如果终端设备需要监测DCI格式1_1的PDCCH，则网络设备通过RRC信令将时隙定时值集合K 1配置给终端设备。如果终端设备需要监测DCI格式1_0的PDCCH和监测DCI格式1_1的PDCCH，则终端设备通过RRC信令和时隙定时值集合{1,2,3,4,5,6,7,8}，确定时隙定时值集合K 1。
对于时隙定时值集合K 1，如果网络设备给终端设备配置了大于1的聚合因子F a，终端设备和网络设备均可以按照如下伪代码确定时隙定时值对应的时隙定时值子集的索引的集合K 1,s：
K 1,C为集合K 1的大小，即集合K 1包括的元素的个数；
k为时隙定时值K 1,k在集合K 1中的索引，将k初始为0；
K 1,k为时隙定时值集合K 1中索引号为k的时隙定时值；
b k为时隙定时值K 1,k对应的时隙定时值子集的索引；
j为时隙定时值对应的时隙定时值子集的索引，将j初始为0；
集合B1用于保存时隙定时值集合K 1中的时隙定时值对应的索引，集合B1中的元素b k和集合K 1中的时隙定时值K 1,k一一对应，将集合B1初始化为空集；
将集合K 1,s初始化为空集；
Th1为第一门限值，第一门限值与聚合因子F a相关，有关第一门限值的详细描述可以参见前面实施例中的相关描述；
方法一：从时隙定时值集合中取值最小的时隙定时值开始确定集合K 1,s。
while集合K 1不为空集
设m为时隙定时值集合K 1中取值最小的时隙定时值在集合K 1中的索引；
Figure PCTCN2019081237-appb-000003
可以理解的是，上述判断条件K 1,k-K 1,m＜Th1也可以写成K 1,k＜K 1,m+Th1；或者，也可以写成|K 1,m-K 1,k|＜Th1；或者,也可以写成(K 1,m-K 1,k)mod K 1,M＜Th1，K 1,M为时隙定时值集合中的时隙定时值的最大值，|·|表示取绝对值操作，mod表示取模操作。在本申请中，将j与集合K 1,s取并集可以理解为将只包含元素j的集合与集合K 1,s取并集。
方法二：从时隙定时值集合中取值最大的时隙定时值开始确定集合K 1,s。
while集合K 1不为空集
设m为时隙定时值集合K 1中取值最大的时隙定时值在集合K 1中的索引；
Figure PCTCN2019081237-appb-000004
Figure PCTCN2019081237-appb-000005
可以理解的是，上述判断条件K 1,m-K 1,k＜Th1也可以写成K 1,k＞K 1,m+Th1；或者,也可以写成|K 1,k-K 1,m|＜Th1；或者,也可以写成(K 1,k-K 1,m)mod K 1,M＜Th1，K 1,M为时隙定时值集合中的时隙定时值的最大值。
对于时隙定时值集合K 1中两个不同的时隙定时值K 1,k1和K 1,k2,如果对应的b k1和b k2相等，则说明时隙定时值K 1,k1和K 1,k2属于同一个时隙定时值子集。对于同一个时隙定时值子集中两个不同的时隙定时值K 1,k1和K 1,k2，对应相同的接收时机，如图6中的时隙定时值0、1、2和3属于同一个时隙定时值子集，图8中的时隙定时值1、2、3和4属于同一个时隙定时值子集。这里相同的接收时机，可以对应相同的多个接收时机，例如，对于非时隙调度，在一个时隙内可以有多个接收时机。进一步的，相同的接收时机对应HARQ-ACK码本中的相同的反馈位置，一个反馈位置可以对应至少一个比特。
可选的，下行信息的传输对应的接收时机还与第一时隙定时值子集在时隙定时值集合中的索引相关。例如，下行信息的传输对应的接收时机的索引是根据第一时隙定时值子集在时隙定时值集合中的索引确定。这里的第一时隙定时值子集在时隙定时值集合中的索引是指，该时隙定时值集合包括至少一个时隙定时值子集，时隙定时值集合中的每一个时隙定时值子集在该时隙定时值集合中有一个唯一的索引。进一步，一种实现的可能是，下行信息的传输对应的接收时机的索引为第一时隙定时值子集在时隙定时值集合中的索引。具体的，若终端设备不支持在一个时隙中接收多于一个PDSCH的能力或终端设备被指示在一个时隙中不接收多于一个PDSCH，那么下行信息的传输对应的接收时机的索引为第一时隙定时值子集在时隙定时值集合中的索引。另一种实现的可能是，当以下两个条件中的至少一个满足时，第一时隙定时值子集在时隙定时值集合中的子集索引对应多个接收时机的索引：终端设备支持在一个时隙中接收多于一个PDSCH的能力；终端设备被指示在一个时隙中接收多于一个PDSCH。下行信息的传输对应的接收时机的索引为该多个接收时机的索引中的一个。下行信息的传输对应的接收时机的索引还需要根据下行信息的传输对应的下行符号配置进一步确定。
为了确定时隙定时值子集对应的接收时机的索引，一种可能的实现是：网络设备或终端设备可以根据时隙定时值子集在时隙定时值集合中的索引值从小到大的顺序依次确定时隙定时值子集对应的接收时机的索引。对于如图6所示的时隙定时值子集，可以 依次确定时隙定时值子集{0,1,2,3}、时隙定时值子集{4}和时隙定时值子集{8}对应的接收时机的索引为0、1和2。另一种可能的实现是，对于如图8所示的时隙定时值子集，可以依次确定时隙定时值子集{8}、时隙定时值子集{1,2,3,4}和时隙定时值子集{0}对应的接收时机的索引为0、1和2。可以理解的是，网络设备或终端设备也可以根据时隙定时值子集在时隙定时值集合中的索引值从大到小的顺序依次确定时隙定时值子集对应的接收时机的索引。
对于下行重复传输，聚合因子指示的是在时域上连续重复发送下行信息的次数。如果用于重复传输的时频资源与上行符号冲突了，即在重复传输的时频资源中的某一个时隙上至少包括一个上行符号。第一种处理方式是在该冲突符号所在的时隙上不再发送该下行信息，重复传输次数减少一次；第二种处理方式可以是将重复传输延后一个时隙继续发送。例如，PDCCH调度的下行信息在时隙0,1,2和3上重复传输四次，但时隙2中有一个符号被用于上行传输了，则此时下行信息改为在时隙0,1,3和4上重复传输四次，即在与上行符号冲突的时隙上不传输该下行信息，而延后一个时隙进行重复传输。在这种场景下，也可以理解为，接收时机与第一时隙定时值、聚合因子和上行符号的配置位置相关。网络设备和终端设备可以通过第一时隙定时值、聚合因子和上行符号的配置位置，确定接收时机。
本申请的实施例，在下行信息重复传输的场景下，考虑聚合因子，将差值在一定门限内的多个时隙定时值对应为同一个时隙定时值子集或对应为相同的接收时机，进一步将差值在一定门限内的多个时隙定时值对应到HARQ-ACK码本中相同的反馈位置，从而起到减少冗余比特的目的。
可以理解是，对于时隙定时值集合K 1，如果聚合因子F a等于1或者没有配置聚合因子，网络设备和终端设备也可以不执行以上伪代码的判断，而是直接使用现有技术的半静态码本的定义方式，本申请对此不做限定。
可以理解的是，上述伪代码只是给出了本申请的实施例的可能的实现方式，并不作为对本申请实施例的限定，本申请的实施例还可以有其它的实现方式。
由于采用了时隙聚合的传输方式，根据时隙定时值子集内的各个时隙定时值和聚合因子确定的传输资源在时域上有部分重叠，从而导致终端设备在该时隙定时值子集中的某一个时隙定时值对应的接收时机上接收到了下行数据，就不能在该时隙定时值子集中的另一个时隙定时值对应的相同的时域符号上接收其它下行数据。因此，可以通过时隙定时值子集对应的接收时机的数量确定该时隙定时值子集中的任意一个时隙定时值对应的接收时机的数量。也就是说，第一时隙定时值对应的接收时机的数量等于第一时隙定时值子集对应的接收时机的数量。第一时隙定时值对应的接收时机中包括上述下行信息的传输对应的接收时机，也就是说，第一时隙定时值对应的接收时机包括至少一个接收时机，上述下行信息的传输对应的接收时机为第一时隙定时值对应的接收时机中的一个。
现有技术中,终端设备或网络设备对每个时隙定时值单独确定接收时机，然后对各个时隙定时值对应的接收时机数进行累加，进一步根据累加后的接收时机数确定HARQ-ACK码本中的比特数。与现有技术相比，根据上述方法确定的接收时机的数量大大降低，从而有效减少了HARQ-ACK码本中的比特数。
下面对网络设备和终端设备如何确定第一时隙定时值子集对应的接收时机的数量进行详细描述。
第一时隙定时值子集对应的接收时机的数量等于第一下行符号配置集合G1对应的接收时机的数量，其中，G1是根据第一时隙定时值子集确定的。具体的，G1可以根据第一时隙定时值子集中的所有时隙定时值确定，G1也可以根据第一时隙定时值子集中的某一个时隙定时值确定，或者，G1也可以根据第一时隙定时值子集中的至少两个时隙定时值确定。G1为下行符号配置列表的子集或全集，有关下行符号配置列表更详细的描述可以参见上述表1中的相关描述。
在UE不支持一个时隙内接收多个物理下行数据信道或该UE被指示不在一个时隙内接收多个物理下行数据信道的条件下，G1对应的接收时机的数量等于一。
在UE支持一个时隙内接收多个物理下行数据信道的条件下，G1对应的接收时机的数量为该G1中时域不重叠的下行符号配置的最大个数。可以理解的是，这里的UE支持一个时隙内接收多个物理下行数据信道可以包括两种情况：一种是UE支持一个时隙内接收多个物理下行数据信道；另一种是UE支持一个时隙内接收多个物理下行数据信道且该UE被指示可以在一个时隙内接收多个物理下行数据信道。
网络设备和终端设备可以按照如下方法对第一下行符号配置集合G1中的下行符号配置进行分组得到多个下行符号配置子集SDSA(j)，j为下行符号配置子集SDSA(j)在G1中的索引，j为非负整数。
(1)设j的初始值等于0。
(2)确定G1中的下行符号配置对应的最后一个下行符号的符号索引的最小值为n。可以理解的是，下行符号配置对应的最后一个下行符号的符号索引由所述下行符号配置中的起始下行符号的索引信息以及下行符号的持续符号数信息确定的，即最后一个下行符号的符号索引为起始下行符号的索引与下行符号的持续符号数之和再减一。
(3)将G1中起始下行符号的符号索引小于或等于n的下行符号配置分配到同一个下行符号配置子集SDSA(j)；
更新G1：将SDSA(j)中的下行符号配置从G1中删除；
更新j的取值为j加1。
(4)重复执行步骤(2)和(3)直到G1为空集。
上述对第一下行符号配置集合G1中的下行符号配置进行分组的过程中，可以在分组之前将G1赋值给一个临时变量G1_TEMP，上述过程中对G1的操作替换为对G1_TEMP的操作，从而使得G1在这个分组的过程中保持不变。
以表1所示的索引为1至7的下行符号配置组成的下行符号配置集合G1为例。如图11所示，G1中的下行符号配置#1对应的最后一个下行符号的符号索引为1，是G1中下行符号配置对应的最后一个下行符号的符号索引的最小值。所以，第一次执行步骤(2)可以得到n等于1。在本申请中符号#后面跟的数字可以表示索引的取值。下行符号配置#1、下行符号配置#2和下行符号配置#3的起始下行符号的符号索引均等于0，所以第一次执行步骤(3)，可以将下行符号配置#1、下行符号配置#2和下行符号配置#3分配到同一个下行符号配置子集SDSA(0)。第一次执行完步骤(3)之后，G1中还包括下行符号配置#4、下行符号配置#5、下行符号配置#6和下行符号配置#7。
第二次执行步骤(2)的时候，更新后的G1中的下行符号配置#4对应的最后一个下行符号的符号索引为7，是G1中下行符号配置对应的最后一个下行符号的符号索引的最小值。所以，第二次执行步骤(2)可以得到n等于7。下行符号配置#4的起始下行符号的符号索引为4，下行符号配置#5的起始下行符号的符号索引为7，所以第二次执行步骤(3)，可以将下行符号配置#4和下行符号配置#5分配到同一个下行符号配置子集SDSA(1)。第二次执行完步骤(3)之后，G1中还包括下行符号配置#6和下行符号配置#7。
第三次执行步骤(3)，可以将下行符号配置#6分配到下行符号配置子集SDSA(2)，该下行符号配置子集(subset of downlink symbol allocation，SDSA)中只包括下行符号配置#6。
第四次执行步骤(3)，可以将下行符号配置#7分配到下行符号配置子集SDSA(3)，该下行符号配置子集中只包括下行符号配置#7。
通过采用上述方法，第一下行符号配置集合G1被分成了四个下行符号配置子集SDSA(0)、SDSA(1)、SDSA(2)和SDSA(3)，对应的这四个子集在G1中的索引分别为0、1、2和3。
按照上述方法，可以对第一下行符号配置集合G1中的下行符号配置进行分组得到至少一个下行符号配置子集。下行符号配置子集的总个数即为G1中时域不重叠的下行符号配置的最大个数。当G1包括至少两个不同的下行符号配置子集时，对于G1中任意两个不同的下行符号配置子集第二SDSA和第三SDSA，总是可以在第二SDSA中找到下行符号配置C1，在第三SDSA中找到下行符号配置C2，使得下行符号配置C1和下行符号配置C2对应的下行符号在时域上不重叠。两个下行符号在时域上不重叠，可以理解为这两个下行符号的符号索引不同。
根据上述方法确定的第一SDSA中的所有下行符号配置对应的下行符号在时域上部分或全部重叠。网络设备不会一个时隙内，使用同一个下行符号配置子集中的多于一个下行符号配置调度多于一个PDSCH数据。所以对于同一个下行符号配置子集中的所有下行符号配置可以对应同一个接收时机，从而可以有效减少接收时机数，对应的也就减少了HARQ-ACK码本中的反馈比特数。
假设上述下行信息的传输所对应的下行符号配置为第一下行符号配置，第一下行符号配置为第一SDSA中的一个下行符号配置。则，上述下行信息的传输对应的接收时机还与第一SDSA在G1中的子集索引相关。可以理解的是，在本申请中，因素A与因素B相关，可以理解为信息A可以根据因素B确定，进一步的，信息A为接收时机，也可以理解为接收时机的索引可以根据因素B确定。例如，上述下行信息的传输对应的接收时机的索引可以根据第一SDSA在G1中的子集索引确定。网络设备和终端设备可以根据G1中的下行符号配置子集的索引，依次确定G1中的下行符号配置子集对应的接收时机的索引。
根据第一时隙定时值子集，有两类方法可以确定第一时隙定时值子集对应的第一下行符号配置集合G1。
第一类：对第一时隙定时值子集中的每一个时隙定时值对应的下行符号配置集合取并集，得到第一时隙定时值子集对应的下行符号配置集合。
G1为第一时隙定时值子集中的每一个时隙定时值对应的下行符号配置集合的并集，其中，每一个时隙定时值对应的下行符号配置集合为上述下行符号配置列表的子集或全集。
以时隙定时值0,1,2和3组成第一时隙定时值子集为例，第一时隙定时值子集对应的第一下行符号配置集合G1为时隙定时值0对应的下行符号配置集合、时隙定时值1对应的下行符号配置集合、时隙定时值2对应的下行符号配置集合和时隙定时值3对应的下行符号配置集合的并集。
有两种方法可以进一步确定第一时隙定时值子集中的每一个时隙定时值对应的下行符号配置集合。
方法1A:根据时隙定时值对应的单个下行时隙，确定下行符号配置列表中的下行符号配置的有效性，从而进一步确定由有效的下行符号配置组成的该时隙定时值对应的下行符号配置集合。
对于第一时隙定时值子集中的任意一个时隙定时值ST1对应的第二下行符号配置集合G2，该G2不包括上述下行符号配置列表中满足以下条件的第二下行符号配置：
第二下行符号配置对应的下行符号与第一时隙T1中的上行符号部分或全部重叠，或第二时隙T2中不包括控制信道监听时机。其中，所述第二下行符号配置对应的下行符号是由所述第二下行符号配置中的起始下行符号的索引信息以及下行符号的持续符号数信息确定的。
在本申请的实施例中，控制信道监听时机可以是物理下行控制信道监听时机(PDCCH monitoring occasion)。PDCCH monitoring occasion可以是针对某一类型的PDCCH配置的，例如，可以分别针对UE特定的PDCCH和公共PDCCH分别配置PDCCH monitoring occasion。这里的不包括控制信道监听时机可以是不包括某一特定类型的PDCCH的PDCCH monitoring occasion。另外，在某些场景下，配置的PDCCH monitoring occasion可能会不可用，例如，当发生带宽部分(bandwidth part，BWP)切换后，BWP切换之前配置的PDCCH monitoring occasion则不可用。又例如，公共配置的PDCCH monitoring occasion对于要接收UE特定的PDCCH来说也是不可用的。又例如，配置的PDCCH monitoring occasion与配置的上行符号时域上重叠了则认为该PDCCH monitoring occasion不可用。对于这些不可用的PDCCH monitoring occasion，也可以理解为不包括PDCCH monitoring occasion。
第二下行符号配置对应的下行符号与第一时隙T1中的上行符号部分或全部重叠，是指第二下行符号配置对应的下行符号中至少有一个下行符号与第一时隙T1中的上行符号在时域上重叠，即包括了相同的符号索引。以第二下行符号配置为图11中的下行符号配置#1、时隙定时值为图6所示的时隙定时值0为例，则T1的时隙索引为13，T1也可以称为时隙13，第二下行符号配置对应的下行符号与第一时隙T1中的上行符号部分或全部重叠是指在时隙13中的符号索引0和符号索引1对应的符号中至少有一个是上行符号。
如果第二下行符号配置对应的下行符号与第一时隙T1中的上行符号部分或全部重叠，则说明网络设备在第一时隙T1上不会使用该第二下行符号配置进行下行数据调度，或即使网络设备在第一时隙T1上使用该第二下行符号配置进行下行数据调度时终端设 备也不会进行数据接收和处理，因此该第二下行符号配置被认为是一个无效的下行符号配置，在计算下行接收时机的个数时候可以不考虑该第二下行符号配置。同样的，如果第二时隙T2中不包括控制信道监听时机，则说明该第二下行符号配置也是一个无效的下行符号配置，网络设备不会使用该第二下行符号配置进行下行数据调度。
T1为根据时隙定时值ST1和承载码本的上行信道所在时隙确定的时隙。具体的，T1的时隙索引可以等于承载码本的上行信道所在时隙的索引减去时隙定时值ST1。例如，承载码本的上行信道所在时隙的索引为n，时隙定时值ST1的取值即为ST1，T1的时隙索引＝(n-ST1)。可选的，将上述差值对一个无线帧内包括的时隙个数取模作为T1的时隙索引。例如，T1的时隙索引＝(n-ST1)mod M，M为一个无线帧内包括的时隙个数，mod表示取模操作。例如，对于15千赫兹(kilohertz，kHz)的子载波间隔，M为10；对于30kHz的子载波间隔，M为20；对于60kHz的子载波间隔，M为40；对于120kHz的子载波间隔，M为80；对于240kHz的子载波间隔，M为160。
T2为根据时隙定时值ST1、第二下行符号配置中的时隙偏移值信息、聚合因子和承载码本的上行信道所在时隙确定的时隙。具体的，T2的时隙索引可以等于承载码本的上行信道所在时隙的索引减去时隙定时值ST1、第二下行符号配置中的时隙偏移值信息K0和聚合因子F a三者之和再加1。例如，T2的时隙索引＝(n–ST1-K0-F a+1)。可选的，可以进一步将上述计算结果对一个无线帧内包括的时隙个数取模作为T2的时隙索引。例如，T2的时隙索引＝(n–ST1-K0-F a+1)mod M。
可选的，方法1A还有另一种可能的实现方式。对于第一时隙定时值子集中的任意一个时隙定时值ST1对应的第二下行符号配置集合G2，该G2由上述下行符号配置列表中满足以下条件的第七下行符号配置组成：
第七下行符号配置对应的下行符号与第五时隙T5中的上行符号在时域上不重叠，且第六时隙T6中包括至少一个控制信道监听时机。其中，第七下行符号配置对应的下行符号是由第七下行符号配置中的起始下行符号的索引信息以及下行符号的持续符号数信息确定的。T5为根据ST1和承载码本的上行信道所在时隙确定的时隙。T6为根据ST1、第七下行符号配置中的时隙偏移值信息、聚合因子和承载码本的上行信道所在时隙确定的时隙。
第七下行符号配置与第二下行符号配置不同。可选的，由第七下行符号配置与第二下行符号配置组成下行符号配置列表。
有关T5的确定过程可以参考上述T1的确定过程直接得到，T6的确定方法可以参考上述T2的确定方法直接得到，在此不加赘述。
方法1B:考虑聚合因子，根据时隙定时值对应的连续的多个下行时隙，确定下行符号配置列表中下行符号配置的有效性，从而进一步确定由有效的下行符号配置组成的该时隙定时值对应的下行符号配置集合。
对于第一时隙定时值子集中的任意一个时隙定时值ST2对应的第三下行符号配置集合G3，该G3不包括所述下行符号配置列表中满足以下条件的第三下行符号配置：
第三下行符号配置对应的下行符号与第一时隙集合TG1中的每个时隙的上行符号均部分或全部重叠，或，第三时隙T3中不包括控制信道监听时机。其中，第三下行符号配置对应的下行符号是由第三下行符号配置中的起始下行符号的索引信息以及下行符 号的持续符号数信息确定的。
以第三下行符号配置为图11中的下行符号配置#1、时隙定时值为图6所示的时隙定时值0为例，则第一时隙集合TG1中的时隙对应的时隙索引的集合为{10，11，12，13}，第三下行符号配置对应的下行符号与第一时隙集合TG1中的每一个时隙的上行符号均部分重叠或全部重叠，是指在第一时隙集合TG1的每一个时隙的符号0和符号1中都至少有一个是上行符号。
TG1是由根据ST2、聚合因子和承载码本的上行信道所在时隙确定的时隙组成的集合。具体的，可以首先根据时隙定时值ST2和所述承载码本的上行信道所在时隙确定出一个参考时隙，则TG1为以该参考时隙为基准向前的连续多个时隙，包括该参考时隙自身。TG1包括的时隙的个数等于聚合因子F a。例如，承载码本的上行信道所在时隙的时隙索引为n，时隙定时值ST1的取值即为ST1，具体的，TG1中的时隙对应的时隙索引的集合为：{n-ST1,n–ST1–1,…,n-ST1-F a+1}。可选的，将上述差值对一个无线帧内包括的时隙个数取模作为TG1中的时隙对应的时隙索引。即TG1中的时隙对应的时隙索引的集合为{(n-ST1)mod M,(n–ST1–1)mod M,…,(n-ST1-F a+1)mod M}。
T3为根据ST2、第三下行符号配置中的时隙偏移值信息、聚合因子和承载码本的上行信道所在时隙确定的时隙。T3的确定方法可以参考方法1A中T2的确定方法直接得到，这里不加赘述。
可选的，方法1B还有另一种可能的实现方式。对于第一时隙定时值子集中的任意一个时隙定时值ST2对应的第三下行符号配置集合G3，该G3由上述下行符号配置列表中满足以下条件的第八下行符号配置组成：
第八下行符号配置对应的下行符号与第一时隙集合TG1中的至少一个时隙的上行符号在时域上不重叠，且第七时隙T7中包括至少一个控制信道监听时机。其中，第八下行符号配置对应的下行符号是由所述第八下行符号配置中的起始下行符号的索引信息以及下行符号的持续符号数信息确定的。TG1是由根据ST2、聚合因子和承载码本的上行信道所在时隙确定的时隙组成的集合。T7为根据ST2、第八下行符号配置中的时隙偏移值信息、聚合因子和承载码本的上行信道所在时隙确定的时隙。
第八下行符号配置与第三下行符号配置不同。可选的，由第八下行符号配置与第三下行符号配置组成所述下行符号配置列表。
有关TG1的确定过程可以参考上面的描述，T7的确定方法可以参考方法1A中的T2的确定方法直接得到，在此不加赘述。
第二类：对下行符号配置列表中的每一个下行符号配置，同时通过比较该下行符号配置在第一时隙定时值子集对应的多个时隙中的有效性确定该下行符号配置是否有效，从而进一步确定由有效的下行符号配置组成的第一时隙定时值子集对应的下行符号配置集合。
在第二类方法中，有三种方法可以用于确定第一下行符号配置集合G1。
方法2A：同时判断与第一时隙定时值子集中的时隙定时值对应的单个下行时隙，确定下行符号配置列表中的下行符号配置的有效性，从而进一步确定由有效的下行符号配 置组成的第一下行符号配置集合G1。
G1不包括所述下行符号配置列表中满足以下条件的第四下行符号配置：
对于第二时隙集合TG2中的每个时隙TG2_T，第四下行符号配置对应的下行符号与TG2_T的上行符号部分或全部重叠，或，TG2_T对应的第四时隙T4中不包括控制信道监听时机。第四下行符号配置对应的下行符号是由第四下行符号配置中的起始下行符号的索引信息以及下行符号的持续符号数信息确定的。第四下行符号配置对应的下行符号与TG2_T的上行符号部分或全部重叠，是指第四下行符号配置对应的下行符号中至少有一个下行符号与时隙TG2_T中的上行符号在时域上重叠，即包括了相同的符号索引。时隙TG2_T对应的第四时隙T4中不包括控制信道监听时机，可以理解为T4中不包括至少一个控制信道监听时机。
TG2中的每个时隙与第一时隙定时值子集中的每个时隙定时值一一对应。具体的，作为第二时隙集合TG2中的任意一个时隙TG2_T，TG2_T可以是根据第一时隙定时值子集中的时隙定时值和承载码本的上行信道所在时隙确定的时隙。具体的，TG2_T的时隙索引可以等于承载码本的上行信道所在时隙的时隙索引减去第一时隙定时值子集中的一个时隙定时值。TG2包括的时隙的个数等于第一时隙定时值子集包括的时隙定时值的个数。例如，设承载码本的上行信道所在时隙的索引为n，第一时隙定时值子集包括的所有时隙定时值为ST1，ST2，ST3和ST4，则第二时隙集合TG2中的时隙对应的时隙索引的集合为{(n-ST1),(n-ST2),(n-ST3),(n-ST4)}。可选的，可以进一步将上述差值对M取模作为TG2中的时隙对应的时隙索引。即TG2中的时隙对应的时隙索引的集合为{(n-ST1)mod M,(n-ST2)mod M,(n-ST3)mod M,(n-ST4)mod M}。有关M的描述可以参考方法1A中对M的相关描述，这里不加赘述。
