Description

HARQ-ACK信息传输方法及装置、通信设备 技术领域
本公开实施例涉及无线通信领域但不限于无线通信领域，尤其涉及一种混合自动重传请求应答(Hybrid Automatic Repeat request acknowledgement，HARQ-ACK)信息传输方法及装置、通信设备。
背景技术
在第五代(5th Generation，5G)新无线(New Radio，NR)中，基站在调度物理下行共享信道(Physical Downlink Shared Channel，PDSCH)资源(配置为PDSCH的通信资源)时，需要为该PDSCH资源传输的数据指示其对应的HARQ-ACK信息的传输资源。
在5G NR非授权信道(NR-Unlicense，NR-U)中提出了一种一次性(one shot)HARQ-ACK反馈机制，用于指示将所有HARQ进程的HARQ-ACK信息一次性反馈。如果基站给用户设备(User Equipment，UE)配置了一次性HARQ-ACK反馈机制，那么UE在每次反馈HARQ-ACK信息时，需要一次反馈所有HARQ进程(不管是对应HARQ-ACK进程的PDSCH资源被调度了还是没调度的)的HARQ-ACK信息。
但是在非授权信道上由于干扰大，用户设备(User Equipment，UE)在进行HARQ-ACK信息的传输时，可能存在着被干扰，导致出错的现象；此时，就会导致不必要的重传或者重传延迟大等传输错误。
发明内容
本公开实施例提供一种HARQ-ACK传输方法及装置、通信设备。

接收基站为所述UE配置使用一次性HARQ-ACK反馈机制时下发的包含预定信息域的高层信令；
基于所述预定信息域携带的传输次数N，在基于所述一次性HARQ-ACK反馈机制对应的N个反馈时机上，接收N次同一个所述HARQ-ACK信息，其中，N为正整数。
本公开实施例第二方面提供一种HARQ-ACK信息传输方法，应用于用户设备(User Equipment，UE)中，包括：
当基站配置所述UE使用一次性HARQ-ACK反馈机制时，接收包含预定信息域的高层信令；
基于所述预定信息域携带的传输次数N，在基于所述一次性HARQ-ACK反馈机制对应的N个反馈时机上，发送N次同一个所述HARQ-ACK信息，其中，N为正整数。
本公开实施例第三方面提供一种触发HARQ-ACK信息传输装置，应用于基站中，包括：
第一发送模块，被配置为当为用户设备UE配置使用一次性HARQ-ACK反馈机制时，下发包含预定信息域的高层信令；
第一接收模块，被配置为基于所述预定信息域携带的传输次数N，在基于所述一次性HARQ-ACK反馈机制对应的N个反馈时机上，接收N次同一个所述HARQ-ACK信息，其中，N为正整数。
本公开实施例第四方面提供一种触发HARQ-ACK信息传输装置，应用于UE中，包括：
第二接收模块，被配置为接收基站为所述UE配置使用一次性HARQ-ACK反馈机制时下发的包含预定信息域的高层信令；
第二发送模块，被配置为基于所述预定信息域携带的传输次数N，在基于所述一次性HARQ-ACK反馈机制对应的N个反馈时机上，发送N次同一个所述HARQ-ACK信息，其中，N为正整数。
本公开实施例第五方面提供一种通信设备，其中，包括：
收发器；
存储器；
处理器，分别与所述收发器及所述存储器连接，用于通过执行存储在所述存储器上的计算机可执行指令，控制收发器的无线信号收发，并实现前述第一方面或第二方面任意技术方案提供的HARQ-ACK传输方法。
本公开实施例第六方面提供一种计算机非瞬间存储介质，其中，所述计算机非瞬间存储介质存储有计算机可执行指令；所述计算机可执行指令被处理器执行后能够实现前述第一方面或第二方面任意技术方案提供的HARQ-ACK信息传输方法。
本公开实施例提供的技术方案，在为UE配置了使用一次性(one shot)HARQ-ACK反馈机制时，在首次HARQ-ACK信息传输失败时，在第2次至第N次中任意一次HARQ-ACK信息传输成功，则基站都能够成功接收到UE上传的HARQ-ACK信息，减少HARQ-ACK信息单次传输失败导致的数据传输错误的现象。在N个反馈时机会接收到同一个HARQ-ACK信息的N次传输。若这N反馈时机，使得一个HARQ-ACK信息在时域上获得分集增益，从而提升了一个HARQ-ACK信息的传输成功率。

请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个UE11以及若干个基站12。
其中，UE11可以是指向用户提供语音和/或数据连通性的设备。UE11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，UE11可以是物联网UE，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网UE的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程UE(remote terminal)、接入UE(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户UE(user equipment，UE)。或者，UE11也可以是无人飞行器的设备。或者，UE11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，UE11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。该无线通信系统可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无 线通信系统可以是支持新空口非授权频谱通信(NR-U，New Radio-Unlicense)的系统。或者该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。
其中，基站12可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Medium Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和UE11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，UE11之间还可以建立E2E(End to End，端到端)连接。在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实 施例不做限定。
如图2所示，本实施例提供一种HARQ-ACK信息传输方法，其中，应用于基站中，包括：
S110：当为UE配置使用一次性HARQ-ACK反馈机制时，下发包含预定信息域的高层信令；
S120：基于所述预定信息域携带的传输次数N，在基于所述一次性HARQ-ACK反馈机制对应的N个反馈时机上，接收N次同一个所述HARQ-ACK信息，其中，所述N为正整。
本实施例提供的HARQ-ACK信息可为：利用非授权信道传输的反馈信息，或利用授权信道传输的反馈信息。
该高层信令可为物理层以上的任意层的信令。在本申请实施例中，该高层信令包括但不限于：MAC层信令和/或无线资源控制(Radio Resource Control，RRC)信令。采用MAC层信令携带激活信令或去激活信令，基站在下发信令时具有更大的灵活性。
其中，所述预定信息域可以携带所述HARQ-ACK信息的传输次数N。N可为正整数。具体的，若确定出当前非授权信道的干扰大，则将N设置大一些，若确定出当前非授权信道的干扰小，则将N设置的小一些。
例如，在物理上行控制信道(Physical Uplink Control Channel，PUCCH)的干扰信号强度大于或等于干扰阈值时，N的取值为大于或等于2的正整数，在PUCCH信道干扰强度小于干扰阈值时，N的取值可为1。若N为1则表示基于一次性(one shot)HARQ-ACK反馈机制触发的HARQ-ACK信息不需要重传。此处的PUCCH信道可为非授权信道或者授权信道。
在N大于或等于2时，N的取值可选为3至10次或者2至3次或2至4次。N的取值范围为2至4或2至3之间的正整数，一方面实现了同一个HARQ-ACK信息的重复传输，另一方面减少了超过4次以上的传输导致的 不必要传输等，减少HARQ-ACK信息传输所产生的不必要的比特开销。
若使用一次性HARQ-ACK反馈机制传输HARQ-ACK信息，则UE会一次性将所有HARQ进程所对应的HARQ-ACK信息传输给基站。例如，若HARQ进程的个数为16个，则使用一次性HARQ-ACK传输HARQ-ACK信息时，则UE会一次性向基站发送16个HARQ进程的HARQ-ACK信息，则基站会接收到UE一次性上报的16个HARQ-ACK信息。例如，HARQ进程的个数为8个，则使用一次性HARQ-ACK传输HARQ-ACK时，则UE会一次性向基站发送8个HARQ进程的HARQ-ACK信息，则基站会接收到UE一次性上报的8个HARQ-ACK信息。
该HARQ-ACK信息可包括：ACK和NACK。ACK指示数据接收成功，NACK指示数据接收失败。
如此，在首次HARQ-ACK信息传输失败时，在第2次至第N次中任意一次HARQ-ACK信息传输成功，则基站都能够成功接收到UE上传的HARQ-ACK信息，减少HARQ-ACK信息单次传输失败导致的数据传输错误的现象。
一个所述反馈时机会进行待传输N次的HARQ-ACK信息的一次传输。如此，N个反馈时机会分别传输HARQ-ACK信息一次。若这N反馈时机在时域上是分离的，则同一个HARQ-ACK信息的N次传输在时域上分离，相对于在时域上集中传输，减少单一时间段内的干扰大导致的N次传输都失败的现象，从而提升了一个HARQ-ACK信息的传输成功率。
而一次性HARQ-ACK反馈机制对应的反馈时机，可以根据调度PDSCH的下行控制信息(Downlink Control Information，DCI)所携带的信息确定。
一个所述反馈时机可为一个PUCCH资源。一个所述PUCCH资源可以进行一次HARQ-ACK信息的传输。
在一些实施例中，所述方法还包括：当确定激活HARQ-ACK信息的重复传输时，下发激活指示，其中，所述激活指示，用于触发所述UE基于所述传输次数发送N次同一个所述HARQ-ACK信息；当确定去激活HARQ-ACK信息的重复传输时，下发去激活指示，其中，所述去激活指示，用于触发UE发送1次一个所述HARQ-ACK信息。
如图3A所示，所述方法还包括：
S111：当确定激活HARQ-ACK信息的重复传输时，下发激活指示；
所述S120还可包括S121；S121：
在HARQ-ACK信息的重复传输被所述激活指示激活后，基于所述预定信息域携带的传输次数N，在基于所述一次性HARQ-ACK反馈机制对应的N个反馈时机上，接收N次同一个所述HARQ-ACK信息。
在一些实施例中，若N大于或等于2的情况下，则HARQ-ACK信息就会有重复传输。若N大于或等于2，则基站确定需要激活HARQ-ACK信息的重复传输，则会下发激活指示。UE接收到该激活指示支护，才会基于N发送基于一次性HARQ-ACK反馈机制所产生的同一个HARQ-ACK信息的N次传输。
在另一些实施例中，若N等于1时，相当于一个HARQ-ACK信息仅会传输一次，此时可以不激活所述重复传输，即不下发所述激活指示。
若下发了激活指示，则基站会在一次性HARQ-ACK反馈机制所对应的N个反馈时机上，接收同一个HARQ-ACK信息N次。
如图3B所示，所述方法还包括：
S112：当确定去激活HARQ-ACK信息的重复传输时，下发去激活指示；该去激活指示，用于指示所述UE去激活所述HARQ-ACK信息的重 复传输，即该去激活指示，用于指示UE不用重复传输HARQ-ACK信息。例如，激活指示用于指示UE进行一个HARQ-ACK信息的N次重复传输。去激活指示用于去除激活指示激活的一个HARQ-ACK信息的N次重复传输。在一些实施例中，UE在接收到去激活指示之后，不会在按照N进行一个HARQ-ACK信息的重复传输，但是会一个HARQ-ACK信息还是会传输一次。
所述S120还可包括S122；S122：在所述重复传输被所述去激活指示去激活后，在基于所述一次性HARQ-ACK反馈机制对应的1个反馈时机上，接收1次一个所述HARQ-ACK信息。
在一些实施例中，所述S111可包括：通过媒体访问控制MAC层信令下发所述激活指示或去激活指示。
在本申请实施例中，激活指示可以携带在MAC信令中，例如，携带在MAC控制单元(Control Element，CE)中。
在另一些实施例中，可以物理层信令(例如，下行控制信息)和/或MAC信令中设置一个信息域来携带所述激活指示。该信息域的特定比特值时为携带有所述激活指示，携带所述特定比特值以外的比特值时可认为未下发激活指示或者认为基站下发了去激活指示。此处的去激活指示为指示同一个HARQ-ACK信息不需要传输N次，例如，仅需传输一次即可。
在一些实施例中，携带有所述HARQ-ACK信息的HARQ-ACK码本包括：N个子码本；一个所述子码本携带一个所述HARQ-ACK信息。
图4A和图4B为一个所述HARQ-ACK码本，当N等于3时，一个所述HARQ-ACK码本包含3个子码本。一个子码本可以用于携带一个基于一次性HARQ-ACK反馈机制触发的所有HARQ进程的HARQ-ACK。在图4A和图4B中一个子码本包含8个比特。
在图4A中为了区分不同的子码本，子码本之间采用串接方式进行展示。而在HARQ-ACK码本中各个比特的方式可能如图4B所示，图4B中表示位于HARQ-ACK码本左侧的比特为高位比特，而位于右侧的比特为低位比特。可见第1子码本所占用的比特位于第2个子码本及第3个子码本所占用的比特之前。
例如，HARQ进程共用S个，则一个HARQ-ACK信息包括这S个HARQ进程的HARQ-ACK。若一个HARQ进程的HARQ-ACK消耗1个比特来指示传输成功或失败，则一个HARQ-ACK信息供需要S个比特，则HARQ-ACK码本中的一个子码本至少包含S个比特。
在一些实施例中，所述子码本的编号可以从HARQ-ACK码本的高位向低位方向排序，也可以是从HARQ-ACK码本的低位向高位方向进行排序。
例如，如图5所示，从HARQ-ACK码本的高位向低位方向排序时，第1个子码本占据的HARQ-ACK码本中的比特，为第2个子码本占据的HARQ-ACK码本中的比特的高位。例如，一个16个比特构成的N＝2的HARQ-ACK码本当前携带的比特值为“0000000011110000”，“00000000”为“11110000”的高位。“00000000”为“11110000”分别对应了HARQ-ACK码本中的两个子码本。且“00000000”由第1个子码本携带，且“11110000”由第二子码本携带。
在一些实施例中，一个所述HARQ-ACK信息在第X次传输时，由HARQ-ACK码本的第N+1-X个子码本携带，其中，X为小于N或等于N的正整数。
一个HARQ-ACK信息在第X次传输，则由当前传输的HARQ-ACK码本的第N+1-X个子码本携带的话，则一个HARQ-ACK信息的首次传输由HARQ-ACK码本的最后一个子码本携带，且一个HARQ-ACK信息 的最后一次传输由HARQ-ACK码本的第1个子码本传输。
在本申请实施例中HARQ-ACK码本中子码本可以按照从高位向低位排序时，若一个HARQ-ACK信息在第X次传输，则由当前传输的HARQ-ACK码本的第N+1-X个子码本携带的传输方式传输时，则非首次传输的HARQ-ACK信息携带在一个HARQ-ACK码本中的较高位。若高位先传输的情况下，则基站会先接收到非首次传输的HARQ-ACK信息，且结合之前传输联合解码，可以更快的解码出在线传输的HARQ-ACK信息，从而减少在先调度的PDSCH传输的反馈信息的解调延时，从而可以尽快的实现重传。
在刚开始起始传输时，可能存在一种情况当前的一次性HARQ-ACK反馈机制触发的反馈时机的个数小于N，则对应的形成的HARQ-ACK信息的总个数也小于N，此时，一个HARQ-ACK码本中的有部分子码本是没有可供携带的HARQ-ACK信息。在本申请实施例中这一部分子码本可以携带预定比特序列。该预定比特序列可为全“1”序列、全“0”序列或者按照预定方式组合形成的“0”及“1”的组合序列。例如，以一个子码本为8个比特进行举例说明，则该预定比特序列可以为以下任意一个：
“00000000”、“11111111”、“11000011”、“10101010”、“11001100”及“10000001”。
总之，在起始PDSCH传输时，若待发送的所述HARQ-ACK信息的个数Y小于N，HARQ-ACK码本中的第1个至第N-Y个子码本携带预定比特序列。
如图5所示，在一个HARQ-ACK码本包含两个子码本，这两个子码本分别是第一子码本和第二子码本。
在HARQ-ACK信息的起始传输时，可能当前仅有一次一次性HARQ-ACK反馈机制对应的一个反馈时机所产生的一个HARQ-ACK信 息。该HARQ-ACK信息为“11111100”，将“11111100”携带在HARQ-ACK码本的第2个子码本中，而空出来的第1个子码本携带的是全“0”序列。在已经产生了第二个HARQ-ACK信息时，则在HARQ-ACK码本中的第1个子码本中携带首个HARQ-ACK信息，而在第2个子码本中携带第2次产生的HARQ-ACK信息。此时，HARQ-ACK码本的第1个子码本携带的内容为“11111100”，而第2个子码本携带的内容为“11111000”。
在一些实施例中，在所述HARQ-ACK码本中第n个HARQ-ACK信息所在的子码本，位于第n+1HARQ-ACK信息所在的子码本之前，其中，n为正整数。
在本申请实施中，第n个HARQ-ACK信息所在的子码本位于第n+1HARQ-ACK信息所在的子码本之前，即第n个HARQ-ACK信息所在的子码本位于HARQ-ACK码本的高位，而第n个HARQ-ACK信息所在的子码本位于HARQ-ACK的低位。
在一些实施例中，所述HARQ-ACK码本包含的比特数为：
N*N ID*BofPerID；其中，所述N ID为HARQ进程数；所述BofPerID为一个所述HARQ进程的所述HARQ-ACK信息占用的比特数；一个所述子码本的比特数为：N ID*BofPerID。
在一些实施例中，若一个HARQ进程可对应于一个或多个HARQ-ACK。例如，一个HARQ进程分配给一个TB，若按照一个TB完成传输进行一次反馈，且一个TB对应于一个HARQ-ACK，则一个HARQ进程所对应的HARQ-ACK仅占用一个比特。
一个TB可包含多个码块(Code Block，CB)，而多个CB可以组成码块组(Code Block Group，CBG)，使得一个TB包含多个CBG。若一个CBG对应于一个HARQ-ACK，则一个HARQ进程所占用的比特数等于或大于2。
一个所述子码本的比特数为N ID*BofPerID，即一个HARQ-ACK信息所消耗的比特数为N ID*BofPerID。
在一些实施例中，所述方法还包括：
当所述预定信息域未携带有所述传输次数时，在基于所述一次性HARQ-ACK反馈机制对应的一个反馈时机上，接收一次一个所述HARQ-ACK信息。
若高层信令预定信息域未携带有所述传输次数时，则基站和UE默认一个HARQ-ACK信息仅传输一次。
在一些实施例中，所述预定信息域可包括两个部分，分别是第一部分和第二部分，第一部分为指示比特，指示所述第二部分是否有携带所述传输次数。如此，该预定信息域还可以复用为指示其他任意信息。当然所述预定信息域是否携带有所述传输次数，还可以由所述预定信息域以外的其他信息域内的指示比特进行指示。
如图6所示，本实施例提供一种HARQ-ACK信息传输方法，包括：
S210：接收基站为所述UE配置使用一次性HARQ-ACK反馈机制时下发的包含预定信息域的高层信令；
S220：基于所述预定信息域携带的传输次数N，在基于所述一次性HARQ-ACK反馈机制对应的N个反馈时机上，发送N次同一个所述HARQ-ACK信息，其中，N为正整数。
本申请实施例中的HARQ-ACK信息传输方法可应用于UE中。该UE包括但不限于机械类通信(Machine Type Communication，MTC)设备或者物理网(Internet of Things，IoT)设备或者常规的长期演进(Long Term Evolution，LTE)设备。此处的常规的LTE设备可包括：手机或车载设备等。
在基站配置UE使用一次性HARQ-ACK反馈机制时，UE需要接收 携带有预定信息域的高层信令，此处的高层信令包括但不限于RRC信令和/或MAC层信令。
在接收到携带有预定信息域的高层信令之后，会基于该预定信息域携带的传输次数N，在一次性HARQ-ACK反馈机制对应的N个反馈时机上，发送一个HARQ-ACK信息N次。
在一些实施例中，如图7所示，所述方法还包括：
S211：接收激活指示；
所述S220可包括S221；S221：在HARQ-ACK信息的重复传输被所述激活指示激活后，基于所述预定信息域携带的传输次数N，在基于所述一次性HARQ-ACK反馈机制对应的N个反馈时机上，发送N次同一个所述HARQ-ACK信息。
只有在激活HARQ-ACK信息的重复传输时，才会基于该N进行同一个HARQ-ACK信息的N次传输。
在一些实施例中，所述方法还包括：
S212：接收去激活指示；该去激活指示用于指示UE去激活所述HARQ-ACK信息的重复传输。例如，可如图7所示，所述方法还包括：
S222：在重复传输被所述去激活指示去激活后在基于所述一次性HARQ-ACK反馈机制对应的1个反馈时机上，发送1次一个所述HARQ-ACK信息。
在一些实施例中，所述S211可包括：通过接收MAC层信令获取所述激活指示或所述去激活指示。
在一些实施例中，携带有所述HARQ-ACK信息的HARQ-ACK码本包括：N个子码本；一个所述子码本携带一个所述HARQ-ACK信息。

在一些实施例中，当待发送的所述HARQ-ACK信息的个数Y小于N个时，则所述HARQ-ACK码本的第1个子码本至第N-Y个子码本携带预定比特序列。
在一些实施例中，在所述HARQ-ACK码本中第n个HARQ-ACK信息所在的子码本，位于第n+1 HARQ-ACK信息所在的子码本之前，其中，n为正整数。
在一些实施例中，所述HARQ-ACK码本包含的比特数为：
N*N ID*BofPerID；其中，所述N ID为HARQ进程数；所述BofPerID为一个所述HARQ进程的所述HARQ-ACK信息占用的比特数；一个所述子码本的比特数为：N ID*BofPerID。
如图8所示，本实施例所述的方法还包括：
S230：当所述预定信息域未携带有所述传输次数时或者接收到去激活指示时，在基于所述一次性HARQ-ACK反馈机制对应的一个反馈时机上，发送一次一个所述HARQ-ACK信息。
在预定信息域未携带有传输次数或接收到所述去激活指示时，则一个HARQ-ACK信息在一次性HARQ-ACK反馈机制所对应的一个反馈时机上发送一次即可。如此，基站会在一次性HARQ-ACK反馈机制所对应的一个反馈时机上接收到一次一个HARQ-ACK信息。
若UE之前接收到激活HARQ-ACK信息的重复传输的激活指示，则可能基站会再次下发去激活指示，指示不再使用N进行HARQ-ACK信息的重复传输。
该预定信息域未携带有传输次数包含以下之一：
预定信息域携带的全“0”比特；
若预定信息域不包含携带所述传输次数的子域；
预定信息域中指示不同子域携带内容的子域指示未携带所述传输次数。在后两种方式中，预定信息域包括多个子域，不同的子域指示内容不同。

在一些实施例中，所述装置还包括：
当所述预定信息域未携带有所述传输次数时，在基于所述一次性HARQ-ACK反馈机制对应的一个反馈时机上，发送一次一个所述HARQ-ACK信息。
以下结合上述任意实施例提供两个具体示例：
示例1：
当UE被配置为使用一次性HARQ-ACK反馈机制传输HARQ-ACK 信息时，基站还可以为UE配置是否重复传输HARQ-ACK信息，或者重复传输HARQ-ACK信息的次数。
例如，基站进行上行配置的方式包含：
基站通过RRC层信令配置重复传输HARQ-ACK信息的次数，
当传输次数为0时，表示只有首次传输，没有重复传输；
当次数为不小于2的N时表示除了首次传输外，该HARQ-ACK信息,还将在后续的N-1个反馈时机对应的PUCCH资源上分别传输N-1次HARQ-ACK信息。
基站通过RRC层信令配置传输次数，并通过MAC层信令激活和去激活HARQ-ACK信息的重复传输。
当RRC层配置的传输次数为N，且UE被MAC层信令激活了重复传输HARQ-ACK信息时，UE将HARQ-ACK首次传输后，还会在后续的N-1个反馈时机对应的PUCCH资源上分别传输N-1次同一个HARQ-ACK信息。
如果UE没有被MAC层信令激活HARQ-ACK信息的重复传输HARQ-ACK信息，或者被MAC层信令去激活HARQ-ACK信息的重复传输HARQ-ACK信息，UE将只传输一次HARQ-ACK信息，不会重复传输该HARQ-ACK信息。
如果UE没有收到重复传输的RRC配置信令，则UE将只传输一次HARQ-ACK信息，不会重复传输该HARQ-ACK信息。
示例2：
在激活基于一次性HARQ-ACK反馈机制所长生的HARQ-ACK信息的情况下，假定基站配置的最大下行进程数为8，配置了UE使用一次性HARQ-ACK反馈机制，且重复次数N＝2。假定每个下行进程的PDSCH传输对应于1比特的HARQ-ACK。
参考图5所示，在基于一次性HARQ-ACK反馈机制产生的第一次HARQ-ACK信息的传输时，由于在此之前还没有PDSCH的传输，所以该HARQ-ACK反馈信息中对应于重复HARQ-ACK信息部分的8比特全为NACK(以0表示)。
在第二次反馈HARQ-ACK信息时，需要重复第一次的HARQ-ACK信息且携带当前次(即第二次)的HARQ-ACK信息。第二次传输的HARQ-ACK反馈中包含前一组PDSCH(从HARQ ID 0～5)的HARQ-ACK信息(对应于图中的重复HARQ-ACK)，还要包含当前的PDSCH(从HARQ ID 0～4)的HARQ-ACK信息(对应于图中的当前HARQ-ACK)。
在这种重复传输HARQ-ACK信息方式下，UE上报一次HARQ-ACK信息所消耗比特数等于：重复次数*HARQ进程数*每个HARQ进程的HARQ-ACK所消耗的比特数。且对应于当前一组PDSCH传输的HARQ-ACK信息位于本次上报的HARQ-ACK码本的最后。
