请参考图2，其示出了本申请一个示例性实施例提供的反馈应答信息发送方法的流程图。本实施例以该方法应用于图1所示的终端中来举例说明。该方法包括：
步骤202，终端确定第一比特数量，第一比特数量是通过目标上行信道传输UCI时的最大比特数量，目标上行信道用于传输至少两个成员载波对应的反馈应答信息；
目标上行信道是PUCCH或者PUSCH。
至少两个成员载波(Component Carrier，CC)是通过CA技术向终端发送和/或接收数据的载波。至少两个成员载波可以是同一个频带内的连续载波，也可以是同一个频带内的不连续载波，还可以是不同频带内的载波。
可选地，当成员载波采用TB进行数据传输时，反馈应答信息包括传输块级反馈应答信息；当成员载波采用CBG进行数据传输时，反馈应答信息包括编码块组级反馈应答信息。
可选地，第一比特数量是接入网设备向终端配置的，或者，第一比特数量是预定义的，本实施例对第一比特数量的确定方式不加以限定。
步骤204，当待传输的反馈应答信息的比特数量大于第一比特数量时，终端对至少两个成员载波中的目标成员载波对应的反馈应答信息进行压缩，得到压缩后的反馈应答信息；
可选地，终端还根据接收到的下行数据数量，确定待传输的反馈应答信息的比特数量。当成员载波被配置为TB级传输时，反馈应答信息的比特数量与TB数量对应；当成员载波被配置为CBG级传输时，反馈应答信息的比特数量与CBG数量对应。
目标成员载波是采用载波聚合技术的至少两个成员载波中的全部或部分载波。可选地，目标成员载 波的反馈应答信息需要进行压缩处理，非目标成员载波的反馈应答信息不需要进行压缩处理。
对反馈应答信息进行压缩，是指将多个单位的下行数据的反馈应答信息压缩至同一个比特，采用一个比特代表多个单位的下行数据的反馈应答信息，单位是码字、TB和CBG中的至少一种。当该比特的取值为第一取值(比如1)时，代表多个单位的下行数据均接收成功；当该比特的取值为第二取值(比如0)时，代表多个单位的下行数据中存在至少一个单位的下行数据接收失败。
其中，压缩后的反馈应答信息的比特数量小于或等于第一比特数量。压缩后的反馈应答信息，是对压缩前的反馈应答信息中的全部比特或一部分比特进行压缩后得到的。
当待传输的反馈应答信息的比特数量不大于第一比特数量时，终端不对待传输的反馈应答信息进行压缩。
步骤206，终端通过目标上行信道发送压缩后的反馈应答信息。
可选地，在目标上行信道上用于传输反馈应答信息的上行资源是由接入网设备预先配置的，或者预定义的。
终端将压缩后的反馈应答信息携带在UCI中，通过目标上行信道上的上行资源发送给接入网设备。可选地，UCI采用预配置的PUCCH format。
示意性的，终端通过PUCCH向接入网设备发送压缩后的反馈应答信息。
综上所述，本实施例提供的方法，通过当待传输的反馈应答信息的比特数量大于第一比特数量时，终端对被聚合的至少两个成员载波中的目标成员载波对应的反馈应答信息进行压缩，得到压缩后的反馈应答信息。由于压缩后的反馈应答信息不大于第一比特数量，所以使得终端能够使用有限的比特数量，向接入网设备一次性发送被聚合的至少两个成员载波的反馈应答信息。
在基于图2实施例的一个可选的实施例中，当待传输的反馈应答信息的比特数量大于第一比特数量时，终端从至少两个成员载波中确定出目标成员载波，该目标成员载波包括但不限于如下六种载波中的至少一种：
·辅成员载波；
·配置为编码块组级传输的成员载波；
·支持的编码块组数量达到第一条件的第一成员载波，第一条件包括大于第一阈值或排序在前n位，n为整数；例如，第一阈值是2个CBG或4个CBG；又比如，按照支持的编码块组数量由多到少的顺序，排序在前1位或前2位的成员载波。
·所包含的下行传输资源数量达到第二条件的第二成员载波，第二条件包括小于第二阈值或排序在后m位；例如，第二阈值是1个符号、1个时隙中的时频资源或2个时隙中的时频资源；又比如，按照所包含的下行传输资源数量由少到多的顺序，排序在前1位或前2位的成员载波。
·在压缩后的比特数量不大于第一比特数量的多个候选压缩方案中，第一候选压缩方案中被压缩的成员载波，第一候选压缩方案是多个候选压缩方案中被压缩的成员载波数量最多的方案；
·在压缩后的比特数量不大于第一比特数量的多个候选压缩方案中，第二候选压缩方案中被压缩的成员载波，第二候选压缩方案是多个候选压缩方案中被压缩的成员载波数量最少的方案。
在满足压缩后的反馈应答信息不大于第一比特数量的前提下，终端可以将上述六种成员载波中的至少一种载波，确定为目标成员载波。然后对目标成员载波对应的反馈应答信息进行压缩。
可选地，上述“排序”是指按照数量由大到小排序、按照数量由小到大排序、按照载波编号由高到低排序、按照载波序号由低到高排序中的任意一种。
可选地，当存在多种候选成员载波时，终端按照预设的优先级顺序，选择多种候选成员载波中的全部或一部分载波，确定为目标成员载波。
可选地，成员载波是指主小区或辅小区的单个下行载波。
主小区(Primary Cell，PCell)是在主载频上运行的小区，UE在执行初始连接建立、或初始连接重建、或在切换过程中被指明为主小区。
辅小区(Secondary Cell，SCell)是在辅载频上运行的小区，配置该小区用于在无线资源控制(Radio Resource Control，RRC)。
一个终端可以连接1个主小区和多个辅小区。比如，辅小区可以是1至4个。
被聚合的至少两个成员载波中，包括主成员载波(Primary Component Carrier，PCC)和辅成员载波(Secondary Component Carrier，SCC)。对应的，一次载波聚合过程中，可以有1个主成员载波和多个辅成员载波。比如，辅成员载波是1至4个。本申请实施例对辅小区和辅成员载波的数量不加以限定。
下面结合一个具体的实施场景进行示意性说明。参考图3，假设被聚合的成员载波包括：PCC、SCC1和SCC2。其中，PCC被配置为CBG级传输，使用单码字传输模式，以及支持的CBG最大数量为4个；SCC 1被配置为CBG级传输，使用单码字传输模式，以及支持的CBG最大数量为2个；SCC 2被配置 为TB级传输，使用双码字传输模式。
当下行时隙(slot)n和下行时隙n+1对应的反馈应答信息通过PUCCH信道上的同一个UCI复用传输时，待传输的反馈应答信息如图4所示。其中，待传输的反馈应答信息共16个比特，包括：PCC在时隙n的4个CBG的反馈应答信息，共4bit；PCC在时隙n+1的4个CBG的反馈应答信息，共4bit；SCC1在时隙n的2个CBG的反馈应答信息，共2bit；SCC1在时隙n+1的2个CBG的反馈应答信息，共2bit；SCC2在时隙n的2个TB的反馈应答信息，共2bit；SCC2在时隙n+1的2个TB的反馈应答信息，共2bit。
也即，若不对反馈应答信息进行压缩，则需要16bit的上行资源来传输本次的反馈应答信息。
在基于图2实施例的一个可选的实施例中，目标成员载波包括辅成员载波。在压缩反馈应答信息之前还包括步骤2031，如图5所示：
步骤202，确定第一比特数量；

可选地，终端以压缩后的反馈应答信息不大于第一比特数量为目标，按照辅成员载波的编号由大到小的顺序，确定至少一个辅成员载波是目标成员载波；或者，终端按照辅成员载波的编号由小到大的顺序，确定至少一个辅成员载波。
可选地，终端按照辅成员载波的编号由小到大的顺序，计算前i个辅成员载波的反馈应答信息被压缩后，压缩后的反馈应答信息的比特数量是否等于第一比特数量，i的初始值为1；若等于第一比特数量，则将前i个辅成员载波确定为目标成员载波；若大于第一比特数量，则令i＝i+1，再次执行计算前i个辅成员载波的反馈应答信息被压缩后，压缩后的反馈应答信息的比特数量是否等于第一比特数量的步骤。本申请对压缩方式不加以限定，终端也可以一次性将待传输的反馈应答信息的比特数量压缩至等于第一比特数量。

可选地，在辅成员载波被确定为目标成员载波后，若该载波配置为TB级传输，将至少两个TB对应的反馈应答信息压缩为同一个比特，示意性的，将属于同一个码字的至少两个TB所对应的反馈应答信息压缩为同一个比特；若该载波配置为CBG级传输，将至少两个CBG对应的反馈应答信息压缩为同一个比特，示意性的，将属于同一个TB的至少两个CBG对应的反馈应答信息压缩为同一个比特。比如一个TB包括CBG1、CBG2、CBG3和CBG4，可以将CBG1和CBG2的2比特反馈应答信息压缩为同一个比特，可以将CBG3和CBG4的2比特反馈应答信息压缩为同一个比特；或者，将CBG1、CBG2、CBG3和CBG4的2比特反馈应答信息压缩为同一个比特。
示意性的，在将至少两个TB对应的反馈应答信息压缩为同一个比特时，若至少两个TB对应的反馈应答信息均为ACK，则压缩后的比特也为ACK；若至少两个TB对应的反馈应答信息存在至少一个NACK，则压缩后的比特为NACK。
示意性的，在将至少两个CBG对应的反馈应答信息压缩为同一个比特时，若至少两个CBG对应的反馈应答信息均为ACK，则压缩后的比特也为ACK；若至少两个CBG对应的反馈应答信息存在至少一个NACK，则压缩后的比特为NACK。

综上所述，本实施例提供的方法，通过将至少一个辅成员载波确定为目标成员载波，对目标成员载波对应的反馈应答信息进行压缩，使得压缩后的反馈应答信息不大于第一比特数量，能够优先保证主成员载波中的TB或CBG的反馈应答信息的正常传输，提高主成员载波的HARQ传输效率。

步骤206，通过目标上行信道发送压缩后的反馈应答信息。
终端通过PUCCH或PUSCH向接入网设备发送压缩后的反馈应答信息。
在一个结合图3的具体例子中，如图8所示，假设终端确定的第一比特数量为8比特，则终端确定PCC和SCC1为目标成员载波；终端对PCC对应的CBG级ACK/NACK进行压缩，使得PCC中的1个TB(含4个CBG)对应1个比特的反馈应答信息，对SCC1对应的CBG级ACK/NACK进行压缩，使得SCC中的1个TB(含2个CBG)对应1个比特的反馈应答信息。
综上所述，本实施例提供的方法，终端优先对支持的CBG数量的成员载波的ACK/NACK进行压缩，使得支持TB级传输的成员载波的反馈应答信息不需要压缩，保障了支持TB级传输的成员载波的传输效率。
在基于图2实施例的一个可选的实施例中，目标成员载波包括支持的编码块组数量达到第一条件的第一成员载波。在压缩反馈应答信息之前还包括步骤2033，如图9所示：
步骤202，确定第一比特数量；

在基于图2实施例的一个可选的实施例中，目标成员载波包括第一候选压缩方案中被压缩的成员载波。在压缩反馈应答信息之前还包括步骤2034，如图16所示：

-将PCC的两个TB对应的反馈应答信息压缩为同一个比特，将SCC1的三个TB对应的反馈应答信息压缩为同一个比特，如图17所示；
-将SCC2的四个TB对应的反馈应答信息压缩为同一个比特，如图18所示。
由于图17的候选压缩方案中被压缩的载波数量为2，图18的候选压缩方案中被压缩的载波数量为1，因此终端将图17的候选压缩方案确定为第一候选压缩方案，将第一候选压缩方案中被压缩的成员载波确定为目标成员载波，对目标成员载波PCC和SCC1中反馈应答信息进行压缩。

步骤204，对目标成员载波对应的反馈应答信息进行压缩，得到压缩后的反馈应答信息；
可选地，在第二候选压缩方案中被压缩的成员载波被确定为目标成员载波后，若该成员载波配置为TB级传输，终端可以将至少两个TB对应的反馈应答信息压缩为同一个比特，示意性的，将属于同一个码字的至少两个TB所对应的反馈应答信息压缩为同一个比特；若该成员载波配置为CBG级传输，将至少两个CBG对应的反馈应答信息压缩为同一个比特，示意性的，将属于同一个TB的至少两个CBG对应的反馈应答信息压缩为同一个比特。
示意性的，在将至少两个TB对应的反馈应答信息压缩为同一个比特时，若至少两个TB对应的反馈 应答信息均为ACK，则压缩后的比特也为ACK；若至少两个TB对应的反馈应答信息存在至少一个NACK，则压缩后的比特为NACK。
示意性的，在将至少两个CBG对应的反馈应答信息压缩为同一个比特时，若至少两个CBG对应的反馈应答信息均为ACK，则压缩后的比特也为ACK；若至少两个CBG对应的反馈应答信息存在至少一个NACK，则压缩后的比特为NACK。
步骤206，通过目标上行信道发送压缩后的反馈应答信息。
终端通过PUCCH或PUSCH向接入网设备发送压缩后的反馈应答信息。
在一个结合图10的具体例子中，假设终端确定的第一比特数量为6比特，则以压缩后的反馈应答信息等于第一比特数量为目标时，存在两种候选压缩方案：
-将PCC的两个TB对应的反馈应答信息压缩为同一个比特，将SCC1的三个TB对应的反馈应答信息压缩为同一个比特，如图15所示；
-将SCC2的四个TB对应的反馈应答信息压缩为同一个比特，如图16所示。
由于图17的候选压缩方案中被压缩的载波数量为2(PCC+SCC1)，图18的候选压缩方案中被压缩的载波数量为1(SCC2)，因此终端将图18的候选压缩方案确定为第二候选压缩方案，将第二候选压缩方案中被压缩的成员载波确定为目标成员载波，对目标成员载波SCC2中反馈应答信息进行压缩。
综上所述，本实施例提供的方法，终端优先对尽可能少的成员载波进行压缩，可以对传输有较小数量的TB或CBG的成员载波的反馈应答信息进行优先反馈，从而保证传输有较小数量的TB或CBG的成员载波的传输效率。
上述图5、图7、图9、图12、图14、图16、图19均以目标成员载波是六种成员载波中的一种来举例说明，但上述五个实施例中的至少两个实施例还可以自由组合实施。比如，终端将辅成员载波和第一成员载波确定为目标成员载波；又比如，终端将辅成员载波和第二成员载波确定为目标成员载波；又比如，终端将第一成员载波和第二成员载波确定为目标成员载波等，本申请不一一赘述。可选地，在存在至少两种类型的成员载波作为候选成员载波时，每种类型对应有各自的优先级，终端选择优先级较高的候选成员载波作为目标成员载波。

请参考图21，其示出了本申请一个示例性实施例提供的反馈应答信息接收方法的流程图。本实施例以该方法应用于图1所示的接入网设备中来举例说明。该方法包括：
步骤301，确定第一比特数量；
第一比特数量是终端通过目标上行信道传输上行控制信令时的最大比特数量，目标上行信道用于传输至少两个成员载波对应的反馈应答信息。
可选地，第一比特数量是接入网设备向终端配置的，接入网设备根据历史配置情况获取该终端的第一比特数量；或者，第一比特数量是预定义的，接入网设备获取该预定义的第一比特数量，本实施例对第一比特数量的确定方式不加以限定。
步骤302，当该终端的待传输的反馈应答信息的比特数量大于第一比特数量时，通过目标上行信道接收终端发送的压缩后的反馈应答信息；
可选地，接入网设备还根据向该终端发送的下行数据数量，确定待传输的反馈应答信息的比特数量。当成员载波被配置为TB级传输时，反馈应答信息的比特数量与TB数量对应；当成员载波被配置为CBG级传输时，反馈应答信息的比特数量与CBG数量对应。其中，压缩后的反馈应答信息是终端对至少两个成员载波中的目标成员载波对应的反馈应答信息进行压缩后得到的，且压缩后的反馈应答信息的比特数量不大于第一比特数量。
当待传输的反馈应答信息的比特数量大于第一比特数量时，接入网设备通过目标上行信道接收终端发送的压缩后的反馈应答信息。
当待传输的反馈应答信息的比特数量不大于第一比特数量时，接入网设备通过目标上行信道接收终端发送的未经压缩的反馈应答信息。
可选地，在目标上行信道上用于传输反馈应答信息的上行资源是由接入网设备预先向终端配置的， 或者预定义的。
接入网设备通过在目标上行信道上的上行资源接收终端发送的UCI，从该UCI中获取压缩后的反馈应答信息。可选地，该UCI采用预配置的PUCCH format。
步骤303，根据压缩后的反馈应答信息确定至少两个成员载波对应的反馈应答信息；
接入网设备按照与终端相同的方式确定目标成员载波，且根据与终端相同的方式确定目标成员载波的反馈应答信息的压缩方式。
对于压缩后的反馈应答信息中的第i个比特，接入网设备确定该第i个比特是非目标成员载波对应的比特，还是目标成员载波对应的比特。
当该第i个比特是非目标成员载波对应的比特时，该比特是未经过压缩的反馈应答信息，用于反馈非目标成员载波中的1个单位(TB、码字、CBG中的较小者)的下行数据的反馈应答信息。当该反馈应答信息是ACK时，接入网设备确认终端成功接收该下行数据；当该反馈应答信息是NACK时，接入网设备确认终端未成功接收该下行数据，接入网设备可以对该下行数据重传。
当该第i个比特是目标成员载波对应的比特时，该比特是经过压缩的反馈应答信息，用于反馈目标成员载波中的至少2个单位的下行数据(TB、码字、CBG中的较小者)的反馈应答信息。当该反馈应答信息是ACK时，接入网设备确认终端成功接收该至少2个单位的下行数据；当该反馈应答信息是NACK时，接入网设备确认终端未成功接收该至少2个单位的下行数据，接入网设备可以对该至少2个单位的下行数据进行重传。
综上所述，本实施例提供的方法，通过当待传输的反馈应答信息的比特数量大于第一比特数量时，终端对被聚合的至少两个成员载波中的目标成员载波对应的反馈应答信息进行压缩，得到压缩后的反馈应答信息。由于压缩后的反馈应答信息不大于第一比特数量，所以使得终端能够使用有限的比特数量，向接入网设备一次性发送被聚合的至少两个成员载波的反馈应答信息。
需要补充说明的是，接入网设备确定目标成员载波以及目标成员载波的反馈应答信息的压缩方式与终端对应一致，可以参考上述图3至图20的实施例，本文不再赘述。
还需要补充说明的是，第一比特数量可以由接入网设备通过高层信令和/或动态信令向终端进行配置。可选地，接入网设备预先会为终端针对不同PUCCH format分别配置其能够承载的UCI的最大编码速率(编码速率越低对应的上行覆盖半径越大，终端发送功率受限的概率越低)。其次，接入网设备还通过高层信令向终端配置在目标上行信道上的多个UCI可用资源，该UCI可用资源使用时域、频域和码域中的至少一种方式进行指示；然后，接入网设备还通过动态信息向终端配置本次使用的UCI可用资源，本次使用的UCI可用资源是多个UCI可用资源中的一个。终端根据最大编码速率和本次使用的UCI可用资源确定本次传输的上行控制信令UCI的最大比特数量。
