Description

传输PUCCH的方法及装置 技术领域
本申请涉及无线通信领域，尤其涉及传输物理上行控制信道(physical uplink control channel，PUCCH)的方法及装置。
背景技术
在通信系统中，网络设备与终端通信之前，会为终端配置至少一个PUCCH组(PUCCH group)。每个PUCCH组包括多个载波，每个载波与一个小区(cell)对应。对于时分双工(time division duplex，TDD)系统，一个载波的帧格式可以包括上行时隙、下行时隙或灵活时隙中的至少一种。上行时隙用于传输上行数据。下行时隙用于传输下行数据。灵活时隙既可以传输上行数据也可以传输下行数据。
终端可以在上行时隙或灵活时隙上向网络设备发送PUCCH。PUCCH可以承载混合自动重复应答(hybrid automatic repeat request acknowledgement，HARQ-ACK)信息等上行控制信息(uplink control information，UCI)。目前PUCCH只能在PUCCH组中一个预设的载波上传输。若网络设备为该载波配置的帧格式中，下行时隙较多，上行时隙或灵活时隙较少，则终端需要等待较长的时间才能发送一次PUCCH。为了解决终端不能及时发送PUCCH的问题，提出了PUCCH可以在PUCCH组中除了预设的载波之外的载波上传输。那么终端如何在PUCCH组中的载波中确定最终用于传输PUCCH的载波是一个亟需解决的问题。
发明内容
本申请提供传输PUCCH的方法及装置，可以在PUCCH组中的载波中确定最终用于传输PUCCH的载波。
为达到上述目的，本申请的实施例采用如下技术方案：

在本申请实施例中，传输PUCCH的方法的执行主体的具体结构，本申请实施例并未特别限定，只要能够实现本申请实施例的提供的方法即可。例如，本申请实施例提供的传输PUCCH的方法的执行主体可以是网络设备，或者为应用于网络设备中的部件，例如，芯片，本申请对此不进行限定。或者，本申请实施例提供的传输PUCCH的方法的执行主体可以是终端，或者为应用于终端中的部件，例如，芯片，本申请对此不进行限定。下述实施例以传输PUCCH的方法的执行主体分别为网络设备、终端为例进行描述。
可以理解的，本申请中以“载波”来举例说明的地方，其中的“载波”可以和“小区”互相替换，例如，“多个载波”可以用“多个小区”替换，在此不再赘述。
如图3所示，为本申请实施例提供的一种传输PUCCH的方法，该传输PUCCH的方法包括S301-S305。
S301：网络设备获取具备传输PUCCH能力的M个载波。
其中，网络设备可以是图1所示的通信系统10中的网络设备，例如，网络设备101。M个载波可以包括在PUCCH组中，M为大于1的整数。M个载波可以位于同一频段(band)，也可以位于不同频段。具备传输PUCCH能力的载波可以理解为PUCCH可以在该载波上传输。
其中，上述PUCCH组可以是协议定义的，也可以是网络设备配置的。以上述PUCCH组是网络设备配置的为例，网络设备可以为终端配置PUCCH组，并向终端发送用于指示该PUCCH组的指示信息。这样终端接收到该指示信息后，就可以根据该指示信息确定该PUCCH组中包括哪些载波。
其中，终端可以是图1所示的通信系统10中的任一终端，例如，终端102、终端103或终端104。该PUCCH组包括N个载波，N为大于或等于M的整数。应理解，网络设备也可以为终端配置多个PUCCH组，在这种情况下，网络设备可以在每个PUCCH组中获取M个载波。
本申请实施例中，PUCCH可以承载上行控制信息(uplink control information，UCI)，例如，HARQ-ACK信息等。PUCCH可以称为物理上行控制信道、物理上行链路控制信道、上行控制信道等，本申请实施例不对PUCCH的命名形式进行具体限定，在此 作出统一说明，后面不再赘述。
可以理解的，网络设备可以通过多种方式获取具备传输PUCCH能力的M个载波，下面以下述3种方式为例进行介绍。
方式1：M个载波为网络设备激活的。
一种可能的实现方式，网络设备获取具备传输PUCCH能力的M个载波，包括：网络设备将PUCCH组中的全部载波确定为该M个载波。也就是说，M个载波为PUCCH组中的全部载波。在这种情况下，M等于N。网络设备确定了M个载波后，可以向终端发送用于激活该M个载波的指示信息。该指示信息可以包括在无线资源控制(radio resource control，RRC)信令或媒体接入控制控制信元(media access control control element，MAC CE)信令中。
另一种可能的实现方式，网络设备获取具备传输PUCCH能力的M个载波，包括：网络设备在PUCCH组中确定M个载波，M小于N。例如，网络设备根据接入该网络设备的终端数量，接入该网络设备的终端的业务需求或发送PUCCH的终端的业务需求中的至少一项，在PUCCH组中确定M个载波。网络设备确定了M个载波后，可以向终端发送用于激活该M个载波的传输PUCCH能力的指示信息。该指示信息可以包括在MAC CE信令中。
进一步的，在上述两种可能的实施方式中，对于每个PUCCH组，用于激活该M个载波的指示信息和/或用于激活该M个载波的传输PUCCH能力的指示信息可以激活M-1个载波，该M-1个载波不包括PUCCH组内预设的用于传输PUCCH的载波。终端接收到该指示信息后，可以将该M-1个载波，以及PUCCH组内预设的用于传输PUCCH的载波确定为该M个载波。其中，若PUCCH组的数量为1，则该PUCCH组内预设的用于传输PUCCH的载波可以为主小区(primary cell，PCell)对应的载波。若PUCCH组的数量大于1，其中一个PUCCH组为主PUCCH组(primary PUCCH group)，该组内预设的用于传输PUCCH的载波可以为PCell对应的载波。其他PUCCH组为辅PUCCH组(secondary PUCCH group)，该组内预设的用于传输PUCCH的载波可以为PUCCH辅小区(PUCCH secondary cell，PUCCH SCell)对应的载波，也就是说，当PUCCH小区组中包含PCell对应的载波时，该PCell对应的载波用于传输PUCCH；当PUCCH小区中不包含PCell对应的载波即只包含SCell对应的载波时，可以预设一个SCell对应的载波用于传输PUCCH。
方式2：M个载波分别被配置了用于传输PUCCH的配置信息。
其中，用于传输PUCCH的配置信息可以是网络设备配置的。用于传输PUCCH的配置信息可以包括与PUCCH相关的配置，例如，第一集合、PUCCH资源集合等。第一集合可以包括至少一个时间间隔，第一集合还可以称为K 1集合或K 1值的集合等，不予限制。PUCCH资源集合可以包括多个PUCCH时频资源。该时间间隔为传输物理下行共享信道(physical downlink shared channel，PDSCH)与传输第一PUCCH之间的时间间隔。该第一PUCCH可以用于承载PDSCH对应的HARQ-ACK信息，HARQ-ACK信息可以用于指示终端是否正确接收了网络设备下发的PDSCH上承载的下行数据传输块。本申请实施例中，时间间隔的单位可以是符号、子时隙(sub-slot)、时隙(slot)或子帧(sub-frame)等，不予限制。
一种可能的实现方式，网络设备获取具备传输PUCCH能力的M个载波，包括：网络设备将PUCCH组中，被配置了用于传输PUCCH的配置信息的载波，确定为该M个载波。可以理解的，PUCCH组内预设的用于传输PUCCH的载波包括在M个载波中。也就是说，PUCCH组内预设的用于传输PUCCH的载波被配置了用于传输PUCCH的配置信息。
可以理解的，本申请实施例中，被配置了用于传输PUCCH的配置信息的载波可以指该载波有对应的用于传输PUCCH的配置信息。进一步的，M个载波中的载波可以分别被配置用于传输PUCCH的配置信息，M个载波的用于传输PUCCH的配置信息可以完全相同，也可以部分相同，还可以完全不同。M个载波也可以共用用于传输PUCCH的配置信息，也就是说，M个载波的用于传输PUCCH的配置信息相同。
方式3：M个载波中，每个载波在第一PUCCH的时域位置对应的时间单元内包括至少R个非下行符号，R为正整数。
一种可能的实现方式，网络设备确定第一PUCCH的时域位置，根据第一PUCCH是时域位置获取具备传输PUCCH能力的M个载波。进一步的，网络设备根据第一PUCCH的时域位置获取具备传输PUCCH能力的M个载波，包括：网络设备将PUCCH组中，第一PUCCH的时域位置对应的时间单元内包括至少R个非下行符号的载波确定为该M个载波。这样M个载波在第一PUCCH的时域位置对应的时间单元内都包括非下行符号，因此，该M个载波都具备传输PUCCH的能力。
本申请实施例中，时间单元包括至少一个时域符号，例如，正交频分复用(orthogonal frequency division multiplexing，OFDM)符号。示例性的，时间单元可以为时隙、子时隙等。非下行符号可以包括上行符号或灵活符号中的至少一种。
可以理解的，网络设备通过上述方式1或方式2获取到M个载波后，还可以通过方式3在M个载波中确定载波。后续，网络设备可以通过第一指示信息在确定出的M个载波中指示第一载波，终端接收到第一指示信息后，可以根据第一指示信息确定第一载波。
S302：终端获取具备传输PUCCH能力的M个载波。
可以理解的，终端获取的M个载波和网络设备获取的M个载波相同。因此，终端可以采用和网络设备相应的方式获取具备传输PUCCH能力的M个载波，下面进行具体阐述。
对于上述方式1：终端获取具备传输PUCCH能力的M个载波，包括：终端接收来自网络设备的用于激活该M个载波的指示信息或用于激活该M个载波的传输PUCCH能力的指示信息，将用于激活该M个载波的指示信息或用于激活该M个载波的传输PUCCH能力的指示信息指示的M个载波确定为该M个载波。进一步的，若用于激活该M个载波的指示信息或用于激活该M个载波的传输PUCCH能力的指示信息指示了M-1个载波，终端接收到该指示信息后，将该M-1个载波，以及PUCCH组内预设的用于传输PUCCH的载波确定为该M个载波。
对于上述方式2：终端获取具备传输PUCCH能力的M个载波，包括：终端将PUCCH组中，被配置了用于传输PUCCH的配置信息的载波，确定为该M载波。
对于上述方式3：网络设备可以向终端设备发送第二指示信息，该第二指示信息 用于指示第一PUCCH的时域位置。相应地，终端接收到第二指示信息后，根据第二指示信息获取具备传输PUCCH能力的M个载波，即终端执行S302的操作。关于网络设备发送所述第二指示信息的步骤，详见后文中步骤S304的描述。也就是说，在该实施方式中，S304先于S302执行。
一种可能的实现方式，第二指示信息包括第一位置信息和时间间隔信息。其中，第一位置信息用于指示PDSCH的时域位置。时间间隔信息用于指示传输PDSCH与传输第一PUCCH之间的时间间隔。例如，时间间隔信息包括该时间间隔在第一集合中的索引。进一步的，第二指示信息还可以包括第一PUCCH在一个时间单元中的起始位置和第一PUCCH所占的符号数量。
另一种可能的实现方式，第二指示信息包括第一PUCCH在时域上的起始位置和第一PUCCH所占的符号数量。
进一步的，终端根据第二指示信息获取具备传输PUCCH能力的M个载波，包括：终端将PUCCH组中，第二指示信息指示的时域位置对应的时间单元内包括至少R个非下行符号的载波确定为该M个载波。
S303：网络设备向终端发送第一指示信息。
其中，第一指示信息用于指示第一载波，第一载波包括在M个载波中。第一载波为最终用于传输第一PUCCH的载波。
第一指示信息可以有以下两种情况：
情况1：第一指示信息占用的比特数量与M有关联关系。
一种可能的实现方式，第一指示信息占用的比特数量与M有关联关系，包括：第一指示信息占用的比特数量P满足公式：
Figure PCTCN2021072233-appb-000003
进一步的，第一指示信息包括第一载波在M个载波中的索引，这样网络设备即可通过P比特指示M个载波中的任一载波为第一载波。
示例性的，若M为3，则P为2，即第一指示信息占用2比特。若该2比特的取值为“00”，则第一指示信息用于指示M个载波中的第一个载波为第一载波。若该2比特的取值为“01”，则第一指示信息用于指示M个载波中的第二个载波为第一载波。若该2比特的取值为“10”，则第一指示信息用于指示M个载波中的第三个载波为第一载波。
情况2：第一指示信息占用的比特数由网络设备确定。也就是说，网络设备可以配置第一指示信息占用的比特数。在这种情况下，第一指示信息能指示的载波数量Q可以大于M，等于M或小于M。其中，Q可以满足公式：Q＝2 P。
若Q大于M，则第一指示信息可以指示M个载波中的任一载波为第一载波。第一指示信息中，指示了第一载波之外剩余的比特可以用于其他用途，不予限制。
若Q等于M，则第一指示信息可以指示M个载波中的任一载波为第一载波，并且第一指示信息指示了第一载波后，没有剩余的比特。
若Q小于M，在第一指示信息可以指示M个载波中的一部分载波(Q个载波)为第一载波。在这种情况下，网络设备可以在M个载波中，确定至少一个第二载波。第一载波包括在至少一个第二载波中。一种可能的实现方式，至少一个第二载波在第二指示信息指示的时域位置对应的时间单元内包括至少R个非下行符号。
若至少一个第二载波的数量小于或等于Q，则第一指示信息可以指示至少一个第二载波中的任一载波为第一载波。若至少一个第二载波的数量大于Q，则第一指示信息可以指示至少一个第二载波中的Q个载波。一种可能的实现方式，第一指示信息可以指示至少一个第二载波中的前Q个载波，也就是说，第一载波在至少一个第二载波的索引小于或等于Q。其中，至少一个第二载波中的载波可以按照载波标识，从大到小或从小到大排序。
示例性的，若至少一个第二载波包括载波1、载波2和载波3，Q为2，则第一指示信息可以指示载波1或载波2为第一载波。例如，第一指示信息为一个比特位，若取值为“0”，则指示载波1为第一载波，若取值为“1”，则指示载波2为第一载波，反之亦然。
一种可能的实现方式，第一指示信息包括在下行控制信息(downlink control information，DCI)中。
对应的，终端接收来自网络设备的第一指示信息。
进一步的，终端接收到第一指示信息后，可以根据第一指示信息确定第一载波。
示例性的，以上述情况1为例，若M为3，则P为2，即第一指示信息占用2比特。该2比特的取值为“00”的情况下，终端将M个载波中的第一个载波确定的为第一载波。该2比特的取值为“01”的情况下，终端将M个载波中的第二个载波确定的为第一载波。该2比特的取值为“10”的情况下，终端将M个载波中的第三个载波确定的为第一载波。
示例性的，以上述情况2为例，对于Q大于M的情况，若M为2，第一指示信息占用2比特，则该2比特的取值为“00”的情况下，终端将M个载波中的第一个载波确定的为第一载波。该2比特的取值为“01”的情况下，终端将M个载波中的第二个载波确定的为第一载波。第一指示信息中的第一个比特位可以用于其他用途。
示例性的，以上述情况2为例，对于Q等于M的情况，若M为4，第一指示信息占用2比特，则该2比特的取值为“00”的情况下，终端将M个载波中的第一个载波确定的为第一载波。该2比特的取值为“01”的情况下，终端将M个载波中的第二个载波确定的为第一载波。该2比特的取值为“10”的情况下，终端将M个载波中的第三个载波确定的为第一载波。该2比特的取值为“11”的情况下，终端将M个载波中的第四个载波确定的为第一载波。
示例性的，以上述情况2为例，对于Q小于M的情况，终端可以在M个载波中，确定至少一个第二载波。第一载波包括在至少一个第二载波中。一种可能的实现方式，至少一个第二载波在第二指示信息指示的时域位置对应的时间单元内包括至少R个非下行符号。若至少一个第二载波的数量小于或等于Q，则终端可以根据第一指示信息在至少一个第二载波中确定第一载波。若至少一个第二载波的数量大于Q，则终端可以将至少一个第二载波中的载波按照载波标识，从大到小或从小到大排序，根据第一指示信息在至少一个第二载波中确定第一载波，在这种情况下，第一载波在至少一个第二载波的索引小于或等于Q。
S304：网络设备向终端发送第二指示信息。
其中，第二指示信息的描述可以参考上述S302中的介绍，在此不再赘述。
可以理解的，对于第二指示信息包括第一位置信息和时间间隔信息的情况，若终端还未确定第一载波，终端就不知道第一载波被配置的用于传输PUCCH的配置信息，也就是说，终端不知道第一集合包括的时间间隔的数量。在这种情况下，终端没法确定时间间隔信息占用的比特数量，也就没法正确解析第二指示信息，从而得到第一位置信息和时间间隔信息。
为了解决上述问题，可以使得M个载波分别对应的第一集合包括的时间间隔的数量相同；或者，时间间隔信息占用的比特数量由第二集合包括的时间间隔的数量确定，第二集合是M个载波分别对应的第一集合中，包括的时间间隔的数量最多的。这样终端可以正确解析第二指示信息，进而确定第一位置信息和时间间隔信息，根据第一位置信息和时间间隔信息确定第一PUCCH的时域位置。
一种可能的实现方式，第二指示信息可以包括在DCI中。
可以理解的，第一指示信息和第二指示信息可以在一个信息中发送。例如，第一指示信息和第二指示信息都包括在DCI或RRC信令中。也就是说，第一指示信息和第二指示信息可以位于DCI或RRC信令的不同域中。
对应的，终端接收来自网络设备的第二指示信息。
进一步的，终端接收到第二指示信息后，可以根据第二指示信息确定第一PUCCH的时域位置。
示例性的，如图4A所示，为第二指示信息包括第一位置信息和时间间隔信息的情况下第一PUCCH的时域位置的示意图。终端可以将第一位置信息指示的PDSCH的时域位置对应的时间单元索引与时间间隔信息指示的时间间隔相加，得到第一PUCCH所在的时间单元。进一步的，第二指示信息还可以包括第一PUCCH在一个时间单元中的起始位置和第一PUCCH所占的符号数量，终端可以将第一PUCCH所在的时间单元中，起始位置为第一PUCCH在一个时间单元中的起始位置，大小为第一PUCCH所占的符号对应的时域资源，确定为第一PUCCH的时域位置。
示例性的，如图4B所示，为第二指示信息包括第一PUCCH在时域上的起始位置和第一PUCCH所占的符号数量的情况下，第一PUCCH的时域位置的示意图。终端可以将起始位置为第一PUCCH在时域上的起始位置，大小为第一PUCCH所占的符号对应的时域资源，确定为第一PUCCH的时域位置。
S305：终端在第一载波上向网络设备发送第一PUCCH。
其中，第一PUCCH上可以承载PDSCH对应的HARQ-ACK信息等UCI。
一种可能的实现方式，终端通过第一载波，在第二指示信息指示的时域位置上向网络设备发送第一PUCCH。
对应的，网络设备在第一载波上接收来自终端的第一PUCCH。
进一步的，网络设备通过第一载波，在第二指示信息指示的时域位置上接收来自终端的第一PUCCH。
基于图3所示的方法，终端可以获取具备传输PUCCH能力的M个载波，根据第一指示信息在M个载波中确定用于传输第一PUCCH的第一载波，根据第二指示信息确定第一PUCCH的时域位置，并在第一载波上向网络设备发送第一PUCCH。如此，终端可以在PUCCH组中确定能够传输PUCCH的M个载波，进而可以根据网络设备 的指示确定最终用于传输PUCCH的载波。其中，该M个载波可以根据接入网络设备的终端数量，接入该网络设备的终端的业务需求，发送PUCCH的终端的业务需求或载波上是否有非下行符号中的至少一项确定的，因此，该M个载波是PUCCH组中更适合传输PUCCH的载波。另外，M个载波为PUCCH组中的载波的子集，因此，用于指示最终传输PUCCH的载波(即第一载波)的指示信息包括较少的比特，就可以指示M个载波终端任一个载波，既可以减小网络设备和终端的复杂度，又可以减小信令开销。
其中，上述S301-S305中的网络设备或者终端的动作可以由图2所示的通信装置20中的处理器201调用存储器203中存储的应用程序代码来执行，本申请实施例对此不做任何限制。
可选的，在图3所示方法的一种可能的实现方式中，终端可以向网络设备发送第二PUCCH。其中，第二PUCCH用于承载与第一PUCCH对应的PDSCH不同的PDSCH对应的HARQ-ACK信息，但是没有对应的指示信息指示第二PUCCH在哪个载波上传输。在这种情况下，网络设备可以向终端发送用于指示第二PUCCH的时域位置的第三指示信息，以便终端根据第三指示信息确定第二PUCCH的时域位置和用于传输第二PUCCH的载波。具体的，如图5所示，图3所示的方法还可以包括S501-S502。
S501：网络设备向终端发送第三指示信息。
其中，第三指示信息可以用于指示第二PUCCH的时域位置。第三指示信息的介绍可以参数上述对第二指示信息的描述。第三指示信息指示的时域位置和第二指示信息指示的时域位置可以相同也可以不同。
可以理解的，S501可以在S304之前执行，也可以在S304之后执行。
对应的，终端接收来自网络设备的第三指示信息。
可以理解的，终端接收到第三指示信息后，可以根据第三指示信息确定第二PUCCH的时域位置。
S502：终端根据第三指示信息向网络设备发送第二PUCCH。
终端根据第三指示信息向网络设备发送第二PUCCH可以有以下三种情况：
情况3，若第二PUCCH与第一PUCCH位于同一个时间单元，且第三指示信息的发送时刻早于第二指示信息的发送时刻，终端通过第一载波，在第二指示信息指示的时域位置上向网络设备发送第二PUCCH。
对于情况3，本申请实施例先执行S501再执行S304，若第二PUCCH与第一PUCCH位于同一个时间单元，终端根据最新接收到的并且指示的PUCCH的时域位置位于该同一个时间单元的指示信息(本申请实施例中，该指示信息为第二指示信息)，确定第一PUCCH和第二PUCCH的时域位置。也就是说，若第二PUCCH与第一PUCCH位于同一个时间单元，终端在第二指示信息指示的时域位置上向网络设备发送第一PUCCH和第二PUCCH。在这种情况下，终端可以将第二PUCCH和第一PUCCH中承载的信息合并发送。也就是说，终端可以通过第一载波，在第二指示信息指示的时域位置上发送一个PUCCH，该PUCCH上承载的信息包括第二PUCCH和第一PUCCH中承载的信息。
情况4，若第二PUCCH与第一PUCCH位于同一个时间单元，且第三指示信息的 发送时刻晚于第二指示信息的发送时刻，终端通过预设载波，在第三指示信息指示的时域位置上向网络设备发送所述第二PUCCH。
对于情况4，本申请实施例先执行S304再执行S501，若第二PUCCH与第一PUCCH位于同一个时间单元，终端根据最新接收到的并且指示的PUCCH的时域位置位于该同一个时间单元的指示信息(本申请实施例中，该指示信息为第三指示信息)，确定第一PUCCH和第二PUCCH的时域位置。也就是说，若第二PUCCH与第一PUCCH位于同一个时间单元，终端在第三指示信息指示的时域位置上向网络设备发送第一PUCCH和第二PUCCH。在这种情况下，终端可以将第二PUCCH和第一PUCCH中承载的信息合并发送。也就是说，终端可以通过预设载波，在第三指示信息指示的时域位置上发送一个PUCCH，该PUCCH上承载的信息包括第二PUCCH和第一PUCCH中承载的信息。
情况5，若第二PUCCH与第一PUCCH位于不同的时间单元，或者，第二PUCCH所在的时间单元上不传输除第二PUCCH之外的PUCCH，终端通过预设载波，在第三指示信息指示的时域位置上向网络设备发送所述第二PUCCH。
其中，预设载波可以是协议定义的载波，也可以是网络设备确定的载波。预设载波可以是PUCCH组中的任一载波。
对应的，网络设备根据第三指示信息接收来自终端的第二PUCCH。
可以理解的，对于上述情况5，图5所示的方法可以作为一个独立的实施例来实施。换句话说，本申请实施例可以提供一种传输PUCCH的方法，该方法包括S501-S502。
基于图5所示方法，终端可以接收来自网络设备的用于指示第二PUCCH的时域位置的第三指示信息，并根据预设的规则确定用于传输第二PUCCH的载波。这样网络设备可以不需要指示用于传输第二PUCCH的载波，节省了信令开销。
其中，上述S501-S502中的网络设备或者终端的动作可以由图2所示的通信装置20中的处理器201调用存储器203中存储的应用程序代码来执行，本申请实施例对此不做任何限制。
上述图3和图5所示的方法中，网络设备可以通过第一指示信息向终端指示用于传输PUCCH的载波。在具体应用中，网络设备也可以不向终端指示用于传输PUCCH的载波，网络设备和终端可以采用相同的规则确定用于传输PUCCH的载波。具体的，如图6所示，为本申请实施例提供的又一种传输PUCCH的方法，该方法包括：S601-S606。
S601：网络设备获取具备传输PUCCH能力的M个载波。
S602：终端获取具备传输PUCCH能力的M个载波。
其中，S601-S602的具体介绍可以参考上述S301-S302中对应的描述，不予赘述。
S603：网络设备向终端发送第一指示信息。
其中，第一指示信息用于指示PUCCH的时域位置。第一指示信息的介绍可以参考上述图3所示方法中对第二指示信息的介绍。
对应的，终端接收来自网络设备的第一指示信息。
S604：网络设备根据预设规则和第一指示信息确定第一载波。
其中，第一载波包括在M个载波中。第一载波可以用于传输PUCCH。
网络设备根据预设规则和第一指示信息确定第一载波的方式有多种，下面以下述两种方式为例进行介绍。
方式4：网络设备将第一集合中，标识最小的载波确定为第一载波。
其中，第一集合包括的载波在第一指示信息指示的时域位置对应的时间单元内包括至少R个非下行符号，并且第一集合包括的载波在第一指示信息指示的时域位置上包括非下行符号。时间单元与非下行符号的介绍可以参考图3所示方法中所述。
示例性的，以PUCCH组包括载波1-载波4，每个载波上的一个时间单元包括14个符号，第一指示信息指示的时域位置为第2个时间单元中第5个符号至第7个符号，R为3为例，若载波1上的第2个时间单元包括4个非下行符号，分别为第6个符号至第9个符号，则载波1不是第一集合中的载波。若载波2上的第2个时间单元包括2个非下行符号，分别为第5个符号至第6个符号，则载波2不是第一集合中的载波。若载波3上的第2个时间单元包括5个非下行符号，分别为第4个符号至第8个符号，则载波3是第一集合中的载波。若载波4上的第2个时间单元包括3个非下行符号，分别为第5个符号至第7个符号，则载波4是第一集合中的载波。对于第一集合中的载波3和载波4，因为载波3的标识小于载波4，则网络设备可以将载波3确定为第一载波。
方式5：网络设备将第二集合中的载波依次确定为第一载波。也就是说，网络设备将第二集合中的载波按照一定顺序排列，并轮流确定为第一载波。
其中，第二集合包括的载波在第一指示信息指示的时域位置上包括非下行符号。
示例性的，以第二载波集合包括载波1-载波3为例，网络设备在第1个传输PUCCH的时间单元上将载波1确定为第一载波；网络设备在第2个传输PUCCH的时间单元上将载波2确定为第一载波；网络设备在第3个传输PUCCH的时间单元上将载波3确定为第一载波；网络设备在第4个传输PUCCH的时间单元上将载波1确定为第一载波；网络设备在第5个传输PUCCH的时间单元上将载波2确定为第一载波；网络设备在第6个传输PUCCH的时间单元上将载波3确定为第一载波，以此类推。其中，上述多个传输PUCCH的时间单元是以时序确定的，上述第1个传输PUCCH的时间单元即首次或初始传输PUCCH的时间单元。方式6：网络设备根据时间单元与载波的对应关系将第一指示信息指示的时域位置对应的载波确定为第一载波。
其中，时间单元与载波的对应关系可以为预定义的或网络设备配置的。
示例性的，以时间单元与载波的对应关系如表1所示为例，表1中的时间单元1-时间单元5为在时域上连续的时间单元，若第一指示信息指示的时域位置位于时间单元1内，则网络设备确定载波1为第一载波。若第一指示信息指示的时域位置位于时间单元2内，则网络设备确定载波2为第一载波。若第一指示信息指示的时域位置位于时间单元3内，则网络设备确定载波3为第一载波。若第一指示信息指示的时域位置位于时间单元4内，则网络设备确定载波2为第一载波。若第一指示信息指示的时域位置位于时间单元5内，则网络设备确定载波1为第一载波。
表1
时间单元 载波
时间单元1 载波1
时间单元2 载波2
时间单元3 载波3
时间单元4 载波2
时间单元5 载波1
… …
可以理解的，表1所示的时间单元与载波的对应关系仅是示例性的，在具体应用中，时间单元与载波的对应关系还可以是其他形式，不予限制。
S605：终端根据预设规则和第一指示信息确定第一载波。
可以理解的，终端根据预设规则和第一指示信息确定第一载波的过程与网络设备确定第一载波的过程类似，因此可以参考上述S604中对应的描述。
本申请实施例不限制S604和S605的执行顺序，也就是说，本申请实施例可以先执行S604再执行S605，也可以先执行S605再执行S604。
S606：终端在PUCCH的时域位置上，通过第一载波向网络设备发送PUCCH。
其中，PUCCH上可以承载PDSCH对应的HARQ-ACK信息等。HARQ-ACK信息可以用于指示终端是否正确接收了网络设备下发的PDSCH上承载的下行数据传输块。
对应的，网络设备在PUCCH的时域位置上，通过第一载波接收来自终端的PUCCH。
