Description

上行控制信息传输方法及通信装置 技术领域
本申请涉及通信技术领域，尤其涉及一种上行控制信息传输方法及通信装置。
背景技术
在时分双工(time division duplex,TDD)时，对于物理上行控制信道(physical uplink control channel，PUCCH)组中的一个载波来说，如果一个时隙中用于传输物理上行控制信道(physical uplink control channel，PUCCH)的符号全是下行符号，则该时隙上不能传输PUCCH，只能在该时隙之后的时隙中传输PUCCH。因此，该载波上PUCCH承载的上行控制信息(uplink control information，UCI)的传输时延增大。为了降低UCI的传输时延，若该PUCCH组中另一载波上同时隙中的符号是上行符号或灵活符号，则终端设备可以在上述“另一载波”上传输承载所述UCI的PUCCH。
然而，上述“另一载波”上发送UCI的PUCCH资源与该PUCCH组中的其他载波上发送UCI的PUCCH资源在时域上可能重叠，若终端设备同时发送两个或两个以上承载UCI的PUCCH，会影响UCI的传输性能。
发明内容
本申请实施例提供一种上行控制信息传输方法及通信装置，能够提升UCI的传输性能。
第一方面，本申请实施例提供一种上行控制信息传输方法，该方法的执行主体可以是终端设备，也可以是应用于终端设备中的芯片。下面以执行主体是终端设备为例进行描述。该方法包括：终端设备确定第一载波上的第一资源，其中，第一资源用于传输第一上行控制信息UCI，且第一资源与第一载波上的下行资源在时域上重叠。然后，终端设备确定第二载波上的第二资源，第二资源用于传输第一UCI。终端设备确定第二资源与第三资源在时域上重叠，其中，第三资源用于在第三载波上传输第二UCI。终端设备丢弃第二资源上的第一UCI或者丢弃第三资源上的第二UCI。
如此，在终端设备确定第一资源与第一载波上的下行资源在时域上重叠的情况下，终端设备不在第一资源上发送第一UCI，而确定第二资源用于传输第一UCI。在第二资源与第三资源在时域上重叠的情况下，终端设备丢弃一个UCI，如终端设备丢弃第二资源上的第一UCI，或丢弃第三资源上的第二UCI，以使得终端设备无需同时发送第一UCI和第二UCI。由于终端设备的功率一定，在终端设备丢弃一个UCI的情况下，终端设备在某一个时刻的功率用于发送一个UCI，而非在同一时刻发送两个或两个以上的UCI，从而提升UCI的传输性能。
在一种可能的设计中，终端设备丢弃第二资源上的第一UCI，包括：当第一UCI满足预设条件，终端设备丢弃第二资源上的第一UCI。其中，预设条件包括以下至少一项：第一UCI的优先级低于第二UCI的优先级；传输第一UCI的第二资源晚于第三资源。
在第一项预设条件被实现的情况下，终端设备丢弃低优先级的第一UCI，以使得优先级较高的第二UCI能够发送到网络设备。在第二项预设条件被实现的情况下，使得时间上 较近的第二UCI能够发送到网络设备。

在一种可能的设计中，本申请实施例上行控制信息传输方法还包括：终端设备接收来自网络设备的第一指示信息。其中，第一指示信息指示终端设备丢弃第二资源上的第一UCI或者丢弃第三资源上的第二UCI。

在一种可能的设计中，当终端设备丢弃第三资源上的第二UCI，本申请实施例上行控制信息传输方法还包括：终端设备确定在第三载波的PUSCH资源上传输第二UCI。其中，第三载波的PUSCH资源与第三资源在时域上重叠。

第二方面，本申请实施例提供一种上行控制信息传输方法，该方法的执行主体可以是网络设备，也可以是应用于网络设备中的芯片。下面以执行主体是网络设备为例进行描述。该方法包括：网络设备确定第一载波上的第一资源，其中，第一资源用于传输第一上行控制信息UCI，且第一资源与第一载波上的下行资源在时域上重叠。然后，网络设备确定第二载波上的第二资源，第二资源用于传输第一UCI。网络设备确定第二资源与第三资源在时域上重叠，其中，第三资源用于在第三载波上传输第二UCI。网络设备确定第二资源上的第一UCI被丢弃或者第三资源上的第二UCI被丢弃。
在一种可能的设计中，网络设备确定第二资源上的第一UCI被丢弃，包括：当第一UCI满足预设条件，网络设备第二资源上的第一UCI被丢弃，其中，预设条件包括以下至少一项：第一UCI的优先级低于第二UCI的优先级；传输第一UCI的第二资源晚于第三资源。
在一种可能的设计中，第一UCI包括调度请求SR和信道状态信息CSI中的至少一项，第二UCI包括混合自动重传请求确认HARQ-ACK信息；或者，第一UCI包括CSI，第二UCI包括SR；或者，第一UCI包括第一优先级的CSI，第二UCI包括第二优先级的CSI，第一优先级低于第二优先级；或者，第一UCI包括第一优先级的SR，第二UCI包括第二优先级的SR；或者，第一UCI包括第一优先级的HARQ-ACK信息，第二UCI包括第二优先级的HARQ-ACK信息。
在一种可能的设计中，网络设备确定第三资源上的第二UCI被丢弃，包括：当第二UCI满足预设条件，网络设备确定第三资源上的第二UCI被丢弃，其中，预设条件包括以下至少一项：第二UCI的优先级低于第一UCI的优先级；传输第二UCI的第三资源晚于第二资源。

在一种可能的设计中，本申请实施例上行控制信息传输方法还包括：网络设备向终端设备发送第一指示信息。其中，第一指示信息指示终端设备丢弃第二资源上的第一UCI或者丢弃第三资源上的第二UCI。
在一种可能的设计中，当网络设备确定第二资源上的第一UCI被丢弃，本申请实施例上行控制信息传输方法还包括：网络设备确定在第三载波的目标资源上接收来自终端设备的第一UCI。其中，第三载波的目标资源是根据第二资源确定的。
在一种可能的设计中，当网络设备确定第三资源上的第二UCI被丢弃，本申请实施例上行控制信息传输方法还包括：网络设备确定在第二载波的目标资源上接收来自终端设备的第二UCI。其中，第二载波的目标资源是根据第三资源确定的。
在一种可能的设计中，本申请实施例上行控制信息传输方法还包括：网络设备向终端设备发送第二指示信息。其中，第二指示信息指示终端设备在同一载波上发送第一UCI和第二UCI。

在一种可能的设计中，当网络设备确定第三资源上的第二UCI被丢弃，本申请实施例上行控制信息传输方法还包括：网络设备确定在第三载波的PUSCH资源上接收来自终端设备的第二UCI。其中，第三载波的PUSCH资源与第三资源在时域上重叠。
在一种可能的设计中，第三载波与第一载波为同一载波，或者，第三载波与第二载波为同一载波。
第三方面，本申请实施例提供一种上行控制信息传输方法，该方法的执行主体可以是终端设备，也可以是应用于终端设备中的芯片。下面以执行主体是终端设备为例进行描述。该方法包括：终端设备确定第一载波上的第一资源，其中，第一资源用于传输第一上行控制信息UCI，且第一资源与第一载波上的下行资源在时域上重叠。然后，终端设备确定第二载波上的第二资源，其中，第二资源用于传输第一UCI，第二资源满足预设条件，预设条件包括：第二资源与第三资源在时域上不重叠，第三资源是第三载波上用于传输第二UCI的资源。终端设备在第二资源上向网络设备发送第一UCI，以及在第三资源上向网络设备发送第二UCI。
如此，在终端设备确定第一资源与第一载波上的下行资源在时域上重叠的情况下，终端设备不在第一资源上发送第一UCI，而确定第二资源用于传输第一UCI。由于第二资源是满足预设条件的资源，即第二资源与第三资源在时域上不重叠。也就是说，由于第二资源是满足预设条件的资源，所以，终端设备重新确定的第二资源与其他载波上传输UCI的资源(如第三资源)在时域上不重叠。此种情况下，终端设备不存在同时发送第一UCI和第二UCI的情况。由于终端设备的功率是固定的，在终端设备确 定的第二资源与第三资源不重叠的情况下，终端设备在某一个时刻的功率用于发送一个UCI，而非在同一时刻发送两个或两个以上的UCI，从而提升UCI的传输性能。
在一种可能的设计中，本申请实施例上行控制信息传输方法还包括：终端设备接收来自网络设备的下行控制信息DCI，DCI指示物理上行控制信道PUCCH的时域资源，且时域资源与第三资源在时域上不重叠。终端设备确定第二载波上的第二资源，包括：终端设备根据DCI指示的时域资源，确定第二资源。
也就是说，网络设备根据预设条件，在RRC信令指示的PUCCH资源中进行资源选择，以筛选出满足预设条件的时域资源。如此，DCI指示的PUCCH的时域资源与其他载波上发送UCI的PUCCH资源在时域上不重叠。由于终端设备是基于DCI指示的PUCCH的时域资源确定的第二资源，从而避免“PUCCH载波切换”之后与其他载波上的PUCCH资源在时域上重叠的现象，终端设备在某一时刻的功率发送一个UCI即可，从而提升了UCI的传输性能。
在一种可能的设计中，本申请实施例上行控制信息传输方法还包括：终端设备接收来自网络设备的无线资源控制RRC信令。其中，RRC信令指示物理上行控制信道PUCCH资源。终端设备确定第二载波上的第二资源，包括：终端设备确定PUCCH资源中满足预设条件的资源为第二资源。
也就是说，终端设备根据预设条件，在RRC信令指示的PUCCH资源中进行资源选择，以筛选出满足预设条件的资源，作为第二资源，从而避免“PUCCH载波切换”之后与其他载波上的PUCCH资源在时域上重叠的现象，终端设备在某一时刻的功率发送一个UCI即可，从而提升了UCI的传输性能。
在一种可能的设计中，第二资源与第三资源在时域上间隔至少N个时域资源单元，其中，N为正整数，以使终端设备能够及时地从第二载波切换至第三载波，提高了第二UCI发送成功的可能性，从而提升了UCI的传输性能。
在一种可能的设计中，时域资源单元是基于第二资源的子载波间隔和第三资源的子载波间隔中较小的子载波间隔确定的。由于子载波间隔越小，一个时域资源单元，例如符号或时隙对应的时间长度越大，以为终端设备切换载波提供充足的时间。
第四方面，本申请实施例提供一种上行控制信息传输方法，该方法的执行主体可以是网络设备，也可以是应用于网络设备中的芯片。下面以执行主体是网络设备为例进行描述。该方法包括：网络设备确定第一载波上的第一资源，其中，第一资源用于传输第一上行控制信息UCI，且第一资源与第一载波上的下行资源在时域上重叠。然后，网络设备确定第二载波上的第二资源，其中，第二资源用于传输第一UCI，第二资源满足预设条件，预设条件包括：第二资源与第三资源在时域上不重叠，第三资源是第三载波上用于传输第二UCI的资源。网络设备在第二资源上接收来自终端设备的第一UCI，以及在第三资源上接收来自终端设备的第二UCI。
在一种可能的设计中，本申请实施例上行控制信息传输方法还包括：网络设备向终端设备发送下行控制信息DCI。其中，DCI指示物理上行控制信道PUCCH的时域资源，且时域资源与第三资源在时域上不重叠，DCI用于终端设备确定第二资源。
在一种可能的设计中，本申请实施例上行控制信息传输方法还包括：网络设备向终端设备发送无线资源控制RRC信令。其中，RRC信令指示物理上行控制信道PUCCH资源， RRC信令用于终端设备确定第二资源。
在一种可能的设计中，第二资源与第三资源在时域上间隔至少N个时域资源单元，其中，N为正整数。
在一种可能的设计中，时域资源单元是基于第二资源的子载波间隔和第三资源的子载波间隔中较小的子载波间隔确定的。
第五方面，本申请实施例提供一种上行控制信息传输方法，该方法的执行主体可以是终端设备，也可以是应用于终端设备中的芯片。下面以执行主体是终端设备为例进行描述。该方法包括：终端设备确定第一资源与第二资源之间的时间间隔，第一资源用于在第一载波上传输第一上行控制信息UCI，第二资源用于在第二载波上传输第二UCI。当时间间隔小于第一预设值，终端设备丢弃第一资源上的第一UCI或者丢弃第二资源上的第二UCI。
如此，终端设备根据第一资源和第二资源之间的时间间隔来确定是否丢弃一个UCI。例如，在时间间隔小于第一预设值的情况下，终端设备无法及时在第一载波和第二载波之间切换，此种情况下，终端设备丢弃某一个载波上的UCI，从而使得终端设备无需在第一载波和第二载波之间切换，也就不存在“终端设备无法及时切换至某一载波发送UCI”的问题。
在一种可能的设计中，终端设备确定第一资源与第二资源之间的时间间隔之前，本申请实施例上行控制信息传输方法还包括：终端设备确定第三载波上的第三资源。其中，第三资源用于传输第一UCI或者第二UCI，且第三资源与第三载波上的下行资源在时域上重叠。也就是说，第一UCI可以是经过“PUCCH载波切换”处理，确定在第一载波上发送的信息。第二UCI可以是经过“PUCCH载波切换”处理，确定在第二载波上发送的信息。
在一种可能的设计中，本申请实施例上行控制信息传输方法还包括：终端设备向网络设备发送第一预设值，以使网络设备确定哪一UCI被丢弃。
第六方面，本申请实施例提供一种上行控制信息传输方法，该方法的执行主体可以是网络设备，也可以是应用于网络设备中的芯片。下面以执行主体是网络设备为例进行描述。该方法包括：网络设备确定第一资源与第二资源之间的时间间隔。其中，第一资源用于在第一载波上传输第一上行控制信息UCI，第二资源用于在第二载波上传输第二UCI。当时间间隔小于第一预设值，网络设备确定第一资源上的第一UCI被丢弃或者第二资源上的第二UCI被丢弃。
在一种可能的设计中，网络设备确定第一资源与第二资源之间的时间间隔之前，本申请实施例上行控制信息传输方法还包括：网络设备确定第三载波上的第三资源。其中，第三资源用于传输第一UCI或第二UCI，且第三资源与第三载波上的下行资源在时域上重叠。
在一种可能的设计中，本申请实施例上行控制信息传输方法还包括：网络设备接收来自终端设备的第一预设值。
第七方面，本申请实施例提供一种上行控制信息传输方法，该方法的执行主体可以是终端设备，也可以是应用于终端设备中的芯片。下面以执行主体是终端设备为例进行描述。该方法包括：终端设备确定预设时域资源单元内物理上行控制信道PUCCH的发送次数， 其中，PUCCH包括承载第一上行控制信息UCI的PUCCH和承载第二UCI的PUCCH，第一UCI是在第一载波的第一资源上传输的信息，第二UCI是在第二载波的第二资源上传输的信息。然后，终端设备根据发送次数和第二预设值确定丢弃第一资源上的第一UCI，或者终端设备根据发送次数和第二预设值，确定丢弃第二资源上的第二UCI。
如此，终端设备根据预设时域资源单元内PUCCH的发送次数和第二预设值，确定是否丢弃某一个资源上的UCI，以避免由于终端设备自身能力的限制，导致终端设备无法及时在第一载波和第二载波之间切换。当终端设备丢弃某一个载波上的UCI，终端设备无需在第一载波和第二载波之间切换，也就不存在“终端设备无法及时切换至某一载波发送UCI”的问题。
在一种可能的设计中，终端设备确定预设时域资源单元内PUCCH的发送次数之前，本申请实施例上行控制信息传输方法还包括：终端设备确定第三载波上的第三资源，第三资源用于传输第一UCI或者第二UCI，且第三资源与第三载波上的下行资源在时域上重叠。也就是说，第一UCI可以是经过“PUCCH载波切换”处理，确定在第一载波上发送的信息。第二UCI可以是经过“PUCCH载波切换”处理，确定在第二载波上发送的信息。
第八方面，本申请实施例提供一种上行控制信息传输方法，该方法的执行主体可以是网络设备，也可以是应用于网络设备中的芯片。下面以执行主体是网络设备为例进行描述。该方法包括：网络设备确定预设时域资源单元内物理上行控制信道PUCCH的接收次数，其中，PUCCH包括承载第一上行控制信息UCI的PUCCH和承载第二UCI的PUCCH，第一UCI是在第一载波的第一资源上传输的信息，第二UCI是在第二载波的第二资源上传输的信息。然后，网络设备根据接收次数和第二预设值确定第一资源上的第一UCI被丢弃，或者网络设备根据接收次数和第二预设值，确定第二资源上的第二UCI被丢弃。
在一种可能的设计中，网络设备确定预设时域资源单元内物理上行控制信道PUCCH的接收次数之前，本申请实施例上行控制信息传输方法还包括：网络设备确定第三载波上的第三资源。其中，第三资源用于传输第一UCI或者第二UCI，且第三资源与第三载波上的下行资源在时域上重叠。

具体实施方式
本申请的说明书以及附图中的术语“第一”和“第二”等是用于区别不同的对象，或者用于区别对同一对象的不同处理，而不是用于描述对象的特定顺序。此外，本申请的描述中所提到的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括其他没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。需要说明的是，本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
首先，介绍本申请实施例所涉及的技术术语：
1、物理上行控制信道(physical uplink control channel，PUCCH)
PUCCH用于承载上行控制信息(uplink control information，UCI)。UCI类型包括以下至少一项：混合自动重传请求确认(hybrid automatic repeat request acknowledgment，HARQ-ACK)信息、调度请求(scheduling request，SR)信息和信道状态信息(channel state information，CSI)。其中，HARQ-ACK信息用于向网络设备反馈物理下行共享信道(physical downlink shared channel，PDSCH)是否正确解码。SR信息用于向网络设备请求上行资源， 以便在物理上行共享信道(physical uplink shared channel，PUSCH)上传输上行数据。CSI用于向网络设备反馈下行信道质量，网络设备根据反馈的CSI选择信道质量较好的下行信道进行下行数据调度。
PUCCH的格式(format)有5种格式，包括PUCCH格式0～4，如表1所示。PUCCH格式0的长度是1个或2个正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，在频域上占用1个物理资源模块(physical resource block，PRB)，传输UCI的比特(bit)数小于或者等于2。PUCCH格式1的长度是4～14个符号，在频域上占用1个PRB，传输UCI的比特数小于或者等于2。PUCCH格式2的长度是1个或2个符号，在频域上最多占用16个PRB，传输UCI的比特数大于2。PUCCH格式3的长度是4～14个符号，在频域上占用1个或多个PRB，传输UCI的比特数大于2。其中，PUCCH格式3在频域上占用的PRB个数是可以是2、3、或5的倍数。PUCCH格式4的长度是4～14个符号，在频域上占用1个PRB，传输UCI的比特数大于2。
表1
Figure PCTCN2021072303-appb-000001
PUCCH格式0和PUCCH格式2的符号个数为1个或2个，称为短PUCCH。PUCCH格式1、PUCCH格式3和PUCCH格式4的符号个数为{4-14}，称为长PUCCH。
2、PUCCH组(PUCCH group)与“载波切换”
一个PUCCH组包括至少一个载波(carrier)。并且，一个PUCCH组中只能有一个载波用于传输PUCCH。其中，传输PUCCH的载波可以是主载波，也可以是辅载波。PUCCH组至多有2个，称为主PUCCH组(primary PUCCH group)和辅PUCCH组(secondary PUCCH group)。上述“载波”也可以描述为“分量载波(component carrier)”、“小区(cell)”。“载波”和“小区”可以替换，一个载波对应一个小区，一个小区可以配置一个载波，也可以配置多个载波。
载波切换，是指某一载波例如载波A上传输UCI的情况下，若该载波上传输该UCI的PUCCH资源与该载波上的下行资源在时域上重叠，则在另一载波例如载波B上传输承载上述UCI的PUCCH。这两个载波，即载波A和载波B，可以是同一个PUCCH组中的两个载波，也可以是不同PUCCH组中的载波。其中，载波切换过程在一个时域资源单元内完成，也可以理解为PUCCH从一个载波切到另外一个载波时，PUCCH的时域资源在一个时域资源单元内，不能跨时域资源单元的边界。时域资源单元可以是以下至少一项：时隙、或子时隙、或子帧、或无线帧。也就是说，UCI从一个载波切到另一载波时，不能跨时隙或者子时隙。“载波切换”也可以描述为“PUCCH载波切换”、或者“UCI载波切换”。示例性的，“载波切换”过程的介绍如下：
在主PUCCH组中，当主载波上的PUCCH承载HARQ-ACK信息时，该PUCCH组中 其它载波上PDSCH对应的HARQ-ACK信息也在该主载波上反馈。其中，K1指示PDSCH和HARQ-ACK信息反馈之间的时延。示例性的，参见图1，终端设备在时隙0上通过PDSCH接收下行数据。终端设备确定“K1＝3”，即在PDSCH所在时隙(如图1中的时隙0)之后的第三个时隙(如图1中的时隙3)反馈HARQ-ACK信息。“主载波上PDSCH对应的HARQ-ACK信息”和“辅载波1上PDSCH对应的HARQ-ACK信息”通过主载波上的PUCCH传输，如图1中的曲线箭头所示。在图1中，“D”表示一个或多个下行符号，“U”表示一个或多个上行符号，“F”表示一个或多个灵活符号(flexible symbol)。
从图1可以看出，由于主载波上时隙0和时隙1中的符号全是下行符号，不能用于PUCCH传输。因此，HARQ-ACK信息的传输时延增大。
为了降低HARQ-ACK信息的传输时延，可以在PUCCH组中除主载波之外的一个载波上反馈HARQ-ACK信息。示例性的，参见图2，由于辅载波1上时隙1中的符号全是上行符号，可以用于PUCCH传输。因此，HARQ-ACK信息可以在辅载波1的时隙1上反馈。其中，反馈HARQ-ACK信息的载波，可以通过下行控制信息(downlink control information，DCI)动态指示，也可以半静态配置，还可以通过预设规则确定。示例性的，预设规则可以例如但不限于：按照载波的索引(index)从小到大的顺序，确定反馈HARQ-ACK信息的载波。
终端设备确定在辅载波1上反馈HARQ-ACK信息之后，可能存在如下情况：“辅载波1上承载HARQ-ACK信息的PUCCH资源”与“PUCCH组中除上述辅载波1之外的载波上的PUCCH资源”在时域上重叠。也就是说，存在“不同载波上的PUCCH资源在时域上重叠”的情况。需要说明的是，本申请中所述的“在时域上重叠”包括“在时域上部分重叠”或者“在时域上全部重叠”。例如，A与B“重叠”是指：A和B在时域上占据的资源有相同的部分。例如，A和B在时域上占据的资源完全相同，或A在时域上占据的一部分资源和B在时域上占据的全部资源相同，即A包括B，或B在时域上占据的一部分资源和A在时域上占据的全部资源相同，即B包括A，或A在时域上占据的一部分资源和B在时域上占据的一部分资源相同。
下面，通过三个示例进行介绍：
情况一、
参见图3a，“主载波的子载波间隔”与“辅载波1的子载波间隔”相同。“主载波上承载HARQ-ACK信息的PUCCH资源”与“主载波上承载CSI的PUCCH资源”在时域上未重叠，但是，“主载波上承载HARQ-ACK信息的PUCCH资源”与“主载波上的下行符号”在时域上重叠，如图3a中主载波上的“符号索引1至符号索引8”所示。此种情况下，终端设备在辅载波1上重新选择一个PUCCH资源(如图3a中辅载波1上的“符号索引7至符号索引11”所示)，以发送上述HARQ-ACK信息。但是，“辅载波1上重新选择的PUCCH资源”与“主载波上承载CSI的PUCCH资源”在时域上重叠，如图3a所示，“辅载波1上重新选择的PUCCH资源”与“主载波上承载CSI的PUCCH资源”在符号索引11对应的符号上重叠。
情况二、
参见图3b，“主载波的子载波间隔”与“辅载波1的子载波间隔”相同。“主载波上承载HARQ-ACK信息的PUCCH资源”与“主载波上的下行符号”在时域上重叠，如图3b中主载波上的“符号索引4至符号索引10”所示。“主载波上承载HARQ-ACK信息的PUCCH资源” 还与“主载波上承载CSI的PUCCH资源”在时域上重叠，如图3b中“主载波上承载HARQ-ACK信息的PUCCH资源”与“主载波上承载CSI的PUCCH资源”在符号索引11对应的符号上重叠。此种情况下，终端设备在辅载波1上确定PUCCH资源(如图3b中辅载波1对应的“符号索引4至符号索引11”所示)，以发送上述HARQ-ACK信息。但是，“辅载波1上的PUCCH资源”与“主载波上承载CSI的PUCCH资源”在时域上重叠，如“辅载波1上的PUCCH资源”与“主载波上承载CSI的PUCCH资源”在符号索引11对应的符号上重叠。
情况三、
参见图3c，“主载波的子载波间隔”与“辅载波1的子载波间隔”不同。“主载波上承载HARQ-ACK信息的PUCCH资源”与“主载波上承载CSI的PUCCH资源”在时域上未重叠，但是，“主载波上承载HARQ-ACK信息的PUCCH资源”与“主载波上的下行符号”在时域上重叠。此种情况下，终端设备在辅载波1上确定PUCCH资源(如图3c中辅载波1对应的“符号索引1至符号索引11”所示)，以发送上述HARQ-ACK信息。在图3c中，主载波的子载波间隔为30kHz，辅载波的子载波间隔为15kHz。“辅载波1上的PUCCH资源”与“主载波上承载CSI的PUCCH资源”在时域上重叠。
综上，不同载波上的PUCCH资源在时域上重叠的情况下，终端设备同时发送两个或两个以上的UCI，UCI的传输性能受到影响。
本申请实施例提供一种上行控制信息传输方法，本申请实施例上行控制信息传输方法适用于各种通信系统。本申请实施例提供的上行控制信息传输方法可以应用于长期演进(long term evolution，LTE)系统，或者第五代(fifth-generation，5G)通信网络，或者其他类似的网络中，或者未来的其它网络中。图4为可适用于本申请实施例上行控制信息传输方法的通信系统的架构示意图，该通信系统可以包括终端设备40和网络设备41。其中，终端设备40与网络设备41之间无线连接。其中，终端设备40的数量可以为一个或多个，网络设备41也可以为一个或多个。图4中仅示出了一个网络设备41和两个终端设备40。图4仅为示意图，并不构成对本申请实施例通信方法的适用场景的限定。
终端设备40，又称为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等，是一种向用户提供语音/数据连通性的设备，例如，具有无线连接功能的手持式设备或车载设备等。终端设备具体可以为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备、虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、或智慧家庭(smart home)中的无线终端，5G通信网络或5G之后的通信网络中的终端设备等，本申请实施例对此不作限定。
网络设备41是无线通信网络中的设备，例如将终端设备40接入到无线通信网络的无线接入网(radio access network，RAN)节点。目前，一些RAN节点的举例为：gNB、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node  B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)，或5G通信网络或5G之后的通信网络中的网络侧设备等。
本申请实施例描述的通信系统以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定。本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面对本申请实施例提供的上行控制信息传输方法进行具体阐述。
需要说明的是，本申请下述实施例中各个网元之间的消息名字或消息中各参数的名字等只是一个示例，具体实现中也可以是其他的名字，在本申请实施例中，涉及到的资源，如第一资源、第二资源、第三资源、第四资源、第五资源、第六资源、第七资源、第八资源、复用资源1、复用资源2、目标资源1、目标资源2等，包括时域资源与频域资源(或者简称为时频资源)，且，在频域上可以包括至少一个资源块(resource block，RB)。在此统一说明，以下不再赘述。
本申请实施例提供了一种上行控制信息传输方法，该上行控制信息传输方法应用在上行控制信息的传输过程中。参见图5，该上行控制信息传输方法包括如下步骤：
S501、第一终端设备确定第一载波上的第一资源。
其中，第一载波可以是主载波，也可以是辅载波。
其中，“第一资源”的介绍包括如下两个方面：
第一方面，第一资源用于传输第一UCI。其中，第一UCI包括的信息可以例如但不限于如下至少一项：HARQ-ACK信息、SR信息和CSI。第一UCI通过PUCCH传输，PUCCH的格式可以是PUCCH格式0～4中的一种格式。
其中，第一资源的配置过程如图6a所示：
S501a、网络设备向第一终端设备发送配置信息。相应的，第一终端设备接收来自网络设备的配置信息。
其中，配置信息指示PUCCH资源。配置信息指示以下信息中的至少一项：一个或多个PUCCH资源集合、每个PUCCH资源集合中的PUCCH资源、或每个PUCCH资源集合中的PUCCH可以包括UCI的最大比特数。其中，每个PUCCH资源集合中的PUCCH资源可以是：PUCCH的起始符号位置、PUCCH的符号个数、或PUCCH的频域位置等。
S501b、网络设备向第一终端设备发送DCI。相应的，第一终端设备接收来自网络设备的DCI。
其中，DCI指示PDSCH资源和第一资源。第一资源属于配置信息指示的资源。
需要说明的是，S501b是可选的步骤。网络设备可以通过DCI动态地调度第一资源。网络设备也可以通过无线资源控制(radio resource control，RRC)信令配置半静态调度(semi-persistent scheduling，SPS)的第一资源。例如，第一终端设备接收DCI之后，第一终端设备确定是半静态调度方式。此种情况下，第一终端设备保存上述DCI的信息，每隔固定的周期在相同的PDSCH资源位置上接收PDSCH传输的数据，以及在相同的第一资 源位置上反馈HARQ-ACK信息。此种情况下，PDSCH是高层信令，如RRC信令配置的半静态调度的PDSCH。PUCCH则由高层信令配置，且用于反馈半静态PDSCH的HARQ-ACK信息。
需要说明的是，当第一UCI承载CSI或者SR时，第一资源也是RRC信令配置的。在第一UCI承载HARQ-ACK信息的情况下，本申请实施例上行信息控制方法还可以包括S501c：
S501c、网络设备通过PDSCH资源向第一终端设备发送下行数据。相应的，第一终端设备通过PDSCH资源接收来自网络设备的下行数据。
其中，PDSCH资源是S501b中DCI指示的资源，也可以是半静态调度的PDSCH资源。
需要说明的是，S501c是可选的步骤。网络设备也可以不执行S501c，即PDSCH资源上未传输数据。此种情况下，第一终端设备通过PDSCH资源未能够接收到来自网络设备的下行数据，该PDSCH对应的HARQ-ACK信息为否定应答(negative acknowledgement，NACK)。
第二方面，第一资源与第一载波上的下行资源在时域上重叠。其中，下行资源可以为下行符号占据的资源，下行资源也可以为下行信号占据的资源。例如，下行信号可以是下行同步信号块(synchronization signal block，SSB)。一个SSB包括同步信号(synchronization signal，SS)和物理广播信道(physical broadcast channel，PBCH)。
示例性的，以第一资源是反馈HARQ-ACK信息的PUCCH资源为例，第一资源与下行符号在时域上重叠，具体可以参见图3a、图3b、或图3c的介绍，此处不再赘述。
S502、第一终端设备确定第二载波上的第二资源。
其中，第二资源用于传输第一UCI。
其中，第二载波是与第一载波不同的一个载波。例如，在一个PUCCH组中，第一载波是主载波的情况下，第二载波可以是一个辅载波。第一载波是一个辅载波的情况下，第二载波可以是主载波，或第二载波可以是另一个辅载波。也就是说，第一UCI是经过第一终端设备“载波切换”处理之后，从第一载波切换至第二载波上传输的信息。其中，“载波切换”的过程可以参见S501和S502的介绍。
示例性的，在图3a中，第一UCI包括HARQ-ACK信息。第一载波为主载波，第二载波为辅载波1。第二资源为辅载波1上符号索引7至符号索引11对应的资源。在图3b中，第一UCI包括HARQ-ACK信息。第一载波为主载波，第二载波为辅载波1。第二资源为辅载波1上符号索引4至符号索引11对应的资源。在图3c中，第一UCI包括HARQ-ACK信息。第一载波为主载波，第二载波为辅载波1。第二资源为辅载波1上符号索引1至符号索引11对应的资源。
S503、第一终端设备确定第二资源与第三资源在时域上重叠。
其中，第三资源用于在第三载波上传输第二UCI。
其中，第三载波与第一载波可以是同一载波，如图3a、图3b或图3c所示。
或者，第三载波与第二载波可以为同一载波，如图9所示，第一载波为主载波，第二载波和第三载波为辅载波1。第一UCI包括HARQ-ACK信息，第一UCI是从主载波(即第一载波)切换至辅载波1(即第二载波)之后，在辅载波1上传输的信息。第二资源为辅载波1上符号索引4至符号索引11对应的资源。第二UCI包括CSI，第三资源为辅载 波1上符号索引11至符号索引13对应的资源，如图9中未加横线的“CSI”所在方框对应的资源。第二资源与第三资源在符号索引11对应的资源上重叠。
或者，第三载波是除第一载波和第二载波之外的其他载波。
其中，第二UCI包括的信息可以例如但不限于如下至少一项：HARQ-ACK信息、SR信息和CSI。第一UCI中的信息类型和第二UCI中的信息类型可以相同，也可以不同，本申请实施例对此不作限定。第二UCI通过PUCCH传输，PUCCH的格式可以是PUCCH格式0～4中的一种格式。第二UCI可以是未经过第一终端设备“载波切换”处理的信息，也可以是经过第一终端设备“载波切换”处理之后，从第四载波切换至第三载波上传输的信息。例如，第四载波上的第四资源用于传输第二UCI，且第四资源与第四载波上的下行资源在时域上重叠。如此，第一终端设备无法在第四资源上发送第二UCI。第一终端设备在第三载波上确定上述第三资源。
示例性的，以第三载波与第一载波为同一载波为例，在图3a中，第一UCI包括HARQ-ACK信息，第二载波是辅载波1，第二资源是辅载波1上符号索引7至符号索引11对应的资源。第二UCI包括CSI，第三载波是主载波，第三资源是主载波上符号索引11至符号索引13对应的资源。第二资源与第三资源在符号索引11对应的符号上重叠。在图3b中，第一UCI包括HARQ-ACK信息，第二载波是辅载波1，第二资源是辅载波1上符号索引4至符号索引11对应的资源。第二UCI包括CSI，第三载波是主载波，第三资源是主载波上符号索引11至符号索引13对应的资源。第二资源与第三资源在符号索引11对应的符号上重叠。在图3c中，第一UCI包括HARQ-ACK信息，第二载波是辅载波1，第二资源是辅载波1上时隙0中符号索引1至符号索引11对应的资源。第二UCI包括CSI，第三载波是主载波，第三资源是主载波上时隙1中符号索引2至符号索引6对应的资源。由于主载波的子载波间隔为30kHz，辅载波1的子载波间隔为15kHz，辅载波1上一个符号的长度是主载波上一个符号的长度的两倍。第二资源与第三资源在时域上重叠。
S504、第一终端设备丢弃第二资源上的第一UCI或者丢弃第三资源上的第二UCI。相应的，网络设备确定第二资源上的第一UCI被丢弃或者第三资源上的第二UCI被丢弃。
也就是说，对于第一终端设备而言，第一终端设备执行S504a：
S504a、第一终端设备丢弃第二资源上的第一UCI或者丢弃第三资源上的第二UCI。
对于网络设备而言，网络设备执行S504b：
S504b、网络设备确定第二资源上的第一UCI被丢弃或者第三资源上的第二UCI被丢弃。其中，网络设备同样执行S501至S503。
具体地，S504可以有如下几种实现方式：
实现方式1，第一终端设备丢弃第二资源上的第一UCI，且第一终端设备在第三资源上向网络设备发送第二UCI。相应的，网络设备确定第二资源上的第一UCI被丢弃，网络设备在第三资源上接收来自第一终端设备的第二UCI，如图5中的“情况1”虚线框所示。
或者，第一终端设备在第二资源上向网络设备发送第一UCI，且丢弃第三资源上的第二UCI。相应的，网络设备在第二资源上接收来自第一终端设备的第一UCI，且确定第三资源上的第二UCI被丢弃，如图5中的“情况2”虚线框所示。
实现方式2，第一终端设备在第二资源上向网络设备不发送第一UCI，且第一终端设备在第三资源上向网络设备发送第二UCI。相应的，网络设备在第二资源上不接收来自第 一终端设备的第一UCI，且网络设备在第三资源上接收来自第一终端设备的第二UCI。
或者，第一终端设备在第二资源上向网络设备发送第一UCI，且第一终端设备在第三资源上向网络设备不发送第二UCI。相应的，网络设备在第二资源上接收来自第一终端设备的第一UCI，且网络设备在第三资源上不接收来自第一终端设备的第二UCI。
实现方式3，第一终端设备在第二资源上向网络设备不发送承载第一UCI的PUCCH，且第一终端设备在第三资源上向网络设备发送承载第二UCI的PUCCH。相应的，网络设备在第二资源上不接收来自第一终端设备的承载第一UCI的PUCCH，且网络设备在第三资源上接收来自第一终端设备的承载第二UCI的PUCCH。
或者，第一终端设备在第二资源上向网络设备发送承载第一UCI的PUCCH，且第一终端设备在第三资源上向网络设备不发送承载第二UCI的PUCCH。相应的，网络设备在第二资源上接收来自第一终端设备的承载第一UCI的PUCCH，且网络设备在第三资源上不接收来自第一终端设备的承载第二UCI的PUCCH。
需要说明的是，“丢弃第二资源上的第一UCI”可以理解为是“丢弃第二资源上的PUCCH”，或者可以理解为是“丢弃第二资源上承载第一UCI的PUCCH”。并且，“丢弃第二资源上的第一UCI”之后，第一UCI还可以在其它资源上传输，例如在其它资源上传输承载该UCI的PUCCH或者PUSCH，或者在第二资源上传输承载该UCI的PUSCH。同样的，“丢弃第三资源上的第二UCI”可以理解为是“丢弃第三资源上的PUCCH”，或者可以理解为是“丢弃第三资源上承载第二UCI的PUCCH”。并且，“丢弃第三资源上的第二UCI”之后，第二UCI还可以在其它资源上传输，例如在其它资源上传输承载该UCI的PUCCH或者PUSCH，或者在第三资源上传输承载该UCI的PUSCH。
“不接收第二资源上的第一UCI”可以理解为是“不检测第二资源”，或者可以理解为是“不检测第二资源上的PUCCH”，或者可以理解为是“不检测第二资源上承载第一UCI的PUCCH”。同样的，“不接收第三资源上的第二UCI”可以理解为是“不检测第三资源”，或者可以理解为是“不检测第三资源上的PUCCH”，或者可以理解为是“不检测第三资源上承载第二UCI的PUCCH”。
示例性的，丢弃的UCI是满足预设条件的。S504a的实现过程可以例如但不限于如下介绍：第一终端设备根据UCI的优先级和/或传输UCI的资源起始位置，从第一UCI和第二UCI中确定待丢弃的UCI。其中，“UCI的优先级”包括第一UCI的优先级、第二UCI的优先级。“传输UCI的资源起始位置”包括第一资源在时域上的起始位置、第二资源在时域上的起始位置。
以上述“情况1”为例，S504a具体实现为：当第一UCI满足预设条件，第一终端设备丢弃第二资源上的第一UCI。
其中，第一UCI满足的预设条件包括以下至少一项：
第一项、第一UCI的优先级低于第二UCI的优先级，可以例如但不限于如下五种情况：
第一种情况、第一UCI包括SR信息和CSI中的至少一项，第二UCI包括HARQ-ACK信息。也就是说，在SR信息、CSI和HARQ-ACK信息中，HARQ-ACK信息的优先级最高。在“第二UCI包括HARQ-ACK信息”、且“第一UCI包括SR信息和CSI中的至少一项”的情况下，第一UCI的优先级低于第二UCI的优先级。
第二种情况、第一UCI包括CSI，第二UCI包括SR信息。也就是说，在SR信息和 CSI中，SR信息的优先级较高。在“第二UCI包括SR信息”、且“第一UCI包括CSI”的情况下，第一UCI的优先级低于第二UCI的优先级。
第三种情况、第一UCI包括第一优先级的CSI，第二UCI包括第二优先级的CSI。其中，第一优先级低于第二优先级。也就是说，在CSI划分为多个优先级的情况下，第一UCI中CSI的优先级低于第二UCI中CSI的优先级。其中，关于“CSI的优先级”从如下两个方面进行介绍：在优先级划分方面，作为一种实施方式，CSI用于指示下行信道质量的测量结果，CSI的优先级可以通过CSI对应的下行信道测量结果确定。或者，作为另一种实施方式，CSI的优先级可以按照CSI的类型划分，例如，“非周期的CSI”的优先级高于“半持续的CSI”的优先级，“半持续的CSI”的优先级高于“周期性的CSI”的优先级。其中，周期性的CSI可以是指，按照配置的发送周期向网络设备传输的CSI。半持续的CSI可以是指，在激活的有效时间内，按照配置的发送周期向网络设备传输的CSI，直至接收到去激活的信令。非周期性的CSI可以是指，未按照固定的周期向网络设备传输的CSI。在优先级指示方面，一个CSI包括一个优先级值(priority value)。一个CSI中的优先级值指示该CSI的优先级。一个CSI中的优先级值越小，该CSI的优先级越高。此种情况下，“第一UCI中CSI的优先级值”大于“第二UCI中CSI的优先级值”。或者，反之，一个CSI中的优先级值越大，该CSI的优先级越高。此种情况下，“第一UCI中CSI的优先级值”小于“第二UCI中CSI的优先级值”。
第四种情况、第一UCI包括第一优先级的SR信息，第二UCI包括第二优先级的SR信息。其中，第一优先级低于第二优先级。也就是说，在SR信息划分为多个优先级的情况下，第一UCI中SR信息的优先级低于第二UCI中SR信息的优先级。示例性的，一个SR信息包括一个优先级值。一个SR信息中的优先级值指示该SR信息的优先级。一个SR信息中的优先级值越小，该SR信息的优先级越高。此种情况下，“第一UCI中SR信息的优先级值”大于“第二UCI中SR信息的优先级值”。或者，反之，一个SR信息中的优先级值越大，该SR信息的优先级越高。此种情况下，“第一UCI中SR信息的优先级值”小于“第二UCI中SR信息的优先级值”。
第五种情况、第一UCI包括第一优先级的HARQ-ACK信息，第二UCI包括第二优先级的HARQ-ACK信息。其中，第一优先级低于第二优先级。也就是说，在HARQ-ACK信息划分为多个优先级的情况下，第一UCI中HARQ-ACK信息的优先级低于第二UCI中HARQ-ACK信息的优先级。示例性的，一个HARQ-ACK信息包括一个优先级值。一个HARQ-ACK信息中的优先级值指示该HARQ-ACK信息的优先级。一个HARQ-ACK信息中的优先级值越小，该HARQ-ACK信息的优先级越高。此种情况下，“第一UCI中HARQ-ACK信息的优先级值”大于“第二UCI中HARQ-ACK信息的优先级值”。或者，反之，一个HARQ-ACK信息中的优先级值越大，该HARQ-ACK信息的优先级越高。此种情况下，“第一UCI中HARQ-ACK信息的优先级值”小于“第二UCI中HARQ-ACK信息的优先级值”。
第六种情况、第一UCI的优先级值是0，第二UCI的优先级值是1。其中，优先级值越小，该优先级指示的优先级越低。也就是说，预先规定UCI的优先级，且通过优先级值来指示。此种情况下，由于第一UCI中的优先级值小于第二UCI中的优先级值，所以，第一UCI的优先级低于第二UCI的优先级。
第七种情况、第一UCI的优先级值是1，第二UCI的优先级值是0。其中，优先级值越小，该优先级指示的优先级越高。也就是说，预先规定UCI的优先级，且通过优先级值来指示。此种情况下，由于第一UCI中的优先级值大于第二UCI中的优先级值，所以，第一UCI的优先级低于第二UCI的优先级。
第二项、传输第一UCI的第二资源晚于第三资源。例如，第二资源在时域上的起始位置晚于第三资源在时域上的起始位置。再如，第二资源在时域上的结束位置晚于第三资源在时域上的结束位置。
再以上述“情况2”为例，S504a具体实现为：当第二UCI满足预设条件，第一终端设备丢弃第三资源上的第二UCI。
其中，第二UCI满足的预设条件包括以下至少一项：
第一项、第二UCI的优先级低于第一UCI的优先级，可以例如但不限于如下五种情况：
第一种情况、第二UCI包括SR信息和CSI中的至少一项，第一UCI包括HARQ-ACK信息。也就是说，在SR信息、CSI和HARQ-ACK信息中，HARQ-ACK信息的优先级最高。在“第一UCI包括HARQ-ACK信息”、且“第二UCI包括SR信息和CSI中的至少一项”的情况下，第二UCI的优先级低于第一UCI的优先级。
第二种情况、第二UCI包括CSI，第一UCI包括SR信息。也就是说，在SR信息和CSI中，SR信息的优先级较高。在“第一UCI包括SR信息”、且“第二UCI包括CSI”的情况下，第二UCI的优先级低于第一UCI的优先级。
第三种情况、第二UCI包括第一优先级的CSI，第一UCI包括第二优先级的CSI。其中，第一优先级低于第二优先级。也就是说，在CSI划分为多个优先级的情况下，第二UCI中CSI的优先级低于第一UCI中CSI的优先级。其中，一个CSI包括一个优先级值。一个CSI中的优先级值指示该CSI的优先级。一个CSI中的优先级值越小，该CSI的优先级越高。此种情况下，“第二UCI中CSI的优先级值”大于“第一UCI中CSI的优先级值”。或者，反之，一个CSI中的优先级值越大，该CSI的优先级越高。此种情况下，“第二UCI中CSI的优先级值”小于“第一UCI中CSI的优先级值”。
第四种情况、第二UCI包括第一优先级的SR信息，第一UCI包括第二优先级的SR信息。其中，第一优先级低于第二优先级。也就是说，在SR信息划分为多个优先级的情况下，第二UCI中SR信息的优先级低于第一UCI中SR信息的优先级。示例性的，一个SR信息包括一个优先级值。一个SR信息中的优先级值指示该SR信息的优先级。一个SR信息中的优先级值越小，该SR信息的优先级越高。此种情况下，“第二UCI中SR信息的优先级值”大于“第一UCI中SR信息的优先级值”。或者，反之，一个SR信息中的优先级值越大，该SR信息的优先级越高。此种情况下，“第二UCI中SR信息的优先级值”小于“第一UCI中SR信息的优先级值”。
第五种情况、第二UCI包括第一优先级的HARQ-ACK信息，第一UCI包括第二优先级的HARQ-ACK信息。其中，第一优先级低于第二优先级。也就是说，在HARQ-ACK信息划分为多个优先级的情况下，第二UCI中HARQ-ACK信息的优先级低于第一UCI中HARQ-ACK信息的优先级。示例性的，一个HARQ-ACK信息包括一个优先级值。一个HARQ-ACK信息中的优先级值指示该HARQ-ACK信息的优先级。一个HARQ-ACK信息中的优先级值越小，该HARQ-ACK信息的优先级越高。此种情况下，“第二UCI中 HARQ-ACK信息的优先级值”大于“第一UCI中HARQ-ACK信息的优先级值”。或者，反之，一个HARQ-ACK信息中的优先级值越大，该HARQ-ACK信息的优先级越高。此种情况下，“第二UCI中HARQ-ACK信息的优先级值”小于“第一UCI中HARQ-ACK信息的优先级值”。
第六种情况、第二UCI的优先级值是0，第一UCI的优先级值是1。其中，优先级值越小，该优先级指示的优先级越低。此种情况下，由于第二UCI中的优先级值小于第一UCI中的优先级值，所以，第二UCI的优先级低于第一UCI的优先级。
第七种情况、第二UCI的优先级值是1，第一UCI的优先级值是0。其中，优先级值越小，该优先级指示的优先级越高。此种情况下，由于第二UCI中的优先级值大于第一UCI中的优先级值，所以，第二UCI的优先级低于第一UCI的优先级。
第二项、传输第二UCI的第三资源晚于第二资源。例如，第三资源在时域上的起始位置晚于第二资源在时域上的起始位置。再如，第二资源在时域上的结束位置晚于第三资源在时域上的结束位置。
示例性的，在预设条件实现为上述“第一项、第二UCI的优先级低于第一UCI的优先级”的情况下，仍以“第一UCI包括HARQ-ACK信息”为例，在图3a、图3b或图3c中，第二UCI包括CSI，满足上述第一项预设条件。所以，第一终端设备丢弃第三资源上的第二UCI，以使得优先级较高的UCI能够发送到网络设备。
示例性的，在预设条件实现为上述“第二项、传输第二UCI的第三资源晚于第二资源”的情况下，仍以“第一UCI包括HARQ-ACK信息”为例，在图3a、图3b或图3c中，第二UCI包括CSI。“传输CSI的资源”在时域上的起始位置晚于“传输HARQ-ACK信息的资源”在时域上的起始位置，即满足上述第四项预设条件。所以，第一终端设备丢弃第三资源上的第二UCI，以使得时间上较近的UCI能够发送到网络设备。
需要说明的是，在预设条件包括第一项和第二项的情况下，第一终端设备可以先判断是否满足第一项，以使第一终端设备始终能够优先发送优先级较高的UCI。在第一UCI的优先级和第二UCI的优先级相同的情况下，第一终端设备再判断是否满足第二项，以使第一终端设备优先发送时间上较近的UCI。与S504a相比，S504b的区别在于执行主体不同。S504a由第一终端设备执行，S504b由网络设备执行，S504b的实现过程可以参见S504a的相关介绍，此处不再赘述。
本申请实施例提供的上行控制信息传输方法，在第一终端设备确定第一资源与第一载波上的下行资源在时域上重叠的情况下，第一终端设备不在第一资源上发送第一UCI，而确定第二资源用于传输第一UCI。在第二资源与第三资源在时域上重叠的情况下，第一终端设备丢弃一个UCI，如第一终端设备丢弃第二资源上的第一UCI，或丢弃第三资源上的第二UCI，以使得第一终端设备无需同时发送第一UCI和第二UCI。由于第一终端设备的功率一定，在第一终端设备丢弃一个UCI的情况下，第一终端设备在某一个时刻的功率用于发送一个UCI，而非在同一时刻发送两个或两个以上的UCI，从而提升UCI的传输性能。
在一些实施方式中，在网络设备确定哪一UCI被第一终端设备丢弃的情况下，网络设备将“被第一终端设备丢弃的UCI对应的传输资源”调度给其他终端设备。下面，通过两个示例进行介绍：
示例一，网络设备确定第二资源上的第一UCI被丢弃的情况下，执行步骤如图6b中“情 况1”的虚线框所示：
步骤1、网络设备向第二终端设备发送指示信息1。相应的，第二终端设备接收来自网络设备的指示信息1。
其中，指示信息1指示第二资源用于传输第二终端设备与网络设备之间的交互信息。指示信息1可以是RRC信令，也可以是DCI。
示例二，网络设备确定第三资源上的第二UCI被丢弃的情况下，执行步骤如图6b中“情况2”的虚线框所示：
步骤2、网络设备向第二终端设备发送指示信息2。相应的，第二终端设备接收来自网络设备的指示信息2。
其中，指示信息2指示第三资源用于传输第二终端设备与网络设备之间的交互信息。指示信息2可以是RRC信令，也可以是DCI。
也就是说，当第一终端设备丢弃某一资源上的UCI的情况下，该资源未被第一终端设备利用，网络设备可以将第一终端设备未利用的资源，配置给第二终端设备，以提高资源利用率。
在一些实施方式中，参见图7，本申请实施例上行控制信息传输方法还包括S505：
S505、网络设备向第一终端设备发送指示信息3。相应的，第一终端设备接收来自网络设备的指示信息3。
其中，指示信息3指示第一终端设备丢弃第一UCI和第二UCI中的一个UCI。指示信息3可以实现为RRC信令，也可以是其他信令，本申请实施例对此不作限定。第一终端设备执行S505之后，再执行S504a。也就是说，第一终端设备根据指示信息3，确定丢弃第一UCI和第二UCI中的哪一UCI，以使网络设备能够灵活地控制第一终端设备，也能够降低第一终端设备侧的处理复杂程度。
需要说明的是，第一终端设备在执行S504a之前，执行S505即可。本申请实施例对S505与“S501、S502和S503中任一个步骤”的执行顺序不作限定。例如，第一终端设备可以先执行S505，再执行“S501、S502和S503”，或者，第一终端设备可以先执行S505，再执行“S501、S502和S503中任一个步骤”，或者，第一终端设备可以先执行“S501、S502和S503”，再执行S505，或者，第一终端设备可以先执行“S501、S502和S503中任一个步骤”，再执行S505，或者，第一终端设备可以同时执行S505和“S501、S502和S503中任一个步骤”。
在一些实施方式中，对于“第一终端设备丢弃的UCI”而言，第一终端设备有如下两种处理方式：
处理方式一、第一终端设备不在“PUCCH组中的其他载波”上发送“S504a中丢弃的UCI”。以“图7中的情况1”为例，第一终端设备丢弃第二资源上的第一UCI，且第一终端设备也不在“PUCCH组中除第二载波之外的其他载波”上发送上述第一UCI。以“图7中的情况2”为例，第一终端设备丢弃第三资源上的第二UCI，且第一终端设备也不在“PUCCH组中除第三载波之外的其他载波”上发送上述第二UCI。
此种处理方式下，S504可以有如下实现方式：
第一终端设备丢弃第二资源上的第一UCI，且第一终端设备在“PUCCH组中除第二载波之外的其他载波”上不发送上述第一UCI，第一终端设备在第三资源上向网络设备发送第 二UCI。相应的，网络设备确定第二资源上的第一UCI被丢弃，且网络设备在“PUCCH组中除第二载波之外的其他载波”上不接收来自第一终端设备的第一UCI，网络设备在第三资源上接收来自第一终端设备的第二UCI。
或者，第一终端设备丢弃第三资源上的第二UCI，且第一终端设备在“PUCCH组中除第三载波之外的其他载波”上不发送上述第二UCI，第一终端设备在第二资源上向网络设备发送第一UCI。相应的，网络设备确定第三资源上的第二UCI被丢弃，且网络设备在“PUCCH组中除第三载波之外的其他载波”上不接收来自第一终端设备的第二UCI，网络设备在第二资源上接收来自第一终端设备的第一UCI。
处理方式二、第一终端设备在其他载波上发送“第一终端设备丢弃的UCI”。以“图8中的情况1”为例，第一终端设备丢弃第二资源上的第一UCI，但第一终端设备在“PUCCH组中除第二载波之外的其他载波”上发送上述第一UCI。其中，“PUCCH组中除第二载波之外的其他载波”可以是第三载波，即第一UCI和第二UCI通过同一载波发送。以“图8中的情况2”为例，第一终端设备丢弃第三资源上的第二UCI，但第一终端设备在“PUCCH组中除第三载波之外的其他载波”上发送上述第二UCI。其中，“PUCCH组中除第三载波之外的其他载波”可以是第二载波，即第一UCI和第二UCI通过同一载波发送。
此种处理方式下，S504可以有如下实现方式：
第一终端设备丢弃第二资源上的第一UCI，但第一终端设备在“PUCCH组中除第二载波之外的其他载波”上发送上述第一UCI。相应的，网络设备确定第二资源上的第一UCI被丢弃，但网络设备在“PUCCH组中除第二载波之外的其他载波”上接收来自第一终端设备的第一UCI。
或者，第一终端设备丢弃第三资源上的第二UCI，但第一终端设备在“PUCCH组中除第三载波之外的其他载波”上发送上述第二UCI。相应的，网络设备确定第三资源上的第二UCI被丢弃，但网络设备在“PUCCH组中除第三载波之外的其他载波”上接收来自第一终端设备的第二UCI。
其中，当在同一载波上发送第一UCI和第二UCI时，第一终端设备向网络设备发送承载第一UCI的PUCCH，以及承载第二UCI的PUCCH。相应的，网络设备接收来自第一终端设备的承载第一UCI的PUCCH，以及承载第二UCI的PUCCH。或者，第一终端设备向网络设备发送承载第一UCI和第二UCI的PUCCH。相应的，网络设备接收来自第一终端设备的承载第一UCI和第二UCI的PUCCH。
处理方式二可以预先约定，也可以由网络设备指示。在“网络设备指示第一终端设备采用处理方式二”的情况下，参见图8，第一终端设备还执行S506：
S506、网络设备向第一终端设备发送指示信息4。相应的，第一终端设备接收来自网络设备的第二指示信息4。
其中，指示信息4指示第一终端设备在同一载波上发送第一UCI和第二UCI。指示信息4可以为RRC信令，也可以是其他信令，本申请实施例对此不作限定。也就是说，经过S504a之后，即使第一终端设备丢弃第二资源上的第一UCI，但第一终端设备还在第三载波上向网络设备发送第一UCI。即使第一终端设备丢弃第三资源上的第二UCI，但第一终端设备还在第二载波上向网络设备发送第二UCI。
需要说明的是，指示信息3和指示信息4可以是同一消息，也可以是不同消息，本申 请实施例对此不作限定。
处理方式二中，在“通过同一载波传输第一UCI和第二UCI”的情况下，UCI传输过程介绍如下：
首先，以“第一终端设备丢弃第二资源上的第一UCI”为例，参见图8中“情况1”虚线框所示，第一终端设备还执行S507a：
S507a、第一终端设备确定在第三载波上的目标资源1。
其中，目标资源1是基于第二资源确定的。目标资源1可以但不限于如下四种情况：
第一种情况，目标资源1与第二资源的符号数量相同，但在时域起始位置上不同。
第二种情况，目标资源1与第二资源的符号数量不同，但在时域起始位置上相同。
第三种情况，目标资源1与第二资源的符号数量不同，且在时域起始位置上不同。示例性的，目标资源1的符号数量是基于第二资源的符号数量确定的。
第四种情况，目标资源1与第二资源的符号数量相同，且在时域起始位置上相同。
其中，目标资源1与第三资源是同一载波上的资源。并且，目标资源1与第三资源在时域上可能重叠，也可能不重叠。在“目标资源1与第三资源在时域上不重叠”的情况下，第一UCI和第二UCI的传输过程如下：
S507b、第一终端设备确定在目标资源1上向网络设备发送第一UCI，以及在第三资源上向网络设备发送第二UCI。相应的，网络设备在目标资源1上接收来自第一终端设备的第一UCI，以及在第三资源上接收来自第一终端设备的第二UCI。
在“目标资源1与第三资源在时域上重叠”的情况下，第一UCI和第二UCI以复用的方式传输，也就是说，第一UCI和第二UCI复用后在一个PUCCH上传输。具体介绍如下：
S507c、第一终端设备确定在第三载波上的复用资源1。
其中，复用资源1是基于第二资源和第三资源确定的资源。复用资源1可以但不限于如下其中一项：第三资源、第三载波上区别于第三资源的另一资源，如第六资源。
示例性的，第一UCI包括的比特数量为两个，第二资源上的PUCCH能够承载UCI的比特数量至少为两个。第二UCI包括的比特数量为两个，第三资源上的PUCCH能够承载UCI的比特数量至少为两个。由于第一UCI和第二UCI以复用的方式传输，所以，复用资源1上的PUCCH至少能够承载UCI的比特数量是4个。在第三资源上的PUCCH能够承载4比特的UCI的情况下，复用资源1可以为第三资源。当然，第一终端设备也可以在第三载波上确定一个与第三资源不同的资源，如第六资源。
S507d、第一终端设备确定在复用资源1上向网络设备发送第一UCI和第二UCI。相应的，网络设备在复用资源1上接收来自第一终端设备的第一UCI和第二UCI。
需要说明的是，网络设备同样执行S507a，以确定在哪些资源上接收第一UCI。或者网络设备同样执行S507a和S507c，以确定在哪些资源上接收第一UCI和第二UCI。
如此，第一终端设备通过上述“处理方式二”，在同一载波上向网络设备发送第一UCI和第二UCI，既能够避免“跨载波上PUCCH资源冲突”，又能够使得第一UCI正常传输。
然后，以“第一终端设备丢弃第三资源上的第二UCI”为例，参见图8中“情况2”虚线框所示，第一终端设备还执行S507e：
S507e、第一终端设备确定在第二载波上的目标资源2。
其中，目标资源2是基于第三资源确定的。目标资源2可以但不限于如下四种情况：
第一种情况，目标资源2与第三资源的符号数量相同，但在时域起始位置上不同。
第二种情况，目标资源2与第三资源的符号数量不同，但在时域起始位置上相同。
第三种情况，目标资源2与第三资源的符号数量不同，且在时域起始位置上不同。示例性的，目标资源2的符号数量是基于第三资源的符号数量确定的。
第四种情况，目标资源2与第三资源的符号数量相同，且在时域起始位置上相同。
示例性的，以图9为例，第一UCI包括HARQ-ACK信息，第一UCI是从主载波切换至辅载波1之后，在辅载波1上传输的信息，如图9中的曲线箭头所示。第二载波为辅载波1，第二资源为辅载波1上符号索引4至符号索引11对应的资源。第二UCI包括CSI，第三载波为主载波，第三资源为主载波上符号索引11至符号索引13对应的资源。第二UCI的优先级低于第一UCI的优先级，主载波上的第二UCI(即CSI)被丢弃，且在辅载波1上传输，如图9中的曲线箭头所示。目标资源2基于第三资源确定，满足上述第四种情况，即目标资源2是辅载波1上符号索引11至符号索引13对应的资源。
其中，目标资源2与第二资源是同一载波上的资源。并且，目标资源2与第二资源在时域上可能重叠。示例性的，仍以图9为例，第一UCI包括HARQ-ACK信息，第二载波为辅载波1，第二资源为辅载波1上符号索引4至符号索引11对应的资源。目标资源2是辅载波1上符号索引11至符号索引13对应的资源。也就是说，目标资源2与第二资源在时域上重叠。目标资源2与第二资源在时域上也可能不重叠。在“目标资源2与第二资源在时域上不重叠”的情况下，第一UCI和第二UCI的传输过程如下：
S507f、第一终端设备确定在目标资源2上向网络设备发送第二UCI，以及在第二资源上向网络设备发送第一UCI。相应的，网络设备在目标资源2上接收来自第一终端设备的第二UCI，以及在第二资源上接收来自第一终端设备的第一UCI。
在“目标资源2与第二资源在时域上重叠”的情况下，第一UCI和第二UCI以复用的方式传输，具体介绍如下：
S507g、第一终端设备确定在第二载波上的复用资源2。
其中，复用资源2是基于第二资源和第三资源确定的资源。复用资源2可以但不限于如下其中一项：第二资源、第二载波上区别于第二资源的另一资源，如第七资源。
示例性的，仍以图9为例，第一UCI包括HARQ-ACK信息，第二载波为辅载波1，第二资源为辅载波1上符号索引4至符号索引11对应的资源。第二UCI包括CSI，第三载波为主载波，第三资源为主载波上符号索引11至符号索引13对应的资源。复用资源2是基于第二资源(如图9中辅载波1上“HARQ-ACK”所在框对应的资源)和第三资源(如图9中辅载波1上“CSI”所在框对应的资源)确定的。复用资源2可以是辅载波1上“HARQ-ACK+CSI”所在框对应的资源。
S507h、第一终端设备确定在复用资源2上向网络设备发送第一UCI和第二UCI。相应的，网络设备在复用资源2上接收来自第一终端设备的第一UCI和第二UCI。
需要说明的是，网络设备同样执行S507a，以确定在哪些资源上接收第一UCI。或者网络设备同样执行S507a和S507c，以确定在哪些资源上接收第一UCI和第二UCI。
如此，第一终端设备通过上述“处理方式二”，在同一载波上向网络设备发送第一UCI和第二UCI，既能够避免“跨载波上PUCCH资源冲突”，又能够避免“未向网络设备发送第二UCI”的现象。
在一些实施方式中，以“第二资源上传输的第一UCI被丢弃”为例，参见图10中“情况1”虚线框所示，当第二资源与第二载波上的PUSCH资源在时域上重叠的情况下，第一终端设备还执行S508：
S508、第一终端设备确定在第二载波的PUSCH资源上向网络设备发送第一UCI。相应的，网络设备在第二载波的PUSCH资源上接收来自第一终端设备的第一UCI。
示例性的，仍以“第一UCI为HARQ-ACK信息”为例，参见图11，第二载波为辅载波1，第二资源是辅载波1上符号索引4至符号索引11对应的资源。并且，辅载波1上符号索引4至符号索引11对应的资源为PUSCH资源。也就是说，第二载波上的PUSCH资源与第二资源重叠。此种情况下，第一终端设备将第二载波上的PUSCH上承载的信息和第一UCI进行复用，利用第二载波上的PUSCH资源向网络设备发送第一UCI，第一终端设备不再通过第二资源向网络设备发送第一UCI，以避免“跨载波上PUCCH资源冲突”的问题，使得第一UCI正常传输，从而提升UCI的传输性能。
再以“第三资源上传输的第二UCI被丢弃”为例，参见图10中“情况2”虚线框所示，当第三资源与第三载波上的PUSCH资源在时域上重叠的情况下，第一终端设备还执行S509：
S509、第一终端设备确定在第三载波的PUSCH资源上向网络设备发送第二UCI。相应的，网络设备在第三载波的PUSCH资源上接收来自第一终端设备的第二UCI。
也就是说，第一终端设备将第三载波上的PUSCH上承载的信息与第二UCI进行复用，利用第三载波上的PUSCH资源向网络设备发送第二UCI，第一终端设备不再通过第三资源向网络设备发送第二UCI，以避免“跨载波上PUCCH资源冲突”的问题，又能够使得第二UCI正常传输，从而提升UCI的传输性能。
需要说明的是，在第一终端设备执行S503之后，第一终端设备也可以不执行S504a，而执行S508(或S509)。相应的，在网络设备执行S503之后，网络设备也可以不执行S504b，而执行S508(或S509)，以解决“跨载波上PUCCH资源冲突”的问题。
需要说明的是，在第三载波与第二载波是同一载波的情况下，第一终端设备基于S504确定丢弃第一UCI和第二UCI中的哪一UCI。或者，将第一UCI与第二UCI以复用的方式传输。
在“第一UCI与第二UCI以复用的方式”传输的情况下，若复用方式传输第一UCI和第二UCI时，占用的资源未与下行资源重叠，则第一UCI和第二UCI以复用的方式通过第三载波(即第二载波)传输。示例性的，仍以图9为例，第二载波和第三载波为辅载波1。第一UCI包括HARQ-ACK信息，第二UCI包括CSI。复用方式传输第一UCI和第二UCI时，占用的资源是辅载波1上符号索引4至符号索引1对应的资源，如图9中“HARQ-ACK+CSI”所在方框对应的资源。第一UCI和第二UCI以复用的方式在“辅载波1上符号索引4至符号索引1对应的资源”上传输。
若复用方式传输第一UCI和第二UCI时，占用的资源与下行资源重叠，则第一UCI和第二UCI以复用的方式通过第五载波传输，具体“第五载波上用于传输第一UCI和第二UCI的资源”确定过程可以参见图13中“方式一”的介绍，此处不再赘述。
另外，作为一种可能的实现方式，第一终端设备在执行S501之后，第一终端设备不执行S502，而是执行如下步骤：
步骤1、第一终端设备确定在第一载波的第七资源上向网络设备发送第一UCI。相 应的，网络设备确定在第一载波的第七资源上接收来自网络设备的第一UCI。
其中，第七资源包括第一载波的上行符号或灵活符号。第七资源与第一资源是同一时域资源单元中的资源。时域资源单元可以是以下其中一项：时隙、子时隙、子帧、或者无线帧。
示例性的，以图12a所示，第一UCI为HARQ-ACK信息，第一载波为主载波，第一资源为主载波上符号索引1至符号索引3对应的资源，如图12a中上侧虚线方框中“HARQ-ACK”对应的资源位置。主载波上与第一资源位于同一时隙内的灵活符号的符号索引为“符号索引11至符号索引13”。第一资源与上述灵活符号在符号数量上相同，也就是说，第一UCI可以承载于上述灵活符号。主载波上符号索引1至符号索引3对应的资源不再用于传输第一UCI，上述灵活符号实现为第七资源，用于传输第一UCI，如图12a中下侧虚线方框中曲线箭头所示。第一终端设备在主载波的“符号索引11至符号索引13对应的符号”上向网络设备发送第一UCI。相应的，网络设备在主载波的“符号索引11至符号索引13对应的符号”上接收来自网络设备的第一UCI。也就是说，即使第一资源与下行资源在时域上重叠，第一终端设备也不进行“载波切换”处理，仍在原来的载波上确定用于传输第一UCI的资源。
在一些实施方式中，上述第七资源还用于传输第二UCI。此种情况下，步骤1实现为：第一终端设备确定在第一载波的第七资源上向网络设备发送第一UCI和第二UCI。相应的，网络设备确定在第一载波的第七资源上接收来自网络设备的第一UCI和第二UCI。
其中，HARQ-ACK信息和CSI以复用的方式传输，即HARQ-ACK信息和CSI以一个PUCCH传输。第七资源作为复用的资源。
示例性的，以图12b所示，第一UCI包括HARQ-ACK信息，第一载波为主载波，第一资源为主载波上符号索引1至符号索引3对应的资源，如图12b中上侧虚线方框中“HARQ-ACK”对应的资源位置。主载波上与第一资源位于同一时隙内的灵活符号的符号索引为“符号索引11至符号索引13”。上述灵活符号用于传输第一UCI，如图12b中下侧虚线方框中曲线箭头所示。由于上述灵活符号还用于传输第二UCI，第二UCI包括CSI，如图12b中上侧虚线方框中“CSI”对应的资源位置。此种情况下，第七资源作为复用资源，用于发送一个PUCCH，以传输HARQ-ACK信息和CSI，如图12b中下侧虚线方框中“HARQ-ACK+CSI”对应的资源位置。
需要说明的是，在第七资源还用于传输第二UCI的情况下，第一UCI和第二UCI以复用的方式传输，此种情况下，承载第一UCI和第二UCI的资源(如图12c中间虚线方框中“HARQ-ACK+CSI”的方框所示的资源)与下行资源重叠。第一终端设备执行S504a，丢弃一个UCI。以图12c为例，第一终端设备丢弃第二UCI，且第一终端设备仍在“符号索引11至符号索引13对应的符号”上向网络设备发送第一UCI。相应的，网络设备仍在“符号索引11至符号索引13对应的符号”上接收来自网络设备的第一UCI。
另外，作为再一种可能的实现方式，如图13所示，本申请实施例还包括如下方式：
S1301、第一终端设备确定第一载波上的第一资源。
其中，第一载波可以是主载波，也可以是辅载波，详见S501的描述，此处不再赘述。
其中，“第一资源”的介绍包括如下两个方面：
第一方面，第一资源用于传输第一UCI，具体可以参见S501的相关说明，此处不再赘述。
第二方面，第一资源与第一载波上的第二资源在时域上重叠。其中，第二资源是第一载波上传输第二UCI的资源。第二UCI包括的信息可以例如但不限于如下至少一项：HARQ-ACK信息、SR信息和CSI。第一UCI中的信息类型和第二UCI中的信息类型可以相同，也可以不同，本申请实施例对此不作限定。
示例性的，参见图14中的(a)，第一载波是主载波。第一UCI包括HARQ-ACK信息，第一资源是主载波上符号索引5至13对应的资源。第二UCI包括CSI，第二资源是主载波上符号索引11至13对应的资源。第一资源与第二资源在时域上重叠。
示例性的，参见图15中的(a)，第一载波是主载波。第一UCI包括HARQ-ACK信息，第一资源是主载波上符号索引11至13对应的资源。第二UCI包括CSI，第二资源是主载波上符号索引11至13对应的资源。第一资源与第二资源在时域上重叠。
S1302、第一终端设备确定第一载波上的第八资源。
其中，第八资源是复用的资源，第八资源是基于第一资源和第二资源确定的资源。第八资源用于传输第一UCI和第二UCI。第一UCI和第二UCI以复用的方式传输。第八可以但不限于如下其中一项：第一资源、第二资源、第一载波上区别于第一资源和第二资源的另一资源。
示例性的，仍以图14中的(a)为例，第一载波是主载波。第一UCI包括HARQ-ACK信息，第一资源是主载波上符号索引5至13对应的资源。第二UCI包括CSI，第二资源是主载波上符号索引11至13对应的资源。第一资源与第二资源在时域上重叠。此种情况系，第八资源是主载波上符号索引3至12对应的资源，如图14中的(b)中“HARQ-ACK+CSI”所在方框对应的资源。第八资源的确定过程可以参见S507c的介绍，此处不再赘述。
示例性的，仍以图15中的(a)为例，第一载波是主载波。第一UCI包括HARQ-ACK信息，第一资源是主载波上符号索引11至13对应的资源。第二UCI包括CSI，第二资源是主载波上符号索引11至13对应的资源。第一资源与第二资源在时域上重叠。此种情况系，第八资源是主载波上符号索引8至13对应的资源，如图15中的(b)中“HARQ-ACK+CSI”所在方框对应的资源。第八资源的确定过程可以参见S507c的介绍，此处不再赘述。
其中，第八资源是复用的资源与第一载波上的下行资源在时域上可能重叠，也可能不重叠。在“第八资源与第一载波上的下行资源在时域上不重叠”的情况下，第一终端设备在第八资源上向网络设备发送第一UCI和第二UCI。相应的，网络设备在第八资源上接收来自第一终端设备的第一UCI和第二UCI。
在“第八资源与第一载波上的下行资源在时域上重叠”的情况下，第一终端设备可以但不限于如下两种处理方式：
方式一、如图13中“方式1”的虚线方框所示：
S1303、第一终端设备确定第二载波上的第九资源。
其中，第二载波的介绍可以参见S502的相关说明，此处不再赘述。
其中，第九资源是基于第八资源确定的资源，如第九资源与第八资源在符号数量上相同，且在时域起始位置上相同。
示例性的，仍以图14中的(b)为例，第一载波是主载波，第八资源是主载波上符号索引3至12对应的资源，如图14中的(b)中“HARQ-ACK+CSI”所在方框对应的资源。第二载波是辅载波1，第八资源不再用于发送复用后的HARQ-ACK信息(即第一UCI)和CSI(即第二UCI)。第九资源是辅载波1上符号索引3至12对应的资源，第九资源用于发送复用后的HARQ-ACK信息(即第一UCI)和CSI(即第二UCI)如图14中的(c)中曲线箭头所示。
S1304、第一终端设备在第九资源上向网络设备发送第一UCI和第二UCI。相应的，网络设备在第九资源上接收来自第一终端设备的第一UCI和第二UCI。
如此，在同一载波上，第一资源和第二资源在时域上重叠的情况下，第一终端设备确定在第八资源上以复用的方式传输第一UCI和第二UCI。在第八资源与第一载波上的下行资源在时域上重叠的情况下，第一终端设备在其他载波，如第二载波上，以复用的方式传输第一UCI和第二UCI，以保证UCI的传输性能。
方式二、如图13中“方式2”的虚线方框所示：
S1305、第一终端设备丢弃第一资源上的第一UCI或者丢弃第二资源上的第二UCI。相应的，网络设备确定第一资源上的第一UCI被丢弃或者第二资源上的第二UCI被丢弃。其中，网络设备同样执行S1301、S1302和S1303。
也就是说，对于第一终端设备而言，第一终端设备执行S1305a：
S1305a、第一终端设备丢弃第一资源上的第一UCI或者丢弃第二资源上的第二UCI。
也就是说，对于网络设备而言，网络设备执行S1305b：
S1305b、网络设备确定第一资源上的第一UCI被丢弃或者第二资源上的第二UCI被丢弃。其中，S1305b的实现过程可以参见S1305a的相关说明，此处不再赘述。
示例性的，仍以图15中的(b)为例，第一载波是主载波。第一UCI包括HARQ-ACK信息，第一资源是主载波上符号索引11至13对应的资源。第二UCI包括CSI，第二资源是主载波上符号索引11至13对应的资源。第一UCI的优先级高于第二UCI的优先级，第一终端设备确定丢弃第二UCI，即CSI。
针对未被丢弃的UCI，第一终端设备的处理过程可以例如如下介绍：
在“未被丢弃的UCI的传输资源与下行资源”在时域上不重叠的情况下，第一终端设备向网络设备发送“未被丢弃的UCI”。示例性的，通过两种情况进行说明：
情况1、在“第一终端设备丢弃第一资源上的第一UCI”的情况下，第二资源与第一载波上的下行资源在时域上不重叠，第一终端设备还在第二资源上向网络设备发送第二UCI。相应的，网络设备在第二资源上接收来自第一终端设备的第二UCI，如图13中“情况1”的虚线方框所示。
情况2、在“第一终端设备丢弃第二资源上的第二UCI”的情况下，第一资源与第一载波上的下行资源在时域上不重叠，第一终端设备还在第一资源上向网络设备发送第一UCI。相应的，网络设备在第一资源上接收来自第一终端设备的第一UCI，如图13中“情况2”的虚线方框所示。
示例性的，仍以图15中的(b)为例，第一终端设备确定丢弃第二UCI，即CSI。第一载波是主载波。第一UCI包括HARQ-ACK信息，第一资源是主载波上符号索引11至13对应的资源。第一终端设备还在“主载波上符号索引11至13对应的资源”上向网络设备 发送第一UCI。相应的，网络设备在“主载波上符号索引11至13对应的资源”上接收来自第一终端设备的第一UCI，如图15中的(c)所示。
在“未被丢弃的UCI的传输资源与下行资源”在时域上重叠的情况下，仍通过两种情况进行说明：
情况1、在“第一终端设备丢弃第一资源上的第一UCI”的情况下，第二资源与第一载波上的下行资源在时域上重叠，第一终端设备向网络设备不发送第一UCI，或者，第一终端设备执行“方式一”中的S1303和S1304，以向网络设备传输第一UCI和第二UCI，以提高UCI的传输性能。
情况2、在“第一终端设备丢弃第二资源上的第二UCI”的情况下，第一资源与第一载波上的下行资源在时域上重叠，第一终端设备向网络设备不发送第二UCI，或者，第一终端设备执行“方式一”中的S1303和S1304，以向网络设备传输第一UCI和第二UCI，以提高UCI的传输性能。
如此，在同一载波上，第一资源和第二资源在时域上重叠的情况下，第一终端设备确定在第八资源上以复用的方式传输第一UCI和第二UCI。在第八资源与第一载波上的下行资源在时域上重叠的情况下，第一终端设备丢弃第一UCI和第二UCI中的一个UCI，从而向网络设备传输一个UCI，以提升UCI的传输性能。
本申请实施例提供一种上行控制信息传输方法，该上行控制信息传输方法应用在上行控制信息的传输过程中。参见图16，该上行控制信息传输方法包括如下步骤：
S1601、终端设备确定第一载波上的第一资源。
其中，第一载波可以是主载波，也可以是辅载波。
其中，第一资源用于传输第一UCI，且第一资源与第一载波上的下行资源在时域上重叠。S1601的具体介绍和实现过程可以参见S501的相关说明，此处不再赘述。
示例性的，以图18为例，第一载波为主载波。第一资源是主载波上符号索引4至符号索引10对应的资源，第一UCI包括HARQ-ACK信息。下行资源是主载波上符号索引0至符号索引10对应的资源。也就是说，第一资源与下行资源在时域上重叠。
S1602、终端设备确定第二载波上的第二资源。
其中，第一载波和第二载波是两个不同的载波。在第一载波是主载波的情况下，第二载波可以是辅载波。在第一载波是辅载波的情况下，第二载波可以是另一辅载波。或者，在第一载波是辅载波的情况下，第二载波可以是主载波。
其中，第二资源用于传输第一UCI。第二资源满足预设条件，预设条件包括：第二资源与第三资源在时域上不重叠。
其中，第三资源是第三载波上用于传输第二UCI的资源。第三载波是终端设备用于发送UCI的载波中除第二载波之外的任意一个载波。第二UCI是终端设备发送的UCI中除第一UCI的任意一个UCI。其中，第三载波与第一载波可以是同一载波，也可以是不同载波，本申请实施例对此不作限定。
示例性的，仍以图18为例，第一UCI包括HARQ-ACK信息，第二UCI包括CSI。第二载波为辅载波1，第二资源是辅载波1上符号索引4至符号索引10对应的资源。第三载波与第一载波为同一载波。第三资源是主载波上符号索引11至符号索引13对应的资源。第二资源与第三资源在时域上不重叠。
S1603、终端设备在第二资源上向网络设备发送第一UCI，以及在第三资源上向网络设备发送第二UCI。相应的，网络设备在第二资源上接收来自终端设备的第一UCI，以及在第三资源上接收来自终端设备的第二UCI。其中，网络设备同样执行S1601和S1602，以获知在哪些资源上接收第一UCI和第二UCI。
示例性的，仍以图18为例，第二资源是辅载波1上符号索引4至符号索引10对应的资源，第一UCI包括HARQ-ACK信息。终端设备在“辅载波1上符号索引4至符号索引10对应的资源”上向网络设备发送第一UCI。相应的，网络设备在“辅载波1上符号索引4至符号索引10对应的资源”上接收来自终端设备的第一UCI。
第三资源是主载波上符号索引11至符号索引13对应的资源，第二UCI包括CSI。终端设备在“主载波上符号索引11至符号索引13对应的资源”第三资源上向网络设备发送第二UCI。相应的，网络设备在“主载波上符号索引11至符号索引13对应的资源”上接收来自终端设备的第一UCI。
需要说明的是，网络设备同样执行S1601和S1602，以获知在哪些资源上接收第一UCI和第二UCI。
如此，在终端设备确定第一资源与第一载波上的下行资源在时域上重叠的情况下，终端设备不在第一资源上发送第一UCI，而确定第二资源用于传输第一UCI。由于第二资源是满足预设条件的资源，即第二资源与第三资源在时域上不重叠。也就是说，由于第二资源是满足预设条件的资源，所以，终端设备重新确定的第二资源与其他载波上传输UCI的资源(如第三资源)在时域上不重叠。此种情况下，终端设备不存在同时发送第一UCI和第二UCI的情况。由于终端设备的功率是固定的，在终端设备确定的第二资源与第三资源不重叠的情况下，终端设备在某一个时刻的功率用于发送一个UCI，而非在同一时刻发送两个或两个以上的UCI，从而提升UCI的传输性能。
在一些实施方式中，S1602实现为S1602a，如图17的“方式1”所示：
S1604、网络设备向终端设备发送RRC信令。相应的，终端设备接收来自网络设备的RRC信令。
其中，RRC信令指示PUCCH资源。RRC信令指示以下信息中的至少一项：一个或多个PUCCH资源集合、每个PUCCH资源集合中的PUCCH资源、或每个PUCCH资源集合中的PUCCH可以包括UCI的最大比特数。其中，每个PUCCH资源集合中的PUCCH资源可以是：PUCCH的起始符号位置、PUCCH的符号个数、或PUCCH的频域位置等。
S1602a、终端设备确定PUCCH资源中满足预设条件的资源为第二资源。
其中，PUCCH资源是S1604中RRC信令指示的资源。也就是说，网络设备根据预设条件，进行资源选择，以筛选出满足预设条件的资源，作为第二资源，然后通过RRC信令指示给终端设备，从而避免“PUCCH载波切换”之后与其他载波上的PUCCH资源在时域上重叠的现象。
在另一些实施方式中，S1602实现为S1602b，如图17的“方式2”所示：
S1604、网络设备向终端设备发送RRC信令。相应的，终端设备接收来自网络设备的RRC信令。
其中，RRC信令指示PUCCH的时域资源。RRC信令指示以下信息中的至少一项： 一个或多个PUCCH资源集合、每个PUCCH资源集合中的PUCCH资源、或每个PUCCH资源集合中的PUCCH可以包括UCI的最大比特数。其中，每个PUCCH资源集合中的PUCCH资源可以是：PUCCH的起始符号位置、PUCCH的符号个数、或PUCCH的频域位置等。
S1605、网络设备向终端设备发送DCI。相应的，终端设备接收来自网络设备的DCI。
其中，DCI指示PUCCH的时域资源，且PUCCH的时域资源与第三资源在时域上不重叠。DCI指示的PUCCH的时域资源属于S1604中RRC信令指示的PUCCH资源。也就是说，RRC信令用于为终端设备配置多个PUCCH的时域资源。DCI用于为终端设备指示使用哪个PUCCH的时域资源。
S1602b、终端设备确定PUCCH的时域资源，确定第二资源。
也就是说，网络设备根据预设条件，在RRC信令指示的PUCCH资源中进行资源选择，以筛选出满足预设条件的时域资源。如此，DCI指示的PUCCH的时域资源与其他载波上发送UCI的PUCCH资源在时域上不重叠。由于终端设备是基于DCI指示的PUCCH的时域资源确定的第二资源，从而避免“PUCCH载波切换”之后与其他载波上的PUCCH资源在时域上重叠的现象。
在一些实施方式中，第二资源与第三资源在时域上间隔至少N个时域资源单元，其中，N为正整数。也就是说，第二资源与第三资源之间有使得终端设备完成载波切换的时间间隔，以使终端设备能够及时地从第二载波切换至第三载波，提高了第二UCI发送成功的可能性，从而提升了UCI的传输性能。其中，时域资源单元是基于第二资源的子载波间隔和第三资源的子载波间隔中较小的子载波间隔确定的。由于子载波间隔越小，一个时域资源单元，例如符号或时隙对应的时间长度越大，以为终端设备切换载波提供充足的时间。
另外，在终端设备需要在不同的载波上发送UCI的情况下，如图19a所示，终端设备先在辅载波1上向网络设备发送HARQ-ACK信息。然后，终端设备再在主载波上向网络设备发送CSI。终端设备需要从辅载波1切换到主载波上，由于终端设备的自身能力有限，尤其在带内(intra-band)载波聚合(carrier aggregation，CA)场景下，终端设备无法及时切换到主载波上，从而无法及时在主载波上发送CSI，影响UCI的传输性能。
本申请实施例提供一种上行控制信息传输方法，该上行控制信息传输方法应用在上行控制信息的传输过程中。参见图19b，该上行控制信息传输方法包括如下步骤：
S1901、终端设备确定第一资源与第二资源之间的时间间隔(gap)。
其中，第一资源用于在第一载波上传输第一UCI，第二资源用于在第二载波上传输第二UCI。
示例性的，第一UCI可以是未经过“PUCCH载波切换”处理，确定在第一载波上发送的信息。第一UCI也可以是经过“PUCCH载波切换”处理，确定在第一载波上发送的信息。也就是说，终端设备确定第一资源与第二资源之间的时间间隔之前，终端设备还执行如下步骤1和步骤2：
步骤1、终端设备确定第三载波上的第三资源。
其中，第三资源用于传输第一UCI，且第三资源与第三载波上的下行资源在时域 上重叠。
示例性的，参见图18，第三资源是主载波上符号索引4至符号索引10对应的资源，与下行符号重叠。
步骤2、终端设备确定在第一载波上的第一资源上发送第一UCI。
示例性的，参见图18，第一资源是辅载波1上符号索引4至符号索引10对应的资源。
示例性的，第二UCI可以是未经过“PUCCH载波切换”处理，确定在第二载波上发送的信息。第二UCI也可以是经过“PUCCH载波切换”处理，确定在第二载波上发送的信息。也就是说，终端设备确定第一资源与第二资源之间的时间间隔之前，终端设备还执行如下步骤1和步骤2：
步骤1、终端设备确定第三载波上的第三资源。
其中，第三资源用于传输第二UCI，且第三资源与第三载波上的下行资源在时域上重叠。
步骤2、终端设备确定在第二载波上的第二资源上发送第二UCI。
S1902、当时间间隔小于第一预设值，终端设备丢弃第一资源上的第一UCI或者丢弃第二资源上的第二UCI。相应的，当时间间隔小于第一预设值，网络设备第一资源上的第一UCI被丢弃或者第二资源上的第二UCI被丢弃。其中，网络设备同样执行S1901。
也就是说，对于终端设备而言，终端设备执行S1902a：
S1902a、当时间间隔小于第一预设值，终端设备丢弃第一资源上的第一UCI或者丢弃第二资源上的第二UCI。
对于网络设备而言，网络设备执行S1902b：
S1902b、当时间间隔小于第一预设值，网络设备第一资源上的第一UCI被丢弃或者第二资源上的第二UCI被丢弃。其中，S902b的实现过程可以参见S1902a的相关说明，此处不再赘述。
也就是说，S1902可以有如下实现方式：
当时间间隔小于第一预设值，终端设备在第二资源上向网络设备发送第二UCI，且丢弃第一资源上的第一UCI。相应的，网络设备在第二资源上接收来自网络设备的第二UCI，且确定第一资源上的第一UCI被丢弃，如图19b中的“情况1”虚线框所示。
或者，当时间间隔小于第一预设值，终端设备丢弃第二资源上的第二UCI，且终端设备在第一资源上向网络设备发送第一UCI。相应的，网络设备确定第二资源上的第二UCI被丢弃，网络设备在第一资源上接收来自终端设备的第一UCI，如图19b中的“情况2”虚线框所示。
其中，第一预设值是基于终端设备的自身能力确定的数值。示例性的，第一预设值可以是预设数量的时域资源单元对应的时长。在第一资源的子载波间隔小于第二资源的子载波间隔的情况下，第一预设值的单位是以“第一资源对应的时域资源单元”为参考。例如，第一资源对应的子载波间隔为15kHz，第二资源对应的子载波间隔为30kHz，第一预设值是以“子载波间隔15kHz对应的符号”为准。
示例性的，终端设备具体丢弃第一UCI和第二UCI中的哪一UCI，可以参见S504 的相关说明，此处不再赘述。
如此，终端设备根据第一资源和第二资源之间的时间间隔来确定是否丢弃一个UCI。例如，在时间间隔小于第一预设值的情况下，终端设备无法及时在第一载波和第二载波之间切换，此种情况下，终端设备丢弃某一个载波上的UCI，从而使得终端设备无需在第一载波和第二载波之间切换，也就不存在“终端设备无法及时切换至某一载波发送UCI”的问题。
在一些实施方式中，终端设备还可以执行S1903：
S1903、终端设备向网络设备发送第一预设值。相应的，网络设备接收来自终端设备的第一预设值。
如此，网络设备执行S1903之后，网络设备即可基于第一预设值，确定哪些UCI被丢弃。在网络设备确定哪一UCI被丢弃的情况下，网络设备不检测“被丢弃的UCI的传输资源”，或者，将“被丢弃的UCI的传输资源”调度给其他终端设备。
本申请实施例提供一种上行控制信息传输方法，该上行控制信息传输方法应用在上行控制信息的传输过程中。参见图20，该上行控制信息传输方法包括如下步骤：
S2001、终端设备确定预设时域资源单元内PUCCH的发送次数。
其中，PUCCH至少包括承载第一UCI的PUCCH和承载第二UCI的PUCCH。第一UCI是在第一载波的第一资源上传输的信息，第二UCI是在第二载波的第二资源上传输的信息。也就是说，PUCCH在不同的载波上。第一UCI可以是未经过“PUCCH载波切换”处理，确定在第一载波上发送的信息。第一UCI也可以是经过“PUCCH载波切换”处理，确定在第一载波上发送的信息，详见S501和S502的介绍，此处不再赘述。
示例性的，时域资源单元可以是以下其中一项：时隙、子时隙、无线帧、或子帧。
例如，PUCCH包括：PUCCH1至PUCCH5，且上述5个PUCCH在发送次数上连接。也就是说，PUCCH1是在预设时域资源单元内首次发送的PUCCH，PUCCH2是在预设时域资源单元内第二次发送的PUCCH，其他可以此类推。PUCCH1在载波1上，PUCCH2在载波2上，PUCCH3在载波1上，PUCCH4在载波2上，PUCCH5在载波1上。也就是说，终端设备发送PUCCH1之后，需要切换至载波2上发送PUCCH2，然后再切换至载波1上发送PUCCH3，其他可以此类推。此种情况下，终端设备确定PUCCH的发送次数为5次，并且，终端设备确定载波切换次数为4次。或者，PUCCH1、PUCCH2和PUCCH3均在载波1上，PUCCH4、PUCCH5和PUCCH6均在载波2上。也就是说，终端设备在载波1上发送PUCCH1、PUCCH2和PUCCH3之后，需要切换至载波2上发送PUCCH4、PUCCH5和PUCCH6。此种情况下，终端设备确定PUCCH的发送次数为5次，并且，终端设备确定载波切换次数为1次。
S2002、终端设备根据PUCCH的发送次数确定丢弃第一资源上的第一UCI或者丢弃第二资源上的第二UCI。相应的，网络设备根据PUCCH的发送次数确定第一资源上的第一UCI被丢弃或者第二资源上的第二UCI被丢弃。
也就是说，对于终端设备而言，终端设备执行S2002a：
S2002a、终端设备根据PUCCH的发送次数确定丢弃第一资源上的第一UCI或者丢弃第二资源上的第二UCI。
也就是说，对于网络设备而言，网络设备执行S2002b：
S2002b、网络设备根据PUCCH的发送次数确定第一资源上的第一UCI被丢弃或者第二资源上的第二UCI被丢弃。其中，网络设备也执行S2001，S2002b的实现过程可以参见S2002a的介绍，此处不再赘述。
示例性的，S2002a的具体实现过程如下：
作为第一种可能的实现方式，终端设备根据“PUCCH的发送次数”与“载波切换次数”之间的对应关系，确定在预设时域资源单元上的“载波切换次数”。例如，一个时隙内PUCCH的发送次数为5次，此种情况下，终端设备在该时隙内切换载波的次数至多为4次。再如，一个时隙内PUCCH的发送次数为3次，此种情况下，终端设备在该时隙内切换载波的次数至多为2次。
在预设时域资源单元上的“载波切换次数”达到第二预设值的情况下，终端设备确定丢弃第一资源上的第一UCI或者丢弃第二资源上的第二UCI。反之，在预设时域资源单元上的“载波切换次数”未达到第二预设值的情况下，终端设备在第一资源上向网络设备发送第一UCI，以及在第二资源上向网络设备发送第二UCI。
其中，“终端设备丢弃第一资源上的第一UCI”可以是指，终端设备在第二资源上向网络设备发送第二UCI，且丢弃第一资源上的第一UCI。相应的，网络设备在第二资源上接收来自网络设备的第二UCI，且确定第一资源上的第一UCI被丢弃，如图20中的“情况1”虚线框所示。
“终端设备丢弃第二资源上的第二UCI”可以是指，终端设备丢弃第二资源上的第二UCI，且终端设备在第一资源上向网络设备发送第一UCI。相应的，网络设备确定第二资源上的第二UCI被丢弃，网络设备在第一资源上接收来自终端设备的第一UCI，如图20中的“情况2”虚线框所示。
其中，第二预设值是基于终端设备的自身能力确定的数值，该数值需要上报给网络设备。终端设备的自身能力可以是基于以下至少一项确定的信息：终端设备的数据处理速度、终端设备能够同时处理的数据量大小、终端设备的处理资源大小。
如此，终端设备根据预设时域资源单元内PUCCH的发送次数和第二预设值，确定是否丢弃某一个资源上的UCI，以避免由于终端设备自身能力的限制，导致终端设备无法及时在第一载波和第二载波之间切换。当终端设备丢弃某一个载波上的UCI，终端设备无需在第一载波和第二载波之间切换，也就不存在“终端设备无法及时切换至某一载波发送UCI”的问题。
在一些实施方式中，终端设备还可以执行S2003：
S2003、终端设备向网络设备发送第二预设值。相应的，网络设备接收来自终端设备的第二预设值。
如此，网络设备执行S2003之后，网络设备即可基于第二预设值，确定哪些UCI被丢弃。在网络设备确定哪一UCI被丢弃的情况下，网络设备不检测“被丢弃的UCI的传输资源”，或者，将“被丢弃的UCI的传输资源”配置给其他终端设备。
