Description

一种上行控制信息的复用方法和设备
本申请要求于2021年03月22日提交中国国家知识产权局、申请号为202110300681.3、发明名称为“一种上行控制信息的复用方法和设备”的中国专利申请的优先权，该在先申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及移动通信技术领域，尤其涉及一种上行控制信息复用的方法和设备。
背景技术
为了避免出现过高的峰均比，终端设备(UE)不支持上行控制/数据信道同时传输。当发生多个上行信道资源在时间上重叠时，需要定义具体的信息复用或者丢弃的传输规则，使UE在同一个时刻仅传输一个上行信道。为避免上行信息损失，当不同UCI类型的PUCCH传输资源存在重叠时，需要对UCI进行复用至一个新的PUCCH，以避免同一个载波在时间上并行传输多个PUCCH。经过UCI组合后，配置给某种UCI类型的PUCCH资源上可能传输多种UCI类型。例如，半静态的SPS-PUCCH-AN-List-r16配置的PUCCH资源可能传输SPS HARQ-ACK和SR，动态的PUCCH-ResourceSet配置的PUCCH资源上可能传输动态调度PDSCH的HARQ-ACK和CSI/SR等。
另一方面，时隙结构灵活可变、PUCCH的资源的时域传输资源占用的OFDM符号位置以及个数是半静态配置的，而当PUCCH的时域资源和下行符号、系统信息块占用的符号等冲突时，PUCCH传输将被取消。根据现有技术，不同UCI类型的PUCCH传输资源存在重叠时，按照预设的规则进行UCI组合，组合后的UCI的类型以及数量对应的PUCCH资源可能与下行符号、系统信息块占用的符号等冲突而被取消，进而造成组合后UCI传输失败，影响系统效率。

图1为本申请方法的实施例流程图；
图2为本申请实施例中的各PUCCH关系示意图；
图3为本发明网络设备的结构示意图；
图4为本发明终端设备的结构示意图。
具体实施方式
本发明的构思是：不同UCI类型的PUCCH传输资源存在重叠时，尽量实现UCI组合传输。根据组合UCI的类型和数量确定用于复用UCI信息的PUCCH资源：如果该PUCCH资源在时间上包括无效符号，则尝试发送组合前的一部分类型的UCI，或者尝试降低至少一种UCI的比特数量，重新确定用于复用UCI信息的PUCCH。
为尝试发送复用前的至少一种UCI，判断每一种UCI各自对应的PUCCH是否包括无效符号；如果UCI组合之前各自的PUCCH均不包括无效符号，则传输优先级较高的UCI的PUCCH，丢弃其它PUCCH；如果其中一个包括无效符号、另一个不包括无效符号，则放弃组合，仅发送不包括无效符号的PUCCH。
为尝试尽可能多地发送UCI，可降低一种UCI的比特数，例如，第一种UCI的比特数是N，第二种UCI的比特数是M，则根据N’比特第一种UCI确定一临时PUCCH，使临时PUCCH和第二UCI对应的PUCCH无重叠地传送；还可以，通过搜索适当的N’值，使N’比特第一UCI和M比特第二UCI组合传送时，所分配的用于复用的PUCCH不包括无效符号。其中的N’可以是使临时PUCCH、用于复用的PUCCH中至少一个包括无效符号的最大值。
在上述构思被实施的基础上，再考虑将N-N’比特第一种UCI延迟到其 它时间单元发送。
另外，作为一种特殊情况，对应当前时隙/子时隙仅有一种UCI的情况，如果该UCI对应的PUCCH包括无效符号，也可以尝试减少该UCI的数量，重新确定UCI，尽量在当前时隙/子时隙发送尽量多的UCI。
以下结合附图，详细说明本申请各实施例提供的技术方案。
本申请实施例提供一种上行控制信息复用方法，包括以下步骤：
步骤101、确定待传送的第一UCI、第二UCI及配置选择的第一PUCCH、第二PUCCH；
在本申请的任意一个实施例中，所述第一UCI、第二UCI分别是以下类型UCI的一种，或者，所述第一UCI、第二UCI分别包含以下类型UCI的至少一种：SPS HARQ-ACK，动态调度的HARQ-ACK，CSI，SR。
在设定的时间单元内，包含N比特第一UCI和M比特第二UCI，其中N>0，M≥0；
在与第一UCI的类型相对应的第一PUCCH配置集合中确定用于传送N比特第一UCI的第一PUCCH；
在与第二UCI的类型相对应的第二PUCCH配置集合中确定用于传送M比特第二UCI的第二PUCCH。
所述第一PUCCH配置集合、第二PUCCH配置集合，例如可以是，如3gpp 38.213 V16.3.0和3gpp 38.331 V16.3.0所定义的，网络设备给UE配置的PUCCH资源，可以是用于SPS HARQ-ACK、CSI、SR或者动态调度HARQ-ACK的PUCCH资源集合。例如，通过高层信令SPS-PUCCH-AN-List-r16或n1PUCCH-AN配置针对SPS HARQ-ACK的PUCCH资源集、通过高层信令multi-CSI-PUCCH-ResourceList配置针对CSI的PUCCH资源集、通过高层信令PUCCH-ResourceSet配置针对动态调度PDSCH的HARQ-ACK的资源集合组，构成所述第一PUCCH配置集合或第二PUCCH配合集合。SPS-PUCCH-AN-List-r16或n1PUCCH-AN、multi-CSI-PUCCH-ResourceList、和PUCCH-ResourceSet各自配置的PUCCH资源集或者PUCCH资源集合组中的PUCCH均是独立配置的，构成第一PUCCH或第二PUCCH。每个PUCCH资源配置的时域传输资源配置包括起始OFDM符号位置以及占用OFDM符号个数等。
在第一PUCCH配置集合中确定第一PUCCH，或者在第二PUCCH配置集合中确定第二PUCCH，是根据第一UCI或第二UCI的比特数量选择的，例如，
SPS-PUCCH-AN-List-r16中每个PUCCH资源分别与预设数量的比特区间对应。例如网络设备通过SPS-PUCCH-AN-List-r16消息给UE配置4个PUCCH资源。其中第1个PUCCH资源对应比特数不大于2的上行控制信息反馈，第二个PUCCH资源对应的上行控制比特区间是(2，N 1，SPS]，第3个PUCCH资源对应的上行控制比特区间是(N 1，SPS，N 2，SPS]，第4个PUCCH资源对应的上行控制比特区间是(N 2，SPS，N 3，SPS]。其中N 1，SPS，N 2，SPS，N 3，SPS分别是预设的值。UE在确定使用SPS-PUCCH-AN-List-r16配置的PUCCH资源时，根据UCI的比特值在哪个区间，相应地确定使用哪个PUCCH资源。同样，multi-CSI-PUCCH-ResourceList配置针对CSI反馈的PUCCH资源集中也包括若干个PUCCH资源，分别与预设数量的比特区间对应。PUCCH-ResourceSet消息则是给UE配置1～4个PUCCH资源集组合。每个PUCCH资源集适用于不同的上行控制信息的比特数范围。UE在确定使用PUCCH-ResourceSet配置的PUCCH资源时，根据UCI的比特值在哪个区间，在该1～4个PUCCH资源组中确定一个PUCCH资源集合，作为反馈HARQ-ACK码本的备用PUCCH集合，然后根据动态调度PDSCH的调度指示信息在备用PUCCH集合中确定一个用作发送这些UCI。
步骤102、根据第一PUCCH和/或第二PUCCH时域冲突，选择第一备用PUCCH，用于传送所述第一UCI和/或第二UCI；
本申请所述的时域冲突，包括第一种时域冲突或第二种时域冲突。
第一种时域冲突是，第一PUCCH和第二PUCCH中存在时域上重叠的符号；第二种时域冲突是，第一PUCCH或第二PUCCH中存在无效符号，所述无效符号，指在所述的时间单元内不能用于传送上行信息的符号。
关于第一种时域冲突，终端设备(UE)不支持上行控制/数据信道同时传输。当发生多个上行信道资源在时间上重叠时，需要定义具体的信息复用或者丢弃的传输规则
关于第二种时域冲突，NR系统支持灵活可变的时隙结构。一个时隙内的符号可能包括三种类型：DL(下行)符号、UL(上行)符号、或者F(Flexible,灵活) 符号。帧结构配置采用半静态RRC配置和动态DCI配置结合的方式。基站通过RRC小区级和UE专用级配置为UE半静态的帧格式。在配置半静态帧格式后，系统可以通过时隙结构指示信息(Slot format indication,SFI)调整帧格式配置。一般地，如果PUCCH所在的时隙被配置为下行时隙，或者PUCCH资源的至少一个符号被配置为下行符号或被系统信息块占用，该PUCCH将被丢弃。如果半静态配置的PUCCH资源和SFI指示的灵活符号重叠，该PUCCH传输也被取消。
当存在所述时域冲突时，确定第一备用PUCCH，目的在于消除所述时域冲突。尤其是，当第一PUCCH和第二PUCCH存在第一种时域冲突时，确定第一备用PUCCH，消除第一种时域冲突。
确定第一备用PUCCH，包含以下步骤：如果M＝0，第一备用PUCCH为第一PUCCH，(或者，如果N＝0，第二备用PUCCH为第二PUCCH)。
如果M>0且N>0，并且第一PUCCH和第二PUCCH之间存在时域重叠的符号，则在所述时间单元内确定用于传送N比特第一UCI和M比特第二UCI的组合信息的第一备用PUCCH。
本步骤中的“组合信息”，是指将N比特第一UCI和M比特第二UCI复用后的信息方式，在第一备用PUCCH中传送。
在第一PUCCH配置集合中确定第一备用PUCCH，或者在第二PUCCH配置集合中确定第一备用PUCCH，是根据第一UCI和第二UCI的总比特数量N+M选择的，每个PUCCH资源分别与预设数量的比特区间对应，因而根据第一UCI和第二UCI的总比特数量N+M所对应的第一备用PUCCH是确定的。
步骤103、确定第一备用PUCCH是否存在时域冲突，在不包含无效符号的第一备用PUCCH传送第一UCI和第二UCI的组合信息；
如果所述第一备用PUCCH不包含无效符号，则在所述第一备用PUCCH中传送N比特第一UCI和M比特第二UCI的组合信息；
步骤104、在所述第一备用PUCCH中包含无效符号时，确定第二备用PUCCH，用于传送N’比特第一UCI和/或M’比特第二UCI的组合信息。
当存在所述时域冲突时，确定第二备用PUCCH，目的在于消除所述时域冲突。尤其是，当第一备用PUCCH中存在第二种时域冲突时，减少第一UCI和/或第二UCI的比特数量，确定第二备用PUCCH，消除第二种时域冲突。
在所述时间单元内确定第二备用PUCCH，在第二备用PUCCH中发送N’比特第一UCI信息、M’比特第二UCI信息或N’比特第一UCI+M’比特第二UCI的组合信息；其中，N’≤N，M’≤M，且N’+M’<N+M；
本步骤中的“组合信息”，是指将N’比特第一UCI和M’比特第二UCI复用后的信息方式，在第二备用PUCCH中传送。
在第一PUCCH配置集合中确定第二备用PUCCH，或者在第二PUCCH配置集合中确定第二备用PUCCH，是根据减少后的第一UCI和第二UCI的总比特数量N’+M’选择的。由于每个PUCCH资源分别与预设数量的比特区间对应，因而根据第一UCI和第二UCI的总比特数量N’+M’所对应的第二备用PUCCH是确定的。
具体包含以下技术方案，确定第二备用PUCCH的结果，包含步骤104A～F中的任意一个：
步骤104A、所述第一PUCCH和所述第二PUCCH均不包含无效符号，选择高优先级UCI所在PUCCH；
如果所述第一UCI的优先级高于所述第二UCI，则确定所述第二备用PUCCH为所述第一PUCCH，令N’＝N，M’＝0；
如果所述第二UCI的优先级高于所述第一UCI，则确定所述第二备用PUCCH为所述第二PUCCU，令N’＝0，M’＝M。
步骤104B、所述第一PUCCH或所述第二PUCCH中包含无效符号，选择不包含无效符号的PUCCH；
如果所述第二PUCCH包含无效符号、所述第一PUCCH不包含无效符号，则确定所述第二备用PUCCH为所述第一PUCCH，令N’＝N，M’＝0；
如果所述第一PUCCH包含无效符号、所述第二PUCCH不包含无效符号，则确定所述第二备用PUCCH为所述第二PUCCH，令N’＝0，M’＝M。
步骤104C、减少第一UCI或第二UCI的比特数量重新确定第二备用PUCCH，用于传送减少比特数量后的第一UCI和第二UCI的组合信息；
令M’＝M，在所述时间单元内确定(特殊情况下，M＝0，在与第一UCI的类型相对应的第一PUCCH配置集合中)用于传送N’比特第一UCI和M’比特第二UCI的第二备用PUCCH，其中N’是使所述第二备用PUCCH不包含无效符号的最大值，且N<N’；
或者，
令N’＝N，在所述时间单元内(特殊情况下，N＝0，在与第二UCI的类型相对应的第二PUCCH配置集合中)确定用于传送N’比特第一UCI和M’比特第二UCI的第二备用PUCCH，其中M’是使所述第二备用PUCCH不包含无效符号的最大值，且M<M’。
步骤104D、减少第一UCI和第二UCI的比特数量重新确定第二备用PUCCH，用于传送减少比特数量后的第一UCI和第二UCI的组合信息；
在第一PUCCH配置集合或第二PUCCH配置集合中确定用于传送N’比特第一UCI和M’比特第二UCI组合信息的第二备用PUCCH，其中，N’+M’是使所述第二备用PUCCH不包含无效符号的最大值。
步骤104E、减少第一UCI和第二UCI的比特数量，并且包含至少一种UCI中不支持延迟发送的比特数。

或者，
令N’＝N 1、M’≤M，在所述时间单元内确定用于传送N’比特第一UCI和M’比特第二UCI的组合信息的第二备用PUCCH，其中N 1<N，N 1是所述N比特第一UCI中不支持延迟发送的比特数，M’是使所述第二备用PUCCH不包含无效符号的最大值。
步骤104F、减少第一UCI或第二UCI数量重新确定第二备用PUCCH，用于传送第一UCI或第二UCI；

或者，
令N’＝0，在与第二UCI的类型相对应的第二PUCCH配置集合中确定用 于传送M’比特第二UCI的第二PUCCH，其中M’是使所述第二PUCCH不包含无效符号的最大值，其中M’<M，再以所述第二PUCCH作为第二备用PUCCH；此实施例尤其适用于第二备用PUCCH和所述第一PUCCH之间没有时域重叠的符号，因此，第一PUCCH仍能够携带N比特第一UCI传送。
步骤105、在步骤104的基础上，在延迟的时间单元发送剩余的N-N’比特第一UCI和/或M-M’比特第二UCI。

在第一PUCCH配置集合中确定N比特第一UCI对应的第一PUCCH，所述第一PUCCH配置集合与第一UCI对应；在第二PUCCH配置集合中确定M比特第二UCI对应的第二PUCCH，所述第二PUCCH配置集合与第二UCI对应。
所述第一PUCCH和第二PUCCH之间至少有一个重叠的符号，为实现二者复用传送，在第一PUCCH配置集合或第二PUCCH配置集合中确定N+M比特UCI对应的第一备用PUCCH。
例如，不同UCI类型的组合传输规则包括如下：
当第一UCI是承载动态调度PDSCH的HARQ-ACK时，第一PUCCH配置集合为PUCCH-ResourceSet信令配置的PUCCH资源集合；根据第一UCI和重叠信道中其它UCI的比特数之和，在第一PUCCH配置集合中确定备用的PUCCH集合，然后根据动态调度PDSCH的调度指示信息在备用PUCCH集合中确定一个，作为第一备用PUCCH，用作发送这些UCI的PUCCH。
当第一UCI中不包含动态调度PDSCH的HARQ-ACK，但包含CSI时，第一PUCCH配置集合为multi-CSI-PUCCH-ResourceList信令配置的PUCCH资源集合；根据第一UCI和重叠信道中其它UCI的比特数之和，在第一PUCCH配置集合中确定第一备用PUCCH，用作发送这些UCI的PUCCH。
当第一UCI中不包含动态调度PDSCH的HARQ-ACK，也不包含CSI，但包含SPS PDSCH的HARQ-ACK时，第一PUCCH配置集合为 SPS-PUCCH-AN-List-r16信令配置的PUCCH资源集合；根据第一UCI和重叠信道中其它UCI的比特数之和，在第一PUCCH配置集合中确定第一备用PUCCH，用作发送这些UCI的PUCCH。
如果所述第一备用PUCCH不包括无效符号，在所述第一备用PUCCH发送所述N比特第一UCI和M比特第二UCI。
如果所述第一备用PUCCH包括无效符号，在所述设定的时间单元内确定第二备用PUCCH，在所述第二备用PUCCH发送N比特第一UCI或M比特第二UCI，所述第二备用PUCCH不包括无效符号。
如图2举例，设定的时间单元包括14个符号，时隙结构配置为“DDDDFFUUUUUUUU”，其中“D”代表下行符号、“F”代表灵活符号、“U”代表上行符号。在设定的时间单元内，通过高层信令SPS-PUCCH-AN-List-r16配置的针对SPS HARQ-ACK的PUCCH资源集(第一PUCCH配置集合)包括PUCCH-A、PUCCH-B、PUCCH-C和PUCCH-D，通过高层信令multi-CSI-PUCCH-ResourceList配置针对CSI的PUCCH资源集(第二PUCCH配置集合)为PUCCH-E、PUCCH-F、PUCCH-G和PUCCH-H。假设设定的时间单元包括有N比特SPS HARQ-ACK和M比特CSI待传输。N比特SPS HARQ-ACK与SPS-PUCCH-AN-List-r16配置的PUCCH-A对应，为第一UCI；M比特CSI与multi-CSI-PUCCH-ResourceList配置的PUCCH-F对应，为第二UCI。由于PUCCH-A(第一PUCCH)和PUCCH-F(第二PUCCH)在时间上有重叠的符号，将N比特SPS HARQ-ACK和M比特CSI组合，在multi-CSI-PUCCH-ResourceList中确定与N+M比特组合UCI对应的PUCCH-B(第一备用PUCCH)。
PUCCH-B中包括无效符号(下行符号和SFI指示的灵活符号)，按照现有技术，PUCCH-B会被丢弃。同时，N比特SPS HARQ-ACK和M比特CSI也随之丢弃。
采用本发明方案，如果第一备用PUCCH不包括无效符号，则在第一备用PUCCH发送组合UCI，即N比特SPS HARQ-ACK和M比特CSI；如果第一备用PUCCH包括无效符号，则在设定的时间单元内确定第二备用PUCCH，尽量在第二备用PUCCH上发送N比特SPS HARQ-ACK和/或N比特CSI中的至少一部分，降低UCI不能正常发送对系统效率的影响。确定第二备用 PUCCH以及在第二备用PUCCH上发送N比特SPS HARQ-ACK和/或M比特CSI中的一部分方式包括：
方式一、
如步骤104A，如果第一PUCCH和第二PUCCH均不包括无效符号，则第二备用PUCCH为第一UCI和第二UCI中优先级高的对应的PUCCH。可以在第一PUCCH和第二PUCCH之间发送优先级较高的第一UCI，降低组合UCI不能正常发送对系统效率的影响。例如，
如果第一UCI的优先级高于第二UCI，第二备用PUCCH为第一PUCCH，在第二备用PUCCH发送所述N比特第一UCI，并丢弃M比特第二UCI。也就是说，令N’＝N，M’＝0。
如果第二UCI的优先级高于第一UCI，第二备用PUCCH为第二PUCCH，在第二备用PUCCH发送M比特第二UCI，并丢弃N比特第一UCI。也就是说，令N’＝0，M’＝M。
如图2举例，如果第一UCI是SPS HARQ-ACK，N比特第一UCI对应配置给SPS HARQ-ACK的PUCCH-C(第一PUCCH)；第二UCI是CSI，M比特第二UCI对应配置给CSI的PUCCH-E(第二PUCCH)，N比特第一UCI和M比特第二UCI的组合对应配置给SPS HARQ-ACK的PUCCH-F(第一备用PUCCH)。由于PUCCH-F包括无效符号，不能传输。PUCCH-C和PUCCH-E均不包括无效符号，由于SPS HARQ-ACK的优先级高于CSI，则在PUCCH-C(以第一PUCCH作为第二备用PUCCH)发送N比特SPS HARQ-ACK，并丢弃M比特CSI。由此，降低了组合UCI不能正常发送对系统效率的影响。
方式二、
如步骤104B，如果第一PUCCH不包括无效符号而第二PUCCH包括无效符号，则第二备用PUCCH为第一PUCCH，在第二备用PUCCH发送N比特第一UCI，并丢弃M比特第二UCI；如果第二PUCCH不包括无效符号而第一PUCCH包括无效符号，则第二备用PUCCH为第二PUCCH，在第二备用PUCCH发送M比特第二UCI，并丢弃N比特第一UCI。
如图2所示，如果N比特SPS HARQ-ACK(第一UCI)与SPS-PUCCH-AN-List-r16配置的PUCCH-A(第一PUCCH)对应，M比特CSI(第二UCI)与multi-CSI-PUCCH-ResourceList配置的PUCCH-F(第二PUCCH) 对应时，由于PUCCH-A和PUCCH-F在时间上有重叠的符号，将N比特SPS HARQ-ACK和M比特CSI组合，在multi-CSI-PUCCH-ResourceList中确定与N+M比特组合UCI对应的是PUCCH-B(第一备用PUCCH)。PUCCH-B中包括无效符号。
按照现有技术，PUCCH-B被丢弃。同时，N比特SPS HARQ-ACK和M比特CSI也随之丢弃。
采用本实施例方案，PUCCH-A包括无效符号，PUCCH-E不包括无效符号，则在PUCCH-E(以第二PUCCH作为第二备用PUCCH)发送M比特CSI，并丢弃N比特SPS HARQ-ACK。由此，降低了组合UCI不能正常发送对系统效率的影响。
方式三、
在N比特第一UCI中取前N’比特(或者后N’比特)，第二备用PUCCH是备选PUCCH组中任一个不含有无效符号的PUCCH。备选PUCCH组由以下方式生成：
确定N’比特第一UCI在第一PUCCH配置集合中对应的PUCCH为第一临时PUCCH，如果第一临时PUCCH与第二PUCCH在时间上没有重叠，第一临时PUCCH与第二PUCCH属于备选PUCCH组。
如步骤104F，如果第一临时PUCCH中不含有无效符号，对应第二备用PUCCH可以是第一临时PUCCH，在第二备用PUCCH发送N’比特第一UCI。此时，还可以第二PUCCH传送M比特第二UCI。
如果第二PUCCH中不含有无效符号，对应第二备用PUCCH还可以是第二PUCCH，在第二备用PUCCH发送M比特第二UCI。此时，还可以通过第一临时PUCCH发送N’比特第一UCI。
如果第一临时PUCCH仍然与第二PUCCH在时间上有重叠，如步骤104C或步骤104E，则在所述设定的时间单元内确定与N’+M比特第一UCI和第二UCI组合对应的第二临时PUCCH，第二临时PUCCH属于备选PUCCH组。
如果第二临时PUCCH中不含有无效符号，对应第二备用PUCCH是第二临时PUCCH，在第二备用PUCCH发送N’比特第一UCI和M比特第二UCI的组合，其中N’<N、M’＝M。
如图2所示，假设N比特SPS HARQ-ACK(第一UCI)与 SPS-PUCCH-AN-List-r16配置的PUCCH-A(第一PUCCH)对应，M比特CSI(第二UCI)与multi-CSI-PUCCH-ResourceList配置的PUCCH-F(第二PUCCH)对应时，由于PUCCH-A和PUCCH-F在时间有重叠的符号，将N比特SPS HARQ-ACK和M比特CSI组合，在multi-CSI-PUCCH-ResourceList中确定与N+M比特组合UCI对应的是PUCCH-B(第一备用PUCCH)。PUCCH-B中包括无效符号。
按照现有技术，PUCCH-B被丢弃。同时，N比特SPS HARQ-ACK和M比特CSI也随之丢弃。
采用本实施例方案，N’比特SPS HARQ-ACK与SPS-PUCCH-AN-List-r16配置的PUCCH-C(第一临时PUCCH)对应，PUCCH-C与PUCCH-F有重叠的符号，在multi-CSI-PUCCH-ResourceList中确定与N’+M比特组合UCI对应的是PUCCH-G(第二临时PUCCH作为第二备用PUCCH)，且PUCCH-G不包括无效符号，则在PUCCH-G发送N’比特SPS HARQ-ACK和M比特CSI。由此，降低了组合UCI不能正常发送对系统效率的影响。
需要说明的是，从N’的取值N-1开始从大到小确定备选PUCCH组，第二备用PUCCH是备选PUCCH组不为空的最大的N’值对应的备选PUCCH组中的信道。
可选的，在N比特第一UCI中取前N’比特(或者后N’比特)确定第二备用PUCCH之前，需要确定配置允许第一UCI延迟发送，或者，确定配置允许N-N’比特第一UCI延迟发送。以第一UCI是SPS HARQ-ACK为例，为支持系统有多个周期和紧急度优先的数据流，支持为UE配置多套SPS参数并且SPS配置的周期可能很短。如果用于反馈SPS HARQ-ACK的PUCCH包括无效符号，该PUCCH将被取消。为避免SPS配置的周期很短的情况下HARQ-ACK反馈频繁被取消，系统可支持为每个SPS配置是否允许延迟发送SPS HARQ-ACK。在本实施例中，N’比特第一UCI在第二备用PUCCH发送，该N’比特第一UCI可包括允许延迟发送的SPS HARQ-ACK。按照现有技术，由于第一备用PUCCH包括无效符号，N比特第一UCI和M比特第二UCI全部被丢弃，相应地，N比特第一UCI中允许延迟的UCI将在设定的时间单元之后的时间单元发送，UCI的时延特性较差，影响系统效率。使用本实施例方案，N’比特第一UCI中允许延迟的UCI可以在设定的时间单元发送，较之 现有技术改进了UCI的时延特性，提高了系统效率。
实施例2
设定的时间单元包括N比特第一UCI和M比特第二UCI，N>0，M＝0；
如步骤104C，在第一PUCCH配置集合中确定N比特第一UCI对应的第一PUCCH，所述第一PUCCH配置集合与第一UCI对应；由于此时N+M＝N，在所述第一PUCCH配置集合中确定的第一备用PUCCH即为第一PUCCH.
如果第一备用PUCCH不包括无效符号，在第一备用PUCCH发送所述N比特第一UCI；
如果第一备用PUCCH包括无效符号，在设定的时间单元内确定第二备用PUCCH，在第二备用PUCCH发送N’比特第一UCI，其中N’<N。
如图2举例，设定的时间单元包括14个符号，时隙结构配置为“DDDDFFUUUUUUUU”，其中“D”代表下行符号、“F”代表灵活符号、“U”代表上行符号。在所述设定的时间单元内，通过高层信令SPS-PUCCH-AN-List-r16配置的针对SPS HARQ-ACK(第一UCI)的PUCCH资源集(即第一PUCCH配置集合)包括PUCCH-A、PUCCH-B、PUCCH-C和PUCCH-D，通过高层信令multi-CSI-PUCCH-ResourceList配置针对CSI(第二UCI)的PUCCH资源集(即第二PUCCH配置集合)包括PUCCH-E、PUCCH-F、PUCCH-G和PUCCH-H。假设设定的时间单元包括有N比特SPS HARQ-ACK，并且没有其它UCI待传输。N比特SPS HARQ-ACK与SPS-PUCCH-AN-List-r16配置的PUCCH-A(第一PUCCH)对应。
假如PUCCH-A包括无效符号(下行符号和SFI指示的灵活符号)，按照现有技术，PUCCH-A被丢弃。同时，N比特SPS HARQ-ACK也随之丢弃。
采用本发明方案，如果第一备用PUCCH包括无效符号，则在设定的时间单元内确定第二备用PUCCH，尽量在第二备用PUCCH上发送N比特SPS HARQ-ACK和M比特CSI中的一部分，降低UCI不能正常发送对系统效率的影响。确定第二备用PUCCH的方法如下：
在N比特第一UCI中取前N’比特(或者后N’比特)，确定N’比特第一UCI在第一PUCCH配置集合中对应的PUCCH为第二备用PUCCH。在第二备用PUCCH上发送N’比特。
在本实施例中，在N比特第一UCI中取N′比特。N′比特第一UCI对应 SPS-PUCCH-AN-List-r16配置的另一PUCCH，例如对应PUCCH-D(再次确定第一PUCCH，作为第二备用PUCCH)。由于PUCCH-D不包括无效符号，N’比特第一UCI可以在PUCCH-D传输。在本时隙发送N比特第一UCI的一部分，可降低UCI不能正常发送对系统效率的影响。
为了尽可能多地降低现有技术中UCI不能正常发送对系统效率的影响N’是使第二备用PUCCH不包括无效符号的最大值。调整N’的值改变所选取的第一PUCCH或第二备用PUCCH，这是由于SPS-PUCCH-AN-List-r16中每个PUCCH资源分别与预设数量的比特区间对应。通过从N’取值大到小尝试在SPS-PUCCH-AN-List-r16中确定第二备用PUCCH，可在设定的时间单元发送尽量多的第一UCI，尽大可能降低UCI不能正常发送对系统效率的影响。
预设N’比特第一UCI是取N比特第一UCI中在前或者在后的比特，以及预设N’是使第二备用PUCCH不包括无效符号的最大值，终端设备和网络设备在设定的时间单元中发送上行控制信息的第二备用PUCCH将有相同的确定结果，满足UCI的传输需求。
可选的，在N比特第一UCI中取前N’比特(或者后N’比特)确定第二备用PUCCH之前，需要确定配置允许第一UCI延迟发送，或者，确定配置允许N-N’比特第一UCI延迟发送。以第一UCI是SPS HARQ-ACK为例，为支持系统有多个周期和紧急度优先的数据流，支持为UE配置多套SPS参数并且SPS配置的周期可能很短。如果用于反馈SPS HARQ-ACK的PUCCH包括无效符号，该PUCCH将被取消。为避免SPS配置的周期很短的情况下，HARQ-ACK反馈频繁被取消，系统可支持为每个SPS配置是否允许延迟发送SPS HARQ-ACK。在本实施例中，N’比特第一UCI在第二备用PUCCH发送，该N’比特第一UCI可包括允许延迟发送的SPS HARQ-ACK。按照现有技术，由于第一备用PUCCH包括无效符号，N比特第一UCI中允许延迟的UCI将在设定的时间单元之后的时间单元发送，UCI的时延特性较差，影响系统效率。使用本实施例方案，N′比特第一UCI中允许延迟的UCI可以在设定的时间单元发送，较之现有技术改进了UCI的时延特性，提高了系统效率。
