Description

物理上行信道的时隙确定方法及装置
本申请要求在2018年04月11日提交中国专利局、申请号为201810321437.3的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本公开涉及通信领域，例如涉及一种物理上行信道的时隙确定方法及装置。
背景技术
在新一代无线通信(New Rat，NR)***中，目前有5种物理上行控制信道(Physical Uplink Control Channel，PUCCH)，分别记为PUCCH格式0～4。
PUCCH格式0的正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号(下文的使用符号进行描述)为1～2个，用于承载1～2比特(bit)的混合自动重传请求-确认(Hybrid Automatic Repeat request-ACKnowledge，HARQ-ACK)，且支持不同终端(User Equipment，UE)之间复用。
PUCCH格式1用于承载1～2bit的HARQ-ACK信息，包含的OFDM符号数大于等于4个，且支持不同UE之间复用。
PUCCH格式2用于传输大于2bit的上行控制信息(Uplink Control Information，UCI)信息(这个UCI可以是HARQ-ACK、调度请求(Scheduling Request，SR)、信道状态信息(Channel State Information，CSI)中的一个或多个)，符号数为1～2个，且不支持不同UE之间复用。
PUCCH格式3用于传输大于2bit的UCI信息，符号数为大于等于4个，且不支持不同UE之间复用。
PUCCH格式4用于传输大于2bit的UCI信息，符号数为大于等于4个，且支持不同UE之间复用。
这里也可以按照PUCCH的符号数范围将它们划分为不同的PUCCH类型，例如格式0和格式2的符号数为1～2个，属于同一PUCCH类型，也可称短格式；格式1，3和4的符号数为大于等于4个，属于同一PUCCH类型，也可称长格式。
相关技术中，UE只能选择一个SR进行发送。即如果多个SR中有多个SR请求时，UE只能发送其中一个SR给基站。那么UE如何将HARQ-ACK和选择 的SR发送给基站呢？基站又怎么知道UE反馈了哪个SR请求呢？
针对相关技术中缺乏确定传输物理上行信道的时隙(slot)的方案的情况，目前还没有有效的解决方案。

在一实施例中，上述步骤的执行主体可以为基站、终端等，但不限于此。
在一实施例中，步骤S102和步骤S104的执行顺序是可以互换的，即可以先执行步骤S104，然后再执行S102。
在一实施例中，在该物理上行信道为物理上行控制信道PUCCH时，该配置信息中包括以下至少之一：PUCCH的起始时隙；起始时隙中该PUCCH的起始正交频分复用OFDM符号位置；起始时隙中该PUCCH持续OFDM符号数量；该PUCCH的m的取值；在该物理上行信道为物理上行共享信道PUSCH时，该配置信息中包括以下至少之一：PUSCH的起始时隙；起始时隙中该PUSCH的起始正交频分复用OFDM符号位置；起始时隙中该PUSCH持续OFDM符号数量；该PUSCH的m的取值。

在一实施例中，当该物理上行信道为PUCCH时，该第二通信节点确定该m个时隙的方式，包括：该PUCCH的起始时隙通过该配置信息确定；后续m-1个时隙需要满足下述条件：时隙中有与该PUCCH在起始时隙中相同的起始OFDM符号位置能被使用；时隙中有允许该PUCCH使用的持续的OFDM符号数大于等于该起始时隙中该PUCCH使用的持续的OFDM符号数；时隙中传输该PUCCH时，该时隙中传输的全部或部分物理上行信道之间不存在时域重叠。需要补充的是，第二通信节点选择出的后续m-1个时隙一般情况下不是连续的m-1个时隙。
在一实施例中，当该物理上行信道为PUSCH时，确定该m个时隙，包括：该PUSCH的起始时隙通过该配置信息确定；后续m-1个时隙需要满足下述条件至少之一：时隙中有与该PUSCH在起始时隙中相同的起始OFDM符号位置能 被使用；时隙中允许该PUSCH使用的持续的OFDM符号数大于等于该起始时隙中该PUSCH使用的持续的OFDM符号数；时隙中传输该PUSCH时，该时隙中传输的全部或部分物理上行信道之间不存在时域重叠；时隙中有与该PUSCH在起始时隙中相同的物理资源块(Physical Resource Block，PRB)能被使用。

依据该配置信息确定该物理上行信道的起始时隙；
确定该起始时隙之后连续m-1个时隙，和该起始时隙共为该m个时隙。
根据本公开的另一个实施例，还提供了一种传输物理上行信道的方法，包括以下步骤一和步骤二。
在步骤一中，第二通信节点接收第一通信节点的第二配置信息，其中，该第二配置信息用于指示该第二通信节点跨W个时隙重复传输物理上行控制信道，其中，在该W个时隙中的一个或多个时隙中，该重复传输的物理上行信道，分别与Q个调度请求SR的物理上行信道出现时域重叠。

需要补充的是，Q个SR可以理解为Q个通道，或Q个PUCCH。本申请文件中的，将X比特在物理上行控制信道中传输，可以是，将X比特的编码后的信息在物理上行控制信道中传输。本申请文件中的，且将该X比特速率匹配在该物理上行控制信道中的信息中进行传输，可以是，将X比特的编码后的信息速率匹配到该物理上行控制信道中的UCI比特的编码后的信息中进行传输。
通过上述技术方案，克服了相关技术中第一通信节点无法知晓第二通信节 点反馈了哪个SR请求的缺陷，实现了向第一通信节点指示多个SR请求的情况。
在一实施例中，该方法还包括以下至少之一：

在一实施例中，该方法还包括：在该W个时隙中，从第一个出现该时域重 叠的时隙开始，以及后续的时隙中，将该X比特在该物理上行控制信道中传输。需要补充的是，此处的后续的时隙可以是，后续的所有W个时隙中的时隙。
根据本公开的另一个实施例，还提供了一种传输物理上行信道的方法，该方法包括以下步骤一和步骤二。
在步骤一中，第二通信节点确定待传输的物理上行控制信道PUCCH和物理上行共享信道PUSCH发生时域重叠。
在步骤二中，该第二通信节点将该PUCCH或该PUCCH中承载的上行控制信息UCI，在该PUSCH中发生时域重叠的符号上传输；
或者，该第二通信节点将该PUCCH或该PUCCH中承载的上行控制信息UCI，在发生时域重叠的符号上传输，且发生时域重叠的符号中的PUSCH被打孔。
需要补充的是，上述UCI可以包括HARQ-ACK，SR，信道状态信息CSI的一者或多者。发生时域重叠位置可以不传输PUSCH。
采用上述技术方案，克服了相关技术中缺乏在PUCCH和PUSCH存在时域重叠时，如何传输物理上行信道方案的缺陷。实现了UCI信息在二者时域重叠位置上传输。
在一实施例中，该第二通信节点将该PUCCH承载的上行控制信息UCI，在该PUSCH中发生时域重叠的符号上传输，包括：该第二通信节点确定用于解码该UCI信息的参考信号RS；将该参考信号RS和该UCI，均在该PUSCH中发生时域重叠的符号上传输。
在一实施例中，在离该时域重叠的OFDM符号最近的两侧或单侧的OFDM符号中，发送PUSCH的DMRS或PUCCH的DMRS。
在一实施例中，该第二通信节点在发生时域重叠的一个或多个时隙中，依据以下方式之一传输该PUCCH或该UCI：
将该UCI或该PUCCH在该物理上行共享信道中传输，且将该物理上行共享信道中的信息进行打孔，在打孔位置中传输该UCI的编码后信息；
将该UCI或该PUCCH在该物理上行共享信道中传输，且将该UCI的编码后信息速率匹配在该物理上行共享信道中的信息中进行传输；
将该UCI或该PUCCH在该物理上行共享信道中传输，且在该物理上行共享信道中预留资源，在预留资源中传输该UCI的编码后信息。
下面结合本公开示例性实施例进行详细说明。
在NR***中，物理上行控制信道PUCCH格式0用于承载1～2bit的HARQ-ACK，并通过配置的循环序列CS表示HARQ-ACK是ACK或NACK；如果同时有调度请求传输，那么也是需要配置对应的CS来表示。
相关技术中的PUCCH格式0的HARQ-ACK的传输，以及PUCCH格式0的HARQ-ACK和SR请求同时传输的做法：
如果有SR和HARQ-ACK同传，则使用HARQ-ACK的时频资源，且通过约定序列表达HARQ-ACK和SR。例如表1是根据相关技术中1bit HARQ-ACK和CS分配表，表2是根据相关技术中的2bit HARQ-ACK和CS分配表。表3是根据相关技术中1bit HARQ-ACK与SR同传的CS分配表，表4是根据相关技术中2bit HARQ-ACK与SR同传的CS分配表。其中，一个基序列包含12个CS。
表1
HARQ-ACK值 0 1
循环序列CS m CS＝0 m CS＝6
表2
HARQ-ACK值 {0,0} {0,1} {1,1} {1,0}
CS m CS＝0 m CS＝3 m CS＝6 m CS＝9
表3
HARQ-ACK值 0 1
CS m CS＝3 m CS＝9
表4
HARQ-ACK值 {0,0} {0,1} {1,1} {1,0}
CS m CS＝1 m CS＝4 m CS＝7 m CS＝10
相关技术中PUCCH格式1的HARQ-ACK的传输，以及PUCCH格式1的HARQ-ACK和有SR请求的同时传输的做法：
如果有SR+HARQ-ACK同传，则使用SR的时频资源，且使用分配给SR 的CS，HARQ-ACK调制到SR的CS上；如果没有SR请求，HARQ-ACK使用HARQ-ACK的时频资源，且CS使用分配给HARQ-ACK的CS，HARQ-ACK调制到SR的CS上。总结为：通过使用的时频资源来表达SR的“有”和“无”，且CS与时频资源绑定，HARQ-ACK调制到传输的CS。
相关技术中，对于SR的PUCCH允许使用PUCCH格式0和PUCCH格式1，其中PUCCH格式1按照相关技术的协议规定允许跨时隙传输。那么，当一个UE的一个承载HARQ-ACK的物理上行控制信道PUCCH格式0或格式1与多个承载调度请求SR的PUCCH时域重叠时且其中所述HARQ-ACK的PUCCH或SR的PUCCH是跨时隙的，例如，承载HARQ-ACK的PUCCH是格式1跨2个时隙，承载SR的多个PUCCH也是格式1跨2个时隙，且时域重叠或部分重叠。相关技术中，UE只能选择一个SR进行发送。即如果多个SR中有多个SR请求时，UE只能发送其中一个SR给基站。那么UE如何将HARQ-ACK和选择的SR发送给基站呢？基站又怎么知道UE反馈了哪个SR请求呢？
针对上述问题，本公开涉及一种物理上行控制信道与多个调度请求SR的信道时域重叠时，上行控制信道中的HARQ-ACK和SR的传输。
应用实施例1
一个UE的承载HARQ-ACK的PUCCH格式1，3或4是跨多个时隙模式的，和该UE的多个SR的PUCCH时域重叠。多个SR的PUCCH也可能是跨多个时隙，也可以能不是跨多个时隙的。时域重叠可以是它们的OFDM符号完全重叠或部分重叠。基站和UE约定采用下面方式传输HARQ-ACK和SR。
基站和UE约定：
在相关选择后续时隙的条件中，再增加：UE承载HARQ-ACK的PUCCH在选择后续时隙(除第一个时隙外)时，如果该时隙中有该UE的SR的PUCCH，且如果选择了该时隙后，会出现承载HARQ-ACK和SR的PUCCH出现时域重叠时，UE不选择该时隙作为承载HARQ-ACK的PUCCH的时隙。
或者描述为：在相关选择后续时隙的条件中，再增加：UE承载HARQ-ACK的PUCCH在选择后续时隙(除第一个时隙外)时，选择UE的SR的PUCCH和该PUCCH不会出现时域重叠的时隙。
例如可以描述为：
UE被配置了跨m个(m大于1)时隙重复的PUCCH，UE根据配置的PUCCH的起始时隙、起始时隙中的起始符号位置、持续符号数量和要求重复的时隙数 量m，再结合是否会发生多个上行物理信道时域重叠，来确定后续那些时隙被选择发送该PUCCH。
规则约定包括：UE在被提供了时隙类型的配置信息时，UE从起始时隙开始选择后续的m-1个时隙(或者说从起始时隙开始选择m个时隙，包括起始时隙在内)中有足够PUCCH使用的上行OFDM符号，如有大于或等于起始时隙中PUCCH使用的符号数，其次可选的增加条件是且有与起始时隙中PUCCH相同的起始符号，且该时隙中如果承载PUCCH时，不会引起UE的多个上行物理信道(包括承载不同UCI信息的PUCCH、PUSCH等)时域重叠。
如果UE在未被提供时隙类型的配置信息时，UE被配置跨m个时隙重复PUCCH时，UE认为从基站配置的起始时隙开始后续的m-1个时隙为PUCCH重复的时隙，或者描述为UE认为基站配置的起始时隙开始共连续m个时隙为PUCCH重复的时隙。这种情况下，基站需要保证后续的时隙满足上述为UE提供了时隙类型的配置信息时选择时隙的条件。
例如，UE的PUCCH被配置跨4个时隙重复，且基站配置了PUCCH的第一个时隙以及在该时隙中PUCCH时域的起始OFDM符号(文中符号均指OFDM符号)和符号数，配置了PUCCH起始PRB，如果PUCCH跳频，则为每个跳频配置对应的起始PRB。然后UE在选择后续时隙时，如果发现时隙中有PUCCH可以使用的OFDM符号，且PUCCH能够使用的符号能与第一个时隙中的PUCCH的起始OFDM符号以及符号数相同，且不会导致PUCCH和该UE的SR的PUCCH时域重叠时，UE选择该时隙作为PUCCH后续时隙。
当然，这里的SR的PUCCH也可以是该UE的其他目的的PUCCH或PUSCH，例如传输CSI的PUCCH，或者是UE的PUSCH。这样的限制主要为了避免UE在一个时隙中出现多个上行物理信道，且这些上行物理信道存在时域重叠，这样将导致UE的PUCCH在多个时隙之间不能合并解码，或者导致UE同时传输多个上行物理信道将导致UE实现成本显著增加。因为按照相关技术，对于一个UE当多个上行物理信道出现时域重叠(例如按照OFDM符号时域重叠，包括完全重叠和部分重叠)，UE将传输一个上行物理信道，以降低UE实现成本。
如果UE未被提供时隙类型的配置信息，那么UE认为PUCCH后续的时隙和第一个时隙是连续的。这种情况下，基站不配置UE关于时隙类型的配置信息，基站为UE配置了跨时隙的PUCCH时，基站保证从第一个时隙开始，后续的连 续的要求数量的时隙是满足第一个时隙中发送PUCCH的条件。所以，这种情况下，UE认为PUCCH跨时隙时，PUCCH的第一个时隙之后，后续的时隙会有连续的要求数量的且满足传输PUCCH要求(和第一个时隙中传输PUCCH一样)的时隙。也就是说UE被提供了时隙类型配置信息，按照上述的判断条件进行处理。
上述的方式也能被使用为PUSCH通过多个时隙重复发送的情况，原理是类似的。只需要对于上述的PUCCH进行对等替换即可。这里不再赘述。例如，UE的PUSCH被配置跨n个(n大于1)时隙重复，且基站配置了PUSCH的第一个时隙位置以及在该时隙中PUSCH使用的起始符号和符号数(也配置了PUSCH的PRB)。然后UE在选择后续时隙时，如果发现时隙中有PUSCH可以使用的OFDM符号，且PUSCH能够使用的符号能与第一个时隙中的PUSCH的起始符号以及符号数相同，且不会导致PUSCH和该UE的其他的上行物理信道(例如PUCCH或另一个PUSCH等)时域重叠(这一条对于PUSCH选择后续时隙作为可选的条件)时，UE选择该时隙作为PUSCH后续时隙。对于PUSCH取消最后一个条件的限制，主要是因为PUSCH即使被速率匹配或打孔后，PUSCH仍然能够和其他时隙中的PUSCH合并解码，但是性能会略有降低，所以最后一个条件作为可选项的。对于UE的PUSCH，如果跨时隙传输，UE未被提供时隙类型的配置信息时，UE默认从第一个时隙开始，后续连续n-1的时隙都是满足要求的时隙。也就是说UE被提供了时隙类型配置信息，按照上述的判断条件进行处理。
应用实施例2
相关技术中，对于在一个时隙中传输的PUCCH格式2，3和4，当与K(K大于0)个SR的PUCCH时域重叠时，将在PUCCH承载的UCI末尾增加X比特，
Figure PCTCN2019082161-appb-000005
X描述第几个SR发送了SR请求。如果K个SR均为无SR请求，那么X bit取值为均为0。
本文通过分析相关技术，发现下面的问题。
当一个UE被配置跨多个时隙重复传输PUCCH格式3或4(这里可以泛指需要跨时隙重复传输的物理信道)，且在传输PUCCH的一个或多个时隙中出现了，与UE的一个或多个SR的PUCCH时域重叠时(注意：这里SR的PUCCH可以是一个时隙的PUCCH，也可以是跨时隙重复的PUCCH，时域重叠可以是在一个或多个时隙中时域重叠，也可以是一个跨时隙的PUCCH在多个时隙中和 多个SR分别时域重叠)，在这种情况下，跨多个时隙的PUCCH应该如何传输，且携带SR信息，且不降低PUCCH的性能呢？PUCCH跨多个时隙重复传输主要是为了提升上行覆盖，即利用多个时隙中的PUCCH传输的UCI进行合并解码提升性能。
针对上述问题，提出以下方法A和方法B。
方法A
对于UE，跨W(W大于0)个时隙重复传输的PUCCH格式3,4在一个或多个时隙中与Q(大于0且小于等于Qmax)个SR的PUCCH出现时域重叠，UE总是在所述W个时隙中传输的PUCCH承载UCI末尾均增加X比特，X比特的比特数为
Figure PCTCN2019082161-appb-000006
或
Figure PCTCN2019082161-appb-000007
Qmax为***中一个UE能被同时配置的最大SR数量，这样，X将是一个固定值。X比特的比特取值根据UE要传输的有SR请求的SR编号进行确定，或者取值均为0。然后，对于UCI比特末尾串接X比特得到的数据使用polar码进行编码，并发送。
上述方式优先被考虑应用于在PUCCH的起始时隙中，就出现了和一个或多个SR时域重叠。或，上述方式优先被考虑应用于在PUCCH的起始时隙中，就出现了和一个或多个SR时域重叠，且两者起始符号相同。或，上述方式优先被考虑应用于在PUCCH的起始时隙中，就出现了和一个或多个SR时域重叠，且SR的起始符号早于PUCCH的起始符号。
方法B
对于UE，跨W(W大于0)个时隙重复传输的PUCCH格式3,4在一个或多个时隙中与Q(大于0且小于等于Qmax)个SR的PUCCH出现时域重叠，UE在时域重叠的时隙中，采用对PUCCH信道进行打孔或速率匹配，或在PUCCH信道预留资源的方式来传输X比特。所述X比特的比特数为
Figure PCTCN2019082161-appb-000008
或
Figure PCTCN2019082161-appb-000009
其中，所述Qmax为通信***中所述UE能被同时配置的最大SR数量；所述Q为所述通信***给UE配置的SR数量(如记为Q1)；或所述Q为所述W个时隙中有时域重叠的时隙中，具有最多时域重叠的SR数量(记为Q2)；或所述Q为所述W个时隙中有时域重叠的时隙中，时域重叠的SR数量(这里在不同的时隙中Q可能取值不同，记为Q3)。所述X比特的比特取值为UE要传输的有SR请求的SR编号，或者所述Q个SR均为无SR请求时，所述X比特的比特取值均为0，其中，SR编号为所述Q个SR的SR索引按照升序或降序排列后的编号；所述预留资源是按照Qmax或Q值对应的所述X比特数确 定的。一个例子为Q的不同取值说明：例，***为UE最大允许配置8个SR，即Qmax为8，应用与所述W个时隙中有时域重叠的时隙或所有W个时隙。***为UE总共配置了4个SR，那么即UE此时共有4个SR，即Q1＝4，应用与所述W个时隙中有时域重叠的时隙或所有W个时隙。但是在W个(如W＝4)时隙中，第一个时隙中有1个SR与PUCCH格式3/4时域重叠，第二、四个时隙中没有SR与PUCCH格式3/4时域重叠，第三个时隙中有2个SR与PUCCH格式3/4时域重叠(此时配置了4个SR但是重叠的SR个数是小于等于4)，那么，4个时隙中，时域重叠SR数量最多的时隙为第三个时隙，重叠SR为2个，即Q2＝2，应用与所述W个时隙中有时域重叠的时隙或所有W个时隙。此时第一个时隙中Q3＝1，第二、四个时隙没有时域重叠的SR，Q3为无取值或0，第三个时隙中Q3＝2。
所述X比特的比特取值为UE要传输的有SR请求的SR编号，或者所述Q个SR均为无SR请求时，所述X比特的比特取值均为0，其中，SR编号为所述Q个SR的SR索引按照升序或降序排列后的编号。
传输X bit的时隙可以是所述W个时隙中第一个出现时域重叠的时隙以及后续的时隙(后续时隙中没有时域重叠的时隙被包括或不被包括)传输X比特，其余时隙(如果有)不传输Xbit。或者所有W个时隙均传输X bit，不管时隙中是否有上述的时域重叠。
例如，在PUCCH映射的时频资源中，预留一部分PUCCH的资源用来传输X比特，预留的资源按照X bit传输时需要的RE数量进行预留。显然，这里需要先按照X bit传输时采用调制方式，码率，层数等计算，然后按照协议TS 38.212的6.2.7节进行X bit与UCI的复用处理。注意，此时所述6.2.7节中的HARQ-ACK比特信息等价于本申请的X bit通过速率匹配后的数据，所述6.2.7节中的UL-SCH中的数据(Data)等价于本申请中承载在PUCCH中的UCI信息。
例如，对于一个跨W个时隙重复的PUCCH格式3/4，在所述W个时隙中，一个或多个时隙中分别出现了所述PUCCH格式3/4与该UE的一个或多个SR的PUCCH时域重叠(这里将W个时隙中出现时域重叠的时隙称为时域重叠的时隙，将W个时隙中未出现时域重叠的时隙称为非时域重叠的时隙)，每个时域重叠的时隙中可能重叠的SR的个数不同。但是每个时域重叠的时隙中，如果存在有SR请求时，UE只能选择一个有SR请求的SR传输，使用X个比特的 比特取值表示，X的定义和取值见前文；
X个比特进行编码调制后，得到X比特对应的待传输信息Y1，例如按照相关PUCCH中的UCI编码的规则进行调制编码。
PUCCH格式3/4中的UCI进行编码调制后，得到对应的待传输信息Y2。
将Y1和Y2进行速率匹配，最终得到传输信息Y。
这里为了保证W个时隙中传输的PUCCH格式3/4进行合并译码(合并译码需要满足多个条件，例如编码时母码使用的母码编码矩阵要相同，这个和期望传输的比特数有关，为了保证母码编码矩阵相同，本文使得W个时隙中，每个时隙中最终传输的信息相等)，在所述W个时隙中，不管该时隙中是否发生上述的时域重叠，每个时隙中均传输信息Y。即，每个时隙中都使用X个比特对PUCCH格式3/4进行速率匹配了。这样，每个时隙中，PUCCH格式3/4期望传输的信息数都是相等的，所以使用的编码母码矩阵相同，所以可以保证所述W个时隙中PUCCH格式3/4可以合并。也有一个的例子，当上述的时域重叠在所述W个时隙中第一个时隙中有时域重叠时，那么UE启动上述方式传输。
也有一个特殊的例子，当上述的时域重叠发生时，且在所述W个时隙中，第一个时隙中有时域重叠，那么UE就所有时隙中按照第一个时隙中的确定的X(比特数和比特取值)速率匹配PUCCH格式3/4，然后在每个时隙中都传输，除了第一个时隙外，其余W-1个时隙都丢弃SR。这种方式也能保证W个时隙中PUCCH格式3/4的合并译码，且X比特也能被保证合并译码。
也有一个特殊的例子，当上述的时域重叠发生时，且在所述W个时隙中，第一个时隙中有时域重叠，那么UE就所有时隙中按照第一个时隙中的确定的X(比特数和比特取值)比特串接在PUCCH格式3/4的UCI末尾，然后联合编码，在每个时隙中都传输，除了第一个时隙外，其余W-1个时隙都丢弃SR。这种方式也能保证W个时隙中PUCCH格式3/4的合并译码，且X比特也能被保证合并译码。
应用实施例3
解决问题：对于一个UE，一个PUCCH和PUSCH时域重叠时，UE该怎么传输PUCCH信道中的信息，尤其是PUCCH中承载的是对于时延敏感业务的信息时。
在相关技术中，如果PUCCH和PUSCH完全重叠，或PUCCH和PUSCH的起始符号相同，UE将承载在PUCCH的UCI信息(包括HARQ-ACK、SR、 CSI的一个或多个)通过PUSCH信道进行传输，丢弃PUCCH信道。但是这种做法被使用为增强移动宽带(Enhance Mobile Broadband，eMBB)，即时延要求不苛刻的业务。此时，UCI通过PUSCH传输，UCI在PUSCH中的映射位置被进行了严格的定义(可以查阅3GPP TS 38.212)，在这个定义中，HARQ-ACK被映射从PUSCH的DMRS符号之后开始映射，DMRS符号位于PUSCH的可能非第一个OFDM。也就是说承载HARQ-ACK的PUCCH信道的符号位置在UCI映射到PUSCH时会发生变化。
例子1，DMRS在PUSCH的第3个符号中，PUCCH有2个符号，和PUSCH的前2个符号时域重叠，此时按照相关技术，该PUCCH承载的HARQ-ACK将被映射到第4个及其之后符号中，这样PUCCH的时域位置被改变了，如果PUCCH承载的是低时延高可靠通信(Ultra Reliability and Low Latency Communication，URLLC)业务信息，那么这个时域位置改动将可能导致业务传输失败。
还有例子2，实际中也存在：UE的PUSCH占用的符号是：符号2～符号13(编号从0开始)，假设符号3为DMRS符号；PUCCH占用的符号是：符号11～符号13。显然，时域重叠符号11～符号13。这里假设PUCCH承载的是URLLC业务信息，例如HARQ-ACK。URLLC是对于时延要求非常苛刻的业务，意味着发送的时域位置不能被轻易修改。那么这种情况下怎么处理PUCCH传输呢？
下面的PUCCH和PUSCH时域重叠中，PUCCH可以是跨时隙重复的PUCCH，PUSCH也可以是跨时隙重复的PUSCH。下面处理的方式都是通用的。处理方法包括以下三种：
方法1
对于一个UE，PUCCH和PUSCH时域重叠时，UE将PUCCH承载的UCI通过PUSCH信道进行传输，且在PUSCH中仅使用PUCCH和PUSCH时域重叠的符号来进行UCI的映射和发送。PUCCH被丢弃。
例如，在上述的例子1中，UCI就映射在PUSCH的前2个符号中，而不是从PUSCH的第4个符号开始映射。在例子2中，UCI被映射都符号11～符号13中，而不是从符号4开始映射。这样以保证PUCCH的时域位置不变。
这种方式尤其适用于PUCCH和PUSCH起始符号相同的情况，因为在进行PUSCH和PUCCH能被同时获知待传输的信息。
方法2
在方法1中，UCI在PUSCH中映射符号可能距离DMRS很远，此时UCI的解码性能会下降(例如在例子2中)。为了克服这个缺点，采用下面的方式。
对于一个UE，PUCCH和PUSCH时域重叠时，UE将PUCCH承载的UCI通过PUSCH信道进行传输，且在PUSCH中仅使用PUCCH和PUSCH时域重叠的符号来进行UCI的映射和发送。PUCCH被丢弃。在UCI信息中穿插用于UCI解码RS信息，然后将穿插了解码RS的UCI信息作为新的UCI信息映射到PUCCH与PUSCH时域重叠的符号中。这样，UCI能够使用穿插的解码RS进行解码，从而克服上述问题。
其本质就是，在UCI信息比特或UCI信息调制符号的约定位置处***解码RS比特或解码RS调制符号，形成新的一系列UCI信息或一系列UCI信息调制符号，然后再映射到PUCCH和PUSCH重叠符号上发送。
方法3
对于一个UE，PUCCH和PUSCH时域重叠时，UE将PUCCH和PUSCH重叠的符号中的PUSCH打孔，即重叠符号中不传输PUSCH，在重叠的符号中传输所述PUCCH。此时，PUCCH可以使用重叠符号中PUSCH的频域资源，也可以使用PUCCH自身的频域资源。此时PUCCH信道被传输了。
例如，在上述的例子1中，PUSCH的前2个符号会被打掉，PUCCH会在前2个符号中传输。在例子2中，PUSCH的符号11～符号13被打孔，PUCCH会在符号11～符号13中传输。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本公开各个实施例所述的方法。
