Description

一种上行控制信息的传输方法、装置及存储介质 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的传输方法、装置及存储介质。
背景技术
为了更好的满足日益增长的业务需求，国际电信联盟(international telecommunication union，ITU)为第五代移动通信系统(5 rdgeneration，5G)以及未来的移动通信系统定义了多种业务，例如：增强型移动宽带(enhanced mobile broadband，eMBB)、高可靠低时延通信(ultra-reliable and low-latency communications，URLLC)以及海量机器类通信(massive machine type communications，mMTC)。
对于不同的业务，如何实现数据传输的高可靠性，是5G比较关键的技术。为了实现数据传输的高可靠性，一般可采用混合自动重传请求(hybrid automatic repeat request，HARQ)反馈机制来保证数据传输的可靠性。HARQ反馈机制是指接收端成功接收到发送端发送的数据后，向发送端反馈肯定应答(acknowledgment，ACK)，未成功接收到发送端发送的数据后，向发送端反馈否定应答(negative acknowledgment，NACK)。由于HARQ反馈机制是在数据传输失败时请求重传，从而可保证数据传输的可靠性。通常ACK或NACK承载于上行控制信息(uplink control information，UCI)中。
现有技术中，数据的接收端(作为反馈信息的发送端)向数据的发送端发送反馈信息(如ACK或NACK)是在确定的资源上发送的。当不同业务的反馈信息对应的资源冲突时，会丢掉其中一个业务的反馈信息。例如URLLC的UCI的反馈资源与eMBB的UCI的反馈资源冲突时，会将eMBB的UCI直接丢掉，如此，会影响eMBB的下行吞吐量。
发明内容
本申请提供一种上行控制信息的传输方法、装置及存储介质，用于尽量避免因直接丢弃第二HARQ码本影响对应业务的下行吞吐量。
第一方面，本申请提供一种上行控制信息的传输方法，该方法包括当第一UCI的第一时频资源对应的第一时域资源与第二UCI的第二时频资源对应的第二时域资源部分重叠或完全重叠时，对第二UCI中的第二HARQ码本进行压缩，并在第三时频资源上向网络设备发送压缩后的第二HARQ码本和第一UCI。
该方法可由第一通信装置执行，第一通信装置可以是终端设备，或终端设备中的模块，例如芯片。下面以终端设备执行该方法为例进行描述。
基于该方案，当第一时域资源与第二时域资源部分重叠或完全重叠时，终端设备通过对第二HARQ码本进行压缩，之后向网络设备发送压缩后的第二HARQ码本和第一UCI。即不再直接将第二HARQ码本丢弃，有助于避免因直接丢弃第二HARQ码本，导致网络设备需要将第二HARQ码本对应的物理下行共享信道(physical downlink shared channel，PDSCH)都重传，从而影响对应的业务的下行吞吐量的问题。而且，该方案还可以保证第一UCI的时延要求。
在一种可能的实现方式中，终端设备可将S比特的第二HARQ码本压缩为L比特。 其中，L与第一UCI的比特数和第三时频资源的大小相关，S和L为正整数，且S为大于L的整数。
本申请示例性地给出了如下六种将S比特的第二HARQ码本压缩为L比特的可能的实现方式。
实现方式一，终端设备从第二HARQ码本的第一个比特开始，将S比特中前M*(L-1)中的每M比特的HARQ信息压缩为1比特的HARQ信息，将S比特中的后S-M*(L-1)比特的HARQ信息压缩为1比特的HARQ信息，

表示向上取整。
进一步，可选地，终端设备可将M比特的HARQ信息进行逻辑与的运算，得到1比特的HARQ信息。进一步，对S比特中的后S-M*(L-1)比特的HARQ信息进也行逻辑与的运算，得到1比特的HARQ信息。如此，在网络设备接收到压缩后的1比特的HARQ信息为ACK时，则可确定该压缩后的1比特的HARQ信息对应的M比特的HARQ信息对应的数据就不需要再重传。
实现方式二，终端设备可将S比特中前2 N*(L-1)中的每2 N比特的HARQ信息压缩为1比特的HARQ信息，将S比特中后S-2 N*(L-1)比特的HARQ信息压缩为1比特的HARQ信息，
Figure PCTCN2019109715-appb-000003
Figure PCTCN2019109715-appb-000004
表示向上取整，/表示除号。
进一步，可选地，终端设备可将2 N比特的HARQ信息进行逻辑与的运算，得到1比特的HARQ信息。进一步，可对S比特中后S-2 N*(L-1)比特的HARQ信息也进行逻辑与的运算，得到1比特的HARQ信息。如此，在网络设备接收到压缩后的1比特的HARQ信息为ACK时，则相应地的2 N比特的HARQ信息对应的数据就不需要再重传。因此，通过逻辑与的方式将2 N比特的HARQ信息压缩为1比特的HARQ信息效果较好。
实现方式三，终端设备将S比特的第二HARQ码本编码为L比特。例如，可采用里德-穆勒(reed muller，RM)矩阵编码。
实现方式四，终端设备将第二HARQ码本的最后(S-L+1)比特的HARQ信息压缩为1比特的HARQ信息。
进一步，可选地，终端设备对(S-L+1)比特的HARQ信息进行逻辑与的运算，得到1比特的HARQ信息。
通过该实现方式四，当网络设备接收到的压缩后的1比特的HARQ信息为ACK时，对应的(S-L+1)比特的HARQ信息对应的数据不需要再重传。而且，在第一UCI与第二HARQ码本级联、且第一UCI对应的物理下行控制信道(physical downlink control channel，PDCCH)和第二UCI对应的PDCCH漏检率不同的场景中，通过将第二HARQ码本中的最后(S-L+1)比特的HARQ信息压缩为1比特的HARQ信息，有助于避免由于第二HARQ码本对应的最后一个PDCCH丢失时，造成第二HARQ码本的长度与网络设备期望接收的长度不同，从而造成网络设备接收错误的问题。这是因为将第二HARQ码本中的最后(S-L+1)比特的HARQ信息压缩为1比特的HARQ信息，只有最后(S-L+1)比特的HARQ信息对应的PDCCH都漏检，才会造成第二HARQ码本的长度与网络设备期望接收的长度不同，但是最后(S-L+1)比特的HARQ信息对应的PDCCH都漏检的概率很低。
实现方式五，终端设备从S比特的HARQ信息中截取L比特的HARQ信息。通过该实现方式五，有助于提高终端设备对第二HARQ码本压缩的效率，且压缩方式较简单。而且有助于避免由于第二HARQ码本对应的最后一个PDCCH丢失时，造成第二HARQ码本的长度与网络设备期望接收的长度不同，从而造成网络设备接收错误的问题；进而不会 影响到第一UCI传输的可靠性。
实现方式六，根据第二HARQ码本是基于CBG还是基于CBG和TB，可分如下两种情形。
情形A，第二HARQ码本为基于码块组(code block group，CBG)的HARQ码本。
基于该情形A，终端设备可将基于CBG的第二HARQ码本修改(修改也可理解为转换、或者确定)为基于传输块(transport block，TB)的第二HARQ码本。
情形B，第二HARQ码本为基于CBG和基于TB的HARQ码本。
基于该情形B，终端设备可将基于CBG和基于TB的第二HARQ码本修改为基于TB的第二HARQ码本。
通过上述实现方式六，将基于CBG的第二HARQ码本修改为基于TB的第二HARQ码本，可有效减少第二HARQ码本的比特数。当第二HARQ码本与第一UCI一起发送时，第二HARQ码本的比特数越小，对第一UCI的影响越小。
本申请中，示例性地给出了如下五种确定发送压缩后的第二HARQ码本和第一UCI所在的时频资源(即第三时频资源)的方式。
方式一，第三时频资源是基于第一时域资源的结束符号的索引和第二时域资源的结束符号的索引确定的。
基于该方式一，又可分如下两种情形。
情形1，第一时域资源的结束符号的索引小于第二时域资源的结束符号的索引。
在该情形1中，第三时频资源为第一时频资源。
情形2，第一时域资源的结束符号的索引大于或等于第二时域资源的结束符号的索引。
在该情形2中，第三时频资源为第一时频资源和第二时频资源中包括的资源元素较多的一个时频资源。
方式二，第三时频资源为第一时频资源。
基于上述方式一和方式二，在一种可能的实现方式中，终端设备将压缩后的第二HARQ码本和第一UCI进行级联。第二HARQ码本级联(也可称为复接)于第一UCI之前，或者第二HARQ码本级联于第一UCI之后。
在一种可能的实现方式中，终端设备还可根据压缩后的第二HARQ码本的比特数，确定承载压缩后的第二HARQ码本的第四时频资源。
方式三，第三时频资源可基于上述确定出的第四时频资源对应的时域资源与第一时频资源的第一时域资源是否重叠来确定，可分如下两种情形。
情形a，当第四时频资源对应的时域资源与第一时频资源的第一时域资源部分重叠或完全重叠。
基于该情形a，在一种可能的实现方式中，终端设备将压缩后的第二HARQ码本与第一UCI进行级联，根据压缩后的第二HARQ码本和第一UCI的总比特数，确定第三时频资源。如此，既可以保证第一UCI的时延，又可增加传输第二HARQ码本的几率。基于该情形a，在另一种可能的实现方式中，终端设备可在第五时频资源上向网络设备发送压缩后的第二HARQ码本，在第一时频资源上向网络设备发送第一UCI，其中，第五时频资源为第四时频资源中与第一时频资源不重叠的时频资源。
情形b，第四时频资源对应的时域资源与第一时频资源的时域资源不重叠。
基于该情形b，终端设备在第一时频资源上向网络设备发送第一UCI；终端设备在第 四时频资源上向网络设备发送压缩后的第二HARQ码本。
方式四，直接根据压缩后的第二HARQ码本和第一UCI级联后的总比特数，确定新的时频资源，可将该新的时频资源确定为第三时频资源。
方式五，第三时频资源基于第一时频资源的第一时域资源与第二时频资源的第二时域资源部分重叠的情况来确定。
基于该方式五，终端设备在第六时频资源上向网络设备发送压缩后的第二HARQ码本，并在第一时频资源上向网络设备发送第一UCI，其中，第六时频资源为第二时频资源中与第一时频资源不重叠的时频资源。
基于上述方式五，终端设备可确定第二时域资源和第一时域资源重叠的时域资源与第二时域资源的比值，若该比值小于或等于第一预设值，则可将第二时频资源中与第一时频资源不重叠的时频资源确定为第六时频资源。
在另一种可能的实现方式中，第二HARQ码本的比特数大于第二预设值。
第二方面，本申请提供一种上行控制信息的传输方法，该方法包括在第三时频资源上接收来自终端设备的上行信道，上行信道承载第一上行控制信息UCI和第二UCI，当第一UCI的第一时频资源对应的第一时域资源与第二UCI的第二时频资源对应的第二时域资源部分重叠或完全重叠时，对第二UCI中被压缩的第二混合自动重传请求HARQ码本进行解压缩。
该方法可由第二通信装置执行，第二通信装置可以是网络设备，或网络设备中的模块，例如芯片。下面以第二通信装置是网络设备为例进行描述。
基于该方案，网络设备在第三时频资源上接收来自终端设备的第一UCI和第二UCI，当第一UCI的第一时频资源对应的第一时域资源与第二UCI的第二时频资源对应的第二时域资源部分重叠或完全重叠时，可对第二UCI中被压缩的第二HARQ码本进行解压缩，得到第二UCI中的第二HARQ码本。如此，网络设备可根据第二HARQ码本确定是否需要重传第二HARQ码本对应的PDSCH。也就是说，网络设备可能不需要对全部的第二HARQ码本对应的PDSCH都进行重传，只需对HARQ信息为NACK的相应PDSCH进行重传。
在一种可能的实现方式中，可将L比特的被压缩的第二HARQ码本解压缩为S比特，其中，S和L为正整数，且S为大于L的整数，L与第一UCI的比特数和第三时频资源的大小相关。
进一步，可选地，可从被压缩的第二HARQ码本的第一个比特开始，将L比特中的前L-1个比特中的每一个比特的HARQ信息解压缩为M比特的HARQ信息，将L比特中的最后一个比特解压缩为S-M*(L-1)比特的HARQ信息，其中，

在一种可能的实现方式中，将L比特中的前L-1个比特中的每一个比特的HARQ信息解压缩为M比特的HARQ信息，具体可为：将取值为1的一个比特解压缩为M个取值为1的比特，将取值为0的一个比特解压缩为M个取值为0的比特。进一步，将L比特中的最后一个比特解压缩为S-M*(L-1)比特的HARQ信息具体可以为：将取值为1的最后一个比特解压缩为S-M*(L-1)个取值为1的比特，将取值为0的最后一个比特解压缩为S-M*(L-1)个取值为0的比特。
在一种可能的实现方式中，可将L比特的被压缩的第二HARQ码本解码为S比特。
在一种可能的实现方式中，若第二HARQ码本为基于CBG的HARQ码本，可确定基 于CBG的第二HARQ码本被修改为基于TB的第二HARQ码本。若第二HARQ码本为基于CBG和基于TB的HARQ码本；确定基于CBG和基于TB的第二HARQ码本被修改为基于TB的第二HARQ码本。

以下，对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)HARQ技术
在无线通信系统中，收发双方通常采用HARQ技术来保证数据传输的可靠性。其中，HARQ技术将前向纠错编码(forward error correction，FEC)与自动重传请求(automatic repeat request，ARQ)相结合。具体可为：TB编码后，第一次传输时发送信息比特和一部分冗余比特，如果接收端能够正确译码，则反馈ACK给发送端，则发送端确认接收端 已经成功接收到所对应的信息比特，认为该TB已经成功传输。如果接收端不能够正确译码，则反馈NACK给发送端。发送端接收到NACK后，则再进一步传输一部分信息比特和/或冗余比特给接收端，称为重传数据，接收端接收到重传数据后，与之前接收到的数据合并后进行译码，如果加上重传的冗余比特仍然无法正常解码，则接收端反馈NACK等待发送端进行再次重传。
在一种可能的实现方式中，接收端接收到来自发送端的数据后，基于是否正确接收到数据生成HARQ码本。在NR的版本15(release 15，R15)的协议中高层可配置两种类型HARQ码本，一种是半静态的HARQ码本，一种是动态的HARQ码本。如下分别详细介绍半静态的HARQ码本和动态的HARQ码本的生成过程。
半静态HARQ码本的生成过程：首先确定一个PDSCH接收候选位置集合，即终端设备可能会接收PDSCH的位置集合，根据该集合在一个物理层上行控制信道(physical uplink control channel，PUCCH)上传输相应HARQ信息。对于一个激活下行带宽部分(bandwidth part，BWP)，一个激活上行BWP，终端设备可基于PDSCH-HARQ timing{K1}集合、PDSCH时域资源分配表格相应的行索引集合、以及上行BWP和下行BWP的子载波间隔(subcarrier space，SCS)和帧结构配比，确定PDSCH接收候选位置集合。终端设备具体可以确定一个服务小区，根据PDSCH接收候选位置集合，每个PDSCH接收候选位置预留1比特。然后遍历载波聚合(Carrier aggregation)下的全部服务小区，生成相应的半静态HARQ码本。如图2a所示，为2个成员载波(component carrier，CC)载波聚合，其中，K1＝{1，2，3}，K1是以时隙为单位的，终端设备基于PUCCH和K1的集合生成半静态HARQ码本，可能出现PDSCH接收的位置有6个，相应的HARQ的排列顺序和个数也确定了，即半静态码本的大小为6，排序为HARQ1，HARQ2，HARQ3，HARQ4，HARQ5，HARQ6。
如图2b所示，在确定可能出现PDSCH接收的位置后，终端设备若接收了3个PDSCH且根据相应K1均需要在时隙4的同一个PUCCH上反馈，且PDSCH1、PDSCH2、PDSCH3的译码结果分别是成功、失败、成功，则半静态HARQ码本为100001，其中1代表ACK，0代表NACK。
需要说明的是，在NR R15中，网络设备可使用高层配置PDSCH与HARQ定时信息(timing)的集合，即{PDSCH-to-HARQ timing}，在DCI中使用PDSCH-to-HARQ timing字段来指示上述集合中的一个值K1。其中，在NR R15中，一个时隙最多只能发一个承载HARQ的PUCCH，也就是说，在R15中，PDSCH-to-HARQ timing是时隙粒度的，如图2c所示，若终端设备在时隙n收到PDSCH，且K1＝2，则终端设备在时隙n+2发送第二UCI(即图2c中阴影所示的时隙)。在NR版本16(release 16，R16)中，支持一个时隙可以发送多个承载HARQ的PUCCH，也就是说，在NR R16中，PDSCH-to-HARQ timing可以是子时隙粒度的，可参阅图2d，K1＝2，则终端设备在子时隙n+2发送第二UCI(即图2d中阴影所示的子时隙)。
动态HARQ-ACK码本的生成过程：首先确定PDCCH监听位置集合，按照PDCCH监听位置的升序顺序，固定一个PDCCH监听位置，遍历载波聚合下的全部服务小区，然后遍历全部PDCCH监听位置，在该顺序下根据PDCCH生成相应的HARQ。半持续调度(semi persistent scheduling，SPS)PDSCH的HARQ放在根据PDCCH生成的HARQ信息的尾部。如图2e所示，PDCCH1中指示K0＝0，K1＝3；PDCCH2中指示K0＝0，K1＝2，PDCCH3中指示K0＝0，K1＝1，其中，K0等于PDCCH所在时隙和PDSCH所在时隙的时间间隔， 以时隙为单位。则PDCCH1、PDCCH2、PDCCH3调度的PDSCH相应的HARQ均需要在时隙4中的同一个PUCCH上反馈。假设PDCCH1、PDCCH2、PDCCH3调度的PDSCH的译码结果分别为成功、失败、成功，则动态HARQ码本为101。
2)TB
通常会将一个TB分为多个码块(code block，CB)，或者也可理解为，一个TB由多个CB组成。为了提高频谱利用率，可将多个CB分成一个组，称为CBG。如图2f所示，示例性示出了一种CB、CBG和TB的关系示意图。n个CB组成一个CBG，N个CBG组成一个TB，其中，n和N均为正整数。需要说明的是，在NR中，一个TB最多可配置8个CBG。在接收端，可为每个CBG是否被正确接收生成HARQ信息，如ACK或NACK。如果有N个CBG，则可生成N比特的HARQ信息，每一比特HARQ信息可表示对应的CBG是否被正确接收，例如，CBG被正确接收，生成ACK；CBG未被正确接收，生成NACK。发送端接收到N比特HARQ信息后，如果某个CBG对应的HARQ信息比特为NACK，则只需要重传该CBG，已经被正确接收到的CBG不需要再重传。进一步，在NR的下行控制信息(downlink control information，DCI)中有码块组传输信息(code block group transmission information，CBGTI)字段，用于指示哪些CBG被重传。
3)UCI
UCI可包括HARQ信息、信道状态信息(channel state information，CSI)和调度请求(scheduling request，SR)中的至少一个。具体的，UCI可包括HARQ信息、SR、CSI、CSI和HARQ信息、HARQ信息和SR、SR和CSI、CSI和SR和HARQ信息。终端设备可以通过物理上行控制信道(physical uplink control channel，PUCCH)或物理上行共享信道(physical uplink shared channel，PUSCH)发送给网络设备。
在5G通信系统中，需要具备比4G更高的性能。在NR R15的协议中定义了新的空口接入技术，以支持0.1～1Gbps的用户体验速率，每平方公里一百万的连接数密度，毫秒级的端到端时延，每平方公里数十Tbps的流量密度，每小时500Km以上的移动性和数十Gbps的峰值速率。其中，用户体验速率、连接数密度和时延为5G最基本的三个性能指标。5G的三大应用场景和需求包括：eMBB、mMTC和URLLC。其中，URLLC可应用于无人驾驶或工业控制等，要求低时延高可靠。低时延的具体要求为端到端0.5ms时延，空口信息交互来回1ms时延，高可靠的具体要求为误块率(block error rate，BLER)达到10 -5，即，数据包的正确接收比例达到99.999％。为了实现数据高可靠的传输，一种可行的方式是接收端针对发送端发送的数据做出相应的反馈，从而保证通信链路的高可靠性。结合上述图1，网络设备101可将数据发送至终端设备102，此时网络设备101相当于发送端，终端设备102相当于接收端；终端设备102接收到数据之后，向网络设备101发送针对接收的数据的HARQ信息，此时网络设备101相当于接收端，终端设备102相当于发送端。终端设备102针对网络设备101发送的数据做出反馈时，是在确定的时频资源上反馈的。此时，终端设备102可能需要同时向网络设备101发送多个HARQ信息，多个HARQ信息所属的业务的可能是不同的，为了保证超高可靠低时延的业务需求，通常会将时延和可靠性要求较低的业务的HARQ信息丢弃。例如，当用于传输URLLC业务的HARQ信息的时频资源对应的时域资源与用于传输eMBB的HARQ信息的时频资源对应的时域资源部分重叠或完全重叠时，为了保证URLLC业务的数据能超低时延高可靠的传输，一般将eMBB的HARQ信息直接丢弃。然而由于eMBB的HARQ信息(也称为HARQ-ACK码本)一般较 大，总是丢掉eMBB的HARQ信息可能会影响eMBB的下行吞吐量。
可以理解的是，PDCCH、PDSCH、PUCCH和PUSCH仅仅是下行控制信道、下行数据信道、上行控制信道和上行数据信道的一种举例，这些信道在不同的通信系统中可能会有不同的名字，本申请对信道的具体名字并不做限定。
鉴于此，本申请提出了一种上行控制信息的传输方法，以减少或尽可能避免因直接丢弃上行控制信息造成该业务的下行吞吐量受影响。
本申请提供的一种上行控制信息的传输方法，该方法可以应用于如上图1所示的通信系统中。另外，该方法可由两个通信装置执行，这两个通信装置例如为第一通信装置和第二通信装置，其中，第一通信装置可以是终端设备或可应用于终端设备的模块，例如芯片。第二通信装置可以是网络设备或可应用于网络设备的模块，例如芯片。下面以第一通信装置是终端设备、第二通信装置是网络设备为例，对本申请实施例提供的方法进行描述。
下面参考图3，为本申请提供的一种上行控制信息的传输方法的方法流程示意图。该方法包括以下步骤：
步骤301，当第一UCI的第一时频资源对应的第一时域资源与第二UCI的第二时频资源对应的第二时域资源部分重叠或完全重叠时，终端设备对第二UCI中的第二HARQ码本进行压缩。
其中，第一时频资源为承载第一UCI的PUCCH所占用的时频资源，第二时频资源为承载第二UCI的PUCCH所占用的时频资源。时频资源对应一个时域资源和一个频域资源。例如，一个时频资源元素(resouce element，RE)对应时域上的一个OFDM符号和频域上的一个子载波。本申请中的第一时频资源对应一个第一频域资源和一个第一时域资源，第二时频资源对应一个第二频域资源和一个第二时域资源。第一时频资源对应的第一时域资源指组成该第一时频资源的时域资源，也可理解为，承载该第一UCI的PUCCH所占用的时频资源。类似地，第二时频资源对应的第二时域资源指组成该第二时频资源的时域资源，也可理解为，承载第二UCI的PUCCH所占用的时频资源。例如，承载第一UCI的PUCCH占用的子帧长度为1ms，该子帧即为第一时域资源。再比如，承载第一UCI的PUCCH占用包括14个符号的时隙中的最后两个符号，则这14个符号中的最后两个符号即为第一时域资源。
在本申请中，时域资源(例如，第一时域资源或第二时域资源)可以是一个或多个时域单元，时域单元可以为无线帧、子帧、时隙、子时隙、迷你时隙、或时域符号。这里的时域符号可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，也可以是其它波形的符号。如果没有特别说明，本申请中的符号均指时域符号。
在一种可能的配置中，一个时隙被配置7个子时隙，一个子时隙被配置为2个符号，即一个时隙包括14个符号，可参考图4。若第一时域资源为符号3、符号4、符号5和符号6，第二时域资源为符号5、符号6、符号7和符号8，则第一时域资源与第二时域资源部分重叠，重叠部分的时域资源为符号5和符号6。
本申请中，第一时频资源和第二时频资源可以是网络设备通过DCI发送给终端设备的。例如，网络设备可以向终端设备指示承载第一UCI的PUCCH所在的第一时频资源对应的第一时域资源，以及承载第二UCI的PUCCH所在的第二时频资源对应的第二时域资源。例如，可基于NR R15中的{PDSCH-to-HARQ timing}，或者NR R16中的{PDSCH-to-HARQ timing}。
步骤302，终端设备在第三时频资源上向网络设备发送压缩后的第二HARQ码本和第一UCI。相应地，网络设备在第三时频资源上接收来自终端设备的上行信道，其中，上行信道可承载第一UCI和第二UCI。
此处，终端设备可以将压缩后的第二HARQ码本和第一UCI进行级联后，向网络设备发送压缩后的第二HARQ码本和第一UCI；或者也可以将压缩后的第二HARQ码本和第一UCI分别向网络设备发送。另外，该上行信道可以是上行控制信道，也可以是上行数据信道。
步骤303，网络设备对第二UCI中被压缩的第二HARQ码本进行解压缩。
该步骤303是在第一UCI的第一时频资源对应的第一时域资源与第二UCI的第二时频资源对应的第二时域资源部分重叠或完全重叠时执行的。其中，网络设备可根据终端设备对第二HARQ码本进行压缩的实现方式，对被压缩的第二HARQ码本进行解压缩，从而可确定出被压缩的第二HARQ码本中每一比特HARQ信息对应几比特第二HARQ码本中的HARQ信息以及解压缩后每比特HARQ信息对应的PDSCH是否需要重传。也可以理解为，网络设备可根据被压缩的第二HARQ码本中每一比特HARQ信息，确定该比特HARQ信息对应的PDSCH是否需要重传。
从上述步骤301至步骤303可以看出，当第一时域资源与第二时域资源部分重叠或完全重叠时，终端设备通过对第二HARQ码本进行压缩，之后向网络设备发送压缩后的第二HARQ码本和第一UCI。即不再直接将第二HARQ码本丢弃，有助于避免因直接丢弃第二HARQ码本，导致网络设备需要将第二HARQ码本对应的PDSCH都重传，从而影响对应的业务的下行吞吐量的问题。而且，基于该方案还可以保证第一UCI的超高时延需求。
本申请中，终端设备可将S比特的第二HARQ码本压缩为L比特，其中，S和L为正整数，且S为大于L的整数，L与第一UCI的比特数和第三时频资源的大小相关。
示例性地，可通过如下方式确定L：根据第一UCI的比特数和传输第一UCI的最大码率，确定出第一UCI需要使用的最小时频资源，根据网络设备为其配置的第一时频资源的大小与确定出的最小时频资源的大小的差值，可确定出剩余时频资源的大小，该剩余时频资源可用于承载压缩后的第二HARQ码本。进一步可选地，可根据剩余时频资源的大小和传输压缩后的第二HARQ码本的码率，确定出第二HARQ码本需要压缩为L比特。其中，码率等于信道编码前的比特数除以星座图映射前的比特数，信道编码前的比特数即为UCI的比特数，星座图映射前的比特数等于时频资源包括的RE的数量乘以一个调制符号所能承载的比特数。不同调制方式下的调制符号所能承载的比特数不同。例如，调制方式为二进制相移键控(binary phase shift keying，BPSK)、正交相移键控(quadrature phase shift keying，QPSK)、16正交振幅调制(quadrature amplitude modulatio，QAM)、64QAM和256QAM下的一个调制符号所能承载的比特数分别为2比特、3比特、4比特、6比特和8比特。也就是说，码率等于编码前的比特数/(RE的数量*一个调制符号所能承载的比特数)，其中“/”表示除号。
例如，第一UCI和第二UCI均只承载HARQ码本，假设第一UCI承载10比特HARQ信息，第二UCI承载20比特HARQ信息，终端设备可根据第一UCI和传输第一UCI的最大码率计算得出第一UCI需要使用的最小物理资源块(physical resource block，PRB)的个数为10，假设网络设备为终端设备配置的PRB个数为12，终端设备可确定出剩余2个PRB。这2个剩余的PRB可用于承载压缩后的第二HARQ码本。终端设备可根据剩余 的这2个PRB和传输第二HARQ码本的码率计算出第二HARQ码本需要压缩为L比特。
需要说明的是，网络设备可通过显示的方式为终端设备配置PRB，或者也可以通过显示结合隐式的方式为终端设备配置PRB。另外，传输压缩后的第二HARQ码本的码率可以是第二HARQ码本本身的码率，也可以是预设的码率，或者也可以是传输第一UCI的码率，本申请对此不做限定。
本申请中，示例性地给出了如下六种将S比特的第二HARQ码本压缩为L比特的可能的实现方式。其中，HARQ信息包括NACK和ACK，ACK可以用1表示，NACK可以用0表示。当然，NACK也可用1表示，ACK用0表示，本申请对此不做限定。
当ACK用1表示，NACK用0表示时，终端设备可对多个比特的HARQ信息进行逻辑与(logical AND)的运算得到1比特的HARQ信息。其中，对多个比特的HARQ信息进行逻辑与的运算是指：多个比特的HARQ信息中有一个为0，则压缩后的1比特的HARQ信息为0；多个比特的HARQ信息中全部为1，则压缩后的1比特的HARQ信息为1。当然ACK也可以用0表示，NACK可以用1表示时，终端设备可对多个比特的HARQ信息进行逻辑或(logical OR)的运算得到1比特的HARQ信息。其中，对多个比特的HARQ信息进行逻辑或的运算是指：多个比特的HARQ信息中有一个为1，则压缩后的1比特的HARQ信息为1；多个比特的HARQ信息中全部为0，则压缩后的1比特的HARQ信息为0。
在下述示例中，为了便于方案的说明，以ACK用1表示，NACK用0表示为例说明。
实现方式一
终端设备可从第二HARQ码本的第一个比特开始，将S比特中前M*(L-1)中的每M比特的HARQ信息压缩为1比特的HARQ信息，将S比特中的后S-M*(L-1)比特的HARQ信息压缩为1比特的HARQ信息。其中，
Figure PCTCN2019109715-appb-000015
Figure PCTCN2019109715-appb-000016
表示向上取整。进一步，可选地，终端设备可将M比特的HARQ信息进行逻辑与的运算，得到1比特的HARQ信息。进一步，对S比特中的后S-M*(L-1)比特的HARQ信息进也行逻辑与的运算，得到1比特的HARQ信息。在一种可选的实现方式中，终端设备可将M比特的HARQ信息进行HARQ绑定(bundling)操作即进行逻辑与(logical AND)的操作。
如图5a所示，为本申请提供的一种压缩过程示意图。以第一UCI为110，第二HARQ码本的HARQ信息为101100为例，则
Figure PCTCN2019109715-appb-000017
从第一个比特(即1)开始，可每2比特的HARQ信息压缩为1比特的HARQ信息，即对10、11、00分别进行逻辑与运算，10的逻辑与运算结果为0，11的逻辑与运算的结果为1，00的逻辑与运算的结果为0，则压缩后的第二HARQ码本为010。如此，在网络设备接收到压缩后的1比特的HARQ信息为ACK时，则可确定该压缩后的1比特的HARQ信息对应的M比特的HARQ信息对应的数据就不需要再重传。而且，由于距离越近的TB，信道环境越相似，译码结果相同的概率也越高，因此，通过逻辑与的方式将每M比特的压缩为1比特的HARQ信息的译码结果相同的概率也较高。
在另一种可能的实现方式中，终端设备可从第二HARQ码本的第一个比特开始，将每M比特的HARQ信息压缩为1比特的HARQ信息，当出现HARQ信息不够M比特时，可用ACK凑为M比特。例如，M＝3，每3比特HARQ信息进行HARQ bundling，还剩余2比特的HARQ信息时，则可给该剩余的2比特HARQ信息添加1比特的ACK，凑为3比特的HARQ信息，再压缩为1比特的HARQ信息。
实现方式二
终端设备可将S比特中前2 N*(L-1)中的每2 N比特的HARQ信息压缩为1比特的HARQ信息，将S比特中后S-2 N*(L-1)比特的HARQ信息压缩为1比特的HARQ信息。其中，
Figure PCTCN2019109715-appb-000018
Figure PCTCN2019109715-appb-000019
表示向上取整。在一种可能的实现方式中，终端设备可将2 N比特的HARQ信息进行逻辑与的运算，得到1比特的HARQ信息。进一步，也可对S比特中后S-2 N*(L-1)比特的HARQ信息也进行逻辑与的运算，得到1比特的HARQ信息。
如图5b所示，为本申请提供的另一种压缩过程示意图。以第一UCI为110，第二HARQ码本的HARQ信息为101100为例，则
Figure PCTCN2019109715-appb-000020
将每2比特的HARQ信息压缩为1比特的HARQ信息，即对10、11、00分别进行逻辑与运算，10的逻辑与运算结果为0，11的逻辑与运算的结果为1，00的逻辑与运算的结果为0。如此，在网络设备接收到压缩后的1比特的HARQ信息为ACK时，则相应地的2 N比特的HARQ信息对应的数据就不需要再重传。而且，由于距离越近的TB，信道环境越相似，译码结果相同的概率也越高，因此，2 N比特的HARQ信息的译码结果相同的概率也较高，将2 N比特的HARQ信息压缩为1比特的HARQ信息的效果越好。进一步，由于2 N比特的HARQ信息的译码结果相同的概率较高，即2 N比特的HARQ信息可能都是NACK、或者可能都是ACK的概率较高，也就是说，2 N比特的HARQ信息中有的是NACK，有的是ACK的概率比较小，如此，可有助于减少因为2 N比特中有一个NACK从而导致压缩后的HARQ为NACK，全部相应的PDSCH均被重传，造成频谱浪费以及降低下行吞吐量。
在另一种可能的实现方式中，终端设备可以从第二HARQ码本的第一个比特开始，每2 N比特的HARQ信息压缩为1比特的HARQ信息，当出现HARQ信息不够2 N比特时，可用ACK凑为2 N比特。例如，N＝1，每2比特HARQ信息进行HARQ bundling，还剩余1比特的HARQ信息时，则可给该剩余的1比特HARQ信息添加1比特的ACK，凑为2比特的HARQ信息，再压缩为1比特的HARQ信息。
实现方式三
终端设备可将S比特的第二HARQ码本编码为L比特。例如，可采用里德-穆勒(Reed Muller，RM)矩阵编码。可以理解为，S比特的第二HARQ码本为输入，经RM矩阵编码后，输出L比特的第二HARQ码本。
示例性地，长度为(L，S)的Reed-Muller码的编码方法是将生成矩阵M L×S与输入向量x S×1按矩阵相乘，对每个元素对2取模，即可以得到编码向量y L×1。其中，生成矩阵M L×S可以是协议中预定的，对2取模又称为模2运算，模2运算是一种二进制算法。模2运算包括模2加，模2减，模2乘，模2除四种二进制运算。比如，模2加是不带进位的二进制加法运算，即0和1之间的加法。0+0＝0，0+1＝1+0＝1，1+1＝0。
实现方式四
终端设备可将第二HARQ码本的最后(S-L+1)比特的HARQ信息压缩为1比特的HARQ信息。进一步，可选地，终端设备对(S-L+1)比特的HARQ信息进行逻辑与的运算，得到1比特的HARQ信息。
如图5c所示，为本申请提供的又一种压缩过程示意图。以第一UCI为110，第二HARQ码本的HARQ信息为101100为例，则S-L+1＝6-3+1＝4，可将第二HARQ码本的最后4比特的HARQ信息压缩为1比特的HARQ信息，即对1100进行逻辑与运算，得到运算结果为0，压缩后的第二HARQ码本为100。
通过该实现方式四，在第一UCI与第二HARQ码本级联、且第一UCI对应的PDCCH和第二UCI对应的PDCCH漏检率不同的场景中，通过将第二HARQ码本中的最后(S-L+1)比特的HARQ信息压缩为1比特的HARQ信息，有助于避免由于第二HARQ码本对应的最后一个PDCCH丢失时，造成第二HARQ码本的长度与网络设备期望接收的长度不同，从而造成网络设备接收错误的问题。这是因为将第二HARQ码本中的最后(S-L+1)比特的HARQ信息压缩为1比特的HARQ信息，只有最后(S-L+1)比特的HARQ信息对应的PDCCH都漏检，才会造成第二HARQ码本的长度与网络设备期望接收的长度不同，但是最后(S-L+1)比特的HARQ信息对应的PDCCH都漏检的概率很低。
实现方式五
终端设备从S比特的HARQ信息中截取L比特的HARQ信息。也可以理解为，从S比特的HARQ信息中截取L比特的HARQ信息，将剩余的(S-L)比特的HARQ信息直接丢掉。通过该实现方式五，有助于提高终端设备对第二HARQ码本压缩的效率，且压缩方式较简单。而且，在第一UCI与第二HARQ码本级联、且第一UCI对应的PDCCH和第二UCI对应的PDCCH漏检率不同的场景中，通过将S比特的第二HARQ码本中截取L比特的HARQ信息，有助于避免由于第二HARQ码本对应的最后一个PDCCH丢失时，造成第二HARQ码本的长度与网络设备期望接收的长度不同，从而造成网络设备接收错误的问题。
在一种可能的实现方式中，终端设备可截取S比特的HARQ信息中的前L比特的HARQ信息，或者也可以截取S比特的HARQ信息中的后L比特的HARQ信息，或者也可以截取S比特的HARQ信息中的中间L比特的HARQ信息，或者也可以按照一定的规律从S比特的HARQ信息中截取L比特的HARQ信息。本申请对从哪截取L比特不限定。
如图5d所示，为本申请提供的再一种压缩过程示意图。以第一UCI为110，第二HARQ码本的HARQ信息为101100为例，则L＝3，从S比特的HARQ信息的第一比特开始，截取3比特的HARQ信息，将剩余的3比特的HARQ信息丢弃，即截取L比特后的第二HARQ码本为101。
实现方式六
在该实现方式六中，可根据第二HARQ码本是基于CBG还是基于CBG和TB，分如下两种情形。其中，第二HARQ码本是基于CBG的第二HARQ码本，也可以理解为，终端设备向网络设备发送第二HARQ码本的反馈粒度为CBG级别(CBG-level)。
情形A，第二HARQ码本为基于CBG的HARQ码本。
基于该情形A，终端设备可将基于CBG的第二HARQ码本修改为基于TB的第二HARQ码本。应理解，修改为基于TB的第二HARQ码本即为压缩后的第二HARQ码本。在一种可能的实现方式中，可以将基于CBG的第二HARQ码本中每个TB对应的基于CBG的HARQ信息进行逻辑与运算。
例如，第二HARQ码本是基于CBG的第二HARQ码本为111111110000111110101010，对应有32比特，结合上述图1，一个TB最大可配置8个CBG，将基于CBG的第二HARQ码本111111110000111110101010修改为基于TB的第二HARQ码本100，基于TB的第二HARQ码本对应有3比特。特别是在第二HARQ码本的比特数较大时，如果直接丢弃第二HARQ码本，会导致多个PDSCH均需要重传，从而会影响第二UCI所属业务的下行的吞吐量。通过该实现方式六，可有助于避免该问题的出现。
情形B，第二HARQ码本为基于CBG和基于TB的HARQ码本。也就是说，第二HARQ码本包括基于CBG的第二HARQ码本和基于TB的第二HARQ码本，或者，也可理解为，第二HARQ码本包括基于CBG的HARQ子码本和基于TB的HARQ子码本。
基于该情形B，终端设备可将基于CBG和基于TB的第二HARQ码本修改为基于TB的第二HARQ码本。在一种可能实现方式中，可将该第二HARQ码本中基于CBG的第二HARQ码本修改为基于TB的第二HARQ码本。应理解，修改为TB的第二HARQ码本和第二HARQ码本中本身包括的基于TB的第二HARQ码本即为压缩后的第二HARQ码本。示例性地，第二HARQ码本是基于CBG和基于TB的HARQ码本，基于CBG的第二HARQ码本为111111110000111110101010，对应有24比特，基于TB的HARQ码本为1|0，对应2比特，即第二HARQ码本为10111111110000111110101010。结合上述图1，一个TB最大可配置8个CBG，将基于CBG的HARQ码本111111110000111110101010修改为基于TB的HARQ码本为100，修改为基于TB的HARQ码本对应有3比特，压缩后的第二HARQ码本可为修改为基于TB的HARQ码本与第二HARQ码本中本身包括的基于TB的HARQ码本级联后的10010。在另一种可能的实现方式中，可将该第二HARQ码本中基于CBG的第二HARQ码本直接丢弃，保留第二HARQ码本中包括的基于TB的第二HARQ码本。应理解，第二HARQ码本中包括的基于TB的第二HARQ码本即为压缩后的第二HARQ码本。示例性地，第二HARQ码本是基于CBG和基于TB的HARQ码本，基于CBG的HARQ码本为111111110000111110101010，基于TB的HARQ码本为10，将基于CBG的HARQ码本111111110000111110101010直接丢弃，则压缩后的第二HARQ码本为第二HARQ码本中本身包括的基于TB的HARQ码本10。
通过上述实现方式六，将基于CBG的第二HARQ码本修改为基于TB的第二HARQ码本，可有效减少第二HARQ码本的比特数。第二HARQ码本的比特数越小，对链路预算影响越小，当第二HARQ码本与第一UCI一起发送时，对第一UCI的影响越小，并且第二HARQ码本重新选择传输资源时和第一UCI冲突的概率越小。
需要说明的是，如上六种对第二HARQ码本压缩的实现方式只是举例，本申请并不限定如何对第二HARQ码本进行压缩，只要实现将S比特的第二HARQ码本压缩为L比特的方式均可。另外，选择上述的哪种实现方式对第二HARQ码本进行压缩，可以由终端设备自行选择，例如终端设备可以随机选择，或者终端设备也可以根据某些因素选择，例如终端设备需快速实现对第二HARQ码本进行压缩，则终端设备可以选择上述实现方式五。或者，选择上述的哪种实现方式对第二HARQ码本进行压缩，可以通过协议规定，也可以是基于网络设备的指示。
还需要说明的是，本申请中第二HARQ码本可以是半静态的HARQ码本，可以是动态的HARQ码本，半静态的HARQ码本和动态的HARQ码本具体可参见上述描述，此处不再赘述。
在上述步骤302中，终端设备需确定出发送压缩后的第二HARQ码本和第一UCI的第三时频资源。如下，示例性地给出了如下五种确定发送压缩后的第二HARQ码本和第一UCI的时频资源(即第三时频资源)的方式。
方式一，第三时频资源是基于第一时域资源的结束符号的索引和第二时域资源的结束符号的索引来确定的。
在该方式中，结合上述图4，若第一时域资源为符号3、符号4、符号5和符号6，第 二时域资源为符号5、符号6、符号7和符号8，则第一时域资源的结束符号的索引为6，第二时域资源的结束符号的索引为8。
基于该方式一，又可分如下两种情形。
情形1，第一时域资源的结束符号的索引小于第二时域资源的结束符号的索引。
在该情形1中，第三时频资源为第一时频资源。也就是说，终端设备可在第一时频资源上，向网络设备发送压缩后的第二HARQ码本和第一UCI。相应地，网络设备可在第一时频资源上，接收来自终端设备的压缩后的第二HARQ码本和第一UCI。如此，可保证第一UCI及时发送至网络设备。
情形2，第一时域资源的结束符号的索引大于或等于第二时域资源的结束符号的索引。
在该情形2中，第三时频资源为第一时频资源和第二时频资源中包括的资源元素较多的一个时频资源。也就是说，终端设备在第一时频资源和第二时频资源中包括的资源元素较多的一个时频资源上，向网络设备发送压缩后的第二HARQ码本和第一UCI。相应地，网络设备可在第一时频资源和第二时频资源中包括的资源元素较多的一个时频资源上，接收来自终端设备的压缩后的第二HARQ码本和第一UCI。通过该情形2，一方面，可以保证第一UCI可以及时发送至网络设备；另一方面，通过第一时频资源和第二时频资源中资源元素较多的一个发送，可以承载比特数较多的压缩后的第二HARQ码本。
结合上述图4，例如，第二时域资源若占用符号4、符号5和符号6，第一时域资源若占用符号5和符号6，则第二时域资源的结束符号的索引与第一时域资源的结束符号的索引相同，且第二时频资源包括的资源元素较多，因此，第三时域资源可为第二时频资源。
在一种可能的实现方式中，若第一UCI所属的业务为URLLC业务，第二UCI所属的业务为eMBB业务，由于eMBB业务的HARQ码本的一般较大，因此，较大概率是第二时频资源包括的资源数较多。
需要说明的是，针对上述情形2，在一种可能的实现方式中，若第一时域资源的结束符号的索引大于或等于第二时域资源的结束符号的索引，且第一UCI满足可以与第二UCI级联的条件时，第三时频资源为第一时频资源和第二时频资源中包括的资源元素较多的一个时频资源。否则，终端设备丢弃第二UCI或者丢弃第一UCI(假设已经在传输的UCI无法被取消)。其中，第一UCI与第二UCI级联的条件为：第一UCI中HARQ信息对应的接收PDSCH的最后一个符号到传输第二UCI的第一个符号之间的时间间隔可以完成该PDSCH生成对应的HARQ的时间。若第一UCI不满足与第二UCI级联的条件，即第一UCI中HARQ信息对应的PDSCH不满足可以和第二UCI级联的时间线限制，例如，第二UCI已经开始传输，而第一UCI对应的PDSCH还没有开始调度，则终端设备无法将第一UCI和第二UCI进行级联，因此，只能丢弃第二UCI或第一UCI(假设已经在传输的UCI无法被取消)。
方式二，第三时频资源为第一时频资源。
为了保证第一UCI发送至网络设备时满足时延要求，可始终将第一时频资源确定为第三时频资源。也就是说，终端设备可使用第一时频资源向网络设备发送压缩后的第二HARQ码本和第一UCI。相应地，网络设备可在第一时频资源上，接收来自终端设备的压缩后的第二HARQ码本和第一UCI。
本申请中，终端设备可将压缩后的第二HARQ码本和第一UCI进行级联。例如，第二HARQ码本级联(也可称为复接)于第一UCI之前。示例性地，结合上述图5a，压缩 后的第二HARQ码本为010，与第一UCI级联后为010110。再比如，第二HARQ码本级联于第一UCI之后，仍以图5a所示的压缩后的第二HARQ码本为010和第一UCI(110)为例，级联后为110010。结合图5b至图5d的过程相同，可参考图5a的介绍，此处不再一一赘述。进一步，可选地，终端设备可通过上述方式一(包括情形1和情形2)或方式二确定出的第三时频资源，向网络设备发送压缩后的第二HARQ码本和第一UCI。结合上述图5a，终端设备可通过第三时频资源向网络设备发送压缩后的第二HARQ码本和第一UCI(即010110)。
在一种可能的实现方式中，终端设备可根据压缩后的第二HARQ码本的比特数，确定承载压缩后的第二HARQ码本的第四时频资源。例如，终端设备可从压缩后的第二HARQ码本的比特数对应的PUCCH资源集合中重选新的时频资源，将该重选的新时频资源确定为第四时频资源。可以理解的是，不同的HARQ码本的比特数关联到不同的PUCCH资源集合。
在一种可能的实现方式中，网络设备可分别独立配置第一UCI对应的业务的多个第一PUCCH资源集合，以及第二UCI对应的业务的多个第二PUCCH资源集合。压缩后的第二HARQ码本与第一UCI级联之后对应的PUCCH资源集合可以为多个第一PUCCH资源集合。进一步，多个第一PUCCH资源集合中，PUCCH资源指示的索引相同时，多个第一PUCCH资源中分别对应的PUCCH资源的结束符号的索引相同。例如，HARQ比特数为1-10对应PUCCH资源集合1，HARQ比特数为11-20对应PUCCH资源集合2，索引1对应的PUCCH资源集合1中的PUCCH资源的结束符号的索引与对应的PUCCH资源集合2中的PUCCH资源的结束符号的索引相同。如此，当第一UCI与压缩后的第二HARQ级联后在第一PUCCH资源集合中重新选择新的资源，不会影响到第一UCI的时延。
方式三，第三时频资源可基于上述确定出的第四时频资源对应的时域资源与第一时频资源的第一时域资源是否重叠来确定。可分如下两种情形。
情形a，第四时频资源对应的时域资源与第一时频资源的第一时域资源部分重叠或完全重叠。
基于该情形a，在第一种可能的实现方式中，终端设备可将压缩后的第二HARQ码本与第一UCI进行级联，根据压缩后的第二HARQ码本和第一UCI的总比特数，确定第三时频资源。示例性地，基于不同的HARQ码本的比特数关联到不同的PUCCH资源集合，终端设备可从总比特数对应的PUCCH资源集合中重选新的时频资源，将该重选的新的时频资源确定为第三时频资源。通过方式三中的情形a，为压缩后的第二HARQ码本和第一UCI重新选择一个新的时频资源，作为第三时频资源。如此，既可以保证第一UCI的时延需求，又可增加传输第二HARQ码本的几率。其中，第二HARQ码本与第一UCI进行级联后可使用传输第一UCI的码率联合编码，关于压缩后的第二HARQ码本与第一UCI进行级联的方式可参见上述介绍，此处不再赘述。
需要说明的是，在一种可能的实现方式中，可先确定为压缩后的第二HARQ码本和第一UCI重新选择的新的时频资源的时域资源的结束符号的索引与第一时频资源的第一时域资源的结束符号的索引之间的关系。若该新的时频资源的结束符号的索引大于第一时域资源的结束符号的索引，则丢弃第二HARQ码本；若该新的时频资源的结束符号的索引小于或等于第一时域资源的结束符号的索引，则将该新的时频资源确定为第三时频资源。
基于该情形a，在第二种可能的实现方式中，终端设备可将第二HARQ码本直接丢弃， 在第一时频资源上向网络设备发送第一UCI。相应地，网络设备可在第一时频资源上，接收来自终端设备的第一UCI。
基于该情形a，在第三种可能的实现方式中，终端设备可确定出第四时频资源中与第一时频资源不重叠的时频资源，该不重叠的时频资源可称为第五时频资源。终端设备可在第五时频资源上向网络设备发送压缩后的第二HARQ码本，在第一时频资源上向网络设备发送第一UCI。相应地，网络设备可在第五时频资源上，接收来自终端设备的压缩后的第二HARQ码本，在第一时频资源上接收来自终端设备的第一UCI。进一步可选地，终端设备确定出第五时频资源后，可基于上述实现方式一、实现方式二、实现方式三、实现方式四、实现方式五或实现方式六，对压缩后的第二HARQ码本进行再次压缩，终端设备可在第五时频资源上向网络设备发送该再次压缩后的第二HARQ码本。
需要说明的是，在该第三种可能的实现方式中，第三时频资源包括第五时频资源和第一时频资源。另外，在另一种可能的实现方式中，终端设备可确定第四时频资源对应的时域资源与第一时域资源重叠的时域资源，若该重叠的时域资源所占第四时频资源对应的时域资源的比值小于或等于第三预设值，将第四时频资源中与第一时频资源不重叠的时频资源确定为第五时频资源。或者，也可以理解为，若第四时频资源对应的时域资源与第一时域资源不重叠的时域资源较大的时候，可通过第五时频资源发送压缩后的第二HARQ码本。若第四时频资源对应的时域资源与第一时域资源不重叠的时域资源较小的时候，即第四时频资源对应的时域资源与第一时域资源重叠的时域资源较大的时候，由于压缩后的第二HARQ码本被影响的程度较大，可直接将压缩后的第二HARQ码本丢弃，例如，第四时频资源对应的时域资源和第一时域资源完全重叠，则直接将压缩后第二HARQ码本丢弃。
情形b，第四时频资源对应的时域资源与第一时频资源的第一时域资源不重叠。
基于该情形b，终端设备可在第一时频资源上向网络设备发送第一UCI，在第四时频资源上向网络设备发送压缩后的第二HARQ码本。相应地，网络设备可在第四时频资源上，接收来自终端设备的压缩后的第二HARQ码本，在第一时频资源上接收来自终端设备的第一UCI。在该情形b中，第三时频资源包括第一时频资源和第四时频资源。
需要说明的是，若是基于上述实现方式六对第二HARQ码本进行压缩，由于基于TB的第二HARQ码本的比特数较基于CBG的第二HARQ码本的比特数小很多，因此，确定出的第四时频资源也较小。如此，第四时频资源对应的时域资源与第一时频资源的第一时域资源重叠的概率是较小的。
方式四，直接根据压缩后的第二HARQ码本和第一UCI级联后的总比特数，确定新的时频资源，将该新的时频资源确定为第三时频资源。
在一种可能的实现方式中，直接根据压缩后的第二HARQ码本和第一UCI级联后的总比特数，确定新的时频资源，若该新的时域资源的结束符号的索引大于第一时域资源的结束符号的索引，则丢弃压缩后的第二HARQ码本；若该新的时域资源的结束符号的索引小于或等于第一时域资源的结束符号的索引，则将该新的时频资源确定为第三时频资源。
该实现方式四，具体可参见上述方式三的情形a中的第一种可能的实现方式的介绍，此处不再赘述。
方式五，第三时频资源基于第一时频资源的第一时域资源与第二时频资源的第二时域资源部分重叠的情况来确定。
基于该方式五，终端设备可在第六时频资源上向网络设备发送压缩后的第二HARQ码 本，在第一时频资源上向网络设备发送第一UCI，其中，第六时频资源为第二时频资源中与第一时频资源不重叠的时频资源。相应地，网络设备可在第六时频资源上，接收来自终端设备的压缩后的第二HARQ码本，在第一时频资源上接收来自终端设备的第一UCI。也就是说，当第一时域资源与第二时域资源部分重叠时，可将第二时频资源中与第一时频资源重叠的时频资源丢弃，在丢弃后剩余的时频资源上发送压缩后的第二HARQ码本。在该方式五中，第三时频资源包括第六时频资源和第一时频资源。
需要说明的是，终端设备可确定第二时域资源与第一时域资源重叠的时域资源与第二时域资源的比值，若该比值小于或等于第一预设值，则可将第二时频资源中与第一时频资源不重叠的时频资源确定为第六时频资源。若第一时域资源与第二时域资源重叠的较大时，第二HARQ码本被影响的程度较大，可直接将第二HARQ码本丢弃，不再执行压缩第二HARQ码本的过程。
还需要说明的是，上述第一预设值和第三预设可以是经验值、历史数据统计值、或典型值、或者是网络设备通过无线资源控制(radio resource control，RRC)、媒体接入控制(medium access control，MAC)、主系统信息块(master information block，MIB)、系统信息块(system information block，SIB)、DCI等信令中的任一种配置的值。第一预设值和第三预设值可以相同，也可以不相同。如果该第一预设值和第三预设值为经验值或典型值，则可在设置后可以是固定不变的，例如可均设置为0.5。或者，第一预设值和第三预设值也可以是协议所规定的值。
上述五种方式只是举例，本申请并不限制终端设备通过哪种方式向网络设备发送压缩后的第二HARQ和第一UCI。选择如上的哪种方式来发送，可以通过协议规定，也可以是网络设备指示。另外，发送第一UCI和压缩后的第二HARQ时，第一UCI的码率一般均为传输的最大码率。
实现方式1，网络设备接收到的被压缩的第二HARQ码本是基于上述实现方式一得到的。
在该实现方式1中，网络设备可从被压缩的第二HARQ码本的第一个比特开始，将L比特中的前L-1个比特中的每一个比特的HARQ信息解压缩为M比特的HARQ信息，将L比特中的最后一个比特解压缩为S-M*(L-1)比特的HARQ信息，其中，

表示向上取整。
进一步，可选地，网络设备可将取值为1的一个比特解压缩为M个取值为1的比特，将取值为0的一个比特解压缩为M个取值为0的比特。进一步，将取值为1的最后一个比特解压缩为S-M*(L-1)个取值为1的比特，将取值为0的最后一个比特解压缩为S-M*(L-1)个取值为0的比特。
结合上述图5a，M＝2，被压缩的第二HARQ码本为010，解压缩后可确定被压缩的每1比特的HARQ信息对应第二HARQ码本的2比特的HARQ信息，进一步，0表示NACK，1表示ACK，因此，可确定出第二HARQ码本中第一个比特、第二个比特、第五个比特和第六个比特分别对应的PDSCH需要重传，第三个比特和第四个比特分别对应的PDSCH不需要再重传。在一种可能的实现方式中，网络设备解压缩可得到第二HARQ码本为001100。
实现方式2，网络设备接收到的被压缩的第二HARQ码本是基于上述实现方式二得到的。
在该实现方式2中，网络设备可从被压缩的第二HARQ码本的第一个比特开始，将L 比特中的前L-1个比特中的每一个比特的HARQ信息解压缩为2 N比特的HARQ信息，将L比特中的最后一个比特解压缩为S-2 N*(L-1)比特的HARQ信息，其中，

表示向上取整。
进一步，可选地，网络设备可将取值为1的一个比特解压缩为2 N个取值为1的比特，将取值为0的一个比特解压缩为2 N个取值为0的比特。进一步，将取值为1的最后一个比特解压缩为S-2 N*(L-1)个取值为1的比特，将取值为0的最后一个比特解压缩为S-2 N*(L-1)个取值为0的比特。
结合上述图5b，N＝1，被压缩的第二HARQ码本为010，解压缩后可确定被压缩的每1比特的HARQ信息对应第二HARQ码本的2 N＝2比特的HARQ信息，0表示NACK，1表示ACK，可确定出第二HARQ码本中第一个比特、第二个比特、第五个比特和第六个比特分别对应的PDSCH需要重传，第三个比特和第四个比特分别对应的PDSCH不需要再重传。在一种可能的实现方式中，网络设备解压缩可得到第二HARQ码本为001100。
实现方式3，网络设备接收到的被压缩的第二HARQ码本是基于上述实现方式三得到的。
在该实现方式3中，网络设备可将L比特的被压缩的第二HARQ码本解码为S比特。
实现方式4，网络设备接收到的被压缩的第二HARQ码本是基于上述实现方式四得到的。
在该实现方式4中，网络设备可从被压缩的第二HARQ码本的第一个比特开始，将L比特中的前L-1个比特中的每一个比特的HARQ信息解压缩为1比特的HARQ信息，将L比特中的最后一个比特解压缩为(S-L+1)比特的HARQ信息。
进一步，可选地，网络设备可将取值为1的最后一个比特解压缩为(S-L+1)个取值为1的比特，将取值为0的最后一个比特解压缩为(S-L+1)个取值为0的比特。
实现方式5，网络设备接收到的被压缩的第二HARQ码本是基于上述实现方式五得到的。
在该实现方式5中，网络设备可直接确定L比特中每一比特的HARQ信息。
实现方式6，网络设备接收到的被压缩的第二HARQ码本是基于上述实现方式六得到的。
基于该实现方式6，在一种可能的实现方式中，第二HARQ码本为基于CBG的HARQ码本。网络设备可确定基于CBG的第二HARQ码本被修改为基于TB的第二HARQ码本。进一步，可选地，网络设备可将修改为基于TB的第二HARQ码本中取值为1的一个比特解压缩为8个取值为1的比特，将取值为0的一个比特解压缩为8个取值为0的比特。
在另一种可能的实现方式中，第二HARQ码本为基于CBG和基于TB的HARQ码本。网络设备可确定基于CBG和基于TB的第二HARQ码本被修改为基于TB的第二HARQ码本。进一步，可选地，网络设备可将修改为基于TB的第二HARQ码本中取值为1的一个比特解压缩为8个取值为1的比特，将取值为0的一个比特解压缩为8个取值为0的比特。
需要说明的是，在一种可能的实现方式中，若上述压缩方式是终端设备自行选择的，终端设备可向网络设备指示出对第二HARQ码本的压缩方式，可以通过显示的方式指示，或者也可以通过隐式的方式指示，本申请对此不做限定。
在一种可能的实现方式中，可通过上述实现方式一、实现方式二、实现方式三、实现 方式四和实现方式五对第二HARQ码本的压缩方式，通过上述方式一、方式二确定的第三时频资源发送压缩后的第二HARQ码本和第一UCI；实现方式六对第二HARQ码本的压缩方式，可通过方式三、方式四和方式五确定的第三时频资源发送压缩后的第二HARQ码本和第一UCI。
在另一种可能的实现方式中，可通过实现方式一、实现方式二、实现方式三、实现方式四和实现方式五对第二HARQ码本的压缩方式，通过上述方式三、方式四和方式五确定的第三时频资源发送压缩后的第二HARQ码本和第一UCI。
在又一种可能的实现方式中，可以通过上述实现方式六对第二HARQ码本进行压缩，之后再通过上述实现方式一、实现方式二、实现方式三、实现方式四或实现方式五中的任一种再压缩，通过方式一、方式二和方式五确定的第三时频资源发送压缩后的第二HARQ码本和第一UCI。
需要说明的是，本申请对压缩第二HARQ码本的实现方式与发送压缩后的第二HARQ码本和第一UCI的第三时频资源的确定方式的组合不做限定，如上给出的仅是三种可能的示例。
在上述实施例中，在一种可能的实现方式中，第二HARQ码本的比特数大于第二预设值。也就是说，当第二HARQ码本的比特数较小时，对下行吞吐量的影响较小，可直接丢弃第二HARQ码本。需要说明的是，第二预设值可以是经验值、历史数据统计值、或典型值、或者是网络设备使用RRC、MAC、MIB、SIB、DCI等信令中的任一种配置的值。
本申请中，第一UCI可为URLLC业务对应的UCI，第二UCI可为eMBB对应的UCI。
