本申请主张在2018年12月28日在中国提交的中国专利申请号No.201811626728.X的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，特别涉及一种上行控制信息的传输方法及终端。
背景技术
新空口(New Radio，NR)R15基于码块组(code block group，CBG)的混合自动重传请求确认(Hybrid Automatic Repeat reQuest ACK，HARQ-ACK)反馈是每个服务小区(serving cell)配置的，一旦配置了PDSCH-CodeBlockGroupTransmission，用户设备(User Equipment，UE)就会按照基于CBG的方式反馈HARQ-ACK(除了PDSCH是下行控制信息(Downlink Control Information，DCI)format 0-0调度的以外)，即使当PDSCH是DCI format 0_0调度时，UE会回退到基于传输块(transmission block，TB)的HARQ-ACK(TB-based HARQ-ACK)，但也需要通过重复的方式反馈等于CBG-based HARQ-ACK的比特数。
需要说明的是，CBG based HARQ-ACK主要适用于TB比较大且有窄带干扰的情况下，且需要反馈较多的HARQ-ACK比特数，降低反馈信息接收性能。当UE支持不同的业务类型时，不同的业务类型可能适用于不同类型的PDSCH传输(TB-based/CBG-based PDSCH传输)，一个服务小区上可以调度不同的业务，因此需要考虑基于CBG的PDSCH传输的具体配置形式或终端反馈HARQ-ACK的方式，相关技术中并没有相关的定义，无法满足不同业务的需求；同时，当不同类型的HARQ-ACK同时进行反馈时，相关技术中的反馈方式会造成传输的比特较多，也无法保证业务传输可靠性。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图及具体实施例对本公开进行详细描述。
在进行本公开的一些实施例的说明时，首先对下面描述中所用到的一些概念进行解释说明。
一、NR中的不同业务需求
与以往的移动通信系统相比，未来第五代(5Generation，5G)移动通信系统需要适应更加多样化的场景和业务需求。5G的主要场景包括：移动宽带增强(enhanced Mobile BroadBand，eMBB)，超高可靠超低时延通信(Ultra-Reliable and Low Latency Communications，URLLC)，大规模物联网(massive Machine Type of Communication，mMTC)，这些场景对系统提出了高可靠，低时延，大带宽，广覆盖等要求。对于支持URLLC低时延高可靠业务的用户设备(User Equipment，UE)，UE既支持URLLC低时延高可靠业务，同时支持大容量高速率的eMBB业务。不同业务类型的可靠性要求主要体现在不同的传输带宽、目标误块率(target BLER)和延时(latency)要 求。
二、基于传输块(TB-based)/基于码块组(CBG-based)的混合自动重传请求确认(Hybrid Automatic Repeat reQuest ACK，HARQ-ACK)(即TB-based HARQ-ACK/CBG-based HARQ-ACK)
物理下行共享信道(Physical Downlink Shared Channel，PDSCH)传输中，每个PDSCH可以是一个或两个TB组成。新空口(New Radio，NR)R15中支持两种类型的HARQ-ACK反馈，TB-based HARQ-ACK和CBG-based HARQ-ACK。TB-based HARQ-ACK是每个TB反馈1比特HARQ ACK/NACK，CBG-based HARQ-ACK是将每个TB分成若干个码块(code block，CB)，再将几个CB组成一个码块组(code block group，CBG)，每个CBG反馈1比特HARQ ACK/NACK。CBG-based HARQ-ACK主要适用于TB比较大的情况，将一个TB分成若干个CBG，基站基于每个CBG的HARQ-ACK反馈，只对反馈NACK的CBG重传，而不需要将整个TB重传，可以减小重传开销，提高系统效率。在UE侧，UE具体采用TB-based(每个TB反馈1比特HARQ ACK/NACK)还是CBG-based反馈(每个TB反馈多比特HARQ ACK/NACK)是由无线资源控制(Radio Resource Control，RRC)参数PDSCH-CodeBlockGroupTransmission配置，即如果UE配置了参数PDSCH-CodeBlockGroupTransmission，除了PDSCH是下行控制信息(Downlink Control Information，DCI)format 0_0调度的情况，UE按照CBG-based HARQ-ACK反馈，当PDSCH是DCI format 0_0调度的情况，UE将从CBG-based HARQ-ACK回退到TB-based HARQ-ACK反馈，但是UE反馈的HARQ-ACK的比特数仍然是等于基于CBG反馈时的比特数N(等于RRC配置的最大CBG数目)，TB-based HARQ-ACK重复成N比特。参数PDSCH-CodeBlockGroupTransmission是每个服务小区(serving cell)配置的，即在载波聚合(Carrier Aggregation，CA)的情况下，UE可以有些服务小区是CBG-based HARQ-ACK，有些服务小区是TB-based HARQ-ACK。
在R16中，UE可以同时支持URLLC和eMBB业务，URLLC和eMBB PDSCH可以在一个服务小区上传输。CBG-based HARQ-ACK主要是适用于TB比较大的情况，且需要反馈的HARQ-ACK比特数较多，在相同PUCCH 资源上传输时，可靠性就会下降。因此CBG-based HARQ-ACK并不适合URLLC。
当eMBB的CBG-based和URLLC的TB-based在一个信道反馈时(URLLC和eMBB采用不同的HARQ-ACK codebook在不同的PUCCH资源上传输，两个PUCCH信道冲突的情况下，两个PUCCH上的HARQ-ACK信息复用在一个PUCCH资源上，或URLLC和eMBB采用一个HARQ-ACK codebook反馈，在一个PUCCH上反馈HARQ-ACK)，由于eMBB的CBG-based的HARQ-ACK反馈的比特数较多，可能会降低URLLC的HARQ-ACK反馈的可靠性。因此还需要考虑不同业务类型时TB-based HARQ-ACK和CBG-based HARQ-ACK复用的问题。
基于上述考虑，如图1所示，本公开的一些实施例提供一种上行控制信息的传输方法，应用于终端，包括：
步骤101，根据是否配置基于码块组CBG的物理下行共享信道PDSCH传输，确定反馈每个PDSCH对应的混合自动重传请求应答HARQ-ACK所采用的类型；
需要说明的是，基于CBG的PDSCH传输是基于服务小区、控制资源集或搜索空间配置的；服务小区、控制资源集或搜索空间可以看成是基于CBG的PDSCH传输的配置粒度，该配置粒度通过协议进行规范，网络设备采用相应的高层信令配置具体的PDSCH传输形式(TB-based/CBG-based PDSCH传输)给终端，终端可以从协议约定中得知具体采用哪种配置方式并按照配置方式理解相应的高层配置信令。
步骤102，根据每个PDSCH对应的HARQ-ACK所采用的类型，进行至少一个PDSCH对应的HARQ-ACK的传输；
需要说明的是，所述每个PDSCH对应的HARQ-ACK所采用的类型包括：基于CBG的HARQ-ACK反馈方式或基于传输块(TB)的HARQ-ACK反馈方式。
具体地，终端传输的PDSCH对应的HARQ-ACK为HARQ的应答确认(ACK)或HARQ的非应答确认(NACK)
通过根据是否配置基于CBG的PDSCH传输来确定每个PDSCH对应的 HARQ-ACK的类型，以此可以保证每个PDSCH对应的HARQ-ACK的传输尽可能满足终端的业务需求，提高了传输的可靠性。
因基于CBG的PDSCH传输依据的配置粒度不同，终端确定反馈每个PDSCH对应的HARQ-ACK所采用的类型的具体实现方式也会不同，下面从不同配置粒度的角度，对步骤101的具体实现进行说明如下。
一、所述基于CBG的PDSCH传输是基于服务小区配置
具体地，步骤101的实现方式为：
当所述PDSCH对应的服务小区配置基于CBG的PDSCH传输时，根据调度所述PDSCH的物理下行控制信道(Physical Downlink Control Channel，PDCCH)的第一参数，确定反馈每个PDSCH对应的HARQ-ACK所采用的类型。
需要说明的是，网络设备会通过RRC信令通知终端所述PDSCH对应的服务小区是否配置基于CBG的PDSCH传输，当终端得知PDSCH对应的服务小区配置基于CBG的PDSCH传输时，终端会根据第一参数，确定反馈每个PDSCH对应的HARQ-ACK所采用的类型；而当PDSCH对应的服务小区未配置基于CBG的PDSCH传输，终端会按照基于TB的HARQ-ACK反馈方式进行PDSCH对应的HARQ-ACK传输。
需要说明的是，所述第一参数，包括以下信息中的至少一项：
A11、PDCCH所承载的下行控制信息(DCI)格式；
A12、PDCCH所在搜索空间或控制资源集；
A13、PDCCH所使用的无线网络临时标识(Radio Network Temporary Identifier，RNTI)；
A14、PDCCH所承载的DCI中的指示信息；
A15、PDCCH对应的调制与编码策略(Modulation and Coding Scheme，MCS)表；
A16、PDCCH所对应的加扰比特信息；
A17、PDCCH中携带的资源指示信息；
需要说明的是，所述资源指示信息用于指示数据或者控制信息传输的资源；具体地，所述资源包括：时域资源和/或频域资源；
A18、PDCCH中携带的用于指示数据或者控制信息传输的导频映射类型信息。
需要说明的是，终端按照第一参数的具体内容，进行反馈HARQ-ACK所采用的类型的确定，例如，当第一参数为RNTI时，若终端调度所述PDSCH的PDCCH使用的是小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)，则终端确定反馈PDSCH对应的HARQ-ACK所采用的类型为基于CBG的HARQ-ACK反馈方式，终端会按照基于CBG的HARQ-ACK反馈方式进行HARQ-ACK的反馈；若终端调度所述PDSCH的PDCCH使用的是MCS小区无线网络临时标识(Modulation and Coding Scheme-Cell Radio Network Temporary Identifier，MCS-C-RNTI)，则终端确定反馈PDSCH对应的HARQ-ACK所采用的类型为基于TB的HARQ-ACK反馈方式，终端会按照基于TB的HARQ-ACK反馈方式进行HARQ-ACK的反馈。
二、所述基于CBG的PDSCH传输是基于控制资源集或搜索空间配置
具体地，步骤101的实现方式为：
当调度所述PDSCH的物理下行控制信道PDCCH所对应的控制资源集或搜索空间配置了基于CBG的PDSCH传输，确定反馈PDSCH对应的HARQ-ACK所采用的类型为基于CBG的HARQ-ACK反馈方式；或者
当调度所述PDSCH的物理下行控制信道PDCCH所对应的控制资源集或搜索空间未配置基于CBG的PDSCH传输，确定反馈PDSCH对应的HARQ-ACK所采用的类型为基于TB的HARQ-ACK反馈方式。
需要说明的是，在此种情况下，网络设备会通过RRC信令通知终端所述PDSCH对应的控制资源集或搜索空间是否配置基于CBG的PDSCH传输；终端会根据调度所述PDSCH的PDCCH所对应的控制资源集或搜索空间是否配置了基于CBG的PDSCH传输，直接确定反馈PDSCH对应的HARQ-ACK所采用的类型为基于TB的HARQ-ACK反馈方式还是基于CBG的HARQ-ACK反馈方式。
还需要说明的是，在终端进行HARQ-ACK反馈之前，首选需要网络设备发送PDCCH给终端，该PDCCH用于调度PDSCH或激活半静态调度 SPS(Semi-Persistent Scheduling)PDSCH，然后终端根据对接收到的PDSCH的解码进行HARQ-ACK的反馈。当传输的HARQ-ACK包括至少两个PDSCH对应的HARQ-ACK，且该至少两个PDSCH对应的HARQ-ACK中包括：基于CBG的第一HARQ-ACK和基于TB的第二HARQ-ACK时，步骤102的具体实现方式为：
步骤1021，若所述第一HARQ-ACK和所述第二HARQ-ACK在同一个信道上传输，将所述第一HARQ-ACK进行回退，得到基于TB的第三HARQ-ACK；
需要说明的是，进行第一HARQ-ACK的回退指的是，将基于CBG的第一HARQ-ACK回退到基于TB的HARQ-ACK，进行回退后，所述第三HARQ-ACK的比特个数等于所述第一HARQ-ACK对应的PDSCH所对应TB的个数，例如对一个TB对应的所有CBG的HARQ-ACK进行逻辑与操作得到1比特，此种方式，可以有效减少反馈的比特个数。
步骤1022，将所述第三HARQ-ACK和所述第二HARQ-ACK复用在第一资源上传输。
需要说明的是，在非CA情况下，所述TB-based/CBG-based HARQ-ACK可以是对同一个服务小区(serving cell)上的不同PDSCH的反馈；
在CA情况下，所述TB-based/CBG-based HARQ-ACK可以是对同一个serving cell上的不同PDSCH的反馈；
在CA情况下，所述TB-based/CBG-based HARQ-ACK可以是对不同服务小区上的不同PDSCH的反馈(此时，CBG-based HARQ-ACK的配置以及反馈都可以按照R15方式，网络设备可以在不同的服务小区上调度不同的业务数据，这样在调度业务1小区上不配置基于CBG的PDSCH传输，在业务2小区上配置基于CBG的PDSCH传输，然后不同的服务小区上的PDSCH都在一个PUCCH上反馈)。
进一步，还需要说明的是，所述第一资源可以采用如下方式中的一种实现：
方式一、所述第一资源为目标HARQ-ACK所在的PUCCH资源；
具体地，所述目标HARQ-ACK为：所述第一HARQ-ACK或所述第二 HARQ-ACK；即，所述第一资源可以为所述第一HARQ-ACK所在的PUCCH资源；或者，所述第一资源可以为所述第二HARQ-ACK所在的PUCCH资源。
方式二、所述第一资源为目标资源；
具体地，所述目标资源可以不同于所述第二HARQ-ACK所在的PUCCH资源和所述第一HARQ-ACK所在的PUCCH资源，即所述第一资源为除所述第一HARQ-ACK所在的PUCCH资源和所述第二HARQ-ACK所在的PUCCH资源之外的其他资源。
具体地，该目标资源的获取方式为：
基于反馈的HARQ-ACK的比特个数和第一DCI中的PUCCH资源指示确定；
其中，所述反馈的HARQ-ACK的比特个数为所述第二HARQ-ACK和所述第三HARQ-ACK的比特个数之和；所述第一DCI为反馈的PDSCH对应的PDCCH排序中最后一个PDCCH承载的DCI。
具体地，PDCCH的排序规则在协议中规范，这里并不做限制。例如NR R15中PDCCH排序规则为：先按照PDCCH侦听时机(monitoring occasion)从前到后的顺序进行PDCCH排序，若PDCCH monitoring occasion相同，则按照服务小区索引(serving cell index)从小到大的顺序将PDCCH monitoring occasion相同的PDCCH进行排序。
例如，当两个HARQ-ACK PUCCH冲突时，终端将CBG-based HARQ-ACK回退到TB-based HARQ-ACK方式，且与TB-based HARQ-ACK复用在TB-based HARQ-ACK PUCCH信道资源上。
例如，当两个HARQ-ACK PUCCH冲突时，终端将CBG-based HARQ-ACK回退到TB-based HARQ-ACK方式，且与TB-based HARQ-ACK复用在一个PUCCH信道资源上，该信道资源可以是基于反馈的HARQ-ACK的比特数和最后一个DCI(反馈的所有PDSCH对应的PDCCH排序中最后一个PDCCH承载的DCI)中的PRI(PUCCH resource indicator)确定的。
例如，两个HARQ-ACK PUCCH与一个PUSCH冲突，终端将CBG-based HARQ-ACK回退到TB-based HARQ-ACK方式，且与TB-based HARQ-ACK复用在该PUSCH上。
例如，当某个PUCCH上反馈的PDSCH对应的PDCCH既有C-RNTI加扰的又有MCS-C-RNTI时，UE将CBG-based HARQ-ACK回退到TB-based HARQ-ACK方式，且与TB-based HARQ-ACK复用在一个PUCCH信道资源上，该PUCCH信道资源可以是基于反馈的HARQ-ACK的比特数和最后一个DCI(反馈的所有PDSCH对应的PDCCH排序中最后一个PDCCH承载的DCI)中的PRI(PUCCH resource indicator)确定的。
需要说明的是，这里的CBG-based HARQ-ACK回退到TB-based HARQ-ACK，是指UE按照TB方式反馈HARQ-ACK，反馈HARQ-ACK的比特数与PDSCH的TB数一样。
本公开的一些实施例，通过根据是否配置基于CBG的PDSCH传输，确定反馈PDSCH对应的HARQ-ACK所采用的类型，并依据反馈PDSCH对应的HARQ-ACK所采用的类型进行HARQ-ACK传输，以此可以保证HARQ-ACK的传输能满足业务需求；同时当不同类型的HARQ-ACK在同一信道上传输时，通过减少比特个数的方式将不同类型的HARQ-ACK复用在相同的信道上传输，以此可以保证不同业务的HARQ-ACK传输的可靠性，进而保证了通信可靠性。
需要说明的是，本公开的一些实施例中提到的HARQ-ACK表示对下行传输的HARQ-ACK，可以是对PDCCH调度的PDSCH的反馈，或半静态调度的PDSCH(SPS PDSCH)的反馈，或释放(release)SPS PDSCH的PDCCH的反馈。
如图2所示，本公开的一些实施例提供一种终端200，包括：
确定模块201，用于根据是否配置基于码块组CBG的物理下行共享信道PDSCH传输，确定反馈每个PDSCH对应的混合自动重传请求应答HARQ-ACK所采用的类型；

其中，所述第三HARQ-ACK的比特个数等于所述第一HARQ-ACK对应的PDSCH所对应TB的个数。
具体地，所述第一资源为目标HARQ-ACK所在的PUCCH资源，或者
所述第一资源为目标资源；
其中，所述目标HARQ-ACK为：所述第一HARQ-ACK或所述第二HARQ-ACK；
所述目标资源不同于所述第二HARQ-ACK所在的PUCCH资源和所述第一HARQ-ACK所在的PUCCH资源。
进一步地，当所述第一资源为目标资源时，所述第一资源的获取方式为：
