相关申请的交叉引用
本申请基于申请号为201711230885.4、申请日为2017年11月29日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及通信领域但不限于通信领域，尤其涉及一种信息解码、码本处理方法及装置、存储介质，处理器。
背景技术
在新型无线电(New Radio，简称NR)中，存在不同的子载波间隔(subcarrier spacing，简称SCS)，例如典型的SCS有15KHz，30KHz，60KHz和120KHz，这些不同的SCS将导致一个调度单元的时长不同，例如，一个调度单元包含14个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，一个15KHz子载波间隔的载波(CC)的调度单元长度为N，那么一个30KHz SCS的调度单元长度为N/2，一个60Khz SCS的调度单元长度为N/4，一个120Khz SCS的调度单元长度为N/8。
在NR中也有载波聚合的工作模式，但是如果不同SCS的载波通过载波聚合的方式为一个UE传输数据，那么UE该如何对于这些不同SCS的载波中的数据反馈混合自动重传请求-确认信息(Hybrid Automatic Repeat request Acknowledgement，简称HARQ-ACKs)，尤其是这些不同SCS的载波中调度有多个物理下行共享信道(Physical Downlink Shared Channel，简 称PDSCH)(或传输块(Transport Block，简称TB)，以下以传输块为例)，且要求这些TBs在一个载波的一个物理上行控制信道(Physical Uplink Control Channel，简称PUCCH)组内(即这些TB的HARQ-ACK要求复用在一起反馈)进行反馈HARQ-ACKs时，UE如何对这些不同SCS的载波中的数据反馈HARQ-ACKs。
而在NR中被聚合的载波的SCS不同(或者说被聚合的载波的调度单元时长不同)时，如果多个聚合的CC中的TBs的HARQ-ACK被要求复用在一起，并不能高效的保证码本的大小在基站和UE之间理解一致。
针对相关技术中的上述问题，目前尚未提出有效的解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本申请。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第 一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
图1是相关技术中不同SCS或不同调度单元时长的载波被聚合为一个UE传输数据的载波示意图，在图1中，UE配置了6个载波，CC#0和CC#4的SCS是15KHz，调度单元的长度最长；CC#3和CC#5的SCS是30KHz，调度单元的长度居中；CC#1和CC#2的SCS是60KHz，调度单元长度最短。
按照LTE中的方式，当UE配置的载波数量大于或等于5个时，将使用下行分配索引(Downlink Assignment index，简称DAI)机制帮助UE发现丢失的TB，这种DAI机制能帮助UE发现丢失的TB，从而在形成HARQ-ACK时，也要为丢失的TB形成对应的HARQ-ACK，这样就使得多个TB的HARQ-ACK在复用时对应的总的比特数(即反馈的HARQ-ACK比特数，称为码本大小)在基站和UE侧理解一致，从使得多个TB的HARQ-ACK复用能够顺利进行。
DAI机制一个关键是在末尾的DAI接收中，要保证至少接收到一个DAI信息，如果得到保证，那么DAI机制将不能可靠的反应出所有的TB。所以，在LTE中，DAI是通过DCI承载的，且认为UE检测4个DCI信息时至少能正确接收一次。但是在LTE中所有聚合的载波的SCS都是一样，这将使得问题比较简单。
而在NR中被聚合的载波的SCS不同(或者说被聚合的载波的调度单元时长不同)时，如果多个聚合的CC中的TBs的HARQ-ACK被要求复用在一起，如何高效的保证码本的大小在基站和UE之间理解一致，是本申请实施例所要解决的问题。

在一些实施例中，本实施例中的具体示例可以参考上述实施例及可选实施方式中所描述的示例，本实施例在此不再赘述。
为了更好地理解本申请，以下结合优选的实施例对本申请做进一步解释。
在本次调度的多个TB(多个TB的HARQ-ACK被要求复用)的末尾(相当于上述实施例中的最后一个TB)的调度时机处或末尾的调度单元内，利用mini-slot机制来提供承载DAI的DCI发送机会。该方式可以应用于多个载波，也可以为单个载波使用。承载DAI的mini-slot可以不承载用户数据，也就是说可以只发送承载DAI的DCI，以增加承载DAI的DCI在本次调度末尾的接收的可靠性。
在为UE配置的多个具有不同SCS的载波中，在每个载波中为UE发送了PDSCH或TB，这些PDSCH或TB对应的HARQ-ACK被要求复用在一起反馈。为了防止UE丢失部分PDSCH或TB，引入了DAI机制，由于DAI是通过DCI承载的，DCI丢失的概率为1％，又为了保证DAI接收的可靠性，建议采用下面的方式发送DAI。这里假设，UE检测4次(4次只是一个例子，次数可以根据要求调整)DCI，至少会正确检测到一次，即有4次DCI检测时，可以保证至少一次DCI被检测到。这样承载在DCI中的总共DAI(total DAI)将将告诉UE本次需要反馈的码本大小。在同一时刻，基站在不同CC中发送了TB时，将通过总共DAI标记截止本次发送后，UE需要反馈的码本大小。DAI机制可以参考LTE 36.213协议中的描述。
在被要求的多个PDSCH或TB结束的调度单元处通过mini-slot发送承载DAI的信息。具体包括：
基站在所述多个载波中，被传输PDSCH或TB的载波中具有SCS最大的载波(也就是调度单元时长最小的)(相当于上述实施例中的承载最后一个PDSCH或TB的载波)的末尾传输处，在其他载波(相当于上述实施例 中的第一指定载波)中通过mini-slot中的DCI来承载DAI信息。其他载波的数量满足：其他载波数量+所述末尾传输处载波数之和等于或大于要求的数量，例如要求数量为4次，即要求数量为至少多少次的DCI检测中能正确检测到一次DCI。其他载波可以是承载TB的载波，例如图7中的载波CC#0，也可以是非承载TB的CC#3，其中，图7是根据本实施例提供的通过mini-slot在调度的末尾承载DAI信息的示意图。
例如，在图7中，被示意的TB的HARQ-ACK都被要求复用在一起传输，此时传输的末尾为CC#2的最后一个TB，即该TB对应的DCI是本次多个TB中发送最晚的一个。此时以该DCI发送时机出调度mini-slot，例如在CC#0，CC#4和CC#5中调度了mini-slot，通过mini-slot的DCI承载DAI信息，再加上CC#1中的DCI承载的DAI信息，那么共有4个DCI承载了DAI在本次调度的末尾。这样，UE将接受到至少一次DCI，从而获得其中的DAI信息。此时末尾的这4个DCI中承载的counter DAI是逐次累加的(如果有，因为如果是上行授权的DCI的话，可以只有total DAI)，total DAI是相同的。
Mini-slot是NR中的一种slot结构，它在调度单元中出现的位置是灵活的，且带有自己的DCI。
对于为UE配置的多个载波，这些载波有不同的SCS或不同的调度单元时长，一种方式是，按照参考载波的调度单元时长，将该调度单元时长对应的其他载波的多个调度单元设置为一个调度单元组，这个调度单元组使用固定码本(例如每个调度单元对应n个比特的HARQ-ACK，或者一个调度单元组整体使用一个比特，组内调度单元之间采用HARQ-ACK捆绑机制)。参考载波能被基站配置，然后通知UE。参考载波也可以是基站和UE事先约定的。这种方式将调度单元时长较短的分组处理，每组的调度单元时长与参考载波调度单元时长相同，且每组调度单元码本固定，这样，多 个载波能被视作具有相同“调度单元时长”的多个载波来处理。
在多个载波中确定一个参考载波，按照参考载波(相当于上述实施例中的第一参考载波)的一个(或多个)的调度单元(即参考单元，相当于上述实施例中的第一指定调度单元)对应将其他载波的多个调度单元分为一组，即在其他载波中，将与一个参考单元对齐的多个时长较短的调度单元分为一组，记为一个固定码本(调度单元分为一组只是为了描述方便，其本质是参考载波的一个调度单元对应的其他载波的多个调度单元采用固定码本)。参考载波可以是SCS最小的载波，或调度单元时长最长的载波。参考载波能被按照约定规则默认得到，也可以是基站配置给UE的。如果是约定规则默认，可以约定为配置给UE的(或可以约定为UE传输数据的)多个载波中SCS最小的载波。图8是根据本申请实施例提供的按照参考载波的调度单元时长对其他载波的调度单元进行分组的示意图。
例如，在图8中，共有3种不同的SCS的载波，也对应着有3种不同长度的调度单元。例如CC#0或CC#4作为参考载波，它的一个调度单元作为参考单元。将CC#2和CC#3中与一个参考单元对齐的4个调度单元分为一组，作为一个固定码本，例如固定反馈HARQ-ACK为4bit，每个调度单元中的数据对应一个比特，只要这4个调度单元中有一个调度单元传输了数据，那么也需要反馈4bit，其他3个调度单元可以反馈填充比特例如填充0。如果这4个调度单元中均未传输数据，那么如果是动态码本时，则不用反馈HARQ-ACK，如果是固定码本时，则也仍旧需要反馈4比特HARQ-ACK。
参考单元对应的载波能被基站配置给UE。这样就可以根据参考载波中的调度单元来对其他载波的调度单元进行划分。其他载波中的调度单元能被看做是进行了分组，每组采用固定码本。这样，等效于不同SCS的载波中调度单元(其他载波按照调度单元组)是对齐的。从而，将多个不同SCS 的载波转化为可以按照具有相同SCS的载波来多个TB时的码本大小确定问题。此时只是需要对于每个调度单元组采用约定好的固定码本即可。
也可以选择CC#3作为参考载波，然后将CC#1和CC#2的2个调度单元分为一组，每组有2个调度单元，对应的反馈比特为2比特。
本实施例基于迁一个实施例中的方式应用于本次调度的多个TB的末尾的调度单元中。从而减少开销，提升灵活性。
将前一个实施例中的按照参考载波的调度单元时长对其他载波的调度单元进行分组的规则只应用于本次多个PDSCH/TB对应HARQ-ACK复用在一起的末尾的调度单元(相当于上述实施例中的从开始调度所述多个PDSCH或TB的时机处到结束调度所述多个PDSCH或TB的时机的时间段内，所述第一参考载波中的最后一个调度单元)中。
参考载波(相当于上述实施例中的第一参考载波)的确定可如前述任意实施例。末尾的调度单元，即本次调度的多个PDSCH或TB中，参考载波的末尾的调度单元(末尾也可以是通过绑定窗的大小来确定，即事先规定了一个绑定窗内的多个TB的HARQ-ACK复用在一起的，绑定窗结束位置能被告知UE或UE通过约定规则暗含获得)。参考载波的末尾调度单元实际上可以没有调度TB，但是对应的其他载波的调度单元中要有数据。例如图9中，CC#4被配置为参考载波时，此时末尾的调度单元在CC#4中未调度TB，但对应的其他载波的调度单元中有TB被传输。末尾调度单元之后传输的TB的HARQ-ACK，将不与所述多个TB的HARQ-ACK复用在一起，其中，图9是根据本申请可选实施例提供的按照参考载波的末尾调度单元时长对其他载波的调度单元进行分组的示意图。
这样，在末尾调度单元时长内其他载波的调度单元组新传输的TB，或从末尾调度单元开始处已经开始传输的TB，且这些TB属于所述多个TB， 其中的每个调度单元组对应的HARQ-ACK形成与前一实施例相同。在末尾调度单元之后调度单元组或调度单元中新传输的TB不属于所述多个TB。类似的可以参考图10，其中，图10是根据本申请可选实施例提供的按照参考载波的末尾调度单元时长对其他载波的调度单元进行分组的示意图。
相对于前实施例，本实施例有更小的开销，由于减少了其他载波中分组的调度单元数量，从减少了分组的调度单元使用固定码本的开销。这样其他载波中分组的调度单元只发生在末尾的调度单元，使得总的码本大小将显著减小。
在图10中，指定参考载波为CC#5，此时末尾的调度单元为图10中CC#5的倒数第二个调度单元，那么此时CC#1和CC#2会有调度单元组，这两个CC中在末尾的调度单元组内调度的TB，仍然属于所述多个TB的。之后调度的TB将不属于所述多个TB。对于CC#0最后一个调度单元，由于它和末尾调度单元同时开始传输的，所以也属于所述多个TB的。
本可选实施例对于为UE配置的多个载波，这些载波有不同的SCS或不同的调度单元时长，设置公共的DCI监听时机处(相当于上述实施例中的公共的DCI监听时机处)为多个载波来作为本次调度的TB的最后监听承载DAI的DCI的时机处。从而保证承载DAI的DCI的接收可靠性。
对于为UE配置了多个载波，且载波间有不同的SCS时，如果在所述多个载波中调度传输多个TB，且要求这些TB的HARQ-ACK复用在一起反馈。那么采用动态码本时，传输DAI时，基站为了保证UE在末尾的监听DCI的时机处能接收到DAI，基站需要在末尾的监听DCI的时机处发送承载DAI信息的DCI不少于要求的数量。例如约定数量为4次。
如图11，为UE配置多个CC，且SCS最大的CC有5个CC，那么此时UE可以使用动态码本，通过DAI机制来得到最终反馈HARQ-ACK的码本大小，为了防止在末尾的监听DCI的时机处丢失承载DAI的DCI，所以， 基站要求在末尾的监听DCI的时机处至少发送4次承载DAI的DCI；其中，图11是根据本申请实施例提供的在末尾的监听DCI时机处发送要求数量的DAI的示意图。
这种操作要求为UE配置的多个CC中有足够数量(例如大于等于5个)的大的SCS，例如图10中要求CC#1～CC#5是该UE的末尾的监听DCI的实际，且载波数量等5。
为了降低上述的载波中同一SCS的数量限制，下面提供一种优化：
(1)参考图12，图12是根据本申请实施例提供的公共的DCI监听时机处的配置示意图一，在UE配置的多个载波(这些载波具有不同的SCS或不同的调度单元时长)，通过所述多个载波为UE传输了多个PDSCH或TB，且要求这些PDSCH或TB的HARQ-ACK复用在一起(形成一个码本)，本例中为其中部分或全部载波设置公共的监听DCI的时机处，例如图12中示意了为全部CC设置的一个公共的监听DCI的时机处。公共的监听DCI的时机处按照最小SCS的载波(也可以称为参考载波，相当于上述实施例中的第二参考载波)的调度单元(相当于上述实施例中的第二指定调度单元)的DCI位置处进行设置(或者，也可以认为是所述多个载波同时监听DCI的时机，这个时机处每个载波都能传输DCI)。
考虑到DAI对于可靠性要求，尤其是上述复用HARQ-ACK的多个TB的末尾的DCI接收可靠性(因为只要接收到末尾处的DCI中的DAI，DAI机制就可以保证工作了)更加重要。所以，对于上述多个CC中调度的多个TB(这些TB的HARQ-ACK被要求复用在一起)设置它们本次调度的末尾结束在一个公共的监听DCI的时机处。在该时机处，UE能够监听所有的CC的DCI，这样承载DAI的DCI只要在该时机处被发送，且只要发送DAI的载波数量大于等于5(该数字可以根据要求进行修改的，其他位置处的数字也是类似的，可以根据要求进行修改的)时，UE就能够至少接收到一次 DAI(根据前面的4次DCI接收中至少正确接收一次DCI的假设)。这样就只要求配置给UE总的载波数量大于等于5个即可，从而不再要求相同SCS的载波数量满足要求，而是总的载波数只要满足要求即可。
这种方式能被总结为，在为UE配置的载波中，载波具有不同的SCS，设置公共的DCI监听时机处，至少在本次调度的多个TB的末尾设置公共的DCI监听时机处来可靠获取DAI信息(DCI承载着DAI)，在每个载波中，在末尾公共的DCI监听时机处之后的调度单元中调度TB的HARQ-ACK不和前面所述多个TB的HARQ-ACK复用在一起。
(2)参考图13，图13是根据本申请实施例提供的公共的DCI监听时机处的配置示意图二，有的情况下，为UE配置的载波数量是很多，例如十几个载波，如果有不同的SCS或不同的调度单元时长，那么随着不同SCS的载波数量增加为所有载波设置公共的DCI监听时机处将变得困难。在这种情况下，由于不同SCS的载波数量比较多，可以选择部分载波来设置公共的监听DCI的时机处来作为本次调度的所述多个TB的末尾的DCI监听时机，这些DCI并承载着DAI。例如图12中，为UE配置了6个载波，设置公共的DCI监听时机处如图所示意的。公共的监听DCI的时机处是部分载波的，且不是按照最小SCS的载波的调度单元的DCI位置处进行设置，此时可以认为公共的监听DCI的时机是按照参考载波(此时的参考载波为CC#3或CC#4或CC#5)的调度单元进行设置的，参数载波可以是基站配置给UE的。
(3)在设置公共的监听DCI的时机处时，如何选择那些载波作为公共的监听DCI的时机的载波呢？下面提供一种方式。
定义个载波数量门限，假设为N，假设被配置给UE的多个载波中使用的SCS有3种，分别是15KHz、30KHz和60KHz。
一种方式是所述多个载波中，60KHz载波的数量大于等于N，采用本 例中图11的方式，设置公共的监听DCI的时机处仅在60KHz的载波之间。这是因为60KHz的载波数量满足N。
另一种方式是所述多个载波中，60KHz载波的数量小于等于N，同时60KHz载波的数量和30KHz载波数量之和大于等于N，采用30KHz为参考载波，使用它的调度单元设置公共的监听DCI的时机处，即在30KHz和60KHz的载波之间设置公共的监听DCI的时机处。
另一种方式是所述多个载波中，60KHz载波的数量和30KHz载波的数量之和小于等于N，同时30KHz载波的数量和15KHz载波数量之和大于等于N，采用15KHz为参考载波，使用它的调度单元设置公共的监听DCI的时机处，即在15Khz，30KHz和60KHz的载波之间设置公共的监听DCI的时机处。
这种方式只是一个例子为了优化部分载波之间设置公共的监听DCI的时机处。
