技术领域
本公开的一些实施例涉及无线通信技术领域，尤其涉及一种HARQ-ACK码本的确定方法和终端。
背景技术
在长期演进(Long Term Evolution，简称LTE)系统中，网络侧在发送一个传输块(TB，transport block)时，每个传输块会分成多个码块(Code block)。终端(User Equipment，简称UE)需要针对整个传输块发送混合自动重传请求(Hybrid Automatic Repeat reQuest，简称HARQ)确认/不确认(ACK/NACK)信息，如果传输块中的某个码块传输错误，需要重传整个传输块内的所有码块。
在第五代(5th Generation，简称5G)新无线(New Ratio，简称NR)移动通信系统的标准化过程中，引入了码块组(Code Block Group，简称CBG)传输模式，即将一个传输块的码块进行分组，1个传输块包含多个码块组，1个码块组包含1个或多个码块。终端可以根据各个码块组的接收情况，反馈各个码块组的ACK/NACK，这样，网络侧只需要重传终端接收错误的码块组，从而减小重传所需要的资源，同时也降低了终端在接收重传数据进行合并时的处理时延。
当终端没有配置码块组传输的模式时，终端反馈的ACK/NACK为每个传输块反馈1个比特。当终端配置了码块组传输的模式时，终端反馈的ACK/NACK的类型包括传输块级别(TB level)ACK/NACK和码块组级别(CBG level)ACK/NACK。此时，TB level ACK/NACK中，对每个传输块， 终端反馈M个比特，其中每个比特的值相同，均用于指示该传输块的ACK/NACK。CBG level ACK/NACK中，对每个传输块，终端反馈M个比特，其中每个比特对应每个码块组的ACK/NACK。具体的，终端根据所接收到的调度下行数据的下行控制信息(Downlink Control Information，简称DCI)的格式确定ACK/NACK反馈的类型。当终端-接收到的DCI格式为回馈(fallback)DCI时，终端反馈的ACK/NACK类型为TB level ACK/NACK。当终端接收到的DCI格式为普通的DCI时，终端反馈的ACK/NACK类型为CBG level ACK/NACK。
为了满足不同需求的业务和不同的应用场景，NR系统的子载波间隔不再是单一的15kHz，可以支持多种子载波间隔，不同的子载波间隔可以适用于不同的场景。在NR Rel-15中，每个载波最大的带宽是400MHz。但是考虑到终端的能力，终端支持的最大带宽可以小于400MHz，且终端可以工作在多个小的带宽部分(bandwidth part，BWP)上。每个带宽部分对应于一个参数集(Numerology)，带宽(bandwidth)和频率位置(frequency location)。每个终端可以配置一个或多个BWP，网络侧需要告诉终端在哪一个BWP上工作，即激活(activate)哪一个BWP。激活BWP可以通过DCI来动态切换。
对频分双工(Frequency Division Dual，简称FDD)场景下，当终端的激活BWP发生了切换，且不同的下行(DL)BWP的码块组传输配置不同时，时间窗内的多个物理下行共享信道(Physical Downlink Shared Channel，简称PDSCH)所关联的BWP的传输块传输配置不同，因此终端可能无法确定HARQ-ACK码本(codebook)的大小。
发明内容
本公开的一些实施例提供一种HARQ-ACK码本的确定方法和终端，以解决终端可能无法确定HARQ-ACK码本的问题。
为了解决上述技术问题，第一方面，本公开的一些实施例提供了一种HARQ-ACK码本的确定方法，包括：
根据HARQ-ACK码本对应的至少一个PDSCH所在的BWP的码块组配置，确定所述HARQ-ACK码本；或者，
根据调度所述HARQ-ACK码本对应的至少一个PDSCH的PDCCH所在的BWP的码块组配置，确定所述HARQ-ACK码本。
第二方面，本公开的一些实施例提供了一种终端，包括：
确定模块，用于根据HARQ-ACK码本对应的至少一个物理下行共享信道PDSCH所在的BWP的码块组配置，确定所述HARQ-ACK码本；或者，根据调度所述HARQ-ACK码本对应的至少一个PDSCH的物理下行控制信道PDCCH所在的BWP的码块组配置，确定所述HARQ-ACK码本。
第三方面，本公开的一些实施例提供了一种终端，包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时所述处理器实现上述HARQ-ACK码本的确定方法的步骤。
第三方面，本公开的一些实施例提供了一种计算机可读存储介质，所述计算机可读存储介质上存储计算机程序，所述计算机程序被处理器执行时所述处理器实现上述HARQ-ACK码本的确定方法的步骤。
在本公开的一些实施例中，对终端如何确定HARQ-ACK码本的方法进行了明确，避免了终端在切换了BWP之后，在确定HARQ-ACK码本时可能存在的模糊问题。
附图说明
图1为本公开的一些实施例的HARQ-ACK码本的确定方法的示意图；
图2为本公开的一些实施例的终端的示意图；以及
图3为本公开的一些实施例的终端的示意图。
具体实施方式
下面将结合本公开的一些实施例中的附图，对本公开的一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
对于周期出现且数据包大小较为固定的业务，为了减少下行控制信令的开销，网络可以采用半静态调度的方式，持续分配一定的资源，用于周期业务的传输。这种在下行半静态调度的方式称为DL半静态调度(Semi-Persistent Scheduling，简称SPS)，DLSPS能够降低调度周期性发送且较小的VoLTE语音包的开销(主要是(物理下行控制信道Physical Downlink Control Channel，简称PDCCH)的开销)，从而使得更多的资源可用于调度额外的终端。
HARQ-ACK码本(codebook)的确定方式有两种，半静态和动态。当HARQ-ACK码本是半静态的确定方式时，HARQ-ACK码本的大小是确定的。这种情况下，HARQ-ACK码本的大小是根据时间窗内所包含的PDSCH接收时刻来确定的。其中，该时间窗大小是根据高层配置的参数来计算得到的。该时间窗内，可能接收到的PDSCH的候选(candidates)数量是确定的。因此HARQ-ACK码本的大小是确定的。
当HARQ-ACK码本是动态确定时，HARQ-ACK码本的大小是可以动态变化的。此时，UE根据高层参数确定时间窗的大小，然后根据该时间窗内所接收到的PDCCH来确定HARQ-ACK码本的大小。由于在时间窗内接收的PDCCH数量是不确定的，因此HARQ-ACK码本的大小是动态变化的。
本公开的一些实施例中的HARQ-ACK码本的确定方法可用于确定半静态HARQ-ACK码本，也可以用于确定动态HARQ-ACK码本。
本公开的一些实施例中所描述的场景中，均是FDD场景。
请参考图1，图1为本公开的一些实施例的HARQ-ACK码本的确定方法，该确定方法应用于终端，包括：
步骤11：根据HARQ-ACK码本对应的至少一个PDSCH所在的带宽部分BWP的码块组配置，确定所述HARQ-ACK码本；或者，根据调度所述HARQ-ACK码本对应的至少一个PDSCH的PDCCH所在的BWP的码块组配置，确定所述HARQ-ACK码本。
本公开的一些实施例中的HARQ-ACK码本的确定方法，可选地，应用于终端切换了激活的BWP的情况下。本公开的一些实施例中发生切换的BWP，可以是同一小区的不同BWP，也可以是不同小区的不同BWP。
本公开的一些实施例中，PDSCH所在的BWP是指PDSCH接收时刻的 BWP，PDCCH所在的BWP是指用于检测到PDCCH的BWP。
也就是说，本公开的一些实施例中，可以采用两种方法确定所述HARQ-ACK码本。
方法一是：根据所述HARQ-ACK码本对应的至少一个物理下行共享信道PDSCH所在的带宽部分BWP的码块组配置，确定所述HARQ-ACK码本。
方法二是：根据调度所述HARQ-ACK码本对应的至少一个PDSCH的物理下行控制信道PDCCH所在的BWP的码块组配置，确定所述HARQ-ACK码本。
本公开的一些实施例中，BWP的码块组配置包括BWP是否配置了码块组传输模式，如果配置了码块组传输模式，则针对每一传输块，终端反馈M个比特的ACK/NACK，M是传输块中配置的码块组的数量。如果没有配置码块组传输模式，则针对每一传输块，终端反馈1比特的ACK/NACK。
在本公开的一些实施例中，对当终端配置了HARQ-ACK码本时，如何确定HARQ-ACK码本的方法进行了明确，避免了终端在切换了BWP之后，在确定HARQ-ACK码本时可能存在的模糊问题。
上述内容中提到，HARQ-ACK码本的大小是根据时间窗内所包含的PDSCH接收时刻来确定的。其中，该时间窗大小是根据高层配置或预定义的参数来计算得到的。该时间窗内，可能接收到的PDSCH的候选数量是确定的。本公开的一些实施例中，时间窗内所包含的PDSCH接收时刻可以是一个，也可以是多个。当时间窗内所包含的PDSCH接收时刻是一个时，即HARQ-ACK码本对应的PDSCH的个数为一个，当时间窗内所包含的PDSCH接收时刻是多个时，即HARQ-ACK码本对应的PDSCH的个数为多个。当时间窗内所包含的PDSCH接收时刻是多个时，并不是每一个PDSCH接收时刻上，都有PDSCH传输，一些PDSCH接收时刻上，也可能没有PDSCH传输，即使在某些PDSCH接收时刻上没有PDSCH传输，终端也始终为该些PDSCH传输预留HARQ-ACK比特。本公开的一些实施例中，PDSCH接收时刻的集合根据时间窗内PDCCH的检测周期和检测时刻确定。
因而，上述内容中的，根据所述HARQ-ACK码本对应的至少一个PDSCH所在的BWP的码块组配置，确定所述HARQ-ACK码本，或者，根据调度所述HARQ-ACK码本对应的至少一个PDSCH的PDCCH所在的BWP的码块 组配置，确定所述HARQ-ACK码本，其中，当HARQ-ACK码本对应的PDSCH的个数为一个时，该“至少一个”是指一个，当HARQ-ACK码本对应的PDSCH的个数为多个时，该“至少一个”是指一个或多个。
下面分别对根据方法一和方法二确定HARQ-ACK码本的具体方法进行说明。
针对方法一，即“根据所述HARQ-ACK码本对应的至少一个PDSCH所在的BWP的码块组配置，确定所述HARQ-ACK码本”可以包括：
方式1：根据所述HARQ-ACK码本对应的每一个PDSCH所在的BWP的码块组配置，确定所述HARQ-ACK码本；或者
方式2：根据所述HARQ-ACK码本对应的每一PDSCH所在的BWP组成的BWP集合中，配置的码块组数量最大的BWP的码块组配置，确定所述HARQ-ACK码本；或者
方式3：根据所述HARQ-ACK码本对应的最后一个PDSCH所在的BWP的码块组配置，确定所述HARQ-ACK码本。
下面对方法一中的上述三种方式的具体确定方法举例进行说明。
方式1A
所述根据所述HARQ-ACK码本对应的每一个PDSCH所在的BWP的码块组配置，确定所述HARQ-ACK码本，包括：根据所述HARQ-ACK码本对应的每一个PDSCH所在的BWP的码块组配置中的码块组数量，确定所述HARQ-ACK码本对应的每一个PDSCH的HARQ-ACK比特，根据所述HARQ-ACK码本对应的每一个PDSCH的HARQ-ACK比特，确定所述HARQ-ACK码本。
如，假设接收候选的PDSCHm对应的BWP配置的码块组的数量为CBG_num(m)，HARQ-ACK码本的大小为：sum(CBG_num(m)×N TB),m＝0～M-1，M为HARQ-ACK码本对应的所有PDSCH的数量，N TB为传输块的数量，m是候选PDSCH的编号。
方式2A
所述根据所述HARQ-ACK码本对应的每一PDSCH所在的BWP组成的BWP集合中，配置的码块组的数量最大的BWP，确定所述HARQ-ACK码本， 包括：从所述HARQ-ACK码本对应的每一PDSCH所在的BWP组成的BWP集合中，选择配置的码块组数量最大的BWP，根据选择的BWP的码块组配置中的码块组的数量，确定所述HARQ-ACK码本对应的每一个PDSCH的HARQ-ACK比特，根据所述HARQ-ACK码本对应的每一个PDSCH的HARQ-ACK比特，确定所述HARQ-ACK码本；

本公开的一些实施例中，码块组配置相同的BWP是指至少配置的码块组的数量相同的BWP。
也就是说，对在不同的BWP上接收的一个或多个PDSCH，终端不反馈HARQ-ACK，即HARQ-ACK码本不包含该一个或多个PDSCH的ACK/NACK。
进一步的，对在不同的BWP上接收的一个或多个PDSCH，且不同的BWP的码块组配置不同，终端不反馈HARQ-ACK，即HARQ-ACK码本不包含该一个或多个PDSCH的ACK/NACK。

所述方法还包括：若所述终端接收指示切换激活BWP的指令，在反馈所述HARQ-ACK码本对应的PDSCH对应的HARQ-ACK比特之前，忽略所述指令。
也就是说，在反馈所述HARQ-ACK码本对应的PDSCH的HARQ-ACK比特之前，终端不允许执行BWP的切换。可以在反馈所述HARQ-ACK码本对应的PDSCH的HARQ-ACK比特之后，再执行BWP的切换。
在本公开的一些可选实施例中，若所述终端接收指示切换激活BWP的指令，且切换前后的BWP的码块组配置不同时，在反馈所述HARQ-ACK码本对应的PDSCH对应的HARQ-ACK比特之前，忽略所述指令。

进一步的，触控面板1071可覆盖在显示面板1061上，当触控面板1071检测到在其上或附近的触摸操作后，传送给处理器110以确定触摸事件的类型，随后处理器110根据触摸事件的类型在显示面板1061上提供相应的视觉输出。虽然在图3中，触控面板1071与显示面板1061是作为两个独立的部件来实现终端的输入和输出功能，但是在某些实施例中，可以将触控面板1071与显示面板1061集成而实现终端的输入和输出功能，具体此处不做限定。
接口单元108为外部装置与终端100连接的接口。例如，外部装置可以包括有线或无线头戴式耳机端口、外部电源(或电池充电器)端口、有线或无线数据端口、存储卡端口、用于连接具有识别模块的装置的端口、音频输入/输出(I/O)端口、视频I/O端口、耳机端口等等。接口单元108可以用于接收来自外部装置的输入(例如，数据信息、电力等等)并且将接收到的输入传输到终端100内的一个或多个元件或者可以用于在终端100和外部装置之间传输数据。
存储器109可用于存储软件程序以及各种数据。存储器109可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等；存储数据区可存储根据手机的使用所创建的数据(比如音频数据、电话本等)等。此外，存储器109可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
处理器110是终端的控制中心，利用各种接口和线路连接整个终端的各个部分，通过运行或执行存储在存储器109内的软件程序和/或模块，以及调用存储在存储器109内的数据，执行终端的各种功能和处理数据，从而对终端进行整体监控。处理器110可包括一个或多个处理单元；可选的，处理器110可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器110中。
终端100还可以包括给各个部件供电的电源111(比如电池)，可选的，电源111可以通过电源管理系统与处理器110逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
另外，终端100包括一些未示出的功能模块，在此不再赘述。
