具体实施方式
发明人在发明过程中注意到:
当终端被配置使用半静态HARQ-ACK码本时,用户设备(User Equipment,UE)首先根据HARQ-ACK反馈时序(K1)、半静态的时隙结构(如果配置了)和物理下行链路共享信道(Physical Downlink Shared Channel,PDSCH)候选时域资源分配信息确定每个载波c上对应在同一个时隙n进行HARQ-ACK反馈的PDSCH位置集合MA,C。然后根据MA,C,将在PDSCH位置集合中接收到的PDSCH的HARQ-ACK映射到HARQ-ACK反馈序列中的对应位置,从而得到时隙n中传输的HARQ-ACK码本。
具体的,UE首先基于高层信令配置的HARQ反馈时序确定载波上在一个时隙中需要进行反馈的时隙个数,然后在这些时隙中,确定每个时隙中可以传输的最大PDSCH个数。如果配置了半静态的时隙结构,需要基于该时隙结构将不满足PDSCH传输条件的候选PDSCH去掉。当存在载波聚合时,每个载波上的HARQ-ACK码本需要分别按照上述过程进行确定,最后将不同载波的HARQ-ACK码本按照载波顺序进行级联得到最终的HARQ-ACK码本。
在NR R15系统中,当一个承载HARQ-ACK的物理上行控制信道(Physical Uplink Control Channel,PUCCH)和承载CSI/SR(CSI:信道状态信息,channel state information;SR:调度请求,Scheduling Request)的PUCCH重叠时,需要将上行控制信息(Uplink Control Information,UCI)进行复用传输。5G NR系统中不支持PUCCH和物理上行链路共享信道(Physical Uplink Shared Channel,PUSCH)的同时传输,因此当PUCCH和PUSCH在时间上重叠时,需要将PUCCH承载的上行控制信息转移到PUSCH上和数据进行复用传输。
在相关技术中,一个时隙中仅能传输一个承载HARQ-ACK的PUCCH,因此只存在一个承载HARQ-ACK的PUCCH和承载其它UCI的PUCCH或者PUSCH重叠的情况。然而,将来可能会出现支持一个时隙中使用多个时分的PUCCH承载HARQ-ACK的方案,例如在Rel-16阶段,那么当这些PUCCH和承载其它UCI的PUCCH或PUSCH重叠时,如何将这些PUCCH上承载的HARQ-ACK码本复用在PUCCH或者PUSCH上进行传输,目前还没有具体的方案。一种可能的办法是,多个反馈码本级联,其中每个码本都按照相关技术中的方式独立的去产生半静态码本,但是这样会导致较大的反馈冗余比特。
图1为HARQ-ACK反馈示意图,如图1所示,假设配置的K1集合为{2,3,4,5},上行配置了两个子时隙进行HARQ-ACK反馈,假设在确定半静态码本时下行PDSCH也基于上行子时隙来进行子时隙的划分,即下行子时隙的边界和上行子时隙的边界对齐,那么时隙n+3中两个子时隙中的PUCCH对应的反馈窗口存在较大的重叠区域,例如时隙n+3中第一个子时隙中的PUCCH对应的反馈窗口包括时隙n中的第二个子时隙,时隙n+1和时隙n+2中的第一个子时隙,时隙n+3中第二个子时隙中的PUCCH对应的反馈窗口包括时隙n+1和时隙n+2,因此两个反馈窗口的重叠区域为时隙n+1和时隙n+2中的第一个子时隙,在重叠区域中的PDSCH传输位置中基站仅会指示对应的HARQ-ACK反馈在其中一个PUCCH资源进行反馈,但是这些重叠区域的PDSCH传输位置在两个PUCCH承载的HARQ-ACK反馈码本中都占有对应的HARQ-ACK反馈比特位置,若是这两个HARQ-ACK码本需要进行复用传输,如果每个码本都按照相关技术中的方式独立的去产生半静态码本,则重叠区域的PDSCH传输位置对应的反馈比特存在两份,多余的一份属于冗余信息。
综上,在5G NR中,由于Rel-15阶段一个时隙中仅能传输一个承载HARQ-ACK的PUCCH,因此只存在一个承载HARQ-ACK的PUCCH和承载其它UCI的PUCCH重叠或者和PUSCH重叠的情况。而以Rel-16阶段为例,将会出现支持一个时隙中使用多个时分的PUCCH承载HARQ-ACK的方案,当这些PUCCH和另一个承载其它UCI的PUCCH重叠或者和一个PUSCH 重叠时,如果将这些PUCCH上承载的HARQ-ACK在PUCCH或者PUSCH上进行复用传输,目前还没有对应的复用传输方案,因此,本公开实施例中将给出一种多个HARQ-ACK复用传输时,半静态码本的确定方案,用以避免产生冗余的反馈比特信息,保证多个HARQ-ACK码本复用传输的性能。
下面结合附图对本公开的具体实施方式进行说明。

具体的,当存在多个HARQ-ACK码本复用传输且多个码本均为半静态码本时,如果多个HARQ-ACK码本中对应的PDSCH传输位置中存在重叠的部分,则对重叠部分仅产生一次HARQ-ACK反馈信息。
实施中,如果多个HARQ-ACK码本中对应的PDSCH传输位置中存在重叠的部分,则在所述HARQ-ACK码本中对重叠部分仅产生一次反馈比特,至少可以包括以下两种方式,下面分别进行说明。
方式一:

基于合并的时隙或子时隙集合,确定集合中每个时隙或子时隙中可以传输的最大PDSCH个数;
在配置了半静态的时隙结构下,基于该时隙结构将不满足PDSCH传输条件的候选PDSCH去掉,得到多个HARQ-ACK码本对应的PDSCH位置集合。
具体的,首先基于配置的HARQ反馈时序确定载波上每一个HARQ-ACK码本对应的时隙/子时隙集合,然后将多个HARQ-ACK码本对应的时隙/子时隙集合合并,去掉其中重复的时隙/子时隙,得到合并的时隙/子时隙集合;
然后基于合并的时隙/子时隙集合,确定每个时隙/子时隙中可以传输的最大PDSCH个数。如果配置了半静态的时隙结构,需要基于该时隙结构将不满足PDSCH传输条件的候选PDSCH去掉,得到多个HARQ-ACK码本对应的PDSCH位置集合。

相应的,本公开实施例中也给出了接收HARQ-ACK反馈的方案,下面进行说明。
图3为网络侧接收HARQ-ACK反馈的方法实施流程示意图,如图所示,可以包括:
步骤301、当存在多个HARQ-ACK码本复用传输且HARQ-ACK码本均为半静态码本时,确定多个HARQ-ACK码本中对应的PDSCH传输位置中存在重叠的部分;

基于配置给终端的HARQ反馈时序确定载波上每一个HARQ-ACK码本对应的时隙或子时隙集合后,将多个HARQ-ACK码本对应的时隙或子时隙集合合并,去掉其中重复的时隙或子时隙,得到合并的时隙或子时隙集合;
基于合并的时隙或子时隙集合,确定集合中每个时隙或子时隙中可以传输的最大PDSCH个数;
在配置了半静态的时隙结构下,基于该时隙结构将不满足PDSCH传输条件的候选PDSCH去掉,得到多个HARQ-ACK码本对应的PDSCH位置集合。
方式二:
基于配置给终端的HARQ-ACK反馈时序K1和所述多个HARQ-ACK码 本所在的时隙或子时隙确定每一个HARQ-ACK码本对应的PDSCH位置集合后,将所述多个HARQ-ACK码本对应的PDSCH位置集合进行合并,去掉其中重复的PDSCH位置,得到所述多个HARQ-ACK码本对应的PDSCH位置集合,根据所述多个HARQ-ACK码本对应的PDSCH位置集合确定接收的HARQ-ACK反馈信息的比特数。
下面以实例对上述两种方式的具体实施进行说明。
采用方式1的实施方式:
图4为实施例中方式1下HARQ-ACK反馈示意图,如图所示,假设终端被配置了一个载波用于传输超高可靠性与超低时延(Ultra Reliable&Low Latency Communication,URLLC)业务,使用15kHz的子载波间隔进行传输,在一个时隙中被配置了两个子时隙用于HARQ-ACK反馈,高层信令配置HARQ反馈使用半静态码本,HARQ时序集合K1包含{2,3,4,5}。
如图4所示,在时隙3中两个子时隙中的HARQ-ACK对应的PUCCH资源都和一个SR资源重叠,假设这两个HARQ-ACK和SR需要复用在一个PUCCH资源上进行传输,终端基于如下方式确定复用传输的HARQ-ACK反馈码本:
终端基于K1集合{2,3,4,5}确定时隙3中第一个子时隙对应的下行传输子时隙为时隙0中的第二个子时隙,时隙1中的两个子时隙和时隙2中的第一个子时隙。时隙3中第二个子时隙对应的下行传输子时隙为时隙1和时隙2中的四个子时隙。
因此,时隙3中两个子时隙对应的下行传输子时隙集合为子时隙{1,2,3,4,2,3,4,5},然后去掉其中重复的子时隙,得到合并的子时隙集合{1,2,3,4,5},基于合并的时隙/子时隙集合,终端可以确定每个子时隙中可以传输的最大PDSCH个数。
假设时隙0/1/2均为下行时隙,且每个子时隙中最大传输1个PDSCH,可以得到PDSCH传输位置集合中包含5个PDSCH传输位置,如果基站在子时隙3和子时隙4中调度的PDSCH传输,当终端正确接收到这些PDSCH传输时,终端复用传输的HARQ-ACK反馈码本00110。
采用方式2的实施方式:
图5为实施例中方式2下HARQ-ACK反馈示意图,如图5所示,在时隙3中两个子时隙中的HARQ-ACK对应的PUCCH资源都和一个PUSCH重叠,假设这两个HARQ-ACK需要复用在PUSCH资源上进行传输,且使用联合编码的方式,终端基于如下方式确定复用传输的HARQ-ACK反馈码本:
终端基于K1集合{2,3,4,5}确定时隙3中第一个子时隙对应的下行传输子时隙为时隙0中的第二个子时隙,时隙1中的两个子时隙和时隙2中的第一个子时隙,因此对应的PDSCH传输位置集合为PDSCH传输位置{1,2,3,4,5,6,7}。
时隙3中第二个子时隙对应的下行传输子时隙为时隙1和时隙2中的四个子时隙,因此对应的PDSCH传输位置集合为PDSCH传输位置{3,4,5,6,7,8}。
因此,将时隙3中两个子时隙对应的PDSCH传输位置集合合并得到PDSCH传输位置{1,2,3,4,5,6,7,3,4,5,6,7,8},然后去掉其中重复的PDSCH传输位置,得到合并的PDSCH传输位置集合{1,2,3,4,5,6,7,8}。合并的PDSCH传输位置集合中包含8个PDSCH传输位置,如果基站在PDSCH传输位置3/4/6/7/8中调度了PDSCH传输,当终端正确接收到这些PDSCH传输时,终端复用传输的HARQ-ACK反馈码本00110111。
基于同一发明构思,本公开实施例中还提供了一种用户设备、基站、HARQ-ACK反馈装置、接收HARQ-ACK反馈的装置、计算机设备存储介质,由于这些设备解决问题的原理与方法相似,因此这些设备的实施可以参见HARQ-ACK反馈方法、接收HARQ-ACK反馈的方法的实施,重复之处不再赘述。

本公开实施例中提供了一种HARQ-ACK反馈装置,包括:
确定模块,用于当存在多个HARQ-ACK码本复用传输且HARQ-ACK码本均为半静态码本时,确定多个HARQ-ACK码本中对应的PDSCH传输位置中存在重叠的部分;
生成模块,用于在所述HARQ-ACK码本中对重叠部分仅产生一次反馈比特。
具体实施可以参见HARQ-ACK反馈方法的实施。
本公开实施例中提供了一种接收HARQ-ACK反馈的装置,包括:
确定模块,用于当存在多个HARQ-ACK码本复用传输且HARQ-ACK码本均为半静态码本时,确定多个HARQ-ACK码本中对应的PDSCH传输位置中存在重叠的部分;
接收模块,用于接收HARQ-ACK反馈信息,所述HARQ-ACK反馈信息是UE对重叠部分仅产生一次反馈比特的HARQ-ACK反馈信息。
具体实施可以参见接收HARQ-ACK反馈的方法的实施。
为了描述的方便,以上所述装置的各部分以功能分为各种模块或单元分别描述。当然,在实施本公开时可以把各模块或单元的功能在同一个或多个软件或硬件中实现。
本公开实施例中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存储有执行上述HARQ-ACK反馈方法和/或接收HARQ-ACK反馈的方法的计算机程序。
具体实施可以参见HARQ-ACK反馈方法和/或接收HARQ-ACK反馈的方法的实施。
综上所述,本公开实施例提供的技术方案中,当存在多个HARQ-ACK码本复用传输时,如果多个HARQ-ACK码本都使用半静态码本,则对多个HARQ-ACK码本中对应的PDSCH传输位置中重叠的部分仅产生一次HARQ-ACK反馈信息。
综上,在相关技术中,只存在一个承载HARQ-ACK的PUCCH和承载其它UCI的PUCCH或者PUSCH重叠的情况。然而,在Rel-16阶段将会支持一个时隙中使用多个时分的PUCCH承载HARQ-ACK,当这些PUCCH和一个PUCCH或PUSCH重叠时,可能会支持这些PUCCH上承载的HARQ-ACK都进行复用传输,目前还没有对应的复用传输方案。本公开实施例提供的技术方案中,给出了一种多个HARQ-ACK复用传输时,半静态码本的确定方案,能够避免产生冗余的反馈比特信息,以保证PUSCH上传输多个HARQ-ACK码本的性能。
本领域内的技术人员应明白,本公开的实施例可提供为方法、系统、或计算机程序产品。因此,本公开可采用完全硬件实施例、完全软件实施例、或结合软件和硬件方面的实施例的形式。而且,本公开可采用在一个或多个其中包含有计算机可用程序代码的计算机可用存储介质(包括但不限于磁盘存储器和光学存储器等)上实施的计算机程序产品的形式。
本公开是参照根据本公开实施例的方法、设备(系统)、和计算机程序产品的流程图和/或方框图来描述的。应理解可由计算机程序指令实现流程图和/或方框图中的每一流程和/或方框、以及流程图和/或方框图中的流程 和/或方框的结合。可提供这些计算机程序指令到通用计算机、专用计算机、嵌入式处理机或其他可编程数据处理设备的处理器以产生一个机器,使得通过计算机或其他可编程数据处理设备的处理器执行的指令产生用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的装置。
这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中,使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品,该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上,使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理,从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
显然,本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样,倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内,则本公开也意图包含这些改动和变型在内。
