Description

确定HARQ反馈时延的方法及装置、存储介质 技术领域
本公开涉及通信领域，尤其涉及确定HARQ反馈时延的方法及装置、存储介质。
背景技术
5G(5th generation mobile networks，第5代移动通信技术)NR(New Radio，新空口)协议中，基站通过DCI(Downlink Control Information，下行控制信息)调度下行数据，让下行数据在时间单元n中的PDSCH(Physical Downlink Shared Channel，物理下行共享信道)上传输，并在DCI中指示终端在时间单元(n+k1)中的PUCCH(Physical Uplink Control Channel，物理上行链路控制信道)，反馈针对时间单元n中传输的下行数据的HARQ(Hybrid Automatic Repeat reQuest，混合自动重传请求)结果。
其中，k1的数值就表示HARQ结果的反馈时延，即，终端在时间单元n上接收到PDSCH，在时间单元(n+k1)的PUCCH上发送该PDSCH对应的HARQ结果，这就要求终端在k1个时间单元中能完成对PDSCH的解调和HARQ结果信息的生成。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
在本公开使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
在本公开实施例中，涉及到的DCI为预设格式的DCI，其中，预设格式是基站使用的用于调度PDSCH的默认格式，例如1-0格式。1-0格式的DCI可以用在基站与终端之间建立RRC(Radio Resource Control，无线资源控制)连接之前。由于基站与终端之间还未建立RRC连接，基站无法通过RRC参数将HARQ反馈时延k1的取值告知终端，因此，1-0格式的DCI对应的k1集合的取值一般需要预先在协议中进行定义。在52.6GHz以下的低频段通信系统中，针对1-0格式的DCI，协议中定义的k1集合的取值包括{1，2，3，4，5，6，7，8}。
在低频段通信系统中，可选的SCS(SubCarrierSpacing，子载波带宽)可以为15KHz(千赫兹)、30KHz、60KHz、120KHz，时间单元一般采用slot(时隙)。在15KHz的子载波带宽的情况下，一个slot的时长为1ms(毫秒)，在30KHz子载波带宽的情况下，一个slot的时长为0.5ms，在60KHz子载波带宽的情况下，一个slot的时长为0.25ms，依次类推。可以看出子载波带宽越大，一个slot的时长越短。
而在高频段的通信协议中，本公开实施例中的高频段可以指60GHz(吉赫)左右，为了应对相位噪声，通常会选取较大的SCS，例如960KHz。在SCS为960KHz的情况下，一个slot的时长为0.015625ms，也即1/64ms。
可以看出，在高频段通信系统中，SCS采用960KHz的情况下，一个slot的时长远远低于1ms。在DCI采用1-0格式的情况下，目前标准中规定的k1是从{1，2，3，4，5，6，7，8}集合中选择的一个数值。即k1的最大值为8，也即0.125ms。在一个slot时长远低于1ms的情况下，终端 很难完成PDSCH解调和HARQ结果的生成。
本公开就是针对高频段通信系统中，一个slot的时长远小于1ms的情况，所提供的确定HARQ反馈时延的方案。
下面先从基站侧，介绍一下本公开提供的确定HARQ反馈时延的方法。
本公开实施例提供了一种确定HARQ反馈时延的方法，该方法用于基站，参照图1所示，图1是根据一实施例示出的一种确定HARQ反馈时延的方法流程图，该方法可以包括以下步骤：
在步骤101中，在协议中预先定义的、与预设格式的下行控制信息DCI对应的多个HARQ反馈时延集合中，确定目标HARQ反馈时延集合。
在本公开实施例中，预设格式是指1-0格式，可以在协议中预先定义对应了1-0格式的DCI的多个HARQ反馈时延集合，多个HARQ反馈时延集合对应不同的子载波带宽。例如，240KHz的SCS对应HARQ反馈时延集合1，480KHz的SCS对应HARQ反馈时延集合2，960KHz的SCS对应HARQ反馈时延集合3……。
基站可以从上述多个HARQ反馈时延集合中，选取一个作为目标HARQ反馈时延集合。
在步骤102中，发送用于指示目标时延值的所述预设格式的DCI给终端。
在本公开实施例中，目标HARQ反馈时延集合中包括了多个时延值，基站可以根据当前终端的业务需求，为终端选择一个作为目标时延值。进一步地，基站可以将用于指示该目标时延值的预设格式的DCI，发送给终端。后续由终端侧根据预设格式的DCI，确定目标时延值。
上述实施例中，基站可以从协议中预先定义的、与预设格式的DCI对应的多个HARQ反馈时延集合中，选择一个作为目标HARQ反馈时延集合。其中，多个HARQ反馈时延集合对应不同的子载波带宽。进一步地，基站发送用于指示目标时延值的所述预设格式的DCI给终端，让终端可以确定目标时延值。其中，目标时延值是所述目标HARQ反馈时延集合所包 括的多个时延值中的一个。本公开实现了在高频段通信系统中，针对一个时间单元远小于1ms的情况，确定HARQ反馈时延的目的。
在一可选实施例中，协议中预先定义的多个HARQ反馈时延集合对应不同的子载波带宽。
其中，由于SCS越大，一个slot的时长就越小，为了确保终端可以在时延值对应的时间单元内完成对PDSCH的解调和生成HARQ反馈结果，在多个HARQ反馈时延集合中，子载波带宽越大，对应的HARQ反馈时延集合中的最大时延值可以越大。
例如，子载波带宽为240KHz，对应的HARQ反馈时延集合1，最大时延值为m1，子载波带宽为480KHz，对应的HARQ反馈时延集合2，最大时延值为m2，子载波带宽为960KHz，对应的HARQ反馈时延集合3，最大时延值为m3，……。其中，m1<m2<m3<……。
具体地，HARQ反馈时延集合的取值可以例如以下所示：
例如，120KHz及以下的SCS的情况下，HARQ反馈时延集合的取值包括{1，2，3，4，5，6，7，8}，240KHz及以上SCS的情况下，HARQ反馈时延集合的取值包括{4，6，8，10，12，14，16}。
再例如，240KHz及以下的SCS的情况下，HARQ反馈时延集合的取值包括{1，2，3，4，5，6，7，8}，在480KHz及以下的SCS的情况下，HARQ反馈时延集合的取值包括{5，6，7，8，9，10，11，12}，960KHz及以下的SCS的情况下，HARQ反馈时延集合的取值包括{4，8，12，16，20，24，28，32}。
以上仅为举例说明，标准中实际定义的HARQ反馈时延集合并不限于以上取值的组合。
基站可以根据当前采用的子载波带宽，确定与当前采用的子载波带宽对应的HARQ反馈时延集合作为目标HARQ反馈时延集合。例如，当前采用的子载波带宽为480KHz，则可以将对应的HARQ反馈时延集合2作为目标HARQ反馈时延集合。
上述实施例中，可以将与当前采用的子载波带宽对应的HARQ反馈时延集合作为目标HARQ反馈时延集合。可选地，协议中预先定义的多个HARQ反馈时延集合中，子载波带宽越大，对应的HARQ反馈时延集合中的最大时延值越大。本公开可以在高频段通信系统中，确保终端可以在目标时延值对应的时间单元内，完成对PDSCH的解调和生成HARQ反馈结果，实现了在高频段通信系统中，确定HARQ反馈时延的目的。
在一实施例中，参照图2所示，图2是根据图1所示的实施例示出的另一种确定HARQ反馈时延的方法流程图，在步骤102之后，该方法还可以包括：
在步骤103中，根据协议中预先定义的所述目标HARQ反馈时延集合所包括的时延值的总数目，确定所述预设格式的DCI中指定信息域占用的比特位数目。
其中，所述指定信息域是所述DCI中用于指示所述目标时延值的信息域。可以根据协议中预先定义的所述目标HARQ反馈时延集合所包括的时延值的总数目，来确定该指定信息域占用的比特位数目。
在本公开实施例中，假设目标HARQ反馈时延集合所包括的时延值的总数目为N，则指定信息域占用的比特位数目为
Figure PCTCN2020100720-appb-000001
其中，
Figure PCTCN2020100720-appb-000002
表示向上取整的计算。N的取值可以为8、16等等，在协议中预先约定，本公开对此不作限定。例如，N的取值为8时，指定信息域占用的比特位数目为3。
在步骤104中，确定所述目标时延值在所述目标HARQ反馈时延集合中的顺序值。
在本公开实施例中，可以先确定目标时延值在所述目标HARQ反馈时延集合中的顺序值。其中，顺序值可以从0开始，依次递增。例如，目标HARQ反馈时延集合的取值包括{5，6，7，8，9，10，11，12}，目标时延值为8，则对应的顺序值为3。
在步骤105中，将占用所述比特位数目的所述指定信息域的比特值设置为与所述顺序值相等。
例如，指定信息域占用3个比特位。目标时延值为8，对应的顺序值为3，通过占用3个比特位的指定信息域的比特值来表示，该比特值可以为011。
相应地，步骤103可以包括：发送预设格式的DCI到终端，其中，DCI中指定信息域占用3个比特位，且比特值为011。
上述实施例中，可以根据协议中预先定义的目标HARQ反馈时延集合所包括的时延值的总数目，来确定预设格式的DCI中指定信息域所占用的比特位数目。其中，所述指定信息域是所述DCI中用于指示所述目标时延值的信息域。另外，还可以根据目标时延值，确定占用所述比特位数目的所述指定信息域的比特值。从而实现了在高频段通信系统中，通过预设格式的DCI的指定信息域将目标时延值发送给终端的目的。
下面再从终端侧，介绍一下本公开提供的确定HARQ反馈时延的方法。
本公开实施例提供了另一种确定HARQ反馈时延的方法，该方法用于终端，参照图3所示，图3是根据一实施例示出的另一种确定HARQ反馈时延的方法流程图，该方法可以包括以下步骤：
在步骤201中，接收基站发送的预设格式的下行控制信息DCI。
在本公开实施例中，预设格式是基站使用的用于调度PDSCH的默认格式，例如1-0格式。
在步骤202中，根据所述预设格式的DCI，确定进行HARQ反馈的目标时延值。
在本公开实施例中，在预设格式的DCI中包括用于指示目标时延值的指定信息域，终端侧可以根据指定信息域来确定目标时延值。
上述实施例中，终端可以接收基站发送的预设格式的下行控制信息DCI，从而根据该预设格式的DCI，确定进行HARQ反馈的目标时延值。实现了在高频段通信系统中，确定HARQ反馈时延的目的。
在一可选实施例中，参照图4所示，图4是根据图3所示的实施例示出的另一种确定HARQ反馈时延的方法流程图，步骤202可以包括：
在步骤202-1中，在协议中预先定义的、与预设格式的下行控制信息DCI对应的多个HARQ反馈时延集合中，确定目标HARQ反馈时延集合。
在本公开实施例中，协议中预先定义的多个HARQ反馈时延集合可以对应不同的子载波带宽。可以将与当前采用的子载波带宽对应的HARQ反馈时延集合作为所述目标HARQ反馈时延集合。同样地，多个HARQ反馈时延集合中，所述子载波带宽越大，对应的HARQ反馈时延集合中的最大时延值越大，确保终端侧可以在目标时延值对应的时域单元内解调出PDSCH和生成HARQ反馈结果。
在步骤202-2中，根据协议中预先定义的所述目标HARQ反馈时延集合所包括的时延值的总数目，确定所述预设格式的DCI中指定信息域占用的比特位数目。
其中，所述指定信息域是所述DCI中用于指示所述目标时延值的信息域。协议中已经预先定义了目标HARQ反馈时延集合所包括的时延值的总数目，该总数目假设为N，则终端可以确定预设格式的DCI中指定信息域占用的比特位数目为
Figure PCTCN2020100720-appb-000003
在步骤202-3中，确定占用所述比特位数目的所述指定信息域的比特值。
在本公开实施例中，读取占用
Figure PCTCN2020100720-appb-000004
的指定信息域的比特值。例如，N为8，则读取占用3个比特位的指定信息域的比特值。
在步骤202-4中，在所述目标HARQ反馈时延集合中，将顺序值与所述比特值相等的时延值作为所述目标时延值。
在本公开实施例中，目标HARQ反馈时延集合中的顺序值可以从0开始排序，依次递增。在目标HARQ反馈时延集合已知，且目标时延值在目标HARQ反馈时延集合中的顺序值已知的情况下，可以确定出目标时延值。
在一可选实施例中，参照图5所示，图5是根据图3所示的实施例示出的另一种确定HARQ反馈时延的方法流程图，在步骤202之后，上述方法还可以包括：
在步骤203中，确定接收所述预设格式的DCI的时域单元。
在本公开实施例中，可以确定出接收到预设格式的DCI的时域单元。其中，时域单元可以采用但不限于slot等。
在步骤204中，确定接收所述预设格式的DCI的时域单元的序号与所述目标时延值的和值。
在本公开实施例中，假设确定接收所述预设格式的DCI的时域单元的序号为n，目标时延值为k1，则和值为(n+k1)。
在步骤205中，将所述和值所指示的时域单元作为针对所述预设格式的DCI所调度的PDSCH进行HARQ反馈的目标时域单元。
在本公开实施例中，1-0格式的DCI用于调度某个PDSCH，终端可以将上述和值所指示的时域单元作为目标时域单元，在目标时域单元上对DCI调度的PDSCH进行HARQ结果的反馈。例如，反馈是否成功接收PDSCH上的下行数据，成功接收反馈ACK，未成功接收可以反馈NACK。
上述实施例中，终端可以根据确定的目标时延值，进行HARQ结果的反馈，从而实现了在高频段通信系统中，根据确定的目标时延值进行HARQ结果反馈的目的。
在一可选实施例中，参照图6所示，图6是根据一实施例示出的另一种确定HARQ反馈时延的方法流程图，该方法可以包括以下步骤：
在步骤301中，基站在协议中预先定义的、与预设格式的DCI对应的多个HARQ反馈时延集合中，将与当前采用的子载波带宽对应的HARQ反馈时延集合作为目标HARQ反馈时延集合。
在本公开实施例中，多个HARQ反馈时延集合对应不同的子载波带宽，且子载波带宽越大，对应的HARQ反馈时延集合中的最大时延值越大。
在步骤302中，所述基站根据协议中预先定义的所述目标HARQ反馈 时延集合所包括的时延值的总数目，确定所述预设格式的DCI中指定信息域占用的比特位数目。
其中，所述指定信息域是所述DCI中用于指示目标时延值的信息域，目标时延值是目标HARQ反馈集合所包括的多个时延值中的一个。
在步骤303中，所述基站确定目标时延值在所述目标HARQ反馈时延集合中的顺序值。
在步骤304中，所述基站将占用所述比特位数目的所述指定信息域的比特值设置为与所述顺序值相等。

在步骤306中，所述终端在接收到所述预设格式的DCI之后，在所述多个HARQ反馈时延集合中，将与当前采用的子载波带宽对应的HARQ反馈时延集合作为所述目标HARQ反馈时延集合。
在步骤307中，所述终端根据协议中预先定义的所述目标HARQ反馈时延集合所包括的时延值的总数目，确定所述预设格式的DCI中指定信息域占用的比特位数目。
在步骤308中，所述终端确定占用所述比特位数目的所述指定信息域的比特值。
在步骤309中，所述终端在所述目标HARQ反馈时延集合中，将顺序值与所述比特值相等的时延值作为所述目标时延值。
