Description

用于无线通信的电子设备和方法、计算机可读存储介质
本申请要求于2019年8月16日提交中国专利局、申请号为201910758553.6、发明名称为“用于无线通信的电子设备和方法、计算机可读存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，具体地涉及无线通信系统中的混合自动重传技术。更具体地，涉及一种用于无线通信的电子设备和方法以及计算机可读存储介质。
背景技术
第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)已经提出卫星通信是诸如飞机通信、海上船舶和偏远地区等场景中回程通信最好的(甚至是唯一的)选择，并建议充分利用卫星的能力。在大多数情况下，称为非地面网络(Non-Terrestrial Network，NTN)的卫星通信网络已被预测为第六代移动通信系统的重要部分，其将与未来的地面网络形成集成的无缝网络。因此，卫星通信和网络技术在学术界和工业界都引起了很多兴趣。
混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)技术是一种结合前向纠错(Forward Error Correction，FEC)与自动重传(Automatic Repeat Request，ARQ)的技术。接收端使用循环冗余校验(CRC)来检测接收到的数据包是否出错。如果无错，则接收端会发送一个肯定的确认(ACK)给发送端，发送端收到ACK后，会接着发送下一个数据包。如果出错，则接收端会将该数据包保存在HARQ缓存(buffer)中，并发送一个否定的确认(NACK)给发送端，发送端收到NACK后，会重发相同的数据，而接收端会将保存在HARQ缓存中的数据与后续接收到的数据进行合并，然后对合并后的数据再进行CRC，如果仍然失败，则重复“请求重传，再进行软合并”的过程。HARQ使用停等协议(stop-and-wait process)来发送数据，即，发送端发送一个传 输块(Transmission Block，TB)后，会等待确认信息，在接收到反馈后才会进行下一步动作。此外，为了提高系统效率，引入了HARQ进程(HARQ process)的概念，即，当一个HARQ process在等待确认信息时，发送端可以使用另一个HARQ process继续发送数据，目前5G NR中最大支持16个HARQ process。
例如，在NTN中，由于基站与地面用户之间的往返时延(Round-Trip Delay，RTD)增大，如果继续使用HARQ会导致系统效率降低，因此在地面网络中运行良好的HARQ技术在NTN中不再普遍适用。

具体实施方式
在下文中将结合附图对本发明的示范性实施例进行描述。为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与根据本发明的方案密切相关的设备结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
<第一实施例>
如前所述，例如在诸如NTN的具有较大RTD的场景中，现有的HARQ反馈机制会导致系统效率降低。因此，本申请意在提供一种对HARQ反馈机制进行灵活控制的方案，以使得在保证系统可靠性的情况下，提高系统效率。应该理解，虽然上文中将NTN作为场景的示例，但是本申请的技术方案的应用场景并不限于此，而是可以适当地应用于任何需要灵活的HARQ反馈机制的场合。
图1示出了根据本申请的一个实施例的用于无线通信的电子设备100的功能模块框图，如图1所示，电子设备100包括：获取单元101，被配置为从基站获取下行控制信息(Downlink Control Information，DCI)；以及确定单元102，被配置为至少基于DCI的第一特定字段确定HARQ进程(HARQ process)的反馈机制是否被关闭，其中，在确定HARQ process的反馈机制被关闭的情况下，不向基站反馈针对数据包的校验结果。
其中，获取单元101和确定单元102可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。并且，应该理解，图1中所示的装置中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。
电子设备100例如可以设置在用户设备(UE)侧或者可通信地连接到UE。这里，还应指出，电子设备100可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备100可以工作为用户设备本身，并且还可以包括诸如存储器、收发器(图中未示出)等外部设备。存储器可以用于存储用户设备实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，基站、其他用户设备等等)间的通信，这里不具体限制收发器的实现形式。这同样适用于随后关于用户设备侧的电子设备的其他配置示例的描述。
此外，应该注意，本文中的第一、第二、……仅是为了区分的目的，而不存在任何顺序上的含义。
本实施例基于DCI进行HARQ反馈机制的关闭/开启，可以实现数据包级别的控制，例如，可以根据RTD大小、数据业务要求、具体通信 流程等来动态开启/关闭HARQ反馈机制，从而提高灵活度和系统效率。
在UE配置有多个HARQ进程的情况下，上述HARQ反馈机制的关闭/开启是针对其中一个HARQ进程(例如，由HARQ process序号识别)的，即，可以对各个HARQ进程的反馈机制单独地进行动态开启/关闭。
应该注意，当HARQ反馈机制被关闭时，为了保证系统可靠性，不排除使用HARQ盲传的可能性。HARQ盲传指的是在一定时间内，发送端多次重复发送相同的数据，而无需等待接收端的反馈。接收端把这段时间内多次接收到的数据包进行软合并，而无需针对每个数据包进行检验并反馈。
此外，本申请的实施例并不限制用户设备本身的行为，比如，在HARQ进程的反馈机制关闭时，作为接收端的用户设备可以清空对应HARQ进程的HARQ buffer以减小存储压力，也可以保留该HARQ进程的HARQ buffer中原有的数据以在重传时将多次传输的数据进行合并从而提高可靠性。另一方面，当HARQ进程的反馈机制被关闭时，用户设备可以针对数据包进行校验但是并不向基站反馈校验结果，也可以不针对数据包进行校验，取决于具体的实现形式。
例如，DCI的第一特定字段被设置用于指示HARQ进程的反馈机制是否被关闭，该第一特定字段被选择为使得在HARQ进程的反馈机制被关闭时仍支持HARQ盲传。例如，确定单元101被配置为当确定第一特定字段具有特定值时，确定HARQ进程的反馈机制被关闭。该特定值可以为预先确定的任意值，例如全0或全1。
示例性地，确定单元102可以基于无线资源控制(Radio Resource Control，RRC)信令来解析第一特定字段的含义，以执行所述确定。换言之，基站经由RRC信令来通知用户设备如下中的一个或多个：是否要执行HARQ进程的反馈机制的动态开启/关闭；用于指示HARQ进程的反馈机制被关闭的第一特定字段的特定值是多少。
可替选地，确定单元102也可以基于固有配置来解析第一特定字段的含义。例如，在要执行HARQ进程的反馈机制的动态开启/关闭的情况下，用于确定HARQ进程的反馈机制被关闭的第一特定字段的特定值的取值在出厂时写入到用户设备中。
作为一个示例，第一特定字段可以为PDSCH-to-HARQ_feedback timing indicator。该字段是DCI中的已有字段。在5G NR的调度中，针对每个HARQ进程的ACK/NACK的反馈时间由相应DCI中的PDSCH-to-HARQ_feedback timing indicator进行动态指示。例如，UE被连续调度接收两个PDSCH，针对第一个PDSCH(对应于HARQ process#1)的HARQ反馈时间由调度第一个PDSCH的DCI中的PDSCH-to-HARQ_feedback timing indicator确定，针对第二个PDSCH(对应于HARQ process#2)的HARQ反馈时间由调度第二个PDSCH的DCI中的PDSCH-to-HARQ_feedback timing indicator确定。
例如，对于DCI格式1_0，PDSCH-to-HARQ_feedback timing indicator字段的值映射到列表{1，2，3，4，5，6，7，8}；对于DCI格式1_1，PDSCH-to-HARQ_feedback timing indicator字段的值映射到由高层参数dl-DataToUL-ACK提供的一组时隙数(k)的值，如图2所示，其中dl-DataToUL-ACK是发送ACK/NACK的定时的列表。
例如，用户设备在第n个时隙收到PDSCH，如果PDSCH-to-HARQ_feedback timing indicator映射到值k，则用户设备在第n+k个时隙反馈对应于该PDSCH的校验结果比如ACK/NACK。
在本示例中，如果PDSCH-to-HARQ_feedback timing indicator的值为特定值比如全0或全1(不限于此)，其不再指示HARQ反馈时间，而是指示HARQ进程的反馈机制被关闭，用户设备不进行ACK/NACK的反馈。
例如，确定单元102可以基于RRC信令中的参数dl-DataToUL-ACK来确定第一特定字段的含义，其中，dl-DataToUL-ACK预留有一个状态用于指示当第一特定字段取特定值时HARQ进程的反馈机制被关闭。
图3示出了第一特定字段为PDSCH-to-HARQ_feedback timing indicator的情况下，其与时隙数之间的映射关系的示例。可以看出，在该示例中，特定值的示例为全0，当PDSCH-to-HARQ_feedback timing indicator取值为全0时，映射到dl-DataToUL-ACK的保留状态，指示HARQ进程的反馈机制被关闭；而当PDSCH-to-HARQ_feedback timing indicator取值不为全0时，要延迟的时隙数为映射到dl-DataToUL-ACK的其他状态所对应的不同的时隙数。
此外，dl-DataToUL-ACK的所预留的状态还可以用于指示HARQ进程的反馈机制被开启时第一特定字段的基准值。其中，该基准值用于补充HARQ进程的反馈机制被开启时第一特定字段的含义。
在第一特定字段为PDSCH-to-HARQ_feedback timing indicator的情况下，该基准值为基准时隙数，在计算用于反馈的时隙时，将该基准值加到第一特定字段所映射到的时隙数上。图4示出了PDSCH-to-HARQ_feedback timing indicator与时隙数之间的映射关系的另一个示例。其中，特定值的示例为全0，当PDSCH-to-HARQ_feedback timing indicator取值为全0时，映射到dl-DataToUL-ACK的保留状态，指示HARQ进程的反馈机制被关闭，同时，该保留状态还指示了PDSCH-to-HARQ_feedback timing indicator的基准值。当PDSCH-to-HARQ_feedback timing indicator取值不为全0时，真正要延迟的时隙数为映射到dl-DataToUL-ACK的其他状态所对应的不同的时隙数加上该基准值。
该基准值例如可以基于卫星波束到达地面的最小距离计算得到。具体地，假设卫星波束到达地面的最小距离为d，在透传(transparent)架构下，d’＝2＊d为最短距离；在再传(regenerative)架构下，d’＝d)，光速为c，子载波间隔(Sub carrier spacing，SCS)为15KHz＊2 k(k＝0，1，2，3，4)，则时隙数的基准值可由下式获得：
Figure PCTCN2020107687-appb-000001
图4的示例中基准值为16，假设PDSCH-to-HARQ_feedback timing indicator取值为“001”，且状态“001”对应的时隙数k为10，如果用户设备在时隙n处接收到PDSCH，则将在时隙n+26(即，n+10+16)处发送反馈ACK/NACK。
此外，上述基准值也可以作为DCI格式1_0中指示的PDSCH-to-HARQ_feedback timing indicator的基准值，例如PDSCH-to-HARQ_feedback timing indicator字段的值映射到列表{1，2，3，4，5，6，7，8}中的7，则如果用户设备在时隙n处接收到PDSCH，则将在时隙n+17(即，n+10+7)处发送反馈ACK/NACK。
本实施例的电子设备100还可以实现对半静态调度(semi-persistent  scheduling，SPS)数据的HARQ进程的反馈机制的动态开启/关闭。例如，第一特定字段可以包含在用于半静态调度(semi-persistent scheduling，SPS)激活或释放的DCI中，以实现对半静态调度数据的HARQ进程的反馈机制的开启/关闭。具体示例将在后文中参照图7给出。
此外，在确定第一特定字段不存在或者缺省时，确定单元102可以基于dl-DataToUL-ACK的预留的状态的取值来确定HARQ进程的反馈机制是否被关闭。例如，当预留的状态的取值为0或者小于特定取值时，确定单元102确定HARQ进程的反馈机制被关闭。该特定取值例如可以由基站通过RRC信令指示给用户设备，或者是默认值。这样，可以通过RRC信令实现对HARQ进程的反馈机制的半静态开启/关闭。
作为另一个示例，确定单元102可以基于第一特定字段与其他特定字段的组合来确定HARQ进程的反馈机制是否被关闭，例如，在确定组合的取值满足预定条件时，确定HARQ进程的反馈机制被关闭。
例如，第一特定字段为PDSCH-to-HARQ_feedback timing indicator，其他特定字段可以包括以下中的一个或多个：PUCCH resource indicator，TPC command for scheduled PUCCH。
在组合包括PDSCH-to-HARQ_feedback timing indicator、PUCCH resource indicator和TPC command for scheduled PUCCH的情况下，例如，预定条件可以包括如下之一：组合中的每一个字段取值均为全0；组合中的每一个字段取值均为全1；组合中的一部分字段取值为全0，其他字段取值为全1。注意，这里描述的预定条件仅是一个示例，可以应用的预定条件不限于此。
通过使用字段组合来指示HARQ进程的反馈机制是否被关闭，可以进一步提高可靠性。
通过本实施例，可以在不增加额外的信令开销的情况下实现HARQ进程的反馈机制的动态开启/关闭以及/或者半静态开启/关闭，提高了控制灵活性，进而提高了系统效率。此外，由于本实施例的方案支持HARQ进程的反馈机制关闭的情况下的HARQ盲传，因此保证了系统可靠性。
<第二实施例>
图5示出了根据本申请的另一个实施例的电子设备200的功能模块框图，如图5所示，电子设备200包括：生成单元201，被配置为生成DCI，DCI包括至少第一特定字段用于指示是否关闭HARQ进程的反馈机制；以及提供单元202，被配置为将DCI提供给用户设备，其中，在关闭HARQ进程的反馈机制的情况下，用户设备不向基站反馈针对数据包的校验结果。
其中，生成单元201和提供单元202可以由一个或多个处理电路实现，该处理电路例如可以实现为芯片。并且，应该理解，图5中所示的装置中的各个功能单元仅是根据其所实现的具体功能而划分的逻辑模块，而不是用于限制具体的实现方式。
电子设备200例如可以设置在基站侧或者可通信地连接到基站。这里，还应指出，电子设备200可以以芯片级来实现，或者也可以以设备级来实现。例如，电子设备200可以工作为基站本身，并且还可以包括诸如存储器、收发器(未示出)等外部设备。存储器可以用于存储基站实现各种功能需要执行的程序和相关数据信息。收发器可以包括一个或多个通信接口以支持与不同设备(例如，用户设备、其他基站等等)间的通信，这里不具体限制收发器的实现形式。
例如，生成单元201可以通过将第一特定字段的值设置为特定值，来指示关闭HARQ进程的反馈机制。该特定值例如为全0或全1，或者任何其他预定值。关于第一特定字段取特定值时关闭HARQ进程的反馈机制的规则可以在出厂时写入用户设备，从而用户设备在接收到特定值的第一特定字段时即可确定HARQ进程的反馈机制被关闭；或者，该规则可以经由RRC信令来通知用户设备，具体示例将在后文中描述。
其中，生成单元201可以被配置为根据如下中的至少一个来确定第一特定字段的值，即，确定是否将第一特定字段设置为特定值：基站与用户设备之间的往返时延(RTD)，业务要求，数据类型。当基站与用户设备之间的RTD较大时(比如大于预定阈值)，例如，当基站为地球同步轨道(Geostationary Earth Orbit，GEO)卫星时，关闭HARQ进程的反馈机制，即，将第一特定字段设置为特定值；当基站为低地球轨道(Low Earth Orbit，LEO)卫星时，开启HARQ进程的反馈机制，即，不将第一特定字段设置为特定值。对于可靠性要求不高的数据，可以关闭HARQ进程的反馈机制；对于可靠性要求高的数据，则开启HARQ 进程的反馈机制。此外，对于控制平面数据，可以开启HARQ进程的反馈机制，例如，对于初始接入过程则开启HARQ进程的反馈机制，用户设备正常接入系统后，则关闭HARQ进程的反馈机制。应该注意，在关闭HARQ进程的反馈机制时，仍然支持HARQ盲传。
在第一特定字段包含在用于半静态调度的激活或释放的DCI中的情况下，可以实现对半静态调度数据的HARQ进程的反馈机制的动态开启/关闭。
作为一个示例，第一特定字段为PDSCH-to-HARQ_feedback timing indicator。
生成单元201还可以被配置为在RRC信令中的参数dl-DataToUL-ACK中预留一个状态用于指示当第一特定字段取特定值时关闭HARQ进程的反馈机制。即，关闭HARQ进程的反馈机制的规则通过RRC信令来通知用户设备。如第一实施例中所述，dl-DataToUL-ACK是发送ACK/NACK的定时的列表，其指示了当PDSCH-to-HARQ_feedback timing indicator取不同值时发送ACK/NACK反馈的定时。在本实施例中，在dl-DataToUL-ACK中预留一个状态，当PDSCH-to-HARQ_feedback timing indicator取特定值时映射到该预留状态，根据该预留状态，用户设备确定HARQ进程的反馈机制被关闭。当PDSCH-to-HARQ_feedback timing indicator不取特定值时，映射到dl-DataToUL-ACK的其他状态，根据这些状态，用户设备确定要发送ACK/NACK反馈的定时，具体示例可参见附图3以及第一实施例中的相关描述。
另外，dl-DataToUL-ACK的所预留的状态还可以用于指示开启HARQ进程的反馈机制时第一特定字段的基准值。其中，该基准值用于补充HARQ进程的反馈机制被开启时第一特定字段的含义。
在第一特定字段为PDSCH-to-HARQ_feedback timing indicator的情况下，在计算用于反馈的时隙时，将该基准值加到第一特定字段所映射到的时隙数上。具体示例可参见附图4以及第一实施例中的相关描述，在此不再重复。该基准值例如可以基于卫星波束到达地面的最小距离计算得到，如前式(1)所示。
示例性地，生成单元201还可以省略第一特定字段或者将第一特定 字段设置为缺省值，并将dl-DataToUL-ACK的所预留的状态的取值设置为0或小于特定取值来指示关闭HARQ进程的反馈机制。在这种情况下，可以通过RRC信令实现对HARQ进程的反馈机制的半静态关闭/开启。
在另一个示例中，DCI包括第一特定字段和其他特定字段的组合来指示是否关闭HARQ进程的反馈机制。例如，第一特定字段为PDSCH-to-HARQ_feedback timing indicator，其他特定字段包括以下中的一个或多个：PUCCH resource indicator，TPC command for scheduled PUCCH。
在组合包括PDSCH-to-HARQ_feedback timing indicator、PUCCH resource indicator和TPC command for scheduled PUCCH的情况下，例如，生成单元201可以将组合的取值设置为如下之一来指示关闭HARQ进程的反馈机制：组合中的每一个字段取值均为全0；组合中的每一个字段取值均为全1；组合中的一部分字段取值为全0，其他字段取值为全1。注意，这里描述的取值设置仅是示例，而不是限制性的。
通过使用字段组合来指示是否关闭HARQ进程的反馈机制，可以进一步提高可靠性。
通过本实施例，可以在不增加额外的信令开销的情况下实现HARQ进程的反馈机制的动态开启/关闭以及/或者半静态开启/关闭，提高了控制灵活性，进而提高了系统效率。此外，由于本实施例的方案支持HARQ进程的反馈机制关闭的情况下的HARQ盲传，因此保证了系统可靠性。
为了便于理解，图6示出了在用于动态调度数据的HARQ进程的反馈机制的动态开启/关闭的情况下基站与用户设备之间的信息流程的示例的示意图。如图6所示，在用户设备(UE)初始接入基站(BS)之后，基站可以通过DCI中的PDSCH-to-HARQ_feedback timing indicator字段在数据包级别上进行HARQ的关闭/开启。在图6的示例中，BS在发送通过C-RNTI扰码的PDCCH和对应的PDSCH#1(这里“对应的PDSCH#1”指被该PDCCH通过DCI调度的PDSCH，以下相应的PDSCH同理)时，将DCI中的PDSCH-to-HARQ_feedback timing indicator设置为全0。UE对PDCCH和PDSCH#1进行解码，并基于PDSCH-to-HARQ_feedback timing indicator为全0这一事实确定不需要进行校验结果的反馈，其中，UE是否要执行CRC取决于具体的UE实 现，并不是限制性的。接着，BS在发送通过C-RNTI扰码的PDCCH和对应的PDSCH#2时，将DCI中的PDSCH-to-HARQ_feedback timing indicator设置为非全0。类似地，UE对PDCCH和PDSCH#2进行解码，并基于PDSCH-to-HARQ_feedback timing indicator为非全0这一事实确定需要进行校验结果的反馈。例如，UE基于CRC结果向BS反馈NACK，BS接收到NACK后再次发送PDSCH#2，UE再次进行解码并执行CRC。如果CRC结果正确，则UE向BS反馈ACK。随后，执行其他数据包的传输。
此外，图7示出了在用于半静态调度(SPS)数据的HARQ进程的反馈机制的动态开启/关闭的情况下基站与用户设备之间的信息流程的示例的示意图。如图7所示，在UE初始接入BS之后，BS在发送通过CS-RNTI扰码的用于SPS激活的DCI和对应的PDSCH#1时，将DCI中的PDSCH-to-HARQ_feedback timing indicator设置为全0。UE对PDCCH和PDSCH#1进行解码，并基于PDSCH-to-HARQ_feedback timing indicator为全0这一事实确定不需要进行校验结果的反馈，其中，UE是否要执行CRC取决于具体的UE实现，并不是限制性的。接着，BS继续发送SPS数据PDSCH#2和PDSCH#3，由于SPS被激活的DCI中PDSCH-to-HARQ_feedback timing indicator是全0，因此延续之前的HARQ进程的反馈机制的状态，UE对于PDSCH#2和PDSCH#3也不执行ACK/NACK反馈。随后，BS发送通过CS-RNTI扰码的用于SPS释放的DCI并将其中的PDSCH-to-HARQ_feedback timing indicator设置为非全0，UE根据PDSCH-to-HARQ_feedback timing indicator的指示针对该SPS释放反馈ACK。接下来，BS在发送通过CS-RNTI扰码的用于SPS激活的DCI和对应的PDSCH#4时，将DCI中的PDSCH-to-HARQ_feedback timing indicator设置为非全0。UE对PDCCH和PDSCH#4进行解码，并基于PDSCH-to-HARQ_feedback timing indicator为非全0这一事实进行校验结果的反馈。BS随后发送PDSCH#5，由于SPS被激活的DCI中PDSCH-to-HARQ_feedback timing indicator是非全0，因此延续之前的HARQ进程的反馈机制的状态，UE对于PDSCH#5执行校验结果(图7的示例中为ACK)的反馈。
应该注意，图6和7中的信息流程仅是示意性的，并不对本申请构成限制。
<第三实施例>
在上文的实施方式中描述用于无线通信的电子设备的过程中，显然还公开了一些处理或方法。下文中，在不重复上文中已经讨论的一些细节的情况下给出这些方法的概要，但是应当注意，虽然这些方法在描述用于无线通信的电子设备的过程中公开，但是这些方法不一定采用所描述的那些部件或不一定由那些部件执行。例如，用于无线通信的电子设备的实施方式可以部分地或完全地使用硬件和/或固件来实现，而下面讨论的用于无线通信的方法可以完全由计算机可执行的程序来实现，尽管这些方法也可以采用用于无线通信的电子设备的硬件和/或固件。
图8示出了根据本申请的一个实施例的用于无线通信的方法的流程图，该方法包括：从基站获取DCI(S11)；以及至少基于DCI的第一特定字段确定HARQ进程的反馈机制是否被关闭(S12)，其中，在确定HARQ进程的反馈机制被关闭的情况下，不向基站反馈针对数据包的校验结果。
在步骤S12中，例如，当确定第一特定字段具有特定值时，确定HARQ进程的反馈机制被关闭。特定值的示例例如为全0或全1，但并不限于此。在步骤S12中，可以基于RRC信令来解释第一特定字段的含义，以执行上述确定。或者，也可以基于出厂设置来解释第一特定字段的含义。
例如，在步骤S12中可以基于RRC信令中的参数dl-DataToUL-ACK来确定第一特定字段的含义，其中，dl-DataToUL-ACK预留有一个状态用于指示当第一特定字段取特定值时HARQ进程的反馈机制被关闭。此外，dl-DataToUL-ACK的所预留的状态还用于指示HARQ进程的反馈机制被开启时第一特定字段的基准值。
在第一特定字段不存在或者缺省时，还可以基于dl-DataToUL-ACK的所预留的状态的取值来确定HARQ进程的反馈机制是否被关闭。当所预留的状态的取值为0或小于特定取值时，确定HARQ进程的反馈机制被关闭。
作为一个示例，第一特定字段为PDSCH-to-HARQ_feedback timing indicator。
在步骤S12中，还可以基于第一特定字段与其他特定字段的组合来确定HARQ进程的反馈机制是否被关闭，并且当确定所述组合的取值满足预定条件时，确定HARQ进程的反馈机制被关闭。
例如，第一特定字段为PDSCH-to-HARQ_feedback timing indicator，其他特定字段包括以下中的一个或多个：PUCCH resource indicator，TPC command for scheduled PUCCH。在组合包括PDSCH-to-HARQ_feedback timing indicator、PUCCH resource indicator和TPC command for scheduled PUCCH的情况下，预定条件可以包括以下之一：组合中的每一个字段取值均为全0，组合中的每一个字段取值均为全1，组合中的一部分字段取值为全0，其他字段取值为全1。
图9示出了根据本申请的另一个实施例的用于无线通信的方法的流程图，该方法包括：生成DCI，DCI包括至少第一特定字段用于指示是否关闭HARQ进程的反馈机制(S21)；以及将DCI提供给用户设备(S22)，其中，在关闭HARQ进程的反馈机制的情况下，用户设备不向基站反馈针对数据包的校验结果。
在步骤S21中，可以根据如下中的至少一个来确定第一特定字段的值：基站与用户设备之间的往返时延，业务要求，数据类型。
例如，在步骤S21中，可以通过将第一特定字段的值设置为特定值，来指示关闭HARQ进程的反馈机制。此外，还可以在RRC信令中的参数dl-DataToUL-ACK中预留一个状态用于指示当第一特定字段取特定值时关闭HARQ进程的反馈机制。dl-DataToUL-ACK的所预留的状态还可以用于指示开启HARQ进程的反馈机制时第一特定字段的基准值。
还可以省略第一特定字段或者将第一特定字段设置为缺省值，并将dl-DataToUL-ACK的所预留的状态的取值设置为0或小于特定取值来指示关闭HARQ进程的反馈机制。
此外，DCI可以包括第一特定字段和其他特定字段的组合来指示是否关闭HARQ进程的反馈机制。
作为一个示例，第一特定字段可以为PDSCH-to-HARQ_feedback timing indicator。其他特定字段可以包括以下中的一个或多个：PUCCH resource indicator，TPC command for scheduled PUCCH。
在步骤S21中可以对PDSCH-to-HARQ_feedback timing indicator、PUCCH resource indicator和TPC command for scheduled PUCCH的取值进行如下之一的设置以指示关闭HARQ进程的反馈机制：均为全0，均为全1，一部分为全0且另一部分为全1。
