Description

混合自动重传请求反馈方法及装置、用户设备和基站 技术领域
本公开涉及通信技术领域，尤其涉及一种混合自动重传请求反馈方法及装置、判断数据传输成败的方法及装置、用户设备、基站和计算机可读存储介质。
背景技术
第五代移动通信技术(5th Generation，简称为5G)新空口(NR)非授权(unlicensed)应用是5G发展的一个重要应用场景，即将5G NR的传输应用在非授权频段(unlicensed spectrum)中，所谓非授权频段是指不用授权就可以免费使用的频段。常见的无线保真(WiFi)就运行在非授权频段中。
非授权频段由于不受运营商部署网络的管制，因此其应用节点(AP)需要克服其他应用节点的传输带来的干扰问题。最常见的方式是在非授权频段中划分出不同的信道，AP在使用某个信道进行传输时，先监听该信道是否有其他的传输，如果没有，则开始自己的传输，也就是常说的先听后发(License Before Talk，简称LBT)机制。WiFi就是典型的使用LBT机制的系统。
5G NR unlicensed传输在非授权频段的使用也同样面临其他系统传输对自己的干扰问题，例如，当在某个信道占用时间(Channel Occupation Time，简称COT)内大部分是下行控制(Dc)和下行传输(Dd)，在COT的结尾有一次上行传输的机会，UE可以反馈下行传输的确认(ACK)或不确认(NACK)。然而，由于LBT机制的存在，这个唯一上行传输的机会有可能因为其他系统在传输而被错过，那么如何在可能丢失上行传输的情况下完成ACK或NACK传输是需要解决的一个技术问题。

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。
图1是本申请一示例性实施例示出的一种HARQ反馈方法的流程图，该实施例从UE侧进行描述，如图1所示，该HARQ反馈方法包括：
在步骤S101中，若监听到当前时频资源位置正在传输其他UE的信号，则缓存待反馈的HARQ反馈信息。
在步骤S102中，根据多个预设频段的优先级在多个预设频段的预设时频资源位置发送HARQ反馈信息。
可选地，在步骤S102之前，该方法还可以包括：接收基站发送的多个预设频段的优先级以及多个预设频段的预设时频资源位置，该预设频段可以包括但不局限于聚合载波(component carrier，简称CC)、带宽部分(BWP)等，该预设时频资源位置用于发送HARQ反馈信息。
其中，多个预设频段的频率跨度可以随着优先级的降低而增加，例如，假设基站发送的多个预设频段为CC1、CC2和CC3，每个CC均包括3个BWP，即BWP1～BWP3。其中，CC2的BWP2为第一优先级，CC2的BWP1和BWP3为第二优先级，CC1的BWP2和CC3的BWP2为第三优先级，则第二优先级的BWP1和BWP3之间的频率跨度是20MHz，第三优先级的CC1的BWP2和CC3的BWP2之间的频率跨度是40MHz等，直到达到某个预设频率跨度的上限为止，该预设频率跨度的上限往往是射频模块的能力上限。通过设置多个预设频段的频率跨度随着优先级的降低而增加，可以逐步且有效地扩大频率选择的范围，以在有 限次数的尝试里增加反馈成功的概率。
在该实施例中，若UE监听到当前时频资源位置正在传输其他UE的信号，则缓存待反馈的HARQ反馈信息，并根据多个预设频段的优先级在多个预设频段的预设时频资源位置发送HARQ反馈信息。
其中，根据多个预设频段的优先级在多个预设频段的预设时频资源位置发送HARQ反馈信息，可以包括但不局限于以下任一方式：
方式11)在最高优先级对应的预设频段的预设时频资源位置发送HARQ反馈信息，若HARQ反馈信息发送失败，则在下一个优先级对应的预设频段的预设时频资源位置发送HARQ反馈信息，直至发送成功或通过所有预设频段的预设时频资源位置发送过HARQ反馈信息。
假设基站发送的多个预设频段为CC1、CC2和CC3，每个CC均包括3个BWP，即BWP1～BWP3。如图2所示，CC2的BWP2为第一优先级，CC2的BWP1和BWP3为第二优先级，CC1的BWP2和CC3的BWP2为第三优先级。其中，每个频段的预设时频资源位置为图2中的位置22、23、24、25和26。例如，UE在CC2的BWP2上有一段下行传输，如图2中的位置21，但其对应的上行传输在位置22由于LBT受阻，UE检测到上行传输受阻后，UE缓存待反馈的HARQ反馈信息，并在预设的下一个优先级的预设频段的预设时频资源位置即图2中位置23和24发送HARQ反馈信息，如果UE再次检测到CC2的BWP1、BWP2、BWP3的反馈资源因LBT受阻，则再次在预设的下一个优先级的预设频段的预设时频资源位置即图2中的位置25和26发送HARQ反馈信息。
方式12)按照优先级由高到低的顺序确定多个预设频段的预设时频资源位置的集合，按照所确定的集合的顺序在对应的多个预设频段的预设时频资源位置发送HARQ反馈信息，直至发送成功或通过所有预设频段的预设时频资源位置发送过HARQ反馈信息。
例如，可以按照优先级由高到低的顺序将每两个优先级对应的预设频段的预设时频资源位置作为一个集合。继续以图2为例，可以将第一优先级和第二优先级对应的预设频段的预设时频资源位置作为一个集合，将第三优先级对应的预设频段的预设时频资源位置作为一个集合，这样，UE最开始就可以尝试在图2所示的位置22、23和24发送HARQ反馈信息，基站在这多个位置尝试读取HARQ反馈信息，只要有一个位置成功读取，则可认为成功反馈。
另外，可选地，当该HARQ反馈信息与其他HARQ反馈信息通过同一预设频段的同一预设时频资源位置发送时，可以对该HARQ反馈信息和其他HARQ反馈信息进行绑定操 作，并在同一预设频段的同一预设时频资源位置发送绑定后的信息。
例如，UE在图2所示的位置22、23和24发送HARQ反馈信息，而这三个位置本应有其对应的下行传输需要反馈。当发生此类冲突时，可以采用与或运算，将多个HARQ反馈信息绑定，以减少HARQ反馈信息的传输量。
可选地，该方法还可以包括：当根据多个预设频段的优先级在多个预设频段的预设时频资源位置发送HARQ反馈信息时，对于没有数据传输的预设频段，不开启对应的射频模块，以节省UE的功耗，从而节省UE的电量。
其中，频段的优先级可能受射频器件的能力影响，例如，第一优先级的CC是射频模块1支持的CC，第二优先级的CC是射频模块2支持的CC，当在第二优先级的CC上没有数据传输时，不需要开启射频模块2。
可选地，该方法还可以包括：若接收到基站发送的HARQ反馈成功确认信息，则停止发送HARQ反馈信息。
例如，UE在图2中的位置22、23和24中的任意一个位置成功发送了HARQ反馈信息，则基站在下一个传输单元(例如slot)的PDCCH的下行控制信令中携带HARQ反馈成功确认信息，这样，UE就不需要在位置25和26发送HARQ反馈信息。
另外，可选地，当UE根据被配置的优先级在一定时间范围内尝试了所有可能的预设时频资源位置后，或尝试了所有可能的预设时频资源位置的一定次数后，则停止尝试。
上述实施例，若监听到当前时频资源位置正在传输其他UE的信号，则缓存待反馈的HARQ反馈信息，并根据多个预设频段的优先级在多个预设频段的预设时频资源位置发送HARQ反馈信息，以实现在非授权频段进行HARQ反馈受阻时，在不同频域位置上进行HARQ反馈，从而提高反馈成功的概率。
图3是本申请一示例性实施例示出的一种判断数据传输成败的方法的流程图，该实施例从基站侧进行描述，如图3所示，该方法包括：
在步骤S301，按照多个预设频段对应的优先级由高到低的顺序在对应的预设时频资源位置接收UE发送的HARQ反馈信息。
可选地，在步骤S301之前，该方法还可以包括：为UE配置多个预设频段的优先级以及多个预设频段的预设时频资源位置，向UE发送多个预设频段的优先级以及多个预设频段的预设时频资源位置。例如，可以通过广播信令、物理层控制信令、上层RRC信令或媒体 接入控制(MAC)控制元素(CE)信令向UE发送多个预设频段的优先级以及多个预设频段的预设时频资源位置。
该预设频段可以包括但不局限于聚合载波(component carrier，简称CC)、带宽部分(BWP)等，该预设时频资源位置用于发送HARQ反馈信息。
其中，多个预设频段的频率跨度可以随着优先级的降低而增加，例如，假设基站发送的多个预设频段为CC1、CC2和CC3，每个CC均包括3个BWP，即BWP1～BWP3。其中，CC2的BWP2为第一优先级，CC2的BWP1和BWP3为第二优先级，CC1的BWP2和CC3的BWP2为第三优先级，则第二优先级的BWP1和BWP3之间的频率跨度是20MHz，第三优先级的CC1的BWP2和CC3的BWP2之间的频率跨度是40MHz等，直到达到某个预设频率跨度的上限为止，该预设频率跨度的上限往往是射频模块的能力上限。通过设置多个预设频段的频率跨度随着优先级的降低而增加，可以逐步且有效地扩大频率选择的范围，以使UE在有限次数的尝试里增加反馈成功的概率。
在步骤S302，根据接收到的HARQ反馈信息判断对应数据的传输成败。
其中，根据接收到的HARQ反馈信息判断对应数据的传输成败可以包括以下任一方式：
方式21)获取接收到的多个HARQ反馈信息对应的预设频段的优先级，从所获取的优先级中确定最高优先级，根据确定的最高优先级对应的HARQ反馈信息判断对应数据的传输成败。
方式22)对接收到的多个HARQ反馈信息的比特bit值进行投票，根据票数多的bit值判断对应数据的传输成败。
对于这种方式，不考虑优先级，对接收到的所有HARQ反馈信息的比特bit值进行投票，如果bit值为1的HARQ反馈信息的数量多于bit值为0的HARQ反馈信息的数量，就认为HARQ反馈信息的bit值为1，如果bit值为1的HARQ反馈信息的数量等于bit值为0的HARQ反馈信息的数量，就认为bit值为0。
方式23)获取接收到的多个HARQ反馈信息对应的预设频段的优先级，从所获取的优先级中确定排名在前的预设数量的优先级，对排名在前的预设数量的优先级对应的多个HARQ反馈信息的bit值进行投票，根据票数多的bit值判断对应数据的传输成败。
例如，获取接收到的多个HARQ反馈信息对应的预设频段的优先级为第二优先级和第三优先级，其中，第二优先级对应的HARQ反馈信息有3个，第三优先级对应的HARQ 反馈信息有2个，则可以对第二优先级的3个HARQ反馈信息的bit值进行投票(忽略第三优先级对应的HARQ反馈信息)，根据票数多的bit值判断对应数据的传输成败。
可选地，该方法还可以包括：若成功读取到HARQ反馈信息，则向UE发送HARQ反馈成功确认信息，以使UE根据HARQ反馈成功确认信息不再发送HARQ反馈信息。其中，可以通过物理层控制信令、上层RRC信令或MAC CE信令向UE发送HARQ反馈成功确认信息。
上述实施例，通过按照多个预设频段对应的优先级由高到低的顺序在对应的预设时频资源位置接收UE发送的HARQ反馈信息，提高了接收到HARQ反馈信息的概率，并根据接收到的HARQ反馈信息判断对应数据的传输成败，从而可以及时判断数据的传输成败。
图4是本申请一示例性实施例示出的一种判断数据传输成败的方法的信令流程图，该实施例从基站和UE交互的角度进行描述，如图4所示，该方法包括：
在步骤S401中，基站为UE配置多个预设频段的优先级以及多个预设频段的预设时频资源位置，向UE发送多个预设频段的优先级以及多个预设频段的预设时频资源位置。
在步骤S402中，UE接收多个预设频段的优先级以及多个预设频段的预设时频资源位置。
在步骤S403中，若UE监听到当前时频资源位置正在传输其他UE的信号，则缓存待反馈的HARQ反馈信息。
在步骤S404中，UE根据多个预设频段的优先级在多个预设频段的预设时频资源位置发送HARQ反馈信息。
在步骤S405，基站按照多个预设频段对应的优先级由高到低的顺序在对应的预设时频资源位置接收UE发送的HARQ反馈信息。
在步骤S406，基站根据接收到的HARQ反馈信息判断对应数据的传输成败。
上述实施例，通过基站和UE之间的交互，使得UE可以在非授权频段进行HARQ反馈受阻时，在不同频域位置上进行HARQ反馈，从而提高反馈成功的概率，使得基站可以根据接收到的HARQ反馈信息判断对应数据的传输成败，从而可以及时判断数据的传输成败。
图5是根据一示例性实施例示出的一种HARQ反馈装置的框图，该装置可以位于UE中，如图5所示，该装置包括：
监听缓存模块51被配置为若监听到当前时频资源位置正在传输其他UE的信号，则 缓存待反馈的HARQ反馈信息。
发送模块52被配置为根据多个预设频段的优先级在多个预设频段的预设时频资源位置发送监听缓存模块51缓存的HARQ反馈信息。
该预设频段可以包括但不局限于聚合载波(component carrier，简称CC)、带宽部分(BWP)等，该预设时频资源位置用于发送HARQ反馈信息。
其中，多个预设频段的频率跨度可以随着优先级的降低而增加，例如，假设基站发送的多个预设频段为CC1、CC2和CC3，每个CC均包括3个BWP，即BWP1～BWP3。其中，CC2的BWP2为第一优先级，CC2的BWP1和BWP3为第二优先级，CC1的BWP2和CC3的BWP2为第三优先级，则第二优先级的BWP1和BWP3之间的频率跨度是20MHz，第三优先级的CC1的BWP2和CC3的BWP2之间的频率跨度是40MHz等，直到达到某个预设频率跨度的上限为止，该预设频率跨度的上限往往是射频模块的能力上限。通过设置多个预设频段的频率跨度随着优先级的降低而增加，可以逐步且有效地扩大频率选择的范围，以在有限次数的尝试里增加反馈成功的概率。
在该实施例中，若UE监听到当前时频资源位置正在传输其他UE的信号，则缓存待反馈的HARQ反馈信息，并根据多个预设频段的优先级在多个预设频段的预设时频资源位置发送HARQ反馈信息。
可选地，发送模块52可以被配置为当HARQ反馈信息与其他HARQ反馈信息通过同一预设频段的同一预设时频资源位置发送时，对HARQ反馈信息和其他HARQ反馈信息进行绑定操作，并在同一预设频段的同一预设时频资源位置发送绑定后的信息。
例如，UE在图2所示的位置22、23和24发送HARQ反馈信息，而这三个位置本应有其对应的下行传输需要反馈。当发生此类冲突时，可以采用与或运算，将多个HARQ反馈信息绑定，以减少HARQ反馈信息的传输量。
上述实施例，若监听到当前时频资源位置正在传输其他UE的信号，则缓存待反馈的HARQ反馈信息，并根据多个预设频段的优先级在多个预设频段的预设时频资源位置发送HARQ反馈信息，以实现在非授权频段进行HARQ反馈受阻时，在不同频域位置上进行HARQ反馈，从而提高反馈成功的概率。
图6是根据一示例性实施例示出的另一种HARQ反馈装置的框图，如图6所示，在上述图5所示实施例的基础上，该装置还可以包括：
接收模块53被配置为在发送模块52根据多个预设频段的优先级在多个预设频段的预 设时频资源位置发送监听缓存模块缓存的HARQ反馈信息之前，接收基站发送的多个预设频段的优先级以及多个预设频段的预设时频资源位置，该预设时频资源位置用于发送HARQ反馈信息。
上述实施例，通过接收基站发送的多个预设频段的优先级以及多个预设频段的预设时频资源位置，从而为后续根据多个预设频段的优先级在多个预设频段的预设时频资源位置发送HARQ反馈信息提供了条件。
图7是根据一示例性实施例示出的另一种HARQ反馈装置的框图，如图7所示，在上述图5所示实施例的基础上，发送模块52可以包括：第一发送子模块521或者第二发送子模块522。
第一发送子模块521被配置为在最高优先级对应的预设频段的预设时频资源位置发送HARQ反馈信息，若HARQ反馈信息发送失败，则在下一个优先级对应的预设频段的预设时频资源位置发送HARQ反馈信息，直至发送成功或通过所有预设频段的预设时频资源位置发送过HARQ反馈信息。
假设基站发送的多个预设频段为CC1、CC2和CC3，每个CC均包括3个BWP，即BWP1～BWP3。如图2所示，CC2的BWP2为第一优先级，CC2的BWP1和BWP3为第二优先级，CC1的BWP2和CC3的BWP2为第三优先级。其中，每个频段的预设时频资源位置为图2中的位置22、23、24、25和26。例如，UE在CC2的BWP2上有一段下行传输，如图2中的位置21，但其对应的上行传输在位置22由于LBT受阻，UE检测到上行传输受阻后，UE缓存待反馈的HARQ反馈信息，并在预设的下一个优先级的预设频段的预设时频资源位置即图2中位置23和24发送HARQ反馈信息，如果UE再次检测到CC2的BWP1、BWP2、BWP3的反馈资源因LBT受阻，则再次在预设的下一个优先级的预设频段的预设时频资源位置即图2中的位置25和26发送HARQ反馈信息。
第二发送子模块522被配置为按照优先级由高到低的顺序确定多个预设频段的预设时频资源位置的集合，按照所确定的集合的顺序在对应的多个预设频段的预设时频资源位置发送HARQ反馈信息，直至发送成功或通过所有预设频段的预设时频资源位置发送过HARQ反馈信息。
例如，可以按照优先级由高到低的顺序将每两个优先级对应的预设频段的预设时频资源位置作为一个集合。继续以图2为例，可以将第一优先级和第二优先级对应的预设频段的预设时频资源位置作为一个集合，将第三优先级对应的预设频段的预设时频资源位置作为一 个集合，这样，UE最开始就可以尝试在图2所示的位置22、23和24发送HARQ反馈信息，基站在这多个位置尝试读取HARQ反馈信息，只要有一个位置成功读取，则可认为成功反馈。
上述实施例，通过多种方式发送HARQ反馈信息，实现手段灵活。
图8是根据一示例性实施例示出的另一种HARQ反馈装置的框图，如图8所示，在上述图5所示实施例的基础上，该装置还可以包括：
停止发送模块54被配置为若接收到基站发送的HARQ反馈成功确认信息，则停止发送HARQ反馈信息。
例如，UE在图2中的位置22、23和24中的任意一个位置成功发送了HARQ反馈信息，则基站在下一个传输单元(例如slot)的PDCCH的下行控制信令中携带HARQ反馈成功确认信息，这样，UE就不需要在位置25和26发送HARQ反馈信息。
上述实施例，若接收到基站发送的HARQ反馈成功确认信息，则停止发送HARQ反馈信息，以减少UE的功耗。
图9是根据一示例性实施例示出的另一种HARQ反馈装置的框图，如图9所示，在上述图5所示实施例的基础上，该装置还可以包括：
处理模块55被配置为当发送模块52根据多个预设频段的优先级在多个预设频段的预设时频资源位置发送HARQ反馈信息时，对于没有数据传输的预设频段，不开启对应的射频模块。
其中，频段的优先级可能受射频器件的能力影响，例如，第一优先级的CC是射频模块1支持的CC，第二优先级的CC是射频模块2支持的CC，当在第二优先级的CC上没有数据传输时，不需要开启射频模块2。
上述实施例，通过对于没有数据传输的预设频段，不开启对应的射频模块，以节省UE的功耗，从而节省UE的电量。
图10是根据一示例性实施例示出的一种判断数据传输成败的装置的框图，该装置可以位于基站中，如图10所示，该装置包括：
接收模块110被配置为按照多个预设频段对应的优先级由高到低的顺序在对应的预设时频资源位置接收用户设备UE发送的混合自动重传请求HARQ反馈信息。
该预设频段可以包括但不局限于聚合载波(component carrier，简称CC)、带宽部分(BWP)等，该预设时频资源位置用于发送HARQ反馈信息。
其中，多个预设频段的频率跨度可以随着优先级的降低而增加，例如，假设基站发送的多个预设频段为CC1、CC2和CC3，每个CC均包括3个BWP，即BWP1～BWP3。其中，CC2的BWP2为第一优先级，CC2的BWP1和BWP3为第二优先级，CC1的BWP2和CC3的BWP2为第三优先级，则第二优先级的BWP1和BWP3之间的频率跨度是20MHz，第三优先级的CC1的BWP2和CC3的BWP2之间的频率跨度是40MHz等，直到达到某个预设频率跨度的上限为止，该预设频率跨度的上限往往是射频模块的能力上限。通过设置多个预设频段的频率跨度随着优先级的降低而增加，可以逐步且有效地扩大频率选择的范围，以使UE在有限次数的尝试里增加反馈成功的概率。
判断模块120被配置为根据接收模块110接收到的HARQ反馈信息判断对应数据的传输成败。
上述实施例，通过按照多个预设频段对应的优先级由高到低的顺序在对应的预设时频资源位置接收UE发送的HARQ反馈信息，提高了接收到HARQ反馈信息的概率，并根据接收到的HARQ反馈信息判断对应数据的传输成败，从而可以及时判断数据的传输成败。
图11是根据一示例性实施例示出的另一种判断数据传输成败的装置的框图，如图11所示，在上述图10所示实施例的基础上，该装置还可以包括：
配置模块130被配置为在接收模块110按照多个预设频段对应的优先级由高到低的顺序在对应的预设时频资源位置接收UE发送的HARQ反馈信息之前，为UE配置多个预设频段的优先级以及多个预设频段的预设时频资源位置，上述预设时频资源位置用于发送HARQ反馈信息。
第一发送模块140被配置为向UE发送配置模块130配置的多个预设频段的优先级以及多个预设频段的预设时频资源位置。
其中，第一发送模块140可以通过广播信令、物理层控制信令、上层无线资源控制RRC信令或媒体接入控制MAC控制元素CE信令向UE发送多个预设频段的优先级以及多个预设频段的预设时频资源位置。
上述实施例，通过为UE配置多个预设频段的优先级以及多个预设频段的预设时频资源位置，并向UE发送配置的多个预设频段的优先级以及多个预设频段的预设时频资源位置，使得UE可以根据多个预设频段的优先级在多个预设频段的预设时频资源位置发送HARQ反馈信息。
图12是根据一示例性实施例示出的另一种判断数据传输成败的装置的框图，如图12 所示，在上述图10所示实施例的基础上，判断模块120可以包括：第一判断子模块1201、第二判断子模块1202或者第三判断子模块1203。
第一判断子模块1201被配置为获取接收到的多个HARQ反馈信息对应的预设频段的优先级，从所获取的优先级中确定最高优先级，根据确定的最高优先级对应的HARQ反馈信息判断对应数据的传输成败。
第二判断子模块1202被配置为对接收到的多个HARQ反馈信息的比特bit值进行投票，根据票数多的bit值判断对应数据的传输成败。
对于这种方式，不考虑优先级，对接收到的所有HARQ反馈信息的比特bit值进行投票，如果bit值为1的HARQ反馈信息的数量多于bit值为0的HARQ反馈信息的数量，就认为HARQ反馈信息的bit值为1，如果bit值为1的HARQ反馈信息的数量等于bit值为0的HARQ反馈信息的数量，就认为bit值为0。
第三判断子模块1203被配置为获取接收到的多个HARQ反馈信息对应的预设频段的优先级，从所获取的优先级中确定排名在前的预设数量的优先级，对排名在前的预设数量的优先级对应的多个HARQ反馈信息的bit值进行投票，根据票数多的bit值判断对应数据的传输成败。
例如，获取接收到的多个HARQ反馈信息对应的预设频段的优先级为第二优先级和第三优先级，其中，第二优先级对应的HARQ反馈信息有3个，第三优先级对应的HARQ反馈信息有2个，则可以对第二优先级的3个HARQ反馈信息的bit值进行投票(忽略第三优先级对应的HARQ反馈信息)，根据票数多的bit值判断对应数据的传输成败。
上述实施例，通过多种方式判断对应数据的传输成败，实现手段灵活多样。
图13是根据一示例性实施例示出的另一种判断数据传输成败的装置的框图，如图13所示，在上述图10所示实施例的基础上，该装置还可以包括：

其中，第二发送模块150可以被配置为：通过物理层控制信令、上层无线资源控制RRC信令或媒体接入控制MAC控制元素CE信令向UE发送HARQ反馈成功确认信息。
上述实施例，通过在成功读取到HARQ反馈信息时，向UE发送HARQ反馈成功确认信息，使得UE可以据此停止发送HARQ反馈信息，从而减少UE的功耗。
