Description
本申请要求在2018年3月21日提交中国专利局、申请号为201810233397.7，发明名称为“一种上行控制信息传输方法及设备”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。
本申请涉及无线通信技术领域，尤其涉及一种上行控制信息传输方法及设备。
5G作为移动通信的最新一代技术，那么基于5G的各种扩展、应用也将逐步蓬勃发展。其中，一个重要应用就是对非授权频段的使用。
无线电资源作为国家重要的战略资源，包含非授权频段的无线电资源和授权频段的无线电资源。然而无线电资源作为一种有限资源，为了满足目前无线通信技术发展的需要，在5G技术中需要考虑各种无线通信***如何在非授权频段共享使用的问题。
在非授权频段的共享使用例如WIFI、基于LTE的LAA技术等。为了使多种技术可以和谐共存，各国监管机构对非授权频段的无线电频谱资源的使用一般采用强制的先听后发技术(Listen Before Talk；LBT)，即只有当侦听到目前信道没有被占用时才能进行数据发送。
那么对于5G新空口设计(NR)技术，在非授权频段的无线电频谱资源上，按照先听后发技术传输上行信息，即当网络设备指示终端设备在指定时刻进行上行反馈时，存在由于信道被其他***占用使得终端设备无法在指定时间向网络设备反馈上行信息，导致网络设备在指定时间不能够接收到终端设备反馈的上行信息。这样网络设备将无法确定终端设备是否正确接收到下行数据，进而不得不重新向终端设备发送下行数据，从而造成***资源的浪费。
发明内容
有鉴于此，本申请实施例提供的一种上行控制信息传输方法及设备，用于解决现有技术中存在的***资源浪费的问题。
本申请实施例提供了一种上行控制信息传输方法，包括：
确定反馈时间，所述反馈时间用于指示终端设备按照所述反馈时间向网络设备发送上行控制信息；

确定反馈时间，所述反馈时间用于指示终端设备按照所述反馈时间向网络设备发送上行控制信息；
将所述反馈时间发送给所述终端设备。
本申请实施例还提供了一种上行控制信息传输设备，包括至少一个处理器及存储器，所述存储器存储有程序，并且被配置成由所述至少一个处理器执行以下步骤：
接收网络设备发送的反馈时间，所述反馈时间用于指示终端设备按照所述反馈时间向网络设备发送上行控制信息；
按照所述反馈时间，将上行控制信息传输给所述网络设备。
本申请至少一个实施例所能够达到的有益效果如下：
本申请实施例通过在网络设备与终端设备之间建立反馈机制，即网络设备确定反馈时间，并将确定的反馈时间发送给终端设备，使终端设备按照该反馈时间向网络设备发送上行控制信息，进而告知网络设备是否已经正确接收到下行数据，有效避免了网络设备因无法确定终端设备是否正确接收到下行数据而不得不重新向终端设备发送下行数据所造成***资源的浪费的问题，同时，终端设备还可以根据网络设备发送的反馈时间灵活实现上行控制信息的反馈，有效增强了NR在非授权频段独立布署时的***鲁棒性。
为了更清楚地说明本申请实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简要介绍，显而易见地，下面描述中的附图仅仅是本申请的一些实施例，对于本领域的普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

基于现有技术中提出的先听后发机制，在实际应用中，这种机制还带来了有些数据不能保证在确定的位置发送的问题。这样的问题使得如果现有的5G技术直接用到非授权频段，性能无法得到保证。尤其是基于5G NR的设计在非授权频段独立布署时，由于反馈信息不能保证在固定时间及时发送，那么在非授权频段的业务比较繁忙的时候，基于NR的***性能将大幅度下降。

下面结合说明书附图对本申请各个实施例作进一步地详细描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
图1为本申请实施例提供的一种上行控制信息传输方法的流程示意图。所述方法可以如下所示。本申请实施例的执行主体可以为基站设备，也可以为网络侧设备，这里不做具体限定。在本申请实施例中统称为网络设备。
步骤101：确定反馈时间，所述反馈时间用于指示终端设备按照所述反馈时间向网络设备发送上行控制信息。
在本申请实施例中，网络设备在向终端设备发送下行控制信息或者下行 数据之前，确定反馈时间，该反馈时间能够指示终端设备向网络设备发送上行控制信息的时机，这样能够有效避免网络设备因无法确定终端设备是否正确接收到下行数据而不得不重新向终端设备发送下行数据所造成***资源的浪费的问题。尤其在非授权频段中传输数据，既能够保证终端设备在确定位置上向网络设备发送例如ACK/NACK这样的上行控制信息，又能够保证在先听后发技术中有多种选择的可能性，进而避免资源被其他设备占用之后导致不能够及时向网络设备反馈上行控制信息的情况。
下面详细说明网络设备如何确定反馈时间。
具体地，网络设备确定当前载波繁忙程度，并根据预设的繁忙程度与反馈时间之间的映射关系，得到与确定的所述当前载波繁忙程度对应的反馈时间。
需要说明的是，本申请实施例中记载的反馈时间可以是指一个时间点，也可以是指一个时间区间，还可以是指多个时间点，这里对其形式不做具体限定。
较优地，所述反馈时间中包含至少一个时间点。
较优地，若所述反馈时间中包含多个时间点，那么所述多个时间点满足时间点连续，或者所述多个时间点满足时间点不连续。
较优地，若所述多个时间点满足时间点不连续，那么所述多个时间点中相邻时间点之间等间隔，或者所述多个时间点中相邻时间点之间不等间隔。
在本申请实施例中，网络设备可以在每一次给终端设备发送下行数据或者下行控制信令之前为其确定反馈时间；也可以在与终端设备建立本次通信连接(这里本次通信连接可以理解为从终端设备接入网络设备到终端设备退出网络设备这一过程，例如：用户打开终端设备的移动数据开关到用户关闭终端设备的移动数据开关)时为其确定反馈时间，之后在本次通信连接周期内终端设备默认按照确定的反馈时间向网络设备发送上行控制信息；还可以网络设备首先为终端设备确定一个反馈时间(可以称之为第一反馈时间)，之 后网络设备在确定载波繁忙程度发送较大变化时，再为其确定一个反馈时间(第二反馈时间)，也就意味着终端设备在接收到第一反馈时间之后，如果之后尚未接收到或者尚未接收到不同的反馈时间，那么都按照第一反馈时间发送上行控制信息。
在本申请实施例中载波繁忙程度的确定方法包括但不限于：
通过以下方式确定当前载波繁忙程度：
其中，U为正整数，表示当前业务与之前业务的相关时间；i为正整数，表示第i次下行数据发送；A
i表示第i次下行数据发送所对应载波的繁忙程度；A
0取值为1；B取值为0或者1。
进一步地，在本申请实施例中，针对第i-1次发送的下行数据，如果终端设备在第一个可选择反馈时间点发送上行控制信息，那么这里B取值为1，否则B取值为0。
下面详细说明网络设备如何确定繁忙程度与反馈时间之间的映射关系。
第一步，将用于传输上行数据的载波对应的时隙划分成不同的时间段，所述时间段中包含至少一个时间点。
第二步，确定不同的所述时间段与繁忙程度之间的映射关系。
其中，繁忙程度越高，对应的时间段中包含的时间点越多且不同的所述时间点之间不连续；反之，繁忙程度越低，对应的时间段中包含的时间点越少。
例如：首先，把[0，1]的区间分为M个连续不重叠的子区间：{[0,a
1)，[a
1,a
2),..,[a
M-1,1]},其中0<a
1<a
2…<a
M-1<1，各个子区间大小可以相同，或者不同。
这里M为正整数。
其次，将得到的子区间进行排序。其中，反馈时间点越少，排序越靠前；对于反馈时间个数相同的，反馈时间点间隔越小，排序越靠前。
第三，将繁忙程度按照从小到大进行排序。即繁忙程度值越小，排序越靠前。
第四，按照排序结构，确定不同子区间与繁忙程度之间的映射关系。
步骤102：将所述反馈时间发送给所述终端设备。
在本申请实施例中，将所述反馈时间携带在下行控制信令中发送给所述终端设备；或者，
通过高层信令将所述反馈时间发送给所述终端设备。
需要说明的是，为了保证网络设备能够将确定的反馈时间发送给终端设备，在本申请实施例中还需要在现有的信令中增加长度为
比特的指示信令，其中
为向上取整。
通过本申请实施例提供的技术方案，确定反馈时间，所述反馈时间用于指示终端设备按照所述反馈时间向网络设备发送上行控制信息；并将所述反馈时间发送给所述终端设备。通过在网络设备与终端设备之间建立反馈机制，即网络设备确定反馈时间，并将确定的反馈时间发送给终端设备，使终端设备按照该反馈时间向网络设备发送上行控制信息，进而告知网络设备是否已经正确接收到下行数据，有效避免了网络设备因无法确定终端设备是否正确接收到下行数据而不得不重新向终端设备发送下行数据所造成***资源的浪费的问题，同时，终端设备还可以根据网络设备发送的反馈时间灵活实现上行控制信息的反馈，有效增强了NR在非授权频段独立布署时的***鲁棒性。
图2为本申请实施例提供的一种上行控制信息传输方法的流程示意图。所述方法可以如下所示。本申请实施例的执行主体为终端设备。
步骤201：接收网络设备发送的反馈时间，所述反馈时间用于指示终端设备按照所述反馈时间向网络设备发送上行控制信息。
步骤202：按照所述反馈时间，将上行控制信息传输给所述网络设备。
在本申请实施例中，繁忙程度与反馈时间之间的映射关系可以由网络设备与终端设备之间通过协商确定，那么终端设备也可以存储该映射关系。当 终端设备在接收到网络设备发送的反馈时间的情况下，如果确定该反馈时间与当前载波的繁忙程度不相适应，那么可以根据该映射关系确定新的反馈时间，并将确定的新的反馈时间通过高层信令或者其他方式通知网络设备。
图3为本申请实施例提供的一种上行控制信息传输设备的结构示意图。所述设备包括：处理单元301和发送单元302，其中：
处理单元301，用于确定反馈时间，所述反馈时间用于指示终端设备按照所述反馈时间向网络设备发送上行控制信息；
发送单元302，用于将所述反馈时间发送给所述终端设备。
在本申请的另一个实施例中，所述处理单元301确定反馈时间，包括：
确定当前载波繁忙程度；
根据预设的繁忙程度与反馈时间之间的映射关系，得到与确定的所述当前载波繁忙程度对应的反馈时间。
在本申请的另一个实施例中，所述处理单元301确定繁忙程度与反馈时间之间的映射关系，包括：
将用于传输上行数据的载波对应的时隙划分成不同的时间段，所述时间段中包含至少一个时间点；
确定不同的所述时间段与繁忙程度之间的映射关系；
其中，繁忙程度越高，对应的时间段中包含的时间点越多且不同的所述时间点之间不连续；反之，繁忙程度越低，对应的时间段中包含的时间点越少。
在本申请的另一个实施例中，所述处理单元301确定当前载波繁忙程度，包括：
通过以下方式确定当前载波繁忙程度：
其中，U为正整数，表示当前业务与之前业务的相关时间；i为正整数，表示第i次下行数据发送；A
i表示第i次下行数据发送所对应载波的繁忙程 度；A
0取值为1；B取值为0或者1。
在本申请的另一个实施例中，所述反馈时间中包含至少一个时间点。
在本申请的另一个实施例中，若所述反馈时间中包含多个时间点，那么所述多个时间点满足时间点连续，或者所述多个时间点满足时间点不连续。

通过高层信令将所述反馈时间发送给所述终端设备。
需要说明的是，本申请实施例提供的设备可以通过软件方式实现，也可以通过硬件方式实现，这里不做具体限定。本申请实施例提供的设备通过在网络设备与终端设备之间建立反馈机制，即网络设备确定反馈时间，并将确定的反馈时间发送给终端设备，使终端设备按照该反馈时间向网络设备发送上行控制信息，进而告知网络设备是否已经正确接收到下行数据，有效避免了网络设备因无法确定终端设备是否正确接收到下行数据而不得不重新向终端设备发送下行数据所造成***资源的浪费的问题，同时，终端设备还可以根据网络设备发送的反馈时间灵活实现上行控制信息的反馈，有效增强了NR在非授权频段独立布署时的***鲁棒性。
