本申请附加的方面和优点将在下面的描述中部分给出，部分将从下面的描述中变得明显，或通过本申请的实践了解到。
附图说明
本申请上述的和/或附加的方面和优点从下面结合附图对实施例的描述中将变得明显和容易理解，其中：
图1是根据本申请一个实施例的提前终止方法的流程示意图；
图2是根据本申请一个实施例的DCI的码流示意图；

图6是根据本申请一个实施例的通信设备的结构框图。
具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
相关技术中，通过增强覆盖率来提高网速，针对需要进行覆盖增强的Redcap终端设备来说，由于测量不准确或者信道波动等因素，网络可能会为终端设备配置过多的重复发送次数。在网络侧，有可能在终端设备还未发送完所有的重复传输时就已经成功地解调出了数据。那么此时网络可以给终端设备发送一个接收确认指示，指示终端设备停止当前的重复发送。这样的操作有利于终端设备节能。
在之前的5G中的新空口(Newradio，NR)的非授权频谱中，提前终止是支持的。其提前终止的确认是通过下行控制信息(Downlink Control Information,DCI)中的一种下行链路控制信息(Downlinkcontrolinformation，DCI)来指示的。但是针对正常的进行覆盖增强的终端设备等，缺乏提前终止的指示方案。
本申请的实施例中，对DCI中的信息域进行重构，使正常NR终端设备与Redcap终端设备在覆盖增强的场景中能支持提前终止。
为了描述的方便，下面分别集中在网络侧和第一类终端设备侧进行描述，其中，网络侧可以包括基站等网络设备，第一类终端设备可以包括具有终止重传功能的终端设备，比如手机、笔记本电脑以及可穿戴式设备等。
图1是根据本申请实施例提供的一种方法的流程图，该方法应用在基站等网络侧，其中，方法包括：
步骤101，通过下行控制信息DCI中的信息域指示第一类终端设备终止重复传输。
其中，DCI可以理解为PDCCH信道传输的与物理上下行共享信道相关的控制信息，这些DCI信息包含了诸如RB资源分配信息、调制方式MCS、HARQ-ID等等若干相关内容。终端设备只有正确的解码到了DCI信息，才能正确的处理物理下行共享信道(Physical Downlink Shared Channe，PDSCH)数据或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)数据。
在本实施例中，通过下行控制信息DCI中的信息域指示第一类终端设备终止重复传输，其中，参照图2，DCI码流是以比特(bit)为基本单位进行传输(图中的a0、a1…)，因此，这里的信息域可以理解为一个或多个比特位。
综上，本申请实施例的提前终止方法，网络侧通过下行控制信息DCI中的信息域指示第一类终端设备终止重复传输，由此，实现了第一类终端设备在覆盖增强的场景中能支持提前终止，使得第一类终端设备可以在重传场景中节能。

在本实施例中，还可以利用第一信息域的全部或部分比特位信息表征的部分状态指示第一类终端设备终止重复传输。其中，全部比特位信息或部分表征的状态可以理解为全部或部分比特位对应的二进制数组成的状态，比如，当全部比特位为2位时，对应的全部状态为“00”、“01”、“10”、“11”，第一信息域可以对应于其中的全部或者部分状态；又比如，当全部比特位为3位时，对应的状态为“000”、“010”、“001”、“011”、“100”、“111”、“101”、“110”，第一信息域可以对应于其中的全部或者部分状态。

在本示例中，网络侧通过DCI中的第三信息域指示第一类终端设备终止重复传输。
在本实施例中，可以利用第三信息域的全部或部分比特位信息指示第一类终端设备终止重复传输。这里的比特位信息对应的比特位可以是一个或者是多个，当比特位多个时，多个比特位可以是连续的，也可以不是连续的。其中，当比特位为一个或者多个时，可以为第三信息域中的任意一个或多个比特位。即在本示例中，通过第三信息域的一个多或多个比特位的信息指示第一类终端设备的禁止重复传输。
在本实施例中，还可以利用第三信息域的全部或部分比特位信息表征的部分状态指示第一类终端设备终止重复传输。其中，全部比特位信息或部分表征的状态可以理解为全部或部分比特位对应的二进制数组成的状态，比如，当全部比特位为2位时，对应的全部状态为“00”、“01”、“10”、“11”，第三信息域可以对应于其中的全部或者部分状态；又比如，当全部比特位为3位时，对应的状态为“000”、“010”、“001”、“011”、“100”、“111”、“101”、“110”，第三信息域可以对应于其中的全部或者部分状态。
需要说明的是，上述第一信息域到第三信息域可以为DCI中任意三个不同的信息域，需要说明的是，信息域可以是DCI中的未被定义的空闲的比特位组成的，也可以是复用其他信息域得到的，当第一信息域到第三信息域是复用其他信息域时，对应的第一信息域到第三信息域均可以为以下的一种：
(1)指示第二类终端设备的功率控制的功率控制域TPC。
可以理解，在本示例中，对应的信息域用于指示第二类终端设备的功率控制，其中，第二类终端设备可以理解为与第一类终端设备的终端设备能力或信道状态不同的终端设备。例如第一类终端设备是正常的NR终端，第二类终端设备是Redcap终端。或者第一类终端设备是覆盖较差，需要使用重复传输 的终端，第二类终端设备是覆盖较好，不需要使用重复传输的终端设备。
在本示例中，当第一类终端设备被配置使用重复传输时，那么此时DCI中的TPC信息域将不会再用作功率控制。此时可以利用TPC信息域中的部分bit或者部分状态来进行提前终止的指示。例如，利用TPC中的1bit来进行指示，或者，将TPC两bit的信息设置为00时表示提前终止。
当然，在本示例中，信息域剩余的比特信息还可以用于执行对应的功率控制功能。
举例而言，当第一信息域还用于指示第二类终端设备的功率控制时，则网络侧可以响应于利用第一信息域的部分比特位信息指示第一类终端设备终止重复传输，或者，利用第一信息域的全部或部分比特位信息表征的部分状态指示第一类终端设备终止重复传输，则可以利用第一信息域的剩余比特位或剩余状态指示第一类终端设备的功率控制，比如剩余的比特位为第2位比特，则可以使用第2位比特位为0或者1时来指示第一类终端设备的功率控制。
(2)用于指示第二类终端设备的调制与编码策略的调制与编码策略信息域(Modulation and Coding Scheme，MCS)。
可以理解，在本示例中，对应的信息域用于指示第二类终端设备的调制与编码策略的调制与编码策略，其中，第二类终端设备可以理解为与第一类终端设备的终端设备能力或信道状态不同的终端设备。例如第一类终端设备是正常的NR终端，第二类终端设备是Redcap终端。或者第一类终端设备是覆盖较差，需要使用重复传输的终端，第二类终端设备是覆盖较好，不需要使用重复传输的终端设备。
在本示例中，当第一类终端设备被配置使用重复传输时，那么此时几乎不可能使用高阶的MCS，例如64QAM。那么此时可以利用MCS的部分状态和信息来进行提前终止的指示。
例如：MCS共有5个bit，那么当第一类终端设备被配置使用重复传输时，那么此时只有4个bit用来指示MCS，剩余1个bit用来指示是否提前终止。或者，MCS共有5个bit，一共可以表征32个状态，那么此时可以使用前31种状态来进行MCS的指示或者其他指示，最后一个状态11111来指示提前终止。
当然，在本示例中，信息域剩余的比特信息还可以用于执行对应的调制与编码策略功能。
举例而言，当第二信息域还用于指示调制与编码策略，则网络侧可以响应于利用第二信息域的部分比特位信息指示第一类终端设备终止重复传输，或者，利用第二信息域的全部或部分比特位信息表征的部分状态指示第一类终端设备终止重复传输，利用第二信息域的剩余比特位或剩余状态指示第一类终端设备的调制与编码策略，比如剩余的比特位为第2位比特，则可以使用第2位比特位为0或者1时来指示第一类终端设备的调制与编码策略。
(3)用于指示第二类终端设备的混合自动请求重传进程标识，即为混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)进程标识HARQ process ID对应的信息域。
可以理解，在本示例中，对应的信息域用于指示第二类终端设备的调制与编码策略的调制与编码策略，其中，第二类终端设备可以理解为与第一类终端设备的终端设备能力或信道状态不同的终端设备。例如第一类终端设备是正常的NR终端，第二类终端设备是Redcap终端。或者第一类终端设备是覆盖较差，需要使用重复传输的终端，第二类终端设备是覆盖较好，不需要使用重复传输的终端设备。
在本示例中，当第一类终端设备被配置使用重复传输时，那么此时几乎不可能使用16个并行的HARQ传输。那么此时可以利用HARQ process ID的部分状态或比特来进行提前终止的指示。
例如：HARQ process ID共有4个bit，那么当终端设备被配置使用重复传输时，那么此时只有3个bit用来指示HARQ process ID，剩余1个bit用来指示是否提前终止。或者，HARQ process ID共有4个bit，一共可以表征16个状态，那么此时可以使用前15种状态来进行HARQ process ID的指示或者其他指示，最后一个状态1111来指示提前终止。
当然，在本示例中，信息域剩余的比特信息还可以用于执行对应的调制与编码策略功能。
举例而言，当第三信息域还用于指示混合自动请求重传进程标识，则网络侧可以响应于利用第三信息域的部分比特位信息指示第一类终端设备终止重复传输，或者，利用第三信息域的全部或部分比特位信息表征的部分状态指示第一类终端设备终止重复传输，利用第三信息域的剩余比特位或剩余状态指示第一类终端设备的混合自动请求重传进程标识，比如，剩余的比特位为第2位比特，则可以使用第2 位比特位为0或者1时来指示第一类终端设备的混合自动请求重传进程标识。
综上，本申请实施例的提前终止方法，可以根据场景需要采用不同的方式确定下行控制信息DCI中的信息域，提高了提前终止的实用性。
下面其次集中在第一终端设备侧描述本申请实施例的提前终止方法。
图3是根据本申请另一个实施例的提前终止方法的流程图，如图3所示，该方法包括：
步骤301，监测携带下行控制信息DCI的物理下行控制信道PDCCH。
步骤302，根据DCI信息域的指示信息，终止第一类终端设备进行重复传输。
其中，DCI可以理解为PDCCH信道传输的与物理上下行共享信道相关的控制信息，这些DCI信息包含了诸如RB资源分配信息、调制方式MCS、HARQ-ID等等若干相关内容。终端设备只有正确的解码到了DCI信息，才能正确的处理物理下行共享信道(Physical Downlink Shared Channe，PDSCH)数据或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)数据。
在本实施例中，通过下行控制信息DCI中的信息域指示第一类终端设备终止重复传输，从而，在本示例中，监测携带下行控制信息DCI的PDCCH，进而，根据DCI信息域的指示信息，终止第一类终端设备进行重复传输。
综上，本申请实施例的提前终止方法，第一类终端设备监测携带下行控制信息DCI的PDCCH，进而，根据DCI信息域的指示信息，终止第一类终端设备进行重复传输。由此，实现了第一类终端设备在覆盖增强的场景中能支持提前终止，使得第一类终端设备可以在重传场景中节能。
