具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
在终端与基站之间进行无线通信的过程中，终端需要在物理下行控制信道(Physical Downlink Control Channel，PDCCH)对基站发送的下行控制信令(Downlink Control Information，DCI)进行检测后，根据该下行控制信令的指示从物理下行共享信道(Physical Downlink Share Channel，PDSCH)接收数据，而该下行控制信令在PDCCH中的检测位置为基站预先配置给该终端的，或者通信协议预定义的。
为了满足业务需求，第五代移动通信技术(the 5th generation mobile communication，5G)系统中引入了对非授权频段(Unlicensed Frequency Bands，UFB)的应用，而在非授权频段上，多个系统(如：Wi-Fi、雷达等系统)需要竞争使用信道资源，基站通过非授权频段向终端发送下行控制信令时，需要使用先听后说(Listen Before Talk，LBT)机制对信道状态进行检测后，当信道状态为空闲状态时占用信道，因此基站无法预知何时能够对信道进行占用，导致通过预先配置控制信令检测位置的方式不适用于非授权频段上。
可选地，基站或其他系统的发送端在非授权频段上对信道的占用时间通过最大信道占用时间(Maximum Channel Occupancy Time，MCOT)进行限制，也即发送端执行一次信道状态检测并成功占用信道后，最大的信道占用时长不能超过MCOT定义的时长，示意性的，请参考图1，发送端持续对信道状态进行检测，并当LBT通过后，在MCOT定义的时长内对信道进行占用；而当LBT失败时，发送端持续对信道状态进行检测，并当LBT通过后，再次在MCOT定义的时长内对信道进行占用。
图2示出了本公开一个示意性实施例提供的通信系统的框图，该通信系统可以包括：核心网21、接入网22和终端23。

接入网22中包括若干个接入网设备220。接入网设备220可以是基站，基站是一种部署在接入网中用以为终端提供无线通信功能的装置。基站可以包括 各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在长期演进(Long Term Evolution，LTE)系统中，称为eNodeB或者eNB；在5G新空口(New Radio，NR)系统中，称为gNode B或者gNB。随着通信技术的演进，“基站”这一名称可能描述，会变化。为方便本申请实施例中，上述为终端提供无线通信功能的装置统称为接入网设备。
终端23可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其他处理设备，以及各种形式的终端(User Equipment，UE)，移动台(Mobile Station，MS)，终端(terminal device)等等。为方便描述，上面提到的设备统称为终端。接入网设备220与终端23之间通过某种空口技术互相通信，例如Uu接口。
可选地，以上述终端23和接入网设备220之间进行无线通信的过程中，可以通过授权频段进行无线通信，也可以通过非授权频段进行无线通信。可选地，本申请实施例中，针对终端23和接入网设备220之间通过非授权频段进行无线通信为例进行说明。
图3示出了本申请一个示例性实施例提供的控制信令的检测方法的流程图，本实施例以该方法应用于图2所示的通信系统中为例进行说明。如图3所示，该方法包括：
步骤301，接入网设备向终端发送下行控制信息，下行控制信息包括信息字段，该信息字段用于指示控制信令在非授权频段中的检测位置；

示意性的，请参考图5，DCI信息500的bitmap中包括28个比特位，每个比特位对应一个symbol，1个slot中包括14个symbol，则前14个比特位对应slot1，后14个比特位对应slot2，每个比特位对应一个取值0或1，当比特位取值为1时表示该比特位对应的symbol需要进行对控制信令的检测，而当比特位取值为0时表示该比特位对应的symbol无需进行对控制信令的检测，如图5所示，该bitmap中每个比特位的取值依次为“1000001000010000000001000000”，则对应至物理下行控制信道的时域单元，需要进行对控制信令的检测的时域单元为slot1的第1个symbol、第7个symbol以及第12个symbol，以及slot2的第8个symbol。
可选地，接入网设备预先定义发送DCI的格式；或，接入网设备预先定义多个发送DCI的格式，并根据MCOT的大小从该多个DCI格式中选择与终端进行无线通信时所应用的DCI，其中，不同格式的DCI包含的信息字段的长度是不同的。可选地，根据MCOT的大小，选择与该MCOT大小适应的DCI。如：MCOT的大小为10个slot，则DCI的长度为包含该10个slot对应的信息字段的长度，如：每个slot中包括14个symbol，每个symbol对应一个比特位，则该DCI的长度可以是包含140bit信息的长度。
可选地，该DCI的信息长度包含该固定长度的bitmap的信息长度，如：DCI包括28bit的bitmap。
可选地，DCI中还包括除bitmap以外的其他字段，如：DCI0中还包括格式0和格式1A区分的标志位、调频标志位等，可选地，该DCI中还包括冗余比特。

可选地，接入网设备对信道的占用受MCOT的限制，DCI中的信息字段的长度根据该MCOT的大小可以对应不同，如：MCOT的大小为10个slot，每个slot中包括14个symbol，而每个symbol在bitmap中对应1bit字符，则DCI中可以包括该140bit的bitmap。可选地，当DCI中信息字段的长度对应的时域大小小于该MCOT的大小时，接入网设备可以发送该DCI以指示一个MCOT内的检测位置，如：DCI中bitmap的长度为28bit，对应28个symbol，也即对应2个slot，而MCOT的大小为10个slot，则接入网设备可以周期性发送5次DCI以指示一个MCOT内的检测位置。示意性的，请参考图6，MCOT的大小为10个slot，若DCI中bitmap的长度为28bit，对应28个symbol，也即对应2个slot，则可以通过发送5次DCI对该检测位置进行指示；若DCI中bitmap的长度为 140bit，对应140个symbol，也即对应10个slot，则接入网设备向终端发送该DCI以指示一个MCOT内的检测位置。
可选地，当DCI中信息字段所对应的时域大小大于MCOT时，则终端可以基于预先定义的规则，或通过接收接入网设备发送的指示信息确定该DCI中的可用信息。如：DCI中信息字段对应的时域为5个slot，而MCOT的长度为2个slot，则预先定义该DCI中信息字段中从高位开始2个slot所对应字段上的指示信息为可用的指示信息。
