进一步的，终端设备工作在空闲态或者连接态下的非连续接收模式时，由于大部分功耗是由于PDCCH监测产生的，对部分PDCCH信号进行接收来监测PDCCH，减少了PDCCH信号的接收数量，应用本方案更能有效的降低功耗。
为了能够更加详尽地了解本申请实施例的特点与技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。
本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统或5G NR系统等。
示例性的，本申请实施例应用的通信系统100可以如图1所示。该通信系统100可以包括网络设备110，网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域内的终端设备120进行通信。可选地，该网络设备110可以是GSM系统或CDMA系统中的网络设备(Base Transceiver Station，BTS)，也可以是WCDMA系统中的网络设备(NodeB，NB)，还可以是LTE系统中的演进型网络设备(Evolutional Node B，eNB或eNodeB)，或者是云无线接入网络(Cloud Radio Access Network，CRAN)中的无线控制器，或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的核心网、基站等网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)中的网络设备等。
该通信系统100还包括位于网络设备110覆盖范围内的至少一个终端设备120。作为在此使用的“终端设备”被设置成通过无线接口通信的终端设备，其可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话；可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System，PCS)终端；可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System，GPS)接收器的个人数字处理(Personal Digital Assistant，PDA)；以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端设备120可以指接入终端、用户设备(User Equipment，UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、PDA、具有无线通信功能的手持设 备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进的PLMN中的终端设备等。
3GPP协议规定，终端设备120通过监测PDCCH来判断网络侧是否有针对自身的调度，然后进一步进行下行和上行的数据传输。
PDCCH的监测过程直接决定了监测PDSCH/PUSCH过程的触发，PDCCH的监测性能是决定无线通信系统寻呼成功率和各种业务性能的重要基础。PDCCH的监测性能一般以漏检概率Pm来衡量，终端侧为保证Pm通常需要设计高性能的PDCCH接收机，以确保各种场景下的PDCCH的接收能力，但过高性能的PDCCH接收机会增加PDCCH的监测功耗。有鉴于此，本申请实施例提供一种PDCCH监测方法，只需要根据接收到对部分PDCCH信号来判断网络侧是否有针对自身的调度，不需要等待全部PDCCH信号均接收到再监测，减少了PDCCH信号的接收数量，即缩短射频通路的工作时间，降低功耗。示例性的，本申请实施例所提供的PDCCH监测方法主要包括如图2所示的以下步骤：
步骤201：在PDCCH信道质量大于预定阈值的情况下，对部分PDCCH信号进行接收。
这里，通过检测PDCCH信道质量判断是否可以对部分PDCCH信号进行接收来判断网络侧是否有针对自身的调度，当PDCCH信道质量越高表示对部分PDCCH信号进行接收时漏检概率越低，当PDCCH信道质量越低表示对部分PDCCH信号进行接收时漏检概率越高。在PDCCH信道质量良好的情况下接收端提前解码PDCCH信号，减少PDCCH信号的接收量。
实际应用中，信道质量可以通过信噪比(Signal Noise Rate，SNR)、信干噪比(Signal to Interference plus Noise Ratio，SINR)、信噪失真比(Signal Noise Distortion Rate，SNR)等指标来表示。
在一种可能的实现方式中，所述对部分PDCCH信号进行接收，包括：获取网络分配的PDCCH信号数目；在网络分配的PDCCH信号数目大于或者等于2的情况下，对第一个PDCCH信号进行接收。
需要说明的是，当网络配置的PDCCH信号数目大于或者等于2的情况下，基于第一个PDCCH信号监测PDCCH才能减少PDCCH信号接收数量。随着5G在网终端设备的增加以及商用网络的业务强度增加，控制信道的负荷会越来越重，PDCCH的容量需要进一步提升，网络配置的PDCCH信号数目也会增加，这种基于第一个PDCCH信号监测PDCCH，能够有效的减少功耗。
在一种可能的实现方式中，所述对部分PDCCH信号进行接收，还包括：在网络分配的PDCCH信号数目大于2的情况下，对前多个PDCCH信号进行接收。
也就是说，当网络分配的PDCCH信号数目为3或更多时，若基于第一个PDCCH信号无法判断网络侧是否有针对自身的调度，还可以接收第二个 PDCCH信号、第三个PDCCH信号来判断，只要根据最后一个PDCCH信号之前的任意一个PDCCH信号确定网络侧没有针对自身的调度，就不用继续接收后续PDCCH信号，整体而言也减少了PDCCH信号的接收数量。
示例性的，PDCCH信号可以为PDCCH时域信号或频域信号。具体地，在NR网络中，PDCCH信号可以为时域OFDM符号。OFDM符号数目可以通过NR RRC协议的控制资源集(CORESET)中的duration字段获得，该字段表征网络配置给终端监测PDCCH的OFDM符号数目。
在一种可能的实现方式中，终端设备工作在空闲态(IDLE)或者连接态下的非连续接收(Connected mode DRX，CDRX)模式，在PDCCH信道质量大于预定阈值的情况下，对部分PDCCH信号进行接收。当终端设备工作在IDLE态或CDRX模式，由于大部分功耗是由于PDCCH监测产生的，对部分PDCCH信号进行接收，更能有效的降低功耗。
具体地，PDCCH信号数目大于1，终端设备工作在空闲态或者连接态下的非连续接收模式，在PDCCH信道质量大于预定阈值的情况下，对部分PDCCH信号进行接收。
在一种可能的实现方式中，所述方法还包括：在PDCCH信道质量小于预定阈值的情况下，对全部PDCCH信号进行接收。也就是说，当PDCCH信道质量越低表示对部分PDCCH信号进行接收时漏检概率越高，终端侧需要对全部PDCCH信号进行接收来监测PDCCH，保证PDCCH解调性能要求。
在一种可能的实现方式中，所述方法还包括：获取第一时间范围内PDCCH的第一漏检概率；所述第一漏检概率小于概率阈值，确定所述PDCCH信道质量大于预定阈值。其中，第一漏检概率用于表征终端设备对PDCCH的实际漏检概率，第一漏检概率作为一种表征PDCCH信道质量的指标，当第一漏检概率小于概率阈值表征PDCCH信道质量较好，接收部分PDCCH信号监测PDCCH能够保证PDCCH解调性能要求。当第一漏检概率大于或者等于概率阈值表征PDCCH信道质量较差，接收部分PDCCH信号监测PDCCH大概率会增加漏检概率，无法保证PDCCH解调性能要求。通过设置这一判断条件，在保证PDCCH解调性能要求的前提下，减少PDCCH信号接收数目，缩短射频通路的工作时间，从而减少调制解调器的功耗。
在一种可能的实现方式中，所述方法还包括：评估对部分PDCCH信号进行接收时PDCCH的第二漏检概率；所述第二漏检概率小于所述概率阈值，确定所述PDCCH信道质量大于预定阈值。其中，第二漏检概率用于表征终端设备基于接收部分PDCCH信号时监测PDCCH时的预估漏检概率，当第二漏检概率小于概率阈值表征接收部分PDCCH信号监测PDCCH能够保证PDCCH解调性能要求。当第二漏检概率大于或者等于概率阈值表征接收部分PDCCH信号监测PDCCH无法保证PDCCH解调性能要求。
实际应用中，可以单独根据第二漏检概率来判断是否接收部分PDCCH信号，或者在第一漏检概率的基础上进一步根据第二漏检概率进行判断，从实际和预估两方面限制，能更好的保证PDCCH解调性能要求，确保基于部分PDCCH信号监测PDCCH的准确性。
在一种可能的实现方式中，所述方法还包括：获取第一时间范围内PDCCH的第一漏检概率；评估对部分PDCCH信号进行接收时PDCCH的第二漏检概率；所述第一漏检概率小于概率阈值，且所述第二漏检概率小于所述概率阈值，确定所述PDCCH信道质量大于预定阈值。
如图3所示，在一种可能的实现方式中，所述评估对部分PDCCH信号进行接收时PDCCH的第二漏检概率，包括：
步骤301：在第二预设时间范围内统计成功解调PDCCH时分配获得的聚合等级组合；
示例性的，聚合等级(Aggregation Level，AL)指示DCI使用的CCE数量，聚合等级组合包括：1、2、4、8、16中的一个或多个。
步骤302：基于聚合等级组合确定对部分PDCCH信号进行接收时PDCCH的目标聚合等级；
步骤303：基于所述目标聚合等级确定对部分PDCCH信号进行接收时PDCCH的目标码率；
这里，目标码率为基于部分PDCCH信号监测PDCCH时码率的目标值，下面以PDCCH信号为OFDM符号为例，对目标码率的确定方法进行进一步的举例。
1、从聚合等级组合确定第一聚合等级；
示例性，取聚合等级组合中聚合度等级的最小值作为第一聚合等级，或者取聚合等级的中间值作为第一聚合度等级，或者根据聚合等级的使用数量，取最多使用数量对应的聚合等级作为第一聚合度等级。
2、基于第一聚合等级确定基于第一个OFDM符号监测PDCCH的第二聚合等级，将第二聚合等级作为目标聚合等级；具体计算公式为：
Figure PCTCN2022141079-appb-000001
其中，AL tar为第二聚合等级，AL rec为第一聚合等级，nrofSym为OFDM符号数目。
3、基于目标聚合等级AL tar确定可用于映射PDCCH的RE数目nrofRE；
4、基于RE数目nrofRE和当前PDCCH监测时的最大下行控制信息(Downlink Control Information，DCI)长度maxDciSize，确定基于第一个OFDM符号监测PDCCH的目标码率r_tar。
具体计算公式为：r_tar＝maxDciSize/nrofRE。
步骤304：基于码率和漏检概率的映射关系，将所述目标码率对应的漏检概率作为所述第二漏检概率。
这里，第二漏检概率用于表征终端设备基于接收PDCCH部分信号时监测PDCCH时的预估漏检概率，第二漏检概率还可以理解为评估PDCCH信道质量解调目标码率时的漏检概率，当第二漏检概率小于概率阈值表征接收部分PDCCH信号监测PDCCH能够保证PDCCH解调性能要求。当第二漏检概率大于或者等于概率阈值表征接收部分PDCCH信号监测PDCCH无法保证PDCCH解调性能要求。
实际应用中，终端设备大多数时间处于低移动性，无线信道条件稳定的环境下。在此环境下有足够时间评估第二漏检概率，使该方法具备较高可靠性。
在一种可能的实现方式中，所述对部分PDCCH信号进行接收，包括：接收到所述第一个PDCCH信号时，对所述第一个PDCCH信号进行校验；所述第一个PDCCH信号校验失败时，停止对所述第一个PDCCH信号之后的PDCCH信号进行接收；所述第一个PDCCH信号校验成功时，继续对所述第一个PDCCH信号之后的PDCCH信号进行接收，直到接收到的PDCCH信号校验失败。
示例性的，通过关闭射频通路停止接收后续PDCCH信号。
在一种可能的实现方式中，该方法还包括：全部PDCCH信号校验成功时，接收物理下行共享信道PDSCH。
示例性的，在NR网络中当PDCCH信号为OFDM符号时，对所述第一个OFDM符号进行校验，包括：对第一个OFDM符号进行循环冗余校验(Cyclic Redundancy Check，CRC)校验，得到CRC校验结果。
示例性的，图4为本申请实施例中PDCCH监测方案的对比示意图，如图4所示，当OFDM符号数目为2时，包括Sym#1和Sym#2，Rx RF On表示射频通路(Radio Frequency，RF)的开启时间，Rx RF Off表示射频通路的关闭时间。
方案1(即现有PDCCH监测方法)终端设备需要接收到两个OFDM符号后才进行CRC校验，根据校验结果确定是否存在需要终端接收的PDSCH，当CRC校验失败时，判断此次没有终端需要接收的PDSCH，结束PDCCH监测。CRC校验成功时，判断此次有终端需要接收的PDSCH。
方案2(即本申请PDCCH监测方法)终端设备需要接收到第一个OFDM符号后进行CRC校验，根据校验结果确定是否存在需要终端接收的PDSCH，当第一个OFDM符号CRC校验失败时，判断此次没有终端需要接收的PDSCH，结束PDCCH监测。当第一个OFDM符号CRC校验成功时，判断此次可能有终端需要接收的PDSCH，继续接收第二个OFDM符号，当第二个OFDM符号CRC校验失败时，判断此次没有终端需要接收的PDSCH，当第二个OFDM符号CRC校验成功时，判断此次有终端需要接收的PDSCH。
比较方案1和方案2可以看出，当没有终端需要接收的PDSCH，只监测第一OFDM符号不需要等待所有符号均接收到再监测PDCCH，减少了 OFDM符号的监测数量，即缩短射频通路的工作时间，降低功耗。而且网络设备配置PDCCH的OFDM符号数越多，降低功耗效果越明显。
在上述实施例的基础上，对PDCCH监测方法进行进一步的举例说明，如图5所示，终端设备应用PDCCH监测方法接收PDSCH时，具体可以包括：
步骤501：获取网络设备为PDCCH配置的OFDM符号数目；
示例性的，获取网络设备配置PDCCH的OFDM符号数目。所述OFDM符号数目可以通过控制资源集(CORESET)中的duration字段获得，该字段表征网络配置给终端监测PDCCH的OFDM符号数目。
示例性的，OFDM符号数目为1、2或3。
步骤502：判断所述OFDM符号数目是否大于1；如果是，执行步骤503；如果否，执行步骤510；
步骤503：获取在预设时间范围内所述PDCCH的第一漏检概率Pm1；
示例性的，终端设备在预设时间范围内，通过监测网络设备给出的特定PDCCH(比如IDLE态的情况下，监测到终端设备的IMSI加扰的寻呼)，通过判断终端设备与网络设备的异常交互，监测下行调度的指示(比如DCI中异常的调度RV和DAI)，可以推断出是否有PDCCH漏检，统计漏检次数进一步推断漏检概率。
步骤504：判断第一漏检概率Pm1是否小于概率阈值Pm_tar；如果是，执行步骤505；如果否，执行步骤510；
步骤505：评估基于第一个OFDM符号监测所述PDCCH的第二漏检概率Pm2；
这里，还可以是评估基于前多个OFDM符号监测所述PDCCH的第二漏检概率Pm2。
步骤506：判断第二漏检概率Pm2是否小于概率阈值Pm_tar；如果是，执行步骤507；如果否，执行步骤510；
步骤507：基于所述PDCCH的第一个OFDM符号监测所述PDCCH；
步骤508：接收到第一个OFDM符号时，对第一个OFDM符号进行校验；校验成功时，执行步骤511；校验失败时，执行步骤509；
步骤509：停止PDCCH监测，关闭射频通路停止接收后续OFDM符号；
步骤510：基于全部OFDM符号监测PDCCH；
步骤511：接收全部OFDM符号，进行校验；校验成功时，执行步骤512；校验失败时，执行步骤509；
步骤512：接收PDSCH。
需要说明的是，图5可以理解为当OFDM符号数目为2时的一种PDCCH的监测方法，当OFDM符号数目为3时，步骤508中当第一个OFDM符号校验成功，接收第二个OFDM符号，第二个OFDM符号校验失败同样 执行步骤509；当第二个OFDM符号校验成功接收第三个OFDM符号，第三个OFDM符号校验失败同样执行步骤509，第三个OFDM符号校验成功执行步骤512。
需要说明的是，终端设备也可以应用PDCCH监测方法上传PUSCH。
采用上述技术方案，通过将第一漏检概率和第二漏检概率与概率阈值进行比较，可以监控PDCCH解调性能，在保证PDCCH解调性能基础上，根据接收到第一个OFDM符号监测PDCCH，不需要等待所有符号均接收到再监测PDCCH，减少了OFDM符号的监测数量，即缩短射频通路的工作时间，降低功耗。而且网络设备配置PDCCH的OFDM符号数越多，应用本方案时降低功耗效果越明显。
为实现本申请实施例的方法，本申请实施例还提供了一种装置，该PDCCH监测装置可以是终端设备120，也可以是应用于终端设备120的芯片，该PDCCH监测装置还可以是网络设备110，也可以是应用于网络设备110的芯片。在本申请中，PDCCH监测装置可以通过或软件、或硬件、或软件与硬件相结合的方式，实现多个单元的功能，使该装置可以执行如上述第一方面中任一项所提供的PDCCH监测方法。第二方面中各技术方案的效果可以参考第一方面中相应的技术方案，本申请对此不再一一赘述。
示例性的，如图6所示，该装置包括：通信单元601和处理单元602。应理解，下述装置实施例仅仅是示意性的，例如，通信单元601和处理单元602的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如通信单元601和处理单元602可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
所述作为分离部件说明的通信单元601和处理单元602可以是或者也可以不是物理上分开的，作为单元显示的通信单元601和处理单元602是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本实施例方案的目的。
另外，在本申请各个实施例中通信单元601和处理单元602可以集成在一个处理器中，也可以是单独物理存在。
通信单元601配置为：在PDCCH信道质量大于预定阈值的情况下，对部分PDCCH信号进行接收。
这样，当网络分配两个以上PDCCH信号时，只需要接收部分PDCCH信号便可实现PDCCH监测，不需要等待全部PDCCH信号均接收到再监测，减少了PDCCH信号的接收数量，即缩短射频通路的工作时间，降低功耗。而且网络分配的PDCCH信号越多，应用本方案时降低功耗效果越明显。
在一种可能的实现方式中，通信单元601配置为：在PDCCH信道质量 小于预定阈值的情况下，对全部PDCCH信号进行接收。
在一种可能的实现方式中，通信单元601配置为：终端设备工作在空闲态或者连接态下的非连续接收模式，在PDCCH信道质量大于预定阈值的情况下，对部分PDCCH信号进行接收。这样，终端设备工作在空闲态或者连接态下的非连续接收模式时，由于大部分功耗是由于PDCCH监测产生的，对部分PDCCH信号进行接收来监测PDCCH，减少了PDCCH信号的接收数量，应用本方案更能有效的降低功耗。
在一种可能的实现方式中，通信单元601配置为：获取网络分配的PDCCH信号数目；在网络分配的PDCCH信号数目大于或者等于2的情况下，对第一个PDCCH信号进行接收。
在一种可能的实现方式中，通信单元601配置为：在网络分配的PDCCH信号数目大于2的情况下，对前多个PDCCH信号进行接收。
在一种可能的实现方式中，处理单元602配置为：接收到所述第一个PDCCH信号时，对所述第一个PDCCH信号进行校验；通信单元601配置为：所述第一个PDCCH信号校验失败时，停止对所述第一个PDCCH信号之后的PDCCH信号进行接收；所述第一个PDCCH信号校验成功时，继续对所述第一个PDCCH信号之后的PDCCH信号进行接收，直到接收到的PDCCH信号校验失败。
在一种可能的实现方式中，通信单元601配置为：全部PDCCH信号校验成功时，接收物理下行共享信道PDSCH。
在一种可能的实现方式中，处理单元602配置为：获取第一时间范围内PDCCH的第一漏检概率；所述第一漏检概率小于概率阈值，确定所述PDCCH信道质量大于预定阈值。其中，第一漏检概率用于表征终端设备对PDCCH的实际漏检概率，通过监控实际漏检概率，将实时漏检概率控制在概率阈值以下，保证接收PDCCH部分信号时PDCCH解调性能要求。
在一种可能的实现方式中，处理单元602配置为：评估对部分PDCCH信号进行接收时PDCCH的第二漏检概率；所述第二漏检概率小于所述概率阈值，确定所述PDCCH信道质量大于预定阈值。其中，第二漏检概率用于表征终端设备基于接收PDCCH部分信号时监测PDCCH时的预估漏检概率，当第二漏检概率小于概率阈值表征接收部分PDCCH信号监测PDCCH能够保证PDCCH解调性能要求。当第二漏检概率大于或者等于概率阈值表征接收部分PDCCH信号监测PDCCH无法保证PDCCH解调性能要求。从实际和预估两方面限制，能更好的保证PDCCH解调性能要求，确保基于第一个OFDM符号监测PDCCH的准确性。
在一种可能的实现方式中，处理单元602配置为：在第二预设时间范围内统计成功解调PDCCH时分配获得的聚合等级组合；基于聚合等级组合 确定对部分PDCCH信号进行接收时PDCCH的目标聚合等级；基于所述目标聚合等级确定对部分PDCCH信号进行接收时PDCCH的目标码率；基于码率和漏检概率的映射关系，将所述目标码率对应的漏检概率作为所述第二漏检概率。
