本申请基于申请号为201911252257.5、申请日为2019年12月9日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此以引入方式并入本申请。
技术领域
本申请涉及无线通信领域，具体而言，涉及一种盲检测和解扰方法及装置、存储介质、电子设备。
背景技术
不论是LTE协议还是当前的5G协议，在物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)上发送的下行控制信息(Downlink Control Information，简称DCI)都没有下发任何指示用户设备(User Equipment，简称为UE)接收DCI的具体位置的消息。对UE而言，既不知道是否有属于自己的DCI，也不知道DCI的具体位置，需要在一定规则下进行DCI的盲检测，DCI的检测次数、无线网络临时标识符(RadioNetworkTemporaryIdentifier，简称RNTI)的解扰次数对整个DCI的处理效率和准确率有较大影响。特别是在多用户终端设备中，需要模拟多UE的处理，其DCI盲检次数和RNTI解扰次数会成倍增加。对整个系统的处理能力和处理效率会产生很大影响，也会影响终端的功耗和电池使用时间。
已有方案中，对DCI盲检和RNTI解扰会存在不必要的DCI盲检处理和RNTI解扰处理，增加了误检、漏检DCI的概率，因而对系统的整体处理效率，系统的稳定性产生了不利影响。
针对相关技术中，DCI盲检和RNTI解扰过程中存在误检、漏检等问题，尚未提出有效的技术方案。

在本实施例中提供了一种运行于上述图1所示的终端的盲检测和解扰方法，图2是根据本申请实施例一种盲检测和解扰方法的流程图，如图2所示，该方法包括如下步骤：
步骤S202，根据系统配置的帧结构确定业务类型的被调度时隙或所述业务类型的发送时隙；
步骤S204，确定所述业务类型对应的下行控制信息DCI类型和无线网络临时标识RNTI类型，在所述被调度时隙或所述发送时隙内对所述DCI类型进行相应的物理下行控制信道PDCCH的DCI盲检测，以及在所述被调度时隙或所述发送时隙内对所述RNTI类型进行相应的所述PDCCH的RNTI解扰，以使在除所述被调度时隙或所述发送时隙之外不进行所述DCI盲检测和所述RNTI解扰。
其中，RNTI类型可以包括：小区无线网络临时标识(Cell-RNTI，简称C-RNTI)、随机接入无线网络临时标识符(Random AccesSI-RNTI，简称RA-RNTI)、临时小区无线网络临时标识符(Temporary-C-RNTI，简称T-C-RNTI)、系统消息无线网络临时标识符(System Information-RNTI，简称SI-RNTI)、寻呼消息无线网络临时标识符(Paging-RNTI，简称P-RNTI)、半静态调度小区无线网络标识(Semi-Persistent Scheduling-C-RNTI，简称SPS-C-RNTI)。
通过本申请，根据系统配置的帧结构确定业务类型的被调度时隙或所述业务类型的发送时隙；确定所述业务类型对应的下行控制信息DCI类型和无线网络临时标识RNTI类型，在所述被调度时隙或所述发送时隙内对所述DCI类型进行相应的物理下行控制信道PDCCH的DCI盲检测，以及在所述被调度时隙或所述发送时隙内对所述RNTI类型进行相应的所述PDCCH的RNTI解扰，以使在除所述被调度时隙或所述发送时隙之外不进行所述DCI盲检测和所述 RNTI解扰。采用上述技术方案，解决了相关技术中，DCI盲检和RNTI解扰过程中存在误检、漏检等问题。通过上述技术方案，首先确定业务类型的被调度时隙和发送时隙，然后确定业务类型的DCI类型和RNTI类型，并在调度时隙和发送时隙内对DCI类型进行PDCCH的DCI盲检测，以及对RNTI类型进行PDCCH的RNTI解扰，并且在除了被调度时隙和发送时隙之外，不进行DCI盲检测和RNTI解扰，达到了减少DCI盲检和RNTI解扰过程中存在的误检、漏检的技术效果。
本申请实施例中，对于上述步骤S204，可以通过以下方式实现，根据系统配置的帧结构确定业务类型的被调度时隙或所述业务类型的发送时隙，包括：根据系统配置的帧结构获取所述业务类型所对应的调度间隔或调度周期，其中，所述业务类型包括：上行信道类型、下行信道类型、系统信息、上行信号、下行信号；根据所述调度间隔或所述调度周期，以及所述系统配置的帧结构确定所述业务类型的被调度时隙或所述业务类型的发送时隙。
为了更清楚的说明如何在所述被调度时隙或所述发送时隙内对所述DCI类型进行相应的物理下行控制信道PDCCH的DCI盲检测，以及在所述被调度时隙或所述发送时隙内对所述RNTI类型进行相应的所述PDCCH的RNTI解扰，可通过以下方式实现，在用户设备UE为多个UE的情况下，在所述被调度时隙或所述发送时隙内对所述多个UE中的一个UE进行所述DCI盲检测，以及在所述被调度时隙或发送时隙内对所述多个UE中的一个UE进行所述RNTI解扰。
在一实施例中，对于上述步骤S204可以通过以下方式实现，所述PDCCH的整体带宽包括控制资源集合，在所述被调度时隙或所述发送时隙内对所述DCI类型进行相应的物理下行控制信道PDCCH的DCI盲检测，以及在所述被调度时隙或所述发送时隙内对所述RNTI类型进行相应的所述PDCCH的RNTI解扰，包括：在所述被调度时隙或所述发送时隙内根据调度类型对所述DCI类型进行相应的所述控制资源集合的DCI盲检测，以及在所述被调度时隙或所述发送时隙内对所述RNTI类型进行相应的所述控制资源集合的RNTI解扰，所述调度类型至少包括以下之一：上行动态调整，下行动态调整。
对于上述步骤S204可以通过以下方式实现，所述被调度时隙至少包括以下之一：上行空口时隙、下行空口时隙，在所述被调度时隙或所述发送时隙内对所述DCI类型进行相应的物理下行控制信道PDCCH的DCI盲检测，以及在所 述被调度时隙或所述发送时隙内对所述RNTI类型进行相应的所述PDCCH的RNTI解扰，至少包括以下之一：在所述上行空口时隙或所述发送时隙内根据所述上行动态调整对所述DCI类型进行相应的所述PDCCH的DCI盲检测，以及在所述上行空口时隙或所述发送时隙内根据所述上行动态调整对所述RNTI类型进行相应的所述PDCCH的RNTI解扰；在所述下行空口时隙或所述发送时隙内根据所述下行动态调整对所述DCI类型进行相应的所述PDCCH的DCI盲检测，以及在所述下行空口时隙或所述发送时隙内根据所述下行动态调整对所述RNTI类型进行相应的所述PDCCH的RNTI解扰。
在上述步骤S204之前，上述方法还可以包括以下步骤，所述DCI类型至少包括以下之一：上行DCI、下行DCI，所述被调度时隙还至少包括以下之一：上行调度时隙、下行调度时隙，在所述被调度时隙或所述发送时隙内对所述DCI类型进行相应的物理下行控制信道PDCCH的DCI盲检测，以及在所述被调度时隙或所述发送时隙内对所述RNTI类型进行相应的所述PDCCH的RNTI解扰，所述方法至少包括以下之一：在所述上行调度时隙或所述发送时隙内对所述上行DCI类型进行相应的所述PDCCH的DCI盲检测，以及在所述上行调度时隙或所述发送时隙内对所述RNTI类型进行相应的所述PDCCH的RNTI解扰；在所述下行调度时隙或所述发送时隙内对所述下行DCI类型进行相应的所述PDCCH的DCI盲检测，以及在所述下行调度时隙或所述发送时隙内对所述RNTI类型进行相应的所述PDCCH的RNTI解扰。
需要说明的是，在大带宽、大容量的无线通信场景下，特别是5G增强移动宽带(Enhanced Mobile Broadband，简称EMBB)场景下，DCI盲检测RNTI类型多、且RNTI解扰次数多，会影响DCI的盲检效率和检测的正确性，对于DCI盲检和RNTI解扰，相关技术中会通过减少DCI盲检次数和RNTI解扰次数去提升效率。例如，根据DCI长度，将相同长度的不同类型DCI合并，作为一种DCI类型进行盲检，从而减少盲检次数。通过盲检候选位置推算可能的RNTI取值，将RNTI分组，在检测对应候选位置时采用分组的RNTI解扰。以上方案都只是关注单一时隙中盲检的优化，并没有从整体的系统时序上去考虑将盲检次数和RNTI解扰次数进行优化，会存在不必要的DCI盲检处理和RNTI解扰处理，增加了误检、漏检DCI的概率，对系统的整体处理效率，系统的稳定性都产生不利影响。
为了解决上述问题，以下结合一示例对盲检测和解扰过程进行解释说明，但不用于限定本申请实施例的技术方案，如图3所示，本申请示例的技术方案如下：
步骤S302，根据系统配置的帧结构类型，以及其他系统配置，获取不同业务类型的调度间隔X(单位slot)，或者不同业务类型的调度周期T(单位slot)。上述所说的业务类型可以是具体的上下行信道类型，也可以是各种系统信息，或者上行信号、下行信号，其发送或者接受依赖PDCCH信道中DCI的指示。
步骤S304，根据调度间隔X，或者调度周期T，结合系统配置的帧结构类型，推算出对应业务类型被调度时隙或者发送时隙的slotN(时隙)。
步骤S306，在步骤S304中确定的slot N中，根据业务类型，确定需要检测的DCI类型和需要进行解扰的RNTI类型，进行相应的PDCCH的DCI盲检。在帧结构的其他slot中，不会进行相应DCI检测和RNTI解扰。
需要说明的是，上述步骤可应用于如图4所示的多UE的DCI盲检测和RNTI解扰中，具体如下：
步骤1，对多UE进行PDCCH信道处理。
步骤2，对多UE调度周期和帧结构进行判断。
步骤3，对多UE的RNTI信息进行分组。
步骤4，进行DCI盲检测。
步骤5，进行多UE的RNTI解扰。
步骤6，输出DCI。
综上，采用上述技术方案，只有在调度时隙或者发送时隙才进行相应的PDCCH的DCI盲检和PDCCH的RNTI解扰，而其他时间内不会进行相应DCI检测和RNTI解扰，减少了DCI的盲检次数和RNTI的解扰次数，降低了DCI的误检概率，提高了DCI盲检测的效率，提升了整个系统的性能和稳定性，也降低了终端的功耗。
以下结合一示例对盲检测和解扰过程进行解释说明，但不用于限定本申请实施例的技术方案，本申请示例的技术方案如下：
图5是根据本申请实施例一种帧结构的示意图，如图5所示，标示了SIB 的周期时序，根据5G EMBB协议，将DCI搜索空间分为公共搜索空间(Common Search Space，简称CSS)和UE特定的搜索空间(UE-specific Search Space，简称USS)，这两个搜索空间可以占用不同的频域带宽。
在CSS中，根据帧结构类型，以及不同RNTI类型加扰的DCI调度的信道的周期或时序，对RNTI类型进行归类分组。在符合某一信道(信号)发送周期或者时序的调度时隙上，才会使能DCI盲检测，并使用相应的RNTI类型去解扰处理。
在多用户终端设备中，是基于同一个硬件设备实现多UE与同一基站小区的连接。因此可以认为多UE的通过PDCCH检测到的SIB(SI-RNTI加扰的DCI)信息是相同的，因此在CSS空间进行SIB盲检时，只需要一个UE在满足SFNmod8＝0的无线帧中周期检测即可，不要每个UE都对SIB进行盲检。也可以认为PDCCH盲检DCI时，仅需在SFNmod8＝0的无线帧对应的slot10中使用SI-RNTI去解扰，其他时隙不需要进行SI-RNTI的解扰处理。而对于多用户终端中的其他UE，直接使用已检测到的SIB码流即可，不需要单独进行SIB盲检，从而减少了盲检次数和RNTI解扰次数。其中，RNTI类型可以包括：RA-RNTI、T-C-RNTI、C-RNTI、SI-RNTI、P-RNTI、SPS-C-RNTI。
以下结合一示例对盲检测和解扰过程进行解释说明，但不用于限定本申请实施例的技术方案，本申请示例的技术方案如下：
如图6所示，为随机接入周期时序。在本实施例中，基于此帧结构进行描述。在UE与接入基站小区过程中，MSG2、MSG4等下行信令都需要通过PDCCH检测相应的DCI得到。如图6所示，每个信令下发时刻都有一定的时序关系。UE自身作为发送端，已知MSG1在slot3发送，MSG2会在6个slot之后下发，则UE不需要每个slot对MSG2盲检测，只需在MSG1发送6个slot之后使用RA-RNTI进行DCI的解扰即可。同理，UE已知MSG3的发送时隙，对MSG4的检测会在MSG3发送27个slot后使用T-C-RNTI进行DCI的解扰即可。其他时隙不需要进行RA-RNTI和T-C-RNTI的解扰处理。这样就会减少RNTI的解扰次数，降低误检MSG2、MSG4的概率，提高系统接入的稳定性。
图6中接入时序是5G EMBB图示帧结构下，基站和UE根据处理能力协商的接入时序，其信令调度时序根据帧结构的变化和处理能力的不同会有变化。但都可以根据上述方法来优化RNTI的解扰处理。
在LTE TDD系统中，其帧结构与5G EMBB类似，也可以根据帧结构，以及接入信令调度时序，来使能对应DCI的检测，从而减少盲检次数和RNTI解扰次数。
以下结合一示例对盲检测和解扰过程进行解释说明，但不用于限定本申请实施例的技术方案，本申请示例的技术方案如下：
在5G EMBB等大带宽场景下，会将PDCCH整体带宽划分为不同的(Band Width Part，简称BWP)和控制资源集合CORSET(Control Resource Set)，每个UE会被分配专属的CORSET资源，其专属DCI调度也在CORSET内调度。因此，在多UE终端设备中，首先根据UE所属的BWP ID和CORSET ID，对UE RNTI进行分组，只有在对应CORSET中进行DCI的盲检时才使用该分组中的RNTI值进行解扰处理。在多UE终端设备中，还要根据高层调度，实时动态维护UE的RNTI集合，在某个UE被系统释放(UE实例被删除)，其RNTI值也要从维护的分组中删除，已减少RNTI解扰的次数；如果有新的UE实例加入了系统，要根据所述的CORSET ID，维护到对应的分组中去。
当专属CORSET内盲检物理层DCI时，可以根据调度类型(动态调度或者半静态调度)以及根据帧结构推算，只在某些调度时隙去进行DCI类型的盲检测，并使用相应的RNTI类型去解扰处理。在5G EMBB场景下，协议定义的帧结构基本都是TDD制式，上下行时隙是分时的。
如果是上行动态调度，从调度DCI下发到终端根据调度参数将上行数据从空口发送出去，有固定的调度间隔，一般定义为K2(以slot，时隙为单位)。这样只在提前上行空口时隙K2个slot的时隙才使能上行的DCI盲检，并用RNTI进行解扰，在其他时隙不去盲检查上行DCI，也不会进行RNTI的解扰处理。
如果是下行动态调度，从调度DCI下发到终端根据调度参数接收解析下行数据，也有固定的调度间隔，一般定义为K0(以slot，时隙为单位)。这样只在提前下行空口时隙K0个slot的时隙才使能下行的DCI盲检，并用RNTI进行解扰，在其他时隙不去盲检查下行DCI，也不会进行RNTI的解扰处理。
如果在上述无线系统中对下、下行物理层数据传输是基于半静态调度(SPSI-RNTI类型加扰DCI)，则要根据配置的半静态调度的周期T，在周期T内时，不会有动态调度的DCI，不需要进行上行或者下行DCI的检测和RNTI的解扰，从而也可以减少盲检测次数和RNTI解扰次数，提高了检测效率并降 低了误检DCI的概率。
如图7所示，是5G EMBB上、下行物理层调度时序图。在UE接入基站小区后，上行、下行物理层的数据调度都需要通过PDCCH检测相应的DCI等到。其检测是在USS空间进行。如图7所示，上行调度的间隔K2＝3，K2是有基站配置给UE的(也跟UE的处理能力有关)，也就是说上行slot需要提前3个slot调度DCI。这样UE会根据配置的帧结构，仅在提前上行slot 3个slot的时隙才盲检测上行DCI，其他时隙是不需要对上行DCI进行盲检和RNTI解扰的。同理，附图上中K0＝0(K0也是基站配置给UE的)，如图7中K2、K0的配置是5G EMBB图示帧结构下，基站和UE根据处理能力的一种配置。在帧结构变化和处理能力不同时，上述K2、K0的取值是可变的。
以上仅为一种示例，本实施例在此不作任何限定。
综上，UE需要在每个下行slot都进行下行DCI的盲检和RNTI解扰，但根据帧结构，在上行slot不需要进行DCI的盲检和解扰处理。这样就会减少DCI的盲检次数和RNTI的解扰次数，降低误检上行、下行DCI的概率，提高系统数据处理的稳定性。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本申请各个实施例所述的方法。
