技术领域
本公开涉及通信技术领域，尤其涉及一种控制信道检测方法、装置、终端、基站及存储介质。
背景技术
随着无线通信的发展，用户对移动通信的需求越来越高。尤其是在通信带宽和通信速率上，为满足用户对通信高速率的要求，需要开发更大带宽的频谱。
目前，3GPP标准开始研究在52.6GHz—71GHz的频段上进行移动无线通信，更高的通信频率虽然能够带来更大的带宽优势，但对无线通信设计却带来更大的挑战，主要是：更高的频率有更大的多普勒频偏，同时也有更大的相位噪声产生。为解决高频带来的多普勒和相位噪声的影响，采用更高的SCS(Sub-Carrier Spacing，子载波间隔)。
基站和终端数据通信之前，需要基站发送调度信令给终端，该调度信令在PDCCH(Physical Downlink Control Channel，物理下行控制信道)上发送,考虑到一个基站会服务多个终端,同时下行信道质量是变换的，为了让基站调度具有灵活性，现有协议规定，终端在每个时隙里，需要检测多个候选PDCCH信道。如果让终端检测的候选PDCCH信道越多，基站调度也就越灵活，同时要求终端检测信道的能力越强，这就引起基站调度的灵活性和终端检测能力平衡的问题。
但是，随着SCS的增大，时隙时长变小，在对应的时隙内将导致终端无法完成控制信令的接收和配置过程。

为了便于清楚描述本公开实施例的技术方案，在本公开的各实施例中，若采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分，本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定。
随着无线通信的发展，用户对移动通信的需求越来越高。尤其是在通信带宽和通信速率上，为满足用户对通信高速率的要求，需要开发更大带宽的频谱。
目前，3GPP标准开始研究在52.6GHz—71GHz的频段上进行移动无线通信，更高的通信频率虽然能够带来更大的带宽优势，但对无线通信设计却带来更大的挑战，主要是：更高的频率有更大的多普勒频偏，同时也有更大的相位噪声产生。为解决高频带来的多普勒和相位噪声的影响，采用更高的SCS(sub-carrier spacing,子载波间隔)。
基站和终端数据通信之前，需要基站发送调度信令给终端，该调度信令在PDCCH(Physical Downlink Control Channel，物理下行控制信道)上发送,考虑到一个基站会服务多个终端,同时下行信道质量是变换的，为了让基站调度具有灵活性，现有协议规定，终端在每个时隙里，需要检测多个候选PDCCH信道。如果让终端检测的候选PDCCH信道越多，基站调度也就越灵活，同时要求终端检测信道的能力越强，这就引起基站调度的灵活性和终端检测能力平衡的问题。
但是，当前标准定义了SCS在120KHz以下的每个时隙终端检测PDCCH候选信道的数量。对于SCS大于120KHz情况下，如何定义终端检测PDCCH候选信道数量的能力，目前还没有更好的优化方案。
其中，(1)针对候选PDCCH信道：
PDCCH信道是用来发送DCI(Downlink Control Information,下行控制信息)，其传输的信息包括公共控制信息和用户专属控制信息。
为了便于描述PDCCH，NR(New Radio，新空口)中引入了CORESET(control resource set，控制资源集合)概念。其中，该CORESET用于表征PDCCH信道资源块的大小。一个CORESET由若干个CCE(Control-Channel  Element，控制信道单元)组成，每6个CCE构成一个REG(Resource Element Group，资源单元组)，每个REG包含一个RB(Resource Block，资源块)。
在一个CORESET中，包括多个候选PDCCH，这些候选的控制信道需要终端都进行检测。一般来讲，任何一个或者多个CCE都可以形成一个候选PDCCH。标准当前规定，PDCCH由1个CCE组成的，叫做CCE聚合等级为1的候选PDCCH，PDCCH由2个CCE组成的，叫做CCE聚合等级为2的候选PDCCH，PDCCH由4个CCE组成的，叫做CCE聚合等级为4的候选PDCCH，以此类推，当前标准协议规定支持的CCE聚合等级为：1、2、4、8、16。
在一个CORESET中，相同CCE聚合级别的候选PDCCH也会有多个，当前标准协议规定的数量为0、1、2、3、4、5、6、8。
比如：广播信道的候选PDCCH数量和CCE的聚合等级，如表1所示。
表1
CCE聚合等级 候选PDCCH数量
4 4
8 2
16 1
其中，用于调度传输广播信道的控制信道，CCE聚合级别为4的，有4个候选PDCCH；CCE聚合级别为8的，有2个候选PDCCH；CCE聚合级别为16的，有1个候选PDCCH；即总共有4+2+1＝7个候选PDCCH需要终端进行检测。
(2)搜索空间(search space)类型：
搜索空间定义的是终端需要进行PDCCH检测的时间范围。搜索空间分为CSS(Common Search Space，公共搜索空间)和USS((User Equipment specific search space，终端专属搜索空间)。其中，CSS是指所有终端或者一组终端需要进行PDCCH检测的搜索空间；USS是基站单位为某一终端单独配置，只需要被配置的终端进行PDCCH检测的搜索空间。
对于CSS需要检测的候选控制信道的第一数量记为：
Figure PCTCN2021081600-appb-000001
对于USS， 需要检测的候选控制信道的第二数量记为
Figure PCTCN2021081600-appb-000002
在每个时隙中，检测候选PDCCH的总数量
Figure PCTCN2021081600-appb-000003
为第一数量和第二数量之和、且不超过一定的门限值，当前标准协议确定的检测能力，如表2所示。
表2
Figure PCTCN2021081600-appb-000004
其中，μ是计算SCS的因子或者索引数值，即SCS＝2 μ×15KHz。比如：μ为0，则SCS为15KHz，即对于SCS为15KHz的时隙，其检测最大候选PDCCH数量为44。
同样，对于CSS，需要满足上述候选检测信道的数量所需要的第一CCE数量记为：
Figure PCTCN2021081600-appb-000005
对于USS，需要满足上述候选检测信道的数目所需要的第二CCE数量记为
Figure PCTCN2021081600-appb-000006
在每个时隙中，CCE的总数量
Figure PCTCN2021081600-appb-000007
为第一CCE数量和第二CCE数量之和、且不超过一定的门限，当前标准协议确定的检测能力，如表3所示。
表3
Figure PCTCN2021081600-appb-000008
因此，当前NR协议中定义的候选PDCCH检测信道数量和CCE数量，都是基于时隙为单位的，也就是说，在终端，需要以时隙为单位，进行PDCCH盲检，终端根据检测出来的DCI内容，进行PDSCH(Physical Downlink Shared Channel，物理下行共享信道)数据的接收或者PUSCH(Physical Uplink Share Channel，物理层上行共享信道)发送。
比如：当基站调度终端接收一个PDSCH时，基站先在PDCCH上发送一个调度信息或者DCI，DCI指示PDSCH的时域/频域信息，调制编码速率以及其它信息。终端在约定的时隙位置进行PDCCH的检测(约定的时间是由基站配置的)，并解析DCI内容，根据解析的DCI内容，配置PDSCH的接收参数，PDSCH解调&译码模块根据配置信息进行PDSCH的解调和译码。
其中，PDCCH接收与检测模块，花费时间为t1；PDCCH接收与检测模块将检测出来的DCI信息发送给DCI解析模块，花费时间为t2；DCI解析模块，花费时间为t3；DCI解析模块将PDSCH配置信息发送给PDSCH解调&译码模块，花费时间为t4；PDSCH解调&译码模块，花费时间为t5。
当SCS比较小时，比如，小于等于120KHz时，时隙长度大于等于0.125ms，当每个时隙都有DCI调度信息时，在0.125ms内，能够完成PDCCH的检测、DCI解析和PDSCH调度信息的配置过程。但随着SCS的增大，时隙变小，在对应的时隙内，由于如下原因，导致终端难于完成控制信令接收和配置过程：
1:虽然随着SCS的增大，搜索复杂度的配置可能进一步减少(比如：候选PDCCH数量，CCE数量)，但每次调度的信息在不同模块之间传输需要的时间无法减少，而且搜索复杂度的减少(如：减少CCE数量，减少候选PDCCH的检测数量)，会减少基站调度的灵活性。
2：虽然可以通过增加控制信道的计算资源来提高并行度，但这会增加终端的实现成本(相对应SCS<＝120KHz的设备)。
因此，采用传统的基于时隙为单位，定义控制信道检测能力的方法已经不能满足无线通信发展的需求。
针对上述问题，本公开实施例提供一种控制信道检测方法、装置、终端、基站及存储介质，以满足无线通信发展的需求。
本公开实施例提供的控制信道检测方法、装置、终端、基站及存储介质可以应用在无线通信系统或无线与有线结合的系统。包括但不限于5G系统(如NR系统)、6G系统、卫星系统、车联网系统、演进型长期演进(Long Term Evolution，LTE)系统，上述系统的后续演进通信系统等。
本公开实施例提供的基站可以包含但不限于以下中的一种或多种：通常所用的基站、演进型基站(evolved node base station，eNB)、5G系统中的网络侧设备(例如下一代基站(next generation node base station，gNB)、发送和接收点(transmission and reception point，TRP))等设备。
本公开实施例提供的终端有可以被称为用户设备(UserEquipment，简称为UE)等。终端包括单不限于手持设备、车载设备。例如，可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本或者个人数字助理(Personal Digital Assistant，PDA)等。
下面通过具体实施例进行说明。
图1为本公开实施例提供的一种控制信道检测方法的流程图，该控制信道检测方法可以用于终端。如图1所示，该控制信道检测方法可以包括如下步骤：
步骤110：确定用于控制信道检测的检测时隙组，该检测时隙组用于表征在指定时隙条件时能够共享控制信道检测能力的时隙组。其中，共享控制信道检测能力可以指的是该控制信道检测能力是基于时隙组的，即多个时隙对应一个控制信道检测能力。
具体地，控制信道(control channel)检测可以用于现有的Uu接口；也可以用于边链路中，即直连(side link)链路。
检测时隙组可以指的是多个时隙组成的一个时隙组，并且这些个时隙在指定时隙条件时共享一个控制信道检测能力。
比如：控制信道为PDCCH；用于PDCCH检测的检测时隙组中包括多个时隙，这些个时隙在指定时隙条件时共享一个PDCCH检测能力。
其中，指定时隙条件可以是根据实际情况设置的SCS的一个具体的值或一个取值范围。比如：指定时隙条件为SCS等于120KHz；或指定时隙条件为SCS大于120KHz。
步骤120：确定检测时隙组的搜索空间。
具体地，搜索空间可以指的是检测时隙组中配置了控制信道检测能力的时间范围，其是终端需要进行控制信道检测的时间范围，以及基站需要发送 控制信道的时间范围。另外，终端需要进行控制信道检测的搜索空间和基站需要发送控制信道的搜索空间，二者是相同的，这样可以减少终端的实现复杂度。
其中，搜索空间的类型可以是CSS，也可以是USS。搜索空间的数量可以是一个或多个。
比如：SCS等于480KHz，4时隙组成1个检测时隙组，搜索空间的数量为1个，该搜索空间配置在该检测时隙组的时隙1中，而检测时隙组的其他时隙上不配置搜索空间。
又比如：SCS等于960KHz，8时隙组成1个检测时隙组，搜索空间的数量为2个，分配配置在时隙0和时隙4中。
步骤130：在搜索空间内进行控制信道检测。
具体地，由于基站在控制信道上发送控制信息时，只在检测时隙组中配置了控制信道检测能力的搜索空间内发送控制信息，所以，终端可以只在配置了控制信道检测能力的搜索空间内进行控制信道检测。
比如：基站在PDCCH上发送DCI时，只在检测时隙组中配置了PDCCH检测能力的时隙0上发送DCI，在DCI上，每个DCI可以调度至多4个PDSCH信道数据或者4个PUSCH上行共享信道数据。与此对应的，终端只在时隙组中配置了PDCCH检测能力的时隙0上检测PDCCH，并根据检测到的DCI，进行PDSCH配置接收或者PUSCH发送，当进行PDSCH接收时，同时需要相应的解调和译码。
由上述实施例可见，通过确定用于控制信道检测的检测时隙组，该检测时隙组用于表征在指定时隙条件时能够共享控制信道检测能力的时隙组，确定检测时隙组的搜索空间，以及在搜索空间内进行控制信道检测，从而实现了以检测时隙组为单元进行控制信道检测，避免了随着SCS的增大而导致的终端在对应的时隙内无法完成控制信令的接收和配置过程，还降低了终端进行控制信道检测的复杂度。
进一步地，建立在上述方法的基础上，上述步骤110中的所述指定时隙条件可以包括SCS大于120KHz；所述共享控制信道检测能力用于表征多个 时隙对应的控制信道检测能力。
具体地，由于当前标准只定义了SCS在120KHz以下的每个时隙终端检测PDCCH候选信道的数量，所以对于SCS大于120KHz情况，可以采用以时隙组为单元，即多个时隙对应(或称为共享)一个控制信道检测能力，并进行搜索空间的配置，来实现相应的控制信道检测。
对应或共享控制信道检测能力可以指的是同一时隙中的多个时隙共享一个控制信道检测能力。比如：控制信道为PDCCH；用于PDCCH检测的检测时隙组中包括多个时隙，这些个时隙在指定时隙条件时共享一个PDCCH检测能力。
由上述实施例可见，在SCS大于120KHz时，可以以检测时隙组为单元进行控制信道检测，即多个时隙对应一个控制信道检测能力，从而避免了随着SCS的增大而导致的终端在对应的时隙内无法完成控制信令的接收和配置过程，满足了无线通信发展的需求。
进一步地，建立在上述方法的基础上，在执行步骤110中确定用于控制信道检测的检测时隙组时，可以包括(1-1-1)或(1-1-2)：
(1-1-1)根据第一节点与第二节点之间的接口协议确定针对所述检测时隙组的第一配置信息，并根据所述第一配置信息确定所述检测时隙组。
具体地，第一节点可以是基站，第二节点可以是终端；或者，第一节点可以是终端，第二节点可以是基站。即根据基站和终端之间的接口协议确定针对所述检测时隙组的第一配置信息。
(1-1-2)接收基站发送的所述第一配置信息，并根据所述第一配置信息确定所述检测时隙组。
具体地，基站可以通过高层信令将第一配置信息发送至终端，这样终端可以通过高层信令获取该第一配置信息。
由上述实施例可见，可以根据第一节点与第二节点之间的接口协议确定针对所述检测时隙组的第一配置信息，并根据所述第一配置信息确定所述检测时隙组，也可以接收基站发送的所述第一配置信息，并根据所述第一配置信息确定所述检测时隙组，从而丰富了第一配置信息的获取方式，进而提高 了确定检测时隙组的可靠性。
进一步地，建立在上述方法的基础上，上述(1-1-1)或(1-1-2)中的第一配置信息可以包括：
所述检测时隙组中包含的时隙个数；
所述检测时隙组中最大候选控制信道数量；
所述检测时隙组中最大CCE数量。
其中，时隙个数与SCS相关联，例如若SCS为480KHz时时隙个数为4，SCS为960KHz时时隙个数为8。当然在此仅为举例说明，时隙个数与SCS的关联关系可以基于需求进行设定。
具体地，上述检测时隙组中包含的时隙个数可以是直接配置的，比如：时隙个数为5或4；此外，所述时隙个数可以是基于SCS与预设参考SCS的比值所确定的，此时可以是以某一特定的SCS为参考，进行倍数扩展的。其扩展公式为：
Figure PCTCN2021081600-appb-000009
其中，μ r为参考SCS，k 0是扩展系数。该扩展系数可以为1、2或其他数值。比如：以0.125ms的长度(SCS＝120KHz)为参考(μ r＝3)，进行倍数扩展。又比如：当SCS＝480KHz时，时隙个数为K μ＝5＝1*2 5-3＝4。
最大候选控制信道数量与SCS相关联，例如SCS＝480KHz时最大候选控制信道数量为M2，SCS＝960KHz时最大候选控制信道数量为M3，且M3＞M2。当然在此仅为举例说明，最大候选控制信道数量与SCS的关联关系可以基于需求进行设定。
上述最大候选控制信道数量，若控制信道为PDCCH，该最大候选控制信道数量为最大候选PDCCH数量，可以如表4中的
Figure PCTCN2021081600-appb-000010
其中，配置最大候选PDCCH数量，依赖于终端的能力。
表4
Figure PCTCN2021081600-appb-000011
Figure PCTCN2021081600-appb-000012
其中，μ是计算SCS的因子或者索引数值，即SCS＝2 μ×15KHz。比如：μ为4，则SCS为240KHz。
当SCS为240KHz时，共享时隙为2，最大候选PDCCH数量为M1。当SCS为480KHz时，共享时隙为4，最大候选PDCCH数量为M2。当SCS为960KHz时，共享时隙为8，最大候选PDCCH数量为M3。当SCS为1920KHz时，共享时隙为16，最大候选PDCCH数量为M4。其中，M1/M2/M3/M4均为整数，且M1<＝M2<＝M3<＝M4。比如：M1＝20，M2＝22，M3＝36，M4＝44。
最大CCE数量与SCS相关联，例如SCS＝480KHz时最大CCE数量为C2，SCS＝960KHz时最大CCE数量为C3，且C3≥C2。当然在此仅为举例说明，最大CCE数量与SCS的关联关系可以基于需求进行设定。
上述最大CCE数量，可以如表5中的
Figure PCTCN2021081600-appb-000013
其中，配置最大CCE数量，同样依赖于终端的能力。
表5
Figure PCTCN2021081600-appb-000014
其中，当SCS为240KHz时，共享时隙为2，最大CCE数量为C1。当SCS为480KHz时，共享时隙为4，最大CCE数量为C2。当SCS为960KHz时，共享时隙为8，最大CCE数量为C3。当SCS为1920KHz时，共享时隙为16，最大CCE数量为C4。其中，C1/C2/C3/C4均为整数，且C1<＝C2<＝C3<＝C4。比如：C1＝32，C2＝48，C3＝56，C4＝56。
由上述实施例可见，在确定检测时隙组时，可以根据第一配置信息中的时隙个数、最大候选控制信道数量、最大CCE数量来确定，从而提高了确定检测时隙组的准确性。
与此对应的，在执行步骤130中在搜索空间内进行控制信道检测时，可以包括：
(1-2-1)按照控制信道检测数量不大于所述最大候选控制信道数量，在所述搜索空间内进行控制信道检测。
具体地，基站发送控制信道时，确保在“配置的最大候选控制信道数量”范围之内；与此对应的，终端在进行控制信道检测时，仅仅在“配置的最大候选控制信道数量”范围之内进行控制信道检测。
比如：最大候选控制信道数量为20，则控制信道检测数量小于或等于20。
由上述实施例可见，按照控制信道检测数量不大于所述最大候选控制信道数量，在所述搜索空间内进行控制信道检测，从而保证了在终端能力范围之内进行控制信道检测，提高了控制信道检测的可靠性。
进一步地，建立在上述方法的基础上，在执行步骤120中确定检测时隙组的搜索空间时，可以包括(1-3-1)或(1-3-2)：
(1-3-1)根据第一节点与第二节点之间的接口协议确定针对所述搜索空间的第二配置信息，并根据所述第二配置信息确定所述搜索空间。
具体地，第一节点可以是基站，第二节点可以是终端；或者，第一节点可以是终端，第二节点可以是基站。即根据基站和终端之间的接口协议确定针对所述搜索空间的第二配置信息。
(1-3-2)接收基站发送的所述第二配置信息，并根据所述第二配置信息确定所述搜索空间。
具体地，基站可以通过高层信令将第二配置信息发送至终端，这样终端可以通过高层信令获取该第二配置信息。
由上述实施例可见，可以根据第一节点与第二节点之间的接口协议确定针对所述搜索空间的第二配置信息，并根据所述第二配置信息确定所述搜索空间，也可以接收基站发送的所述第二配置信息，并根据所述第二配置信息确定所述搜索空间，从而丰富了第二配置信息的获取方式，进而提高了确定搜索空间的可靠性。
进一步地，建立在上述方法的基础上，上述(1-3-1)或(1-3-2)中的第 二配置信息可以包括：
第一指示信息，所述第一指示信息用于指示具有控制信道检测机会的检测时隙组；
第二指示信息，所述第二指示信息用于指示控制信道检测机会位于检测时隙组中的指定位置，所述指定位置包括位于检测时隙组中的一个指定时隙或多个指定时隙。其中，多个指定时隙可以指的是至少两个时隙，比如：检测时隙组中的时隙0和时隙3。
具体地，上述第一指示信息可以指示哪些时隙组中有控制信道的检测机会，当时隙组配置了检测机会，终端在该时隙组中进行控制信道的检测，反之不用在该时隙组中进行控制信道检测。
比如：{0，1，2，3}是一个时隙组，该时隙组具有控制信道检测机会；而{8，9，10，11}是另一个时隙组，该时隙组不具有控制信道检测机会。
其中，在指示具有控制信道检测机会的检测时隙组时，可以使用如下两种配置方式：
方式一，使用位图(bitmap)的方式表示。
比如：使用80bit大小数值，表示10ms的配置(0.125ms为一个时隙组，10ms包含80个时隙组)，1表示对应时隙组需要进行PDCCH检测，0表示对应时隙组不需要进行PDCCH检测。
方式二，使用周期方式指示。其配置参数包括：时隙组周期，和时隙组偏移量。
比如：基站通过高层信令配置了基于时隙组的搜索空间，4个时隙为一组(SCS＝480KHz，每时隙长度是0.125ms/4)。在高层信令配置中，搜索空间周期是4个SG(Slot Group，时隙组),偏移量是2SG。终端在检测PDCCH时，只在周期为4SG，偏移量为2SG的SG上进行PDCCH的检测。
上述控制信道检测机会位于在所述检测时隙组中的位置，可以指的是配置有控制信道检测机会的时隙和符号的位置。
比如：{0，1，2，3}是一个时隙组，该时隙组具有控制信道检测机会位于时隙0中。
可选地，所述第二配置信息可以包括：所述检测时隙组的起始位置偏移(offset)，所述起始位置偏移用于指示所述检测时隙组中包括的各个时隙。
具体地，该起始位置偏移(offset)用于指示一个时隙组是由哪些时隙组成的。
当起始位置偏移(offset)为0,时隙组的时隙个数为4时，在时隙组包括的时隙编号有{4n，4n+1，4n+2，4n+3}。其中，n是大于或等于0的整数。比如：{0，1，2，3}是一个时隙组，{8，9，10，11}是另一个时隙组。
当起始位置偏移(offset)为2,时隙组的时隙个数为4时，在时隙组包括的时隙编号有{4n+2，4n+1+2，4n+2+2，4n+3+2}。其中，n是大于或等于0的整数。比如：{2，3，4，5}是一个时隙组，{10，11，12，13}是另一个时隙组。
基站可以通过高层信令将起始位置偏移(offset)发送至终端。基站发送控制信道时，确保在“配置的搜索空间内”的时间域上发送控制信道。与此对应的，终端只在配置的时间域上进行控制信道检测。
另外，若起始位置偏移(offset)一直为0时，可作为默认设置，不进行指示。
与此对应的，在执行步骤130中在搜索空间内进行控制信道检测时，可以包括：
(1-4-1)在所述检测时隙组中的一个指定时隙或多个指定时隙上，进行控制信道检测。
具体地，该控制信道检测机会位于在所述检测时隙组中的位置，可以指的是配置有控制信道检测机会的时隙和符号的位置。
比如：{0，1，2，3}是一个时隙组，该时隙组具有控制信道检测机会位于时隙0中，终端可以只在时隙0中进行控制信道检测。
又比如：{0，1，2，3}是一个时隙组，该时隙组具有控制信道检测机会位于时隙0和时隙3中，终端可以在时隙0和时隙3中进行控制信道检测。
由上述实施例可见，可以在所述控制信道检测机会位于在所述检测时隙组中的位置，进行控制信道检测，从而提高了控制信道检测的效率。
进一步地，建立在上述方法的基础上，在执行步骤130之后，还可以包括：
(1-5-1)在对所述检测时隙组中的所有搜索空间均已完成控制信道检测之后，根据检测到的一个或多个控制信息进行共享数据信道的接收或者发送。相应的，对应发送或者接收的时间要求按照最后一个搜索空间结束时间计算，如：数据发送准备时间的要求为N2(单位为符号或者时间)，时隙组内最后一个搜索空间的CORESET结束时间为t2,则不要求终端能够在t2+N2之前进行数据的发送。同理：数据完成接收时间的要求为N1(单位为符号或者时间)，时隙组内最后一个搜索空间的CORESET结束时间为t2,则不要求终端能够在t2+N1之前反馈接收数据的译码结果。
具体地，控制信道检测可以用于现有的Uu接口；也可以用于边链路中，即直连(side link)链路。其中，Uu接口对应的控制信息为DCI；直连(side link)对应的控制信息为SCI(Sidelink Control Information，边链路控制信息)。
比如：在对所述检测时隙组中的所有搜索空间均已完成PDCCH检测之后，根据检测到的一个或多个DCI进行PDSCH的接收。其中，PDCCH用于传输DCI控制信息。
又比如:在对所述检测时隙组中的所有搜索空间均已完成PSCCH(Pysical Sidelink Control Channel，物理直通链路控制信道)检测之后，根据检测到的一个或多个SCI进行PSSCH(Physical Sidelink Shared CHannel，物理直通链路共享信道)的接收。其中，PSCCH用于传输SCI控制信息。
由上述实施例可见，在对所述检测时隙组中的所有搜索空间均已完成控制信道检测之后，根据检测到的一个或多个控制信息进行共享数据信道的接收或者发送，从而降低了终端进行共享数据信道的接收或者发送的复杂度。
图2为本公开实施例提供的一种控制信道检测方法的流程图，该控制信道检测方法可以用于基站。如图2所示，该控制信道检测方法可以包括如下步骤：
步骤210：确定用于控制信道检测的检测时隙组，该检测时隙组用于表征在指定时隙条件时能够共享控制信道检测能力的时隙组。
具体地，控制信道检测可以用于现有的Uu接口；也可以用于边链路中，即直连(side link)链路。
检测时隙组可以指的是多个时隙组成的一个时隙组，并且这些个时隙在指定时隙条件时共享一个控制信道检测能力。
比如：控制信道为PDCCH；用于PDCCH检测的检测时隙组中包括多个时隙，这些个时隙在指定时隙条件时共享一个PDCCH检测能力。
其中，指定时隙条件可以是根据实际情况设置的SCS的一个具体的值或一个取值范围。比如：指定时隙条件为SCS等于120KHz；或指定时隙条件为SCS大于120KHz。
步骤220：确定检测时隙组的搜索空间。
具体地，搜索空间可以指的是检测时隙组中配置了控制信道检测能力的时间范围，其是终端需要进行控制信道检测的时间范围，以及基站需要发送控制信道的时间范围。另外，终端需要进行控制信道检测的搜索空间和基站需要发送控制信道的搜索空间，二者是相同的，这样可以减少终端的实现复杂度。
其中，搜索空间的类型可以是CSS，也可以是USS。搜索空间的数量可以是一个或多个。
比如：SCS等于480KHz，4时隙组成1个检测时隙组，搜索空间的数量为1个，该搜索空间配置在该检测时隙组的时隙2中，而检测时隙组的其他时隙上不配置搜索空间。
又比如：SCS等于960KHz，8时隙组成1个检测时隙组，搜索空间的数量为2个，分配配置在时隙0和时隙4中。
步骤230：在搜索空间内发送控制信道，以使终端在搜索空间内进行控制信道检测。
具体地，基站在控制信道上发送控制信息时，只在检测时隙组中配置了控制信道检测能力的搜索空间内发送控制信息；终端也只在配置了控制信道检测能力的搜索空间内进行控制信道检测。
比如：基站在PDCCH上发送DCI时，只在检测时隙组中配置了PDCCH 检测能力的时隙0上发送DCI，在DCI上，每个DCI可以调度至多4个PDSCH信道数据。与此对应的，终端只在时隙组中配置了PDCCH检测能力的时隙0上检测PDCCH，并根据检测到的DCI，进行PDSCH配置接收，以及相应的解调和译码。
由上述实施例可见，通过确定用于控制信道检测的检测时隙组，该检测时隙组用于表征在指定时隙条件时能够共享控制信道检测能力的时隙组，确定检测时隙组的搜索空间，以及在搜索空间内发送控制信道，以使终端在搜索空间内进行控制信道检测，从而实现了终端以检测时隙组为单元进行控制信道检测，避免了随着SCS的增大而导致的终端在对应的时隙内无法完成控制信令的接收和配置过程，尤其是将一个时隙组的检测能力，集中在该时隙组的搜索空间内，提高了基站的调度灵活性。
进一步地，建立在上述方法的基础上，上述步骤210中的所述指定时隙条件可以包括SCS大于120KHz；所述共享控制信道检测能力用于表征多个时隙对应的控制信道检测能力。
具体地，由于当前标准只定义了SCS在120KHz以下的每个时隙终端检测PDCCH候选信道的数量，所以对于SCS大于120KHz情况，可以采用以时隙组为单元，即多个时隙对应(或称为共享)的控制信道检测能力，并进行搜索空间的配置，来实现相应的控制信道检测。
对应或共享控制信道检测能力可以指的是同一时隙中的多个时隙共享一个控制信道检测能力。比如：控制信道为PDCCH；用于PDCCH检测的检测时隙组中包括多个时隙，这些个时隙在指定时隙条件时共享一个PDCCH检测能力。
由上述实施例可见，在SCS大于120KHz时，可以以检测时隙组为单元进行控制信道检测，即多个时隙共享一个控制信道检测能力，从而避免了随着SCS的增大而导致的终端在对应的时隙内无法完成控制信令的接收和配置过程，满足了无线通信发展的需求。
进一步地，建立在上述方法的基础上，在执行步骤210中确定用于控制信道检测的检测时隙组时，可以包括：
(2-1-1)根据第一节点与第二节点之间的接口协议确定针对所述检测时隙组的第一配置信息。
具体地，第一节点可以是基站，第二节点可以是终端；或者，第一节点可以是终端，第二节点可以是基站。即根据基站和终端之间的接口协议确定针对所述检测时隙组的第一配置信息。
(2-1-2)根据所述第一配置信息确定所述检测时隙组。
由上述实施例可见，可以根据第一节点与第二节点之间的接口协议确定针对所述检测时隙组的第一配置信息，并根据所述第一配置信息确定所述检测时隙组，从而提高了确定检测时隙组的可靠性。
进一步地，建立在上述方法的基础上，上述(2-1-1)中的第一配置信息可以包括：
所述检测时隙组中包含的时隙个数；
所述检测时隙组中最大候选控制信道数量；
所述检测时隙组中最大控制信道单元CCE数量。
其中，还包括下述至少一项：
所述时隙个数与SCS相关联；
所述最大候选控制信道数量与SCS相关联；
最大CCE数量与SCS相关联。
具体的，若所述SCS为480KHz，所述时隙个数为4；若所述SCS为960KHz，所述时隙个数为8。
具体地，上述检测时隙组中包含的时隙个数可以是直接配置的，比如：时隙个数为5或4；此外，所述时隙个数是基于SCS与预设参考SCS的比值所确定的，此时可以以某一特定的SCS为参考，进行倍数扩展的。其扩展公式为：
Figure PCTCN2021081600-appb-000015
其中，μ r为参考SCS，k 0是扩展系数。该扩展系数可以为1、2或其他数值。比如：以0.125ms的长度(SCS＝120KHz)为参考(μ r＝3)，进行倍数扩展。又比如：当SCS＝480KHz时，时隙个数为K μ＝6＝1*2 6-3＝8。
上述最大候选控制信道数量，若控制信道为PDCCH，则最大候选控制信道数量为最大候选PDCCH数量，如上述表4中的
Figure PCTCN2021081600-appb-000016
其中，配置最大候选PDCCH数量，依赖于终端的能力。
上述最大CCE数量，最大CCE数量，如上述表5中的
Figure PCTCN2021081600-appb-000017
其中，配置最大CCE数量，同样依赖于终端的能力。
由上述实施例可见，在确定检测时隙组时，可以根据第一配置信息中的时隙个数、最大候选控制信道数量、最大CCE数量来确定，从而提高了确定检测时隙组的准确性。
进一步地，建立在上述方法的基础上，在执行步骤220中确定检测时隙组的搜索空间时，可以包括：
(2-2-1)根据第一节点与第二节点之间的接口协议确定针对所述搜索空间的第二配置信息。
具体地，第一节点可以是基站，第二节点可以是终端；或者，第一节点可以是终端，第二节点可以是基站。即根据基站和终端之间的接口协议确定针对所述搜索空间的第二配置信息。
(2-2-2)根据所述第二配置信息确定所述搜索空间。
由上述实施例可见，可以根据第一节点与第二节点之间的接口协议确定针对所述搜索空间的第二配置信息，并根据所述第二配置信息确定所述搜索空间，从而提高了确定搜索空间的可靠性。
进一步地，建立在上述方法的基础上，上述(2-2-1)中的第二配置信息可以包括：
第一指示信息，所述第一指示信息用于指示具有控制信道检测机会的检测时隙组；
第二指示信息，所述第二指示信息用于指示控制信道检测机会位于检测时隙组中的指定位置，所述指定位置包括位于检测时隙组中的一个指定时隙或多个指定时隙。其中，多个指定时隙可以指的是至少两个时隙，比如：检测时隙组中的时隙0和时隙3。
具体地，上述第一指示信息可以指示哪些时隙组中有控制信道的检测机 会，当时隙组配置了检测机会，终端在该时隙组中进行控制信道的检测，反之不用在该时隙组中进行控制信道检测。
比如：{0，1，2，3}是一个时隙组，该时隙组具有控制信道检测机会；而{8，9，10，11}是另一个时隙组，该时隙组不具有控制信道检测机会。
其中，在指示具有控制信道检测机会的检测时隙组时，可以使用如下两种配置方式：
方式一，使用位图(bitmap)的方式表示。
比如：使用80bit大小数值，表示10ms的配置(0.125ms为一个时隙组，10ms包含80个时隙组)，1表示对应时隙组需要进行PDCCH检测，0表示对应时隙组不需要进行PDCCH检测。
方式二，使用周期方式指示。其配置参数包括：时隙组周期，和时隙组偏移量。
比如：基站通过高层信令配置了基于时隙组的搜索空间，4个时隙为一组(SCS＝480KHz，每时隙长度是0.125ms/4)。在高层信令配置中，搜索空间周期是4个SG(Slot Group，时隙组),偏移量是2SG。终端在检测PDCCH时，只在周期为4SG，偏移量为2SG的SG上进行PDCCH的检测。
上述控制信道检测机会位于在所述检测时隙组中的位置，可以指的是配置有控制信道检测机会的时隙和符号的位置。
比如：{0，1，2，3}是一个时隙组，该时隙组具有控制信道检测机会位于时隙0中。
可选地，所述第二配置信息可以包括：所述检测时隙组的起始位置偏移(offset)，所述起始位置偏移用于指示所述检测时隙组中包括的各个时隙。
具体地，该起始位置偏移(offset)用于指示一个时隙组是由哪些时隙组成的。
当起始位置偏移(offset)为0,时隙组的时隙个数为4时，在时隙组包括的时隙编号有{4n，4n+1，4n+2，4n+3}。其中，n是大于或等于0的整数。比如：{0，1，2，3}是一个时隙组，{8，9，10，11}是另一个时隙组。
当起始位置偏移(offset)为2,时隙组的时隙个数为4时，在时隙组包 括的时隙编号有{4n+2，4n+1+2，4n+2+2，4n+3+2}。其中，n是大于或等于0的整数。比如：{2，3，4，5}是一个时隙组，{10，11，12，13}是另一个时隙组。
基站可以通过高层信令将起始位置偏移(offset)发送至终端。基站发送控制信道时，确保在“配置的搜索空间内”的时间域上发送控制信道。与此对应的，终端只在配置的时间域上进行控制信道检测。
另外，若起始位置偏移(offset)一直为0时，可作为默认设置，不进行指示。
进一步地，建立在上述方法的基础上，进一步地，建立在上述方法的基础上，在执行步骤230中在搜索空间内发送控制信道时，可以包括：在所述检测时隙组中的一个指定时隙或多个指定时隙上，发送控制信道。
比如：{0，1，2，3}是一个时隙组，该时隙组具有控制信道检测机会位于时隙0中，基站可以只在时隙0上发送控制信道。
又比如：{0，1，2，3}是一个时隙组，该时隙组具有控制信道检测机会位于时隙0和时隙3中，基站可以在时隙0和时隙3上发送控制信道。
进一步地，建立在上述方法的基础上，在执行步骤230中在搜索空间内发送控制信道时，可以包括：
(2-3-1)在所述检测时隙组中的一个或多个搜索空间发送控制信息，以使终端在对所述检测时隙组中的所有搜索空间均已完成控制信道检测之后，根据检测到的一个或多个控制信息进行共享数据信道的接收或者发送。
具体地，控制信道检测可以用于现有的Uu接口；也可以用于边链路中，即直连(side link)链路。其中，Uu接口对应的控制信息为DCI；直连(side link)对应的控制信息为SCI。
比如：基站在所述检测时隙组中的一个或多个搜索空间发送DCI，这样终端可以在对所述检测时隙组中的所有搜索空间均已完成PDCCH检测之后，根据检测到的一个或多个DCI进行PDSCH的接收。其中，PDCCH用于传输DCI控制信息。
又比如:基站在所述检测时隙组中的一个或多个搜索空间发送SCI，这样 终端可以在对所述检测时隙组中的所有搜索空间均已完成PSCCH检测之后，根据检测到的一个或多个SCI进行PSSCH的接收。其中，PSCCH用于传输SCI控制信息。
由上述实施例可见，可以在所述检测时隙组中的一个或多个搜索空间发送控制信息，以使终端在对所述检测时隙组中的所有搜索空间均已完成控制信道检测之后，根据检测到的一个或多个控制信息进行共享数据信道的接收或者发送，从而进一步提高了基站的调度灵活性。
下面针对图1和图2所示的控制信道检测方法，通过具体示例进行说明。
示例1：SCS为480KHz，4时隙为1个时隙组，搜索空间配置在一个时隙中，其位置在第一个时隙。
第一、配置时隙SCS＝480KHz的共享PDCCH检测能力的时隙组
配置共享PDCCH检测能力的时隙组，包括配置最大候选PDCCH检测数量和/或配置最大CCE数量。
其中，每个时隙组包含的时隙个数有两种配置方式：
方式一，直接配置一个时隙组包括的时隙个数。
比如：时隙个数为5或4。
方式二，以某一特定的SCS为参考，进行倍数扩展。其扩展公式为：
Figure PCTCN2021081600-appb-000018
其中，μ r为参考SCS。
比如：以0.125ms的长度(SCS＝120KHz)为参考(μ r＝3)，进行倍数扩展。
又比如：当SCS＝480KHz时，时隙个数为K μ＝5＝2 5-3＝4。
其中，以某一SCS的时长为参考，以时隙组为单位配置PDCCH检测能力好处在于便于实现设计时能够统一考虑架构和模块之间的交互时序要求。
配置最大候选PDCCH数量，依赖于终端的能力，仍然可以以SCS＝120KHz为能力基线。
配置最大CCE数量，同样依赖于终端的能力，仍然可以以SCS＝120KHz为能力基线。
第二、配置时隙SCS＝480KHz的共享PDCCH检测能力的时隙组的搜索空间
搜索空间配置，包括：搜索空间类型(USS或者CSS)；配置需要做PDCCH检测的时隙组。搜索空间类型在搜索空间类型中指示。配置需要做PDCCH检测的时隙组，可以使用如下两种配置方式：
方式一，使用位图(bitmap)的方式表示。
比如：使用80bit大小数值，表示10ms的配置(0.125ms为一个时隙组，10ms包含80个时隙组)，1表示对应时隙组需要进行PDCCH检测，0表示对应时隙组不需要进行PDCCH检测。
方式二，使用周期方式指示。其配置参数包括：时隙组周期，和时隙组偏移量。
比如：如图3所示，基站通过高层信令配置了基于时隙组的搜索空间，4个时隙为一组(SCS＝480KHz，每时隙长度是0.125ms/4)。在高层信令配置中，搜索空间周期T是4个SG(Slot Group，时隙组),偏移量是2SG。终端在检测PDCCH时，只在周期为4SG，偏移量为2SG的SG上进行PDCCH的检测。其中，在有PDCCH检测机会的SG中，PDCCH检测机会位于第一个时隙上。
由上述实施例可见，通过定义以时隙组为单元，确定PDCCH的检测能力，有利于终端侧的设计和实现。
示例2：SCS为960KHz，8时隙为1组，搜索空间配置在2个时隙中，其位置分别在时隙0和4。
第一、配置时隙SCS＝960KHz的共享PDCCH检测能力的时隙组
配置共享PDCCH检测能力的时隙组，包括配置最大候选PDCCH检测数量和/或配置最大CCE数量。
其中，每个时隙组包含的时隙个数有两种配置方式：
方式一，直接配置一个时隙组包括的时隙个数。
比如：时隙个数为5或4。
方式二，以某一特定的SCS为参考，进行倍数扩展。其扩展公式为：
Figure PCTCN2021081600-appb-000019
其中，μ r为参考SCS，k 0是扩展系数。该扩展系数可以为1、2或其他数值。
比如：以0.125ms的长度(SCS＝120KHz)为参考(μ r＝3)，进行倍数扩展。
又比如：当SCS＝960KHz时，时隙个数为K μ＝6＝1*2 6-3＝8。
其中，以某一SCS的时长为参考，以时隙组为单位配置PDCCH检测能力好处在于便于实现设计时能够统一考虑架构和模块之间的交互时序要求。
配置最大候选PDCCH数量，依赖于终端的能力，仍然可以以SCS＝120KHz为能力基线，也可以以SCS＝15KHz为能力基线。
配置最大CCE数量，同样依赖于终端的能力，仍然可以以SCS＝120KHz为能力基线，也可以以SCS＝15KHz为能力基线。
第二、配置时隙SCS＝960KHz的共享PDCCH检测能力的时隙组的搜索空间
1)配置需要做PDCCH检测的时隙组
可以使用如下两种配置方式：
方式一，使用位图(bitmap)的方式表示。
比如：使用80bit大小数值，表示10ms的配置(0.125ms为一个时隙组，10ms包含80个时隙组)，1表示对应时隙组需要进行PDCCH检测，0表示对应时隙组不需要进行PDCCH检测。
方式二，使用周期方式指示。其配置参数包括：时隙组周期，和时隙组偏移量。
比如：基站通过高层信令配置了基于时隙组的搜索空间，4个时隙为一组(SCS＝480KHz，每时隙长度是0.125ms/4)。在高层信令配置中，搜索空间周期是4个SG(Slot Group，时隙组),偏移量是2SG。终端在检测PDCCH时，只在周期为4SG，偏移量为2SG的SG上进行PDCCH的检测。其中，在有PDCCH检测机会的SG中，PDCCH检测机会位于第一个时隙上。
2)配置时隙组内需要做PDCCH检测的时隙
可以采用如下配置方式：
monitoringslotWithinSlotgroupBITSTRING(SIZE(Ku))
其中，Ku为一个时隙组中包括时隙的个数(或者最大个数)
上述字符串定义，当定义为1时，表示对应时隙有PDCCH检测机会，如果为0表示没有检测机会。
比如：如图4和图5所示，monitoringslotWithinSlotgroup配置为10001000，即表示在8个时隙组成的SG中，时隙0和时隙4有PDCCH检测机会。由上述实施例可见，通过定义以时隙组为单元，确定PDCCH的检测能力，有利于终端侧的设计和实现。
示例3：时隙组内配置多个检测机会时的检测能力分配方式
上述示例2中，给出了在一个时隙组中，有两个PDCCH检测机会的情况，在实际配置中，可以在一个时隙组中配置多个PDCCH的检测机会。在这种情况下，候选控制信道数量和CCE数量如何分配，标准协议上需要确定。可以分成如下两个步骤：
步骤A:确定检测机会上需要的候选控制信道数量和CCE数量。
方法1：PDCCH候选控制信道数量按照平均分配，CCE数量按照最大数目配置
方法2：PDCCH候选控制信道数量按照终端上报的能力，CCE数量按照终端上报的能力。
比如：如图6所示，上述示例2中，确定下来的PDCCH候选控制信道数量为M01和M02。其中，M01+M02可以等于配置1个检测机会的PDCCH候选控制信道数量，也可以是大于配置1个检测机会的PDCCH候选控制信道数量。这里不做限制。
步骤B:时隙组内，分配相应的候选信道
假设某个搜索空间的配置中，在一个时隙组内，配置了如下参数：
1：候选PDCCH数量；
比如：该候选PDCCH数量为：
Figure PCTCN2021081600-appb-000020
其中，M L是对应每个CCE聚合等级对应的候选PDCCH数量。
比如：如图7所示，CCE聚合等级为4的情况下，候选PDCCH数量PDCCH为4，分别为PDCCH1、PDCCH2、PDCCH3、PDCCH4；CCE聚合等级在8的情况下，候选PDCCH数量为2，分别为PDCCH5、PDCCH6；CCE聚合等级为16时，候选PDCCH数量为1，具体为PDCCH7。即总共候选PDCCH数量为7。
2：K个候选检测机会；上述示例2中，K为2。
分配方法如下：
1)将候选PDCCH的进行编号，顺序为：先以相同CCE的聚合等级内的候选PDCCH进行排序，CCE索引进行增序；然后以不同CCE的聚合等级间的候选PDCCH进行排序，CCE的聚合等级为增效，可参见图7所示。
2)假设时隙组中，有M total个PDCCH检测机会。(如示例1中，K＝1，示例2中K＝2)。
则每个PDCCH检测机会的起始候选PDCCH编号为：
Figure PCTCN2021081600-appb-000021
Figure PCTCN2021081600-appb-000022
比如：如图8所示，M01＝3，M02＝4，两个PDCCH检测机会上，分配的PDCCH分别是：时隙0＝{PDCCH1，PDCCH2，PDCCH3}，时隙4＝{PDCCH4，PDCCH5，PDCCH6，PDCCH7}。即在时隙0上，终端需检测的PDCCH为：CCE聚合级别为4的候选PDCCH1、PDCCH2、PDCCH3；在时隙4上，终端需要检测的PDCCH为：CCE聚合级别为4的候选PDCCH4，聚合级别为8的候选PDCCH5、PDCCH6，聚合级别为16的候选PDCCH7。
由上述实施例可见，使用不同CCE聚合级别分配在不同的PDCCH检测机会上，使得基站调度更加灵活，能够调度更多的终端和数据包。
另外，上述实施例中，
1：候选PDCCH的顺序，可以以CCE聚合等级从小到大排序，也可以 按照CCE聚合级别从大到小排序。
2：候选PDCCH的顺序，可以以CCE聚合等级从小到大排序，也可以按照DCI大小进行排序。比如当有两个DCI大小不同时，可以分配到不同的PDCCH检测机会上。
3：当一个时隙组中有多个PDCCH检测机会时，基站和终端可以通过协议，将所有的检测机会都检测完后再上报给DCI解析模块，即当计算时隙或者定时时，以最后一个PDCCH检测机会的符号计算为准。
4：本实施例的PDCCH检测能力分配，可以在一个搜索空间中分配，也可以在不同的搜索空间中分配。比如：搜索空间S1，检测CCE聚合级别为4的候选PDCCH；搜索空间S2检测CCE聚合级别为8和16的候选PDCCH5。
还有，上述实施例中，
在一个时隙组中有共享PDCCH检测能力，在一个DCI，有可能调度的PDSCH/PUSCH在本时隙组的时隙上发送，也与可能在其它时隙组上调度。调度信令中，增加时隙组的调度指示，方法如下：
1：当调度是PDSCH时，使用k0的数值(如调度的是PUSCH，重用k2的数值)，表示时隙组的偏移量(groupslot-offset)，时隙组内的时隙偏移量用bitmap的方式。
比如：如图9所示，调度参数设置为：k0,groupslot[K μ]，其中，K μ和时隙组中包含的时隙个数相关。
其中，k0＝2，则表示调度时隙组为1+k0＝3；
groupslot为0101，即表示在调度的时隙组中，时隙0和时隙2没有数据调度；时隙1和时隙3有数据调度。
进一步的，groupslot-offset信息可以指示在DCI中。
2：当调度是PDSCH时，新增时隙组的指示，即groupslot-index。时隙组的数值范围进行限制，如限制在0、1、2、3、…、16。
比如：如图10所示，groupslot-index为2，即表示时隙组的偏移量为2，即在时隙1+2＝3的时隙组上有PDSCH调度。
k0指示时隙组内的偏移量，若k0＝3，即在调度时隙组内，在时隙3上。
