背景技术
目前，组公共下行物理共享信道(Physical downlink shared channel，PDSCH)可以通过组公共物理下行控制信道(Physical downlink control channel，PDCCH)进行调度，而组公共PDCCH需要在公共搜索空间(common search space，CSS)set中发送。

1)搜索空间集(search space set，SS set)和SS set类型
PDCCH承载着下行控制信息(Downlink Control Information，DCI)。在LTE中，PDCCH频域上占据全部带宽，时域上占据每个子帧的前1-3个符号，由资源的多少动态调度。在NR中，PDCCH若沿用LTE的方式，继续占据全部带宽，无疑是资源的浪费，而且会对UE提出很高的要求，不利于降低UE成本，所以NR中PDCCH会在BWP内，而且时域也不是占据固定的一些时隙。
一般的，SS为PDCCH的时域资源位置，而CORESET为PDCCH的频域资源位置。一个或多个SS组成一个SS set，每个SS set会关联一个CORESET ID，一个CORESET可能被多个SS set关联。
SS set有很多类型，首先分为公共搜索空间(Common Search Space，CSS)set和UE特定搜索空间(UE-Specific Search Space，USS)set，具体类型如下：
Type0-PDCCH CSS set:用于系统信息块(system information block，SIB)1的接收；
Type0A-PDCCH CSS set:用于Other SIB的接收；
Type1-PDCCH CSS set:RA的msg2和msg4的调度；
Type2-PDCCH CSS set:用于寻呼(Paging)；
Type3-PDCCH CSS set:用途很多，例如，INT-RNTI，SFI-RNTI，TPC-PUSCH-RNTI，TPC-PUCCH-RNTI，TPC-SRS-RNTI，CI-RNTI，PS-RNTI，不同的扰码对应不同的功能；
USS set:用于UE Specific PDCCH的接收。
不同类型的search space会有不同RNTI加扰的PDCCH，对应上述不同的用途。从上述的描述可以看出，CSS为小区公共的search space，由小区所有用户共享，多用于需要广播的信息。在UE监测search space的时候，CSS优先于USS。此外，USS set以及CCE index是UE特定的，即对于不同UE的USS set，其CCE index是UE特定的，而CSS set以及CCE index是组公共的，即对于一个CSS set，不同UE确定的CCE index是相同的。
2)SS的确定
通常情况下，搜索空间的确定主要分为两步：
第一步，据搜索空间集合的配饰信息确定配饰的候选PDCCH集合中每个候选PDCCH在CORESET内的CCE索引。
第二步，根据预设规则在配置的候选PDCCH集合中确定待检测的候选PDCCH集合，该待检测的候选PDCCH集合为配置的候选PDCCH集合的子集。
示例性的，NR中每个候选PDCCH在CORESET内的CCE的索引，是基于给定的搜索空间函数确定。其中，该搜索空间函数沿用了LTE中确定EPDCCH的函数。如此，实现了把候选PDCCH等间隔地分散在CORESET内的CCE集合上。
具体的，对于关联CORSET的搜索空间集合s，在时隙，聚合等级为L的候选PDCCH的CCE索引由下式给出：

3)BD/CCE盲检测能力
PDCCH可支持多种下行控制信息格式和聚合等级大小，而这些信息对于UE而言无法提前获得，因此UE需要对PDCCH进行盲检测。在NR中，服务小区内每个下行BWP内，最多可配置10个搜索空间集合。此外，在NR中增加了搜索空间时域配置信息，UE需要根据配置的搜索空间集合在时域的位置检测候选PDCCH。
对于在配置的候选PDCCH集合内确定待检测的子集，需要定义UE的盲检测能力的上限，其中，该盲检测能力包括每个时隙内和/或每个span(一个时隙内的连续几个符号)检测的候选控制信道的BD数量和不重叠的CCE的数量。如下表1所示，该表1表征了服务小区内每个时隙内UE盲检测能力与子载波间隔的关系。

另外，在NR Rel-16版本中，盲检测能力还可以定义为每个span内UE盲检测能力。其中，span定义为一个时隙内若干个连续的OFDM符号。
其中，最大候选控制信道的数量限制了UE进行盲检测译码的复杂度，而无重叠的CCE的数量限制了UE进行信道估计的复杂度。因此，当某个时隙所有配置的搜索空间的BD/CCE超出UE能力时(即BD/CCE overbooking)，根据一定的规则确定需要检测的搜索空间，其余搜索空间则不需要检测。
4)组公共PDSCH
目前，NR技术已经历经了两个版本Rel-15和Rel-16的演进，在这两个版本中一直没有支持广播/多播(broadcast/multicast)特性，但是有很多重要的使用场景，例如公共安全和关键任务(public safety and mission critical)、V2X应用(V2X applications),透明IPv4/IPv6多播传送(transparent IPv4/IPv6multicast delivery)、IPTV、无线软件传送(software delivery over wireless)、组通信和物联网应用(group communications and IoT applications)等中broadcast/multicast特性可以提供实质性的提高，尤其是在系统效率和用户体验方面。因此，在接下来的Rel-17版本中，NR将引入广播/多播特性。广播多播业务主要通过组公共PDSCH进行传输。UE可以同时接收组公共PDSCH和单播PDSCH。组公共PDSCH可以通过组公共PDCCH进行调度，组公共PDCCH所在的SS的CCE index的确定方法是组公共的。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的架构图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment， UE)，终端11可以是手机、平板电脑(Tablet Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：智能手表、手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的PDCCH盲检测方法进行详细地说明。
图2示出了本申请实施例提供的一种PDCCH盲检测方法的流程示意图，如图2所示，该PDCCH盲检测方法可以包括如下步骤：
步骤101：网络侧设备为UE配置目标搜索空间集。
在本申请实施例中，上述目标搜索空间集满足目标条件；上述目标条件包括：在至少一个传输时间单元(例如，时隙或span)内的候选PDCCH对应的检测对象超出UE的盲检测能力时，不检测该目标搜索空间集内的候选PDCCH。
在本申请实施例中，上述检测对象包括：CCE或BD。
可以理解，在某个传输时间单元内的候选PDCCH对应的CCE或BD数量超出UE的盲检测能力时，则可以根据一定的规则确定不检测目标搜索空间集内的候选PDCCH，即在CCE或BD overbooking时，可以不检测该目标搜索空间集内的候选PDCCH，或者说，不检测该候选PDCCH的搜索空间集(即目标搜索空间集)。换句话说，上述目标搜索空间集允许CCE或BD overbooking。
例如，在某个传输时间单元UE被配置了一个或多个CSS set(例如，可以包括以下至少一项：Type0A-PDCCH CSS set，Type1-PDCCH CSS set，Type2-PDCCH CSS set，Type3-PDCCH CSS set)，目标搜索空间以及一个USS set，且该传输时间单元内所有配置的SS set的BD/CCE超出了UE的盲检测能力，则UE不检测USS set内的PDCCH(假设目标搜索空间集的检测优先级比USS set高)，如果该时隙内除了USS set之外，其他的SS set对应的BD/CCE不超出UE的盲检测能力，则UE在该传输时间单元检测该目标搜索空间集内的PDCCH，否则，如果超出了UE的盲检测能力，则不检测该目标搜索空间集内的PDCCH。
可选地，在本申请实施例中，网络侧设备在为UE配置每个SS set时，需要配置其SS set类型。NR中，只有两个SS set类型,即CSS set或者USS set，具体配置参数如下：CSS  set不能overbooking，USS set可以overbooking，且在overbooking时，可以根据USS set的ID大小，UE可以不检测ID大的SS set内的PDCCH。
因此，为了能够有效调度传输多播/广播业务的组公共PDSCH的组播PDCCH，本申请实施例定义了一种的新的SS set(即本申请中的目标搜索空间集，例如，MBS CSS set，或Type4-PDCCH CSS set等，具体名称不做限定)，该目标搜索空间集可以满足以下至少一项：
1)目标搜索空间集的CCE index是组公共的，例如，在确定某个PDCCH在CORESET内的CCE index时的参数
Figure PCTCN2022082493-appb-000005
或n g-RNTI。
2)当某个时隙/span配置的候选PDCCH超出UE的BD/CCE能力，UE可以按照一定的原则，确定不检测该SS set内的候选PDCCH；
3)目标搜索空间集的优先级(即，在BD/CCE overbooking时，该SS set相对于其他SS set不检测的先后顺序)可以配置。
可选地，在本申请实施例中，上述目标搜索空间集可以为：公共搜索空间集，也可以为UE专用搜索空间集。
进一步可选地，在本申请实施例中，在上述目标搜索空间集为公共搜索空间集的情况下，上述步骤101可以通过如下步骤101a或步骤101b来进行配置：
步骤101a：网络侧设备通过高层参数为公共搜索空间集配置目标参数。
其中，配置有目标参数的公共搜索空间集满足上述目标条件。
可以理解，配置有目标参数的CSS set，可以认为该CSS set不同于传统的CSS set，该CSS set可以允许CCE或BD overbooking，且在BD/CCE overbooking时，UE可以不检测该类CSS set内的PDCCH。
示例性的，上述目标参数可以为特定参数，也可以为标签，本申请实施例对此不做限定。
步骤101b：网络侧设备通过目标IE配置公共搜索空间集。
其中，配置后的公共搜索空间集满足上述目标条件。
可以理解，本申请实施例通过引入新的IE配置CSS set，通过该IE配置的CSS set可以BD/CCE overbooking，且在BD/CCE overbooking时，UE可以不检测该类CSS set内的PDCCH。
在相关技术中，对于CSS set，可以通过配置该CSS set的RRC参数，将该CSS set进一步分为不同的CSS set类型。类似的，在本申请实施例中，网络侧设备可以通过某个特定的IE配置CSS set，使得该CSS set不同于上述相关技术所提及的CSS set，例如，通过在PDCCH-config中引入参数MBSSearchspace来配置一个CSS set，通过该方式配置的CSS set(例如定义为type 4-PDCCH CSS set)可以仅用于调度组公共PDSCH，且可以BD/CCE overbooking，并在BD/CCE overbooking时，UE可以不检测该其CSS set中的候选PDCCH。
进一步可选地，在本申请实施例中，在上述目标搜索空间集为公共搜索空间集的情况下，当CSS set仅关联了目标DCI格式或目标RNTI时，该类CSS set可以BD/CCE  overbooking，且在BD/CCE overbooking时，UE可以不检测该类CSS set内的PDCCH。示例性的，上述目标DCI格式用于调度组公共PDSCH的DCI格式；或者，上述目标RNTI满足以下至少一项：组公共PDSCH使用的RNTI，调度组公共PDSCH的组公共PDCCH使用的RNTI。
需要说明的是，上述的目标DCI格式可以是一个或多个，但这些DCI格式仅用于调度组公共PDSCH，不用于其他调度。类似的，上述目标RNTI可以是一个或多个，但是这些RNTI仅用于组公共PDSCH调度，不用于其他调度。
相关技术中，网络侧设备在配置CSS set或USS set时，会配置其SS set内需要检测的DCI格式。例如，CSS set可以配置DCI格式：0_0/1_0/2_0/2_1/2_2/2_3等，USS set可以配置DCI格式：0_0/1_0/1_1/1_2/0_2/1_2等。基于此，假设组公共PDSCH是通过DCI格式X调度的(应注意的是，DCI格式X不用于其他调度)，本申请实施例可以定义：当一个CSS set仅配置了DCI格式X时，说明该CSS set仅用于组公共PDSCH的调度，即该类CSS set可以配置在某个传输时间单元可以BD/CCE overbooking，且在BD/CCE overbooking时，可以按照一定的原则选择不检测该CSS set内的候选PDCCH。
类似的，网络侧设备也可以通过配置CSS set关联的RNTI，来定义CSS set。例如，当某个CSS set仅关联了某特定RNTI时，上述CSS set可以overbooking或UE不检测其中的候选PDCCH。
进一步，结合图2，本申请实施例提供的一种PDCCH盲检测方法的流程示意图，该PDCCH盲检测方法可以包括如下步骤：
步骤201：UE获取目标搜索空间集配置。
步骤202：UE根据目标搜索空间集配置，进行PDCCH盲检测。
在本申请实施例中，上述目标搜索空间集配置是指：目标搜索空间集的配置信息，用于指示该目标搜索空间集。
在本申请实施例中，上述目标搜索空间集满足目标条件；上述目标条件包括：在至少一个传输时间单元内的候选PDCCH对应的检测对象(即CCE或BD)超出UE的盲检测能力时，不检测该目标搜索空间集内的候选PDCCH。
可选地，在本申请实施例中，上述目标条件还包括：目标搜索空间集对应的CCE索引为组公共的。
可选地，在本申请实施例中，在上述目标搜索空间集为公共搜索空间集的情况下，上述公共搜索空间集满足以下至少一项：
该公共搜索空间集配置有目标参数；
该公共搜索空间集是网络侧设备通过目标IE配置的。
可选地，在本申请实施例中，在上述公共搜索空间集仅关联目标DCI格式和/或目标RNTI的情况下，该公共搜索空间集满足目标条件。
进一步可选地，在本申请实施例中，上述目标DCI格式用于调度组公共PDSCH的DCI格式；或者，上述目标RNTI满足以下至少一项：组公共PDSCH使用的RNTI，调度组公 共PDSCH的组公共PDCCH使用的RNTI。
可选地，在本申请实施例中，上述步骤202可以包括如下步骤202a：
步骤202a：UE根据该目标搜索空间集的目标优先级信息，确定是否检测该目标搜索空间集内的候选PDCCH。
其中，上述目标优先级信息用于表征该目标搜索空间集相对于其他搜索空间集不检测的先后顺序。应注意的是，上述目标优先级信息还可以用于表征该目标搜索空间集相对于其他搜索空间集检测的先后顺序，本申请实施例对此不做限定。
在本申请实施例中，上述目标优先级信息是：在至少一个传输时间单元内的候选PDCCH对应的检测对象超出UE的盲检测能力时(即在CCE或BD overbooking时)，基于目标搜索空间集的优先级配置信息或集合标识信息，以及预定规则确定的。
进一步可选地，在本申请实施例中，上述集合标识信息包括：目标搜索空间集的集合标识值；上述预定规则包括以下至少一项：
优先不检测集合标识值大的搜索空间集内的候选PDCCH；
优先不检测集合优先级小于目标搜索空间集的搜索空间集内的候选PDCCH。
示例性的，本申请实施例可以配置该目标搜索空间集的检测优先级，例如，可以为该目标搜索空间即配置一个索引值(该值可以不同于目标搜索空间集的集合标识值ID)，可以设定集合标识值比该索引值大或等于的SS set的优先级比该SS set的优先级小，反之，集合标识值比该索引值小的SS set的优先级比该SS set的优先级大。通常情况下，优先不检测集合优先级小于目标搜索空间集的搜索空间集内的候选PDCCH。可以理解，上述索引值可以为：针对公共搜索空间集，为公共搜索空间集配置的用于表征其检测优先级的标识值。
通过情况下，配置的优先级越大，则表明UE越要检测，优先级越小，则表明UE可以不检测。当然，实际应用中，可以按照实际需求来进行设定，本申请实施例对此不做限定。
示例性的，在BD/CCE overbooking的场景下，在确定是否检测目标搜索空间集内的候选PDCCH时，可以根据该SS set的ID值大小或者为该SS set配置的优先级配置信息，来用于确定BD/CCE overbooking时，该SS set相对于其他SS set不检测的先后顺序。
示例性的，UE按照SS set的ID(不管是USS还是CSS)，UE可以优先不检测ID大的SS内的候选PDCCH。
示例性的，某个时隙网络侧设备配置了3个type 3-PDCCH CSS set(其ID分别为ID 0，ID 1，ID 2)，2个目标搜索空间集(其SS set ID分别为ID 4，ID 5)，以及2个USS set(其SS set ID分别为ID 3，ID 6)。且在该时隙type 3-PDCCH CSS set，目标搜索空间集，以及USS set的BD/CCE超出了UE的盲检测能力，则UE优先不检测USS set 6(即ID 6对应的USS set)内的PDCCH。如果除了USS set 6之后,剩余的SS set的BD/CCE仍然超出UE的BD/CCE能力，则UE不检测ID为5的目标搜索空间集，如果不超出UE的盲检测能力，则UE盲检测剩余的SS set内的PDCCH。如果除了USS set 6和ID为5的目标搜 索空间集，剩余的SS set的BD/CCE仍然超出UE的BD/CCE能力，则UE不检测ID为4的目标搜索空间集，如果不超出UE的盲检测能力，则UE盲检测剩余的SS set内的PDCCH。依次类推，UE按照SS set的ID大小确定不检测的SS set(只包含目标搜索空间集和USS set)，ID大的优先不检测。
示例性的，以CSS set为例，网络侧设备配置或指示该CSS的优先级(例如相对于USS的优先级)。举例说明，假设基站指示该CSS set的优先级大于USS set X，则表示UE优先不检测ID比X大以及X的USS，此时，如果BD/CCE数目仍然超出UE盲检测能力，则UE不检测该CSS set内的候选PDCCH，然后，如果BD/CCE数目仍然超出UE盲检测能力，则UE不检测ID比X小的USS set内的候选PDCCH，直至满足UE盲检测能力。
在本申请实施例提供的PDCCH盲检测方法中，网络侧设备通过为UE配置一种可以overbooking的目标搜索空间集(即，在至少一个传输时间单元内的候选PDCCH对应的检测对象超出UE的盲检测能力时，不检测该目标搜索空间集内的候选PDCCH)，使得UE可以基于该目标搜索空间集配置进行盲检测，以满足实际系统中的业务需求，提高了通信系统的有效性。
需要说明的是，本申请实施例提供的PDCCH盲检测方法，执行主体可以为PDCCH盲检测装置，或者，该PDCCH盲检测装置中的用于执行PDCCH盲检测方法的控制模块。本申请实施例中以PDCCH盲检测装置执行PDCCH盲检测方法为例，说明本申请实施例提供的PDCCH盲检测方法的装置。
