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。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
在介绍本申请技术方案之前，先对本申请涉及的一些技术知识进行介绍说明。
在大部分场景下，一个DCI调度的资源限制在一个载波上。当引入一个DCI调度多个服务小区的PDSCH/PUSCH的方案时，会出现一个DCI调度的资源对应在多个载波或小区上。反之，多个载波对应了一个DCI。本申请提供了在这种“多个载波对应一个DCI”的情况下，如何实现PDCCH检测的技术方案。
图1示出了本申请一个实施例提供的移动通信系统的示意图。该移动通信系统可以包括：终端10和接入网设备20。
终端10的数量通常为多个，每一个接入网设备20所管理的小区内可以分布一个或多个终端10。终端10可以包括各种具有移动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它处理设备，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端。
接入网设备20是一种部署在接入网中用于为终端10提供移动通信功能的装置。接入网设备20可以包括各种形式的宏基站，微基站，中继站，接入点，定位管理功能实体(Location Management Function，LMF)等等。在采用不同的无线接入技术的系统中，具备接入网设备功能的设备的名称可能会有所不同，具体的在5G NR系统中，称为gNodeB或者gNB。随着 通信技术的演进，“接入网设备”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端10提供移动通信功能的装置统称为接入网设备。接入网设备20与终端10之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。接入网设备20的数量可以有多个，两个邻近的接入网设备20之间也可以通过有线或者无线的方式进行通信。终端10可以在不同的接入网设备20之间进行切换，也即与不同的接入网设备20建立连接。
本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
终端10处于多个小区的覆盖下，比如小区X和小区Y的覆盖下。接入网设备20可以使用一个DCI调度多个载波或小区上的资源。由于一个服务小区对应一个载波，在本申请中“服务小区”和“载波”可以视为相同的概念。
图2示出了本申请一个示例性实施例提供的PDCCH检测方法的流程图。本实施例以该方法应用于终端来举例说明。该方法包括：
步骤202：基于载波组合进行PDCCH检测，载波组合包括一个或多个载波。
终端基于一个(被调度的)载波组合进行PDCCH检测。一个载波组合包括一个或多个载波。多个载波是指至少两个载波。一个被调度的载波组合上的全部或部分频域资源是由一个PDCCH(或一个DCI)调度实现的。
即便在一个载波组合仅包括一个载波的情况下，该载波也是视为一个载波组合来进行处理。载波组合可以为一个或多个。
在一些实施例中，(被调度的)载波组合是由高层信令预配置的。
在一些实施例中，属于同一个(被调度的)载波组合的载波配置有相同的子载波间隔。
在一些实施例中，属于同一个(被调度的)载波组合的载波配置有同一个PUCCH组。在属于同一个PUCCH组的情况下，不同一个载波组合中的各个载波可以使用相同的PUCCH资源进行混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)反馈。
参考图3，假设调度小区包括：服务小区1、服务小区3和服务小区4。被调度小区包括：服务小区1、服务小区2、服务小区3、服务小区4和服务小区5。其中，调度小区是下发PDCCH的服务小区，被调度小区是PDCCH调度的服务小区。调度小区和被调度小区中相同编号的服务小区是指同一个服务小区。图3中的箭头是指调度关系，服务小区1调度服务小区1属于当前载波调度，服务小区1调度服务小区2属于跨载波调度。
网络设备通过高层信令为终端配置5个服务小区，5个服务小区属于相同的小区组。比如，相同的小区组是属于同一个主小区组(MasterCellGroup，MCG)，或者相同的小区组是属于同一个辅小区组(SecondaryCellGroup，SCG)，或者相同的小区组属于同一个主PUCCH组(PrimaryPUCCHGroup)。
参考图3，被调度的载波组合包括如下6种载波组合中的任意一种载波组合：
载波组合1即为：服务小区1；
载波组合2即为：服务小区2；
载波组合3即为：服务小区3；
载波组合4即为：服务小区4；
载波组合5即为：服务小区5；
载波组合6即为：服务小区4+服务小区5。
其中，服务小区1作为调度小区，可以调度服务小区1，也可以跨载波调度服务小区2；服务小区3作为调度小区，可以调度服务小区3；服务小区4作为调度小区，可以单独调度服务小区4，也可以单独调度服务小区5，还可以同时调度服务小区4和5。在载波组合1至5中，每个载波组合中的载波数量为1；在载波组合6中，载波数量为2。
综上所述，本实施例提供的方法，通过以载波组合为单位进行PDCCH检测，不仅在一个DCI调度多个服务小区的PDSCH和/或PUSCH的场景中，实现对多个载波上的PDCCH检测，还能够将PDCCH检测过程的相关设计均定位在载波组合上，避免区分“一个DCI调度一个载波”和“一个DCI调度多个载波”的不同情况进行不同设计，降低通信协议的复杂性。
PDCCH检测过程至少包括如下三个部分：
·PDCCH配置；
终端接收PDCCH配置，获得PDCCH盲检测的时频区域，映射方式，DCI格式和聚合等级等信息中至少一种。具体地，PDCCH-Config配置了终端在接收用户专属控制信息和组公共控制信息时所需要的一系列用户专属参数，并且是针对每个服务小区的每个带宽部分(BandwidthPart，BWP)独立配置。该参数包含了核心资源集(CORESET)配置，搜索空间(SearchSpace)配置，组公共控制信息的配置，具体的发射功率控制(TransmitPowerControl，TPC)相关配置，下行链路抢占(downlinkPreemption)配置，上行链路取消(uplinkCancellation)配置，以及搜索空间切换(searchspace switching)相关的配置。
·DCI大小对齐；
新空口系统(NewRadio，NR)支持终端在网络侧配置的搜索空间集合(SearchSpaceSets)中进行PDCCH盲检测。PDCCH盲检测是指终端在检测到PDCCH承载的DCI之前，并不知道网络设备下发的DCI的格式信息，因此需要使用一些固定的DCI大小(DCIsize)对搜索空间集合中的候选PDCCH进行盲检。为了降低终端在盲检PDCCH时的复杂度，需要进行DCI大小对齐。
具体的，当终端被配置了多于3种的采用C-RNTI加扰的DCI格式，通过DCI大小对齐，使得DCI大小的数目保持在3个。比如，在存在4种采用C-RNTI加扰的DCI格式的情况下，将其中一种DCI格式的大小进行补长或截短，使之与另外三种DCI格式中的某一种DCI格式的大小相同。
这样终端在盲检测时，仅需针对3种DCI大小进行盲检，无需针对每一种DCI格式进行盲检测。终端可以通过读取DCI中的内容区别同一个DCI大小的不同DCI格式。
相关技术中的通信协议约定，对于一个被调度的载波或小区，DCI大小的数目不大于4；以及，采用C-RNTI加扰的DCI大小的数目不大于3。
·确定终端的PDCCH检测能力。
为了保证网络侧配置的PDCCH的检测次数在终端实现的能力范围内，NR协议还约定了PDCCH的检测能力，意在约束网络侧的PDCCH配置。当网络侧配置的待检测PDCCH所需的盲检测或信道估计超过终端的PDCCH检测能力，则终端停止在剩余的潜在资源上检测PDCCH。
针对PDCCH配置：
图4示出了本申请一个示例性实施例提供的PDCCH检测方法的流程图。本实施例以该方法应用于终端来举例说明。该方法包括：
步骤402：终端接收网络设备发送的与载波组合对应的PDCCH配置；
继续参考图3，终端接收网络设备为服务小区1～5，以及服务小区4和5共6种组合分别配置的PDCCH配置。与载波组合对应的PDCCH配置，配置有PDCCH盲检测的时频区域，映射方式，DCI格式和聚合等级等信息中至少一种。PDCCH配置针对一个载波组合。针对一个载波组合，PDCCH配置可以配置有一个或多个，在配置有多个PDCCH配置的情况下，多个PDCCH配置与该载波组合的多个BWP一一对应。
在一个示例中，PDCCH配置包括如下信息中的至少一种：
·与载波组合对应的PDCCH配置信息(PDCCHConfig)；
·与载波组合对应的控制资源集(ControlResourceSet，或CORESET)；
·与载波组合对应的搜索空间集(SearchSpaceSet，或，SearchSpace)。
在该实施例中，网络设备配置第一PDCCH配置给服务小区1，网络设备配置第二PDCCH配置给服务小区2，网络设备配置第三PDCCH配置给服务小区3，网络设备配置第四PDCCH配置给服务小区4，网络设备配置第五PDCCH配置给服务小区5，网络设备配置第六PDCCH配置给服务小区4和5的载波组合。
具体的，网络设备配置第一PDCCH-Config，第一SearchSpace和第一ControlResourceSet给服务小区1；配置第二PDCCH-Config，第二SearchSpace和第二ControlResourceSet给服务小区2，…，网络设备还配置第六PDCCH-Config，第六SearchSpace和第六ControlResourceSet给服务小区4和5的载波组合。
在一些实施例中，SearchSpace和ControlResourceSet是PDCCH-Config中的两个信息域。在一些实施例中，PDCCH配置包括PDCCHConfig的全部信息域；在一些实施例中，PDCCH配置仅包括Coreset和/或SearchSpace，也即PDCCHConfig的部分信息域；在一些实施例中，PDCCH配置不仅包括Coreset和SearchSpace，还包括一些新增信息域或信息元素(Information Element)，本申请实施例对此不加以限定。
在一些实施例中，终端还接收网络设备发送的与载波组合对应的跨载波配置，跨载波配置包括：与载波组合对应的载波指示域(CarrierIndicatorfield，CIF)取值。
在图3所示的例子中，网络设备配置服务小区1、服务小区2、服务小区4、服务小区5、服务小区4和服务小区5的载波组合配置跨载波配置。比如，该跨载波配置为CrossCarrierSchedulingConfig。网络设备配置第一跨载波配置给服务小区1，网络设备配置第二跨载波配置给服务小区2，…，网络设备配置第五跨载波配置给服务小区4和5的载波组合。
具体地，网络设备配置第一CrossCarrierSchedulingConfig给服务小区1，网络配置第二CrossCarrierSchedulingConfig给服务小区2，…，网络配置第五CrossCarrierSchedulingConfig给服务小区4和5的载波组合。
在跨载波配置，(在一些实施例中可以表示为CrossCarrierSchedulingConfig)中，服务小区1,2,4,5以及服务小区4和5的载波组合分别配置一个CIF取值，一个载波组合对应一个CIF取值。如图3所示的示例，具体的配置结果为：
表一跨载波配置示例
Figure PCTCN2021143899-appb-000001
其中，服务小区1、服务小区2、服务小区4、服务小区5对应的CIF取值均为1，服务小区4和5对应的CIF取值为2。
步骤404：终端基于网络设备对载波组合的PDCCH配置，进行PDCCH盲检测；
在该实施例中，终端根据被调度小区：服务小区1、服务小区2、服务小区3、服务小区4、服务小区5以及服务小区4和5的六种载波组合分别对应的PDCCH配置，在相应的时频资源上进行PDCCH检测。
其中，控制资源集配置了候选PDCCH的频域位置和时域长度。搜索资源集配置了候选PDCCH的时域位置。
在被调度的载波组合包括服务小区4和5的载波组合6情况下，基于载波组合6的PDCCH配置，进行PDCCH盲检测。
步骤406：在PDCCH盲检测通过的情况下，通过PDCCH携带的载波指示域CIF取值确定被调度的载波组合。
在一些实施例中，对于服务小区1,2,3,4,5的5个载波组合、以及服务小区4和5的载波组合中的任意一个载波组合，根据与被调度的载波组合对应的PDCCH配置进行PDCCH检测，并通过读取CIF取值确定被调度的载波组合。以表一的跨载波配置为例，假设终端在服务小区4上根据服务小区4和服务小区5的载波组合对应的PDCCH配置检测PDCCH，当PDCCH盲检测通过，即循环冗余校验(Cyclic Redundancy Check，CRC)校验通过，则终端进一步通过读取CIF取值，确实该PDCCH(或DCI)是否调度了服务小区4和服务小区5的载波组合。当CIF取值为2时，表示该PDCCH调度了服务小区4和服务小区5的载波组合。
示意性的，在载波组合中的载波数量为至少两个的情况下，终端还进一步确定该载波组合中的调度载波，该调度载波可以是载波组合中的所有载波，或者，该调度载波可以是载波组合中的部分载波，或者，该调度载波可以是载波组合中的一个载波。
■情况1，用于调度服务小区4和服务小区5的载波组合的DCI所指示的频域资源包含服务小区4的部分或全部频域资源，和服务小区5的部分或全部频域资源。
■情况2，用于调度服务小区4和服务小区5的载波组合的DCI所指示的频域资源可以包含服务小区4的部分或全部和服务小区5的部分或全部频域资源，也可以仅包含服务小区4的部分或全部频域资源，也可以仅包含服务小区5的部分或全部频域资源。
上述两种方式可以由网络配置决定，兼顾PDCCH检测能力划分与DCI传输效率的影响。情况1，单独调度服务小区4，或者调度服务小区5，与调度服务小区4和5的载波组合三种方式互相独立使用，可以避免DCI存在冗余信息，降低DCI传输效率。情况2，允许调度服务小区4和5的载波组合的PDCCH，也可以单独调度服务小区4或者5，即允许在无需配置的情况下单独调度服务小区4和服务小区5的PDCCH，这样被调度载波组合的数目可以减少，进行影响PDCCH检测能力的划分。
上述方式也可以通过通信协议的约定限制，具体的通信协议会约束仅允许情况1出现。
综上所述，本实施例提供的方法，通过以载波组合为单位进行PDCCH检测，不仅在一个DCI调度多个服务小区的PDSCH和/或PUSCH的场景中，实现以载波组合为单位对调度一个或多个载波的PDCCH检测，还能够将PDCCH检测过程的相关设计均定位在载波组合上，避免区分“一个DCI调度一个载波”和“一个DCI调度多个载波”的不同情况进行不同设计，降低通信协议的复杂性。
本实施例提供的方法，通过以载波组合为单位进行PDCCH配置，可以根据实际的调度情况来进行区别化配置，有利于平衡不同载波组合情况下的PDCCH能力划分，提升PDCCH传输效率。
本实施例提供的方法，通过设置属于同一个载波组合的载波配置有相同的子载波间隔，属于同一个载波组合的载波配置有同一个PUCCH组，能够高效共用同一个DCI中的时域资 源分配(TimeDomain Resource Allocation，TDRA)，PUCCH资源相关的信息域。
针对DCI大小对齐：
图5示出了本申请一个示例性实施例提供的PDCCH检测方法的流程图。本实施例以该方法应用于终端来举例说明。该方法包括：
步骤502：在载波组合对应的DCI格式的数量超过数量阈值的情况下，对载波组合对应的DCI格式进行DCI大小对齐操作。
在一些实施例中：
·对于C-RNTI加扰的DCI，数量阈值为3；
·对于所有DCI，数量阈值为4。
终端对同一个被调度的载波组合的多个DCI格式进行DCI大小对齐操作。因为用于调度服务小区4的DCI、或者用于调度服务小区5的DCI、用于调度服务小区4和服务小区5的载波组合的DCI格式属于不同的载波组合，所以，不同的载波组合无需进行DCI大小对齐操作。
具体的，对于被调度的载波组合1：服务小区4，网络侧配置了DCI format 0_0,DCI format 0_1,DCI format 0_2,DCI format 1_0,DCI format 1_1,DCI format 1_2，DCI大小数目超过数量阈值3，则终端进行DCI大小对齐操作，直到DCI大小的数目不大于数量阈值3。
又比如，对于被调度的载波组合6，服务小区4和5的载波组合，网络侧配置了DCI format 0_x和DCI format 1_x，x>2的正整数，由于DCI大小的数目为2，未超过数量阈值3，则终端无需对DCI format 0_x和DCI format 1_x进行DCI大小的对齐操作，无需与其他载波组合进行DCI大小的对齐操作，具体的，无需与载波组合1上的DCI格式进行DCI大小对齐操作。
综上所述，本实施例提供的方法，以载波组合为单位进行DCI大小对齐操作，可以避免在“一调一”和“一调多”的DCI格式之间进行DCI大小对齐操作，简化终端侧的操作。

综上所述，本实施例提供的方法，以载波组合为单位确定终端的PDCCH检测能力，使得PDCCH检测能力能够在载波组合的场景下，实现确定出更为准确的PDCCH检测能力。
本实施例提供的方法，在多个载波组合之间引入调整系数，使得在一个载波组合中包括至少两个载波的情况下，通过该调整系数确定出更为准确的PDCCH检测能力，而无需对同一个服务小区在一个载波组合的累积和计算中不合理地进行累加多次，产生不准确的PDCCH检测能力的判断。
图7示出了本申请一个示例性实施例提供的PDCCH检测方法的流程图。本实施例以该方法应用于网络设备来举例说明。该方法包括：
步骤702：基于载波组合发送PDCCH，载波组合包括一个或多个载波。
网络设备基于一个(被调度的)载波组合发送PDCCH。一个载波组合包括一个或多个载波。多个载波是指至少两个载波。一个被调度的载波组合上的全部或部分频域资源是由一个PDCCH(或一个DCI调度)实现的。
即便在一个载波组合仅包括一个载波的情况下，该载波也是视为一个载波组合来进行处理。
在一些实施例中，(被调度的)载波组合是由高层信令预配置的。
在一些实施例中，属于同一个(被调度的)载波组合的载波配置有相同的子载波间隔。
在一些实施例中，属于同一个(被调度的)载波组合的载波配置有同一个PUCCH组。
在一些实施例中，如图8所示，所述方法还包括：
步骤701：向终端发送与载波组合对应的PDCCH配置。
与载波组合对应的PDCCH配置，配置有PDCCH盲检测的时频区域，映射方式，DCI格式和聚合等级等信息中至少一种。PDCCH配置针对一个载波组合或单个载波组合。针对一个载波组合，PDCCH配置可以配置有一个或多个，在配置有多个PDCCH配置的情况下，多个PDCCH配置与该载波组合的多个BWP一一对应。

·与载波组合对应的PDCCH配置信息(PDCCHConfig)；
·与载波组合对应的控制资源集(ControlResourceSet，或Coreset)；
