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(6 th 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框图。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 Personal 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)或车载终端(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，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、无线局域网(Wireless Local Area Network，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，所述核心网设备可以是位置管理设备，例如，所位置管理功能(LMF、E-SLMC)等。
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控制信道检测方法进行详细地说明。
5G NR系统支持为UE配置一个或多个CC或小区。当UE配置为单载波模式或CA下的自调度模式时，每个CC或小区可配置多个控制资源集(CORESET)以及多个搜索空间(Search Space，SS)，包括公共搜索空间(Common Search Space，CSS)以及UE特定搜索空间(UE-specific Search Space，USS)。网络可以为每个搜索空间集灵活配置盲检数目，CORESET与搜索空间集之间可以灵活关联。UE根据配置的CORESET与SS，通过使用各种无线网络临时标识(Radio Network Tempory Identity，RNTI)盲检测物理下行控制信道(Physical Downlink Control Channel，PDCCH)，解调下行控制信息(Downlink Control Information，DCI)，获取每个小区的调度信息。每个DCI调度一个小区的数据。
如果某些小区的信道质量不够好，或信道阻塞概率较高时，网络可以为 UE配置跨载波调度，即把控制信道配置在其他信道质量较好的小区(例如，主小区，PCell)，来跨载波调度其他小区(例如，辅小区(Secondary Cell，SCell))的数据。调度小区(scheduling cell)与被调度小区(scheduled cell)的子载波带宽(Subcarrier Spacing，SCS)可以相同或不同。调度小区可以是自调度模式，此时该小区只调度自己。如果调度小区被配置了跨载波调度，则它也可以调度一个或多个自己以外的被调度小区。被调度小区没有自己的PDCCH，只能由一个调度小区来调度。现有NR系统中，一个小区只能由一个调度小区来调度(即只能是自调度或被另一个小区调度)，且PCell只能被PCell自己调度。
为了降低UE的实现复杂度，NR系统规定了UE在盲检测一个CC或小区的PDCCH的最大检测能力(或称为最大检测个数)。该能力包含两个部分：在一个时隙(slot)或span内盲检的最大的PDCCH候选数目，以及UE执行盲检所需的最大信道估计数，即不重叠的控制信道元素(Control Channel Element，CCE)的数目。UE的最大检测能力与盲检测的CC或小区的SCS相关，即不同的SCS下一个slot内的处理能力是不同的(见表1-3)。此外，UE还可以上报CA时其支持的最大盲检能力Y。
此外，为了降低UE的实现复杂度，NR系统规定了UE的DCI大小预算(DCI size budget)，即规定了对于每一个被调度小区，UE最多监听的不同大小的DCI格式的数量是4，且USS中的不同大小的DCI格式的最大数量是3。

配置了多个搜索空间集(Search Space set，SS set)时，由于不同SS set的监控空间是独立配置的，因此在不同时间上PDCCH候选/CCEs的数量会变化。因此，允许基站(Base Station，BS)配置每个slot上的PDCCH候选/CCEs总数超过用户能力，这称为超额预定(Overbooking),也可以理解为SS的资源分配顺序或者是映射顺序。
根据配置，每个slot上，根据以下规则映射SS set:
(1)优先映射CSS set(即优先分配盲检资源)；
(2)映射USS(为USS分配盲检资源)，按照SS set标识(Identification，ID)升序进行映射(分配),如果PDCCH候选/CCEs超过用户处理能力的限制,然后不再映射(分配)SS set。
如果没有overbooking功能，SS集的配置将受到worst case(最差情况)的限制(即需要保证每个slot上SS set映射后的PDCCH候选/CCEs总数都不超过用户能力)，因此BS中无法最大限度地发挥用户盲检能力，并导致多用户阻塞。
例如图2所示,以CSS、USS#1、USS#2映射CCE为例，CSS、USS#1、 USS#2的监控时间配置如下，对于slot1、5、9在映射了CSS、USS#1后无法进一步映射USS#2(超过用户能力)。
如果一个UE被配置了多个载波进行CA,且指示了它具有搜索空间共享(search space sharing)能力(例如通过参数earchSpaceSharingCA-UL或searchSpaceSharingCA-DL指示),且在CORESET p中对于一个CCE聚合等级为L的PDCCH候选(candidate)发送一个和服务小区n CI,1相关的DCI格式(format)0_1或一个DCI format 1_1(将该DCI format的大小(size)记做第一size),若假设该PDCCH candidate用于发送一个和服务小区n CI,2相关的DCI format 0_1or a DCI format 1_1(将该DCI format的size记做第二size),该第一size和第二size相等,则该PDCCH candidate可以用于发送一个和服务小区n CI,1相关的DCI format 0_1或一个DCI format 1_1(即配置的一个用于发送调度小区n CI,2的DCI的PDCCH candidate也可以用于发送调度小区n CI,1的DCI,由于第一size和第二size大小一致,这种做法不会增加用户盲检的复杂度,同时又提高了调度灵活性)。
相关技术中提出了多发送接收点/多天线面板(multi-TRP/multi-panel)的场景，多发送接收点(Transmission and Reception Point，TRP)传输可以增加传输的可靠性及吞吐量性能，例如UE可以接收来自于多个TRP的相同数据或不同数据。多TRP传输场景包括：
1)如图3所示，同一TRP内的多天线面板传输，其中，intra-TRP multi-beams为TRP内多波束；
2)如图4所示，多TRP间的多TRP/panel传输，理想回程线路(backhaul)；
3)如图5所示，多TRP间的多TRP/panel传输，非理想回程线路。
一个调度小区可以有多个TRP,不同的TRP可以用于调度相同或者不同的小区，一个被调度小区可以被一个或者多个TPR调度。
对于一个UE,如果该UE可以支持第一组小区(表示为
Figure PCTCN2022084353-appb-000018
)和第二组小 区(表示为
Figure PCTCN2022084353-appb-000019
),第一组小区中,要么每个调度小区的所有下行带宽部分(Downlink Bandwidth Part，DL BWP)上的所有CORESET都没被配置coresetPoolIndex,要么每个调度小区的所有DL BWP上的所有CORESET的coresetPoolIndex被配置为0；第二组小区中,每个调度小区的所有DL BWP上,第一CORESET没被配置coresetPoolIndex或coresetPoolIndex被配置为0,第二CORESET的coresetPoolIndex被配置为1.则该UE确定服务小区数为
Figure PCTCN2022084353-appb-000020
其中R为UE上报的一个值。
出于增强控制信道覆盖考虑，如图6所示，一般将PCell部署在低频段的载波(carrier)。另一方面，低频段carrier的带宽不足，且已经大量部署给其他系列(例如LTE)，其中，Frequency为频率，Coverage为覆盖范围，TDD为时分复用，band为带宽，FDD为频分复用，DSS为动态频谱共享，UL为上行，DL为下行，带宽可以为低/中带宽(low/mid band)，或中/高带宽(Mid/high band)。此时，如图7所示，需要实现通过SCell调度PCell来解决PCell控制信道容量有限的问题，降低控制信道PDCCH开销，其中，PDCCH region为PDCCH区域，DATA region为数据区域。
然而，相关NR系统并不支持使用SCell调度PCell，同时监听来自两个调度小区的PDCCH会大大提高UE的解调和实现的复杂度与功耗，拉高UE的硬件成品，不利于UE的实现。
本申请实施例提供一种控制信道检测方法，如图8所示，所述方法包括：
步骤101：终端获取控制资源组和/或小区组；所述终端配置有第一小区和第二小区，所述小区组包括第一小区，所述第一小区被至少两个小区调度；本实施例中，终端可以获取网络侧设备配置的控制资源组和/或小区组，也可以获取协议规定的控制资源组和/或小区组，还可以获取预配置的控制资源组和/或小区组，还可以自己确定控制资源组和/或小区组,比如根据预设规则确定控制资源组和/或小区组。
步骤102：所述终端基于所述控制资源组和/或小区组，进行控制信道检 测。
一些实施例中，所述终端确定至少一个所述控制资源组对应的控制资源个数或控制资源的预算或最大处理能力，和/或，至少一个所述小区组对应的控制资源个数或控制资源的预算或最大处理能力；
其中，所述控制资源为终端需要检测的控制资源。
在本申请实施例中，终端至少配置有第一小区和第二小区，所述第一小区被至少两个小区调度，终端获取控制资源组和/或小区组，并基于所述控制资源组和/或小区组，进行控制信道检测，比如确定至少一个所述控制资源组对应的控制资源个数或控制资源的预算或最大处理能力，和/或，至少一个所述小区组对应的控制资源个数或控制资源的预算或最大处理能力。本实施例的技术方案能够降低解调以及实现的复杂度,保证终端和网络侧设备理解一致，支持一个小区被多个小区调度。
本实施例中，Cell-1(第一小区)可以被不少于两个cell上的控制资源调度，例如cell-1可以是Pcell(主小区)或PScell(主辅小区),可以调度cell-1的不少于两个小区可能包含cell-1,也可以不包含cell-1。Cell-2(第二小区)可以是用于调度Pcell或PScell的Scell。
本实施例也可以用于多传输面板(multiple Transmission and Reception Panel，M-TRP)的场景，即发明中的cell-1、cell-2也可以是同一个cell的TRP-1与TRP-2，UE监听对应不同的TRP(即配置不同的CORESET池索引(pool index))的SS的PDCCH。
一些实施例中，所述至少两个小区包括所述第二小区。
本实施例中，UE至少被配置了cell-1与cell-2，其中，cell-1可以进行自调度，同时cell-2也可以调度cell-1。UE监听cell-1自调度的SS(以下称为SE-SS)，以及cell-2上调度cell-1的SS(以下称为CR-SS)，以获取调度cell-1的调度指令(例如DCI)。
同时，UE还可以监听cell-2上的其他SS(以下称为O-SS)，以获取cell-2 上调度cell-2和/或其他cell(比如cell-3)的调度DCI。
其中，上述SE-SS，CR-SS或O-SS都可以是CSS或USS。
一种特殊的场景是，cell-1上没有自调度，cell-2上配置了一个DCI-J同时或联合调度cell-1与cell-2的数据，此时，cell-2上还可以配置DCI-2单独调度cell-1。
一优选实施例中，第一小区为主小区或主辅小区，所述第二小区为辅小区。即，cell-1为Pcell或PScell,cell-2为调度cell-1的一个Scell。
一些实施例中，物理信道的起点时间和/或结束时间采用物理时间和/或绝对时间。
可选地,在比较两个物理信道的起点时间或者终点时间时,采用的是基于物理时间和/或绝对时间的起点时间或者终点时间进行比较。例如对于给定的被调度小区中的任意两个混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)进程ID，如果UE收到一个结束于符号i的PDCCH且该PDCCH调度了从符号j开始的第一物理下行共享信道(Physical downlink shared channel，PDSCH)，则UE不期望被一个终点时间晚于符号i的PDCCH调度去接收一个起点时间早于第一PDSCH终点时间的PDSCH。在该比较中,提及的起点时间和终点时间为采用物理时间和/或绝对时间确定的起点时间和终点时间。
可选地,所述物理时间和/或绝对时间是基于预设定时确定的时间。在一种实施例中,预设定时为下行定时或上行定时。更具体地,在一种实施例中,预设定时为某个小区或者载波的下行定时或上行定时,例如最大或最小SCS的小区的下行定时或上行定时,或者例如第一小区或Pcell或PScell的下行定时或上行定时,或者例如可以调度Pcell或PScell的Scell的下行定时或上行定时,或者例如第二小区的下行定时或上行定时。在一种实施例中,预设定时为物理信道所在小区的下行定时或上行定时。优选地,该预设定时为下行定时。
一些实施例中，所述控制资源包括以下至少一项：
用于所述第二小区调度所述第一小区的控制资源；
所述第二小区自调度的控制资源；
所述第一小区自调度的控制资源；
所述第二小区用于调度第三小区的控制资源，所述第三小区可以是除所述第一小区和所述第二小区之外的小区；
第四小区的控制资源，所述第四小区为除所述第一小区和所述第二小区之外的小区。
在一些实施例中,所述终端确定第一小区和第二小区对应的联合信道监控预算，第一小区和第二小区对应的联合信道监控预算可以为第一小区自调度的控制资源对应的控制资源个数和第二小区调度第一小区的控制资源对应的控制资源个数的加权和,进一步的,如果有多个加权和,则第一小区和第二小区对应的联合信道监控预算为这些加权和中的最大值或者最小值或者加权值.或者,进一步的,第一小区和第二小区对应的联合信道监控预算可以为第一小区自调度的控制资源对应的最大资源个数和第二小区调度第一小区的控制资源对应的最大资源个数的加权和.进一步可选地,上述第一小区自调度的控制资源和第二小区调度第一小区的控制资源处于相同的时间单元。
比如第一小区和第二小区对应的联合信道监控预算为第一小区的CSS中最大控制资源个数和第二小区上用于调度第一小区的最大控制资源个数的和,或，为一个slot或span上第一小区CSS中最大控制资源个数和第二小区上用于调度第一小区的控制资源个数的和中的最大值。

所述第一控制资源组包括被至少两个小区调度的被调度小区对应的控制资源；所述第二控制资源组包括仅被一个小区调度的被调度小区对应的控制资源。
一些实施例中，若所述第一控制资源组包括所述第二小区用于调度所述第一小区的控制资源；所述第二控制资源组包括所述第二小区用于调度除所述第一小区之外其他小区的控制资源，则所述第二控制资源组包括所述第一小区和第二小区之外第五小区的控制资源。
