5G NR系统支持载波聚合(carrier aggregation，CA)，可以为终端设备配置并激活多个载波(component carrier，CC)或小区，且支持载CA下跨载波调度。此外，NR也支持多传输面板(multiple Transmission and Reception Panel，M-TRP)的场景，终端设备可以被多个TRP进行数据调度与收发。但Release-15NR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只能被主小区(Primary Cell，PCell)自己调度。
出于增强控制信道覆盖考虑，一般将PCell部署在低频段的载波carrier。由于低频段carrier的带宽不足，且已经大量部署给其他系列(例如LTE)，PCell控制信道容量有限，相关技术中的这种调度方式难以解决PCell控制信道容量有限的问题。

如图1所示，本发明的一个实施例提供一种搜索空间的监听方法100，该方法可以由终端设备执行，换言之，该方法可以由安装在终端设备的软件或硬件来执行，该方法100包括如下步骤：
S102：获取调度配置信息。
本发明实施例中，终端设备可以配置多个传输对象，这多个传输对象可以是多个小区；或者是多传输点(multiple Transmission and Reception Point，M-TRP，或称多发送接收点)， 即传输对象的搜索空间关联特定的CORESET或CORESET pool。
可选地，终端设备获取(例如接收)到的调度配置信息可以用于配置如下至少之一：上述多个传输对象配置；监听的搜索空间(Search Space，SS)；调度的下行控制信息(Downlink Control Information，DCI)格式等。上述调度配置信息可以用于配置上述多个传输对象间的调度关系。
S104：根据调度配置信息监听SS，该SS包括至少两个传输对象对一个传输对象(还可以称作是被调度的传输对象)进行调度的SS。
可选地，该SS包括至少两个小区(可以称作是调度小区)对一个小区(可以称作是被调度小区)进行调度的SS；或者是，该SS包括至少两个TRP(可以称作是调度TRP)对一个TRP(可以称作是被调度TRP)进行调度的SS。
可选地，上述多个传输对象至少包括第一传输对象和第二传输对象，终端设备监听的SS包括如下至少之一：
1)多个传输对象中第二传输对象之外的传输对象(例如，第一对象，第三传输对象，第四传输对象等)调度第一传输对象的第一SS；其中，第一传输对象调度第一传输对象的情形下，第一SS可以称作是第一传输对象自调度的SS。
2)第二传输对象调度第一传输对象的第二SS。
3)第二传输对象自调度的第三SS。
在一个例子中，终端设备监听的SS包括第一传输对象自调度的第一SS以及第二传输对象调度第一传输对象的第二SS，当然还可以包括第二传输对象自调度的第三SS。
在另一个例子中，终端设备监听的SS包括第二传输对象、第三传输对象等调度第一传输对象的第二SS。
可选地，作为一个实施例，在S104中提到的监听SS可以是在第一特定时间内，满足如下至少之一：
1)监听上述第一SS的处理能力不超过单个所述传输对象的最大处理能力；
2)监听上述第二SS和第三SS的总处理能力不超过单个所述传输对象的最大处理能力；
3)监听上述第二SS和第三SS的总处理能力不超过L乘以单个所述传输对象的最大处理能力，所述L为正数。
可选地，L小于或等于所述第二传输对象调度的传输对象的数量。
可选地，所述L是预定义的；或所述L与所述终端设备上报的最大处理能力M相关。
本发明实施例提供的搜索空间的监听方法，终端设备配置有多个传输对象(例如，多个小区或多个TRP)，可以支持一个小区(或TRP)自调度的同时，被另一个小区(或 TRP)调度，例如，支持PCell自调度的同时支持通过SCell调度PCell，解决(PCell)控制信道容量有限的问题，提升通信效率。
在一个具体的实施例中，实施例100中提到的终端设备配置了cell-1与cell-2。其中，cell-1是自调度，同时cell-2也可以调度cell-1。终端设备监听cell-1自调度的SS(以下称为SE-SS)，以及cell-2调度cell-1的SS(以下称为CR-SS)，以获取调度cell-1的调度指令DCI。
同时，终端设备还可以监听cell-2上的其他SS(以下称为O-SS)，以获取调度cell-2的调度DCI。
可选地，该实施例中上述提到的SE-SS，CR-SS或O-SS都可以是公共搜索空间(common search space，CSS)或终端设备的特定搜索空间(UE-specific search space，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/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。
上述实施例中，针对终端设备监听SS的处理能力，以下将分a、b、c三个方案进行说明。
a)可选地，在特定时间内(例如，一个时隙内)，终端设备监听cell-1的PDCCH(例如，SE-SS)的处理能力不超过终端设备单个小区的最大处理能力。即，终端设备监听的PDCCH候选数不超过单个小区的最大的PDCCH候选数目；终端设备监听的不重叠控制信道元素(Control Channel Element，CCE)的数目不超过单个小区的最大的不重叠CCE数目；终端设备监听的不同大小DCI格式的最大数量不超过单个小区的DCI格式的数量(DCI size budget)，后文各个实施例与该实施例类同。
该实施例中提到的处理能力与调度小区和/或被调度小区的参数(例如，numerology/SCS)有关，例如，根据cell-1或cell-2的SCS确定，或根据其中最大或最小的SCS确定，等等。
该实施例中提到的“终端设备监听……的处理能力”，表示根据网络设备的配置参数，终端设备监听PDCCH所需的处理能力，或者终端设备通过其他方式获取(例如，自己确定)的监听PDCCH所需的处理能力，后文各个实施例与该实施例类同。
b)可选地，在特定时间内，终端设备监听的cell-2的PDCCH(例如CR-SS与O-SS)的总处理能力不超过终端设备单个小区的最大处理能力。(见后文本发明实施例一)
该实施例中，CR-SS与O-SS可以是不同的SS，或者，CR-SS与O-SS可以是相同的SS，此时SS里面不同的PDCCH候选对应不同被调度小区的DCI，根据小区ID或CIF进行标示。
该实施例中的处理能力与调度小区和/或被调度小区的参数(例如，numerology/SCS) 有关，例如，根据cell-1或cell-2的SCS确定，或根据其中最大或最小的SCS确定，等等。
该方案b)实质是将cell-2的处理能力分配了一部分给cell-1，好处是实现简单，但也可能导致cell-2的可监听候选数量减少，而cell-1的监听能力却浪费了，有可能导致调度灵活性下降。
该方案b)还适用于当cell-1上不配置自调度，只通过cell-2的跨载波调度DCI或联合/多小区调度DCI调度cell-1的场景。
c)可选地，终端设备监听的CR-SS与O-SS的总处理能力不超过(N×终端设备单个小区的最大处理能力)(见本发明后续的实施例二)。
可选地，N≤cell-2调度的小区的数量，例如，在cell-2调度cell-1与cell-2时，N＝2或N＝1.5。
上述方案b)是N＝1的特例。
可选地，N可以是协议预定义的，或N可以与终端设备上报的处理能力M有关(例如，N≤M)。
该方案c)的好处是可以保持cell-2的调度灵活性，但要求cell-2有更大的处理能力，可能更高的硬件成本与能耗。
需要说明的是，上述a、b、c三个方案中提到的特定时间可以是同一个特定时间，例如同一个时隙；也可以是不同的特定时间，例如，方案a、b、c分别是在不同的时隙内监听SS。
可选地，作为一个实施例，实施例100中提到的至少两个传输对象中的第i个传输对象A i分配有处理能力阈值X i，所述X i不超过单个所述传输对象的最大处理能力；其中，在第二特定时间内，监听所述A i对一个所述传输对象进行调度的SS的处理能力不超过所述X i。
该实施例还可以包括自调度的场景，即某一个传输对象Ai调度的传输对象是其本身。
可选地，至少两个所述X i满足如下关系：
Figure PCTCN2021074919-appb-000001
其中，所述N是所述至少两个传输对象的数量，N大于或等于2；
所述R是根据所述至少两个传输对象的参数中的至少一个确定的最大处理能力；或
所述R是根据被调度的一个所述传输对象的参数确定的最大处理能力；或
所述R是所述终端设备上报的最大处理能力。
可选地，至少两个所述X i满足如下关系：
Figure PCTCN2021074919-appb-000002
其中，所述N是所述至少两个传输对象的数量，N大于或等于2；
P i为根据所述A i的参数确定的最大处理能力。
为详细说明，以下将结合一个具体的实施例进行说明。还以之前的例子为例：即终端设备配置了cell-1与cell-2。其中，cell-1是自调度，同时cell-2也可以调度cell-1。终端设备监听cell-1自调度的SS(以下称为SE-SS)，以及cell-2调度cell-1的SS(以下称为CR-SS)，以获取调度cell-1的调度指令DCI。同时，终端设备还可以监听cell-2上的其他SS(以下称为O-SS)，以获取调度cell-2的调度DCI。
可选地，在特定时间内，对于被调度小区cell-1：
终端设备监听SE-SS的处理能力不超过一个阈值X 1，且X 1不大于单个小区的最大处理能力；终端设备监听CR-SS的处理能力不超过一个阈值X 2，且X 2不大于单个小区的最大处理能力。
该实施例中监听SE-SS的特定时间和监听CR-SS的特定时间可以是同一个特定时间，例如同一个时隙；也可以是不同的特定时间，例如，分别是在不同的时隙内监听SE-SS与CR-SS。
可选地，该阈值X 1阈值X 2与调度小区和/或被调度小区的参数(例如，numerology/SCS)有关，例如，根据cell-1或cell-2的SCS确定，或根据其中最大或最小的SCS确定，等等。
优选的，阈值X 1阈值X 2满足特定关系：
X 1+X 2＝R，其中R为根据cell-1或cell-2的参数(SCS)确定的最大处理能力，或R为用户上报的。
例如，以最大PDCCH候选为例，假设cell-1与cell-2的SCS不相同(cell-1：μ＝0，cell-2：μ＝1)，则X 1+X 2＝44(根据cell-1)或X 1+X 2＝36(根据cell-2)。
或者，X 1/P 1+X 2/P 2＝1，其中，P 1为根据SE-SS的小区(即cell-1)确定的最大处理能力，P 2为根据CR-SS的小区(即cell-2)确定的最大处理能力(见本发明后续实施例三)。
例如，以最大PDCCH候选为例，假设cell-1与cell-2的SCS相同(μ＝0)，则可能的阈值为X 1＝30，X 2＝14，满足30/44+14/44＝1。
假设cell-1与cell-2的SCS不相同(cell-1：μ＝0，cell-2：μ＝1)则可能的阈值为X 1＝22，X 2＝18，满足X 1/P 1+X 2/P 2＝22/44+18/36＝1。
该方案的实质是将部分cell-1的硬件处理能力分配给了cell-2进行PDCCH监听，好处是保持了较高的调度灵活性，且不会提高硬件成本与能耗。
优选的，阈值X 1阈值X 2是一个量化的整数值，即，X 1和X 2的候选值是几个正整数，例如，以最大PDCCH候选为例，X 1不是0，…，44之间的任意整数，而是以K为步长(例如K＝4)的等差序列0，4，8，…，40，44。这样可以简化终端设备的实现复杂度。
需要说明的是，该实施例的描述以两个cell为例说明，但本方案适用于两个以上cell的场景，上述阈值X i的数量还可以更多，例如，X 3，X 4等等。
可选地，X 1和X 2可以是协议预定义的，或网络配置的，或X 1和X 2可以与终端设备上报的能力有关(终端设备上报X 1和X 2，或X 1和X 2根据终端设备上报的一个或多个能力值计算获得)，终端设备可以只上报X 1或X 2中的一个值，另一个值通过上述需满足的特定关系推算。
可选地，作为一个实施例，实施例100中提到的至少两个传输对象中的第i个传输对象A i分配有处理能力G i，所述G i不超过单个所述传输对象的最大处理能力；其中，在第三特定时间内，监听所述A i对一个所述传输对象进行调度的SS的处理能力为所述G i。
可选地，至少两个所述G i满足如下关系：
Figure PCTCN2021074919-appb-000003
其中，所述N是所述至少两个传输对象的数量，N大于或等于2；
所述S是根据所述至少两个传输对象的参数中的至少一个确定的最大处理能力；或
所述S是根据被调度的一个所述传输对象的参数确定的最大处理能力。
可选地，至少两个所述G i满足如下关系：
Figure PCTCN2021074919-appb-000004
其中，所述N是所述至少两个传输对象的数量，N大于或等于2；
所述Q i为根据所述A i的参数确定的最大处理能力。
为详细说明，以下将结合一个具体的实施例进行说明。还以之前的例子为例：即终端设备配置了cell-1与cell-2。其中，cell-1是自调度，同时cell-2也可以调度cell-1。终端设备监听cell-1自调度的SS(以下称为SE-SS)，以及cell-2调度cell-1的SS(以下称为CR-SS)，以获取调度cell-1的调度指令DCI。同时，终端设备还可以监听cell-2上的其他SS(以下称为O-SS)，以获取调度cell-2的调度DCI。
在特定时间内，对于被调度小区cell-1：终端设备配置监听SE-SS所需的处理能力为G 1；终端设备配置监听CR-SS所需的处理能力为G 2，G 1和G 2满足特定关系：
G 1+G 2≤S，其中S为根据cell-1或cell-2的参数(SCS)确定的最大处理能力；
或者，G 1/Q 1+G 2/Q 2≤1，其中，Q 1为根据SE-SS的小区(即cell-1)确定的最大处理能力，Q 2为根据CR-SS的小区(即cell-2)确定的最大处理能力(见本发明实施例四)。
该实施例中监听SE-SS的特定时间和监听CR-SS的特定时间可以是同一个特定时间，例如同一个时隙；也可以是不同的特定时间，例如，分别是在不同的时隙内监听SE-SS与CR-SS。
可选地，G 1和G 2与调度小区和/或被调度小区的参数(例如，numerology/SCS)有关。
优选的，G 1和G 2是一个量化的整数值，参见前文实施例。
可选地，作为一个实施例，实施例100中在第四特定时间内，针对所述至少两个传输对象中的第i个传输对象A i，监听所述A i对一个所述传输对象进行调度的SS的处理能力不超过所述A i的最大处理能力。
为详细说明，以下将结合一个具体的实施例进行说明。还以之前的例子为例：即终端设备配置了cell-1与cell-2。其中，cell-1是自调度，同时cell-2也可以调度cell-1。终端设备监听cell-1自调度的SS(以下称为SE-SS)，以及cell-2调度cell-1的SS(以下称为CR-SS)，以获取调度cell-1的调度指令DCI。同时，终端设备还可以监听cell-2上的其他SS(以下称为O-SS)，以获取调度cell-2的调度DCI。
在特定时间内：
对于被调度小区cell-1，终端设备监听的总处理能力(包括SE-SS与CR-SS)不超过终端设备单个被调度小区cell-1的最大处理能力；
对于调度小区cell-2，终端设备监听的CR-SS与O-SS的总处理能力不超过终端设备单个调度小区cell-2的最大处理能力。
该实施例中监听SE-SS与CR-SS的特定时间，和监听CR-SS与O-SS的特定时间可以是同一个特定时间，例如同一个时隙；也可以是不同的特定时间，例如，分别是在不同的时隙内监听SE-SS与CR-SS；CR-SS与O-SS。
该实施例中，网络设备可以灵活选择一个SS进行调度，只要不超过上述最大处理能力。
该实施例实质是把硬件处理能力动态分配用于cell-1与cell-2的PDCCH监听，可以获得最大调度灵活性。
可选地，作为一个实施例，前文各个实施例中提到的监听SS的处理能力与如下至少之一相关：特定的DCI格式或大小；特定SS；所述传输对象的参数；配置的所述多个传输对象的数量；控制资源集CORESET的标识。
也即，在特定时间内，终端设备分配的监听能力与特定DCI格式或大小、特定搜索空间、小区参数(numerology/SCS)、调度的小区数量、CORESET的标识(CORESET ID或pool ID等)中的至少一个有关。
该实施例中，用于监听DCI的监听能力可以是共享调度小区或任一个或多个被调度小区的监听能力；或者，该部分能力是从调度小区与被调度小区的监听能力中各分配一部分组成(见本发明后文实施例六)。
可选地，作为一个实施例，前文各个实施例中提到的特定时间，以及具体的第一特定 时间、第二特定时间、第三特定时间和第四特定时间的至少之一包括下述之一：

可选地，作为一个实施例，实施例100获取调度配置信息之前，所述方法还包括：发送终端能力，所述终端能力包括以下至少之一：
是否支持监听至少两个所述传输对象对一个所述传输对象进行调度；
监听至少两个所述传输对象的最大处理能力；
可调度的PDSCH或PUSCH的最早起始位置；
特定时间间隔的长度；
监听定时器的长度。
可选地，在前文各个实施例中，网络设备可以为终端设备配置上述cell-1，cell-2配置，监听的SS(包括CR-SS，SE-SS，O-SS等)，以及调度的DCI格式等等。可选地，配置需要满足上述终端设备监听的限制；或网络设备接收终端设备上报的能力，根据终端设备能力进行配置。
为详细说明本发明实施例提供的搜索空间的监听方法，以下将结合几个具体的实施例进行说明。
实施例一：
网络设备为终端设备配置了Pcell与Scell，且Scell调度Pcell，Pcell与Scell的SCS都是15kHz(即μ＝0)。
网络设备配置了Pcell自调度的SE-SS的PDCCH候选数A＝40，Scell自调度的O-SS的PDCCH候选数B＝15，Scell调度Pcell的CR-SS的PDCCH候选数C＝20，即分配了Scell的部分处理能力用于调度Pcell。
终端设备同时监听上述SS，其中A<44，B+C＝35<44，均不超过终端设备单个slot内的最大处理能力。
实施例二：
网络设备为终端设备配置了Pcell与Scell，且Scell调度Pcell，Pcell与Scell的SCS都是15kHz(即μ＝0)。
终端设备上报其支持的跨载波调度的能力N＝1.5。
网络设备配置了Pcell自调度的SE-SS的PDCCH候选数A＝40，Scell自调度的O-SS的PDCCH候选数B＝40，Scell调度Pcell的CR-SS的PDCCH候选数C＝20，即分配了Scell的部分处理能力用于调度Pcell。
终端设备同时监听上述SS，其中A<44。B+C＝60，60>44但60<44×N＝66，因此不超过终端设备单个slot内的最大处理能力。
实施例三：
网络设备为终端设备配置了Pcell与Scell，且Scell调度Pcell，Pcell的SCS是15kHz(即μ＝0)，Scell的SCS是30kHz(即μ＝1)。
终端设备上报对于被调度小区的阈值为X 1＝22，网络设备计算X 2＝18满足22/44+18/36＝1。
网络设备配置了Pcell自调度的SE-SS的PDCCH候选数A＝20，Scell自调度的O-SS的PDCCH候选数B＝20，Scell调度Pcell的CR-SS的PDCCH候选数C＝10，即分配了Scell的部分处理能力用于调度Pcell。
终端设备同时监听上述SS，其中A<X 1＝22，C<X 2＝18，B<36，因此不超过终端设备单个slot内的最大处理能力。
实施例四：
网络设备为终端设备配置了Pcell与Scell，且Scell调度Pcell，Pcell的SCS是15kHz(即μ＝0)，Scell的SCS是30kHz(即μ＝1)。
终端设备上报对于被调度小区的阈值为X 1＝22，网络设备计算X 2＝18满足22/44+18/36＝1。
网络设备配置了Pcell自调度的SE-SS的PDCCH候选数A＝20，Scell自调度的O-SS的PDCCH候选数B＝20，Scell调度Pcell的CR-SS的PDCCH候选数C＝10，即分配了Scell的部分处理能力用于调度Pcell。
终端设备同时监听上述SS，其中，A/44+C/36＝20/44+10/36<1，B<36，因此均不超过终端设备单个slot内的最大处理能力。
实施例五：
网络设备为终端设备配置了Pcell与Scell，且Scell调度Pcell，Pcell与Scell的SCS都是15kHz(即μ＝0)。
网络设备配置了scaling factor N，指示如果分配小区间的最大处理能力。N＝0.5，表示Pcell分配一半的能力用于自调度，一半的能力用于Scell调动Pcell。
终端设备根据配置的N以及cell的SCS，确定被调度的Pcell的监听PDCCH能力：
Pcell自调度的SE-SS的最大PDCCH候选数＝44×N＝24，Scell调度Pcell的CR-SS的最大PDCCH候选数＝44×N＝22，
Pcell自调度的DCI size budget＝4×N＝2，Scell调度Pcell的DCI size budget＝4×N＝2，即自调度监听的不同DCI格式数为2，Scell调度Pcell的不同DCI格式数为2。
实施例六：
网络设备为终端设备配置了Pcell与Scell，Pcell与Scell的SCS都是15kHz(即μ＝0)，且Pcell配置了DCI-J用于同时调度Pcell与Scell的数据。
终端设备配置部分监听能力用于监听DCI-J。
该部分监听能力可以是共享Pcell或Scell的监听能力，或者，该部分能力是从Pcell与Scell的监听能力中各分配一部分。
按照一定比例(scaling factor)，终端设备可以上报分配比例给网络设备，或，按照一定规则，例如，DCI-J只调度PDSCH，Scell自调度PUSCH，或通过Pcell跨载波调度Scell的PUSCH。
此时，将Scell的PDSCH的调度能力分配用于监听DCI-J。
实施例七
网络设备为终端设备配置了Pcell上监听TRP-1(关联CORESET pool ID＝0)与TRP-2(关联CORESET pool ID＝1)，每个TRP自调度，且TRP-1还可以调度TRP-2，Pcell的SCS是15kHz(即μ＝0)。
其中，SS-0与SS-1关联CORESET pool ID-0，SS-2关联CORESET pool ID-1，SS-0调度TRP-0，且SS-1与SS-2可以调度TRP-1。
终端设备上报其支持的跨TRP调度的能力L＝1，以及两个TRP的总调度能力R＝1.5，即最大PDCCH候选＝44*R＝66；
网络设备配置了SS-0的PDCCH候选数A＝20，SS-2的PDCCH候选数B＝20，SS-1的PDCCH候选数C＝10，即分配了TRP-1的部分处理能力用于监听对TPR-2的调度。
终端设备同时监听上述SS，其中A+B+C<66，A+C＝30<44，均不超过终端设备的最大处理能力。
本发明上述各个实施例可应用于CA或M-TRP下的搜索空间监听方法，可以支持一个小区(或TRP)自调度的同时，被另一个小区(或TRP)调度，例如监听PCell与SCell对PCell的调度DCI，在两个调度小区间分配终端设备盲检测的最大PDCCH候选数，最大不重叠CCE数，DCI size budget等等，从而可以简化终端设备实现，降低功耗。
需要说明是的是，以上各个实施例的描述多是以两个cell为例说明，但本方案适用于两个以上cell的场景；
以上各个实施例的描述以cell-2只调度cell-1与cell-2自己为例说明，但本方案同样适用于cell-2调度两个以上cell的场景。
上述方案中，cell-2调度cell-1的DCI可以是单独调度一个小区的DCI，也可以是同时/联合调度多个小区的DCI。例如，cell-2调度cell-1时，可以是一个特殊的DCI同时调度两个cell的数据。
本发明上述各个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，终端设备监听对应不同的TRP(即配置不同的CORESET pool index)的SS的PDCCH。
需要说明的是，本说明书上述各个实施例均是以至少两个小区对一个小区进行调度为例进行说明，实际上，上述各个实施例同样适用于至少两个TRP对一个TRP进行调度的场景，也即可以将前文各个实施例中的小区替换为TRP。
