传输方法、装置、通信设备及终端
交叉引用
本发明要求在2020年08月28日提交中国专利局、申请号为202010889951.4、发明名称为“传输方法、装置、通信设备及终端”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本申请属于无线通信技术领域，具体涉及一种传输方法、装置、通信设备及终端。
背景技术
在相关技术中，在某些情况下，某个上下行信道或上下行信号的空间信息需要根据参考资源的空间信息确定。主要包括在未配置、激活或指示，以及其他无法确定接收下行信道、下行信号的空间信息时，接收这些下行信道、下行信号使用的空间信息，其中下行信道包括物理下行共享信息(Physical downlink shared channel，PDSCH)或跨成员载波(Component Carrier，CC)调度的PDSCH等，下行信号包括非周期信道状态信息参考信号(Aperiodic Channel State Information Reference Signal，AP-CSI-RS)等；在未配置、激活或指示，以及其他无法确定发送上行信道、上行信号的空间信息时，发送这些上行信道、上行信号使用的空间信息，其中上行信道包括物理上行共享信道(Physical Uplink Shared Channel，PUSCH)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)等，上行信号包括探测参考信号(Sounding Reference Signal，SRS)等。上述情况下接收下行信道、下行信号的空间信 息，发送上行信道、上行信号的空间信息通常对应参考资源的空间信息，其中参考资源可以为控制资源集(Control resource set，CORESET)、调度该下行信道/信号、上行信道/信号的物理下行控制信道(Physical downlink control channel，PDCCH)、或其他信道/信号。
例如，当一个终端(User Equipment，UE，也称为用户设备)在一个CORESET配置的高层参数tci-PresentInDCI被设置为“enabled”时，则UE认为该CORESET上传输的PDCCH中的下行控制信息(Downlink Control Information，DCI)格式1_1(DCI format 1_1)或DCI格式1_2(DCI Format1_2)包括传输配置指示(Transmission Configuration Indication，TCI)域，该域用于指示包括空间接收波束的信息，例如，TCI状态(TCI state)。UE只有检测到DCI后，才能从中正确解读TCI状态，确定接收该PDCCH调度的PDSCH使用的接收波束。UE检测DCI以及根据TCI指示切换波束需要一定时间，如果DCI格式1_1指示调度PDSCH的时间偏移，即DCI所在PDCCH的最后一个符号与其调度的单时隙(single-slot)或多时隙(multi-slot)PDSCH的第一个符号之间的符号间隔，大于等于门限值timeDurationForQCL，则UE可以按照该DCI中TCI域指示的接收波束接收服务小区的PDSCH，即可以认为单时隙或多时隙(multi-slot)PDSCH的解调参考信号(Demodulation Reference Signal，DMRS)端口与TCI域指示的TCI状态的参考信号(Reference Signal，RS)是准共址(Quasi Co-Located，QCL)的。而当在一个CORESET上配置的高层参数tci-PresentInDCI被设置为“enabled”，或未配置高层参数tci-PresentInDCI时，如果媒体接入控制层(Medium Access Control，MAC)控制单元(Control Element，CE)激活的所有TCI码点均映射为一个TCI状态，且上述时间偏移小于timeDurationForQCL，此时UE尚未检测完毕DCI或完成接收波束切换操作，则UE可以使用默认接收波束缓存这些符号上的接收信号，以便成功检测到DCI后解调调度的PDSCH。UE可以使用默认接收波束接收PDSCH，即UE 可以认为服务小区的PDSCH的DMRS端口与用于CORESET内的PDCCH QCL指示的QCL参数中的RS是QCL的，其中，该CORESET是最近时隙内UE监测的服务小区激活带宽部分(Bandwidth Part，BWP)上的一个或多个CORESET中关联到监测搜索空间(Search Space，SS)的具有最小CORESET ID的CORESET。
但在某些场景下，某个上下行信道或上下行信号的参考资源可能对应多个空间信息，在这种情况下，通信设备无法确定上下行信道或上下行信号的空间信息。例如，在多传输接收节点(Transmission and Reception Point，TRP)场景下作为控制信道的一种可靠性增强实现方式，PDCCH由多个TRP发送以减小波束链路失败的概率，在这种情况下，PDCCH可能对应多个TCI状态或QCL，如果UE认为服务小区的PDSCH的DMRS端口与用于CORESET内的PDCCH QCL指示的QCL参数中的RS是QCL的，则由于PDCCH对应多个不同的TCI状态或QCL，则UE无法确定接收PDSCH的空间信息。

图2示出本申请实施例中的传输方法的一种流程示意图，该方法200可以由通信设备执行。换言之，所述方法可以由安装在通信设备上的软件或硬件来执行。如图2所示，该方法可以包括以下步骤。
S210，在目标对象的第一空间信息根据参考资源对应的第二空间信息确定的情况下，通信设备确定所述目标对象的第一空间信息与目标空间信息对应；其中，所述参考资源对应多个第二空间信息，所述目标空间信息为多个所述第二空间信息中的一个或多个。
在本申请实施例中，目标对象的第一空间信息根据参考资源对应的第二空间信息确定是指目标对象的第一空间信息不能采用下行控制信息中指示的空间信息，或者，下行控制信息中未指示目标对象的第一空间信息。例如，当在一个CORESET上配置的高层参数tci-PresentInDCI被设置为“enabled”，该CORESET上传输的PDCCH中的DCI采用DCI格式1_1(DCI format 1_1) 或DCI格式1_2(DCI Format 1_2)，该DCI中包括TCI域，但该DCI所在PDCCH的最后一个符号与其调度的单时隙或多时隙PDSCH的第一个符号之间的符号间隔小于第一预设门限(timeDurationForQCL)，则目标对象(此时为PDSCH)的第一空间信息根据参考资源的第二空间信息确定，其中，参考资源可以为最近的时间单元(例如，时隙、子时隙、或一个时隙或多个时隙中多个OFDM符号(例如SPAN))的检测搜索空间(monitored search space)所关联的CORESET中具有最小ID的CORESET。
在本申请实施例中，所述参考资源对应多个第二空间信息包括：目标对象对应的参考资源为一个，该参考资源对应多个第二空间信息；或者，目标对象对应的参考资源为多个，即参考资源包括多个子参考资源，每个子参考资源对应一个或多个第二空间信息。
例如，以参考资源为PDCCH或搜索空间为例，在实际应用中，PDCCH可以采用以下方式(1)和(2)中的之一发送。
(1)一个PDCCH或搜索空间的时频资源基于某种资源粒度按照一定的规则分别对应不同第二空间信息，以频分复用(Frequency Division Multiplex，FDM)或者以时分复用(Time Division Multiple，TDM)方式发送。其中，资源粒度可以是控制信道元素(CCE，Control-channel element)、资源元素组(REG，Resource Element Group)、REG束(REG bundle)、预编码颗粒度(precoder Granularity)、PDCCH候选(candidate)、搜索空间(search space)检测机会等。
(2)一个PDCCH的多次传输中对应的不同第二空间信息，以空分复用(Spatial Division Multiple，SDM)、FDM、TDM或者它们之间的组合方式发送。
因此，在一个可能的实现方式中，PDCCH对应多个第二空间信息包括以下(1)至(4)中的至少一项。
(1)一个PDCCH属于一个搜索空间或PDCCH的多次传输属于一个搜 索空间，并且该搜索空间关联一个CORESET，其中该CORESET对应至少两个第二空间信息。
(2)一个PDCCH属于一个搜索空间或PDCCH的多次传输属于一个搜索空间，并且该搜索空间关联至少两个CORESET，其中每个CORESET对应一个第二空间信息。
(3)PDCCH的多次传输属于不同的搜索空间，并且每个搜索空间都关联同一个CORESET，其中该CORESET对应至少两个第二空间信息。
(4)PDCCH的多次传输属于不同的搜索空间，并且每个搜索空间分别关联一个CORESET，其中每个CORESET对应一个第二空间信息。
在另一个可能的实现方式中，终端被配置为多个搜索空间用于发送同一PDCCH，所述多个搜索空间对应多个第二空间信息包括以下(1)和(2)中的至少一项。
(1)所述多个搜索空间关联至少两个CORESET，其中每个CORESET对应一个第二空间信息。
(2)所述多个搜索空间关联同一个CORESET，其中该CORESET对应至少两个第二空间信息，每个搜索空间对应该CORESET的一个第二空间信息。
上述PDCCH、搜索空间或CORESET对应的至少两个第二空间信息可以属于同一TRP。在多TRP(Multiple TRP，MTRP)场景下，上述PDCCH、搜索空间或CORESET对应的至少两个第二空间信息可以分别属于不同TRP。
在本申请实施例中，目标空间信息可以为多个第二空间信息中的一个或多个，具体为一个还是多个，可以根据预先设置、约定或实际调度来确定。例如，调度下行信道/下行信号或上行信道/上行信号的DCI中指示的空间信息为多个，则目标空间信息可以为多个第二空间信息中的多个，或者，当配置和/或激活参考资源的第二空间信息为多个时，则目标空间信息可以为多个第二空间信息中的多个。
在一个可能的实现方式中，目标空间信息可以为多个第二空间信息中信号强度最强的一个或多个第二空间信息。其中，若通信设备为终端，则信号强度可以根据接收对应多个第二空间信息的信号测量得到。例如，通过测量使用某个空间信息传输的PDCCH的DMRS信号质量或使用某个空间信息传输的RS质量，得到该空间信息的信号强度。采用该可能的实现方式，若目标对象为上行信道或上行信号，目标对象的传输采用与信号强度最强的第二空间信息对应的第一空间信息，可以保证上行信道或上行信号传输的可靠性。
或者，在另一个可能的实现方式中，目标空间信息也可以为多个第二空间信息中预先指定的一个或多个第二空间信息。例如，参考资源的第一个空间信息。
在另一个可能的实现方式中，若参考资源包括多个子参考资源，则目标空间信息可以为多个所述子参考资源中一个或多个预设子参考资源对应的第二空间信息。例如，若参考资源包括多个搜索空间用于传输同一PDCCH，所述多个搜索空间关联不同CORESET，且每个CORESET对应多个空间信息中的一个，则目标空间信息可以为多个CORESET中CORESET ID最小的CORESET对应的空间信息；或者目标空间信息可以为多个搜索空间中的某个搜索空间关联的CORESET所对应的空间关系。
在上述可能的实现方式中，可以预先设置或约定所述预设子参考资源对应的第二空间信息的数量为一个或多个。例如，通过协议规定CORESET#0对应的空间信息(例如，TCI状态或QCI)为一个，或者，如果DCI调度指示目标对象(例如，PDSCH或PUSCH)为多TRP传输，则也可以预先设置或约定或激活预设子参考资源对应的第二空间信息的数量为多个。即在该可能的实现方式中，可以预先设置或约定或激活预设子参考资源对应的第二空间信息的数量与目标空间信息中包括的第二空间信息的数量相同。
或者，在另一个可能的实现方式中，若参考资源包括多个子参考资源，所述目标空间信息为所述多个子参考资源对应的多个第二空间信息中信号强 度最强的一个或多个第二空间信息。其中，若通信设备为终端，则信号强度可以根据来自多个TRP发送的信号测量得到，例如，通过测量使用某个空间信息传输的PDCCH的DMRS信号质量或使用某个空间信息传输的RS质量，得到该空间信息的信号强度。
在一个可能的传输方式中，目标对象可以具有多个传输资源，则目标对象在不同传输资源上传输采用的第一空间信息可以按照映射规则与目标空间信息包括的多个第二空间信息对应，其中，所述多个传输资源包括以下至少一项：时分复用的多个传输资源、频分复用的多个传输资源、空分复用的多个传输资源和码分复用的多个传输资源。
例如，目标对象在不同频率上传输，则目标对象在不同频率上传输采用的第一空间信息可以按照预先设置的映射规则与目标空间信息包括的多个第二空间信息对应。例如，目标空间信息包括的多个第二空间信息：空间信息1和空间信息2，目标对象在频域正交的子载波组1和子载波组2上传输，则可以按照映射规则确定目标对象在子载波组1上采用的第一空间信息与空间信息1对应，在子载波组2上采用的第一空间信息与空间信息2对应。
或者，目标对象也可以在正交的时间资源上多次传输，每次传输采用的第一空间信息按照映射规则与目标空间信息包括的多个第二空间信息中的一个第二空间信息对应。例如，按照交替的映射规则，如目标空间信息包括两个第二空间信息：空间信息1和空间信息2，则目标对象的第一次传输的第一空间信息与空间信息1对应，第二次传输的第一空间信息与空间信息2对应，第三次传输的第一空间信息与空间信息1对应，第四次传输的第一空间信息与空间信息2对应，如此交替映射。或者，也可以采用连续n次重复对应同一个第二空间信息的映射规则，例如，n＝2，目标空间信息包括两个第二空间信息：空间信息1和空间信息2，则目标对象的第一次传输的第一空间信息与空间信息1对应，第二次传输的第一空间信息与空间信息1对应，第三次传输的第一空间信息与空间信息2对应，第四次传输的第一空间信息与 空间信息2对应，如此循环映射。
或者，目标对象在不同空域资源(例如，MIMO的不同层)上传输，则目标对象在不同空间上传输采用的第一空间信息可以按照预先设置的映射规则与目标空间信息包括的多个第二空间信息对应。例如，目标空间信息包括的多个第二空间信息：空间信息1和空间信息2，目标对象在层1和层2上传输，则可以按照映射规则确定目标对象在层1上采用的第一空间信息与空间信息1对应，在层2上采用的第一空间信息与空间信息2对应。
或者，在另一个可能实现的传输方式中，目标对象具有一个传输资源或多个传输资源，目标空间信息为多个所述第二空间信息中的一个，即在该可能的实现方式中，即使目标对象具有多个传输资源，在每个传输资源上传输采用的第一空间信息对应相同的第二空间信息，即在各个传输资源上传输采用的第一空间信息相同。
在上述各个可能的实现方式中，若传输目标对象的终端配置有多个第一标识，则所述参考资源对应的第一标识与目标对象对应的第一标识相同。例如，第一标识可以为无线资源控制(Radio Resource Control，RRC)参数：CORESETPoolIndex(CORESET池索引)，通常用于标识TRP。网络可以为终端配置多个CORESET关联到不同的CORESETPoolIndex值以区分各个CORESET所属的TRP。
在一个可能的实现方式中，所述参考资源可以与所述目标对象位于同一时间单元。即在该可能的实现方式中，目标对象的第一空间信息与同一时间单元内的参考资源的第二空间信息对应。
在上述可能的实现方式中，一个时间单元可以为一个时隙，或者，也可以为一个时隙中的部分正交频分复用(Orthogonal frequency division multiplex，OFDM)符号，或者，也可以为多个时隙，或者，也可以为多个时隙中的部分OFDM符号，具体本实施例中不作限定。

下面以终端为例，通过不同的目标对象，对本申请实施例提供的技术方案进行说明。
实施例一
在本实施例中，以目标对象为PDSCH为例，对本申请实施例提供的技术方案进行说明。
在该实施例中，UE检测到的DCI所在PDCCH对应多个TCI状态时，若DCI中没有指示PDSCH的TCI状态，例如，检测到的DCI为DCI format 1_0或检测到的DCI为未配置tci-PresentInDCI的DCI format 1_1或DCI format  1_2；或者，检测到的DCI中指示了一个TCI状态，但该DCI所在PDCCH的最后一个OFDM符号与该PDCCH调度的单时隙或多时隙PDSCH的第一个OFDM符号之间的符号间隔小于第一门限值(例如，timeDurationForQCL)，则该PDCCH调度的PDSCH的TCI状态或QCL根据参考资源(预定的CORESET，即最近的时间单元的检测搜索空间所关联的CORESET)对应的TCI状态或QCL确定。
在多TRP场景下的PDCCH可以采用以下方式进行增强：(1)一个PDCCH的时频资源基于某种资源粒度按照一定的规则分别对应不同TCI状态以FDM或者TDM方式发送；(2)一个PDCCH的多次传输对应不同的TCI状态，以SDM、FDM、TDM或者它们之间的组合方式发送。
因此，UE检测到的DCI所在PDCCH对应多个TCI状态包括但不限于以下1)至4)项。
1)UE检测到的一个PDCCH属于一个第一搜索空间或PDCCH的多次传输属于一个第一搜索空间，并且该第一搜索空间关联一个CORESET，其中该CORESET对应至少两个TCI状态。
2)UE检测到的一个PDCCH属于一个第二搜索空间或PDCCH的多次传输属于一个第二搜索空间，并且该第二搜索空间关联至少两个CORESET，其中每个CORESET对应一个TCI状态。
3)UE检测到的PDCCH的多次传输属于不同的第三搜索空间(即一个搜索空间组)，并且每个第三搜索空间都关联同一个CORESET，其中该CORESET对应至少两个TCI状态。
4)UE检测到的PDCCH的多次传输属于不同的第四搜索空间，并且每个第四搜索空间分别关联一个CORESET，其中每个CORESET对应一个TCI状态。
在该实施例中，在检测到的DCI未指示TCI状态或者检测到的DCI中指示了一个TCI状态的情况下，如果该DCI所在PDCCH的最后一个OFDM符 号与该PDCCH调度的单时隙或多时隙PDSCH的第一个OFDM符号之间的符号间隔offset1小于第一门限值timeDurationForQCL，则在未配置多个第一标识(CORESETPoolIndex)且激活的TCI码点均只对应一个TCI状态或QCL，则可以按照以下方式(1)和(2)确定PDSCH的空间信息(例如，TCI状态)。
(1)如果最近的时间单元(例如，时隙、子时隙、或一个时隙或多个时隙中多个OFDM符号(例如SPAN))的检测搜索空间(monitored search space)所关联的CORESET对应K个不同TCI状态，则该PDSCH的TCI状态与该K个不同TCI状态中的M个相同，其中，K为大于1的整数，M为大于等于1的整数。例如，与最近的时间单元的检测搜索空间所关联的CORESET对应的多个不同TCI状态中的第n个或第n个至第(n+M-1)个TCI状态相同，其中，n的取值可以预先设置或约定。或者，该PDSCH的TCI状态为该K个不同TCI状态中信号强度最强的M个TCI状态。
(2)如果最近时间单元的检测搜索空间关联多个CORESET，则该PDSCH的TCI状态或QCL对应于该多个CORESET中标识(ID)最小的CORESET所对应的TCI状态。或者，该PDSCH的TCI状态为该多个CORESET对应的多个TCI状态中信号强度最强的M个TCI状态，其中，M为大于等于1的整数。在该可能实现方式中，可以预先设置或约定具有最小标识的CORESET配置有M个TCI状态。具体可以参见表1。其中，在该实施例中，表1中的目标对象为PDSCH。
在该实施例中，在检测到的DCI未指示TCI状态，如果该DCI所在PDCCH的最后一个OFDM符号与该PDCCH调度的单时隙或多时隙PDSCH的第一个OFDM符号之间的符号间隔offset1大于等于第一门限值timeDurationForQCL，则在未配置多个第一标识(CORESETPoolIndex)且激活的TCI码点均只对应一个TCI状态或QCL，则可以按照以下方式(1)和(2)之一确定PDSCH的TCI状态。
(1)若检测到DCI所在PDCCH的时频资源基于某种资源粒度按照一定 的规则分别对应不同空间信息以FDM或者TDM方式发送，确定单次传输的所述PDSCH或多次传输的所述PDSCH的空间信息为所述PDCCH(即PDCCH为PDSCH的参考资源)对应的多个空间信息中的一个。即每次传输PDSCH的TCI状态对应于PDCCH的其中一个TCI状态或QCL。或者，对于多次传输的所述PDSCH，确定各次传输的所述PDSCH的空间信息按照预定规则分别与所述PDCCH对应的多个空间信息中的一个对应。例如，交替对应，或者连接n次传输对应相同的空间信息。例如，PDCCH基于某种资源粒度按照一定的规则分别对应TCI状态1和TCI状态2，则多次传输的PDSCH的第一次传输的空间信息与TCI状态1对应，第二次传输的空间信息与TCI状态2对应，第三次传输的空间信息与TCI状态1对应，如此交替对应。
(2)若检测到的DCI所在PDCCH的多次传输对应不同的空间信息，以SDM、FDM、TDM或者它们之间的组合方式发送，确定单次传输的所述PDSCH或多次传输的所述PDSCH的空间信息与所述PDCCH的多次传输中的一次传输的空间信息对应，例如，与PDCCH的第一次或第n次或最后一次传输的空间信息对应；或者，对于多次传输的所述PDSCH，确定各次传输的所述PDSCH的空间信息按照预定规则分别与所述PDCCH的多次传输的多个空间信息中的一个对应。例如，交替对应。例如，PDCCH第一次传输的TCI状态为TCI状态1，第二次传输的TCI状态为TCI状态2，则多次传输的PDSCH的第一次传输的空间信息与TCI状态1对应，第二次传输的空间信息与TCI状态2对应，第三次传输的空间信息与TCI状态1对应，如此交替对应。具体可以参见表1。

在多TRP场景下，控制信令可以来自多个TRP，称为多DCI调度的多TRP，即每个TRP发送各自的PDCCH，每个PDCCH调度各自的PDSCH、APCSI-RS、PUSCH或SRS，为UE配置的多个CORESET关联到不同的RRC参数CORESETPoolIndex，对应不同的TRP。
在该实施例中，在检测到的DCI未指示TCI状态或者检测到的DCI中指 示了一个TCI状态的情况下，如果该DCI所在PDCCH的最后一个OFDM符号与该PDCCH调度的单时隙或多时隙PDSCH的第一个OFDM符号之间的符号间隔offset1小于第一门限值timeDurationForQCL，UE配置多个第一标识(CORESETPoolIndex)且激活的TCI码点均只对应一个TCI状态或QCL的情况下，PDSCH的空间信息与未配置多个第一标识相似，不同之处在于，在这种情况下，PDSCH的TCI状态或QCL对应最近时间单元的检测搜索空间(monitored search space)所关联的、与该PDSCH同属一个CORESETPoolIndex的CORESET对应的一个或多个TCI状态。如表2所示。在本实施例中，表2中的目标对象为PDSCH。
表2.
Figure PCTCN2021115055-appb-000003
在多TRP场景下，控制信令也可以来自一个TRP，称为单DCI调度的多TRP，即由一个TRP发送PDCCH调度一个PDSCH，该PDSCH包括多种多TRP的传输方案：PDSCH的不同层的数据来自不同TRP；或者不同频域子载波上的数据来自不同的TRP；或者各次时域重复来自不同TRP。在这种情况下，MAC CE激活最多8个TCI码点(codepoint)，其中至少一个TCI码点对应两个TCI状态。当检测到的DCI中TCI域指示的TCI码点对应两 个TCI状态且指示有一个TCI状态包含“QCL-TypeD”(即空间波束类型的QCL)时，则指示调度上述多TRP传输的PDSCH。具体传输方案由其他方式确定，例如高层参数配置。如果上述时间偏移offset1小于timeDurationForQCL，则UE可以使用多个默认接收波束接收PDSCH，即UE可以认为服务小区的PDSCH的DMRS端口与包含两个不同TCI状态的码点中最小索引的码点所指示的两个TCI状态RS是QCL的。如表3所示。
表3.至少一个激活的TCI码点对应2个TCI状态(单DCI的MTRP)
Figure PCTCN2021115055-appb-000004
另外，目标对象还可以为跨载波调度PDSCH，如果传输调度DCI的PDCCH在第一CC上，而该DCI调度的PDSCH在第二CC(其中，第一CC和第二CC不同)上，且UE被配置为允许使用跨载波调度的默认波束，则当前上述Offset1小于timeDurationForQCL+Δ1，其中，Δ1为由于两个CC的子载波间隔不相同的时间调整值，以及DCI中不包含TCI域时，如果第二CC上激活BWP上激活的用于PDSCH的TCI状态有多个TCI状态。则UE接收PDSCH的QCL可以对应于该多个TCI状态中的一个，例如，第一个，或者，UE接收PDSCH的QCL对应于多个TCI状态中信号最强的一个。在该实施例中，参考资源为激活的多个空间信息，具体为用于PDSCH的多个TCI状态。
实施例二
本实施例中，以目标对象为信道状态信息(Channel State Information，CSI)参考信号(Reference Signal，RS)为例，对本申请实施例提供的技术方案进行说明。
对于CSI-RS未配置参数重复(repetition)为“on”的情况，如果UE被配置了一个CSI-RS资源，该CSI-RS资源与关联到一个CORESET的一个搜索空间处于相同的一个或多个OFDM符号，则该CSI-RS的空间信息可以根据该CORESET(即参考资源)确定，如果该CORESET对应多个TCI状态或QCL，则UE可以假设该CSI-RS与关联到该CORESET的所有搜索空间集的PDCCH的DMRS对应的多个TCI状态或QCL之一是QCL-TypeD的，如果QCL-TypeD可用，例如，第一个TCI状态或QCL，或者该CORESET对应多个TCI状态或QCL中信号强度最强的一个或多个TCI状态或QCL。即UE可以确定该CSI-RS的空间信息与该CORESET其中一个或多个TCI状态或QCL对应，该一个或多个TCI状态或QCL可以是预先指定的，例如，第一个，也可以为该CORESET对应的多个TCI状态或QCL中信号强度最强的一个或多个TCI状态或QCL。
本实施例提供的技术方案，对于CSI-RS与CORESET处于不同intra-band载波上也适用。
实施例三
本实施例中，以目标对象为DCI指示的CSI触发状态关联的非周期性CSI-RS(Aperiodic CSI-RS，A-CSI-RS)为例，对本申请实施例提供的技术方案进行说明。
在本实施例中，UE检测到的DCI中指示的CSI触发状态关联A-CSI-RS，其中，所述A-CSI-RS所在的BWP至少配置了一个CORESET。
在本实施例中，在所述A-CSI-RS的调度偏移小于第二预设值，则所述A-CSI-RS的空间信息由该A-CSI-RS所在的BWP配置的CORESET确定，其中，所述调度偏移为传输所述DCI的PDCCH的最后一个符号与CSI-RS资源集配置参数中未配置传输信息(trs-Info)的A-CSI-RS资源的第一个符号之间的符号数。
在本实施例中，如果UE未配置多个CORESETPoolIndex(即所述第一标识)且激活的TCI码点均只对应一个TCI状态，如果所述A-CSI-RS与其他下行信号不具有相同的OFDM符号，且所述A-CSI-RS所在的BWP至少配置了一个CORESET，若调度偏移offset2小于第二预设值(即门限2)则可以按照上述表1中的方式1-1-1、2-1-1或2-1-2确定所述A-CSI-RS的空间信息。具体如表4所示。
表4.
Figure PCTCN2021115055-appb-000005
Figure PCTCN2021115055-appb-000006
其中，其他下行信号包括：调度偏移大于或等于timeDurationForQCL的PDSCH、周期CSI-RS(P-CSI-RS)、半持续CSI-RS(SP-CSI-RS)和调度偏移大于或等于门限2的AP-CSI-RS。
其中，当UE报告门限值beamSwitchTiming是{14,28,48}之一且网络未配置enableBeamSwitchTiming-r16时，门限2为UE报告的门限值beamSwitchTiming；当UE报告门限值beamSwitchTiming是{224,336}之一且网络未配置enableBeamSwitchTiming-r16时，门限2为48。如果触发A-CSI-RS的PDCCH与A-CSI-RS具有不同的子载波间隔(例如跨载波调度可能出现的情况)门限2为beamSwitchTiming+Δ2(Δ2为子载波间隔不相同的时间调整值)。
而在UE配置多个CORESETPoolIndex(即所述第一标识)，且采用多DCI调度的MTRP的情况下，
在该实施例中，如果所述A-CSI-RS与其他下行信号不具有相同的OFDM符号，且所述A-CSI-RS所在的BWP至少配置了一个CORESET，若调度偏移offset2小于第二预设值(即门限2)则可以按照上述表1中的方式1-1-1、2-1-1或2-1-2确定所述A-CSI-RS的空间信息，其中，表1中的CORESET为与目标对象(在本实施例为所述A-CSI-RS)对应相同的第一标识的CORESET。
实施例四
本实施例中，以目标对象为PUCCH为例，对本申请实施例提供的技术方案进行说明。
如果一个UE：
(1)报告了beamCorrespondenceWithoutUL-BeamSweeping，且
(2)在PUCCH-PowerControl中未被配置pathlossReferenceRSs，且
(3)被配置了enableDefaultBeamPlForPUCCH，且
(4)未被配置PUCCH-SpatialRelationInfo
则该UE发送PUCCH的空间信息(空间关系)根据参考资源对应的空间信息确定，其中，参考资源包括：第一目标CORESET，所述第一目标CORESET为发送所述PUCCH的小区的激活下行BWP上标识最小的CORESET。
在本实施例中，确定所述目标对象的第一空间信息与目标空间信息对应可以包括以下之一：
(1)确定单次传输的PUCCH或者多次传输的PUCCH的第一空间信息与所述目标空间信息对应；例如，对于单次PUCCH发送或多次PUCCH发送，则发送PUCCH的空间关系对应于上述CORESET对应的多个TCI状态或QCL之一的TCI状态或QCL，例如第一个TCI状态或多个TCI状态对应信号较强的TCI状态。
(2)对于多次传输的PUCCH，确定各次传输的PUCCH的第一空间信息按照预定规则分别与所述第一目标CORESET的多个空间信息中的一个对应。例如，对于多次PUCCH重复发送，则发送每次PUCCH发送的空间关系按规则分别对应于上述CORESET对应的多个TCI状态或QCL之一的TCI状态或QCL，例如交替对应。
实施例五
本实施例中，以目标对象为PUSCH为例，对本申请实施例提供的技术方案进行说明。
在本实施例的一个可能的实现方式中，若检测到的DCI为DCI format 0_0，由于上行调度DCI format 0_0中无PUSCH发送空间关系指示(SRI)，因此，DCI format 0_0调度的PUSCH的空间关系根据传输PUSCH的小区的激活上行BWP上的目标PUCCH资源(即所述PUSCH的参考资源)对应的空间信息确定，其中，所述目标PUCCH资源为该小区的激活上行BWP上的具有最 小标识的PUCCH资源。在这种情况下，确定所述目标对象的第一空间信息与目标空间信息对应可以包括以下任一项：
(1)确定单次传输的PUSCH或者多次传输的PUSCH的第一空间信息与所述目标PUCCH资源对应的多个第二空间信息中的一个；发送单个PUSCH或发送多次PUSCH的空间关系对应于该目标PUCCH资源的多个空间关系之一，例如第一个或预先配置的；
(2)对于多次传输PUSCH，确定各次传输的PUSCH的第一空间信息按照预定规则分别与所述目标PUCCH资源对应的多个第二空间信息中的一个对应。例如，发送多次PUSCH时，每次PUSCH的传输机会的空间关系按规则分别对应于该PUCCH资源的多个空间关系之一，例如交替对应。
在本实施例的另一个可能实施方式中，若处于RRC连接态的UE高层参数enableDefaultBeamPlForPUSCH0_0被配置为“enabled”，且在激活的上行BWP上未被配置PUCCH资源或者在激活的上行BWP上配置的所有PUCCH资源均未配置空间关系，则所述PUSCH的参考资源包括：第二目标CORESET，所述第二目标CORESET为发送所述PUSCH的CC或小区的激活下行BWP上标识最小的CORESET，如果该标识最小的CORESET对应多个TCI状态，则确定所述目标对象的第一空间信息与目标空间信息对应，包括以下任一项：
(1)确定单次传输的PUSCH或者多次传输的PUSCH的第一空间信息与所述目标空间信息对应；例如，对于单次PUSCH发送或多次PUSCH发送，发送PUSCH的空间关系对应于上述第二CORESET对应的多个TCI状态或QCL之一的TCI状态或QCL，例如第一个TCI状态或多个TCI状态对应信号较强的TCI状态。
(2)对于多次传输的PUSCH，确定各次传输的PUSCH的第一空间信息按照预定规则分别与所述第二目标CORESET的多个空间信息中的一个对应。例如，对于多次PUSCH重复发送，则发送每次PUSCH发送的空间关系按规则分别对应于上述第二CORESET对应的多个TCI状态或QCL之一的 TCI状态或QCL，例如交替对应。
实施例六
本实施例中，以目标对象为探测参考信号(Sounding Reference Signal，SRS)为例，对本申请实施例提供的技术方案进行说明。
当UE满足：
(1)高层参数enableDefaultBeamPlForSRS被配置为“enabled”，且
(2)FR2未被配置高层参数spatialRelationInfo，除SRS-ResourceSet中的参数usage设为“beamManagement”或{设为“nonCodebook”并被配置了associatedCSI-RS}或SRS资源被配置了SRS-PosResourceSet-r16之外，且(3)未被配置多个不同值的CORESETPoolIndex(非多DCI调度的MTRP)，且
(4)未被配置包含对应两个TCI状态的TCI码本(非单DCI调度的MTRP)，
则所述SRS的空间关系根据传输该SRS的载波或小区上激活的上行BWP上标识最小的CORESET(即第三目标CORESET)确定，如果第三目标CORESET对应多个TCI状态或QCL，确定所述目标对象的第一空间信息与目标空间信息对应可以包括以下任一项：
(1)发送一个SRS资源的空间关系或一个SRS资源的多次重复发送的空间关系或发送多个SRS资源的空间关系对应具有“QCL-TypeD”的参考信号(RS)，如果QCL-TypeD可用，该RS对应于所述第三目标CORESET对应多个TCI状态或QCL之一，例如第一个TCI状态，或多个TCI状态对应信号最强的TCI状态。
(2)发送一个SRS资源的多次重复中的每次SRS重复发送的空间关系或发送多个SRS资源中的每个SRS资源的空间关系按规则分别对应具有“QCL-TypeD”的RS，如果QCL-TypeD可用，各个RS按规则分别对应于所述第三目标CORESET对应多个TCI状态或QCL之一，例如交替对应。
实施例七
本实施例中，以目标对象为CORESET#0为例，对本申请实施例提供的技术方案进行说明。
在CORESET当中，CORESET#0可以具有与其它CORESET不同的特性。例如，CORESET#0可以由在物理广播信道(PBCH)上发送的主信息块(MIB)作为初始带宽部分(BWP)设置的部分来提供。CORESET#0可以是用于监视用于调度携载***信息块(SIB1)的物理下行链路共享信道(PDSCH)的物理下行链路控制信道(PDCCH)的CORESET，并且可以被用于接收其它***信息和附加设置信息。另一方面，可以通过专用RRC信令提供另一CORESET，并且可以使用该CORESET接收UE特定的控制信息。另外，CORESET#0可能没有针对TCI状态的显式设置。因此，需要确定CORESET#0的空间信息。而CORESET#0的TCI状态与同步信号/物理广播信道块(SSB，也可以称为同步信号块)关联的参考信号相关，因此，CORESET#0的TCI状态根据SSB(即参考资源)对应的空间信息确定。
当CORESET#0的搜索空间(即SS#0)配置了多个空间信息，例如，SS0配置了多个跟踪参考信号(Tracking Reference Signal，TRS)，每个TRS关联一个SSB，不同的关联的SSB不同，而不同的SSB配置不同的空间信息，在这种情况下，CORESET#0的参考资源(即SSB)对应多个空间信息。在本实施例中，确定CORESET#0的空间信息(例如，TCI状态或QCL)与其中一个SSB的空间信息对应，例如，预先指定的一个SSB，UE可以在检测到该SSB时，根据该SSB的空间信息(例如，接收波束)，确定CORESET#0的空间信息与该SSB的空间信息对应。
需要说明的是，虽然上述各个实施例以终端为例进行说明，但并不限于此，网络侧设备可以采用与终端相应的方式，确定目标对象的第一空间信息，并根据第一空间信息进行目标对象的传输，具体本申请实施例中不再赘述。
图3示出本申请实施例中的检测机会的确定方法的一种流程示意图，该 方法300可以由终端执行。换言之，所述方法可以由安装在终端上的软件或硬件来执行。如图3所示，该方法可以包括以下步骤。
S310，在CORESET#0关联的搜索空间配置多个空间关系，多个所述空间关系对应多个同步信号块，且不同所述同步信号块对应不同的空间关系的情况下，终端根据一个所述同步信号块确定与所述搜索空间的检测机会，或根据所述多个同步信号块确定所述搜索空间的多个检测机会。
例如，终端在检测到一个同步信号块时，可以根据检测到的该同步信号块，确定CORESET#0的搜索空间的检测机会，并在相应的检测机会上检测CORESET#0。或者，终端也可以根据检测到的多个SSB，确定CORESET#0的搜索空间的多个检测机会。
在一个可能的实现方式中，终端根据一个所述同步信号块确定与所述搜索空间的检测机会，包括：根据所述一个所述同步信号块确定所述搜索空间的检测机会的时频资源及空间关系；根据所述多个同步信号块确定所述搜索空间的多个检测机会，包括：根据所述多个同步信号块确定所述搜索空间的多个检测机会的时频资源及空间关系。即在该可能的实现方式中，确定所述搜索空间的检测机会包括：确定检测机会的时频资源及空间关系。
对于非广播PDCCH，网络侧设备和UE在连接模式下，对SSB/CORESET#0/SS#0保持相同的理解，因此，在本实施例中，可以根据检测到SSB确定CORESET#0的SS#0的检测机会，配置多个SSB的情况下，可以根据其中一个SSB确定一个检测机会，也可以根据多个SSB确定多个检测机会。
通过本申请实施例提供的检测机会的确定方法，可以在CORESET#0关联的搜索空间配置多个空间关系，多个所述空间关系对应多个同步信号块，且不同所述同步信号块对应不同的空间关系的情况下，根据一个所述同步信号块确定与所述搜索空间的检测机会，或根据所述多个同步信号块确定所述搜索空间的多个检测机会。
