另外，本发明实施例中所述的索引(index)和指示(indicator)是可以相互替换的概念。

在本发明实施例中，在多传输接收节点或多面板(Multi-Panel)传输的场景下，一个面板可以对应一个端口组(如天线端口组，天线组)，两者是一一对应的，也可以相互替换。面板是指天线面板，一个传输接收点(Transmission Reception Point，TRP)或者通信节点(包括但不限于终端，基站等)都可以包括至少一个天线面板。每个面板上有一个或者多个天线阵子，多个阵子可以虚拟成一个天线端口。一个面板上的天线端口可以分成一个端口组。一个面板又可以分成多个子面板，每个子面板包括的多个天线端口可以分成一个端口组。比如双极化的天线，正45°极化的天线为一个子面板，而负45°极化的天线为一个子面板。本申请实施例中把面板和子面板都统称为面板，用panel表示，这里的面板可以用端口组代替。
在NR等标准中，PDCCH是需要映射到一组资源单元(resource element，RE)上的，比如包括一个或者多个控制信道单元(Control Channel Element，CCE)，其中，一个RE在频域上包括一个子载波，而在时域上包括一个符号，一个CCE包括多个RE。而用于传输PDCCH的一个或者多个CCE的集合，有时也叫控制资源集合(Control resource set，CORESET)，其在频域上包括多个物理资源块，而在时域上包括K个符号，K为自然数，比如K可以取1、2、3的整数。而为了检测PDCCH，将某个聚合等级的候选PDCCH配置成一个集合，这个等级的下的候选PDCCH集合就是搜索空间(Search Space，SS)，而多个搜索空间的集合形成一个搜索空间集合(SS set，SSSET，或SSS)，每个终端可以配置至少一个搜索空间集合。而为了检测PDCCH。会在搜索空间里配置当前终端的PDCCH检测的时机(即occasion)，以及检测的PDCCH候选(即candidate)，或PDCCH候选。另外，PDCCH包括多种格式format，每种格式都对应一个相对应格式下的下行控制信息DCI，每个DCI中又包括多个具体的信令指示域。其中，检测也可以称为监测，盲检，主要是用来确 定候选的多个PDCCH哪个是用于给终端传输下行控制信息的PDCCH。
本发明实施例中所述的传输可以指发送或接收，比如数据或信号的传输可以是指数据或信号的发送，也可以是数据或信号的接收，这里的信号包括各种参考信号，数据包括物理上行共享信道或物理下行共享信道传输的数据。
本发明实施例中，为了更好地传输PUSCH或者PDSCH，将连续K1个符号和L1个频域子载波的一组资源单元(Resource Element，RE)形成一个资源块(Resource block，RB，有时也叫物理资源块，Physical Resource block，PRB，或RB)，K1和L1为正整数，比如K1＝12或者14，L1＝12。这里，一个RE包括一个符号和一个子载波对应的用于承载一个调制信号的最小资源单位。
为了解调或者获取RE上调制的物理信道上的携带的信息(包括数据或者信号)，需要估计所述RE上的无线信道的值，而这个值一般是由解调参考信号(Demodulation Reference Signal，DMRS)估计的，并用DMRS对应的RE上的信道插值获得物理信道上的信道。
在本发明实施例中，无线网络临时标识(Radio Network Temporary Identifier，RNTI)用于第一通信节点和第二通信节点之间的信号信息内部作为第二通信节点的标识。主要包括以下至少之一：用于标识系统消息的SI-RNTI、用于标识寻呼信息的P-RNTI、标示用户发随机接入前导所使用的资源块的RA-RNTI、用于标识用户业务的C-RNTI、用于标识PUCCH上行功控信息的TPC-PUCCH-RNTI、用于标识PUSCH上行功控信息的TPC-PUSCH-RNTI。
相关技术中，多个传输信号可能来自多个通信节点(比如传输节点，基站等)，M个传输信号可以来自M个不同的TRP，或者来自M个不同的天线面板，或者M个不同的带宽部分(Bandwidth Part，BWP)，或者M个不同的载波组件(Carrier Component，CC)，其中所述的M个面板 或者M个BWP或者M个CC可以属于同一个TRP，也可以属于多个TRP。而为了区别来自不同TRP的控制信道，会对候选的CORESET进行分组，每个组包括至少一个CORESET，每个CORESET有一个高层参数索引，比如CORESET组索引coresetPoolIndex-r16。当多个传输信号来自不同的传输节点时，可以通过一个DCI通知物理下行控制信息，这种方式叫基于单物理下行控制信息(Single DCI)的联合传输，而如果通过2个或者两个以上的DCI通知物理下行控制信道，这种方式叫基于多个物理下行控制信息(Multi DCI)的联合传输。
为了提高可靠性，一种技术是用混合自动重复传输(Hybrid automatic repeat request，HARQ)，即终端或者基站在接收到传输块后，如果检测发现接收是正确的，反馈一个确定信息(Acknowledgement，ACK)，否则反馈一个否定信息(Negative Acknowledgement，NACK)，而ACK和NACK信息可以统称为HARQ应答，当然也可以称为如下之一：HARQ应答信息，HARQ-ACK信息，HARQ-ACK，HARQ-ACK应答，ACK/NACK信息，ACK/NACK码本，如果没有特别说明，本发明实施例中的ACK/NACK也可以称为HARQ-ACK。
相关技术中，会对至少一个TRP所对应的所有服务小区(或者载波组件Carrier Component，CC)和高层配置的符合要求的PUCCH检测时机Occasion生成一个HARQ的HARQ-ACK比特集合，比如HARQ-ACK码本，HARQ-ACK子码本，并在PUCCH资源或者PUSCH资源中反馈所述的HARQ-ACK码本。
可以通过高层信令、物理层信令或者约定的方式至少之一确定不同ACK信息的优先级，并且，传输信号对应的ACK信息的优先级满足如下特征至少之一：相同优先级的ACK可以合并到同一HARQ-ACK码本中；不同优先级的ACK不能合并到同一HARQ-ACK码本中；相同优先级的ACK可以合并到物理上行信道中传输中；不同优先级的ACK不能合并到物理上行信道中传输中。
当RRC配置的TCI state数目N0大于一个配置的门限个数N1时，需要根据MAC CE从N0个TCI state中选择N1个TCI state或者TCI state组形成一个集合，然后用DCI的TCI域从这个TCI state集合里选择其中一个TCI state或者TCI state组以指示终端需要使用的QCL取值。其中，DCI里的TCI域用于指示的所述一个TCI state或者TCI state组的值就是一个码点(code point)或者称为TCI codepoint，每个码点和一个TCI state或者TCI state组关联，这里TCI state组包括至少2个TCI state。表1是相关技术中的TCI state映射表格，一种关联方式如表1所示。

传输信号关联的空间参数是指以下之一：传输信号对应的空间参数，所述用于发送所述传输信号的空间参数，用于接收所述传输信号的空间参数，与所述传输信号准共址的参考信号。
以下对于本发明实施例中的空间参数确定方法及装置的工作方式进行阐述。
实施例1
本实施例提供了一种空间参数确定方法，图2是根据本发明实施例提供的空间参数确定方法的流程图(一)，如图2所示，本实施例中的空间参数确定方法包括：
S102，根据第一配置信息确定N类传输信号的优先级信息；其中，N为大于1的整数；
S104，根据优先级信息确定同一符号对应的空间参数信息；其中，空间参数信息用于传输N类传输信号中至少一类传输信号。
需要进一步说明的是，上述实施例中，传输信号可以为参考信号，物理控制信道，物理共享信道等等，本发明实施例对此不作限定；上述符号通常可为时域符号；上述优先级信息即用于指示传输信号的优先级。
需要进一步说明的是，上述实施例可以根据传输信号的优先级信息确定同一符号对应的空间参数信息，并根据所述确定的传输信号的空间参数对应的波束传输所述的至少一个传输信号，比如用于接收所述至少一个传输信号的接收波束。这里只是至少一个传输信号，可以是所述N类传输信号的所有传输信号，也可以是所述传输信号中优先级为高的K个传输信号。
通过本实施例中的空间参数确定方法，由于可以根据第一配置信息确定N类传输信号的优先级信息；其中，N为大于1的整数；根据优先级信息确定同一符号对应的空间参数信息；其中，空间参数信息用于传输N类传输信号中至少一类传输信号。因此，通过本发明实施例可以解决相关技术中如何有效确定同一个符号对应的空间参数的问题，以达到用所述空间参数在所述同一个符号上有效传输所述至少一类传输信号的效果。
可选地，本实施例中的空间参数确定方法，可在Multi-TRP传输或Multi-Panel或高频传输的场景下，在同一符号内涉及N个传输信号时，可有效确定对应的空间参数；例如，在UE接收到多个PDSCH，如PDSCH1 和PDSCH2的过程中，通过本实施例中的空间参数确定方法以令UE确定优先级较高的传输信号对应的接收波束为PDSCH1和PDSCH2的接收波束。
在一实施例中，上述N类传输信号中，同一类传输信号关联相同的空间参数信息，不同类传输信号关联不同的空间参数信息。
在一实施例中，上述步骤S104中，根据优先级信息确定同一符号对应的空间参数信息，包括：
确定N类传输信号中优先级为高的K类传输信号关联的空间参数为同一符号对应的空间参数信息；其中，K为正整数且小于等于T；T为同一个符号对应的空间参数个数的极大值，T由高层配置或根据用户终端UE能力确定。
需要进一步说明的是，上述实施例中，K类传输信号即为N类传输信号中优先级为高的多类传输信号，K类传输信号的确定方式可以有多种，如在N类传输信号选取优先级较高的多类传输信号作为K类传输信号，例如，在本实施例中存在N类传输信号(比如N为5)时，可将N类传输信号按照优先级从高到底进行排序，选取其中优先级较高的前K类传输信号作为上述实施例中的K类传输信号(比如K为3)；或者，可直接在N类传输信号选取优先级最高的多类传输信号作为K类传输信号，例如，在本实施例中存在N类传输信号(比如N为5)时，上述N类传输信号存在两个不同的优先级级别(高优先级与低优先级)，即可选取优先级最高的多类传输信号作为K类传输信号。
另一方面，对于同一符号而言，可由高层配置或根据UE能力确定该同一符号对应的的空间参数个数的极大值T，即最大空间参数个数，K的个数需满足T的限制。
需要进一步说明的是，上述实施例中，同一个符号的空间参数个数即为通信节点同一个时域符号所能传输的最大空间参数个数；以此，根据上述实施例中的技术方案，可令确定的空间参数与通信节点在同一个时域符 号所能使用的空间参数的个数相对应。通过上述实施例中记载的技术方案，可实现UE对应一个TRP发送的多个传输信号(比如不同CC或者BWP发送的传输信号)进行空间参数的确定，或对不同的TRP发送的传输信号进行空间参数的确定。
在一实施例中，上述步骤S104中，根据优先级信息确定同一符号对应的空间参数信息，包括：
根据第二配置信息将N类传输信号区分为C个传输信号组，其中，每个传输信号组中的一类或多类传输信号关联相同的第二配置信息；C为正整数，且C小于或等于N。在另一个实施例中，可根据高层信令或者根据预定方式将第二配置信息分成C个组，每个组第二配置信息组包括至少一个第二配置信息，将一个或者多个传输信号关联相同第二配置信息组的传输信号分成一个传输信号组。比如所述的第二配置信息为CORESET组，那么传输信号对应的COSRESET组索引相同的传输信号为一组。比如将第二配置信息X分成C组，那么传输信号对应的第二配置信息X组索引相同的传输信号为一组，这里，X可以用CORESET索引信息；传输信号对应的确认ACK信息的优先级信息；物理下行控制信息中的优先级指示PI(Priority indicator)信息；虚拟小区号信息；物理小区标识PCI信息；无线网络临时标识RNTI的类型信息；下行控制信息DCI的参数信息；调度时间间隔信息；信道类型信息；载波组件CC索引信息之一替换。
需要进一步说明的是，上述实施例中，根据第二配置信息将N类传输信号区分为C个传输信号组，即根据第二配置信息对N类传输信号进行分组，以得到C个传输信号组。
需要进一步说明的是，对于位于同一组中的多类传输信号也按照本实施例中的传输信号的优先级的确定方法确定传输信号组内的多类传输信号的优先级，以及它们的空间参数。对于位于不同组的传输信号，由于它们可以同时接收，可以不用进一步确定它们之间的优先级，只要分别使用对应传输信号组的空间参数就可以，也可以采用其它预设方式，本发明实 施例对此不作限定。
在一实施例中，上述第二配置信息包括以下至少之一：
控制资源集CORESET组信息；CORESET索引信息；传输信号对应的确认ACK信息的优先级信息；物理下行控制信息中的优先级指示PI(Priority indicator)信息；虚拟小区号信息；物理小区标识PCI信息；无线网络临时标识RNTI的类型信息；下行控制信息DCI的参数信息；调度时间间隔信息；信道类型信息；载波组件CC索引信息。
在一实施例中，上述步骤S104中，根据优先级信息确定同一符号对应的空间参数信息，包括：
对于C个传输信号组中的第i个传输信号组，将第i个传输信号组中优先级为高的K i类传输信号关联的空间参数信息确定为第i个传输信号组中的一类或多类传输信号在同一符号对应的空间参数信息；i为正整数，且i小于等于C；
其中，K i为正整数，且K i小于等于T i；T i为同一符号中第i个传输信号组对应的的空间参数个数的极大值，T i由高层配置或根据UE能力确定。
需要进一步说明的是，上述第i个传输信号组为C个传输信号组中的任意一个传输信号组，即i＝1、2、3……C-1、C。第i个传输信号组中的K i类传输信号，即为该第i个传输信号组中优先级较高的传输信号；对于第i个传输信号组而言，K i类传输信号的确定方式可以有多种，如在第i个传输信号组的多类传输信号中，选取优先级较高的多类传输信号作为K i类传输信号(比如按传输信号优先级从高到底排序，选取优先级较高的前K i类传输信号)，或者，可直接在N类传输信号选取优先级最高的多类传输信号作为K类传输信号；具体方式可参见前述K类传输信号的选取，在此不再赘述。
另一方面，对于每一个第i个传输信号组而言，可由高层配置或根据UE能力确定该同一符号中第i个传输信号组对应的的空间参数个数的极大值，即最大空间参数个数，K i的个数需满足T i的限制。
在一实施例中，C个传输信号组中，每一个传输信号组对应的K i类传输信号所构成的集合为K类传输信号；多个K i的和为K；
其中，K为正整数且小于等于T；K类传输信号为N类传输信号中通过预设方式确定的优先级为高的一类或多类传输信号；T为同一个符号对应的空间参数个数的极大值，T由高层配置或根据用户终端UE能力确定。
需要进一步说明的是，上述C个传输信号组中，每一个传输信号组中K i类传输信号对应的数量K i叠加后即为K类传输信号对应的数量K，即多个Ki之和为K。
在一实施例中，本实施例中的空间参数确定方法还包括：
在C个传输信号组中确定优先级为高的M类传输信号，其中，M为正整数且大于T；
根据传输信号的优先级，确定M类传输信号中优先级为高的T类传输信号关联的空间参数为同一符号对应的空间参数信息。
在一实施例中，上述第一配置信息包括以下至少之一：
CORESET组信息；CORESET索引信息；传输信号对应的ACK信息的优先级信息；物理下行控制信息中的优先级指示PI信息；虚拟小区号信息；PCI信息；RNTI的类型信息；DCI的参数信息；调度时间间隔信息；信道类型信息；CC索引信息。
在一实施例中，上述步骤S102中，根据第一配置信息确定N类传输信号的优先级信息，包括：
在第一配置信息为CORESET组信息的情形下，传输信号对应的CORESET组信息的CORESET组索引越小，确定传输信号的优先级信息所指示的优先级越高；或者，
在第一配置信息为CORESET索引信息的情形下，传输信号对应的CORESET索引越小，确定传输信号的优先级信息所指示的优先级越高；或者，
在第一配置信息为传输信号对应的ACK信息的优先级信息的情形下，传输信号对应的ACK信息的优先级信息越高，确定传输信号的优先级信息所指示的优先级越高，其中，传输信号对应的ACK信息的优先级信息由高层信令确定或由预设方式确定；或者，
在第一配置信息为物理下行控制信息中的优先级指示PI信息的情形下，传输信号对应的物理下行控制信息中的优先级指示PI信息的优先级信息越高，确定传输信号的优先级信息所指示的优先级越高，其中，物理下行控制信息中的优先级指示PI信息由高层信令确定或由预设方式确定；或者，
在第一配置信息为虚拟小区号的情形下，传输信号对应的虚拟小区号越小，确定传输信号的优先级信息所指示的优先级越高；或者，
在第一配置信息为物理小区标识的情形下，传输信号对应的物理小区标识越小，确定传输信号的优先级信息所指示的优先级越高；或者，
在第一配置信息为RNTI的类型信息的情形下，传输信号对应的RNTI的类型的优先级信息越高，确定传输信号的优先级信息所指示的优先级越高，其中，RNTI的类型的优先级信息由高层信令确定或由预设方式确定；或者，
在第一配置信息为DCI的参数信息的情形下，传输信号对应的DCI的参数信息的优先级信息越高，确定传输信号的优先级信息所指示的优先级越高，其中，DCI的参数信息的优先级信息由高层信令确定或由预设方式确定；或者，
在第一配置信息为信道类型信息的情形下，传输信号对应的信道类型信息的优先级信息越高，确定传输信号的优先级信息所指示的优先级越高，其中，信道类型信息的优先级信息由高层信令确定或由预设方式确定；或者，
在第一配置信息为调度时间间隔信息的情形下，传输信号对应的调度时间间隔越大，确定传输信号的优先级信息所指示的优先级越高；或者，
在第一配置信息为CC索引信息的情形下，传输信号对应的CC索引越小，确定传输信号的优先级信息所指示的优先级越高。
在一实施例中，本实施例中的空间参数确定方法还包括：
在传输信号没有关联的CORESET组或者CORESET的情形下，为传输信号确定关联的CORESET组或者CORESET。比如所述传输信号没有对应的CORESET组，那么默认所述的传输信号对应的CORESET组的索引为0；所述传输信号没有对应的CORESET，那么默认所述的传输信号对应的CORESET的索引为0。
在一实施例中，上述空间参数信息包括以下至少之一：
准共址参数；准共址参考信号；关联空间接收参数的准共址参考信号；空间发送滤波器；空间关系参考信号。
需要进一步说明的是，本发明实施例所述的空间参数确定方法，适用于前述第一通信节点和第二通信节点，第一通信节点通过本发明实施例中的方法确定的空间参数来发送所述的传输信号，比如确定发送所述传输信号所使用的发送波束。而第二通信节点可以用本发明实施例中的方法确定的空间参数来接收所述的传输信号，比如确定接收所述传输信号所使用的接收波束。
以下通过多个示例性实施例的方式进一步阐述本实施例中的空间参数确定方法：
示例实施例1
在一示例实施例中，包括至少一个第一通信节点，配置了N个CORESET组，每个CORESET组包括至少一个CORESET，相同CORESET组内的CORESET高层参数索引coresetPoolIndex-r16取值相同，那么可以根据CORESET组里的coresetPoolIndex-r16取值确定传输信号的优先级，比如调度传输信号对应的CORESET的coresetPoolIndex-r16取值越小，其对应的传输信号的优先级越高。另外一方面，可用CORESET组对传输信号进行分组，比如当调度传输信号对应的CORESET具有相同 coresetPoolIndex-r16取值，那么可以把它们分成同一个传输信号组。N为大于1的整数，不失一般性，这里假设N＝2，其中CORESET组1包括CORESET1和CORESET2，每个CORESET对应的coresetPoolIndex-r16取值为0，CORESET组2包括CORESET3和CORESET4，每个CORESET对应的coresetPoolIndex-r16取值为1；其中传输信号1和传输信号2分别使用CORESET组1里的CORESET1中的DCI1和CORESET组2里的CORESET3中的DCI3调度，如果DCI1对应的CORESET的COREST组索引coresetPoolIndex-r16取值为0，而DCI3对应的CORESET的COREST组索引coresetPoolIndex-r16取值为1，那么传输信号1的优先级比传输信号2的优先级高。
如果传输信号1和传输信号2分别使用CORESET组1里的CORESET1中的DCI1和CORESET组1里的CORESET2中的DCI2调度，由于DCI1和DCI2有相同的CORESET组索引的取值，那么传输信号1和传输信号2可以被分为同一个传输信号组。并需要根据CORESET索引、虚拟小区号信息、物理小区标识PCI信息、无线网络临时标识RNTI的类型信息、下行控制信息DCI的参数信息、调度时间间隔信息、信道类型信息、CC索引信息等至少之一确定其空间参数的优先级，并根据优先级确定传输所述传输信号组里的传输信号使用的空间参数。
根据上面的讨论，由于传输信号1的优先级高于传输信号2的优先级，所以确定传输信号1对应的空间参数为优选的空间参数，即如果传输信号1和传输信号2在相同的符号里传输，那么，优先使用传输信号1关联的空间参数为这个符对应的空间参数，用这个空间参数确定的波束来接收传输信号1和传输信号2。需要说明的是，最终接收传输信号的空间参数可能大于1个，那么是，即最终的所述空间参数为传输信号优先级高的K个传输信号对应的空间参数，或者为每个传输信号组里优先级高的Ki个传输信号对应的空间参数，Ki为正整数，为第i个传输信号组最大的空间参数个数，所有传输信号组的Ki之和小于K，i＝1，…，C，C为传输信号组的个数，所述K为大于等于1小于N的整数，K和Ki由高层信令配置 或UE能力确定。
示例实施例2
在一示例实施例中，包括至少一个第一通信节点，配置了N个CORESET，每个CORESET都有一个关于CORESET的索引controlResourceSetId用于标识所述的CORESET。那么可以根据CORESET的索引controlResourceSetId取值确定传输信号的优先级，比如调度的传输信号的DCI所对应的CORESET的controlResourceSetId取值越小，其对应的传输信号的优先级越高。另外，可以将controlResourceSetId索引分成多个controlResourceSetId集合，所述controlResourceSetId集合可以通过高层信令配置，或者按约定的方式形成，比如controlResourceSetId小于A1的为一个controlResourceSetId集合，而大于A1的为一个controlResourceSetId集合。而被调度的多个传输信号的DCI对应的CORESET索引在相同的controlResourceSetId集合，那么可以把它们分成同一个传输信号组。N为大于1的整数，不失一般性，这里假设N＝4，其中，即配置了CORESET1、CORESET2、CORESET3和CORESET4，其对应的CORESET索引取值分别为0-3。另外，当设置A1＝2时，使用CORESET1和CORESET2对应的DCI调度的传输信号为一个传输信号组，而使用CORESET3和CORESET4对应的DCI调度的传输信号为一个传输信号组。一个具体传输过程中，传输信号1和传输信号2分别使用CORESET1中的DCI1和CORESET3中的DCI3调度，因为DCI1对应的CORESET的COREST索引取值为0，而DCI3对应的CORESET的COREST索引取值为2，那么传输信号1的优先级比传输信号2的优先级高。
如果传输信号1和传输信号2分别使用CORESET1中的DCI1和CORESET2中的DCI2调度，由于DCI1和DCI2在相同的CORESET索引集合，那么传输信号1和传输信号2可以被分为同一个传输信号组，并且DCI1对应的CORESET索引小于DCI2对应的CORESET索引，所以传输信号1的空间参数优先级高于传输信号2的空间参数优先级，当然对 于同一组的传输信号也可以用第二配置信息中除了CORESET索引外的其它信息确定传输信号的优先级。
基于上述阐述，由于传输信号1的优先级高于传输信号2的优先级，所以确定传输信号1对应的空间参数为优选的空间参数，即如果传输信号1和传输信号2在相同的符号里传输，那么，优先使用传输信号1关联的空间参数为这个符对应的空间参数，用这个空间参数确定的波束来接收传输信号1和传输信号2。需要说明的是，最终接收传输信号的空间参数可能大于1个，那么是，即最终的所述空间参数为传输信号优先级高的K个传输信号对应的空间参数，或者为每个传输信号组里优先级高的Ki个传输信号对应的空间参数，Ki为正整数，为第i个传输信号组最大的空间参数个数，所有传输信号组的Ki之和小于K，i＝1，…，C，C为传输信号组的个数，所述K为大于等于1小于N的整数，K和Ki由高层信令配置或UE能力确定。
示例实施例3
在一示例实施例中，包括至少一个第一通信节点，第一通信节点可能同时传输多种业务类型，包括超高可靠与低时延通信(Ultra-reliable and Low Latency Communications，URLLC)业务与增强移动宽带(Enhanced Mobile Broadband，eMBB)业务。其中，URLLC和eMBB的优先级主要根据物理下行控制信息中的优先级指示PI(Priority indicator)信息指示，即下行控制格式0-1，0-2，1-1或1-2(DCI0_1或DCI0_2，DCI1_1或DCI1_2)中的Priority indicator域中的取值，DCI中PI值越大，表示所述DCI对应的传输信号的优先级越高，可以优先传输。比如，第一个传输信号对应的DCI的所述PI值为1时，而第二个传输信号对应的DCI的所述PI值为0时，第二个传输信号的优先级低于第一个传输信号的优先级。从而终端可以根据接收的PI指示确定eMBB和URLLC的优先级，并根据eMBB和URLLC的优先级确定传输信号的空间参数，比如如果PI指示eMBB的优先级高，那么跟eMBB相关的传输信号的优先级比跟URLLC相关的传输信号优先级高，否则跟eMBB相关的传输信号的优先级比跟URLLC相关 的传输信号优先级低。另外可以根据PI指示对传输信号进行分组，比如传输信号对应的PI值为1的传输信号为一组，传输信号对应的PI值为0的传输信号为一组。而相同组内的传输信号，通过CORESET组索引、CORESET索引、虚拟小区号信息、物理小区标识PCI信息、无线网络临时标识RNTI的类型信息、下行控制信息DCI的参数信息、调度时间间隔信息、信道类型信息、CC索引信息等至少之一确定传输信号组内的传输信号的优先级，并根据传输信号的优先级确定传输所述传输信号使用的空间参数，所述空间参数为传输信号优先级高的K个传输信号对应的空间参数，或者为每个传输信号组里优先级高的Ki个传输信号对应的空间参数，Ki为正整数，为第i个传输信号组最大的空间参数个数，所有传输信号组的Ki之和小于K，i＝1，…，C，C为传输信号组的个数，所述K为大于等于1小于N的整数，K和Ki由高层信令配置或UE能力确定。
示例实施例4
