在一实施例中，第二类元素满足如下条件：第二类元素包括第二参数的个数M大于或等于N值的元素中满足预定特征的元素
例如：当N和M相等的时候，根据第二类元素的M个第二参数获取第一类元素的N个第一参数，如果此时N，M大于1，则需要规定N个第一参数和M个第二参数之间的对应关系，从而索引为i的第一参数根据与其对应的第二参数获取。
当N和M不相等的时候，需要确定第一类元素的第一参数的获取方法，为此可以采用如下方案中的一种或多种获取：
方案1：收发双方预定(比如终端和基站预定)，当第一类元素的第一参数根据第二类元素的第二参数获取的时候，N小于或者等于M，第一类元素的索引为i的第一参数根据第二类元素的索引为i的第二参数获取，其中i＝0,1,...,M-1或i∈{0,1,...,M-1}。或者通过信令信息或预定规则建立第一类元素的N个第一参数和第二类元素的M个第二参数之间的对应关系，索引为i的第一参数根据与其存在对应关系的第二参数获取。
方案2：N大于M的时候，根据多于一个的第二类元素的第二参数获取第一类元素的第一参数。例如根据
Figure PCTCN2021072406-appb-000001
个第二类元素的第二参数获取第一类元素的第一参数。其中
Figure PCTCN2021072406-appb-000002
表示N/M向上取整。可选地，将
Figure PCTCN2021072406-appb-000003
个第二类元素的第二参数，先令第二类元素索引不变，第一参数索引递增，然后再将第二类元 素索引递增的顺序，得到
Figure PCTCN2021072406-appb-000004
个第二参数，然后根据索引为j的第二参数得到第一类元素的索引为j的第一参数，j＝0,1,...,N-1。或者建立第一参数和第二参数之间的对应关系，索引为j的第一参数根据与其存在对应关系的第二参数获取。上述是假设多个第二类元素中每个第二类元素的第二参数的个数都为M，本实施例也不排除各个第二类元素的个数不同的情况。比如N＝2，M＝1，根据两个第二类元素的第二参数得到一个第一类元素的2个第二参数，其中第一类元素的索引为p的第一参数根据索引为p的第二类元素的第二参数获取，p＝1,2。或者N＝4，M＝2，根据两个第二类元素的第二参数得到一个第一类元素的4个第二参数，其中按照[索引为0的第二类元素的索引为0的第二参数，索引为0的第二类元素的索引为1的第二参数，索引为1的第二类元素的索引为0的第二参数，索引为1的第二类元素的索引为1的第二参数]的顺序得到4个第二参数的索引，然后索引为j的第一参数根据索引为j的第二参数获取，其中，j＝0,1,2,3。
可选地，多于一个第二类元素包括多于一个组中的第二类元素。或者多于一个第二类元素属于同一个第二类元素组。
可选地，可以通过信令信息或预定规则得到，多于一个第二类元素包括多于一个组中的第二类元素，还是多于一个第二类元素属于同一个第二类元素组。
可选地，第二类元素组根据如下方式之一获取：通过信令信息通知第二类元素组包括的第二类元素；一个第二类元素组中的第二类元素关联相同的组信息；一个第二类元素组中的第二类元素占有的时域资源和/或频域资源满足预定特征，根据调度第二类元素的控制信道的组信息确定第二类元素的组信息。比如落在一个时间单元中的第二类元素构成一个组，落在相同频域资源组中的第二类元素构成一个组。
方案3：N大于M的时候，第一类元素的M个第二参数根据第二类元素的M个第二参数获取，第一类元素其余的N-M个第二参数根据第三参数，其中第三参数根据信令信息或预定规则得到。
可选地，第三参数和第二类元素之间不存在对应关系。或第三参数对应第三类元素，其中第三类元素和第二类元素是不同的元素，或不同类型的元素。比如第二类元素是控制信道，第三类元素是数据信道。
方案4：N小于M的时候，根据信令信息和/或预定规则，确定第一类元素的N个第一参数根据第二类元素的M个第二参数中的N个第二参数获取，比如根据第二类元素中的前N个第二参数获取第一类元素的N个第一参数。比如索引为j的第一参数根据索引为j的第二参数获取，j＝0,1,...,N-1。
方案5：终端和基站约定，当第一类元素的第一参数根据第二类元素的第二 参数获取的时候，N小于或等于M min，其中，M min包括如下之一：一个第二类元素的第二参数的最小个数；一段时间内，所有第二类元素的第二参数构成的集合中，不同第二参数的总个数的最小值；一段时间内，一个频域带宽中所有第二类元素的第二参数构成的集合中，不同第二参数的总个数的最小值。
方案6：终端和基站约定，当第一类元素的第一参数根据第二类元素的第二参数获取的时候，N小于或等于M max，其中M max包括如下之一：一个第二类元素的第二参数的最大个数；一段时间内，所有第二类元素的第二参数构成的集合中，不同第二参数的总个数的最大值；一段时间内，一个频域带宽中所有第二类元素的第二参数构成的集合中，不同第二参数的总个数的最大值。
方案7：N大于M的时候，第一类元素的M个第一参数根据第二类元素的M个第二参数获取，第一类元素其余的N-M个第一参数根据M个第二参数中满足预定特征的一个第二参数获取，比如第一类元素其余的N-M个第一参数根据M个第二参数中索引最大的第二参数获取。或者第一类元素其余的N-M个第二参数根据M个第二参数中索引最小的第二参数获取。也即将N-M个第一参数对应的第四参数合并为一个第四参数，合并后的第四参数对应的第一参数根据M个第二参数中的索引最大(或最小)的第二参数获取。此时也可以称为N根据M获取。
方案8：N大于M的时候，第一类元素的N个第一参数重新进行划分，形成M个第四参数，然后第一类元素的M个第四参数对应的N个第一参数根据第二类元素的M个第二参数获取。此时也可以称为N根据M获取。
方案9：N小于或者等于M的时候，根据第二类元素的第二参数获取第一类元素的第一参数，N大于M的时候，根据第三类元素的第三参数获取第一类元素的第一参数。
上述方案中，N是配置或调度第一类元素的信令信息中通知的，如果采用上述方案1，5，6，7，8也可以称为N根据M获取，此时在配置或调度第一类元素的信令信息中可以不配置N值。
可选地，第一类元素的N个第一参数对应第一类元素的N个第四参数，其中第四参数包括如下至少之一：解调参考信号(Demodulation Reference Signal，DMRS)端口组，时域资源组，频域资源组，第一类元素的传输机会。比如N个第一参数对应N个DMRS端口组，每个DMRS端口组对应一个第一参数，N个DMRS端口组对应信道占有相同的时频资源，如图2所示，图2为2个第一参数TCI state对应2个DMRS端口组的示意图。在图2中，多个预编码资源块组(Pre-coding RB Group，PRG)得到2个第一参数，TCI1和TCI2，其中TCI为传输配置指示(Transmission Configuration Indication)，2个第一参数对应2 个DMRS端口组。
或N个第一参数对应N个资源组，每个资源组对应一个第一参数。一个第一参数对应的资源组中包括的资源可以是连续的资源，或非连续的资源，N个资源组对应第一类元素的至少N次重复传输，即一个资源组可能包括第一类元素的一次或多次重复传输，或者多个资源组包括第一类元素的一次传输机会，其中资源包括时域资源和频域资源中的一种或多种。比如资源组是时域资源组，如图3和图4所示，图3为一个时隙(slot)内两处重复传输对应不同TCI的示意图，图4为4个slot中的4次重复传输和2个TCI之间的映射关系的示意图。图3中2个第一参数TCI状态(TCI state)(即图中的TCI)对应一个slot中的2个时域资源组，图4中2个第一参数TCI state对应4个slot中的2个时域资源组，TCI state1(即图4中的TCI1)对应的时域资源组为{传输机会1，传输机会2}，TCI state2(即图4中的TCI2)对应的时域资源组为{传输机会3，传输机会4}，其中信道在多个传输机会中重复传输。
比如资源组是频域资源组，图5为2个频域资源对应2个TCI的示意图。2个TCI state对应2个频域资源组，如图5所示，TCI state1(即图5中的第一TCI state)对应的频域资源组为{PRG1,PRG3}，TCI state2(即图5中的第二TCI state)对应的频域资源组为{PRG2,PRG4}，其中PRG(Precoding Resource block Group)为预编码资源块组，相同PRG中的信道的预编码相同，不同PRG中信道的预编码相同或不同。
本申请实施例也不排除一个第二参数对应多于一个的第一参数，比如图2中的一个DMRS端口组对应2个TCI state，此时图2中的2个DMRS端口组就对应4个TCI state，或者图3～图4中的一个时域资源组中的每个时域资源上对应2个TCI state，从而会导致图3～图4中的2个时域资源组总共对应4个第TCI state。或者图5中的一个频域资源组中每个频域资源上对应2个TCI state，从而会导致图5中的2个频域资源组总共对应4个TCI state。在上述图4的描述中，{传输机会1，传输机会2}对应的时域资源称为一个时域资源组，如果上述第四参数为传输机会的时候，传输机会1和传输机会2对应2个时域资源组，所以此时就是第一类元素的N个第一参数对应第一类元素的至少N个第四参数，每个第一参数对应一个或者多个第四参数，每个第四参数对应一个或者多个第一参数。
类似地，第二类元素的M个第二参数对应第二类元素的M个第四参数。比如M个第二参数对应M个DMRS端口组，每个DMRS端口组对应一个第二参数。或M个第二参数对应M个资源组，每个资源组对应一个第二参数。一个第二参数对应的资源组中包括的资源可以是连续的资源，或非连续的资源，M个 资源组对应第二类元素的至少M次重复传输，即一个资源组可能包括第二类元素的一次或多次重复传输，或者M个频域资源组对应第二类元素的一次重复传输，其中资源包括时域资源和频域资源中的一种或多种。本实施例也不排除一个第四参数对应多于一个的第二参数，一个第二参数对应一个或者多个第四参数。
可选地，第一类元素的N个第一参数中的每个第一参数在N个第一参数中的索引根据第一类元素对应的N个第四参数获取。比如N个第一参数对应N个时域资源组，则N个第一参数中的每个第一参数在N个第一参数中的索引根据该第一参数对应的时域资源组在N个时域资源组中的索引获取。比如第j个时域资源组对应的第一参数的索引为j，其中j＝0,1,...,N-1。可选地，N个时域资源组中的时域资源组的索引可以根据N个时域资源组中包括的起始时域符号的时域位置顺序得到，起始位置越后的时域资源组的索引越大。

可选地，上行元素包括上行信道或信号，比如包括PUCCH，PUSCH，SRS，物理随机接入信道(Physical Random Access Channel，PRACH)，或上行元素包括PUSCH的SRI映射表格的一项。
可选地，下行元素包括下行信道或信号，比如CORESET，PDSCH，信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)，同步信号和物理广播信道(Physical Broadcast Channel，PBCH)块(Synchronization Signal and PBCH block，SSB)，或下行元素包括TCI state映射表格中的一项。
可选地，上行元素的第一参数根据下行元素的第二参数获取包括如下场景中的一种或多种：
场景一-1：，上行元素的第一参数根据下行带宽中CORESET标识 (CORESET-ID)最低的CORESET(即第二类元素)的第二参数获取，如图6所示，图6为一个PUCCH的2个时域资源上空间滤波器信息分别根据一个CORESET中的2个频域资源上的TCI获取的示意图，PUCCH1的第一参数根据CORESET1的第二参数获取，其中PUCCH1的第一参数的个数N为2，对应PUCCH1的2个时域资源组，2个时域资源组分别在slot(n)和slot(n+1)中，CORESET1的第二参数的个数M为2，对应CORESET1的不同频域资源。可选地，上行元素所在的上行频域带宽对应的下行频域带宽中，配置了CORESET(Control Resource Set，控制资源集合)。
场景一-2：根据调度上行元素的PDCCH所在的CORESET(即第二类元素)的第二参数获取上行元素的第一参数，其中上行元素(即第一类元素)有对应的调度它的PDCCH。
场景一-3：上行元素的第一参数根据预定TCI state(即第二参数)获取，其中预定TCI state(即第二参数)包括如下之一：下行频域带宽中的PDSCH配置或激活的TCI state集合中，TCI state索引最低的一个或者多个TCI state；一个或者多个codepoint对应的TCI state，其中一个codepoint对应一个或者多个TCI state(即M个TCI state)，此时M等于一个codepoint对应的TCI state的个数，codepoint是TCI state映射表格中的codepoint，TCI state映射表格是MAC-CE为该下行频域带宽的PDSCH激活的TCI state映射表格，映射表格是DCI中的TCI指示域codepoint和TCI state之间的映射关系，如表1所示，其中codepoint对应DCI中TCI指示域的比特域值。此时将TCI state映射表格称为是PDSCH(即第二类元素)的参数，PDSCH基站可能没有发送，如果PDSCH发送，PDSCH的TCI state参数就可以根据TCI state映射表格和DCI中指示的TCI指示域获取，此时第一类元素的第一参数根据第二类元素的第二参数获取也可以称为第一类元素的第一参数根据第二参数获取。可选地，此时上行元素所在的上行频域带宽对应的下行频域带宽中，没有配置CORESET。
场景一-4：PUSCH的SRI映射表格中的一项对应的空间参数根据PDSCH的TCI state映射表格中的一项对应的TCI state获取。如表2或表3中一个SRI codepoint对应的空间关系信息根据表1中的一个TCI state copepoint对应的TCI state获取。即比如基站不通过信令通知表2或表3的SRI映射表格关系，而是只通过信令信息建立表1的映射关系，然后根据表1建立表2(或表3)，比如表1中codepoint对应的TCI state个数等于1的codepoint中前4个构成DMRS层数等于1的SRI映射表格，如表4所示，当SRI指示为1层且SRI codepoint值等于00，则PUSCH的空间参数根据TCI state1中包括的准共址参考信号获取，可选地根据TCI state1中关联空间接收参数的准共址参考信号获取。表1中codepoint对应的TCI state个数等于2的codepoint中前2个构成DMRS层数等 于2的SRI映射表格，如表5所示。

场景一-5：上行元素的第一参数根据PDSCH的第二参数获取，可选地，当第二参数是准共址参数且调度PDSCH的PDCCH和PDSCH之间的时间间隔小于预定阈值的情况下，PDSCH的第二参数不是根据调度PDSCH的PDCCH中指示的第二参数获取的，而是根据如下三种准共址参数之一获取调度间隔小于预定值的PDSCH的准共址参数：
信息一：距离PDSCH最近的slot中的关联检测搜索空间的CORESET中的具有最低CORESET-ID的CORESET的准共址参数；信息二：TCI state映射表格中对应的TCI state个数为2的codepoint中的最低codepoint；信息三：距离PDSCH最近的slot中的关联检测搜索空间且属于预定CORESET组的CORESET中具有最低CORESET-ID的CORESET的准共址参数。
可选地，采用上述三种信息中的哪一种获取调度间隔小于预定值的PDSCH的准共址参数根据CORESET组个数和TCI state映射表格中一个codepoint对应的TCI state的最大个数z确定，当CORESET组个数为2的时候，则采用信息三，当CORESET组个数为1且z值等于1则采用信息一，当CORESET组个数为1且z值大于1则采用信息二。但是此时调度PDSCH的PDCCH中也会指示准共址参数，只是这个准共址参数不用于PDSCH的接收，我们称PDCCH中指 示的准共址参数为信息四。可选地，上行元素的第一参数根据PDSCH的第二参数获取且第二参数包括准共址参数的情况下，此时需要确定上行元素的第一参数是根据上述信息一～信息四中哪一个获取。一种方式是PDSCH的接收采用信息一～信息三中的哪一个，则上行元素的第一参数根据哪一个获取，另一种方式是不管PDSCH的接收采用信息一～信息三中的哪一个，上行元素的第一参数都是根据信息四获取的。
在表4和表5中，TCI state的个数等于PUSCH的DMRS的层数，每个TCI state对应一个DMRS层，此时SRI映射表格中的一项(即表4-表5中的一行)对应空间参数的个数N通过DMRS的层数表示，即第一参数的个数N等于DMRS层数。在本实施例中也不排除N等于PUSCH的DMRS组的个数，一个DMRS组中的DMRS根据同一个TCI state获取其空间信息。可选地，DMRS组的个数根据基站通知的信令信息获取，或者根据DMRS所在的码分复用(Code Division Multiplexing，CDM)组的信息获取，此时第一参数的个数N等于DMRS端口组的个数。可选地，此时PDSCH和PUSCH共用一张表格如表1所示，或者PUSCH采用表1中的前预定个数项。
如果采用方案1，在场景一-1中就要求上行元素的第一参数个数N小于或者等于上述下行频域带宽中具有最低CORESET-ID的CORESET(即第二类元素)的第二参数的个数M。或者将场景一-1改为如下规则：要求上行元素的第一参数根据下行频域带宽中满足预定特征的CORESET集合中具有最低CORESET-ID的CORESET(即第二类元素)的第二参数获取，预定特征包括CORESET的第二参数大于或者等于N。如图7所示，图7为PUCCH的空间滤波器信息根据CORESET获取的示意图，CORESET1的第二参数个数为1，CORESET2的第二参数的个数为2，如果PUCCH的第一参数个数N为1，则PUCCH的第一参数根据CORESET1的第二参数获取，如果PUCCH的第一参数个数N为2，则PUCCH的第一参数根据CORESET2的第二参数获取，即此时CORESET索引最低且第二参数个数大于或者等于2的CORESET为CORESET2，而不是CORESET1。
在场景一-2中，要求调度上行元素的PDCCH所在的CORESET的第二参数的个数M大于或者等于上行元素的第一参数的个数N。
在场景一-3中，要求一个codepoint对应的TCI state的个数M大于或者等于上行元素的第一参数的个数N。
在场景一-4中，上行元素的DMRS层数N(或DMRS组的个数N)小于或等于一个codepoint对应的TCI state的个数M。
如果采用方案2，在场景一-1中，此时多于一个的下行元素包括关联多个 CORESET组的下行元素。比如根据多个CORESET组中的CORESET的第二参数获取上行元素的第一参数。如图8所示，图8为一个PUCCH的不同时域资源上的空间滤波器信息分别根据不同CORESET组中的最低CORESET获取的示意图，一个PUCCH的不同时域资源组对应不同的第一参数，其中第一时间资源组的第一参数根据CORESET组1中的最低CORESET的第二参数获取，第二时间资源组的第一参数根据属于CORESET组2中的最低CORESET的第二参数获取。或者此时多于一个的下行元素包括关联同一个CORESET组的多个下行元素。比如根据同一CORESET组中的多个CORESET的第二参数获取上行元素的第一参数。如图9所示，图9为一个PUCCH的不同时域资源上的空间滤波器信息分别根据一个CORESET组中的最低2个CORESET获取的示意图，一个PUCCH的不同时域资源对应不同的第一参数，其中第一时间资源的第一参数根据CORESET组1中的最低CORESET的第二参数获取，第二时间资源的第一参数根据CORESET组1中的次低CORESET的第二参数获取。
可选地，多于一个的下行元素包括关联多个CORESET组的下行元素还是包括同一个CORESET组的多个下行元素，可以根据信令信息或者预定规则得到。即是以图8的方式获取PUCCH的第一参数，还是以图9的方式获取PUCCH的第一参数，可以根据信令信息或者预定规则得到，比如一个CORESET组的时候就以图9的方式获取，两个CORESET组的时候就以图8的方式获取。
在场景一-2中，此时调度上行元素的PDCCH关联多个CORESET，或者多个CORESET中都包括调度上行元素的PDCCH，比如一个PDCCH在多个CORESET中重复传输，或多个CORESET分别包括调度上行元素的PDCCH的一部分。可选地多个CORESET属于一个CORESET组，或者要求多个CORESET包括属于不同CORESET组的CORESET，根据信令信息或预定规则确定多个CORESET属于一个CORESET组还是多个CORESET组。
在场景一-3中，此时基于多于一个codepoint对应的TCI state获取上行元素的第一参数，可选地，多于一个codepoint对应同一个TCI state映射表格，比如是一个TCI state映射表格的最低和次低codepoint，或者多于一个codepoint包括对应不同TCI state映射表格的codepoint，其中不同TCI state映射表格分别对应同一个频域带宽的不同CORESET组，比如多于一个的codepoint包括每个TCI state映射表格中的最低的一个或者多个codepoint。
在场景一-4中，DMRS的层数N(或DMRS端组个数N)大于一个codepoit对应的TCI state的个数的情况下，和场景一-3类似，此时基于多于一个codepoint对应的TCI state获取上行元素的第一参数。
如果采用方案3，上行元素的N个第一参数中M个第一参数根据第二类元 素的M个第二参数获取，上行元素的N个第一参数中其余N-M个第一参数根据第三参数获取，其中第三参数包括RRC信令或MAC-CE信令或DCI信令配置的参数，其中第三参数是专有参数，比如为上行元素的N-M个第一参数专门配置的参数，或者第三参数和第二类元素之间存在对应关系，上述上行元素的N个第一参数中的M个第一参数根据哪个第二类元素的第二参数获取，则N-M个第一参数就根据哪个第二类元素对应的第三参数获取，其中第二参数是第二类元素的传输参数，而第三参数不是第二类元素传输所需要的参数，比如在场景一-1和场景一-2中，第二参数和CORESET的DMRS之间存在准共址关系，但是第三参数和CORESET的DMRS之间没有准共址关系的限定。
或者第三参数为MAC-CE激活的参数，比如第三参数包括预定TCI state，其中预定TCI state包括如下之一：为下行频域带宽中的PDSCH配置或激活的TCI state集合中，TCI state索引最低的一个或者多个TCI state；TCI state映射表格中的一个或者多个codepoint对应的预定项TCI state。可选地，下行频域带宽包括上行元素所在的上行频域带宽对应的下行频域带宽。比如N＝2，M＝1，PUCCH(即上行元素)的2个第一参数中的1个第一参数根据上述第二类元素的第二参数获取，PUCCH的另一个第一参数根据PDSCH的TCI state映射表格中预定项codepoint中包括的预定项TCI state获取，其中预定项TCI state包括预定项codepoint中包括的多个TCI state中的预定项获取，比如预定项TCI state包括预定项codepoint中包括的多个TCI state中的第二个TCI state获取，假设PDSCH的TCI state映射表格如表6所示，预定项codepoint包括如下之一：
A.最低codepoint，即值为0的codepoint，比如表1中的codepoint‘00’，上行元素的另一个第一参数根据codepoint‘00’对应的第二个TCI state获取，即根据根据TCI state 2获取。
B.根据TCI state映射表格中满足预定特征的codepoint中的最低codepoint，预定特征codepoint包括codepoint中包含第二类元素的1个第二参数中的codepoint，比如第二参数为TCI state 1，则首先寻找TCI state映射表格中包括TCI state 1的codepoint，如表1所示，有codepint‘10’和’11’，然后取这2个中的最低，即codepoint‘10’。
C.根据TCI state映射表格中满足预定特征的codepoint中的最低codepoint，预定特征codepoint包括codepoint中对应的TCI state的个数满足预定特征，比如TCI state的个数大于1，则首先寻找TCI state映射表格中对应的TCI state个数大于1的codepoint，如表1所示，有codepint‘00’,’10’,’11’，然后取这3个中的最低，即codepoint‘00’。

找到上述预定项codepoint之后，根据上述codepoint对应的TCI state中的第二项TCI state(即预定项TCI state)获取第一参数，如果此时预定项codepoint中不包括预定项TCI state，如果上述codepoint‘00’或codepoint‘10’对应的TCI state个数为1，则上行元素的N-M个第一参数对应的第四参数部分不发送，比如N个第一参数对应N个时域资源组，就不发送上行元素后N-M个时域资源组。或者上行元素的N-M个第一参数都根据M个第二参数中的索引最大(或最小的)的第二参数。或者将N个第一参数对应的第四参数划分为M个第四参数，每个第四参数对应的第一参数分别根据M个第二参数中的一个第二参数获取获取。比如N个第一参数对应N个时域资源组，则此时将N个时域资源组划分为M个时域资源组。
如果采用方案4，比如N＝1，M＝2，1个第一参数对应1个DMRS端口组(或1个DMRS端口)，2个第二参数对应2个频域资源组，则1个第一参数根据2个频域资源中索引为0的频域资源组对应的第二参数获取。
如果采用方案5，在场景一-1或场景一-2中，如果一个CORESET的第二参数的个数最小值为1，则要求上述上行元素(即上述第一类元素)的第一参数的个数N小于或等于1；在场景一-3中，如果一个TCI state映射表格中的一个codepoint对应的TCI state个数的最小值为1，则要求上述上行元素(即上述第一类元素)的第一参数的个数N小于或等于1。
