在一实施例中，类似地，也可以采用上述方法建立探测参考信号(sounding reference signal，SRS)资源组和CORESET(或搜索空间集合)之间的对应关系，SRS资源组中的SRS资源的参数根据与其存在对应关系的CORESET(或搜索空间集合)的准共址参考信号获取，只是将上述方法中的PUCCH资源组替换为SRS资源组。其中SRS资源组包括如下之一：一个频域带宽中的一个SRS resource set；一个频域带宽组中的具有相同SRS resource索引的SRS resource构成的SRS resource组。所述SRS资源组中的SRS资源的参数包括如下之一：空间发送滤波器，空间关系信息中的参考信号，功率参数。或者是SRS资源组的参数根据与其存在对应关系的CORESET(或搜索空间集合)的准共址参考信号获取，其中SRS资源组的associated CSI-RS为所述CORESET(或搜索空间集合)的准共址参考信号，其中，CSI-RS，英文全称是Channel-State Information reference Signal，中文名称是信道状态信息参考信号。示例性地，比如SRS资源组包括一个SRS resource set，所述SRS resource set对应的associated-CSI-RS参考信号为CORESET(或搜索空间集合)的准共址参考信号，即此时比如这个SRS resource set的用途是non codebook，则这个SRS resource set中的不同SRS resource对应的发送波束可以不同，都是基于associated-CSI-RS得到的，比如不同SRS resource对应基于associated-CSI-RS得到的不同接收波束。或者终端基于associated-CSI-RS得到下行信道，根据上下行互易性进而得到上行信道矩阵，SRS resource set中的不同SRS resource对应基于此上行信道矩阵得到的不同上行数字预编码。
上述描述中,CORESET(或者搜索空间集合)的准共址参考信号即CORESET的解调参考信号的准共址参考信号。在一实施例中，上述PUCCH资源或SRS资源的参数根据CORESET(或者搜索空间集合)的 解调参考信号的关联预定准共址参数的准共址参考信号，比如预定准共址参数包括空间接收参数。

规则三：MAC-CE为预定频域带宽中的PDCCH激活的索引第i*L:(i+1)*L-1低的L个TCI state；
规则四：codepoint i对应的TCI state中的前L个TCI state；
规则五：对应的TCI state个数等于预定值(即所述第三预定值)的代码点(codepoint)中的最低codepoint对应的TCI state中的前L个TCI state,所述预定值为如下之一：2；L；为codepoint和TCI state之间的映射表格中一个codepoint对应的TCI state的最大个数，具体地，比如预定值为2，则TCI state为为表2中的codepoint 001对应的{TCI state0,TCI state6}中的前L个TCI state，或者为表3中的codepoint 000对应的{TCI state9,TCI state7}中的前L个TCI state；
其中所述codepoint为下行控制信息(Downlink Control Information，DCI)中TCI指示域对应的codepoint,如表2～3所示,所述codepoint和TCI state之间的映射关系对应PDSCH所在的频域带宽，即当PDCCH中包括 TCI指示域，所述PDCCH调度的PDSCH的TCI state根据所述映射关系和所述PDCCH中TCI指示域指示的codepoint得到。
其中L是PUCCH资源的空间发送滤波器的个数，或者空间关系信息的个数，L值根据配置或调度所述PUCCH资源的信令信息中指示的信息获取。
在一实施例中，通过信令信息确定PUCCH资源组对应的TCI state,其中所述信令信息包括RRC信令，MAC-CE信令中的一种或多种，比如通过所述信令信息配置所述PUCCH资源组对应的如下之一：
一:TCI state索引，这个TCI state索引是TCI state的绝对索引，即在RRC配置TCI state的时候为所述TCI state配置的索引,比如表2中的TCI state 8的索引为8；
二：为PDSCH激活的TCI state的索引，这个索引是相对索引，即在激活的TCI state集合中的索引，具体地，比如t1时刻，PDCCH中的TCI指示域中的codepoint和TCI state之间的映射关系如表2所示，则为PDSCH激活的TCI state集合为{TCI state 0,TCI state 1,TCI state 3,TCI state 6,TCI state 8,TCI state 10,TCI state 18,TCI state 64,TCI state 100,TCI state 124},如果RRC信令为PUCCH资源组配置的TCI state相对索引为4，则此PUCCH资源组对应的TCI state为TCI state 8，当t2时刻，MAC-CE将PDCCH中的TCI指示域中的codepoint和TCI state之间的映射关系更新为表3所示，则此PUCCH资源组对应的TCI state为TCI state6；
三：codepoint索引,codepoint为PDCCH的TCI指示域对应的codepoint,比如配置的codepoint为001，则t1时刻PUCCH资源组中的PUCCH资源的参数根据codepoint 001对应的{TCI state0,TCI state6}中的一个或者两个TCI state中的准共址参考信号获取，t2时刻则PUCCH资源组中的PUCCH资源的参数根据codepoint 001对应的{TCI state1,TCI state10}中的一个或者两个TCI state中的准共址参考信号获取。建立PUCCH资源组和codepoint索引之间的关系之后，codepoint对应的TCI state通过MAC-CE 更新之后，这个MAC-CE对应的ACK的3ms之后的第一个slot开始，所述PUCCH资源组中的PUCCH资源的参数，根据所述codepoint对应的更新后的TCI state获取，另一种方式是，只有这个codepoint被PDCCH指示用于一个PDSCH的传输之后，所述PUCCH资源组中的PUCCH资源的参数，根据所述codepoint对应的更新后的TCI state获取,否则虽然MAC-CE更新了此codepoint对应的TCI state,但是没有将此codepoint指示用于PDSCH的传输，则所述PUCCH资源组中的PUCCH资源的参数，根据所述codepoint对应的更新前的TCI state获取。或者除非此codepoint是上述规则五中的预定codepoint。

在一实施例中，PUCCH资源组中的PUCCH资源的参数根据TCI state中的参考信号获取。
在一实施例中，类似地，也可以采用上述方法建立SRS资源组和TCI state之间的对应关系，SRS资源组中的SRS资源的参数根据与其存在对应关系的TCI state的参考信号获取，只是将上述方法中的PUCCH资源组替换为SRS资源组。其中SRS资源组包括如下之一：一个频域带宽中的一个SRS resource set；一个频域带宽组中的具有相同SRS resource索引的SRS resource构成的SRS resource组。所述SRS资源组中的SRS资源的参数包括如下之一：空间发送滤波器，空间关系信息中的参考信号，功率参数。或者是SRS资源组的参数根据与其存在对应关系的TCI state的参考信号获取，其中SRS资源组的associatedCSI-RS为所述TCI state的参考信号。具体地，比如SRS资源组包括一个SRS resource set，所述SRS resource set对应的associated-CSI-RS参考信号为TCI state的参考信号，即此时比如这个SRS resource set的用途是non codebook，则这个SRS resource set中的不同SRS resource对应的发送波束可以不同，都是基于associated-CSI-RS得到的，比如不同SRS resource对应基于associated-CSI-RS得到的不同接收波束。或者终端基于associated-CSI-RS得到下行信道，根据上下行互易性进而得到上行信道矩阵，SRS resource set 中的不同SRS resource对应基于此上行信道矩阵得到的不同上行数字预编码。
在本文中所述代码点也可以称为TCI代码点，即PDCCH中的传输配置指示域TCI代码点。
上述是建立上行PUCCH资源组或SRS资源组和TCI state或TCI代码点之间的关系，类似地，也可以建立下行控制信道资源组和TCI state或TCI代码点之间的关系，其中下行控制信道资源组的准共址参考信号根据与其存在对应关系的TCI state或TCI代码点的准共址参考信号获取。MAC-CE更新了这些TCI state或TCI代码点,则下行控制信道资源组的准共址参考信号也跟着更新。其中下行控制信道资源组包括如下之一：一个频域带宽中的下行控制信道资源组，一个频域带宽组中的不同频域带宽中的具有相同下行控制信道资源索引的下行控制信道资源构成的下行控制信道资源组，其中下行控制信道资源包括如下之一：下行控制资源集合CORESET，搜索空间集合。
类似地，也可以建立上行数据信道PUSCH组和TCI state或TCI代码点之间的关系，比如在高层配置的PUSCH配置信息中，配置其对应的TCI state或TCI代码点。
示例实施方式三
P个PUCCH资源组中的P1个PUCCH资源组和CORESET存在对应关系，PUCCH资源组中的PUCCH资源的参数根据与其存在对应关系的CORESET的准共址参考信号获取，或者根据CORESET的TCI state中的参考信号获取，如示例实施方式一所示。
P个PUCCH资源组中的P2个PUCCH资源组和TCI state存在对应关系，PUCCH资源组中的PUCCH资源的参数根据与其存在对应关系的TCI state中的参考信号获取，如示例实施方式二所示。其中P1，P2是小于或等于P的正整数，或者P1+P2＝P。
类似地，S个SRS资源组中的S1个SRS资源组和CORESET存在对 应关系,S2个SRS资源组和TCI state存在对应关系。
通过上述方案，建立上行信道或信号组和下行信道或信号之间的对应关系，下行信道或信号的参数发生变化的情况下，与其存在对应关系的上行信道或信号的参数也发生变化，信令信息更新下行信道或信号的参数时，上行信道或信号的参数也一起更新，并且是以上行信道或信号组中的上行信道或信号的参数都改变，实现节省信令开销的同时，快速跟踪波束变化的目的，比如上述参数的变化就隐含反映波束的变化。
上述方案中，上行信道或信号的参数根据与其存在对应关系的下行信道或信号的准共址参考信号，与其存在对应关系的下行信道或信号的TCI state中的参考信号获取，在一实施例中，也可以所述下行信道或信号的准共址参考信号根据与其存在对应关系的上行信道或信号的参数获取。此时如果上行信道或信号的参数如果通过信令信息或预定规则更新，则与其存在对应关系的下行信道或信号的准共址参考信号也发生更新，从而就可以实现在节省信令的同时，快速跟踪波束变化，或其他参数变化。
示例实施方式四
在本实施例中，上行信道或信号的参数，根据下行信道或信号的准共址参考信号获取，上行信道或信号占有多个时间单元，在所述上行信道或信号占有的多个时间单元范围内，下行信道或信号的准共址参考信号发生了更新,即在上行信道或信号占有的多个时间单元中对应下行信道或信号的两份准共址参考信号信息，更新前的准共址参考信号信息，更新后的准共址参考信号信息，需要根据控制信息或预定规则在两份准共址参考信号信息中选择一个或者确定各个时间单元对应的准共址参考信号。如图6所示，上行信道或信号的参数根据所述上行信道或信号对应的服务小区中的具有最低CORESET索引的CORESET的准共址参考信号获取，比如根据CORESET0的准共址参考参考信号获取，而CORESET0的准共址参考信号通过MAC-CE更新，比如在slot(n-8)中终端收到包括该MAC-CE的PDSCH,CORESET0原来的TCI state为TCI state1，该MAC-CE将 CORESET0的TCI state更新为TCI state2，该MAC-CE更新的TCI state在slot(n+5)可用，上行信道或信号(比如图6中的PUCCH资源)在slot(n)～slot(n+7)上传输，在slot(n+5)之前CORESET0的TCI state是TCI state1,在slot(n+5)的时候，CORESET0的TCI state已经更新为TCI state2。即此时在PUCCH上行信道或信号所占的时域范围内，CORESET0有两个TCI state，需要确定PUCCH的参数根据TCI state1或还是TCI state2获取，比如根据TCI state1中的准共址参考信号得到上行信道或信号的空间发送滤波器为发送波束1，根据TCI state2中的准共址参考信号得到上行信道或信号的空间发送滤波器为发送波束2，此时需要确定上行信道或信号的发送波束是发送波束1或发送波束2。具体地可以采用如下方案中的一种或多种。
方案1：根据上行信道或信号所在的第一时间单元(比如第一个slot)中，下行信道或信号激活的TCI state确定上行信道或信号的参数,获取所述多个时间单元中每一个时间单元(即所述第二时间单元)中的上行信道或信号的参数，在所述多个时间单元中，所述上行信道或信号的参数相同，如图7所示，在一实施例中，终端希望其占有的多个时间单元上，CORESET0激活的TCI state是一样的。
方案2：根据上行信道或信号所在的时间单元(即所述第一时间单元)中，下行信道或信号激活的TCI state确定上行信道或信号的参数，获取所述多个时间单元中每一个时间单元(即所述第二时间单元)中的上行信道或信号的参数，如图8所示，在所述MAC-CE开始可用前的时间单元前采用更新前的TCI state,在所述MAC-CE开始可用开始的时间单元采用更新后的TCI state。
方案3：根据上行信道或信号所在的时间单元中，下行信道或信号激活的可用于TCI state确定上行信道或信号的参数,下行信道或信号的TCI state更新之后在X个时域符号后或Y个时间单元后可用于所述上行信道或信号的参数获取。在方案2中，X＝0,Y＝0,在方案3中，X,Y为大于或等于1的正整数。其中X,Y用于终端获取到下行接收波束，到终端根据所述 下行接收波束获取上行发送波束并采用所述上行发送波束发送所述上行信道或信号所需要的最小时间间隔，在一实施例中，终端可以X或Y值作为终端能力上报给基站。比如X属于{14,28,42},Y属于{1,2,3}。如图9～10所示，图9中X＝14,Y＝1，图10中X＝28,Y＝2。如果下行信道或信号的准共址参考信息通过MAC-CE更新，则此MAC-CE中包括的下行信道或信号的准共址参考信号信息在
Figure PCTCN2021083368-appb-000014
之后的第Y+1个slot可用于上行信道或信号参数的获取。
方案4：根据第一类时间单元个数和第二类时间单元个数的比例，确定是采用方案1还是方案2，第一类时间单元对应所述下行信道或信号的准共址参考信号信息更新之前的上行信道或信号的时间单元，第二类时间单元对应所述下行信道或信号的准共址参考信号更新之后(包括更新所在时间单元)的上行信道或信号的时间单元，当所述比例小于或等于1的情况下,采用方案2，当所述比例大于1，采用方案1，或者当所述比例小于或等于1，在所述上行信道或信号的前
Figure PCTCN2021083368-appb-000015
(或前
Figure PCTCN2021083368-appb-000016
)的时间单元中，所述上行信道或信号的参数，根据更新之前的TCI state获取，在所述上行信道或信号的剩余的时间单元中，所述上行信道或信号的参数，根据更新之后的TCI state获取,其中N是上行信道或信号所占的时间单元的个数。即当所述下行信道或信号的更新发生在
Figure PCTCN2021083368-appb-000017
(或
Figure PCTCN2021083368-appb-000018
)slot之前的时间单元中的情况下，可以采用方案2，或前
Figure PCTCN2021083368-appb-000019
(或前
Figure PCTCN2021083368-appb-000020
)的时间单元中，采用更新前的，其余的时间单元中采用更新后的，如图11所示。当所述下行信道或信号的更新发生在
Figure PCTCN2021083368-appb-000021
(或
Figure PCTCN2021083368-appb-000022
)slot之后的时间单元的情况下，采用方案1。如果下行信道或信号的准共址参考信息通过MAC-CE更新，则此MAC-CE中包括的下行信道或信号的准共址参考信号信息在
Figure PCTCN2021083368-appb-000023
之后的第一个slot可用(比如此时下行信道或信号的准共址参考信号就可以更新为MAC-CE中携带的TCI state中的准共址参考信号)，其中slot(k)是终端反馈针对包括所述MAC-CE的PDSCH的ACK所在的slot,
Figure PCTCN2021083368-appb-000024
是一个子帧中包括的slot个数，PUCCH的子载波间隔为15kHz*2 μ，即第一类时间单元包括上行信道或信号所占的多个时间单 元中落在预定时间单元之前的，其中预定时间单元包括
Figure PCTCN2021083368-appb-000025
之后的第一个slot，比如为图6中的slot(n+5))的时间单元,第二类时间单元包括预定时间都那样以及预定时间单元之后的时间单元。
方案5，根据第一时间单元最近的且包括CORESET0的时间单元中的CORESET0的准共址参考信号，确定PUCCH的参数。如图12所示，虽然在slot(n+4)中CORESET0的更新后的TCI state可用了，但是slot(n+4)上没有关联CORESET0的需要检测的搜索空间，在slot(n+4)之前，距离slot(n+4)且包括CORESET0的slot为slot(n)，slot(n)中CORESET0的可用TCI state为更新前的TCI state,所以从slot(n+6)开始，PUCCH基于CORESET0的更新后的TCI state获取PUCCH的参数。
类似地，上述预定时间单元(即所述第三时间单元)如果定为
Figure PCTCN2021083368-appb-000026
之后的第一个slot+Y个时间单元，则可以根据第一类时间单元个数和第二类时间单元个数的比例，确定是采用方案1还是方案3，只是把上述方案4中的方案2替换为方案3。
在一实施例中上行信道包括如下至少之一：PUCCH，PUSCH,上行信号包括SRS。
在一实施例中，上行信道或信号的参数包括如下至少之一：空间发送滤波器，空间关系参考信号，功率参数，传输模式，associated CSI-RS。
在一实施例中，所述功率参数包括所述上行信道或信号的路损参考信号。
在一实施例中，上行信道或信号的参数根据下行信道或信号的关联预定准共址参数的准共址参考信号获取，比如所述预定准共址参数包括空间接收参数。
在图6～图12中，更新前和更新后CORESET0的TCI state的个数都为1个，在一实施例中，更新前和更新后的CORESET0的TCI state的个数都为2个,如图13～15,此时PUCCH资源在8个slot中重复传输，CORESET0的2个TCI state在每隔2个slot更换一次，但是在如图13～15 所示，MAC-CE的更新信令在slot(n+5)生效，slot(n+5)属于2个slot为一组的slot组后一个slot中，此时如果采用上面的方案2，就可以采用图13～15中之一处理。图13中更新后的TCI state在可用slot之后第一组slot开始用于PUCCH资源的参数获取，即只在一组slot的第一个slot中切换PUCCH的参数所采照的CORESET0的准共址参考信号信息，图14中，如果第二类时间单元中的3个slot都用更新后的第一个TCI state,TCI state2。图15中更新后的TCI state在可用slot就开始用于PUCCH资源的参数获取,下一个slot组TCI state发生切换。图16中，更新前是2个TCI state，更新后是1个TCI state。或者将8个slot(即所述N个时间单元)分成多个组，比如以2个slot为一个组，根据每个组中的第一个时间单元中可用的CORESET0的准共址参考信号获取PUCCH的参数，或者所述PUCCH资源的参数只在所述一个时间单元组的第一个时间单元才会在CORESET0的新旧准共址参考信号信息之间切换，在其他时间单元不切换，即比如所述CORESET0的更新的准共址参考信号在一个时间单元组的非第一个时间单元开始可用，则这个时间单元组都用CORESET0的更新前的准共址参考信号，所述CORESET0的更新的准共址参考信号在一个时间单元组的第一个时间单元开始可用，则这个时间单元组都用CORESET0的更新后的准共址参考信号进一步限定N个时间单元中最多对应CORESET0的2份(即所述E值)准共址参考信号信息，即在N个时间单元中CORESET0的,上述实施例中一个时间单元为一个slot,当然本实施例也不排除一个时间单元为如下之一：子时间单元sub-slot,子帧等。
图6中是通过MAC-CE更新下行信道或信号的准共址参考信号，本实施例的另一种方式是通过预定规则确定下行信道或信号的准共址参考信号，比如CORESET0的准共址参考信号根据终端最近发送的PRACH时，PRACH对应的下行参考信号获取,或者CORSET0的准共址参考信号和下行同步信号之间存在对应关系。或者通过PDCCH更新了下行信道或信号的准共址参考信号，PDCCH更新的下行信道或信号的准共址参考信号在所述上行信道或信号所占的多个时间单元中的其中一个时间单元可 用。
上述方案1～4是上行信道或信号的参数根据CORESET(Control resource set)的准共址参考信号获取的例子，类似地，上述方案也适合所述上行信道或信号的参数根据TCI state获取的场景，其中TCI state可以为示例实施方式二中描述的TCI state。当MAC-CE更新了PDSCH的TCI state的情况下，也会发生图6的情况。
或者上述方案也适应于MAC-CE直接更新上行信道或信号的参数的场景。具体地，比如通过MAC-CE更新了PUCCH的空间关系信息，所述PUCCH在8个slot中重复发送，MAC-CE在PUCCH所占的8个slot中其中一个slot开始可用(即针对包括MAC-CE的PDSCH的ACK之后的3ms落在所述8个slot中的其中一个slot)，即在PUCCH所占的8个slot范围内，PUCCH的空间关系对应两份可用的配置，需要确定所述PUCCH的需要采用哪一份配置。特别是两份配置中的其中一份或两份包括2个以上的空间关系信息，所述2个以上(包括2个)的空间关系分别对应PUCCH的不同的资源，其中所述资源包括如下之一：频域资源，时域资源，解调参考信号资源,其中每个空间关系信息中包括一个参考信号，PUCCH的发送波束。
类似地，上述方案1～4也适应于如下场景，一个信道或信号占有多个时间单元，在所述多个时间单元中的其中一个时间单元中信道或信号的参数发生了更新，比如基站通过MAC-CE更新所述参数，所述MAC-CE中的信息在所述多个时间单元中的其中一个时间单元中开始可用，需要确定在所述多个时间单元中的每个时间单元中，所述信道或信号的参数是用更新前的还是更新后的。
具体地，比如MAC-CE更新了PUSCH的参数，在PUSCH所占的多个时间单元中的其中一个时间单元中，所述MAC-CE中指示的信息开始可用。可以采用上述方案1～4中的任意一个来确定PUSCH的各个时间单元中，所述PUSCH的参数是更新前的还是更新后的。或者当上行信道为 PUSCH的时候，采用方案1，PUCCH的时候采用方案2，因为PUSCH有MCS,更新前的TCI state和更新后的TCI state采用同一个MCS可能不合适，但是PUCCH没有MCS,所以采用方案2或方案3。
或者MAC-CE更新了下行控制信道资源的TCI state,在下行控制信道资源所占的多个时间单元中的其中一个时间单元中，所述MAC-CE中指示的信息开始可用。可以采用上述方案1～5中的任意一个来确定PDCCH的各个时间单元中，所述PUSCH的路损参考信号是更新前的还是更新后的。其中所述下行控制信道资源包括如下之一：CORESET,搜索空间，候选控制信道。
在一实施例中，上述时间单元包括如下之一：子时隙sub-slot,时隙slot,子帧等,MAC-CE开始可用的时间单元，比如所述MAC-CE在终端发送了针对包括MAC-CE的PDSCH的ACK之后C个时间单元可用，此处的时间单元是什么，则上述时间单元就是什么。
示例实施方式五
如图17所示，在通过MAC-CE命令更新非周期性探测参考信号(AP-SRS)resource set中的SRS资源的空间关系参考信号，在所述MAC-CE中有一个S域，所述S域指示AP-SRS set中的不同AP-SRS资源的空间关系参考信号所在的服务小区和BWP是否共享。当S域指示共享时，AP-SRS set中的不同AP-SRS资源的空间关系参考信号所在的服务小区和BWP共享,则此MAC-CE中包括的内容如图18所示，即所述AP-SRS资源集合中的不同AP-SRS资源的空间关系参考信号位于同一服务小区和BWP，不共享的时候，如图17所述。进一步地，所述S和C域可以联合编码，C是指示MAC-CE是否包括空间关系参考信号的频域带宽信息。
示例实施方式六
基站给终端分配多于一个的SRS resource set，其中所述SRS resource set的用途是non codebook，这多于一个SRS resource set中的不同SRS  resource set中的SRS resource终端不能同时发送，属于同一个SRS resource set的SRS resource可以同时发送最多G个，其中G是终端能力。
在一实施例中，所述多于一个的non codebook SRS resource set的时域特性相同，其中时域特性包括如下之一：非周期，周期，半持续。
在一实施例中，所述多于一个的non codebook SRS resource set中的SRS resource的端口号根据所述SRS resource的所在的SRS resource set索引和其在所在的SRS resource set中的相对索引获取。比如第j个non codebook SRS resource set中的第i个SRS resource的端口号为：1000+i+j*F,其中F为预定值，比如为一个non codebook SRS resource set中包括的最大SRS资源数，比如为4，或者第j个non codebook SRS resource set中的第i个SRS resource的端口号为
Figure PCTCN2021083368-appb-000027
其中F l是第l个non codebook SRS resource set中SRS resource的个数。
在一实施例中，所述多于一个的non codebook SRS resource set中的associatedCSI-RS关联相同的下行参考信号。
在一实施例中，所述多于一个的non codebook SRS resource set位于一个频域带宽，比如一个服务小区，或一个BWP中。即关联相同associatedCSI-RS的多个non codebook SRS resource set中，属于不同non codebook SRS resource set不能同时发送，属于不同non codebook SRS resource set的SRS resource可以同时发送。
本公开实施例通过为上行目标元素组和下行信道元素建立对应关系，下行信道元素的准共址参考信号更新之后，上行目标元素组中的上行目标元素的空间发送滤波器跟着发生改变，在节省信令开销的同时，达到快速跟着波束的目的。
一个信道或信号占有多个时间单元，在所述多个时间单元中的一个时间单元中所述信道或信号对应的参数发生了更新，需要确定所述信道或信 号的各个时间单元中所述信道或信号的参数根据更新前的还是更新后的参数确定，通过本公开实施例中的方案可以确定所述信道或信号的各个时间单元中所述信道或信号的参数根据更新前的还是更新后的参数确定。
