相关申请的交叉引用
本申请主张在2021年10月27日在中国提交的中国专利申请号202111258237.6的优先权，其全部内容通过引用包含于此。
技术领域
本申请涉及通信技术领域，尤其涉及一种波束应用时间(beam application time，BAT)确定方法及用户设备。
背景技术
网络侧设备可以通过媒体接入控制控制单元(medium access control control element，MAC CE)或下行控制信息(downlink control information，DCI)向终端发送波束指示信息，从而终端和/网络侧设备可以确定该波束指示信息指示的波束的波束应用时间(beam application time，BAT)。
通常，终端可以从发送上述波束指示信息的响应消息(Acknowledgement，ACK)所在的载波单元(component carrier，CC)(以下简称为CC0)、该波束指示信息对应的CC中选择具有最小子载波间隔(Subcarrier spacing，SCS)的CC作为参考CC，然后将该参考CC对应的时域资源上，从计时起点开始的Y个符号后的第一个slot作为该波束指示信息对应的所有CC的BAT。
然而，由于在载波聚合(carrier aggregation，CA)场景中，波束指示信息对应的CC可能属于不同的时间提前量组(timing advance group，TAG)，因此这些CC之间时隙(slot)和符号(symbol)可能无法对齐。如此，通过上述方式确定的BAT，可能会导致这些CC中的全部或部分CC的BAT位于slot的中间，而非slot的第一个符号，从而导致波束指示信息对应的CC的应用时间无法对齐，进而无法进行正确的数据传输。
发明内容
本申请实施例提供一种波束应用时间确定方法、装置及通信设备，能够解决CA场景中CC的应用时间无法对齐，而无法进行正确的数据传输的问题。

通过上述方案，由于属于一个TAG的CC在时域上具有一定的关联关系(比如SCS相同或SCS成倍数关系)，因此在目标CC组中的CC属于不同TAG或目标CC 组中的CC所属的TAG与ACK所在CC所属的TAG不同的情况下，通过确定参考CC对应的计时起点符号，并且确定目标CC对应的第一slot，以及根据第一slot，确定目标CC组中属于每个TAG的CC的BAT，可以使得目标CC组中属于同一个TAG的CC的波束生效时间一致，即可以使得属于同一个TAG的CC的波束对齐，从而可以正确地进行数据传输。

通过上述方案，由于属于一个TAG的CC的BWP在时域上具有一定的关联关系(比如SCS相同或SCS成倍数关系)，因此在目标BWP组中的BWP所属CC属于不同TAG或目标BWP组中的BWP所属CC所属的TAG与ACK所在BWP所属CC所属的TAG不同的情况下，通过确定参考BWP对应的计时起点符号，并且确定目标BWP对应的第一slot，以及根据第一slot，确定目标BWP组中属于每个TAG的CC的BWP的BAT，可以使得目标BWP组中所属CC属于同一个TAG的BWP的波束生效时间一致，即可以使得所属CC属于同一个TAG的BWP的波束对齐，从而可以正确地进行数据传输。

第五方面，提供了一种通信设备(包括终端和/网络侧设备)，该终端包括处理器、存储器及存储在存储器上并可在处理器上运行的程序或指令，程序或指令被处理器执行时实现如第一方面的方法的步骤。
第六方面，提供了一种通信设备，包括处理器及通信接口，其中，处理器用于根据第一符号，确定参考CC对应的计时起点符号，第一符号为波束指示信息的ACK占用的最后一个符号；并根据计时起点符号，确定目标CC对应的第一slot，目标CC为ACK所在CC或目标CC组中属于第一TAG的第一CC；以及根据第一slot，确定目标CC组中属于每个TAG的CC的BAT。或者。处理器用于根据第七符号，确定参考BWP对应的计时起点符号，第七符号为波束指示信息的ACK占用的最后一个符号；并根据计时起点符号，确定目标BWP对应的第四slot，目标BWP为ACK所在BWP或目标BWP组中所属CC属于第三TAG的第一BWP；以及根据第四slot，确定目标BWP组中属于每个TAG的CC的BWP的波束应用时间BAT。

可以理解，上述ACK所在CC为承载波束指示信息的ACK的CC。上述确定目标CC对应的第一slot可以为在目标CC的时域资源上确定第一slot。
步骤203、通信设备根据第一slot，确定目标CC组中属于每个TAG的CC的BAT。
本申请实施例中，在终端接收到波束指示信息之后，终端可以向网络侧设备发送波束指示信息的ACK。然后，通信设备(终端和/或网络侧设备)可以根据上述第一符号(波束指示信息的ACK占用的最后一个符号)，在参考CC的时域资源上确定上述计时起点符号，并根据该计时起点符号，在上述目标CC对应的时域资源上确定第一slot，然后再根据该第一slot，确定目标CC组中属于每个TAG的CC的BAT，即通信设备可以根据该第一slot，确定目标CC组中的每个TAG的CC的BAT。
需要说明的是，本申请实施例中，上述目标CC组中的CC可以为应用上述波束指示信息的CC。其中，该波束指示信息可以为公共波束(common beam)指示信息。
可选地，本申请实施例中，上述目标CC组中的CC和ACK所在CC属于至少两个TAG。
可选地，本申请实施例中，目标CC组中的CC可以属于至少一个TAG。其中，在目标CC组中的CC属于一个TAG的情况下，ACK所在CC所属的TAG与目标CC组中的CC所属的TAG不同；在目标CC组中的CC属于多个TAG的情况下，ACK所在CC所属的TAG与目标CC组中的CC所属的TAG可以相同，也可以不同，具体可以根据实际使用需求确定，本申请对此不作限定。
需要说明的是，当本申请提及“多个CC属于一个TAG”时，也可以理解为该多个CC所对应的小区属于同一个TAG。
可选地，本申请实施例中，在目标CC组中的CC属于至少两个TAG的情况下，该至少两个TAG对应同一个传输配置指示(transmission configuration indicator，TCI)状态池(state pool)，或者该至少两个TAG对应不同的TCI状态池。即，网络侧设备为目标CC组配置TCI state pool时，无论目标CC组中的CC属于几个TAG，可以为目标CC组中的CC配置一个TCI state pool，也可以根据目标CC组中的CC所属的TAG，为属于同一TAG的CC配置一个TCI state pool，为属于另一个TAG的CC配置另一个TCI state pool。
本申请实施例中，网络侧设备可以通过下行信息，例如下行控制信息(DCI)，指示目标CC组中的CC对应的TCI state，然后根据该TCI state，确定目标CC组中的CC的下行公共波束信息和/或上行公共波束信息。
可选地，本申请实施例中，上述参考CC(用于确定计时起点符号的CC)可以为上述ACK所在CC、上述第一CC或目标CC组中属于第二TAG的第二CC。
可以理解，在上述参考CC为上述第二CC的情况下，上述目标CC组中的CC可以属于多个TAG。
本申请实施例中，上述参考CC不同时，确定的计时起点符号不同，且目标CC也不同，从而确定的第一slot也不同。如此，目标CC组属于每个TAG的CC的BAT也不同。下面以参考CC的三种情况，对本申请实施例提供的波束应用时间确定方法进行示例性地说明。
第一种情况：参考CC为第一CC，该第一CC为第一TAG中SCS最小的CC。
基于上述第一种情况，在一种实现方式中，上述计时起点符号可以为根据第一符号确定的符号。可以理解，上述计时起点符号可以为第一符号在上述第一CC对应的时域资源上的映射位置对应的符号。
在另一种实现方式中，计时起点符号可以为根据第一符号和第一时间提前量(timing advance，TA)确定的符号。其中，上述第一TA可以包括以下至少一项：第 一TAG对应的TA、ACK所在CC所属的TAG对应的TA。
可以理解，上述计时起点符号可以为第一符号在上述第一CC对应的时域资源上的映射位置减去和/或加上第一TA后对应的符号。或者说，上述计时起点符号可以为第一符号在上述第一CC对应的时域资源上的映射位置向后回退和/或向前前进第一TA后对应的符号。其中，向后回退是指向位于第一符号在上述第一CC对应的时域资源上的映射位置之前(before)的符号数，向前前进是指向位于第一符号在上述第一CC对应的时域资源上的映射位置之后(after/next)的符号数。如，所述映射位置在符号n，从符号n向后回退m个符号，则为符号(n-m)，从符号n向前前进k个符号，则为符号(n+k)。
还可以理解为，若第一符号的时间为t1，ACK所在CC所属的TAG对应的TA和第一TAG对应的TA之间相差的时间为t2，若ACK所在CC所属的TAG对应的TA大于第一TAG对应的TA，则计时起点符号的时间为(t1+t2)，若ACK所在CC所属的TAG对应的TA小于第一TAG对应的TA，则计时起点符号的时间为(t1-t2)。
示例性地，假设上述第一TAG对应的TA为3个符号，ACK所在CC所属的TAG对应的TA为5个符号，那么上述计时起点符号可以为第一符号在第一CC对应的时域资源上的映射位置加上5个符号，再减去3个符号之后对应的符号。也就是说，根据第一TAG对应的TA和ACK所在CC所属的TAG对应的TA确定的计时起点符号，相比于ACK所在CC对应的时域资源上的符号在时间上落后2个符号，需要将第一符号在第一CC对应的时域资源上的映射位置向前前进2个符号，若映射位置为第一CC对应的时域资源上的符号n，则计时起点符号为符号(n+2)。
另外，上述ACK所在CC所属的TAG与第一TAG可以为不同的TAG。
可选地，在上述第一种情况中，在目标CC为上述第一CC的情况下，第一slot可以为第一CC对应的时域资源上，位于计时起点符号之后的Y个符号后的第一个slot。
需要说明的是，上述Y的值可以为网络侧设备配置的。其中，网络配置的每个Y可以对应一组CC、BWP、SCS中的至少一项。
可选地，基于上述第一种情况，目标CC组中，属于第一TAG的CC的BAT为第一slot。
可以理解，对于上述第一种情况，通信设备可以通过确定第一TAG中SCS最小的CC的BAT，确定第一TAG中所有CC的BAT。
下面结合附图对上述第一种情况(参考CC和目标CC均为第一CC)进行示例性地说明。
一种可能的情况：目标CC组中的CC属于同一个TAG。
假设ACK所在CC(以下称为CC0)属于TAG1，目标CC组中的CC均属于TAG2。若属于TAG2的CC中，CC1(即上述第一CC)的SCS最小，则将属于TAG2中CC1作为参考(reference)CC。
示例1：如图3所示，根据CC0所属的TAG1对应的TA和TAG2对应的TA中的至少一个，将T0(ACK在CC0上占用的最后一个符号，即第一符号)映射到CC1对应的时域资源上的第一时间点T1(即计时起点符号)，然后根据CC1的SCS，从T1开始的数Y个符号，将位于第Y个符号后的first slot(第一个slot)作为第一slot，从而将该first slot作为属于TAG2的CC的BAT。
示例2：如图4所示，将T0(ACK在CC0上占用的最后一个符号，即第一符号)映射到CC1对应的时域资源上的第二时间点T2(即计时起点符号)，然后根据CC1的SCS，从T2开始数Y个符号，将位于第Y个符号后的first slot作为第一slot，从而将该first slot作为属于TAG2的CC的BAT。
另一种可能的情况：目标CC组中的CC属于不同的TAG。
假设ACK所在CC(以下称为CC0)属于TAG1，目标CC组中的CC，一部分属于TAG2，另一部分属于TAG3。若属于TAG2的CC中，CC1的SCS最小，则将CC1作为TAG2对应的参考(reference)CC；属于TAG3的CC中，CC2的SCS最小，则将CC2作为TAG3对应的参考CC。
示例3：如图5所示，根据CC0所属的TAG1对应的TA和TAG2对应的TA中的至少一个，将T0(ACK在CC0上占用的最后一个符号，即第一符号)映射到CC1对应的时域资源上的第一时间点TAG2-T1(即TAG2对应的计时起点符号)，然后根据CC1的SCS，从TAG2-T1开始数Y个符号，将位于第Y个符号(TAG2-T6)后的first slot作为TAG2对应的第一slot，从而将该first slot作为属于TAG2的CC的BAT。并且，根据CC0所在的TAG1对应的TA和TAG3对应的TA中的至少一个，将T0映射到CC2对应的时域资源上的第一时间点TAG3-T1(即TAG3对应的计时起点符号)，然后根据CC2的SCS，从TAG3-T1开始数Y个符号，将位于第Y个符号(TAG3-T6)后的first slot作为TAG3对应的第一slot，从而将该first slot作为属于TAG3的CC的BAT。
示例4：如图6所示，将T0(即第一符号)映射到CC1对应的时域资源上的第二时间点TAG2-T2(即TAG2对应的计时起点符号)，然后根据CC1的SCS，从TAG2-T2开始数Y个符号，将位于第Y个符号(TAG2-T6)后的first slot作为TAG2对应的第一slot，从而将该first slot作为属于TAG2的CC的BAT。并且，将T0(即第一符号)映射到CC2对应的时域资源上的第二时间点TAG3-T2(即TAG3对应的计时起点符号)，然后根据CC2的SCS，从TAG3-T2开始数Y个符号，将位于第Y个符号(TAG3-T6)后的first slot作为TAG3对应的第一slot，从而将该first slot作为属于TAG3的CC的BAT。
需要说明的是，对于每个TAG对应的Y的值可以相同，也可以不同，具体可以根据实际使用需求确定，本申请实施例不作限定。
另外，在目标CC组中的CC属于多个TAG的情况下，TAG的数量不作限定，例如2个TAG、3个TAG或4个TAG等，本申请是以2个TAG为例，进行示例性说明的。对于目标CC组中的CC属于其它数量的TAG的实现方式，与目标CC组中的CC属于2个TAG的实现方式类似，为避免重复，本文将不予赘述。
第二种情况：参考CC为第二CC，该第二CC为上述目标CC组中SCS最小的CC。
基于上述第二种情况，在一种实现方式中，上述计时起点符号可以为根据第一符号确定的符号。可以理解，上述计时起点符号可以为第一符号在上述第二CC对应的时域资源上的映射位置对应的符号。
在另一种实现方式中，计时起点符号为根据第一符号和第二TA确定的符号。其中，上述第二TA可以包括以下至少一项：第二TAG对应的TA、ACK所在CC所属的TAG对应的TA。
可以理解，上述计时起点符号可以为第一符号在上述第二CC对应的时域资源上的映射位置减去和/或加上第二TA后对应的符号。或者说，上述计时起点符号可以为第一符号在上述第二CC对应的时域资源上的映射位置向后回退和/或向前前进第二TA后对应的符号。其中，向后回退是指向位于第一符号在上述第二CC对应的时域资源上的映射位置之前(before)的符号数，向前前进是指向位于第一符号在上述第二CC对应的时域资源上的映射位置之后(after/next)的符号数。如，所述映射位置在符号n，从符号n向后回退m个符号，则为符号(n-m)，从符号n向前前进k个符号， 则为符号(n+k)。
还可以理解为，若第一符号的时间为t1，ACK所在CC对应的TA和第二TAG对应的TA之间相差的时间为t2，若ACK所在CC对应的TA大于第二TAG对应的TA，则计时起点符号的时间为(t1+t2)，若ACK所在CC对应的TA小于第二TAG对应的TA，则计时起点符号的时间为(t1-t2)。
示例性地，假设上述第二TAG对应的TA为2个符号，ACK所在CC所属的TAG对应的TA为5个符号，那么上述计时起点符号可以为第一符号在第二CC对应的时域资源上的映射位置加上5个符号，再减去2个符号之后对应的符号。也就是说，根据第二TAG对应的TA和ACK所在CC所属的TAG对应的TA确定的计时起点符号，相比于ACK所在CC对应的时域资源上的符号在时间上落后3个符号，需要将第一符号在第一CC对应的时域资源上的映射位置向前前进数3个符号，若映射位置为第一CC对应的时域资源上的符号n，则计时起点符号为符号(n+3)。
需要说明的是，基于上述第二种情况，上述ACK所在CC所属的TAG与第一TAG和第二TAG可以为不同的TAG，也可以为相同的TAG，具体可以根据实际使用需求确定，本申请实施例不作限定。
另外，第一TAG和第二TAG可以为不同的TAG。
可选地，在上述第二种情况中，在目标CC可以为上述第一CC，第一CC可以为第一TAG中SCS最小的CC的情况下，第一slot可以为第一CC对应的时域资源上，位于第二符号之后的第一个slot。
可选地，在一些实施例中，上述第二符号可以为根据第二slot确定的符号。
其中，上述第二slot可以为第二CC对应的时域资源上，位于第三符号之后的第一个slot，该第三符号可以为第二CC对应的时域资源上，位于计时起点符号之后的第Y个符号。可以理解，上述第二符号可以为第二slot(或理解为第二slot中的第一个符号)在第一CC对应的时域资源上的映射位置对应的符号。
在一些实施例中，上述第二符号可以为根据第二slot和第三TA确定的符号。其中，上述第三TA可以包括以下至少一项：第一TAG对应的TA、第二TAG对应的TA。
可以理解，上述第二符号可以为第二slot(例如第二slot的第一个符号)在上述第一CC对应的时域资源上的映射位置减去和/或加上第三TA后对应的符号。或者说，上述第二符号可以为第二slot(例如第二slot的第一个符号)在上述第一CC对应的时域资源上的映射位置向后回退和/或向前前进第三TA后对应的符号。其中，向后回退是指向位于第二slot(例如第二slot的第一个符号)在上述第一CC对应的时域资源上的映射位置之前(before)的符号数，向前前进是指向位于第二slot(例如第二slot的第一个符号)在上述第一CC对应的时域资源上的映射位置之后(after/next)的符号数。如，所述映射位置在符号n，从符号n向后回退m个符号，则为符号(n-m)，从符号n向前前进k个符号，则为符号(n+k)。
还可以理解为，若第二slot的第一个符号的时间为t3，第一TAG对应的TA和第二TAG对应的TA之间相差的时间为t4，若第二TAG对应的TA大于第一TAG对应的TA，则计时起点符号的时间为(t3+t4)，若第二TAG对应的TA小于第一TAG对应的TA，则计时起点符号的时间为(t3-t4)。
示例性地，假设上述第一TAG对应的TA为3个符号，第二TAG对应的TA为2个符号，那么上述第二符号可以为第二slot在第一CC对应的时域资源上的映射位置加上2个符号，再减去3个符号之后对应的符号。也就是说，根据第一TAG对应的TA和第二TAG对应的TA确定的第二符号，相比于第二CC对应的时域资源上的符 号在时间上提前一个符号，需要将第二slot在第一TAG对应的时域资源上的映射位置向后回退1个符号，若映射位置为第一CC对应的时域资源上的符号n，则第二符号为符号(n-1)。
在另一些实施例中，上述第二符号可以为根据第三符号确定的符号。
其中，第三符号可以为第二CC对应的时域资源上，位于计时起点符号之后的第Y个符号。可以理解，上述第二符号可以为第三符号在第一CC对应的时域资源上的映射位置对应的符号。
在又一些实施例中，第二符号为根据第三符号和第三TA确定的符号。其中，第三TA可以包括以下至少一项：第一TAG对应的TA、第二TAG对应的TA。
可以理解，上述第二符号可以为第三符号在上述第一CC对应的时域资源上的映射位置减去和/或加上第三TA后对应的符号。或者说，上述第二符号可以为第三符号在上述第一CC对应的时域资源上的映射位置向后回退和/或向前前进第三TA后对应的符号。其中，向后回退是指向位于第三符号在上述第一CC对应的时域资源上的映射位置之前(before)的符号数，向前前进是指向位于第三符号在上述第一CC对应的时域资源上的映射位置之后(after/next)的符号数。如，所述映射位置在符号n，从符号n向后回退m个符号，则为符号(n-m)，从符号n向前前进k个符号，则为符号(n+k)。
还可以理解为，若第三符号的时间为t3，第一TAG对应的TA和第二TAG对应的TA之间相差的时间为t4，若第二TAG对应的TA大于第一TAG对应的TA，则计时起点符号的时间为(t3+t4)，若第二TAG对应的TA小于第一TAG对应的TA，则计时起点符号的时间为(t3-t4)。
本申请实施例中，基于上述第二种情况，属于第一TAG的CC的BAT可以为第一slot，属于第二TAG的CC的BAT可以为第二slot。
可以理解，对于上述第二种情况，通信设备可以通过确定第一CC(第一TAG中SCS最小的CC)的BAT，确定第一TAG中所有CC的BAT；并且通过确定第二CC(目标CC组中SCS最小的CC)的BAT，确定第二TAG中所有CC的BAT。
下面结合附图对上述第二种情况(参考CC为第二CC、目标CC为第一CC)进行示例性地说明。
假设ACK所在CC(以下称为CC0)属于TAGX，目标CC组中的CC，一部分属于TAG2，另一部分属于TAG3。若目标CC组中，属于TAG2的CC1的SCS最小，则将CC1作为TAG2和TAG3共同的参考(reference)CC。其中，TAGX可以与TAG2或TAG3相同，也可以与TAG2和TAG3均不同。
示例5：如图7所示，根据CC0所属的TAGX的TA和TAG2对应的TA中的至少一个，将T0(ACK在CC0上占用的最后一个符号，即第一符号)映射到CC1对应的时域资源上的第一时间点T1(即计时起点符号)；然后根据CC1的SCS，从T1开始数Y个符号，将位于第Y个符号(T6，即上述第三符号)后的first slot(第一个slot)作为TAG2对应的第一slot，从而将该first slot作为属于TAG2的CC的BAT。并且根据TAG2的TA和TAG3的TA中的至少一个，将T6(即上述第三符号)映射到TAG3中具有最小SCS的CC2(即上述第一CC)对应的时域资源上的T7(即上述第二符号)，并将CC2对应的时域资源上，位于T7之后的下一个slot作为CC2的first slot，从而将位于T7之后的下一个slot作为属于TAG3的CC的BAT。
示例6：如图8所示，将T0(ACK在CC0上占用的最后一个符号，即第一符号)映射到CC1对应的时域资源上的第一时间点T1(即计时起点符号)；然后根据CC1的SCS，从T1开始数Y个符号，将位于第Y个符号(T6，即上述第三符号)后的first  slot(第一个slot)作为TAG2对应的第一slot，从而将该first slot作为属于TAG2的CC的BAT。并且根据TAG2的TA和TAG3的TA中的至少一个，将T6(即上述第三符号)映射到TAG3中具有最小SCS的CC2(即上述第一CC)对应的时域资源上的T7(即上述第二符号)，并将CC2对应的时域资源上，位于T7之后的下一个slot作为CC2的first slot，从而将CC2的first slot作为属于TAG3的CC的BAT。
示例7：如图9所示，根据CC0所在TAGX的TA和TAG2对应的TA中的至少一个，将T0(ACK在CC0上占用的最后一个符号，即第一符号)映射到CC1对应的时域资源上的第一时间点T1(即计时起点符号)；然后根据CC1的SCS，从T1开始数Y个符号，将位于第Y个符号(T6，即上述第三符号)后的first slot(第一个slot)作为TAG2对应的第一slot，从而将该first slot作为属于TAG2的CC的BAT。并且将T6(即上述第三符号)映射到TAG3中具有最小SCS的CC2(即上述第一CC)对应的时域资源上的T7(即上述第二符号)，并将CC2对应的时域资源上，位于T7之后的下一个slot作为CC2的first slot，从而将该first slot作为属于TAG3的CC的BAT。
示例8：如10所示，将T0(ACK在CC0上占用的最后一个符号，即第一符号)映射到CC1对应的时域资源上的第一时间点T2(即计时起点符号)；然后根据CC1的SCS，从T2开始数Y个符号，将位于第Y个符号(T6，即上述第三符号)后的first slot(第一个slot)作为TAG2对应的第一slot，从而将该first slot作为TAG2中的每个CC的BAT。并且将T6(即上述第三符号)映射到TAG3中具有最小SCS的CC2(即上述第一CC)对应的时域资源上的T7(即上述第二符号)，并将CC2对应的时域资源上，位于T7之后的下一个slot作为CC2的first slot，从而将该first slot作为属于TAG3的CC的BWP的BAT。
示例9：如图11所示，根据CC0所在TAGX的TA和TAG2对应的TA中的至少一个，将T0(ACK在CC0上占用的最后一个符号，即第一符号)映射到CC1对应的时域资源上的第一时间点T1(即计时起点符号)；然后根据CC1的SCS，从T1开始数Y个符号，将位于第Y个符号(T6，即上述第三符号)之后的first slot(即上述第二slot)作为TAG2对应的第一slot，从而将该first slot作为TAG2中的每个CC的BAT。并且根据TAG2的TA和TAG3的TA中的至少一个(或者不考虑TA)，将位于T6之后的first slot(即上述第二slot)映射到TAG3中具有最小SCS的CC2(即上述第一CC)对应的时域资源上的时间点，也就是将位于T6之后的first slot中的第一个符号映射到TAG3中具有最小SCS的CC2对应的时域资源上的符号位置，并将CC2对应的时域资源上，位于该时间点之后的下一个slot作为属于TAG3的CC的BAT。
示例10：如图12所示，将T0(ACK在CC0上占用的最后一个符号，即第一符号)映射到CC1对应的时域资源上的第一时间点T2(即计时起点符号)；然后根据CC1的SCS，从T2开始数Y个符号，将位于第Y个符号(T6，即上述第三符号)之后的first slot(即上述第二slot)作为TAG2对应的第一slot，从而将该first slot作为TAG2中的每个CC的BAT。并且根据TAG2的TA和TAG3的TA中的至少一个(或者不考虑TA)，将位于T6之后的first slot(即上述第二slot)映射到TAG3中具有最小SCS的CC2(即上述第一CC)对应的时域资源上的一个时间点，也就是将位于T6之后的first slot中的第一个符号映射到TAG3中具有最小SCS的CC2对应的时域资源上的符号位置，并将CC2对应的时域资源上，位于该时间点之后的下一个slot作为属于TAG3的CC的BAT。
第三种情况：参考CC为ACK所在CC，ACK所在CC为目标CC组中的CC和ACK所在CC中SCS最小的CC。
可选地，在上述第三种情况中，计时起点符号可以为第一符号。
基于上述第三种情况，在一种可能的实现方式中，目标CC可以为ACK所在CC。在该情况下，上述第一slot可以为ACK所在CC对应的时域资源上，位于计时起点符号之后的Y个符号后的第一个slot。
本申请实施例中，在目标CC为ACK所在CC的情况下，目标CC组中，属于同一个TAG组的CC的BAT为第三slot。
其中，上述第三slot可以为第三CC对应的时域资源上，位于第四符号之后的第一个slot，第三CC可以为同一个TAG组中SCS最小的CC。
在一种实现方式中，上述第四符号可以为根据第一slot确定的符号。
可以理解，上述第四符号可以为第一slot在第三CC对应的时域资源上的映射位置对应的符号。也就是说，上述第四符号可以为第一slot的第一个符号在第三CC对应的时域资源上的映射位置对应的符号。
在另一种实现方式中，第四符号为根据第一slot和第四TA确定的符号。其中，上述第四TA可以包括以下至少一项：第三CC所属的TAG对应的TA、ACK所在CC所属的TAG对应的TA。
可以理解，上述第四符号可以为第一slot在第三CC对应的时域资源上的映射位置对应的符号减去和/或加上第四TA后对应的符号。或者说，上述第四符号可以为第一slot(比如第一slot的第一个符号)在上述第三CC对应的时域资源上的映射位置向后回退和/或向前前进第四TA后对应的符号。其中，向后回退是指向位于第一slot(比如第一slot的第一个符号)在第三CC对应的时域资源上的映射位置之前(before)的符号数，向前前进是指向位于第一slot(比如第一slot的第一个符号)在第三CC对应的时域资源上的映射位置之后(after/next)的符号数。如，所述映射位置在符号n，从符号n向后回退m个符号，则为符号(n-m)，从符号n向前前进k个符号，则为符号(n+k)。
还可以理解为，若第一slot(例如第一slot的第一个符号)的时间为t5，ACK所在CC所属的TAG对应的TA和第三CC所属的TAG对应的TA之间相差的时间为t6，若ACK所在CC所属的TAG对应的TA大于第三CC所属的TAG对应的TA，则第四符号的时间为(T1+T2)，若ACK所在CC所属的TAG对应的TA小于第三CC所属的TAG对应的TA，则第四符号的时间为(T1-T2)。
示例性地，假设上述第三CC所属的TAG对应的TA为3个符号，ACK所在CC所属的TAG对应的TA为4个符号，那么上述第四符号可以为第一slot在第三CC对应的时域资源上的映射位置加上4个符号，再减去3个符号之后对应的符号。也就是说，根据第三CC所属的TAG对应的TA和ACK所在CC所属的TAG对应的TA确定的第四符号，相比于ACK所在CC对应的时域资源上的符号在时间上落后1个符号，需要将第一slot(例如第一slot的第一个符号)在第三CC对应的时域资源上的映射位置向前前进1个符号，若映射位置为第一CC对应的时域资源上的符号n，则计时起点符号为符号(n+1)。
下面再结合附图，对上述第三种情况的一种实现方式(参考CC和目标CC均为ACK所在CC)进行示例性地说明。
一种可能的情况：目标CC组中的CC属于同一个TAG。
假设ACK所在CC(以下称为CC0)属于TAG1，目标CC组中的CC均属于TAG2。若属于TAG2的CC中，CC1(即上述第三CC)的SCS最小，则将属于TAG2中CC1作为TAG2用于确定BAT的CC。
示例11：如图13所示，将T0(ACK在CC0上占用的最后一个符号，即第一符号)确定为即计时起点符号，根据CC0的SCS，从T0开始的数Y个符号，将位于第 Y个符号(记为T3)后的first slot(第一个slot)作为第一slot，从而根据CC0所在的TAG1对应的TA和TAG2对应的TA中的至少一个(或者不考虑TA)，将该first slot映射到CC1(即上述第三CC)对应的时域资源上的一个时间点，并将CC1对应的时域资源上，位于该时间点之后的下一个slot作为属于TAG2的CC的BAT。
另一种可能的情况：目标CC组中的CC属于不同的TAG。
假设ACK所在CC(以下称为CC0)属于TAG1，目标CC组中的CC，一部分属于TAG2，另一部分属于TAG3。若属于TAG2的CC中，CC1的SCS最小，则将CC1作为TAG2对应的第三CC；属于TAG3的CC中，CC2的SCS最小，则将CC2作为TAG3对应的第三CC。
示例12：如图14所示，将T0(ACK在CC0上占用的最后一个符号，即第一符号)确定为即计时起点符号，根据CC0的SCS，从T0开始的数Y个符号，将位于第Y个符号(记为T3)后的first slot(第一个slot)作为第一slot。然后根据CC0所在的TAG1对应的TA和TAG2对应的TA中的至少一个(或不考虑TA)，将该first slot映射到CC1(即TAG2对应的第三CC)对应的时域资源上的一个时间点，并将CC1对应的时域资源上，位于该时间点之后的下一个slot作为属于TAG2中的CC的BAT。并且根据CC0所在的TAG1对应的TA和TAG3对应的TA中的至少一个(或不考虑TA)，将该first slot映射到CC2(即TAG3对应的第三CC)对应的时域资源上的一个时间点，并将CC2对应的时域资源上，位于该时间点之后的下一个slot作为属于TAG3的CC的BAT。
基于上述第三种情况，在另一种可能的实现方式中，目标CC为第一CC，该第一CC为第一TAG中SCS最小的CC。在该种情况下，第一slot可以为第一CC对应的时域资源上，位于第五符号之后的第一个slot。
在一种实现方式中，上述第五符号可以为根据第六符号确定的符号。
其中，上述第六符号可以为ACK所在CC对应的时域资源上，位于计时起点符号之后的第Y个符号。可以理解，在上述实现方式中，第五符号可以为第六符号在第一CC对应的时域资源上的映射位置对应的符号。
在另一种实现方式中，上述第五符号可以为根据第六符号和第一TA确定的符号。其中，上述第一TA可以包括以下至少一项：第一TAG对应的TA、ACK所在CC所属的TAG对应的TA。
可以理解，在上述实现方式中，第五符号可以为第六符号在第一CC对应的时域资源上的映射位置对应的符号减去和/或加上第一TA后对应的符号。或者说，上述第五符号可以为第六符号在上述第一CC对应的时域资源上的映射位置向后回退和/或向前前进第一TA后对应的符号。其中，向后回退是指向位于第六符号在上述第一CC对应的时域资源上的映射位置之前(before)的符号数，向前前进是指向位于第六符号在上述第一CC对应的时域资源上的映射位置之后(after/next)的符号数。如，所述映射位置在符号n，从符号n向后回退m个符号，则为符号(n-m)，从符号n向前前进k个符号，则为符号(n+k)。
还可以理解为，若第六符号的时间为t7，ACK所在CC所属的TAG对应的TA和第一TAG对应的TA之间相差的时间为t8，若ACK所在CC所属的TAG对应的TA大于第一TAG对应的TA，则第五符号的时间为(t7+t8)，若ACK所在CC所属的TAG对应的TA小于第一TAG对应的TA，则第五符号的时间为(t7-t8)。
示例性地，假设上述第一TAG对应的TA为5个符号，ACK所在CC所属的TAG对应的TA为3个符号，那么上述第五符号可以为第六符号在第三CC对应的时域资源上的映射位置加上3个符号，再减去5个符号之后对应的符号。也就是说，根据第 一TAG对应的TA和ACK所在CC所属的TAG对应的TA确定的第五符号，相比于ACK所在CC对应的时域资源上的符号在时间上提前2个符号，需要将第六符号在第一CC对应的时域资源上的映射位置向后回退2个符号，若映射位置为第一CC上的符号n，则计时起点符号为符号(n-2)。
基于上述第三种情况，在目标CC为第一CC的情况下，目标CC组中，属于第一TAG的CC的BAT为第一slot。
下面再结合附图，对上述第三种情况的另一种实现方式(参考CC为ACK所在CC，目标CC为第一CC)进行示例性地说明。
一种可能的情况：目标CC组中的CC属于同一个TAG。
假设ACK所在CC(以下称为CC0)属于TAG1，目标CC组中的CC均属于TAG2。若属于TAG2的CC中，CC1(即上述第一CC)的SCS最小，则将属于TAG2中CC1作为TAG2用于确定BAT的CC。
示例13：如图15所示，将T0(ACK在CC0上占用的最后一个符号，即第一符号)确定为计时起点符号，根据CC0的SCS，从T0开始的数Y个符号，根据CC0所在的TAG1对应的TA和TAG2对应的TA中的至少一个，将第Y个符号(即上述第六符号，记为T3)映射到CC1对应的时域资源上的T4(即上述第五符号)，并将T4后的first slot作为第一slot，从而将该first slot作为属于TAG2的CC的BAT。
示例14：如图16所示，将T0(ACK在CC0上占用的最后一个符号，即第一符号)确定为计时起点符号，根据CC0的SCS，从T0开始的数Y个符号，将第Y个符号(即上述第六符号，记为T3)映射到CC1对应的时域资源上的T5(即上述第五符号)，并将T5后的first slot作为第一slot，从而将该first slot作为属于TAG2的CC的BAT。
另一种可能的情况：目标CC组中的CC属于不同的TAG。
假设ACK所在CC(以下称为CC0)属于TAG1，目标CC组中的CC，一部分属于TAG2，另一部分属于TAG3。若属于TAG2的CC中，CC1的SCS最小，则将CC1作为TAG2对应的目标CC；属于TAG3的CC中，CC2的SCS最小，则将CC2作为TAG3对应的目标CC。
示例15：如图17所示，将T0(ACK在CC0上占用的最后一个符号，即第一符号)确定为计时起点符号，根据CC0的SCS，从T0开始的数Y个符号。然后，根据CC0所在的TAG1对应的TA和TAG2对应的TA中的至少一个，将第Y个符号(即上述第六符号，记为T3)映射到CC1对应的时域资源上的TAG2-T4(即TAG2对应的第五符号)，并将TAG2-T4后的first slot作为第一slot，从而将该first slot作为属于TAG2的CC的BAT。并且根据CC0所在的TAG1对应的TA和TAG3对应的TA中的至少一个，将第Y个符号(即上述第六符号，记为T3)映射到CC2对应的时域资源上的TAG3-T4(即TAG3对应的第五符号)，并将TAG3-T4后的first slot(第一个slot)作为第一slot，从而将该first slot作为属于TAG3的CC的BAT。
示例16：如图18所示，将T0(ACK在CC0上占用的最后一个符号，即第一符号)确定为计时起点符号，根据CC0的SCS，从T0开始的数Y个符号。然后，将第Y个符号(即上述第六符号，记为T3)映射到CC1对应的时域资源上的TAG2-T5(即TAG2对应的第五符号)，并将TAG2-T5后的first slot(第一个slot)作为第一slot，从而将该first slot作为属于TAG2的CC的BAT。并且将第Y个符号(即上述第六符号，记为T3)映射到CC2对应的时域资源上的TAG3-T5(即TAG3对应的第五符号)，并将TAG3-T5后的first slot(第一个slot)作为第一slot，从而将该first slot作为属于TAG3的CC的BAT。
本申请实施例提供的波束应用时间确定方法，由于属于一个TAG的CC在时域上具有一定的关联关系(比如SCS相同或SCS成倍数关系)，因此在目标CC组中的CC属于不同TAG或目标CC组中的CC所属的TAG与ACK所在CC所属的TAG不同的情况下，通过确定参考CC对应的计时起点符号，并且确定目标CC对应的第一slot，以及根据第一slot，确定目标CC组中属于每个TAG的CC的BAT，可以使得目标CC组中属于同一个TAG的CC的波束生效时间一致，即可以使得属于同一个TAG的CC的波束对齐，从而可以正确地进行数据传输。
本申请实施例中，网络侧设备可以为一个CC所对应的小区配置多个BWP，该多个BWP包括激活BWP(active BWP)和非激活BWP(inactive BWP)，在传输数据的过程中，通信设备(例如终端和网络侧设备)可以在CC的一个BWP(active BWP)对应的时域资源上发送或接收数据，因此可以通过确定CC对应的时域资源上的一个BWP(例如SCS最小的BWP)的波束应用时间，确定CC(或CC的所有BWP)的波束应用时间。
如图19所示，本申请实施例提供一种波束应用时间确定方法，该波束应用时间确定方法可以包括下述的步骤301-步骤303。
步骤301、通信设备根据第七符号，确定参考BWP对应的计时起点符号。
其中，上述第七符号可以波束指示信息的ACK占用的最后一个符号。
步骤302、通信设备根据计时起点符号，确定目标BWP对应的第四slot。
其中，上述目标BWP可以为ACK所在BWP或目标BWP组中所属CC属于第三TAG的第一BWP。
可以理解，上述ACK所在BWP可以为承载波束指示信息的ACK的BWP，具体可以为承载波束指示信息的ACK的CC的BWP。
步骤303、通信设备根据第四slot，确定目标BWP组中属于每个TAG的CC的BWP的BAT。
本申请实施例中，在终端接收到波束指示信息之后，终端可以向网络侧设备发送波束指示信息的ACK。然后，通信设备(终端和/或网络侧设备)可以根据上述第七符号(波束指示信息的ACK占用的最后一个符号)，在参考BWP对应的时域资源上确定上述计时起点符号，并根据该计时起点符号在上述目标BWP对应的时域资源上确定第四slot，然后再根据该第四slot，确定目标BWP组中属于每个TAG的CC的BWP的BAT，即通信设备可以根据该第四slot，确定目标BWP组中的每个TAG的CC的BWP的BAT。
需要说明的是，本申请实施例中，上述目标BWP组中的BWP可以为应用上述波束指示信息的BWP。其中，该波束指示信息可以为公共波束(common beam)指示信息。
可选地，本申请实施例中，上述目标BWP组中的BWP所属CC和ACK所在BWP所属CC属于至少两个TAG。
可选地，本申请实施例中，目标BWP组中的BWP所属CC可以属于至少一个TAG。其中，在目标BWP组中的BWP所属CC属于一个TAG的情况下，ACK所在BWP所属CC所属的TAG与目标BWP组中的BWP所属CC所属的TAG不同；在目标BWP组中的BWP所属CC属于多个TAG的情况下，ACK所在BWP所属CC所属的TAG与目标BWP组中的BWP所属CC所属的TAG可以相同，也可以不同，具体可以根据实际使用需求确定，本申请对此不作限定。
可选地，本申请实施例中，在目标BWP组中的BWP所属CC属于至少两个TAG的情况下，该至少两个TAG对应同一个TCI状态池，或者该至少两个TAG对应不同 的TCI状态池。即，网络侧设备为目标BWP组中的BWP所属CC配置TCI state pool时，无论目标BWP组中的BWP所属CC属于几个TAG，可以为目标BWP组中的BWP所属CC配置一个TCI state pool，也可以根据目标BWP组中的BWP所属CC所属的TAG，为属于同一TAG的CC配置一个TCI state pool，为属于另一个TAG的CC配置另一个TCI state pool。
本申请实施例中，网络侧设备可以通过下行信息，例如下行控制信息(DCI)，指示目标BWP组中的BWP所属CC对应的TCI state，然后根据该TCI state，确定目标BWP组中的BWP的下行公共波束信息和/或上行公共波束信息。
可选地，本申请实施例中，上述参考BWP(用于确定计时起点符号的BWP)可以为上述ACK所在BWP、上述第一BWP或目标BWP组所属CC属于第四TAG的第二BWP。
可以理解，在上述参考BWP为上述第二BWP的情况下，上述目标BWP组中的BWP所属CC可以属于多个TAG。
本申请实施例中，上述参考BWP不同时，确定的计时起点符号不同，且目标BWP也不同，从而确定的第四slot也不同。如此，目标BWP组中属于每个TAG的CC的BWP的BAT也不同。下面以参考BWP的三种情况，对本申请实施例提供的波束应用时间确定方法进行示例性地说明。
情况一：参考BWP为第一BWP，该第一BWP为属于第三TAG的CC中SCS最小的BWP。
基于上述情况一，在一种实现方式中，上述计时起点符号可以为根据第七符号确定的符号。可以理解，上述计时起点符号可以为第七符号在上述第一BWP对应的时域资源上的映射位置对应的符号。
在另一种实现方式中，计时起点符号可以为根据第七符号和第五TA确定的符号。其中，上述第五TA可以包括以下至少一项：第三TAG对应的TA、ACK所在BWP所属CC所属的TAG对应的TA。
可以理解，上述计时起点符号可以为第七符号在上述第一BWP对应的时域资源上的映射位置减去和/或加上第五TA后对应的符号。或者说，上述计时起点符号可以为第七符号在上述第一BWP对应的时域资源上的映射位置向后回退和/或向前前进第五TA后对应的符号。其中，向后回退是指向位于第七符号在上述第一BWP对应的时域资源上的映射位置之前(before)的符号数，向前前进是指向位于第七符号在上述第一BWP对应的时域资源上的映射位置之后(after/next)的符号数。如，所述映射位置在符号n，从符号n向后回退m个符号，则为符号(n-m)，从符号n向前前进k个符号，则为符号(n+k)。
对于如何确定计时起点符号的举例，具体可以参见上述实施例中，在第一CC对应的时域资源上确定计时起点符号的相关举例，为避免重复，此处不再赘述。

另一种可能的情况：目标BWP组中的BWP所属CC属于不同的TAG。
假设ACK所在BWP(以下称为BWP0)所属CC属于TAG1，目标BWP组中的BWP所属CC，一部分属于TAG2，另一部分属于TAG3。若属于TAG2的CC中，BWP1的SCS最小，则将BWP1作为TAG2对应的目标BWP；属于TAG3的CC中，BWP2的SCS最小，则将BWP2作为TAG3对应的目标BWP。
示例31：如图17所示，将T0(ACK在BWP0上占用的最后一个符号，即第七符号)确定为计时起点符号，根据BWP0的SCS，从T0开始的数Y个符号。然后，根据BWP0所在的TAG1对应的TA和TAG2对应的TA中的至少一个，将第Y个符号(即上述第十二符号，记为T3)映射到BWP1对应的时域资源上的TAG2-T4(即TAG2对应的第十一符号)，并将位于TAG2-T4之后的first slot作为第四slot，从而将该first slot作为属于TAG2的CC的BWP的BAT。并且根据BWP0所在的TAG1对应的TA和TAG3对应的TA中的至少一个，将第Y个符号(即上述第十二符号，记为T3)映射到BWP2对应的时域资源上的TAG3-T4(即TAG3对应的第十一符号)，并将位于TAG3-T4之后的first slot作为第四slot，从而将该first slot作为属于TAG3的CC的BWP的BAT。
示例32：如图18所示，将T0(ACK在BWP0上占用的最后一个符号，即第七符号)确定为计时起点符号，根据BWP0的SCS，从T0开始的数Y个符号。然后，将第Y个符号(即上述第十二符号，记为T3)映射到BWP1对应的时域资源上的TAG2-T4(即TAG2对应的第十一符号)，并将位于TAG2-T5之后的first slot作为第四slot，从而将该first slot作为属于TAG2的CC的BWP的BAT。并且将第Y个符号(即上述第十二符号，记为T3)映射到BWP2对应的时域资源上的TAG3-T5(即TAG3对应的第十一符号)，并将位于TAG3-T5之后的first slot作为第四slot，从而将该first slot作为属于TAG3的CC的BWP的BAT。
