在本实施例中,目标功控参数可以用于目标单元上的PUCCH、PUSCH、SRS中的至少一种。
在本申请实施例提供的上述技术方案中,通信设备获取网络侧设备配置的至少一组成员载波,对于其中的第一目标成员载波组,获取网络侧设备为该第一目标成员载波组激活或指示的第一公共TCI状态信息,再根据该第一公共TCI状态信息,确定第一目标成员载波组中的各个CC和/或BWP的目标功控参数,从而可以在统一TCI框架下,获得不同CC的功控参数信息。保证CA场景中功率控制的准确性。
在第一种可能的实现方式中,在S214中,所述通信设备根据所述第一公共TCI状态信息,确定所述第一目标成员载波组中各个目标单元的目标功控参数,可以包括:
在所述第一公共TCI状态信息包括第一功控参数标识,或者,所述第一公共TCI状态信息关联第一功控参数标识的情况下,将所述第一目标成员载波组中的各个目标单元的目标功控参数均设置为所述第一功控参数标识对应的一个公共功控参数。
例如,在公共TCI state中包括PLRS ID,或者公共TCI state关联PLRS ID,或者公共TCI state ID中包括PLRS ID,或者公共TCI state ID关联PLRS ID时,将包括或关联的所述PLRS ID对应的一个公共PLRS用于组中所有CC。
再例如,在公共TCI state中包括PC setting ID,或者公共TCI state关联PC setting ID,或者在公共TCI state ID中包括PC setting ID,或者公共TCI state ID关联PC setting ID时,将包括或关联的所述PC setting ID对应的一个公共PC setting用于组中所有CC。
在上述可能的实现方式中,网络设备是通过显式配置的方式来确定功控参数信息,如,在公共TCI state信息中配置了PLRS ID和/或PC setting ID,或者将公共TCI state信息与PLRS ID和/或PC setting ID配置为相互关联。
特别的,UE能力可以支持波束错位(beam misalignment),也即公共TCI state指示的波束信息与PLRS的波束信息不一致,或者说公共TCI state中的 QCL-D型(TypeD)source RS与PLRS不同或者不是QCL的,此时网络设备可以显式配置与公共TCI state中的QCL-TypeD source RS不同的PLRS。
在上述可能的实现方式中,所述一个公共功控参数为所述第一目标成员载波组中的参考目标单元上的功控参数,或者所述一个公共功控参数为所述第一目标成员载波组中的预设目标单元上的功控参数。
例如,公共TCI state ID包括或关联的所述一个公共PLRS为该组CC中参考CC和/或参考BWP上的RS或某个预设CC/BWP上的RS。例如,该组CC包括CC0,CC1,CC2,CC3,参考CC为CC0,根据PLRS ID确定出CC0上的PLRS,并将该PLRS作为这4个CC上的PLRS。
在上述可能的实现方式中,可选地,将所述第一目标成员载波组中的各个目标单元的目标功控参数均设置为所述第一功控参数标识对应的一个公共功控参数,包括:
在根据所述第一公共TCI状态信息确定所述第一目标成员载波组中的各个目标单元上的QCL类型D的参考信号为一个共同的QCL类型D源参考信号的情况下,将所述第一目标成员载波组中的各个目标单元的目标功控参数均设置为所述第一功控参数标识对应的一个公共功控参数。
例如,根据公共TCI state ID确定的每个CC和/或BWP上的QCL-TypeD RS是一个共同QCL-TypeD source RS的情况下,将所述第一目标成员载波组中的各个目标单元的目标功控参数均设置为所述第一功控参数标识对应的一个公共功控参数。根据公共TCI state ID确定的每个CC和/或BWP上的QCL-TypeD RS是一个共同QCL-TypeD source RS,即公共TCI state ID中的一个source RS是跨CC的,即该source RS用于所有目标CC,此时,第一目标成员载波组中的各个目标单元的目标功控参数也采用类似的确定方式,即各个目标单元共享相同的目标功控参数。
在第二种可能的实现方式,在S214中所述通信设备根据所述第一公共TCI状态信息,确定所述第一目标成员载波组中各个目标单元的目标功控参 数,可以包括:
在所述第一公共TCI状态信息包括第一功控参数标识,或者,所述第一公共TCI状态信息关联第一功控参数标识的情况下,根据所述第一功控参数标识,分别确定所述第一目标成员载波组中的各个目标单元的目标功控参数。
例如,在公共TCI state中包括PLRS ID,或者公共TCI state关联PLRS ID,或者公共TCI state ID中包括PLRS ID,或者公共TCI state ID关联PLRS ID的情况下,在第一目标成员载波组中的每个CC上,根据所述PLRS ID确定每个CC/BWP上各自的PLRS。
再例如,在公共TCI state中包括PC setting ID,或者公共TCI state关联PC setting ID,或者在公共TCI state ID中包括PC setting ID,或者公共TCI state ID关联PC setting ID时,将包括或关联的所述PC setting ID对应的一个公共PC setting用于组中所有CC。
在上述可能的实现方式中,网络设备是通过显式配置的方式来确定功控参数信息,如,在公共TCI state信息中配置了PLRS ID和/或PC setting ID,或者将公共TCI state信息与PLRS ID和/或PC setting ID配置为相互关联。
特别的,UE能力可以支持beam misalignment,也即公共TCI state指示的波束信息与PLRS的波束信息不一致,或者说公共TCI state中的QCL-TypeD source RS与PLRS不同或者不是QCL的,此时网络设备可以显式配置与公共TCI state中的QCL-TypeD source RS不同的PLRS。
在上述可能的实现方式中,各个所述目标单元的目标功控参数不完全相同,且各个所述目标单元的目标功控参数是QCL的。例如,每个CC/BWP上各自的PLRS可以不同,但却是QCL的,其中一个CC/BWP上的PLRS为其它CC/BWP上PLRS的QCL source RS,或者这些CC/BWP上的PLRS有共同的一个QCL source RS。例如,该组CC包括CC0,CC1,CC2,CC3,CC0上的PLRS为对应PLRS ID的RS0,CC1上的PLRS为对应PLRS ID的RS1,CC2上的PLRS为对应PLRS ID的RS2,CC3上的PLRS为对应PLRS ID的 RS3。这4个RS是QCL的,比如,RS0是RS1、RS2、RS3的QCL source RS,或者这4个RS具有共同的QCL source RS(如SSB)。
在上述可能的实现方式中,可选地,各个所述目标单元的目标功控参数不完全相同,且各个所述目标单元的目标功控参数不全是QCL的。例如,每个CC/BWP上各自的PLRS可以不同,也不全都是QCL的。
在上述可能的实现方式中,根据所述第一功控参数标识,分别确定所述第一目标成员载波组中的各个目标单元的目标功控参数,包括:
在根据所述第一公共TCI状态信息分别确定所述第一目标成员载波组中的各个目标单元上的QCL类型D源参考信号的情况下,根据所述第一功控参数标识,分别确定所述第一目标成员载波组中的各个目标单元的目标功控参数。
例如,在根据公共TCI state ID确定的每个CC/BWP上的QCL-TypeD RS是相互不同的QCL-TypeD source RS,则对各CC/BWP上的功控参数也采用类似的确定方式,如根据包括或关联的功控参数标识分别确定各CC/BWP上的目标功控参数。
在具体应用中,上述第一种可能实现方式和第二种可能实现方式进行组合,例如,可以根据所述第一公共TCI状态信息所确定的所述第一目标成员载波组中的各个目标单元上的QCL类型D源参考信号是一个共同的QCL类型D源参考信号还是分别确定所述第一目标成员载波组中的各个目标单元上的QCL类型D源参考信号,来确定是采用上述第一种可能实现方式,还是第二种可能实现方式。
例如,根据公共TCI state ID确定的每个CC/BWP上的QCL-TypeD RS是一个共同QCL-TypeD source RS还是各自不同的QCL-TypeD source RS,来确定各CC/BWP上的功控参数是使用上述第一种可能实现方式或第二种可能实现方式。也就是说,每个CC/BWP的功控参数信息采用与波束信息相同的确定方式。
在又一个可能的实现方式中,在S214中,所述通信设备根据所述第一公共TCI状态信息,确定所述第一目标成员载波组中各个目标单元的目标功控参数,包括:
在所述第一公共TCI状态信息包括多个第一功控参数标识或者所述第一公共TCI状态信息关联多个第一功控参数标识,且所述多个第一功控参数标识的数量与所述第一目标成员载波组中的目标单元的数量相同的情况下,每个所述目标单元的目标功控参数根据与该目标单元对应的第一功控参数标识确定,其中,各个所述目标单元按照预设的排列顺序或位置分别与一个所述第一功控参数一一对应。
例如,在公共TCI state中包括PLRS ID,或者公共TCI state关联PLRS ID,或者公共TCI state ID中包括PLRS ID,或者公共TCI state ID关联PLRS ID,所述PLRS ID的数量与该组CC/BWP中的CC/BWP数量相同,则PLRS ID和CC/BWP是根据预设的排列或者位置相互对应的。
再例如,在公共TCI state中包括PC setting ID,或者公共TCI state关联PC setting ID,或者在公共TCI state ID中包括PC setting ID,或者公共TCI state ID关联PC setting ID时,所述PC setting ID的数量与该组CC/BWP中的CC/BWP数量相同,则PC setting ID和CC/BWP是根据预设的排列或者位置相互对应的。
在又一个可能的实现方式中,在S214中,所述通信设备根据所述第一公共TCI状态信息,确定所述第一目标成员载波组中各个目标单元的目标功控参数,可以包括:
在所述第一公共TCI状态信息不包括第一功控参数标识,且所述第一公共TCI状态信息也未关联第一功控参数标识的情况下,根据所述第一公共TCI信息确定所述第一目标成员载波组中各个目标单元的QCL类型D的参考信号,将各个所述目标单元的QCL类型D的参考信号作为所述目标单元的PLRS;和/或,
在所述第一公共TCI状态信息不包括第一功控参数标识,且所述第一公共TCI状态信息也未关联第一功控参数标识的情况下,由网络侧设备指示所述PLRS之外的功控参数集合或按照约定确定所述PLRS之外的功控参数集合。
在上述可能的实现方式中,网络设备是通过隐式配置的方式来确定功控参数信息,如,将公共TCI state信息的QCL-TypeD source RS作为PLRS,对PC setting中的各功控参数值取协议约定的默认值,或者,网络设备指示出在隐式配置情况下的PLRS和PC setting中的功控参数。
特别的,UE能力可以不支持beam misalignment,也即公共TCI state指示的波束信息与PLRS的波束信息必须一致,或者说公共TCI state中的QCL-TypeD source RS与PLRS相同或者是QCL的,此时网络设备不需要额外显式配置PLRS,而是可以直接将根据公共TCI state信息确定的QCL-TypeD source RS作为PLRS。
例如,在公共TCI state中不包括PLRS ID,或者公共TCI state不关联PLRS ID,或者common TCI state ID中不包括PLRS ID,也不关联PLRS ID,根据common TCI state ID确定的该组CC/BWP中的每个CC/BWP的QCL-TypeD RS,作为各CC/BWP的PLRS。
再例如,在公共TCI state中不包括PC setting ID,或者公共TCI state不关联PC setting ID,或者在公共TCI state ID中不包括PC setting ID,或者公共TCI state ID不关联PC setting ID时,则对该组CC/BWP中的每个CC/BWP中的PC setting中的各参数值取协议约定的默认值,或者由网络指示预设值。
在上述各个可能的实现方式中,所述第一公共TCI状态信息包括第一功控参数标识,包括:所述第一公共TCI状态信息包括第一公共TCI状态标识,所述第一公共TCI状态标识中包含所述第一功控参数标识,即第一公共TCI状态信息中的一个参数为第一公共TCI状态标识,该标识中包含有第一功控参数标识;或者,所述第一公共TCI状态信息包括所述第一功控参数标识, 即第一公共TCI状态中包括一个功控参数标识的参数,该参数的值为第一功控参数标识。

在一个可能的实现方式中,所述方法还可以包括:所述通信设备获取所述网络侧设备为第二目标成员载波组激活或指示的第二公共TCI状态信息,其中,所述第一公共TCI状态信息与所述第二公共TCI状态信息为不同的公共TCI状态信息,所述第二公共TCI状态信息包括第二功控参数标识,或者,所述第二公共TCI状态信息关联第二功控参数标识,所述第二目标成员载波组为所述至少一组成员载波中除所述第一目标成员载波组之外的一组成员载波;根据所述第二公共TCI状态信息,确定所述第二目标成员载波组中各个所述目标单元的目标功控参数。
在上述可能的实现方式中,可选地,通信设备可以采用上述与确定第一目标成员载波组中的各个所述目标单元的目标功控参数相同的方式来确定第二目标成员载波组中各个所述目标单元的目标功控参数。在这种情况下,第一公共TCI状态信息与第二公共TCI状态信息可以相同,也可以不同,网络侧设备可以分别指示或激活第一目标成员载波组和第二目标成员载波组的公共TCI状态信息,并分别配置第一公共TCI状态信息和第二公共TCI状态信息包括或关联的功控参数标识。
例如,网络为各组CC分别独立指示common TCI state ID,且也根据上述步骤中的方式为各组CC分别独立配置PLRS。common TCI state ID和PLRS ID之间的关系同前,即在common TCI state中包括或者关联PLRS ID,或者common TCI state ID中包括或者关联PLRS ID。例如,第一组CC使用common TCI state 1,其中包含了PLRS 1,第二组CC使用common TCI state 2,其中 包含了PLRS 2。
可选地,所述第一功控参数标识和所述第二功控参数标识相同,在这种情况下,网络侧设备可以独立指示各个成员载波组的公共TCI状态信息,统一配置各个成员载波组的公共TCI状态信息包含或关联的功控参数标识。例如,网络为各组CC分别独立指示common TCI state ID,但PLRS ID相同。
在上述可能的实现方式中,所述第一目标成员载波组和所述第二目标成员载波组中每个成员载波组内的各个所述目标单元的目标功控参数为同一个公共功控参数,或者,每个成员载波组内各个所述目标单元的目标功控参数是分别确定的。
可选地,所述第一目标成员载波组的各个所述目标单元的目标功控参数和所述第二目标成员载波组的各个所述目标单元的目标功控参数为同一个公共功控参数。
例如,每组CC/BWP中,每个CC/BWP的PLRS可以为一个公共PLRS,或者为不同但却是QCL的PLRS。各组CC中,每个CC/BWP的PLRS也可以为一个公共PLRS,或者为不同但却是QCL的PLRS。
再例如,每组CC/BWP中,每个CC/BWP的PC setting中的功控参数可以为相同的功控参数。各组CC中,每个CC/BWP的PC setting中的功控参数也可以为相同的。

在上述可能的实现方式中,可选地,所述第一公共TCI状态信息包括或关联多个功控参数标识,每个所述功控参数标识对应一组成员载波的目标单元,或者,每个所述功控参数标识对应所述至少一组成员载波中的一个目标单元。
例如,在公共TCI state中包括或者关联的PLRS ID,或者在common TCI  state ID中包括或者关联的PLRS ID,分别对应着每组CC/BWP,或者对应着每个CC/BWP。根据预设排列或者位置,PLRS ID与每组CC/BWP或每个CC/BWP相互对应。若PLRS ID与每组CC/BWP相对应,则在该组CC/BWP中的每个CC/BWP都对应相同的PLRS ID。
再例如,在公共TCI state中包括或者关联的PC setting ID,或者在common TCI state ID中包括或者关联的PC setting ID,分别对应着每组CC/BWP,或者对应着每个CC/BWP。根据预设排列或者位置,PC setting ID与每组CC/BWP或每个CC/BWP相互对应。若PC setting ID与每组CC/BWP相对应,则在该组CC/BWP中的每个CC/BWP都对应相同的PC setting ID。
在上述可能的实现方式中,可选地,所述第一公共TCI状态信息包括或关联一个功控参数标识,各组所述成员载波的目标单元均对应所述一个功控参数标识。
例如,网络为各组CC指示相同的common TCI state ID,且在公共TCI state信息中包括或者关联的PLRS ID也相同,即PLRS ID用于各组CC中的每个CC/BWP。
通过本申请实施例提供的技术方案,在CA场景中网络侧设备指示了common TCI state的情况下,根据其中包括或关联的功控参数信息,来确定每个CC上的功控参数,使得网络和UE能够正确确定CA场景中各CC上的功控参数,保证功率控制的准确性。
