具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
参见图1，图1是本公开的一些实施例可应用的网络结构示意图，如图1所示，包括终端11和网络侧设备12，终端11可以是用户终端(User Equipment，UE)或者其他终端设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)、机器人、车辆等终端侧设备，需要说明的是，在本公开的一些实施例中并不限定终端的具体类型。网络侧设备12可以是基站，例如：宏站、LTE eNB、5G NR NB等；网络侧设备也可以是小站，如低功率节点(Low Power Node，LPN)、pico、femto等小站，或者网络侧设备可以接入点(Access Point，AP)；网络侧设备也可以是中央单元(Central Unit，CU)，或者可以是传输接收点(Transmission Reception Point，TRP)等网络节点。需要说明的是，在本公开的一些实施例中并不限定网络侧设备的具体类型。
请参见图2，图2是本公开的一些实施例提供的一种功率控制参数配置 方法的流程图，如图2所示，包括以下步骤：
201、终端获取网络侧设备指示的发送上行信号的准共址(Quasi Co-Location，QCL)关系；
202、所述终端确定所述准共址关系对应的功率控制参数和路损参考导频中的至少一项，其中，所述功率控制参数与所述准共址关系的大尺度信息关联，所述路损参考导频与所述准共址关系的参考信号关联；
203、依据所述功率控制参数和路损参考导频中的至少一项确定上行发送功率，并依据所述上行发送功率发送所述上行信号。
本公开的一些实施例中，传输配置指示(transmission configuration indication，TCI)状态可以用于配置准共址关系，或者，准共址关系可以由TCI状态配置。因此，本公开的一些实施例中，准共址关系也可以称作或者理解为传输配置指示状态(TCI state)或者准共址状态。
另外，上述获取准共址关系可以是接收网络侧配置的准共址关系，例如：通过配置信息配置上述准共址关系。
上述发送上行信号的准共址关系可以是，发送上行信号时的准共址关系。
而上述确定所述准共址关系对应的功率控制参数和路损参考导频可以是，根据网络侧指示确定的功率控制参数和路损参考导频，例如：网络侧指示功率控制参数的标识或者功率控制参数等功率控制信息，从而终端通过这些功率控制信息确定上述功率控制参数和路损参考导频。当然，本公开的一些实施例中，并不限定上述功率控制参数和路损参考导频是由网络侧指示的，例如：在一些实施方式中，可以实现终端预先有多个准共址关系对应的功率控制参数和路损参考导频，从而终端在获取到准共址关系，可以确定对应的功率控制参数和路损参考导频。
需要说明的是，步骤202和步骤203中的至少一项是指相同的内容，即步骤202确定功率控制参数和路损参考导频，那么步骤203就依据功率控制参数和路损参考导频确定上行发送功率，若步骤202确定功率控制参数或者路损参考导频，那么步骤203就依据功率控制参数或者路损参考导频确定上行发送功率。另外，如果步骤202确定功率控制参数，则确定上行发送功率所使用的路损参考导频可以使用协议中已定义的路损参考导频，同理，如果 步骤202确定路损参考导频，则确定上行发送功率所使用的功率控制参数可以使用协议中已定义的功率控制参数，这样相比相关技术，同样可以提高上行传输的性能。
需要说明的是，上述功率控制参数与所述准共址关系的大尺度信息关联，以及路损参考导频与所述准共址关系的参考信号关联可以是理解为，上述功率控制参数是依据准共址关系的大尺度信息确定的，上述路损参考导频是依据准共址关系的参考信号(Reference Signal)确定的。例如：网络侧依据准共址关系的参考信号确定上述路损参考导频，依据准共址关系的大尺度信息确定上述功率控制参数。
而上述大尺度信息可以包括但不限于如下至少一项：
路损、时延扩展、平均时延、多普勒扩展、多普勒偏移、平均增益以及空间接收参数等。
具体的，上述大尺度信息可以是协议中已定义或者新定义的大尺度信息，
该实施方式中，由于路损参考导频与所述准共址关系的参考信号关联，这样可以实现根据每个准共址关系的参考信号指示的信道状态进行功率控制，更好的进行上行传输；以及由于功率控制参数与所述准共址关系的大尺度信息关联，这样可以实现根据每个准共址关系的大尺度信息进行功率控制，更好的进行上行传输。
其中，上述路损参考导频可以是用于计算路损的导频，而路损和上述功率控制参数可以是上行功率控制公式中包括的参数，也就是说，本公开的一些实施例中，功率控制参数和路损参考导频是用于计算上行发送功率的部分或者全部参数。另外，
需要说明的是，本公开的一些实施例中，并不限定依据所述功率控制参数和路损参考导频中的至少一项确定上行发送功率，例如：可以采用协议中已定义的功率控制公式确定上行发送功率，或者可以是采用后续协议版本新定义的功率控制公式确定上行发送功率，对此不作限定。且上行功率控制公式可以是指PUSCH、PUCCH和SRS的功率控制公式中的至少一项。
本公开的一些实施例中，通过上述步骤可以实现为准共址关联配置对应的功率控制参数和路损参考导频，从而可以根据每个准共址关系对应功率控 制参数和路损参考导频进行功率控制，以更好地进行上行传输，进而提高上行传输的性能。例如：在进行该准共址关系的上行传输时，使用对应的功率控制参数进行传输，如使用上述功率控制参数发送上述上行信号。
一个例子可以是：网络侧根据准共址关系的信道信息，确定为该准共址关系配置相应的功率控制参数，网络侧指示终端发送上行信号时的准共址关系，终端根据网络侧指示的准共址关系，确定该准共址关系的功率控制参数，并进行相应上行信号的发送。
作为一种可选的实施方式，在所述准共址关系的参考信号为下行导频的情况下，所述路损参考导频为所述下行导频；或者
在所述准共址关系的参考信号为上行导频的情况下，所述路损参考导频为所述上行导频的准共址下行导频。
例如：可以为每个准共址关系配置一个参考信号，该参考信号可以是下行导频，也可以是上行导频。当准共址关联的参考信号是下行导频时，则功率控制参数中的路损参考导频即为该导频，不再额外配置对应的路损参考导频。当准共址关系的参考信号为上行导频(例如：SRS)时，网络侧设备可以将路损参考导频配置为该上行导频的准共址下行导频。
其中，上述上行导频的准共址下行导频可以是理解为，与该上行导频存在准共址关系的下行导频。
该实施方式中，通过这种配置，可以使路损估计与实际信号发送时的信道状态最匹配，功率控制更准确。
作为一种可选的实施方式，上述功率控制参数包括如下至少一项：
路损补偿因子和目标接收功率。
其中，这里的路损补偿因子和目标接收功率可以是上行功率控制公式中的路损补偿因子和目标接收功率。
上述路损补偿因子和目标接收功率是与准共址关系有关的功率控制参数，这样只配置与准共址关系有关的功率控制参数，从而可以降低复杂度。
可选的，在所述大尺度信息的路损为第一路损的情况下：所述路损补偿因子为第一路损补偿因子，所述目标接收功率为第一目标接收功率，或者，所述路损补偿因子为第二路损补偿因子，所述目标接收功率为第二目标接收 功率；
在所述大尺度信息的衰落为第二路损的情况下，所述路损补偿因子为第三路损补偿因子，所述目标接收功率为第三目标接收功率；
其中，所述第一路损大于所述第二路损，所述第一路损补偿因子大于所述第三路损补偿因子，所述第一目标接收功率大于所述第三目标接收功率，所述第二路损补偿因子小于所述第三路损补偿因子，所述第二目标接收功率小于所述第三目标接收功率。
该实施方式中，每个准共址关系可以对应一个大尺度信息的路损，另外，上述大尺度信息的路损也可以理解为大尺度信息的大尺度衰落。
该实施方式中，由于第一路损大于第二路损，第一路损补偿因子大于第三路损补偿因子，第一目标接收功率大于第三目标接收功率，这样可以实现路损比较大时，终端处于网络的边缘，是边缘用户，则为了用户的上行传输质量，可以将路损补偿因子和目标接收功率设置的大一些，以提高边缘用户的上行传输质量。以及可以实现，当路损比较小时，终端处于网络的中心，是中心用户，考虑到终端的节能，可以降低路损补偿因子和目标接收功率，以节约终端的功率。
另外，由于可以配置第二路损补偿因子和第二目标接收功率，且第二路损补偿因子小于第三路损补偿因子，第二目标接收功率小于第三目标接收功率，这样可以实现降低整个网络的干扰，对于边缘用户，即降低边缘用户路损补偿因子和目标接收功率，具体网络侧可以根据需要调整。
该实施方式中，可以通过为准共址关系配置合适的功率控制参数，以提高系统性能。
作为一种可选的实施方式，所述功率控制参数为所述准共址关系的配置信息中携带的功率控制参数；或者
所述功率控制参数为将所述准共址关系的配置信息中的功率控制参数与所述终端保存的功率控制参数进行第一运算，以得到的功率控制参数。
其中，上述配置信息可以理解为配置上述准共址关系的配置信息，例如：高层信令，如RRC信令。
上述第一运算可以是相加，当然，对此不作限定，例如：在一些实施方 式中，也是配置成相减或者其他运算。
其中，所述功率控制参数可以包括如下至少一项的功率控制参数：
PUCCH、PUSCH和SRS；
其中，所述配置信息中所述PUCCH、所述PUSCH和所述SRS中至少一项的功率控制参数独立配置，或者所述配置信息中所述PUCCH、所述PUSCH和所述SRS中至少一项的功率控制参数为统一配置的功率控制参数。
例如：RRC在配置准共址关系时，同时在准共址关系中配置该准共址关系对应的功率控制参数，例如：准共址关系的大尺度信息对应的功率控制参数。具体可以是，通过MAC CE的准共址关系激活，以及DCI的准共址关系指示，终端可以获得上行传输的准共址关系以及对应的功率控制参数。
以上述第一运算为相加进行举例：对于SRS的P0，每次收到准共址关系指示(例如，通过TCI指示的准共址关系)之后与终端保存的P0值加和得到更新的P0值，而对于PUCCH和PUSCH，每次收到准共址关系指示(例如，通过TCI指示的准共址关系)之后根据准共址关系中的P0值和配置的通用路损补偿因子(P0-normal)值加和得到功率控制公式中的P0，其中，P0表示上述目标接收功率。
上述PUCCH、所述PUSCH和所述SRS中至少一项的功率控制参数独立配置可以是，PUCCH、所述PUSCH和所述SRS的功率控制参数是分别配置的，例如：
PathlossReferenceRS-Id为PUSCH-PathlossReferenceRS-Id
PathlossReferenceRS-Id为PUCCH-PathlossReferenceRS-Id
P0-AlphaSetId为P0-PUSCH-AlphaSetId；
其中，PathlossReferenceRS表示路损参考导频。
而上述PUCCH、所述PUSCH和所述SRS中至少一项的功率控制参数为统一配置的功率控制参数可以是，为终端配置多个统一的路损参考导频(PathlossReferenceRS)和路损补偿因子(P0-AlphaSet)，不在区分PUCCH、PUSCH和SRS，如定义：
Figure PCTCN2020108379-appb-000001
Figure PCTCN2020108379-appb-000002
另外，在上行传输配置指示状态中配置功率控制信息的一种实现方式如下，每个上行传输配置指示状态配置一个准共址关系，以及该准共址关系对应的功率控制参数：
Figure PCTCN2020108379-appb-000003
Figure PCTCN2020108379-appb-000004
当上述referenceSignal为下行导频时，PathlossReferenceRS-Id可以不配置。
或者，在上行传输配置指示状态中直接配置功率相关的信息的一种实现方式如下，每个上行传输配置指示状态配置一个准共址关系，以及该准共址关系对应的功率控制参数：
Figure PCTCN2020108379-appb-000005
当上述referenceSignal为下行导频时，PathlossReferenceRS可以不配置。
上述实施方式中，由于PUCCH、所述PUSCH和所述SRS中至少一项 的功率控制参数为统一配置的功率控制参数，这样可以节约信令开销。
需要说明的是，本公开的一些实施例中，在准共址关联的参考信号为下行导频(例如：SSB或者CSI-RS)时，路损参考导频可以不配置，该下行参考导频可以作为路损参考导频。
作为一种可选的实施方式，所述功率控制参数为多个功率控制参数中标识对应的功率控制参数，所述标识包括所述准共址关系的配置信息配置的标识，所述多个功率控制参数为提前配置的。
其中，上述多个功率控制参数可以是用于多个准共址关系进行上行传输的功率控制参数，这样通过上述标识可以灵活地指示各准共址关系对应的功率控制参数。
例如：对于功率控制信息，已经提前配置了多个P0-AlphaSet和多个PathlossReferenceRS。网络侧设备可以根据准共址关系的大尺度信息，在准共址状态中配置相应的P0-Alpha ID和PathlossReferenceRS ID。
例如：关于P0-AlphaSet的配置如下：
对于PUSCH：
Figure PCTCN2020108379-appb-000006
其中，Alpha的取值为0，0.4，0.5，0.6，0.7，0.8，0.9，1.0等。
对于PUCCH：功率控制公式中可以没有alpha
Figure PCTCN2020108379-appb-000007
对于SRS：
alpha                        Alpha
p0                           INTEGER(-202..24)
可见，对于PUSCH和PUCCH，P0的取值是相同范围的，都是相对值，而SRS的P0是绝对值，这样，为了将上行的PUSCH，PUCCH，SRS都采用统一的配置流程，可以将与准共址关系关联的P0配置为相对值，例如：上述介绍的PUCCH、所述PUSCH和所述SRS中至少一项的功率控制参数为统一配置的功率控制参数的方式。
另外，可以通过RRC配置多个准共址功率控制参数(如QCL-PowerControl)，然后为每个准共址关系配置一个准共址功率控制参数ID。
例如：在一个QCL-PowerControl例子中，PathlossReferenceRS-Id，P0-PAlphaSetId可以参见上面实施方式的描述，该例子如下：
Figure PCTCN2020108379-appb-000008
例如：在另一个QCL-PowerControl例子中：
Figure PCTCN2020108379-appb-000009
然后在配置准共址关系时，可以为该准共址关系选择配置一个准共址功率控制参数。如下面一个可能的例子，每个上行传输配置指示状态配置一个 准共址关系，以及该准共址关系对应的功率控制参数：
Figure PCTCN2020108379-appb-000010
可选的，所述功率控制参数包括如下至少一项的功率控制参数：
PUCCH、PUSCH和SRS；
其中，所述PUSCH的功率控制参数的标识为所述配置信息配置的标识；
所述SRS的功率控制参数的标识为所述配置信息配置的标识，或者所述SRS的功率控制参数的标识为SRS请求中配置的标识；
所述PUCCH的功率控制参数的标识为所述配置信息、RRC或者MAC CE配置的标识。
该实施方式中，可以灵活地配置PUCCH、PUSCH和SRS的功率控制参数。例如：上行传输配置指示状态(例如，UL-TCI state)可以用于配置上行准共址关系(例如：UL QCL state)，可以用于配置PUSCH、SRS和PUCCH的功率控制参数，对于PUSCH，可以通过DCI中的UL TCI域指示；对于SRS，可以在DCI中增加SRS TCI域指示，结合SRS请求(SRS request)配置，指示SRS的发送，或者在RRC的SRS配置中指示TCI；对于PUCCH，可以通过DCI配置，也可以通过RRC或者MAC CE配置。
作为一种可选的实施方式，所述功率控制参数为DCI在功率控制参数集合中指示的功率控制参数，所述功率控制参数集合是提前配置给所述准共址关系的。
该实施方式中，可以为每个准共址关系配置一个功率控制参数集合，该功率控制参数集合可以包括一个或者多组功率控制参数，且不同的准共址关系的功率控制参数集合包括的功率控制参数的数量以及内容可以全部相同，部分相同或者不同。这样，可以灵活地配置每个准共址关系的功率控制参数，且由于每个准共址关系配置一个功率控制参数集合，从而为各准共址关系配置的功率控制参数更加匹配，以进一步提高上行传输的性能。
例如：网络侧设备为终端配置和激活多个准共址关系，每个准共址关系同时激活一个相应的功率控制参数集合，即在RRC IE PUSCH-PowerControl中配置和更新N个QCL-PowerControl，N的大小取决于DCI中准共址指示的bit数，如准共址指示的bit数为3时，N小于等于8
具体为：
Figure PCTCN2020108379-appb-000011
然后，可以通过DCI中的准共址指示PUSCH-PowerControl中配置的某个QCL-PowerControl。
又例如：准共址关系、路损参考信号和功率控制参数两两结合配置。当准共址中的参考信号为下行信号时，该参考信号同时可以作为路损参考信号。则通过DCI中为该准共址关系配置开环功率控制参数P0AlphaSet-Id(最多可以是5bit)和闭环调整状态(例如：1bit)，其中，闭环调整状态为上行功率控制公式中的闭环参数。
进一步的，网络侧设备可以决定是否更新功率控制参数，如果DCI中包括功率控制参数，则终端要更新，不需要额外指示更新功率控制参数。例如：对于P0AlphaSet-Id，如果DCI中没有配置，则终端使用已经配置的P0AlphaSet。例如：
Figure PCTCN2020108379-appb-000012
本公开的一些实施例，可以实现在配置上行准共址关系时，同时为该准共址关系配置相应的功率控制参数。
例如：网络侧设备通过高层信令为准共址关系配置功率控制参数；或者
网络侧设备通过物理层信令DCI为准共址关系配置功率控制参数。
由于本公开的一些实施例在配置上行准共址关系时，同时为该准共址关系配置相应的功率控制参数，从而可以根据每个准共址关系的功率控制参数进行功率控制，以获得更好的进行上行传输。
请参见图3，图3是本公开的一些实施例提供的一种功率控制参数配置方法的流程图，如图3所示，包括以下步骤：
