对任一目标上行信道或信号：
当所述目标上行信道或信号的空域关系关联的参考信号为下行信号时，将所述目标上行信道或信号的空域关系关联的参考信号作为所述目标上行信道或信号传输功率控制的路损参考信号。
在一实施例中，所述空域关系参数包括空域关系关联的参考信号；
所述步骤203中，根据所述上行传输空域关系参数确定用于上行传输功率控制的路损参考信号包括：包括：
对任一目标上行信道或信号，当所述目标上行信道或信号的空域关系关联的参考信号非下行信号时，将与所述目标上行信道或信号通过多级空域关系关联且为下行信号的第N参考信号作为所述目标上行信道或信号传输功率控制的路损参考信号，其中，所述通过多级空域关系关联是指所述目标上行信道或信号与所述第N参考信号之间存在N-1级参考信号，且N>1，从所述目标上行信道或信号开始，每级与其下一级通过空域关系关联。假设N＝2，即目标上行信道或信号的路损参考信号为其第二参考信号，目标上行信道或信号与第二参考信号之间包括一级参考信号，称为第一参考信号，目标上行信道或信号与第一参考信号通过空域关系关联，第一参考信号与第二参考信号通过空域关系关联； 又比如，目标上行信道或信号到第N参考信号之间包括N-1级参考信号，依次为第一级至第N-1级，其中，目标上行信道或信号与第一级参考信号之间通过空域关系关联，第一级参考信号与第二级参考信号之间通过空域关系关联，依次类推，第N-1级参考信号与第N级参考信号(即第N参考信号)之间通过空域关系关联。

上行解调参考信号(Uplink demodulation reference signal，UL DMRS)；
相位追踪参考信号(Phase-tracking reference signal，PTRS)。
举例来说，目标上行信道为PUCCH，从RRC Setup信令中获取PUCCH的空域关系参数，获取到PUCCH关联的参考信号为CSI-RS#1，表示CSI-RS resource Id(资源标识)为1的CSI-RS信号，且CSI-RS#1为下行信号，则将所述PUCCH关联的参考信号CSI-RS#1作为用于该PUCCH传输功率控制的路损参考信号；
图3为本发明一实施例提供的终端根据所述目标上行信道或信号的空域关系关联的参考信号确定用于上行传输功率控制的路损参考信号的方法流程图。
为了描述清晰，本步骤定义若干个节点，每个节点代表一个信号，节点之间通过空域关系进行关联，具体地，父节点信号的空域关系关联的参考信号为该父节点的子节点信号。目标上行信道或信号定义为根节点，目标上行信道或信号的空域关系关联的参考信号所在的节点为所述根节点的子节点，该根节点 也是该子节点的父节点，所述子节点同样存在与其通过空域关系关联的子节点，即父节点的空域关系关联的参考信号为该父节点的子节点。每一个节点具有各自的节点索引值i，定义所述目标上行信道或信号的索引为0，子节点的节点索引值为其父节点的节点索引值加1。需要说明的是，此定义仅为示例，可以根据需要设置其他节点索引值。
本步骤中，终端从根节点开始，按照父节点向子节点的方向，遍历每个节点，直至找到某节点的空域关系关联的参考信号为下行信号，则将该下行信号作为所述上行传输功率控制的路损参考信号，并结束遍历。
如图3所示，包括：
步骤301：将节点索引值i置为0，表示根节点；
步骤302：判断节点i的空域关系关联的参考信号是否为下行信号，如果是下行信号，则进入步骤304；如果不是下行信号，进入步骤303；
步骤303：将节点索引值i变为i+1，返回步骤302；
步骤304，确定所述上行信道或信号的路损参考信号为节点i的空域关系关联的参考信号，结束。
本实施例中，所述终端确定路损参考信号的方法复用上行传输控制信令中的空域关系参数，以实现目标上行传输信道或信号与其路损参考信号的波束关系进行绑定，当发生波束切换时，目标上行传输信道或信号的路损参考信号的波束关系进行同步切换，且无需额外的信令指示。
示例性的，图4、图5、图6为确定路损参考信号的三个示例。
如图4所示，对于PUCCH传输，该PUCCH信号为根节点41(该节点索引值i＝0)，其空域关系关联的参考信号为CSI-RS#2(表示CSI-RS resource Id(资源标识)＝2的CSI-RS信号)，即节点42(该节点索引值i＝1)，该参考信号为下行信号，则终端指示CSI-RS#2为该PUCCH传输功率控制的路损参考信 号。
如图5所示，对于PUSCH传输，该PUSCH信号为根节点51(该节点索引值i＝0)，其空域关系关联的参考信号为SRS#1(表示SRS resource Id＝1的SRS信号)，该参考信号为上行信号，则终端向其子节点，即节点52(该节点索引值i＝1)遍历，节点52即为第一参考信号，节点52(SRS#1)的空域关系关联的参考信号为CSI-RS#5(节点53，该节点索引值i＝2)，节点53即为第二参考信号，该参考信号为下行信号，则CSI-RS#5为该PUSCH信道传输功率控制的路损参考信号。本实施例中，将第二参考信号作为路损参考信号，目标上行信道与路损参考信号通过两级空域关系关联，其中间存在一级参考信号(即第一参考信号)。
需要说明的是，PUSCH的空域关系参数(PUSCH关联的参考信号)和SRS的空域关系参数(SRS关联的参考信号)可以在不同的上行传输控制信令中携带，比如一个在DCI中携带，一个在RRC Setup信令中携带。
如图6所述，对于SRS传输，该SRS信号为根节点61(该节点索引值i＝0)，其空域关系关联的参考信号为CSI-RS#2(节点62，该节点索引值i＝1)，该参考信号为下行信号，则CSI-RS#2为该SRS信号传输功率控制的路损参考信号。
