下面将结合两个具体实施例，详细介绍终端设备如何确定两个天线端口到网络设备的路径损耗差。
可选的，作为第一个实施例，在该方法100中的S210中，终端设备确定该第一天线端口到网络设备的路径损耗与该第二天线端口到该网络设备的路径损耗之间的路径损耗差可以包括：该终端设备根据该第一天线端口和该第二天线端口接收该网络设备发送的参考信号的接收功率，确定该路径损耗差。
具体地，网络设备向终端设备发送参考信号，该终端设备通过第一天线端口和第二天线端口接收该参考信号，其中，终端设备通过测量确定该第一天线端口接收到该参考信号时的参考信号接收功率(Reference Signal Receiving Power，RSRP)，这里将其记为第一RSRP；另外，终端设备还通过测量确定了第二天线端口接收到该参考信号时的RSRP，并记为第二RSRP。由于第一RSRP与第二RSRP为终端设备测量不同端口接收的同一参考信号的接收功率，因此，该终端设备可以将该第二RSRP与该第一RSRP的差，确定为该第一天线端口到网络设备的路径损耗与该第二天线端口到该网络设备的路径损耗之间的路径损耗差。
在该实施例中，该第一天线端口和第二天线端口可以为该终端设备可以包括的多个天线端口中的任意两个天线端口，或者，该第一天线端口和第二天线端口分别选择多个天线端口中路径损耗最大和最小的两个天线端口，本申请实施例并不限于此。
其中，若该第一天线端口和第二天线端口选择路径损耗最大和最小的两个天线端口，那么在该第一个实施例中，终端设备可以通过多个天线端口接收网络设备发送的参考信号，并确定每个天线端口的RSRP，并在其中选择最大的RSRP对应的天线端口和最小的RSRP分别作为第一天线端口和第二天线端口，例如，该第一天线端口的第一RSRP可以为多个天线端口的RSRP中的最小值，即该第一天线端口到网络设备的路径损耗最大；该第二天线端口的第二RSRP可以为该多个天线端口的RSRP中的最大值，即该第二天线端口到网络设备的路径损耗最小。
可选的，作为第二个实施例，在该方法100中的S210中，终端设备确定该第一天线端口到网络设备的路径损耗与该第二天线端口到该网络设备的路径损耗之间的路径损耗差可以包括：该终端设备接收该网络设备发送的指示信息，该指示信息用于指示该路径损耗差。
可选的，网络设备可以根据接收到的测量信号的强度，确定该路径损耗差，例如，终端设备通过第一天线端口和第二天线端口，采用相同的发射功 率向网络设备发送测量信号，网络设备测量接收到该两个天线端口发送的测量信号时的强度，确定路径损耗差。
具体地，该终端设备通过该第一天线端口，采用该相同发射功率向该网络设备发送第一测量信号；该终端设备通过该第二天线端口，采用该相同发射功率向该网络设备发送第二测量信号。网络设备测量接收到该第一测量信号时的接收功率为第一接收功率，测量接收到该第二测量信号时的接收功率为第二接收功率，则网络设备可以将该第二接收功率与该第一接收功率的差确定为该路径损耗差。网络设备向终端设备发送指示信息，该指示信息包括该路径损耗差，以便于终端设备根据该指示信息确定路径损耗差。
在该实施例中，该第一天线端口和第二天线端口可以为该终端设备可以包括的多个天线端口中的任意两个天线端口，或者，该第一天线端口和第二天线端口分别选择多个天线端口中路径损耗最大和最小的两个天线端口，本申请实施例并不限于此。
其中，若该第一天线端口和第二天线端口要选择路径损耗最大和最小的两个天线端口，可以由网络设备根据接收的测量信号的发射功率确定该第一天线端口和第二天线端口。那么在该第一个实施例中，终端设备可以通过包括的多个天线端口，采用相同的发射功率，均向网络设备发送测量信号，网络设备接收该多个天线端口发送的测量信号，确定与每个天线端口的测量信号对应的接收功率，选择其中接收功率最大值和最小值，并确定该最大值和最小值对应的天线端口，将该两个天线端口分别作为第一天线端口和第二天线端口。
例如，网络设备将接收功率最小值对应的天线端口作为第一天线端口，则该第一天线端口到网络设备的路径损耗最大；网络设备将接收功率最大值对应的天线端口作为第二天线端口，则该第二天线端口到网络设备的路径损耗最小，该网络设备将该第二天线端口对应的第二接收功率与第一天线端口对应的第一接收功率的差值作为路径损耗差。并且，该网络设备向终端设备发送的指示信息可以包括该路径损耗差，或者，该指示信息还可以包括该第一天线端口和第二天线端口的标识，以便于终端设备根据该指示信息，在多个天线端口中确定路径损耗最大的第一天线端口和路径损耗最小的第二天线端口。
在S220中，终端设备在确定了路径损耗差之后，可以根据该路径损耗差，确定第一天线端口和第二天线端口的发射功率，即调节两个天线端口的发射功率达到平衡。
为了便于说明，这里以该第一天线端口到该网络设备的路径损耗大于或者等于该第二天线端口到该网络设备的路径损耗为例进行说明。
在本申请实施例中，终端设备可以先确定该两个天线端口的总功率，这里将该总功率表示为P total。具体地，终端设备可以根据标准规定的功率控制过程，计算确定两个天线端口的总功率P total。该总功率P total用于：终端设备的第一天线端口的第一发射功率和第二天线端口的第二发射功率的总和小于 或者等于该总功率P total。
由于第一天线端口到该网络设备的路径损耗大于或者等于该第二天线端口到该网络设备的路径损耗，因此，在功率分配时，可以将更多的功率分配给路径损耗更大的第一天线端口。
具体地，终端设备为第一天线端口分配第一发射功率可以包括：该终端设备根据下面的公式(1)，确定第一功率P 1：
P 1＝[P total+|Δ PL|]/2       (1)
其中，P total表示该终端设备确定的该第一天线端口和该第二天线端口的总功率；|Δ PL|表示该路径损耗差的绝对值，例如，该路径损耗差可以为上面终端设备根据第一RSRP和第二RSRP的差值确定的，或者，该路径损耗差也可以为网络设备发送的。该终端设备再根据该第一功率P 1，确定该第一发射功率。
例如，若该第一功率P 1小于或者等于该第一天线端口的最大发射功率，将该第一发射功率确定为该第一功率P 1；或者，若该第一功率P 1大于该第一天线端口的最大发射功率，将该第一发射功率确定为该第一天线端口的最大发射功率。
可选的，终端设备确定了该第一发送功率后，可以再根据总功率P total减去该第一发射功率得到的差值，确定第二天线端口的第二发射功率。具体地，若总功率P total减去该第一发射功率得到的差值小于或者等于该第二天线端口的最大发射功率，则将该差值确定为该第二天线端口的第二发射功率；或者，若总功率P total减去该第一发射功率得到的差值大于该第二天线端口的最大发射功率，将该第二发射功率确定为该第二天线端口的最大发射功率。
可选的，终端设备也可以通过其他方式确定该第二天线端口的第二发射功率。具体地，该终端设备可以根据下面的公式(2)，确定第二功率P 2：
P 2＝[P total-|Δ PL|]/2       (2)
其中，与公式(1)相同，P total表示该终端设备确定的该第一天线端口和该第二天线端口的总功率；|Δ PL|表示该路径损耗差的绝对值，例如，该路径损耗差可以为上面终端设备根据第一RSRP和第二RSRP的差值确定的，或者，该路径损耗差也可以为网络设备发送的。该终端设备根据该第二功率P 2，确定该第二发射功率。
具体地，若该第二功率P 2小于或者等于该第二天线端口的最大发射功率，将该第二发射功率确定为该第二功率P 2；或者，若该第二功率P 2大于该第二天线端口的最大发射功率，将该第二发射功率确定为该第二天线端口的最大发射功率。
因此，本申请实施例的确定终端设备天线的发射功率的方法，对于终端设备采用多天线发射的情况，终端设备或者网络设备可以对不同发射端口的损耗进行测量，终端设备获取该测量结果，并根据该测量结果调整对应的天 线端口的发射功率强度，使得在网络设备端接收到的端口间信号强度保持相对平衡状态，增加上行吞吐量，也可以改善终端设备多天线间发射功率的平衡性，进而改善UL MIMO性能。
上文中结合图1至图2，从终端设备的角度详细描述了根据本申请实施例的确定终端设备天线的发射功率的方法，下面将结合图3，从网络设备的角度描述根据本申请实施例的用于终端设备确定天线发射功率的方法。
