步骤S102、根据第一同相正交信号的功率变化量分别控制第一射频收发器和第二射频收发器中对功率进行调整的增益，以使得第一同相正交信号的功率相对于第二同相正交信号的功率维持不变，以及第一天线与第二天线之间的链路增益维持不变。
本实施方式中，第一天线接收的信号经过第一射频收发器和第二射频收发器处理之后，通过第二天线发送出去。其中，第一射频收发器和第二射频收发器均用于对接收信号的功率进行调整，例如增大或者减小。第一天线与第二天线之间的链路增益为第一射频收发器中对功率进行调整的增益与第二射频收发器中对功率进行调整的增益之和。
在步骤S102的具体实施中，基带芯片通过向第一射频收发器写入控制字的方式实现控制第一射频收发器中对功率进行调整的增益，通过向第二射频收发器写入控制字的方式实现控制第二射频收发器中对功率进行调整的增益。
在可选的一种实施方式中，步骤S102具体包括：
步骤S1021、将第一射频收发器中对功率进行调整的增益更新为减去第一同相正交信号的功率变化量。
步骤S1022、将第二射频收发器中对功率进行调整的增益更新为加上第一同相正交信号的功率变化量。
本实施方式中，第一同相正交信号的功率变化量可能为正数，即第一同相正交信号的功率相对于第二同相正交信号的功率变大；第一同相正交信号的功率变化量也可能为负数，即第一同相正交信号的功率相对于第二同相正交信号的功率变小。在具体实施中，步骤S1021和S1022中增益的单位为dBm，在与第一同相正交信号的功率变化量进行加/减运算的时候需要根据公式：dBm＝10log(功率值/1mW)进行单位换算。
在一个下行场景的具体例子中，如图3所示，第一天线用于接收基站的信号，其功率为Pin1，经过第一射频收发器的处理之后输出同相正交IQ信号，其功率为Piq1，再经过第二射频收发器的处理之后输出第一发送信号，其功率为Pout1，第一发送信号经过第二天线发射出去，以供用户终端接收。本实施例中的中继放大系统为线性系统，假设第一天线当前接收的子帧相对于前一子帧的信号功率Pin1变化了ΔU1，基带芯片通过第一射频收发器输出的同相正交IQ信号检测到Piq1也相应变化了ΔU1。为了使得第一同相正交信号的功率相对于第二同相正交信号的功率维持不变，即使得Piq1维持不变，以及第一天线与第二天线之间的下行链路增益GU1维持不变，基带芯片控制第一射频收发器中对功率进行调整的增益从Gagc更新为Gagc-ΔU1，控制第二射频收发器中对功率进行调整的增益从Gapc更新为Gapc+ΔU1。此时，Piq1＝(Pin1+ΔU1)+(Gagc-ΔU1)＝Pin1+Gagc，下行链路增益GU1＝(Gagc-ΔU1)+(Gapc+ΔU1)＝Gagc+Gapc，Pou1＝(Pin1+ΔU1)+GU1。本实施例中，通过控制同相正交IQ信号的功率Piq1以及下行链路增益GU1维持不变，使得第一天线接收的输入信号的功率变化量ΔU1转移到输出至输出信号上。
在可选的一种实施方式中，上述中继放大方法还包括以下步骤：
步骤S103、若第二射频收发器输出至第二天线的第一发送信号的功率达到额定功率，则根据第一同相正交信号的功率变化量控制第一射频收发器和/或第二射频收发器中对功率进行调整的增益，以使得所述第一发送信号的功率维持在额定功率。本实施方式中，可以通过仅控制第一射频收发器中对功率进行调整的增益，以使得第一发送信号的功率维持在额定功率，也可以通过仅控制第二射频收发器中对功率进行调整的增益，以使得第一发送信号的功率维持在额定功率，还可以同时控制第一射频收发器和第二射频收发器中对功率进行调整的增益，以使得第一发送信号的功率维持在额定功率。
在可选的一种实施方式中，若第一发送信号的功率增大至额定功率，则首先控制第一射频收发器中对功率进行调整的增益，以使得第一发送信号的功率维持在额定功率。若无法通过仅控制第一射频收发器中对功率进行调整的增益使得第一发送信号的功率维持在额定功率，则同时控制第二射频收发器中对功率进行调整的增益。
在上述下行场景的一个具体例子中，第一天线接收的前一子帧的功率Pin1导致第二射频收发器输出至第二天线的第一发送信号的功率达到额定功率，即Pout1＝Pin1+GU1＝P额定。假设第一天线当前接收的子帧相对于前一子帧的信号功率Pin1变化了ΔU1’，即第一同相正交信号的功率变化量为ΔU1’，通过控制第一射频收发器中对功率进行调整的增益从Gagc更新为Gagc-ΔU1’，第二射频收发器中对功率进行调整的增益Gapc维持不变，得到Pout1＝(Pin1+ΔU1’)+GU1-ΔU1’＝Pin1+GU1＝P额定，即将Pout1维持在额定功率。本实施例中，通过将下行链路增益GU1压缩ΔU1’，使得第一发送信号的功率即输出功率维持在额定功率。
在可选的一种实施方式中，上述中继放大方法还包括以下步骤：
步骤201、判断第二射频收发器输出的第三同相正交信号的功率相对于第四同相正交信号的功率是否发生变化，若是，则执行步骤S202，若否，则继续执行步骤S201。
其中，第三同相正交信号为与第二天线接收的当前子帧对应的同相正交IQ信号，第四同相正交信号为与第二天线接收的前一子帧对应的同相正交IQ信号。在具体实施中，第二天线接收的信号由一个一个的子帧组成。
步骤S202、根据第三同相正交信号的功率变化量分别控制第二射频收发器和第一射频收发器中对功率进行调整的增益，以使得第三同相正交信号的功率相对于第四同相正交信号的功率维持不变，以及第一天线与第二天线之间的链路增益维持不变。
本实施方式中，第二天线接收的信号经过第二射频收发器和第一射频收发器处理之后，通过第一天线发送出去。其中，第一射频收发器和第二射频收发器均用于对接收信号的功率进行调整，例如增大或者减小。
在可选的一种实施方式中，步骤S202具体包括：
步骤S2021、将第二射频收发器中对功率进行调整的增益更新为减去第三同相正交信号的功率变化量。
步骤S2022、将第一射频收发器中对功率进行调整的增益更新为加上第三同相正交信号的功率变化量。
本实施方式中，第三同相正交信号的功率变化量可能为正数，即第三同相正交信号的功率相对于第四同相正交信号的功率变大；第三同相正交信号的功率变化量也可能为负数，即第三同相正交信号的功率相对于第四同相正交信号的功率变小。在具体实施中，步骤S2021和S2022中增益的单位为dBm，在与第三同相正交信号的功率变化量进行加/减运算的时候需要根据公式：dBm＝10log(功率值/1mW)进行单位换算。
在一个上行场景的具体例子中，如图4所示，第二天线用于接收用户终端的信号，其功率为Pin2，经过第二射频收发器的处理之后输出同相正交IQ信号，其功率为Piq2，再 经过第一射频收发器的处理之后输出第二发送信号，其功率为Pout2，第二发送信号经过第一天线发送出去，以供基站接收。本实施例中的中继放大系统为线性系统，假设第二天线当前接收的子帧相对于前一子帧的信号功率Pin2变化了ΔU2，基带芯片通过第二射频收发器输出的同相正交IQ信号检测到Piq2也相应变化了ΔU2。为了使得第三同相正交信号的功率相对于第四同相正交信号的功率维持不变，即使得Piq2维持不变，以及第一天线与第二天线之间的上行链路增益GU2维持不变，基带芯片控制第二射频收发器中对功率进行调整的增益从Gagc更新为Gagc-ΔU2，控制第一射频收发器中对功率进行调整的增益从Gapc更新为Gapc+ΔU2。此时，Piq2＝(Pin2+ΔU2)+(Gagc-ΔU2)＝Pin2+Gagc，上行链路增益GU2＝(Gagc-ΔU2)+(Gapc+ΔU2)＝Gagc+Gapc，Pou2＝(Pin2+ΔU2)+GU2。本实施例中，通过控制同相正交IQ信号的功率Piq2以及上行链路增益GU2维持不变，使得第二天线接收的输入信号的功率变化量ΔU2转移到输出至输出信号上。
在可选的一种实施方式中，所述中继放大方法还包括以下步骤：
步骤S203、若第一射频收发器输出至第一天线的第二发送信号的功率达到额定功率，则根据第三同相正交信号的功率变化量控制第一射频收发器和/或第二射频收发器中对功率进行调整的增益，以使得所述第二发送信号的功率维持在额定功率。本实施方式中，可以通过仅控制第一射频收发器中对功率进行调整的增益，以使得第二发送信号的功率维持在额定功率，也可以通过仅控制第二射频收发器中对功率进行调整的增益，以使得第二发送信号的功率维持在额定功率，还可以同时控制第一射频收发器和第二射频收发器中对功率进行调整的增益，以使得第二发送信号的功率维持在额定功率。
在可选的一种实施方式中，若第二发送信号的功率增大至额定功率，则首先控制第二射频收发器中对功率进行调整的增益，以使得第二发送信号的功率维持在额定功率。若无法通过仅控制第二射频收发器中对功率进行调整的增益使得第二发送信号的功率维持在额定功率，则同时控制第一射频收发器中对功率进行调整的增益。
在上述上行场景的一个具体例子中，第二天线接收的前一子帧的功率Pin2导致第一射频收发器输出至第一天线的第二发送信号的功率达到额定功率，即Pout2＝Pin2+GU2＝P额定。假设第二天线当前接收的子帧相对于前一子帧的信号功率Pin2变化了ΔU2’，即第三同相正交信号的功率变化量为ΔU2’，通过控制第二射频收发器中对功率进行调整的增益从Gagc更新为Gagc-ΔU2’，第一射频收发器中对功率进行调整的增益Gapc维持不变，得到Pout2＝(Pin2+ΔU2’)+GU2-ΔU2’＝Pin2+GU2＝P额定，即将Pout2维持在额定功率。本实施例中，通过将上行链路增益GU2压缩ΔU2’，使得第二发送信号的功率即输出功率维持在额定功率。
