天线校准方法、装置及基站Antenna calibration method, device and base station

技术领域technical field

本发明实施例涉及无线通信技术,尤其涉及一种天线校准方法、装置及基站。Embodiments of the present invention relate to wireless communication technologies, and in particular, to an antenna calibration method, apparatus, and base station.

背景技术Background technique

在无线通信系统中,对于时分双工(Time Division Duplexing,简称:TDD)基站系统,由于上行链路和下行链路使用相同的载频,理论上可认为上行物理传播信道和下行物理传播信道具有互易性。但是在实际实现过程中,每根天线的射频端需要两套电路来分别完成信号的发送和接收。由于硬件方面的工艺误差,放大器的非线性失真,以及工作频率、时间以及外部环境(如温度、湿度等)等因素对每个射频电路的特征响应的影响,很难实现射频端的两套电路具有完全一致的特性。因此,对于基带信号来说,发送通道和接收通道等效地对信道乘以不同的系数,导致了信道的互易性受损。为了消除各个射频端接收通道和发送通道之间的偏差对信道的影响,保证射频通道的互易性,需要对射频通道进行校准,以保证多个远端射频模块(Radio Remote Unit,简称:RRU)的射频端发送通道幅度和相位的一致性。In a wireless communication system, for a Time Division Duplexing (TDD) base station system, since the uplink and downlink use the same carrier frequency, it can theoretically be considered that the uplink physical propagation channel and the downlink physical propagation channel have the same carrier frequency. reciprocity. However, in the actual implementation process, the radio frequency end of each antenna needs two sets of circuits to respectively complete the signal transmission and reception. Due to the process error of the hardware, the nonlinear distortion of the amplifier, and the influence of the operating frequency, time, and external environment (such as temperature, humidity, etc.) on the characteristic response of each RF circuit, it is difficult to realize that the two sets of circuits at the RF end have Fully consistent feature. Therefore, for a baseband signal, the transmit channel and the receive channel are equivalently multiplied by different coefficients for the channel, resulting in impaired reciprocity of the channel. In order to eliminate the influence of the deviation between the receiving channel and the transmitting channel of each RF end on the channel and ensure the reciprocity of the RF channel, the RF channel needs to be calibrated to ensure that multiple remote RF modules (Radio Remote Unit, RRU for short) ) of the RF side transmit channel amplitude and phase consistency.

现有技术中,对射频通道进行校准的方法是:基站系统通过参考发射通道向各个射频端发送相同的接收通道校正序列,基站系统的各个接收通道接收到该接收通道校正序列后根据该接收通道校正序列计算对应的接收通道的校正系数,并根据该校正系数对所述对应的接收通道进行幅度相位校准。In the prior art, the method for calibrating the radio frequency channel is as follows: the base station system sends the same receive channel correction sequence to each radio frequency terminal by referring to the transmit channel, and each receive channel of the base station system receives the receive channel correction sequence according to the receive channel correction sequence. The correction sequence calculates the correction coefficient of the corresponding receiving channel, and performs amplitude and phase calibration on the corresponding receiving channel according to the correction coefficient.

由于射频通道校准过程是根据基站系统接收到的接收通道校正序列来完成的,如果校准时刻,所述基站系统的接收通道还接收到其它外部信号输入,例如UE发送上行信号,会导致基站接收通道中校准序列的信噪比下降,导致校准精度降低甚至校准失败。Since the radio frequency channel calibration process is completed according to the receive channel correction sequence received by the base station system, if the receive channel of the base station system also receives other external signal inputs at the time of calibration, for example, the UE sends an uplink signal, it will cause the base station receive channel The signal-to-noise ratio of the calibration sequence decreases, resulting in a decrease in the calibration accuracy or even failure of the calibration.
