Description
Technical Field
The present application relates to the field of mobile communications technologies, and in particular, to a base station power threshold alarm method and apparatus.
Background
In a wireless communication system, a radio frequency signal at a transmitting end of a base station is transmitted to an antenna, and is transmitted from the antenna in the form of a high frequency electromagnetic wave. After passing a certain distance, the high-frequency electromagnetic wave reaches the terminal position and is received by a receiving antenna of the terminal, and then is transmitted to a receiving end of the terminal for processing. On the contrary, the radio frequency signal from the terminal transmitting end is reversely processed according to the flow and transmitted to the base station receiving end.
Too much transmit power of the base station and the terminal may cause interference, and too little receive power of the base station and the terminal may affect demodulation, which directly affects performance of the wireless communication system. In a practical system, each terminal uses a lower signal level to transmit data under the condition of meeting a certain signal-to-noise ratio so as to control the adverse effect of the transmitting power on the communication system. In order to limit the power of the transmitting signal in the expected range on the premise of ensuring the communication quality of the wireless communication system, the base station needs to compensate the unreasonable gain generated by the transmitting signal in each link, so as to avoid the problem that the wireless communication system cannot demodulate correctly when the uplink receiving power is too low or the downlink transmitting power is too high.
Therefore, the base station needs to check the uplink receiving power and the downlink transmitting power, so as to avoid that the performance of the wireless communication system is affected due to the fact that the uplink receiving power is too low or the downlink transmitting power is too high.
