- Embodiments of the present invention relate to the field of multi-carrier control, and in particular, to a multi-carrier control method, a multi-carrier peak clipping module, and a base station.
- GSM Global System for Mobile Communications
- GSM multi-carrier power sharing technology means: In a GSM network, not all time slots must be continuously full-power transmitting; for GSM multi-carrier base stations, the power amplifier can be used under the premise that the rated output power capability of the multi-carrier power amplifier is unchanged. The output power is power-distributed between multiple carriers to achieve over-matching of carrier power.
- the carrier power over-matching means that the sum of the maximum output power of the carrier configured in each multi-carrier channel of the multi-carrier power amplifier is greater than the rated output power of the multi-carrier power amplifier.
- the carrier power over-allocation technique can increase the output power of the time slots occupied by each carrier in the multi-carrier channel.

This makes it possible to increase the power transmission capability of a single carrier under the premise that the rated output power of the multi-carrier power amplifier is constant, which is equivalent to enhancing the network coverage radius and reducing the network construction cost.
- the output power of the multi-carrier power amplifier is too large, which will increase the power demand of the base station, and increase the heat consumption of the power supply, which in turn leads to a decrease in the output capability of the power supply itself, and the power supply is prone to overload, which may affect the stable and reliable operation of the base station equipment.

- ALC Automatic Link Control
- the downlink direction is the direction of the signal from the base station to the terminal
- the uplink direction is the direction of the signal from the terminal to the base station.
- the ALC module 110 can limit the average power of the downlink signal within the protection threshold to ensure that the digital domain power does not exceed the design range of the base station.
- the downlink signals described in the following description are all examples of IQ signals, that is, orthogonal downlink I signals and downlink Q signals.
- the working principle of the ALC module 110 is: under the control of the accumulated control signal, the average IQ of the downlink IQ signals is calculated by using the method of summing and averaging the downlink IQ signals; then, comparing the average power with the preset Protection threshold; adjust input DAC module 103 according to comparison result The IQ signal input amplitude. If the average power is greater than the protection threshold, the input IQ signal is peaked, and the input IQ signal is multiplied by a coefficient output to the DAC module 103, and the coefficient may be a ratio of a preset protection threshold to a calculated square root of the average power; If the power is less than the protection threshold, the amplitude of the IQ signal of the input DAC module 103 is kept constant.
- ALC technology is more effective for wireless power amplifier protection for continuous power transmission.
- the output power of each time slot may be different, and the peak-to-average ratio is large.
- the average power of the previous time slot cannot be used to determine the output power of the next time slot. Therefore, the ALC technology for protecting power amplifiers cannot provide timely and effective protection for GSM multi-carrier power amplifiers.
- the ALC technique does not synchronize the timing of the peaking of the downlink IQ signal with the time slot. If the signal of the input DAC module is peaked in the middle of a time slot, the amplitude of the signal in a single time slot fluctuates, which may cause error in the downlink data, thereby affecting network performance.
- the ALC technique is to cut the peak of the combined IQ signal, which will reduce the carrier power in the entire downlink channel.
- the coverage radius of the entire cell may be reduced, resulting in frequent switching of the cell phone at the cell edge, which may result in a decrease in the quality of the user's call.

- the terminal measures the power of the primary BCCH carrier of the neighboring cell and reports it to the base station controller.
- the base station controller sorts the signal strengths of the main cell BCCH carriers reported by the terminal, and serves as a basis for guiding the terminal to perform handover. If the primary BCCH carrier power of a cell decreases, the strength of the cell's primary BCCH carrier signal reported by the terminal may decrease, which may cause the terminal at the edge of the cell to perform handover frequently. An increase in the number of handovers will result in an increase in the cell drop rate, which in turn leads to a degradation in network quality.
