technical field [0001] The invention relates to the communication field, in particular to a method, device and system for adjusting power amplifier voltage and controlling time slot. Background technique [0002] Multi-carrier base stations have the advantages of high integration and high energy efficiency ratio. The application of multi-carrier technology in Global System for Mobile communications (GSM) network construction can reduce the capital expenditure (Capital Expenditure, CAPEX) of operators' network construction. ), while achieving low operating expenses (Operating Expenditure, OPEX) for network maintenance. [0003] Such as figure 1 As shown, the existing multi-carrier energy-saving technical solution is based on the static configuration parameters of the base station controller for the multi-carrier base station, the multi-carrier module calculates the possible maximum output power after power-on operation, and adjusts the drain voltage of the carrier frequency ...

AI Technical Summary

Problems solved by technology

But for GSM base stations, the channel modulation method, channel power and channel occupancy of each carrier are constantly changing. If the power amplifier voltage is no longer dynamically adjusted after the base station is powered on, when the downlink power control of the base station takes effect, the power amplifier The efficiency of the power amplifier at low power output will drop significantly compared to the efficiency of high power output, resulting in a decline in the energy efficiency of the GSM network

[0004] At the same time, when the existing energy-saving technical solutions are applied to the multi-carrier module, dynamically turning off the power amplifier voltage of the idle time slot of the multi-carrier module will lead to the deterioration of the radio frequency emission index of the multi-carrier module, and the reduction of the static power consumption of the power amplifier cannot be achieved.
