摘要： A method and device for frequency deviation pre-correction are provided. The method includes: estimating an uplink frequency deviation value of a terminal, and obtaining a historic value of the uplink frequency deviation pre-correction that has been used for the frequency deviation pre-correction of the terminal; according to the historic value of the uplink frequency deviation pre-correction, determining a current value of the uplink frequency deviation pre-correction of the terminal, the current value of the uplink frequency deviation pre-correction being closer to the uplink frequency deviation value than the historic value of the uplink frequency deviation pre-correction; by using the current value of the uplink frequency deviation pre-correction, pre-correcting the frequency deviation of the terminal, thereby the signal detection performance of the terminal can be effectively improved.
