The invention provides a PDCH configuring method and device. The method comprises the steps that a single slot time theoretical rate of a cell is calculated according to the single channel rate of the cell and a high encoding proportion corresponding to the single channel rate; the quantitative evaluation is carried out on the data service perception degree of a terminal user of the cell to obtain a quantitative evaluation parameter; the single time slot demand rate of the cell is determined according to the first corresponding relation among the pre-counted cell service volume value, the time delay and the single user single time slot rate and the quantitative evaluation parameter; the theoretical channel value of the cell is calculated according the multi-time-slot capability parameters of terminals in the cell and the terminal concurrence number within the preset time; the demand channel value of the cell is worked out according to the single time slot theoretical rate, the single time slot demand rate and the theoretical channel value of the cell; the cell channel configuration is carried out according to the current channel value and the demand channel value of the cell. According to the PDCH configuring method and device, a PDCH configuration scheme is formulated according to the actual cell situation, and the user perception is presented.
