The present disclosure provides a method for forming an uplink burst pulse in a communication system, including: a code channel weighting coefficient for each uplink code channel is configured, wherein the code channel weighting coefficient contains a weighting coefficient of at least one modulation mode; a data modulation symbol on each uplink code channel is weighted with the weighting coefficient corresponding to its modulation mode, to obtain a weighted data modulation symbol on each uplink code channel; the weighted data modulation symbol on each uplink code channel is accumulated, and a total uplink transmission power for an accumulation value of the weighted data modulation symbol is configured after performing pre-transmission processing for the accumulation value. Accordingly, the present disclosure provides an apparatus for forming an uplink burst pulse in a communication system, which includes a weighted data modulation symbol obtaining unit, a weighted data modulation symbol accumulation unit, a pre-transmission processing unit and a total uplink transmission power configuration unit. The present disclosure enables the forming of the uplink burst pulse supporting the high-order modulation with high peak-to-average ratio at a low cost.
