The present invention proposes a proportional fairness scheduler used in a base station, which is applicable to a high mobility environment, the scheduler comprising: a correction factor estimator which, for each user equipment in a serving cell of the base station, estimates a correction factor for an instantaneous transmission rate for a next frame according to a statistical result on changes in a channel quality in a current frame; a metric calculator which, for each user equipment in the serving cell of the base station, calculates a metric based on the instantaneous transmission rate for the user equipment, the estimated correction factor and a history throughput recorded for the user equipment; and a transmission opportunity granter which grants a transmission opportunity in the next frame to a user equipment having the optimal metric out of all the user equipments. Also, the present invention proposes a proportional fairness is scheduling method used in a base station.
