System und Verfahren zur gerechten proportionalen Verteilung

摘要

A system and a method for proportionally fairscheduling is provided for efficiently exchanging information between a base station and a mobile station in a wireless communication system. The system includes a base station performing proportionally fair (PF) scheduling for data transmission by receiving channel quality information (CQI) fedback-transmitted from plural mobile stations connected to the base station.-, The base station determines a number of first mobile stations feeding back CQI required by the base station, calculates an actual number of second mobile stations, which have fed back CQI using the CQI received from the plural mobile stations, controls a first scheduling metric value by comparing the number of the first mobile stations with the number of the second mobile stations, and transmits the controlled first scheduling metric value to the plural mobile stations, the first scheduling metric value corresponding to information used for determining if the plural mobile stations feedback-transmit the CQI, and the plural mobile stations determine if the mobile stations feedback-transmit the CQI by comparing the first scheduling metric value received from the base station with second scheduling metric values of the plural mobile stations.
