摘要： A transport control method in a transmitter of a wireless communication system, which includes a transport layer having a congestion control function of transmitting data in a segment basis and retransmitting a segment if an RTO timer expires before receipt of an ACK segment is received in response to transmission of the segment and a MAC layer for detecting receipt of an ACK segment through a wireless link and transporting the detected ACK segment to the transport layer, includes temporarily storing received ACK segments in the MAC layer; detecting an average transmission rate of data segments; and transporting the stored ACK segments to the transport layer at the average transmission rate. Accordingly, by controlling an upward transport rate of a received ACK message by referring to an RTO value of a TCP in a MAC layer, unnecessary retransmission can be prevented by a congestion control function.

摘要： An apparatus and method for allocating a channel using an auction algorithm in a wireless communication system. The method includes measuring a data rate of each channel; selecting one of the channels, when information on the channels is received from a base station, using the received information on the channels and the measured data rate; and determining a bidding price of the selected channel. Performance of the entire system can be improved by reducing complexity as well as guaranteeing an optimal value in the channel allocation.

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.
