    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.

    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 separating data units from a received concatenated burst in a wireless communication system, and an apparatus and method for generating a concatenated data unit during transmission. If a reception end receives the burst, it determines if each data of the burst is a header of the data unit, such that it can separate the data unit from the burst. A transmission end designates individual starting points of data units to be equal to an integer multiple position of a predetermined size, and constructs a concatenated format of the data units, such that it generates the burst.
