摘要： A method of scheduling uplink resources in a wireless communication system supporting VoIP service is provided. A BS allocates an identical amount of the resource continuously until an uplink data rate is changed by an SS's request for a data rate change. When the data rate is changed, the SS reports this event to the BS so that the BS allocates an amount of resource corresponding to the requested data rate.

摘要： A resource allocation method in a wireless communication system for providing a communication service in a given system frequency band to access terminals (ATs) within a broad-band service area around an access point (AP) and to ATs within a narrow-band service area having a radius larger than the radius of the broad-band service area. In the resource allocation method, the system frequency band is divided into a Time Division Duplexing (TDD) interval and a Frequency Division Duplexing (FDD) interval in time, and the TDD interval and the FDD interval are defined as TDD resources and FDD resources, respectively. The TDD resources are allocated to an AT within the broad-band service area, and the FDD resources are allocated to an AT within the narrow-band service area.

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.

The system supports time and frequency division duplexing modes and includes a base station having a cellular communication range based on a cellular mode and mobile stations within the cellular communication range. The base station divides each available frequency resource into frames for communication, and each frame switches between a real-time service mode and a non-real-time service mode at a switching time within the frame. Communication is performed with the mobile stations within the cellular communication range via at least one of an uplink and a downlink in the real-time service mode of each frame according to the frequency division duplexing mode. Communication is performed with the mobile stations via the uplink and the downlink in the non-real-time service mode of each frame according to an ad hoc mode based on the time division duplexing mode.
