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： An OFDM mobile communication system includes a system controller for dividing an OFDM symbol into a control channel and a data channel, multiplexing the control channel to control subchannels, and allocating the multiplexed control subchannels to base stations. The base stations simultaneously transmit control signals on the control allocated subchannels and data on the data channel. Mobile nodes receive an OFDM symbols with the multiplexed control channels for them and a data channel for selecting a base station according to information in the control subchannels. The mobile node simultaneously processes control subchannels received from two base stations using one physical layer module.

摘要： Disclosed is a symbol synchronization method in an OFDM-based communication system which includes multiple access nodes supporting wireless connection of terminals, supports multi-connection of each terminal for the access nodes and performs synchronization by means of a cyclic prefix. The symbol synchronization method includes monitoring connection of a new access node; setting a number of times by which the new access node transmits equal symbols and a number of times by which at least one existing access node transmits the equal symbols when the connection of the new access node is detected; transmitting the equal symbols by the determined number of times by each access node; and performing synchronization by means of the symbols received from the access nodes by the terminal.

摘要： An apparatus and method for adaptively allocating subchannels according to frequency reuse rates in an OFDMA system are provided. To allocate one or more subchannels to one or more MSs, information related to an optimum FRF and a modulation scheme is received from the plurality of MSs, the number of subchannels required for each FRF is calculated according to the received information, subchannels are allocated to the BS for each FRF, based on the calculated subchannel numbers from the BS and neighboring BSs, and the allocated subchannels are allocated to the MSs.
