Abstract: PURPOSE: An apparatus and a method for uplink scheduling in a broadband wireless communication system are provided to prevent the occurrence of an uplink burst error by enabling the transmission power of a terminal to be proximate to the maximum transmission power. CONSTITUTION: A calculation unit(118) predicts the entire transmission power of a terminal. If the entire transmission power is equal to or larger than a reference value, a margin determiner(110) adjusts transmission power margin for a setup period to be larger than a default value. A wireless resource determination unit(114) determines the number of slots allocated to the terminal by using the determined transmission power margin. A management unit(116) updates a parameter based on the uplink transmission power information by checking whether or not an error exists in an uplink burst.

Abstract: PURPOSE: A device and a method for adjusting offset in a wireless communication system are provided to adjust timing offset and frequency offset of a terminal by using non demand ranging response message. CONSTITUTION: An offset producing unit(321) calculates an offset average value of a terminal by using frequency offset and timing offset of previously presumed terminal if a uplink data provided from a terminal dose one exists. A control unit(320) determines whether to transmits a non demand ranging response message by using the offset average value of the terminal. The transmission device(330) transmits the non demand ranging response message including the offset adjusting value of the terminal.

Abstract: PURPOSE: A DL link HARQ channel allocation method in a wireless communication system is provided to operates private HARQ of a VoIP SF(Service Flow) by operating a HARQ channel mapping method inside a scheduler. CONSTITUTION: A BS(Base Station) scheduler sets a VoIP_State on if the traffic is VoIP queue(300,302). The base station scheduler sets a specific HARQ(Hybrid Automatic Repeat request) channel as a VoIP private HARQ channel(304). If the term when the traffic is not in the VoIP queue is not over a VoIP_State_Threshold frame, the base station scheduler sets the VoIP_State off(306,308). The base scheduler releases the VoIP private HARQ(310).
Abstract translation: 目的：提供无线通信系统中的DL链路HARQ信道分配方法，以通过在调度器内部操作HARQ信道映射方法来操作VoIP SF（业务流）的专用HARQ。 规定：如果流量是VoIP队列（300,302），BS（基站）调度器将设置VoIP_State。 基站调度器将特定HARQ（混合自动重传请求）信道设置为VoIP专用HARQ信道（304）。 如果流量不在VoIP队列中的术语不超过VoIP_State_Threshold帧，则基站调度器将关闭VoIP_State（306,308）。 基本调度器释放VoIP专用HARQ（310）。

Abstract: An offset compensation method and a system thereof for compensating timing offset and frequency offset without transmitting a ranging code in a wireless communications system are provided to compensate timing offset and frequency offset by using a non-demand ranging response message. An IIR(Infinite Impulse Response) filter(406) computes one or more offset among average timing offset to a current frame and an average frequency offset. A reference value comparator(408) compares value and standard value of one or more offset of being computed in the IIR filter. A message generator(410) produces the non-demand ranging response message in which the correction value of one or more offset is included to correspond to the comparison result of the standard value comparator.
