Abstract: An apparatus and a method for retransmission in a wireless communication terminal are provided to improve reliability and reception performance of the data transmission and reception and reduce the waste of a resource due to data retransmission by selectively retransmitting the data according to the channel state. A transmitting unit transmits the data to a reception unit by using a wireless resource allocated through the scheduling(301). After transmitting the data, the transmitting unit confirms whether the ACK signal is received from the receiving unit(303). If the NACK signal is received from the receiving unit, or the ACK or NACK signal is not received for a constant hour, the transmitting unit stores the retransmission information for data to be transmitted to the receiving unit(305). At this time, the transmitting unit does not perform the retransmission of the data. If the ACK signal is received from the receiving unit, the transmitting unit terminates the algorithm after disusing the data to be transmitted to the receiving unit.

Abstract: A method and an apparatus for reverse power control in a communication system are provided to enable a terminal to transmit reverse data by using different transmission power even if the same target PER(Packet Error Rate) is applied to HARQ(Hybrid Automatic Repeat request) traffic and non-HARQ traffic, thereby improving the reliability of a wireless link by using high transmission power for the HARQ traffic while increasing HARQ gain by applying a high target PER to the HARQ traffic. A method for reverse power control in a communication system comprises the following steps of: transmitting a power control offset, which is to be applied to traffic having a characteristic as standard, to a terminal(104)(106); and setting the transmission power of the traffic by using the power control offset in correspondence to the characteristic of the traffic which the terminal wants to transmit(110).

Abstract: A method for scheduling data traffic in a wireless communication system is provided to improve an overall throughput by controlling a MAP overhead. When data traffic of the first reference level or greater is generated, radio resources are preferentially allocated to a mobile station with a good channel state. When data traffic smaller than the first reference level is generated, radio resources are preferentially allocated to mobile stations, starting from a mobile station which has not allocated the radio resources for the longest time. When a control information amount according to allocation of data traffic exceeds the second reference level, data traffic with the same MCS(Modulation and Coding Scheme) level are collected at a single data traffic allocation region and radio resources are allocated.

Abstract: A method and an apparatus for allocating CQICHs(Channel Quality Information Channels) in a wireless communication system are provided to dynamically manage CQICH allocation and release for UEs(User Equipments) so that a base station, which communicates with a plurality of mobile stations by using finite CQICHs, can select the optimum modulation and coding scheme on the basis of exact channel quality information in transmitting data to the mobile stations. A base station selects a mobile station which occupies an arbitrary CQICH(310). A CQICH manager checks the remaining CQI report period of the mobile station(320). If the remaining CQI report period is '0', the CQICH manager determines CQICH reallocation or deallocation for the mobile station. In this case, the CQICH manager confirms whether the mobile station belongs to a gold group(330). If the mobile station belongs to the gold group, a packet generation identifier confirms whether data have been transmitted from the base station to the mobile station during allocation period of the gold group on the basis of reallocation time(331). If not, the CQICH manager reallocates a CQICH to the mobile station. But, in this case, the CQICH appoints the mobile station to a silver group(333).
