摘要： When an H-ARQ is used for downlink high-speed packet transmission, appropriate transmit power control is performed on a retransmission packet for effective use of transmit power resources and reduced interference in a radio communication system, and the transmit power of the retransmission packets (transmission #2, transmission #3) is controlled to transmit power value so that the reception quality of the retransmission packets at the mobile station apparatus is lower than the reception quality of the initial transmission packet (transmission #1) at the mobile station apparatus. For example, the transmit power value of the retransmission packet is controlled to a value lower than the transmit power value of the initial transmission packet by a predetermined value X [dB].

摘要： Transmission destination determiner 301 selects individual communication terminal apparatus as candidates to transmit packets to and determines a transmission destination apparatus based on CQI signals from these communication terminal apparatuses. Transmission power determiner 302 monitors transmission power resources and determines the transmission power of an HS-PDSCH and the transmission power of a pilot channel. HS-PDSCH SIR estimator 303 estimates the SIR of the HS-PDSCH at the transmission destination apparatus based on the CQI signal and the transmission power. MCS determiner 304 determines the maximum TBS based on the HS-PDSCH SIR and indicates an MCS corresponding to the determined TBS to modulator 153. By this means, it is possible to maximize throughput in consideration of the transmission power of the HS-PDSCH.

摘要： Transmission destination determiner 301 selects communication terminals to be candidates to transmit a packet to from a packet transmission control signal, and determines a transmission destination apparatus based on CQI signals from the communication terminal apparatuses selected. Packet channel quality estimator estimates the quality of a received packet at the transmission destination apparatus based on the CQI signal, and, based on the estimation result, calculates a request packet quality for achieving a target packet quality upon retransmission based on the estimation result. Transmission power determiner 304, when receiving an ACK signal from the transmission destination apparatus, sets transmission power at a predetermined level, and, when receiving a NACK signal, determines transmission power to fulfill the request packet quality. By this means, the base station apparatus is able to estimate receiving quality of a packet at the communication terminal apparatus without having the communication terminal apparatus transmit packet quality information and determine transmission power required for retransmission based on the receiving quality of the packet.

摘要： A base station apparatus and communication terminal apparatus capable of estimating interference with other cells on an uplink and realizing optimum assignment. At a base station (100), a scheduling and transmission parameter determining section (113) receives soft handover information from a higher layer and does not perform individual assignment processing for a mobile station in the process of soft handover. In this way, the mobile station can perform continuous transmission at a constant transmission rate (e.g., coding rate, modulation scheme, spreading factor, transmit power, etc.).

摘要： A base station apparatus (radio transmission apparatus) transmits a radio signal of data to a mobile terminal apparatus (communication apparatus of a transmission destination). The mobile terminal apparatus receiving the radio signal determines (ST1010) information (CQI) on a downlink transmission rate enabling reception in the mobile terminal apparatus based on reception quality such as CIR to transmit to the base station apparatus. The base station apparatus extracts a CQI value from the received radio signal, while obtaining likelihood of received data (ST1020), and corrects the CQI value based on the likelihood (ST1030). Then, based on the corrected CQI value, the base station apparatus determines a downlink transmission rate (ST1040). By this means, even when the radio transmission apparatus erroneously receives the transmission rate request transmitted from the communication apparatus of the transmission destination, the communication apparatus is prevented from erroneously receiving the data transmitted from the radio transmission apparatus.

摘要： Confidence calculator 211 finds confidence based on the measurement result of the received SIR. Based on the confidence supplied from confidence calculator 211, ACK/NACK decider 212 makes a decision for the then modulated ACK signal with reference to a predetermined threshold level. For the ACK/NACK decision result, scheduler 251 instructs buffer 252 to transmit new data when an ACK signal is received, and to transmit the data of the previous transmission when a NACK signal is received. By this means, it is possible to prevent loss of the received data in the communication terminal apparatus that occurs when a NACK signal is erroneously received and the data is not retransmitted from the associated communication terminal apparatus.

摘要： The present invention relates to a method and mobile terminal for performing a data allocation process for scheduled data, non-scheduled user data and non-scheduled control data obeying restrictions on the resource utilization defined by a scheduling grant and at least one non-scheduled grant. Further, the invention relates to a method for transmitting control signaling from a network entity in a radio access network of a mobile communication system controlling the radio resources of mobile terminals to at least one of said mobile terminal and the network entity in a radio access network. In order to reduce the delays to control signaling implied by a conventional HARQ process restriction mechanism the present invention suggests a new categorization of uplink data into scheduled data, non-scheduled user data and non-scheduled control data and a new HARQ process restriction mechanism disabling certain HARQ processes for non-scheduled user data only.

摘要： The invention relates to a mobile terminal communicating resource requests for dedicated uplink channel resources in a mobile communication system. Further, the invention also relates to a method for communicating resource requests for dedicated uplink channel resources in a mobile communication system. To allow the serving cell to detect “DOWN” commands from non-serving cells during soft handover the invention suggests a new definition of criteria for setting the “happy bit” in the control information associated to data transmitted on dedicated uplink channels. According to these criteria the mobile terminal may not indicate an unhappy condition while ramping up resource utilization. Only if resources equivalent to the maximum serving grant are utilized, the transmission buffer status requires to and the power status of the terminal allows for the happy bit is set to indicate a unhappy condition.
