摘要： A UE/queue selected by a scheduler is input to an offset table (111) and a corresponding offset value is output to a CQI conversion section (112). Using this offset value, the CQI conversion section (112) converts a CQI output from a demodulation/decoding section and outputs the converted CQI to an adaptive modulation parameter determination section (113). Based on the converted CQI, the adaptive modulation parameter determination section (113) determines and outputs adaptive modulation parameters with reference to an adaptive modulation parameter table (114). Then, a transmission packet is adaptively modulated using these adaptive modulation parameters. This makes it possible to realize fast data transmission while satisfying QoS of the transmission packet.

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.
摘要翻译：本发明涉及一种方法和移动终端，用于对调度数据执行数据分配处理，非调度用户数据和非调度控制数据遵循由调度授权定义的资源利用的限制，以及至少一个非调度授权。此外，本发明涉及一种用于从移动通信系统的无线电接入网络中的网络实体发送控制信令的方法，所述移动通信系统将无线电接入网络中的至少一个所述移动终端和所述网络实体控制移动终端的无线电资源。为了减少控制由常规HARQ过程限制机制所暗示的信令的延迟，本发明建议将上行链路数据新分类为调度数据，非调度用户数据和非调度控制数据以及新的HARQ过程限制机制禁用某些仅针对非调度用户数据的HARQ进程。

摘要： A transmission method selection section (223) selects either a first packet transmission method or a second packet transmission method. When the first packet transmission method is selected, an SRQ information generation section (224) generates SRQ (scheduling request) information based on the amount of data calculated by a data amount measuring section (221) and/or the retention time thereof, and the transmission power that can be used for packet data transmission calculated by a transmission power calculation section (222). On the other hand, when the second packet transmission method is selected, the SRQ information generation section (224) does not perform SRQ information generation, or generates SRQ information of a specific value for which packet data transmission is never permitted. By this means, in a radio communication system in which packet transmission is performed on uplinks and the packet transmission method is switched adaptively, the packet transmission method can be reported without transmitting a dedicated signal to a base station apparatus.
摘要翻译：发送方法选择部（223）选择第一分组发送方法或第二分组发送方法。当选择第一分组发送方法时，SRQ信息生成部（224）基于由数据量计测部（221）计算出的数据量和/或其保留时间生成SRQ（调度请求）信息，可以用于由发送功率计算部（222）计算的分组数据发送的发送功率。另一方面，当选择第二分组发送方法时，SRQ信息生成部（224）不执行SRQ信息生成，或者生成不允许分组数据发送的特定值的SRQ信息。通过这种方式，在上行链路进行分组发送并且分组发送方式自适应地进行切换的无线通信系统中，可以报告分组发送方法，而不向基站装置发送专用信号。

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 communication terminal apparatus that can perform an appropriate system operation at the network side and also can avoid a reduction in throughput and a reduction in system efficiency. In this apparatus, a compressed mode calculating part (124) determines, based on compressed information and slot format information, a slot that is a gap in a frame of a compressed mode. A transmission power control part (125) establishes a transmission power obtained by increasing, by &Dgr; Pilot, the transmission power as designated and set by a TPC command for the slots other than the gap in the frame of the compressed mode. A DPCCH transmission power reporting part (127) outputs, to a channel encoding part (128), a report value indicative of the transmission power obtained by removing the effect of &Dgr; Pilot from the transmission power established by the transmission power control part (125).

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.
