Abstract: Transmitter (101) extracts CQI values representative of reception qualities measured by and transmitted from receivers (102-1 through 102-?) as representing reception states of antennas (121-1 through 121-?) of receivers (102-1 through 102-?), from data receivers (102-1 through 102-?) and received by transmitter (101), combines the extracted CQI values depending on preset weighting coefficients, calculates resource coefficients for assigning resources for transmitting data to receivers (102-1 through 102-?) from the combined CQI values, and assigns resources for transmitting data to receivers (102-1 through 102-?) based on the calculated resource coefficients.

Abstract: Transmitter extracts CQI values representative of reception qualities measured by and transmitted from receivers as representing reception states of antennas of receivers, from data receivers and received by transmitter, combines the extracted CQI values depending on preset weighting coefficients, calculates resource coefficients for assigning resources for transmitting data to receivers from the combined CQI values, and assigns resources for transmitting data to receivers based on the calculated resource coefficients.

Abstract: In a TBS (Transport Block Size) determination apparatus, a CQI (Channel Quality Indicator) value setting section sets a CQI value which is transmitted from a UE (User Equipment) which communicates based on a packet transmission standard HSDPA (High Speed Downlink Packet Access). A TBS acquiring section acquires a TBS by referring to a CQI mapping table based on the set CQI value. A BLER (BLock Error Rate) setting section sets a BLER before, simultaneously, or after the setting a CQI value, and before, simultaneously, or after the acquiring a TBS. A TBS changing section changes the TBS based on the BLER.

Abstract: The invention is applied to a radio base station apparatus that allocates a resource to HS-PDSCH and transmits data via the HS-PDSCH to a mobile station. The radio base station apparatus includes: a BLER measurement unit that measures the BLER of a signal received from the mobile station; and a resource allocation unit that, when the measured BLER is equal to or larger than a target value, increases stepwise by a given amount, the amount of data transmit power allocated as the resource to the HS-PDSCH.

Abstract: A radio apparatus is disclosed for improving the throughput of data transfer using a HARQ-based automatic retransmission. The radio apparatus performs a HARQ-based automatic retransmission. In this event, a redundancy version control unit identifies a redundancy version in the retransmission based on a redundancy version in the preceding transmission in which the need for retransmission arose. A HARQ processing unit performs rate matching on each of the systematic bits and parity bits of data to be retransmitted in accordance with the redundancy version identified by the redundancy version control unit.

Abstract: A radio base station device detects congestion on transmission lines between the radio base station and a radio base station controller shared by a plurality of radio communication terminals based on the results of error detection that is carried out for each of the plurality of radio communication terminals and reduces the data rate of radio communication terminals that are selected without regard to which radio communication terminals was the cause of congestion detection.
