BASE STATION APPARATUS, COMMUNICATION TERMINAL, AND RESOURCE ALLOCATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a base station apparatus, a communication terminal, and a resource allocation method capable of determining a modulation system and a coding rate by selecting an optimum MCS level. SOLUTION: An ACK/NACK information detection section 106 detects ACK information or NACK information denoting an error detection processing result in communication terminals. A channel quality information detection section 107 detects channel quality information denoting an MCS level requested from the communication terminals. A decoding repetition detection section 108 detects repetition information denoting the number of repetitive times of error correction decoding processing carried out by the communication terminals. A scheduling section 151 allocates a communication terminal being a data transmission destination on the basis of the channel quality information and determines a modulation system and a coding rate of transmission data to be transmitted to the allocated communication terminal on the basis of the ACK/NACK information, the channel quality information, and the repetitive number information.
