Method and apparatus for deciding channel quality indicator in wireless communication system
First Claim
1. A method of deciding a Channel Quality Indicator (CQI) using a genetic algorithm (GA) in a mobile communication terminal, comprising:
- randomly generating CQI values encoded into genotypes to form an initial genetic group;
evaluating fitnesses using the CQI values and a measured block error rate (BLER), and if the CQI value indicating the highest fitness is not within a range of the BLER, selecting a specific gene of genes of the initial genetic group to perform crossover and mutation operations; and
repeating the crossover and mutation operations to allow a new genetic group generated by the crossover and mutation operations to be within the range of the BLER.

Abstract
Provided are a method and an apparatus for deciding a channel quality indicator (CQI) in a wireless communication system. The method includes randomly generating CQI values encoded into genotypes to form an initial genetic group; evaluating fitnesses using the CQI values and a measured block error rate (BLER), and if the CQI value indicating the highest fitness is not within a range of the BLER, selecting a specific gene of genes of the initial genetic group to perform crossover and mutation operations; and repeating the crossover and mutation operations to allow a new genetic group generated by the crossover and mutation operations to be within the range of the BLER.

10. An apparatus for deciding a Channel Quality Indicator (CQI) using a genetic algorithm (GA) in a mobile communication terminal, comprising:
a CQI selector for randomly generating CQI values encoded into genotypes to form an initial genetic group measuring fitnesses using the CQI values and a measured block error rate (BLER) if the CQI value indicating the highest fitness is not within a range of the measured BLER, selecting a specific gene of genes of the initial genetic group to perform crossover and mutation operations, and repeating the crossover and mutation operations to allow a new genetic group generated by the crossover and mutation operations to be within the range of the measured BLER so as to search for the CQI values. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A non-transitory computer-readable recording medium having recorded thereon a program for a Channel Quality Indicator (CQI) using a genetic algorithm (GA) in a mobile communication terminal, comprising:
-
a first code segment, for generating CQI values encoded into genotypes to form an initial genetic group; and a second code segment, for evaluating fitnesses using the CQI values and a measured block error rate (BLER), and if the CQI value indicating the highest fitness is not within a range of the BLER, selecting a specific gene of genes of the initial genetic group to perform crossover and mutation operations; and a third code segment, for repeating the crossover and mutation operations to allow a new genetic group generated by the crossover and mutation operations to be within the range of the BLER.
