Abstract:
1. A threshold value calculation method in a threshold calculation apparatus configured to calculate a threshold value of a communication quality used when determining MCS (Modulation and Coding Scheme) corresponding to a communication quality of a radio resource in a radio base station, comprising: a step A converting, by the calculation apparatus, a first threshold value that is an ideal value into a first calculation value by using a first table indicating a correspondence relationship between a first value indicating a communication quality and a second value obtained by a calculation using a first function for the first value; and a step B of converting, by the calculation apparatus, the first calculation value into a corrected threshold value by using a second table indicating a correspondence relationship between a third value indicating a communication quality and a fourth value obtained by an arithmetic operation using a second function that is an inverse operation of the calculation using the first function in relation to the third value, wherein the corrected threshold value is used as the threshold value of the communication quality when the MCS is determined by use of the first table and the second table.
