Abstract:
1. A transmission control frame generating apparatus comprising: a calculating section that calculates a reference channel state level between a plurality of subcarriers from a plurality of subcarrier channel state levels respectively corresponding to the plurality of subcarriers; a setting section that sets, based on a subcarrier channel state level corresponding to any of the plurality of subcarriers and the reference channel state level, a group channel state level of a group including said any of the plurality of subcarriers; and a generating section that generates a frame that is used in control of transmission with said any of the plurality of subcarriers and indicates a first value expressing the calculated reference channel state level and a second value expressing the set group channel state level, wherein: the setting section sets a group size of the group and the group channel state level of the group, makes the group size of the group larger when a relative size of the group channel state level of the group is larger with respect to the reference channel state level, and makes the group size of the group smaller when the relative size of the group channel state level is smaller.
