WIRELESS COMMUNICATION SYSTEM, BASE STATION, TERMINAL DEVICE, AND WIRELESS COMMUNICATION METHOD

摘要

In a communication system in which a communication is performed between a base station and one or more terminals by using one or more communication channels, a control element unit is defined by T OFDM symbols and F subcarriers. A second combination of T and F is determined for a first combination of T and F such that the number of modulation symbols (one OFDM symbol×one subcarrier) included in the control element unit defined by the second combination is closest to the number of modulation symbols included in the control element unit defined by the first combination.
