WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION METHOD, AND BASE STATION
A wireless communication system includes: a first wireless terminal capable of communicating through both a first communication scheme using a first frequency band and a second communication scheme using a second frequency band higher than the first frequency band; a second wireless terminal that is compatible with communication through the first communication scheme and is not compatible with communication through the second communication scheme; and a base station that is compatible with multi-link and accommodating the first wireless terminal and the second wireless terminal. A carrier sense level during transmission in communication between a base station and the first wireless terminal through the first communication scheme is set to a value less than a predetermined value that is a carrier sense level during transmission in communication between the base station and the second wireless terminal through the first communication scheme.
