1. A wireless communication device comprising:
a control circuit that transmits a first parameter and a second parameter, the first parameter being used for setting of communication in which a wireless communication terminal uses a plurality of links, the second parameter being used for setting of communication in which the wireless communication terminal uses a single link,
wherein the first parameter and the second parameter each include a parameter related to acquisition of a transmission opportunity,
wherein the first parameter and the second parameter each include, as the parameter related to the acquisition of the transmission opportunity, a parameter related to a frame transmission interval or a parameter related to transmission waiting time, and the frame transmission interval and the transmission waiting time are set to be smaller in the first parameter than in the second parameter, or
wherein the first parameter and the second parameter each include, as the parameter related to the acquisition of the transmission opportunity, a value related to occupation time of a channel, and the value related to the occupation time of the channel is set to be longer in the first parameter than in the second parameter.
