1. A communication apparatus comprising:
one or more processors; and
one or more memories including instructions that, when executed by the one or more processors, cause the communication apparatus to operate as:
an establishing unit configured to establish a plurality of links including a first link and a second link different in frequency channel to another communication apparatus;
a first backoff unit configured to perform backoff processing on the first link on a basis of a first parameter set or a second parameter set;
a first communication control unit configured to control communication with the another communication apparatus on the first link;
a second backoff unit configured to perform the backoff processing on the second link on a basis of the first parameter set or the second parameter set; and
a second communication control unit configured to control communication with the another communication apparatus on the second link, wherein
the first communication control unit and the second communication control unit are capable of performing control such that the first backoff unit performs the backoff processing on a basis of a random backoff time that is based on the first parameter set, and such that frame transmission using the first link and the second link is performed on a basis of a confirmation that a wireless medium related to the first link is idle,
when the frame transmission using the first link and the second link is performed, the first backoff unit and the second backoff unit perform the backoff processing on a basis of a random backoff time that is based on the second parameter set, and
an expectation value of the random backoff time that is based on the first parameter set is less than an expectation value of the random backoff time that is based on the second parameter set.
