A communication apparatus that performs communication compliant with IEEE 802.11 standard series performs communication with another communication apparatus using a first channel access method that uses at least a Primary channel of one link and a second channel access method that, in a case where the Primary channel is in a busy state, uses a Non-Primary channel different from the Primary channel, and does not use the Primary channel, in a time period in which communication is being executed with a first communication apparatus using the second channel access method, in a case where the Primary channel becomes available for use, executing a first control, a second control, a third control, or fourth control.
