1. A communication apparatus, comprising:
at least one memory and at least one processor, which function as:
a communication control unit configured to enable both a first mode in which wireless communication is performed via an external access point, wherein the external access point is located outside the communication apparatus, and a second mode in which wireless communication is not performed via the external access point;
a reception unit configured to receive a first trigger frame including information about execution of carrier sensing, from the external access point while the first and second modes are enabled, the first trigger frame complying with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard;
a transmission unit configured to transmit, in a case where the first trigger frame includes information indicating execution of carrier sensing, data after executing carrier sensing; and
a communication unit configured to communicate, in a case where the communication apparatus operates as a master station configured to determine a communication channel used in wireless communication of the second mode while the first mode and the second mode are enabled, with a slave station apparatus connected to the master station,
wherein the communication unit does not transmit, in a case where the communication apparatus operates as the master station while the first mode and the second mode are enabled and the first trigger frame is received, information indicating execution of carrier sensing.
