A communication apparatus comprises a first communication unit configured to connect to another communication apparatus and communicate by using a PCR (Primary Connectivity Radio) function, and a second communication unit configured to communicate with the other communication apparatus by using a WUR (Wake Up Radio) function. The communication apparatus stores, in a storage unit, a first transmission rate which is a transmission rate of the first communication unit used before the WUR mode is started, and sets the stored first transmission rate as a second transmission rate which is a transmission rate of the first communication unit used when the WUR mode has been ended.
