In a wireless communication system which can share the same frequency band with time division duplexing (TDD) and frequency division duplexing (FDD), a wireless terminal carries out an FDD downlink reception in a second frequency band overlapping a first frequency band allocated to TDD, thus carrying out reception at the TDD downlink reception timing. Alternatively, a wireless terminal carries out a TDD downlink reception in a second frequency band overlapping a first frequency band allocated to FDD, thus carrying out reception at the FDD downlink reception timing.
