摘要： A wireless communications system includes: a first communications processing section for implementing a dedicated communications function that is only for the first wireless communications scheme; a second communications processing section for implementing a dedicated communications function that is only for the second wireless communications scheme; a shared transceiver section shared by the first communications processing section and the second communications processing section; a scheme selection section for selectively inputting a signal from the first communications processing section or a signal from the second communications processing section to the shared transceiver section; and a communications switching control section for indicating, to the scheme selection section, a scheme to be selected. The communications switching control section determines a switching timing based on frame and sub-frame information from the first communications processing section in an operation of switching from the first wireless communications scheme to the second wireless communications scheme or an operation of searching for a communications target station using the second wireless communications scheme.
