Abstract: a terminal () includes an initiator functional unit () for acquiring information to be used for estimating position information of the terminal by performing frame exchange with a neighboring responder terminal, a responder functional unit () for providing the information to be used for estimating the position information of the initiator terminal by performing the frame exchange with a neighboring initiator terminal, and a control unit () for controlling the initiator functional unit () and the responder functional unit (). the control unit () estimates the position information of the terminal () based on the information acquired by controlling the terminal () to function as the initiator terminal using the initiator functional unit () and by controlling the terminal () to exchange frames with the neighboring responder terminal, and then controls the terminal () to function as the responder terminal using the responder functional unit () and the position information.

Abstract: a system is disclosed in which a base station defines a search space, in which a communication device can search for control information. the search space is characterised by at least first information which is related to a starting subframes of a plurality of portions of the search space and second information which is related to a periodicity between respective starting subframes, each portion representing a different candidate for the transmission of control information. the base station obtains a parameter indicating both the initial starting subframe and the periodicity and transmits the generated parameter to the communication device.
