Title: TERMINAL, BASE STATION AND METHODS THEREFOR
Abstract:
A reception terminal (1B) receives D2D control information (522, 523) transmitted from a transmission terminal (1A) over a physical control channel (511) during a D2D control period (501). The D2D control information (522, 523) indicates that one or more radio resources during the D2D control period (501) are designated as scheduled radio resources (533-534) via which a physical data channel is possibly to be transmitted. If the transmission of the physical data channel from the transmission terminal (1A) via these scheduled radio resources (533-534) is not detected in the physical layer of the reception terminal (1B), the MAC layer of the reception terminal (1B) transmits no negative feedback to the transmission terminal (1A). This can contribute, for example, to suppression of transmission of unnecessary negative feedbacks from the reception terminal to the transmission terminal in D2D transmissions.
