Patent ID: 10492098

Abstract:
A transmitting terminal (1A) transmits first D2D control information (522, 523) in one or more subframes within a first subframe pool (511) within a first D2D control period (501) and performs data transmission (531-534) in accordance with the first D2D control information (522, 523) in one or more subframes within a second subframe pool (512) within the first D2D control period (501). The first D2D control information (522, 523) contains a second information element indicating whether the first D2D control information (522, 523) is valid in at least one D2D control period (502, 503) occurring after the first D2D control period (501). This makes it possible to contribute, for example, to reducing failure in reception of scheduling assignment information that is transmitted in a radio resource region for control in a periodic D2D control period and that specifies D2D transmission resources.
