Abstract: According to the present invention, transmission is efficiently and repeatedly performed within a slot. The number of repetitions in the slot is calculated using OFDM symbol allocation in a slot notified using a predetermined field during RRC signaling or DCI formatting and the number of divisions in the slot notified by the RRC signaling (or the number of OFDM symbols serving as repetition unit). When the calculated number of repetitions does not satisfy a predetermined condition, repeated transmission is not performed.

Abstract: The present disclosure includes a control unit that performs an uplink (UL) data transmission setting according to a radio resource control (RRC) message and a transmitting unit that transmits UL data according to the UL data transmission setting. The RRC message includes setting information of a plurality of configured UL grants (CGs). The setting information includes at least first and second CGs for each of at least one bandwidth part (BWP). The setting information further includes setting information related to transmission intervals for the first and second CGs. The control unit sets at least the first and second CGs for each BWP according to the setting information. The transmitting unit, when at least a part of the transmission interval of the first and second CGs overlap each other, interrupts UL data transmission of the first CG to perform UL data transmission of the second CG.

Abstract: The present invention is to improve the user experience with respect to the fact that, in a case that a viewer watches with a large screen ultra high density display apparatus, most of field of view is covered by the video, and consciousness is focused on the center of the field of view, so the recognition capability for each video information in displaying multiple pieces of video information is reduced. Recognition of multiple pieces of video information is enhanced, by providing multiple pieces of video information and acoustic information according to a display apparatus used by a viewer from a network side device, and reproducing the acoustic information using an audio object along with display of the multiple pieces of video information on the display apparatus side.
