Abstract: A user equipment (UE) receives a physical uplink shared channel (PUSCH) config information element (IE) in form of radio resource control (RRC) signaling; configures a table which is defined by a PUSCH time domain resource allocation list IE carried in the received PUSCH config IE, the table comprising rows, each with a value indicating a PUSCH mapping type, a value K2 indicating a slot offsets, and a value SLIV indicating a start and length indicator value; and receives downlink control information (DCI) in form of medium access control (MAC) signaling carrying a time-domain resource assignment filed with value m, wherein the value m provides a row index m+1 to the RRC configured table. The UE determines allocated resources for an initial PUSCH transmission and allocated resources for at least one repetition thereof, and performs a PUSCH transmission using the respectively determined allocated resources.

Abstract: An integrated circuit includes control circuitry and transmitting circuitry. The control circuitry maps data or a reference signal onto resources including orthogonal subcarriers of a first numerology and a second numerology, which differ at least by subcarrier spacing and are frequency-multiplexed on a subcarrier basis. The control circuitry assigns no transmit power to at least one subcarrier located between a subcarrier of the first numerology and a subcarrier of the second numerology. The subcarriers of the second numerology include: inter-numerology-orthogonal subcarriers, each of which is centrally aligned with a subcarrier of the first numerology, and non-inter-numerology-orthogonal subcarriers not centrally aligned with any subcarrier of the first numerology and located between two adjacent subcarriers of the first numerology. The control circuitry assigns no transmit power to at least one of the non-inter-numerology-orthogonal subcarriers. The transmitting circuitry transmits the mapped data or reference signal.

Abstract: The present disclosure relates to a user equipment (UE) which comprises a transmitter, which transmits a signal to a base station over a channel, wherein the signal is transmitted based on an initial channel quality information indicating a first channel quality of the channel. A receiver of the UE receives a transmission quality information indicating a second channel quality of the channel used for transmitting the signal. A processing circuitry of the UE estimates a transmission quality based on the initial channel quality information and the transmission quality information, wherein the transmission quality indicates whether the transmission of the signal over the channel was successful or not.

Abstract: Provided is a terminal that can appropriately transmit an uplink signal. In a terminal (200), a control unit (211) determines a processing mode with respect to uplink data and uplink control information according to a requirement for at least one of uplink data and uplink control information when transmission of an uplink data channel that includes the uplink data and transmission of an uplink control channel that includes the uplink control information temporally overlap. A transmission unit (218) transmits the at least one of the uplink data and the uplink control information on the basis of the determined processing mode.

Abstract: According to the present invention, a base station can dynamically change a repetition transmission method as appropriate. In a base station (100), a repetition control unit (103) determines a data repetition pattern for a terminal (200). A transmission unit (109) repeatedly transmits data (repetition transmission) on the basis of the repetition pattern. The data repetition pattern corresponds to control information to be reported to the terminal (200) by dynamic signaling.
