Abstract: A signal assignment unit (105) assigns a downlink control signal including resource assignment information of a PDSCH to a downlink resource. A specification unit (108) specifies a PUCCH resource using an offset value set to either a first PRB set or a second PRB set when the downlink control signal is disposed to spread over the first PRB set and the second PRB set. A signal separation unit (109) separates an ACK/NACK signal included in the specified PUCCH resource from a received signal from a terminal to which the downlink control signal has been transmitted.

Abstract: A terminal is disclosed, which is capable of appropriately determining a resource to which a DCI is mapped. A DCI receiver (203) receives first and second downlink (DL) control signals, and a signal demultiplexer (202) demultiplexes a DL data signal from a received signal, using the first and the second DL control signals. The DCI receiver (203) identifies a resource for the second DL control signal based on information on the first DL control signal, or information on the DL data signal, indicated by the first DL control signal.

Abstract: In a terminal, based on a first parameter included in each of a plurality of downlink control signals, the first parameter indicating a cumulative count of code block groups (CBGs) configuring each of a plurality of transport blocks (TBs) assigned by the plurality of downlink control signals, a HARQ-ACK generation unit generates a response signal (HARQ-ACK) for each of the code block groups. A transmission unit collectively transmits the response signals for each of the code block groups.

Abstract: Provided are wireless communication devices and methods. A wireless communication device can comprise: circuitry operative to map at least a first type of reference signals (RSs) onto orthogonal frequency division multiplexing (OFDM) symbol(s) other than the OFDM symbols onto which shortened transmission time intervals (TTIs) are mapped in a subframe, each of the shortened TTIs comprising 1-7 OFDM symbols; and a transmitter operative to transmit a physical channel in one of the shortened TTIs and transmit at least the first type of RSs.

Abstract: There are provided an apparatus, a method and a system. The apparatus comprises: a transmitter operative to transmit wireless data or signals to a second node; and a circuitry operative to determine whether one or more reserved periods are reserved between two continuous data or signals transmitted by the transmitter based on a length of configured transmission time intervals (TTIs), wherein the circuitry is further operative to: determine the one or more reserved periods are reserved between two continuous data or signals in a case that the length of configured TTI is shorter than or equal to a threshold.

Abstract: In the multiple short sequence based SRS, multiple items of sequence data having a short sequence length corresponding to a partial band are used for transmitting SRS in discontinuous bands. In the multiple short sequence based SRS, a terminal specifies a frequency domain to be used for transmitting a reference signal using predetermined sequence data, applies a phase shift index associated with the specified frequency domain to the reference signal, and transmits the reference signal to which the phase shift index is applied by using the specified frequency domain.

Abstract: A DCI receiving unit receives downlink control information (DCI) indicative of allocation of an uplink (UL) signal of a first TTI (long TTI) or an uplink signal of a second TTI (sTTI) having a shorter TTI length than the first TTI; a transmission power determination unit determines transmission power of the uplink signal of the first TTI and transmission power of the uplink signal of the second TTI; and a transmitting unit transmits the uplink signal of the first TTI and the uplink signal of the second TTI by using the determined transmission power on the basis of the downlink control information. The transmission power determination unit reserves desired transmission power for the uplink signal of the second TTI in the first TTI in a case where decoding of the downlink control information indicative of allocation of the uplink signal of the second TTI to be transmitted within the first TTI (e.g., a subframe) is completed before start of transmission of the uplink signal of the first TTI.

Abstract: Provided are an eNB, a UE and wireless communication methods. A UE according to an embodiment of the present disclosure can comprise circuitry operative to determine valid transmission time interval(s) (TTI(s)) for a physical channel in a subframe based on the resource element (RE) number of each TTI in the subframe; and a receiver operative to receive the physical channel in one or more of the valid TTI(s) by blindly decoding part or all of the valid TTI(s), wherein each TTI comprises 1-7 orthogonal frequency division multiplexing (OFDM) symbols.
