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: A UE includes an EUTRA-CMR reception unit that receives a codec mode request (EUTRA-CMR) including a codec mode that is determined by an eNB in accordance with a radio condition of the UE, a mode switching notification unit that notifies an encoder of switching to the codec mode included in the received codec mode request; and a mode switching acknowledgement unit that transmits a response message to the eNB when confirming that the encoder switches the codec mode.

Abstract: A base station (100, 300) is provided with a transmitter and a receiver. The transmitter (109) transmits a downlink signal in a downlink transmission region, in a time unit that includes the downlink transmission region, an uplink transmission region, and a gap period that is a switching point between the downlink transmission region and the uplink transmission region. The receiver (111) receives an uplink signal in the uplink transmission region, in the time unit. Furthermore, a delay tolerant signal for which a delay is tolerated more than for the downlink signal and the uplink signal is mapped to within the gap period.

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.

Abstract: A resource assignment determiner determines a resource for a PDSCH intended for an MTC terminal, and a transmitter transmits an MPDCCH that includes resource assignment bits indicating the resource thus determined and transmits the PDSCH using the resource thus determined. The MPDCCH is a PDCCH intended for the MTC terminal. The resource assignment bits are associated with a resource that is used when the MPDCCH and the PDSCH are transmitted in the same subframe and a resource that is used when the MPDCCH and the PDSCH are transmitted in different subframes.

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 repeater generates repetition signals by repeating an uplink signal over a plurality of subframes. If the plurality of subframes do not include a transmission candidate subframe of a sounding reference signal used to measure uplink reception quality, a controller sets a first transmission format to all the plurality of subframes, and if the plurality of subframes include the transmission candidate subframe, the controller sets a second transmission format to all the plurality of subframes. A transmitter transmits the repetition signals using the set transmission format.
