Abstract: Provided are a terminal device and a retransmission control method that make it possible to minimize increases in overhead in an uplink control channel (PUCCH), even if channel selection is used as the method to transmit response signals during carrier-aggregation communication using a plurality of downlink unit bands. On the basis of the generation status of uplink data and error-detection results obtained by a CRC unit, a control unit in the provided terminal uses response signal transmission rules to control the transmission of response signals or uplink control signals that indicate the generation of uplink data. If an uplink control signal and a response signal are generated simultaneously within the same transmission time unit, the control unit changes the resources allocated to the response signal and/or the phase point of the response signal in accordance with the number and position of ACKs within the error-detection result pattern.

Abstract: In the base station (100), a search space setting unit (103) sets a search space on the basis of a search space setting rule in accordance with R-PDCCH range of a setting target slot, and an allocating unit (108) places DCI in one of a plurality of candidates of to-be-decoded unit range included in the set search space. The search space setting rules are associated with respective numbers of candidates of to-be-decoded unit range corresponding to the respective ones of a plurality of numbers of connections for R-CCE, and a first search space setting rule of a slot 0 and a second search space setting rule of a slot 1 are different from each other in terms of the patterns related to the numbers of candidates of to-be-decoded unit range corresponding to the plurality of numbers of connections for R-CCE.

Abstract: The present disclosure relates to receiving and transmitting data in a frame with subframes of a wireless communication system, each subframe being either an uplink subframe accommodating uplink signal, a downlink subframe accommodating downlink signal or a special subframe including a downlink signal portion as well as an uplink signal portion. A control signal includes a special subframe configuration specifying the length of the uplink and/or downlink portion of the special subframe. The mapping and demapping of user data and/or control data including feedback information in a transmission time interval, TTI, onto or from one subframe is then performed, wherein the length of a second TTI for mapping onto the uplink portion of a special subframe is shorter than a first TTI for mapping onto an uplink subframe, or a first number of TTIs mapped onto the uplink subframe is larger than a second number of TTIs for mapping onto the uplink portion of a special subframe. The data are received or transmitted accordingly.

Abstract: Provided is a user equipment (UE), a scheduling node, and communication methods for UE and, respectively, scheduling node. The UE comprises a transceiver which, in operation, receives a configuration of a PoSS (power saving signal) time window for monitoring a PoSS and preceding a DRX (discontinuous reception) ON period for monitoring a PDCCH (physical downlink control channel), wherein the PoSS indicates whether or not the UE starts monitoring for the PDCCH in the DRX ON period and circuitry which, in operation, determines, based on the configuration, the PoSS time window, and controls the transceiver to perform monitoring for the PoSS within the PoSS time window.

Abstract: A communication apparatus includes circuitry that determines a number of resource blocks forming a resource block group, which is a unit used to allocate a resource to the communication apparatus, in a first band or in a second band that is an expanded band to which the first band is expanded, and a subcarrier spacing for the second band is same or different from a subcarrier spacing for the first band; and a transceiver that is coupled to the circuitry and that communicates with a base station using the resource. One of the number of resource blocks set for the first band and the number of resource blocks set for the second band is an integer multiple of the other, and the number of resource blocks set for the first band and the number of resource blocks set for the second band are values that are a power of two.

Abstract: A terminal includes a receiver, which, in operation, receives time unit information related to an amount of an uplink time resource per a time unit, and receives a number of repetitions over a plurality of the time units, wherein the time unit includes a downlink time resource for a downlink signal and the uplink time resource for a response signal. The amount of the uplink time resource is expressed as a fixed number of consecutive symbols that remains the same number over the plurality of the time units over which the response signal is repeatedly transmitted. The terminal includes a transmitter, which, in operation, repeatedly transmits the response signal over the plurality of the time units.
