Abstract: The present invention relates to a user device, a base station, and data transmission and reception methods to be performed by a user device and a base station in a communications system. The user device comprises circuitry which, in operation, calculates the starting location of a paging region comprising resources in which user devices are paged, the paging region including paging information for paging said user device; and determines an offset with respect to the starting location of the paging region, the offset indicating the location of the paging information for paging said user device relative to the starting location of the paging region.

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: A communication apparatus includes control circuitry and a transmitter. In operation, the control circuitry selects a Demodulation Reference Signal (DMRS) mapping pattern from among a plurality of DMRS mapping patterns. The DMRS mapping patterns include a first DMRS mapping pattern with first DMRS resource elements to which first DMRSs in a first half of a subframe are mapped and second DMRS resource elements to which second DMRSs in a second half of the subframe are mapped. Also, in operation, the transmitter transmits downlink control information that includes a plurality of bits indicating the selected DMRS mapping pattern.

Abstract: The invention relates to a transmitting device, which performs a resource sensing procedure to acquire information about radio resources usable for transmitting data at a later point in time. After data becomes available for transmission, the transmitting device performs an autonomous radio resource allocation to select radio resources within a transmission window to be used for transmitting the data, based on the information acquired by the resource sensing procedure during a sensing window. The autonomous radio resource allocation comprises selecting radio resources in primary subframes of the transmission window preferably over radio resources in secondary subframes of the transmission window. The secondary subframes correspond to those subframes in the sensing window during which the transmitting device did not perform the resource sensing procedure, and the primary subframes correspond to those subframes in the sensing window during which the transmitting device did perform the resource sensing procedure.

Abstract: A self-contained operation using a time-unit configuration taking into consideration HARQ processes is performed. In base station, transmission section transmits a downlink signal in a downlink transmission region in a time unit composed of the downlink transmission region, an uplink transmission region, and a gap interval that is a switching point from the downlink transmission region to the uplink transmission region; and reception section receives an uplink signal in the uplink transmission region in the time unit. Each time unit includes the downlink transmission region and the uplink transmission region for each of HARQ processes.

Abstract: The invention relates to an improved radio resource allocation performed by a vehicular mobile terminal. The vehicular mobile terminal determines whether to determine radio resources based on the location of the vehicular mobile terminal or not, based on information received from an entity of the communication system. In case the radio resources are to be selected based on the location of the vehicular mobile terminal, the vehicular mobile terminal determines the location of the vehicular mobile terminal, and determines radio resources for communication with at least the second mobile terminal, based on the determined location of the vehicular mobile terminal.

Abstract: Disclosed is a terminal that performs an appropriate transmission power control for both signals intended for a base station and for D2D communication. The terminal includes: a reception processing section that receives a control signal including a TPC command selected from among a plurality of candidate values; and a transmission power control section that controls a first transmission power for an uplink data signal for a base station, using a first correction value corresponding to the received TPC command, and that controls a second transmission power for a signal for D2D communication using the first correction value or a second correction value corresponding to the received TPC command. In the terminal, the first and the second correction values are set for each candidate value of the TPC command; and the second correction value is set lower than the first correction value for at least one of the candidate values.
