Abstract: The present disclosure provides a wireless communication method and an eNode B and user equipment therefor. The method comprises a step of transmitting multiple PDCCH or EPDCCH repetitions respectively in multiple successive downlink subframes with a transmission repetition number and a transmission starting subframe. The transmission starting subframe is selected from a first starting subframe set corresponding to the first repetition number or a second starting subframe set corresponding to the second repetition number. The subframe indexes of any two adjacent starting subframes in the first starting subframe set are offset by a same first index interval, the subframe indexes of any two adjacent starting subframes in the second starting subframe set are offset by a same second index interval, and the second index interval is an integral multiple of the first index interval. According to the present disclosure, the resource blocking probability of different repetition numbers, UE's detection complexity can be decreased, and eNB's scheduling complexity.

Abstract: In order to provide a transmission device and transmission method with which a response signal for random access preamble transmitted from a preamble transmission device is efficiently transmitted, setting unit in base station sets a first resource candidate group, which enables terminal capable of receiving a latch response transmitted by demodulation reference signal (DMRS) transmission to be selected, and a second resource candidate group, which enables terminal incapable of receiving a latch response transmitted by DMRS transmission but capable of receiving a latch response transmitted by cell-specific reference signal (CRS) transmission to be selected. Control unit selects DMRS transmission as the latch response transmission method when a resource in which latch preamble has been received is included in the first candidate group, but selects CRS transmission as the latch response transmission method when the resource is included in the second resource candidate group.

Abstract: Provided are D2D wireless communication methods and UEs therefor. In one embodiment, the D2D wireless communication method performed by a UE includes continuing D2D transmission by using a resource from a resource pool allocated for mode 2 operation when switching from mode 1 operation to mode 2 operation. In another embodiment, the D2D wireless communication method performed by a UE includes performing D2D transmission by using a resource from a resource pool allocated for mode 2 operation, wherein the resource pool is indicated by a dedicated RRC signaling transmitted by an eNB, a SIB transmitted by an eNB, a PD2DSCH transmitted by other UE(s), and/or pre-configuration, and the dedicated RRC signaling, the SIB, the PD2DSCH and the pre-configuration are in descending order in priority when determining the resource pool.

Abstract: Provided is a receiver device that can switch between transmission methods, while minimizing increase in the number of blind decryption iterations and the amount of signaling needed for acknowledgement. In this device, a receiver part (201) receives a signal mapped to any of a plurality of mapping candidates; and according to application levels established for each of the plurality of mapping candidates, a control signal processor (205) performs blind decryption of the plurality of mapping candidates, employing either a first transmission method using a single antenna port to carry out precoding based on feedback information from the receiver device, or a second transmission method involving transmission diversity employing multiple antenna ports.

Abstract: The present disclosure mainly relates to improvements for the buffer status reporting and the logical channel prioritization procedures performed in the UE, in scenarios where the UE is in dual connectivity and the PDCP layer of the UE is shared in the uplink for MeNB and SeNB. According to the present disclosure, a ratio is introduced according to which the buffer values for the PDCP are split in the UE between the SeNB and the MeNB according to said ratio.

Abstract: The purpose of the present invention is to inhibit an increase in the amount of A/N resources, without changing the timing at which the error detection result of an SCell is notified when UL-DL configurations to be configured for each of the unit bands are different, from the timing at which the error detection result is notified when just a single unit band is configured. A control unit transmits, using a first unit band, a response signal including error detection results about data received with both the first unit band and a second unit band. In a first composition pattern set for the first unit band, an uplink communication subframe is set to be the same timing as at least an uplink communication subframe of a second composition pattern set for the second unit band.

Abstract: The present invention relates to a transmitting terminal for transmitting data to a receiving terminal over a direct link connection. The transmitting terminal comprises a receiving unit that receives from the base station a timing command for adjusting an uplink transmission timing value for data transmissions to the base station. A generating unit generates direct link timing information, based on the uplink transmission timing value, the direct link timing information being usable for generating a direct link transmission timing value for determining the timing of the data transmission over the direct link. A transmitting unit transmits to the receiving terminal the generated direct link timing information, the direct link timing information being usable at the receiving terminal for generating a direct link reception timing value for determining the reception timing of data to be received on the direct link from the transmitting terminal.
