Abstract: Disclosed is a base station apparatus which allows an idle mode UE, in a small cell using S-NCT, to recognize the small cell and to receive a DCI. The base station apparatus is configured to use a carrier configuration which has no region for mapping a PDCCH and in which an EPDCCH is mapped in a data region. The base station apparatus includes: master information generating section 101 configured to generate allocation information indicating a resource which forms a search space in the EPDCCH and being scrambled with a cell ID of the base station apparatus; and transmitting section 107 configured to transmit the allocation information, a detection signal indicating the cell ID, and a control signal assigned in the search space.

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: The present disclosure provides a power control method in device to device (D2D) communication and a user equipment for performing the power control method. The method includes computing a power value of device to device (D2D) transmission of a user equipment performing D2D communication in a subframe in a serving cell, based on a power control adjustment state of a Long Term Evolution (LTE) wide area network (WAN) uplink channel of the user equipment and an offset or a ratio indicated by a transmit power control (TPC) command indicated in D2D grant or downlink control information (DCI) format 3/3A.

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.

Abstract: The invention relates to a method for dynamically indicating a TDD re-configuration to the mobile station by encoding the dynamic TDD re-configuration indication into the DCI or CRC calculated for the DCI. In one embodiment, the TDD configuration indication is implicitly encoded as an RNTI into the CRC, when scrambling the CRC for the DCI with a TDD-RNTI. In another embodiment, the TDD configuration indication is part of the DCI payload, while the CRC for the DCI is scrambled with a cell identifier, identifying the target cell for which the dynamic TDD re-configuration is to be applied. In still another embodiment, the TDD configuration indication is part of the DCI payload, where the DCI payload further includes an invalid parameter indicating to the mobile station that the DCI carries the TDD configuration indication.
