Abstract: Provided are a method, carried out by a terminal, for transmitting a physical sidelink broadcast channel (PSBCH) and a terminal utilizing the method. The method determines whether the terminal is in or out of cell coverage, and whether a discovery signal to be transmitted by the terminal is a public safety (PS) discovery signal for PS. If the terminal is outside the cell coverage and is to transmit a PS discovery signal, then when a sidelink synchronization signal (SLSS) is transmitted in a discovery period, a PSBCH is also transmitted therewith.

Abstract: A method and corresponding apparatus, where the apparatus transmits, to a user equipment (UE), downlink control information (DCI) including a downlink assignment index (DAI) through an enhanced physical downlink control channel (E-PDCCH). The DCI transmitted through the E-PDCCH includes an additional field which is not present in DCI transmitted through a physical downlink control channel (PDCCH). If the DAI value included in the DCI is greater than 1, the additional field is used to determine a single resource for the ACK/NACK among the plurality of PUCCH resources configured by a higher layer signal.

Abstract: The present invention discloses a method for transmitting a reception acknowledgement response in a wireless communication system. The method includes receiving an enhanced physical downlink control channel (EPDCCH), determining a physical uplink control channel (PUCCH) resource based on a lowest one of enhanced control channel element (ECCE) indexes configuring the EPDCCH and a HARQ-ACK resource offset (ARO), and transmitting a reception acknowledgement response through the PUCCH resource. When a reception acknowledgement response related to two or more subframes is transmitted in a subframe for transmission of the reception acknowledgement response, a set of possible values for the ARO includes a first ARO value to shift a PUCCH resource of a specific subframe to a PUCCH resource region for at least one subframe prior to the specific subframe. The first ARO value provides a different shift amount depending on a group having the specific subframe among groups related to the two or more subframes.
