Abstract: A method includes receiving, by a user equipment (UE) and through Radio Resource Control (RRC) signaling, information of a resource pool for a D2D communication, wherein the information of the resource pool comprises information of a discovery subframe in which a D2D discovery signal is to be communicated, determining that in the discovery subframe, the D2D discovery signal is prioritized over a communication with an evolved NodeB (eNB) unless the communication with the eNB is associated with a random access (RA) procedure, transmitting a RA preamble through a Physical Random Access Channel (PRACH), determining whether the discovery subframe corresponds to a RA subframe in which a RA response for the UE is to be monitored, and in response to determining that the discovery subframe corresponds to the RA subframe, monitoring, by the UE, the RA response during the discovery subframe.

Abstract: Exemplary embodiments provide a method and apparatus for transmitting a synchronization signal for Device-to-Device (D2D) communication in a wireless communication system. The method includes: receiving, at a first UE, a D2D synchronization signal transmitted from a second UE, the D2D synchronization signal comprising a primary D2D synchronization signal (PD2DSS) and a secondary D2D synchronization signal (SD2DSS); determining a root index based on the received PD2DSS; and determining a type of a synchronization source based on the root index. The root index corresponds to an integer value X when the type of synchronization source is associated with D2DSSue_net. The root index corresponds to an integer value Y when the type of synchronization source is associated with D2DSSue_oon. Each of the integer value X and integer value Y is not an element of a set {25, 29, 34}.

Abstract: Sidelink downlink control information (SL DCI) associated with transmission of one or more sidelink signals may be communicated. A wireless user device may transmit, based on the SL DCI and to one or more second wireless user devices, the one or more sidelink signals via a first quantity of sidelink channel resources. The wireless user device may receive first sidelink HARQ feedback information responsive to the one or more sidelink signals. The wireless user device may determine, based on a sidelink HARQ feedback timing, a time interval to transmit the first sidelink HARQ feedback information. The wireless user device may determine, based on the first quantity, a sidelink HARQ codebook. The wireless user device may transmit, during the time interval, based on the sidelink HARQ codebook, and to the base station, an uplink signal indicating the first sidelink HARQ feedback information.

Abstract: The present disclosure provides a method for performing HARQ retransmission by a terminal supporting V2X communication in a wireless communication system. The method for performing HARQ retransmission may comprise the steps of: transmitting data by a transmission terminal in a pre-configured resource; receiving, by the transmission terminal, a NACK response to the data from a reception terminal; and retransmitting the data by the transmission terminal after changing an NDI value based on a resource dynamically allocated from a base station.
