    Abstract: The present invention relates to a method for performing a D2D discovery and a terminal using the same. Particularly, the present invention relates to a method for performing a D2D discovery, which compares a congestion level of another discovery slot selected randomly or according to a preset pattern with a threshold or a congestion level of a current discovery slot and determines a discovery slot to transmit a discovery message and a transmission period of the discovery message according to a result of the comparison, and a terminal using the same. The present invention relates to a method for performing a D2D discovery using discovery resources including a plurality of discovery slots, and a terminal performing the same, the method comprising the steps of: broadcasting a discovery message by using a first discovery slot; comparing a congestion level of a selected second discovery slot with a predetermined congestion level value; determining a discovery slot to broadcast the discovery message on the basis of a result of the comparison; and broadcasting the discovery message by using the determined discovery slot.

    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A method and an apparatus that may repeatedly transmit signals to cope with and reduce transmission errors in device-to-device (D2D) communication are provided. The method includes receiving, upon generation of data to be transmitted to a receiving user equipment (UE) (RX UE), allocation of resources to be used for D2D communication, transmitting a scheduling assignment (SA) containing identification information of at least one RX UE to the at least one RX UE, assigning at least one hybrid automatic repeat request (HARQ) process for the identification information of the at least one RX UE, and transmitting data to the at least one RX UE based on the HARQ process. Accordingly, it is possible to remove factors causing system performance degradation when retransmission operation for communication between a UE and a base station (eNB) is introduced to D2D communication.

    Abstract translation: 本公开涉及提供用于支持更高数据速率的第5代（5G）或5G通信系统超越第四代（4G）通信系统，例如长期演进（LTE）。 提供了可以重复发送信号以处理并减少设备到设备（D2D）通信中的传输错误的方法和装置。 该方法包括在生成要发送到接收用户设备（UE）（RX UE）的数据时，接收用于D2D通信的资源的分配，发送包含至少一个RX的标识信息的调度分配（SA） UE至少一个RX UE，为至少一个RX UE的识别信息分配至少一个混合自动重传请求（HARQ）过程，以及基于HARQ进程向至少一个RX UE发送数据。 因此，当将UE和基站（eNB）之间的通信的重传操作引入到D2D通信时，可以去除导致系统性能下降的因素。

    Abstract: The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates. The present disclosure relates to a method performed by a terminal in a wireless communication system, wherein the method may comprise the steps of: receiving scheduling information, for the repeated transmission of a physical uplink shared channel (PUSCH), from a base station through a first signal; setting a time period, in which a signal for transmit power control (TPC) can be received and applied, for each of one or more PUSCHs scheduled through the first signal; and performing power control for the PUSCH transmissions corresponding to the set time periods on the basis of second signals received from a base station within the set time periods.

    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. More particularly, disclosed is a method and apparatus for performing resource selection and signal transmission or reception for positioning between UEs. According to various embodiments, a method performed by a first user equipment (UE) in a wireless communication system, the method comprising: transmitting, to a second UE, a first sidelink positioning reference signal (SL PRS); receiving, from the second UE, a second SL PRS; and identifying a SL PRS time difference based on the first SL PRS and the second SL PRS, wherein the SL PRS time difference is a difference between a received timing of a sidelink subframe #i associated with the first SL PRS and a transmit timing of a sidelink subframe #j associated with the second SL PRS, according to an indication via a higher layer signaling.
