    Abstract: According to an embodiment of this disclosure, a method for transmitting and receiving a signal in a device of a mobile communication system includes steps of receiving, from a base station, a first message containing one or more of synchronization information and resource allocation information; transmitting, to other device, a second message containing the received synchronization information and resource allocation information; and receiving, from the other device, a third message for a random access based on the synchronization information and the resource allocation information. According to an embodiment of the present disclosure, even a device failing to obtain synchronization can obtain synchronization from a base station through other device, receive authentication and security related information, and thereby perform reliable D2D communication. Also, a communication efficiency can be improved by transmitting and receiving D2D related information between devices through limited resources.

    Abstract translation: 根据本公开的实施例，一种用于在移动通信系统的设备中发送和接收信号的方法包括以下步骤：从基站接收包含同步信息和资源分配信息中的一个或多个的第一消息; 向其他设备发送包含所接收的同步信息和资源分配信息的第二消息; 以及基于所述同步信息和所述资源分配信息从所述另一设备接收用于随机接入的第三消息。 根据本公开的实施例，即使未能获得同步的设备也可以从基站通过其他设备获得同步，接收认证和安全相关信息，从而执行可靠的D2D通信。 此外，通过有限的资源在设备之间发送和接收D2D相关信息，可以提高通信效率。

    Abstract: The present disclosure relates to a pre-fifth generation (5G) or 5G communication system to be provided for supporting higher data rates beyond fourth generation (4G) communication system such as long term evolution (LTE).A synchronization signal transmission/reception method for use in a device-to-device (D2D) communication system is provided. A method of transmitting a synchronization signal for D2D communication in an asynchronous network, in which a first terminal located in a first cell controls synchronization with a second terminal located outside of the first cell, includes transmitting, at the first cell, a system information block (SIB) including resource allocation information of the first cell and at least one neighboring cell, determining whether the first terminal is in a first mode and whether the first terminal is scheduled to perform one of a D2D communication and a D2D discovery; determining, when the first terminal is in the first mode, whether the first terminal is required to transmit a D2D synchronization signal (D2DSS); and transmitting, when the first terminal is required to transmit the D2DSS, scheduling information including a transmission time point and transmission reference timing information to the first terminal.

    Abstract: The disclosure relates to converging a 5G communication system for supporting higher data rates beyond a 4G system with a technology for IoT, and may be applied to intelligent services based on the 5G communication technology and IoT-related technology. The disclosure provides a method performed by a UE in a communication system. The method includes receiving, via higher layer signaling, a configuration of PUSCH repetition; receiving, on a PDCCH, DCI including a TDRA field; identifying, based on the configuration and the TDRA field, a plurality of time resources for the PUSCH repetition; identifying whether predefined conditions are satisfied; and transmitting, on the plurality of time resources, the PUSCH repetition while maintaining power consistency for the PUSCH repetition in case that the predefined conditions are satisfied. The predefined conditions include a first predefined condition corresponding to frequency hopping being not configured for the PUSCH repetition.

    Abstract: The disclosure relates to a communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with a technology for IoT. A method of a base station includes determining a contention window for a sub-band among multiple sub-bands based on hybrid automatic repeat request-acknowledgement feedbacks corresponding to physical downlink shared channels (PDSCHs) in a reference duration, identifying a number for the sub-band between zero and the contention window, sensing the sub-band based on the number and a defer duration, and performing a downlink transmission based on sensing the sub-band to be idle, wherein the reference duration starts from a beginning of a channel occupancy and ends at a first slot where at least one of the PDSCHs is transmitted, and wherein the PDSCHs in the reference duration include a PDSCH that partially but not fully overlaps with the sub-band among the multiple sub-bands and a PDSCH that fully overlaps with the sub-band among the multiple sub-bands.
