    Abstract: The present disclosure relates to a communication method and system for converging a 5th-generation (5G) communication system for supporting higher data rates beyond a 4th-generation (4G) system with a technology for internet of things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method for receiving system information (SI) by a user equipment (UE) in a wireless communication system is provided. The method includes receiving, from a base station (BS), first type SI associated with SI which is essential for communication with the BS, transmitting, to the BS, a physical random access channel (PRACH) preamble based on the first type SI, receiving, from the BS, a random access response (RAR) message, and receiving, from the BS, second type SI associated with at least one SI which the UE needs.

    Abstract: A system and a method for a base station to reduce signaling overhead in device-to-device (D2D) communication are provided. The method includes a list of one or more destination identities (IDs) in a signaling message from at least one of UE and source base station, receiving a destination index in a buffer status report (BSR) from UE to request dedicated resources for transmitting D2D communication packets to a destination, determining the destination ID corresponding to destination index received in the BSR using the list of one or more destination IDs received from at least one of UE and source base station wherein the destination index is the index of destination ID in the list of destination IDs received, and allocating resources to the UE based on the determined destination ID.

    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). The various embodiments of the present invention disclose a method of secured transmission and reception of discovery message in device to device (D2D) communication system. According to one embodiment, a transmitting user equipment (UE) receives a ProSe group key (PGK) from a Prose function to perform a D2D communication in a D2D public safety group. The transmitting UE then derives a ProSe traffic key (PTK) using the PGK for transmitting data packets in the D2D communication. Using the PTK, the transmitting UE further derives a Prose integrity protection key (PIK) for securing a discovery message to discover one or more receiving UEs. The transmitting UE transmits the integrity protected discovery message using the derived PIK to the receiving UE. In turn, the receiving UE transmits a response message in a secure manner by deriving a PIK using PGK configured for the receiving UE. The various embodiments of the present invention disclose a method of a terminal. According to one embodiment, the method comprises of deriving a first traffic key and a second traffic key based on a group key, deriving a first security key for securing a discovery message based on the first traffic key and a second security key for securing data packets based on the second traffic key, and transmitting the discovery message generated based on the first security key.

    Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. A security problem in which information of a monitoring device is provided to another PLMN exists in the procedure for connecting ProSe Functions of two PLMNs and transmitting and receiving information therebetween, and thus, configuration of a D2D discovery service between different providers (inter PLMN) is difficult in reality, despite being defined in the standard. Therefore, the present invention provides a method of using a content server with an existing D2D discovery method in order to advertise, through D2D discovery, real-time local area advertisements to device of a plurality of providers. A monitoring device requests advertisement information directly from a content server, or requests advertisement information from a different PLMN ProSe Function, and thereby the other PLMN ProSe Function may request advertisement information from a content server.
