Abstract: A communication method and system for converging a fifth generation (5G) communication system for supporting higher data rates beyond a fourth generation (4G) system with a technology for Internet of things (IoT) are provided. A method of a terminal for performing a random access procedure in this manner includes transmitting a random access preamble to a base station, receiving a random access response (RAR) from the base station, and identifying whether each media access control (MAC) sub-protocol data unit (subPDU) in the received RAR includes a random access preamble identifier (RAPID) corresponding to the random access preamble. The RAR includes a plurality of MAC subPDUs including the RAPID corresponding to the random access preamble.

Abstract: Embodiments herein disclose a method for identifying a unicast Device to Device (D2D) communication. Further, the method includes generating, by a source User Equipment (UE), a D2D Media Access Control (MAC) Protocol Data Unit (PDU) comprising a unicast parameter. Further, the method includes transmitting, by the source UE, the D2D MAC PDU to the destination UE. Further, the method includes receiving, by the destination UE, the D2D MAC PDU. Further, the method includes detecting, by the destination UE, one of unicast parameters and groupcast parameters of the D2D MAC PDU. Furthermore, the method includes identifying, by the UE, the D2D MAC PDU is for one of the unicast D2D communication when the unicast parameters are detected, and the groupcast D2D communication when the groupcast parameters are detected.

Abstract: A method of a UE is provided. The method includes receiving, from a base station, first information of a first timer of a bandwidth part inactivity associated with a bandwidth part of a primary cell (PCell) and second information of a second timer of a bandwidth part inactivity associated with a bandwidth part of a secondary cell (SCell), identifying that a random access procedure is initiated on the PCell or the S cell, stopping the first timer, if running, in response to identifying that the random access procedure is initiated on the Pcell, and stopping the first timer and the second timer, if running, in response to identifying that the random access procedure is initiated on the SCell. The method relates to a communication method and system for converging a 5th-Generation communication system for supporting higher data rates beyond a 4th-Generation system with a technology for Internet of Things (IoT).

Abstract: A method and system for differentiating different Protocol Data Units (PDU) in a D2D communication network. The type of PDU to be differentiated is assigned/associated with a unique data/value and transmitted to the destination, by a transmitting User Equipment. At the receiving end, the receiving User Equipment differentiates between different types of PDU packets received, based on the unique data associated with the collected data. Further, the received PDU data is processed based on a suitable packet processing function that matches the PDU type of the PDU data received.

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. The method for device to device communication according to the present disclosure comprises: a step of receiving, by a terminal, search data from search resources for relay search within a specified search-receiving resource pool, and decoding the same; a step of measuring, by the terminal, link qualities of the search resources which deliver demodulation reference signals, from the search resources corresponding to successfully decoded search data; and a step of filtering a link quality corresponding to an identifier of a specific relay among the measured link qualities.

Abstract: The present disclosure relates to a communication technique for converging an IoT technology with a 5G communication system to support a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure can be applied to intelligent services (e.g., a smart home, a smart building, a smart city, a smart or connected car, health care, digital education, retail business, and services associated with security and safety, or the like) on the basis of 5G communication technology and an IoT-related technology. The present invention provides a method for determining a radio link failure. The method comprises the steps of: identifying an indication of in synchronization (IS) or out of synchronization (OOS) with respect to a plurality of reception beams; starting a timer to determine a radio link failure when the indication of OOS is identified; and holding the timer when at least one of the plurality of reception beams is requested to be changed.

Abstract: The present disclosure relates to fifth generation (5G) or pre-5G communication systems provided to support a higher data rate than that given by long term evolution (LTE) or other post-fourth generation (4G) communication systems. A method for performing a sidelink communication by a terminal is provided. The method includes sending, to a base station, a request for multiple grants for the sidelink communication and a first indicator indicating whether the terminal supports multiple transmissions of the sidelink communication to different destinations in a sidelink control (SC) period, receiving the multiple grants from the base station, and performing the multiple transmissions to the different destinations in the SC period.
