Abstract: Provided are 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), with a transmission and receipt processing method and device for time-frequency synchronization between V2X terminals. When a synchronization signal to be transmitted is identical to a synchronization signal of an existing D2D terminal, time-frequency resources configured for the D2D terminal in a cell are reused to transmit the synchronization signal. When synchronization signal to be transmitted is different from a synchronization signal of an existing D2D terminal, reconfigured time-frequency resources are used to transmit the synchronization signal. The synchronization signal transmitted by a V2X terminal indicates a corresponding synchronization source type by using a value of an SLSS sequence index and/or a value of a PSBCH specified field.

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 present disclosure relates to the technical filed of wireless communication, and particularly, to a method for random access. The method comprises the steps of transmitting a random access signal comprising a preamble sequence and a payload from a terminal to a base station, wherein the preamble sequence is configured randomly or according to size of the data to be transmitted and the payload is configured according to current service requirements; and receiving by the terminal feedback information transmitted back by the base station which corresponds to the random access signal, wherein the feedback information comprises at least one of unique user identification information, timing advance information, uplink transmission grant information, and acknowledgement (ACK) signal/negative acknowledgement (NACK) signal. The present solution may use two interactive steps to realize the function that is realized through four interactive steps in the prior art by designing the random access signal such that it comprises the preamble sequence and the payload, therefore it can reduce access delay in data transmission.
