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). A method for determining transmitting resources in vehicle to vehicle/pedestrian/infrastructure/network (V2X) communication is provided. The method includes determining, by a user equipment (UE), a set {ti} consisting of configurable V2X subframes within one system frame period, by the UE, determining information about a bitmap for configuring a resource pool, determining, in the set {ti}, subframes belonging to the resource pool, by the UE, selecting, after resource reselection, the position of a resource for initial transmission, determining, in the resource pool, the subframe position of the reserved resource according to a resource reservation subframe interval Prsv and the number of resource reservations, readjusting the position of the reserved resource when a certain condition is satisfied, and transmitting, by the UE, a physical sidelink shared channel (PSSCH) on the determined resource for initial transmission and the reserved resource.

Abstract: The present invention provides a control information transmission resource determining method in a D2D communication. In this method, a location of a subframe used for a SA transmission is determined in a SA resource pool by a TRP. In the subframe, a frequency domain resource used for the SA transmission occupies a part of symbols or PRBs in the entire subframe, and a location of the frequency domain resource is determined by a central control node assigning way, a randomly selecting way, a resource-hopping way or a mapping way between a time domain resource and a frequency domain resource. According to the method above, data transmission delay can be effectively reduced, data transmission reliability can be ensured, and V2X communication requirements can be achieved by small changes in a current system.
