摘要： 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.

摘要： Embodiments of the present disclosure provide a resource selection or reselection method by a user equipment (UE) and the UE in Vehicle to vehicle/pedestrian/infrastructure/network (V2X) communication. The method comprises the steps of: detecting physical sidelink control channel (PSCCH) transmitted by other UE(s); selecting (a) single-subframe resource(s) from single-subframe resources which do not overlap with single-subframe resources reserved by the detected PSCCH; and transmitting physical sidelink shared channel (PSSCH) on the selected single-subframe resource(s).

摘要： The present application discloses a method of determining scheduling of shortened subframes. The method includes: a UE determines a time-frequency position of a candidate PDCCH/EPDCCH which schedules PDSCH/PUSCH of a shortened subframe; the UE performs a pre-determined number of blind detections of the candidate PDCCH/EPDCCH at the time-frequency position. The present application also provides a device. The technical mechanism of the present application can make shortened subframes to function normally, thereby reduce time delay in data transmission.
