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 disclosure provides a method for RLM and a corresponding UE. The method comprises the steps of: determining, by a UE and on a carrier used for RLM, whether a reference signal transmitted by a base station for RLM is received in any subframe; performing RLM based on the reference signal if the reference signal transmitted by the base station is received in any subframe; and, determining, according to a result of RLM, whether link failure is detected. With the solutions, a link state capable of accurately reflecting the actual link quality can be acquired, so that a higher layer of a UE can timely make a decision on link failure or link recovery.
