Abstract: The present disclosure discloses a method and device used in wireless communication node. A first node receives first information and second information via an air interface, the first information indicating a first time offset value, and the second information indicating a first time-domain resource relative to a first instant of time; the first instant of time is associated with a first time unit. By designing the first time offset value in the present disclosure, whenever a terminal A expects a terminal B to transmit, the terminal B is able to transmit according to a timing obtained by itself and there is no need for multiple interactions between these terminals to acquire a timing advance (TA), thus improving radio signal transmission efficiency on sidelink in IOT and V2X systems and the system's overall performance.
