The present disclosure provides a method and a device in a communication node used for wireless communications. A communication node receives first information and second information; and transmits a first radio signal, an SCS of a subcarrier occupied by the first radio signal is equal to a first SCS; a sum of a first timing adjustment and a second timing adjustment is used to determine a transmission timing for the first radio signal, and the first timing adjustment is used to determine a transmission timing for a radio signal transmitted earlier than the first radio signal; the second timing adjustment is equal to a sum of a first sub-adjustment and a second sub-adjustment, the first information is used to determine the first sub-adjustment, and the second information is used to determine the second sub-adjustment. The present disclosure improves scheduling flexibility.
