Abstract

The present disclosure provides a method and a device in a communication node for wireless communications. The communication node in the present disclosure first receives first information, then receives second information, and then transmits a first radio signal; wherein the first information is used to determine a first transmission timing adjustment, the second information is used to determine a second transmission timing adjustment, and a start time for a transmission of the first radio signal is related to the first transmission timing adjustment and the second transmission timing adjustment; a minimum step-size size corresponding to the first transmission timing adjustment is not equal to a minimum step-size size corresponding to the second transmission timing adjustment; the first information, the second information and the first radio signal are all transmitted through an air interface. The disclosure can support large-delay-transmission and reduce overhead for configuring signaling of Time Advance (TA).
