1. A method in a first-type communication node for wireless communications, comprising:
receiving first information;
receiving second information; and
transmitting 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 corresponding to the first transmission timing adjustment is not equal to a minimum step-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 second information comprises all or part of a Random Access Response (RAR), or the second information comprises all or part of a Timing Advance (TA) update; when the minimum step-size corresponding to the first transmission timing adjustment and the minimum step-size corresponding to the second transmission timing adjustment are converted into a same unit of measurement, the minimum step-size corresponding to the first transmission timing adjustment is smaller than the minimum step-size corresponding to the second transmission timing adjustment; the minimum step-size δ2 corresponding to the second transmission timing adjustment is obtained by δ2=15/SC×16×64Ts, wherein the SC is a subcarrier spacing of subcarriers occupied by the first radio signal, the Ts is equal to 1/(64×30.72×106) second.
