The present disclosure provides a method and device in a communication node for wireless communications. A communication node receives a first signaling; transmits a first signal; receives a second signal; transmits a third signal; and when a first condition is satisfied, transmits a fourth signal; the first signaling comprises K1 first-type signal(s) and K2 second-type signal(s); the K1 first-type signals(s) is(are) different from the K2 second-type signal(s); a sum of K1 and K2 is of a fixed magnitude; the K1 and the K2 are both positive integers; the first signal is one of the K1 first-type signal(s); the fourth signal is one of the K2 second-type signal(s); the second signal is used for determining time-frequency resources of the third signal; the first condition is related to a parameter of the third signal. The present disclosure allows that a preamble group is reselected to improve probability of random access success.
