Abstract: A method and a device for use in wireless communication nodes are disclosed in the present disclosure. A first node firstly performs channel listening to determine that K1 sub-bands out of K sub-bands are idle; and then transmits a first control information block and a second control information block on a first channel; the first channel occupies the K1 sub-bands of the K sub-bands; K1 repetitions of the first control information block are respectively transmitted by the K1 sub-bands, while the second control information block is transmitted only once on the first channel; the first control information block is used to indicate a sub-band occupied by the second control information block.

Abstract: The disclosure provides a method and a device used in a node for wireless communication. A first node first transmits a first sequence and a first radio signal, at least one of the first sequence or the first radio signal carrying a target identifier, then monitors a first type of information in a first time window, and finally transmits a second sequence and a second radio signal when no feedback is detected for the first sequence and the first radio signal in the first time window; wherein at least one of the second sequence or the second radio signal carries the target identifier. Through the above design, the disclosure realizes re-transmissions of a preamble and information included in a Message A in 2-step random access scenarios, thereby improving the spectrum efficiency and improving the performance of transmission of the Message A in 2-step random access scenarios.
