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.

Abstract: The present disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communications. A UE receives first information, the first information being used for indicating M DCI blind decoding(s); monitors a first-type radio signal respectively on each of S sub-band(s) in a first time-domain resource; and performs at most M1 DCI blind decoding(s) of the M DCI blind decoding(s) on the S sub-band(s) in the first time-domain resource. Herein, the first-type radio signal detected on the S sub-band(s) is used for determining the M1 DCI blind decoding(s) out of the M DCI blind decoding(s). The above method allows the base station to make dynamic adjustments to the UE's blind decoding on PDCCH resources according to LBT results, ensuring that sufficient PDCCH resources are available and not too many PDSCH resources are preempted, and that excessive blind decodings can be avoided.
