Abstract
The disclosure discloses a method and device in a user equipment and a base station for wireless communication. The UE performs K channel listening in K sub-bands, respectively; determines that a first radio signal can only be transmitted in K1 sub-band(s) out the K sub-bands; and transmits the first radio signal in the K1 sub-band(s), wherein the K channel listening is used to determine the K1 sub-band(s) from the K sub-bands; the first radio signal comprises K1 first sub-signal(s) transmitted in the K1 sub-band(s), respectively; each of the K1 first sub-signal(s) carries a first bit block, the first bit block comprises a positive integer number of bits, and a number of REs occupied by any one of the K1 first sub-signal(s) in a time-frequency domain is correlated with the K1. The method not only ensures the reliability of uplink transmission but also avoids waste of resources in an NR-U system.
