  • Patent number: 11291028
    Abstract: The present disclosure provides a method and a device in a User Equipment (UE) and a base station used for wireless communication. The UE receives a first signaling in a first time window in a first subband; monitors a second signaling in a second time window in a second subband; if successfully receives the second signaling in the second time window in the second subband, transmits a first radio signal in a third time window in a third subband, otherwise drops transmission of the first radio signal in the third time window in the third subband. Herein, the first signaling comprises first-type scheduling information of the first radio signal. The above method allows the base station to flexibly control a transmission time of each uplink transmission on unlicensed spectrum according to specific conditions, such as the result of LBT or the direction of beamforming.
