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.

A first node receives a first reference signal group to determine a first-type received quality group; maintains a second counter according to the first-type received quality group; and transmits a first signal. The first signal indicates a first reference signal; when a first counter is no larger than a first threshold, the first reference signal belongs to a first reference signal subset; when the first counter is larger than the first threshold, the first reference signal belongs to a second reference signal subset; a reference signal in the second reference signal subset does not belong to the first reference signal subset; as a response to a first condition set being satisfied, the first signal is triggered. The method above achieves rapid cross-cell beam switch, thus guaranteeing the service quality and avoiding ping-pong effect.

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.

Abstract: The present disclosure provides a method and a device in a node for wireless communications. A first node determines a first resource set and a first resource set group from M resource sets; and monitors a first-type channel in the first resource set group in a first time window. Any two of the M resource sets are overlapping in time domain, and the first resource set group comprises the first resource set; any of the M resource sets is linked to one or two spatial states; a second resource set is any of the M resource sets different from the first resource set; whether a first condition is fulfilled is used to determine whether the second resource set belongs to the first resource set group. The above method avoids performance loss resulting from the UE's unnecessary abandonment of monitoring over some PDCCH candidates.
