The method further includes the UE being configured with a second cell. The method includes the UE changing active downlink BWP (Bandwidth Part) of the first cell from a first downlink BWP to a second downlink BWP, wherein a first occasion in the first cell is prior to finishing the change of active downlink BWP of the first cell, and a second occasion in the second cell is prior to finishing the change of active downlink BWP of the first cell. In addition, the method includes the UE transmitting an uplink signal in a slot on the first cell after the change of active downlink BWP, wherein the uplink signal comprises HARQ-ACK (Hybrid Automatic Repeat Request Acknowledgment) associated with the second occasion and not associated with the first occasion.
