In one embodiment, the method includes the UE being configured with a first cell. 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. ## Claims ### Claim 1 A method for a UE (User Equipment), comprising: the UE is configured with a first cell; the UE is configured with a second cell; the UE changes 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; and the UE transmits 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. ### Claim 2 (depends on 1) The method of claim 1, wherein the first cell is PCell (Primary Cell) or PSCell (Primary Secondary Cell), and the second cell is SCell (Secondary Cell). ### Claim 3 (depends on 1) The method of claim 1, wherein the UE does not change active uplink BWP of the first cell, and the UE does not change active downlink BWP of the second cell. ### Claim 4 (depends on 1) The method of claim 1, wherein the UE transmits a HARQ-ACK associated to the second occasion. ### Claim 5 (depends on 1) The method of claim 1, wherein the UE receives PDSCH (Physical Downlink Shared Channel) or PDCCH (Physical Downlink Control Channel) indicating SPS (Semi-Persistent Scheduling) release on the first occasion. ### Claim 6 (depends on 1) The method of claim 1, wherein the UE receives PDSCH (Physical Downlink Shared Channel) or PDCCH (Physical Downlink Control Channel) indicating SPS (Semi-Persistent Scheduling) release on the second occasion. ### Claim 7 (depends on 1) The method of claim 1, wherein the UE does not receive PDSCH (Physical Downlink Shared Channel) nor PDCCH (Physical Downlink Control Channel) indicating SPS (Semi-Persistent Scheduling) release on the first occasion. ### Claim 8 (depends on 1) The method of claim 1, wherein the UE does not receive PDSCH (Physical Downlink Shared Channel) nor PDCCH (Physical Downlink Control Channel) indicating SPS (Semi-Persistent Scheduling) release on the second occasion. ### Claim 9 (depends on 1) The method of claim 1, wherein the first occasion is in a first set of occasions associated with the slot, wherein the first set of occasion refers to a default set and/or DL-data-DL-acknowledgement for the first cell; and wherein the second occasion is in a second set of occasions associated with the slot, wherein the second set of occasion refers to a default set and/or DL-data-DL-acknowledgement for the second cell. ### Claim 10 (depends on 1) The method of claim 1, wherein the UE is configured to transmit HARQ-ACK of the first cell and HARQ-ACK of the second cell on the first cell. ### Claim 11 A method for a UE (User Equipment), comprising: the UE is configured with a first cell; the UE is configured with a second cell; the UE changes active downlink BWP (Bandwidth Part) of the second 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 second cell, and a second occasion in the second cell is prior to finishing the change of active downlink BWP of the second cell; and the UE transmits 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 first occasion and not associated with the second occasion. ### Claim 12 (depends on 11) The method of claim 11, wherein the first cell is PCell (Primary Cell) or PSCell (Primary Secondary Cell), and the second cell is SCell (Secondary Cell). ### Claim 13 (depends on 11) The method of claim 11, wherein the UE does not change active uplink BWP of the first cell, and the UE does not change active downlink BWP of the first cell. ### Claim 14 (depends on 11) The method of claim 11, wherein the UE transmits a HARQ-ACK associated to the first occasion. ### Claim 15 (depends on 11) The method of claim 11, wherein the UE receives PDSCH (Physical Downlink Shared Channel) or PDCCH (Physical Downlink Control Channel) indicating SPS (Semi-Persistent Scheduling) release on the first occasion. ### Claim 16 (depends on 11) The method of claim 11, wherein the UE receives PDSCH (Physical Downlink Shared Channel) or PDCCH (Physical Downlink Control Channel) indicating SPS (Semi-Persistent Scheduling) release on the second occasion. ### Claim 17 (depends on 11) The method of claim 11, wherein the UE does not receive PDSCH (Physical Downlink Shared Channel) nor PDCCH (Physical Downlink Control Channel) indicating SPS (Semi-Persistent Scheduling) release on the first occasion. ### Claim 18 (depends on 11) The method of claim 11, wherein the UE does not receive PDSCH (Physical Downlink Shared Channel) nor PDCCH (Physical Downlink Control Channel) indicating SPS (Semi-Persistent Scheduling) release on the second occasion. ### Claim 19 (depends on 11) The method of claim 11, wherein the first occasion is in a first set of occasions associated with the slot, wherein the first set of occasion refers to a default set and/or DL-data-DL-acknowledgement for the first cell; and wherein the second occasion is in a second set of occasions associated with the slot, wherein the second set of occasion refers to a default set and/or DL-data-DL-acknowledgement for the second cell. ### Claim 20 (depends on 11) The method of claim 11, wherein the UE is configured to transmit HARQ-ACK of the first cell and HARQ-ACK of the second cell on the first cell.
