ASUSTeK Computer has filed a patent for a method that allows a User Equipment (UE) to change the active uplink bandwidth part (BWP) of a primary cell (PCell) before a first slot. The UE is configured with first Physical Uplink Control Channel (PUCCH) resources on the PCell and second PUCCH resources on a secondary cell (SCell). The method involves generating a Hybrid Automatic Repeat request (HARQ) codebook and determining whether to include HARQ information based on the cell associated with the changing BWP. The UE then transmits a PUCCH including the HARQ codebook on the SCell in the first slot.

Method for changing ul bandwidth part and transmitting pucch
A recently filed patent (Publication Number: US20230319790A1) describes a method for User Equipment (UE) that is configured with multiple Physical Uplink Control Channel (PUCCH) resources on both a primary cell (PCell) and a secondary cell (SCell). The method involves changing the active uplink bandwidth part (BWP) of the PCell before a first slot, while also changing the active UL BWP of the SCell. The first slot is associated with both the PCell and the SCell.
The method also includes generating a Hybrid Automatic Repeat request (HARQ) codebook. This involves including HARQ information associated with the second occasion in the HARQ codebook when the UE transmits a first PUCCH on the SCell in the first slot. However, when the UE transmits a second PUCCH on the PCell in the first slot, the HARQ codebook does not include HARQ information associated with the first occasion and the second occasion.
The patent also mentions the possibility of the UE being configured with a third cell without PUCCH resources in the PUCCH group. This third cell can be another SCell. The method further includes determining that the first occasion, the second occasion, and the third occasion are associated with the first slot based on information indicated by one or more Downlink Control Informations (DCIs) for deriving the first slot.
Additionally, the patent describes that the size of the HARQ codebook can be determined based on the measure of occasions of different sets of occasions associated with the PCell, SCell, and the third cell. The HARQ codebook can have multiple locations, with each location corresponding to HARQ information or being associated with an occasion from the different sets of occasions.
The patent also includes a description of a User Equipment (UE) that is configured with PUCCH resources on a primary cell (PCell) and a PUCCH-switching secondary cell (PUCCH-sSCell). The UE includes a control circuit, a processor, and a memory. The processor is configured to execute a program code stored in the memory to perform operations, including changing the active UL BWP of the PCell and the PUCCH-sSCell before a first slot and generating a HARQ codebook.
In summary, the patent describes a method and a User Equipment (UE) configuration for managing PUCCH resources on both a primary cell and a secondary cell. The method involves changing the active UL BWP of the cells before a first slot and generating a HARQ codebook with specific inclusion or exclusion of HARQ information based on the cell and PUCCH transmission. The UE configuration includes a control circuit, processor, and memory to execute the method.
