Patent ID: 11617195

Abstract:
A method and apparatus are disclosed from the perspective of a User Equipment (UE). In one embodiment, the method includes the UE being configured with a first DL (Downlink) BWP (Bandwidth Part) and a second DL BWP. The method also includes the UE receiving and/or monitoring a DCI (Downlink Control Information) in a scheduling CORESET (Control Resource Set) in the first DL BWP, and for determining size of the DCI for decoding, the UE determines whether a TCI (Transmission Configuration Indication) field is present in the DCI or not based on a parameter of the scheduling CORESET before the UE decodes the DCI successfully. The method further includes the UE truncates or pads zero-bits to at least one field (other than the TCI field) in the DCI based on configuration of the second DL BWP after the UE decodes successfully the DCI, wherein a BWP indicator field in the DCI indicates the second DL BWP different from the first DL BWP. In addition, the method includes the UE determines whether the TCI field is present in the DCI or not based on the parameter of the scheduling CORESET in the first DL BWP after the UE decodes successfully the DCI, wherein a BWP indicator field in the DCI indicates the second DL BWP different from the first DL BWP.
