  • Publication number: 20220312440
    Abstract: A method and apparatus are provided for managing a minimum scheduling offset for one or more bandwidth parts. A configuration for a set of one or more preconfigured minimum scheduling offset values are received (502) for a particular bandwidth part of a cell. A default minimum scheduling offset for the particular bandwidth part of the cell, that is selected from the one or more preconfigured minimum scheduling offset values of the received configuration is determined (504). The particular bandwidth part is switched (506) to from another bandwidth part. The determined default minimum scheduling offset for the particular bandwidth part is applied (508). For the particular bandwidth part, a time gap between a scheduling of a transmission for the user equipment and a physical downlink control channel in unit of slots is equal to or larger than the default minimum scheduling offset (510).
