Abstract: A method and apparatus for autonomous changing for dormant bandwidth part in a wireless communication system is provided. A wireless device configures a cell group including a certain cell on which a PUCCH is configured. A wireless device activates a dormant BWP of the certain cell to be an active BWP of the certain cell, wherein no PDCCH is configured on the dormant BWP. A wireless device switches the active BWP of the certain cell from the dormant BWP to another BWP upon triggering the scheduling request procedure, wherein at least one PDCCH is configured on the other BWP.
