1. A wireless transmit/receive unit (WTRU) comprising:
a processor; and
a memory coupled with the processor, the memory storing executable instructions that when executed by the processor cause the processor to effectuate operations comprising:
communicating with two or more serving cells, wherein the two or more serving cells comprise a special cell (SpCell) and one or more secondary cells (SCells),
wherein each of the one or more SCells is in a cell state for the WTRU,
wherein the cell state comprises a deactivated state, an activated state with dormant bandwidth part (BWP), or an activated state with a non-dormant BWP,
wherein, an SCell of the one or more SCells is:
in the activated state with the dormant BWP when an active downlink (DL) BWP of the SCell is a dormant DL BWP, wherein the dormant DL BWP is the DL BWP of the SCell with a BWP identifier equal to a dormant BWP identifier configured for the SCell; or
in the activated state with the non-dormant BWP when the active DL BWP of the SCell is the non-dormant BWP;
receiving, for the SCell that is in the activated state with the non-dormant BWP, information indicating to switch to the activated state with the dormant BWP for the SCell; and
based on the information, switching to the activated state with the dormant BWP for the SCell.
