Bandwidth part (BWP) switching

Abstract:

User equipment (UE) includes processing circuitry coupled to memory. To configure the UE for active bandwidth part (BWP) switching, the processing circuitry is to decode RRC signaling configuring a plurality of BWPs for the UE. The RRC signaling further includes an indicator for an initial BWP of the plurality of BWPs for initial use by the UE as an active BWP. DCI received on a PDCCH is decoded, which includes a BWP indicator for switching the active BWP from the initial BWP to another BWP of the plurality of BWPs. RF and baseband parameters to switch the active BWP from the initial BWP to the another BWP are reconfigured. Reconfiguring the RF and baseband parameters cause an interruption of one or more slots of a serving cell of the UE. A starting time of the interruption is within a time duration of a BWP switching delay supported by the UE.
