16.13.5 BWP operation
An (e)RedCap UE in RRC_IDLE or RRC_INACTIVE monitors paging only in an initial BWP (default or RedCap specific) associated with CD-SSB and performs cell (re-)selection and related measurements on the CD-SSB. If a RedCap-specific initial UL BWP is configured and NUL is selected, (e)RedCap UEs shall use only the RedCap-specific initial UL BWP to perform RACH procedure in RRC_IDLE and RRC_INACTIVE or to perform CG-SDT procedure (as described in clause 18.0) in RRC_INACTIVE.
An (e)RedCap UE may be configured with multiple NCD-SSBs provided that each BWP is configured with at most one SSB. NCD-SSB may be configured for an (e)RedCap UE in RRC_CONNECTED to perform RLM, BFD, and RRM measurements and RA resource selection when the active BWP does not contain CD-SSB.
An (e)RedCap UE may be configured with NCD-SSB for a RedCap-specific initial DL BWP to perform SDT procedure in RRC_INACTIVE (as described in clause 18.0) in case the RedCap-specific initial DL BWP does not contain CD-SSB.
