UTRAN_FREQUENCY_INDEX (5 bit field)
Each instance of this field describes a UTRAN frequency in the 3G Neighbour Cell list where the CSG PSC SPLIT is valid. If the CSG_PSC_SPLIT IE is present but there are no instances of this field present in the message, then the CSG PSC SPLIT shall apply to all UTRAN frequencies in the 3G Neighbour Cell list. This field is described in sub-clause 12.52.

CSG_PSC_SPLIT
This information element identifies one or more primary scrambling code values for UTRAN FDD cells (see 3GPP TS 25.213) or cell parameter values for UTRAN TDD cells (see 3GPP TS 25.223) as being reserved for CSG cells. The range of reserved primary scrambling codes or cell parameters applies to all UTRAN frequencies specified in the list of frequencies.
This information element is defined as the PSC Group IE described in subclause 12.58.
