The E-UTRAN CSG Description information element contains the description of E-UTRAN CSG cells. The fields of this description are used for inter-RAT cell reselection to E-UTRAN CSG cells as defined in 3GPP TS 45.008.

Table 12.55.2: E-UTRAN CSG description information element details

E-UTRAN_FREQUENCY_INDEX (3 bit field)
Each instance of this field describes an E-UTRAN frequency in the E-UTRAN Neighbour Cell list where the CSG PCI SPLIT is valid. If the CSG_PCI_SPLIT information element is present but there are no instances of this field present in the message, then the CSG PCI SPLIT shall apply to all E-UTRAN frequencies in the E-UTRAN Neighbour Cell list. This field is described in sub-clause 12.53.

CSG_PCI_SPLIT
This information element identifies one or more E-UTRAN physical layer cell identities (see 3GPP TS 36.211) as being reserved for CSG cells. The range of reserved physical layer cell identities applies to all E-UTRAN frequencies specified in the list of frequencies. This information element is defined as the PCID Group IE in sub-clause 12.57.
