Table 12.70.2: E-UTRAN NC with extended EARFCNs information element details

E-UTRAN NC with extended EARFCNs
This information element is included in the message to provide E-UTRAN frequencies and priority information for a mobile station supporting extended EARFCNs (see 3GPP TS 24.008).

Repeated E-UTRAN NC with extended EARFCNs

EARFCN_extended (18 bit field)
This field specifies the E-UTRA Absolute Radio Frequency Channel Number as defined in 3GPP TS 36.104. For an E-UTRAN frequency for which the corresponding EARFCN has a value below 65535, the two most significant bits (bit 17 and 18) shall be set to 0.

Measurement Bandwidth (3 bit field)
This field specifies the minimum value of the channel bandwidth of all valid E-UTRAN cells on the specified EARFCN, as defined in sub-clause 12.53.

E-UTRAN_PRIORITY (3 bit field)
THRESH_E-UTRAN_high (5 bit field)
THRESH_E-UTRAN_low (5 bit field)
If THRESH_E-UTRAN_low is not present, then THRESH_E-UTRAN_low shall take on the same value as THRESH_E-UTRAN_high.
E-UTRAN_QRXLEVMIN (5 bit field)

These fields are used for the inter-RAT cell re-selection algorithm based on priority, as defined in 3GPP TS 45.008. These values apply to each of the EARFCN values listed within this structure.
