# sib5 configuration options (See TS 36.331)
# Contains information relevant for inter-frequency cell re-selection.
# Must be added to sib1::sched_info::si_mapping_info array parameter to be transmitted
#
# inter_freq_carrier_freq_list: A list of neighbouring inter-frequencies.
# dl_carrier_freq: The EARFCN for the EUTRA carrier frequency.
# q_rx_lev_min: Minimum received RSRP level in the E-UTRA cell, ([field_val] * 2) = [level in dBm].
# p_max: Optional maximum allowed transmission power for the neighbouring E-UTRA cells on this carrier frequency.
# t_resel_eutra: Cell reselection timer (seconds).
# t_resel_eutra_sf: Optional speed dependent ScalingFactor for t_resel_eutra.
# sf_medium: Scaling factor if the UE is in Medium Mobility state, one of "0.25", "0.5", "0.75" or "1.0".
# sf_high: Scaling factor if the UE is in High Mobility state, one of "0.25", "0.5", "0.75" or "1.0".
# thresh_x_high: Srclev threshold (dB) to select to a higher-priority RAT/Frequency.
# thresh_x_low: Srclev threshold (dB) to select to a lower-priority RAT/Frequency.
# allowed_meas_bw: Maximum allowed measurement bandwidth on a carrier frequency .
# presence_ant_port_1: whether all the neighbouring cells use Antenna Port 1.
# cell_resel_prio: Optional absolute priority of the carrier frequency group.
# neigh_cell_cfg: Information related to MBSFN and TDD UL/DL configuration of neighbour cells.
# q_offset_freq: Frequency specific offset for equal priority E-UTRAN frequencies.
# inter_freq_neigh_cell_list: A List of inter-frequency neighbouring cells with specific cell re-selection parameters.
# phys_cell_id: Physical layer identity of the cell.
# q_offset_cell: Cell spcific offset.
# inter_freq_black_cell_list: A List of blacklisted inter-frequency neighbouring cells.
# start: The lowest physical cell identity in the range.
# range: The number of physical cell identities in the range.
