Downlink Channel (UARFCN)

Last updated: February 3, 2009

DL Channel

The DL Channel setting specifies the downlink UTRA Absolute RF Channel Number (UARFCN). This determines at what frequency the test set's RF generator will transmit the downlink signal.

The relationship between UARFCN and downlink frequency is described in 3GPP TS 25.101 section 5.

# In order to ensure a Frequency Band Indicator of Band V is sent in SIB5 when DL Channel is set to any of these UARFCNs, set Frequency Band Indicator State to On and Band Arbitrator to Band V .

+ In order to ensure a Frequency Band Indicator of Band VI is sent in SIB5 when DL Channel is set to any of these UARFCNs, set Frequency Band Indicator State to On and Band Arbitrator to Band VI .

* Ensure that the Transmit SIB5bis parameter is set accordingly for your UE.

When in FDD Test operating mode, the downlink frequency can also be set by setting RF Gen Freq Ctrl to Manual and then manually entering the RF Gen Freq .

To set the downlink channel number via GPIB command, see CALL:CHANnel .

Operating Considerations

  • This setting cannot be changed while in active cell operating mode. Attempting to change this setting while in this mode results in an error and the test set rejects the change. Use the Cell Off operating mode when changing this setting. See CALL:OPERating to select operating modes.
  • To hand over to a new downlink channel while on a connection, you must perform a Physical Channel Reconfiguration , Transport Channel Reconfiguration or Radio Bearer Reconfiguration . After successful completion of a handover to a new DL UARFCN, the DL Channel setting is overwritten with the value of the handover downlink channel .
  • If the DL Channel setting results in an UL/DL offset of less than 30 MHz when compared with the Uplink Channel setting, the warning message "Performance not specified for UL/DL frequency offset <30 MHz" is issued.
