Positive or negative frequency offset to be added to the specified frequencies is indi-
vidually selectable for each carrier in uplink and downlik. In the scenario rx diversity
both DL and UL frequency offsets are interconnected.
The relation between operating band, frequency and channel number and the UL/DL
separation are defined by 3GPP (see
chapter 2.2.12, "Operating Bands"
Option R&S CMW-KS425 is required for the S and L operating bands.
Option R&S CMW- KB036 is required for frequencies over 3.3 GHz (OB22).
You can change the operating band and the channels in all main connection states.
For an established connection you can either change one parameter directly (the
R&S
CMW performs a physical channel reconfiguration) or you can perform an intra-
WCDMA handover to reconfigure several parameters, see
Remote command:
Dual Carrier Separation
If the dual carrier scenario is active, the center DL frequency of carrier 2 equals the
center frequency of carrier 1 plus carrier separation value. Exception: at the upper end
of an operating band, carrier 2 uses the center frequency of carrier 1 minus carrier sep-
aration value. If you configure one downlink channel, the other downlink channel is
configured automatically.
Use the value of 5 MHz for adjacent channels.
Note, that the dual carrier frequency separation cannot be edited during active call.
Remote command:
DB DC HSDPA
Parameter "DB DC HSDPA" enables dual carrier R9 HSDPA (non-adjacent carriers
with 21Mbps each) in the downlink with a multi-band support and single carrier HSUPA
in the uplink.
The user defined band settings (
Custom
) enables free selection of operating bands for
both carriers. Additionally also the pre-defined band combinations are available, as
described in the table below. For the setting of the downlink carrier 1, the assignment
of either band A or band B is possible.
Uplink applies the band of the downlink carrier 1.
Option R&S CMW-KS405 is required for the dual band dual carrier HSDPA operation.
