HSPA handovers
To support the HSPA tests and sub-test conditions specified in the 3GPP standards, the
transport channel reconfiguration procedure allows you to change HSPA parameters while on
a live connection. ßc, ßd, ΔACK, ΔNACK, ΔCQI, CQI feedback cycle (k), CQI repetition factor,
Ack-Nack repetition factor, and default DPCH offset (DOFF) parameters can all be modified
without dropping the HSPA connection. In addition, when using the user-defined
DL configuration for HSDPA in RB test mode, the number of HARQ processes and UE IR
buffer size can be changed on a live HSDPA connection to provide flexibility in testing
multiple configurations.
The radio bearer reconfiguration allows handover from a CS domain or CS/PS domain HSDPA
RB test mode connection or HSPA RB test mode connection to a (non-HSDPA/non-HSPA)
symmetrical RMC. The radio bearer reconfiguration also allows you to change many other
network parameters as part of the reconfiguration.
You can also handover between channels within a band and between bands using the
physical channel reconfiguration procedure. This allows you to test channels in the low,
middle, and high frequency portions of each UE-supported band without dropping the
HSPA connection.

Inter-system handovers
Almost all UE supports multiple formats today. To speed the process of testing multiple
formats with call processing, you can perform handovers from HSPA to GSM, and from
HSPA to W-CDMA. If your test plan requires testing HSPA followed by GSM, GPRS, and/or
EGPRS, you can hand over from an HSPA FRC to GSM test mode using the system handover.
If your test plan requires testing W-CDMA as well, you can hand over from an HSPA FRC
to a W-CDMA RMC, then use the existing W-CDMA RMC to GSM test mode system handover
to test GSM, GPRS, and/or EGPRS.

HSDPA user-defined downlink
Verify your device’s HSDPA throughput at the MAC-hs or MAC-ehs level with the user-
defined downlink (DL) in E1963A Option 403, 405, 423, 433, and 435. Verify HS-DSCH
category 15-20 HSDPA MIMO devices through to providing up to a 28 Mbps or 42 Mbps
radio bearer (RB) test mode signal. Set the configuration’s flexibly of HSDPA MIMO state,
each antenna channel configuration, the number of transport blocks and active HS-PDSCHs,
each transport block size index, modulation type of each transport block, inter-TTI, number
of HARQ processes, and UE incremental redundancy (IR) buffer size. Configure the E5515C/E
to provide up to a 42 Mbps RB test mode signal for testing HS-DSCH category 24 dual carrier
or dual band dual carrier devices.
