If the resulting accumulated power would be smaller than the RMS output power of the
generator, this gap is filled by OCNS channels, see
chapter 2.2.10.5, "Orthogonal
Channel Noise Simulator (OCNS)" , on page 40.
2.2.11 Connection Types
You can set up a connection in the CS domain and/or a connection in the PS domain.
The following connection types are supported:
●
CS domain only:
–
Voice call or video call, call content (voice / video) is looped back to the UE
– Signaling Radio Bearer (SRB)
– Reference Measurement Channel (RMC)
●
PS domain only:
–
Mobile terminated HSPA test mode connection
UL/DL = R99/HSDPA or HSUPA/HSDPA
– Mobile originated end to end packet data connection
UL/DL = R99/R99 or HSUPA/R99 or R99/HSDPA or HSUPA/HSDPA
●
CS + PS domain:
–
CS: RMC connection
PS: mobile terminated HSPA test mode connection
In reduced signaling mode only RMC connections and mobile terminated HSPA test
mode connections are supported.
For RMC, SRB and HSPA test mode connections additional information is provided in
the following sections.
For end to end packet data connections see chapter 2.2.4, "End to End Packet Data
Connections" , on page 23.
2.2.11.1 Reference Measurement Channel (RMC)
The data content of the 3GPP downlink RMC is defined on transport channel level
according to 3GPP TS 25.101. The data sequence to be transferred is directly fed into
the Dedicated Traffic Channel (DTCH) and the Dedicated Control Channel (DCCH).
The transport channels are channel coded, multiplexed and mapped onto a Dedicated
Physical Channel (DPCH) with variable data rate (see figure below).
The downlink reference measurement channel generated in this way is to be used for
various transmitter and receiver tests specified e.g. in 3GPP TS 25.101 and 34.121.
The following example illustrates the generation of a 3GPP reference measurement
channel from the DTCH and DCCH transport channels and lists the physical and trans-
port channel parameters for an information bit rate of 12.2 kbps. For other bit rates
refer to specification 3GPP TS 25.101.
