correctly configure itself to accept the downlink data (in this case, the format for the 12.2k RMC).

- the power level out of the test set must be high enough for the UE to receive the downlink

Downlink Channel Settings

The downlink signal consists of the following channels:
• Common pilot channel (CPICH): Used by the UE (mobile station) to find the primary scrambling code and
to help determine its transmit power during open loop power control.
• Primary common control physical channel (P-CCPCH): Contains the broadcast channel (BCH) that
normally provides system information to the UE. In FDD Test operating mode, this channel consists of
pseudo-random bit sequence (PRBS) data and a valid system frame number (SFN).
• Synchronization channel (SCH): Includes the primary and secondary synchronization channels (PSC and
SSC) that contain timing information to allow the UE to synchronize to the test set (or base station).
• Page indicator channel (PICH): Used to alert the UE that it is being paged. In FDD test mode, the test set
only provides a user specified bit pattern to allow the operator to verify that the UE is correctly decoding
this channel.
• Dedicated physical channel (DPCH): Contains the dedicated physical control channel (DPCCH) which
includes the transmit power control (TPC) and transmit format combination indicator (TFCI), and the
dedicated physical data channel (DPDCH) which contains the user data (which is always the 12.2 kbps
RMC for this test mode).
The relative level, desired level, spreading factor, and channel code for each of these channels, is displayed in
the Downlink Code Channel Information window on the test set.
- The UE must be set to receive the downlink signal on this channel.
- The UE must be set to transmit an uplink signal on this channel.
- The UE must be set to expect the following code settings from the test set on

- The power level that the UE is expected to be transmitting at.
