4.3.7 RRI Channel Output Power
Last updated: June 16, 2006
Definition
For access terminals supporting Subtype 0 or Subtype 1 Physical Layer, the RRI Channel is transmitted over the first 256 chips of every slot during a connection. The RRI Channel punctures the Pilot Channel and both channels are transmitted at the same power level. For access terminals supporting Subtype 2 Physical Layer, the RRI Channel is transmitted throughout the whole slot at a different code channel from the Pilot Channel at a power level RRIChannelGain relative to the Pilot Channel power level.
This test verifies that the RRI Channel is transmitted at the same power level as the Pilot Channel for access terminals supporting Subtype 0 or Subtype 1 Physical Layer or that the RRI Channel is transmitted at a power level of RRIChannelGain relative to the Pilot Channel power level.
Test 1 is applicable only to access terminals that support Subtype 0 or Subtype 1 Physical Layer. Test 2 is applicable only to access terminals that support Subtype 2 Physical Layer.
Method of Measurement
-
Connect the access network emulator to the AT.
-
Set up a Test Application session and open an RTAP connection (for Subtype 0 or 1 Physical Layer).
-
Set Î
or
to -75 dBm/1.23 MHz.
-
Test 1: Measure Delta
RRI/Pilot
.
-
Test 2: Set up a Test Application session and open an RETAP connection (for Subtype 2 Physical Layer).
-
Configure the Test Application RETAP so that the Reverse Link Data Channel is transmitted at the 256-bit payload. The Transmission Mode is High Capacity with HiCapT2PTransition256 set to 0x3 (4 sub-frames) and HiCapTerminationTarget256 set to 0x3 (4 sub-frames).
-
Set the RRIChannelPowerParameters Attribute of the Subtype 3 Reverse Traffic Channel MAC Protocol with RRIChannelGainPreTransition3 set to 0xA (-6 dB).
-
Measure the power of the Pilot and RRI Channels.
Minimum Standard
Test 1: 10 log
10
(Delta
RRI/Pilot
) shall be within +/- 0.25 dB.
Test 2: the difference of 10 log
10
(Power
RRI
/Power
Pilot
) and RRIChannelGain (dB) shall be between -0.25 and +0.25 dB. (The current standard is wrongly to say between -6.25 and -5.75 dB which will be fixed soon in the next release)
