PN Offset Programming Information
FEB 2005 1X SC 4812T Lite BTS Optimization/ATP B-1
PRELIMINARY
PN Offset Background
All Channel Elements transmitted from a BTS in a specific 1.25 MHz
CDMA Channel are orthogonally spread by 1 of 64 possible Walsh Code
Functions; additionally, they are also spread by a Quadrature Pair of PN
Sequences unique to each sector.
Overall, the mobile uses this to differentiate multiple signals transmitted
from the same BTS (and surrounding BTS) Sectors, and to synchronize
to the next strongest sector.
The PN Offset per Sector is stored on the BBX Cards, where the
corresponding I and Q Registers reside.
The PN Offset Values are determined by BTS Sector (Antenna) based on
the applicable CDF Data Field Content. A breakdown of this
information is found in Table B-1.
PN Offset Usage
There are three basic RF Chip Delays currently in use. It is important to
determine which RF Chip Delay is valid to be able to test the BTS
Functionality. This can be done by ascertaining if the CDF FineTxAdj
Value was set to “on” when the MCC was downloaded with “image
data”.
The
FineTxAdj Value is used to compensate for the Processing Delay
(approximately 20 mS) in the BTS using any type of mobile meeting
IS–97 Specifications.
Observe the following guidelines:
S If the FineTxAdj Value in the CDF is 101 (65 HEX), the FineTxAdj
has not been set. The I and Q Values from the 0 Chip Delay Column
of Table B-1 MUST be used.
If the
FineTxAdj Value in the CDF File is 213 (D5 HEX), FineTxAdj
has been set for the 14 Chip Delay column of Table B-1.
S If the FineTxAdj value in the CDF File is 197 (C5 HEX), FineTxAdj
has been set for the 13Chip Delay column of Table B-1.
CDF File I and Q Values can be represented in DECIMAL
or HEX.
If using HEX, add 0x before the HEX Value.
If necessary, convert HEX values in Table B-1 to decimal
before comparing them to CDF File I and Q Value
Assignments.
NOTE
– If a Qualcomm Mobile is used, select I and Q Values from the
13–Chip Delay column of Table B-1.
– If a mobile is used that does not have the “One Chip Offset”
problem (any mobile meeting the IS–97 Specification), select from
the 14–Chip Delay column of Table B-1.
