The subframes for CQI and PMI reporting are determined by the parameter "cqi-pmi-
ConfigIndex". This parameter is configurable. Via a mapping table, the "cqi-pmi-Config-
Index" determines the reporting period N
p
and the reporting offset N
OFFSET,CQI
.
The subframes for RI reporting are determined by the parameters "M
RI
" and "N
OFF-
SET,RI
". The LTE signaling application uses "M
RI
" = 1 and "N
OFFSET,RI
" = -1.
This means, that the subframes for RI reporting are located immediately before the
subframes for CQI/PMI reporting.
If you want to evaluate reports for PCC and SCC, the carriers must use different sub-
frames for reporting. The carrier configurations must not overlap. This is also important
for scheduling types with a DL configuration that reacts to the reports, for example
"Follow WB CQI".
Example, dual-carrier FDD, wrong configuration:
PCC: "cqi-pmi-ConfigIndex" = 3 means offset = 1, period = 5
SCC: "cqi-pmi-ConfigIndex" = 9 means offset = 2, period = 10
The following table shows the resulting configuration for two frames. There is a colli-
sion in subframe number 1, with CQI/PMI reporting for the PCC and RI reporting for
the SCC.

Example, dual-carrier FDD, correct configuration:
PCC: "cqi-pmi-ConfigIndex" = 3 means offset = 1, period = 5
SCC: "cqi-pmi-ConfigIndex" = 5 means offset = 3, period = 5
The following table shows the resulting configuration. There is no collision.
