Example configurations for DCHSDPA in WN6.0 EP1
Slides includes examples how 2+2+2, 3+3+3 and 3+3 configurations can be configured
with Tcell parameters in single carrier HSDPA case and how same configurations shall be
configured when DC-HSDPA is used. Slides also justify why DC-HSDPA can not be
supported with 2+2+2+2 and 3+3+3+3 configurations in WN6.0 EP1.
Example: 2+2+2 configuration with single carrier HSDPA (2 x EfficientBB
schedulers, 1 scheduler per frequency layer), current WN6.0 implementation

that f1 can not be DC-HSDPA

Note:
Even LCG limitation is not
visible here (LCGs not needed
as only 6 cells) HSDPA
scheduler in WN6.0 EP1 does
not support more than 2 DCHSDPA cells (intention is to
avoid extra effort in WN6.0 EP1
and so HSDPA scheduler
implementation is kept as
simple as possible)
