1.5.11 WCDMA/GERAN: Power
and Network
Optimizations – Frame
Early Termination for Power
Optimization
With pragmatic reception approach,
decode partial TTI and terminate frame
early to reduce power consumption
1.5.12 WCDMA/GERAN:
Protocols – MRAB-Pack-1
Enhancements
These UE enhancements will reduce
Multi-RAB Call Drops. The following
optimizations are planned under
MRAB-Pack-1: 1) Configuration of the
minimum set of TFCs: Optimize the way
that PS-only TFCs are selected for UL
transmission in power limited conditions(2
flavors) 1-EUL) Smart application of
minimum E-TFCI : Optimize utilization of
Minimum E-TFCI in power limited
conditions 4) MRAB Back-off: Preventing,
or reducing the establishment of data
connections on top of existing voice
connections in power limited conditions 6)
TVM Back-off : Blocking traffic volume
events (Event 4a) for MRAB calls in power
limited conditions
1.6 Modem (UMTS)

physical layer throughputs up to 42 Mbps
1.6.5 HSUPA 10ms TTI (2 Mbps) HSUPA 10 ms TTI up to 2 Mbps in UL
physical layer
1.6.6 HSUPA 2ms TTI (5.76
Mbps)
HSUPA 2ms TTI up to 5.76 Mbps in UL
physical layer
1.6.7 E-FDPCH E-FDPCH Rel-7 enhancement to the
Rel-6 FDPCH (fractional DPCH) in soft
handover scenarios; fractional DPCH was
added in Rel-6 to optimize the
consumption of downlink channelization
codes - Allowing more users to share the
channel
1.6.8 Enhanced L2 Support for flexible sized PDUs at RLC DL
and PDU segmentation at MAC-HS level,
on the HSDPA downlink to allow for higher
data rates in Rel-7
1.6.9 CPC-DTX Allows for breaks in transmission during
