1x Voice Capacity Advantage over UMTS Continues to Widen


1x Advanced Feature Set

• Available features In MSM/standard today– EVRC-B vocoder– Mobile Receive Diversity– QLIC (quasi-linear interference cancellation)– Quasi-orthogonal functions (QOF) for increase in code space

• Future receiver enhancements (no impact to standard) – Advanced QLIC (MSM enhancements)

• Neighbor set cancellation• Cancellation for QoF

– Reverse link interference cancellation (RL IC) (new CSM)

• Proposed physical layer enhancements (new radio configuration) – Smart blanking of 1/8 rate frames– More efficient closed-loop power control– Reverse link early termination– Forward link early termination


Available Features Enable 60% Capacity Increase

• EVRC-B vocoder enables lower data rates with same voice quality as EVRC

• MRD or QLIC increase received SINR resulting in less FL power per user

• To capitalize on the enhanced capacity*, additional Walsh Codes needed– QOF however contributes to increasing FL interference

• Smart Blanking of 1/8th rate frames reduces FL and RL tx power used for background noise

• Reducing power control commands allows significant savings in power per user

– Power control commands sent at power of full-rate frames – Soft Handoff users consume additional power for PC commands

• Early decode of frames allows system to further reduce transmit power and other-cell interference

Rev A: Faster Connections, Seamless Server Selection

• Faster Connection Times– Quick Connect

• Resource allocation tasks performed in parallel– Fast Paging

• Device can come out of sleep more often than that possible in Rel 0 systems– Faster Access Channel

• Device can establish connection faster– Improved Control Channel

• System can send overhead messages more often and with smaller packets

• Seamless Server Selection– As device moves in the new coverage area, it can send an early indication of

cell change to the network (via DSC channel)– Forward link data is sent to the new cell ahead of time, so there is no

interruption (transmit delay) caused by the cell change
