More Efficient Voice to Support More Data

WCDMA+ Triples Voice Spectral Efficiency

To free up resources for data

Can Free Up ~2/3 of a Carrier for HSPA+ Data While supporting the same voice capacity as WCDMA today

Ensures High Quality, Reliable, Ubiquitous Voice WCDMA+ builds on proven WCDMA circuit switched voice

WCDMA+: The Secret Sauce

RADIO LINK ENHANCEMENTS1

1) Reduces overhead—more power left to support more usersSuch as slower power control (750 MHz) and removal of dedicated downlink pilot

2) Less energy to transmit a voice frame—less interference and higher capacitySuch as early voice frame termination2

EVS WB(5.95k)

AMR(12.2k) Higher Capacity and

Voice Capacity

1Applies both to downlink and uplink, uplink improvements also needed to enhance uplink data capacity. 2The 20 ms voice-frame transmission can be terminated as soon as it is successfully decoded, compared continued to repeating all packets the full 20ms frame. 2EVS = Enhanced Voice Services, with a source controlled variable bit-rate mode.
